Abstract
The utility model discloses a blade lock core is opened to explosion -proof power, including the lock core body, being equipped with the crank slot of evenly arranging on the lock core body, being provided with the blade in the crank slot, offered the key hole in the middle of the blade, be equipped with first lug on the pore wall, blade one side is equipped with first support, is equipped with a reset spring, its characterized in that on the first support: have at least sets up in the crank slot open the blade for explosion -proof power, just this explosion -proof power is opened the blade and is had thickness more than the blade twice, explosion -proof power is opened the blade both sides and all is equipped with the second support, is equipped with the 2nd reset spring on the second support respectively, and explosion -proof power is opened and is equipped with the second lug on the key hole pore wall of blade. The utility model discloses a blade is opened to stainless steel injection moulding's explosion -proof power, can bear great destruction moment of torsion, has the effect that explosion -proof power was opened, has adopted the lug design of similar conventional blade simultaneously, has certain security.
Description
Technical field
The utility model relates to a kind of improvement invention of motorcycle lock, particularly relates to the improvement invention that a kind of explosion-proof power opens blade lock core.
Background technology
In prior art, the blade in motorcycle lock is common blade, adopts punch forming, because the thinner therefore intensity of material is lower, can not bear larger breakdown torque.Though conventional structure can meet the pertinent regulations about anti-theft device in GB17353-1998, namely the destruction driving torque of lock core is greater than 2.45N.m, can not meet the requirement preventing from opening by force.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides the explosion-proof power that a kind of intensity is high, assembly manipulation is simple, secrecy is high, cost is low to open blade lock core, can effectively prevent the violence of ignition switch from opening.
In order to solve the technical problem, the utility model adopts following technical scheme to realize: this kind of explosion-proof power opens blade lock core, include plug body, described plug body is provided with the crank slot be evenly arranged, blade is provided with in crank slot, keyhole is offered in the middle of blade, hole wall is provided with the first projection, blade side is provided with the first bearing, first bearing is provided with the first back-moving spring, it is characterized in that: have at least and setly in a crank slot open blade for explosion-proof power, and this explosion-proof power opens the thickness that blade has more than described blade twice, described explosion-proof power is opened blade both sides and is equipped with the second bearing, second bearing is respectively equipped with the second back-moving spring, and the keyhole hole wall that explosion-proof power opens blade is provided with the second projection.
As further improvement, it is stainless steel injection mo(u)lding that described explosion-proof power opens blade.
The beneficial effects of the utility model are that the explosion-proof power after improving opens blade lock core, the explosion-proof power of stainless steel injection mo(u)lding is adopted to open blade, thickness is more than the twice of other blade, larger breakdown torque can be born, there is the effect that explosion-proof power is opened, also there is the bump design of other blade simultaneously, there is certain confidentiality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure chart of the utility model blade.
Fig. 3 is the structure chart that the explosion-proof power of the utility model opens blade.
Detailed description of the invention
Drawings illustrate structure of the present utility model, further illustrate its details by reference to the accompanying drawings more below.This explosion-proof power opens blade lock core, include plug body 1, one end of plug body 1 is key 2 insertion end, the other end is installation end 3, described plug body 1 is provided with some crank slots 4 be evenly arranged vertically, the blade 5 that thickness matches is provided with in crank slot 4, keyhole is offered in the middle of blade 5, hole wall is provided with the first projection 6, first projection 6 matches with the tartar of key, be the code number design of blade, blade 5 side is provided with the first bearing 7, first bearing 7 is provided with the first back-moving spring, first back-moving spring is arranged in the spring eye of crank slot 4 one end, the outer end of the first back-moving spring to be connected on the first bearing 7, performance is opened in order to improve the explosion-proof power of lock core, have at least and setly in a crank slot 4 open blade 8 for explosion-proof power, and this explosion-proof power opens the thickness that blade 8 has more than described blade 5 twice, explosion-proof power is opened blade 8 both sides and is equipped with the second bearing 9 simultaneously, second bearing 9 is respectively equipped with the second back-moving spring, second back-moving spring is separately positioned in the spring eye at crank slot 4 two ends, the outer end of the second back-moving spring to be connected on the bearing of both sides second 9 respectively, avoid because thickness increase causes one-sided reset that beat clamping stagnation occurs, and the keyhole hole wall of explosion-proof power unlatching blade is also provided with the second projection 10 matched with key tooth flower, strengthen confidentiality, as preferably, it is stainless steel injection mo(u)lding that explosion-proof power opens blade 8, effectively gains in strength.
In the utility model, the lock core blade construction adopting this anti-violence to open up to 12N.m through its breakdown torque of overtesting, exceeds the requirement that anti-violence is opened far away, uses other instrument except key to be all difficult to open ignition switch, theftproof is guaranteed.Although explosion-proof power opens blade adopt stainless steel injection mo(u)lding, whole ignition switch only needs this explosion-proof power to open the function that blade just can realize anti-violence unlatching, and all the other all adopt common blade, therefore can not increase higher cost.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
