[0048] In one embodiment of the present invention, the locking structure 700 includes:

[0049] A clamping block 710 engaged with the limiting slide groove 311, wherein the clamping block 710 is slidably connected to the hinge seat 500, the hinge seat 500 is provided with a slide groove, and the upper end of the clamping block 710 is slidably inserted into the slide groove; a first inclined surface is provided on one side of the clamping block 710;

[0050] A return spring 730 for pushing the clamping block 710 to return to its original position, wherein the return spring 730 is disposed between the clamping block 710 and the hinge seat 500;

[0051] Specifically, a slide groove is provided inside the articulated seat 500, and the upper end portion of the clamping block 710 is inserted into the slide groove to achieve a sliding connection with the articulated seat 500. A first inclined surface is designed on one side of the clamping block 710, and the inclined surface cooperates with the upper end of the first door body 310, so as to achieve a sliding displacement of the clamping block 710 through the interaction between the inclined surface and the inner wall when the clamping block 710 is subjected to an external force that contacts the upper end of the first door body 310. In addition, a reset spring 730 is provided between the clamping block 710 and the articulated seat 500. When the external force is removed, the elastic force of the reset spring 730 causes the clamping block 710 to automatically return to its original position, thereby achieving a clamping effect;

[0052] In one embodiment of the present utility model, a second inclined surface 315 is provided at one end of the limiting slider 313, and the second inclined surface 315 abuts against the clamping block 710;

[0053] A buffer spring 322 is installed on the inner wall of the second door body 320. The buffer spring 322 is arranged corresponding to the side wall of the first door body 310. A limit block 323 for limiting the deformation of the buffer spring 322 is slidably connected to the inner wall of the second door body 320.

[0054] Specifically, a limiting slider 313 for connecting with the second door body 320 is provided at one end of the first door body 310, and a second inclined surface 315 is provided at one end of the slider, and the second inclined surface 315 conflicts with the block 710, and is used to unlock the first door body 310 when the second door body 320 is opened to the maximum extent, so that the first door body 310 can rotate around the hinge seat 500. Buffer springs 322 are installed on the inner wall of the second door body 320, and these buffer springs 322 are arranged corresponding to the side walls of the first door body 310, and are used to absorb the impact force of the collision between the second door body 320 and the first door body 310 when the second door body 320 is opened. The inner wall of the second door body 320 is also slidably connected to a limit block 323 for limiting the deformation of the buffer spring sheet 322, ensuring the buffering effect while preventing excessive deformation, and also for limiting the second door body 320 from driving the second inclined surface 315 to conflict with the block 710. When the first door body 310 needs to be opened, the limit block 323 is pushed downward so that the limit block 323 leaves the buffer spring sheet 322, increasing the deformation of the buffer spring sheet 322, causing the second inclined surface 315 to conflict with the block 710, thereby unlocking the first door body 310.

[0055] In one embodiment of the present utility model, the limiting slide groove 311 is a track-changing slide, and the track-changing slide includes a first slide and a second slide, the first slide is arranged in parallel with the second slide, the first slide is away from the inner surface of the first door body 310 relative to the second slide, and the first slide and the second slide are smoothly connected;

[0056] Specifically, the track change slide is designed for automatic track change of the second door body 320, and can realize rapid conversion between different tracks during the opening and closing process of the second door body 320. The device is mainly composed of a first slide and a second slide, which are arranged in parallel to provide a basis for the track change of the second door body 320. The first slide and the second slide are designed to have a smooth transition at the joint to ensure a smooth transition of the rail vehicle during the track change process, reduce friction and resistance, and improve the efficiency and safety of track change;

[0057] Since the first slide is away from the inner surface of the first door body 310, when the second door body 320 is pushed to open, the limiting slider 313 slides from the second slide into the first slide, driving the side of the second door body 320 that is in contact with the sealing gasket 110 to separate from the sealing gasket 110, thereby reducing the friction during the opening process and extending the service life of the sealing gasket 110.

[0058] The above-mentioned embodiments only express several implementation methods of the utility model. The descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent.

[0059] It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model, and these are all within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
