Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe clamp technology, specifically to a pipe clamp with a self-locking function to prevent loosening. Background Technology
[0002] Pipe clamps are tools used to secure and connect pipes, preventing them from moving or vibrating, and ensuring the stability and safety of piping systems. Pipe clamps play a vital role in industries such as manufacturing, construction, plumbing, and electrical systems, and are key components in ensuring the stability and safety of piping systems.
[0003] Pipe clamps consist of a locking assembly and a retaining ring. The locking assembly is usually a screw and a nut. In use, the retaining ring is placed on the pipe, and then the screw and nut of the locking assembly are used to fix the retaining ring on the pipe. At this time, the retaining ring plays a role in fixing and stabilizing the pipe.
[0004] Regarding the above technical conditions, there is also a drawback: the nut and screw are fixed to the pipe by means of threaded connection, but the nut is prone to loosening during use.
[0005] Based on this, this utility model designs an anti-loosening pipe clamp with self-locking function to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a self-locking anti-loosening pipe clamp to solve the above-mentioned technical problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-locking anti-loosening pipe clamp, comprising a fixing ring, a screw, and a nut. The fixing ring has a fixing hole, the screw is inserted into the fixing hole, the nut is connected to the screw, and a fixing plate is rotatably mounted on the nut. Two fixing hooks are mirror-arranged on the fixing plate, and the fixing hooks abut against the fixing ring. The fixing ring is clamped between the fixing plate and the fixing hooks. A washer is fitted onto the screw, and the washer abuts against the fixing ring. The fixing plate is located between the nut and the washer.
[0008] Preferably, the gasket is a spring gasket.
[0009] Preferably, the nut has a rotating groove, and a rotating ring is fixedly disposed on the fixing plate, the rotating ring being inserted into the rotating groove.
[0010] Preferably, the opening of the rotating groove is wide.
[0011] Preferably, the fixing hook is designed with a closed end.
[0012] Preferably, a limiting groove is provided on the fixing ring, and the fixing hook abuts against the limiting groove.
[0013] Preferably, the fixing hook is integrally formed with the fixing plate, and the fixing plate is made of an elastic material.
[0014] In summary, this application has the following beneficial technical effects: In use, the retaining ring is fitted onto the pipe, the screw is inserted into the fixing hole, and the washer, fixing plate, and nut are sequentially fitted onto the screw. External force is used to open the fixing hook, causing it to press against the limiting groove. Finally, the nut is tightened by thread, causing the washer to press against the retaining ring, the fixing plate to press against the washer, and the nut to press against the fixing plate. The retaining ring is locked onto the pipe, resulting in a tight connection between the retaining ring and the pipe. Because the washer is a spring washer, and a spring washer is a type of elastic compression washer, and the fixing plate is made of elastic material, after the nut is tightened, both the washer and the fixing plate will generate action and reaction forces. Under the action of these two forces, the connection between the threads in the nut and the threads on the screw becomes tighter, making the nut less prone to loosening, thus achieving the effect of preventing the pipe clamp nut from loosening.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0024] A self-locking anti-loosening pipe clamp includes a fixing ring 1, a screw 3, and a nut 4. The fixing ring 1 has a fixing hole 8, the screw 3 is inserted into the fixing hole 8, and the nut 4 is connected to the screw 3. The nut 4 is rotatably connected to a fixing plate 2, and two fixing hooks 5 are fixedly installed on the fixing plate 2. The fixing hooks 5 are mirror images of each other on the fixing plate 2, and they abut against the fixing ring 1, clamping the fixing ring 1 between the fixing plate 2 and the fixing hooks 5. A washer 7 is fitted on the screw 3, and the fixing plate 2 is located between the washer 7 and the nut 4.
[0025] In use, the retaining ring 1 is fitted onto the pipe, and the nut 4 is tightened by thread. One end of the screw 3 abuts against the retaining ring 1, the nut 4 abuts against the retaining plate 2, the retaining plate 2 abuts against the washer 7, and the washer 7 abuts against the retaining ring 1. The retaining plate 2 is clamped between the washer 7 and the nut 4, and the retaining hook 5 hooks onto the retaining ring 1. With the combined action of the retaining nut 4 and the washer 7, the nut 4 is not easy to loosen; with the action of the retaining plate 2 and the retaining hook 5, the retaining ring 1 is locked more firmly, and the connection between the retaining ring 1 and the pipe is tighter.
[0026] Washer 7 is a spring washer 7, which is an elastic compression washer. When the thread is tightened on nut 4, washer 7 is compressed. Washer 7 generates action force and reaction force. Under the action of the two forces, the thread on nut 4 is more tightly connected to the thread on screw 3, and nut 4 is less likely to loosen.
[0027] The nut 4 has a rotating groove 9, and a rotating ring is fixedly mounted on the fixing plate 2. The rotating ring is inserted into the rotating groove 9, which has a wide opening to facilitate insertion. First, the fixing plate 2 is placed on the screw 3, so that the fixing hook 5 hooks the fixing ring 1. As the nut 4 is tightened, the rotating ring is inserted into the rotating groove 9. The rotating ring and the rotating groove 9 increase the stability of the connection between the fixing plate 2 and the nut 4.
[0028] A limiting groove 6 is formed on the side of the retaining ring 1 away from the nut 4. The retaining hook 5 is pressed against the limiting groove 6, which increases the connection stability between the retaining hook 5 and the retaining ring 1. The retaining hook 5 and the retaining plate 2 are integrally formed. The retaining plate 2 is made of elastic material, and the retaining hook 5 is designed with a constricted opening. In use, the retaining plate 2 is sleeved on the screw 3, and then the retaining hook 5 is opened by external force, so that it is pressed against the limiting groove 6. The retaining ring 1 is clamped between the retaining hook 5 and the retaining plate 2, which further increases the locking force on the retaining ring 1.
[0029] The implementation principle of this embodiment is as follows: In use, the fixing ring 1 is fitted onto the pipe, the screw 3 is inserted into the fixing hole 8, and the washer 7, fixing plate 2, and nut 4 are fitted onto the screw 3 in sequence. External force is used to pry open the fixing hook 5, causing it to abut against the limiting groove 6. Finally, the nut 4 is tightened by thread, causing the washer 7 to abut against the fixing ring 1, the fixing plate 2 to abut against the washer 7, and the nut 4 to abut against the fixing plate 2. The fixing ring 1 is locked onto the pipe, and the connection between the fixing ring 1 and the pipe is tight. Because the washer 7 is a spring washer 7, and the spring washer 7 is an elastic compression washer, and the fixing plate 2 is made of elastic material, after the nut 4 is tightened, both the washer 7 and the fixing plate 2 will generate action and reaction forces. Under the action of these two forces, the connection between the thread in the nut 4 and the thread on the screw 3 becomes tighter, making the nut 4 less prone to loosening, thus achieving the effect of preventing the nut 4 of the pipe clamp from loosening.
