Description

A kind of plastic telescopic section
Technical field
The utility model relates to pipe fitting technical field, is specially a kind of plastic telescopic section.
Background technique
In use, the seal ring of its inside is easily out of shape traditional slip joint, causes sealing effect to reduce.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the plastic telescopic section providing a kind of good sealing effect.
For achieving the above object, the utility model provides following technological scheme: a kind of plastic telescopic section, comprise slip joint body, slip joint body comprises cylindrical shell and sealing drum, described cylindrical shell is connected with the intermediate incline of sealing drum by ring-type, the internal diameter 3cm larger than the internal diameter of cylindrical shell of described sealing drum, the inwall of described cylindrical shell is provided with annular bumping post, described slip joint body is connected with screw lid, the joint of slip joint body and screw lid is provided with the seal ring for sealing, seal ring comprises seal ring body, described seal ring body is provided with the chamfering with intermediate incline adaptation, described seal ring body is also provided with the projection of ring-type.
Further, the outer wall annular array of described screw lid is fluted.
Further, the external diameter of described projection is identical with the internal diameter of sealing drum.
Further, described slip joint body and screw lid are threaded connection.
Contrast the deficiencies in the prior art, the beneficial effect that the technological scheme that the utility model provides is brought: 1. cylinder inboard wall of the present utility model is provided with annular bumping post, makes cylindrical shell be, in adaptive pipeline connection procedure, to play spacing effect, increase work efficiency.2. screw lid outer wall annular array of the present utility model is fluted, tightens or increases frictional force in the process of unclamping, make screw lid be more prone to tighten or unscrew, improve working efficiency for screw lid.3. the chamfering of the intermediate incline on slip joint body of the present utility model and seal ring is adaptive, seal ring is fitted with the inclined-plane of slip joint body in the process used, prevent that the phenomenon of local deformation occurs, and protruding external diameter on seal ring is identical with the external diameter of sealing drum, seal ring is fitted with sealing drum again, and the phenomenon preventing seal ring from producing local deformation further in the process of extruding occurs.
Accompanying drawing explanation
Fig. 1 is package assembly schematic diagram of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the partial schematic sectional view of seal ring.
Embodiment
With reference to Fig. 1-Fig. 3, the utility model is described further.
A kind of plastic telescopic section, comprise slip joint body 1, slip joint body 1 comprises cylindrical shell 11 and sealing drum 12, described cylindrical shell 11 is connected with the intermediate incline 13 of sealing drum 12 by ring-type, the internal diameter 3cm larger than the internal diameter of cylindrical shell 11 of described sealing drum 12, the inwall of described cylindrical shell 11 is provided with annular bumping post 14, described slip joint body 1 is connected with screw lid 2, slip joint body 1 is provided with the seal ring 3 for sealing with the joint of screw lid 2, seal ring 3 comprises seal ring body 31, described seal ring body 31 is provided with the chamfering 32 with intermediate incline 13 adaptation, described seal ring body 31 is also provided with the projection 33 of ring-type.
Cylindrical shell 11 inwall is provided with annular bumping post 14, makes cylindrical shell 11 be, in adaptive pipeline connection procedure, to play spacing effect, increase work efficiency.
Further, the outer wall annular array fluted 21 of described screw lid 2.
Screw lid 2 outer wall annular array fluted 21, tightens for screw lid 2 or increases frictional force in the process of unclamping, making screw lid 2 be more prone to tighten or unscrew, improve working efficiency.
Further, the described external diameter of protruding 33 is identical with the internal diameter of sealing drum 12.
Screw lid 2 outer wall annular array fluted 21, tightens for screw lid 2 or increases frictional force in the process of unclamping, making screw lid 2 be more prone to tighten or unscrew, improve working efficiency.3. the intermediate incline 13 on slip joint body 1 of the present utility model is adaptive with the chamfering 32 of seal ring 3, seal ring 3 is fitted with the inclined-plane of slip joint body 1 in the process used, prevent that the phenomenon of local deformation occurs, and projection 33 external diameter on seal ring 3 is identical with the external diameter of sealing drum 12, seal ring 3 is fitted with sealing drum 12 again, and the phenomenon preventing seal ring 3 from producing local deformation further in the process of extruding occurs.
Further, described slip joint body 1 is threaded connection with screw lid 2.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
