Abstract
The utility model relates to an anti-dismantling bolt and nut assembly, which comprises a bolt and a nut, and is characterized in that an inner hexagonal screw hole which is different form a standard caliber is arranged on the bolt head of the bolt, the nut is integrally made into a nut body which is provided with a bottom part, a clamping middle part and a pin-shaft top part, and a screw hole penetrating through the bottom part, the clamping middle part and the pin-shaft top part is drilled on the nut body. When the anti-dismantling bolt and nut assembly is applied, a special tool is equipped for the inner hexagonal screw hole which is different from the standard caliber, meanwhile, an installing hole having the same structure with that of the nut is drilled on an applied product, and the nut is embedded into the installing hole and is not protruded outside, so that a good anti-dismantling effect can be achieved; and when the applied product is installed outdoors for application, the anti-dismantling bolt and nut assembly has the good anti-dismantling effect and cannot be easily stolen or taken. The anti-dismantling bolt and nut assembly has the characteristics of anti-dismantling effect and simple structure and can be widely applied to various metal products.
Description
Technical field
The utility model relates to a kind of bolt and nut component.
Background technique
Existing bolt and nut component mostly is not possess the tamper function, makes some metal products (as metal railing product, guardrail product) be installed in the open air, is often stolen away by the ragpicker easily, makes the owner of these metal products often will suffer unnecessary loss.
The model utility content
The purpose of this utility model is to solve above-mentioned deficiency, and a kind of have tamper function, tamper bolt and nut component that Security is good, simple in structure are provided.
The technical solution of the utility model is achieved in that
A kind of tamper bolt and nut component, comprise bolts and nuts, its characteristics are that the bolt head of described bolt is provided with the interior hexagonal screw different with the standard bore, described nut is the nut body that one is made bottom, clamping middle part and bearing pin top, has the screw that runs through bottom, clamping middle part and bearing pin top on this nut body.
Technical characterstic of the present utility model:
On the bolt head of bolt, be provided with the interior hexagonal screw different owing to adopt with the standard bore, and nut is become by the bottom, the nut body structure that clamping middle part and bearing pin top constitute, make the utility model when using, for the interior hexagonal screw different with the standard bore is equipped with special tool, on the product that is employed, offer simultaneously the mounting hole identical with nut structure, nut is flush-mounted in this mounting hole do not protrude outside, can reach good tamper effect, when making the product that is employed be installed in outdoor application, have very tamper effect, can not stolen away easily.The utlity model has tamper effect, characteristic of simple structure, can use widely on the various metal products.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of tamper bolt and nut component described in the utility model, comprise bolt 1 and nut 2, in order to realize the purpose of this utility model, the bolt head of described bolt 1 is provided with the interior hexagonal screw 11 different with the standard bore, described nut 2 is made the nut body at bottom 21, clamping middle part 22 and bearing pin top 23 for one, has the screw 24 that runs through bottom 21, clamping middle part 22 and bearing pin top 23 on this nut body.When using, for the interior hexagonal screw different with the standard bore 11 is equipped with special tool, on the product that is employed, offer and the identical mounting hole of nut 2 structures simultaneously, nut 2 is flush-mounted in this mounting hole do not protrude outside, can reach good tamper effect, when making the product that is employed be installed in outdoor application, have very tamper effect, can not stolen away easily.
