Description

Technical Field

[0001] The invention relates to a pipeline joint, in particular to a quick-install clamp and a sealing ring thereof. Background Art

[0002] Pipe fittings are usually used to connect two pipe components. Pipe components can be pipes or fittings such as elbows, valves, reducers and tees. Quick-install pipe fittings are the latest pipe component connectors on the market. Figure 1 As shown in the figure, the gasket 1 and fasteners such as bolts and nuts can be preassembled on the housing 2. When in use, there is no need to remove the gasket 1 and the fasteners. Instead, the pipe element 3 can be directly inserted into the clamp to quickly complete the docking of the clamp and the two pipe elements 3.

[0003] By pre-assembling the gasket 1 and fasteners to the housing 2, the quick-install pipe connector makes the assembly process faster. The user can directly insert the pipe component 3 into the pipe connector and position the engagement key 21 of the housing 2 in the corresponding engagement groove 31 of the pipe component 3 without disassembling and reassembling the parts, which greatly reduces the installation time. This design simplifies the connection process. Since the gasket 1 and fasteners are already in place, the operator only needs to focus on the positioning of the pipe component 3, making it easy for ordinary workers to use. The pre-assembled gasket 1 and fasteners reduce the chance of incorrect assembly, such as incorrect alignment or missing components, which may cause leaks or connection failures.

[0004] like Figure 1 As shown in the figure, the gasket 1 includes a base portion 11, a central protrusion 12 and two abutting ends 13, wherein the base portion 11 is used to abut against the inner wall of the housing 2, the central protrusion 12 is used to define the distance of the pipe element 3 inserted into the clamp, and the two abutting ends 13 are used to abut against the outer wall of the pipe element 3 to achieve sealing.

[0005] However, due to manufacturing tolerances, the pipe components have different diameters. The existing gasket 1 is designed based on the size of a fixed-size pipe component 3. When the pipe component 3 has a small diameter, the two abutting ends 13 of the gasket 1 have a large inner diameter, and thus cannot achieve a tight seal on the insertion end of the pipe component 4. When the pipe component 3 has a large diameter, a portion of the gasket 1 may be squeezed out of the housing 2.

[0006] In addition, when installing two pipe components 3 to the pipe joint, the insertion end of one pipe component 3 is first inserted into the pipe joint and the insertion end is abutted against the central protrusion 12. Because the diameters of the pipe component 3 and the gasket 1 are not compatible, especially when the diameter of the pipe component 3 is small, the gasket 1 will be offset, which will cause the central protrusion 12 to be eccentric and not in the expected central position. At this time, because at some installation sites, the position where the pipe element 3 and the pipe joint are connected may be above the operator's head, the operator may not be able to observe the connection between the pipe element 3 and the pipe joint. When the insertion end of another pipe element 3 is inserted into the pipe joint, because the central protrusion 12 deviates from the center position, the end position of the insertion end of the other pipe element 3 is not the expected position, which will cause the position of the engagement groove 31 of the other pipe element 3 and the engagement key 21 on the housing 2 to not correspond, and the user cannot observe the mismatch between the engagement groove 31 and the engagement key 21, resulting in the operator needing to spend more time and energy to adjust and install the other pipe element 3 to the pipe joint.

[0007] That is to say, when the central raised portion 12 is off-center, the engagement groove 31 of the second pipe element 3 cannot be properly aligned with the engagement key 21 on the housing 2. At the installation site, operators usually rely on intuitive observation or feel to ensure the accuracy of the connection. If the mismatch occurs in an invisible position, the operator needs to rely on repeated attempts and adjustments to complete the docking. In this case, the complexity and uncertainty of the installation process are significantly increased, which prolongs the installation time and increases the possibility of errors. And because the mismatch occurs and is difficult to detect, the operator needs to spend more time and energy to adjust the position of the pipe element 3. This not only prolongs the installation process, but also increases labor costs. If these problems are not discovered and corrected in a timely manner during the installation process, it may eventually lead to the stability and safety of the entire pipeline system being compromised. Summary of the invention

[0008] One advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein the sealing ring contacts the inner wall of the housing of the quick-release clamp via a protrusion, so that the quick-release clamp can flexibly adapt to the diameter deviation of the pipeline component. In particular, when the diameter of the pipeline component is slightly smaller, the design can ensure that the sealing ring fits tightly with the pipeline component, thereby improving the sealing of the connection.

[0009] Another advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein the convex design of the sealing ring can automatically adjust to adapt to the pipe components of different diameters, and the installation process becomes easier. The operator no longer needs to make frequent adjustments, and can directly insert two pipe components to complete the docking, which reduces the installation time and labor intensity.

[0010] Another advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein when the diameter of the pipeline element is slightly smaller, since a protrusion is provided on the outer surface of the sealing ring, the inner diameter of the sealing ring is reduced relative to a traditional sealing ring, so that the sealing ring of the present invention can adapt to the pipeline element with a slightly smaller diameter and achieve a tight seal.

[0011] Another advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein when the diameter of the pipeline element is slightly larger, since a protrusion is provided on the outer surface of the sealing ring, the inner diameter of the sealing ring is reduced relative to a traditional sealing ring, thereby providing more space for the sealing ring in the housing, preventing a portion of the sealing ring from being pushed out of the housing when the insertion end of the pipeline element is inserted into the housing.

[0012] Another advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein when the diameter of the pipeline element is slightly smaller, the sealing ring will not have its thrust portion eccentric due to loose fitting, and when the diameter of the pipeline element is larger, a part of the sealing ring is prevented from being pushed out of the shell, which not only ensures the sealing effect of the sealing ring, but also ensures the reliability of the installation between the engagement groove of the pipeline element and the engagement key of the quick-release clamp.

[0013] Another advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein the thrust portion of the sealing ring will not deviate, so that the insertion end of the first pipeline component can be accurately positioned when it is installed into the quick-release clamp and abuts against the thrust portion, so that the insertion end of the subsequent second pipeline component can be easily inserted to the expected position, thereby quickly completing the docking of the two pipeline components with the quick-release clamp. Due to the accurate positioning of the insertion end of the first pipeline component, the subsequent installation of the pipeline components becomes faster without the need for additional adjustment or correction, thereby significantly improving the installation efficiency and reducing the operation time.

[0014] Another advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein the quick-release clamp can still ensure that the engagement groove of the second pipeline component and the engagement key of the housing are accurately aligned even in an installation situation where the operator cannot easily observe the details of the engagement between the pipeline component and the quick-release clamp. This feature reduces the difficulties caused by the operating environment restrictions and makes the installation process smoother.

[0015] Another advantage of the present invention is that it provides a quick-connect clamp and its sealing ring, which provide significant advantages in installation situations where visibility is limited or the operator's access to the connection details is limited. Specifically, the design ensures that the engagement groove of the second pipeline component can still be accurately aligned with the engagement key of the housing even when the operator cannot directly observe or operate the connection. In other words, this function is particularly important in environments where space is limited, light is insufficient, or the operator must work overhead or other inconvenient positions. By achieving a precise and secure connection under these conditions, the present invention greatly reduces the possibility of errors such as misalignment or incomplete engagement that may compromise the integrity of the connection.

[0016] Another advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein the inner surface of the shell of the quick-release clamp may have a protrusion, and the protrusion on the inner surface of the shell is in contact with the outer surface of the sealing ring, so that the inner diameter of the sealing ring is reduced relative to a traditional sealing ring, thereby enabling the quick-release clamp to flexibly adapt to the diameter deviation of the pipeline component.

[0017] Another advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein the sealing ring contacts the inner wall of the shell of the quick-release clamp via a protrusion, so that when the quick-release clamp is in a pre-installed state, the sealing ring plays a role in supporting the shell, and the required volume is smaller, thereby facilitating manufacturing and saving costs.

[0018] Another advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein the area where the inner surface of the shell of the quick-release clamp contacts the outer surface of the sealing ring is an arc surface, and the inner diameter of the outer arc surface of the sealing ring is relatively large, so that no matter whether the diameter of the pipeline element is slightly larger or smaller, the design can ensure that the sealing ring fits tightly with the pipeline element and improve the installation efficiency.

[0019] Another advantage of the present invention is to provide a quick-release clamp and a sealing ring thereof, wherein the pressing surface of the sealing ring of the quick-release clamp facing the pipe element includes multiple sections with different inclination angles, especially the portion adjacent to the pipe element has a larger inclination angle, while the portion relatively far from the pipe element has a smaller inclination angle, so that when the diameter of the pipe element is slightly larger, the compression amount of the sealing ring is reduced, and when the diameter of the pipe element is slightly smaller, the sealing ring is tightly fitted to the pipe element and will not deviate.

[0099] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0100] like Figures 2 to 7The quick-release clamp according to the first preferred embodiment of the present invention is shown, which includes two or more housings 100, two or more connecting elements 200 preassembled on the housings 100, and a sealing ring 300 preassembled in the housings 100, wherein the quick-release clamp of the present invention is used to connect with two pipeline components 400, wherein the pipeline components 400 can be pipes or pipe fittings such as elbows, valves, reducers and tees. In this embodiment, the two pipeline components 400 are each a pipe as an example for description.

[0101] In the present invention, typically, the quick-release clamp includes two or three housings 100. In this embodiment, the quick-release clamp includes two housings 100. These housings 100 surround an opening 101 for inserting the pipeline element 400, and sleeve and fix the insertion end 401 of the pipeline element 400.

[0102] The two housings 100 can be made of metal or plastic, can be coupled to each other and form a substantially annular structure, and define an inner cavity 102 to accommodate the insertion ends 401 of the two pipe elements 400. Each housing 100 has a C-shape, and has engagement keys 103 formed on opposite sides. The insertion ends 401 of the corresponding pipe elements 400 can be grooved pipe elements, which have engagement grooves 402 engaged with the engagement keys 103. When the quick-release clamp is connected to the two pipe elements 400, the engagement keys 103 of the housing 100 are respectively engaged in the engagement grooves 402 of the corresponding pipe elements 400, thereby achieving the connection between the two pipe elements 400 and the quick-release clamp.

[0103] In this embodiment, the two housings 100 are symmetrical structures and are preassembled together by two connecting elements 200. The function of these connecting elements 200 is to connect the two housings 100 tightly together to form an integral structure to ensure that they do not loosen or shift during use. The connecting elements 200 may include bolts and nuts, buckles, hinges, etc., depending on the size and application of the quick-release clamp. Preferably, the two connecting elements 200 include at least one fastener 210 such as a bolt and nut for fastening the two housings 100. In this embodiment, the two connecting elements 200 can each be implemented as a bolt and nut. In other modified embodiments, one connecting element 200 can be a bolt and nut, and the other connecting element 200 can be a buckle or a hinge.

[0104] The sealing ring 300 is made of an elastic material, such as rubber, silicone, polytetrafluoroethylene, polyurethane, thermoplastic elastomer, etc., and is pre-assembled inside the housing 100. The function of the sealing ring 300 is to open the two housings 100 before assembling the pipeline element 400 to the quick-release clamp, so that the size of the opening 101 can allow the insertion end 401 of the pipeline element to be inserted into the inner cavity 102 formed by the two housings 100 of the quick-release clamp, and after the pipeline element 400 is assembled to the quick-release clamp, the sealing ring 300 is tightly fitted between the housing 100 and the pipeline element 400 to ensure the sealing of the connection between the quick-release clamp and the pipeline element 400.

[0105] like Figures 4 to 6 As shown, the sealing ring 300 includes a base portion 310, a thrust portion 320 extending from the central area of ​​the base portion 310, and two pressing end portions 330 extending from both sides of the base portion 310. The base portion 310 is an annular base 310, the thrust portion 320 can be a thrust ring, or can include multiple thrust segments in a circumferential direction, and the two pressing end portions 330 can each be a pressing ring, or can include multiple pressing segments in a circumferential direction.

[0106] The base portion 310 is the basic structural part of the sealing ring 300, which is an annular structure used to support the entire sealing ring 300. The annular base portion 310 ensures that the sealing ring 300 can be firmly installed inside the housing 100 of the quick-release clamp, and provides a stable support foundation for the thrust stop portion 320 and the pressing end portion 330.

[0107] The base portion 310 provides uniform pressure distribution through its annular design, so that the sealing ring 300 can remain stable during the installation of the pipe element 400. At the same time, the structure of the base portion 310 enables the sealing ring 300 to adapt to pipe elements 400 of different diameters, ensuring the versatility of installation, which will be further described in detail below.

[0108] The thrust portion 320 is a key component in the sealing ring 300, and is responsible for providing thrust force for the pipeline element 400 during the installation process. In other words, the main function of the thrust portion 320 is to press against the insertion end 401 of the pipeline element 400 during the process of inserting the insertion end 401 of the pipeline element 400 into the housing 100 of the quick-release clamp to ensure its accurate position. By providing a stable contact surface, the thrust portion 320 ensures that the pipeline element 400 will not be displaced by external force, thereby ensuring the sealing and docking accuracy. The two pressing ends 330 generate additional pressing force between the corresponding pipeline element 400 and the housing 100, thereby enhancing the contact tightness between the sealing ring 300 and the pipeline element 400.

[0109] During the installation of the two pipeline components 400, when the insertion end 401 of one pipeline component 400 is inserted into the housing 100 from one side to reach the inner cavity 102 thereof, the thrust portion 320 blocks the further insertion of the pipeline component 400, thereby ensuring that the insertion end 401 of the first pipeline component 400 is inserted to the expected depth of abutting against the thrust portion 320. In this way, when the second pipeline component 400 is also inserted into the housing 100, it reaches the other side opposite to the thrust portion 320 and is positioned, thereby ensuring that the engagement groove 401 of the corresponding pipeline component 400 corresponds to and engages with the engagement key 103 of the corresponding housing 100.

[0110] That is, when the insertion end 401 of the first pipe element 400 is inserted from one side of the housing 100, it gradually enters the inner cavity 102 of the housing 100. In this process, the pipe element 401 is supported and guided by the annular base 310 and the pressing end 330 of the sealing ring 300 to ensure that it is smoothly inserted without deviation.

[0111] When the insertion end 401 goes deeper, it will contact the thrust portion 320. At this time, the thrust portion 320 acts as a barrier to prevent the pipeline element from continuing to be inserted forward. Through this barrier, the thrust portion 320 ensures that the insertion end 401 of the pipeline element 400 can reach a predetermined depth and accurately locate at a designated position in the inner cavity of the housing 100. The accuracy of this positioning is very important, which ensures that the engagement groove 401 of the first pipeline element 400 and the engagement key 103 of the housing 100 can be accurately aligned. Accurate alignment not only ensures a stable connection of the pipeline element, but also provides a basis for subsequent sealing.

[0112] Subsequently, the second pipeline element 400 is inserted from the opposite side of the housing 100. The insertion process of the second pipeline element 400 is similar to that of the first one, and it will also be supported and guided by the sealing ring 300. When the insertion end 401 of the second pipeline element 400 contacts the opposite side of the thrust portion 320, it will also be blocked at a predetermined depth position. Since the thrust portion 320 is located in the middle of the two pipeline elements 400, it is ensured that the insertion depth of the second pipeline element 400 is substantially the same as that of the first pipeline element 400. In this way, the engagement groove 401 of the second pipeline element 400 will also be accurately aligned with the engagement key 103 of the housing 100. Through this process, it is ensured that the engagement grooves 401 of the two pipeline elements 400 correspond to and tightly engage with the engagement keys 103 of the housing 100, forming a firm connection.

[0113] In the present invention, the design of the thrust portion 320 enables the positioning of the two pipeline components 400 during the installation process to be more accurate. By providing a stable thrust force, the pipeline components 400 are prevented from shifting due to improper operation during the installation process. This not only improves the installation accuracy, but also reduces the risk of sealing failure caused by misalignment, thereby improving the reliability of the entire pipeline system.

[0114] In this embodiment of the present invention, the sealing ring 300 is formed of a base portion 310 and two pressing end portions 330 to form an outer action surface 3000, which is used to abut against the inner surface 104 of the housing 100. An adaptive sealing structure 340 is formed on the action surface 3000 to enable the sealing ring 300 to adapt to changes in the diameter of the pipeline element 400 and prevent eccentricity of the thrust portion 320.

[0115] More specifically, if Figure 5 and Figure 6 As shown in the figure, the outer action surface 3000 includes a central action surface portion 3001, two first action surface portions 3002 extending outwardly from both sides of the central action surface portion 3001, and two second action surface portions 3003 extending from the first action surface portions 3002, respectively, wherein the angle between the two first action surface portions 3002 and the central action surface portion 3001 is an obtuse angle, and the two second action surface portions 3003 extend inwardly from the first action surface portion 3002, and the angle between the two second action surface portions 3003 and the corresponding first action surface portion 3002 can be an obtuse angle, a right angle or an acute angle.

[0116] The first action surface portion 3002 extends obliquely from the central action surface portion 3001 in a direction away from the thrust portion 320 and forms a turning point 3005 at the position where it intersects with the central action surface portion 3001. The position where the second action surface portion 3003 intersects with the corresponding first action surface portion 3002 forms a turning point 3004. The second action surface portion 3003 extends obliquely or vertically from the corresponding first action surface portion 3002 in a direction close to the thrust portion 320. In this way, the outer action surface 3000 of the sealing ring 300 is formed with a convex structure through the arrangement of the extension direction of the first action surface portion 3002 and the corresponding second action surface portion 3003, that is, the adaptive sealing structure 340 includes the first action surface portion 3002, the second action surface portion 3003 and the turning point 3004 formed by the intersection of the first action surface portion 3002 and the corresponding second action surface portion 3003, that is, the turning point 3004 is formed at the angle between the first action surface portion 3002 and the corresponding second action surface portion 3003.

[0117] In this embodiment, each first action surface portion 3002 and each second action surface portion 3003 are schematically shown as having a planar structure. It can be understood by those skilled in the art that, in other variant embodiments, each first action surface portion 3002 and each second action surface portion 3003 may also have other surface structures, such as each being a curved surface, and two curved surfaces intersecting to form a turning point 3004.

[0118] When the quick-release clamp of the present invention is in a pre-assembled state and has not yet been used to connect with two pipe components 400, the sealing ring 300 is placed in the inner cavity 102 of the two shells 100, and the two turning protrusions 3004 on the outer side of the sealing ring 300 abut against the inner surface 104 of the corresponding shell 100, so as to open the shell 100 so that its opening 101 is larger to allow the corresponding pipe component 400 to be inserted.

[0119] like Figures 5 and 6 As shown in , the inner surface 104 of each shell 100 includes a central inner surface portion 1041, two first inner surface portions 1042 extending obliquely from both sides of the central inner surface portion 1041, and two second inner surface portions 1043 extending from the first inner surface portions, wherein each second inner surface portion 1043 can be a curved surface or an inclined surface, and each first inner surface portion 1042 is an inclined surface or an arc surface. In this embodiment, each first inner surface portion 1042 is an inclined surface and the angle between it and the central inner surface portion 1041 is an obtuse angle. It can be understood that each first inner surface portion 1042 can also be an arc surface in other modified embodiments. The central inner surface portion 1041 located in the central position can be a plane, an arc surface, or a plane with a groove.

[0120] In this embodiment of the present invention, the turning point 3004 is formed by the angle between the first active surface portion 3002 and the second active surface portion 3003, and is used to increase the elasticity and deformation capacity of the sealing ring 300, ensuring that the sealing ring 300 can fit tightly and maintain sealing properties under pipeline elements 400 of different diameters.

[0121] More specifically, because the sealing ring 300 of this embodiment of the present invention is provided with a convex position on its outer surface, compared with a traditional sealing ring of the same specification, the position of the pressing end 330 of the sealing ring 300 of the present invention is closer to the central axis inside thereof, so that the inner diameter formed by the pressing end 330 is equivalent to being reduced, so that the pressing end 330 can be pressed against the insertion end 401 of the pipe element 400 with a slightly smaller diameter, so that the sealing ring 300 of this embodiment of the present invention can adapt to the pipe element 400 with a slightly smaller diameter, and fit tightly to the insertion end 401 of the pipe element 400 to play a sealing role.

[0122] In addition, a gap 105 is formed between each of the two first action surface portions 3002 of the sealing ring 300 and the corresponding first inner surface portion 1042, and the two gaps 105 provide deformation space for the sealing ring 300. When the diameter of the pipe element 400 is slightly larger, when the insertion end 401 of the pipe element 400 is inserted into the housing 100 and the sealing ring 300, and the housing 100 is subsequently fastened by the fastener 210 in the connecting element 200, the sealing ring 300 is sandwiched between the pipe element 400 and the housing 100, and the deformation space provided by the gap 105 allows the sealing ring 300 to deform so as to adapt to the pipe element 400 with a slightly larger diameter.

[0123] When the quick-release clamp is in a pre-assembled state and not connected to the pipeline component 400, the sealing ring 300 is placed in the inner cavity 102 of the housing 100. At this time, the two turning convex points 3004 on the outside of the sealing ring 300 abut against the inner surface 104 of the housing 100, and the housing 100 is stretched open to increase the size of the opening 101, so that the corresponding pipeline component 400 can be smoothly inserted. This design not only simplifies the installation process, but also ensures the adaptability of the sealing ring 300, improves the sealing performance of the sealing ring 300, and prevents the eccentricity of the thrust portion 320.

[0124] More specifically, refer to Figure 7 As shown in FIG. 1 , when the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipe element 400 is slightly smaller, and the pressing end portion 330 of the sealing ring 300 has a smaller inner diameter than that of a conventional sealing ring, so that it can be closely fitted to the insertion end 401 of the pipe element 400 without causing the sealing ring 300 to deviate due to the pipe element 400 abutting against the inner side of the sealing ring 300, that is, to prevent the sealing ring 300 from being loosely fitted between the pipe element 400 and the housing 100 and being moved by the pipe element 400. 00, thereby deviating and eccentrically moving the thrust portion 320, so that the first pipeline component 400 enters the sealing ring 400 too deeply, thereby ensuring that the first pipeline component 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipeline component 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipeline component 400 can be aligned with the engagement key 103 of the corresponding housing 100 to complete the final assembly.

[0125] When the first pipeline element 400 is inserted into the housing 100 and the sealing ring 300, when the diameter of the first pipeline element 400 is slightly larger, because the base portion 310 of the sealing ring 300 has a smaller inner diameter than that of a traditional sealing ring, and the gap 105 formed between the two first action surface portions 3002 of the sealing ring 300 and the corresponding first inner surface portions 1042 provides space for the sealing ring 300, thereby ensuring that the first pipeline element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipeline element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that it is convenient for the engagement groove 402 of the second pipeline element 400 to be aligned with the engagement key 103 of the corresponding housing 100 to complete the final assembly, and the sealing ring 300 will not be partially squeezed out of the housing 100 due to insufficient space in the housing 100.

[0126] In addition, the two turning protrusions 3004 abutting against the inner surface 104 of the housing 100 are symmetrically arranged, so that when the insertion end 401 of the first pipe element 400 is inserted into one side of the housing 100, the turning protrusion 3004 located on the opposite side abuts against the inner surface 104 of the housing 100 to prevent the displacement of the sealing ring 300, thereby preventing the displacement of the thrust portion 320.

[0127] In the present invention, through the bidirectional blocking effect of the thrust portion 320, and the thrust portion 320 will not be eccentric due to the insertion of the pipeline element 400, the present invention can more accurately control the insertion depth of the two pipeline elements 400. Whether it is the first pipeline element 400 or the second pipeline element 400, it will automatically be positioned in the correct position when inserted in place, which ensures that the engagement grooves 401 of the two pipeline elements accurately correspond to the engagement keys 103 of the housing 100. Accurate positioning reduces the adjustment work during installation, so that the two pipeline elements 400 can be quickly and accurately connected to the quick-release clamp of the present invention, improving the overall installation efficiency.

[0128] In addition, the non-eccentric design of the thrust portion 320 of the present invention is not only to block the insertion action of the pipe component 400, but also to reduce the error during the installation process. It ensures that the pipe component 400 will not be poorly joined due to over-insertion or under-insertion. This design to prevent over-insertion is particularly important in complex operating environments or when the line of sight is limited.

[0129] In this embodiment of the present invention, the turning point 3004 between the first action surface portion 3002 and the second action surface portion 3003 contacts the inclined first inner surface portion 1042 of the housing 100, so that the sealing ring 300 can support the housing 100, and can adapt to the change of the diameter of the pipe element 400 and prevent the thrust portion 32 from being eccentric during the installation of the pipe element 400. Compared with the traditional sealing ring that uses the outer surface curve to completely fit the inner surface of the housing, the sealing ring has a smaller volume and reduces the cost.

[0130] like Figures 8 to 10 Shown is a quick-release clamp according to a second preferred embodiment of the present invention, which includes two or more housings 100 , two or more connecting elements 200 preassembled on the housings 100 , and a sealing ring 300 preassembled in the housings 100 .

[0131] The sealing ring 300 includes a base portion 310, a thrust portion 320, and two pressing end portions 330. The base portion 310 is an annular base 310. In this embodiment of the present invention, the sealing ring 300 is formed with the base portion 310 and the two pressing end portions 330 to form an outer action surface 3000 for abutting against the inner surface 104 of the housing 100. An adaptive sealing structure 340 is formed on the action surface 3000 to enable the sealing ring 300 to adapt to the diameter variation of the pipeline element 400 and prevent the eccentricity of the thrust portion 320.

[0132] More specifically, the outer active surface 3000 of the sealing ring 300 includes a central active surface portion 3001 and two side active surface portions 3006 extending integrally from opposite sides of the central active surface portion 3001 , respectively. The two side active surface portions 3006 can each be an inclined surface or an arc surface.

[0133] The inner surface 104 of each housing 100 includes a central inner surface portion 1041, two first inner surface portions 1042 extending obliquely from both sides of the central inner surface portion 1041, and two second inner surface portions 1043 extending from the first inner surface portion 1042, wherein each second inner surface portion 1043 may be a curved surface or an inclined surface, each first inner surface portion 1042 is an inclined surface or an arc surface, and in this embodiment, each first inner surface portion 1042 is an inclined surface, and the angle between the inclined surface and the central inner surface portion 1041 is an obtuse angle. It can be understood that each first inner surface portion 1042 may also be other curved surfaces in other variant embodiments. The central inner surface portion 1041 located in the central position may be a plane, an arc surface, or a plane with a groove, etc.

[0134] In this embodiment, the central action surface portion 3001 and the two side action surface portions 3006 on the outer side of the sealing ring 300 intersect to form two turning points 3005 , and each turning point 3005 abuts against the first inner surface portion 1042 of the corresponding housing 100 .

[0135] The sealing ring 300 further includes one or more protrusions 350 formed on the central action surface portion 3001, that is, the adaptive sealing structure 340 of this embodiment includes a protrusion 350 formed on the central action surface portion 3001. The protrusion 350 can be a hemispherical body, a conical boss, a cylindrical boss, a square boss, etc. Fig.10 As shown in FIG. 1 , the protrusion 350 has a gradually decreasing size in a direction toward the central inner surface portion 1041 .

[0136] More specifically, two protrusions 350 are integrally formed on both sides of the central action surface portion 3001 to abut against the corresponding central inner surface portion 1041 of the housing 100 in the pre-assembled state of the quick-release clamp. In addition, a first gap 1061 is formed between the two protrusions 350, the central action surface portion 3001 of the sealing ring 300 and the central inner surface portion 1041 of the housing 100, a second gap 1062 is formed between the turning point 3005, the central action surface portion 3001 located outside the protrusions 350 and the inner surface 104 of the housing 100, and a third gap 1063 is formed between the side action surface portion 3006 of the sealing ring 300 and the first inner surface portion 1042 of the housing 100.

[0137] In this embodiment of the present invention, when the quick-release clamp is in a pre-assembled state and is not connected to the pipeline component 400, the sealing ring 300 is placed in the inner cavity 102 of the housing 100. At this time, the two protrusions 350 on the outer side of the sealing ring 300 abut against the central inner surface portion 1041 of the inner surface 104 of the housing 100, and the housing 100 is stretched open to increase the size of the above-mentioned opening 101, so that the corresponding pipeline component 400 can be smoothly inserted. This design not only simplifies the installation process, but also ensures the adaptability of the sealing ring 300, improves the sealing performance of the sealing ring 300, and prevents the eccentricity of the thrust portion 320.

[0138] More specifically, when the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipe element 400 is slightly smaller. Since the protrusion 350 abuts against the inner surface 104 of the corresponding housing 100, the pressing end 330 of the sealing ring 300 has a smaller inner diameter than that of a conventional sealing ring, so that it can fit closely to the insertion end 401 of the pipe element 400 without causing the sealing ring 300 to deviate due to the pipe element 400 abutting against the inner side of the sealing ring 300. In other words, it is prevented that the sealing ring 300 is loosely fitted between the pipe element 400 and the housing 100 and is moved by the pipe element 400. The first pipe element 400 is offset by the action of the member 400, and the thrust portion 320 is eccentric, so that the first pipe element 400 enters the sealing ring 400 too deeply, thereby ensuring that the first pipe element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the fastening action of the fastener 210 in the connecting element 200.

[0139] When the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipe element 400 is slightly larger, because the base portion 310 of the sealing ring 300 has a smaller inner diameter than that of a conventional sealing ring, and the gaps 1061, 1062 and 1063 formed between the central action surface portion 3001 and the two side action surface portions 3006 of the sealing ring 300 provide space for the sealing ring 300, the first pipe element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the tightening action of the fastener 210 in the connecting element 200. The sealing ring 300 will not be partially squeezed out of the housing 100 due to insufficient space in the housing 100.

[0140] In addition, the two protrusions 350 abutting against the inner surface 104 of the housing 100 are symmetrically arranged, so that when the insertion end 401 of the first pipe element 400 is inserted into one side of the housing 100, the protrusion 350 located on the opposite side abuts against the inner surface 104 of the housing 100 to prevent the displacement of the sealing ring 300, thereby preventing the displacement of the thrust portion 320.

[0141] like Figures 11 to 13The quick-release clamp is shown as a modified embodiment of the second preferred embodiment of the present invention, which includes two or more shells 100, two or more connecting elements 200 preassembled on the shells 100, and a sealing ring 300 preassembled in the shell 100.

[0142] Correspondingly, the sealing ring 300 includes a base portion 310, a thrust portion 320, and two pressing end portions 330. The base portion 310 is an annular base 310. In this embodiment of the present invention, the sealing ring 300 is formed with the base portion 310 and the two pressing end portions 330 to form an outer action surface 3000 for abutting against the inner surface 104 of the housing 100. An adaptive sealing structure 340 is formed on the action surface 3000 to enable the sealing ring 300 to adapt to the diameter variation of the pipeline element 400 and prevent the eccentricity of the thrust portion 320.

[0143] More specifically, the outer active surface 3000 of the sealing ring 300 includes a central active surface portion 3001 and two side active surface portions 3006 extending integrally from opposite sides of the central active surface portion 3001 , respectively. The two side active surface portions 3006 can each be an inclined surface or an arc surface.

[0144] The inner surface 104 of each shell 100 includes a central inner surface portion 1041, two first inner surface portions 1042 extending obliquely from both sides of the central inner surface portion 1041, and two second inner surface portions 1043 extending from the first inner surface portions 1042, wherein each second inner surface portion 1043 may be a curved surface or an inclined surface, each first inner surface portion 1042 is an inclined surface, and in this embodiment, each first inner surface portion 1042 is an inclined surface, and the angle between the inclined surface and the central inner surface portion 1041 is an obtuse angle.

[0145] In this embodiment, the central action surface portion 3001 and the two side action surface portions 3006 on the outer side of the sealing ring 300 intersect to form two turning points 3005 , and each turning point 3005 abuts against the first inner surface portion 1042 of the corresponding housing 100 or has a slight gap.

[0146] The sealing ring 300 further includes one or more protrusions 350 formed on the central action surface portion 3001, that is, the adaptive sealing structure 340 of this embodiment includes a protrusion 350 formed on the central action surface portion 3001. The protrusion 350 can be a hemispherical body, a conical boss, a cylindrical boss, a square boss, etc. Fig.13 As shown in FIG. 1 , the protrusion 350 has a gradually decreasing size in a direction toward the central inner surface portion 1041 .

[0147] More specifically, two protrusions 350 are integrally formed on both sides of the central action surface portion 3001 to abut against the corresponding central inner surface portion 1041 of the housing 100 in the pre-assembled state of the quick-release clamp. In addition, a first gap 1061 is formed between the two protrusions 350, the central action surface portion 3001 of the sealing ring 300 and the central inner surface portion 1041 of the housing 100, a second gap 1062 is formed between the turning point 3005, the central action surface portion 3001 located outside the protrusions 350 and the inner surface 104 of the housing 100, and the side action surface portion 3006 of the sealing ring 300 and the first inner surface portion 1042 of the housing 100 are parallel to each other, so that the side action surface portion 3006 of the sealing ring 300 can abut against the first inner surface portion 1042 of the housing 100.

[0148] When the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipe element 400 is slightly larger, because the base portion 310 of the sealing ring 300 has a smaller inner diameter than that of a conventional sealing ring, and the gaps 1061 and 1062 formed between the central action surface portion 3001 and the two side action surface portions 3006 of the sealing ring 300 provide space for the sealing ring 300, thereby ensuring that the first pipe element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the fastening action of the fastener 210 in the connecting element 200. The sealing ring 300 will not be partially squeezed out of the housing 100 due to insufficient space in the housing 100.

[0149] In addition, the two protrusions 350 abutting against the inner surface 104 of the housing 100 are symmetrically arranged, so that when the insertion end 401 of the first pipe element 400 is inserted into one side of the housing 100, the protrusion 350 located on the opposite side abuts against the inner surface 104 of the housing 100 to prevent the displacement of the sealing ring 300, thereby preventing the displacement of the thrust portion 320.

[0150] like Figures 14 to 16 The quick-release clamp according to the third preferred embodiment of the present invention is shown, which includes two or more housings 100 , two or more connecting elements 200 preassembled on the housings 100 , and a sealing ring 300 preassembled in the housings 100 .

[0151] Correspondingly, the sealing ring 300 includes a base portion 310, a thrust portion 320, and two pressing end portions 330. The base portion 310 is an annular base 310. In this embodiment of the present invention, the sealing ring 300 is formed with the base portion 310 and the two pressing end portions 330 to form an outer action surface 3000 for abutting against the inner surface 104 of the housing 100. An adaptive sealing structure 340 is formed on the action surface 3000 to enable the sealing ring 300 to adapt to the diameter variation of the pipeline element 400 and prevent the eccentricity of the thrust portion 320.

[0152] More specifically, the outer active surface 3000 of the sealing ring 300 includes a central active surface portion 3001 and two side active surface portions 3006 extending integrally from opposite sides of the central active surface portion 3001 , respectively. The two side active surface portions 3006 can each be an inclined surface or an arc surface.

[0153] The inner surface 104 of each housing 100 includes a central inner surface portion 1041, two first inner surface portions 1042 extending obliquely from both sides of the central inner surface portion 1041, and two second inner surface portions 1043 extending from the first inner surface portion 1042, wherein each second inner surface portion 1043 may be a curved surface or an inclined surface, each first inner surface portion 1042 is an inclined surface or an arc surface, and in this embodiment, each first inner surface portion 1042 is an inclined surface, and the angle between the inclined surface and the central inner surface portion 1041 is an obtuse angle. It can be understood that each first inner surface portion 1042 may also be other curved surfaces in other variant embodiments. The central inner surface portion 1041 located in the central position may be a plane, an arc surface, or a plane with a groove, etc.

[0154] In this embodiment, the central action surface portion 3001 and the two side action surface portions 3006 on the outer side of the sealing ring 300 intersect to form two turning points 3005 , and each turning point 3005 abuts against the first inner surface portion 1042 of the corresponding housing 100 .

[0155] The sealing ring 300 further includes one or more protrusions 350 formed in the central area of ​​the central action surface portion 3001, that is, the adaptive sealing structure 340 of this embodiment includes a protrusion 350 formed in the central action surface portion 3001. The protrusion 350 can be a hemispherical body, a conical boss, a cylindrical boss, a square boss, etc. Fig.16 As shown in FIG. 1 , the protrusion 350 has a gradually decreasing size in a direction toward the central inner surface portion 1041 .

[0156] More specifically, the protrusion 350 is integrally formed protrudingly at the middle area of ​​the central action surface portion 3001 so as to abut against the middle area of ​​the corresponding central inner surface portion 1041 of the housing 100 in the pre-assembled state of the quick-release clamp. In addition, a second gap 1062 is formed around the protrusion 350, the central action surface portion 3001 of the sealing ring 300, the central inner surface portion 1041 of the housing 100, and the turning point 3005, and a third gap 1063 is formed between the side action surface portion 3006 of the sealing ring 300 and the first inner surface portion 1042 of the housing 100.

[0157] Accordingly, in this embodiment of the present invention, when the quick-release clamp is in a pre-assembled state and is not connected to the pipeline element 400, the sealing ring 300 is placed in the inner cavity 102 of the housing 100. At this time, the central protrusion 350 on the outside of the sealing ring 300 abuts against the central area of ​​the central inner surface portion 1041 of the inner surface 104 of the housing 100, and the housing 100 is stretched open to increase the size of the above-mentioned opening 101, so that the corresponding pipeline element 400 can be smoothly inserted. This design not only simplifies the installation process, but also ensures the adaptability of the sealing ring 300, improves the sealing performance of the sealing ring 300, and prevents the eccentricity of the thrust portion 320.

[0158] More specifically, when the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipe element 400 is slightly smaller. Since the central protrusion 350 abuts against the central area of ​​the inner surface 104 of the corresponding housing 100, the pressing end 330 of the sealing ring 300 has a smaller inner diameter than that of a conventional sealing ring, so that it can fit tightly against the insertion end 401 of the pipe element 400 without causing the sealing ring 300 to deviate due to the pipe element 400 abutting against the inner side of the sealing ring 300, that is, to avoid the sealing ring 300 being loosely fitted between the pipe element 400 and the housing 100. The thrust portion 320 is offset by the action of the pipeline element 400, so that the first pipeline element 400 enters the sealing ring 400 too deeply, thereby ensuring that the first pipeline element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipeline element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipeline element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the fastening action of the fastener 210 in the connecting element 200.

[0159] When the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipe element 400 is slightly larger, because the base portion 310 of the sealing ring 300 has a smaller inner diameter than that of a conventional sealing ring, and the gaps 1062 and 1063 formed between the central action surface portion 3001 and the two side action surface portions 3006 of the sealing ring 300 provide space for the sealing ring 300, thereby ensuring that the first pipe element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the tightening action of the fastener 210 in the connecting element 200. The sealing ring 300 will not be partially squeezed out of the housing 100 due to insufficient space in the housing 100.

[0160] like Figures 17 to 19 Shown is a quick-release clamp according to a first variant implementation of the third preferred embodiment of the present invention, which includes two or more shells 100, two or more connecting elements 200 preassembled on the shells 100, and a sealing ring 300 preassembled in the shell 100.

[0161] In this embodiment, the sealing ring 300 further includes a protrusion 350 formed in the central area of ​​the central active surface portion 3001 , that is, the adaptive sealing structure 340 of this embodiment includes the protrusion 350 formed in the central active surface portion 3001 .

[0162] More specifically, the protrusion 350 is integrally formed protrudingly in the middle area of ​​the central action surface portion 3001 so as to abut against the corresponding middle area of ​​the central inner surface portion 1041 of the housing 100 in the pre-assembled state of the quick-release clamp. In addition, a second gap 1062 is formed around the protrusion 350, the central action surface portion 3001 of the sealing ring 300, the central inner surface portion 1041 of the housing 100, and the turning point 3005, while the side action surface portion 3006 of the sealing ring 300 and the first inner surface portion 1042 of the housing 100 are inclined surfaces and are arranged parallel to each other, so that when the quick-release clamp is in the pre-assembled state, the side action surface portion 3006 of the sealing ring 300 and the first inner surface portion 1042 of the housing 100 abut against each other.

[0163] like Figure 20 to Figure 22 Shown is a quick-release clamp according to a second variant implementation of the third preferred embodiment of the present invention, which includes two or more shells 100, two or more connecting elements 200 preassembled on the shells 100, and a sealing ring 300 preassembled in the shell 100.

[0164] In this embodiment, the sealing ring 300 further includes a protrusion 350 formed in the central area of ​​the central active surface portion 3001 , that is, the adaptive sealing structure 340 of this embodiment includes the protrusion 350 formed in the central active surface portion 3001 .

[0165] More specifically, this protrusion 350 is integrally protrudingly formed at a middle region of the central action surface portion 3001 to abut against a corresponding middle region of the central inner surface portion 1041 of the housing 100 in a pre-assembled state of the quick-release clamp.

[0166] In this embodiment, the active surface 3000 on the outer side of the sealing ring 300 includes a central active surface portion 3001, two first active surface portions 3002 extending outwardly from both sides of the central active surface portion 3001, and two second active surface portions 3003 extending from the first active surface portions 3002, wherein the angle between the two first active surface portions 3002 and the central active surface portion 3001 is an obtuse angle, and the two second active surface portions 3003 extend inwardly from the first active surface portion 3002, and the angle between the two second active surface portions 3003 and the corresponding first active surface portion 3002 can be an obtuse angle, a right angle or an acute angle.

[0167] The first action surface portion 3002 extends obliquely from the central action surface portion 3001 in a direction away from the thrust portion 320, and the second action surface portion 3003 extends obliquely or vertically from the corresponding first action surface portion 3002 in a direction close to the thrust portion 320. In this embodiment, each first action surface portion 3002 and each second action surface portion 3003 are illustrated as having a planar structure.

[0168] In this embodiment, a second gap 1062 is formed around the protrusion 350, the central action surface portion 3001 of the sealing ring 300, the central inner surface portion 1041 of the housing 100, and the first inner surface portion 1042, and the first action surface portion 3002 of the sealing ring 300 and the first inner surface portion 1042 of the housing 100 are inclined surfaces and are arranged parallel to each other, so that when the quick-release clamp is in a pre-assembled state, the first action surface portion 3002 of the sealing ring 300 and the first inner surface portion 1042 of the housing 100 abut against each other, and the second action surface portion 3003 extends from the first action surface portion 3002 in a turning manner, so as not to abut against the first inner surface portion 1042. The turning point 3004 formed by the intersection of the first action surface portion 3002 and the corresponding second action surface portion 3003 can abut against the first inner surface portion 1042 of the housing 100 or the turning area between the first inner surface portion 1042 and the second inner surface portion 1043.

[0169] like Figure 23 to Figure 25 Shown is a quick-release clamp according to a fourth preferred embodiment of the present invention, which includes two or more housings 100 , two or more connecting elements 200 preassembled on the housings 100 , and a sealing ring 300 preassembled in the housings 100 .

[0170] The sealing ring 300 includes a base portion 310, a thrust portion 320, and two pressing end portions 330. The base portion 310 is an annular base 310. In this embodiment of the present invention, the sealing ring 300 is formed with the base portion 310 and the two pressing end portions 330 to form an outer action surface 3000 for abutting against the inner surface 104 of the housing 100. An adaptive sealing structure 340 is formed on the action surface 3000 to enable the sealing ring 300 to adapt to the diameter variation of the pipeline element 400 and prevent the eccentricity of the thrust portion 320.

[0171] More specifically, the outer active surface 3000 of the sealing ring 300 includes a central active surface portion 3001 and two side active surface portions 3006 extending integrally from opposite sides of the central active surface portion 3001 , respectively. The two side active surface portions 3006 can each be an inclined surface or an arc surface.

[0172] The inner surface 104 of each housing 100 includes a central inner surface portion 1041, two first inner surface portions 1042 extending obliquely from both sides of the central inner surface portion 1041, and two second inner surface portions 1043 extending from the first inner surface portion 1042, wherein each second inner surface portion 1043 may be a curved surface or an inclined surface, each first inner surface portion 1042 is an inclined surface or an arc surface, and in this embodiment, each first inner surface portion 1042 is an inclined surface, and the angle between the inclined surface and the central inner surface portion 1041 is an obtuse angle. It can be understood that each first inner surface portion 1042 may also be other curved surfaces in other variant embodiments. The central inner surface portion 1041 located in the central position may be a plane, an arc surface, or a plane with a groove, etc.

[0173] In this embodiment, the sealing ring 300 further includes one or more protrusions 360 respectively formed on the two side action surface portions 3006, that is, the adaptive sealing structure 340 of this embodiment includes the protrusions 360 formed on the side action surface portions 3006. The protrusions 360 can be structures such as hemispherical bodies, conical bosses, cylindrical bosses, and square bosses. Fig.25 As shown in FIG. 1 , the protrusion 350 has a gradually decreasing size along the direction toward the first inner surface portion 1042 .

[0174] More specifically, each protrusion 360 is formed integrally and protrudingly at the central area of ​​the side action surface portion 3006, that is, the opposite sides of each protrusion 360 are the inclined surface portions of the side action surface portion 3006, so as to abut against the corresponding first inner surface portion 1042 of the housing 100 in the pre-assembled state of the quick-release clamp. In addition, two fourth gaps 1064 are formed on both sides of each protrusion 360, between the side action surface portion 3006 of the sealing ring 300 and the first inner surface portion 1042 of the housing 100.

[0175] In this embodiment of the present invention, when the quick-release clamp is in a pre-assembled state and is not connected to the pipeline component 400, the sealing ring 300 is placed in the inner cavity 102 of the housing 100. At this time, the two protrusions 360 protruding from the side action surface portion 3006 on the outside of the sealing ring 300 abut against the first inner surface portion 1042 of the inner surface 104 of the housing 100, and the housing 100 is stretched open to increase the size of the above-mentioned opening 101, so that the corresponding pipeline component 400 can be smoothly inserted. This design not only simplifies the installation process, but also ensures the adaptability of the sealing ring 300, improves the sealing performance of the sealing ring 300, and prevents the eccentricity of the thrust portion 320.

[0176] More specifically, when the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipe element 400 is slightly smaller. Since the protrusion 360 abuts against the first inner surface portion 1042 of the inner surface 104 of the corresponding housing 100, the pressing end portion 330 of the sealing ring 300 has a smaller inner diameter than that of a conventional sealing ring, so that it can fit closely to the insertion end 401 of the pipe element 400 without causing the sealing ring 300 to deviate due to the pipe element 400 abutting against the inner side of the sealing ring 300, that is, to avoid the sealing ring 300 from being loosely fitted between the pipe element 400 and the housing 100. Sometimes, the pipe element 400 is offset and the thrust portion 320 is eccentric, so that the first pipe element 400 enters the sealing ring 400 too deeply, thereby ensuring that the first pipe element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the fastening action of the fastener 210 in the connecting element 200.

[0177] When the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipe element 400 is slightly larger, the base portion 310 of the sealing ring 300 has a smaller inner diameter than the conventional sealing ring, and the fourth gap 1064 formed between the side action surface portion 3006 of the sealing ring 300 and the inclined first inner surface portion 1042 of the housing 100 provides space for the sealing ring 300, thereby ensuring that the first pipe element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the tightening action of the fastener 210 in the connecting element 200. The sealing ring 300 will not be partially squeezed out of the housing 100 due to insufficient space in the housing 100.

[0178] In addition, the two protrusions 360 abutting against the first inner surface portion 1042 of the inner surface 104 of the housing 100 are symmetrically arranged, so that when the insertion end 401 of the first pipe element 400 is inserted into one side of the housing 100, the protrusion 360 located on the opposite side abuts against the first inner surface portion 1042 of the inner surface 104 of the housing 100 to prevent displacement of the sealing ring 300, thereby preventing deviation of the thrust portion 320.

[0179] like Figure 26 to Figure 28 Shown is a modified implementation of a quick-release clamp according to a fourth preferred embodiment of the present invention, which includes two or more shells 100, two or more connecting elements 200 preassembled on the shells 100, and a sealing ring 300 preassembled in the shell 100.

[0180] The outer action surface 3000 of the sealing ring 300 includes a central action surface portion 3001 and two side action surface portions 3006 extending integrally from opposite sides of the central action surface portion 3001 . The two side action surface portions 3006 can be inclined surfaces or arc surfaces.

[0181] In this embodiment, the sealing ring 300 further includes one or more protrusions 360 respectively formed on the two side action surface portions 3006, that is, the adaptive sealing structure 340 of this embodiment includes the protrusions 360 formed on the side action surface portions 3006. In this embodiment, the protrusions 360 extend in a direction parallel to the central inner surface portion 1041 of the corresponding housing 100 and abut against the inclined first inner surface portion 1042 of the housing 100, so that when the quick-release clamp is in a pre-assembled state, the housing 100 is supported by the protrusions 360 on both sides.

[0182] like Fig.28 As shown in the figure, the protrusion 360 includes an abutment surface 361, which contacts the first inner surface portion 1042 implemented as a slope in parallel, and two fourth gaps 1064 are respectively formed on both sides of the protrusion 360, between the side action surface portion 3006 of the sealing ring 300 and the first inner surface portion 1042 of the housing 100.

[0183] like Figure 29 to Figure 31 Shown is a quick-release clamp according to a fifth preferred embodiment of the present invention, which includes two or more housings 100 , two or more connecting elements 200 preassembled on the housings 100 , and a sealing ring 300 preassembled in the housings 100 .

[0184] The sealing ring 300 includes a base portion 310, a thrust portion 320, and two pressing end portions 330. The base portion 310 is an annular base 310. In this embodiment of the present invention, the sealing ring 300 is formed with the base portion 310 and the two pressing end portions 330 to form an outer action surface 3000, which is used to abut against the inner surface 104 of the shell 100. An adaptive sealing structure 107 is formed on the inner surface 104 of the shell 100 to enable the sealing ring 300 to adapt to the diameter change of the pipeline element 400 and prevent the eccentricity of the thrust portion 320.

[0185] More specifically, the outer active surface 3000 of the sealing ring 300 includes a central active surface portion 3001 and two side active surface portions 3006 extending integrally from opposite sides of the central active surface portion 3001 , respectively. The two side active surface portions 3006 can each be an inclined surface or an arc surface.

[0186] The inner surface 104 of each shell 100 includes a central inner surface portion 1041, two first inner surface portions 1042 extending obliquely from both sides of the central inner surface portion 1041, and two second inner surface portions 1043 extending from the first inner surface portions 1042, wherein each second inner surface portion 1043 may be a curved surface or an inclined surface, and each first inner surface portion 1042 is an inclined surface or an arc surface, and in this embodiment, each first inner surface portion 1042 is an inclined surface and the angle between it and the central inner surface portion 1041 is an obtuse angle.

[0187] In this embodiment, the adaptive sealing structure 107 on the inner surface 104 of the housing 100 includes a protrusion 1071 integrally formed on the central inner surface portion 1041, and two grooves 1072 are respectively formed on both sides of the protrusion 1071. The central action surface portion 3001 of the sealing ring 300 is correspondingly in contact with the protrusion 1071 protruding on the central inner surface portion 1041 of the housing 100. In this way, when the quick-release clamp is in a pre-assembled state, except for the portion where the central action surface portion 3001 of the sealing ring 300 contacts the protrusion 1071 protruding on the central inner surface portion 1041 of the housing 100, the rest of the sealing ring 300 is spaced apart from the inner surface 104 of the housing 100.

[0188] On the other side of the shell 100 opposite to the raised portion 1071, the shell 100 forms an inner groove 1073 on its outer surface. That is, while the inner groove 1073 is formed on the outer surface by burying the protrusion of the mold into the outer surface of the shell 100, a corresponding raised portion 1071 is formed on the inner side of the shell 100, thereby facilitating the formation of the adaptive sealing structure 107 of the shell.

[0189] In this embodiment of the present invention, when the quick-release clamp is in a pre-assembled state and is not connected to the pipeline element 400, the sealing ring 300 is placed in the inner cavity 102 of the housing 100. At this time, the central inner surface portion 3001 on the outer side of the sealing ring 300 abuts against the protrusion 1071 on the central inner surface portion of the inner surface 104 of the housing 100, and the housing 100 is stretched open to increase the size of the above-mentioned opening 101, so that the corresponding pipeline element 400 can be smoothly inserted. This design not only simplifies the installation process, but also ensures the adaptability of the sealing ring 300, improves the sealing performance of the sealing ring 300, and prevents the eccentricity of the thrust portion 320.

[0190] More specifically, when the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipe element 400 is slightly smaller. Since the protrusion 1071 of the housing 100 abuts against the central action surface portion 3001 of the corresponding outer action surface 3000 of the sealing ring 300, the pressing end portion 330 of the sealing ring 300 has a smaller inner diameter than that of a conventional sealing ring, so that it can fit closely to the insertion end 401 of the pipe element 400 without causing the sealing ring 300 to deviate due to the pipe element 400 abutting against the inner side of the sealing ring 300, that is, to prevent the sealing ring 300 from being loosely fitted to the pipe element 400. The first pipe element 400 is inserted between the housing 100 and is offset by the action of the pipe element 400, so that the thrust portion 320 is eccentric, and the first pipe element 400 enters the sealing ring 400 too deeply, thereby ensuring that the first pipe element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the fastening action of the fastener 210 in the connecting element 200.

[0191] When the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipe element 400 is slightly larger, because the base portion 310 of the sealing ring 300 has a smaller inner diameter than the traditional sealing ring, and the grooves 1072 on both sides of the protrusion 1071 of the housing 100 provide space for the sealing ring 300, thereby ensuring that the first pipe element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the fastening action of the fastener 210 in the connecting element 200. The sealing ring 300 will not be partially squeezed out of the housing 100 due to insufficient space in the housing 100.

[0192] like Figure 32 to Figure 34 Shown is a quick-release clamp according to a sixth preferred embodiment of the present invention, which includes two or more housings 100 , two or more connecting elements 200 preassembled on the housings 100 , and a sealing ring 300 preassembled in the housings 100 .

[0193] The sealing ring 300 includes a base portion 310, a thrust portion 320, and two pressing end portions 330. The base portion 310 is an annular base 310. In this embodiment of the present invention, the sealing ring 300 is formed with the base portion 310 and the two pressing end portions 330 to form an outer acting surface 3000 for abutting against the inner surface 104 of the housing 100. An adaptive sealing structure 340 is formed on the inner surface 104 of the housing 100 and the outer acting surface 3000 of the sealing ring 300 to enable the sealing ring 300 to adapt to the diameter variation of the pipeline element 400 and prevent the eccentricity of the thrust portion 320.

[0194] More specifically, the outer action surface 3000 of the sealing ring 300 is implemented as an arcuate action surface 3007. The inner surface 104 of each housing 100 includes an arcuate inner surface portion 1045 located in the center, and two extended inner surface portions 1046 extending in a curved line from both sides of the arcuate inner surface portion 1045. In this embodiment, the arcuate inner surface portion 1045 forms a receiving groove 1047 on the inner surface 104 of the housing 100, and the extended inner surface portion 1046 extends in a curved line and forms a notch 1048 on the inner surface 104 of the housing 100.

[0195] In this embodiment, the adaptive sealing structure 340 correspondingly includes an arcuate action surface 3007 of the sealing ring 300 and an arcuate inner surface portion 1045 of the inner surface 104 of the housing 100. In this embodiment, the arc length of the arcuate action surface 3007 of the sealing ring 300 is less than or equal to the arcuate inner surface portion 1045 of the inner surface 104 of the housing 100, and the radius of the arcuate action surface 3007 of the sealing ring 300 is greater than the arcuate inner surface portion 1045 of the inner surface 104 of the housing 100, so that when the quick-release clamp is in a pre-assembled state, a portion of the arcuate action surface 3007 of the sealing ring 300 is located in the receiving groove 1047, and the arcuate action surface 3007 of the sealing ring 300 and the arcuate inner surface portion 1045 of the inner surface 104 of the housing 100 form a spacing gap 108, and the remaining portion of the arcuate action surface 3007 of the sealing ring 300 is outside the receiving groove 1047.

[0196] In this embodiment of the present invention, when the quick-release clamp is in a pre-assembled state and not connected to the pipeline element 400, the sealing ring 300 is placed in the inner cavity 102 of the housing 100. At this time, two contact points 3008 on the arc length of the arc-shaped action surface 3007 on the outside of the sealing ring 300 abut against the arc-shaped inner surface 1045 of the inner surface 104 of the housing 100, and the two housings 100 are stretched apart to increase the size of the above-mentioned opening 101, so that the corresponding pipeline element 400 can be smoothly inserted. This design not only simplifies the installation process, but also ensures the adaptability of the sealing ring 300, improves the sealing performance of the sealing ring 300, and prevents the eccentricity of the thrust portion 320.

[0197] More specifically, when the first pipeline element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipeline element 400 is slightly smaller. Since both sides of the arcuate action surface 3007 of the sealing ring 300 extend to the receiving groove 1047 formed by the arcuate action surface 1045 of the inner surface 104 of the housing 100, the sealing ring 300 in this embodiment of the present invention is slightly offset inward as a whole relative to the conventional sealing ring, so that the pressing end 330 of the sealing ring 300 has a smaller inner diameter relative to the conventional sealing ring, so that it can be closely fitted to the insertion end 401 of the pipeline element 400 without causing the sealing ring 300 to be offset due to the abutment of the pipeline element 400 against the inner side of the sealing ring 300. That is to say, it is prevented that the sealing ring 300 is loosely fitted between the pipe element 400 and the housing 100 and is offset by the action of the pipe element 400, so that the thrust portion 320 is eccentric and the first pipe element 400 enters the sealing ring 400 too deeply, thereby ensuring that the first pipe element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the fastening action of the fastener 210 in the connecting element 200.

[0198] When the first pipe element 400 is inserted into the housing 100 and the sealing ring 300, the gap 108 formed by the arcuate action surface 3007 of the sealing ring 300 and the arcuate inner surface portion 1045 of the inner surface 104 of the housing 100 provides space, and the first pipe element 400 can reach the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the fastening action of the fastener in the connecting element 200. The sealing ring 300 will not be partially squeezed out of the housing 100 due to insufficient space in the housing 100.

[0199] In this embodiment, when the insertion ends 401 of the two pipe elements 400 are inserted into the housing 100 and the sealing ring 300 of the quick-release clamp, by operating at least one fastener 210 in the connecting element 200, the size of the openings 101 of the two housings 100 is forced to decrease, the engagement keys 103 of the two housings 100 extend into the engagement grooves 402 of the corresponding pipe elements 400, and the inner surfaces 104 of the housings are respectively pressed against the outer acting surfaces 3000 of the sealing ring 300, so that the arcuate acting surface 3007 of the sealing ring 300 enters the receiving groove 1047 formed by the arcuate inner surface portion 1045 of the inner surface 104 of the housing 100, so that the sealing ring 300 is tightly clamped between the insertion end 401 of the pipe element 400 and the inner surface 104 of the housing 100 to achieve sealing of the pipe element 400.

[0200] like Figure 35 to Figure 37 Shown is a quick-release clamp according to a seventh preferred embodiment of the present invention, which includes two or more housings 100 , two or more connecting elements 200 preassembled on the housings 100 , and a sealing ring 300 preassembled in the housings 100 .

[0201] The sealing ring 300 includes a base portion 310, a thrust portion 320, and two pressing end portions 330. The base portion 310 is an annular base 310. In this embodiment of the present invention, the sealing ring 300 is formed with the base portion 310 and the two pressing end portions 330 to form an outer action surface 3000 for abutting against the inner surface 104 of the housing 100. An adaptive sealing structure 340 is formed on the outer action surface 3000 of the sealing ring 300 to enable the sealing ring 300 to adapt to the diameter variation of the pipeline element 400 and prevent the eccentricity of the thrust portion 320.

[0202] More specifically, the outer active surface 3000 of the sealing ring 300 includes a central active surface portion 3001, two side active surface portions 3006 extending integrally from opposite sides of the central active surface portion 3001, and two pressing active surface portions 3009 extending from the two side active surface portions 3006 toward the center direction of the sealing ring 300, respectively. The two side active surface portions 3006 can each be an inclined surface or an arc surface, and the two pressing active surface portions 3009 are respectively suitable for facing the pipeline element 400 and at least partially abutting against the outer surface of the pipeline element 400 when the pipeline element 400 is installed.

[0203] Each pressing surface portion 3009 includes at least two parts, namely Fig.37 As shown in , each pressure surface portion 3009 includes a first pressure surface portion 30091 and a second pressure surface portion 30092 extending integrally from the first pressure surface portion 30091. The first pressure surface portion 30091 and the second pressure surface portion 30092 can each be an inclined surface or an arc surface.

[0204] In this embodiment, the first section of the pressing surface portion 30091 and the second section of the pressing surface portion 30092 are each inclined surfaces, and the inclination angles are different. More specifically, the first section of the pressing surface portion 30091 is integrally extended to the corresponding side surface portion 3006 and has a first inclination angle α, and the second section of the pressing surface portion 30092 is integrally extended to the first section of the pressing surface portion 30091 and is close to the central axis of the sealing ring 300, and has a second inclination angle β, wherein the second inclination angle β is greater than the first inclination angle α.

[0205] The first inclination angle α and the second inclination angle β are respectively the angles formed by the first section of the pressing surface portion 30091 and the second section of the pressing surface portion 30092 and a baseline, and the baseline is parallel to the central axis of the sealing ring 300. Fig.37 In the example, the baseline can be a horizontal line.

[0206] Preferably, in this embodiment, the first inclination angle α is in the range of 0°-30°, the second inclination angle β is in the range of 20°-60°, and β>α is satisfied at the same time.

[0207] The inner surface 104 of each housing 100 includes a central inner surface portion 1041, two first inner surface portions 1042 extending obliquely from both sides of the central inner surface portion 1041, and two second inner surface portions 1043 extending from the first inner surface portion 1042, wherein each second inner surface portion 1043 may be a curved surface or an inclined surface, each first inner surface portion 1042 is an inclined surface or an arc surface, and in this embodiment, each first inner surface portion 1042 is an inclined surface, and the angle between the inclined surface and the central inner surface portion 1041 is an obtuse angle. It can be understood that each first inner surface portion 1042 may also be other curved surfaces in other modified embodiments. The central inner surface portion 1041 located in the central position is further formed with a central groove 1049, thereby providing an increased accommodation space for the sealing ring 300.

[0208] In this embodiment of the present invention, when the quick-release clamp is in a pre-assembled state and is not connected to the pipeline component 400, the sealing ring 300 is placed in the inner cavity 102 of the housing 100. At this time, the side action surface portion 3006 on the outer side of the sealing ring 300 abuts against the first inner surface portion 1042 of the inner surface 104 of the housing 100 to open the housing 100 so that the corresponding pipeline component 400 can be smoothly inserted.

[0209] When the first pipeline element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipeline element 400 is slightly smaller. Since the second section of the pressing surface portion 30092 with a larger inclination angle can contact the outer surface of the first pipeline element 400, it is prevented that the sealing ring 300 is loosely fitted between the pipeline element 400 and the housing 100 and is offset by the action of the pipeline element 400, so that the thrust portion 320 is eccentric and the first pipeline element 400 enters the sealing ring 400 too deeply, thereby ensuring that the first pipeline element 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipeline element 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipeline element 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the fastening action of the fastener 210 in the connecting element 200.

[0210] When the first pipeline element 400 is inserted into the housing 100 and the sealing ring 300, the diameter of the first pipeline element 400 is slightly larger, and the central groove 1049 at the central inner surface portion 1041 of the housing 100 located at the central position provides an increased accommodation space for the sealing ring 300, and each first section of the pressing surface portion 30091 of the pressing end portion 330 of the sealing ring 300 extends at a relatively gentle inclination angle, so that the end of the second section of the pressing surface portion 30092 is slightly farther away from the center of the sealing ring than the traditional sealing ring, so as to avoid the sealing ring 300 from being pressed between the housing 100 and the pipeline during the assembly process. The components 400 are over-compressed, thereby ensuring that the first pipe component 400 reaches the expected position where its insertion end 401 abuts against the thrust portion 320, thereby further ensuring that the insertion end 401 of the second pipe component 400 smoothly reaches the position abutting against the other side of the thrust portion 320, so that the engagement groove 402 of the second pipe component 400 can be aligned with the engagement key 103 of the corresponding housing 100 and the final assembly is completed through the fastening action of the fastener 210 in the connecting component 200, and the sealing ring 300 will not be partially squeezed out of the housing 100 due to insufficient space in the housing 100.

These decompositions and / or recombinations should be considered to be included in the inventive concept of the present application.
