[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 Fig.10 and attached Fig.11 The existing locking device shown includes a fixed seat installed on a fixed leaf or a fixed frame and a movable seat installed 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 the desired position when the door is closed. However, the current structure has a disadvantage that during the assembly process, the ball bearing needs to be installed on the movable seat through a rotary riveting machine to allow rivets and the ball bearing to be installed, resulting in low production efficiency and high cost.

[0035] like Figures 1 to 9 A sliding door pulley locking device shown includes a fixed seat 10, a movable seat 20 and a locking mechanism 30;

[0036] Specifically, a movable groove 101 is provided on the fixed seat 10, a first sliding groove 102 is provided below the movable groove 101, and a through groove 103 is provided between the movable groove 101 and the first sliding groove 102, the through groove 103 passes through the movable groove 101 and the first sliding groove 102, a second sliding groove 104 is provided on the right side of the movable groove 101, a guide groove 105 is provided between the second sliding groove 104 and the movable groove 101, and the guide groove 105 passes through the movable groove 101 and the second sliding groove 104;

[0037] Specifically, an actuating member 210 is disposed on the movable seat 20, and the actuating member 210 and the movable seat 20 are an integral structure. The actuating member 210 moves forward and backward in the movable groove 101, and a toggle portion 211 is disposed at the bottom end of the actuating member 210, and an actuating portion 212 is disposed at the front end, wherein the toggle portion 211 is in an inverted "△" shape;

[0038] The locking mechanism 30 includes a locking block 310 and a first elastic member 320. The locking block 310 moves linearly up and down in the first sliding groove 102. An anti-slip portion 311 is provided at the upper end of the locking block 310. The anti-slip portion 311 passes through the through groove 103 and extends to the movable groove 101. The anti-slip portion 311 is in a "△" shape, and the inclined surface of the anti-slip portion 311 is adapted to the inclined surface of the toggle portion 211, so that the toggle portion 211 drives the locking block 310 to move linearly when contacting the anti-slip portion 311. A slot 312 is provided at the bottom center of the locking block 310. One end of the first elastic member 320 is inserted into the slot 312 to provide elasticity for the locking block 310. Force; It should be understood that when closing the door, the movable seat 20 installed on the movable door or window sash moves toward the fixed seat 10 until the actuator 210 of the movable seat 20 enters the movable groove 101, and the inverted "△"-shaped toggle portion 211 on the actuator 210 drives the lock block 310 to move in a straight line when contacting the anti-slip portion 311. When the actuator 210 passes through the lock block 310 and enters the locking area, the lock block 310 loses the downward pressure and is reset by the elastic force of the first elastic member 320. The actuator 210 cannot pass through the lock block 310 without external force, so that the door or window sash can achieve the restriction and positioning function when it runs to the closed position.

[0039] Specifically, the lower end of the toggle portion 211 and the upper end of the anti-slip portion 311 are chamfered, so that when the actuator 210 contacts and pushes the locking block 310 to the bottom, the friction between the two is reduced to prevent noise.

[0040] Specifically, the present embodiment further includes an ejection mechanism 40, which includes an ejection member 410 and a second elastic member 420. The ejection member 410 is slidably disposed in the second sliding groove 104 along the front-rear linear direction, and the ejection member 410 is provided with a top block 411 extending toward the movable groove 101, and the top block 411 extends to the movable groove 101 through the guide groove 105. The rear end of the actuator 210 is provided with an actuating portion 212, and the actuator 210 abuts against the top block 411 when the locking mechanism 30 is locked. The second elastic member 420 is One end is in contact with the ejector 410, and the other end is in contact with the fixed seat 10; when closing the door, the ejector 410 is pressed by the actuator 210 to compress the second elastic member 420 to store energy. During the door opening process, the door leaf or window leaf is driven by external force, so that the actuator 210 passes through the locking block 310 from the locking area, and the second elastic member 420 releases the stored energy to drive the ejector 410. The ejector 410 pushes the actuator 210 to move through the top block 411, so that the movable seat 20 and the door leaf or window leaf move automatically, thereby realizing the automatic door opening function.

[0041] In addition, the second elastic member 420 is a compression spring, the rear end of the second sliding groove 104 is provided with a first positioning column 106, the ejection member 410 is provided with a spring mounting groove 412, the end of the spring mounting groove 412 is provided with a second positioning column 413, and the two ends of the second elastic member 420 are respectively sleeved on the first positioning column 106 and the second positioning column 413. This structure not only facilitates the installation of the second elastic member 420, but also prevents the second elastic member 420 from deviating and causing the ejection mechanism 40 to fail.

[0042] 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.
