Abstract
The utility model discloses an easily pull wrong bolt, including the bolt body, the bolt body includes spiral shell head, screw rod, the spiral shell head be regular hexagon's hexagonal drive head for the cross section, one side is connected the screw rod, the screw rod be the cylinder structure, the surface is provided with the screw thread, the spiral shell head with the screw rod for the whole body structure that forms of making, wherein the vertical the central axis department of bolt body is provided with one and runs through the rectangle through -hole of bolt, it can be right to put into assorted cuboid vertical rod in the through -hole the bolt is pulled and is twisted the operation, the through -hole runs through spiral shell head and screw rod for the stress point increases, dispersible atress. In this way, the utility model discloses simple structure, novelty are provided with a through -hole that runs through at the vertical the central axis of bolt, in the time of economize in raw materials and cost, return the wrong operation of pulling of bolt and facilitate, utilize the rectangular body rod of assorted to revolve and twist, let the atress disperse for it is wrong more convenient, lighter to pull, has certain economic benefits and market prospect.
Description
Technical field
The utility model relates to metal firmware field, particularly relates to a kind of easily twisting bolt.
Background technique
Bolt is the one of mechanical parts, the cylindrical threaded fastening piece of adapted nut, by head and a screw rod class fastening piece dimerous, need and nut screw connection, for being fastenedly connected two parts with through hole, at present, the bolt arrangement on market is similar, mostly be solid construction, twisting mode is all lived by spiral shell head-clamp by spanner, and then screw, twisting like this is very painstaking, spanner force bearing point on spiral shell head is few, operates very not light.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of easily twisting bolt, can contribute to force dispersion when twisting, and operation is lighter, and twisting is easier.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of easily twisting bolt, it is characterized in that, comprise: bolt body, described bolt body comprises spiral shell head, screw rod, described spiral shell head is cross section is orthohexagonal hexagonal spiral shell head, screw rod described in side connects, described screw rod is cylindrical structure, surface is provided with screw thread, described spiral shell head and described screw rod are the overall integrative-structure manufactured, wherein, at the vertical central axis place of described bolt body, be provided with the rectangular through-hole that runs through described bolt, insert the cuboid vertical bar matched in through hole and can carry out twisting operation to described bolt, described through hole runs through described spiral shell head and screw rod, force bearing point is increased, dispersible stressed.
In the utility model preferred embodiment, the material of described bolt body is carbon steel.
In the utility model preferred embodiment, the vertical central axis of described through hole and the vertical central axis of described bolt body are same straight line.
In the utility model preferred embodiment, described bolt body is supporting a metallic vertical bent rod.
The beneficial effects of the utility model are: the utility model structure is simple, novel, the vertical central axis of bolt is provided with a through hole run through, economize in raw materials and cost while, the twisting operation of returning bolt provides convenient, the rectangular body rod matched is utilized to screw, allow force dispersion, make twisting more convenient, lighter, have certain economic benefit and market prospects.
