For this reason, a corresponding technical scheme needs to be designed to solve the existing technical problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bolt-up structure has solved and has fastened because of the large-scale bolt nut of application in large-scale engineering equipment needs large-scale instrument when fastening, and when going out the during operation, the technical problem of the work of the influence equipment that the not hard up problem of bolt leads to can appear, has improved the convenience of using, satisfies the in-service use demand.

In order to achieve the above object, the utility model provides a following technical scheme: including being fastened connecting piece, first bolt and nut, on the nut and be provided with fastener between the fastened connecting piece, fastener includes six fastening ring posts and fixed plate, be provided with the double-screw bolt between fastening ring post and the nut, the middle part of fixed plate is provided with the through-hole, the fixed plate is equidistant to be provided with the fastening groove post that six cooperation fastening ring posts used on one side towards the nut, the inside of fastening groove post is provided with the second bolt and between for threaded connection.

As a preferred embodiment of the present invention, one end of the top cap of the first bolt is hexagonal, the nut is located on the first bolt and has a hexagonal structure, and a thread groove for matching with the stud is provided in the side edge of the nut.

As a preferred embodiment of the present invention, the fastening ring post is a straight structure on the side where the stud is provided, and the fastening ring post and the fastening groove post are on the same horizontal line and leave a space therebetween.

As a preferred embodiment of the present invention, the fixing plate is of a circular structure and is located between the fastened connecting member and the nut, the distance between two symmetrical fastening groove posts is greater than the linear distance between the outer edges of the nut, and the second bolt passes through the fastening ring post and is connected with the fastening groove post.

Compared with the prior art, the beneficial effects of the utility model are as follows:

through fastener, can effectually avoid the nut to take place not hard up phenomenon when the operation, simultaneously, when the second bolt takes place not hard up, only can accomplish the fastening to the second bolt with small-size instrument, improved the security when the equipment operation to the problem of the work of influence equipment has been solved.
