The model utility content

Because the shortcoming of aforementioned prior art, the purpose of the utility model ties up in the pipe joint that a kind of tool pooling feature is provided, it is designed one and has the rubber bellows and can absorb the pressure that produces in the body, and just rubber bellows and body can be mutually combined with clip, make assembling process have preferable convenience.

For reaching aforementioned model utility purpose, the pipe joint of the tool pooling feature that the utility model is designed, it is to include rubber bellows, four clips and four fixed blocks, wherein:

This rubber bellows system is hollow shape, and it is formed with at least one spheroid, and two ends are formed with an opening respectively, and its end face projection is formed with an annular solid, and this annular solid outer rim has extended to form one and supported the ring of pulling;

This clip is a curved block, and its inner side surface indent is formed with a containing groove, and two ends are extended with a fixed base respectively, this fixed base runs through and is provided with a perforation, two clips system is symmetrical arranged, and it is an annular containing groove that two containing grooves are combined to form, and this annular containing groove is equipped with to the ring of pulling;

The perforation of two clips of correspondence is run through in this fixed block system, and clip is positioned on the rubber bellows.

The pipe joint of described tool pooling feature wherein should support the ring free end system's bending and towards annular solid of pulling.

The pipe joint of described tool pooling feature, wherein this annular solid outer wall is equipped with a short tube, and this short tube outer wall is equipped with a groove, and short tube one end face is butted on the annular solid.

The pipe joint of described tool pooling feature, wherein this clip is formed with a flange respectively in the containing groove both sides, and the flange of a side is sticked in the groove of short tube.

The pipe joint of described tool pooling feature, wherein this fixed block is the combination of screw and nut.

The pipe joint of the tool pooling feature that the utility model provided, the advantage of acquisition and effect enhancement comprise:

(1) the utility model has reduced the member of flange and conversion adapter compared to prior art, and is beneficial to the manufacturing and the assembling of product, and can reduce cost, and then improves the competitive ability of product on market.

(2) just rubber bellows and groove type body can be connected with clip, operation is convenient, so working efficiency is promoted, and owing to not carrying out weld job, makes working environment safer.
