Abstract
The utility model discloses a motor vehicle license plate fastening alarm, which comprises a fastening bolt (3), a lagging (4) and a taper-typed nut (6). The lagging (4) is provided with a cylinder-type groove on which is provided with a copping (1) of interference fit. The copping (1) is made of stainless steel and its head is formed as four feet. On the fastening bolt (3) inside the cylinder-type groove of the lagging (4) is provided with an adjusting gasket (2). The height difference between the sphere of the fastening bolt (3) and the copping (1) is between 0.1 mm to 0.3 mm and the appearance bending surface between the copping (1) and the lagging (4) is transitioning smoothly. After the adaptation of the mentioned structure, the device is unable to throw pulling or prying axial power on the copping (1), thus, the vehicle license plate will not be so easily stolen. In addition, the utility model has the advantages of simple and reasonable structure, convenient installation and utilization, low cost, good anti-theft performance and reliable quality,, etc.
Description
Technical field
The utility model relates to a kind of Motor Vehicle annex, particularly a kind of securing means that prevents that automobile license plate from illegally being dismantled.
Background technique
Along with the development of society and the progress of science and technology, social car owning amount grows with each passing day, and the stolen phenomenon of automobile license plate takes place repeatedly, and is stolen in order to prevent automobile license plate, and people are generally installed the fastening anti-theft device of car plate additional when automobile license plate is installed; But some does not just have anti-theft feature the fastening anti-theft device of existing car plate at all, though some possesses anti-theft feature, and the production technology more complicated, component are more in the device, and cost is higher, and the effort of taking a lot of work during installation is difficult in and forms batch or popularization on the market.
The patent No. of bulletin is 02232186.1 " the anti-fastener that unloads of automobile license plate " as State Intellectual Property Office on December 3rd, 2003; This structure is provided with the anti-guard housing of cylindrical groove shape of protection bolt on existing clamping bolt, the inwall of anti-guard housing is a truncated cone, be provided with a boss in its bottom, the protection flap of the body of falling the groove is arranged at anti-guard housing top, the sidewall of protection flap is the truncated cone that matches with the inwall of preventing guard housing and bottom boss, and several openings are arranged on this truncated cone; This structure has played quick detachable, not antitheft purpose really, but processing technology more complicated, cost are higher, have hindered product and have applied on market, and the fact has also proved this point.Today that automobile is popularized in people life day by day, a kind of with low cost, car plate fastener that theftproof performance is good of market in urgent need.
Summary of the invention
In order to overcome the above-mentioned disadvantage that existing automobile license plate securing means exists, the utility model provides a kind of simple and reasonable, installation and the fastening alarm of automobile license plate easy to use, that cost is low, theftproof performance is good.The technological scheme that its technical problem that solves the utility model adopts, it comprises clamping bolt, protecting cover, conical nut, and described protecting cover is provided with cylinder shape groove, and cylinder shape groove is provided with the top cover of interference fit.
Described top cover is made by stainless steel, and the head of top cover is made as four pin.
Be provided with on the clamping bolt in the cylinder shape groove of protecting cover and adjust pad and compression spring.
The sphere of described clamping bolt and the height difference of top cover between 0.1 to 0.3 millimeter, the appearance curved surface rounding off between top cover and the protecting cover.
After adopting said structure, utilize the elasticity tension of four pin of stainless steel top cover and the cylinder shape groove inwall interference fit of protecting cover, making has the above radial force of 300N between top cover and the protecting cover, and the stiction of generation is enough to prevent get loose between top cover and the protecting cover; Protecting cover adopts impact style to make, and the cylinder shape groove of protecting cover does not need gold machining, and internal diameter size is directly guaranteed by mould, and dimensionally stable can guarantee and top cover external diameter magnitude of interference absolute stability; Adjust pad and be mainly used in the sphere of adjustment clamping bolt and the height difference of top cover, prevent that top cover is entered for striking depression by the people when unauthorized theft, allow extraneous instrument extract protecting cover, the effect of playing supporting and preventing to deform because of the stressed top cover in the external world to the top cover application of force; After top cover was pressed into protecting cover, design size guaranteed top cover and protecting cover curved surface rounding off in appearance, can't apply the outer axial force of drawing or prizing to top cover at all, thus reach prevent unloading, antitheft purpose; Have simple and reasonable, installation and easy to use, cost is low, theftproof performance good, advantage such as safe and reliable.
