Description
Technical field
The utility model relates to the vehicle body fittings field that prevents or indicate use without approval or Theft-proof for vehicle to use, and is specially a kind of anti-unlocking apparatus that rotates by force with pilfer band.
Background technology
Automobile burglar is important problem in the automobile use, also is an important indicator of vehicle safety performance.Automobile burglar relies on lockset to realize usually, only when and the key insertion that is complementary of lock core after can open lock.But present automotive lock when with foreign matter or when not being complementary key, thereby still exists by force the rotation lock mandrel to open the possibility of lockset, thereby makes shielded automobile also be in unsafe state.
Summary of the invention
In order to overcome the defective of prior art, a kind of safe and reliable automobile burglar accessory is provided, the utility model discloses a kind of anti-unlocking apparatus that rotates by force with pilfer band.
The utility model reaches goal of the invention by following technical solution:
A kind of anti-unlocking apparatus that rotates by force with pilfer band, comprise lock core, leaf spring, blade, sleeve and shell, the tubular that connects before and after sleeve and shell all are, the inwall of sleeve has square hole and chute, be installed with lock core in the sleeve, the front end of lock core is a keyhole, the lock core side has vane hole, one end of blade is embedded in the vane hole, the other end of blade is pressed by leaf spring and is embedded in the square hole of sleeve tube wall, it is characterized in that: also comprise stage clip, pilfer band, contiguous block, torsion spring and rocking arm, the rear end of sleeve has groove, and lock core inserts sleeve successively, in pilfer band and the contiguous block, pilfer band be embedded in the corresponding chute of outer casing bottom by stage clip top and the groove of the rear end of sleeve in, the inwall of shell has chute, the sleeve that inside is embedded with lock core and pilfer band is inserted in the shell, and pilfer band also embeds in the corresponding chute in outer casing inner wall bottom, and there are two key shape boss the lock core rear end, key shape boss embeds in the contiguous block chute, and contiguous block is fixedlyed connected with rocking arm by torsion spring.
The anti-of described band pilfer band rotated unlocking apparatus by force, it is characterized in that: all form matched in clearance between sleeve and the shell and between lock core and the sleeve.
When the utility model used, when lockset was closure state, the bullet under the effect of leaf spring of the blade in the lock core vane hole was embedded in the square hole of sleeve, in relative fixed and can't producing relative rotation between lock core and the sleeve under the interconnect function of blade.If this moment is rotational lock core by force, sleeve just can only follow lock core to rotate together, and the pilfer band that is enclosed within the lock core rear end can only be along being in axial sliding in the chute of shell, thereby pushed up the pilfer band that is embedded in sleeve rear end groove and the outer casing inner wall chute skids off outer casing inner wall along outer casing inner wall chute slip disengaging lock core chute with regard to making by stage clip like this, thereby pilfer band is done the axially movable while and is also promoted have endwisely slipping of two key shape boss to break away from lock core along the lock core rear end at its contiguous block on one side, the fixedly connected rocking arm of contiguous block has also broken away from lock core control like this, therefore, lock core can only self dally and not drive the rocking arm rotation, this moment, lockset was not opened all the time, thereby played antitheft effect.
When normally opening lockset; At first insert the key that is complementary with lockset in the keyhole of lock core front end and rotate, blade in the lock core is after the key that is complementary inserts, blade just is compressed in the lock core, just clog-free rotation in sleeve of lock core, lock core can't drive the sleeve rotation like this, and be embedded in the outer casing inner wall chute by stage clip top and the pilfer band of sleeve rear end groove also can not be in axial sliding, the contiguous block that pilfer band can't promote on the lock core breaks away from lock core, like this, contiguous block is axial connection of two key shape boss by chute and lock core rear end still, and driven together in the rotation of lock core and to rotate, and then drive the rocking arm rotation to open lockset.
The beneficial effects of the utility model are: simple in structure, safe and reliable, and good anti-theft effect.

The specific embodiment
Below further specify the utility model by specific embodiment.
Embodiment 1
A kind of anti-unlocking apparatus that rotates by force with pilfer band, comprise lock core 2, leaf spring 3, blade 4, sleeve 5 and shell 9, the tubular that connects before and after sleeve 5 and shell 9 all are, the inwall of sleeve 5 has square hole and chute, be installed with lock core 2 in the sleeve 5, the front end of lock core 2 is keyholes, lock core 2 sides have vane hole, one end of blade 4 is embedded in the vane hole, the other end of blade 4 is pressed by leaf spring 3 and is embedded in the square hole of sleeve 5 tube walls, it is characterized in that: also comprise stage clip 6, pilfer band 7, contiguous block 8, torsion spring 10 and rocking arm 11, the rear end of sleeve 5 has groove, lock core 2 inserts sleeve 5 successively, in pilfer band 7 and the contiguous block 8, pilfer band 7 be embedded in the corresponding chute in shell 9 bottoms by stage clip 6 top and the groove of the rear end of sleeve 5 in, the inwall of shell 9 has chute, the sleeve 5 that inside is embedded with lock core 2 and pilfer band 7 is inserted in the shell 9, pilfer band 7 also embeds in the corresponding chute in shell 9 inwalls bottom, there are two key shape boss lock core 2 rear ends, key shape boss embeds in contiguous block 8 chutes, and contiguous block 8 is fixedlyed connected with rocking arm 11 by torsion spring 10.
For use more convenient safer for the purpose of, can all form matched in clearance between sleeve 5 and the shell 9 and between lock core 2 and the sleeve 5.
When present embodiment used, when lockset was closure state, the bullet under the effect of leaf spring of the blade in the lock core vane hole was embedded in the square hole of sleeve, in relative fixed and can't producing relative rotation between lock core and the sleeve under the interconnect function of blade.If this moment is rotational lock core by force, as shown in Figure 2, sleeve 5 just can only follow lock core 2 to rotate together, and the pilfer band 7 that is enclosed within lock core 2 rear ends can only be along being in axial sliding in the chute of shell 9, thereby be embedded in the chute that skids off shell 9 inwalls in the shell 9 inwall chutes with the pilfer band 7 of sleeve 5 rear end grooves along shell 9 inwall chutes slip disengaging lock core 2 with regard to making by stage clip 6 tops like this, thereby pilfer band 7 is done the axially movable while and is also promoted to break away from lock core 2 at its contiguous block 8 on one side along the slip of the axial slide on the lock core 2, contiguous block 8 fixedly connected rocking arms 11 have also broken away from lock core 2 like this, therefore, lock core 2 can only self dally and not drive rocking arm 11 rotations, this moment, lockset was not opened all the time, thereby played antitheft effect.
When normally opening lockset, at first insert the key 1 that is complementary with lockset in the keyhole of lock core 2 front ends and rotate, as shown in Figure 3 and Figure 4, blade 4 in the lock core 2 is after the key 1 that is complementary inserts, blade 4 just is compressed in the lock core 2, just clog-free rotation in sleeve 5 of lock core 2, lock core 2 can't drive sleeve 5 rotations like this, and be embedded in the shell 9 inwall chutes by stage clip 6 top and the pilfer band 7 of sleeve 5 rear end grooves also can not be in axial sliding, the contiguous block 8 that pilfer band 7 can't promote on the lock core 2 breaks away from lock core 2, like this, contiguous block 8 still passes through chute
ProjectionWith lock core 2 rear ends the axial of two key shape boss arranged
ChuteConnect, and driven rotation together, and then drive rocking arm 11 rotations to open lockset in the rotation of lock core 2.
