Description

Anti-loose positioning device

This creation is about a locking element used in processing equipment, especially an anti-loose positioning device that can avoid the internal parts of processing equipment.

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, due to the compact and complex internal structure of large-scale processing equipment and machinery, it is often easy to interfere with long screws, so it is impossible to use longer screws for locking, and shorter screws have limited locking capacity, and at the same time have The shortcomings of loose vibration during operation.

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 anti-loose positioning device includes: a first locking element with a polygonal groove on its top surface, the first locking element provides a locking hole for locking a processing device Middle; and a second locking element, which includes a nut portion, a stud portion and a through hole, the bottom surface of the nut portion is integrally formed with the stud portion, the through hole is provided in the nut portion And the inside of the stud portion communicates with the outside, the second locking element provides locking in the locking hole, so that the stud portion is located above the first locking element, so that the through hole corresponds to the groove , And the diameter of the stud portion is larger than the first locking element.

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 figure. The new anti-loose positioning device includes:

A first locking element 10 is provided with a polygonal groove 11 on the top surface, and the groove 11 is hexagonal.

A second locking element 20 includes a nut portion 21, a stud portion 22 and a through hole 23, the bottom surface of the nut portion 21 is integrally formed with the stud portion 22, the through hole 23 is provided in The nut portion 21 and the stud portion 22 are inside and communicate with the outside, and the diameter of the stud portion 22 is larger than the first locking element 10.

The first locking element 10 is provided with a first external thread 111, the stud portion 22 has a second external thread 221, the pitch of the first external thread 111 is greater than the pitch of the second external thread 221.

Please refer to the second picture to the fourth picture, the use method of the new anti-loose positioning device is:

The first locking element 10 is locked in a lock hole 31 of a processing device 40 with an allen wrench 30, and then the second locking element 20 is locked on the lock by the force of the nut portion 21 with another wrench In the hole 31, the stud portion 22 is located above the first locking element 10, so that the through-hole 23 and the groove 11 are correspondingly communicated, characterized in that since the through-hole 23 is in correspondence with the groove 11, Therefore, when the second locking element 20 is locked, the Allen key can fix or lock the first locking element 10 through the through hole 23 without interfering with the locking of the second locking element 20.

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.
