Description

Technical Field

[0001] The utility model relates to the technical field of computer dust prevention, in particular to a computer air inlet dust prevention device. Background Art

[0002] Computers are very sensitive to dust. Dust can enter the interior of computer equipment and clog the heat dissipation holes, causing the temperature of the equipment to rise or even cause equipment failure. In addition, dust can also affect the normal operation of the equipment and reduce its performance. Therefore, in order to ensure the normal operation of computer equipment and extend the service life of the equipment, computer dust prevention is essential.

[0003] A Chinese patent discloses a dustproof mechanism for an electronic computer (Announcement No. CN215965437U). The patented technology uses a driving structure to drive a baffle through a connecting frame to close or open the opening of the ventilation hole on the mounting plate. When the computer is not in use, the baffle effectively blocks dust from entering the chassis, thereby blocking dust and effectively reducing the dust in the air from entering the baffle and contaminating the parts inside the baffle. However, each time the computer is used, it is necessary to control the driving structure in advance to open the opening of the ventilation hole, and then close it again after each use. The operation process is relatively cumbersome. Utility Model Content

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A dust prevention device for an air inlet of a computer, comprising:

[0006] A chassis, wherein a pair of side panels are connected to the left side of the chassis at positions close to the air inlet, a frame is slidably connected to the inner walls of the pair of side panels, a coarse-mesh woven fabric is connected to the inner wall of the frame, and five elastic ropes are connected to the inner wall of the frame near the back side of the coarse-mesh woven fabric;

[0007] A reset mechanism is provided below the frame;

[0008] A limiting mechanism is arranged above the frame.

[0009] In one possible implementation, the reset mechanism includes a reset spring connected to the bottom surface of the inner wall of the side plate, the top end of the reset spring is connected to the bottom plate, a connecting rod is connected below the bottom plate and inside the reset spring, and the end of the connecting rod passes through the bottom of the side plate.

[0010] In a possible implementation manner, a through hole is formed at the bottom of the side plate, and the end of the connecting rod passes through the interior of the through hole.

[0011] In a possible implementation manner, a connecting plate is connected to the end of the connecting rod.

[0012] In a possible implementation, the limiting mechanism includes a first limiting hole opened at the top of the longer arm of the connecting plate, and a second limiting hole at the top of the side plate, and the interiors of the first limiting hole and the second limiting hole both penetrate the connected limiting plate.

[0013] In a possible implementation manner, the limiting plate and the connecting plate are both configured to be L-shaped.

[0014] In a possible implementation manner, a sealing strip is connected to the back side of the frame.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. The coarse-mesh cloth can effectively filter dust and particles in the air. When the dust inside the coarse-mesh cloth needs to be cleaned, just remove the limit plate, then pull the elastic rope to the rear side, and use the elastic force of the elastic rope to hit the coarse-mesh cloth to clean the dust inside the coarse-mesh cloth. The operation steps are simple. By installing the coarse-mesh cloth at the air inlet position of the chassis, the dust-proof effect can be achieved whether the computer needs to be used or not, which eliminates the need to drive the structure to close or open the opening of the ventilation hole, thereby increasing practicality.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The embodiments of the present application solve the problems in the prior art by providing a computer air inlet dust prevention device.

[0026] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0027] Embodiment 1:

[0028] The specific structure of this embodiment is as follows: Figure 1-Figure 3 As shown, a computer air inlet dust prevention device comprises:

[0029] The chassis 1, a pair of side panels 4 are connected to the position of the left side of the chassis 1 near the air inlet, the inner walls of the pair of side panels 4 are slidably connected to a frame 9, the inner wall of the frame 9 is connected to a coarse-mesh fabric 5, and the inner wall of the frame 9 is connected to five elastic ropes 10 near the back side of the coarse-mesh fabric 5. When it is necessary to clean the dust inside the coarse-mesh fabric 5, just remove the limit plate 2, then pull the elastic rope 10 to the rear side, and use the elastic force of the elastic rope 10 to hit the coarse-mesh fabric 5 to clean the dust inside the coarse-mesh fabric 5;

[0030] A reset mechanism is provided below the frame 9. When the limit plate 2 is removed, the connection plate 3 loses its restriction, and the reset spring 11 loses its restriction, pushing the bottom plate 7 up and pushing the frame 9 out, making it easier for the staff to take the frame 9. After the dust inside the coarse-mesh fabric 5 is cleaned, the frame 9 is slid into the side plates 4 on both sides, and the reset spring 11 is squeezed at the same time.

[0031] A limiting mechanism is provided above the frame 9. The frame 9 is limited by the limiting mechanism. At the same time, the bottom plate 7 descends, squeezing the reset spring 11 and driving the connecting plate 3 to descend. At this time, it is convenient to insert the limiting plate 2 into the first limiting hole 12 and the second limiting hole 13 to complete the limiting of the frame 9.

[0032] In some examples, the reset mechanism includes a reset spring 11 connected to the bottom surface of the inner wall of the side panel 4, the top of the reset spring 11 is connected to the bottom plate 7, and a connecting rod 6 is connected below the bottom plate 7 and inside the reset spring 11. The end of the connecting rod 6 passes through the bottom of the side panel 4, and the frame 9 is slid into the side panels 4 on both sides. At the same time, the bottom plate 7 descends, squeezing the reset spring 11 and driving the connecting plate 3 to descend. When the connecting plate 3 loses its restriction, the reset spring 11 loses its restriction, pushing the bottom plate 7 to lift, and pushing the frame 9 out, making it easier for the staff to take the frame 9.

[0033] In some examples, a through hole 14 is opened at the bottom of the side plate 4, and the end of the connecting rod 6 passes through the interior of the through hole 14. By setting the connecting rod 6, a force transmission effect is achieved, and the bottom plate 7 descends, squeezing the reset spring 11 while driving the connecting plate 3 to descend; when the limit plate 2 is removed, the connecting plate 3 loses its restriction, and then the reset spring 11 loses its restriction, pushing the bottom plate 7 to rise.

[0034] In some examples, the end of the connecting rod 6 is connected to a connecting plate 3. When it is necessary to clean the dust inside the coarse-mesh fabric 5, only the limiting plate 2 needs to be removed. When the limiting plate 2 is removed, the connecting plate 3 loses its restriction, and the reset spring 11 loses its restriction, pushing the bottom plate 7 to lift and push out the frame 9, making it easier for the staff to take the frame 9. After the dust inside the coarse-mesh fabric 5 is cleaned, the frame 9 is slid into the side plates 4 on both sides, and the limiting plate 2 is inserted into the first limiting hole 12 and the second limiting hole 13 to complete the limitation of the frame 9, and also squeeze the reset spring 11 to prevent it from bouncing up.

[0035] In some examples, the limiting mechanism includes a first limiting hole 12 opened at the top of the longer arm of the connecting plate 3, and a second limiting hole 13 at the top of the side plate 4. The interiors of the first limiting hole 12 and the second limiting hole 13 are both connected through the limiting plate 2. Inserting the limiting plate 2 into the first limiting hole 12 and the second limiting hole 13 is beneficial for limiting the frame 9 to prevent it from bouncing up on the one hand, and is beneficial for limiting the connecting plates 3 on both sides on the other hand.

[0036] In some examples, the limiting plate 2 and the connecting plate 3 are both configured to be L-shaped.

[0037] In some examples, a sealing strip 8 is connected to the back side of the frame 9. The sealing strip 8 is provided to increase the sealing effect between the frame 9 and the chassis 1 and prevent dust from entering the air inlet of the chassis 1. After the dust inside the coarse-mesh fabric 5 is cleaned, the frame 9 is slid into the side panels 4 on both sides, and at the same time, the sealing strip 8 on the back side of the frame 9 is in contact with the chassis 1 to achieve a sealing and dustproof effect.

[0038] By adopting the above technical solution:

[0039] The coarse-mesh fabric 5 can effectively filter dust and particles in the air, and when the dust inside the coarse-mesh fabric 5 needs to be cleaned, the limiting plate 2 only needs to be removed, and then the elastic rope 10 is pulled to the rear side, and the elastic force of the elastic rope 10 is used to hit the coarse-mesh fabric 5 to clean the dust inside the coarse-mesh fabric 5. The operation steps are simple. By installing the coarse-mesh fabric 5 at the air inlet position of the chassis 1, the dust-proof effect can be achieved regardless of whether the computer needs to be used or not, and the processing step of driving the structure to close or open the opening of the ventilation hole is eliminated, thereby increasing practicality.

[0040] When the limit plate 2 is removed, the connection plate 3 loses its restriction, and the return spring 11 loses its restriction, pushing the bottom plate 7 to lift up and ejecting the frame 9, making it easier for the staff to take the frame 9 and saving replacement time.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
