[0031] A rotating mechanism 1, which is arranged on the door panel and rotates on the door panel; a locking mechanism 2, which is arranged on the door frame and has a limiting groove 25 on one side thereof, in which the rotating mechanism 1 is limited and locked, and the rotating mechanism 1 cooperates with the locking mechanism 2 to lock the door panel and the door frame when they are closed;

[0032] The limiting groove 25 is open on one side, and the opening of the limiting groove 25 is close to the rotating mechanism 1 so as to cooperate with the rotating mechanism 1;

[0033] The rotating mechanism 1 is provided with a locking tongue 13 of a fan-shaped structure, and the locking tongue 13 is clamped in the limiting groove 25 to limit and fix the door panel and the door frame as a whole. The locking tongue 13 of the fan-shaped structure can make the locking tongue 13 enter the limiting groove 25 more smoothly;

[0034] Specifically, one side surface of the locking tongue 13 is inclined, so that the locking tongue 13 can continuously tighten and lock the rotating mechanism 1 after entering the limiting groove 25 .

[0035] In this embodiment, when the lock tongue 13 slides into the limiting groove 25, the lock tongue 13 is always in contact with the limiting groove 25 under the action of the inclined surface of the lock tongue 13, so that the rotating mechanism 1 drives the door panel to gradually move horizontally along the hinge with the door frame, so that the door panel and the door frame are completely closed. This effectively solves the problem of the door panel and the door frame having a door gap when closed in the prior art; on the other hand, when the lock tongue 13 rotates into the limiting groove 25, the thickness of the lock tongue 13 gradually increases, so that after the lock tongue 13 slides into the locking mechanism 2, it can ensure that the door panel and the door frame are in a locked state.

[0036] In some embodiments, the rotating mechanism 1 further includes: a mounting base 11, and a rotating block 12 disposed on the mounting base 11;

The staff can rotate the rotating block 12 by the handle, and the handle 121 can be quickly installed or removed by bolt connection.

[0039] In some embodiments, the locking mechanism 2 includes a fixed plate 21, a locking block 22 and a square block 23; the fixed plate 21 is arranged on the door frame close to the rotating mechanism 1, and is used to install the locking mechanism 2, the locking block 22 is arranged on the outer side of the fixed plate 21, and is used to cooperate with the locking tongue 13 to fix and lock the rotating mechanism 1, so that the door panel is fixed and locked, the limiting groove 25 is opened in the locking block 22, the square block 23 is an elastic block, and the square block 23 is arranged on the inner wall of the limiting groove 25, the square block 23 can make the locking tongue 13 further limited and fixed under the action of elastic force, and it is a detachable structure, which is convenient for the staff to replace and maintain.

[0040] Preferably, the locking mechanism is further provided with a limiting assembly 24, the limiting assembly 24 comprising a mounting frame 241 provided on the locking block 22, a pin 242 provided in the mounting frame 241 and used to cooperate with the locking tongue 13, a clamping plate 243 provided on the pin 242 and limiting the position of the pin, and a spring 244 for returning the pin 242 to its original position.

[0041] The mounting frame 241 is arranged on the outer side of the locking block 22, the ejector pin 242 is arranged to slide through the mounting frame 241, the locking block 22 and the square block 23, one end of the spring 244 is connected to one side of the clamping plate 243, and the other end is connected to the mounting frame 241, the clamping plate 243 is sleeved on the ejector pin 242 and the other side of the clamping plate 243 is in contact with the locking block 22, so that the ejector pin 242 can always maintain the initial position when it is not in contact with the locking tongue 13;

[0042] The ejector pin 242 can further lock the lock tongue 13. The clamping plate 243 is fixedly sleeved on the outer side of the ejector pin 242 to limit the position of the ejector pin 242. The spring 244 is fixedly assembled between the locking block 22 and the mounting bracket 241. The staff can manually release the lock tongue 13 to make it rotate by pulling the ejector pin 242.

[0046] The slide groove 131 cooperates with the ejector pin 242. When the ejector pin 242 contacts the slide groove 131, the slide groove 131 presses against the ejector pin 242. At this time, the spring 244 contracts, so that the ejector pin 242 abuts against the slide groove 131 by the restoring force of the spring 244 to lock the lock tongue 13.

[0047] More preferably, a plug hole 132 is provided in the slide groove 131 , wherein the size of the plug hole 132 matches the thickness of the ejector pin 242 .

[0048] In this embodiment, as the slide groove 131 moves, the ejector pin 242 slides into the insertion hole 132 along the path of the slide groove 131, and the spring 244 contracts to form a certain resilience. When the lock tongue 13 is locked, the spring 244 is reset to allow the ejector pin 242 to be inserted into the insertion hole 132 to lock the lock tongue 13, thereby preventing the lock tongue 13 from rotating.

[0049] The beneficial effect is that, on the one hand, the lock tongue 13 is further locked, and on the other hand, the lock tongue 13 can be prevented from rotating, thereby preventing a gap from being generated between the door panel and the door frame.
