Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-3, an embodiment of the present utility model discloses a knob lock, which comprises an outer shell 1, a lock body 2 and an inner shell 3, wherein a lock cylinder assembly 11 for driving a lock tongue in the lock body 2 to lock is arranged on the outer shell 1, and one end of the lock cylinder assembly 11 penetrates through the lock body 2;

wherein, a knob member 31 is rotatably connected to the outer side of the inner housing 3, one end of the knob member 31 is detachably connected to the lock cylinder assembly 11, and the knob member 31 is connected to the outer housing 1 through a fixing member 32.

In some embodiments, the outer side surface of the inner casing 3 is further provided with a groove, the knob member 31 is rotatably connected in the groove, and the design of the groove is adopted, so that the knob member 31 can be ensured to be stored, the knob member 31 is prevented from protruding out of the outer side of the inner casing 3 to occupy space and affecting the appearance;

further, the fixing member 32 is disposed outside the knob member 31 and on the inner side surface of the inner case 3.

The fixing component 32 in this embodiment is an annular groove formed in the outer side of the knob member 31, and the annular groove is clamped with the annular groove.

On the basis of the above embodiment, the lock cylinder assembly 11 includes a lock cylinder and a shift lever connected to the lock cylinder, the shift lever is used for being connected with the lock body 2 and penetrating the lock body 2, and the free end of the lever portion 311 is provided with a jack 312 for being inserted into the shift lever.

When specifically unlocking, a user can realize unlocking by matching a key with the lock core assembly 11 and realizing locking movement of the driving lock body 2 after rotating the lock core assembly 11, and in the same way, the user can also drive the shifting lever to rotate indoors by rotating the knob piece 31 so as to realize driving the lock tongue in the lock body 2 to move, so that the problem of more convenience in indoor unlocking is achieved, and the structure is simpler.
