Other connection structures such as internal screw thread or external screw thread.
When carrying out pipe-line system pressure testing detection, pressure testing instrument described in the utility model is connected using 4 one end of hose first
One end of pipe fitting, the hose 4 is connected in the female connector main body 1 by the pipe fitting joint structure 14, and it is described into
Water hole 15 is connected to the hose 4, to collectively form pressure testing instrument tube joint assembly described in the utility model；Then, then pass through
The cooperation for being screwed on block 13 and rotary groove 22 snaps fit onto pressure testing instrument pipe fitting activity in pin end main body, the grafting at this time
Column 12 will be also inserted into the apopore 21；Then, then by the other end of hose 4 it is connected to the test nozzle of pipe-line system；
The pressure testing that finally starting the pressure testing instrument can be completed to pipe-line system detects.
Referring to Fig.1, Fig. 2, in the present embodiment, specifically, the one end of the rotary groove 22 far from 2 end of connector
It is provided with the first limit rib 23, the second limit rib 16 with first limit rib 23 cooperation is provided on the block 13 that is screwed on；
It can make to keep clamping between pressure testing instrument pipe fitting and pin end main body by first limit rib 23 and the second limit rib 16
State, avoid the problem that because by external external force etc. influence due to make it is above-mentioned between the two generate relative rotation be detached from, and
And it can also be played by above structure and remind whether operator will be screwed on the purpose of block 13 and 22 rotary clamping of rotary groove in place.
Specifically, the first seal groove 17 is provided on the lateral wall of the inserting column 12 in the present embodiment referring to Fig. 4,
First seal 3 is installed in first seal groove 17, it can be to avoid fluid from the grafting by above-mentioned first seal 3
Gap leakage between column 12 and inlet opening 15 comes out.
Referring to Fig. 5-7, pipe-line system to be tested is connected for convenience, in the present embodiment, specifically, the hose 4
The other end be also connected with pipe fitting joint, and described in the pipe fitting joint constitutes together with the hose 4 and pressure testing instrument pipe fitting
Pressure testing instrument tube joint assembly；Also, in the present embodiment, specifically, the pipe fitting joint includes the pipe sheet with hollow cavity
Body 5, the retainer ring 6 for being mounted on 5 upper end of tube body；6 lower end of retainer ring slots to form several claws 61,61 shape of claw
At there is the retention bead protruded outward 62；6 lower end of retainer ring is inserted into the hollow cavity 51, the hollow cavity 51
It is inside provided with and the matched positive stop lug boss 52 of the retention bead 62；The lower part of the tube body 5 is provided with pipe fitting connection screw thread
53, the outer diameter of 6 upper end of retainer ring is greater than the internal diameter of 51 upper end opening of hollow cavity；The hose 4 passes through the retainer ring 6
And the connection realized with pipe fitting joint is entered in hollow cavity 51.The pipe fitting joint is arranged to above structure, is being connected
Hose 4 need to be only inserted directly into retainer ring 6 when hose 4 and pipe fitting joint, without the connection in hose 4 and pipe fitting joint
The end setting structures such as screw thread and nut；Also, by the pipe fitting connection screw thread 53 of 5 lower part of tube body, tube body 5 can be made direct
It is screwed onto pipe-line system to be tested；Therefore cost is advantageously reduced using above-mentioned pipe joint structure, improves installing and dismounting speed
Degree and efficiency.
In order to enable retainer ring 6 preferably to fix hose 4, the hose 4 is avoided to fall off from pressure testing pipe fitting, specifically
Ground is formed with inwardly protruded clamping convex ribs 63 on the inside of the claw 61；When hose 4 passes through retainer ring 6, hose 4 will be pushed and be pressed from both sides
Tight convex ribs 63 move outward, to make a deformation outside claw 61, and a clamping reaction force are generated to hose 4, thus real
The clamping of existing hose 4；Also, retainer ring 6 is passed through for the ease of hose 4, it is preferable that it clamps in convex ribs 63 and is sloped downwardly setting,
To make it have guiding role.
Also, in order to enable the upper end of retainer ring 6 to be bonded with 5 upper surface of tube body, in the present embodiment, specifically, institute
The lip 64 that 6 upper end of retainer ring is formed with evagination is stated, the outer diameter of the lip 64 is greater than the interior of 51 upper end opening of hollow cavity
Diameter.Also, specifically, the hollow cavity 51 is provided with up-small and down-big bell-mouth structure of air 54, the bell-mouth structure of air 54
In 52 lower section of positive stop lug boss, and 64 lower surface of the lip is greater than institute to the height between 62 upper surface of retention bead
State 52 lower surface of positive stop lug boss to the 51 oral area upper end of hollow cavity height；It, can by the difference being arranged in above-mentioned height
So that retainer ring 6 can be realized in the hollow cavity 51 it is small-scale move up and down, and by bell-mouth structure of air 54
Setting, when retention bead 62 can be made to be bonded positive stop lug boss 52, claw 61 can not be expanded outwardly, and when claw 61 is displaced downwardly to limit
When position protrusion 62 is located at the lower section of bell-mouth structure of air 54, claw 61 can normally expand outwardly deformation；Therefore, it is worn when by hose 4
When crossing retainer ring 6, hose 4 first will drive retainer ring 6 to move down, and retention bead 62 is made to come the lower section of bell-mouth structure of air 54, block at this time
Pawl 61 is expanded outwardly to allow hose 4 to pass through；And after hose 4 passes through retainer ring 6, when being pullled external force suddenly, retainer ring 6 also will
It first follows hose 4 to move up, and so that retention bead 62 is bonded positive stop lug boss 52 and deviate from ontology to limit retainer ring 6, and due to this
When claw 61 cannot expand outwardly, therefore retainer ring 6 also will tightly grip both hose 4, avoid hose 4 from pulling out of retainer ring 6.It is needing
When artificially hose 4 being removed from pressure testing pipe fitting, by manually pushing retainer ring 6, retention bead 62 is made to be moved to horn mouth
At the lower section of structure 54, then pull hose 4 that can remove hose 4.
In order to realize the sealing between hose 4 and ontology, in the present embodiment, specifically setting in the hollow cavity 51
There is second seal 7, the second seal 7 is located at the lower section of the retainer ring 6.
It is illustrating for progress to be implemented to the preferable of the utility model, but the utility model creation is not limited to institute above
Embodiment is stated, those skilled in the art can also make various be equal without departing from the spirit of the present invention
Deformation or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
