Description

Be used for the anti-theft device on the licence plate fixed block

Technical field

The utility model relates to a kind of stolen device of license plate that prevents, especially refers to a kind of anti-theft device that is used on the licence plate fixed block.

Background technique

At present, the license plate placing device that China uses generally is directly license plate to be fixed on the car body with anti-theft screw, and its maximum shortcoming is that theftproof performance is poor, is stolen by the thief easily and loses; What also have has a warning device on licence plate, but its complex structure, fabricating cost is high and use also inconvenient.The patent No. is that 01226137.8 Chinese utility model patent has proposed a kind of anti-theft license plate structure for this reason, its structure is characterised in that, it is that a licence plate is laid box in main body, the front has the licence plate form, backboard is provided with the lockhole that cooperates with dead bolt, the centre is the licence plate mounting groove, also has the axis hole that can be rotationally connected with car body in the bottom that licence plate is laid box.Though this structure has certain anti-theft effect, but its shortcoming: at first be, with box license plate frame is got up admittedly, naturally this box to have certain anti-ly anti-ly dig, the intensity of pick-proof, deal is often heavier, and fixedly the screw of box or bolt have the restriction of certain specification, like this when vehicle operating because of the vibration fixedly screw or the bolt of box of wearing and tearing gradually, therefore can hold very much box is come off and lose or damage licence plate, cause the suspension of licence plate very short working life; Next is, certain anti-anti-ly digs because of box will have, the intensity of pick-proof, and deal is often heavier, and it is higher to make its cost of raw material naturally, thereby cause unnecessary economic loss because of the buying expenses height can for the user; Being once more, with box license plate frame being got up admittedly, obviously is to have increased installation procedure one, bothers so install also, and comes the solid licence plate of frame with box, just means that licence plate is installed must box, naturally its project organization is complicated.So above-mentioned structure awaits further to improve.

Summary of the invention

Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of simple in structure, fabricating cost is low, long service life, easy for installation and good anti-theft effect be used for anti-theft device on the licence plate fixed block.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: this is used for the anti-theft device on the licence plate fixed block, include cipher lock and the bolt or the screw that are used for fixing licence plate, it is characterized in that described cipher lock detached type structure and sleeve are fixed together, bottom at sleeve has through hole, one end of described bolt or screw is positioned at sleeve, and its other end stretches out from the through hole of cover tube bottom.

The structure that above-mentioned cipher lock detached type structure and sleeve are fixed together may be selected to be: be provided with the portion of button on the barrel of sleeve, and the described cipher lock and the portion of button are buckled together for cover.

The structure of above-mentioned cipher lock can be preferably and include digital rotating disk, socket cover, spring seat, spring, ratchet dish and lock collar, its middle part, back side of described digital rotating disk is provided with rotating shaft, the end and the lock collar of this rotating shaft are fixed together, in the rotating shaft between digital rotating disk and the lock collar successively rotationally string be with socket cover, spring seat, the ratchet dish, and described socket cover is fixed on the outer peripheral surface of sleeve for cover, and spring seat and socket cover are to fix together mutually, one end of described spring is fixed in the spring seat, and the other end of spring is to be buckled on the ratchet of ratchet dish periphery, and on lock collar and ratchet dish, have breach separately, and on lock collar and ratchet dish opposing side, be provided with separately and can fasten mutually when lock collar is rotated with rotating shaft and drive the small lugs that the ratchet dish rotates, described button portion is arranged on the sleeve wall two not at grade protruding buttons of pivot ear shape; And between described lock collar and ratchet dish, also can be lined with pad, and this pad can have two, and one is compression spring, and another is a conventional pads, and both stack respectively and go here and there and are placed in the rotating shaft.

The structure that the end of above-mentioned rotating shaft and lock collar are fixed together can be preferably: the periphery in roller end is a polygonal, and on lock collar, have trepanning, the polygonal end shape of this trepanning inwall and rotating shaft is suitable, the polygonal end of rotating shaft is fixed with each other for being inserted in the trepanning, and lock collar is locked in the end of rotating shaft by screw and pad at the rotating shaft end face.

Compared with prior art, the utility model is fixed together small-sized cipher lock detached type and sleeve because of adopting, bottom at sleeve has through hole, and an end that is used for fixing bolt on the licence plate or screw stretches out from the through hole of cover tube bottom, the advantage of its structure is, cancelled box, but adopt the turning on the spiral surface of retaining screw that small-sized cipher lock directly is covered in fixing licence plate, licence plate has not only possessed antitheft effect like this, and the deal of cipher lock is very light, can not constitute weight load to the retaining screw of fixing licence plate, so can avoid effectively causing the retaining screw wearing and tearing because of automobile vibration, fundamentally eliminated and the phenomenon that licence plate comes off or loses occurred, thereby prolonged significantly the working life that licence plate is hung; Next is, has cancelled the box of frame-like, and has adopted small-sized cipher lock, has not only saved and makes the raw material of anti-theft product, but also reduced the economic cost that the user buys the anti-theft license plate product directly, effectively, thereby be user's Gospel of taking; Be once more, installation of the present utility model is very convenient, as long as fixedly the screw of licence plate or bolt string are enclosed within the sleeve, then with screw-driver screw or bolt are tightened, cipher lock gets final product on the sleeve upper sleeve cover again, installation process is with that common licence plate is installed is the same, just overlaps to cover cipher lock and get final product behind fixing licence plate, so install very convenient again.Therefore a kind of product very ingenious of the present utility model is worthy of popularization.
