Abstract
The utility model relates to a lock cylinder insurance mechanism comprising a lock cylinder shaft jacket, a lock cylinder shaft and a drive block. The lock cylinder shaft is sleeved in the lock cylinder shaft jacket, fixed in the radial direction and matched with the lock cylinder shaft jacket in a rotating manner; locking pins capable of sliding in the radial direction are arranged on the two sides in the lock cylinder shaft, and extension parts are arranged at the front ends of the lock pins and are matched with grooves formed on the drive block; a locking seat, a front locking block and a rear locking block are sequentially arranged between the lock cylinder shaft and the transmission block; a connection block is arranged at the front end surface of the locking seat and is connected with a connection groove formed at the end part of the lock cylinder shaft; a triangular bulge is arranged on the peripheral edge of the rear end surface of the locking seat, and a central shaft is arranged in the middle of the locking seat; the front locking block and the rear locking block are crossed with each other and hinged on the central shaft; and a compression spring is arranged between one ends of the front and rear locking blocks and the opposite surface of the triangular bulge, and a limit surface is formed on the other ends of the front and rear locking blocks. The lock cylinder insurance mechanism greatly improves the anti-theft performance of a lock cylinder and has the advantages of being simple in structure, low in failure rate and strong in reliability.
Description
Technical field
The utility model 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 utility model provides a kind of lock core insurance institution, and the theftproof performance of this lock core insurance institution is strong, reliability is high.
The utility model solves the technical scheme that its technical problem adopted: 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 utility model 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.

Fig. 2 is the assembly structure sketch map of the utility model.
Fig. 3 is the C-C sectional view of Fig. 2.
Fig. 4 is the structural representation of lock-out state lower extension and preceding clamping block, back clamping block.
Fig. 5 is the structural representation of unlocking condition lower extension and preceding clamping block, back clamping block.
The specific embodiment
As shown in the figure, the utility model comprises lock core shaft's overcoat 1, lock core shaft 2 and drive block 3, and 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 utility model.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 the utility model lock core insurance institution; Be not that design and scope to utility model limits; Under the prerequisite that does not break away from the utility model scheme; Various external form modification and improvement that those skilled in the art make the technical scheme of the utility model all should fall into the protection domain of the utility model lock core insurance institution.
