Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinet design, in particular to a waterproof and moisture-proof power distribution cabinet. Background Art

[0002] The power distribution cabinet is mainly used for distributing and controlling electricity. It can receive the main power supply and distribute the electricity to different circuits or equipment. Since moisture and humidity can easily damage the equipment, causing equipment failure and electrical equipment short circuit, a waterproof and moisture-proof power distribution cabinet is required. However, in the use of common waterproof and moisture-proof power distribution cabinets, the wiring harness and the cabinet body are usually sealed by a sealing ring, but when there are fewer wiring harnesses, the sealing effect of the sealing ring is limited, so the sealing ring needs to be replaced frequently. Utility Model Content

[0003] The purpose of the utility model is to provide a waterproof and moisture-proof distribution cabinet in order to solve the above-mentioned problem. By moving the internal gas of the adaptive structure to the interior of the airbag, the airbag continuously forms a fitting seal with the wiring harness, thereby facilitating the sealing of multiple wiring harnesses.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] A waterproof and moisture-proof power distribution cabinet comprises a cabinet body, a sponge, a ventilation plate and a sealing strip, wherein a sealing structure is arranged on the bottom side of the cabinet body, a ventilation plate is fixedly arranged on the lower end of the interior of the cabinet body, an adaptive structure is arranged on the lower end of the interior of the cabinet body, and an air bag is fixedly arranged on the lower end of the interior of the cabinet body.

[0006] The adaptive structure includes an air cylinder and a piston, an air pipe is fixedly connected to one side of the interior of the air cylinder body, one end of the air pipe is connected to the airbag, a return spring is fixedly connected between the piston and the air cylinder, a limiting rod is fixedly provided at the front end of the piston, a connecting rod is fixedly provided on one side of the limiting rod, and a baffle is fixedly provided on the bottom side of the connecting rod.

[0007] Furthermore, the limiting rod is slidably arranged inside the cabinet.

[0008] Furthermore, the sponge is fixedly arranged inside the cabinet at an upper end close to the baffle, and the ventilation plate is rotatably arranged on the inner bottom surface of the cabinet.

[0009] Furthermore, a connection frame is provided on the front side of the cabinet, and the sealing strip is connected to the outside of the connection frame.

[0010] Furthermore, the piston is slidably arranged inside the gas cylinder.

[0011] Furthermore, the baffle is slidably arranged inside the cabinet.

[0012] Furthermore, the sealing structure comprises a cover plate, a support rod is rotatably arranged inside the cover plate, and the cover plate is rotatably arranged on the bottom side of the cabinet.

[0013] Furthermore, a limiting ball is fixedly provided on one side of the support rod.

[0014] With the above structure, when using the device, first, the upper limit ball of the sealing structure is inserted into the airbag, and then the adaptive structure pulls the piston through the return spring of the air cylinder, thereby pushing the gas inside the air cylinder into the airbag, and then the airbag clamps the limit ball, and then the limit ball seals the wiring harness opening through the cover plate on the support rod. When the wiring harness is to be installed on the distribution box, the cover plate is opened, and then the wiring harness passes through the airbag and enters the interior of the distribution cabinet, so that the wiring harness squeezes the airbag. At the same time, the airbag continuously adaptively fits with the wiring harness through the gas inside the air cylinder to form a seal. At the same time, when the airbag is squeezed, the gas enters the interior of the air cylinder to squeeze the piston, and then the piston drives the baffle and the breathable plate to form a misalignment through the connecting rod on the limit rod. The gas can dissipate heat through the breathable plate, and the gas absorbs water through the sponge when entering the distribution cabinet. Finally, when the water absorption of the sponge deteriorates, the sponge is replaced by opening the ventilation plate.

[0015] In summary, the beneficial effect of the utility model is that the piston is pulled by the reset spring inside the air cylinder, so that the gas enters the airbag through the air pipe, which facilitates the airbag to continuously fit with the wiring harness to form a seal. Different numbers of wiring harnesses can be fitted and sealed, which improves the waterproofness of the distribution cabinet to a certain extent. At the same time, a sealing strip is installed on the distribution cabinet, which is convenient for improving the sealing between the cabinet body and the cabinet door when the cabinet door is closed, thereby further improving the waterproofness of the cabinet body.

[0029] The adaptive structure 6 includes a cylinder 601 and a piston 602. An air pipe 604 is fixedly connected to one side of the cylinder 601. One end of the air pipe 604 is connected to the airbag 3. A return spring 603 is fixedly connected between the piston 602 and the cylinder 601. The adaptive structure 6 pulls the piston 602 through the return spring 603 of the cylinder 601, thereby pushing the gas inside the cylinder 601 into the airbag 3, so that the airbag 3 is continuously fitted and sealed. The front end of the piston 602 is fixedly provided with a limited The limiting rod 607 has a connecting rod 605 fixedly disposed on one side thereof, and a baffle 606 fixedly disposed on the bottom side of the connecting rod 605. When the wiring harness is installed to squeeze the airbag 3, the internal gas of the airbag 3 enters into the air cylinder 601 through the air pipe 604, thereby squeezing the piston 602. Then the piston 602 drives the baffle 606 and the air permeable plate 7 to form a misalignment through the connecting rod 605 on the limiting rod 607. The gas can dissipate heat through the air permeable plate 7, and absorb water through the sponge 5 when the gas enters the distribution cabinet.

[0030] Furthermore, the limiting rod 607 is slidably disposed inside the cabinet 1 , and the moving position of the piston 602 is conveniently limited by the limiting rod 607 .

[0031] Furthermore, the sponge 5 is fixedly arranged inside the cabinet 1 near the upper end of the baffle 606, and the gas can pass through the sponge 5 through the breathable plate 7 to enter the cabinet 1. The external moisture is adsorbed by the sponge 5 to prevent moisture from entering the cabinet 1. The ventilation plate 4 is rotatably arranged on the inner bottom surface of the cabinet 1. The sponge 5 can be replaced by flipping open the ventilation plate 4.

[0032] Furthermore, a connection frame 8 is provided on the front side of the cabinet 1 , and the sealing strip 9 is connected to the outside of the connection frame 8 . The sealing strip 9 facilitates the formation of a seal between the connection frame 8 and the cabinet door to prevent moisture from entering the interior of the cabinet 1 .

[0033] Furthermore, the piston 602 is slidably disposed inside the gas cylinder 601, and the piston 602 squeezes the gas cylinder 601 to facilitate pushing the gas inside the gas cylinder 601, so that the gas can enter the airbag 3, making it convenient for the airbag 3 to expand and fit with the wiring harness.

[0034] Furthermore, the baffle 606 is slidably disposed inside the cabinet 1 , and the movement of the baffle 606 facilitates the control of the air permeable plate 7 to move gas.

[0035] Furthermore, the sealing structure 2 includes a cover plate 201, and a support rod 202 is rotatably arranged inside the cover plate 201. The cover plate 201 is rotatably arranged on the bottom side of the cabinet 1. When not in use, the wiring harness port on the cabinet 1 is sealed by the cover plate 201 to prevent the interior from being corroded by moisture.

[0036] Furthermore, a limiting ball 203 is fixedly provided on one side of the support rod 202, and the limiting ball 203 is convenient for inserting into the airbag 3 for connection, thereby facilitating the cover plate 201 on the limiting ball 203 to close and seal the wiring harness port.

[0037] With the above structure, when using the device, first, the upper limit ball 203 of the sealing structure 2 is inserted into the airbag 3, and then the adaptive structure 6 pulls the piston 602 through the return spring 603 of the air cylinder 601, thereby pushing the gas inside the air cylinder 601 into the airbag 3, and then the airbag 3 clamps the limit ball 203, and then the limit ball 203 seals the wiring harness port through the cover plate 201 on the support rod 202. When the wiring harness is to be installed on the distribution box, the cover plate 201 is opened, and then the wiring harness passes through the airbag 3 and enters the interior of the distribution cabinet, so that The wiring harness squeezes the airbag 3, and the airbag 3 continuously adapts to the wiring harness through the gas inside the air cylinder 601 to form a seal. At the same time, when the airbag 3 is squeezed, the gas enters the interior of the air cylinder 601 to squeeze the piston 602, and then the piston 602 drives the baffle 606 and the breathable plate 7 to form a misalignment through the connecting rod 605 on the limit rod 607. The gas can dissipate heat through the breathable plate 7. When the gas enters the distribution cabinet, it absorbs water through the sponge 5. Finally, when the water absorption of the sponge 5 deteriorates, the sponge 5 is replaced by opening the ventilation plate 4.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
