Abstract
The utility model relates to a bolt with an outer hexagonal shape and an inner triangular shape, which comprises a bolt head (2) and a bolt neck (3) connected with the bolt head (2); and bolt threads (4) are arranged at the lower end of the bolt neck (3), the bolt head (2) is an outer hexagonal bolt head, and a triangular groove (1) is formed in the center of the end surface of the bolt head (2). Various tools can be selected for disassembly and installation according to different conditions, so that the bolt is not damaged easily, the service life is further prolonged, the disassembly work is convenient, and the maximal using effect of the bolt can be achieved.
Description
Technical field
The utility model relates to fastener areas, particularly relates to shape triangular shape bolt in a kind of profile hexagonal.
Background technique
In traditional mechanized equipment industry, the big and small bolt in the fastening piece is the most common, most common standard part, outer-hexagonal bolt particularly, and use amount is very big, and using scope is also wide especially.But in today that mechanized equipment makes rapid progress, often the General fasteners bolt can not satisfy the needs of present many occasions, and especially in some more special equipment occasions, the effect of General fasteners bolt is subjected to very big placing restrictions on especially.Particularly common outer-hexagonal bolt, by common spanner, after dismounting repeatedly, its outer-hexagonal can be worn with comparalive ease, thereby make hex head bolt become the fillet bolt, the fillet bolt has just lost the effect of fastening piece at all, and not only bolt has been scrapped, and some equipment configurations can't be mounted and dismounted, bring great inconvenience to actual production work; Sometimes will destroy could solving the production practical problem after bolt or the device structure even, it is very big inconvenient and waste to bring to the user.
Summary of the invention
Technical problem to be solved in the utility model provides shape triangular shape bolt in a kind of profile hexagonal, makes bolt can reach maximum using effect.
The technological scheme that its technical problem that solves the utility model adopts is: shape triangular shape bolt in a kind of profile hexagonal is provided, comprises bolt head, the bolt neck that links to each other with described bolt head; It is the outer-hexagonal shape that described bolt neck subordinate end has bolt thread, described bolt head, and there is triangular groove at its end face center.
Described triangular groove is the equilateral triangle groove.
Beneficial effect
Owing to adopted above-mentioned technological scheme, the utility model compared with prior art, have following advantage and good effect: the utility model makes full use of the interior shape triangular shape of profile hexagonal that the bolt top forms, thereby the using effect of bolt is increased greatly, not only can use common spanner, sleeve to mount and dismount, can also use special instrument to mount and dismount, and after outer-hexagonal has been worn fillet, can there be other method actively to remedy, can reaches the installation and removal effect smoothly.
Description of drawings
Fig. 1 is an end view drawing of the present utility model;
Fig. 2 is an outline drawing of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As depicted in figs. 1 and 2, shape triangular shape bolt comprises bolt head 2, the bolt neck 3 that links to each other with described bolt head 2 in a kind of profile hexagonal; There is bolt thread 4 described bolt neck 3 lower ends, and described bolt head 2 is the outer-hexagonal shape, and there is triangular groove 1 at its end face center.Wherein, triangular groove 1 is the equilateral triangle groove.
This bolt can equally with plain bolt be applicable to many mechanized equipment occasions, and especially the bolt of the special shape that profile develops simultaneously in it not only has the effect and the function of profile hex head bolt, and simultaneously the bolt head end have one recessed in triangle as the location.This bolt is very convenient to use, not only can use common wrench, sleeve to reach the effect of original standard piece bolt, and under the condition of using special tool, in the fastening of special bolts with when unclamping, because being subjected to conditioning each other of outer-hexagonal and interior triangle also should not skid, especially in particular cases, if there is not special tool dismounting effect to be affected at some.In addition, after the outer-hexagonal wearing and tearing cause fillet, can use special tool, can dismantle with fastening bolt at leisure as interior triangle location outer-hexagonal combined sleeve, the inner ring on this sleeve top is a hexagonal plum blossom shape, center column structure triangular in shape.Special bolts can be dismantled with several method respectively, comprising: special socket wrench, ordinary cartridge spanner, plum blossom shaped spanner, interior triangle spanner or the like, can both dismantle this bolt effectively, make bolt reach maximum using effect, make this bolt in common occasion and the maximum effect of special occasions performance.
Be not difficult to find that the utility model can be according to situation at that time under multiple occasion situation; select multiple instrument to carry out demounting bolt and be unlikely to, thereby the life cycle that has prolonged bolt has made things convenient for dismantlement work bolt failure; reach resource conservation, save time, the convenient effect of using.
Claims (2)
1. the interior shape triangular shape bolt of profile hexagonal comprises bolt head (2), the bolt neck (3) that links to each other with described bolt head (2); There is bolt thread (4) described bolt neck (3) lower end, it is characterized in that, described bolt head (2) is the outer-hexagonal shape, and there is triangular groove (1) at its end face center.
2. shape triangular shape bolt in the profile hexagonal according to claim 1 is characterized in that described triangular groove (1) is the equilateral triangle groove.
