Abstract

The utility model relates to a manual pipe joint, which comprises a connection body, a straining ring, a snap ring, a wedge ring and an O-shaped ring, wherein, the connection body is screwed with the straining ring, the conical surfaces of the snap ring and the wedge ring are mutually matched and are simultaneously sheathed out of a pipe wall. The snap ring and the wedge ring are open rings, the ring body is provided with an open slot, a V-shaped slot is formed between the connection body and the snap ring, and the O-shaped ring is clamped in the V-shaped slot. The utility model overcomes the disadvantages of poor connection reliability of pipe joints and easy slipping of the pipe from the joint under the function of external force or internal pressure in the prior art. The utility model has the advantages of simple structure, convenient installation and operation, good sealing performance and strong reliability with the pipes, and the utility model is suitable for the connection and installation of the pipes with various materials.

Description

Manual pipe joint

The utility model relates to a kind of manual pipe joint.

Existing manual pipe joint, all by pipe fitting, pipe fitting nut, seal ring, end sheet and stop ring constitutes, the external diameter of its retaining sheet and retaining ring is less than the internal diameter of pipe fitting nut, can not produce the function of adjusting by peace pipeline axis degree, under user mode, retaining ring when the outer surface of retaining sheet incision pipeline produces is in abundant swelling state, but owing to have the gap between retaining ring and pipe fitting nut, long-term swelling state can cause the retaining annular strain, the pressure of retaining sheet reduced, influenced the performance that retaining sheet clamps pipe fitting for a long time.Simultaneously, under the effect of external force or interior pressure, because that retaining sheet itself is cut the external diameter surface of pipeline is very few and can not further add to the pipeline Surface deformation and make deep cuts into, therefore, pipeline promptly comes off from joint.

The purpose of this utility model is the above-mentioned defective that overcomes prior art, thereby provides a kind of simple, easy for installation, and is reliable with being connected of pipeline, prevents the manual pipe joint of pipeline slippage.

The utility model comprises junctor, collar, snap ring, wedge ring and O type circle, junctor and collar bolt, and the mutual cone match of snap ring and wedge ring is socketed in outside the tube wall simultaneously, and snap ring and wedge ring are trip ring, do not have opening slot on the ring body.

Of the present utility model further is to form the V-type groove between snap ring and junctor, and O type circle is installed in the V-type groove.

Below in conjunction with drawings and Examples detailed content of the present utility model is described:

Fig. 1 is a structural representation of the present utility model;

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

Fig. 3 is the structural representation of snap ring;

Fig. 4 is the structural representation of wedge ring;

As shown in the figure, the utility model comprises junctor 1, collar 2, snap ring 3, wedge ring 4 and O type circle 5, junctor 1 and collar 2 bolts, snap ring 3 and wedge ring 4 mutual cone match and be socketed in outside the tube wall simultaneously, snap ring 3 and wedge ring 4 are trip ring, ring body is provided with opening slot 6,7, forms V-type groove 8 between snap ring 3 and the junctor 1, and O type circle 5 is installed in the V-type groove 8.Under user mode, when collar 2 is screwed in junctor 1, the wedge ring 4 internal diameter conical surfaces behind the contact snap ring 3 external diameter conical surfaces because the effect of opening slot 7, press close to the internal diameter and the end face adjustment of collar 2 rapidly, promoting snap ring 3 simultaneously moves to junctor 1 direction, force O type circle 5 in V-type groove 8, to be out of shape, to fill, be close to junctor 1 end face and pipeline external diameter, guarantee sealing and formation clamping force simultaneously pipeline.Wedging along with wedge ring 4 conical surfaces, because the effect of opening slot 6, the conical surface of snap ring 3 is regulated voluntarily with the outside dimension and the shape of pipe fitting, and produces clamping force, hold pipe fitting, when pipe fitting produced slippage under the effect of external force or interior pressure, snap ring moved to wedge ring 4 directions not under the drive of clamping force (frictional force), form bigger clamping force, balance each other with slippage power, thereby make difficult deformation that formation between member and the pipe fitting is firm, an integral body of favorable sealing property.

The utility model is by above-mentioned specific design, has simple in structurely, easy for installation, and sealing property is good, Connect reliable advantage, be suitable for being connected and installed of various material pipelines.

Claims
