Description

Shape five-cornuted sleeve in a kind of profile hexagonal

Technical field

The utility model relates to the mechanized equipment field of tool, particularly relates to shape five-cornuted sleeve in a kind of profile hexagonal, can be used for shape five-cornuted special bolts installation and removal in the profile hexagonal.

Background technology

In traditional mechanized equipment industry, the big and small bolt in the securing member is the most common, most common standard part, outer-hexagonal bolt particularly, and use amount is very big, and the scope of application 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 very limited especially.Particularly common outer-hexagonal bolt, by common spanner, after dismounting repeatedly, outer-hexagonal can be worn with comparalive ease, thereby make hex bolts become the fillet bolt, and the fillet bolt has just lost the effect of securing member at all, not only bolt has been scrapped, and some equipment configurations can't be mounted and dismounted, bring great inconvenience to real work, sometimes to destroy bolt or device structure even and just can deal with problems later on, cause the inconvenience that product cost increases and applying unit is keeped in repair of bolt applying unit.

Summary of the invention

Technical problem to be solved in the utility model provides shape five-cornuted sleeve in a kind of profile hexagonal, is used to mount and dismount shape five-cornuted bolt in the profile hexagonal.

The technical scheme that its technical problem that solves the utility model adopts is: shape five-cornuted sleeve in a kind of profile hexagonal is provided, comprise sleeve body, described sleeve body tail end is provided with square opening, and described sleeve body top inner ring is a hexagonal plum blossom shape, and its center is the pentagon column structure.

Described pentagon column structure is positive pentagon column structure.

Beneficial effect

Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model makes full use of inner ring hexagonal plum blossom shape and the center pentagon column structure that the top forms, thereby the effect of the special bolts of shape five-cornuted in the dismounting profile hexagonal is increased greatly, utilize the utility model that the special bolts of shape five-cornuted in the profile hexagonal is mounted and dismounted, can make special bolts reach best installation and removal effect smoothly.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment 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.

Embodiment 1

Shown in Fig. 1,2 and 3, shape five-cornuted sleeve in a kind of profile hexagonal comprises sleeve body 3, and described sleeve body 3 tail ends are provided with square opening 4, and described sleeve body 3 top inner rings 1 are hexagonal plum blossom shape, and its center 2 is the pentagon column structure.Wherein, the pentagon column structure is positive pentagon column structure.This sleeve is primarily aimed at the special bolts of shape five-cornuted in a kind of profile hexagonal, and the bolt head of this special bolts is the outer-hexagonal shape, and there is the pentagon groove at its end face center.

Generally, the utility model and ordinary cartridge are adopted the use that uses the same method, the relevant position of special bolts is aimed on the sleeve body top, that is to say, the hexagonal plum blossom shape of sleeve body top inner ring is corresponding mutually with the outer-hexagonal shape of special bolts head, the pentagon column structure at center, sleeve top is corresponding mutually with the pentagon groove of bolt head end face, bolt head is entered in the sleeve, use sleeve handle to insert in the square opening of sleeve tail end then, just can carry out left-handed or dextrorotation, the dismounting special bolts is just very convenient like this, make special bolts be not easy to damage, and under the situation that special bolts outer-hexagonal and Nei Wujiao check and balance, should not skid and to bring into play the effect of its maximum.

Be not difficult to find, adopt the special bolts of five-cornuted in the utility model installing/dismounting outer-hexagonal, operating efficiency is improved, the function of special bolts has obtained performance, to the saving that mechanized equipment brings great convenience and bolt material, make special bolts reach best result of use.

Claims (2)

1. shape five-cornuted sleeve in the profile hexagonal, comprise sleeve body (3), described sleeve body (3) tail end is provided with square opening (4), it is characterized in that, described sleeve body (3) top inner ring (1) is a hexagonal plum blossom shape, and its center (2) are the pentagon column structure.

2. shape five-cornuted sleeve in the profile hexagonal according to claim 1 is characterized in that described pentagon column structure is positive pentagon column structure.
