Specific embodiment
With reference to the accompanying drawings of the specification and embodiment, specific embodiment of the utility model is described in further detail:
Referring to figs. 1 to a kind of steel-plastics composite pipe with interior solid ring shown in fig. 5, including skeleton 3 and three mould along steel
The interior firmware 4 of the circumferentially-spaced distribution of 2 inner wall of multiple tube；All 4 structures of interior firmware are identical, and per between any two in 120 degree
Angle；Interior firmware 4 includes U-shaped piece of 4a, arc panel 4c, elastic layer 4d and the adhesive layer that side in U-shaped piece of 4a opening is arranged in
Outer wall of the other side to be close to steel-plastics composite pipe 2 in 4e, U-shaped piece of 4a opening；Arc panel 4c, elastic layer 4d and adhesive layer 4e
Successively the spacing direction in U-shaped piece of 4a opening is superposed；The U-shaped piece of bottom 4a in all interior firmwares 4 be equipped with one it is convex
Block 4b；Skeleton 3 includes cylindrical piece 3a and three support bar 3b, and one end of all support bar 3b connects with a convex block 4b respectively
It connects, and the other end is connect with cylindrical piece 3a.
The end cross-sectional of all support bar 3b is prismatic structure；When skeleton 3 is in 2 inner wall of steel-plastics composite pipe,
Cylindrical piece 3a and the axis of the steel-plastics composite pipe 2 coincide, and support bar 3b is in 2 inner wall of steel-plastics composite pipe, and (i.e. plastics lined pipe 1 is interior
Wall) in when, when due in normal use, water flow can rapidly pass through, and support bar 3b is due to itself prismatic structure characteristic, side at this time
Side inclined-plane can reduce the resistance generated between water flow, guarantee the stabilization of support bar 3b, and then guarantee skeleton 3 and interior firmware 4
Monolithic stability.
The skeleton 3 further includes three firm 3c；All firm 3c are distributed in all supports in isosceles triangle
The outside of 3b, and the both ends of all firm 3c are fixedly connected with a convex block 4b respectively, at the center of all convex block 4b
Respectively three vertex of isosceles triangle, three firm 3c constitute isosceles three with two support bar 3b of respective position respectively
The medium of angular shape is open, also makes between guarantee plastics lined pipe 1 and steel-plastics composite pipe 2 in stable connection convenient for the process of water flow
Water flow can be normal through.
The end cross-sectional of the firm 3c is prismatic structure, consolidates a 3c due to itself prismatic structure characteristic, side is oblique
Face can reduce the resistance generated between water flow.
The concave surface of the arc panel 4c is fixedly connected with the opening inner wall of U-shaped piece of 4a, and elastic layer 4d includes rubber pad, rubber
Pad is sticked in the outer wall of arc panel 4c, and adhesive layer 4e is fixed at the outer surface of rubber pad, and interior firmware 4 is being placed into steel modeling
When in 2 inner wall of multiple tube (i.e. the inner wall of plastics lined pipe 1), adhesive layer 4e can be bonding with the inner wall of plastics lined pipe 1, guarantees that steel modeling is multiple
The stability closing pipe 2 and being connected between plastics lined pipe 1.
The arc panel 4c is provided with the intervention plate 5 to extend outwardly far from one end of U-shaped board；Intervention plate 5 is plastic material,
And its structure is half arc shape；The arc top outer surface of intervention plate 5 is sticked and has sealant 6, intervention plate 5 as preferentially enter to
In 2 inner wall of steel-plastics composite pipe (i.e. the inner wall of plastics lined pipe 1), then its plastic properties, can generate extrusion deformation and shrink, so when being situated between
It is subsequent that 1 inner wall of plastics lined pipe is contacted by adhesive layer 4e after entering plate 5 completely into 1 inner wall of plastics lined pipe, it generates and contacts and bond；It is close
Sealing 6 in use, water flow will not excessively flow into adhesive layer 4e, but to be obstructed by sealant 6 in steel-plastics composite pipe 2,
It is directly flowed through between three interior firmwares 4, not will cause and the adhesive surface structure of adhesive layer 4e is caused to impact, influenced it and use the longevity
Life.
Working principle: manually skeleton 3 and all interior firmwares 4 are put into steel-plastics composite pipe 2 (i.e. the inner wall of plastics lined pipe 1)
Afterwards, it (is inserted into from the nozzle of steel-plastics composite pipe 2), intervention plate 5 preferentially enters, itself plasticity generates deformation, then adhesive layer 4e
Into, and have portion retracts space by rubber layer, (while the rubber layer is also as the knot below protection adhesive layer 4e
Structure face prevents from being washed out structure by water flow, that is, cooperation sealant 6 forms lower right protection, and the other side is then by the opening of U-shaped piece of 4a
Slot bottom is protected), then the opening spacing of U-shaped piece of 4a opening is by the inner wall thickness summation of steel-plastics composite pipe 2 and plastics lined pipe 1
It wraps up, the side in U-shaped piece of 4a opening, which that is to say, is close to the outer wall of steel-plastics composite pipe 2, and the other side relies on adhesive layer 4e, plasticity
The inner wall of plastics lined pipe 1 is close to by the intervention plate 5 and sealant 6 of characteristic；Then in routine use, support bar 3b and firm 3c
Successive cooperation, it is firm whole using triangular support power, prevent the flow forces impact failure steel-plastics composite pipe 2 and lining at water source
The stability connected between modeling pipe 1；And illustrating, support bar 3b and a firm 3c are plastic material, meet the process of installation,
And the end of steel-plastics composite pipe 2 is provided with the lock 7 of tubular structure, using lock 7 that U-shaped piece of 4a is exposed in steel-plastics composite pipe
The part of 2 outer walls carries out press-down type package and locking.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model
Any restrictions out, thus it is any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent
Variation and modification, in the range of still falling within the technical solution of the utility model.
