Description

Technical Field

[0001] This utility model relates to the field of sewage pipe maintenance technology, and in particular to a sewage pipe inspection port that is easy to install and disassemble. Background Technology

[0002] During the design of sewage pipes, considering internal filtration and blockage, an inspection port is usually required in a suitable area of ​​the main pipe for subsequent dredging and maintenance. However, when dealing with the design of large-diameter metal branch pipes, due to their own diameter and wall thickness, it is not possible to process threads for sealing as with traditional plastic pipes. Instead, bolt fixing is used, which is relatively time-consuming for installation and disassembly. Furthermore, during the fixing process, the position of the cover needs to be constantly adjusted to ensure good sealing, making the operation relatively difficult. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sewage pipe inspection port that is easy to install and disassemble, which addresses the above-mentioned technical deficiencies. The moving ring is displaced by the tightening component, which drives the end cap to close the branch pipe opening. The operation is simple and quick, shortening the operation time. Furthermore, the end cap can be quickly positioned by relying on the connection between the pull rod and the moving ring, and it can achieve a good sealing effect without frequent position adjustments.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model includes: a main pipe and branch pipes, wherein the branch pipes are welded to the main pipe and interconnected with each other, and also includes: an end cap and a moving ring; the branch pipes are symmetrically provided with tightening members, the moving rings are slidably connected to the branch pipes and are in contact with the tightening members; the end caps are provided with pull rods, and the pull rods are connected to the moving rings.

[0005] Preferably, the tightening component includes a lug and an adjusting screw; the lug is fixedly connected to the branch pipe; the adjusting screw is threadedly connected to the lug, and its end contacts the moving ring.

[0006] Preferably, the end of the adjusting screw has a spherical surface.

[0007] Preferably, the branch pipe is provided with at least one slide rail, and the inner circle of the moving ring is provided with a slide groove that cooperates with the slide rail.

[0008] Preferably, the slide rail is provided with a positioning screw at one end near the main pipe.

[0009] Preferably, the movable ring is provided with a snap-fit ​​groove, and one end of the snap-fit ​​groove is enlarged to form a circular channel, and the end of the pull rod is provided with a chuck that passes through the circular channel.

[0010] Preferably, the other end of the snap-fit ​​groove has a limiting groove on the surface of the moving ring near the main pipe.

[0011] Preferably, a sealing gasket is provided at the opening of the branch pipe.

[0012] Preferably, the branch pipe has a fixing groove at the pipe opening for installing a sealing gasket.

[0013] Preferably, a collar is provided on the contact surface between the end cap and the branch pipe.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. After the pull rod is connected and positioned to the moving ring, the two tightening parts are operated to trigger the moving ring to move towards the main pipeline, which can complete the sealing between the end cap and the branch pipeline. The operation is simple and convenient, and there is no need to frequently adjust the position of the end cap, saving operation time.

[0016] 2. The connection between the pull rod, chuck, and snap-fit ​​groove can quickly position the end cap, improving the speed of installation or disassembly. At the same time, the connection between the limiting groove and the chuck can prevent the end cap from turning over, improving the stability after connection.

[0017] 3. The connection between the slide rail and the slide groove enables the guiding and positioning function of the moving ring, and the design of the positioning screw can prevent the two from slipping during use, thus achieving the limit function;

[0018] 4. The installation of the sealing gasket can improve the sealing performance of the pipeline after the end cap is tightened, and the fixing groove of the sealing gasket through machining can improve the stability of the sealing gasket after installation and prevent it from falling off.
