[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-6 A sliding door locking device includes a first sliding door 1 and a second sliding door 2 arranged side by side. A groove is formed on the side of the first sliding door 1 near the second sliding door 2. The groove is used to accommodate an insert plate 201 installed on the second sliding door 2 to achieve a locking fit. A cavity is formed inside the side of the first sliding door 1 near the groove. A movable plate 101 is slidably connected to the inner wall of one side of the cavity. Three locking blocks 103 are fixedly installed on one side wall of the movable plate 101. The three locking blocks 103 are located at the upper, middle and lower parts of the side wall of the movable plate 101, and one side of the locking blocks 103 extends into the groove of the first sliding door 1. A through hole is formed in the middle of one side of the first sliding door 1, extending into the cavity of the first sliding door 1. Movable blocks 102 are fixedly installed on the upper and lower parts of the side wall of the movable plate 101 near the through hole of the first sliding door 1 extending into the cavity. By pushing the movable blocks 102, the movable plate 101 can slide in the cavity.

[0022] An insertion plate 201 is welded to the side wall of the second sliding door 2 near the first sliding door 1. The insertion plate 201 matches the groove opened on the side wall of the first sliding door 1 and can be smoothly inserted into the groove. The insertion plate 201 has three slots 202, which correspond one-to-one with three blocks 103. The slots 202 match the blocks 103. When the second sliding door 2 approaches the first sliding door 1 and the insertion plate 201 is inserted into the groove, the moving block 102 can be pressed down to move the moving plate 101, which will cause the blocks 103 to be engaged in the slots 202, thereby locking the first sliding door 1 and the second sliding door 2.

[0023] Mounting grooves are provided on the upper and lower parts of the inner wall of one side of the cavity of the first sliding door 1. A spring 104 is installed in the mounting groove. A limiting plate 105 is installed on one end of the spring 104. A limiting block 106 extending into the cavity of the first sliding door 1 is installed on the side of the limiting plate 105 away from the spring 104. Two limiting grooves 107 are provided on the upper and lower parts of one side of the moving plate 101. The limiting block 106 is arc-shaped on the side of the cavity of the first sliding door 1, and the limiting block 106 is in line with the cavity of the first sliding door 1. The limiting groove 107 is matched. When the moving plate 101 slides, the limiting block 106 will move in the limiting groove 107. The elastic force of the spring 104 will keep the limiting block 106 in contact with the limiting groove 107, which will play a positioning role for the sliding of the moving plate 101. When the moving plate 101 is moved upward by pushing the moving block 102, the moving plate 101 can be limited. At this time, the locking block 103 can be disengaged from the locking groove 202, which makes it convenient to open the first sliding door 1 and the second sliding door 2 to both sides.

[0024] In addition, both the first sliding door 1 and the second sliding door 2 have through holes, and transparent glass 3 is installed in the through holes to facilitate observation of the other side of the sliding door. Different types of glass, such as frosted glass, can be installed as needed.

[0025] Example 2: Please refer to Figures 1-6 A sealing strip can be provided at the contact edge of the first sliding door 1 and the second sliding door 2. When the first sliding door 1 and the second sliding door 2 are locked, the sealing strip can fit tightly, improving the sealing performance of the sliding door and preventing dust, moisture and other substances from entering.

[0026] Meanwhile, locking status indicator devices are provided on the first sliding door 1 and the second sliding door 2. When the locking block 103 is inserted into the slot 202, the indicator device displays the locking status. When the locking block 103 is removed from the slot 202, the indicator device displays the unlocking status, so that users can understand the locking status of the sliding door in a timely manner.

[0027] Meanwhile, to ensure the reliability of locking, anti-slip textures can be provided on the contact surfaces of the locking block 103 and the slot 202 to increase the friction between the locking block 103 and the slot 202 and prevent the locking block 103 from sliding out of the slot 202 due to vibration or other reasons during use. If necessary, a through hole extending into the cavity of the first sliding door 1 can also be opened on the other side of the first sliding door 1, and a moving block 102 can be installed on the other side of the moving plate 101, so that the first sliding door 1 and the second sliding door 2 can be opened from both inside and outside.

[0028] Implementation effect: The first sliding door 1 and the second sliding door 2 are arranged side by side. The groove of the first sliding door 1 matches the insertion plate 201 of the second sliding door 2, providing a basic positioning for locking. The moving plate 101 slides in the cavity, driving multiple locking blocks 103 to move and precisely cooperate with the slots 202 on the insertion plate 201. This design of multiple locking blocks 103 and slots 202 greatly enhances the firmness of locking, effectively preventing the sliding door from being accidentally opened during use, and improving the safety and sealing of the space. At the same time, the through hole in the middle of the side wall of the first sliding door 1 and the setting of the moving block 102 make it convenient to operate the moving plate 101 from the outside, making the locking and unlocking process more convenient.

[0029] A spring 104 is installed in the mounting groove on the inner wall of the cavity of the first sliding door 1. The spring 104 is connected to the limiting block 106 through the limiting plate 105. The limiting block 106 matches the limiting groove 107 of the moving plate 101. During the sliding process of the moving plate 101, the limiting block 106 moves in the limiting groove 107. The elastic force of the spring 104 plays a buffering and positioning role. When the moving plate 101 is moved upward by pushing the moving block 102, the moving plate 101 can be limited. At this time, the locking block 103 can be disengaged from the locking groove 202, which makes it convenient to open the first sliding door 1 and the second sliding door 2 to both sides. In addition, the transparent glass 3 on the first sliding door 1 and the second sliding door 2 allows for easy observation of the other side of the sliding door without affecting the locking function, which improves the practicality and convenience of the device. Moreover, the door lock structure is a hidden design, which increases the aesthetics.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
