Description

Cross fitting

Technical field

The utility model relates to a kind of cross fitting, specifically is a kind of cross fitting that is used to be communicated with three flexible pipes and a rigid conduit.

Background technique

Cross fitting is widely used in fields such as industry, civilian, decoration, generally is used to be communicated with fluid pipeline, specifically is to be used to be communicated with three flexible pipes and a rigid conduit (stereoplasm tube).The cross fitting of prior art comprises 101 and joints 102 of three butt heads (connect and chew), described joint 102 and three butt heads 101 are crossing distribution and are one, described joint 102 and three butt heads 101 all each have the through hole 103 that axially runs through, each end of one end of described joint 102 and three butt heads 101 is connected and the through hole 103 of this joint 102 and the through hole 103 of three butt heads 101 are interconnected, described joint 102 is provided with outside thread 104, described three butt heads 101 are equipped with a plurality of awl teeth 105, the microcephaly 106 of each awl tooth 105 is away from four connecting part, the major part 107 of each awl tooth 105 is near four connecting part, described a plurality of awl tooth 105 all is on the circular circumferential surface that is distributed in every butt head 101, the axis normal of described annulus and separately termination 101, the major part 107 of described a plurality of awl teeth 105 and microcephaly 106 near.When the user used this cross fitting, first swivel joint 102 made that the outside thread 104 on the joint 102 is tightened on the internal thread of fixing rigid conduit (interface), respectively three flexible pipes is locked on corresponding termination 101 then.

There is following defective in the cross fitting of prior art: because described a plurality of awl teeth 105 all are on the circular circumferential surface that is distributed in every butt head 101, so need be along axially the applying very big power and three flexible pipes could be locked on termination 101 separately of termination 101, so the fit process of flexible pipe and this cross fitting is required great effort very much; Again because the fit of flexible pipe and termination 101 is directly to advance directly, in case it is excessive that intraluminal fluid is pressed, the phenomenon of taking off flexible pipe just may appear dashing, so also need to take other security measure, as with iron wire or anchor ear etc. with the flexible pipe banding on termination 101, the consumption that had so both increased fastening piece promptly increases user cost, has increased operating procedure again; Also, only adapt to and adopt the manufacturing of mould casting craft,, make that the tightness of this cross fitting is relatively poor, generally can not be communicated with gas pipeline so occur bubble on the cross fitting unavoidably because described cross fitting is a monolithic construction.

The model utility content

The technical problems to be solved in the utility model is, provide a kind of flexible pipe laborsaving with its fit process, can reduce the cross fitting that operating procedure can also be communicated with gas pipeline.

Technical solution of the present utility model is, a kind of cross fitting with following structure is provided, it comprises a joint and three butt heads, described joint and three butt heads all each have the through hole I that axially runs through, described joint is provided with outside thread, it also comprises a link, described joint is fixed on the link, three butt heads are all removable to be installed on the link, the through hole I of the through hole I of described joint and three butt heads all is communicated with by link, described three butt heads are equipped with a plurality of awl teeth, the microcephaly of each awl tooth is away from link, the major part of each awl tooth is near link, and described a plurality of awl teeth join end to end and are on the circumferential surface that shape of threads is distributed in every butt head.

After adopting above structure, the utility model cross fitting compared with prior art has the following advantages:

Because described three butt heads are equipped with a plurality of awl teeth, described a plurality of awl tooth joins end to end and is on the circumferential surface that shape of threads is distributed in every butt head, so, the user when the fit flexible pipe of termination, do not need again along the termination axially apply very big power, but by the rotation flexible pipe, make flexible pipe be the awl tooth spiral commentaries on classics that shape of threads distributes relatively, very easily just can with the flexible pipe rotation set on the termination, like this, make that the fit process of flexible pipe and this cross fitting is very laborsaving; Because flexible pipe is very tight with screwing of the awl tooth that is the shape of threads distribution, avoided flexible pipe to be washed open again, so needn't re-use other fastening piece, reduced user cost, operating procedure has been lacked in letter.

Be fixed on the link owing to described joint again, three butt heads are all removable to be installed on the link, like this, the assembly that constitutes the utility model cross fitting link and joint can be by drop stamping and mach technology manufacturing, and technology manufacturings such as punching, machining screw on cylindrical steel can be passed through in the termination, and then each assembly assembled, like this, avoided because of adopting the mould casting craft on cross fitting, to produce the problem of bubble, so make this cross fitting have good air-tightness, make this cross fitting can be communicated with gas pipeline.
