Description

Novel structure nylon self-locking nut closing device

Technical Field

The utility model relates to a nut technical field specifically is a novel structure nylon auto-lock nut binding off device.

Background

Among nut products, the nylon self-locking nut is widely applied due to the self-locking function and the simple structure. The biggest problem of the nylon self-locking nut in the process of being screwed is that the nylon gasket is easy to rotate, and then the problem of difficult assembly and the like occurs. The nylon lock nut realizes the locking performance by means of extrusion friction formed between the nylon sleeve and the bolt, so that when the end face of the nut embedded with the nylon sleeve is compressed, the end face needs to ensure certain pressing force on the nylon sleeve, the pressing force needs to ensure that the nylon sleeve cannot rotate in the nut in the screwing process on one hand, and the nylon sleeve generates proper extrusion force on the bolt to meet the requirement of locking force on the other hand. Therefore, a device for closing the nylon self-locking nut with a novel structure is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel structure nylon auto-lock nut binding off device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel structure nylon auto-lock nut binding off device, includes the fixed block, fixed block below and gag lever post fixed connection, the gag lever post is equipped with first briquetting of assorted, second briquetting and third briquetting, first briquetting, second briquetting and third briquetting all can cup joint on the gag lever post, the gag lever post is kept away from fixed block one side and is equipped with the nut body, nut body upper end is seted up flutedly, the recess is inside to be inlayed there is the nylon ring, the gag lever post is kept away from fixed block one end and is run through nylon ring and threaded rod fixed connection, the threaded rod is equipped with the assorted screw thread with nut body inner wall.

Preferably, the first pressing block is located above the nylon ring, a tapered groove is formed in the middle of the lower portion of the first pressing block, the tapered groove and the axis of the limiting rod are located on the same cross section, and the inclination angle of the tapered groove is 45 degrees.

Preferably, the second pressing block is positioned above the nylon ring, and a downward cambered surface is arranged below the second pressing block.

Preferably, the third pressing block is positioned above the nylon ring, and a plane is arranged below the third pressing block.

Compared with the prior art, the beneficial effects of the utility model are that: this kind of device of novel structure nylon auto-lock nut binding off, the binding off problem of novel structure nylon lock nut behind the embedding nylon cover. The method not only ensures the qualification of the locking performance test after the nut is compressed, but also ensures the quality consistency of the batch closing of the product.
