Abstract

The invention relates to a water pipe connector, and in particular relates to a quick connector of water pipes. The quick connector comprises a thread interface, a seal ring, a clamping ring, a conical claw, and a conical thread busing, wherein the connection comprise the following steps: successively placing the seal ring, the clamping ring and the conical claw in the thread interface, screwing on the conical thread busing, inserting a water pipe, and then screwing down the conical thread busing, thus completing the process of collection by means of the connector; the thread interface comprises a step I and a step II, the step I has a diameter corresponding to that of the water pipe, and the step II has a diameter corresponding to those of the seal ring, the clamping ring and the conical claw, and the conical claw is of a ring structure in an approximately conical shape; a clamping mouth is arranged at the annular side, clamping thorns are arranged in the ring; and a conical contact surface is arranged at the outer end. The quick connector is convenient and quick to install, and after installation, the water pipe has small possibility of bursting and has no water seepage phenomenon.

Description

A kind of rapid pipe joint

Technical field

The present invention relates to water pipe adapter, particularly a kind of rapid pipe joint of water pipe.

Background technique

In the process that water pipe is laid and installed, often to use various terminal, these joints will use special tool when installing mostly, use quite inconvenience, waste time and energy.Especially plastic tube is installed, bigger will the scrapping by stripped thread of exerting oneself, and too little will leaking firmly, some is after installation, since self hydraulic pressure, the phenomenon of can produce infiltration, leaking, and effect is undesirable.

Summary of the invention

The objective of the invention is to invent a kind of rapid pipe joint in order to overcome the defective that existing water pipe adapter is difficult for installing, being prone to explosion, infiltration.

The objective of the invention is to realize as follows: said a kind of rapid pipe joint; Comprise: threaded coupling, seal ring, pressure ring, taper pawl, thread taper cover; Said seal ring, pressure ring, taper pawl are put into threaded coupling successively; The thread taper of screwing on cover inserts water pipe, and the threaded together taper sheath can be accomplished connection again.

Described threaded coupling comprises step one and step two, and wherein, step one coincide with the water pipe diameter, and the diameter of step two and seal ring, pressure ring, taper pawl coincide.

Described taper pawl is a nearly conical annular structure, and wherein, a side of conical ring is provided with bayonet socket, is provided with the card thorn in the ring, and the outer end is made as conical contact face.

Good effect of the present invention is following: after connecting completion, the hydraulic pressure inner owing to water pipe is quite big, and common water pipe connects and can generation seep water; Even the phenomenon of explosion; And described rapid pipe joint has been owing to adopted the taper pawl, when hydraulic pressure produces thrust to water pipe, water pipe together with the taper pawl can and the thread taper cover between produce reaction force; Conical contact face above the reaction force compressing taper pawl dwindles bayonet socket, and what the card thorn can be tighter is pressed on the water pipe.It is easy to install and use, quick, and water pipe has the explosion of being difficult for, impermeable advantage after the installation.

Among the figure, 1, threaded coupling 2, seal ring 3, pressure ring 4, taper pawl 5, thread taper cover 11, step 1, step 2 41, bayonet socket 42, card thorn 43, conical contact face

Embodiment

As shown in Figure 1; Said a kind of rapid pipe joint; Comprise threaded coupling 1, seal ring 2, pressure ring 3, taper pawl 4, thread taper cover 5, saidly seal ring 2, pressure ring 3, taper pawl 4 are put into threaded coupling 1 successively, the thread taper of screwing on cover 5; Water pipe is inserted, and threaded together taper sheath 5 can be accomplished connection again.

As shown in Figure 2, described threaded coupling 1 comprises step 1 and step 2 12, and wherein, step 1 coincide with the water pipe diameter, and the diameter of step 2 12 and seal ring 2, pressure ring 3, taper pawl 4 coincide.

As shown in Figure 3, described taper pawl 4 is a nearly conical annular structure, and wherein, a side of conical ring is provided with bayonet socket 41, is provided with card thorn 42 in the ring, and the outer end is made as conical contact face 43.

When mounted; Water pipe is inserted by thread taper cover 5, during through taper pawl 4, can make taper pawl 4 produce outside expansionary force; Bayonet socket 41 above the taper pawl 4 will enlarge; Thereby water pipe is passed through easily, step one 11 places that water pipe arrives in the threaded coupling 1 through pressing plate 3, seal ring 2, threaded together taper sheath 5 can be accomplished connection again.

After connecting completion, the hydraulic pressure inner owing to water pipe is quite big, and common water pipe connects and can generation seep water; Even the phenomenon of explosion, and described rapid pipe joint is owing to having adopted taper pawl 4, when hydraulic pressure produces thrust to water pipe; Water pipe is together with producing reaction force between 4 meetings of taper pawl and the thread taper cover 5; Conical contact face 43 above the reaction force compressing taper pawl 4 dwindles bayonet socket 41, and tighter being pressed on the water pipe of card thorn 42 meetings effectively prevents infiltration and explosion.

Said threaded coupling, seal ring, pressure ring, taper pawl, thread taper cover and water pipe are a cover combination product, the standard piece setting.

Above-described specific embodiment only is a preferred implementation of the present invention; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention; Also can do some adjustment and improvement, these also should be regarded as belonging to protection scope of the present invention.
