Description

Structure improved anti-theft device for automotive number plate

Technical field

The utility model relates to a kind of anti-theft device for automotive number plate, is the improvement to existing anti-theft device for automotive number plate structure, belongs to automotive number plate the attachment technique field of using is installed.

Background technology

Along with The development in society and economy, the remarkable improvement of living standards of the people, various types of vehicles grows with each passing day, yet it is increasing to be accompanied by the stolen incident of number plate (licence plate), stolen number plate is installed on " illegal vehicle " that people are referred to as to call with mainly being grafted flowers on a tree, steal the beams and change the pillars, causes factor leading to social instability for traffic security administration, social stability.Usurped in case nourish the illegal person of evil thought as the number plate of departments such as public security, People's Armed Police, army, its social danger is then bigger.In view of this, a kind of name is called the patent application of " fixedly licence plate use anti-joyride device " for CN2594090Y discloses for Chinese patent Granted publication number, it comprises buckle closure, annular fixed seat, respectively be processed with the jump ring groove at the inwall of buckle closure with the outer wall of annular fixed seat, snap onto in the jump ring groove by jump ring buckle closure is fixed on the annular fixed seat, promptly the annular fixed seat envelope is protected by buckle closure, the person of having an ulterior motive just is difficult to and will be used for fixing removals such as the connecting element of annular fixed seat such as bolt, has a positive strick precaution meaning for preventing that number plate of vehicle is stolen.But, use through in the past few years proves, still there is following shortcoming in this kind structure: the one, and adopt jump ring that buckle closure and the fixed form that annular fixed seat is fixed can have been given play to desirable fixed effect in a short time, but the time cause jump ring owing to the factor of getting rusty and so on long afterwards the fixing effect weaken gradually and even disappear, thereby buckle closure is come off from annular fixed seat, do not have due antitheft effect; The 2nd, earlier jump ring is placed the jump ring groove on the outer wall of annular fixed seat when mounted, after treating that connecting element is taken annular fixed seat number plate and is fixed on the vehicle on the default number plate seat, again buckle closure lid is fitted on the annular fixed seat, jump ring is protruded in the jump ring groove on the inwall that is partially embedded into buckle closure of (leaning out) the jump ring groove on annular fixed seat.But, in the installation exercise process of reality, often exist jump ring and be not embedded into probability in the jump ring groove on the buckle closure exactly, although probability is very low, for concrete car owner, in case meet and then be that a hundred per cent is stolen.Especially,, can cause the buckle closure arch camber so, undermine buckle closure by hollowing if jump ring can not enter in the jump ring groove on the buckle closure exactly; The 3rd, cost height and difficulty of processing are big, and be for example harsh to the processing request that processes cooresponding jump ring groove on buckle closure, the annular fixed seat, and the weight of jump ring groove is difficult to hold.

And for example, a kind of name is called the patent application of " Motor Vehicle license plates theft prevention entomolgist device " for CN200940628Y discloses for Chinese patent Granted publication number, it comprises bullet pad, plain cushion, screw, characteristics are to adopt bullet pad, plain cushion, screw to penetrate the screw cover successively, the screw cover is installed in the lid, and jump ring is arranged in the screw cover draw-in groove.This patent publication us not only amount of parts is many, and owing to adopted jump ring, thereby have the existing problem of above-mentioned last patent documentation equally.

And, Chinese patent Granted publication number for CN201165217Y discloses a kind of name be called " anti-theft device for automotive number plate and install this anti-joyride device used compel solid device " patent application, it is few that it has a component number, simple in structure, and the effective advantage of overall co-ordination between buckle closure (claiming to seal cap in the patent) and the annular fixed seat, but the problem that it exists is: when mounted, also need outfit in addition to compel solid device, complex operation not only, and changed use cost greatly.

Again, the applicant has applied for again that on December 29th, 2008 a kind of name is called " anti-theft device for automotive number plate of structural development ", its number of patent application is 200810242564.0, it is to realize theft-proof by the scarf of the draw-in groove on elastic pinch plate on the buckle closure and the annular fixed seat outer wall, the defective of its existence is: the draw-in groove on the annular fixed seat outer wall need pass through machined into, production efficiency is low, be not suitable for industrialized mass, and inconvenient operation, in the course of processing, there is the smear metal particle to generate, the consumptive material power consumption, the productive costs height.

Summary of the invention

Task of the present utility model is to provide that a kind of simple in structure, pick-proof excellent performance, cost are low, the structure improved anti-theft device for automotive number plate of the high and suitable industrialized mass production of production efficiency.

Task of the present utility model is finished like this, a kind of structure improved anti-theft device for automotive number plate, it comprises buckle closure, screw pick-proof permanent seat and pick-proof pad, the centre of described buckle closure has the chamber of lid, be arranged at intervals with cavity on the chamber wall in described lid chamber, is extruded with a flange to the lid cavity direction in each cavity, the bottom in described lid chamber is expanded and is established and be formed with pick-proof pad chamber; The centre of described screw pick-proof permanent seat has the seat chamber that is used to hold screw, the bottom of screw pick-proof permanent seat offers first screw hole, the upper end of screw pick-proof permanent seat is formed with to turn over along the outside turnover of wall body buckles the limit, the outer rim of turning over the button limit constitutes the embedding limit, screw pick-proof permanent seat places the lid chamber of buckle closure, and the flange on the buckle closure is embedded below the embedding limit of screw pick-proof permanent seat, and the embedding limit embeds in the cavity; Described pick-proof pad places the pick-proof pad chamber of buckle closure, offers second screw hole on the pick-proof pad.

Buckle closure described in the utility model is that punch die is shaped.

Flange described in the utility model is to be formed by the mode of the chamber wall that covers the chamber by punching press.

Screw pick-proof permanent seat described in the utility model is that punch die is shaped.

Described in the utility model turning over when button limit and embedding limit are shaped with screw pick-proof permanent seat forms on the screw pick-proof permanent seat integratedly.

The position of second screw hole on the pick-proof pad described in the utility model is corresponding with the position of first screw hole of described annular fixed seat bottom.

The utility model is because after adopting said structure, one of advantage that has has been saved the jump ring in the prior art, makes structure more become simple; Two of advantage because buckle closure and screw pick-proof permanent seat all adopt blanked part, need not the lathe groove milling, so the production efficiency height, can adapt to industrialized mass production, and easy to operate, steady quality, and interchangeability is good, but while material-saving, energy-conservation reduces production costs; Three of advantage, owing to adopt blanked part, strength and stiffness are all higher, make buckle closure more firm with combining of screw pick-proof permanent seat; Four of advantage the utlity model has more excellent pick-proof performance by setting up the pick-proof pad in the bottom of buckle closure, making.
