Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 4, a non-standard lock body includes a cover plate 1 and a panel 2, an opening 11 is formed on one side of the cover plate 1, the panel 2 is located on one side of the opening 11 of the cover plate 1, two ends of the panel 2 are bent towards one side of the cover plate 1 to form flanges 21, the cover plate 1 is covered with the flanges 21, a side wall of each flange 21 is a first installation reference edge 211, a side wall inside the cover plate 1 is a second installation reference edge 12, and an installation reference space 3 is formed between the first installation reference edge 211 and the second installation reference edge 12. In order to adapt to the use occasions with higher requirements of parts, the inclined tongue of the lock body is provided with the roller, so that the friction force between the inclined tongue and the door is reduced, the door is convenient to open, the integral length of the inclined tongue can be increased after the roller is arranged on the inclined tongue, and the inclined tongue cannot be completely accommodated in the lock body of the lock body produced according to the existing standard, so that the inclined tongue partially leaks out of the lock body, and the opening or closing of the door is influenced. If break the standard of current lock body, increase the length of lock body and remove to accept the latch bolt with the increase space, can lead to unable formation location between the panel of lock body and the mounting groove of door inner lock body, make the panel outstanding in the mounting groove of door, influence the whole aesthetic property of door to the panel outstanding in the installation of door also makes the side unevenness of door, can lead to lock body panel and human contact, leads to the cut, or when the human collision here, leads to the production of catching scheduling problem. In order to solve the above two problems, the non-standard lock body of the technical solution described in fig. 1-4 is to extend the length of the cover plate 1 to accommodate the latch bolt 5 after the length is increased, and to reset the existing installation reference distance 3, in the original design, the distance between the inner wall of the cover plate 1 and the inner wall of the panel 2 is the space that can be accommodated in the lock body, i.e. the installation reference distance, and now the existing installation reference distance is increased due to the increase of the length of the cover plate 1, and by designing the panel 2 with the flanging 21, the distance between the side wall of the flanging 21 and the inner wall of the cover plate 1 is just equal to the existing installation reference distance 3, so as to solve the problem that the lock body cannot be positioned during installation, although the installation groove of the lock body partially protrudes out of the door after being installed on the door due to the increase of the length of the panel 2, but because a gap exists between the door and the door frame, the gap can just accommodate the distance of the lock body protruding out of the mounting groove. In addition, after the flanging 21 abuts against the door side wall, the connecting edge can be better formed between the flanging and the door side wall, so that no gap exists between the flanging and the door side wall, and the integral safety factor is improved.

Furthermore, the connection part of the turned-over edge 21 and the panel 2 is arc-shaped, and the arc-shaped design of the transition part can prevent the human body from being scratched or bruised due to sharp edges and corners when the human body collides with the connection part.

Further, the width between the flanges 21 is larger than the width between the upper and lower bottom surfaces of the cover plate 1.

As shown in fig. 5, a connecting seat 4 is provided in the cover plate 1, a threaded hole 41 is provided on the connecting seat 4, and a through hole 22 corresponding to the threaded hole 41 is provided on the panel 2 and is connected to the cover plate 1 by a fastening member.

As shown in fig. 6, the cover plate 1 is internally provided with a latch bolt 5, the panel 2 is provided with a lock hole 23 for the latch bolt 5 to extend out, the cover plate 1 is internally provided with a square hole 6, the square hole 6 is internally connected with a square core 7, the square core 7 is provided with a latch bolt toggle piece 8 matched with the square core 7, and the latch bolt toggle piece 8 is connected with the tail end of the latch bolt 5. The square core 7 is formed with and rotates periphery 71, rotates and is equipped with shifting block 72 on the periphery 71, latch bolt stirring piece 8 be formed with rotate periphery 71 and mutually support rotate interior circumference 81, rotate interior circumference 81 with shifting block 72 laminates mutually, the both ends of rotating interior circumference 81 form spacing extreme point 82, spacing extreme point 82 with the rotation periphery 71 laminating of square core 7. The square core 7 is further provided with a limiting periphery 73, a limiting block 731 is arranged on the limiting periphery 73, and the limiting block 731 and the shifting block 72 form a limiting channel to limit the latch bolt shifting piece 8 therein. The latch bolt moving piece 8 rotates around the rotating periphery 71 of the square core 7 through rotating the inner periphery 81, the moving block 72 of the square core 7 drives the two limit end points 82 on the latch bolt moving piece 8 to enable the latch bolt moving piece 8 to control the movement of the latch bolt 5, in addition, a limit channel between the moving block 72 and the limit block 731 limits the position of the latch bolt moving piece 8, the latch bolt moving piece 8 only rotates in the appointed periphery, radial deviation cannot occur, the stability of movement is guaranteed, in addition, other parts are not needed to achieve the functions, and the accuracy of mutual matching is also guaranteed through relatively few matching parts.

Furthermore, a spring rod 9 is arranged in the cover plate 1, a rack 10 is connected to the spring rod 9, gear teeth 74 are formed on one side of the square core 7, the gear teeth 74 are meshed with the rack 10, and a return spring 13 is arranged on the spring rod 9. After each rotation of the square core 7, the return spring 13 drives the rack 10 to return through the spring rod 9, so that the square core 7 returns to the initial position.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
