Abstract
The utility model discloses a kind of bell and spigot joint, is made up of tool joint pin and female joint, and the madial wall of female joint arranges Stamping Steel Ribbon, and in the formation warping part, end of Stamping Steel Ribbon, warping part is towards water inlet direction; Tool joint pin is inserted in female joint, and tool joint pin insertion end is formed with tapering, and Stamping Steel Ribbon is close on the insertion end outer wall of tapering.The utility model convenience quick for installation, and hydraulic pressure is larger and encapsulation is better.
Description
Technical field
The utility model relates to a kind of bell and spigot joint, and it is applicable to pipeline and connects.
Background technique
PVC entwining tube is widely used in municipal drainage, blowdown, flood discharge and agricultural irrigation diversion, in prior art, connection between PVC entwining tube is generally pyrocondensation belt and connects, glass fibre reinforced plastics Harvard formula connects, epoxy resin is embraced liner outward and is connected and the connection of stainless steel locking hood type, but the defect of described Placement is:
Install inconvenience, complex process, the installation connect hours is long, poor stability, pipeline junction ring stiffness does not all reach designing requirement, and the joint between pipeline easily disconnects, flattens, and cause and leak, and leak and easily cause Subgrade Subsidence, affect pipework quality.
In view of this, the present inventor develops a kind of bell and spigot joint, and to overcome described defect, this case produces thus.
Model utility content
The purpose of this utility model is to provide a kind of bell and spigot joint, its convenience quick for installation, and hydraulic pressure is larger and encapsulation is better.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of bell and spigot joint, is made up of tool joint pin and female joint, the madial wall of female joint arranges Stamping Steel Ribbon, and in the formation warping part, end of Stamping Steel Ribbon, warping part is towards water inlet direction; Tool joint pin is inserted in female joint, and tool joint pin insertion end is formed with tapering, and Stamping Steel Ribbon is close on the insertion end outer wall of tapering.
Further, the madial wall that described Stamping Steel Ribbon is arranged on female joint forms assembly department, and the thickness of Stamping Steel Ribbon is thinning gradually to warping part by assembly department.
Further, described Stamping Steel Ribbon comprises back side and upstream face, and in upstream face and formation warping part, back side joint, back side is set to arc shaped surface, and upstream face is set to arc shaped surface or for plane.
Further, the madial wall of described female joint is formed and installs groove, described Stamping Steel Ribbon is arranged on to be installed in groove.
After adopting such scheme, the utility model in use, tool joint pin and female joint connecting tube respectively, tool joint pin is inserted in female joint, tool joint pin insertion end is formed with tapering, Stamping Steel Ribbon is close on the insertion end outer wall of tapering, and in the formation warping part, end of Stamping Steel Ribbon, warping part is towards water inlet direction.Therefore, when having current to pass through in the duct, the pressure extrusion Stamping Steel Ribbon warping part of current, makes it that resiliently deformable occur, and Stamping Steel Ribbon warping part is close to tool joint pin to be had on the insertion end outer wall of tapering, play sealing process, and when hydraulic pressure is larger, the elastic strain that Stamping Steel Ribbon warping part occurs is larger, Stamping Steel Ribbon warping part and tool joint pin have the insertion end outer wall of tapering to fit tightr, and encapsulation is better.
Meanwhile, the utility model is made up of tool joint pin and female joint, and structure is simple, and convenience quick for installation, also can install without the need to professional workforce.

Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
Consult shown in Fig. 1 to Fig. 4, a kind of bell and spigot joint that the utility model discloses, be made up of tool joint pin 1 and female joint 2.
The madial wall of female joint 2 arranges Stamping Steel Ribbon 3, and Stamping Steel Ribbon 3 is generally rubber strip, in the present embodiment, the madial wall of described female joint 2 is formed and installs groove 21, and described Stamping Steel Ribbon 3 is arranged on to be installed in groove 21.In the formation warping part, end 31 of Stamping Steel Ribbon 3, warping part 31 is towards water inlet direction, and the thinner thickness of described warping part 31, easily elastic strain occurs.
Tool joint pin 1 is inserted in female joint 2, and tool joint pin 1 insertion end 11 is formed with tapering, and Stamping Steel Ribbon 3 is close on insertion end 11 outer wall of tapering.When having current to pass through in the duct, pressure extrusion Stamping Steel Ribbon 3 warping part 31 of current, make it that resiliently deformable occur, Stamping Steel Ribbon 3 warping part 31 is close to tool joint pin 1 to be had on insertion end 11 outer wall of tapering, plays sealing process, and, when hydraulic pressure is larger, the elastic strain that Stamping Steel Ribbon 3 warping part 31 occurs is larger, and Stamping Steel Ribbon 3 warping part 31 and tool joint pin 1 have insertion end 11 outer wall of tapering to fit tightr, and encapsulation is better.
As shown in Figure 4, the madial wall that described Stamping Steel Ribbon 3 is arranged on female joint 2 forms assembly department 32, the thickness of Stamping Steel Ribbon 3 is thinning gradually by assembly department 32 to warping part 31, make current when crush seal bar 3, Stamping Steel Ribbon 3 elastic strain is more easy, and then making Stamping Steel Ribbon 3 warping part 31 and tool joint pin 1 have insertion end 11 outer wall of tapering to fit more tight, encapsulation is better.
Described Stamping Steel Ribbon 3 comprises back side 33 and upstream face 34, and in upstream face 33 and formation warping part, back side 34 joint 31, back side 33 is set to arc shaped surface, to strengthen the elasticity of Stamping Steel Ribbon 3, and upstream face 34 can be arc shaped surface, also can be plane, or other shaped face.
The utility model in use, tool joint pin 1 and female joint 2 connecting tube respectively, tool joint pin 1 is inserted in female joint 2, and tool joint pin 1 insertion end 11 is formed with tapering, Stamping Steel Ribbon 3 warping part 31 is close on insertion end 11 outer wall of tapering, and warping part 31 is towards water inlet direction.The utility model is made up of tool joint pin 1 and female joint 2, and structure is simple, and convenience quick for installation, also can install without the need to professional workforce.
The foregoing is only an embodiment of the present utility model, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection domain of this case.
