Abstract

The present utility model provides a dustproof cover of electronic equipment. The cover comprises a silica gel plug and a fixing structure, the silica gel plug is fixed on an equipment basal body of the electronic equipment through the fixing structure; the silica gel plug comprises a silica gel main body and a fixing slice; the silica gel main body is composed of a silica gel ring, an elastic arm and a plug which are integrated; the fixing slice is fitted with the shape of the silica gel ring and covered and fixed on the surface of the silica gel ring. The fixing slice (a stainless steel sheet, a copper sheet, a composite material slice, etc.) which is not easily deformed is added on the prior silica gel ring and integrated with the silica gel main body to realize the supporting role, the silica gel ring sleeved on the equipment basal body is not easy to deform when the silica gel main body is pulled, and the situation that the silica gel ring cannot be automatically reset when the silica gel ring is deformed, or the silica gel ring is easy to shed from a screw when the silica gel ring is widened can be avoided.

Description

A kind of dust cap of electronic equipment

Technical field

The utility model relates to technical field of electronic equipment, relates in particular to a kind of dust cap of electronic equipment.

Background technology

At present, the dust cap scheme of electronic equipment is numerous, and some directly fills in dustproof with cork of a silica gel or other material, but inconvenient and dustproof stopper is easily lost when opening like this.

In order to prevent that stopper from losing, can increase some syndetons, stopper is connected on the equipment.The mode of this and equipment connection, useful soft rubber stopper (materials such as silica gel or TPU), useful screw, bolt or other structure are connected in the plug of band on the equipment.

But this when being connected in the soft rubber stopper of band on the equipment with screw, bolt etc., the annular strain that stopper is pushed down by screw when easily occurring pulling at stopper enlarges and deviates from, and is ineffective.

Summary of the invention

The purpose of this utility model is to provide a kind of dust cap of electronic equipment, prevents that falope ring from easily can't automatically reset because pullling distortion, avoided falope ring to deviate from from the equipment matrix.

The purpose of this utility model is achieved through the following technical solutions.

A kind of dust cap of electronic equipment comprises silica gel plug and fixed structure, and described silica gel plug is fixed on the equipment matrix of electronic equipment by fixed structure; Described silica gel plug comprises silica gel main body and fixing thin slice; Described silica gel main body is comprised of the falope ring that links into an integrated entity, elastic arm and stopper; The shape of described fixedly thin slice and falope ring is suitable, covers the surface of being fixed in falope ring.

Preferably, described fixedly thin slice and the moulding of silica gel main body integrated punching.

Preferably, described fixedly thin slice exceeds and is positioned at the elastic arm surface.

Preferably, described fixedly thin slice is specially stainless steel substrates, copper sheet or composite material sheet.

Compared with prior art, the utility model embodiment has following beneficial effect:

The utility model embodiment sets up an on-deformable fixedly thin slice (such as stainless steel substrates, copper sheet, composite material thin slice etc.) at existing falope ring, combine together with the silica gel main body, play a supporting role, guarantee that the falope ring that is enclosed within on the equipment matrix can not be out of shape when drawing the silica gel main body, prevented falope ring distortion and can't automatically reset or falope ring is widened and comes off from screw.

Fig. 3 is the decomposing schematic representation of silica gel plug among the utility model embodiment.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

See also the silica gel plug schematic diagram that assembles shown in Figure 1, and the part explosive view corresponding with Fig. 1 shown in Figure 2.In the present embodiment, dustproof cover structure comprises silica gel plug 2, nut and packing ring 3; Silica gel plug 2 is fixed on the equipment matrix 1 by nut and packing ring 3.

See also the exploded view of silica gel plug shown in Figure 32, silica gel plug 2 is comprised of silica gel main body 6 and stainless steel substrates 5 two parts in the present embodiment; The material of silica gel main body 6 is silica gel, and its structure is identical with existing silica gel plug structure, is comprised of the falope ring that links into an integrated entity, elastic arm and stopper.Stainless steel substrates 5 is located at the falope ring that pins for by screw 4, combines together with silica gel main body 6.Concrete grammar is: when doing silica gel plug, stainless steel substrates is put into accordingly the relevant position of mould, made silica gel main body 6 and stainless steel substrates 5 fully bonding, become a part.Stainless steel substrates 5 just can be played a supporting role like this, the falope ring that guarantee is enclosed within when drawing silica gel main body 6 on screw, bolt or the equipment matrix 1 can not be out of shape, and so just can prevent falope ring distortion and can't automatically reset or falope ring is widened and comes off from screw 4.

When design, stainless steel substrates 5 will exceed the elastic arm of silica gel main body 6, and with reference to A place among the figure 3, silica gel is peeled off along the stainless steel substrates edge when preventing from drawing silica gel plug 2, causes part to be broken.

In actual applications, stainless steel substrates 5 also available other non deformable material replaces, such as copper sheet, composite material sheet etc.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
