Abstract
The invention discloses a lock head, and aims to solve the problem of low theftproof performance of the conventional blade lock which can be technically unlocked by using a hook. The lock head is characterized in that: a circular through hole (11) which passes through a lock body (1) and a lock cylinder (2) is formed in the side walls of the inner ends of the lock cylinder (2) and the lock body (1) in a radial direction; an anti-shifting ball (12) with a conical top, a flat-head ball (13) and a spring (14) are arranged in the circular through hole (11) sequentially; the flat-head ball (13) and the circular through hole (11) are in clearance fit with each other; and the spring (14) is plugged by a sealing door (15) embedded in the lock body (1). According to the lock head, relative rotation between the lock cylinder and the lock body is eliminated, so that the lock head cannot be technically unlocked by tools, such as the hook, and the anti-theft performance is improved; and the lock head has a simple structure, and is convenient to machine and low in cost.
Description
Technical field
The present invention relates to a kind of lockset, be specifically related to a kind of tapered end.
Background technology
Blade lock is common a kind of lockset, be widely used in security door, arrangements for automotive doors, safety cabinet, lock for motorcycle etc., blade lock mainly is comprised of lock body and lock core, blade and leaf spring are installed on lock core, the inwall of lock body is provided with the notch corresponding with two external parts of blade, tooth-engraved key in adopting, the tartar of key is driveed the both sides of the groove in the side, and this tartar is in the field of business also referred to as snakelike tartar.There is following defective in this blade lock: because the notch on blade and lock body is gapped, after extracting key, lock core and lock body pin, there be small relatively rotating between lock core and lock body, stretch in lock core with instruments such as hooks and can stir blade, blade is dragged in lock core one by one, realize technology unlocking; Therefore, cause existing blade lock theftproof performance poor.
Chinese patent CN201020128744.9 provides a kind of composite theftproof lock core, and this patent also proposes identical technical problem, but the lock core structure of this patent is complicated, and difficulty of processing is large, and cost is high.Chinese patent CN200920167359.2 provides a kind of V-type composite lock core, although also solved the problem of technology unlocking, lock core structure is complicated, difficulty of processing reaches greatly the high defective of cost but still exist.
Summary of the invention
Can utilize hook to carry out technology unlocking in order to overcome existing blade lock, the deficiency that theftproof performance is poor, the invention provides a kind of simple in structure, tapered end of being convenient to process, this tapered end arranges the anti-pellet of dialling on original blade lock pin, eliminated relatively rotating between lock core and lock body, effectively prevented from carrying out technology unlocking with instruments such as hooks, improved theftproof performance.
technical scheme of the present invention is: a kind of tapered end comprises lock body and lock core, lock core is provided with key chamber, blade and leaf spring are installed on lock core, blade passes key chamber and its two ends are corresponding with the groove on the lock body inwall respectively, leaf spring has the trend that blade moves to the lock body direction that promotes, blade is provided with the rectangular central aperture that is complementary with key, centre bore one sidewall of blade is provided with the boss corresponding with tartar on the key, the inner sidewall of lock core and lock body radially is provided with a manhole that runs through lock body and lock core, manhole communicates with key chamber and parallels with the direction of motion of blade, the anti-pellet of dialling is installed in manhole successively, tack pellet and spring, be provided with ladder in the manhole of lock core and limit the anti-pellet of dialling, tack pellet and manhole matched in clearance, spring is by the shutoff of sealing up a door that is embedded on lock body, be provided with and the anti-suitable bellmouth of pellet of dialling with the front end side wall of the suitable key of lock core, when key inserts lock core fully, anti-end of dialling pellet is positioned at the bellmouth of key, just make the anti-pellet of dialling be positioned at lock core fully, the tack pellet is positioned at lock body fully simultaneously.
The outer face of described lock core is provided with anti-drilling sheet and capping, and anti-drilling sheet adopts hardness higher than the material of common drill bit, and anti-drilling sheet and capping are provided with the through hole corresponding with the lock core centre bore.
Described anti-drilling sheet is embedded on lock core, and capping is coated on the edge of lock core by the fin at its edge.
Described lock body is provided with pin hole, is fixed with pin in described pin hole, and described pin hole and manhole have same shaft centre line, and this shaft centre line is perpendicular to the lock body shaft centre line; The outer wall of the lock core at corresponding pin hole place is provided with the certain angle annular groove, and the inserting end of pin is positioned at annular groove.
Described blade be 10 and in lock core both sides to inserting, lock core is provided with 5 jacks that penetrate, described jack be " protruding " shape, the width of blade of lock core both sides is different, the blade that the blade of a side and opposite side are adjacent is in one group of same jack of insertion.
Boss on described blade is located at the same side.
The described anti-pellet end of dialling be taper shape or spherical.
The present invention has following beneficial effect: owing to taking such scheme, when key is extracted, under the effect of spring, the anti-pellet of dialling is pushed in lock core, the tack pellet locks lock body and lock core between lock body and lock core, tack pellet and manhole matched in clearance, make between lock body and lock core and can not relatively rotate, when utilizing the tool technique such as hook to unblank, blade need to be pushed aside and just can touch the anti-pellet of dialling, as push blade aside and just need to first push the anti-pellet of dialling aside, make between lock body and lock core to produce relative rotation.Therefore, the anti-pellet of dialling can prevent effectively that with the tack pellet lock core from rotating relative to lock body, avoids using the instrument such as hook to carry out technology unlocking, has improved theftproof performance.
