Abstract

A quick coupling of a claw-type plastic hose is disclosed, comprising a coupling body and a compressing sleeve, the compressing sleeve is sleeved outside of the coupling body in a vertically-moving manner, the upper end of the coupling body comprises a hollow cylinder and a claw, outer diameter of the hollow cylinder is smaller than that of the coupling body, the claw is positioned outside of the hollow cylinder, outer diameter of the claw is larger than that of the hollow cylinder, and a hollow cavity for accommodating the plastic hose is arranged between the claw and the hollow cylinder. The invention provides a quick coupling of the claw-type plastic hose having simple structure, convenient installation and firm connection.

Description

Quick coupling of claw-type plastic hose

Technical field

The present invention relates to a kind of plastic tube connection set.

Background technique

What have plastic flexible pipe now is connected with two kinds, and the one, bonding connection, the 2nd, union connects.The tradition union generally comprises outside thread head, gland nut and seal washer etc.Chinese patent 96236340.5 has been introduced a kind of plastic flexible pipe SEALING FITTING, is the joint that a kind ofly is threaded, the conical surface compresses sealing.Chinese patent 200710026771.8 has been introduced a kind of anti-loose, strong SEALING FITTING, is the joint that a kind ofly is threaded, the plastic cement seal ring compresses sealing, and the shortcoming of this class joint is that part is many, and installation steps are loaded down with trivial details; It is not firm to connect, and easily comes off.

Summary of the invention

For the complex structure that overcomes existing plastic flexible pipe connecting head, trouble be installed, connect illusive deficiency, the invention provides a kind of simple in structure, easy for installation, connect firm quick coupling of claw-type plastic hose.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of quick coupling of claw-type plastic hose, comprise joint body and clamping sleeve, described clamping sleeve can be sleeved on outside the described joint body up or down, the upper end of described joint body comprises hollow cylinder and claw, the external diameter of described hollow cylinder is littler than the external diameter of described joint body, it is external that described claw is positioned at described hollow cylinder, and the external diameter of described claw is bigger than the external diameter of described hollow cylinder, is the cavity that holds plastic flexible pipe between described claw and the described hollow cylinder.

Further, described claw comprises at least three dops, and each dop is spacedly distributed on circumference.

Further again, described claw comprises three dops, and three dop space 120 degree are distributed on the circumference.

Certainly, claw also can be two dops, four dops or more a plurality of dop.

Described joint body outside is provided with outside thread, and the inwall of described clamping sleeve is provided with the internal thread with described outside thread interlock.

Technical conceive of the present invention is: after plastic flexible pipe packed into hollow cylinder, clamping sleeve screwed on to the direction shown in the arrow, and three claws are extruded, and plastic flexible pipe is pressed on the outer wall of hollow cylinder simultaneously, reach connection, anti-loose and the sealing purpose.

Beneficial effect of the present invention mainly shows: simple in structure, easy for installation, connect firm.

Description of drawings

Fig. 1 is the overall structure figure of quick coupling of claw-type plastic hose of the present invention;

Fig. 2 is the joint body structural drawing;

Fig. 3 is the clamping sleeve sectional view.

Embodiment

Below in conjunction with accompanying drawing the present invention is further described.

With reference to Fig. 1~Fig. 3, a kind of quick coupling of claw-type plastic hose, comprise joint body 1 and clamping sleeve 2, described clamping sleeve 2 can be sleeved on outside the described joint body 1 up or down, the upper end of described joint body comprises hollow cylinder 4 and claw, the external diameter of described hollow cylinder 4 is littler than the external diameter of described joint body 1, described claw is positioned at outside the described hollow cylinder 4, the external diameter of described claw is bigger than the external diameter of described hollow cylinder 4, is the cavity that holds plastic flexible pipe 3 between described claw and the described hollow cylinder 4.

Described claw comprises at least three dops, and each dop is spacedly distributed on circumference.Described claw comprises three dop 5a, 5b, 5c, and three dop 5a, 5b, 5c space 120 degree are distributed on the circumference.Certainly, claw also can be two dops, four dops or more a plurality of dop.

Described joint body 1 outside is provided with outside thread, and the inwall of described clamping sleeve 2 is provided with the internal thread with described outside thread interlock.

As shown in Figure 1, clamping sleeve 2 rotation sets advance joint body 1 on earth, and three claw 5a, 5b, 5c are in relaxation state.After the port of plastic flexible pipe 3 packs into hollow cylinder 4, clamping sleeve 2 screws on to the direction shown in the arrow, and three claw 5a, 5b, 5c are extruded, and plastic flexible pipe 3 is pressed on the hollow cylinder 4 simultaneously, finish the connecting moves of plastic flexible pipe, reach purpose anti-loose and sealing simultaneously.

Claims (4)
