Because the first locking mechanism 4 and the second locking mechanism 5 are designed to be screwed to each other In addition, the lock bolt 3 can be driven by the first locking mechanism 4 to be automatically positioned in the bolt groove 25 and the assembly hole 24, and no other tools or screws are required to perform the locking operation during the assembly process. Therefore, the lock of the present invention It has the effect of convenient assembly. Furthermore, the first positioning cylinder 41 and the second positioning cylinder 51 are screwed together, and the first elastic member 44 pushes the first positioning rod 46 with a buffering elastic force. The horizontal positioning lock bolt 3 can still be applied when the thickness of the door panel 2 is changed moderately. Therefore, the design of the lock of the present invention is not only convenient for assembly, but also widely applicable to the thickness of the door panels 2 of different door types currently on the market. It has better applicability and utility.

The lock of the present invention can also be applied to the door panel 2 with different opening directions, such as the door panel 2 opening left or right. Please refer to Figure 12. When the opening direction of the door panel 2 is opposite, just set the lock bolt 3 in the opposite direction. In the door panel 2, the assembled position of the first locking mechanism 4 and the second locking mechanism 5 remains unchanged. At this time, the second positioning rod 47 of the first locking mechanism 4 is inserted through the contact hole 332, and The second abutting wedge surface 471 is in contact with the edge of the abutting hole 332, and then the lock bolt 3 is retracted in conjunction with the door block 31 and the side edge 23 of the door panel 2, which can also drive the lock bolt. 3 Lateral positioning, therefore, the design of the second positioning rod 47 of the lock of the present invention can further improve the applicability of the lock.
