Description

Two spoon of two core anti-theft vehicle lock

Technical field

The utility model relates to a kind of lock, particularly a kind of two spoon of two core anti-theft vehicle lock with double insurance function.

Background technology

Present lock is single spoon of single core, and this lock relatively simple for structure can be opened with a key, and for experienced stealer, the lock of opening a single spoon of single core only needs the time of a few minutes, and therefore, the anti-theft feature of present lock is perfect not enough.

The utility model content

The purpose of this utility model is that two keys of a kind of needs that design at present lock anti-theft feature difference are opened two spoon of two core anti-theft vehicle lock just can opening simultaneously.

The purpose of this utility model realizes as follows: two spoon of two core anti-theft vehicle lock described in the utility model is made up of snap close, lock core base and key; Snap close is one " U " shape structure, and " U " shape two ends respectively are provided with two dops, and dop is provided with draw-in groove; The lock core base is a rectangular structure, respectively is provided with the dop hole at four angles, and four dops of snap close can be inserted in four dop holes of lock core base, and two lock cores are installed in lock core base central authorities side by side; The bottom, dop hole of lock core base is equipped with the snap close return spring, lock core base inside is provided with four lock pin grooves and communicates with four dop holes respectively, four lock pins are embedded in respectively in four lock pin grooves, one end of lock pin is insinuated into dop hole central authorities, the other end of lock pin is provided with an elongated hole, the lock pin return spring is installed in the elongated hole, and an end of steady pin inserts in the elongated hole of lock pin, and the other end of steady pin is connected with the lower end of lock core; Key has two, links to each other by hairspring, and in the keyhole of key insertion lock core and after the rotation, lock pin can slide to lock core base central authorities, and two keys rotate simultaneously, and snap close just can withdraw from from the dop hole of lock core base.

Described two keys, the keyboard broad of a key wherein, the keyboard of another key is narrower, insert keyhole after two keyboards overlap mutually, another key also rotates thereupon when rotate a key.

Good effect of the present utility model is: the utility model is broken the traditional concept of " opening different locks with different keys ", but the lock core of two self-returns of employing side by side, two keys unite two into one, two lock cores are controlled the lock pin on both sides respectively, must open two lock cores simultaneously could open lock, if remove to open another lock core again after opening a lock core separately, the so previous lock core meeting self-return of having opened, the structure of this " two spoon of two core " has increased the difficulty that stealer is unblanked greatly, has improved antitheft ability; In order to strengthen anti-theft effect, structure relative complex of the present utility model, but the design of the special construction of double key can make the user only with forefinger push away revolve a key can open, also more convenient than the use of common lock.
