Description
Technical field
The utility model provides the assembly on a kind of lockset, the assembly on especially a kind of theftproof lock.
Background technology
The prior mechanical theftproof lock normally improves theftproof performance by the quantity (promptly increasing the lock point) that improves the pellet shot from a slingshot on the cage knob, and cage knob adopts incorporate design, and tongue piece is directly installed on the lock core.This lockset, the lawless person can insert steel disc and destroy pellet shot from a slingshot.Pellet shot from a slingshot is in a single day ineffective, and theftproof lock just can not play anti-theft effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of engaging type anti-theft lock button, to improve theftproof performance.
The utility model is to realize like this, engaging type anti-theft lock button, it has shell, the cage knob body is installed in the shell, the toothed driving wheel in upper end is installed in the cage knob body, there is loose wheel the driving wheel top, on the loose wheel, the lower end has last tooth and lower tooth respectively, there is the toothed follower in lower end the loose wheel top, and the follower upper end is equipped with the hyoid tooth sheet, between follower and the loose wheel spring is arranged, driving wheel, lock core is installed in the loose wheel, at the cage knob body, driving wheel, multiple tracks slotted eye aligned with each other is arranged on the lock core, spring and pellet shot from a slingshot are installed successively, in the slotted eye at the cage knob body, slotted eye aligned with each other is arranged on the loose wheel, spring and location pellet shot from a slingshot are installed in the slotted eye successively, the pellet shot from a slingshot back has the pellet shot from a slingshot piece to be installed on the lock core, and cage knob body inner surface has the groove that communicates with slotted eye, and groove also communicates with the translot of cage knob body inner surface above it.
Adopt the engaging type anti-theft lock button of said structure, adopted the trisome formula structure of driving wheel, loose wheel, follower,, lock can not be opened, thereby improve theftproof performance even pellet shot from a slingshot is destroyed.This cage knob can be used on the theftproof lock and other locksets of various security doors, safety cabinet, door lock for vehicle, vehicle.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the partial sectional view of the cage knob body in the utility model.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model and operating principle.
As shown in drawings, the engaging type anti-theft lock button of the utility model, it is characterized in that, it has shell (1), cage knob body (5) is installed in the shell, the driving wheel (4) of upper end band tooth (4-1) is installed in the cage knob body, there is loose wheel (6) the driving wheel top, on the loose wheel, the lower end has last tooth (6-1) and lower tooth (6-2) respectively, there is the follower (9) of lower end band tooth (9-1) the loose wheel top, the follower upper end is equipped with hyoid tooth sheet (10), spring (12) is arranged between follower and the loose wheel, driving wheel, lock core (15) is installed in the loose wheel, at the cage knob body, driving wheel, multiple tracks slotted eye aligned with each other is arranged on the lock core, spring (2) and pellet shot from a slingshot (3) are installed in the slotted eye successively, at the cage knob body, slotted eye aligned with each other (5-1) is arranged on the loose wheel, spring and location pellet shot from a slingshot (14) are installed in the slotted eye (5-1) successively, the pellet shot from a slingshot back has pellet shot from a slingshot piece (13) to be installed on the lock core, cage knob body inner surface has the groove (5-2) that communicates with slotted eye (5-1), and groove also communicates with the translot (5-3) of cage knob body inner surface above it.
Shown in Figure 1 is the firm situation of key having been inserted lock core and not rotated, and at this moment, each pellet shot from a slingshot is in equilibrium state.Key in this case, location pellet shot from a slingshot (14) moves along moving on the groove (5-2) in the translot (5-3) and in translot, thereby move on the drive loose wheel, the last tooth of loose wheel upper and lower end, lower tooth respectively with driving wheel, follower on tooth mesh together, driving wheel drives follower by loose wheel and rotates, and follower will drive the hyoid tooth sheet and rotate.The hyoid tooth sheet drives execution unit on the lockset (as the dead bolt bar etc.) and rotates, and lock is opened.When key rotated back into original position, loose wheel and master, follower broke away from.And behind the extraction key, keep disengaged position always.
Last tooth (6-1), the lower tooth (6-2) of described loose wheel upper and lower end are respectively straight-tooth and helical teeth, and the tooth (4-1) of driving wheel (4) upper end is a helical teeth, and the tooth (9-1) of follower (9) lower end is a straight-tooth.
Described hyoid tooth sheet can be tongue piece or gear piece.
As shown in drawings, even each pellet shot from a slingshot is destroyed,, the hyoid tooth sheet is rotated, thereby improved theftproof performance because loose wheel and driving wheel, follower are meshed together.
On the top of cage knob body spring (7) and locking ball (8) can be installed also.Jump ring sheet (11) can be arranged at follower top.
