Description
Technical field
A kind of joint is the utility model is related to, joint is suppressed more particularly, to a kind of tubing.
Background technology
Suppress that to leak hunting be test stage important in tubing production link, in the prior art, pressure source is connected logical with tubing
Connect, then fastened flexible pipe with clip, the connected mode sealing effectiveness is poor, and efficiency is low frequently with flexible pipe；Also way be
A female adapter is welded above straight tube, after the completion of suppressing, then joint is cut off, and needs to polish smooth, this is easy for out
The appearance of existing problems of crack, and to suppress joint design complex for existing tubing, it is not easy to remove；And sealing is not strong.
The content of the invention
The shortcomings that the purpose of this utility model is to overcome prior art, there is provided a kind of tubing suppresses joint, it is possible to increase
Sealing, and it is simple in construction, easy to operate.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of tubing suppresses joint, including beats
Press input pipe, it is described suppress to be provided with input pipe suppress joint, it is described suppress joint include fittings body, tapered sleeve and fastening spiral shell
Mother, fixed block being provided with the fittings body, neck being provided with the tapered sleeve, the tapered sleeve is arranged in the fittings body
Portion, the tapered sleeve are mutually fixed by the cooperation of the fixed block and the neck, and through hole, the through hole are provided with the tapered sleeve
In up-narrow and down-wide structure, the tapered sleeve outer surface is provided with angular protrusions, and the fittings body surface is provided with external screw thread, described tight
Gu nut is connected with the external screw thread.
Further, using interference fit between the tapered sleeve and the fittings body.
Further, the joint quantity of suppressing is at least one, and subsequent application is suppressed on input pipe described.
The utility model has the advantages and positive effects of：Due to being passed through using above-mentioned technical proposal, fittings body, tapered sleeve
The cooperation of fixed block and neck realizes simple and compact for structure, only need to screw clamp nut and can complete to install, simple to operate
It is convenient, by the mutual cooperation of fittings body and tapered sleeve by tubing fixing seal, sealed reliable.

In figure：
1st, suppress input pipe 2, suppress joint 21, fittings body
211st, fixed block 22, tapered sleeve 221, neck
222nd, through hole 223, angular protrusions 23, clamp nut
Embodiment
The utility model is described further with reference to embodiment and accompanying drawing.
As shown in Figure 1 to Figure 3, the present embodiment provides a kind of tubing and suppresses joint, including suppresses input pipe 1, suppresses input
It is provided with pipe 1 and suppresses joint 2, suppressing joint 2 includes fittings body 21, tapered sleeve 22 and clamp nut 23, is set on fittings body 21
There is fixed block 211, fixed block 211 can left and right be movable on fittings body 21, is provided with neck 221 on tapered sleeve 22, tapered sleeve 22 is installed
Inside fittings body 21, tapered sleeve 22 is mutually fixed by the cooperation of fixed block 211 and neck 221, and through hole is provided with tapered sleeve 22
222, through hole 222 is in up-narrow and down-wide structure, and the outer surface of tapered sleeve 22 is provided with angular protrusions 223, and the surface of fittings body 21 is provided with outer
Screw thread, clamp nut 23 are connected with external screw thread, using interference fit between tapered sleeve 22 and fittings body 21.
Suppress the quantity of joint 2 and be at least one, subsequent application is on input pipe 1 is suppressed.
The course of work of this example：Joint 2 will be first suppressed before suppressing to install, and tapered sleeve 22 will be arranged in fittings body 21,
The angular protrusions 223 that the outer surface of tapered sleeve 22 is set are in contact with the inner surface of fittings body 21, produce frictional force, and installation more fastens, so
Clamp nut 23 is tightened on the external screw thread of fittings body 21 afterwards, with screwing for clamp nut 23, the fixation on fittings body 21
Block 211 and the clamping of neck 221 on tapered sleeve 22, after screwing, clamp nut 23, fittings body 21 and tapered sleeve 22 interfix.
In use, pipe material inner wall is inserted in the through hole 222 of tapered sleeve 22, up-narrow and down-wide structure is firmly secured to tubing
In tapered sleeve 22, now, tubing is fixed and sealed by the fittings body 21 and tapered sleeve 22 of interference fit, and opening pressure device can start
Suppress work of leaking hunting.
The beneficial effects of the utility model are：Due to passing through fixed block and card using above-mentioned technical proposal, fittings body, tapered sleeve
The cooperation of groove realizes simple and compact for structure, only need to screw clamp nut and can complete to install, simple and convenient, by connecing
The mutual cooperation of head body and tapered sleeve is by tubing fixing seal, sealed reliable.
One or more embodiments of the present utility model are described in detail above, but the content is only this practicality
New preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all according to present utility model application model
Made equivalent change and improvement etc. are enclosed, all should still be belonged within patent covering scope of the present utility model.
