Description

Technical Field

[0001] The invention belongs to the field of lock assembly, and in particular relates to a special lock inversion structure and a lock assembly method. Background Art

[0002] like Figure 1-Figure 3 As shown, the small lock includes a lock shell 91 and a lock core 92. A rotation channel 911 is set in the lock shell 91. The lock core 92 is inserted in the rotation channel 911 and can rotate relative to the lock shell 92. A plurality of installation cavities 912 are arranged along the length direction in the lock shell 92. One end of the installation cavity 912 passes through the rotation channel 911, while the other end is non-penetrating to close the installation cavity 912, so there is no need to penetrate the other end of the installation cavity like a conventional lock, and a main cover in a lock disclosed in Chinese Patent No. CN202311717854.7 is used for sealing, or a sealing door in a lock disclosed in Chinese Patent No. CN201320062084.2 is used for sealing, so that the structure is simpler and the number of parts is reduced.

[0003] In addition, since one end of the installation cavity 912 is closed away from the rotating channel 911, it is necessary to set an assembly channel 914 through the side of the rotating channel 911 away from the installation cavity 912, so that when the lock core 92 is not installed, the spring 93 and the flat-head pin 94 can pass through the assembly channel 914 and the rotating channel 911 in turn and enter the installation cavity 912.

[0004] The existing small locks need to be assembled manually. Specifically, the assembly channel 914 is in a state where one end of the assembly channel 914 away from the rotation channel 911 is facing upward. Figure 1-Figure 3 The lock in the state shown is turned upward by 90°, and each set of springs 93 and flat-head pins 94 are respectively installed downward into the installation cavity 912, and then the round-head pins 95 are installed one by one into the alignment cavity 921 of the lock core 92 under the condition that the lock core 92 is deflected at a certain angle circumferentially, and the lock core 92 is gradually inserted into the rotating channel 911. When the lock core 92 is inserted to each flat-head pin 94, it is necessary to manually extend the ejector pin from the end of the rotating channel 911 away from the lock core 92 into the rotating channel 911 and press the flat-head pins 94 one by one, so that the flat-head pins 94 are pressed against the lock core 92. The pin 94 is fully extended into the installation cavity 912 to release the insertion restriction on the lock core 92. In addition, due to the circumferential deflection of the lock core 92, during the insertion of the lock core 92, each alignment cavity 921 will not be aligned with any installation cavity 912 to prevent the spring 93 from pushing the flat-head pin 94 into the alignment cavity 921. Finally, after the lock core 92 is installed in place, the lock core 92 is rotated to align each alignment cavity 921 with the corresponding installation cavity 912, and the flat-head pin 94 is pushed into the alignment cavity 921 under the action of the spring 93 to complete the locking.

[0005] The problem with the above assembly method is that manual assembly is required and the production efficiency is low. In addition, small locks are small in size and difficult to operate manually, which further reduces the production efficiency. Summary of the invention
