Tamperproof pipe clamp

Abstract

This utility model discloses an anti-disassembly pipe clamp, including a clamp body and a locking body. Before use, the anti-disassembly pipe clamp is in the unfolded position. When in use, the second clamp body is bent and rotated relative to the first clamp body to the locking position via the first flexible connecting part, clamping the pipe. Then, the locking body is inserted into the first and second insertion holes to prevent the first and second clamp bodies from opening. At this time, the positioning part and the mating part of the locking body are fixedly engaged, fixing the locking body so that it cannot disengage from the first and second insertion holes, thus preventing the pipe clamp from being completely disassembled and achieving the anti-disassembly function. Since the first clamp body, the first flexible connecting part, and the second clamp body are integrally molded, the number of parts is reduced. The three components do not require assembly before use and can be directly used, thus facilitating production and reducing costs.

Description

Technical Field

[0001] This utility model relates to pipe clamps, and more particularly to a pipe clamp that is resistant to disassembly. Background Technology

[0002] Refrigeration equipment contains pipes for supplying refrigerant or other fluids. Some pipe joints require pipe clamps for protection. One existing pipe clamp, designed to prevent unauthorized disassembly, includes a first clamp, a second clamp, a pivot, a locking element, and a locking mechanism. The first end of the first clamp is pivotally connected to the first end of the second clamp via the pivot. The second end of both the first and second clamps has a first insertion hole. When the first and second clamps are rotated and engaged, the first and second insertion holes align, and the locking element is installed in the first insertion hole. The locking element can then be inserted into both the first and second insertion holes, preventing the first clamp from rotating relative to the second clamp. The locking element also secures the locking element, preventing it from disengaging from either insertion hole, thus preventing disassembly. However, this type of pipe clamp has a large number of parts, making production and use inconvenient and costly. Utility Model Content

[0022] Reference Figures 1 to 3This utility model provides an anti-disassembly pipe clamp, comprising a clamp body 100 and a locking body 200. The clamp body 100 includes a first clamp body 110, a second clamp body 120, and a first flexible connecting portion 130. The first end of the first clamp body 110 is connected to the first end of the second clamp body 120 via the first flexible connecting portion 130. The second end of the first clamp body 110 is provided with a first insertion hole 111, and the second end of the second clamp body 120 is provided with a second insertion hole 121. The first insertion hole 111 is provided with a positioning portion 112. The second clamp body 120 can rotate relative to the first clamp body 110 to an unfolded position or a locked position via the first flexible connecting portion 130. In the unfolded position, the second clamp body 120 is unfolded relative to the first clamp body 110; in the locked position, the first clamp body 120 is locked. The second end of 10 is opposite to the second end of the second buckle body 120. The first insertion hole 111 and the second insertion hole 121 are coaxially opposite each other. The first buckle body 110 and the second buckle body 120 enclose each other to form a clamping cavity. The locking body 200 is provided with a mating part 210. When the clamping body 100 is in the buckling position, the locking body 200 can be inserted into the first insertion hole 111 and the second insertion hole 121 and lock the position of the second buckle body 120 relative to the first buckle body 110. The positioning part 112 cooperates with the mating part 210 and fixes the position of the locking body 200 relative to the clamping body 100. The first buckle body 110, the second buckle body 120 and the first flexible connecting part 130 are integrally formed parts.

[0023] Before use, the anti-disassembly pipe clamp is in the unfolded position. When the pipe clamp is used, the second clamp body 120 is bent and rotated relative to the first clamp body 110 to the clamping position through the first flexible connecting part 130 to clamp the pipe. Then, the locking body 200 is inserted into the first insertion hole 111 and the second insertion hole 121 to prevent the first clamp body 110 and the second clamp body 120 from opening. At this time, the positioning part 112 and the mating part 210 of the locking body 200 are fixedly engaged to fix the locking body 200, so that the locking body 200 cannot be dislodged from the first insertion hole 111 and the second insertion hole 121, thereby realizing that the pipe clamp cannot be completely disassembled and realizing the anti-disassembly function. Since the first clamp body 110, the first flexible connecting part 130 and the second clamp body 120 are integrally formed parts, the number of parts is reduced. The three parts do not need to be assembled before use and can be used directly, which facilitates production and reduces costs.

[0024] It is understood that in some other embodiments, the positioning part 112 may also be provided in the second socket 121, and those skilled in the art may choose according to actual needs.

[0025] In this embodiment, the locking body 200 is connected to the clamping body 100 via the second flexible connecting portion 300. The locking body 200, the second flexible connecting portion 300, and the clamping body 100 are integrally molded plastic parts. Specifically, the locking body 200, the second flexible connecting portion 300, and the clamping body 100 are integrally molded plastic parts, namely, the locking body 200, the second flexible connecting portion 300, the first buckle 110, the second buckle 120, and the first flexible connecting portion 130 are integrally molded plastic parts. The first flexible connecting portion 130 is formed by the inherent flexibility of the plastic, replacing the function of a pivot and allowing the second buckle 120 to rotate relative to the first buckle 110. Furthermore, the locking body 200 can move relative to the clamping body 100 to the position where it is inserted into the first insertion hole 111 and the second insertion hole 121. The locking body 200 and the second flexible connecting portion 300 are also integrally molded with the clamping body 100, further reducing the number of parts. No additional parts assembly is required before use, facilitating production and use, and reducing costs.

[0026] In the embodiments, reference is made to Figure 1 The second flexible connecting part 300 is strip-shaped. One end of the second flexible connecting part 300 along its length is connected to the locking body 200, and the other end of the second flexible connecting part 300 along its length is connected to the first buckle body 110. The aforementioned second flexible connecting part 300 has good flexibility, which facilitates the movement of the locking body 200, and is relatively simple and convenient to process and use.

[0027] Specifically, when using the locking body 200, if the second flexible connecting part 300 is long, the locking body 200 can be directly inserted into the first socket 111 and the second socket 121; alternatively, the second flexible connecting part 300 can be cut off with scissors, and then the locking body 200 can be directly inserted into the first socket 111 and the second socket 121. Those skilled in the art can choose according to actual needs.

[0028] It is understood that in some other embodiments, the other end of the second flexible connection portion 300 may also be connected to the second buckle body 120, and those skilled in the art may choose according to actual needs.

[0029] In the embodiments, reference is made to Figure 1 The first flexible connecting portion 130 is strip-shaped. One end of the first flexible connecting portion 130 along the width direction is connected to the first buckle body 110, and the other end of the first flexible connecting portion 130 along the width direction is connected to the second buckle body 120. The length direction of the first flexible connecting portion 130 is parallel to the hole axis direction of the first insertion hole 111. The aforementioned first flexible connecting portion 130 can have a relatively long connection dimension with the first buckle body 110 and the second buckle body 120, and is not easily broken when subjected to external force, thus improving the anti-disassembly effect.

[0030] Specifically, the first flexible connecting part 130 is in the shape of a flat strip, which gives the first flexible connecting part 130 good bending performance.

[0031] In the embodiments, reference is made to Figure 3 The positioning part 112 is configured as an annular rib, which surrounds the hole axis of the first insertion hole 111 and is set on the hole wall of the first insertion hole 111. The mating part 210 is configured with a reversible block, one end of which is provided with a guide slope 211 and the other end of which is provided with a stop surface 212. In the locking position, the annular rib can abut against the stop surface 212 to prevent the locking body 200 from disengaging from the first insertion hole 111.

[0032] During the insertion of the locking body 200 into the first insertion hole 111, the guide ramp 211 abuts against the annular protrusion, causing a slight elastic deformation of the locking body 200, allowing the anti-reverse block to pass over the annular protrusion. After insertion, the annular protrusion abuts against the stop surface 212, preventing the locking body 200 from disengaging from the first insertion hole 111, thus preventing the locking body 200 from being pulled out and ensuring the pipe clamp can be completely disassembled. The aforementioned positioning part 112 and mating part 210 have a relatively simple structure, and the method of fixing the locking body 200 is reliable.

[0033] In the embodiments, reference is made to Figure 2 The locking body 200 includes a cap 220 and a body 230. The diameter of the cap 220 is larger than the diameter of the body 230. A check block is connected to the body 230. In the engaged position, an annular rib is located between the cap 220 and the check block. When engaged, the annular rib's position between the cap 220 and the check block ensures that the locking body 200 remains relatively stable after insertion, preventing it from being pulled out or over-inserted.

[0034] In the embodiments, reference is made to Figure 2 The rod body 230 is provided with a first rod segment 231 and two pairs of second rod segments 232. One end of the rod cap 220 is connected to one end of the first rod segment 231 through the second rod segment 232. The two pairs of second rod segments 232 are arranged at intervals. An elastic reinforcing hole 233 is formed between the rod cap 220, the first rod segment 231 and the second rod segment 232. A backstop block is connected to the second rod segment 232. By opening the elastic reinforcing hole 233 in the rod body 230, that is, the cross-section of the second rod segment 232 is smaller, making it easier to elastically deform. Since the backstop block is connected to the second rod segment 232, that is, the backstop block is easier to pass over the annular rib, so that the locking body 200 does not require much force to be inserted into place, reducing the difficulty for production personnel to install the pipe clamp.

[0035] Specifically, anti-reverse blocks are provided at both second rod sections 232, and the anti-reverse blocks are arranged in an approximately circular manner to reduce the risk of the locking body 200 coming out of the first insertion hole 111.

[0036] It is conceivable that the positioning part 112 can also be an annular groove, and the mating part 210 can be a reversible block. One side of the reversible block is provided with a guide slope 211, and the other side is provided with a stop surface 212. When the locking body 200 is inserted into the first insertion hole 111, the guide slope 211 abuts against the hole wall of the first insertion hole 111, causing the reversible block to elastically shrink. When the reversible block enters the annular groove, the reversible block returns to its original position and is embedded in the annular groove. At this time, the stop surface 212 abuts against the groove wall of the annular groove to fix the locking body 200. Alternatively, the positioning part 112 can also be a reversible block, and the mating part 210 can be an annular rib.

[0037] In the embodiments, reference is made to Figure 1 The first buckle body 110 has two first insertion holes 111, which are spaced apart. In the buckling position, the second insertion hole 121 is located between the two first insertion holes 111. Two locking bodies 200 are provided, each corresponding to one of the first insertion holes 111, and both locking bodies 200 are inserted into the same second insertion hole 121. By providing two first insertion holes 111 and two locking bodies 200, which correspond one-to-one, the pipe clamp buckle can still have good anti-tampering performance and good force balance even when it is long. Specifically, since the two first insertion holes 111 correspond to the same second insertion hole 121, the depth to which each locking body 200 is inserted into the second insertion hole 121 does not exceed half the total depth of the second insertion hole 121, eliminating the need to manufacture two second insertion holes 121 and reducing the manufacturing difficulty of the pipe clamp buckle.

[0038] In implementation, refer to Figure 1 The second buckle body 120 is positioned relative to the rotation axis of the first buckle body 110 along a first direction. The first buckle body 110 has a first groove 113, and the first groove 113 has first notches 114 on both sides along the first direction. The second buckle body 120 has a second groove 122, and the second groove 122 has second notches 123 on both sides along the first direction. In the buckling position, the opening of the first groove 113 aligns with the opening of the second groove 122 to form a clamping cavity. The first notches 114 and second notches 123 are opposite to each other to form a through hole. The through hole formed by the first notches 114 and second notches 123 can avoid the pipe, and the clamping cavity formed by the first grooves 113 and second grooves 122 can accommodate the structure at the pipe joint, so that the pipe clamp will not interfere with the pipe joint.

[0039] In the embodiments, reference is made to Figure 1 The hole axis of the first insertion hole 111 is set along the first direction, which makes the processing and manufacturing relatively simple and convenient, which is conducive to simplifying the production mold structure and has a good anti-disassembly effect. It is understood that in some other embodiments, the hole axis direction of the first insertion hole 111 can also be other directions, and those skilled in the art can choose according to actual needs.

[0040] Specifically, the groove wall of the first groove 113 is provided with reinforcing ribs, and the groove wall of the second groove 122 is provided with reinforcing ribs, which can improve the structural strength of the clamping cavity and increase the difficulty of the pipe clamp being destructively disassembled.

[0041] It should be understood that the anti-disassembly protection referred to in this application for pipe clamps refers to the protection against complete disassembly. In reality, users can still destructively disassemble the pipe clamps by means of force.
