[0006] Preferably, the adjustable structure includes a slide groove, the vertical frame is provided with a slide groove, the vertical frame is provided with a limit port, the vertical frame is provided with a slider, the slider is provided with a threaded sleeve, a push rod is connected to the slider, a limit rod is provided on the push rod, a spring is fixed in the push rod, and a nut is connected to the threaded sleeve.

[0007] Preferably, the crossbar is provided with connecting interfaces.

[0008] Preferably, a positioning sleeve is fixed in the slider, the positioning sleeve is located at the rear end of the push rod, and the push rod is slidably connected to the positioning sleeve.

[0009] Preferably, the slider has a movable groove inside, and the limiting rod is located inside the movable groove.

[0010] Preferably, after the nut is threadedly connected to the threaded sleeve, the nut will press against the surface of the vertical frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: When the position of the mounting plate in the cabinet needs to be adjusted, the mating block is inserted into the corresponding mating interface to adjust the position of the mounting plate in the cabinet. This allows for convenient installation. When the position of the mounting plate needs to be adjusted vertically, the push rod is pressed to push the limit rod to slide in the movable groove. Then the limit rod will slide out of the limit opening, releasing the limit on the slider. The slider can then be slid to slide in the vertical frame to adjust the position of the mounting plate. After adjustment, the push rod is released, and under the action of the spring, the limit rod will move into the corresponding limit opening, completing the limit. This achieves the beneficial effect of conveniently adjusting the position of the mounting bracket without disassembly and readjustment. Attached Figure Description

Detailed Implementation

[0014] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0015] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a low-voltage incoming line cabinet for power distribution systems, including a cabinet body 1. The cabinet body 1 is used to protect components such as vacuum circuit breakers and disconnect switches. A panel 2 is provided on the cabinet body 1. The panel 2 can display whether the equipment is energized to ensure safe operation. A cabinet door 3 is provided at the front end of the cabinet body 1. An adjustable mounting bracket 4 is provided in the cabinet body 1. The main function of the incoming line cabinet is to introduce external power into the system and distribute electrical energy to the next level of power distribution system.

[0016] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides a low-voltage incoming line cabinet for power distribution system. The adjustable mounting frame 4 includes a crossbeam 41. The crossbeam 41 is fixed at both the left and right ends inside the cabinet body 1. The crossbeam 41 is provided with a pair of interfaces 42, thus realizing the setting of multiple pairs of interfaces 42.

[0017] The cabinet 1 has a vertical frame 43 inside, and a docking block 44 is provided on the vertical frame 43. The docking block 44 is inserted into the docking interface 42 to fix the vertical frame 43 to the horizontal frame 41.

[0018] A mounting plate 45 is provided on the vertical frame 43, which is used to install components such as vacuum circuit breakers.

[0019] An adjustable structure 46 is provided on the mounting plate 45. The adjustable structure 46 includes a slide groove 461. The slide groove 461 is opened on the front side of the vertical frame 43. A limit opening 462 is opened on the side of the vertical frame 43. A slider 463 is integrally formed at the end of the mounting plate 45. The slider 463 is located in the vertical frame 43. A threaded sleeve 464 is fixed at the front end of the slider 463. A push rod 465 is slidably connected in the slider 463. A limit rod 466 is provided on the push rod 465. A spring 467 is fixed in the push rod 465. A nut 468 is connected to the threaded sleeve 464.

[0020] A positioning sleeve 469 is fixed in the slider 463. The positioning sleeve 469 is located at the rear end of the push rod 465, and the push rod 465 is slidably connected to the positioning sleeve 469 to position the push rod 465 and prevent the push rod 465 from tilting.

[0021] The slider 463 has a movable groove 4610 inside, and the limiting rod 466 is located inside the movable groove 4610, which can effectively suppress the deformation of the limiting rod 466.

[0022] When the nut 468 is threadedly connected to the threaded sleeve 464, the nut 468 will press against the surface of the vertical frame 43 to fix the slider 463 and prevent the slider 463 from moving backward.

[0023] Specifically, when it is necessary to adjust the front-to-back position of the mounting plate 45 in the cabinet 1, the mating block 44 is inserted into the corresponding mating interface 42, thereby enabling the front-to-back adjustment of the mounting plate 45 in the cabinet 1. This is also convenient for installation. When it is necessary to adjust the vertical position of the mounting plate 45, the push rod 465 is pressed to push the limit rod 466 to slide in the movable groove 4610. Then the limit rod 466 will slide out of the limit opening 462, releasing the limit on the slider 463. Then the slider 463 can be slid to slide in the vertical frame 43 to adjust the position of the mounting plate 45. After adjustment, the push rod 465 is released. Under the action of the spring 467, the limit rod 466 will move into the corresponding limit opening 462, thus completing the limit. This achieves the beneficial effect of conveniently adjusting the position of the mounting frame without disassembly and readjustment.
