the utility model provides a bolt lag, the bolt lag sets up in the bolt tip one section that stretches out the nut, the bolt lag includes the cover body, the cover body is the pipe form, and the cover body is made by plastic materials, and the length value of the cover body is greater than the length value of the one section that the bolt stretches out the nut, and the cover body inner wall is provided with the screw thread corresponding with the bolt, and the cover body screw thread cover is put in the one section that the bolt stretches out the nut, and cover body one end supports to the nut, and the one end intussuseption that the nut was kept away from to the cover body is filled with grease.

In order to further realize the utility model, the following technical scheme can be preferably selected:

preferably, the sleeve body is made of elastic materials, a gap is formed in the side wall of the sleeve body, and two ends of the gap are respectively communicated to two ends of the sleeve body.

Preferably, the middle part of the cross section of the gap is semicircular.

Preferably, the gap is filled with grease.

Preferably, the cover body is provided with the apron away from the one end of nut, the apron seals the terminal surface of laminating in the cover body one end of keeping away from the nut, and the diameter value of apron is not less than the external diameter value of the cover body, and the apron middle part is provided with the lock post, the lock post screw thread cover is in the cover body one section of keeping away from the nut.

Through the technical scheme, the utility model has the beneficial effects that:

after the fastening of the bolt is completed, the sleeve body is sleeved on the bolt by threads until the sleeve body is screwed to the position of the nut, the end part of the sleeve body is filled with a proper amount of grease, and then the sealing cover is screwed. When the bolts are disassembled and assembled again, the sleeve body can be screwed out from the bolts, and the sleeve body can be pulled out from the bolts through the gaps.

The utility model has the advantages of low cost, easy operation and wide application range.

Detailed Description

In the description of the present utility model, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

As shown in fig. 1-5, a bolt protecting sleeve is arranged on a section of a bolt end extending out of a nut, the bolt protecting sleeve comprises a sleeve body 1, the sleeve body 1 is in a circular tube shape, the sleeve body 1 is made of plastic materials, the length value of the sleeve body 1 is larger than that of the section of the bolt extending out of the nut, threads corresponding to the bolt are arranged on the inner wall of the sleeve body 1, the sleeve body 1 is in threaded sleeve fit with the section of the bolt extending out of the nut, one end of the sleeve body 1 abuts against the nut, and grease is filled in one end of the sleeve body 1 far away from the nut.

In order to facilitate the disassembly of the sleeve body 1 and the repeated use again, the sleeve body 1 is made of elastic materials, the side wall of the sleeve body 1 is provided with a gap 2, and two ends of the gap 2 are respectively communicated with two ends of the sleeve body 1.

In order to ensure the connection reliability of the sleeve body 1, the middle part of the cross section of the gap 2 is semicircular.

In order to ensure the protective effect, the gap 2 is filled with grease.

In order to further guarantee the protection effect, one end that nut was kept away from to the cover body 1 is provided with apron 3, and apron 3 seal laminating is in the terminal surface that the nut was kept away from to the cover body 1, and the diameter value of apron 3 is not less than the external diameter value of the cover body 1, and apron 3 middle part is provided with lock post 4, and lock post 4 screw thread cover is in the one section that the nut was kept away from to the cover body 1.
