Description

Wrench type fixing device

This creation relates to a fixing device for a locking element on a processing equipment, especially a wrench-type fixing device capable of fixing two locking elements at the same time, to avoid the loosening of the locking element when the processing equipment is in operation.

The locking of bolts and nuts is a commonly used structure for assembly and fixing of machine parts. It is widely used in various types of processing machines, home appliances, wheel frame assembly, etc. The bolts and nuts are used to clamp different parts by using the thread structure that cooperates In order to achieve the purpose of locking between different parts, the problem often encountered by the conventional knowledge is that after long-term use under a vibrating environment, the nut will loosen, resulting in insufficient clamping force.

In order to solve this problem, various kinds of anti-return nuts and anti-return gaskets are used to prevent the nut from loosening, but the elastic member of the nut of the conventional screw connection assembly to prevent loosening is a built-in structure Once it is damaged or improperly installed, it cannot be known from the external observation, and there is often a problem that the failure cannot be achieved to prevent the nut from loosening. In addition, only when the elastic member is caught in the groove, it has the effect of stopping back. Therefore, the relative position of the nut relative to the bolt (that is, the rotation angle of the nut) is restricted, and the angle of the nut lock can not be adjusted steplessly. That is, it cannot meet the requirement of fine adjustment of the clamping force of the screw lock.

In view of this, how to eliminate the above deficiencies is the technical difficulty that the creator of this case wants to solve; but, the creator of this case is based on years of experience in the relevant industry, after years of painstaking research, trial and error improvement, and finally Successfully developed and completed this case, and enabled the birth of this new model to improve efficiency.

In view of the above-mentioned shortcomings, the new wrench-type fixing device includes: a fixing device body with a positioning hole at one end and a locking groove recessed at the bottom of the other end, the positioning hole provides a corresponding combination of a processing device On a first locking element, the first locking element is rotatably locked by the fixing device body, and when the first locking element is tightly screwed in the processing equipment, the locking groove is locked on the processing equipment A second locking element.

In order to facilitate the description of the content of the new model and the effect that can be achieved, the specific embodiments are listed in conjunction with the drawings. Please refer to the first and second drawings. The new wrench-type fixing device includes:

A fixing device body 10 has a positioning hole 11 at one end, and a locking groove 12 is recessed on the bottom surface of the other end.

The fixing device body 10 is an elongated plate body, the positioning hole 11 has a hexagonal shape, and the locking groove 12 has a concave arc shape.

Please refer to the second to fourth figures. The positioning hole 11 is correspondingly coupled to a first locking element 21 of a processing device 20. The first locking element 21 is a hexagonal bolt.

The fixing device body 10 rotates and locks the first locking element 21. When the first locking element 21 is tightly screwed in the processing device 20, the locking groove 12 is simultaneously locked on a side of the processing device 20 On the second locking element 22.

The second locking element 22 has a nut portion 221 and a stud portion 222. When the first locking element 21 rotates and is tightly screwed in the processing device 20, the locking slot 12 enters And is locked on the stud portion 222 of the second locking element 22.

In other words, the fixing device body 10 is a special tool, which is manufactured according to the distance, shape and size between the first locking element 21 and the second locking element 22 on the processing equipment 20, so the fixing device body 10 can simultaneously fix the first lock The fixing element 21 and the second locking element 22 prevent the first locking element 21 and the second locking element 22 from falling when the processing equipment is in operation.

The above detailed description is a specific description of a feasible embodiment of the new model, but the embodiment is not intended to limit the patent scope of the new model, and any equivalent implementation or change without departing from the spirit of the new art should be included in this case In the scope of patents.
