Abstract
The utility model relates to a fast connecting structure for pipe fittings. The fast connecting structure for the pipe fittings comprises a plug part, a connector part, a sealing rubber ring and a U-shaped clamping piece, wherein a bell and spigot is arranged in the connector part, the plug part is inserted into the bell and spigot in the connector part, the sealing rubber ring is pressed between the bottom edge of the bell and spigot and the top edge of the plug part, the U-shaped clamping piece penetrates through a penetrating hole formed in the outer wall of the connector part and is clamped in an annular groove formed in the plug part. The fast connecting structure for the pipe fittings is suitable for the connection between metal pipe fittings or non-metal pipe fittings (including elbows, tee joints, valves and the like) and pipes, no power source is needed in the operation, the pipe fittings do not need to be heated, only a plug part of a pipe needs proper correction, the operation is simple, connecting is fast, the connecting part is attractive in appearance, and the pipe fittings can be reused. Therefore, the fast connecting structure for the pipe fittings is economical and environmental friendly.
Description
Technical field
The utility model relates to a kind of connection of pipe fitting, specifically a kind of rapid connecting structure of pipe fitting.
Background technique
Plastic tube adopts hot melt to connect with being connected of various plastic pipes mostly.The characteristics of this Placement be connect more firm, but the problem that exists includes: require once-through, can not revise, speed of application is slow, and is tight to temperature control requirement, needs the 220V power supply, not easy to operate at small space, the outward appearance of joint is attractive in appearance inadequately, and the retardance risk is arranged in the pipe, and scalds etc. easily in the operating process.Therefore, the hot melt of pipe fitting connects, and requires the operator to have suitable working experience.
The model utility content
The purpose of this utility model just provides a kind of rapid connecting structure of pipe fitting, connects the problems that exist to overcome hot melt, the mode that simplifies the operation, the connection of convenient various pipe fittings.
The utility model is achieved in that a kind of rapid connecting structure of pipe fitting, comprises intercalation part, joining part, O-ring seal and U-shaped card, is provided with joint socket in described joining part, and described intercalation part is plugged in the described joint socket in the described joining part; The end that described O-ring seal is squeezed in described joint socket along and the top of described intercalation part along between; Penetrate the jack hole of described U-shaped card from described joining part outer wall, be connected on the annular slot on the described intercalation part.
The internal diameter of the described joint socket in the described joining part is slightly larger than the external diameter of described intercalation part, and the end of described joint socket is along perpendicular with the axial section of described joining part.
There is chamfering on the top of described intercalation part along cylindrical.
Described O-ring seal is the plantation rubber ring that outer ring thickness is bigger than normal, inner ring thickness is less than normal.
The utility model is connected applicable to metal or nonmetal pipe fitting (comprising elbow, threeway, valve etc.) and tubing, operation need not power supply, need not heat pipe fitting, only need suitably revise the intercalation part of tubing and get final product, easy and simple to handle, connect fast, joint is attractive in appearance, pipe fitting is reusable, economical environment-protective.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of O-ring seal.
Fig. 3 is the structural representation of U-shaped card.
Embodiment
As Fig. 1-shown in Figure 3, the utility model comprises intercalation part 1, joining part 2, O-ring seal 3 and U-shaped card 4.Intercalation part 1 is straight length, and the cylindrical on its edge, top is shaped on chamfering, so that peg graft in joining part 2.Be shaped on a circle outer ring at intercalation part 1, form annular slot.Be provided with joint socket 5 in joining part 2, the internal diameter of joint socket is slightly larger than the external diameter of intercalation part 1, so that the grafting of intercalation part 1 cooperates.The end of joint socket 5, is along perpendicular with the axial section of joining part 2.U-shaped card 4 can be metalwork; O-ring seal 3 is plantation rubber rings that a kind of outer ring thickness is bigger than normal, inner ring thickness is less than normal.
When the pipe fitting that carries out the PP-R pipe connects, the intercalation part 1 of PP-R pipe is plugged in the joint socket 5 of joining part 2 of various pipe fittings and holds out against, the end that O-ring seal 3 is compressed in joint socket 5 along and the top of intercalation part 1 along between, and, because the existence in the chamfering slit of intercalation part 1 and the outer structure of thin O-ring seal in thick, make that the outer portion of O-ring seal 3 is extruded in the chamfering slit of intercalation part 1, sealing effect significantly improves.With penetrating the jack hole of U-shaped card 4 from joining part 2 outer walls, be connected on the annular slot on the intercalation part 1, intercalation part 1 is positioned in the joining part 2, thereby realizes being tightly connected reliably.After extracting U-shaped card 4, intercalation part 1 is namely separable with joining part 2, to realize repeated use or the joint adjustment of pipe fitting.
Claims (4)
1. a rapid connecting structure of pipe fitting is characterized in that, comprises intercalation part, joining part, O-ring seal and U-shaped card, is provided with joint socket in described joining part, and described intercalation part is plugged in the described joint socket in the described joining part; The end that described O-ring seal is squeezed in described joint socket along and the top of described intercalation part along between; Penetrate the jack hole of described U-shaped card from described joining part outer wall, be connected on the annular slot on the described intercalation part.
2. rapid connecting structure of pipe fitting according to claim 1 is characterized in that, the internal diameter of the described joint socket in the described joining part is slightly larger than the external diameter of described intercalation part, and the end of described joint socket is along perpendicular with the axial section of described joining part.
