Abstract

The present invention relates to an automotive tyre anti-theft screw for preventing automotive tyre from being stolen. It includes screw and nut. It is characterized by that on the original screw a lengthened part is connected, the diameter of said lengthened part is smaller than that of original screw, on the lengthened part is cipher lock is set, namely, on the periphery of said lengthened part at least one projection is set; besides, it has fastening ring which can be matched with said projection, the outer diameter of said fastening ring is greater than that of the screw, on the periphery the digital codes or letters are marked. Said invention also provides the working principle of said anti-theft screw for automotive screw, its operation and application method.

Description

Antitheft bolt for vehicle tyre

Technical field

The present invention relates to the wheel technical field of general vehicle, especially relate to the anti-theft device of wheel.

Background of invention

Along with the high speed development of car industry, automobile rolls up, and a lot of automobiles usually berth in the open because of no garage, and the tire robbery accident happens occasionally; Stolen for preventing automobile tire, China's utility model patent discloses a kind of " antitheft bolt for vehicle tyre nut ", notification number: CN2265916Y, it is in the end of hex head bolt or nut circular hole to be set, a plurality of annular grooves are arranged on the inwall of hole, a page sheet lock pin is housed in the circular hole, a plurality of pages of sheets of lock core and annular groove corresponding matching, the case that hex head bolt or nut are equipped with drum shape outward and are slidingly matched, concave station cooperates with lock core upper end boss in the case outer end; Can prevent also on the screw that bolt from opening though this structure is located at, on nut perforate infeasible, and will undermine the intensity of nut, and lock core will be installed, wear key fully, all be pretty troublesome thing.

Summary of the invention

The objective of the invention is in order to overcome above-mentioned the deficiencies in the prior art, a kind of original intensity of bolt that neither undermines be provided, again need be not fully with the antitheft bolt for vehicle tyre of key.

For achieving the above object, technological scheme of the present invention is such: a kind of antitheft bolt for vehicle tyre comprises screw and nut, it is characterized in that on former screw, connecing the growth section, be about to the screw front end and increase, the diameter that increases section is littler than screw, on this growth section periphery a projection is set at least; Other has the clasp that is complementary with this projection number, the external diameter of this clasp is greater than screw diameter, be marked with number or letter in periphery, constitute password by this number and letter, its endoporus matches with a growth section diameter, can relatively rotate and move with the growth section, and have the groove that links to each other with endoporus projection scarce and the growth section to match; In the clasp periphery one case is arranged, this case external diameter is greater than the screwhole diameter of bolt, and distance less than the hexagon nut opposite flank, so that socket wrench can pass through this case external diameter, its internal diameter matches with the external diameter of clasp, have a slotted eye at case upper edge screw axial, this slotted eye is exposed with the part periphery of clasp, can stir clasp and rotate or translation.

During use, each tire only need with the case of interior dress clasp, cover the growth section of screw with this anti-theft bolt, and clasp is in place at once on the growth section; In the time of need opening, can stir clasp it is gone to the digital place of setting, the interior hole slot of clasp lacks the projection passing that aligning increases section, and the clasp connection is unloaded from the growth section together with case, bolt is opened again.

Owing to adopted technique scheme, a kind of antitheft bolt for vehicle tyre of the present invention compared with prior art, has simple in structurely, easy for installation, does not undermine the original intensity of bolt, only need remember password, not indispensable band key, and good anti-theft effect is suitable for popularization.

Embodiment

Embodiment 1

By Fig. 1-shown in Figure 4, a kind of antitheft bolt for vehicle tyre of the present invention comprises screw 1 and nut 2, it is characterized in that connecing on former screw increasing section 3, is about to the screw front end and increases, and the diameter that increases section is littler than screw, in this growths section cipher lock is set; Said cipher lock is that the periphery that increases section is provided with two projectioies 301; Other has the clasp 4 that is complementary with this projection number, the external diameter of this clasp 4 is greater than screw diameter, be marked with number or letter in periphery, constitute password by this number and letter, its endoporus 401 matches with a growth section diameter, can with increase section and relatively rotate and move, and have the groove that links to each other with endoporus 401 to lack 402 to match with the projection 301 of growth section; In clasp 4 peripheries one case 5 is arranged, this case external diameter is greater than the screwhole diameter of bolt, and less than the distance of hexagon nut opposite flank, so that socket wrench can pass through this case external diameter, its internal diameter matches with the external diameter of clasp, and being provided with on an end face of case can be by increasing the hole of section; Have a slotted eye 6 at case upper edge screw axial, this slotted eye 6 is exposed with the part periphery of clasp 4, can stir clasp and rotate or translation.

Embodiment 2

By Fig. 5-shown in Figure 8, be that 4 of two clasps in embodiment 1 are placed an annulus 7, pore radius is greater than increasing the section axle center to protruding end face distance in this annulus; Its external diameter equates with the external diameter of clasp 4; All the other repeat embodiment 1.

In the above-described embodiments, the slotted eye 6 on the said case 5, on one side can extend to the end face of case to case, so that the putting into of clasp;

Slotted eye 6 on the said case 5 also can not extend to the end face of case, earlier clasp 4 and annulus 7 is put into the case cylindrical shell during assembling, and is again that end face is fixing in the welding of seam 501 places;

The groove scarce 503 that the set hole of passing through to increase section comprises and increases the endoporus 502 that the section diameter matches and and link to each other with endoporus 502 and matches with the projection 301 that increases section on said case one end face;

The said projection 301 that is provided with on the section periphery that increases can only be established one, also can establish to three, four more, and number is many more, and the password number is big more, and it is difficult more to open.
