Abstract

The utility model discloses an aluminum-plastic compound pipe hole inserting type joint. The aluminum-plastic compound pipe hole inserting type joint is mainly composed of a joint body 1, a nut 2, a clamping ring 3, a sealing ring 4, and a pipe material 5. The joint body 1, the sealing ring 4, the clamping ring 3, and the nut 2 are orderly installed on the pipe material 5 which is connected. The aluminum-plastic compound pipe hole inserting type joint is characterized in that two outer conical surfaces of the clamping ring 3 are respectively matched with the inner conical surface on the joint body 1 and the inner conical surface of the nut 2. At least two annular grooves for installing the sealing ring 4 are arranged on the joint body 1. An outer circle of the sealing ring 4 is a conical surface. The integral circumference of the clamping ring 3 is provided with a notch, and a convex rib claw is arranged on the inner surface of the clamping ring 3. The aluminum-plastic compound pipe hole inserting type joint is adopted, the pipe material can be effectively and tightly clamped, and the aluminum-plastic compound pipe hole inserting type joint has good sealing effect.

Description

A kind of plastic-aluminum combined pore plugging joint
The utility model relates to the pipe fitting field, relates in particular to the link of aluminium-plastic composite pipe or overall plastic tubing.
The pipe joint of present domestic use as shown in Figure 1, the cross section of its collar 3 is common trapezoidal, the cross section of seal ring 4 is an ordinary rectangular, and a seal ring is housed only, can not make full use of the elasticity of rubber, especially collar 3 and seal ring 4 can not get effective coupling, and therefore the effect of sealing is undesirable, the poor reliability of chucking tubing.
The purpose of this utility model provides a kind of joint that tightens tubing and all better aluminium-plastic composite pipe of sealing effect or overall plastic tubing.
The purpose of this utility model is achieved through the following technical solutions:
A kind of plastic-aluminum combined pore plugging joint, mainly by fittings body, nut, collar, seal ring and tubing are formed, correspondingly on fittings body and the nut be provided with outer internal thread, fittings body, seal ring, collar, nut is installed on the connected tubing successively, on described fittings body, be provided with and be convenient to tubing male cone (strobilus masculinus) that inserts and the annular groove that seal ring is installed, also be provided with the end face hole slot that inserts for tubing on it, be provided with inner conical surface at the hole slot mouth, described nut is provided with inner conical surface, the cross section of described collar is trapezoidal, two male cone (strobilus masculinus)s that it is characterized in that described collar respectively with fittings body on inner conical surface and the inner conical surface of nut match, described fittings body is provided with at least two annular grooves that seal ring is installed, the cylindrical of described seal ring is a conical surface, and its whole circumference of described collar has breach, and its internal surface is provided with the muscle pawl of projection.
Above-mentioned plastic-aluminum combined pore plugging joint, its characteristics are that the tapering of the inner conical surface of two male cone (strobilus masculinus)s of described collar and fittings body, nut is 30-60 °.
Above-mentioned plastic-aluminum combined pore plugging joint, its characteristics are that the tapering of described its conical surface of seal ring is 3-15 °.
Above-mentioned plastic-aluminum combined pore plugging joint, its characteristics are that the wall thickness of described collar is 0.5-4mm, and the muscle pawl of the projection on the described collar has three.
Above-mentioned plastic-aluminum combined pore plugging joint, its characteristics are that described fittings body can be the elbow that has angle.
Above-mentioned plastic-aluminum combined pore plugging joint, its characteristics are that the material of described fittings body is copper, plastics or moulds for metal covering internal layer lining that described sealing ring material is nitrile butadiene rubber or silicone rubber, and described collar material is copper or stainless steel.
After a kind of plastic-aluminum combined pore plugging joint that the utility model provides adopts such scheme, the effect of chucking tubing and sealing improves greatly, pipes at two ends is separately achieved a butt joint, make the liquid or the gas that flow through tubing reach sealing simultaneously, and do not contact ferrous materials, avoid the ducted water of the surface pollution that gets rusty or other liquid of invar iron material.
Further specify embodiment of the present utility model below in conjunction with Figure of description.
Fig. 1 is the joint structure schematic representation of prior art
Fig. 2 is a kind of plastic-aluminum combined pore plugging joint structural representation of the utility model
Fig. 3 is a kind of plastic-aluminum combined pore plugging joint assembly process figure of the utility model
In Fig. 2 and Fig. 3, a kind of plastic-aluminum combined pore plugging joint of the utility model mainly is made up of fittings body 1, nut 2, collar 3, seal ring 4 and tubing 5.Fittings body 1 is provided with outside thread, nut 2 is provided with corresponding internal thread, fittings body 1 is provided with two male cone (strobilus masculinus)s being convenient to tubing 5 insertions and two annular grooves that two seal rings 4 are installed, also be provided with the end face hole slot that inserts for tubing 5 on it, be provided with 30-60 ° inner conical surface at the hole slot mouth, be provided with 30-60 ° inner conical surface at the tapped hole afterbody of nut 2, and whole circumference has the cross section of breach is that the tapering of the male cone (strobilus masculinus) at trapezoidal collar 3 its two ends is 30-60 °, and respectively with fittings body 1, the inner conical surface of nut 2 matches, the wall thickness of collar 3 is 0.5-4mm, its internal surface is provided with the muscle pawl of three projectioies, the cylindrical of two seal rings is conical surfaces, and tapering is 3-15 °.
