Description

Technical Field

[0001] The present application relates to the field of clamps, and in particular to a clamp mechanism for a pipe. Background Art

[0002] A clamp is a metal or plastic product used to fasten and connect round or tubular objects such as pipes, rods, or cables. It typically consists of two semicircular parts that can be connected together with bolts, nuts, or other fasteners to form a complete ring, which can tightly hold and secure the target object.

[0003] Patent application number CN108591645A discloses a clamp comprising an upper clamp and a lower clamp. The upper and lower clamps are connected on one side by a rotating structure and on the other side by a movable structure. The movable structure comprises a clamping block, a clamping rod, and a connecting rod. The clamping block is mounted on the upper clamp. The lower clamp is rotatably connected to the clamping rod via a connecting rod. The lower clamp is rotatably connected to the clamping rod via two connecting rods. The ends of the connecting rods are rotatably connected to the lower clamp and the clamping rod via rotating shafts. The rotating structure is a rotating shaft. The upper and lower clamps are provided with protrusions through which the rotating shaft passes. The upper and lower clamps have a "["-shaped" cross-section and are forged from cast iron. To connect two pipes, an annular groove can be provided near the ends of the two pipes, allowing the edges on both sides of the width of the upper and lower clamps to fit into the annular groove. The clamping block is then inserted between the two connecting rods. The clamping rod is then rotated, causing the clamps to lock the two pipes together, completing the connection.

[0004] However, for a straight pipe without an annular groove at the end, the locking degree of the clamp on such a straight pipe is relatively weak, and there is room for improvement. Utility Model Content

[0005] In order to improve the problem that the clamp in the related art has a weak locking degree on the straight pipe, the present application provides a pipe clamp mechanism.

[0006] This application provides a pipe clamp mechanism that adopts the following technical solution:

[0007] A pipe clamp mechanism includes a clamp body, which is annular and has a clamping channel formed inside the clamp body. A damping member is provided on the inside of the clamp body, which protrudes toward the inside of the clamp body and is used to press between the inside of the clamp body and the object clamped by the clamp body.

[0008] By adopting this technical solution, in actual use, a straight pipe can be inserted into the clamping channel; the clamp body then clamps the straight pipe, and the damping element presses against the straight pipe and the inner side of the clamp body, increasing the friction between the clamp body and the straight pipe. In this way, the clamp mechanism can tighten the straight pipe more tightly.

[0009] Preferably, the damping member comprises a damping block, and a claw is fixed on the side of the damping block facing away from the inner wall of the hoop.

[0010] By adopting the above technical solution, in actual use, the hoop body holds the straight pipe tightly and the claws press against the straight pipe, which helps to ensure the friction force of the damping member on the straight pipe and helps to ensure the locking degree of the hoop mechanism on the straight pipe.

[0011] Preferably, the width direction of the hoop body is arranged along the clamping channel, and both sides of the hoop body in its width direction are clamping areas. The damping block and the claw are both located in the clamping area, and a guide slope is provided on the side of the claw away from the other clamping area. The guide slope is used to guide the claw to deform toward the other clamping area when it is pressurized.

[0012] By adopting the above technical solution, when the hoop body clamps the straight pipe, the claws press against the straight pipe. Under the guidance of the guiding inclined surface, the straight pipe will press the claws and cause the claws to deform toward the other clamping area. At the same time, the claws will drag the straight pipe toward the other clamping area, which helps to ensure the degree of locking of the straight pipe by the clamp mechanism.

[0013] It should be pointed out that for high-hardness metals such as cast steel and stainless steel, they will still deform under pressure, but many deformations are difficult to detect with the naked eye.

[0014] Preferably, a mounting ring plate is provided in the hoop body, a disconnection opening is provided on one side of the mounting ring plate, and the damping block is provided on the mounting ring plate.

[0015] By adopting the above technical solution, the damping block is arranged on the mounting ring plate, thereby facilitating the production of the pipe clamp structure.

[0016] It should be pointed out that the hoop body in the industry is usually produced by casting, stamping and other methods. It is more convenient to produce the damping block and the claw separately from the hoop body.

[0017] Preferably, a stepped groove is provided on the mounting ring plate from the outside to the inside, and a lap portion is provided on the side of the damping block close to the inner wall of the hoop body. The damping block passes through the stepped groove from the outside of the mounting ring plate, and the lap portion abuts against the step surface of the stepped groove. The damping block is located on the side of the lap portion away from the inner wall of the hoop body, passes through the stepped groove and penetrates into the inner side of the mounting ring plate.

[0018] By adopting the above technical solution, the damping block and the mounting ring plate can be produced separately and assembled, thereby facilitating the normal progress of production operations.

[0019] Preferably, a mounting ring groove for embedding a mounting ring plate is provided around the inner side of the hoop body.

[0020] By adopting the above technical solution, when the hoop body is tightly holding the straight pipe, the mounting ring plate is located in the mounting ring groove, thereby ensuring the stability of the connection between the mounting ring plate and the hoop body.

[0021] Preferably, the bottom wall of the mounting ring groove is provided with a guiding inclined surface for guiding the damping block to move toward another clamping area.

[0022] By adopting the above technical solution, in actual use, the guide slope can guide the damping block and the mounting plate to move toward the other clamping area, and the clamping claw will drag the straight pipe toward the other clamping area, which helps to ensure the locking degree of the straight pipe by the clamp mechanism.

[0023] Preferably, a sealing ring is provided on the hoop body between the two clamping areas.

[0024] By adopting the above technical solution, when the hoop body hugs the two straight pipes and connects the two straight pipes, the sealing ring can seal the connection between the two straight pipes, thereby reducing the leakage of the circulating medium in the straight pipes.

[0025] Preferably, the hoop body includes a first half hoop and a second half hoop, the first half hoop and the second half hoop are both arc-shaped, the clamping channel is formed between the first half hoop and the second half hoop, and connecting ears are fixed at both ends of the arc-shaped direction of the first half hoop and the second half hoop, and the connecting ears of the first half hoop and the second half hoop correspond to each other one by one and are connected by fasteners.

[0026] By adopting the above technical solution, the first half hoop and the second half hoop are connected by a fastener, which facilitates the clamping operation of the pipe by the pipe clamp mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] The embodiment of the present application discloses a pipe clamp mechanism.

[0034] Reference Figure 1 and Figure 2 The pipe clamp mechanism includes a clamp body 1, which is annular and has a clamping channel 11 formed on the inner side of the clamp body 1. The width direction of the clamp body 1 is arranged along the clamping channel 11, and both sides of the clamp body 1 in the width direction are clamping areas, and the two clamping areas correspond to the ends of the two straight pipes 100 respectively. Damping members 2 are provided in the two clamping areas of the clamp body 1, and each damping member 2 protrudes toward the inner side of the clamp body 1 and is used to press tightly between the inner side of the clamp body 1 and the corresponding straight pipe 100. When the two straight pipes 100 are connected, the ends of the two straight pipes 100 are respectively inserted into the two clamping areas, and then the clamp body 1 can clamp the ends of the two straight pipes 100, and the damping members 2 in the two clamping areas are pressed tightly between the hoop body 1 and the corresponding straight pipe 100.

[0035] Specifically, see Figure 2 and Figure 3 The hoop body 1 includes a first hoop half 12 and a second hoop half 13. Both the first hoop half 12 and the second hoop half 13 are arc-shaped and symmetrically arranged. The clamping channel 11 is formed between the first hoop half 12 and the second hoop half 13. Connecting ears 14 are fixed to both ends of the arc-shaped first hoop half 12 and the second hoop half 13. The connecting ears 14 of the first hoop half 12 and the connecting ears 14 of the second hoop half 13 correspond to each other and are connected by fasteners 15. In this embodiment, the fasteners 15 are bolts and nuts that are used to lock the two sets of connecting ears 14.

[0036] The structures of the damping members 2 in the two holding areas are symmetrical to each other and are installed in the same manner. The damping member 2 in one of the holding areas is now taken as an example for explanation.

[0037] See also Figure 2 and Figure 4A mounting ring groove 16 is provided on the inner side of the hoop body 1 within the clamping area. The mounting ring groove 16 is arranged around the hoop body 1 and is divided into two parts, one on the first hoop half 12 and the other on the second hoop half 13. A mounting ring plate 3 is provided within the mounting ring groove 16. A disconnection opening 31 is provided on one side of the mounting ring plate 3, and the damping member 2 is located on the mounting ring plate 3.

[0038] A stepped groove 32 is formed on the mounting ring plate 3 from the outside to the inside, and the length direction of the stepped groove 32 is arranged along the width direction of the hoop body 1. The damping element 2 includes a damping block 21. The damping block 21 has an integrally formed overlapping portion 22 on the side close to the inner wall of the hoop body 1. The length direction of the overlapping portion 22 is arranged along the width direction of the hoop body 1. The damping block 21 penetrates the stepped groove 32 from the outside of the mounting ring plate 3, and the two sides of the overlapping portion 22 in the length direction overlap the stepped surfaces on both sides of the stepped groove 32 in the length direction. The damping block 21 is located on the side of the overlapping portion 22 facing away from the inner wall of the hoop body 1, penetrates the stepped groove 32, and penetrates into the inside of the mounting ring plate 3. A claw 23 is integrally formed on the side of the damping block 21 facing away from the overlap portion 22. A guide slope 231 is provided on the claw 23 facing away from the other clamping area and the damping block 21. Multiple claws 23 are provided on the damping block 21 along the width of the hoop body 1, with each guide slope 231 corresponding to each claw 23. In this embodiment, four claws 23 are provided on the damping block 21 along the width of the hoop body 1. Furthermore, multiple stepped grooves 32 are evenly spaced around the axis of the mounting ring plate 3. Both the damping block 21 and the overlap portion 22 correspond to the stepped grooves 32 in a one-to-one manner, and the claws 23 are provided corresponding to the damping block 21.

[0039] At the same time, the mounting ring grooves 16 correspond one-to-one with the clamping areas. The bottom walls of both mounting ring grooves 16 are provided with guide slopes 161 for guiding the damping block 21 toward the other clamping area, with the two guide slopes 161 facing each other. Furthermore, each overlap portion 22 is provided with a mating slope 221 on one side near the guide slope 161. The mating slopes 221 are arranged opposite each other. When the pipe is clamped by the clamp structure, the guide slopes 161 and the mating slopes 221 abut.

[0040] In actual use, the hoop body 1 can clamp the ends of the two straight tubes 100, and the guide bevel 161 and the matching bevel 221 abut against each other, which will push the damping blocks 21 in the two clamping areas closer to each other; at the same time, each claw 23 will press against the straight tube 100, and under the action of the guide bevel 231, the claws 23 in the two clamping areas will deform between the two, and at the same time, the claws 23 at the two clamping areas will respectively drag the two straight tubes 100 closer to each other.

[0041] It should be pointed out that in this embodiment, the hoop body 1, the mounting ring plate 3, the damping block 21, the overlapping portion 22 and the claw 23 are all made of steel, the compression deformation of the claw 23 is relatively small, and the dragging displacement of the straight pipe 100 by the claw 23 is also relatively small.

[0042] See also Figure 2 and Figure 3 In order to ensure the sealing between the two straight pipes 100, an annular embedding groove 17 is opened on the inner side of the hoop body 1 between the two clamping areas. The annular embedding groove 17 is coaxial with the hoop body 1. The annular embedding groove 17 is divided into two parts and is opened on the first half hoop 12 and the second half hoop 13 respectively. In addition, a sealing ring 4 is embedded in the annular embedding groove 17.

[0043] The pipe clamp mechanism of the present embodiment is implemented as follows: in actual use, the ends of two straight pipes 100 are inserted into the two clamping zones, respectively. Then, the first and second clamp halves 12, 13 are locked together using the fastener 15. The guide bevel 161 and the mating bevel 221 abut against each other, pushing the damping blocks 21 in the two clamping zones toward each other. Simultaneously, each claw 23 abuts against the straight pipe 100. Under the action of the guide bevel 231, the claws 23 in the two clamping zones deform toward each other, simultaneously pulling the two straight pipes 100 toward each other. Furthermore, the sealing ring 4 abuts against the connection between the two straight pipes 100, thereby sealing the connection.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
