Description

Novel dustproof and waterproof structure

Technical Field

The utility model belongs to the technical field of satellite antenna accessories, and particularly relates to a novel dustproof and waterproof structure.

Background

The tuner and the frequency reducer are one of important accessories of the satellite antenna, each accessory comprises a shell and a cover body, the cover body is covered at the lower end of the shell (the lower end of the installation direction), the inner diameter of the cover body is equal to the outer diameter of the shell, the design form is easy to cause rainwater to enter from a gap, the waterproof effect is poor, a sealing gasket is sometimes added for sealing treatment, but the sealing gasket is easy to age and deform, and the waterproof performance of the sealing gasket cannot be guaranteed.

Disclosure of utility model

The utility model provides a novel dustproof and waterproof structure which can solve the problems pointed out in the background art.

The utility model provides a novel dustproof and waterproof structure, includes casing body and cap, the cap inside lining is in the one end of casing body.

Preferably, the corresponding position of the shell body is provided with a limiting clamping groove, and the inner side end of the cap is in limiting fit with the limiting clamping groove.

Preferably, the edge of one end of the inner side of the cap is provided with a bulge, and the corresponding position of the shell body is provided with a limit groove matched with the bulge.

Preferably, the protrusions are arc-shaped protrusions.

The beneficial effects are that: the novel dustproof and waterproof structure provided by the utility model has the advantages that firstly, the cap adopts the lining type connection design, rainwater can be prevented from flowing into the shell body from the gap, in addition, the matching design of the bulge and the limiting groove is equivalent to the design of a secondary sealing structure, the sealing effect is improved, and the waterproof performance of the product can be ensured even if the lower end of the product is immersed in water.

Detailed Description

One embodiment of the present utility model will be described in detail below with reference to the attached drawings, but it should be understood that the scope of the present utility model is not limited by the embodiment.

Examples:

As shown in fig. 1-4, the novel dustproof and waterproof structure provided by the embodiment of the utility model comprises a shell body 1 and a cap 2, wherein the cap 2 is lined in one end of the shell body 1.

In some embodiments, the corresponding position of the housing body 1 is provided with a limit clamping groove 3, the inner side end of the cap 2 is in limit fit with the limit clamping groove 3, the structure can realize quick connection, and also can adopt threaded connection, the connecting end of the cap 2 is provided with external threads, the corresponding position of the housing body 1 is provided with internal threads, the quick connection cannot be realized through threaded connection, and the operation is not good, so that the design form of the limit clamping groove 3 is preferably selected.

In some embodiments, the edge of the inner side end of the cap 2 is provided with a protrusion 4, the corresponding position of the housing body 1 is provided with a limit groove 5 matched with the protrusion 4, the protrusion 4 is an arc protrusion, the arc protrusion is conveniently clamped in, the protrusion 4 and the limit groove 5 are matched to be equivalent to a sealing structure, the sealing performance can be improved, and the cap 2 can be prevented from being easily detached.

The following disclosure is only a few specific embodiments of the utility model, but the embodiments of the utility model are not limited thereto, and any changes that may be contemplated by those skilled in the art should fall within the scope of the utility model.
