Description

Technical Field

[0001] This utility model relates to the field of computer technology, specifically to a computer dustproof device. Background Technology

[0002] A computer, commonly known as a PC, is a modern electronic computing machine used for high-speed calculations. It can perform numerical calculations, logical calculations, and has storage and memory functions. It is a modern intelligent electronic device that can run according to a program and automatically and quickly process massive amounts of data.

[0003] Currently, computers are widely used. Desktop computers are economical and suitable for home and office use. The computer case is a basic component of computer hardware. During the design process, it is necessary to ensure good ventilation and heat dissipation performance. To improve heat dissipation performance, the area of ​​the heat dissipation holes usually needs to be increased. When the area of ​​the heat dissipation holes is large, external dust can easily enter the case, causing dust accumulation on the electronic components on the computer motherboard and making them prone to failure. The traditional method is to add a filter screen to the heat dissipation holes to isolate dust. However, over a long period of use, dust will gradually accumulate on the filter screen, which will affect the normal heat dissipation of the device. If you wipe it with a towel or wet paper, dust can easily fall into the case. Removing the filter screen for cleaning usually requires tools and is quite cumbersome. Therefore, we propose a computer dust prevention device. Utility Model Content

[0004] The purpose of this utility model is to provide a computer dustproof device that is easy to clean. It solves the problem that dust will gradually accumulate on the filter screen during long-term use, which will affect the normal heat dissipation of the device. If you use a towel or wet paper to wipe it on the outside, the dust will easily fall into the inside of the computer case. And removing the filter screen for cleaning usually requires tools, which is quite cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a computer dustproof device, including a chassis, on both the left and right sides of the chassis, heat dissipation slots are provided, and on both the left and right sides of the chassis, a fixing frame corresponding to the heat dissipation slots is provided, a dustproof filter is provided inside the fixing frame, and positioning slots are provided on both the front and rear sides inside the fixing frame, with a plurality of equidistantly distributed snap-fit ​​grooves at one end of the positioning slots, and elastic plates adapted to the positioning slots are fixedly connected to both the front and rear ends of both the left and right sides of the chassis, with a plurality of equidistantly distributed snap-fit ​​protrusions at one end of the elastic plates, and movable slots are provided on both the front and rear ends of the fixing frame, with movable pushers provided inside the movable slots.

[0006] Preferably, anti-slip support blocks are fixedly installed at both the left and right ends of the bottom of the chassis, and anti-slip rubber blocks are provided at the bottom of the anti-slip support blocks.

[0007] Preferably, the number of the snap-fit ​​protrusions and snap-fit ​​grooves are the same, and the snap-fit ​​protrusions snap into the inner side of the snap-fit ​​grooves.

[0009] Preferably, sealing slots are provided on both the left and right sides of the chassis, and a sealing strip is fixedly connected to the side of the fixing frame corresponding to the chassis.

[0010] Preferably, the longitudinal section of the sealing groove is rectangular.

[0011] Preferably, the sealing strip is made of elastic rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the setting of a fixed frame, heat dissipation groove and dust filter, can achieve heat dissipation when the chassis is working normally. When it is necessary to clean the dust filter, simply push the movable pusher in the movable groove at both ends of the fixed frame. The movement of the movable pusher can cause the elastic plate to deform slightly in the positioning groove. The deformed elastic plate will drive the locking protrusion to disengage from the locking groove. Then, the fixed frame can be removed from both sides of the chassis, making it convenient for the user to move to another place to thoroughly clean the dust filter, which is beneficial to the user.

[0014] 2. By setting up a sealing groove and a sealing strip, this utility model can improve the sealing performance between the fixed frame and the chassis by having the sealing strip enter the sealing groove when the fixed frame is installed close to the chassis, thus avoiding the existence of gaps between the fixed frame and the chassis.

A dustproof filter 3 is provided inside the fixed frame 2, and positioning slots 7 are provided on both the front and rear sides inside the fixed frame 2. Multiple equally spaced snap-fit ​​grooves 13 are provided at one end of the positioning slot 7. Elastic plates 8 adapted to the positioning slots 7 are fixedly connected to both the front and rear ends of both the left and right sides of the chassis 1. Multiple equally spaced snap-fit ​​protrusions 9 are provided at one end of the elastic plate 8. The number of snap-fit ​​protrusions 9 and snap-fit ​​grooves 13 is the same, and the snap-fit ​​protrusions 9 snap into the inner side of the snap-fit ​​grooves 13. Movable slots 5 are provided on both the front and rear ends of the fixed frame 2. Movable pushers 6 are provided inside the movable slots 5. Limiting sliders are provided on both the left and right sides of the movable pushers 6, and one side of the movable pushers 6 is in contact with the elastic plate 8.

[0026] This technical solution, through the setting of the fixed frame 2, the heat dissipation channel 11, and the dust filter 3, can achieve heat dissipation when the chassis 1 is working normally. When it is necessary to clean the dust filter 3, simply push the movable pusher 6 in the movable slots 5 at both ends of the fixed frame 2. The movement of the movable pusher 6 can cause the elastic plate 8 to deform slightly in the positioning slot 7. The deformed elastic plate 8 will drive the locking protrusion 9 to disengage from the locking groove 13. Then, the fixed frame 2 can be removed from both sides of the chassis 1, making it convenient for the user to move to another place to thoroughly clean the dust filter 3. After the dust filter 3 is cleaned, after the elastic plate 8 is aligned with the positioning slot 7, push the fixed frame 2 close to the chassis 1. Then, after the elastic plate 8 undergoes slight deformation, it will drive the locking protrusion 9 to re-engage in the locking groove 13, realizing the quick positioning of the fixed frame 2 and the dust filter 3, which is convenient for the user.

[0027] Example 2

[0030] Example 3

[0031] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the chassis 1 has sealing slots 10 on both the left and right sides. The fixed frame 2 is fixedly connected to the side corresponding to the chassis 1 with a sealing strip 12. The longitudinal section of the sealing slot 10 is rectangular, and the sealing strip 12 is made of elastic rubber.

[0032] This technical solution: By setting the sealing groove 10 and the sealing strip 12, when the fixed frame 2 is installed close to the chassis 1, the sealing strip 12 will enter the sealing groove 10, thereby improving the sealing between the fixed frame 2 and the chassis 1 and avoiding the existence of gaps between the fixed frame 2 and the chassis 1.
