Description

Technical Field

[0001] The utility model belongs to the technical field of water inlet structures, and more specifically, particularly relates to a water inlet structure on a sewage lifting device. Background Art

[0002] There is a "water inlet structure" on the water collecting tank of the sewage lifting device, which is responsible for connecting with the drain pipe of the sanitary ware to ensure that the sewage generated by the sanitary ware can flow smoothly and without leakage into the water collecting tank of the sewage lifting device. The water collecting tank is made of plastic and is formed by rotational molding. The "water inlet structure" is in a sealed state when the sewage lifting device leaves the factory. Only during installation will it be cut open by tools according to actual conditions and connected to the drain pipe of the sanitary ware. The water inlet structure on the existing sewage lifting device is divided into a convex structure and a concave structure. The convex structure will bulge outward by at least 5 cm on the surface of the water collecting tank, which will make the outer dimensions of the water collecting tank larger. Due to the thickness of the water collecting tank of the sewage lifting device, the inner diameter of the convex structure is small, resulting in the debris in the sewage generated by the sanitary ware being blocked due to the smaller inner diameter. The concave structure is not convenient to connect when there is an angle deviation between the drain pipe of the sanitary ware and the structure. When the machine vibrates during operation or the pipeline vibrates, the drain pipe and the structure are easily displaced, which eventually leads to detachment from each other and sewage leakage. Therefore, a water inlet structure on a sewage lifting device is proposed. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a water inlet structure on a sewage lifting device. Since the bellows has the effects of stretching, compression and bending, when the bellows is inserted into the sewage pipe of the sanitary ware, it can be connected more conveniently and easily, so as to solve the problem that the convex structure proposed in the above background technology will make the outer dimensions of the water collecting box larger, the inner diameter of the convex structure is relatively small, resulting in blockage of debris in the sewage generated by the sanitary ware due to the smaller inner diameter, and the concave structure is not convenient for connection. When the machine vibrates during operation or the pipeline vibrates, the drain pipe and the structure are easily displaced, which eventually leads to the problem of falling off from each other and sewage leakage.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a water inlet structure on a sewage lifting device, including a water collecting box, a water inlet structure is provided on the outside of the water collecting box, the water inlet structure includes a positioning point, a countersunk hole, a circular groove, a dividing line and a plane, a connecting component is provided on one side of the water inlet structure, the connecting component includes a flange with a flange, a bellows, a convex rib for enhancing the sealing effect, a connecting port and a through hole of a sanitary ware sewage pipe, a matching flange is fixed to one end of the bellows away from the flange, and the other threaded connection of the matching flange is provided with a plurality of matching fasteners.

[0005] As a preferred technical solution of the utility model, the plane is annular in structure, the countersunk hole is located outside the plane, and the circular groove, the dividing line and the plane are arranged in a concentric circle structure.

[0006] As a preferred technical solution of the present utility model, the position of the positioning point coincides with the center of the circular groove.

[0010] As a preferred technical solution of the utility model, the position of the flange of the flanging corresponds to the position of the plane, and the position of the convex rib for enhancing the sealing effect corresponds to the position of the circular groove.

[0011] The utility model provides a water inlet structure on a sewage lifting device, which has the following beneficial effects:

[0012] 1. The water inlet structure on the sewage lifting device, the sewage and debris generated from the sanitary ware, flows into the water inlet structure of the water collecting tank of the sewage lifting device, and will no longer be blocked due to the reduction of the inner diameter of the outer convex structure. The opening diameter of the water inlet structure on the water collecting tank is 115mm, minus the thickness of the bellows, which can ensure that the inner diameter of the water inlet structure is ≥110mm. The debris in the sewage flows into the water inlet structure from the drain pipe of the sanitary ware, and the diameter of the entire flow channel will not decrease.

[0013] 2. The water inlet structure on the sewage lifting device makes it more convenient and easier to connect the drain pipe of the sanitary ware with the water inlet structure of the sewage lifting device, thereby enhancing the sealing effect, enhancing the firmness of the drain pipe of the sanitary ware and the water inlet structure, and solving the problem of the inconvenience of connection when there is an angle deviation between the drain pipe of the sanitary ware and the structure of the concave structure. When the machine vibrates during operation or the pipeline vibrates, the drain pipe and the structure are easily displaced, which eventually leads to the detachment from each other and sewage leakage.

[0023] A φ115mm hole opener is used to open a hole with the positioning point 21 as the center. The diameter of the hole is the same as the diameter of the dividing line 24. The remaining material from the hole is taken out and thrown away. After that, the position of the through hole 35 on the flanged flange 31 is made corresponding to the position of the countersunk hole 22 on the plane 25. The screw is passed through the through hole 35 and is threadedly connected to the countersunk hole 22, thereby connecting the water-entering structure 2 and the connecting component 3. In this process, the convex rib 33 and the circular groove 23 for enhancing the sealing effect are mutually embedded and tightly fit with the circular groove 23 under the action of the tightening force of the screw, which plays the role of the first seal. At the same time, the flanged flange 31 and the plane 25 are tightly fitted under the action of the tightening force, which plays the role of the second seal.

The diameter of the hole is the same as the diameter of the dividing line 24. The remaining material from the hole is taken out and thrown away. After that, the position of the through hole 35 on the flange 31 is made to correspond to the position of the countersunk hole 22 on the plane 25. A screw is passed through the through hole 35 and is threadedly connected to the countersunk hole 22, thereby connecting the water-entering structure 2 and the connecting component 3. In this process, the convex rib 33 and the circular groove for strengthening the sealing effect are 23 are embedded in each other and fit tightly with the circular groove 23 under the action of the tightening force of the screw, which plays the role of the first seal. At the same time, the flanged flange 31 and the plane 25 are tightly fitted under the action of the tightening force, which plays the role of the second seal. After that, the sewage pipe inserted into the sanitary ware is connected to the flange 4 through the matching fastener 5, and the connection is completed by locking the hoop. Since the bellows 32 has the functions of stretching, compression and bending, when the bellows 32 is inserted into the sewage pipe of the sanitary ware, it can be more convenient and easy to connect.
