Description
Technical field
The utility model is the improvement to anti-theft screw structure.
Prior art
Existing a kind of anti-theft screw, can prevent from using any extracting tool to dismantle, effectively serve anti-theft function.Its structure is that anti-theft screw is made up of two-part; Top is hexagonal part, and bottom is threaded piece; Threaded piece top arranges spring eye, and hole is built with spring, and the top of spring eye is divided into many ribs hole, and its cross section is many prismatics; The pitch-row in many ribs hole is greater 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 through rib more than hole, identical with many ribs hole of threaded piece; The length in lockhole and many ribs hole is greater than the length of lock core; Many ribs block and many ribs hole shape match, and many ribs block moves up and down in many ribs hole; The structure of described lock is made up of bullet lock master and lock shell; Outer wall of lock core is provided with a skewed slot, lock shell internal fixtion one lateral pin; Lateral pin end is stretched out and is positioned at skewed slot, and lateral pin and skewed slot are slidably connected.Lock core because lateral pin is motionless, can only make skewed slot slide along lateral pin while rotating.
The anti-theft screw of this structure, its shortcoming is, makes with Time, and after key band movable lock core 90-degree rotation, the skewed slot on lock core moves along the lateral pin on lock shell; Because on lock core, fluting is can not open oversize, result in the lock core stroke that stretches too short, the degree of depth that lock core drives many ribs block to enter in many ribs hole is limited, causes many ribs block easily to skid in many ribs hole, affects using effect.In addition, threaded piece top arranges spring eye and the structure built with spring is comparatively complicated, and complex production process, cost of production is high.
Summary of the invention
The purpose of this utility model is, overcomes the shortcoming that above-mentioned prior art exists, provides a kind of anti-theft screw of improvement.
A kind of anti-theft screw, is characterized in that, be made up of two-part; Top is link, and bottom is threaded piece; Link and threaded piece are rotationally connected;
The upper part of threaded piece is set to interior many ribs hole;
Be provided with lock in link, lock and be made up of lock shell and lock core; Lock core is rotationally connected with lock shell; Link bottom arranges many ribs hole, through with the many ribs hole on threaded piece; The bottom of lock core is a threaded stem, and threaded stem is positioned at many ribs hole; There is the female many ribs block of a band, be threaded with threaded stem; Many ribs block moves up and down in many ribs hole;
Many ribs hole length summation on threaded piece and link is greater than the length of many ribs block; Many ribs hole of lock core and link, many ribs hole coaxial line of threaded piece; Cross section, many ribs hole is many prismatics; Many ribs block and many ribs hole shape match;
Lock shell is fixedly connected with link.
Utility model works principle is, when needs dismounting anti-theft screw, key is inserted lock core hole, rotational lock core a few, rotated by the threaded stem of lock core, drive many ribs block to bottom offset, many ribs block enters in many ribs hole of threaded piece, now, becomes to be integrated with link by threaded piece, use universal dismounting tool rotating connector, i.e. detachable screw.See accompanying drawing 10.
When needing antitheft, key is back rotated a few, rotated by the threaded stem of lock core and make many ribs block moves reset, many ribs block departs from threaded piece, and link is separated with threaded piece; Now, even if use any extracting tool on link, also anti-theft screw cannot be dismantled, because link is just originally in rotation, and threaded piece is motionless.See accompanying drawing 8.
The utility model not only can prevent from using any extracting tool to dismantle, and effectively serves anti-theft function, and structure more advantages of simple.Because many ribs block is worm structure, but make lock core drive threaded stem a few 360 degree rotations, many ribs block upper and lower displacement stroke is long, can enter into the many ribs hole on threaded piece completely, can not skid, safe and reliable, not fragile.The utility model structure more brief and practical, production technology is simple, and cost reduces greatly.The utility model not easily fractures in the application, and owing to being move up and down, the utility model can be applied on the short and small screw of Φ less than 12, uses more safe and reliable, expands using scope; Especially be applied on the tire of sedan car, not fragile, anti-theft effect is more obvious; And with low cost, easily popularize, applied range; Can be applicable on tire antitheft, what also can be applicable on the camp equipments such as oil field, various pump class, transformer is antitheft.
