Through the technical scheme, after the nut 71 and the bolt 70 are fixed, the fastener protection device can bypass the barrier between the nut 71 and the bolt 70, and meanwhile, the nut 71 and the bolt 70 exposed outside are placed in the fastener protection device to isolate the fastener from the external environment. Therefore, the fastener can be protected, and the problems of rusting, corrosion and the like of the fastener can be effectively prevented.

Note that the "bolt 70" described above includes both the bolt head 73 and the bolt shank 72 (see fig. 4).

Further, the protection body can be made of rubber materials.

In the above, the fastening structure 30 may be provided independently or attached to the protection body.

In a first embodiment, as shown in fig. 2, the fastening structure 30 is provided independently of the protective body. Specifically, the fastening structure 30 includes an elastic rubber ring provided independently of the shield body. Optionally, the rubber ring is provided as a rubber ring. When in use, as shown in fig. 3, the rubber ring can be sleeved on the root of the upper protective cover 10 and/or the lower protective cover 20 to fix the upper protective cover 10 and/or the lower protective cover 20 on the fastener, so as to prevent the upper protective cover 10 and the lower protective cover 20 from being separated from the fastener and losing the protection function.

It should be noted that the "root" refers to a position near the opening of the fastener after the upper protective cover 10 and the lower protective cover 20 are covered on the fastener; or, it means a position near the obstacle 74 after the upper and lower protection covers 10 and 20 are covered on the fastener.

In a second embodiment, as shown in fig. 1, the fastening structure 30 is attached to the protection body. Specifically, the fastening structure 30 includes an elastic band attached to the shield body, and both ends of the elastic band are connected to the wall portions of the upper shield 10 or the lower shield 20. Preferably, both ends of the elastic band are simultaneously connected to the wall portion of the lower protection cover 20; the elastic belt is a rubber belt. The elastic band can be wound around one of the protective covers, starting from the other protective cover, and firmly covers the fastening means. In the present embodiment, after the upper and lower protection covers 10 and 20 are covered on the fastening member, the elastic band is wound around the upper protection cover 10 around the obstacle 74 with the lower protection cover 20 as a starting point, so that the upper and lower protection covers 10 and 20 can be firmly covered on the fastening member.

In order to prevent the elastic band wound around the upper protection cover 10 from being separated from the upper protection cover 10, a groove may be provided on a circumferential side wall of the upper protection cover 10. When in use, the elastic band is clamped into the groove, so that the elastic band can be prevented from being separated from the upper protective cover 10.

Compared with the first embodiment, the second embodiment has the advantages that: the fastening structure 30 is integrated with the fastening body, improving the portability of the fastener guard.

The third concrete implementation mode: the first embodiment and the second embodiment are combined, that is, the fastening structure 30 includes both the rubber ring in the first embodiment and the elastic band in the second embodiment.

In practice, generally speaking, as shown in fig. 4, the height of the screw portion 72 protruding from the plane is greater than the height of the bolt head 73 protruding from the plane. Therefore, it is preferable that the lengths of the upper and lower protection covers 10 and 20 should be different. In an alternative embodiment, the upper protective cover 10 has a length greater than that of the lower protective cover 20, and the elastic band is disposed on the lower protective cover 20. The opening edge of the upper protection cover 10 and the opening edge of the lower protection cover 20 are partially bonded together, and a gap 40 is provided between the remaining portions. It is also understood that an opening, namely the gap 40, is formed in the integrally formed upper protective covering 10 and lower protective covering 20. The shape of the gap 40 may be varied. It should be noted, however, that the gap 40 is arranged to run substantially in the circumferential direction of the guard body, rather than in the axial direction.

It should be explained that the length of the upper protective cover 10 and the length of the lower protective cover 20 are measured in such a way that: the length of the upper shield 10 refers to the distance from the top of the upper shield 10 to the junction of the upper shield 10 and the lower shield 20; the length of the lower protective cap 20 is a distance for setting the bottom of the lower protective cap 20 to the junction of the upper protective cap 10 and the lower protective cap 20.

In an alternative embodiment, the overall shape of the gap 40 is configured to be arc-shaped, so that a closing blade 50 can be formed at the opening of the upper protective cover 10 or the lower protective cover 20. Preferably, the closing blade 50 is formed at an opening of the lower protection cover 20. The purpose of the closure leaf 50 is that the closure leaf 50 helps the lower protective cover 20 to abut against the fastener when the lower protective cover 20 is placed over the fastener.

The wall part is provided with an oil filling hole 60, so that in subsequent maintenance, an anti-corrosion medium, such as butter or liquid oil and the like, can be added into the protection body at any time through the oil filling hole 60 on the fastener protection device, and oil lubrication and rust prevention treatment can be carried out on the nut and the bolt at any time. Alternatively, an oil hole 60 is provided at both the top of the upper protection cover 10 and the bottom of the lower protection cover 20. Further, a sealing cover, which may be a rubber stopper, is provided at the oil filling hole 60.

In order to facilitate understanding of the technical scheme of the invention, the working principle of the invention is briefly described as follows: in use, as shown in fig. 3 or 4, the upper protective cover 10 is covered on the nut 71 and the screw portion 72, and the protective body is made of an elastic rubber material, so that after the lower protective cover 20 is stretched, the lower protective cover 20 can be covered on the bolt head 73, and then the upper protective cover 10 and the lower protective cover 20 are fixed by the fastening structure 30 to be prevented from being separated from the nut 71 and the bolt 70. In the first embodiment, as shown in fig. 2 to 4, the fastening structure 30 is provided independently from the protective body. Therefore, the fastening is achieved by sleeving the rubber ring on the root of the upper protective cover 10 and/or the lower protective cover 20. Since the rubber ring has an inward contracting force, the upper and/or

lower boots

10 and 20 can be tightly bound to the nut 71 and the bolt. In the second embodiment, referring to fig. 1, since the fastening structure 30 is attached to the shield body and the rubber band is disposed on the wall of the lower protective cover 20, it is necessary to stretch the rubber band from the lower protective cover 20 to the upper protective cover 10 and wind the rubber band around the upper protective cover 10 when fixing. Preferably around the root of the upper protective cover 10. Although the drawings do not show the second embodiment of the fastening structure 30 after fastening, the second embodiment will be understood by those skilled in the art from the above description and the first embodiment and the teaching of fig. 3.

In addition to the fastening structure 30 having a fastening function for the fastening member, the upper protection cover 10 and the lower protection cover 20 have a fastening function in their own properties. Specifically, since the upper and

lower boots

10 and 20 are made of a rubber material having elasticity, they have an inward tightening force by themselves. In addition, a certain friction force is generated between the upper and lower protection covers 10 and 20, and the nut 71 and the bolt 70 after the installation. These factors all contribute to the upper and

lower boots

10 and 20 securely covering the fasteners.

It should be noted that the fastener guard of the present invention is primarily directed to the bolt 70 and nut 71 as shown in fig. 4, and that there is an obstruction between the bolt 70 and nut 71. Of course, this fastener guard may also be suitable if it can accommodate other fasteners.

The preferred embodiments of the present invention have been described in detail, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. The invention is not described in detail in order to avoid unnecessary repetition.

In addition, any combination of the various embodiments of the present invention is also possible, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
