DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] The embodiment of the present application discloses a pipe clamp for pipelines with an improved structure. Figure 1 , Figure 2 A pipe clamp for pipelines with an improved structure includes a first assembly shell 1, a second assembly shell 2 is fixedly connected to one side of the first assembly shell 1, and the first assembly shell 1 and the second assembly shell 2 are rectangular structures. A moving block 3 is fixedly connected to one side of the first assembly shell 1, and a moving component 4 for driving the moving block 3 to move is arranged inside the first assembly shell 1. The moving block 3 is arranged opposite to the second assembly shell 2, and a clamping device 5 is arranged between the second assembly shell 2 and the moving block 3. The moving component 4 can drive the moving block 3 to move, thereby adjusting the opening size of the clamping device 5. A quick-release limit component 6 is arranged at the position of the moving block 3 and the second assembly shell 2 relative to the clamping device 5. The quick-release limit component 6 can quickly release and fix the clamping device 5, so as to facilitate the operator to replace the clamping device 5.

[0029] The first moving block 3 and the second moving block 3 are block structures, and the first moving block 3 and the second moving block 3 are fixedly connected. A handle 7 is fixedly connected to the side of the second moving block 3 away from the clamping device 5, and the edge of the handle 7 is chamfered for easy grasping. When the staff grasps the handle 7, there will be no burrs on the surface due to the chamfered edge, and they will not feel uncomfortable when holding it.

[0030] Reference Figure 2 , Figure 3 The moving component 4 includes a linkage block 41 located inside the first assembly shell 1. A mounting groove 11 is opened inside the first assembly shell 1 at a position relative to the linkage block 41. The linkage block 41 is located inside the mounting groove 11 and is slidably connected to the first assembly shell 1. One end of the linkage block 41 extends from the inside of the mounting groove 11 and is fixedly connected to the moving block 3.

[0031] A transmission screw 42 is horizontally arranged inside the first assembly shell 1. The axial direction of the transmission screw 42 is arranged along the opening and closing direction of the clamping device 5, and the transmission screw 42 is threadedly connected to the linkage block 41. When the transmission screw 42 rotates, it drives the linkage block 41 to move along the axial direction of the transmission screw 42, and then drives the moving block 3 to move along the axial direction of the transmission screw 42, that is, the opening and closing direction of the clamping device 5, driving the clamping device 5 to open and close.

[0032] The end of the transmission screw 42 away from the linkage block 41 is coaxially fixedly connected with a driven bevel gear 43, and one end of the driven bevel gear 43 is meshingly connected with a driving bevel gear 44. A driving motor 45 is fixedly connected to the inside of the first assembly shell 1 at a position relative to the driving bevel gear 44, and the motor shaft of the driving motor 45 is coaxial with the driving bevel gear 44 and relatively fixedly connected.

[0033] Start the driving motor 45, drive the output shaft of the driving motor 45 to drive the active bevel gear 44 to rotate, the surface teeth of the active bevel gear 44 contact the surface teeth of the driven bevel gear 43, drive the transmission screw 42 to rotate, the surface of the transmission screw 42 contacts the inner wall of the linkage block 41, move or retract the linkage block 41 into the first assembly shell 1, drive the moving block 3 to approach or move away from the first assembly shell 1, and clamp pipes of different sizes.

[0034] A guide block 411 is fixedly connected to the side wall of the linkage block 41, and a guide groove 16 is provided inside the first assembly shell 1 at a position relative to the guide block 411. The opening direction of the guide groove 16 is set along the axial direction of the transmission screw 42, and the guide block 411 is located inside the guide groove 16 and slides relatively. When the linkage block 41 moves under the drive of the transmission screw 42, the guide block 411 can move inside the guide groove 16, ensuring that the linkage block 41 horizontally enters or moves out of the first assembly shell 1. During the movement of the linkage block 41, no deviation occurs, thereby improving the stability of the movement of the linkage block 41.

[0035] Reference Figure 2 , Figure 4 The clamping device 5 includes a first clamping block 51 sleeved on the side of the moving block 3 close to the second assembly shell 2, and a second clamping block 52 sleeved on the position of the second assembly shell 2 close to the moving block 3. The first clamping block 51 and the second clamping block 52 are arranged opposite to each other. When the moving block 3 moves toward the side close to the second assembly shell 2, the side wall of the first clamping block 51 close to the second clamping block 52 abuts against the side wall of the second clamping block 52 close to the first clamping block 51.

[0036] A trapezoidal groove 53 is provided on one side wall of the first clamping block 51 close to the second clamping block 52 and one side wall of the second clamping block 52 close to the first clamping block 51, and the trapezoidal grooves 53 provided on the first clamping block 51 and the second clamping block 52 are staggered. When the first clamping block 51 and the second clamping block 52 are fitted together, the trapezoidal groove 53 on the first clamping block 51 and the trapezoidal groove 53 on the second clamping block 52 can be relatively meshed. The trapezoidal grooves 53 provided improve the clamping effect of the first clamping block 51 and the second clamping block 52 on the pipe.

[0037] The quick-release limiter assembly 6 includes a first limiter hole 61 formed on the moving block 3 and the second assembly shell 2. The first limiter hole 61 is formed vertically and two are formed opposite to each other along the width direction. A second limiter hole 62 is formed at a position of the side wall of the first clamping block 51 and the second clamping block 52 relative to the first limiter hole 61. The second limiter hole 62 completely penetrates the first clamping block 51 and the second clamping block 52.

[0038] A limiting block 63 is vertically slidably connected inside the first limiting hole 61, and a return spring 64 is arranged between the limiting block 63 and the bottom of the first limiting hole 61, the top end of the return spring 64 is fixedly connected to the limiting block 63, and the bottom end of the return spring 64 is fixedly connected to the bottom of the first limiting hole 61.

[0039] When the return spring 64 is fully compressed, the limit block 63 can be completely located inside the first limit hole 61. When the return spring 64 is in a free state, the limit block 63 extends from the inside of the first limit hole 61, and the limit block 63 extends into the inside of the second limit hole 62 to fix the first clamping block 51 and the second clamping block 52.

[0040] The limit block 63 is pressed into the first limit hole 61, and the limit block 63 squeezes the return spring 64 to contract. The first limit hole 61 and the second limit hole 62 are aligned, and the return spring 64 is reset and opened, and the limit block 63 is moved out of the first limit hole 61, and the limit block 63 enters the second limit hole 62, and the clamping block 4 is firmly connected with the second assembly shell 2 and the moving block 3.

[0041] In some embodiments, the first limiting hole 61, the second limiting hole 62 and the limiting block 63 are designed in an equilateral hexagon to ensure that the position of the limiting block 63 will not shift when it enters the first limiting hole 61 or the second limiting hole 62. At the same time, when the limiting block 63 enters the second limiting hole 62, the clamping block will not shake, thereby ensuring the stability of the connection between the clamping block and the second assembly shell 2 and the moving block 3.

[0042] The first assembly shell 1 and the second assembly shell 2 are made of stainless steel material to extend the service life. The stainless steel material has high physical strength and stable chemical properties. When the first assembly shell 1 and the second assembly shell 2 are squeezed and collided, the surface will not be easily damaged. After long-term use, no rust will be left on the surface of the first assembly shell 1 and the second assembly shell 2, preventing the first assembly shell 1 and the second assembly shell 2 from being damaged due to rust, thereby extending the service life of the first assembly shell 1 and the second assembly shell 2.
