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

[0024] Such as figure 1 , 2 As shown, 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 rotatably connected to the front end of the bolt 11, and the surfaces of the bolt 11 and the anti-slip pressure plate 12 are respectively provided with opposite first One anti-reverse helical gear and the second anti-reverse helical gear, the first anti-reverse helical gear and the second anti-reverse helical gear respectively have a plurality of first anti-reverse helical teeth 111 and several second anti-reverse helical teeth 121 Composition, the first anti-reverse helical tooth 111 and the second anti-reverse helical tooth 121 can mesh with each other, the first anti-reverse helical tooth 111 is inclined in the direction opposite to the tightening direction of the bolt 11, and the direction of the second anti-reverse helical tooth 121 is the same as The direction of the first anti-reverse helical teet...

Embodiment 2

[0030] On the basis of the technical solution of embodiment 1, the anti-skid structure is improved in another way:

[0031] Such as Figure 5 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. Apply the anti-loosening bolt assembly 1 to a kind of anti-loosening clamping mechanism, such as Figure 6 shown.

Embodiment 3

[0033] On the basis of the technical solution of embodiment 1, the bolt is further improved:

[0034] Such as Figure 7 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.

[0035]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 tor...

Abstract

The invention relates to the field of electric power tools, in particular to an anti-loose bolt assembly. The anti-loose bolt assembly comprises a bolt and an antiskid pressing plate. The back face ofthe antiskid pressing plate is rotatably connected with the front end of the bolt, and first non-return inclined teeth and second non-return inclined teeth which can be engaged mutually are arrangedon the mutually attached surfaces of the bolt and the antiskid pressing plate correspondingly; the first non-return inclined teeth are inclined in the direction opposite to the bolt screwing direction, the direction of the second non-return inclined teeth is opposite to the direction of the first non-return inclined teeth, and thus the bolt is limited to rotate reversely relative to the antiskid pressing plate; and a jacking-pressing part used for jacking and pressing an object is arranged on the front face of the antiskid pressing plate, and an antiskid structure is arranged on the jacking-pressing part so as to limit the antiskid pressing plate to rotate reversely relative to the jacked and pressed object. The anti-loose bolt assembly has the beneficial effects that the antiskid structure limits the antiskid pressing plate to rotate reversely relative to the pressed object, the bolt cannot rotate reversely relative to the antiskid pressing plate through engagement of the second non-return inclined teeth and the first non-return inclined teeth, and thus it is ensured that the bolt is not loosened.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to an anti-loosening bolt assembly. Background technique [0002] In the field of power tools, the clamping mechanism used to fix the power tool on the cable to perform maintenance operations such as grounding and electrical inspection on the cable usually uses bolts that match the clamping mechanism body to press the cable against the clamping mechanism body , so as to realize 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 order to solve the above problems, the task of the present invention is to p...
