Problems solved by technology

However, because the bolt connection will loosen after a long time, especially in the environment with a lot of grease or high-frequency vibration, the bolt connection is more likely to loosen, which will cause the clamping mechanism to clamp the cable unstable or even loosen, causing the corresponding electric power tool not working

Embodiment 1

[0023] Such as Figure 1-2 As shown, an anti-loosening clamp mechanism includes an anti-loosening bolt assembly 1 and a thread clamping mechanism body 2. The anti-loosening bolt assembly 1 includes a bolt 11 and an anti-slip pressure plate 12. The back of the anti-slip pressure plate 12 is rotatable with the front end of the bolt 11. connected, and the surface of the bolt 11 and the anti-skid pressure plate 12 are respectively provided with the first anti-backlash helical gear and the second anti-backlash helical gear, the first anti-backlash helical gear and the second anti-backlash helical gear It consists of a number of first anti-reverse helical teeth 111 and a number of second anti-reverse helical teeth 121, the first anti-reverse helical teeth 111 and the second anti-reverse helical teeth 121 can mesh with each other, and the first anti-reverse helical teeth 111 face The screwing direction of the bolt 11 is inclined in the opposite direction, and the direction of the sec...

Embodiment 2

[0028] On the basis of the technical solution of embodiment 1, the anti-skid structure is improved in another way:

[0029] Such as image 3 As shown, the anti-skid structure is a straight groove structure 123 arranged on the pressing part. The straight groove structure 123 is a concave arc straight groove, so that the surface of the cable can be embedded in it. Pressing against the outer surface of the cable can limit the rotation of the anti-slip pressing plate 12 relative to the cable.

Embodiment 3

[0031] On the basis of the technical solution of embodiment 1, the bolt is further improved:

[0032] Such as Figure 4 As shown, the rear end of the bolt 11 is provided with a first bolt head 112 and a second bolt head 113 in sequence along the axial direction, and a fracture part 114 is provided between the first bolt head 112 and the second bolt head 113, and the fracture part 114 can bear The maximum torque is less than the maximum torque that other parts of the bolt 11 can bear. When the torque that the first bolt head 112 bears is greater than the maximum torque that the fractured part 114 can bear, the fractured part 114 will break so that the first bolt head 112 can be removed from the bolt 11. break away.

[0033] The fractured part 114 is structured as an annular groove 1141 provided on the outer surface of the bolt 11 and an inner hole 1142 provided inside the bolt 11, so that the wall thickness at the fractured part 114 is relatively small and breaks first when to...

Abstract

The invention relates to the field of electric power tools, in particular to an anti-loosing cable clamping mechanism. The anti-loosing cable clamping mechanism comprises a cable clamping mechanism body and an anti-loosing bolt assembly; the anti-loosing bolt assembly comprises a bolt and an anti-slip pressing plate which can be rotatably connected, first check oblique teeth and second check oblique teeth which can be meshed mutually are arranged on the attaching surfaces of the bolt and the anti-slip pressing plate respectively to limit inverse rotation, relative to the anti-slip pressing plate, of the bolt, and an anti-slip structure is arranged on the pressing portion of the anti-slip pressing plate to limit inverse rotation, relative to a pressed cable, of the anti-slip pressing plate;and the cable clamping mechanism body is provided with a static chuck and a threaded hole which are arranged oppositely, the bolt achieves threaded connection with the threaded hole, and the pressingportion of the anti-loosing bolt assembly faces the static chuck to be capable of cooperating with the static chuck to clamp the cable. The anti-loosing cable clamping mechanism has the advantages that the anti-slip structure limits rotation of the anti-slip pressing plate relative to the cable, the bolt cannot inversely rotate relative to the anti-slip pressing plate by means of meshing of the second check oblique teeth and the first check oblique teeth, and then it is guaranteed that the bolt cannot loose.

Description

technical field [0001] The invention relates to the field of power tools, in particular to an anti-loosening clamping mechanism. Background technique [0002] The clamping mechanism is used to fix the power tool on the cable, so as to perform maintenance operations such as grounding and electric inspection on the cable, and is an important part of the power tool. At present, the clamping mechanism usually uses bolts matching the body of the clamping mechanism to press the cable against the body of the clamping mechanism, thereby realizing the fixing of the clamping mechanism and the cable. However, because the bolt connection will loosen after a long time, especially in the environment with a lot of grease or high-frequency vibration, the bolt connection is more likely to loosen, which will cause the clamping mechanism to clamp the cable unstable or even loosen, causing the corresponding electric power Tool doesn't work properly. Contents of the invention [0003] In ord...
