Description

A kind of seal nipple

Technical field

The utility model relates to a kind of seal nipples.

Background technique

Existing connector is generally made of tube body and inserts, and the principle that inserts is expanded with heat and contract with cold by tube body is embedded in tube body Interior, using long afterwards, tube body is easy aging, keeps the compactness of tube body and inserts not high, to cause leak；And existing connector It is generally directly connected through a screw thread with inserts, tightness is not high, is also easy to cause drainage.

Utility model content

The utility model is exactly to solve to provide a kind of seal nipple technical problem that sealing effect is good.

In order to solve the above technical problems, a kind of technical solution of seal nipple of the utility model are as follows:

Including tube body and it is provided with the inserts of internal thread hole, the inserts is installed on tube body end, on the internal thread hole Connector is connected, further includes gasket；The inserts side is provided with multiple seal grooves；O-ring is all connected on the seal groove；Institute O-ring is stated between tube body and inserts；Card slot is also provided on the outside of the inserts；The tube body is equipped with the snap ring to match；Institute Snap ring is stated to be stuck on card slot；Step ring is equipped on the inside of the inserts bottom end；Through-hole is provided on the inside of the gasket；The through-hole diameter Less than step ring interior diameter；Gasket bottom end outer diameter is less than gasket front end external diameter；The gasket is connected to connector and platform Between rank ring；The step ring antetheca is butted on the rear wall of gasket, and connector rear wall is butted on the antetheca of gasket.

It is 3 that the seal groove, which has altogether, and corresponding O-ring is also 3.

What the utility model can achieve has the technical effect that the utility model makes the sealing of inserts and tube body using O-ring Effect is more preferable, keeps the sealing effect of inserts and connector more preferable using sealing shroud, is less than step ring using sealing shroud through-hole diameter Interior diameter, when connector screws extruding pad, the internal diameter front of step ring can firmly be adjacent to gasket, sealing effect It is good.

Detailed description of the invention

Utility model will be further described in detail below with reference to the attached drawings and specific embodiments:

Fig. 1 is a kind of cross-sectional view of seal nipple of the utility model；

Fig. 2 is the portion the A enlarged drawing of Fig. 1；

Fig. 3 is the structural schematic diagram after a kind of seal nipple connection connector of the utility model；

Fig. 4 is a kind of structural schematic diagram of seal nipple of the utility model；

Fig. 5 is a kind of explosive view of seal nipple of the utility model.

Specific embodiment

Further details of elaboration is made to the utility model with reference to the accompanying drawing.

Refering to fig. 1 to Fig. 5.

A kind of seal nipple including tube body 1 and is provided with the inserts 2 of internal thread hole 11, and the inserts 2 is installed on tube body 1 End connects connector 21 on the internal thread hole 11, further includes gasket 3；2 side of inserts is provided with multiple seal grooves 4；Institute It states and is all connected with O-ring 5 on seal groove 4；The O-ring 5 is between tube body 1 and inserts 2；2 outside of inserts is also provided with Card slot 6；The tube body 1 is equipped with the snap ring 7 to match；The snap ring 7 is stuck on card slot 6；Platform is equipped on the inside of 2 bottom end of inserts Rank ring 8；Through-hole 9 is provided on the inside of the gasket 3；9 diameter of through-hole is less than 8 interior diameter of step ring；The 3 bottom end outer diameter of gasket Less than 3 front end external diameter of gasket；The gasket 3 is connected between connector 21 and step ring 8；8 antetheca of step ring is butted on On the rear wall of gasket 3,21 rear wall of connector is butted on the antetheca of gasket 3.

Specifically, the seal groove 4 is 3 altogether, corresponding O-ring 5 is also 3.

Principle explanation: 3 bottom end outer diameter of gasket is less than 3 front end external diameter of gasket by the utility model, and whole outside is one Truncated conical shape, it is more light when being put into internal thread hole 11, and be more not easy if when taking out gasket 3, after convenient Continuous installation, specific 3 front end overall diameter of gasket are equal to the diameter of threaded hole 11；And 9 diameter of through-hole of gasket 3 is less than step ring 8 interior diameters, installation when, connector 21 screws extruding pad 3, the internal diameter front of step ring 8 can firmly be adjacent in it is 3 close Big envelope, sealing effect is good, and because 3 lateral surface of gasket is the design of frustum cone side, gasket 3 is rubber, when stress deformation There is space to be not easy excessive compression inserts 2；Using the design of O-ring 5, when making its 1 aging of tube body, tube body 1 and inserts 2 not leakiness Water, and using the design of snap ring 7 and card slot 6, after making 1 aging of tube body, inserts 2 is not easily to fall off；The connector 21 can be water Valve or tap or water pipe etc..
