Description
Technical field
The utility model is related to Lock for vehicle field, especially a kind of safe antitheft lock.
Background technology
The characteristics of lockset of the vehicles such as bicycle, motorcycle needs to have safe antitheft.The China of the applicant's application is specially
Profit 2016100268014 discloses the lockwheel cast bicycle lock that a kind of hand closes electric-opening, and eccentric dialling is driven using motor
Bar makees arching trajectory motion, stirs catch yaw motion, and locking boss departs from locking bar locking mouthful, in the presence of a tensile force fast certainly
It is dynamic to unlock.But in actual use, because catch still suffers from certain free degree under elastic pressure effect, therefore in locking shape
If subjected to the vibration such as percussion, shock, catch deflects causes locking boss to depart from locking bar locking mouthful, can also hold under state
Lock, thus the requirement of safe antitheft can not be met.
Utility model content
A kind of the shortcomings of the applicant can be unlocked for above-mentioned existing lockset by impact shock, there is provided peace rational in infrastructure
Full anti-theft vehicle lock, carries out spacing in lockup state using block is insured to catch, so as to prevent resilience by mistake, increases the safety of lockset
Anti-theft.
The technical scheme that the utility model is used is as follows：
A kind of safe antitheft lock, including housing, arc-shaped lock bar, catch and thumb wheel, the locking boss of catch snap in locking bar
The existing locking of locking cause for gossip, the driving lever being arranged on thumb wheel promotes catch deflect realization unlocking centered on axle, in thumb wheel side
Be provided with insurance block, insurance block one end is articulated on housing, the extension top for insuring block is provided with projection, projection with
Block step surface is formed between extension；Thumb wheel step surface is formed on thumb wheel；The extension bottom of block is insured in the lockout condition
Face is located on the lower plane of thumb wheel, and the tail end away from axle of catch is above extension and spacing by block step surface.
As the further improvement of above-mentioned technical proposal：
The thumb wheel half portion thinner thickness formation lower plane, plane in another thicker formation of half portion thickness, upper plane is with
Thumb wheel step surface is formed between plane.
The insurance block is resetted with catch using elastomeric element.
The beneficial effects of the utility model are as follows：
The utility model is by increasing insurance block, and the shape of thumb wheel is improved, so as in the tail end of catch
It is spacing when carrying out locking, prevent lockset from being opened by mistake lock situation by impact shock；Thumb wheel pushes insurance block open before unlocking, then
Catch is promoted to be unlocked again, it is achieved thereby that automatically terminating the function of insurance.The utility model delicate structure, action is reasonable,
Effectively increase the safe antitheft and ease for use of lockset.

Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.
As shown in figure 1, safe antitheft lock described in the utility model includes arc-shaped lock bar 4, it is provided with the rear end of locking bar 4
Locking mouthful 6, catch 3 is pivoted around axle 7 and resetted using elastomeric element, and catch 3 is provided with locking boss 5 near one end of axle 7, closes
Locking boss 5 snaps in locking mouthful 6 during lock, realizes the locking to locking bar 4.Side and thumb wheel 2 of the catch 3 away from one end of axle 7
Driving lever 21 is contacted, and when thumb wheel 2 rotates, the driving lever 21 of eccentric setting promotes catch 3 to be deflected centered on axle 7.Set in the side of thumb wheel 2
Insurance block 1 is equipped with, as shown in figure 4, insurance block 1 one end is articulated on housing 8 by axis hole 14, and using elasticity such as torsion springs
Member reset, the top of extension 13 is provided with projection 11, and block step surface 12 is formed between projection 11 and extension 13.Such as Fig. 5
Shown, the thickness circumferentially of thumb wheel 2 is simultaneously differed, and half portion thinner thickness forms lower plane 23, another thicker shape of half portion thickness
Into upper plane 22, thumb wheel step surface 24 is formed between upper plane 22 and lower plane 23, driving lever 21 is additionally provided with thumb wheel 2.Such as Fig. 5
With the top of lower plane 23 that the bottom surface of extension 13 for shown in Fig. 1, insuring block 1 after assembling in the lockout condition is located at thumb wheel 2, gear
The tail end away from axle 7 of piece 3 is located at the top of extension 13 and is propped up by the block step surface 12 of insurance block 1, it is impossible to produce again
Such as anticlockwise deflection of Fig. 1 views, thus the situation that locking boss 5 is exited from locking mouthful 6 will not occur, so as to realize
Insurance during locking.
As shown in Fig. 2 when preparing to unlock, thumb wheel 2 first rotates to an angle, and is contacted in driving lever 21 and drives catch 3 inclined
Before turning, thumb wheel step surface 24 in advance insure the side of extension 13 of block 1 and outwards push insurance block 1 open by contact, until protecting
Dangerous block 1 is fully located at outside thick portion's outer peripheral face 25 of thumb wheel 2, and now the tail end of catch 3 is also departing from the block of insurance block 1
Step surface 12 is spacing, such that it is able to deflect.As shown in figure 3, thumb wheel 2 continues to rotate, driving lever 21 drives catch 3 to deflect, and keeps off
The locking boss 5 of piece 3 is exited from locking mouthful 6, and locking bar 4 is retracted into housing 8 and realizes unlocking in the presence of a tensile force.
Unlock after thumb wheel 3 turn round, insure block 1 extension 13 have left thick portion's outer peripheral face 25 it is spacing after in elasticity
The lower revolution of power effect, manual drive locking bar 4 circumferentially detour by track during locking, when 6 in-position of locking mouthful, in elastic masterpiece
Resetted with lower stop piece 3, locking boss 5 snaps in locking mouthful 6 and realizes locking, now insurance block 1 resets and form again such as Fig. 1 institutes
That shows is spacing for the tail end of catch 3.
The utility model is improved based on earlier application, and the published technology in part is referring to earlier application.For accompanying drawing
Description is needed, and upper and lower, left and right the definition of this paper is defined according to accompanying drawing, is not the absolute limitation to mutual alignment.More than retouch
State be not the restriction to utility model to explanation of the present utility model, without prejudice to the utility model spirit in the case of, this
Utility model can make any type of modification.
