Abstract

The utility model provides a dustproof mechanical keyboard, the structure includes mechanical switch to and the key cap that is connected with mechanical switch, mechanical switch form by upper cover and base lock, be provided with in mechanical switch's inside and press handle and contact piece, run through the middle part of upper cover and peg graft fixedly with the pillar of key cap according to the axle core of handle, be equipped with the spring and fix on the base at the periphery cover according to participating in of handle, the upper cover be provided with the dust cover of reticulation check at top surface, the centre bore flute profile form of this dust cover is the same with the pillar shape of key cap, dust cover and upper cover formula fixed connection structure as an organic whole or split type laminating connection structure, the utility model discloses with strong points, the existence of dust cover has guaranteed that the clearance between key cap and the upper cover is in the best driving fit degree, has stoped the dust granule to get into internal breakdown electrical property function, plays simultaneously and reduces key cap swing effect, improves and presses down time scalar sum mechanical durability, and the practicality is strong, and market prospect is huge.

Description

A kind of dust-proof machine keyboard

Technical field:

The utility model relates to computer fittings technical field, specifically refers to a kind of mechanical keyboard with dust-proof effect.

Background technology:

Keyboard is the modal input equipment of computer, and operator is by knocking keyboard to the various instruction and data of computer input, the work of command computer.

But existing keyboard does not have dustproof construction, when knocking the button on keyboard as operator, button pumps, dust granule in air can enter the inside of mechanical switch by the gap between keycap and upper cover, increase the frictional force between each part, cause the insensitive even stuck situation of mechanical switch appearance activity, or the situation of the large not even conducting of contact resistance; Button very easily weares and teares in reciprocatory movement, and dust granules adds up too much directly to block button, causes button malfunction, directly reduces the useful life of button.

Utility model content:

For problem existing in above-mentioned background technology, the dust-proof machine keyboard that the utility model provides a kind of modern design, structure simple, practical.

For this reason, the technical solution adopted in the utility model is: a kind of dust-proof machine keyboard, and structure comprises mechanical switch, and the keycap be connected with mechanical switch.Described mechanical switch is fastened by upper cover and pedestal and forms, the inside of mechanical switch is provided with handle and contact chip, the axle core at handle top runs through the middle part of upper cover and fixes with the pillar grafting of keycap, pin bottom handle is arranged with spring in periphery and is fixed on pedestal, described contact chip is made up of the static contact and movable contact spring being in spring side, described upper cover is provided with the dust cover of reticulate pattern lattice at top surface, and the centre bore groove shape of this dust cover is identical with the strut configurations of keycap.

The measure taked further is: described dust cover and upper cover are integral type fixed connection structure or are split typely fitted and connected structure.Flexible design is changeable, to meet design needs and the structural adjustment of different product structure.

The advantage that the utility model is had by such design is: with strong points, and structure is simple, little to existing mechanical keyboard change, the centre bore groove shape of dust cover is identical with the strut configurations of keycap, ensure that the gap between keycap and upper cover is in best closed intensity, play the effect reducing keycap swing and product stability simultaneously, feel is not affected in use procedure, conscientiously prevent dust granule to enter mechanical switch internal and damage electrical functionality, reduce friction, improve compression number and the mechanical endurance of mechanical switch.

Accompanying drawing illustrates:

Fig. 1 is overall structure schematic diagram of the present utility model;

Fig. 2 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model;

Fig. 3 is the split-type structural figure of dust cover and upper cover.

In figure, 1, mechanical switch, 11, upper cover, 12, pedestal, 13, handle, 131, axle core, 132, pin, 14, spring, 15, static contact, 16, movable contact spring, 2, keycap, 21, pillar, 3, dust cover.

Embodiment:

Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.

As shown in Figure 1 to Figure 2, structure of the present utility model comprises mechanical switch 1, and the keycap 2 be connected with mechanical switch 1.Described mechanical switch 1 is fastened by upper cover 11 and pedestal 12 and forms, the inside of mechanical switch 1 is provided with handle 13 and contact chip, the axle core 131 at handle 13 top runs through the middle part of upper cover 11 and fixes with pillar 21 grafting of keycap 2, pin 132 bottom handle 13 is arranged with spring 14 in periphery and is fixed on pedestal 12, described contact chip is made up of the static contact 15 and movable contact spring 16 being in spring 14 side, described upper cover 11 is provided with the dust cover 3 of reticulate pattern lattice at top surface, and the centre bore groove shape of this dust cover 3 is identical with pillar 21 shape of keycap 2.

With reference to shown in Fig. 1, Fig. 2, dust cover 3 and upper cover 11 are designed to the structure that integral type is fixedly connected with.

As shown in Figure 3, dust cover 3 of the present utility model can also be designed to the split type structure be fitted and connected with upper cover 11.

These are only and describe general principle of the present utility model, principal character and advantage.Not for limiting the utility model, under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all should fall within protection range of the present utility model.
