Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pipe clamps, and particularly relates to an adjustable pipe clamp. BACKGROUND

[0002] A pipe clamp is a fastening device used to fix the position of a pipe or a pipe fitting, and is mainly used for fixing water pipes, gas pipes and metal pipes. Two pipe clamps (an upper pipe clamp and a lower pipe clamp) of the same shape are tightly held on a pipe, and the pipe is clamped by bolts between the pipe clamps.

[0003] Patent No. CN219102228U discloses an adjustable pipe clamp, which comprises an upper clamp and a lower clamp. The middle of the upper clamp is provided with an upper arc-shaped part, and the two sides of the upper clamp are provided with upper connecting parts. The middle of the lower clamp is provided with a lower arc-shaped part, and the two ends of the lower clamp are provided with lower connecting parts. A pipe fitting is installed between the upper arc-shaped part and the lower arc-shaped part. The bottom of the upper connecting part is provided with a stud, and the lower connecting part is provided with a through hole at a position matched with the stud. A compression bolt is transversely installed on the stud.

[0004] The above patent can clamp and fix pipes of different diameters by adjusting the distance between the upper clamp and the lower clamp. However, during clamping, the clamp relies on fasteners such as studs and compression bolts with bolts for fixation. Although the adjustment and fastening effect can be achieved, the threads may be worn after multiple uses, resulting in ineffective fastening. Moreover, the studs cannot be replaced, and the overall replacement cost is high. Therefore, improvement is needed. SUMMARY

[0005] The application aims to provide an adjustable pipe clamp that can solve the above problems.

[0006] The application aims to provide an adjustable pipe clamp, which comprises:

[0007] The upper clamp ring is provided with first extension parts on both sides.

[0008] The lower clamp ring is provided with second extension parts on both sides.

[0009] The fastening and adjusting part is arranged on the upper clamp ring and the lower clamp ring and is used to fix the upper clamp ring and the lower clamp ring and adjust the distance between the upper clamp ring and the lower clamp ring.

[0010] The adjusting fastener is arranged on both sides of the upper clamp ring and the lower clamp ring.

[0011] The adjustable pipe clamp has the advantages that the traditional pipe clamp relies on fasteners such as studs and compression bolts with bolts for fixing, and these fasteners are prone to failure in fastening effect due to thread wear after multiple uses. The adjustable pipe clamp avoids this problem through the design of the fastening adjusting piece. The fastening adjusting piece not only has the functions of adjusting and fastening, but also can maintain a high fastening effect in long-term use and is not prone to failure due to wear. Once the stud fixing part of the traditional pipe clamp is damaged, the entire pipe clamp often needs to be replaced, resulting in high cost. The design of the fastening adjusting piece of the adjustable pipe clamp allows individual replacement when necessary, without the need to replace the entire pipe clamp, thereby greatly reducing the replacement cost.

[0012] The fastening adjusting piece is arranged on the upper and lower clamping rings and arranged on both sides of the upper and lower clamping rings, so that the pipe clamp can conveniently adjust the distance between the upper and lower clamping rings, thereby adapting to pipes of different diameters. At the same time, the bilateral fastening adjusting piece also enhances the stability and clamping force of the pipe clamp. The installation and maintenance process of the adjustable pipe clamp is relatively simple. The user only needs to adjust the fastening adjusting piece to achieve clamping and fixing of the pipe, without the need for complex operations or tools.

[0013] Further, the fastening adjusting piece comprises:

[0014] The first fastener comprises a connecting portion arranged on the first extension portion and a first fastening rod sequentially penetrating the second extension portion, the first extension portion and being threadedly connected with the connecting portion;

[0015] The second fastener is arranged on the first fastening rod and used for compressing the side wall of the pipe body.

[0016] The threads of the first fastening rod are not in contact with the first extension portion and the second extension portion when the first fastening rod penetrates the first extension portion and the second extension portion, and the first fastener is arranged in two groups, which are symmetrically arranged on both sides of the second fastener.

[0017] The first fastener comprises a connecting portion arranged on the first extension portion and a first fastening rod sequentially penetrating the second extension portion, the first extension portion and being threadedly connected with the connecting portion. The first fastening rod is designed as a rod-shaped part with external threads, which can penetrate the reserved holes of the second extension portion and the first extension portion and be threadedly connected with the connecting portion. By rotating the first fastening rod, the thread connection between the first fastening rod and the connecting portion can be gradually tightened, so as to compress the upper clamping ring and the lower clamping ring together and achieve clamping of the pipe. Since the threads of the first fastening rod are not in direct contact with the first extension portion and the second extension portion, the influence of thread wear on the performance of the pipe clamp is avoided, and the service life of the pipe clamp is prolonged. The first fastener is arranged in two groups and symmetrically arranged on both sides of the second fastener, which enhances the stability and clamping force of the pipe clamp and ensures that the pipe does not shake or fall off during clamping.

[0018] The second fastener is arranged on the first fastening rod and is used to press the side wall of the pipe body, which can directly act on the pipe side wall and provide additional clamping force. It can increase the clamping area of the pipe and improve the clamping stability. By adjusting the pressing degree of the second fastener, the position and stability of the pipe in the pipe clamp can be further controlled. The second fastener is used in cooperation with the first fastener to achieve comprehensive clamping and fixing of the pipe, ensuring that the pipe will not be damaged or displaced during transportation, installation and use.

[0019] Further, the connecting part is rectangular in shape, and the surface is provided with a threaded hole matched with the first fastening rod, and the first extension part is provided with a sliding clamping groove matched with the connecting part.

[0020] The connecting part is designed in a rectangular shape, which not only enhances the structural strength of the connecting part, but also makes it more compatible with the sliding clamping groove of the first extension part, ensuring the stability and reliability of the connection. The surface of the connecting part is provided with a threaded hole matched with the first fastening rod, and by rotating the first fastening rod, it can be gradually tightened and tightly matched with the threaded hole of the connecting part, thereby providing sufficient clamping force. The first extension part is provided with a sliding clamping groove matched with the connecting part, which can ensure that the connecting part will not shake or fall off after being inserted into the clamping groove. The connecting part and the first extension part are connected in a plug-in manner, greatly simplifying the installation and disassembly process. Users do not need to use complex tools or perform tedious operations to complete the installation or disassembly work. At the same time, it allows the connecting part to be replaced individually when necessary, without the need to replace the entire pipe clamp. This not only reduces the replacement cost, but also improves the maintainability and service life of the pipe clamp.

[0021] Further, the second extension part is provided with an extension protrusion, the extension protrusion is provided with a first through hole for the first fastening rod to pass through and penetrate the second extension part, the diameter of the first through hole is greater than the diameter of the first fastening rod, and the extension protrusion is provided with a protective cover, and the protective cover is provided with a second through hole with the same diameter as the first fastening rod.

[0022] The extension protrusion is arranged on the second extension part, providing a stable support point for the first fastening rod, so that it can smoothly pass through the second extension part and be screwed with the connecting part. The first through hole is arranged on the extension protrusion, used for the first fastening rod to pass through and penetrate the second extension part. The diameter of the first through hole is designed to be slightly larger than the diameter of the first fastening rod, to ensure that the first fastening rod can pass through easily, while maintaining a certain fit tightness. It not only avoids the wear and tear caused by thread contact, but also prevents the problem of looseness caused by too loose fit. The protective cover is arranged on the extension protrusion, used to cover and protect the first through hole and the first fastening rod passing through it, playing a protective role, avoiding direct contact between the first fastening rod and the extension protrusion. The second through hole is arranged on the protective cover, used to cooperate with the first fastening rod, and its diameter is the same as that of the first fastening rod, to ensure that the protective cover can be tightly fitted on the first fastening rod, preventing it from loosening or falling off.

[0023] The arrangement of the extension protrusion and the first through hole enhances the stability and fastening effect of the pipe clamp, so that the first fastening rod can be firmly fixed between the connecting part and the second extension part. At the same time, it also improves the durability of the pipe clamp, so that the first fastening rod will not be subjected to excessive friction or wear when passing through the first through hole. The arrangement of the protective cover can prolong the service life and ensure the stability of the fastening.

[0024] Further, the second fastener comprises:

[0025] The mounting seat is arranged with a threaded hole in the center, and connecting seats are arranged on both sides, which are screwed with the first fastening rod;

[0026] The second fastening rod is screwed with the threaded hole in the center of the mounting seat, and the end is provided with a pressing plate in contact with the pipe body;

[0027] The connecting seat is provided with a spring between the first extension part and the second extension part, which is sleeved on the second fastening rod.

[0028] The mounting seat is the main part of the second fastener, with a threaded hole in the center for screwing with the second fastening rod. The connecting seats are arranged on both sides of the mounting seat, which are screwed with the first fastening rod, so as to fix the second fastener on the first fastening rod. The second fastening rod is a rod-shaped part with external threads, which can be screwed with the threaded hole in the center of the mounting seat. The end of the second fastening rod is provided with a pressing plate, which can directly act on the pipe side wall to provide additional clamping force. The spring is arranged between the connecting seat and the first extension part and the second extension part, and is sleeved on the second fastening rod. The existence of the spring not only enhances the stability of the second fastener, but also provides pre-tightening force when the first fastening rod is tightened, and improves the disassembly efficiency when disassembled.

[0029] By rotating the second fastening rod, it can be gradually tightened and closely matched with the threaded hole of the mounting seat, so as to exert additional clamping force on the side wall of the pipeline through the pressing plate. Make the pipe clamp can hold the pipeline more firmly, prevent from shaking or falling off.

[0030] Further, the first fastening rod and the second fastening rod each include a rod part and a hand screw part arranged on the rod part.

[0031] The hand screw part is shaped to be easy to hold and rotate, facilitating the user to directly operate by hand. The design of the hand screw part enables the user to easily and quickly rotate the fastening rod, realizing clamping or loosening operation. This greatly improves the usability and working efficiency of the pipe clamp.

Once the stud fixation part of a traditional pipe clamp is damaged, the entire pipe clamp often needs to be replaced, resulting in high costs. The design of the fastening adjustment member of the adjustable pipe clamp allows for individual replacement when necessary, eliminating the need to replace the entire pipe clamp, thereby significantly reducing replacement costs.

[0051] The fastening adjustment member is arranged on the upper clamping ring 100 and the lower clamping ring 200, and is arranged on both sides of the upper clamping ring 100 and the lower clamping ring 200. This allows the pipe clamp to easily adjust the distance between the upper clamping ring 100 and the lower clamping ring 200, thereby adapting to pipes of different diameters. At the same time, the bilateral fastening adjustment members also enhance the stability and clamping force of the pipe clamp. The installation and maintenance process of the adjustable pipe clamp is relatively simple.

Users do not need to use complex tools or perform tedious operations to complete the installation or disassembly work. At the same time, it allows the connecting portion 310 to be replaced individually when necessary, without the need to replace the entire pipe clamp. This not only reduces the replacement cost, but also improves the maintainability and service life of the pipe clamp.
