Description

Technical Field

[0001] This utility model relates to the technical field of distribution box equipment, specifically a dustproof and moisture-proof distribution box. Background Technology

[0002] Distribution boxes are electrical equipment that are widely used, have high space utilization, occupy little space, and have environmental benefits.

[0003] Patent (CN221709265U) discloses a distribution box with a cooling device, including a distribution box body, a connecting pipe on the top of the distribution box body, a filter structure on the top of the connecting pipe, copper plates on both inner walls of the distribution box body, multiple heat-conducting fins on both inner walls of the distribution box body extending through the distribution box body, a heat dissipation cavity inside the distribution box body, protective structures on both sides of the distribution box body, and a sealed door hinged to the front of the distribution box body. In use, the multiple heat-conducting fins inside the distribution box body will guide the internal temperature of the distribution box body into the heat dissipation cavity. When the fan is turned on, the fan will guide the outside air into the heat dissipation cavity on the inner wall of the distribution box body through the connecting pipe, thereby cooling the inside of the distribution box body through the heat dissipation cavity and preventing the internal temperature of the distribution box body from becoming too high and damaging the service life of the components.

[0004] The power distribution box in the aforementioned patent uses a fan to drive outside air through a filter to cool the inside of the power distribution box. Although this can prevent dust, when the humidity of the outside environment is high, the moisture in the air will be directly transported into the power distribution box through the fan, making the internal components of the power distribution box prone to moisture. Summary of the Invention

[0005] The purpose of this utility model is to provide a dustproof and moisture-proof distribution box to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dustproof and moisture-proof distribution box, including a box body, a cooling chamber at the top of the box body, a centrifugal fan vertically arranged in the center of the cooling chamber, an air guide frame matching the centrifugal fan at the bottom of the inner wall of the cooling chamber, an air guide opening matching the air guide frame at the top of the box body, mounting plates symmetrically inserted on both sides of the centrifugal fan at the top of the cooling chamber, a plurality of filters and moisture-proof components vertically arranged at the bottom of the mounting plates, a plurality of first ventilation openings on both sides of the outer wall of the cooling chamber, and a plurality of second ventilation openings on the outer wall of the box body.

[0007] Furthermore, the mounting plate is provided with a handle on top, the filter screen and the moisture-proof component are arranged alternately, and the bottom of the inner wall of the cooling chamber is provided with a limiting block that matches the filter screen and the moisture-proof component.

[0011] Furthermore, a door is hinged to one side of the outer wall of the enclosure, and a digital display panel is provided on the outer wall of the door. The second ventilation opening is located on the outer wall of the door.

[0012] Furthermore, both the first and second ventilation openings are equipped with rain covers on their outer sides.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] 1. This utility model comprises a housing, a cooling chamber, a centrifugal fan, an air guide frame, an air vent, a mounting plate, a filter screen, and a moisture-proof component. When the centrifugal fan is activated, it draws outside air into the cooling chamber through the first vent. The outside air then passes through multiple filters and the moisture-proof component on the mounting plate, and is then propelled into the housing by the centrifugal fan. The centrifugal fan guides the outside air through the air guide frame, and the outside air enters the housing through the air vent, thus cooling the components inside the housing. The filter screen effectively removes dust from the outside air, and the moisture-proof component absorbs and dries moisture from the outside air, effectively reducing the humidity of the air entering the housing. This design effectively ensures both cooling and dust and moisture protection for the housing.

[0015] 2. In this utility model, the first mounting strip and the second mounting strip cooperate to build the installation space and position of the component inside the housing. When adjusting the position of the second mounting strip, the second mounting strip is pulled outward and pulled out of the slot on the surface of the first mounting strip. The limiting block and the slider move together to the inside of the slide groove. Then, the second mounting strip is adjusted up and down. The slider and the limiting block slide up and down along the slide groove. When the position of the second mounting strip is adjusted properly, the second mounting strip is pushed inward and inserted into the slot on the surface of the first mounting strip. The limiting block is located inside the limiting groove to provide limiting support. At this time, the insertion limiting and locking of the second mounting strip and the first mounting strip are realized. This can effectively realize the adjustment of the installation space and position of the component inside the housing, which can meet the installation needs of different components and effectively improve the applicability of the housing.

This effectively ensures that the housing 1 is cooled and dissipated while also being dustproof and moisture-proof.

[0032] The first mounting strip 103 and the second mounting strip 104 cooperate to build the mounting space and position of the component inside the housing 1. The slide groove 107 provides sliding guide space for the slider 105 and the limiting block 106 in the vertical direction, and the limiting groove 108 provides limiting space for the limiting block 106 in the horizontal direction. When adjusting the position of the second mounting strip 104, the second mounting strip 104 is pulled outward, and the second mounting strip 104 is pulled out of the slot on the surface of the first mounting strip 103. The limiting block 106 slides outward along the limiting groove 108. The limiting block 106 and the slider 105 move together to the inside of the slide groove 107. Then the second mounting strip 104 is adjusted vertically. Block 105 and limiting block 106 slide up and down along the slide groove 107. When the position of the second mounting strip 104 is properly adjusted, the second mounting strip 104 is pushed inward. The slider 105 and limiting block 106 enter the inner side of the limiting groove 108 from the slide groove 107. The second mounting strip 104 is inserted into the slot on the surface of the first mounting strip 103. The limiting block 106 is located inside the limiting groove 108 for limiting support. At this time, the insertion limiting and locking of the second mounting strip 104 and the first mounting strip 103 is realized. This can effectively realize the adjustment of the installation space and installation position of the components inside the housing 1, which is convenient to meet the installation requirements of different components and can effectively improve the applicability of the housing 1.
