Description

Technical Field

[0001] The utility model relates to the technical field of pipeline and cable connection, in particular to a quick-release clamp. Background Art

[0002] Clamps are crucial components for civil aircraft system installations, maintaining the position and load transfer of aircraft pipes and cables (hereinafter referred to as pipes). Currently, aircraft carry numerous pipes and cables for energy and fluid transfer, and these pipes are typically secured to the aircraft structure or brackets using clamps.

[0003] Commonly used clamps on aircraft include P-type clamps and saddle-type clamps. These clamps consist of two clamp bodies, and the pipeline is usually fixed and secured by bolts passing through the through holes on the clamp bodies and locking nuts. In production practice, especially during flight tests and operations, it is often necessary to frequently disassemble and assemble the clamps in order to measure or organize the pipelines. However, since these clamps are installed and fixed using threads, their assembly and disassembly requires the use of tools such as wrenches or screwdrivers. Therefore, the required assembly and disassembly construction space is large, and the time spent on assembly and disassembly is also relatively long. This means that the labor cost of disassembling the clamps to release or clamp the pipeline is high, and production efficiency is low. At the same time, in certain locations on the aircraft, the fasteners used to install the clamps even need to be wet-installed and sealed with sealant, which results in more time being spent on disassembling and assembling the clamps.

[0004] Therefore, in order to improve production efficiency, an improved quick-release clamp that can be quickly installed or disassembled is needed. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the existing clamps for disassembling and assembling pipelines take too long and are too inefficient, and a new quick-release clamp is proposed.

[0006] The utility model solves the above technical problems through the following technical solutions:

[0007] Specifically, the utility model provides a quick-release clamp, which includes: a fixed half, which can be detachably mounted on an aircraft body structure and has a first surface that can fit the surface of an object to be installed, wherein first joint portions are respectively formed on the circumferential end walls of the first surface; a movable half, which has a second surface that can fit the surface of an object to be installed, wherein second joint portions are respectively formed on the circumferential end walls of the second surface; and a pin member, wherein the movable half is configured to be formed as a whole with the fixed half by aligning the first joint portion with the second joint portion and passing the pin member through the pin holes on the first joint portion and the second joint portion, so that the first surface and the second surface are opposite to each other, thereby forming a space therebetween that can receive the object to be installed.

[0008] The utility model provides a quick-release clamp that can be used to secure an object without requiring a threaded structure. The quick-release clamp is divided into two halves that can be connected and locked using only a pin, thereby securing the pipeline and ultimately securing it. Furthermore, by securing the pipeline with the quick-release clamp, maintenance personnel can remove and install the pipeline without the use of tools and can operate with one hand, significantly reducing maintenance time and space requirements, thereby significantly improving maintenance efficiency.

[0009] According to one embodiment of the present invention, a mounting seat extending horizontally is formed at the bottom of the fixed half, and the quick-release clamp is configured to be removably mounted to the aircraft body structure via the mounting seat. The mounting seat allows the fixed half to be first mounted to the aircraft body structure, facilitating positioning of an object to be mounted on the first surface of the fixed half, thereby enabling rapid positioning of the object to be mounted on the quick-release clamp. Furthermore, after the fixed half and the movable half are fixedly connected, the quick-release clamp is mounted to the aircraft body structure using a connection method such as fasteners or welding, thereby securing the object to be mounted in the quick-release clamp at a desired position on the aircraft body structure.

[0010] According to one embodiment of the present invention, the first joint portion is configured as a single-ear joint and is formed with a pin hole extending in a longitudinal direction parallel to the quick-release clamp, and the second joint portion is configured as a double-ear joint and is formed with a pin hole extending in a longitudinal direction parallel to the quick-release clamp. The single-ear joint can be positioned between the two ears of the double-ear joint so that the pin hole of the single-ear joint is aligned with the pin hole of the double-ear joint. The connection and fixation of the fixed half and the movable half are achieved through the alignment of the pin holes in the ear joints and the cooperation between the pin holes and the pin member.

[0011] According to one embodiment of the present invention, the pin hole on the first joint part on at least one circumferential end wall of the fixed half is configured as a hole with a circular cross-section, the pin hole on the second joint part corresponding to the position of the first joint part having the circular pin hole is configured as a hole with a circular cross-section, and the pin member is configured to have a circular cross-section, so that after the pin member passes through the circular pin hole on the first joint part and the corresponding circular pin hole on the second joint part, the movable half can rotate relative to the fixed half.

[0012] According to one embodiment of the present invention, the pin member is configured such that after passing through the circular pin holes on the first joint part and the second joint part, both ends of the pin member are processed so that the sizes of both ends are larger than the sizes of the circular pin holes on the first joint part and the second joint part.

[0013] The pin holes in the aligned joints are cylindrical, and the pin members are also cylindrical. After passing through the pin holes, the pin members mate with the joints to form a revolving pair, thereby achieving a rotatable connection between the movable and fixed half. In other words, the movable half can rotate relative to the fixed half about the pin member to open and close the quick-release clamp. Furthermore, after the pin member passes through the pin holes, the dimensions of both ends of the pin member are processed to be larger than the pin hole, thereby preventing the pin member from slipping out of the cylindrical pin hole during use.

[0014] According to one embodiment of the present invention, the pin hole on the first joint portion on one circumferential end wall of the fixed half is configured as a hole with a square cross section, and the pin hole on the second joint portion corresponding to the position of the first joint portion having the square pin hole is configured as a hole with a square cross section, and the pin member includes a first pin member and a second pin member, the first pin member having a circular cross section, and the second pin member having a square cross section and configured to pass through the square pin hole on the first joint portion and the corresponding square pin hole on the second joint portion, thereby fixing the movable half to the fixed half. The cross sections of the pin hole and the second pin member are both set to square so that the two match, thereby enabling the relative fixation of the fixed half and the movable half to be achieved by passing the second pin member through the square pin hole.

[0015] According to one embodiment of the present invention, the second pin member includes a head and a rod portion extending from the head portion, wherein the end portion of the rod portion is formed with an elastic structural feature, which is configured to prevent the second pin member from moving in a direction opposite to the passing direction after allowing the rod portion of the second pin member to pass through the square pin hole on the first joint portion and the corresponding square pin hole on the second joint portion.

[0016] According to a preferred embodiment of the present invention, the elastic structure is characterized by being configured as at least two elastic legs that extend outward from the end portion of the rod and are arranged opposite to each other, with a certain distance between the elastic legs and a small protrusion on the outward surface of the end of the elastic leg. In this way, when the second pin member having the above-mentioned elastic legs passes through the square pin hole on the first joint part and the second joint part, they will move closer to each other under the squeezing action of the square pin hole wall, thereby ensuring that the rod of the pin member can smoothly pass through the square pin hole. After the elastic legs pass through the square pin hole, the two elastic legs rebound to their original position, and the small protrusions protruding outwardly provided thereon can be stuck on the orifice wall of the square pin hole of the first joint part or the second joint part, thereby preventing the second pin member from moving in a direction opposite to the direction of insertion of the second pin member, thereby ensuring that the second pin member passing through the square pin hole can be firmly fixed in the square pin hole and will not accidentally fall out.

[0017] According to an embodiment of the present invention, the size of the head portion is larger than the size of the square pin holes on the first joint portion and the second joint portion.

[0018] According to one embodiment of the present invention, the distance between the head and the small protrusion is equal to or greater than the sum of the lengths of the square pin hole of the first joint portion and the square pin hole of the second joint portion. In other words, the distance between the head and the small protrusion is greater than or at least equal to the sum of the lengths of the first joint portion and the second joint portion along the longitudinal direction through which the second pin member passes. Thus, after the rod portion passes through the square pin hole, the head portion can engage with one end opening of the square pin hole, while the small protrusion can engage with the other end opening of the square pin hole, thereby longitudinally retaining the first and second joint portions between the head portion and the small protrusion on the elastic leg.

[0019] On the basis of conforming to the common sense in this field, the above preferred implementation modes can be arbitrarily combined to obtain the preferred implementation modes of the present utility model.

[0020] The positive and progressive effects of the above-mentioned embodiments of the present invention are:

[0021] 1. The quick-release clamp can be connected and locked using only a pin component, thereby locking the pipeline and ultimately achieving pipeline installation. Moreover, the quick-release clamp locks the pipeline, allowing maintenance personnel to remove and install the pipeline without the use of tools and with one hand, thereby greatly shortening maintenance time and reducing maintenance space requirements, greatly improving maintenance efficiency.

[0022] 2. Design an elastic structural feature on the second pin member. The spacing between the elastic legs in this elastic structural feature provides room for deformation of the elastic legs, ensuring that the rod portion of the second pin member can smoothly pass through the corresponding pin hole. This spacing also prevents the small protrusion from being subjected to excessive pressure when passing through the pin hole, preventing the pin hole wall from damaging the elasticity of the elastic legs. This allows the elastic legs to rebound to their original shape after passing through the pin hole, thereby limiting the reverse movement of the second pin member. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that all other embodiments obtained by ordinary technicians in this field based on the embodiments described in this application without expending creative effort will fall within the scope of protection of this application.

[0033] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms "including" and "having" in the specification and claims of this application and the above-mentioned description of the drawings are open-ended terms. Therefore, "including" and "having" for example, one or more components, means that the device has one or more components, but is not limited to having only these one or more components.

[0034] like Figure 1 As shown, the present invention provides a quick release clamp, which comprises a fixed half 1 that can be detachably mounted on the aircraft body structure, a movable half 2 arranged opposite to the fixed half 1, and pin members 3 and 4 that can connect the fixed half 1 and the movable half 2 into a whole. Figure 1 and 2 As shown, the fixed half 1 includes a first surface S1 capable of conforming to the surface of an object to be mounted (not shown), and first joints 101 and 102 are formed at two end walls 11 and 12 of the wall extending in the circumferential direction of the first surface S1. The movable half 2 includes a second surface S2 capable of conforming to the surface of an object to be mounted, and second joints 201 and 202 are formed at two end walls 21 and 22 of the wall extending in the circumferential direction of the second surface S2.

[0035] The first joints 101 and 102 of the fixed half 1 are formed with pin holes 114 and 115, respectively, extending in the longitudinal direction of the quick-release clamp. The second joints 201 and 202 of the movable half 2 are also formed with pin holes 214 and 215, respectively, extending in the longitudinal direction of the quick-release clamp. When the fixed half 1 and the movable half 2 are placed opposite each other, the first surface S1 and the second surface S2 face each other, forming a space S3 therebetween capable of receiving an object to be mounted. At this time, the first joint parts 101, 102 and the corresponding second joint parts 201, 202 are aligned with each other, and the pin holes 114, 115 of the first joint parts 101, 102 are also aligned with the pin holes 214, 215 of the corresponding second joint parts 201, 202, respectively, so that the pin members 3, 4 are allowed to pass through the pin holes 114, 115 of the first joint parts 101, 102 and the pin holes 214, 215 of the second joint parts 201, 202 that are aligned with each other in sequence, thereby connecting the fixed half 1 and the movable half 2 into a whole, as shown in FIG. Figure 2 shown.

[0036] It should be understood that, in this context, "connected into one piece" refers to the fixed half 1 and the movable half 2 being connected and fixed together to form a complete quick-release clamp component. Furthermore, the objects to be mounted can be, but are not limited to, pipes and cables that need to be fixed to the aircraft structure. Other onboard equipment, components, or devices that need to be fixed to the aircraft structure can also be mounted. Furthermore, space S3 can have various shapes, such as cylindrical or rectangular.

[0037] like Figure 3 and 4 As shown, a mounting seat 103 extending in the horizontal direction is formed at the bottom of the fixed half 1. The quick-release clamp according to the present invention can be detachably mounted on the aircraft body structure via the mounting seat 103 by mechanical means such as fasteners.

[0038] According to one embodiment, the fixed half 1 has a first joint portion 101 or 102 formed on one end wall 11 and the other end wall 12, respectively, of the wall extending in the circumferential direction of the first surface S1 of the fixed half 1. The first joint portions 101 or 102 can be configured as single-ear joints 111 or 112 protruding outward from the end walls 11 or 12 of the fixed half 1. The single-ear joints 111 or 112 can, for example, have a generally cylindrical shape, and pin holes 114 or 115 extending in the longitudinal direction of the quick-release clamp are formed in the middle of the single-ear joints 111 or 112. According to one example, the pin hole 114 of the first joint portion 101 on the one end wall 11 of the fixed half 1 and the pin hole 115 of the first joint portion 102 on the other end wall 12 have the same shape and both have circular cross-sections.

[0039] According to one embodiment, the movable half 2 has a second joint portion 201, 202 formed on one end wall 21 and the other end wall 22 of the wall extending in the circumferential direction of the second surface S2 of the movable half 2. The second joint portion 201, 202 can be configured as a double-ear joint 211, 212 protruding outward from the end walls 21, 22 of the movable half 2. Each of the double-ear joints 211, 212 includes two ears 221, 231, 222, 232 spaced apart and arranged side by side in the longitudinal direction of the quick release clamp, and the longitudinal spacing between the two side-by-side ears 221, 231 or 222, 232 is at least equal to the length of the single-ear joint 111 or 112 of the fixed half 1. In this way, when the fixed half 1 and the movable half 2 are placed opposite to each other, the single ear connector 111 on one side end wall 11 of the fixed half 1 can be inserted between the two side-by-side ear portions 221, 231 on the corresponding side end wall 21 of the movable half 2, and the single ear connector 112 on the other side end wall 12 of the fixed half 1 can be inserted between the two side-by-side ear portions 222, 232 on the other side end wall 22 of the movable half 2.

[0040] Each ear portion 221, 231, 222, 232 of the double-ear connector 211, 212 may, for example, have a generally cylindrical shape. A pin hole 214 or 215 extending in the longitudinal direction of the quick-release clamp is formed in the center of each ear portion 221, 231 or 222, 232. According to a preferred embodiment, the pin hole 214 of the second connector portion 201 on the one end wall 21 of the movable half 2 and the pin hole 215 of the second connector portion 202 on the other end wall 22 have the same shape and both have circular cross-sections.

[0041] In this case, the pin members 3 and 4 are configured as cylindrical pin members, and both ends 301 of the cylindrical pin members may be subjected to machining processing such as upsetting after passing through the single-ear joints 111 and 112 and the double-ear joints 211 and 212, so that the diameters of the both ends 301 are larger than the diameters of the pin holes 114 and 115 of the single-ear joints 111 and 112 and the pin holes 214 and 215 of the double-ear joints 211 and 212.

[0042] Thus, when using the quick-release clamp according to the present invention to install pipes and cables to be secured to an aircraft fuselage structure, the fixed half 1 and the movable half 2 are positioned relative to each other, with the first surface S1 and the second surface S2 facing each other, thereby forming a space S3 therebetween capable of receiving the pipes and cables to be installed. Subsequently, a cylindrical pin member 3 is sequentially inserted through the circular pin holes of the single-ear joint 111 and the double-ear joint 211 located on the same side of the movable half 2 and the fixed half 1, and a cylindrical pin member 4 is sequentially inserted through the circular pin holes of the single-ear joint 112 and the double-ear joint 212 located on the other side of the movable half 2 and the fixed half 1. Next, the ends of the pin members 3 and 4 that emerge from the circular pin hole of the double-ear joint 211 are processed so that the diameters of the two ends 301 are larger than the diameters of the pin holes 214 and 215 of the double-ear joints 211 and 212, thereby securely connecting the fixed half 1 and the movable half 2 into a single, integral unit.

[0043] According to another embodiment, Figure 4 As shown, the first connector portion 101 on one end wall 11 of the fixed half 1 can be configured as an outwardly protruding single-ear connector 111. This single-ear connector 111 can, for example, have a generally cylindrical shape, wherein a circular pin hole 114 extending in the longitudinal direction of the quick-release clamp is formed. The first connector portion 102 on the other end wall 12 of the fixed half 1 can be configured as an outwardly protruding single-ear connector 112. This single-ear connector 112 can, for example, have a generally prismatic shape, wherein a square pin hole 115 extending in the longitudinal direction of the quick-release clamp is formed.

[0044] Correspondingly, if Figure 5 As shown, the second joint portion 201 on one end wall 21 of the movable half 2 can be configured as an outwardly protruding double-ear joint 211. Each ear portion 221, 231 of the double-ear joint 211 can have, for example, a generally cylindrical shape, wherein the pin holes 214 formed in the ears 221, 231 and extending in the longitudinal direction of the quick-release clamp are circular pin holes. The second joint portion 202 on the other end wall 22 of the movable half 2 can also be configured as an outwardly protruding double-ear joint 212. However, each ear portion 222, 232 of the double-ear joint 212 can have, for example, a generally prismatic shape, and the pin holes 215 formed in the ears 222, 232 and extending in the longitudinal direction of the quick-release clamp are square pin holes.

[0045] In this case, if Figure 6As shown, the pin member 3 is constructed as a cylindrical pin member with a circular cross-section, and the two ends 301 of the cylindrical pin member can be processed by machining such as upsetting after passing through the pin holes 114 and 214 on the single-ear joint 111 and the double-ear joint 211 so that the diameters of the two ends 301 are larger than the diameters of the pin holes 114 and 214 of the double-ear joint 211.

[0046] At the same time, if Figure 7 As shown, the pin member 4 is constructed as a square pin member, having a square cross-section that matches the dimensions of the square pin holes in the first and second joint parts. It can pass through the square pin holes 115 and 215 in the single-ear joint 112 and double-ear joint 212, respectively, to securely connect one side of the first joint part to the second joint part. Specifically, the pin member 4 includes a head 401 and a shaft 402 extending from the head 401 along the longitudinal direction of the pin member 4. Both the head 401 and the shaft 402 have a square cross-section. The head 401 is larger than the square pin holes in the first and second joint parts. The distal end of the shaft 402 is formed with an elastic feature 403. This elastic feature 403 can be configured as two elastic legs 404 arranged opposite each other, extending from the distal end of the shaft 402, with a certain distance between the two elastic legs 404. Furthermore, a small protrusion 405 is provided on the outward-facing surface of each elastic leg 404. In this way, when the pin member 4 passes through the square pin holes on the first joint part and the second joint part, the two elastic legs 404 will move closer to each other under the squeezing effect of the square pin hole walls, thereby ensuring that the rod portion 402 of the pin member 4 can smoothly pass through the square pin holes. After the elastic legs 404 pass through the square pin holes, the two elastic legs 404 rebound to their original positions, and the small protrusions 405 protruding outwards on them can be caught on the hole walls of the square pin holes of the first joint part or the second joint part, thereby preventing the pin member 4 from moving in the direction opposite to the direction of insertion of the pin member 4, thereby ensuring that the pin member 4 passing through the square pin holes can be firmly fixed in the square pin holes and will not accidentally fall out.

[0047] It should be noted that the number of elastic legs 404 extending outward from the end of the rod 402 of the elastic structural feature 403 is not limited to two, and can also be greater than two. A certain distance is formed between the elastic legs 404 to ensure that the rod 402 of the pin component 4 can smoothly pass through the square pin hole.

[0048] like Figure 7As shown, the distance H between the small protrusions 405 along the transverse direction of the pin member 4 is greater than the corresponding size of the pin hole 215 in the double-ear joint 212 of the movable half 2. Furthermore, the distance h between the head 401 and the small protrusions 405 along the longitudinal direction of the pin member 4 is equal to the sum of the lengths of the square pin holes 215 and 115 in the double-ear joint 212 of the movable half 2 and the single-ear joint 112 of the fixed half 1. Thus, after the rod 402 passes through the square pin hole, the head 401 can engage with one end of the square pin hole, while the small protrusions 405 can engage with the other end of the square pin hole, thereby longitudinally retaining the first joint portion 102 and the second joint portion 202 between the head 401 and the small protrusions 405 on the elastic leg 404.

[0049] According to one embodiment, the distance between the head portion 401 and the small protrusion 405 along the longitudinal direction of the pin member 4 is greater than the sum of the lengths of the square pin holes 215 and 115 on the double-ear joint 212 of the movable half 2 and the single-ear joint 112 of the fixed half 1. Thus, after the rod portion 402 passes through the square pin hole, the head portion 401 can engage with one end of the square pin hole, while the small protrusion 405 can engage with the other end of the square pin hole, thereby retaining the first joint portion 102 and the second joint portion 202 between the head portion 401 and the small protrusion 405 on the elastic leg 404 in the longitudinal direction.

[0050] Thus, when using the quick-release clamp according to the present invention to install pipes and cables that need to be fixed to the aircraft body structure, the fixed half 1 and the movable half 2 are placed relative to each other, so that the first surface S1 and the second surface S2 face each other, thereby forming a space S3 therebetween capable of receiving the pipes and cables to be installed. Subsequently, the cylindrical pin member 3 is sequentially inserted through the circular pin holes of the double-ear joint 211 and the single-ear joint 111 located on the same side of the movable half 2 and the fixed half 1. The ends of the cylindrical pin member 3 that emerge from the circular pin hole of the double-ear joint 211 are then processed so that the diameter of the two ends 301 is larger than the diameter of the pin hole 214 of the double-ear joint 211. This achieves a permanent connection between the movable half 2 and the fixed half 1 on one side, and the movable half 2 can rotate relative to the fixed half 1 about the pin member 3 on this side. Next, the rod portion 402 of the square pin member 4 is sequentially passed through the square pin holes 215 and 115 of the double-ear joint 212 and the single-ear joint 112 on the other side of the movable half 2 and the fixed half 1, thereby reliably connecting the fixed half 1 and the movable half 2 into a whole.

[0051] As the pin member 4 passes through the aligned square pin holes 115, 215, the small protrusions 405 on the two elastic legs 404 at the end of the rod portion 402 are squeezed by the pin hole walls, deforming toward each other within the gap, thereby allowing the rod portion 402 of the pin member 4 to pass through the square pin holes 115, 215. Subsequently, after the elastic legs 404 at the end of the rod portion 402 of the pin member 4 pass through the square pin holes 115, 215, the elastic legs 404 elastically return to their original shape, thereby preventing the rod portion 402 from moving in the opposite direction by cooperating with the small protrusions 405 on the elastic legs 404 and the end wall of the square pin hole 215 on the double-ear joint 212. This prevents the pin member 4 from moving in a direction opposite to the direction of passage after passing through the square pin holes 115, 215. At the same time, the head 401 of the pin member 4 also cooperates with the end wall of the square pin hole 115 on the double-ear joint 212 located on the other side of the movable half 2 to prevent the pin member 4 from moving further in the passing direction, and together with the small protrusion 405 on the elastic leg 404 that elastically returns to its original shape, firmly clamps the double-ear joint 212 and single-ear joint 112 of the movable half 2 and the fixed half 1 located therebetween, thereby achieving a compact connection between the fixed half 1 and the movable half 2.

[0052] It should be understood that the positions of the aforementioned pin holes 114 and 115 in the single-ear connectors 111 and 112, and the positions of the aforementioned pin holes 214 and 215 in the double-ear connectors 211 and 212, are not limited to the aforementioned intermediate positions and can be varied according to actual needs. The pin member 3 can be a cotter pin, a standard rivet, a custom rivet, or other connector, without limitation. Furthermore, the treatment of the two ends 301 of the pin member 3 can vary depending on the material used, and can include roughening, gluing, or thermoplastic treatment.

[0053] By way of example, the following describes, with reference to the accompanying drawings, a process of installing an object to be installed on an aircraft fuselage structure and removing the object to be installed from the aircraft fuselage structure using a quick-release clamp according to another embodiment of the present invention.

[0054] First, if Figure 1 As shown, the single-ear joint 111 of the fixed half 1 at one end wall 11 is arranged between the two ears 221, 231 of the double-ear joint 211 at one end wall 21 of the movable half 2, so that the pin hole 114 on the single-ear joint 111 is aligned with the pin hole 214 on the double-ear joint 211. Figure 3 As shown, a cylindrical pin member 3 is passed through the aligned pin holes 114 and 214, and then both ends of the pin member 3 are subjected to, for example, blunting, so that a permanent connection is formed between the pin member 3 and the single-ear joint 111 of the fixed half 1 and the double-ear joint 211 of the movable half 2, and the movable half 2 is allowed to rotate relative to the fixed half 1.

[0055] Next, the fixed half 1 together with the movable half 2 are detachably mounted on the aircraft body structure via the mounting seat 103 of the fixed half 1 , and the object to be mounted is placed on the first surface S1 of the fixed half 1 .

[0056] Subsequently, the movable half 2 is rotated toward the fixed half 1, so that the double-ear joint 212 on the other end wall 22 of the movable half 2 approaches the single-ear joint 112 on the other end wall 12 of the fixed half 1 until the single-ear joint 112 of the fixed half 1 is inserted between the two ears 222 and 232 of the double-ear joint 212 of the movable half 2, aligning the pin hole 215 on the double-ear joint 212 of the movable half 2 with the pin hole 115 on the single-ear joint 112 of the fixed half 1. At this point, the second surface S2 of the movable half 2 contacts the surface of the object to be mounted and cooperates with the first surface S1 of the fixed half 1 to form a space S3 between the two to receive the object to be mounted. Simultaneously, the second surface S2 of the movable half 2 also restricts the movement of the object to be mounted along the lateral direction of the quick-release clamp, thereby positioning the object to be mounted on the first surface S1 of the fixed half 1.

[0057] Finally, if Figure 2 As shown, the rod portion 402 of the pin member 4 is sequentially passed through the pin holes 215 and 115 on the aligned double-ear joint 212 of the movable half 2 and the single-ear joint 112 of the fixed half 1, and the second joint portion 202 and the first joint portion 102 are clamped between the head portion 401 of the pin member 4 and the small protrusion 405 on the elastic leg 404 at the end portion of the rod portion 402, thereby completing the fixation of the movable half 2 and the fixed half 1, and further realizing the clamping of the object to be installed on the quick-release clamp.

[0058] When the object to be installed in the quick-release clamp needs to be removed, the pin member 4 only needs to be pulled out from the pin holes 215 and 115 on the movable half 2 and the fixed half 1 in the direction opposite to the passing direction of the pin member 4.

[0059] The quick-release clamp provided by the present invention can achieve connection and locking of the two halves of the quick-release clamp through pin members 3 and 4. During pipeline installation, only pin members 3 and 4 are needed, without the use of fasteners such as bolts and nuts, to form a space S3 for receiving the pipeline between the opposing surfaces of the movable half 2 and the fixed half 1, thereby enabling rapid assembly and disassembly of the pipeline. By locking and fixing the pipeline with the quick-release clamp, maintenance personnel do not need to use tools when assembling and disassembling the pipeline, and can achieve single-handed operation, which greatly shortens maintenance time, reduces the requirements for maintenance space, and improves maintenance efficiency. Because the required assembly and disassembly space is small, the quick-release clamp can also be used in small spaces such as electronic compartments or cockpits.

[0060] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
