DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Please refer to Figs. 1-3 The present application provides a technical solution: a power distribution cabinet door structure with a fixed-angle locking function, comprising a cabinet body 1 with an open front end and a cabinet door 2 rotatably installed at the front end of the cabinet body 1 through a door shaft 3. A wheel groove 201 is formed in the middle of the left end of the cabinet door 2. A lock cylinder 4 is fixedly connected to the inner side of the wheel groove 201 at the middle of the door shaft 3. A slide lock mechanism is arranged between the cabinet door 2 and the lock cylinder 4 to prevent accidental closing of the fixed-angle lock after the cabinet door 2 is opened.

[0027] Specifically, as shown in Figs. 1-3 The slide lock mechanism includes a horizontal sliding rail 204 fixed to the rear end of the cabinet door 2 and close to one side of the lock cylinder 4, a horizontal sliding block 5 movably installed on the inner side of the horizontal sliding rail 204 and having its left end penetrating the lock cylinder 4, and a plurality of lock grooves 401 arranged in a ring array on the lock cylinder 4 and used to accommodate the left end of the horizontal sliding block 5. When the horizontal sliding block 5 is horizontally slid into the lock groove 401 on the lock cylinder 4, the cabinet door 2 can be restricted from rotating on the door shaft 3 because the lock cylinder 4 is fixed to the door shaft 3.

[0028] The middle of the horizontal sliding block 5 is fixedly connected to a handle 501 penetrating the cabinet door 2 forward. A horizontal sliding groove 202 is formed on the cabinet door 2 outside the handle 501. The handle 501 can be directionally and distance-adjustably slid in the horizontal sliding groove 202, thereby limiting the sliding guide of the horizontal sliding block 5 on the horizontal sliding rail 204 and preventing the horizontal sliding block 5 from excessively sliding into the lock groove 401 of the lock cylinder 4 or excessively sliding out of the horizontal sliding rail 204.

[0029] Specifically, as shown in Figs. 1-3As shown, the horizontal sliding block 5 and the cabinet door 2 are provided with a limiting part for limiting the horizontal sliding adjustment of the horizontal sliding block 5, the limiting part comprises a limiting column 502 vertically movably installed at the right end of the horizontal sliding block 5 and penetrating through the cabinet door 2 forwardly, a handle 503 installed at the rear end of the limiting column 502, and two limiting holes 203 horizontally and distantly distributed on the cabinet door 2, when the horizontal sliding block 5 is completely slid into the lock groove 401 of the lock cylinder 4, the handle 501 is at the leftmost position in the horizontal sliding groove 202 at this time, and the limiting column 502 can be slid forwardly into the left limiting hole 203 to limit the horizontal sliding of the horizontal sliding block 5, when the handle 501 is at the rightmost position in the horizontal sliding groove 202, the horizontal sliding block 5 is completely slid away from the lock groove 401 of the lock cylinder 4, and the limiting column 502 can be slid forwardly into the right limiting hole 203 to limit the horizontal sliding of the horizontal sliding block 5.

[0030] Specifically, as shown in the figure, Figs. 1-3 The upper end of the door shaft 3 is integrally fixedly connected with an anti-deviation block 301, and the upper end of the cabinet body 1 is provided with an anti-deviation groove 101 for accommodating the anti-deviation block 301, the anti-deviation block 301 and the anti-deviation groove 101 can lock the door shaft 3 against deviation on the cabinet body 1, prevent the door shaft 3 and the lock cylinder 4 from being deviated under force, and thus improve the stability of the overall operation of the slide lock mechanism.

[0031] Working principle: when the cabinet door 2 needs to be locked at a certain angle in front of the cabinet body 1, the operator can pre-adjust the cabinet door 2 to rotate on the cabinet body 1 through the door shaft 3, when the cabinet door 2 is adjusted to a suitable angle, the operator can hold and slide the handle 501 on the inside of the cabinet door 2 or the outside of the cabinet door 2, and slide the horizontal sliding block 5 on the horizontal sliding rail 204, when the horizontal sliding block 5 moves towards the lock cylinder 4 and is inserted into the lock groove 401 at the corresponding position, the cabinet door 2 is locked and fixed between the door shaft 3 and the cabinet body 1 at this time, in order to prevent the horizontal sliding block 5 from being deviated, the operator can hold the handle 503 and slide the limiting column 502 forwardly into the limiting hole 203 at the corresponding position on the cabinet door 2, so as to limit and fix the horizontal sliding block 5 between the horizontal sliding rail 204 and the cabinet door 2.

[0032] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
