Embodiment
Following embodiment illustrates elastic pipeline closeouts of the present utility model in conjunction with the accompanying drawings without limitation.Those skilled in the art; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification, so all technical schemes that are equal to also belong to category of the present utility model, its scope of patent protection is limited by the application's claims.
Present embodiment illustrates of the present utility model preferred embodiment a kind of, a kind of specifically circular elastic pipeline closeouts.
Referring to Fig. 1, Fig. 3, the elastic pipeline closeouts comprises outer plate 1, clip plate 2, bolt 3, nut 4, elastomer 5.Outer plate 1, clip plate 2 constitute by 2 semi-annular shape steel metallic plates, and both are complementary at size, and wherein outer plate is slightly larger than clip plate.The shape of outer plate 1, clip plate 2, elastomer 5, size should be complementary with the internal diameter of cable duct 6, particularly, the external diameter of outer plate 1 should be slightly larger than internal diameter of the pipeline, clip plate 2, elastomer 5 external diameters should be slightly less than internal diameter of the pipeline, and elastomeric internal diameter should be slightly larger than the external diameter from its middle cable 7 that passes.In the present embodiment, the external diameter of outer plate 1 is 15cm, the about 7cm of internal diameter; The external diameter of clip plate 2 is 13cm, the about 7cm of internal diameter.For guaranteeing the intensity of inside and outside pressing plate, its thickness is 2mm.
Referring to Fig. 3, have 8 through holes at outer plate 1, clip plate 2, elastomer equably on the 5 corresponding positions, wherein, the through hole of clip plate 2 is square through holes.Pass through hole with bolt respectively outer plate 1, clip plate 2, elastomer 5 are coupled together, these bolts are towards same direction, and wherein nut is towards clip plate.Referring to Fig. 7 and Fig. 8, preferably, the type of bolt is round end side's body bolt, and it comprises round end nut 31, square body bolt ridge 32, external screw thread 33.Side's body bolt ridge 32 can be short as shown in Figure 7, between square body bolt ridge 32 and external screw thread 33 one section smooth double-screw bolt is arranged; Also can be as shown in Figure 8, square body bolt ridge 32 is long.Used bolt in the present embodiment as Fig. 6.Because the through hole of opening at clip plate 28 is square through holes, the bolt ridge of its aperture and round end side's body bolt is complementary.
Comparison diagram 1, Fig. 2.During use, outer plate 1, clip plate 2 are placed the both sides of elastomer 5 respectively, the position of aligned through holes is passed through hole with bolt they is coupled together.Because the through hole 8 of clip plate is square, the bolt ridge of bolt also is square, and their shape, size are complementary, and when bolt passed elastomer, bolt was fixed by clip plate.Therefore, when outer plate one side fastening nut, bolt can be along with rotation, convenient working.
During installation, semi-annular shape clip plate, elastomer, outer plate are installed one by one, cable 7 passes from the centre of circular closeouts, and the outer that outer plate is outstanding and the cross section of cable duct 6 fit.Fastening nut 4, inside and outside pressing plate is stressed to be made elastomer radially deformation to a certain degree occur and expands.Referring to Fig. 2, elastomer 15 external diameters of expansion can increase and press to inner-walls of duct, and the internal diameter of elastomer 15 can dwindle and press to the outer wall of circuit pipe on the other hand, plays the effect of closed conduit by this expansion.
The utility model good airproof performance.It has overcome the conventional pipelines closeouts and has made and lack flexible shortcoming owing to hard and crisp materials such as adopting cement.The elastic pipeline closeouts that the utility model proposes is behind fastening nut, thereby the effect of closed conduit is played in the elastomer expansion.And when producing vibration when the cable energising, this closeouts can not damaged because of vibration owing to itself having elasticity, can also absorb the energy of vibration, the protection pipeline.
The utility model is simple in structure, no matter be outer, clip plate or in the middle of elastomer, its mould process is all very simple; And bolt, nut all use standard component, need not painstakingly make.
The elastic pipeline closeouts of present embodiment also comprises is located at the middle cable stopple 9 of circular closeouts.
Referring to Fig. 4, the outer plate 1 of the pipe plugging spare of present embodiment, clip plate 2, elastomer 5 are with reference to embodiment 1, by 2 semicircular ring formations, in addition, the pipe plugging spare of present embodiment also comprises a cable stopple 9, its adopts the elastomeric material the same with elastomer 5 to make, and its shape, big or small and elastomer 5 internal diameters are complementary.The inside and outside both sides of---for example in the present embodiment, the internal diameter of elastomer 5 is 6.5cm, and the external diameter of cable stopple 9 is slightly less than the internal diameter of elastomer 5, about 6cm---cable stopple are not provided with pressing plate for the less situation of stopple diameter.Have a square through hole at the stopple middle part, and pass this square through hole with the round end side's body bolt as Fig. 7, the shape of square through hole, size and round end side's body bolt are complementary.During installation, semi-annular shape clip plate, elastomer, outer plate are installed one by one, and the outer that outer plate is given prominence to and the cross section of cable duct 6 fit, set up cable stopple 9 at mid portion again, tightening all nuts makes elastomer 5, cable stopple 9 radially deformation take place and expand, stopple pushes the internal diameter of circular elastomer 5, plays the effect of sealing.
Because underground piping has a large amount of pores, some pore can block up with the elastic pipeline closeouts that comprises cable stopple 9 of present embodiment when not using, and guarantees close property of liquid and air-tightness in the pipeline, guarantees installation security.The design and implementation example 1 of stopple is identical, and structure is very simple.Adopt the pipe plugging spare of present embodiment can be conveniently used in pipeline that cable passes through or idle pipeline, adaptability is stronger.
Present embodiment is a kind of distortion of embodiment 2, specifically is a kind of discoid elastic pipeline closeouts.
With reference to Fig. 5, Fig. 6, outer plate 1, clip plate 2 are circular steel metallic plates, and elastomer also is circular, and their size, shape are complementary, and wherein the slightly larger in diameter of outer plate is in elastomer.In the present embodiment, the diameter of outer plate 1 is 15cm, and the diameter of clip plate 2 is 13cm; The diameter of elastomer 5 is 13.5cm, the about 5cm of thickness.Outer plate, clip plate, elastomer all are discoid.Even 10 through holes that distribute in outer plate, clip plate, elastomer, other has a through hole to be located at position intermediate, and wherein, the through hole of clip plate is a square through hole.Pass through hole and outer plate, clip plate and elastomer are coupled together with as shown in Figure 7 round end side's body bolt.
For obsolete pore at ordinary times, can be with the closeouts of present embodiment stifled on.During use, the outer that outer plate is outstanding and the cross section of cable duct wall 6 fit, and tighten each nut rich blocking piece is expanded, and play the effect of sealing.
