Abstract
The utility model relates to a plastic inspection chamber base applicable to municipal pipelines drainage system, which comprises a base, a joint pipe for universal joints, a lock lid and a seal ring. The utility model is characterized in that the base is a cylinder with a closed bottom; a universal joint hole with concave spherical inner shape is arranged at the side face of the cylinder; an external screw thread is arranged at the external wall of the universal joint hole near the external lateral part of the base; a spherical universal joint is arranged at the end of the universal joint pipe; a circular groove for the seal ring arrangement is arranged at the external spherical surface of the universal joint; an inner screw thread arranged at the lock lid can match with the external screw thread at the external wall of the universal joint hole. The utility model has the advantages of strong torsion and lift resistance after being connected with pipelines.
Description
Technical field
The utility model relates to a kind of municipal drainage blow-off line testing fixture, particularly a kind of plastic inspection well base.
Background technology
Existing plastic inspection well and pipe joint place adopt modes such as socket joint, welding or bonding adhesive be bonding to be connected, if manhole has little dislocation to bear with adapter, but, cause the leakage of whole tubing or more serious accident to occur in case destroying will appear more greatly in dislocation.
Summary of the invention
The purpose of this utility model is to provide a kind of manhole to be connected the antitorque commentaries on classics in back, the strong structure of anti-lifting with pipeline.
For achieving the above object, the technical solution of the utility model is: a kind of plastic inspection well base is characterized in that being made up of pedestal, gimbal joints pipe, locking closure and sealing ring; Pedestal is the cylindrical shell of bottom lock, the cylindrical shell side is provided with the universal connecting hole that the universal joint with the gimbal joints pipe is connected, the interior shape of universal connecting hole is the concave spherical surface structure, the profile of universal joint is a spherical structure, concave spherical surface structure and spherical structure match, and spherical structure is provided with the annular groove of placing sealing ring; The outer wall of the external side part of universal connecting hole seat is provided with external screw thread, and the permanent universal joint junction block can match with the locking closure that is provided with internal thread.The outstanding advantage of the utility model is: is connected antitorque commentaries on classics afterwards with pipeline, anti-lifting is strong.
Description of drawings
Fig. 1 is a section of structure of the present utility model;
Specific embodiments
As shown in Figure 1, a kind of plastic inspection well base is characterized in that being made up of pedestal 1, gimbal joints pipe 2, locking closure 3 and sealing ring 4; Pedestal 1 is the cylindrical shell of bottom lock, the cylindrical shell side is provided with the universal connecting hole 6 that the universal joint 5 with gimbal joints pipe 2 is connected, the interior shape of universal connecting hole 6 is a concave spherical surface structure 7, the profile of universal joint 5 is a spherical structure 8, concave spherical surface structure 7 matches with spherical structure 8, and spherical structure 8 is provided with the annular groove 9 of placing sealing ring 4; The outer wall of universal connecting hole 6 seat bodies 1 Outboard Sections is provided with external screw thread, and permanent universal joint junction block 2 can match with the locking closure 3 that is provided with internal thread.Because universal connecting hole 6 cooperates the back to form an inner bore with locking closure 3 big; the little structure of outside bore; the spherical structure 8 that just in time cooperates the universal joint 5 of gimbal joints pipe 2 head ends; such combination makes gimbal joints pipe 2 to twist the pipe-line system that better protection is connected with manhole in a bigger scope.
