Description

Tooth lock

This creation relates to a locking element used in processing equipment, especially a tooth-shaped locking element that can prevent the locking element from loosening due to vibration when the processing equipment is operating.

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 shortcomings, the new tooth-shaped locking device includes: a first gear, which has a through hole, the inner wall of the top end of the through hole has an inclined portion, the through hole is sleeved on a first lock On the fixing element, the first locking element includes a nut portion, an adjusting portion and a stud portion, the outer diameter of the adjusting portion is inclined and corresponds to the inclined portion, the first locking element provides a lock Fixed on an external device so that the first gear is in a pivoted state; and a second gear, the center of which has a polygonal through hole, the polygonal through hole is sleeved on a second locking element, and the first gear The two locking elements are locked on the external device and form a loose mesh state with the first gear. After the second locking element is locked, the first locking element is locked again so that the inclined surface is The adjusting portion contacts, and at the same time, the first gear and the second gear form a tight mesh state.

In order to facilitate the description of the content of the new model and the achievable effects, specific embodiments are listed in conjunction with the drawings. Please refer to the first and second figures. The new tooth-shaped locking device includes:

A first gear 10 is provided with a through hole 11, the inner wall of the top end of the through hole 11 has a slanted portion 111, the through hole 11 provides a sleeve on a first locking element 12, the first locking The element 12 includes a nut portion 121, an adjustment portion 122 and a stud portion 123. The outer diameter of the adjustment portion 122 is inclined and corresponds to the inclined portion 111.

A second gear 20 has a polygonal through hole 21 in the center, and the polygonal through hole 21 is sleeved on a second locking element 22, wherein the polygonal through hole 21 is hexagonal, and the second locking element 22 is the external hex screw.

Please refer to the third and fourth figures, the first locking element 12 is provided to be locked on an external device A, so that the first gear 10 is in a pivoted state.

Please refer to the fifth and sixth figures, the second locking element 22 is locked on the external device A, and forms a loose mesh with the first gear 10, when the second locking element 22 is locked Then, the first locking element 12 is locked so that the inclined surface 111 contacts the adjusting portion 122, and at the same time, the first gear 10 and the second gear 20 form a tight mesh state.

Please refer to the seventh figure. In other words, when the second locking element 22 is locked, since the first locking element 12 is not completely locked with the external device A, the first gear 10 will rotate with the second gear 20. After the second locking element 22 is locked, the first locking element 12 is locked again, so that the first gear 10 and the second gear 20 form a tight meshing state, so that it can effectively prevent the vibration caused by the external device during operation. One locking element 12 or the second locking element 22 falls off.

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.
