Description

Technical Field

[0001] The utility model relates to the technical field of dustproof nets, and more specifically, to a combined dustproof net for an electrical appliance chassis. Background Art

[0002] During operation, the combined electrical chassis will inhale a large amount of air for heat dissipation, which may also bring in dust and impurities; the dustproof net can effectively block these dust and impurities from entering the chassis, protecting the electrical components in the chassis from dust.

[0003] The traditional combined electrical chassis dust screen has the following shortcomings: the traditional combined electrical chassis dust screen should be installed at the air inlet and outlet of the chassis fan to ensure that it can effectively block dust from entering the chassis. Most of the four ends of the dust screen are fixed to the outside of the electrical chassis by bolts. When the dust screen needs to be disassembled and cleaned, the bolts at the four ends need to be removed, which is inconvenient. Therefore, it needs to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a combined dustproof net for an electrical appliance chassis, which has the advantage of being easy to use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a combined dustproof net for an electrical appliance chassis, comprising a frame, with jacks provided on both sides of the frame, a rectangular block movably installed inside the jack, a rear end of the rectangular block extending to the outside of the frame, movable grooves provided on both sides of the rear end of the rectangular block, and a sloped block movably installed inside the movable groove.

[0006] As a preferred technical solution of the utility model, a dustproof net is welded on the inner side of the frame, and through holes are evenly opened on the surface of the dustproof net, and the through holes are distributed in a mesh structure array.

[0007] As a preferred technical solution of the utility model, limiting grooves are provided on both sides of the movable groove, and limiting blocks located inside the limiting grooves are fixedly installed at both ends of the inclined block.

[0008] As a preferred technical solution of the utility model, a magnetic attraction plate is fixedly installed on the front side of the rectangular block, and the magnetic attraction plate is located on the inner side of the frame.

[0009] As a preferred technical solution of the utility model, a telescopic spring is elastically installed at the bottom of the movable groove, and the telescopic spring is located on the inner side of the inclined surface block.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model passes the rear end of the rectangular block through the insertion hole so that the inclined block squeezes the telescopic spring. When the rear end of the rectangular block is fully inserted into the inside of the insertion hole, the telescopic spring releases elastic potential energy to push the inclined block to move outward, thereby connecting the magnetic plate with the frame. Compared with the traditional combined electrical chassis dust net, this combined electrical chassis dust net is installed on the outside of the chassis by combining the magnetic plate, the rectangular block and the frame, which is easy to use.

[0012] 2. The utility model arranges the through holes into a mesh structure, so that the through holes are distributed in a mesh structure, which can provide a larger ventilation area and effectively block the entry of dust. Compared with the traditional combined electrical chassis dust net, this combined electrical chassis dust net usually has higher dust prevention efficiency and better heat dissipation performance, and is easy to use.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5As shown, the utility model provides a combined dustproof net for an electrical appliance chassis, including a frame 1, with jacks 3 provided on both sides of the frame 1, a rectangular block 4 movably installed inside the jack 3, a rear end of the rectangular block 4 extending to the outside of the frame 1, movable grooves 6 provided on both sides of the rear end of the rectangular block 4, and a slope block 7 movably installed inside the movable groove 6.

[0021] When it is necessary to install the dust screen 2 on the outside of the chassis, first pass the rear end of the rectangular block 4 through the hole 3. At this time, the inclined block 7 is subjected to the extrusion force and moves toward the inside of the movable groove 6, so that the inclined block 7 squeezes the telescopic spring 8, causing the telescopic spring 8 to deform. At the same time, the inclined block 7 drives the limiting block 10 to move inside the limiting groove 9, thereby limiting the inclined block 7 and preventing the inclined block 7 from escaping from the inside of the movable groove 6. When the rear end of the rectangular block 4 is fully inserted into the inside of the hole 3, the telescopic spring 8 releases its elastic potential energy to push the inclined block 7 to move outward, thereby connecting the magnetic plate 5 with the frame 1, and then the magnetic plate 5 is attached to the top of the chassis shell, thereby connecting the chassis with the dust screen 2. When it is necessary to remove the dust screen 2, just press the inclined block 7 to shrink the inclined block 7 to the inside of the movable groove 6, thereby pulling the frame 1 outward.

[0022] By passing the rear end of the rectangular block 4 through the socket 3, the inclined block 7 squeezes the telescopic spring 8. When the rear end of the rectangular block 4 is fully inserted into the interior of the socket 3, the telescopic spring 8 releases elastic potential energy to push the inclined block 7 to move outward, thereby connecting the magnetic plate 5 with the frame 1. Compared with the traditional combined electrical chassis dust net, this combined electrical chassis dust net is installed on the outside of the chassis by combining the magnetic plate 5, the rectangular block 4 and the frame 1, which is easy to use.

[0023] A dustproof net 2 is welded to the inner side of the frame 1 , and through holes 11 are evenly formed on the surface of the dustproof net 2 . The through holes 11 are distributed in a mesh structure array.

[0024] The mesh structure is composed of multiple tiny holes, which form a dense breathable network as a whole. Compared with a single large-area opening, the mesh structure can provide more breathable channels while maintaining the same coverage area, thereby increasing the ventilation area. When air passes through the mesh structure, due to the large number of holes and their uniform distribution, the air can flow more smoothly, reducing resistance and eddy currents, and further improving ventilation efficiency. The holes in the mesh structure usually have a specific size range, which are designed according to the size of the dust particles that need to be blocked. Since the diameter of dust particles is usually larger than the diameter of the holes, when air carries dust particles through the mesh structure, the dust particles will be blocked on the outside by the holes and cannot enter the internal space.

[0025] By setting the through holes 11 into a mesh structure and distributing the through holes 11 in a mesh structure, a larger ventilation area can be provided and dust can be effectively blocked from entering. Compared with traditional combined electrical chassis dust nets, this combined electrical chassis dust net usually has higher dust-proof efficiency and better heat dissipation performance and is easy to use.

[0026] Wherein, limiting grooves 9 are provided on both sides of the movable groove 6 , and limiting blocks 10 located inside the limiting grooves 9 are fixedly installed on both ends of the inclined surface block 7 .

[0027] The inclined plane block 7 drives the limiting block 10 to move inside the limiting groove 9 , thereby limiting the inclined plane block 7 and preventing the inclined plane block 7 from escaping from the inside of the movable groove 6 .

[0028] A magnetic attraction plate 5 is fixedly mounted on the front side of the rectangular block 4 , and the magnetic attraction plate 5 is located on the inner side of the frame 1 .

[0029] The magnetic plate 5 is attached to the upper part of the chassis shell, so as to connect the chassis with the dustproof net 2, which is convenient for personnel to use.

[0030] A telescopic spring 8 is elastically installed at the bottom of the movable groove 6 , and the telescopic spring 8 is located on the inner side of the inclined surface block 7 .

[0031] The inclined plane block 7 is subjected to the extrusion force and moves toward the inside of the movable groove 6, so that the inclined plane block 7 squeezes the telescopic spring 8, causing the telescopic spring 8 to deform. When the rear end of the rectangular block 4 is fully inserted into the inside of the socket 3, the telescopic spring 8 releases its elastic potential energy to push the inclined plane block 7 to move outward, thereby connecting the magnetic attraction plate 5 with the frame 1.

[0032] The working principle and use process of this utility model:

[0033] When it is necessary to install the dust screen 2 on the outside of the chassis, first pass the rear end of the rectangular block 4 through the hole 3. At this time, the inclined block 7 is subjected to the extrusion force and moves toward the inside of the movable groove 6, so that the inclined block 7 squeezes the telescopic spring 8, causing the telescopic spring 8 to deform. At the same time, the inclined block 7 drives the limiting block 10 to move inside the limiting groove 9, thereby limiting the inclined block 7 and preventing the inclined block 7 from escaping from the inside of the movable groove 6. When the rear end of the rectangular block 4 is fully inserted into the inside of the hole 3, the telescopic spring 8 releases its elastic potential energy to push the inclined block 7 to move outward, thereby connecting the magnetic plate 5 with the frame 1, and then the magnetic plate 5 is attached to the top of the chassis shell, thereby connecting the chassis with the dust screen 2. When it is necessary to remove the dust screen 2, just press the inclined block 7 to shrink the inclined block 7 to the inside of the movable groove 6, thereby pulling the frame 1 outward.

[0034] The mesh structure is composed of multiple tiny holes, which form a dense breathable network as a whole. Compared with a single large-area opening, the mesh structure can provide more breathable channels while maintaining the same coverage area, thereby increasing the ventilation area. When air passes through the mesh structure, due to the large number of holes and their uniform distribution, the air can flow more smoothly, reducing resistance and eddy currents, and further improving ventilation efficiency. The holes in the mesh structure usually have a specific size range, which are designed according to the size of the dust particles that need to be blocked. Since the diameter of dust particles is usually larger than the diameter of the holes, when air carries dust particles through the mesh structure, the dust particles will be blocked on the outside by the holes and cannot enter the internal space.
