Description
Technical field
This utility model is related to a kind of pipe joint arrangement.
Background technology
It is bamboo joint type currently for back leakage connection, for oil return pipe adopts the fuel pipe attachment structure of nylon tube, in dress
Timing, needs manually to pack on back leakage connection by nylon tube, and connected mode is interference fit form, harder when therefore assembling.
Reduce according to by bamboo joint type back leakage connection diameter, it is understood that there may be the situation of nylon tube abjection.Again due to nylon material attribute
Reason, tubing is harder, is especially apparent when temperature is low, in assembling process, there is suit difficulty, especially operator is worn
When glove have oil or oil pipe surface to have oil, assembling can be led to more difficult.
Utility model content
For overcoming drawbacks described above, this utility model provides a kind of pipe joint arrangement, and can not only reduce the assembling magnitude of interference makes
Must assemble and be more prone to operate, and compress the sealing that can ensure between pipe joint and connecting tube using nut outside and be connected
Tightness.
For solving above-mentioned technical problem, the technical solution of the utility model is：A kind of pipe joint arrangement, including joint originally
Body, the outer surface of described joint body has from the axially disposed lead segment in end and accepts section, described lead segment with described
Accept between section as seamlessly transitting and external diameter is by the little divergent segment becoming larger；Described undertaking section is away from described divergent segment side
Described joint body is provided with annular protrusion, and the external diameter of described annular protrusion is more than the described external diameter accepting section；Described convex annular
It has been threaded connection and has withheld nut on rising, described withheld nut and corresponding described lead segment, divergent segment and accept between section
Form accommodating chamber, and the described inwall withholding nut is provided with attaching part corresponding with described flaring fragment position.
As further improving, described attaching part be arranged on described in withhold on nut inner wall interior chamfering, and described
The small end of interior chamfering is to withhold end.
As further improving, the described described joint body accepted between section and described annular protrusion is provided with annular
Groove.
Employ above technical scheme, the beneficial effects of the utility model：
Due to lead segment, divergent segment being provided with joint body and accept section, can be easily by nylon hence with lead segment
Pipe first imports on joint body, then promotes nylon tube to sequentially pass through divergent segment and accept section, and such attachment structure reduces Buddhist nun
The assembling magnitude of interference between dragon pipe and pipe joint, thus greatly reduce assembly difficulty, recycle and withhold nut compression nylon tube
Ensure that sealing, be fastenedly connected with joint body simultaneously, hereby it is ensured that the tightness that nylon tube is connected with pipe joint, overall
Structure is simple, is easy to operate.
Brief description
Fig. 1 is the structural representation of pipe joint；
Fig. 2 is the structural representation withholding nut；
Fig. 3 is pipe joint, nylon tube and the structural representation withholding nut assembling；
Shown in figure：1- joint body, 10- lead segment, 11- divergent segment, 12- accepts section, 13- annular groove, 14- annular
Projection, 2- withholds nut, chamfering in 20-, 3- nylon tube.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.
As a kind of jointly shown in Fig. 1 and Fig. 2, pipe joint arrangement, have from end along axle in the outer surface of joint body 1
To the lead segment 10 of arrangement with accept section 12, and lead segment 10 and accepting between section 12 as seamlessly transitting and external diameter is gradually become by little
Big divergent segment 11.
Accept section 12 and be provided with annular protrusion 14, the external diameter of annular protrusion 14 away from the joint body 1 of divergent segment 11 side
More than the external diameter accepting section 12.The joint body 1 accepting between section 12 and annular protrusion 14 is provided with annular groove 13, annular
The setting of groove 13 can reduce the use level with nylon tube 3, makes assembling more laborsaving.
Annular protrusion 14 is threaded connection and has withheld nut 2, withheld nut 2 and corresponding lead segment 10, flaring
Form accommodating chamber between section 11 and undertaking section 12, and withhold the inwall of nut 2 and be provided with withhold corresponding with divergent segment 11 position
Portion.As shown in Figure 2 it is preferable that attaching part is to be arranged on the interior chamfering 20 withheld on nut 2 inwall, and interior chamfering 20 is little
Hold as withholding end.Certainly attaching part can also select according to actual needs for being arranged on the structures such as the projection withholding on nut inner wall
Select.
Concrete operating principle is analyzed as follows：The external diameter of above-mentioned lead segment 10 is less than the internal diameter of nylon tube 3, accepts the outer of section 12
Footpath is more than the internal diameter of nylon tube 3；The inner chamber withholding nut 2, in addition to coordinating with attaching part, in addition guarantees to be enclosed within convex annular
Play 14 and be located on the nylon tube 3 on joint body 1, with reference to the installation diagram of Fig. 3.
Nut 2 first will be withheld during operation be enclosed within nylon tube 3, then pick up the guiding that nylon tube 3 is aligned on joint body 1
Section 10, so that nylon tube 3 is easily enclosed within lead segment 10, then proceedes to promote nylon tube 3, through divergent segment 11 and undertaking section 12
Nylon tube 3 is expanded afterwards, understands easily during nylon tube 3 because the presence of annular groove 13 continues to press on, until promoting nylon
Pipe 3 withstands on annular protrusion 14, now promotes to be enclosed within and withholds nut 2 on nylon tube 3, withholds nut 2 when promotion and feel
When there is resistance, when now withholding the interior chamfering 20 of nut 2 and being pressed on nylon tube 3, then can screw and withhold nut 2 and make
Withhold nut 2 and annular protrusion 14 screw-threaded coupling, screwing operations can make the end of withholding of interior chamfering 20 be tightly pressed against nylon simultaneously
On pipe 3, thus ensureing the connection reliability between nylon tube 3 and joint body 1 and sealing.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in this utility model
Protection domain within.
