Description
Technical field
The present invention relates to lockset, particularly a kind of theftproof lock.
Background technology
Lock is common anti-theft tool.Cylinder lock is simple in structure with it, practical and be widely used.The structure of cylinder lock is roughly the same, and one group of cylinder-shaped marble is housed in the marble hole of lock core, has on the key the tartar of respective depth.The mode of unblanking is also roughly the same, moves up and down the corresponding pellet of post by the height difference of key tooth flower, makes the height of each lock core marble be in the interface place on lock housing and lock core, then rotates key band movable lock core, reaches the object of unblanking.This class is latched in moving tooth passage, moves sub-in the situation that not touching, and foreign matter can enter keyhole the inner easily, probes into various unlocking tools by moving tooth passage, carries out skilled unlocking.This kind of effective travel that structure has been wasted pellet simultaneously, diminishes lockset key density, is easily opened by locksmith, and safety is poor.In view of above defect, people have developed blade lock.The principle of blade lock is exactly to utilize on the key bevel angle to change different tartars to rotate angle in alignment lock core and change different blades, thereby realizes the one lock that lock core rotarily opens.Chinese patent 200810031948.8,201020682555.6,200920303724.8 etc. all discloses the blade lock with anti-theft feature.But there is the defect such as complex structure, fault rate height in the disclosed blade lock of above-mentioned patent, and can not effectively prevent technical unlocking, and anti-theft effect is also not fully up to expectations.Therefore improvement and bring new ideas is imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the present invention's object is just to provide a kind of theftproof lock, can effectively solve billiards lock structure complexity, the problem that anti-theft effect is poor.
The technical scheme that the present invention solves is, comprise lock body and lock core, lock core is contained in lock body intracardiac, in lock body lower inner wall, there is mobile pearl brake hole, lock core central cross has first to move the hole of bead, lock core bottom have move with first that the hole of bead is connected second move the hole of bead, the center line that the first center line and second that moves the hole of bead moves the hole of bead is vertical, in lock core top, have and be positioned at first and move hole of bead top, and move with first the keyhole that the hole of bead is connected, first move in the hole of bead, be equipped with can move left and right first move pearl, first moves pearl top the cylindrical protrusions that stretches into keyhole, first moves on the bottom of pearl and has some draw-in grooves, second moves and in the hole of bead, is equipped with moving up and down second and moves pearl, second moves pearl top the projection consistent with draw-in groove shape, second moves pearl bottom the cambered surface consistent with flat pearl brake hole shape.
Novel structure uniqueness of the present invention, simple in structure, easy to operate, anti-theft feature is strong, and cost is low, has good society and economic benefit.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Provided by Fig. 1-Fig. 8, comprise lock body and lock core, lock core 2 is contained in lock body 1 intracardiac, in lock body 1 lower inner wall, there is mobile pearl brake hole 5, lock core 2 central cross have first to move the hole of bead 6, lock core 2 bottoms have move with first that the hole of bead 6 is connected second move the hole of bead 7, the center line that the first center line and second that moves the hole of bead 6 moves the hole of bead 7 is vertical, in lock core 2 tops, have and be positioned at first and move 6 tops, the hole of bead, and move with first the keyhole 8 that the hole of bead 6 is connected, first move in the hole of bead 6, be equipped with can move left and right first move pearl 3, first moves pearl 3 tops the cylindrical protrusions 12 that stretches into keyhole 8, first moves on the bottom of pearl 3 and has some draw-in grooves 9, second moves and in the hole of bead 7, is equipped with moving up and down second and moves pearl 4, second moves pearl 4 tops the projection 11 consistent with draw-in groove 9 shapes, second moves pearl 4 bottoms the cambered surface 10 consistent with flat pearl brake hole 5 shapes.
In order to ensure result of use, described projection 11 is conical;
Described draw-in groove 9 is inverted " V " font;
The projection 11 that only has a draw-in groove and second to move pearl 4 tops in described some draw-in grooves 9 matches, and is greater than the degree of depth of other draw-in grooves with the degree of depth of projection 11 draw-in grooves that match;
Described first moves pearl 3 and second moves pearl 4 and has parallel uniform several, each being all placed in the corresponding mobile hole of bead, and stagger successively in the each first position of moving a draw-in groove of pearl 3 bottom degree of depth maximums.
Service condition of the present invention is:
Normal unlatching, after key inserts, the each first cylindrical protrusions 12 that moves pearl 3 tops can move to consistent position according to the serpentine track matching on the key, now each first move pearl 3 bottoms and second move the consistent draw-in groove of pearl 4 upper lobes 11 be placed in second move the hole of bead 7 directly over, rotation key band movable lock core 2 rotates, under the effect of thrust, make second to move pearl 4 and move the hole of bead 7 along second and move to the direction of draw-in groove, because now second to move the projection 11 on pearl 4 tops consistent with the shape of draw-in groove, second moves pearl 4 can exit mobile pearl brake hole 5 completely, therefore rotary locking cylinder 2 smoothly, complete normal unlatching.
Unnormal unlocking (antitheft):
When being attempted to stir some first by foreign matter while moving pearl 3, now second move pearl 4 and under self gravitation effect, drop in the mobile pearl brake hole 5 on lock body 1 inwall, and lock body is without spring design, now first move pearl 3 and can expeditely move in the hole of bead 6 and move left and right first, make operator cannot locate this first position of moving pearl 3; In the time attempting rotary locking cylinder 2 by foreign matter, inevitable under the effect of thrust, can cause all second to move pearl 4 and move the hole of bead 7 along second and move to draw-in groove 9 directions, now, the second projection 11 that moves pearl 4 tops enters first and moves the more shallow draw-in groove of pearl 3 bottoms, cause second to move pearl 4 and cannot exit the mobile pearl brake hole 5 on lock body 1 completely, thereby cannot rotary locking cylinder, do not reach purpose of opening.
Novel structure uniqueness of the present invention, simple in structure, easy to operate, anti-theft feature is strong, and cost is low, has good society and economic benefit.
