Description

New dustproof nut

technical field

The utility model relates to a nut, in particular to a novel dustproof nut.

Background technique

Generally, the hub bolts of automobiles are matched with nuts, and the length of the thread portion of the bolts is longer than that of the nuts, so that it is difficult to ensure locking. However, the length of the thread part of the bolt is longer than that of the nut, and some of the thread of the bolt will be exposed to the air for a long time, which is easy to rust, corrode the bolt and nut, and there is often dust in the process of driving the car , soil or cement on the engineering vehicle will adhere to the bolt threads exposed to the air, so that the nuts will damage the bolt threads or nut threads during the disassembly process, reducing the service life of the bolts or nuts.

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides a novel dust-proof nut, which has a simple structure and good dust-proof effect, effectively avoids wear and rust of the nut, and has a longer service life.

In order to achieve the above purpose, the technical solution provided by the utility model is: a new type of dustproof nut, including a nut body and a movable gasket, the movable gasket is installed on the outer wall of the nut body, and the inner cavity of the nut body runs through , the inner cavity of the nut body is provided with internal threads, and the end of the inner cavity of the nut body is provided with a ring groove, and the ring groove is equipped with a dust cover, and the thickness of the dust cover is adapted to the opening width of the ring groove, The dust cover is clamped in the ring groove to seal the end of the nut body.

Further, the groove depth of the ring groove is 2-5mm, so that the dust cover can be firmly installed on the end of the nut body, not easy to fall off, and effectively block the dust. The bottom of the ring groove is equipped with a rubber pad, so The rubber pad is offset against the dust cover to increase the friction between the dust cover and the rubber pad, so that the dust cover is connected more tightly, avoiding friction with the nut body, and increasing the service life of the nut body.

Further, the cross section of the outer wall of the nut body is a regular hexagon, and the cross section of the inner cavity of the nut body is circular, which is convenient for nut installation and use.

Further, the nut body is integrally formed, and the nut body is made of stainless steel, which prevents the nut body from rusting and greatly increases the service life of the nut body.

Compared with the prior art, it has the following beneficial effects:

1. The utility model is provided with a ring groove at the end of the inner cavity of the nut body, and the ring groove is equipped with a dust cover, and the dust cover effectively seals the end of the nut body, which can well block dust and effectively avoid The nut is worn and rusted, and the service life is longer; at the same time, a rubber pad is installed on the bottom of the ring groove, and the rubber pad is offset against the dust cover to increase the friction between the dust cover and the rubber pad, so that the dustproof The cover is connected more tightly to avoid friction with the nut body and increase the service life of the nut body.

2. The nut body of the utility model is integrally formed, and the nut body is made of stainless steel, which prevents the nut body from rusting and greatly increases the service life of the nut body.

Description of drawings

Fig. 1 is a structural representation of the utility model;

Fig. 2 is an enlarged view of the ring groove structure of the utility model.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Detailed ways

As shown in Figures 1 to 2, a new type of dustproof nut includes a nut body 1 and a movable gasket 2, the movable gasket 2 is installed on the outer wall of the nut body 1, and the inner cavity of the nut body 1 runs through front and back , the inner cavity of the nut body 1 is provided with an internal thread 3, which is convenient for the nut body 1 and the bolt (not shown) to be installed in rotation.

The end of the inner cavity of the nut body 1 is provided with an annular groove 6, and the annular groove 6 is equipped with a dustproof cover 4. The thickness of the dustproof cover 4 is adapted to the opening width of the annular groove 6. The dustproof cover 4 Fitted in the ring groove 6 to seal the end of the nut body 1, the groove depth of the ring groove 6 is 2-5mm, so that the dust cover 4 can be firmly installed on the end of the nut body 1, and it is not easy to fall off, effectively To block dust, a rubber pad 5 is installed at the bottom of the ring groove 6, and the rubber pad 5 is offset against the dust cover 4 to increase the friction between the dust cover 4 and the rubber pad 5, so that the dust cover 4 is connected Tighter, avoiding friction with the nut body 1, increasing the service life of the nut body 1.

The cross-section of the outer wall of the nut body 1 is a regular hexagon, and the cross-section of the inner cavity of the nut body 1 is circular, which is convenient for nut installation and use. The nut body 1 is integrally formed, and the nut body 1 is made of stainless steel , to prevent the nut body 1 from rusting, and at the same time greatly increase the service life of the nut body 1 .

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modification or equivalent replacement of the technical solutions without departing from the spirit and scope of the technical solutions of the present utility model, all of which shall be covered by the scope of the claims of the present utility model.
