Embodiment Construction

[0012] see figure 1 and figure 2 A preferred embodiment of the ventilation hole shielding device 8 of the present invention includes a fixed seat 10 , a sliding seat 30 , a shielding module 50 , an operating portion 70 and a cover 90 .

[0013] The fixing seat 10 is generally a horizontally long rectangle. A rectangular ventilation area 11 is arranged in the middle of the fixing base 10, and a plurality of longitudinal ventilation holes are arranged in the ventilation area 11 at intervals in the transverse direction. A slot 12 is defined in the middle of the fixing base 10 near its right end, and a locking member 13 is installed in the slot 12 . The fixing base 10 is respectively provided with a first rack 14 on the front and rear sides of the slot 12 . Two lead screw fixing bodies 15 are respectively arranged at intervals on the front and rear side edges of the fixing base 10 for erecting the lead screw 17 . Each screw fixing body 15 includes a supporting block 151 and a...

Abstract

The invention discloses a shielding device of a ventilation hole, comprising a fixed seat, a sliding seat arranged on the fixed seat in a sliding manner, an operation part rotatably arranged on the sliding seat and a shielding module arranged on the sliding seat, wherein the fixed seat is provided with a first rack and a first hook hanging piece; the sliding seat is provided with a gear set and a third hook hanging piece; the third hook hanging piece is away from the first rack compared with the first hook hanging piece; the gear set comprises a first gear and a second gear which are coaxially arranged; the first gear is meshed with the first rack; a second arc rack is arranged at the operation part and is meshed with the second gear; the shielding module comprises a plurality of shielding pieces and a connected shaft body capable of driving the shielding pieces to rotate simultaneously; the connected shaft body is provided with two second hook hanging pieces which are positioned between the first hook hanging piece and the third hook hanging piece; a first spring is connected between the first hook hanging piece and the adjacent second hook hanging piece; and a second spring is connected between the third hook hanging piece and the adjacent second hook hanging piece. By operating the operation part, the opening-closing state of the shielding pieces can be controlled, thereby effectively preventing dust.

Description

technical field [0001] The invention relates to a ventilation hole shielding device. Background technique [0002] Computer cases are generally provided with dense ventilation holes on the front panel. When the computer is in operation, the ventilation holes serve the purpose of helping the computer case to dissipate heat. However, the air vents also allow dust outside the computer case to enter the inside of the computer case, especially a large amount of dust enters the computer case through the air vents when the computer stops working without cooling. This endangers the electronic components inside the computer case and affects the life of the computer. Contents of the invention [0003] In view of the above, it is necessary to provide a ventilation hole shielding device that can be adjusted in good time and effectively prevent dust. [0004] A ventilation hole shielding device comprises a fixed seat, a sliding seat slidably mounted on the fixed seat, an operating p...
