Abstract
Description
Technical Field
[0001] This application relates to the technical field of clamps, and in particular to a damage-resistant pipe connection clamp. Background Technology
[0002] Clamps, as a typical type of mechanical fastener, are widely used in pipeline connections, fluid transportation, automotive manufacturing, and aerospace, among other fields. Their core function is to achieve structural fixation through radial constraint. Traditional clamp structures are typically made of metal or polymer materials and are fastened using bolts, worm gears, or spring preload.
[0003] To improve convenience and reliability in pipe connections, clamps are often used for direct fixing. However, when using clamps, to ensure a tight connection, the clamps are usually adjusted to grip the pipe tightly, increasing friction. If the clamping force is too great, and the clamp and pipe are in rigid contact, it may damage the pipe. Furthermore, when connecting two pipes, relying solely on the contact between the clamp and the pipe wall for sealing can easily lead to liquid or gas leaks, causing connection failure. Utility Model Content
[0004] In order to reduce the possibility of damage to pipes when using clamps to connect pipes, this application provides a damage-resistant pipe connection clamp.
[0005] This application provides a damage-resistant pipe connection clamp, which adopts the following technical solution:
[0006] A damage-resistant pipe connection clamp for connecting a first pipe and a second pipe includes a sealing ring, a first half-ring, a second half-ring, and a fixing member. The ends of the first pipe and the second pipe can be inserted into the two ends of the sealing ring, respectively. The ends of the first half-ring and the second half-ring are arranged opposite to each other, and both ends can be connected and locked by the fixing member.
[0007] By adopting the above technical solution, a convenient connection between the first and second pipes is achieved. At the same time, a sealing ring is set for buffering, which effectively prevents damage caused by hard contact between the pipe and the clamp. The sealing ring can ensure the sealing of the connection, avoid liquid or gas leakage, and improve the reliability of the connection.
[0008] Optionally, the fastener includes a threaded rod, an end block, and a handle connected to each other. The end block is connected between the threaded rod and the handle. The first half-ring has a first radial section at both ends, and the second half-ring has a second radial section at both ends. The first radial section has a through hole, and the second radial section has a threaded hole. The threaded rod can pass through the through hole and be threadedly connected to the threaded hole. The diameter of the end block is larger than the diameter of the through hole.
[0009] By adopting the above technical solution, the fastener consists of a threaded rod, an end block, and a handle, which work together with the radial sections on the first and second half-rings to achieve a locking connection. The threaded connection between the threaded rod and the threaded hole provides a stable locking force, ensuring that the clamp will not loosen during use; at the same time, the handle facilitates the operator's application of force, improving installation efficiency and convenience.
[0010] Optionally, the sealing ring includes an outer sealing ring and an inner sealing ring. The inner sealing ring is circumferentially disposed on the inner sidewall of the outer sealing ring, and the inner sealing ring is disposed at the middle position of the outer sealing ring along the length direction of the outer sealing ring. When the first pipe and the second pipe are respectively inserted into the outer sealing ring, the end faces of the first pipe and the second pipe can respectively abut against both sides of the inner sealing ring.
[0011] By adopting the above technical solution, the combined design of the outer sealing ring and the inner sealing ring can effectively improve the sealing performance of the pipe connection. The inner sealing ring is set in the middle of the outer sealing ring, so that when the first pipe and the second pipe are inserted, their end faces can respectively abut against the two sides of the inner sealing ring, thereby forming a reliable sealing barrier to prevent liquid or gas leakage.
[0012] Optionally, deformation grooves are provided at intervals on the sidewalls of both the inner and outer sealing rings.
[0013] By adopting the above technical solution, deformation grooves are spaced apart on the sidewalls of both the inner and outer sealing rings, which allows the sealing rings to undergo controllable elastic deformation when squeezed by the pipe end face. The presence of deformation grooves enhances the flexibility of the sealing rings, enabling them to better conform to the pipe surface when subjected to force, thereby significantly reducing the possibility of leakage.
[0014] Optionally, both the first and second semi-rings are provided with positioning semi-rings on their inner sidewalls along the axial direction. The outer sidewalls of the first and second pipes are provided with positioning grooves in the circumferential direction. The outer sealing ring is located between the two positioning grooves. When the end faces of the first and second pipes abut against the sidewall of the inner sealing ring, the two positioning semi-rings on the first semi-ring and the two positioning semi-rings on the second semi-ring can be inserted into the positioning grooves on the first and second pipes respectively. At this time, the sidewall of the positioning semi-ring abuts against the sidewall of the positioning groove closest to the sealing ring.
[0015] By adopting the above technical solution, the cooperation between the positioning half-ring and the positioning groove can effectively prevent the relative displacement of the first half-ring and the second half-ring in the axial direction, thereby improving the overall stability of the clamp and enhancing the reliability of the pipeline connection.
[0016] Optionally, it also includes a clamping member, wherein the width of the positioning groove is greater than the width of the positioning half-ring. When the fixing member locks the first half-ring and the second half-ring, the clamping member can drive the first pipe and the second pipe to move closer to each other and clamp the inner sealing ring.
[0017] By adopting the above technical solution, the clamping component can push the first pipe and the second pipe closer to each other and press against the inner sealing ring by utilizing the space between the positioning groove and the positioning half ring when the fixing component locks the first half ring and the second half ring. The design of the clamping component ensures close contact between the pipe end face and the inner sealing ring, thereby significantly improving the sealing effect at the connection.
[0018] Optionally, the clamping member includes a first clamping block and a second clamping block. The thickness of the positioning half-ring is less than the depth of the positioning groove. A first sliding groove for the first clamping block to slide is formed on the side wall of the positioning half-ring facing the axis of the positioning groove. A second sliding groove for the second clamping block to slide is formed on the side wall of the positioning half-ring facing the inner sealing ring. The first sliding groove and the second sliding groove are connected. A first inclined surface is provided at one end of the first clamping block inserted into the first sliding groove. When the first half-ring and the second half-ring are fastened to the outer sealing ring, the outer end face of the second clamping block abuts against the side wall of the positioning groove, and the outer end face of the first clamping block abuts against the bottom wall of the positioning groove. When the fixing member drives the first half-ring and the second half-ring to move closer to each other, the first inclined surface of the first clamping block abuts against the end face of the second clamping block and drives the second clamping block to slide out towards the inner sealing ring.
[0019] By adopting the above technical solution, the cooperation of the first and second clamping blocks can effectively clamp the pipeline. Specifically, when the first inclined surface of the first clamping block abuts against the end face of the second clamping block, as the fixing component drives the first half ring and the second half ring to move closer to each other, the first clamping block will push the second clamping block to slide out towards the inner sealing ring, thereby further increasing the contact pressure between the first and second pipelines and the inner sealing ring, ensuring the sealing performance of the connection.
[0020] Optionally, multiple sets of the abutting members are provided at intervals along the extension direction of the second semi-ring.
[0021] By adopting the above technical solution, multiple sets of clamping members are spaced apart in the extension direction of the second semi-ring, so that when the first and second pipes are locked by the fixing members, they can be subjected to uniform forces at multiple positions, thereby further improving the sealing performance between the pipes and the inner sealing ring.
[0022] Optionally, a first limiting block is provided on the side wall of the first abutting block, and a first limiting groove is provided on the side wall of the positioning semi-ring for the limiting block to slide, the extending direction of the first limiting groove being parallel to the extending direction of the first sliding groove; a second limiting block is provided on the side wall of the second abutting block, and a second limiting groove is provided on the side wall of the positioning semi-ring for the limiting block to slide, the extending direction of the second limiting groove being parallel to the extending direction of the second sliding groove.
[0023] By adopting the above technical solution, the cooperation between the first limiting block and the first limiting groove, and the cooperation between the second limiting block and the second limiting groove, can prevent the first abutting block and the second abutting block from dislodging from the first sliding groove or the second sliding groove.
[0024] Optionally, the second abutment block has a second inclined surface at one end near the inner sealing ring, and when the positioning half-ring is inserted into the positioning groove, the second inclined surface faces the positioning groove.
[0025] By adopting the above technical solution, a second inclined surface is provided at the end of the second abutment block near the inner sealing ring, so that the second inclined surface can guide the second abutment block to slide more smoothly during the process of the positioning half ring being inserted into the positioning groove, reducing the jamming phenomenon.
[0026] In summary, this application includes at least one of the following beneficial effects:
[0027] 1. By setting a sealing ring and locking the first and second half-rings together with the fasteners, the pipe damage caused by rigid contact of traditional clamps can be effectively avoided, thus improving the safety and reliability of the connection;
[0028] 2. The design of the inner and outer sealing rings in the sealing ring significantly enhances the sealing performance of the pipe connection, effectively preventing liquid or gas leakage and ensuring the stability of the connection. Attached Figure Description

Detailed Implementation
[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0035] Example 1:
[0036] This application discloses a damage-resistant pipe connection clamp; see reference Figure 1 and Figure 2 The clamp includes a sealing ring 1, a first half-ring 2, a second half-ring 3, and a fixing member 4. The first half-ring 2 and the second half-ring 3 are both arc-shaped metal half-rings with their ends facing each other, and both ends can be connected and locked by the fixing member 4. The sealing ring 1 is made of a flexible material, such as rubber or silicone. In use, the ends of the first pipe 101 and the second pipe 102 to be connected are first inserted into the two ends of the sealing ring 1, respectively. Then, the first half-ring 2 and the second half-ring 3 are clamped together and tightened to the outside of the sealing ring 1 by the fixing member 4. Simultaneously, the first half-ring 2 and the second half-ring 3 secure the sealing ring 1 at the connection point of the first pipe 101 and the second pipe 102. This not only connects and fixes the first pipe 101 and the second pipe 102, but also provides a buffer between the first half-ring 2, the second half-ring 3, and the pipes through the flexible sealing ring 1, preventing damage to the pipes. Furthermore, the sealing ring 1 improves the sealing performance at the connection point of the first pipe 101 and the second pipe 102.
[0037] Reference Figure 1 and Figure 2In this embodiment of the application, the first half-ring 2 is fixedly connected to both ends of the first radial segment 21, and the second half-ring 3 is fixedly connected to both ends of the second radial segment 32; when the first half-ring 2 and the second half-ring 3 are both attached to the pipe, the first radial segment 21 and the second radial segment 32 are parallel to each other and arranged opposite to each other. The fastener 4 includes a threaded rod 41, an end block 42, and a handle 43 connected to each other. The threaded rod 41 has an external thread, a through hole in the first radial section 21, and a threaded hole in the second radial section 32. The threaded rod 41 can pass through the through hole and be threadedly connected to the threaded hole. The end block 42 is connected to the threaded rod 41. The diameter of the end block 42 is larger than the diameter of the through hole, thus serving as a limit. When the end face of the end block 42 abuts against the first radial section 21, continuing to rotate the threaded rod 41 can drive the second radial section 32 to move continuously toward the first radial section 21, thereby clamping the first half ring 2 and the second half ring 3. The handle 43 is connected to the end of the end block 42 away from the threaded rod 41. The threaded rod 41 can be easily rotated through the handle 43. The handle 43 can also be designed as a plate structure to facilitate the application of force.
[0038] Optionally, to further improve the locking effect between the first half-ring 2 and the second half-ring 3, a nut can be added to further lock the threaded rod 41 after it has rotated into place.
[0039] Reference Figure 2 and Figure 3 Furthermore, the sealing ring 1 also includes an outer sealing ring 11 and an inner sealing ring 12. The inner sealing ring 12 is embedded in the inner wall of the outer sealing ring 11 and is positioned at the middle along the length of the outer sealing ring 11. The inner sealing ring 12 and the outer sealing ring 11 are preferably manufactured as a single piece. The inner diameter of the inner sealing ring 12 is preferably the same as the inner diameter of the first pipe 101 and the second pipe 102. The inner diameter of the outer sealing ring 11 can be the same as the outer diameter of the first pipe 101 and the second pipe 102, or it can be slightly smaller than the outer diameter of the first pipe 101 and the second pipe 102. When the first pipe 101 and the second pipe 102 are respectively inserted into the outer sealing ring 11, the two pipe end faces can respectively abut against both sides of the inner sealing ring 12, forming a double sealing effect.
[0040] Preferably, deformation grooves are provided at intervals on both side walls of the inner sealing ring 12 and the outer side wall of the outer sealing ring 11. When the outer sealing ring 11 or the inner sealing ring 12 is compressed, the deformation grooves can provide more deformation space, thereby further improving the sealing effect.
[0041] Reference Figure 2 and Figure 3In an optional embodiment, a positioning half-ring 5 is further provided on the inner sidewall of the first half-ring 2 and the second half-ring 3. The positioning half-ring 5 is also made of metal and is respectively provided at both ends of the first half-ring 2 or the second half-ring 3 along the axial direction. The ends of the first pipe 101 and the second pipe 102 are both provided with positioning grooves 103 circumferentially. When the first half-ring 2 and the second half-ring 3 are positioned on the pipe, the positioning half-rings 5 at both ends can be inserted into the positioning grooves 103 on the two pipes respectively. At this time, the sidewalls of the positioning half-rings 5 that are close to each other at both ends can abut against the sidewalls of the positioning grooves 103 that are close to the sealing ring 1 respectively. It should be noted that when the ends of the first pipe 101 and the second pipe 102 abut against the sidewall of the inner sealing ring 12, the outer sealing ring 11 can be located between the two positioning grooves 103, that is, the length of the outer sealing ring 11 is less than the distance between the two positioning grooves 103, so as to avoid the outer sealing ring 11 affecting the insertion of the positioning half-ring 5 into the positioning groove 103. By adding a positioning semi-ring 5, the stability of the connection between the first pipe 101 and the second pipe 102 can be improved, and the distance between the first pipe 101 and the second pipe 102 can be limited.
[0042] The implementation principle of the anti-damage pipe connection clamp in this application embodiment is as follows: By setting a sealing ring 1, a buffer can be formed between the pipe and the first half-ring 2 and the second half-ring 3, avoiding damage to the pipe caused by hard contact; at the same time, the double sealing structure of the outer sealing ring 11 and the inner sealing ring 12, as well as the cooperation between the positioning half-ring 5 and the positioning groove 103, achieve high sealing performance at the pipe connection. In addition, the insertion design of the positioning half-ring 5 effectively prevents the pipe from shifting during the connection process, thereby improving the overall reliability of the connection.
[0043] Example 2:
[0044] The difference between this embodiment and the previous embodiment is the addition of a clamping member 6, which further improves the tightness of the pipe connection and the waterproof performance of the connection. In this embodiment, when the fixing member 4 locks the first half-ring 2 and the second half-ring 3, that is, when the force between the threaded rod 41 and the threaded hole drives the first half-ring 2 and the second half-ring 3 to move closer to each other and squeeze the outer sealing ring 11, the clamping member 6 can simultaneously drive the first pipe 101 and the second pipe 102 to move closer to each other and clamp the inner sealing ring 12.
[0045] Reference Figure 3 and Figure 4Specifically, the clamping element 6 includes a first clamping block 61 and a second clamping block 62. The first clamping block 61 and the second clamping block 62 are integrally formed into small rectangular blocks; a first sliding groove 51 for sliding the first clamping block 61 is formed on the side wall of the positioning half-ring 5 facing the axis of the positioning groove 103, and a second sliding groove 52 for sliding the second clamping block 62 is formed on the side wall of the positioning half-ring 5 facing the inner sealing ring 12. The first sliding groove 51 and the second sliding groove 52 are connected, and the extension direction of the first sliding groove 51 and the extension direction of the second sliding groove 52 are preferably perpendicular to each other.
[0046] It should be noted that in this embodiment, the width of the positioning groove 103 is greater than the width of the positioning half-ring 5. When the side wall of the positioning half-ring 5 abuts against the side wall of the positioning groove 103 near the sealing ring 1, there is a gap between the other side wall of the positioning half-ring 5 and the side wall of the positioning groove 103. Meanwhile, the thickness of the positioning half-ring 5 is less than the depth of the positioning groove 103. When the first half-ring 2 and the second half-ring 3 are fastened to the outer sealing ring 11, the positioning half-ring 5 is inserted into the positioning groove 103. At this time, the side wall of the positioning half-ring 5 abuts against the side wall of the positioning groove 103. The end of the second abutting block 62 near the inner sealing ring 12, that is, the outer end of the second abutting block 62 abuts against the side wall of the positioning groove 103. The end of the first abutting block 61 near the positioning groove 103, that is, the outer end of the first abutting block 61 abuts against the bottom wall of the positioning groove 103. The end of the first abutting block 61 inserted into the first sliding groove 51, that is, the inner end of the first abutting block 61, is provided with a first inclined surface 612. The first inclined surface 612 abuts against the inner end face of the second abutting block 62.
[0047] When the threaded rod 41 drives the first half-ring 2 and the second half-ring 3 to approach each other, the first half-ring 2 and the second half-ring 3 will compress the outer sealing ring 11; at the same time, it will drive the positioning half-ring 5 to move towards the bottom wall of the positioning groove 103. Under the force of the bottom wall of the positioning groove 103, the first abutting block 61 slides into the first sliding groove 51. Under the pressure of the first inclined surface 612 and the inner end face of the second abutting block 62, the second abutting block 62 is driven to slide out of the second sliding groove 52 towards the inner sealing ring 12, thereby driving the first pipe 101 and the second pipe 102 to approach each other in the opposite direction, compressing the inner sealing ring 12. Multiple sets of abutting members 6 can be arranged at intervals along the extension direction of the second half-ring 3, which can provide a more uniform distribution of clamping force, thereby further improving the sealing performance.
[0048] Reference Figure 3 and Figure 4Furthermore, a first limiting block 611 is provided on the side wall of the first abutting block 61, and a first limiting groove for sliding of the limiting block is provided on the side wall of the positioning semi-ring 5. The extension direction of the first limiting groove is parallel to the extension direction of the first sliding groove 51. A second limiting block 621 is provided on the side wall of the second abutting block 62, and a second limiting groove for sliding of the limiting block is provided on the side wall of the positioning semi-ring 5. The extension direction of the second limiting groove is parallel to the extension direction of the second sliding groove 52. By adding the first limiting block 611 and the first limiting groove, the first abutting block 61 or the second abutting block 62 can be prevented from dislodging from the positioning semi-ring 5. For illustrative purposes only, during production, the parts of the positioning semi-ring 5 that require the installation of the abutting element 6 can be installed separately. That is, the first abutting block 61, the first limiting block 611, the second abutting block 62 and the second limiting block 621 are first installed into the corresponding grooves, and then welded to form the final structure of the positioning semi-ring 5.
[0049] Reference Figure 3 and Figure 4 In an optional embodiment, the second abutment block 62 has a second inclined surface 622 at one end near the inner sealing ring 12. When the positioning half-ring 5 is inserted into the positioning groove 103, the second inclined surface 622 faces the positioning groove 103. By setting the second inclined surface 622, when the positioning half-ring 5 is inserted into the positioning groove 103, even if the outer end of the second abutment block 62 slides out of the second sliding groove 52, the second inclined surface 622 can be driven to slide into the second sliding groove 52 under the contact between the pipe and the pipe, thus improving the convenience of operation.
[0050] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
