DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model.

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0031] like Figure 1-3 and Figure 8 As shown, the utility model provides a portable dustproof control cabinet, comprising a cabinet body and a cabinet door 1 rotatably arranged on one side of the outer wall of the cabinet body, a support block 2 is arranged on one side of the inner wall of the cabinet door 1, guide rails 3 are symmetrically arranged on both sides of the top of the support block 2, and a mounting block 4 with the same sliding connection is arranged between the two guide rails 3, a fan 5 is detachably connected to the outer wall of the mounting block 4 away from the cabinet door 1, and a through hole 6 for placing filter cotton is opened on the outer wall of the mounting block 4 on one side of the fan 5; a plurality of ventilation holes 7 are opened on the outer wall of the cabinet door 1, and when the mounting block 4 is located at the top of the support block 2, part of the ventilation holes 7 are located on one side of the through hole 6, and the mounting block 4 is detachably connected to the guide rail 3 through a limiting mechanism.

[0032] Specifically, when the cabinet door 1 is installed on the cabinet, the support block 2 is located inside the cabinet. When heat dissipation is required, the fan 5 starts to work, and the air outside the cabinet is sucked into the cabinet through multiple vents 7 and through holes 6, and then the high-temperature air is discharged from the remaining outlets of the cabinet to complete the heat dissipation of the cabinet. The filter cotton is installed inside the through hole 6. When the fan 5 is working, the filter cotton filters the air sucked by the fan 5 to prevent dust from entering the interior of the cabinet, thereby ensuring the safety of various components in the cabinet. After the fan 5 and the filter cotton have been working for a long time, too many impurities are accumulated on the filter cotton, and the filter cotton needs to be replaced. When the filter cotton is replaced, the mounting block 4 is realigned with the two guide rails 3, and then the mounting block 4 is inserted between the two guide rails 3 from top to bottom until the bottom of the mounting block 4 contacts the top of the support block 2. At this time, the limiting mechanism is opened to complete the installation of the mounting block 4, thereby completing the replacement of the filter cotton without disassembling the fan 5, thereby ensuring the convenience of the device.

[0033] When the filter cotton is replaced, since the fan 5 is fixed on the mounting block 4, it is only necessary to pull the mounting block 4 out of the two guide rails 3 and replace the filter cotton inside the through hole 6. There is no need to remove the entire fan 5 and then replace the filter cotton, which simplifies the work process and ensures the convenience and practicality of the device.

[0034] like Figure 4 As shown, in one embodiment, the fan 5 includes a shell 51, a rotatably connected fan blade 52 is provided on the inner side of the shell 51, a protective cover 53 is provided on the outer wall of the shell 51 close to the through hole 6, and the support block 2 and the two guide rails 3 are both L-shaped.

[0035] Specifically, when the filter cotton is placed inside the through hole 6, the filter cotton is located between the inner wall of the cabinet door 1 and the protective cover 53. The protective cover 53 is used to prevent the filter cotton from contacting the fan blades 52, thereby ensuring the safety of the fan 5 when working. The support block 2 and the two guide rails 3 are both L-shaped, so that the mounting block 4 is fixed between the two guide rails 3, and one side of the inner wall of the mounting block 4 is in contact with the inner wall of the cabinet door 1, so that the cabinet door 1 cooperates with the protective cover 53 to position the filter cotton in the through hole 6, thereby ensuring the filtering effect of the filter cotton on the air; optionally, the guide rail 3 and the cabinet door 1 are detachably connected.

[0036] like Figure 6As shown, in one embodiment, a placement groove 8 is opened on the outer wall of the support block 2 at one side of the through hole 6, and rotationally connected pressing plates 9 are symmetrically provided on both sides of the inner wall of the placement groove 8.

[0037] Optionally, the placement groove 8 is arranged on the side of the outer wall of the support block 2 away from the fan 5. When fixing the filter cotton, the filter cotton can be placed inside the placement groove 8. The step formed by the placement groove 8 and the through hole 6 serves as a blocking effect on one side of the filter cotton. Then the pressing plate 9 is rotated to rotate toward the filter cotton to squeeze and fix the other side of the filter cotton. When the mounting block 4 is placed inside the two guide rails 3, the inner wall of the cabinet door 1 can block the pressing plate 9, thereby completing the positioning of the filter cotton and avoiding displacement of the filter cotton during filtering, thereby further ensuring the filtering effect of the filter cotton.

[0038] like Figure 5 As shown, in one embodiment, the limiting mechanism includes a slide groove 10 symmetrically opened on both sides of the outer wall of the mounting block 4, a push rod 11 slidably connected is provided in the slide groove 10, and the push rod 11 is elastically connected to the inner wall of the slide groove 10 through a spring 12, and a limiting hole 18 matching the push rod 11 is opened on one side of the outer wall of the guide rail 3, and when the mounting block 4 is located at the top of the support block 2, the limiting hole 18 is aligned with the slide groove 10; an opening is opened on one side of the top of the slide groove 10, and a slidingly connected latch 13 is provided in the opening, and one end of the latch 13 extends above the support block 2, and a groove 14 matching the latch 13 is opened on the top of the push rod 11, and when the push rod 11 is completely located inside the slide groove 10, the position of the latch 13 is aligned with the position of the groove 14.

[0039] Specifically, when the mounting block 4 is installed between the two guide rails 3, the push rod 11 is completely located inside the slide groove 10, and the latch 13 is located inside the groove 14, thereby fixing the relative positions of the push rod 11 and the slide groove 10. When the mounting block 4 moves, the push rod 11 moves with the mounting block 4. When the bottom of the mounting block 4 contacts the top of the support block 2, it means that the mounting block 4 is in place at this time. At this time, the slide groove 10 is aligned with the position of the limiting hole 18, and the latch 13 is pulled up for a distance so that the latch 13 is no longer located inside the groove 14, and the limit on the push rod 11 is cancelled. At this time, the spring 12 pushes the push rod 11 to move toward the outside of the slide groove 10, so that the push rod 11 moves to the inside of the limiting hole 18, thereby fixing the position of the mounting block 4 and the guide rail 3 to avoid wind. The fan 5 shakes during movement, which ensures the stability of the fan 5 during operation. When the mounting block 4 needs to be removed, the push rod 11 can be pushed to move toward the inside of the slide slot 10, and the groove 14 moves with the push rod 11. When the groove 14 moves to the bottom of the latch 13, the latch 13 falls into the inside of the groove 14 due to the effect of gravity, thereby fixing the position of the push rod 11 and the slide slot 10. At this time, the push rod 11 is no longer located inside the limiting hole 18, and the mounting block 4 can be directly pulled out from above the two guide rails 3 to complete the replacement of the filter cotton, thereby ensuring the convenience of the device. The utility model cooperates with the push rod 11, the latch 13 and the groove 14 to achieve positioning between the mounting block 4 and the guide rail 3, thereby avoiding shaking of the fan 5 during operation and ensuring the stability of the fan 5 during operation.

[0040] like Figure 2 and Figure 7 As shown, in one embodiment, a protective plate 15 is detachably connected to one side of the outer wall of the cabinet door 1, and the protective plate 15 is located on one side of the plurality of vents 7. A rotatably connected partition 16 is provided on one side of the inner wall of the protective plate 15. A bolt 17 is detachably connected to the outer wall of the protective plate 15 on one side of the partition 16. The partition 16, the protective plate 15 and the cabinet door 1 cooperate to form a sealed cavity.

[0041] When in use, the protective plate 15 is located on one side of the multiple vents 7 to prevent rainwater from entering the cabinet through the vents 7, further ensuring the safety of the control cabinet. When the fan 5 is not needed for heat dissipation, the bolt 17 can be removed so that the bolt 17 no longer blocks the partition 16. At this time, the partition 16 is rotated downward so that the partition 16, the protective plate 15 and the cabinet door 1 cooperate to form a sealed cavity. The cavity is located on one side of the multiple vents 7, thereby sealing the vents 7 to prevent external air from entering the cabinet through the vents 7 at this time. At this time, the filter cotton does not need to perform filtering work, thereby extending the service life of the filter cotton; when the fan 5 starts to work, the partition 16 can be rotated to restore it to its original position, and the bolt 17 can be reinstalled. The bolt 17 blocks the partition 16 to prevent the partition 16 from rotating downward. At this time, the protective plate 15 can perform ventilation work; optionally, a block for blocking the partition 16 is provided on one side of the bottom of the protective plate 15.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
