Abstract
The utility model relates to a bolt-protecting cover, which belongs to the technical field of protecting cover structures. The bolt-protecting cover has the following characteristics: the bolt-protecting cover consists of three parts independent from each other, i.e. a cover lid, a cover body and a trapeziform gasket, the cover lid is a round metal piece with a mark at the central point, the cover body is a metal cylinder, the bottom of the cover body is provided with a step and the upper part of the cover body is provided with a spigot, the trapeziform gasket is a trapezoid-shaped gasket and is positioned in the lower opening of the cover body, the cover lid is positioned in the upper spigot of the cover body, and the cover lid is matched with the cover body in the manner of interference fit, i.e. the diameter of the cover lid is larger than that of the spigot. The bolt-protecting cover has the advantages of simple fabrication, wide application range, promising prospect, theft prevention, damage resistance, gas cutting resistance and rust resistance.
Description
One, technical field
The utility model relates to a kind of bolt shield, belongs to the protective roof structure technical field.
Two, background technique
At present, many open airs, roadside or open-air equipment all need to carry out with bolt fastening, but the protection of bolt is puzzlement people's a problem always.Because bolts and nuts often are exposed to the outside, through rainwash, being easy to will corrosion, even if using antiseptic oil safeguards, also can only play temporary transient effect, for the Security and the stability that improve equipment, people have to take often to change the method for bolt, the both wastes of manpower of this method, material resources waste financial resources again.And, often suffer lawless person's pilferage because the dismounting of bolt is also very convenient.
Three, summary of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, and provides a kind of simple in structure, of many uses, has bolt shield antitheft, tamper-proof, the anti-corrosion function.
Bolt shield of the present utility model, special way is to be made up of three separate parts, comprise cover cap 1, cover body 2 and trapezoidal pad 3, cover cap 1 has the metal disk of mark for central spot, cover body 2 is provided with the metal cylinder that step, top are provided with seam 4 for the bottom, trapezoidal pad 3 is for having the pad of trapezoidal shape, trapezoidal pad 3 is positioned at the lower openings place of cover body 2, cover cap 1 is positioned at top seam 4 places of cover body 2, be interference fit between cover cap 1 and the cover body 2, promptly the diameter of cover cap 1 is greater than the diameter of seam 4;
When with external force rotation cover body 2, rotate in order to prevent trapezoidal pad 3 thereupon, thereby cause bolt looseness, the height h1 of described trapezoidal pad 3 bottoms is greater than the height h2 of cover body 2 bottoms.
The utility model bolt shield, make simple, of many uses, prospect is considerable, can require to select for use unlike material, different model to make the protective housing of various antitheft, tamper-proof, gas cutting proofs, anti-corrosion according to different purposes.Such as being used for the antitheft of outdoor hanging outdoor unit of air conditioner, antitheft, the anti-corrosion of roadside, the open-air sign iron tower of fixing etc.; Utilize for another example this protective housing be used for automobile license plate fixedly the time, can prevent to steal criminal activities such as board, pseudo-board greatly.
Four, description of drawings
Fig. 1: be the utility model bolt shield structural representation;
Fig. 2: be the utility model embodiment 1 application schematic representation;
Five, embodiment
Following with reference to accompanying drawing, provide embodiment of the present utility model, be used for formation of the present utility model is further specified.
The bolt shield of present embodiment is with reference to figure 1,2, it is made up of three separate parts, comprise cover cap 1, cover body 2 and trapezoidal pad 3, cover cap 1 has the metal disk of mark for central spot, cover body 2 is provided with the metal cylinder that step, top are provided with seam 4 for the bottom, trapezoidal pad 3 is for having the pad of trapezoidal shape, trapezoidal pad 3 is positioned at the lower openings place of cover body 2, cover cap 1 is positioned at top seam 4 places of cover body 2, in order to make cover cap 1 be difficult for being disassembled, be interference fit between cover cap 1 and the cover body 2, promptly the diameter of cover cap 1 is greater than the diameter of seam 4; When with external force rotation cover body 2, rotate in order to prevent trapezoidal pad 3 thereupon, thereby cause bolt looseness, the height h1 of described trapezoidal pad 3 bottoms is greater than the height h2 of cover body 2 bottoms.
Using method: after bolt 6 is fastening with object 5, earlier cover body 2 is enclosed within on the bolt 6, then trapezoidal pad 3 is put into cover body 2, fix nut with socket wrench this moment, at last cover cap 1 is driven into the position of cover body 2 top seams 4; When needs are dismantled, electricity consumption is drilled on the cover cap 1 of centre mark thread tapping is screwed in and cover cap 1 can be ejected, expose nut can dismantle (antitheft when being main as the field, can make the cover cap of certain degree of hardness, common bit drills is motionless, and the design specialized drill bit solves the dismounting problem).
The utility model bolt shield, make simple, of many uses, prospect is considerable, can require to select for use unlike material, different model to make the protective housing of various antitheft, tamper-proof, gas cutting proofs, anti-corrosion according to different purposes.
