Technical field

The present invention is relevant for a kind of no flange and seamless bush that is used for smooth tubes, and it comprises: a locking device voluntarily that is connected with each pipe; And with a flexible folding part, its each end is locked on the terminal of a pipe and at this voluntarily in the locking device.This voluntarily locking device comprise: one has the housing of opening on every side, and with this folding edge partly of an internal edge cover cap, and it is clamped this pipe; And at least one is towards the peripheral groove of this pipe, and to hold one be the anchor member that stops with the hook, and this hook applies and is depressed into this pipe, and will be through assembling and clamped housing locking with it.This housing is formed by at least two peripheral portions.

Background technique

A kind of lining or similar device that is used for smooth tubes, it is known according to F.P. case FR 98 13 118.Relevant for background technique of the present invention, please refer to this case content.

Summary of the invention

The objective of the invention is to develop pattern is installed in one, and allow easier and realize the installation of lining easily.

For reaching this effect, the lining of relevant more than one forms that define of the present invention is characterized by, and each housing of this locking device comprises: enter rib in the district at it, be used for the terminal of overlapping this pipe of part; And one folding partly.This is folding partly to comprise: be provided with the internal surface of rib in its each terminal, with the outer surface that is provided with groove.These ribs are opposite trend with the fluctuating of groove, these both wherein one depression partly by a vertical plane corresponding to wherein another depression partly, and anti-as the same.

The rib of this housing allows this folding part is locked on this pipe with whole housing more easily and securely in the folding therewith partly combination of the groove of terminal of this rib, so that it generally speaking, this lining can more easily connect: two pipes; Or a device, the terminal of a valve for example, it stops by a pipe and another pipe; Or two devices, its terminal stops by a pipe.So can transmit the increase of haulage device weight and the increase of material simultaneously.

Another favorable characteristics according to the present invention, the summit of this rib protrude in folding in-profile partly, and are engaged on the pipe of sleeve.

Distance between the summit of this rib and groove summit produces a whole sinusoidal profile, and it is convenient and improve on terminal that is hooked on this smooth tubes by the clamping of this housing of this folding terminal partly.These ribs are inserted in the folding outer surface partly, and this housing summit with folding partly between produce linear the contact, this helps this and folding partly is hooked in the housing securely, and the fluctuating summit of this folding partly rib, is hooked on the surface of this smooth tubes securely.This housing ribs can so transmit clamping force the skeleton of folded part part so far effectively, and this similarly helps this folding part is hooked on this pipe.

For convenience this folding part is engaged on the terminal of this pipe slope around this inlet comprises.

If this hanging hook component be by each corresponding to half-two of annulus partly institute constitute, it will be easily convenient then being arranged at this lining especially clamping of this half housing on this anchor member and being arranged on this folding terminal partly.So realization can be when this assembly be closed, and itself is provided with by above-mentioned annulus to be used for the uneven of hook, and can avoids these two housings to slide.

This is same convenient begin that easily these two housings are arranged at that pipe is gone up and folding partly on, this is owing to half and half-annulus can be placed the groove of this housing, the terminal of half and half-annulus is shunk with respect to the mating face of each-half housing.

In this case, the clamping of these two housings can't owing to: this is positioned at the extension existence partly of the annulus between two and half housings, and holds too tight.

According to another embodiment, for the liquid conduits that is subjected to quite big pressure, then this folding each terminal is partly stopped by an annular soft pad, and these housings peripheral groove of respectively comprising a section is with corresponding to this annular soft pad for favourable.This helps this folding partly is hooked on the lining once again, and avoiding under the effect of the too strong compression shock of for example water hammer, this is folding partly can to break away from this lining.Vice versa, and under equal pressure, this allows for the same pole end pressure, and it is accurate that the size of this lining is decreased to the folding therewith position partly of housing.

The peripheral groove of these housings is suitable for the section of this annular soft pad, and these two sections equate significantly.The section of this groove is shorter than the section of annular soft pad a little, produces pinch effect in this way.

If the bottom of the peripheral groove of this housing comprises that one is inserted in the rib in the root and increases pressure thereon and therefore increase the pressure on this folding skeleton partly and increase folding pressure partly on this tube terminal, then be provided with in the situation of annular soft pad or root, can improve the situation of this clamping once again in this folding part.

If for tilting or the shape of concavity stitch, then can similarly make things convenient for this housing is closed, to avoid damaging this folding part in the terminal of the housing ribs of this composition plane position standard.

Below with reference to being described in more detail the present invention in the appended embodiment who is presented in graphic.

According to Fig. 1, the present invention is a kind of relevant no flange and seamless bush that is used to assemble two smooth tubes, or this equipment stops by these smooth tubes, and it is used for by fluid (liquid, steam, gas).

This lining is made of two automatic locking apparatus, and it presents a single part 11A and a folding part 2, and this partly stops by two symmetrical terminals 21.The purpose of these terminals is that each cooperates with automatic locking apparatus, and it separates by projection part 22, and allows to be absorbed in the symmetrical defective when assembling and the angle of the between centers of two terminals of these pipes.

This folding partly each terminal 21 of 2 is engaged on the terminal of this not shown pipe, and its integral body by a locking device 1 cover cap.The some of this locking device is clamped in this pipe with this folding terminal partly, and another part of this locking device directly is hooked in the terminal of this pipe.When this folding part is subjected to pulling force or thrust, is used to be locked in pipe at this folding this place partly, and can prevents that it from sliding with respect to pipe.This is folding partly by shrinking or extending and directly absorb these power.

Automatic locking apparatus 1 is formed by two housings 11, and in the big situation of this pipe diameter, its similarly also can by three housings or even more the big figure housing assemble each other.

These housings 11 have with respect to assembling axle XX symmetry or identical shaped, and this permission is limited to a housing with description.This housing 11 comes across in first version of Fig. 1, and in the first version 11A of Fig. 2.Each

housing

11,11A comprise a bent part, its significantly typical example stop by each limit of these

ears

12,12A as being the some of the circle of semicircle.These

ears

12,12A are assembled among two or several holes 13, the 13A, are used to allow bolt 3 pass through.This folding partly inside of side comprises zone 14,14A, and this zone is provided with several ribs 141,141A, for example three of dome point triangular sections or trapezoidal section ribs.These ribs are by an inclined surface or sunk molding 142,142A, with the accurate beginning in the position of composition plane.These stitches are used for when clamping housing 11, can not damage this folding part 2.

Be provided with rib in zone 14,14A part, this

housing

11,11A comprise groove 15, the 15A of rectangular section, are used to hold this folding partly root 23 of 2.The preferable section that is shorter than root a little of the section of this groove is used to strengthen this locking and pinch effect.

In the embodiment of this Fig. 1, when among the version 15A at Fig. 2, this peripheral groove 15 is contained in this root in the one simple rectangular section.This groove inside is equipped with the triangle or the trapezoidal section of domed end, is used for producing auxiliary holding power on this folding root 23 partly.

Groove part (it comprises or do not comprise root at this) in this folding terminal partly is provided with the peripheral groove 16, the 16A that are evident as triangular sections, it holds the anchor member 4 that this especially is two parts 41, as Fig. 3 perspective view presented.

The inside of these

grooves

16,16A is level and smooth, and in the situation according to the anchor member of annular two parts 41 of the present invention, each is partly significantly corresponding to a semicircle (length of this arc is preferable less than semicircle).This half anchor member 41 is arranged in the

peripheral groove

16,16A of

housing

11,11A, and forms the slide plate of bump 411 by its edge.When this housing was clamped in tube wall, this anchor member was hooked in this tube wall.

Fig. 4 demonstration is installed on above-mentioned lining 1,2 on the terminal of two pipes T1, T2.Left portion shows the lining in position, mating face standard of this two and half housing 11, and the outside that partly shows this lining on the right.

This figure especially shows the shape of this folding part 2 and its skeleton 24 with dotted line.This folding partly terminal of 2 clamps between these ribs 141 of the outer surface of pipe T1 and housing 11.These ribs 141 compress this on its skeleton 24 with under the material of folding part, as the displacement of skeleton in the thickness that herewith is presented at this folding partly wall.This figure also show with this anchor member 4 be hooked in this pipe T1 terminal in.

Fig. 5 is this folding partly axial cross-sectional view of 2 of lining, and its demonstration is provided with the structure of this lining, and it has the aspect of skeleton 24 and is integrated in the monoblock of material of this lining.Position in each terminal is accurate, be used herein in the part of overlapping this pipe partly.This folding part 2 presents: be provided with the outer surface of groove 211, be provided with the internal surface in the zone of rib 212 with comprising this.These ribs form bump with respect to the in-profile 213 of this folding partly terminal 21 of 2.

This folding partly inlet of 2 also is provided with slope 215, and it conveniently is engaged on this pipe, and allows one to be fit to very much this folding partly size of 2 interior zones, makes uneven on the outer surface of time institute's connecting pipe with compensation at it.

This folding partly shape of terminal is presented among Fig. 8 A severally with magnification ratio in this special case.This presents this folding partly terminal 21B of 2B: the simple variant of no root folded part part.Yet, no matter in the housing of this automatic locking apparatus, whether there is this root groove of root therewith, this is all identical in different embodiments with the structure that these ribs, housing and tube wall cooperate.This figure shows the distance between these grooves 211B and these ribs 212B: each time of groove is corresponding to the summit of a rib, this rib gives whole sinusoidal profile, and when its integral body is clamped, helping simultaneously: this housing is hooked on this folding part, and this folding part is hooked on the pipe.

According to Fig. 5, this is folding partly 2 to stop by the root 23 of rectangular section.

This is folding partly 2 with respect to the axle XX of this assembling and asymmetric, but be symmetry with respect to midplane PM: these folding partly two terminals 21 of 2 are identical.Therefore, not distinctly explanation.

Fig. 6 shows an alternate embodiment of this lining, and it is relevant for the shape of groove 15A, and this groove holds this folding partly root 23 of 2.The housing 11A of this lining is the housing of the lining of Fig. 2.This groove 15A inside is provided with rib 151A.This groove is exaggerated so that have the identical section surface of ear of the housing 12 of folding part 2 therewith significantly.This rib will be limited to the root distortion in the groove, and help simultaneously root and its clamp hook are hung on the pipe.

Fig. 7 shows another embodiment according to lining of the present invention.The more previously mentioned lining of this lining is simpler, because these housings 11B does not comprise the groove that is used for this folding root partly, and this folding partly 2B does not comprise root.This partly folding terminal 21B is the right.These other assemblies are identical with previous illustrated person among this embodiment, and have the same reference number that this finishes by a suffix speech B.Therefore, no longer repeat once explanation about it.

Fig. 8 shows that this does not have the shape of the folding part of root.This partly folding thin A of portion is presented among Fig. 8 A with magnification ratio.This details drawing highlights outer surface and the depression of internal surface and the distance between projection of emphasizing this folding terminal partly: this groove 211B that is implemented in the outer surface is the same level that is arranged in the summit of these ribs 212B, and these ribs give a whole sinusoidal profile.

This figure highlights equally and emphasizes to exceed distance (d) with respect to these ribs 212B summit of this folding partly in-profile 213B of 2B.

The structure of this folding partly terminal 21B of 2B and the structure identical (Fig. 5) of folding part 2 with root.

The above only is preferred embodiment of the present invention, and it only is used for purpose of illustration but not in order to the content of restriction the present invention and claim; Every other changes or modifies not departing from the equivalence done under disclosed spirit and the scope, all should be included in the scope of claim of the following stated.
