Description

Damping screw for computer case

Technical Field

The present invention relates to a computer device, and more particularly, to a damping screw for a computer case.

Background

Computer cabinets typically employ modular steel cover plates that are secured with screws. After the existing screw is fastened, the computer is extremely difficult to take down again, and the computer is inconvenient to maintain and maintain. In addition, friction is likely to occur between the screw and the cover plate, which causes annoying noise.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve the technical problem that prior art exists to a computer machine case damping screw is provided.

The above technical problem of the present invention can be solved by the following technical solutions: the utility model provides a computer machine case damping screw, its characterized in that, computer machine case damping screw contain a screw main part, the screw main part contain a cylindric foundation column, the top of foundation column be equipped with one and hold between the fingers the head, the bottom of foundation column be equipped with a screw rod, the inside of foundation column be equipped with a damping circular slot array of constituteing by the damping circular slot, the damping circular slot evenly distribute in the circumference of foundation column on, the damping circular slot in be equipped with a separable damping stick respectively, the damping stick contain a bar-shaped main rod body, the head of main rod body be equipped with a discoid damping coiled hair.

As a better embodiment of the utility model, the damping rod is made of nylon.

The utility model discloses a computer machine case damping screw has following advantage: during the use, the user can directly screw in the preformed hole of reserving on the quick-witted case apron with the screw main part to screw the screw main part, the damping coiled hair of damping rod 3 begins closely to extrude the edge of preformed hole this moment, makes the screw main part fixed the quick-witted case apron completely. At this moment, because the effect of damping coiled hair, the apron can firmly be fixed to the screw main part, and simultaneously, when the user need dismantle the apron, the user can easily lift the screw main part off again, kills two birds with one stone. The damping screw of the computer case is simple in structure, obvious in effect, low in cost and high in practicability.

Drawings

wherein,

1. computer chassis damping screw; 2. a screw body; 21. a base pillar; 22. kneading the head; 23. a screw; 24. a damping circular groove; 3. a damping rod; 31. a main rod body; 32. the pan head is damped.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

As shown in fig. 1 to 5, the damping screw 1 of the computer case comprises a screw main body 2, the screw main body 2 comprises a cylindrical base pillar 21, a top of the base pillar 21 is provided with a knob 22, a bottom of the base pillar 21 is provided with a screw 23, an array of damping circular grooves 24 is provided inside the base pillar 21, the damping circular grooves 24 are uniformly distributed on the circumference of the base pillar 21, the damping circular grooves 24 are respectively provided with a separable damping rod 3, the damping rod 3 comprises a rod-shaped main rod body 31, and a head of the main rod body 31 is provided with a disc-shaped damping disk head 32.

The damping rod 3 is made of nylon.

When the screw main body 2 is used, as shown in fig. 1 and fig. 2, a user can directly screw the screw main body 2 into a prepared hole reserved on a chassis cover plate and screw the screw main body 2, and at the moment, the damping pan head 32 of the damping rod 3 starts to tightly press the edge of the prepared hole, so that the screw main body 2 completely fixes the chassis cover plate. At this moment, because the effect of damping coiled hair 32, the screw main part 2 can firmly fix the apron, simultaneously, when the user need dismantle the apron, the user can easily lift screw main part 2 off again, kills two birds with one stone.

In addition, because the damping rod 3 is made of nylon, the damping rod has certain elasticity, the friction between a screw and a cover plate is avoided, and the comfort of using the computer is improved.

The damping screw of the computer case is simple in structure, obvious in effect, low in cost and high in practicability.

Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
