Abstract
The utility model discloses a mechanical bolt structure. A groove which is shaped like a Chinese character 'yi' is supplied for using of a plain end screw driver and arranged at the bottom of a concave inner hexagon of a hexagonal head which is arranged on a bolt. Due to the fact that a structure is arranged on the head portion of the bolt and supplied for a wrench or the plain end screw driver to dismantle the bolt, the existing problem of the present bolt can be solved. The mechanical bolt structure has the advantages that the groove which is shaped like the Chinese character 'yi' is supplied for using of the plain end screw driver and arranged at the bottom of the concave inner hexagon of the hexagonal head which is arranged on the bolt, and the mechanical bolt structure can be supplied for the wrench or the plain end screw driver to unscrew or screw up, so that the wrench or the plain end screw driver is used for dismantling the bolt, and use effect is good.
Description
Technical field
The utility model relates to a kind of bolt arrangement, and particularly a kind of mechanical bolt structure belongs to the mechanical standard parts technical field.
Background technique
At present, bolt is to use widely a kind of part in the machine-building, bolt is many to be fastenedly connected the part of use by head and screw rod (with an externally threaded cylindrical body) class dimerous, now, be provided with on the bolt can be for hex head bolt head or the hexagon socket head cap screw head of spanner or inner hexagon spanner dismounting more, yet, the present head of bolt, it does not also arrange the structure that spanner or screw-driver all can assembling-disassembling bolts, easily like this brings passive in the use.
Summary of the invention
The purpose of this utility model is: a kind of mechanical bolt structure is provided, overcomes the existing defects of existing bolt arrangement, thereby can bring the facility in the use.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of mechanical bolt structure, and it is comprised of bolt, hexagon head, interior hexagonal, straight groove; The bottom of the interior hexagonal that it is recessed at the hexagon head of bolt setting is provided with can be for the straight groove of flat mouth screw-driver, in this way, because the head of bolt is provided with can be for the structure of spanner or flat mouth screw-driver assembling-disassembling bolt, therefore, it can improve the problem that present bolt exists.
The beneficial effects of the utility model: the bottom of the interior hexagonal that it is recessed at the hexagon head of bolt setting is provided with can be for the straight groove of flat mouth screw-driver, and it can be unscrewed or tighten and assembling-disassembling bolt for spanner or flat mouth screw-driver, thereby using effect is good.
