Abstract

The utility model discloses a socket type fast connecting pipe fitting which comprises a pipe body and a nut which is connected with the pipe body by screw threads. The utility model is characterized in that a pressure ring is arranged between the pipe body and the nut; one end of the pressure ring stretches outside of the nut, the other end is provided with a convex platform and stuck in the nut. Part of the pressure ring outer surface which is in the nut shows a cone shape. A rigid clip which is matched with the cone shape surface of the pressure ring is provided within the pressure ring. The inside diameter of the clip shows a concave and convex tooth type. A clip ring is provided within the clip. The inner surface of the clip ring is a cone surface which is matched with the clip. An O - shaped sealing ring is also provided within the clip ring. The utility model is convenient and fast in installing and disassembling. The utility model not only overcomes the complicated working procedure of screw thread connection, but also overcomes the defect of the existing fast connector that the pressure bearing strength is low, and the connector is easy to become old. Therefore, the utility model is a novel fast connecting pipeline fitting which is worth of being popularized and applied.

Description

The spigot and socket type quickly jointed tubular workpieces

One, technical field

The utility model belongs to a kind of assembling pipe joint, relates in particular to a kind of pipeline fast-connection pipeline.

Two, background technique

Existing assembling pipe joint is threaded and is connected two kinds with non-threaded, the pipe fitting of metal material generally adopts threaded connector to connect, its deficiency is the manufacture cost height, install, dismantle complicated, and it is inapplicable to the composite metal-plastic pipe material, and the composite metal-plastic pipe material is day by day admitted by people, gradually with the substituted metal pipe fitting with tension, compressive strength height, light weight, specious, corrosion resistant, advantage such as cheap.The non-threaded link of the many employings of the connection of composite pipe fitting, the shortcoming that existing non-threaded pipe joint exists bearing strength inadequately pipe fitting to be come off mostly, and when connecting, must apply external force and realize sealing, tend to like this body is deformed, the plastics of extrusion are aging easily, aging stratification will take place in the composite metal-plastic pipe of heat processing and forming, cause the body seepage.

Three, summary of the invention

The purpose of this utility model is intended to overcome above-mentioned shortcoming, and a kind of installation, convenient disassembly are provided, the high and difficult aging spigot and socket type quickly jointed tubular workpieces of bearing strength.

For achieving the above object, the utility model adopts following solution: comprise body and the nut that is threaded with it, it is characterized in that: between body and nut, be provided with trim ring, one end of trim ring stretches out outside the nut, the other end is provided with boss and is stuck in the nut, and its outer surface of the part of trim ring in nut is tapered; Trim ring with interior be provided with rigidity and with the clamp of the conical surface of trim ring coupling, the internal diameter of clamp is erose; With the interior collar that is provided with, the internal surface of collar is the conical surface that is complementary with clamp at clamp; Collar is with the interior O RunddichtringO that is provided with.

Working procedure of the present utility model is: earlier nut is unlayed a little, the jointed tubular workpieces for the treatment of that then termination is provided with groove inserts in the joint, screws nut again and gets final product, and the shaggy tooth that nut screws on this quickly jointed tubular workpieces clamp of back just in time is stuck in the groove for the treatment of jointed tubular workpieces.During dismounting nut is unlayed a little, firmly presses the shaggy tooth that makes on the clamp to open outward inward trim ring then, can will treat jointed tubular workpieces extract.

Compared with prior art, the utlity model has following advantage:

1, because the utility model when installation and removal, only needs nut is unlayed a little, just can will treat that jointed tubular workpieces inserts or extracts, thereby finish installation and removal, so the utlity model has installation, convenient disassembly advantage efficiently.

2, since the utility model within it portion be provided with the band shaggy tooth clamp, treat jointed tubular workpieces insert in the joint and screw nut after shaggy tooth on the clamp just in time be stuck in and treat in the groove that the jointed tubular workpieces termination is provided with, it can not be deviate from, so the utlity model has the high advantage of bearing strength.

3, because the utility model need not apply external force when mounted, and body does not deform, so the utility model is difficult for wearing out.

Five, embodiment

As Fig. 1---shown in Figure 5, the nut 2 that the utility model comprises body 1 and is threaded with it, body 1 and nut 2 all adopt polymer material such as injection moulding manufacturings such as polypropylene, polyethylene; Be provided with the trim ring 5 that adopts the macromolecule engineering plastics to make between body 1 and nut 2, an end of trim ring 5 stretches out outside the nut 2, and the other end is provided with boss and is stuck in the nut 2, and its outer surface of the part of trim ring 5 in nut 2 is tapered; Trim ring 5 with interior be provided with manufacture with stainless steel material and with the clamp 6 of the conical surface of trim ring 5 coupling, the internal diameter of clamp 6 is erose; With the interior collar 4 that adopts the macromolecule engineering plastics to make that is provided with, the internal surface of collar 4 is the conical surface that is complementary with clamp 6 at clamp 6; With the interior O RunddichtringO 3 that is provided with, O RunddichtringO 3 is made by silica gel material at collar 4.

As shown in Figure 6, treat that the termination of jointed tubular workpieces 7 is provided with groove, the shaggy tooth that installs on back this quickly jointed tubular workpieces clamp 6 just in time is stuck in the groove for the treatment of jointed tubular workpieces 7, treats that therefore jointed tubular workpieces 7 can not deviate from.

Claims (1)
