Abstract
The utility model relates to a novel elastic sheet burglarproof lock which is mainly composed of a lock core, a lock casing, an elastic sheet, a lock closing pipe, a dividing control card, a key, an elastic sheet spring, etc., wherein the electric sheet is processed with a plurality of notch grooves of the dividing control card; the lock core is processed with a dividing control card groove in the direction perpendicular to the motion of the elastic sheet; the dividing control card is arranged in the dividing control card groove, and the tail end of the dividing control card is clamped a push-out groove of the lock closing pipe; the front side of the dividing control card is provided with cutting shoulders; the lock closing pipe and the lock casing are tightly combined and fixed to each other. When the lock is unlocked, under the push of the push-out groove, the cutting shoulders of the dividing control card are clamped in the notch grooves of the dividing control card.
Description
Technical field
The utility model relates to a kind of novel clip type anti-theft lock tool, belongs to hardware machinery lockset industry.
Technical background
The spring-piece type lockset that is using at present, though have easy to process, advantage such as stain resistance is strong because design defect and mismachining tolerance, the overwhelming majority can be by technical opening.Though I provide three kinds of design schemes in patent application document (application number: 200420086219.X, 200520078263.0,200520078392.X), they can prevent technical opening effectively, reduce mutual opening rate.But consider the different demands of the scope of application, processing cost, production technology, stain resistance, existing spy provides a kind of novel clip type anti-theft lock tool.
Summary of the invention
Purpose of design of the present utility model is to provide that a kind of to have a stain resistance strong, has low mutual opening rate, and can prevent a kind of novel clip type anti-theft lock tool of technical opening.
Design principle of the present utility model is that a branch control card is installed in lock core, adopt the substep control principle, block shell fragment by a minute control card in advance when lock core rotates it can not be moved, then shell fragment just can touch locking mouth inwall, thereby realize substep control, prevent technical opening.
The technical solution of the utility model feature is: design is processed with a plurality of branch control card grooves of the notch on shell fragment.On lock core, process a branch control card slot perpendicular to the shell fragment direction of motion, the movable branch control card of one two sideband angle is installed in minute control card slot, divide the tail end of control card to be stuck in the release groove on the locking inside pipe wall, divide the front of control card to be processed into the cutting shoulder that can be meshed with the branch control card groove of the notch on the shell fragment.Locking pipe and lock housing are tightly fixed together.When key inserts and drives lock core and rotates, under the promotion of releasing groove, divide the control card to overcome elastic restoring force to the motion of shell fragment direction, the front end cutting shoulder of branch control card is stuck in the branch control card groove of the notch on the shell fragment.If when this lock key was opened, the last lower limb of shell fragment overlapped with the interface of lock core and locking pipe, lock can be opened; When if not this lock key is opened, divide the cutting shoulder of control card front end to be stuck in the branch control card groove of the notch on the shell fragment in advance, then after making lock core continue to turn over a little angle under the rotation of key, the last lower limb of shell fragment can touch the locking mouth edge of locking pipe, and lock core can't be rotated further.The cutting shoulder of this control card front end is being stuck in the branch control card groove of the notch on the shell fragment tightly already time-division, and shell fragment also can't move, thereby reach the purpose that prevents technical opening.
Advantage of the present utility model is to prevent the larceny that produces because of the technical opening lockset, thereby effectively improves the social stability factor.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Accompanying drawing 1 is the overall structure schematic diagram of the utility model embodiment;
Accompanying drawing 2 is the utility model embodiment blocking schematic diagrames when non-lock key opened;
Accompanying drawing 3 is the horizontal schematic diagrames of the overall structure of the utility model embodiment.
Embodiment
As shown in Figure 1, present embodiment mainly is by lock core 13, lock housing 1, locking pipe 7, shell fragment 9, divides control card 4, key 10, shell fragment spring 8, divides organic assembling such as controlling card back-moving spring 16 to constitute.On lock core 13,, 12 li a branch control card 4 is installed, is processed with at minute trailing edge of control card 4 and releases angle 3, release angle 3 and be stuck in 2 li of release grooves on locking pipe 7 inwalls at a minute control card slot perpendicular to branch control card slot 12 of the direction of motion of shell fragment 9 processing.Divide the front of control card 4 to be processed with cutting shoulder 5, on shell fragment 9 design be processed with a plurality of can with the branch control card groove of the notch 11 that minute cutting shoulder 5 of control card 4 front ends is meshed.When key 10 insertion lock cores 13 were opened, key 10 drove lock cores 13 rotations, and branch is controlled the effect that card 4 is subjected to release on the locking pipe 7 groove 2, overcame elastic restoring force to shell fragment 9 motions, made the trailing edge release angle 3 of branch control card 4 leave release groove 2.Make the cutting shoulder in front 5 of branch control card 4 be stuck in 11 li of the branch control card grooves of the notch on the shell fragment 9 simultaneously.Lower limb does not touch locking mouth 6 edges on the locking pipe 7 on this moment shell fragment 9, continues rotary locking cylinder 13, wait to turn over an angle after, shell fragment 9 edges can touch locking mouth 6 edges on the locking pipe 7.If use this lock key 10 to open, lower limb overlaps with the interface of lock core 13 and locking pipe 7 on the shell fragment 9, and lock can be opened; If when using non-lock key 10 to open, as shown in Figure 2, shell fragment 9 will be blocked by the locking mouth 6 on the locking pipe 7, lock can not be opened.Shell fragment 9 was tightly blocked and can not be struck by a minute control card 4 this moment, thereby realized that substep control reaches the purpose that prevents technical opening.The utlity model has excellent theftproof performance and lower mutual opening rate.
