Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0021] See also Figure 1-4 As shown, the utility model provides a technical solution:

[0022] Embodiment 1: An anti-electric shock low-voltage withdrawable integrated switch cabinet, comprising a low-voltage withdrawable integrated switch cabinet body 1, an inner compartment 11 is provided on the front side of the low-voltage withdrawable integrated switch cabinet body 1, a pull-out electrical installation box 2 is movably arranged in the inner compartment 11, an alarm light is fixedly installed on the inner wall of the inner compartment 11, an elastic telescopic rod is fixedly provided at the bottom of the alarm light, a moving wheel is fixedly connected to the lower end of the telescopic rod, and the moving wheel rolls along the bottom of the pull-out electrical installation box 2, the alarm light is electrically connected to the pull-out electrical installation box 2 through the elastic telescopic rod and the moving wheel, when the pull-out electrical installation box 2 has a leakage, the alarm light is on, and a prompt is given to the outside to prevent people from getting an electric shock. No further description is given here. The low-voltage withdrawable integrated switch cabinet body 1 on both sides of the inner compartment 11 is symmetrically fixed with the moving wheels. A guide rail 3 is connected, and a sealing door 4 is movably arranged between the two guide rails 3. A handle 41 is fixedly arranged on the front side of the sealing door 4, and a sealing ring 5 is fixedly connected to the edge position of the rear side of the sealing door 4. The sealing ring 5 fits with the front side wall of the low-voltage withdrawable integrated switch cabinet body 1. Through the sealing ring 5, the connection gap between the low-voltage withdrawable integrated switch cabinet body 1 and the sealing door 4 can be sealed. A first inclined surface 42 is arranged at the bottom of the sealing door 4, and a pressing seat 6 is elastically connected to the inner wall of the lower part of the guide rail 3 through a spring 7. The provided pressing seat 6 is used to squeeze the sealing door 4, so that the sealing ring 5 can effectively fit with the low-voltage withdrawable integrated switch cabinet body 1, so that the opening of the inner compartment 11 can be effectively sealed through the sealing door 4, which is beneficial to extend the service life of the cabinet. In order to extend the service life of the electrical appliances inside the pull-out electrical installation box 2, a limiting slider is arranged on the front side of the clamping seat 6, and the limiting slider moves along the limiting slide groove opened inside the guide rail 3 to limit the clamping seat 6 and prevent the clamping seat 6 from detaching from the guide rail 3. The spring 7 is located in the guide rail 3, and the front end of the spring 7 is fixedly connected to the guide rail 3, and the rear end of the spring 7 is fixedly connected to the clamping seat 6. A second inclined surface 61 is arranged on the top of the clamping seat 6, and the second inclined surface 61 is connected with the first inclined surface 42 in cooperation with the first inclined surface 42, so that the sealing door 4 can drive the clamping seat 6 to move forward during the downward movement of the sealing door 4, and compress the spring 7, so that the sealing door 4 can move smoothly between the low-voltage pull-out integrated switch cabinet body 1 and the clamping seat 6. When personnel pull out the electrical installation box After the inspection is completed, the sealing door 4 can be pulled downward by holding the handle 41. At this time, the cooperation between the first inclined surface 42 and the second inclined surface 61 can squeeze the pressing seat 6, so that the pressing seat 6 moves forward to compress the spring 7. When the sealing door 4 is pulled downward to the lowest position, the opening of the inner chamber 11 can be closed by the sealing door 4. At this time, the spring 7 drives the pressing seat 6 to move backward, which can squeeze the sealing door 4, so that the sealing ring 5 on the rear side of the sealing door 4 effectively abuts on the low-voltage withdrawable integrated switch cabinet body 1, and the connection between the low-voltage withdrawable integrated switch cabinet body 1 and the sealing door 4 can be sealed by the sealing ring 5, so that the pull-out type electrical installation box 2 inside the inner chamber 11 can be effectively protected from dust.

[0023] Embodiment 2: The difference between this embodiment and embodiment 1 lies in that a locking bolt 31 is threadedly connected to the guide rail 3 on one side, and one end of the locking bolt 31 abuts against the sealing door 4. The sealing door 4 can be locked by the locking bolt 31 to prevent the sealing door 4 from moving easily. The rear side of the pressing seat 6 is rotatably connected with a roller 62 through an axle. A plurality of rollers 62 on the pressing seat 6 are arranged at equal intervals from top to bottom. The sliding friction between the sealing door 4 and the pressing seat 6 can be converted into rolling friction by the roller 62, so that it is more convenient for personnel to pull the sealing door 4 downward. In the process of closing the sealing door 4, the roller 62 on the pressing seat 6 can roll along the front side wall of the sealing door 4, making it easier for personnel to close the sealing door 4. When the sealing door 4 is closed, the locking bolt 31 abuts against the side wall of the sealing door 4 through the locking bolt 31, so that the sealing door 4 can be locked to prevent the sealing door 4 from moving upward easily.

[0024] Working principle: When in use, after the personnel have finished inspecting the pull-out electrical installation box 2, they can pull the sealing door 4 downward by holding the handle 41. At this time, the cooperation between the first inclined surface 42 and the second inclined surface 61 can squeeze the pressing seat 6, so that the pressing seat 6 moves forward to compress the spring 7. When the sealing door 4 is pulled down to the lowest position, the opening of the inner chamber 11 can be closed by the sealing door 4. At this time, the spring 7 drives the pressing seat 6 to move backward, which can squeeze the sealing door 4, so that the sealing ring 5 on the rear side of the sealing door 4 effectively abuts against the low-voltage pull-out integrated switch On the cabinet body 1, the connection between the low-voltage withdrawable integrated switch cabinet body 1 and the sealed door 4 can be sealed by a sealing ring 5, so that the pull-out type electrical installation box 2 inside the inner compartment 11 can be effectively protected from dust. In the process of closing the sealed door 4, the roller 62 on the clamping seat 6 can roll along the front side wall of the sealed door 4, making it easier for personnel to close the sealed door 4. When closing the sealed door 4, by tightening the locking bolt 31 so that the locking bolt 31 abuts against the side wall of the sealed door 4, the sealed door 4 can be locked to prevent the sealed door 4 from moving upward easily.
