[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The sewage valve flange of this utility model, through the setting of the docking assembly, allows the second flange to pass through the fixed rod and the screw rod and be fitted over the screw rod. During the movement, the second flange presses the rotating block, which can rotate around the shaft into the fixed rod. After the second flange is fitted over the screw rod, under the elastic force of the torsion spring, the rotating block rotates around the shaft out of the fixed rod. By holding the handle with both hands, the gear ring is rotated. The rotation of the gear ring drives the gear to rotate, the gear drives the nut pair to rotate, the nut pair drives the screw rod to move towards the limit ring, the screw rod drives the fixed rod to move, and then drives the rotating block inside the fixed rod to move, so that the rotating block is tightly attached to the outer surface of the flange, thus completing the installation. There is no need to tighten the six bolts in sequence, which greatly reduces the labor intensity during docking and improves the efficiency of docking installation.

Detailed implementation method:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment of this utility model is a sewage valve flange that is easy to connect. The flange 01 and magnet 43 used in this application are products that can be purchased directly on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here.

[0025] Includes: flange 01, flange 01 has a mating assembly 02 inside, and flange 01 has a protective assembly 04 on its outer periphery;

[0026] The docking assembly 02 includes a fixed ring 21, with a gear ring 22 connected to its outer wall. Rotation of the gear ring 22 drives a gear 24 to rotate, which in turn drives a nut assembly 25 to rotate. The nut assembly 25 then drives a lead screw 26 to move towards a limiting ring 27. The lead screw 26 moves a fixed rod 28, which in turn moves a rotating block 30 within the fixed rod 28, causing the rotating block 30 to press tightly against the outer surface of the flange 01. A handle 23 is fixedly connected to both ends of one side of the gear ring 22. Six gears 24 are symmetrically meshed on the outer wall of the gear ring 22. Rotation of the gears 24 drives the nut assembly 25 to rotate, which in turn drives the lead screw 26 to move towards the limiting ring 27. The lead screw 26 moves the fixed rod 28, which in turn moves the rotating block 30 within the fixed rod 28, causing the rotating block 30 to press tightly against the outer surface of the flange 01. A nut assembly 25 is fixedly mounted on the inner wall of the gear 24. When the nut assembly 25 rotates, it drives the lead screw 24 to rotate. 6 moves, thereby moving the limiting ring 27 and the fixed rod 28. The fixed rod 28 moves the rotating block 30 inside it. The nut pair 25 is internally connected to the lead screw 26. One end of the lead screw 26 is fixedly installed with the limiting ring 27, which limits the lead screw 26 and prevents it from rotating. The end of the lead screw 26 away from the limiting ring 27 is fixedly connected to the fixed rod 28. The fixed rod 28 is internally provided with a shaft 29. The middle outer wall of the shaft 29 is connected to the rotating block 30. The rotating block 30 can rotate around the shaft 29 into the fixed rod 28 without affecting the second flange 01 being fitted over the lead screw 26. The rotating block 30 is connected to the fixed rod 28 through a torsion spring 31. The torsion spring 31 provides elastic force. Under the action of the elastic force of the torsion spring 31, the rotating block 30 rotates around the shaft 29 out of the fixed rod 28, so that the rotating block 30 can then be tightly attached to the outer surface of the flange 01.

[0027] Furthermore, the protective component 04 includes a semi-circular cover 41, which protects the flange 01 and the docking assembly 02, preventing sewage from the environment from spilling onto the flange 01 or the docking assembly 02, thus reducing the probability of rust on the parts of the docking assembly 02. A side block 42 is installed on one outer wall of the semi-circular cover 41, and a magnet block 43 is fixedly embedded inside the side block 42. When the two magnet blocks 43 are attracted together, they can limit the semi-circular cover 41. The semi-circular cover 41 can protect the flange 01 and the docking assembly 02, preventing sewage from the environment from spilling onto the flange 01 or the docking assembly 02, thus reducing the probability of rust on the parts of the docking assembly 02.

[0028] Furthermore, the fixing ring 21 is fixedly connected to the flange 01 to ensure the firmness of the fixing ring 21 position. The toothed ring 22 is rotatably connected to the fixing ring 21. The rotation of the toothed ring 22 can drive the gear 24 to rotate. The gear 24 drives the nut pair 25 to rotate. The nut pair 25 drives the lead screw 26 to move towards the limiting ring 27. The lead screw 26 drives the fixing rod 28 to move, which in turn drives the rotating block 30 inside the fixing rod 28 to move, so that the rotating block 30 is tightly attached to the outer surface of the flange 01.

[0029] Furthermore, gear 24 can rotate around the central axis of lead screw 26 on the surface of flange 01. The rotation of gear 24 can drive nut pair 25 to rotate. Nut pair 25 drives lead screw 26 to move towards limit ring 27. Lead screw 26 drives fixed rod 28 to move, which in turn drives rotating block 30 inside fixed rod 28 to move, so that rotating block 30 is tightly attached to the outer surface of flange 01. Lead screw 26 and nut pair 25 are threadedly connected. When nut pair 25 rotates, it can drive lead screw 26 to move, which in turn drives limit ring 27 and fixed rod 28 to move. Fixed rod 28 drives rotating block 30 inside it to move.

[0030] Furthermore, the shaft 29 is fixedly connected to the fixed rod 28 to ensure the stability of the shaft 29 position. The rotating block 30 is rotatably connected to the shaft 29. The rotating block 30 can rotate around the shaft 29 into the fixed rod 28 without affecting the placement of the second flange 01 on the screw 26.

[0031] Furthermore, the two ends of the torsion spring 31 are fixedly connected to the fixed rod 28 and the rotating block 30, respectively. The torsion spring 31 provides elastic force. Under the action of the elastic force of the torsion spring 31, the rotating block 30 rotates around the shaft 29 and out of the fixed rod 28, so that the rotating block 30 can be tightly attached to the outer surface of the flange 01.

[0032] Furthermore, the side block 42 is fixedly connected to the semi-circular cover 41. The semi-circular cover 41 can protect the flange 01 and the docking assembly 02, preventing sewage from the environment from spilling onto the flange 01 or the docking assembly 02, and reducing the probability of rust on the parts of the docking assembly 02. The two magnetic blocks 43 attract each other. After the two magnetic blocks 43 attract each other, they can limit the semi-circular cover 41. The semi-circular cover 41 can protect the flange 01 and the docking assembly 02, preventing sewage from the environment from spilling onto the flange 01 or the docking assembly 02, and reducing the probability of rust on the parts of the docking assembly 02.

[0033] Working principle: In use, first pass the second flange 01 through the fixed rod 28 and the lead screw 26, and place it over the lead screw 26. During movement, the second flange 01 presses against the rotating block 30, which can rotate around the shaft 29 into the fixed rod 28. After the second flange 01 is placed over the lead screw 26, under the elastic force of the torsion spring 31, the rotating block 30 rotates around the shaft 29 out of the fixed rod 28. Hold the handle 23 with both hands and rotate the toothed ring 22. The rotation of gear 24 drives gear 24 to rotate, which in turn drives nut assembly 25 to rotate. Nut assembly 25 drives screw 26 to move towards limit ring 27. Screw 26 drives fixed rod 28 to move, which in turn drives rotating block 30 inside fixed rod 28 to move, so that rotating block 30 is tightly attached to the outer surface of flange 01, completing the installation. Semicircular cover 41 is then placed over flange 01, and two magnet blocks 43 attract each other. Semicircular cover 41 can protect flange 01 and docking assembly 02. The above is the complete working principle of this utility model.
