DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below with reference to specific diagrams. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0026] See also Figure 1-Figure 6 The embodiment of the present invention provides a technical solution: a power distribution cabinet for facilitating wiring, comprising a cabinet body 1, a cover plate 3 which can be turned over is rotatably connected to the top of the cabinet body 1, a mounting plate 4 for installing electrical components is movably arranged in the cabinet body 1, and the mounting plate 4 divides the internal space of the cabinet body 1 into a wiring cavity 5 and an electrical component installation cavity 6;

[0027] The first slide grooves 11 are provided on the two side walls inside the cabinet 1 in the vertical direction, and the two first slide grooves 11 are both slidably connected with the sliding seats 43, and the mounting plate 4 is rotatably connected between the two sliding seats 43 through an axis, and the side wall of the mounting plate 4 is integrally formed with a strip positioning block 44 above the sliding seat 43;

[0028] A plurality of strip-shaped wire holes 41 are formed through the mounting plate 4, a wiring guide 42 used in conjunction with the strip-shaped wire holes 41 is formed on the back of the mounting plate 4, a wire outlet hole 421 is formed on the outer wall of the wiring guide 42, a wire fixing component 422 is formed in the wiring guide 42, the cabinet door 2 is rotatably connected to the opening on the front surface of the cabinet body 1 through a hinge, the wiring guide 42 is an S-shaped structure, and the cross section of the wiring guide 42 is a concave structure.

[0029] Specifically, in the power distribution cabinet which is convenient for wiring, a mounting plate 4 is provided in the cabinet body 1 for installing electrical components. The mounting plate 4 divides the cabinet body 1 into two chambers, namely, a wiring chamber 5 and an electrical component installation chamber 6. The wire is fixed in the wiring guide rail 42 on the back side of the mounting plate 4 and fixed by the wire fixing assembly 422. The end of the wire is introduced into the front surface of the mounting plate 4 through the wire outlet hole 421 and the strip-shaped wire threading hole 41, and connected with the electrical component fixed on the front surface of the mounting plate 4. Such a structural design makes the wiring located on the back side of the mounting plate 4, namely, located in the wiring chamber 5, and the electrical component is installed on the front surface of the mounting plate 4, namely, located in the electrical component installation chamber 6, so that the wire and the electrical component do not need to be laid on the same board, which is convenient for combing and improving its neatness. In actual wiring, the cover plate 3 can be flipped open, the mounting plate 4 can be pulled upward, and the sliding seat 43 can be driven to move upward in the first slide groove 11, so that the mounting plate 4 moves up to the top of the cabinet body 1. At this time, the mounting plate 4 is rotated so that the mounting plate 4 rotates to a horizontal state (as shown in the attached figure). Figure 3 ), so that the entire mounting plate 4 is located outside the cabinet 1. At this time, the wiring will not be affected by the internal space of the cabinet 1. The wires are introduced into the cabinet 1 from the back plate of the cabinet 1, and then the wiring is carried out through the wiring guide rails 42 arranged on the mounting plate 4. When the wiring is completed, the mounting plate 4 is flipped in a state, and the sliding seat 43 is pushed down to the bottom end of the first slide groove 11. At this time, the strip positioning block 44 arranged on the mounting plate 4 is stuck in the first slide groove 11, and the mounting plate 4 is limited, so that the mounting plate 4 cannot rotate.

[0030] In another embodiment provided by the present invention, the wire fixing component 422 includes two second slide grooves 423, and the two second slide grooves 423 are symmetrically arranged on the inner walls on both sides of the S-shaped wiring guide 42. Slide blocks 424 are slidably connected in the two second slide grooves 423. A threaded rod 425 is threadedly connected to the upper surface of the wiring guide 42. The bottom end of the threaded rod 425 extends into the second slide groove 423 and is rotatably connected to the slide block 424. A fixing block 426 is fixed on the slide block 424. A fixing plate 429 is rotatably connected to the fixing block 426 through a connecting shaft 427. A torsion spring 428 is sleeved on the connecting shaft 427. A cavity 430 is arranged in the slide block 424. A winding roller 431 is rotatably connected in the cavity 430. A connecting rope 433 is wound around the winding roller 431. 1 is fixedly connected with a gear plate 432, and a rack 435 is embedded on the inner wall of the second slide groove 423. The rack 435 is meshed with the gear plate 432. When the slider 424 moves up and down in the second slide groove 423, the gear plate 432 walks on the rack 435, automatically driving the winding roller 431 to rotate to realize the retraction and release of the connecting rope 433. The other end of the connecting rope 433 is connected to the arc frame 434 welded on the inner wall of the fixed plate 429. The fixed plate 429 is an arc structure. There are two fixed plates 429, and the opposite sides of the two fixed plates 429 are in contact with each other. The two ends of the torsion spring 428 are respectively fixed to the fixed block 426 and the fixed plate 429. There are two torsion springs 428, and the two torsion springs 428 are symmetrical with respect to the fixed plate 429.

[0031] Specifically, on the basis of the above embodiment, when it is necessary to lay the line in the wiring guide 42, firstly, the slider 424 is driven to move up in the second slide groove 423 by rotating the threaded rod 425. When the slider 424 moves up, the fixed block 426 and the fixed plate 429 are synchronously driven to move up, and the gear plate 432 rotates under the drive of the rack 435. The gear plate 432 drives the winding roller 431 to rotate and releases the connecting rope 433, thereby driving the fixing plate 429 to flip open through the connecting shaft 427 under the elastic force of the torsion spring 428. At this time, the wire is placed in the wiring guide 42, below the two fixing plates 429, and then reversed. Rotate the threaded rod 425, and the threaded rod 425 drives the slider 424 to move downward in the second slide groove 423. When the slider 424 moves downward, the gear plate 432 rotates driven by the rack 435. At this time, the gear plate 432 drives the winding roller 431 to rotate in the opposite direction to reel in the connecting rope 433. The connecting rope 433 pulls the fixing plate 429 to rotate, so that the two fixing plates 429 are closed to each other, and the wires located in the wiring guide rail 42 are limited and fixed. The setting of such a wire fixing component 422 realizes the automatic fixation of the wires, and the fixing and untying of the wires are very convenient, which improves the wiring efficiency and can be reused.
