[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0021] This utility model proposes a quick clamping and disassembly pipe clamp structure, hereinafter referred to as the pipe clamp structure, which solves the problems of cumbersome assembly process, complex structure and difficulty in quick assembly and disassembly of existing pipe clamp structures.

[0022] like Figure 1 and Figure 2 As shown, the quick clamping and disassembly pipe clamp structure includes a fixed clamp 1, a movable clamp 2, and a locking mechanism 3. The fixed clamp 1 is mounted on an external device. The first end of the movable clamp 2 is rotatably connected to the first end of the fixed clamp 1, and the movable clamp 2 can cooperate with the fixed clamp 1 to limit the pipe fitting. The locking mechanism 3 includes an adjusting shaft 3.1 and a self-locking assembly. The adjusting shaft 3.1 is rotatably connected to the second end of the fixed clamp 1. The self-locking assembly is sleeved on the adjusting shaft 3.1 and is adjustablely connected to the adjusting shaft 3.1. The self-locking assembly can limit the second end of the movable clamp 2 between the self-locking assembly and the second end of the fixed clamp 1. A fixed clamp 1 is installed on an external device. The fixed clamp 1 and the movable clamp 2 cooperate to limit the pipe fitting, thus confining the pipe fitting to the external device. When the self-locking component is rotated to approach the fixed clamp 1, the self-locking component abuts against the second end of the movable clamp 2 to limit the second end of the movable clamp 2, ensuring a tight fit between the fixed clamp 1 and the movable clamp 2. When the self-locking component is rotated away from the fixed clamp 1, the second end of the movable clamp 2 loses the restriction of the self-locking component, and the pipe fitting can be removed by opening the movable clamp 2. This utility model has a simple structure, and the quick assembly and disassembly of the pipe clamp structure can be achieved by rotating the self-locking component, which helps to improve the efficiency of assembly and disassembly operations.

[0023] The self-locking assembly includes a self-locking clamp 3.2, a nut shaft 3.3, and a cam block 3.4. The self-locking clamp 3.2 is rotatably connected to the adjusting shaft 3.1 via the nut shaft 3.3. The self-locking clamp 3.2 includes a gripping part 3.2.1 and a wheel part 3.2.2 connected to each other. The wheel part 3.2.2 is eccentrically rotatably connected to the adjusting shaft 3.1 via the nut shaft 3.3. The nut shaft 3.3 is sleeved on the adjusting shaft 3.1 and threadedly connected to the adjusting shaft 3.1. The cam block 3.4 is slidably sleeved on the adjusting shaft 3.1. The cam block 3.4 forms a limiting surface 3.4.1 that matches the contour of the wheel part 3.2.2. The limiting surface 3.4.1 is in rolling contact with the wheel part 3.2.2. When clamping the pipe fitting, flip the movable clamp 2 above the fixed clamp 1 so that the movable clamp 2 and the fixed clamp 1 cooperate to limit the pipe fitting. Then, the operator holds the self-locking clamp 3.2 and drives the nut shaft 3.3 to rotate horizontally, pushing the cam block 3.4 down so that the cam block 3.4 presses against the second end of the movable clamp 2. After ensuring that the pipe fitting is tightly fitted with the movable clamp 2 and the fixed clamp 1, rotate the self-locking clamp 3.2 vertically. The wheel body 3.2.2 rolls relative to the limiting curved surface 3.4.1 of the cam block 3.4, and the wheel body 3.2.2 of the self-locking clamp 3.2... An eccentric cam structure is formed between the cam block 3.4 and the cam block 3.4. The limiting convex surface of the cam block 3.4 can effectively limit the wheel body 3.2.2, thereby realizing the self-locking function to prevent the self-locking clamp 3.2 from jumping out and causing the pipe to loosen. This effectively ensures the clamping effect of the pipe clamp structure. When it is necessary to disassemble the pipe, simply rotate the self-locking clamp 3.2 in the opposite direction along the vertical plane, and then drive the nut shaft 3.3 to rotate in the opposite direction along the horizontal plane to remove the pressure of the cam block 3.4 on the second end of the movable clamp 2. The movable clamp 2 can then be flipped open to remove the pipe clamp. The operation is simple and the disassembly is quick.

[0024] Furthermore, the locking mechanism 3 also includes an elastic element 3.5 and a washer 3.6 sleeved on the adjusting shaft 3.1. The elastic element 3.5 abuts against the cam block 3.4 and the washer 3.6. The washer 3.6 provides a support platform for the elastic element 3.5. When the cam block 3.4 presses against the elastic element 3.5, the elastic element 3.5 can also apply force to the cam block 3.4 to press the cam block 3.4 against the wheel body 3.2.2, ensuring the self-locking effect between the cam block 3.4 and the wheel body 3.2.2. When disassembling the pipe, the cam block 3.4 loses the pressure applied by the wheel body 3.2.2 and is pushed upward by the elastic element 3.5, so that the second end of the movable clamp 2 can quickly disengage from the self-locking assembly, improving the disassembly efficiency.

[0025] Furthermore, the gripping part 3.2.1 forms an arc-shaped surface A1 that matches the contour of the human hand, and the wheel part 3.2.2 forms a first clearance groove B1 for the adjustment shaft 3.1 to pass through. The arc-shaped surface A1 facilitates the operator's grip, improving the convenience of the disassembly and assembly process and accelerating the disassembly and assembly speed; the first clearance groove B1 in the wheel part 3.2.2 effectively prevents interference between the self-locking clamp 3.2 and the adjustment shaft 3.1 during disassembly and assembly, ensuring the efficiency of the disassembly and assembly operation and extending the service life of the clamp structure.

[0026] In this embodiment, the end of the gripping part 3.2.1 away from the wheel body part 3.2.2 is also provided with a protruding structure A2. The protruding structure A2 can prevent the gripping part 3.2.1 from being completely fitted with the movable clamp 2, making it easier for the operator to separate the self-locking clamp 3.2 from the movable clamp 2 to grip the self-locking clamp 3.2.

[0027] Specifically, the movable clamp 2 includes an arc-shaped portion 2.1 and a straight portion 2.2 connected to each other. The arc-shaped portion 2.1 is rotatably connected to the fixed clamp 1, and the straight portion 2.2 forms a second clearance groove 2.2.1 for the adjustment shaft 3.1 and the elastic element 3.5 to pass through. The arc-shaped portion 2.1 of the movable clamp 2 facilitates better cooperation between the movable clamp 2 and the pipe fitting, avoiding damage to the surface of the pipe fitting caused by the movable clamp 2. The straight portion 2.2 is used to abut against the cam block 3.4 to ensure the limiting and locking effect. The second clearance groove 2.2.1 can avoid the adjustment shaft 3.1 and the elastic element 3.5, further ensuring the limiting and locking effect.

[0028] In addition, the quick-clamping and disassembly pipe clamp structure also includes a spring pin 4, which is rotatably connected to the movable clamp 2 via a spring pin 4, and the second end of the fixed clamp 1 is rotatably connected to the adjusting shaft 3.1 via another spring pin 4. In this embodiment, the spring pin 4 is a spring straight groove cylindrical pin with a certain elasticity, so as to facilitate the reset of the movable clamp 2 and the adjusting shaft 3.1 and improve the ease of operation during the disassembly and assembly process.

[0029] In this embodiment, the fixing clamp 1 has a mounting groove 1.1, and a through hole 1.2 is formed in the mounting groove 1.1. The fastener passes through the through hole 1.2 to connect with the external device. The mounting groove 1.1 provides space for the installation of the fastener, avoiding interference between the fastener and the pipe fitting and damage to the pipe fitting. In this embodiment, the fastener is a locking hexagonal head bolt.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
