Description
Technical field
The utility model relates to a kind of bolt, and specifically a kind of grooved wedging formula is sold anti-theft bolt directly to households.
Background technique
Plain bolt has characteristics easy to loading and unloading, but the offender also can utilize the loading and unloading property of bolt to carry out theft crime, their common handling instrument easy to use can reach the purpose of crime at short notice, cause a large amount of public and civilian installations, such as stolen or destructions such as the guardrails on electric power pylon and the expressway, cause heavy losses to the country and people's life.
For addressing this problem, adopt electric welding weldering nut cap usually, or make bolt thread produce destructive distortion with brute force, reach not detachable antitheft purpose, but these methods are time-consuming, existing people have also invented some anti-theft bolts, but all there is complex structure, processing difficulties, the defective of cost costliness.
The utility model content
The purpose of this utility model provides and a kind ofly both can stop effectively that the improper dismounting of nut is promptly antitheft, easy to use again, laborsaving, saving of labor and simple in structure, and easy to process, grooved wedging formula with low cost is sold anti-theft bolt directly to households.
The utility model comprises screw bolt and nut, it is characterized in that: bolt screw front end portion has one and is
Oblique crank Z is to notch, and the nut madial wall has at least one and the axial notch groove to a synthetic axial bore, anti-stealing and selling and the axial bore stationary fit.
The described round taper that is processed into the wedge shape inclined-plane for front end of stealing and selling.
During use, nut is threaded onto on the bolt screw front end, make axial notch that one of them groove that the nut madial wall has and screw front end portion have to a synthetic axial bore, front end is processed into the promptly anti-insertion axial bore of stealing and selling of round taper on wedge shape inclined-plane, beat the anti-exposed parts of stealing and selling with hammering, wedge advances in the axial bore then to prevent stealing and selling at an easy rate, and it is in aggregates that nut, bolt are sold directly to households, antitheft with it.
The utility model effect
The utility model not only can be antitheft effectively, easy to use, assembles laborsaving, saving of labor, and simple in structure, easy to process, with low cost, is beneficial to popularization.
