Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline connection, in particular to a fastener. Background Art

[0002] In the prior art, after searching, it was found that a Chinese patent disclosed "a special pipe fastener", and its announcement number is "CN111998162B". This patent mainly benefits from the fact that the two crossed sliding rods are fixedly connected by a connecting plate, thereby effectively utilizing the connecting plate to fix the distance between the sliding rods, and then the clamping plate and the sliding rod fixed between the pipe change from sliding to rotation when sliding in the sliding groove. On the one hand, compared with the left and right sliding to offset the vibration, the rotation method can effectively diffuse the force conduction in multiple directions, thereby accelerating the consumption rate of vibration energy, and effectively and quickly reducing the vibration frequency of the pipe. At the same time, the process of translational sliding causes a large deformation stress to the pipe, which easily leads to pipe breakage. The rotation method applies stress to the pipe in multiple directions, avoiding stress concentration on the pipe, thereby causing pipe rupture and reducing the service life of the pipe.

[0003] However, this device uses a method of rotating multiple connecting bolts and using the cooperation of the bolts and the clamping plate to fix the pipe. This fixing method requires the operator to manually use professional tools to rotate multiple bolts one by one to ensure the clamping and fixation of the pipe. The entire operation process is relatively cumbersome and time-consuming. It takes a long time to tighten the bolts, which to a certain extent affects the efficiency of the pipe connection.

The outer wall of the fixing ring 1 is fixedly connected to two receiving blocks 211, and the sides of the two receiving blocks 211 that are away from each other are fixedly connected to the first connecting columns 212. The outer walls of the two first connecting columns 212 are rotatably connected to two connecting rods 213. The sides of the plurality of first fixing blocks 22 and the second fixing blocks 29 that are away from each other are fixedly connected to the second connecting columns 214. The left and right ends of the plurality of connecting rods 213 are rotatably connected to the outer walls of the plurality of second connecting columns 214.

[0029] By setting up the fixing mechanism 2, the elasticity of the spring 26 is utilized. The staff can drive the clamping arc plates 21 on the clamping arc plates 21 to contact the second fixing block 29 by flipping the connecting rod 213, clamping the pipeline in the clamping arc plates 21, and turning the dial button 27 to drive the clamping block 28 to be clamped into the inner wall of the second fixing block 29 to complete the fixed clamping of the pipeline.

[0030] The connecting mechanism 3 includes a limit assembly and a connecting assembly. The limit assembly includes a sealing ring 31 arranged on the right side of the fixing ring 1. A number of limit grooves 32 are opened on the right side of the fixing ring 1. The inner walls of the number of limit grooves 32 are all slidably connected to the limit blocks 33. The bottom surface of the sealing ring 31 is fixedly connected with a sealing ring 34. The outer wall of the sealing ring 34 is rotatably connected to the inner wall of the fixing ring 1.

[0032] A specific application of this embodiment is as follows: by setting the fixing mechanism 2, the staff first inserts the two pipes into the connecting grooves 35 of the fixing ring 1 and the sealing ring 31, and after the connection is limited by the connecting mechanism 3, the two connecting rods 213 are driven to flip around the first connecting column 212, and the second connecting column 214 drives the plurality of clamping arc plates 21 to contact each other. The staff only needs to apply a little force to compress the spring 26 so that the clamping block 28 is stuck on the inner wall of the second fixing block 29, completing the fixation between the two clamping arc plates 21 and clamping the pipe. When the staff needs to separate the two clamping arc plates 21, they can drive the slider 25 to slide on the guide rod 24 by toggling the dial button 27 to compress the guide rod 24. At this time, the slider 25 drives the clamping block 28 to slide on the inner wall of the second fixing block 29. After the contact is limited, The flipping connecting rod 213 drives the several clamping arc plates 21 away from each other, disengaging the blocking block 28 from the second fixed block 29, completing the unclamping and loosening the pipe. The slide groove 23 is provided to facilitate the sliding of the slider 25 and the compression of the guide rod 24, wherein several grooves 210 are provided in the clamping arc plate 21 to increase the friction force, realizing the elasticity of the spring 26. The staff can drive the clamping arc plates 21 on the several clamping arc plates 21 to contact the second fixed block 29 by flipping the connecting rod 213, clamping the pipe in the several clamping arc plates 21, and toggle the dial button 27 to drive the blocking block 28 to be stuck on the inner wall of the second fixed block 29, completing the fixed clamping of the pipe. The operation is simple and quick, without the need to use other auxiliary tools, making it convenient for personnel to quickly tighten the pipe and improve efficiency.

[0033] When the pipe is inserted into the connecting groove 35, the staff can fix the fixing ring 1 and the sealing ring 31 on the two pipes respectively through the fixing holes 36, and drive the limiting blocks 33 to slide into the limiting groove 32 through the sealing ring 31. Then, the sealing ring 31 is rotated so that the limiting blocks 33 are limited by the limiting groove 32. Then, the fixing mechanism 2 is cooperated to fix the two pipes to each other to ensure a tight connection between the two pipes. A sealing ring 34 is provided on the sealing ring 31 to seal the connection between the fixing ring 1 and the sealing ring 31 to avoid leakage when the pipe is connected to transport materials. The staff can drive the limiting blocks 33 to slide into the limiting groove 32 for limited connection by rotating the sealing ring 31, and cooperate with the fixing mechanism 2 to further tighten the pipe connection end. At the same time, a sealing ring 34 is provided to seal the connection between the fixing ring 1 and the sealing ring 31, thereby ensuring the sealing of the pipe connection and further improving the practicality of the device.
