Description

Five jiaos of interior shape triangular shape sleeves of a kind of profile

Technical field

The utility model relates to the mechanized equipment field of tool, particularly relates to five jiaos of interior shape triangular shape sleeves of a kind of profile, can be used for five jiaos of interior shape triangular shape special bolts installation and removal of profile.

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, its outer-hexagonal can be worn with comparalive ease, thereby makes hex bolts become the fillet bolt, and the fillet bolt has just lost the effect of securing member at all.In order to change this awkward situation, five corner bolts outside common the employing, but outer five corner bolts equally also can become the fillet bolt through repeatedly dismantling, thus make bolt scrap, 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 five jiaos of interior shape triangular shape sleeves of a kind of profile, is used to mount and dismount five jiaos of interior shape triangular shape bolts of profile.

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

Described triangle column structure is the equilateral triangle 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 five jiaos of plum blossom shapes of inner ring and the central cam shape column structure that the top forms, thereby the effect of the special bolts of five jiaos of interior shape triangular shapes of dismounting profile is increased greatly, utilize the utility model that the special bolts of shape triangular shape in five jiaos of the profiles 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, five jiaos of interior shape triangular shape sleeves of a kind of profile comprise 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 five jiaos of plum blossom shapes, its center 2 column structures triangular in shape.Wherein, triangle column structure is the equilateral triangle column structure.This sleeve is primarily aimed at the special bolts of five jiaos of interior shape triangular shapes of a kind of profile, and the bolt head of this special bolts is outer five-cornuted, and there is triangular 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, five jiaos of plum blossom shapes of sleeve body top inner ring are corresponding mutually with the outer five-cornuted of special bolts head, the triangle column structure at center, sleeve top is corresponding mutually with the triangular 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 Wai Wujiao and interior triangle 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 the outer five jiaos of interior triangular shapes of the utility model installing/dismounting, 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. A triangular sleeve with a pentagonal shape, comprising a sleeve body (3), the tail end of the sleeve body (3) is provided with a square hole (4), it is characterized in that the sleeve body (3) The top inner ring (1) is in the shape of a pentagonal quincunx, and its center (2) is in a triangular columnar structure. 2. The triangular sleeve with a pentagonal interior shape according to claim 1, wherein the triangular columnar structure is an equilateral triangular columnar structure.
