[0001] The utility model relates to the technical field of pipelines, in particular to a water supply and drainage pipeline connection structure. Background Art

[0002] Announcement number CN221097836U discloses a pipe connection structure for municipal water supply and drainage. A rotatable slider is arranged on the top of the rotating telescopic rod of the device, which can adjust the angle more smoothly.

[0023] By providing the sealing gasket 9 , the sealing performance between the first connecting pipe 16 and the second connecting pipe 12 and the upper supporting seat 10 and the lower supporting seat 8 can be improved.

[0024] By setting the threaded rod 23 , when the threaded rod 23 rotates clockwise, it can control the support frame 20 to rotate upward, and when the threaded rod 23 rotates counterclockwise, it can control the support frame 20 to rotate downward, thereby achieving height adjustment of the support frame 20 .

[0025] Furthermore, a nut 24 is threadedly connected to the surface of the threaded rod 23 , and the lower end surface of the nut 24 rotates with the upper end surface of the base plate 1 .

[0026] By providing the nut 24 , the threaded rod 23 is driven when the nut 24 rotates.

[0027] Furthermore, a telescopic rod 14 is fixedly connected to the upper end surface of the base plate 1 , and a telescopic end of the telescopic rod 14 is fixedly connected to the lower end surface of the support frame 20 .

[0028] The telescopic rod 14 is provided to support the support frame 20 .

[0029] Furthermore, a second threaded hole is formed on the upper end surface of the lower support seat 8 , and a second bolt 11 is threadedly connected between the lower support seat 8 and the upper support seat 10 .

[0030] By providing the second bolt 11 , when the second bolt 11 is inserted into the upper support seat 10 and the lower support seat 8 , a tight connection between the upper support seat 10 and the lower support seat 8 is completed.

[0031] Furthermore, a first limiting groove 7 is opened on the upper end surface of the support plate 2, and a limiting block 6 is slidably connected in the first limiting groove 7. The upper end surface of the limiting block 6 is fixedly connected to a cover plate 5, and the surface of the first bolt is threadedly connected between the cover plate 5 and the support plate 2.

[0032] By providing the cover plate 5, the upper part of the upper support seat 10 is protected to avoid direct impact of rainwater.

[0033] Furthermore, a second limiting groove 13 is formed on the front surface of the second connecting pipe 12 , and the surface of the limiting rod 15 slides into the second limiting groove 13 .

[0034] By providing the limiting rod 15 and the second limiting groove 13 , when the limiting rod 15 is inserted into the second limiting groove 13 , the connection between the first connecting pipe 16 and the second connecting pipe 12 is more stable.

[0035] The working principle of the utility model is as follows: first, the staff pushes the limiting rod 15 straight into the second limiting groove 13, and at the same time moves the first connecting pipe 16 and the second connecting pipe 12 into the sealing gasket 9 of the lower support seat 8, and controls the upper support seat 10 to move downward in the direction of the lower support seat 8 until it pushes into the top of the lower support seat 8, and at the same time rotates the second bolt 11 into the upper support seat 10 and the lower support seat 8 clockwise, so that the installation between the upper support seat 10 and the lower support seat 8 can be completed, and at the same time, the hose 17 is screwed into the first connecting pipe 16 to complete the installation of the drain pipe 19 and the lower support seat 8. During the installation between the first connecting pipe 16, the cover plate 5 is pushed downward onto the top of the support plate 2, and then the first bolt is pushed downward between the support plate 2 and the cover plate 5 to complete the installation, so as to prevent heavy rain and hail from directly impacting the top of the upper support seat 10 to protect it. When the height of the drain pipe 19 needs to be adjusted, the threaded rod 23 is transmitted by the rotation direction of the nut 24 to drive the support frame 20 to move up and down to complete the height adjustment. The pin shaft 21 can limit the drain pipe 19 to prevent the pressure in the drain pipe 19 from being too high and causing a large swing.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
