Abstract

The invention discloses a pipe joint device pushed in cooperation, the pipe joint device comprises a double surface opening clamping ring used for joining with a body and a cap element. The cap element fixes the cap on the clamping and/or the body.

Description

The pipe joint of push fit

Technical field

The present invention relates to a kind of clamping ring that is used for the piping erection purpose, especially for the clamping ring of the pipe joint of push fit.

Background technique

The clamping ring that is used for the piping erection purpose comprises tooth or pawl, and this tooth or pawl be towards interior, and the surface of the pipe that is used for nipping, and pipe is pulled out from joint preventing, said clamping ring is connected with joint.

Clamping ring can be two-sided, all has tooth at two ends, and clamping ring can also comprise trip ring or complete ring.

The clamping ring that the purpose of this invention is to provide a kind of open double-faced is compared with the clamping ring of existing technology, and this open double-faced clamping ring provides a plurality of advantages at manufacture cost, practicability and aspect of performance.

Summary of the invention

According to the present invention, the pipe connector of push fit comprises the clamping ring of open double-faced, is used for engaging with body and cap element, and this cap element is used for releasedly cap being fixed on clamping ring and/or body.

Preferably, clamping ring comprises the trip ring element, and this trip ring element has first or pipe receiving terminal and second or the body engagement end, and first end comprises one group of radially inside tooth, and second end comprises the radial teeth of one group of shorter length, and they leave body towards interior.Tooth at second end is positioned at apart from this end intended distance place.

Body comprises the open ended passage that extends through; Each end is used for receiving tube end therein, and each end comprises exterior circumferential flange, and this exterior circumferential flange limits the end sections of body; This end sections is included in the peripheral groove between said end and the flange, is used for engaging with clamping ring; The recess that the inside of body comprises against the convex shoulder or the similar structure of the end of the pipe that is received and is used to shelve O shape ring.

In a preferred form, peripheral groove radially inwardly towards the sloped-end of body, ends at the right angle rear wall, thereby forms the sectional shape of general triangular.

In a kind of form of the present invention; Cap can be fixed on the body releasedly, and body comprises that around the isolated one or more bumps of its periphery said bump preferably surpasses peripheral groove than short distance; Cap comprises respective window or otch, is used to receive bump.In a preferred form, cap comprises contiguous each otch or the conduit that is communicated with each otch, and the internal diameter of this conduit is bigger than the internal diameter of cap.This makes cap to be pulled to above the bump, and can not engage with them.Window or otch are positioned near the conduit, and can stretch into very short distance in the conduit, so that allow the cap rotation and make bump engage with window, so that cap is locked on the body.Realize unlocking through rotating in opposite direction.

In use, at first cap is slid on the pipe that will connect.Clamping ring is pushed on the body, and tooth engages with peripheral groove simultaneously.Then, with tube end promote through first end of clamping ring with inner convex shoulder against.Then, cap is shifted onto above the clamping ring, and rotated to locked position, in this locked position, window engages with bump on the pipe fitting body.

In optional form of the present invention, cap is locked on the clamping ring, rather than is locked on the body of joint.

Through cap and clamping ring are locked together, formed pipe joint has obvious augmented performance, and this needs for larger-diameter pipe and their joint.

In this form of the present invention, clamping ring comprises and is used for one or more structures of engaging releasedly with the complementary structure of cap element.These structure optimization ground comprise one or more teeth of second group, said tooth outward, rather than towards interior.The tooth of these outwards engages with window or otch in the cap, with above-mentioned similar.

The assembling of cap for ease, said cap comprises a plurality of conduits, the diameter of these conduits and cap has bigger internal diameter.This makes cap can be pulled to above the tooth of outward, and can not engage with them.Window or otch are positioned near the conduit, and it is interior than short distance to stretch into conduit, so that allow the cap rotation and make tooth engage with window, thereby cap are locked on the clamping ring.Realize unlocking through rotating in opposite direction.

In use, at first cap is slid on the pipe that will connect.Clamping ring is pushed on the body, and tooth engages with peripheral groove.Then, with tube end promote through clamping ring first end and with inner convex shoulder against.Then, again cap is shifted onto above the clamping ring, and rotated to locked position.

Through making cap be locked on the clamping ring, larger-diameter pipe joint can successfully bear obviously bigger pressure.

Embodiment

In the accompanying drawings, the pipe joint of push fit comprises open double-faced clamping ring 10, is used for that 14 places engage with

pipe joint body

12 and 18 place's receiving tube (not shown) and the caps 16 in the end in the end.

Body 12 comprises open ended passage 20, is used at each end receiving tube (not shown).Externally, body comprises: leg-of-mutton peripheral groove 22 is used to receive the tooth of clamping ring; And bump 24, this bump engages with cap, so that cap is locked on the body of pipe fitting.In inside, circumferential notches 26 is arranged for shelves O shape ring, also is provided with convex shoulder 28, and the end of the pipe of insertion is against convex shoulder 28.

Clamping ring has towards interior radial teeth 32 at its pipe reception 18 places, end.In addition, at 14 places, body engagement end short tooth is provided, tooth pitch that should be short is very short from the distance of this body engagement end.In the form of Fig. 1 to 4, all towards interior, and direction is opposite with tooth 32 at 36 places for teeth.

Cap element 16 comprises cap, and this cap has opening 40 at the top, be used to receive the pipe that passes.The side of cap comprises and is used for four windows 42 engaging with bump 24.Also be provided with four conduits 44, the internal diameter of these four conduits is bigger than cap itself, and this makes cap on the bump 24 of protrusion, to slide.In case be in the position shown in Fig. 3, cap is rotated, makes bump engage, and cap is locked on the body 12 of pipe fitting with window 42.This locked position has been shown in Fig. 4.

Introduce the optional form of the joint shown in Fig. 5 to 8 below, can know that in the form of Fig. 1 to 4, cap can be fixed on the body of joint releasedly, and in this form, cap can be fixed on releasedly on the clamping ring 10.Replace bump, body 12 has peripheral flange 25.

Therefore, also be provided with the tooth 38 of four outwards, be used for engaging with cap element 16 with releasable engagement mode.These teeth are towards the direction opposite with tooth 32.
