The lock cylinder shaft is sleeved in the lock cylinder shaft jacket, is fixed radially and is in running fit with the lock cylinder shaft jacket, locking pins capable of sliding radially are arranged on two sides in the lock cylinder shaft, an extension portion is arranged at the front end of each locking pin, the extension portions match with grooves arranged on the transmission block, a locking seat, a front locking block and a rear locking block are successively disposed between the lock cylinder shaft and the transmission block, a connecting block is disposed on the front end surface of the locking seat and connected with a connecting groove arranged at an end of the lock cylinder shaft, a triangular bump is arranged on the peripheral edge of the rear end surface of the locking seat, a center shaft is disposed in the middle of the rear end surface of the locking seat, the front locking block and the rear locking block are crossed and are hinged on the center shaft, pressure springs are disposed between one end of the front locking block and the opposite surface of the triangular bump and between one end of the rear locking block and the opposite surface of the triangular bump, and limiting surfaces are arranged at the other ends of the front locking block and the rear locking block. The safety unit greatly improves the antitheft performance of the lock cylinder, and has the advantages of simple structure, low fault rate and high reliability.
Description
Technical field
The present invention relates to a kind of lock core insurance institution.
Background technology
In the existing lock core mechanism that opens and closes through both sides lockweight control lock core, generally all do not have design insurance mechanism, have the only possibility that correctly can unblank of the close tooth of a side of key, thus theftproof performance a little less than.
Summary of the invention
In order to overcome the above-mentioned defect problem of prior art, the present invention provides a kind of lock core insurance institution, and the theftproof performance of this lock core insurance institution is strong, reliability is high.
The technical solution adopted for the present invention to solve the technical problems is: comprise lock core shaft's overcoat, lock core shaft and drive block; Lock core shaft is socketed in lock core shaft's outer casing internal diameter and is rotatably assorted to fixing and formation; But both sides are provided with the lockweight of radial slippage in the lock core shaft; The front end of lockweight has extension, and the groove of offering on extension and the drive block matches, and between lock core shaft and drive block, sets gradually locking seat, preceding clamping block and back clamping block; The front end face of locking seat is provided with and connects piece; Connect piece and link to each other with the access slot that the lock core shaft end is offered, the circumferential edges of locking base rear end face is provided with that triangle is protruding, the middle part is provided with central axis, and preceding clamping block is arranged in a crossed manner and be hinged on the central axis with the back clamping block; Before stage clip is set between the protruding opposite face of an end and the triangle of clamping block and back clamping block, preceding clamping block is provided with confined planes with the back other end of clamping block.
On the locking seat body, offer the linked slot that is complementary with extension.
The present invention is through above-mentioned concrete design; That has stopped to unblank under the existing existing key of the lock core mechanism correct situation of the close tooth of a side through the switching of both sides lockweight control lock core maybe; Improved the theftproof performance of lock core greatly, have simple in structure, fault rate is low, the advantage of good reliability.

The specific embodiment
As shown in the figure, the present invention includes lock core shaft's overcoat 1, lock core shaft 2 and drive block 3, lock core shaft 2 is socketed in radially to fix and form in lock core shaft's overcoat 1 and is rotatably assorted, and lock core shaft 2 is radially fixing through jump ring 21 with lock core shaft's overcoat 1 in the present invention.But both sides are provided with the lockweight 4 of radial slippage in the lock core shaft 2, and the structure of lockweight 4 both sides radial slippage lock core shaft 2 in can be that illustrated special-shaped pellet shot from a slingshot 17, plush copper 18, cunning push away the structure that groove 19 matches with lockweight 4; Also can be that not shown in line pellet shot from a slingshot directly matches with lockweight 4; Or other structure, no matter adopt which kind of structure, as long as can make lockweight 4 both sides in lock core shaft 2 produce radial slippage.The front end of lockweight 4 has extension 5; The groove of offering on extension 5 and the drive block 36 matches; Between lock core shaft 2 and drive block 3, set gradually locking seat 7, preceding clamping block 8 and back clamping block 9; The front end face of locking seat 7 is provided with and connects piece 10, connects piece 10 and links to each other with the access slot 11 that lock core shaft 2 ends are offered, and the circumferential edges of locking 5 rear end face is provided with that triangle is protruding 13, the middle part is provided with central axis 14; Before clamping block 8 and back clamping block 9 arranged in a crossed manner and be hinged on the central axis 14; Between one end of preceding clamping block 8 and back clamping block 9 and the opposite face of triangle protruding 13 stage clip 15 is set, preceding clamping block 8 is provided with confined planes 16 with the other end of back clamping block 9, on locking 7 body, offers the linked slot 12 that is complementary with extension 5.Under user mode; Close tooth is correct even key has a side, and making lockweight 4 and the extension 5 thereof of a side can under the effect of back-moving spring 20, move and promote corresponding clamping block such as preceding clamping block 8 hinges changes and open, but because back clamping block 9 keeps motionless; In the moving process of above-mentioned extension 5, will certainly bump confined planes 16 so to back clamping block 9; Above-mentioned extension 5 can not continue to move into the groove 6 on the drive block 3, and drive block 3 can not rotate, and lock still can not be opened.Above-described embodiment describes the preferred implementation of lock core of the present invention insurance institution; Be not that the design and the scope of inventing limited; Under the prerequisite that does not break away from the present invention program; Various external form modification and improvement that those skilled in the art make technical scheme of the present invention all should fall into the protection domain of lock core of the present invention insurance institution.
