Abstract
The utility model relates to a two unification multifunctional bolt, including the bolt head and with bolt head integrated into one piece's shank of bolt, the bolt head is the hexagon, the shank of bolt is cylindrical, the overhead cross recess that has seted up of bolt, the depth of groove is less than the bolt head height, the shank of bolt surface is provided with the screw thread, and this kind of bolt both can be with outer hexagonal, can open the sword with the cross again, fastens and opens the bolt, has solved current bolt and can only be fastened and open and easily be corroded problem by single instrument.
Description
Technical Field
The utility model relates to a hardware and tools technical field specifically is a two unification multi-functional bolts.
Background
The bolt is the general expression of fastener, and everyone's law of calling may all be different, and someone calls the screw, and someone calls bolt nail, and somebody calls the fastener, all is the bolt, and the bolt is mechanical part, the cylindrical threaded fastener of adapted nut. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. This form of connection is known as a bolted connection. If the nut is screwed off from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection;
the bolt is divided into the following parts according to the shape of the head: there are hexagonal head, round head, square head, countersunk head, etc., among which the hexagonal head is most commonly used, but bolts of various shapes can be fastened and opened only by a single tool and are easily corroded when used, so that the prior art has yet to be developed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a two unification multi-functional bolts to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a two-in-one multifunctional bolt comprises a bolt head and a bolt rod integrally formed with the bolt head, wherein the bolt rod is cylindrical;
the bolt head is provided with a cross-shaped groove, and the depth of the groove is smaller than the height of the bolt head;
and the outer surface of the bolt rod is provided with threads.
Optionally, the bolt head is hexagonal.
Optionally, the cross-shaped grooves are located on two symmetry axes of the hexagon.
Optionally, the bolt head and the bolt shaft are both made of an alloy material.
Optionally, the edge of the upper surface of the bolt head is cut into a circular arc shape.
Optionally, the bolt head and the outer surface of the bolt rod are uniformly coated with a conductive anticorrosive layer.
Optionally, the conductive anticorrosive layer is made of a cobalt-based alloy.
Optionally, the thickness of the conductive corrosion-resistant layer is 1mm-1.5 mm.
Compared with the prior art, the utility model provides a two unification multifunctional bolt possesses following beneficial effect:
the utility model discloses a set up cross recess and electrically conductive anticorrosive coating for this kind of bolt not only can use outer hexagonal but also can use cross sword fastening and open the bolt, more facilitates the use, and convenient the tightening is more corrosion-resistant, and life is longer.
