[0002] The main purpose of using a draw-out switch cabinet is to dispatch electric energy, distribute the electric energy from a transformer or other power sources to each load, ensure the stability of power supply, and be equipped with corresponding protection functions. Mainly equipped with protection devices such as circuit breakers and fuses, it can quickly cut off the power supply in case of faults such as overload and short circuit, protect the safety of equipment and personnel, and ensure the safe, reliable and efficient distribution of electric energy.

[0003] In this regard, Chinese Patent Publication No. CN213367140U discloses a GCK draw-out low-voltage switch cabinet body. Through transparent tempered glass, when the camera moves up and down, it can shoot the states of electrical equipment on several drawers, without the need for people to manually open the drawers for viewing, and real-time monitoring can be carried out.

[0004] However, when the existing low-voltage draw-out switch cabinet body is specifically used, as can be seen from the above solution, there are still some problems: The draw-out switch cabinet body is used for adaptive allocation of electric power. Usually, the drawer after wiring needs to be taken out and regular maintenance is required. When the drawer is re-inserted into the switch cabinet after inspection, since it is difficult for the maintenance personnel to control the force, the wire connection in the drawer may be loosened by vibration, which may cause short-circuit faults or poor electrical contact, affecting the power supply of the switch cabinet.

It should be noted that the attached drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present utility model.

[0027] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, the low-voltage draw-out switch cabinet includes a switch buffer adjustment mechanism 1, and one end of the switch buffer adjustment mechanism 1 is fixedly connected to a wiring drawer 2;

[0028] The switch buffer adjustment mechanism 1 includes a first support plate 101. On both sides of the upper end of the first support plate 101, auxiliary fixing blocks 102 are fixedly connected. On the front of the auxiliary fixing blocks 102, convex block adjusting rods 103 are fixedly connected. In the middle of the front of the first support plate 101, a limit support rod 104 is fixedly connected. A adjusting slider 105 is slidably connected to the surface of the limit support rod 104. On both sides of the front of the adjusting slider 105, support sleeves 106 are fixedly connected through through holes. In the middle of the front of the adjusting slider 105, a second support plate 107 is fixedly connected. With the setting of the switch buffer adjustment mechanism 1 and the wiring drawer 2, after the wiring drawer 2 is installed and repaired and then put back into the switch cabinet, the speed of the inward movement of the wiring drawer 2 can be slowed down, thus avoiding the loosening of the internal wires of the wiring drawer 2 caused by the difficulty of the maintenance personnel to control the force, and further preventing a chain reaction from causing a short circuit or poor electrical contact, which affects the power supply.

[0029] Please refer to Figure 4 , the bottom of the front of the adjusting slider 105 is slidably connected to the surface of the limit support rod 104 through a through hole.

[0030] The adjusting slider 105 is provided with a circular through hole on its front bottom that is adapted to the diameter of the limit support rod 104, and the sliding direction of the adjusting slider 105 is limited by the limit support rod 104.

[0031] Please refer to Figure 4 , the surface of the support sleeve 106 is slidably connected to the surface of the convex block adjusting rod 103.

[0032] One end of the surface of the convex block adjusting rod 103 is made of rubber material, and there is a certain frictional resistance when the support sleeve 106 slides on the surface of the convex block adjusting rod 103.

[0033] Please refer to Figures 1 to 2 , the back of the first support plate 101 is fixedly connected to a switch cabinet body 3, and support handles 4 are fixedly connected to both sides of the back of the switch cabinet body 3.

[0034] The switch cabinet body 3 is equipped with a handle on its back, which is convenient for dragging the switch cabinet.

[0035] Please refer to Figures 1 to 2 , on the top and bottom of both sides of the switch cabinet body 3, air vent plates 5 are threadedly connected through threaded holes.

[0036] The air vent plates 5 can provide appropriate ventilation to the inside of the switch cabinet when the switch cabinet is not in use, avoiding the internal moisture of the switch cabinet from causing oxidation and corrosion of metal components, shortening the service life of the equipment, affecting its performance, and increasing the risk of leakage points.

[0037] Please refer to Figure 3, on both sides of the upper end of the switch cabinet body 3, top support shells 6 are fixedly connected through through grooves opened.

[0038] The top support shell 6 fixedly supports the cooling fan 7 at the top.

[0039] The inner bottom wall of the top support shell 6 is fixedly connected with a cooling fan 7.

[0040] Driving the cooling fan 7 can dissipate heat from the inside of the switch cabinet body 3, preventing the switch cabinet from overheating during operation and causing circuit failures, which may affect power supply.

[0041] Please refer to Figure 3 , on both sides of the inner top wall of the top support shell 6 near the middle, wind direction guiding plates 8 are fixedly connected. One side surface of the wind direction guiding plate 8 is fixedly connected with one inner wall of the switch cabinet body 3.

[0042] The wind direction guiding plate 8 guides the cold air blown out by the cooling fan 7. At the same time, on the side of the wind direction guiding plate 8 close to the wiring drawer 2, there are uniformly extending air blowing pipelines, which helps the air flow to be evenly distributed throughout the pipeline, avoiding local overheating or insufficient cooling.

[0043] Please refer to Figures 1 to 2 , at both ends of the bottom of both side surfaces of the switch cabinet body 3, auxiliary pulleys 9 are rotatably connected through the setting of rotating shafts.

[0044] The auxiliary pulley 9 facilitates the dragging of the switch cabinet, and at the same time, the auxiliary pulley 9 is used for convenient movement and deployment operations.

[0045] The working principle of the present utility model is:

[0046] Put the wiring drawer 2 into the switch cabinet body 3. The second support plate 107 drives the support sleeve 106 to move backward. The support sleeve 106 slides on the surface of the convex block adjusting rod 103 with frictional resistance, and the adjusting slider 105 slides and is limited on the limit support rod 104, so that the support sleeve 106 is hindered by the sliding, slowing down the speed of the wiring drawer 2 sliding into the switch cabinet body 3, reducing the vibration degree, and preventing the circuit from being loosened and affecting power supply.

[0047] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model; any ordinary technician in the industry can smoothly implement the present utility model according to what is shown in the accompanying drawings of the specification and what is described above; however, any minor changes, modifications and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are all equivalent embodiments of the present utility model; at the same time, any changes, modifications and equivalent variations made to the above embodiments based on the substantial technology of the present utility model still fall within the protection scope of the technical solution of the present utility model.
