Description
Technical field
The present invention provides a kind of mechanical lock, in particular for the door lock on bin, category lock and its accessories technical field.
Background technology
For safe antitheft, it usually needs lockset is installed on switch cubicle, the lockset that switch cubicle is equipped with mostly is mechanical
Structure door lock.In the door lock of this structure, because lock core marble and key coordinate for the rigid friction of machinery, so easily causing
The abrasion of lock core marble, so as to reduce the service life of lockset.Further, since the secret key rate of mechanical lockset is low, key compatibility
Easily repeat, non-lock key can all enter lock core, easily cause that key is mutually opened and key tooth is not opened mutually not etc., cause its theftproof performance
It is poor.Also, this key can be prepared arbitrarily, once key loss, to prevent hidden danger, can only re-replace lockset,
Using extremely inconvenient.In addition, pellet end is exposed and impulse stroke is short, and pellet can be touched directly by foreign matter (steel wire hook etc.)
And easily opened by technology.
The content of the invention
The present invention is directed to the drawback of prior art, there is provided a kind of antitheft mechanical safety lock, its simple in construction, security is with preventing
The property stolen is stronger.
Technical problem of the present invention solves by the following technical programs：
A kind of antitheft mechanical safety lock, including latch bar, the latch bar by bolted splice in clutch discs, it is described from

Set is connected with base axle sleeve by engaging tooth, and clutch discs axle sleeve is socketed on mandrel with base axle sleeve, at the top of the mandrel
Provided with axle sleeve, the spring on mandrel that spirals is provided between axle sleeve and clutch discs, ladder is provided between the clutch discs and base
Groove, the interior fork provided with size matching of step trough, base axle sleeve bottom is provided with lockhole.
Above-mentioned antitheft mechanical safety lock, the clutch discs are provided with arc gap, central angle corresponding to the arc gap
For α, α is 50-70 °, is provided with alignment pin in arc gap, the alignment pin is fixed on base.
Above-mentioned antitheft mechanical safety lock, the plug connect handle by pilot pin, and pilot pin top protrudes the table of plug
Face, the neck matched with pilot pin is set in clutch discs.
Above-mentioned antitheft mechanical safety lock, one end of the plug are provided with two gear shapings, and the other end is provided with handle, gear shaping rip cutting
Face is the triangle of top surface inclination, and the joint face of two gear shapings is circular arc, and the radius of circular arc is equal to the external diameter of clutch discs axle sleeve.
Above-mentioned antitheft mechanical safety lock, the side surface of base one are provided with guide rail, and the two bottom sides of the plug are set respectively
There is inserted sheet, inserted sheet matches with guide rail size.
Above-mentioned antitheft mechanical safety lock, clutch discs axle sleeve put with datum axle and are provided with engaging tooth and engaging tooth with being respectively separated
Groove, the engaging tooth is with engaging slot size matching.
Above-mentioned antitheft mechanical safety lock, the hinge hole set 3, and 3 hinge holes are located on same circle, and its
In the lines of two hinge holes cross the center of circle, another hinge hole is equal with the distance between two hinge holes.
Above-mentioned antitheft mechanical safety lock, bearing connects between base and the base axle sleeve.
Above-mentioned antitheft mechanical safety lock, the latch bar in the vertical direction are in downward step type, in the vertical direction
In the fold-line-shaped of bending.
The present invention has advantages below：
The present invention is used cooperatively by mechanical key and electromagnetism key, realizes the closing and unlatching of lock, when lock closing,
When mechanical key insertion lockhole is unlocked, because the base axle sleeve for connecting lockhole is in released state with the clutch discs on lock core, this
When rotate mechanical key and can only realize the rotation of base axle sleeve, lock core will not rotate, and thus avoid conventional lock can be by foreign matter (steel
Silk hook etc.) stretch into situation about prying open.When needing to unlock, electromagnetism key controller plug detaches the step trough under clutch discs, clutch
The support of disk disappears, and clutch discs mutually reconnect with base axle sleeve, and now, mechanical key rotates, and drives clutch discs to rotate together,
Latch bar is set to leave locked groove, the cabinet door of switch cubicle is opened, and the mode that this double key control is unlocked, is effectively improved lock body
Safety and theftproof performance.
