Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

The utility model discloses a back lock knob subassembly, refer to fig. 1-4, this kind of back lock knob subassembly including: the anti-lock knob 10, the lock panel 20, the base 30, the adapter shaft 40, and the connecting strip 50. A knob through hole is formed in the surface of the lockset panel 20, and the anti-locking knob 10 is fixedly arranged in the knob through hole; the lock panel 20 and the base 30 are fixedly connected, specifically, fixed by screws; the bottom of the back locking knob 10 is provided with a first groove 11, the top of the adapting shaft 40 is correspondingly provided with a first convex rib 41 which is suitable for being matched with the first groove 11, and the back locking knob 10 and the adapting shaft 40 are matched with each other through the first convex rib 41 and the first groove 11 so as to realize clamping and fixing; the bottom of the first rib 41 is provided with a step structure 42, and the step structure 42 abuts against the base 30 for limiting, so that the adapter shaft 40 is fixed in the axial direction; the connecting shaft 40 is fixedly connected with the connecting strip 50, and the locking knob 10 is fixedly clamped with the connecting shaft 40, so that the locking knob 10, the connecting shaft 40 and the connecting strip 50 are in linkage transmission.
