DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0025] like Figures 1 to 8As shown, a sliding door lock includes a door lock body 101, and two side walls opposite to each other at the front and rear of the door lock body 101 are respectively installed with plate connecting members 102, and a side wall of the plate connecting member 102 is provided with a lock head 105, and the end of the lock head 105 close to the door lock body 101 is connected to a mounting block 109, and the inner cavity of the mounting block 109 is provided with a sliding mechanism and a clamping mechanism, and the left and right side walls opposite to each other of the door lock body 101 are respectively provided with a first lock strike plate 103 and a second lock strike plate 104, a notch is provided on the front side of the first lock strike plate 103, and a moving handle 106 is slidably provided on the notch, and the moving handle 106 is connected to a side wall located in the inner cavity of the door lock body 101 and is provided with a moving groove 112, a notch is provided on the second lock strike plate 104, and a moving block 111 is provided on the notch, and the inner components of the door lock body 101 are fixed by screws 108. By moving the movable handle 106 up and down, the movable handle 106 can drive the connecting plate 115 to move. When the connecting plate 115 moves, it can move on the inclined slide groove 117 in the mounting block 109 with the assistance of the sliding block. When the connecting plate 115 moves upward, the lock head 105 can move inward, and when the connecting plate 115 moves downward, the lock head 105 can move outward. Therefore, it is more convenient to use and is easy for disabled people to use.

[0026] In a specific embodiment, a bearing 113 is provided on the movable groove 112, a rotating rod 114 is provided on the bearing 113, and a bearing 113 is provided at the other end of the rotating rod 114, and a connecting plate 115 is sleeved on the rotating rod 114. In this configuration, the installation position and components of the connecting plate 115 are determined, ensuring that the connecting plate 115 can move.

[0027] Furthermore, a rectangular notch 116 is provided at the bottom of the mounting block 109, and a connecting plate 115 is provided through the rectangular notch 116, and the other end of the connecting plate 115 is located at the sliding mechanism. In this configuration, the installation position of the connecting plate 115 in the mounting block 109 is determined, ensuring that the connecting plate 115 can move.

[0028] Furthermore, the sliding mechanism includes an inclined slide groove 117, and a sliding block is slidably arranged in the inner cavity of the inclined slide groove 117, and the sliding block is connected to the connecting plate 115. In this configuration, the installation position and components of the sliding mechanism are determined, ensuring that when the connecting plate 115 moves, it can move on the inclined slide groove 117 in the mounting block 109 with the assistance of the sliding block, and when the connecting plate 115 moves upward, the lock head 105 can move inward, and when the connecting plate 115 moves downward, the lock head 105 can move outward, so it is more convenient to use and is convenient for disabled people to use.

[0029] Furthermore, the clamping mechanism includes a mounting bar 118 and a ball 120. The mounting bar 118 is mounted on the side wall of the rectangular notch 116. Two symmetrical limiting grooves 119 are provided on one side wall of the mounting bar 118 close to the connecting plate 115. The two limiting grooves 119 and the ball 120 fit each other, and a return spring 121 is provided on the ball 120. The other end of the return spring 121 is connected to the side wall of the rectangular notch 116. In this arrangement, it is ensured that when the user moves the moving handle 106 downward and moves to a certain position, the lock head 105 can be released to keep unchanged and will not move further; at the same time, when the user moves the moving handle 106 upward to a certain position, it can be ensured that the moving handle 106 will not move.

[0030] The implementation principle of a sliding door lock of the present embodiment is as follows: first, the user moves the moving handle 106 up and down so that the moving handle 106 can drive the connecting plate 115 to move. When the connecting plate 115 moves, it can move on the inclined slide groove 117 in the mounting block 109 with the assistance of the sliding block. When the connecting plate 115 moves upward, the lock head 105 can move inward, and when the connecting plate 115 moves downward, the lock head 105 can move outward. Therefore, it is more convenient to use and is easy for disabled people to use.
