Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The first embodiment:

the dustproof computer case shown in fig. 1-4 comprises a case 1, wherein a caulking groove 11 is arranged on one side of the case 1, a plurality of heat dissipation holes 12 are arranged on the inner side of the caulking groove 11, a movable frame 2 is arranged on the inner side of the caulking groove 11, the movable frame 2 comprises an outer frame body 3 and an inner frame body 4, one end of the outer frame body 3 is hinged with the caulking groove 11, the other end of the outer frame body 3 is clamped with the caulking groove 11, the inner frame body 4 is arranged in a frame of the outer frame body 3, the inner frame body 4 is in clearance fit with the outer frame body 3, the inner frame body 4 corresponds to the heat dissipation holes 12, a through groove 31 is arranged at the free end of the outer frame body 3, one end of the inner frame body 4 is inserted into the through groove 31, one end of the outer side of the inner wall of the inner frame body 4 is provided with a plurality of dust baffles 41, the dust baffles 41 are connected with the inner frame, two ends of the connecting rod 42 are hinged with the dust baffle 41, and one end of the inner side of the inner frame wall of the inner frame body 4 is fixedly provided with a dust filter 43.

Preferably, a fastening pad 13 is arranged at the joint of the free end of the caulking groove 11 and the outer frame body 3, and a rubber fastening pad is adopted, so that the limit fastening performance of the joint of the free end of the outer frame body 3 is ensured when the outer frame body is closed and is in the caulking groove 11.

Preferably, the front side wall of the free end of the outer frame 3 is provided with a finger hole 32, and the finger hole 32 can be conveniently held by a user to extend into the outer frame, so as to turn the outer frame 3 outwards and open.

Preferably, the dust baffle 41 is disposed in the frame of the inner frame 4 from top to bottom in a louver-shaped inclined manner, so that the dust baffle 41 can filter and block external dust to a great extent after being turned over and adjusted to be opened.

Second embodiment:

furthermore, the outer frame 3 is in clearance fit with the caulking groove 11, so that the sealing connectivity at the caulking groove 11 is improved, and further, the dust is prevented from entering.

Further, the non-slip mat 33 is disposed in the finger hole 32, and the non-slip mat is made of rubber, so that the user can conveniently operate the outer frame 3 when opening the outer frame.
