Specifically, as shown in fig. 1-3, in one embodiment, the counter-striker shaft assembly 20 includes a spring plate 23 and a counter-striker shaft 24. Wherein, the shrapnel 23 is clamped and fixed with the positioning part 12, and one end of the reverse locking piece shaft 24 is fixedly connected with the shrapnel 23.
In the above arrangement, the locking piece shaft assembly 20 is rotated to the side where the slot 11 penetrates through the rotating shaft 14 and is taken out, and the elastic piece 23 is retracted and released from the positioning hole. Thereby realizing the quick disassembly of the connecting structure. Thereby improving the disassembly and assembly efficiency of the door lock.
Specifically, as shown in fig. 2, in one embodiment, the elastic piece 23 includes a connection body 231 and an elastic arm 232. Wherein, the connecting body 231 is provided with an inserting groove 2311, and the elastic arms 232 are respectively arranged at two sides of the connecting body 231. One end of the counter lock piece shaft 24 is fixed in the insertion groove 2311, and the two elastic arms 232 can be simultaneously clamped in the positioning holes to realize the fixed connection of the counter lock piece shaft assembly 20 and the counter lock knob 10.
Specifically, as shown in fig. 1, in one embodiment, one end of the counter bolt shaft 24 is fixedly connected to the spring plate 23, and the other end thereof is connected to the bolt of the door lock (the bolt is not shown). The lock is of a long strip structure and is convenient to match with the lock body, and a guide angle is arranged at one end of the counter lock piece shaft 24, which is connected with the lock body, so that the counter lock piece shaft is convenient to insert into the lock body.
Specifically, as shown in fig. 2, in one embodiment, the elastic sheet 23 has a Y-shaped structure. Of course, in an alternative embodiment not shown in the drawings of the present application, the resilient tab 23 may be provided as a T-shaped structure.
In the Y-shaped or T-shaped structure, the bottom vertical part is used for fixing with the counter lock piece shaft 24, and the fixing method can be welding, riveting, bonding and the like. The upper portion extends to the left and right sides with two elastic arms 232. The positioning holes are arranged at the corresponding positions on the two sides of the slot 11. When assembled, the elastic arm 232 is matched with the two sides of the elastic sheet 23, so as to play a role in fixing and positioning.
Specifically, as shown in fig. 3, in one embodiment, one end of the counter lock piece shaft 24 is provided with a positioning groove 241, and the connecting body 231 is fixed in the positioning groove 241.
It should be noted that, a positioning groove 241 is disposed at a matching position of the counter lock piece shaft 24 and the elastic piece 23, so that the elastic piece 23 and the counter lock piece shaft 24 are positioned when fixed, and the fixation is firmer.
Specifically, as shown in fig. 5, in an embodiment, a limiting portion 111 is disposed on a groove bottom of the slot 11, and the limiting portion 111 can axially limit the elastic sheet 23 to prevent the elastic sheet 23 from coming off from the positioning portion 12.
Specifically, as shown in fig. 5, in one embodiment, the position-limiting portion 111 is a protrusion disposed at the bottom of the slot 11. When the protrusion contacts the connecting body 231, the elastic arm 232 is clamped in the positioning hole. This prevents the spring arm 232 from being disengaged from the positioning hole due to excessive downward displacement of the counter-blade shaft assembly 20. Thereby improving the stability and reliability of the door lock connection.
