Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further illustrated.
As shown in the figure, the utility model provides a kind of SEALING FITTING connecting the locking of Bamboo-shaped prestressed flat mouth plastic tube strap bolt, described SEALING FITTING 5 is relatively docked combination with a pair half flat mouthful of pipe 1 of specular by structure and is formed, and will dock the fastening combination in mating face by bolt fastener group 4.
Two big groove 1b that the inner ring of described each half flat mouthful of pipe 1 all has structure same intervals to arrange, two little groove 1a and sealing gasket groove 1c; Described two big groove 1b are separately positioned on the both sides of each half flat mouthful of pipe 1 mid-length; Described two little groove 1a are separately positioned on the outside of two big groove 1b; A sealing gasket groove 1c is respectively arranged with in the both sides of each big groove 1b.
Described two big groove 1b are wrapped in the outer rim of the first large flat mouth muscle 3b in Bamboo-shaped prestressed flat mouth plastic tube 3 end that SEALING FITTING 5 two ends connect respectively respectively; Described two little groove 1a are wrapped in the outer rim of the first little flat mouth muscle 3a in Bamboo-shaped prestressed flat mouth plastic tube 3 end that SEALING FITTING 5 two ends connect respectively respectively; Described sealing gasket groove 1c is corresponding with the little straight tube 3c position of first large flat mouth muscle 3b both sides, described Bamboo-shaped prestressed flat mouth plastic tube 3 end; In described sealing gasket groove 1c, flat mouth sealing gasket 2 is housed respectively.
The fastening docking mating face of described bolt fastener group 4 is two pairs of flanged surfaces, and described two pairs of flanged surfaces are axially protruded to respective outer rim along SEALING FITTING 5 respectively by the mating face, both sides of each half flat mouthful of pipe 1 to be formed.
Described bolt fastener group 4, after bolt 4a passes the bolt hole 1d of a pair half flat mouthful of pipe 1, is fitted on bolt 4a, by the fastening combination of described flanged surface of a pair half flat mouthful of pipe 1 by pad 4b and nut 4c.
Transverse sealing connecting groove 1g junction plane being respectively arranged with and being communicated with described sealing gasket groove 1c is docked at described a pair half flat mouthful of pipe 1.
Described flat mouth sealing gasket 2 comprises the longitudinal sealing pad 2a of multiple half flat mouthful of cast of vertical seal joint 5 axis and is parallel to SEALING FITTING 5 axially and be positioned at the lateral connection sealing gasket 2b at multiple longitudinal sealing pad 2a two ends; Described multiple longitudinal sealing pad 2a is separately positioned in the described sealing gasket groove 1c on described a pair half flat mouthful of pipe 1 inner ring; Described lateral connection sealing gasket 2b is separately positioned on described a pair half flat mouthful of pipe 1 and docks in the transverse sealing connecting groove 1g on junction plane.
In particular, as shown in Figure 1 and Figure 2, two pairs of flanged surfaces that positional symmetry structure is identical at the docking junction plane of a pair half flat mouthful of pipe 1 both sides, each side flange face of each half flat mouthful of pipe 1 is provided with two bolt hole 1d, bolt hole 1d position on a pair half flat mouthful of two pairs, pipe 1 both sides flanged surface is corresponding, be convenient to bolt 4a pass, by the pad 4b and nut 4c being fitted in bolt 4a end, a pair half flat mouthful of pipe 1 be locked.
As shown in the figure, two big groove 1b that a pair half flat mouthful of pipe 1 inner ring is arranged respectively are used for wrapping up in the outer rim of the first large flat mouth muscle 3b in Bamboo-shaped prestressed flat mouth plastic tube 3 end; Two little groove 1a that a pair half flat mouthful of pipe 1 inner ring is arranged respectively are wrapped in the outer rim of the first little flat mouth muscle 3a in Bamboo-shaped prestressed flat mouth plastic tube 3 end that pipe SEALING FITTING 5 two ends connect respectively respectively.
In the sealing gasket groove 1c of each big groove 1b left and right sides, be all provided with flat mouth sealing gasket 2, flat mouth sealing gasket 2 is connected as a single entity by multiple longitudinal sealing pad 2a and two lateral connection sealing gasket 2b to be put into respectively in described sealing gasket groove 1c with in transverse sealing connecting groove 1g.
