[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, a power distribution cabinet for conveniently locking a circuit breaker trolley comprises a cabinet body 1, a pair of slide rails 2 and a limiting mechanism 3.

[0027] A pair of slide rails 2 are horizontally and symmetrically arranged in the cabinet 1 .

[0028] like Figure 1 and Figure 2 As shown, the limiting mechanism 3 is arranged on the inner side of any one of the slide rails.

[0029] The limiting mechanism 3 includes a mounting seat 4, a rotating shaft 5 and a limiting member. The mounting seat 4 is detachably fixed in the cabinet 1; the rotating shaft 5 is horizontally rotatably arranged on the mounting seat 4, and the rotating shaft 5 is parallel to the slide rail 2.

[0030] The limiting member includes a connecting seat 6 and a limiting strip 7; the connecting seat 6 is fixed on the rotating shaft 5; the limiting strip 7 is fixed to the bottom of the connecting seat 6 and points to the slide rail; an avoidance hole 8 is provided on the slide rail on the same side as the limiting mechanism 3 at a position opposite to the limiting strip 7.

[0031] In this embodiment, if Figure 3 As shown, the connecting seat 6 is sleeved on the rotating shaft 5, and a through hole 9 is provided on the top of the connecting seat 6, and a connecting hole 10 is provided on the rotating shaft 5 at a position opposite to the through hole 9, and a pin (not shown in the figure) is inserted into the through hole 9, and the pin passes through the through hole 9 and extends into the connecting hole 10 of the rotating shaft 5; such an arrangement realizes a detachable fixation between the connecting seat 6 and the rotating shaft 5, which is convenient for disassembly and maintenance.

[0032] In this embodiment, if Figure 3 As shown, in order to facilitate the rotation of the rotating shaft 5, a handle 11 is fixed to the outer end of the rotating shaft 5.

[0033] In this embodiment, in order to improve the stability of the connecting seat 6, as shown in FIG. Figure 4 As shown, a reinforcing shaft 12 is fixed to the lower portion of the connecting seat 6 .

[0034] When the trolley circuit breaker in the power distribution cabinet needs to be taken out, the handle 11 is pulled to rotate the shaft 5, the connection seat 6 rotates accordingly, the limit bar 7 retracts backward from the avoidance hole 8 on the slide rail 2, and the trolley circuit breaker can slide out along the slide rail 2. When the trolley circuit breaker needs to be placed in the power distribution cabinet, it is slid into the power distribution cabinet along the slide rail 2, and the handle 11 is used to rotate the shaft 5, and finally the limit bar 7 extends out of the avoidance hole 8 on the slide rail 2 to block the manual circuit breaker and limit it.

[0035] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all within the scope defined by the claims of this application.
