Abstract
The invention relates to a combined mechanical anti-theft lock. According to the combined mechanical anti-theft lock, a blade lock and a mechanical coded lock are organically combined together. The defects that the blade lock is poor in prevention of technical unlocking and destructive unlocking are overcome, and the trouble that passwords of the mechanical coded lock may be forgotten and an unlocking process is complex is avoided. The combined mechanical anti-theft lock combines the advantages of a key lockset and the advantages of the mechanical coded lock as a whole, and achieves breakthrough in prevention of technical unlocking and destructive unlocking. Due to the fact that the combined mechanical anti-theft lock is compact in structure, the length, the width and the thickness of the combined mechanical anti-theft lock are 45*30*18mm or even smaller, and therefore the combined mechanical anti-theft lock is strong in applicability and capable of being applied to anti-theft doors, safe cases, bank vault doors and other important anti-theft places.
Description
Technical field
The invention belongs to lockset, particularly blade lock, mechanical code lock, they main elements, organically combine, and formed a kind of novel mechanical anti-theft lock.
Background technology
Conventional is cylinder lock, blade lock at present.In some important antitheft places, mechanical code lock is used more.Anti-technical, the anti-destructive of mechanical code lock is unblanked stronger than cylinder lock, blade lock, but mechanical code lock use there is no cylinder lock, blade lock is convenient.Therefore it is less that, mechanical cipher is locked in general antitheft place use.
Summary of the invention
The object of this invention is to provide a kind of mechanical lock technical, anti-destructive is stronger of preventing.
Realizing the technical solution used in the present invention is; It has adopted key not rotate, and key inserts after lock core, makes the breach of primary blades align the head of code-locking block, and Unlocking knob just can rotating opening door.When not being original key insertion lock core, the breach of any a slice primary blades does not align the head of code-locking block, and Unlocking knob just can not rotate.In the situation that there is no key, with unlocking tool, stir back blades, at this moment, because primary blades does not contact with code-locking block head, cannot feel the position of primary blades breach.Because primary blades breach both sides are provided with miniature little tooth, code-locking block head also has miniature little tooth, rotate Unlocking knob, cam promotes code-locking block and moves, the miniature little tooth engagement of the miniature little tooth in primary blades and code-locking block head, at this moment, primary blades can not move, unlocking tool can not make primary blades move, and does not reach the object of technology unlocking.The key of unblanking, it is just equivalent to one group of password of mechanical code lock, has been engraved on the key, has overcome memory cipher, the defect of rotation to code.
Combined machine theftproof lock of the present invention, comprises lock body, is located at primary blades in lock body, pays blade, is located at the servo-actuated U-shaped sheet spring in primary blades and is located at the V-arrangement sheet spring paid in blade, is located at the code-aiming block in lock body and is located at return spring and spring stack in code-aiming block, is located at power transmission shaft in lock body, is located at code-aiming catch and slide block on power transmission shaft, is located at the Unlocking knob that door is upper and power transmission shaft links together.They have formed combined machine theftproof lock.
It is characterized in that; Lock body is four sides inner hollow body, is inside divided into two lattice; In one lattice, be provided with primary blades, back blades, V-arrangement and U-shaped sheet spring; Key can not rotate after inserting back blades, and it promotes back blades and moves into place.At this moment, primary blades, under the drive of servo-actuated U-shaped sheet spring, is close together with back blades all the time, makes breach align the head of code-aiming block, and Unlocking knob can be rotated and open the door easily; Another lattice of lock body are provided with code-aiming block, return spring, spring stack, cam, power transmission shaft; After key inserts, power transmission shaft can rotate and open the door; Lock body can change profile according to the situation of the place of using and door.
Described combined machine theftproof lock, its primary blades is strip sheet.There is a breach on its one side, and there is miniature little tooth on the both sides of breach, in its one end, have a groove, and in one end insertion groove of servo-actuated U-shaped sheet spring and tighten up, U-shaped sheet spring can guarantee that primary blades leans against on back blades, servo-actuated with back blades; When lockup state, rotate Unlocking knob, the little profile of tooth of code-aiming block head will with primary blades on little tooth engagement, primary blades can not be moved, and back blades can move after overcome friction; Stir back blades, can only make the U-shaped sheet spring distortion of primary blades, can not make primary blades move.
Described combined machine theftproof lock, back blades is strip sheet; There is key on its one side, and has the wedge shape of a protrusion; At the edge of wedge shape, have a sulculus, one end of V-arrangement sheet spring is inserted in sulculus and is tightened up; V-arrangement sheet spring makes back blades lean against one side of lock body all the time, after key inserts, can lean against reliably in key teeth groove.
Described combined machine theftproof lock, its code-aiming block is T-shaped; Its head is provided with little profile of tooth, corresponding with the little profile of tooth of primary blades when lockup state, and while rotating Unlocking knob, they can mesh together, and primary blades can not be moved; Code-aiming block is provided with return spring and spring stack, and after door is opened, code-aiming block is under the effect of spring force, exit primary blades breach, after key is extracted, primary blades is under the promotion of V-arrangement sheet spring, lean against the side of lock body, breach and the dislocation of code-aiming block head, the state in locking.
Described combined machine theftproof lock, cam is to remove on one side on cylindrical, forms cam; When lockup state, its rotation, will promote code-aiming block and move, and the head of code-aiming block is pressed on blade, cannot be rotated further.Only, after key inserts, the breach on blade and code-aiming block head align, and code-aiming catch can rotate under the drive of power transmission shaft.
Described combined machine theftproof lock, power transmission shaft is Step Shaft, removes two limit circular arc portions with the processing of cam contact portion, and cam can not freely be rotated; The mode that power transmission shaft has adopted inner nut to connect, can effectively prevent that external force from extracting power transmission shaft.After cure process, can be anti-drilling.
Described combined machine theftproof lock, base plate, through cure process, has anti-drilling function.
Described combined machine theftproof lock, Unlocking knob can be circular, also can make as required other shapes.
The invention has the beneficial effects as follows; Blade lock, mechanical code lock are organically combined.Overcome the anti-skilled unlocking of blade lock and the anti-destructive not strong defect of unblanking, overcome that mechanical code lock likely forgets Password and the defect of the trouble of unblanking; It integrates the advantage of lockset and coded lock, at anti-technical, anti-destructive, on opening, has realized breakthrough.Due to its compact conformation, length and width are thick is; 45 * 30 * 18mm, applicability is strong, can be used for security door, safety cabinet, bank exchequer door and other important antitheft places.
