Description
Technical field
The utility model relates to a kind of nut, particularly a kind of Dustproof nut.
Background technique
General automobile wheel hub bolt and nut screw connection, the length of the thread part of bolt is longer than nut, is so just difficult to ensure card locking.But; the length of the thread part of bolt is longer than nut; the bolt thread just having part is chronically exposed under air; be easy to get rusty, corrosion screw bolt and nut, also has in car driving process; the cement often had on dust, earth or engineering truck can be attached to the bolt thread be exposed under air; make nut in the process of dismounting, damage bolt thread or nut thread, reduce the working life of bolt or nut.
Model utility content
For the deficiencies in the prior art part, the utility model provides a kind of Dustproof nut, and its structure is simple, has good dust-proof effect, and effectively avoid nut to wear and tear and get rusty, working life is more permanent.
The technological scheme provided for reaching above-mentioned object the utility model is: a kind of Dustproof nut, comprise nut body and removable insole pieces, described removable insole pieces is arranged on the outer wall of nut body, through before and after the inner chamber of described nut body, described nut body inner chamber is provided with internal thread, described nut body inner chamber end is provided with annular groove, described annular groove is provided with dust cover, thickness and the annular groove A/F of described dust cover are suitable, and described dust cover is installed on described nut body end seal in annular groove.
Further, the groove depth of described annular groove is 2-5mm, make dust cover can firmly be arranged on nut body end, be not easy to come off, effectively block dust, the bottom land of described annular groove is provided with rubber pad, described rubber pad and dust cover offset, and increase the frictional force between dust cover and rubber pad, dust cover are connected more fastening, avoid and nut body friction, increase the working life of nut body.
Further, described nut body external wall cross-section is regular hexagon, and the lumenal cross-section of described nut body is circular, facilitates nut to install and use.
Further, described nut body is formed in one, and described nut body is made up of stainless steel, avoids nut body to get rusty, and greatly increases the working life of nut body simultaneously.
Compared with prior art, there is following beneficial effect:
1. the utility model is provided with annular groove at described nut body inner chamber end, and described annular groove is provided with dust cover, and described dust cover, effectively by nut body end seal, can be good at blocking dust, and effectively avoid nut to wear and tear and get rusty, working life is more permanent; Meanwhile, the bottom land of described annular groove is provided with rubber pad, and described rubber pad and dust cover offset, and increases the frictional force between dust cover and rubber pad, dust cover is connected more fastening, avoids and nut body friction, increases the working life of nut body.
2. nut body described in the utility model is formed in one, and described nut body is made up of stainless steel, avoids nut body to get rusty, and greatly increases the working life of nut body simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model groove structure enlarged view.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
