Abstract
The utility model discloses an anti-theft blade lock. The lock pin of the anti-theft blade lock is provided with a press pin groove directly connected with a press pin spring. Compared with the existing lock pins, the lock pins of the anti-theft blade lock only need to be provided with one pressing pin spring, and balls do not need to be arranged. Therefore, materials can be saved, time is shortened, efficiency is improved, and therefore the cost of the lockset is reduced. And, because the pressure round pin spring mounting is in the pressure round pin inslot, the removal of lockpin is more steady, and this tool to lock is more reliable durable.
Description
Technical field
The utility model relates to lockset, particularly Anti-theft vane 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 namely 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, and namely the height difference by key tooth flower moves up and down the corresponding pellet of post, makes the height of each lock core marble be in interface place on lock housing and the lock core, and then screw key band movable lock core reaches the purpose of unblanking.This class is latched in the moving tooth passage, and in the situation of not bumping the son of moving, foreign matter can enter keyhole inside easily, probes into various unlocking tools by the moving tooth passage, carries out violence and unblanks.This kind structure has been wasted the effective travel of pellet simultaneously, and the lockset key density is diminished, and is opened by the locksmith easily, and safety is relatively poor.In view of above defective, people have developed blade lock.The principle of blade lock is exactly to utilize the different on the key tartars different blade in the lock core that aligns, thereby realizes a kind of 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 the lock core requirement on machining accuracy of above-mentioned blade lock is high, working (machining) efficiency is low and be difficult to guarantee crudy, and cost of production is higher.
The utility model content
According to an aspect of the present utility model, Anti-theft vane lock is provided, comprising:
Lock housing, the lock housing sidewall is axially arranged with the lock housing storage tank;
Lock core, be sheathed in the lock housing, the front end of lock core is provided with keyhole, lock core radially is provided with the blade groove that runs through, lock core is provided with the lock core storage tank corresponding with the lock housing storage tank vertically, is provided with lock pin in the lock core storage tank, and the lock pin bottom has jut, lock pin top has the pad groove, is provided with the pad spring in the pad groove;
Vane group, be located in the blade groove, comprise two blades, the top of blade is provided with the groove that the jut with the lock pin bottom is complementary, the middle part of blade is provided with can be for the interspersed tartar hole of key, and the top in tartar hole is provided with double wedge, and the position that the bottom of blade keeps left or keeps right is provided with pin, two blades in the same vane group mutually stack and the pin of two blades about relatively, be provided with back-moving spring between the pin of two blades.Adopt the Anti-theft vane lock of above technical scheme, its lock pin is provided with one and the direct-connected pad groove of pad spring.Relatively existing lock pin, each lock pin only need be installed a pad spring, need not to install pellet.Thus, can save material, the shortening time, raise the efficiency, thereby reduce the cost of this lockset.And because the pad spring fitting is in the pad groove, the movement of lock pin is more steady, and this lockset is more reliability and durability.
After the key that is complementary is inserted through blade tartar hole from the keyhole of lock core, key tooth flower acts on the blade convex teeth portion, make each blade in the vane group overcome the effect of back-moving spring and move to the lock core center, thereby make the groove of blade upper surface overlapped and be in same straight line.Lock pin moves down and matches with the blade groove, and this moment, lock core can rotate, and lockset is opened.When the key that is complementary is extracted from the keyhole of lock core, each blade in the vane group departs from the lock core center under the effect of back-moving spring, thereby the groove that makes the blade upper surface staggers mutually and make progress the pushing tow lock pin, lock pin is stuck between lock core storage tank and the lock housing storage tank, this moment, lock core can't rotate the lockset locking.
In some embodiments, lock core is provided with dovetail groove.Have inserted sheet in the dovetail groove, inserted sheet inserts and is fixed in the dovetail groove.The pad both ends of the spring contacts with pad groove and inserted sheet respectively.Lock core can be assembled separately, only needs during the lockset assembling lock core is inserted lock housing, and this lockset is easier for installation thus.
In some embodiments, lock pin is provided with V-shaped groove along its length.When the groove of blade upper surface staggered mutually, blade pushing tow lock pin entered the lock housing storage tank, and lock pin is stuck between lock core storage tank and the lock housing storage tank.If use the foreign matter forced rotating lock cores such as steel disc this moment, the seamed edge that lock housing storage tank and lock-shell lining form will snap in the V-type groove on the lock pin, and lock pin can't be moved in the lock core storage tank.Thus, this lockset can avoid violence to open, and theftproof performance is better.
In some embodiments, the blade pin is obliquely installed.Thus, the blade pin can fully contact with the end of back-moving spring, thereby makes vane stress even, and back-moving spring is not easy to wear
In some embodiments, keyhole integral body is rectangle, and the middle part, top is provided with the jut that extends to the center.
In some embodiments, V-shaped groove is two, is located at respectively on two relative faces of lock pin.
In some embodiments, the cross section of the jut of lock pin bottom is triangle.
