Description

Antitheft sylinder
Technical field
The utility model is related to a kind of lock, especially a kind of spring lock applied on safe-guard door lock.
Background technology
Currently, electronic password lock be one kind by Password Input come control circuit or chip operation (access control system Unite), to the closure of control machinery switch, the electronic product completed unlocking, be latched task.Wider electronic cipher is applied now Lock is to pass through what is be programmed to using chip as core.Electronic lock has anti-theft alarm function in field of prevention of a safety technology Electronic password lock replaces traditional mechanical code lock, the shortcomings that overcoming few mechanical code lock number of password, poor safety performance, Make no matter coded lock technically or in performance all greatly improves a step.
But electronic cipher is latched in certain emergency situations, such as out of power or failure of chip lead to the feelings for not opening lock At this moment condition just needs mechanical lock to assist, generally all can lock installation spring lock, the volume one of existing spring lock in electronic cipher As it is larger, i.e. the thickness of lock body is thicker.
Traditional spring lock is mainly made of lock housing, rotatable lock core and several row's pellets, is adopted with most commonly seen For the theftproof lock of cylinder-shaped marble, it is inserted into the pellet often arranged after correct key and is at correct position, that is, descend pellet Just at lock core, upper pellet just at lock housing so that lock housing can rotate to unlock, and extract key or inserting error Key, then pellet can be between lock housing and lock core so that lock core is from rotating, the shortcomings that traditional spring lock is can be by Tool applies torsion to lock core makes pellet bear transverse shear appropriate, is dialled using power sense examination, one by one by upper pellet and lower pellet point From in the hole of lock housing and lock core, to realize that technology is opened, anti-theft performance is very poor, not enough securely and reliably.
Invention content
In order to overcome the deficiencies of the prior art, the utility model provides, and a kind of anti-theft performance is good, small antitheft bullet Son lock.
To achieve the goals above, the technical solution adopted in the utility model is:A kind of antitheft sylinder, including lock housing, Rotatable lock core and several pellets are provided with the keyhole being axially distributed along it on the lock core, are set on the lock core It is equipped with marble hole, marble hole constitutes marble hole unit along the axially spaced-apart distribution of lock core, and marble hole cell distribution is in keyhole Both sides, each marble hole are connected to setting with keyhole by communicating passage, spring and institute are both provided in each marble hole The pellet stated, pellet is in a strip shape, and for pellet towards pillar is provided on the side of keyhole, which is pierced by bullet by communicating passage Sub-aperture is placed in keyhole, and pellet is constituted with marble hole is oriented to sliding setting, and each pillar in each marble hole unit can be in Alignment is arranged, and is provided with along its axially extending bar-shaped trough on the periphery of the lock core, bar-shaped trough is connected to setting, bullet with marble hole The setting of corresponding with the pillar other side is fluted on son, and the groove on each pellet is movable to and bar shaped with the movement of pellet Slot is aligned, and is provided with the compression bar that can be inserted into the groove in bar-shaped trough, being provided between compression bar and bar-shaped trough makes compression bar and bar-shaped trough The compressed spring of expansion fit is constituted, the limiting slot for constituting clamping limit cooperation with compression bar is provided on the inner wall of the lock housing.
In above-mentioned technical proposal, each marble hole unit is by several along the marble hole group of the axially spaced-apart distribution of lock core Be two at, preferred marble hole unit, be located at the both sides of keyhole, when being inserted into key toward keyhole in, pillar and Track on the key corresponds to, and with Orbit revolutionary on the key, that is, drives pellet along marble hole guiding movement, make same pellet The groove on pellet on the unit of hole is in a straight line, i.e., each groove, which is aligned with bar-shaped trough, to be connected to, after rotating key, The relative rotation trend of lock core and lock housing to compression bar apply shearing force, inside being inserted radially into groove along lock core of compression bar, The outside for making compression bar is flushed with the periphery of lock core, and the clamping limit for releasing compression bar and limiting slot coordinates, and such lock core can be free Compression bar need to be gone to and be aligned with limiting slot when extracting key by rotation, and compression bar stretches out bar-shaped trough under the action of compressed spring, convex It rises on the periphery of lock core, forms clamping limit cooperation with limiting slot, prevent lock core from arbitrarily being rotated, play the role of locking, Pellet resets again under the action of the spring, so that each pillar on same marble hole unit is located along the same line, existing skill In art, existence position is poor between each pellet, and interval is larger, and operating space is provided to technology unlatching, and in the design, respectively Interval between a pillar is small, and each pillar is located along the same line, and operating space is small, is difficult to realize technology and opens, so Anti-theft performance is more preferable, and the thickness of lock housing is small, more convenient when installation, saves space, simple in structure, service life is long, at low cost.
As the further setting of the utility model, the bar-shaped trough is correspondingly arranged at the both sides of keyhole, two bar-shaped troughs Center line relative to lock core is towards the same side in eccentric setting.
In above-mentioned technical proposal, bar-shaped trough is in eccentric setting, and opposite limiting slot is also set in bias, and eccentric setting can make lock The resistance bigger that core and lock housing relatively rotate, anti-theft effect are more preferable.
As the further setting of the utility model, it is provided with abutting block on the both ends inner wall of the bar-shaped trough, compresses bullet Spring is located at the both ends of bar-shaped trough and is connected on respective abutting block, and the both ends of compression bar are extended outward to form to be adapted to compressed spring Abutment end, compression bar be in T fonts.
In above-mentioned technical proposal, one end of compressed spring, which is connected to, to abut on block, and the other end is connected on abutment end, is abutted End coordinates with abutting block and formed to limit, and it is mating with groove to may pass through bar-shaped trough in the middle part of compression bar, simple in structure, installation side Just.
As the further setting of the utility model, the inner wall of the limiting slot and the inner wall of lock housing connect for arc-shaped transition It connects, the outside of compression bar is arc-shaped.
In above-mentioned technical proposal, arc setting can facilitate lock core to rotate, and reduce frictional force, prolong the service life.
As the further setting of the utility model, it is provided with bulge loop on the periphery of the lock core, the bulge loop and lock housing structure Coordinate at limit, limited post is provided in the keyhole.
In above-mentioned technical proposal, the setting of bulge loop avoids locking just in order to limit lock core and the relative position in lock housing axial direction Lock housing is stretched into core transition, and the setting of limited post is to avoid damage to structure, or can not rotation lock in order to which limit key stretches into degree Core causes key to be broken, simple in structure, easy to process.
The utility model is further described below in conjunction with the accompanying drawings.
