[0019] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0020] For examples, see Figure 1-4, the utility model provides a technical solution:
[0021] A lock body comprises a lock shell 1, a ground hook 2 is installed on the outer wall of the lock shell 1, a lock side plate 3 is installed on the outer wall of the lock shell 1, a linkage piece 4 is installed on the inner wall of the lock shell 1, and a square tongue piece 5 is provided on one side of the linkage piece 4 at a position corresponding to the lock shell 1, a limiting steel ball 6 is installed on the inner wall of the lock shell 1, an anti-lifting piece 7 is provided on the inner wall of the lock shell 1, an oblique tongue piece 8 is installed on the inner wall of the lock shell 1, a sky hook 9 is installed on the inner wall of the lock shell 1, an oblique tongue pick 10 is installed on the inner wall of the lock shell 1, a rotating shaft 11 is installed on the inner wall of the lock shell 1, and one end of the rotating shaft 11 is connected to a torsion spring 12, a limited return spring 13 is installed on the inner wall of the lock shell 1, a square tongue limiting piece 14 is installed on the inner wall of the lock shell 1, and a lock body bottom shell 15 is installed on the inner wall of the lock shell 1.
[0022] In this embodiment, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , and also includes a gear 16, which is installed on the inner wall of the lock housing 1, the ground hook 2 and the sky hook 9 are respectively located on the opposite outer walls of the lock housing 1, the lock side plate 3 is located on one side of the linkage piece 4, one end of the rotating shaft 11 passes through the lock housing 1 and extends to the inner wall of the lock housing 1 and is connected to a torsion spring 12, the limiting steel ball 6 plays a limiting role on the linkage piece 4, and the connection between the rotating shaft 11 and the lock housing 1 is a rotating connection.
[0023] The working process of the utility model is as follows: when the lock body designed by the present invention is in operation, when the door is pressed down to open, it is only necessary to press down the handle to drive the rotating shaft 11 to drive the anti-lifting piece 7, and the anti-lifting piece 7 drives the linkage piece 4. At the same time, the sky hook 9 and the ground hook 2 move upward synchronously under the action of the linkage piece 4. The opening at the limit steel ball 6 is a φ4.2 blind hole, and a φ4 steel ball and a spring are arranged in the blind hole to play the role of positioning the linkage piece 4 up and down; at the same time, a square tongue piece 5 is provided on one side of the linkage piece 4 in the pressed down state, and the lower tongue piece 5 is normally ejected in this state;
[0024] When the door is locked, it is only necessary to press down the shaft 11 to drive the reverse-lifting paddle 7, and the reverse-lifting paddle 7 drives the linkage piece 4. At the same time, the sky hook 9 and the ground hook 2 move downward synchronously under the action of the linkage piece 4. In the reverse-lifting state, the oblique tongue piece 8 is blocked by the linkage piece 4 and cannot be retracted, thereby preventing the card from being inserted. At the same time, in the reverse-lifting state, the lock cylinder is used to push out the square tongue piece 5, and the linkage piece 4 of the square tongue piece 5 moves up and down, and the lock cylinder movement is limited by the pull plate of the square tongue piece 5. At this time, the shaft 11 cannot rotate. After the lock cylinder pushes back the square tongue piece 5, the shaft 11 can rotate. In this state, the door can be opened normally.
[0025] At the same time, it also includes a gear 16, which is installed on the inner wall of the lock shell 1. Under the action of the gear 16, when the rotating shaft 11 is pressed down and lifted, the movements of the sky hook 9 and the ground hook 2 are opposite, thereby solving the problem that the existing handle design is inconvenient in actual installation and use and has certain limitations. In addition, the existing lock body lock tongue may be opened by inserting a card, which poses a certain safety hazard, thereby affecting its practicality.
[0026] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
