The dustproof cloth is evenly provided with easy-tearing openings.

By adopting the scheme, the method has the following advantages:

because the utility model discloses a there is the pivot between two sides of the box of dustproof casing for desktop computer, the pivot is perpendicular with two lateral walls of box, and be the rotation form cooperation between two lateral walls of pivot and box, the pivot is located the position department that is close to the box panel, and the pivot is located the below of box panel fretwork section, there is the breach at the box top of pivot top, hold-down mechanism on the upper portion of box panel, there is dustproof cloth between pivot and breach, one end winding of dustproof cloth is in the pivot, another of dustproof yardage roll passes the breach and stretches into hold-down mechanism, stretch out from the both sides of box panel fretwork section respectively on the both sides of dustproof yardage roll. The dustproof cloth is used, so that dust entering from the hollowed-out end of the panel of the box body can be adsorbed, the dust is prevented from being adsorbed on the electrical element, and the service life of the electrical element is greatly prolonged.

Drawings

FIG. 1 is a structural use diagram of the dustproof case for desktop computers according to the present invention;

FIG. 2 is a left side view of FIG. 1;

fig. 3 is a schematic sectional view taken along line a-a of fig. 2.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-3, the utility model discloses a dustproof case for desktop computer includes rectangular box 1, all has fretwork section 101 on the panel of box 1 and the backplate. There is pivot 8 between two sides of box 1, and pivot 8 is perpendicular with two lateral walls of box 1, and is the cooperation of rotating form between two lateral walls of pivot 8 and box 1. The rotating shaft 8 is located at a position close to the panel of the box body 1, and the rotating shaft 8 is located below the hollow-out section 101 of the panel of the box body 1. The utility model discloses a dustproof cloth, including box 1 panel, pivot 8, the upper portion of box 1 panel has a breach, and there is dustproof cloth 3 on the upper portion of box 1 panel of pivot 8 top, have dustproof cloth 3 between pivot 8 and breach, and one end winding of dustproof cloth 3 is on pivot 8, and another of dustproof cloth 3 book passes the breach and stretches into hold-down mechanism, and the both sides that dustproof cloth 3 rolled up are stretched out from the both sides of box 1 panel fretwork section 101 respectively.
