[0002] At present, sliding doors and folding door and window systems have become more and more popular among users. Good ventilation and light transmission effects make sliding doors and folding door and window systems the first choice for more decorators. Since most of the doors or windows of sliding doors and folding door and window systems are equipped with hanging wheels to achieve sliding, when the doors or windows are in the closed state, in order to prevent the doors or windows from sliding freely, they are generally equipped with locking devices to lock the closed doors or windows.

[0003] As attached Figure 7 The existing locking device shown in the figure comprises a fixed seat mounted on a fixed leaf or a fixed frame and a movable seat mounted on a movable door leaf. A ball bearing is arranged on the movable seat. When the door is closed, the ball bearing contacts / drives the locking block of the locking mechanism. The locking mechanism is displaced under the action of the elastic member, so that the locking mechanism locks or unlocks the ball bearing, so that the door leaf or window leaf can stop at a desired position when the door is closed. However, the structure currently has the following disadvantages:

[0004] 1. When used for heavier sliding doors, the closing force of the sliding door under the action of inertia is too large, which directly damages the locking device;

[0005] 2. Since most parts are made of metal, the friction between the metals at the moment of contact causes noise, affecting the user's experience. Utility Model Content

[0026] like Figures 1 to 6The anti-collision structure of a sliding door locking device shown in the figure comprises a fixed seat 10 and a movable seat 20 which moves linearly forward and backward relative to the fixed seat 10;

[0027] Specifically, an anti-collision member 30 is provided at the rear end of the fixing seat 10, and the anti-collision member 30 is made of plastic. A snap-fit ​​structure is provided on the front side of the anti-collision member 30, and the snap-fit ​​structure includes a left elastic fastener 310 and a right elastic fastener 320, and a buffer cavity 301 and a locking cavity 302 are formed between the left elastic fastener 310 and the right elastic fastener 320; to be precise, a buffer surface is provided on the inner side of the front end of the left elastic fastener 310 and the right elastic fastener 320, and the buffer surface is inclined, and the end surface faces forward, so that the two buffer surfaces form a buffer cavity 301, and a locking surface is provided on the inner side of the rear end of the left elastic fastener 310 and the right elastic fastener 320, and the locking surface is inclined, and the end surface faces rearward and front, so that the two locking surfaces form a locking cavity 302. It should be understood that a protrusion is formed between the buffer surface and the locking surface.

[0028] Specifically, a buckle 210 is provided on the movable seat 20, and the buckle 210 is a vertically arranged cylindrical pin body, and the middle part of the buckle 210 is fixedly connected to the movable seat 20, and two groups of buckle structures are provided, and are respectively provided at the upper and lower ends of the front side of the anti-collision member 30; to be precise, a locking auxiliary member 330 is provided between the two groups of buckle structures, and when the buckle 210 enters the locking cavity 302, it abuts against the locking auxiliary member 330;

[0029] It should be understood that when the door is closed, the movable seat 20 moves linearly toward the fixed seat 10, and the latch 210 contacts the anti-collision member 30 and slides through the buffer cavity 301 into the locking cavity 302. When sliding through the buffer cavity 301, the inclined surface of the locking surface provides the latch 210 with an elastic buffering force. When the latch 210 enters the raised portion, the elastic clamping force between the left elastic latch 310 and the right elastic latch 320 provides a portion of buffering for the latch 210. After the latch 210 enters the locking cavity 302, the left elastic latch 310 and the right elastic latch 320 elastically reset. A locking auxiliary member 330 is provided between the two groups of latch structures. When the latch 210 enters the locking cavity 302, the locking auxiliary member 330 cooperates with the inclined surface of the locking surface to achieve elastic locking of the latch 210, so that the movable seat 20 is locked relative to the fixed seat 10.

[0030] In this embodiment, an ejection mechanism 40 is also included. The ejection mechanism 40 includes an ejection member 410 and an elastic member 420. The ejection member 410 is movably arranged on the fixed seat 10. One end of the elastic member 420 abuts against the ejection member 410, and the other end abuts against the fixed seat 10. The movable seat 20 is provided with an actuating member 220. When the buckle 210 enters the locking cavity 302, the actuating member 220 abuts against the ejection member 410, so that the elastic member 420 provides elastic force for the actuating member 220. Use force. It needs to be understood that the actuator 220 abuts against the ejector 410 when the movable seat 20 is in the locked state. When closing the door, the ejector 410 is pressed by the actuator 220 to compress the elastic member 420 to store energy. During the door opening process, after the latch 210 leaves the locking cavity 302, the elastic member 420 releases the stored energy to drive the ejector 410 to move in a straight line. The ejector 410 drives the actuator 220 to move, so that the movable seat 20 automatically moves relative to the fixed seat 10, thereby realizing the automatic door opening function.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
