Description
The utility model relates to the switching device in a kind of padlock keyhole hole, promptly a kind of headstock gear of padlock keyhole.
The hole of button of traditional padlocks exposes, and its shortcoming one is very easily to stop up, thereby influences the unlatching of padlock, and the 2nd, improper unlatching padlock ratio is easier to its poor safety performance.
The switching device that the purpose of this utility model provides a kind of padlock keyhole hole with regard to being to avoid the shortcoming of prior art, this switching device can avoid hole of button blocked, improves the safety and the reliability of lockset.
The utility model is to adopt following measure to realize its purpose.
On the mandrel that forms by the supporting axis of guide and the coupling of slip lock shaft, be with the digital wheel that pivoted housing and digital adjustable overcoat make up in 2 to 6 numbers, slip lock shaft one end has the salient point of a shrinkage pool coupling on the switchboard of pegging graft with the lock body dovetail, the other end of slip lock shaft is connected with a compression spring, 2 to 6 rectangular teeths are arranged on the slip lock shaft, and between cog with digital in the endoporus flange coupling mutually of pivoted housing, have on the endoporus flange of pivoted housing in digital one can be axially open slot by rectangular teeth.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a main sectional view of the present utility model.
Fig. 2 be along A--A direction among Fig. 1 sectional view.
Fig. 3 is a vertical view of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
The accompanying drawing illustrated embodiment is the switching device that the padlock keyhole hole of 4 digital wheels is arranged.Form a mandrel of inserting in the lock body (3) by the supporting axis of guide (10) and slip lock shaft (14) coupling, be set with 4 digital wheels (13) on this mandrel, the lower end of slip lock shaft (14) is connected with a compression spring (11), there is a salient point (5) upper end, shrinkage pool (6) coupling mutually on the switchboard (1) of this salient point (5) and locking shape, switchboard (1) is gone up dovetail groove with lock body (3) and is plugged, 4 rectangular teeths (4) are arranged on the sliding shaft (14), digital wheel (13) is to be combined by pivoted housing (8) in 4 numbers and 4 adjustable overcoats of number (9), and the relative position of digital interior pivoted housing (8) and digital adjustable overcoat (9) can be adjusted according to the number of oneself selecting voluntarily by the user.In the endoporus of pivoted housing (8) flange with open slot (12) (7) is arranged in digital, the rectangular teeth (4) on the slip lock shaft (14) is inserted between adjacent flanges dish (7) and is gone up in the space (15).Rectangular teeth (4) can axially pass through the open slot (12) on the flange (7), but the open slot (12) on four flange (7) only all aligns, and with slip lock shaft (14) on rectangular teeth (4) on same straight line.Can pass through, at this moment, move down if outside pulling switchboard (1) slip lock shaft (14) will overcome the elastic force of spring (11), switchboard is opened, and hole of button (2) then reveals.
The utility model is simple in structure, makes easy to usely, and it can avoid hole of button blocked, improves the safety and the reliability of padlock.
