[0028] In this way, horizontal busbars, vertical busbars and wire holes are set on the drawer cabinet contact box. The horizontal busbars are used to connect multiple drawer-type contact boxes 8 to achieve horizontal distribution of power, which is convenient for managing multiple power outputs. The vertical busbars are used to connect contact boxes 8 at different heights to achieve vertical distribution of power, which helps save space and improve the flexibility of wiring. The design of these two busbars makes the expansion and maintenance of the power system more convenient, and also helps to improve the transmission efficiency and safety of current. At the same time, the wire hole 63 is used for threading, so that the wires can enter and exit the contact box 8 in an orderly manner, keeping the internal wiring neat and orderly, which not only helps to reduce interference between wires, but also facilitates subsequent maintenance and inspection. The handle 7 allows the operator to easily pull out or push in the drawer-type contact box 8 for maintenance or replacement of parts. The handle 7 can reduce physical exertion during operation and improve work efficiency. The operating handle 9 is used to manually operate the switch or circuit breaker within the contact box 8, allowing for quick power cuts or other operations in an emergency. It provides a means of directly controlling electrical equipment. The operating panel is the interface through which users interact with the equipment and is typically equipped with control elements such as indicator lights, buttons, and knobs. It allows operators to intuitively monitor and control the status of the electrical system and make necessary settings and adjustments. These components are designed to improve the safety, reliability, flexibility, and user-friendliness of electrical systems. Working together, they make the installation, operation, maintenance, and expansion of electrical equipment more efficient and safer.
[0029] In some embodiments, please refer to Figures 1 to 5 The fixing mechanism 2 includes a locking assembly 21, which includes a slide rail 211, a second cylinder 213 and a limit block 214. The slide rail 211 is arranged on the cabinet body 5, and a plurality of limit holes 215 are provided on the slide rail 211. A slide groove 212 is provided on the cabinet housing 1. The second cylinder 213 is arranged on the cabinet housing 1 through the slide groove 212. The limit block 214 is arranged on the output shaft of the second cylinder 213. The fixing mechanism 2 also includes a rebound assembly 22, which includes a spring 221, a first cylinder 222, a spring pressure plate 223 and a rebound pad 224. The spring pressure plate 223 is arranged on the cabinet housing 1 The first cylinder 222 is arranged on the spring pressure plate 223, one side of the rebound pad 224 is fixedly connected to the output shaft of the first cylinder 222, and the other side of the rebound pad 224 is fixedly connected to the side of the cabinet 5 away from the drawer cabinet 4. The spring 221 is sleeved on the first cylinder 222, one end of the spring 221 abuts against the rebound pad 224, and the other end of the spring 221 abuts against the spring pressure plate 223. The fixing mechanism 2 also includes a baffle assembly 23, and the baffle assembly 23 includes a circular shaft 231 and a baffle 232. The circular shaft 231 is arranged on the cabinet body 1, and the baffle 232 is rotatably connected to the circular shaft 231.
[0030] With such arrangement, the user can use the locking assembly 21 provided on the cabinet shell 1 to open the cabinet body 5 through the drawer cabinet 4. When the cabinet body 5 needs to be locked, the second cylinder 213 will extend and retract, driving the limit block 214 on the output shaft of the second cylinder 213 in the slide groove 212 on the cabinet shell 1 to abut against the limit hole 215 on the slide rail 211, thereby locking the cabinet body 5. At the same time, when opening and closing the drawer cabinet 4 and the cabinet body 5, through the rebound assembly 22, the cabinet body 5 first contacts the rebound pad 224 to buffer the rebound force of the cabinet body 5 when closing, and at the same time, the operator pushes the drawer cabinet 4 to retract through the handle 7, and the spring 221 is rebounded. The pressure retraction of the pad 224 drives the first cylinder 222 to retract. The first cylinder 222 can quickly respond to the control signal to achieve rapid telescopic movement, while the spring 221 can provide stable rebound force. Combining the two, fast and precise position control can be achieved. At the same time, the spring 221 can absorb and buffer the impact force during the movement, reduce the vibration and wear of the mechanical structure, and extend the life of the equipment. Finally, after the drawer cabinet 4 is completely closed, the user uses the baffle assembly 23 to rotate the baffle 232, driving the circular shaft 231 with the circular shaft 231 as the center of the circle to close the drawer cabinet 4, thereby reducing the probability of the drawer cabinet 4 automatically opening and causing danger.
[0031] The implementation principle of the contact box of a drawer cabinet in the embodiment of the present application is as follows: the status of the contact box 8 is observed through the operation panel, and the status of the electrical system is intuitively monitored and controlled. When the user needs to repair the drawer-type contact box 8, the operating handle 9 is used to manually operate the switch or circuit breaker in the contact box 8, so as to quickly cut off the power supply or perform other operations in an emergency. The user uses the baffle assembly 23 on the drawer cabinet 4 to rotate the baffle 232, driving the circular shaft 231 with the circular shaft 231 as the center of the circle to open the drawer cabinet 4, and at the same time pull out the drawer cabinet 4 and the cabinet body 5 through the handle 7. When the user repairs the contact box of the drawer cabinet, the user can use the locking assembly 21 set on the cabinet shell 1 to open the cabinet body 5 through the drawer cabinet 4. When the cabinet body 5 needs to be locked, the second cylinder 213 is extended and retracted, driving the limit block 214 on the output shaft of the second cylinder 213 in the slide groove 212 on the cabinet shell 1 to abut against the limit hole 215 on the slide rail 211, thereby locking Dead cabinet 5. At the same time, when opening and closing the drawer cabinet 4 and the cabinet 5, the contact box 8 on the cabinet 5 is inspected, and the wires in the drawer cabinet 4 are inspected and repaired through the horizontal busbar, vertical busbar and wiring hole 63. When closing the drawer cabinet 4, through the rebound component 22, the cabinet 5 first contacts the rebound pad 224 to buffer the rebound force of the cabinet 5 when closing. At the same time, the operator pushes the drawer cabinet 4 to retract through the handle 7. The spring 221 receives the pressure of the rebound pad 224 and retracts, driving the first cylinder 222 to retract. The first cylinder 222 can respond quickly to the control signal to achieve rapid telescopic action, while the spring 221 can provide stable rebound force. Combining the two, fast and precise position control can be achieved. At the same time, the spring 221 can absorb and buffer the impact force during the movement. Finally, after the drawer cabinet 4 is completely closed, the user uses the baffle assembly 23 to rotate the baffle 232 to drive the circular shaft 231 with the circular shaft 231 as the center to close the drawer cabinet 4.
[0032] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
