Description
Technical field
The present invention is the improvement to anti-theft screw structure.
Prior art
A kind of existing anti-theft screw, can prevent from being dismantled using any extracting tool, effectively serve anti-theft function.Its structure is that anti-theft screw is made up of two parts；Top is hexagonal part, and bottom is screw element；Screw element top arranges spring eye, and in the hole is divided into many ribs hole equipped with spring, the top of spring eye, and its section is many prismatics；The pitch-row in many ribs hole is more than the diameter of spring eye；Spring eye and many ribs hole coaxial line；Hexagonal part top is provided with lockhole, is provided with lock in lockhole；With lockhole insertion rib hole more than, identical with many ribs hole of screw element；The length in lockhole and many ribs hole is more than the length of lock core；Many ribs block is matched with many ribs hole shape, and many ribs block moves up and down in many ribs in the hole；The structure of described lock is made up of with lock shell lock cylinder；One skewed slot is provided with outer wall of lock core, lock inside the shell fixes a lateral pin；Lateral pin end is stretched out in skewed slot, and lateral pin is slidably connected with skewed slot.While lock core rotates, because lateral pin is motionless, skewed slot can only be made to slide along lateral pin.
The anti-theft screw of this structure, its shortcoming is to use, and after key band movable lock core ratates 90 degrees, the skewed slot on lock core moves along the lateral pin on lock shell；Because fluting is can not open oversize on lock core, result in that the lock core stroke that stretches is too short, lock core drive many ribs block enter many ribs in the hole depth limited, cause many ribs block easily to skid in many ribs in the hole, affect using effect.In addition, screw element top setting spring eye and, complex production process complex built with the structure of spring, production cost height.
Content of the invention
The purpose of the present invention is, the shortcoming overcoming above-mentioned prior art to exist, and provides a kind of improved anti-theft screw.
A kind of anti-theft screw is it is characterised in that be made up of two parts；Top is connector, and bottom is screw element；Connector is rotated with screw element and is connected；
The top of screw element is set up separately and is set to interior many ribs hole；
It is provided with lock, lock is made up of with lock core lock shell in connector；Lock core is rotated with lock shell and is connected；Connector bottom arranges the many ribs hole insertion on many ribs hole, with screw element；The bottom of lock core is a threaded rod, and threaded rod is located at many ribs in the hole；There is a band female many ribs block, threaded with threaded rod；Many ribs block moves up and down in many ribs in the hole；
Many ribs hole length summation on screw element and connector is more than the length of many ribs block；Many ribs hole of lock core and connector, many ribs hole coaxial line of screw element；Many ribs hole section is many prismatics；Many ribs block is matched with many ribs hole shape；
Lock shell is fixedly connected with connector.
Operation principle of the present invention is, when needing to dismantle anti-theft screw, insert a key into lock core hole, rotate lock core a few, rotated by the threaded rod of lock core, drive many ribs block to bottom offset, many ribs block enters into many ribs in the hole of screw element, now, screw element is integrally formed with connector, using universal dismounting tool rotating connector, you can dismounting screw.See accompanying drawing 10.
When needing antitheft, key is back rotated a few, rotating by the threaded rod of lock core makes to move reset on many ribs block, many ribs block is departed from screw element, so that connector is separated with screw element；Now, even if using any extracting tool on connector, also cannot dismantle anti-theft screw, because connector is originally in rotation, and screw element is motionless.See accompanying drawing 8.
The present invention not only can prevent from being dismantled using any extracting tool, effectively serves anti-theft function, and structure more advantages of simple.Because many ribs block is helicitic texture, but lock core is made to drive a few 360 degree rotations of threaded rod, many ribs block upper and lower displacement stroke is long, will not be able to skid completely in the many ribs hole on screw element, safe and reliable, is hardly damaged.Present configuration more brief and practical, simple production process, cost substantially reduces.The present invention is not susceptible to fracture in the application, and due to being to move up and down, and the present invention can apply on short and small screw below 12 for the Φ, using more safe and reliable, expands range；Especially apply on the tire of car, be hardly damaged, anti-theft effect becomes apparent from；And with low cost, easily popularize, applied range；Can be applicable to antitheft on tire, be also applicable in antitheft on the camp equipments such as oil field, various pump class, transformator.
