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. 1-3, a door lock includes a lock body panel 10 and a lock case 20, a connecting surface 201 is disposed on one side of the lock case 20 close to the lock body panel 10, a mating surface 101 corresponding to the connecting surface 201 is disposed on the lock body panel 10, and the lock case 20 is fixed on the mating surface 101 of the lock body panel 10 through the connecting surface 201. Specifically, the utility model discloses the lock includes lock body panel 10 and lock shell 20, and the oblique tongue and the square tongue that correspond in the lock shell 20 are followed lock body panel 10 respectively and are stretched out, and its lock shell 20 connect face 201 and lock body panel 10's fitting surface 101 through welding or bonding connection together, avoid to need the installation foot position can't be corresponding with the lock shell connecting hole, and lead to the phenomenon of unable connection lock shell, and through connecting face 201 and fitting surface 101 fixed connection, its connection structure is more firm.

Further, the connection surface 201 and the mating surface 101 are connected together by welding. Specifically, the connecting surface 201 is fixed on the mating surface 101 by welding, and the welding area is large, so that the mounting feet do not need to be welded in a concentrated manner, and welding marks are not easy to generate on the back surface of the lock body panel 10.

Further, the connecting surface 201 and the mating surface 101 are bonded together by glue. Specifically, the lock body panel 10 and the lock shell 20 can be connected together through some metal bonding glue, so that welding marks caused by welding are avoided.

As shown in fig. 2, the mating surface 101 is formed with a guide groove 102 that mates with the connection surface 201. Specifically, when the lock body panel 10 is welded to the lock case 20, the welding rod is welded along the guide groove 102 in the mating surface 101, so that the displacement is not easy to occur.

Furthermore, the upper end and the lower end of the connecting surface 201 on the matching surface 101 are both provided with a limiting bump 103. Specifically, when the lock case 20 is installed on the lock body panel 10, the limiting protrusions 103 abut against the upper and lower ends of the lock case 20 to help position the lock case 20.
