Abstract

The utility model relates to a water pipe joint, especially a quick joint, which comprises a screw thread interface, a sealing ring, a pressing ring, a tapered pawl and a thread tapered sleeve. The sealing ring, the pressing ring and the tapered pawl are orderly arranged inside the screw thread interface. The screw thread tapered sleeve is screwed up and then a water pipe is inserted into the screw thread interface. Then the screw thread tapered sleeve is tightened so as to complete the connection. The screw thread interface comprises a step 1 and a step 2. The step 1 is matched with the diameter of the water pipe, while the step 2 is matched with the diameters of the sealing ring, the pressing ring and the tapered pawl. The tapered pawl adopts an approximate conical annular structure. One side of the annular structure is provided with a bayonet and a clamping stab is arranged inside the annular structure. The outer end of the quick joint is provided with a tapered contacting surface. The quick joint is convenient and quick in installation. After being installed with the quick joint, a water pipe does not easily burst and has no water seepage.

Description

Rapid pipe joint

Technical field

The utility model relates to water pipe adapter, particularly a kind of fast joint of waterpipe.

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

The purpose of the utility model realizes as follows: said 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.

The good effect of the utility model 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.

Embodiment

As shown in Figure 1; Said 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 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 the preferred implementation of the utility model; Should be understood that; For the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model principle, also can do some adjustment and improvement, these also should be regarded as belonging to the protection domain of the utility model.
