Description

Technical Field

[0001] This utility model relates to the technical field of building decoration, and more specifically, to a drain pipe protective cover. Background Technology

[0002] Nowadays, the sewer systems installed in building floors are typically under the floors of bathrooms, kitchens, or public restrooms, primarily for sewage disposal. During installation, the upper-floor users' sewer pipes must be installed above the lower-floor users' sewer pipes. In actual installation, debris from the upper floors often accidentally falls into the sewer pipes, remaining in the bends. After installation, this debris must be manually removed or using appropriate tools to prevent blockages, significantly increasing the difficulty and cost of construction.

[0003] To address the aforementioned issues, patent "CN201874046U" discloses "a construction protective cover for a drain pipe, installed at the opening of a drain pipe, wherein the protective cover is tubular, comprising an outer wall and an inner wall, a groove is provided between the outer wall and the inner wall, and the inner wall is higher than the outer wall." Currently, common household water pipe specifications include: DN15 (4-point pipe), DN20 (6-point pipe), DN25 (1-inch pipe), DN32 (1.2-inch pipe), and DN40 (1.5-inch pipe). The protective caps come in various sizes, including DN50 (2-inch pipe), DN65 (2.5-inch pipe), DN80 (3-inch pipe), DN100 (4-inch pipe), DN125 (5-inch pipe), DN150 (6-inch pipe), DN200 (8-inch pipe), and DN250 (10-inch pipe). However, because the slot positions of the protective caps are fixed, each size cannot well accommodate various sizes of water pipes. Therefore, it is necessary to design protective caps of various sizes, which causes inconvenience in turnover and increases costs, especially for larger protective caps. Utility Model Content

[0004] In view of the above-mentioned technical problems in related technologies, this utility model provides a drain pipe protective cover that can solve the above problems.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0006] A drain pipe protective cover includes a circular upper cover plate. The lower end surface of the upper cover plate is evenly divided into several fan-shaped sections with the center as the center. On two opposite fan-shaped sections, multiple sets of elastic connector mounting parts are symmetrically provided. Each elastic connector mounting part is detachably connected to an elastic connector. The elastic connector includes an L-shaped connecting part and an arc-shaped elastic part connected to the lower end of the connecting part.

[0007] Furthermore, the lower end face of the upper cover plate is provided with a scale line passing through the center of the circle.

[0008] Furthermore, the number of sector partitions is 2N, where N is a positive integer.

[0009] Furthermore, the number of the elastic connector mounting parts is 2M, where M>1 and M is an integer. The elastic connector mounting part includes a longitudinal guide groove formed on the lower end face of the upper cover plate and a transverse mounting groove provided in the upper cover plate. The longitudinal guide groove and the transverse mounting groove are in communication.

[0010] Furthermore, each set of elastic connector mounting parts includes two elastic connector mounting parts symmetrical about the center, and each set of elastic connector mounting parts has a different dimensional spacing, and the side of the elastic connector mounting part is marked with a pipe number.

[0011] Furthermore, the connecting part includes a horizontal connecting piece adapted to the horizontal mounting groove and a vertical connecting piece connected to the elastic part. The horizontal connecting piece has a circular through hole, and the elastic part has an arc-shaped sheet structure.

[0012] The beneficial effects of this utility model are: the structure of the drain pipe protective cover of this application is simple, and the combination of a single upper cover plate and an elastic connector can be applied to drain pipes of different specifications, and it is convenient to reuse.

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] like Figure 1-4 As shown, this utility model discloses a drain pipe protective cover, including a circular upper cover plate 100. The lower end surface of the upper cover plate 100 is evenly divided into several fan-shaped sections with the center as the center. On two opposite fan-shaped sections, multiple sets of elastic connector mounting parts are symmetrically provided. Elastic connectors 200 are detachably connected to the elastic connector mounting parts. The elastic connectors 200 include an L-shaped connecting part 210 and an arc-shaped elastic part 220 connected to the lower end of the connecting part 210. Example 1

[0023] like Figure 2 As shown, the lower end face of the top cover 100 is evenly divided into 8 sector-shaped sections with the center as the center. Two sets of elastic connector mounting parts are symmetrically arranged on two opposite sector-shaped sections, that is, each sector-shaped section has two elastic connector mounting parts. Two elastic connector mounting parts symmetrical with the center as the center form a symmetrical mounting part. Thus, there are a total of 8 sets of symmetrical mounting parts for the 8 sector-shaped sections. Each set of symmetrical mounting parts has a different spacing size. This spacing size is designed according to the different specifications of the drain pipe 300. In practical applications, a medium-sized top cover 100 and a large-sized top cover 100 can be designed. The symmetrical mounting parts corresponding to the small and smaller specifications of the drain pipe are designed on the medium-sized top cover 100, and the symmetrical mounting parts corresponding to the larger and larger specifications of the drain pipe are designed on the large-sized top cover 100.

[0024] In this application, the top cover plate 100 can be made of plastic, and the elastic connector 200 can be made of a metal sheet with good elasticity. Before use, the top cover plate 100 can be stacked, and the elastic connector 200 is small in shape, so it can be placed in different packaging boxes for easy turnover. When in use, the connecting part 210 of the elastic connector 200 is inserted into the longitudinal guide groove 120, and then the transverse connecting piece of the connecting part 210 is inserted into the transverse mounting groove 130 to complete the connection between the top cover plate 100 and the elastic connector 200.

[0025] Furthermore, to better identify which type of drain pipe is suitable for each symmetrical installation section, pipe number markings, such as DN15, DN20, etc., are provided on the side of the flexible connector installation section (the top cover 100 can also be placed on its side to compare each symmetrical installation section with the drain pipe for identification). Even further, the lower end face of the top cover 100 is provided with a scale line 110 passing through the center of a circle. The scale line 110 is offset from the flexible connector installation section and is marked with graduations. For some non-standard drain pipes, after knowing their inner diameter, the flexible connector 200 can be connected to the appropriate scale line by passing a self-tapping screw through the circular through-hole 211. To avoid affecting the horizontal plane of the lower end face of the top cover 100, the scale line, graduations, and pipe number markings can be engraved using a keyboard key lettering method. Ink is scraped across the surface where the lettering is left, and the lettering is printed in the hollowed-out area.

[0026] After selecting a suitable elastic connector and connecting the elastic connector 200, the upper cover plate 100 can be placed on the upper end of the drain pipe 300 through the elastic connector 200. The tension of the elastic part 220 causes the upper cover plate 100 to be snapped onto the pipe opening of the drain pipe 300.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
