Abstract
The utility model discloses a kind of Novel bolt, comprise bolt head and screw rod, mounting groove on described bolt head, described screw rod is provided with the mounting rod with mounting groove clamping, described bolt head and screw rod removably connect, and described bolt head two ends are provided with two groups of cross recesses entered for screw-driver.The utility model has the following advantages and effect: bolt head and screw rod dismountable while, be equipped with cross recess at two ends, reach the object repeatedly utilized, improve the utilization rate of bolt, waste can not be caused easily.
Description
Technical field
The utility model relates to fastener areas, is specifically related to a kind of Novel bolt.
Background technique
Bolt is by bolt head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, for being fastenedly connected two mechanical machine part with through hole.Bolt daily life when in and in panel beating and machine tooling technical field in the middle of, be absolutely necessary, but when repeatedly twisting this bolt, no matter be that straight screwdriver or Phillips screwdriver all can be conflicted with the groove on bolt mutually, but some bolt strengths are not high enough, or during excessive screwing force, all can cause the wearing and tearing of the groove on bolt head, repeatedly use after can screw-driver can not by groove by bolt tightening, such screw is substantially scrapped, utilization efficiency is low, the life-span is shorter, causes very polymetallic waste.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide one repeatedly to use, the Novel bolt of long service life.
For achieving the above object, the utility model provides following technological scheme: a kind of Novel bolt, comprise bolt head and screw rod, mounting groove on described bolt head, described screw rod is provided with the mounting rod with mounting groove clamping, described bolt head and screw rod removably connect, and described bolt head two ends are provided with two groups of cross recesses entered for screw-driver.
By adopting technique scheme, all cross recess is provided with at the two ends of bolt head, can for the screw-driver of a word or cross, be provided with two simultaneously, guarantee when after one of them wearing and tearing, can use another cross recess for, expand the using scope of this bolt, all be worn bad at two groups of cross recesses when one end simultaneously, bolt head can be disassembled from screw rod, change an installation direction, can again utilize, make a bolt can use four times, the bolt compared to existing technology extends service life, makes it possible to repeatedly use.
Of the present utility modelly to be set to further: described mounting rod is provided with annular protrusion, and described mounting groove is provided with the circular groove with annular protrusion clamping.By adopting technique scheme, interference fit between mounting rod and mounting groove, screw rod and bolt head can tentatively be connected and fixed, both are not easily separated, on mounting rod, be provided with annular protrusion simultaneously, mounting groove is provided with circular groove, and both realize clamping, and what bolt head and screw rod were fixed is more firm.
Of the present utility modelly to be set to further: described mounting rod is six prisms.
By adopting technique scheme, mounting rod is preferably six prisms, and mounting groove is also six prism grooves simultaneously, make when the cross recess on bolt head is all worn, hexagon wrench can also be adopted to rotate this bolt, reach the object reused for the third time, improve the utilization ratio of bolt.
Of the present utility modelly to be set to further: the two ends of described mounting groove are also provided with the groove in the shape that caves in.
By adopting technique scheme, groove be arranged so that the front end of screw-driver can be entered in mounting groove when using Phillips screwdriver, better make that screw-driver is chimeric with cross recessed to be used.
The utility model has following advantage: bolt head and screw rod dismountable while, be equipped with cross recess at two ends, reach the object repeatedly utilized, improve the utilization rate of bolt, waste can not be caused easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, bolt head; 2, screw rod; 3, mounting groove; 4, mounting rod; 5, cross recess; 6, annular protrusion; 7, circular groove; 8, groove.
Embodiment
With reference to Fig. 1, the utility model screw embodiment is described further.
A kind of Novel bolt, comprise bolt head 1 and screw rod 2, mounting groove 3 on described bolt head 1, described screw rod 2 is provided with the mounting rod 4 with mounting groove 3 clamping, described bolt head 1 and screw rod 2 removably connect, and described bolt head 1 two ends are provided with two groups of cross recesses 5 entered for screw-driver.
Cross recess 5 is all provided with at the two ends of bolt head 1, can for the screw-driver of a word or cross, be provided with two simultaneously, guarantee when after one of them wearing and tearing, can use another cross recess 5 for, expand the using scope of this bolt, all be worn bad at two groups of cross recesses 5 when one end simultaneously, bolt head 1 can be disassembled from screw rod 2, change an installation direction, again can utilize, make a bolt can use four times, bolt compared to existing technology extends service life, makes it possible to repeatedly use.
Preferably, interference fit between mounting rod 4 and mounting groove 3, screw rod 2 and bolt head 1 can tentatively be connected and fixed, both are not easily separated, on mounting rod 4, be provided with annular protrusion 6 simultaneously, mounting groove 3 is provided with circular groove 7, and both realize clamping, and what bolt head 1 and screw rod 2 were fixed is more firm.
Preferably, mounting rod 4 is preferably six prisms, mounting groove 3 is also six prism grooves simultaneously, make, when the cross recess 5 on bolt head 1 is all worn, hexagon wrench can also be adopted to rotate this bolt, reach the object reused for the third time, improve the utilization ratio of bolt, groove 8 be arranged so that the front end of screw-driver can be entered in mounting groove 3 when using Phillips screwdriver, better make the chimeric use of screw-driver and cross recess 5.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
