Description

Technical Field

[0001] The utility model relates to the technical field of plastic plugs, in particular to a plastic plug with a multi-layer sealing structure. Background Art

[0002] Plastic plugs, also known as plastic stoppers or plastic inner plugs, are a commonly used form of pipeline packaging.

[0003] Plastic plugs are usually made of plastic materials such as polyethylene plastic (PE) and are formed in one step through injection molding. They are light, corrosion-resistant, not easy to deform, soft and elastic. They can fit tightly inside or outside the pipe to ensure a sealing effect. They are widely used in sealing various pipes and containers to prevent substances from leaking or entering.

[0004] However, traditional plastic plugs have a simple fixing method, lack effective insect and odor prevention measures, and have poor sealing performance, which can easily cause odor in sewer pipes. In addition, pests such as mosquitoes can easily invade indoors through the gaps between the pipes or the joints between them and the plastic plugs, causing adverse effects on the indoor environment and people's lives. Utility Model Content

[0005] The utility model discloses a plastic plug with a multi-layer sealing structure, which aims to solve the technical problems of simple fixing methods, lack of effective anti-insect and anti-odor measures, poor sealing performance, easy odor generation in sewer pipes, and easy invasion of mosquitoes and other pests into the room through the gaps between the pipes or the connection between the pipes and the plastic plugs, causing adverse effects on the indoor environment and people's lives.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A plastic plug with a multi-layer sealing structure includes a plastic plug body and a fixing sleeve connected to the outer wall of the bottom of the plastic plug body, and further includes:

[0008] Deodorizing mechanism: The deodorizing mechanism is arranged on the circumferential inner wall of the fixing sleeve, a mounting plate is arranged on the circumferential inner wall of the fixing sleeve, an assembly groove is opened on the bottom outer wall of the mounting plate, and a connecting column and a rebound component are arranged on one side inner wall of the assembly groove;

[0009] Mounting mechanism: The mounting mechanism is arranged on the outer wall of the plastic plug body.

[0010] In this case, the combination of the plastic plug body and the fixed sleeve, as well as the anti-odor mechanism inside the fixed sleeve, together constitute a multi-layer sealing structure to enhance the sealing effect. The setting of the rebound component enables the anti-odor mechanism to maintain a certain elasticity and tension during use, and can open and close quickly and automatically, thereby ensuring the sealing effect and preventing odor or mosquito substances from entering through the pipe.

[0011] In a preferred embodiment, the rebound assembly includes a base, which is connected to the inner wall of one side of the assembly groove through a bearing, a fixing column is provided on the top outer wall of the base, and a tension spring is provided on the circumferential outer wall of the fixing column, and the two ends of the tension spring are respectively hung on the top outer wall of the base and the top outer wall of the connecting column, and an assembly column is provided at one end of the fixing column, and one end of the assembly column is connected to the inner wall of one side of the assembly groove through a bearing, and a connecting rod is provided on the circumferential outer wall of the assembly column, and one end of the connecting rod is connected to the insect-proof plate.

[0012] The rebound component provides continuous elastic force through the tension spring to ensure that the plastic plug body and the mating parts always maintain close contact. When the pipe is draining, the water falls onto the insect-proof plate. The tension spring wrapped around the fixed column is subjected to tension to drive the base, fixed column and assembly column to rotate, and the insect-proof plate is forced to flip downward. After drainage is completed, the insect-proof plate is restored to its original position by the rebound force of the tension spring. This design helps prevent gas or mosquitoes from entering the room, thereby improving the overall sealing effect and living comfort.

[0013] In a preferred embodiment, the mounting mechanism includes a mounting sleeve, a thread is provided on the circumferential inner wall of the mounting sleeve, the mounting sleeve is arranged on the outer wall of the plastic plug body, a plurality of equally spaced fixing strips are provided on the bottom outer wall of the mounting sleeve, and a protrusion is provided on the outer wall of one side of the fixing strip.

[0014] Users can easily install or remove the plastic plug by rotating the plastic plug body without using additional tools or equipment. The twisted connection between the plastic plug body and the installation sleeve is used to drive the fixing sleeve to squeeze downward until the bottom end of the fixing sleeve is pushed parallel to the bottom end of the fixing bar. The fixing bar is squeezed, and the protrusions on its outer wall fit tightly against the inner wall of the pipe to achieve installation. This connection method not only enhances the stability of the connection, but also improves the sealing performance, preventing gas or mosquitoes from entering the room.

[0015] As can be seen from the above, a plastic plug with a multi-layer sealing structure includes a plastic plug body and a fixed sleeve connected to the bottom outer wall of the plastic plug body. It also includes: an odor-proof mechanism: the odor-proof mechanism is arranged on the circumferential inner wall of the fixed sleeve, and a mounting plate is provided on the circumferential inner wall of the fixed sleeve. The bottom outer wall of the mounting plate has an assembly groove, and the inner wall of one side of the assembly groove is provided with a connecting column and a rebound component; and an installation mechanism: the installation mechanism is arranged on the outer wall of the plastic plug body. The plastic plug with a multi-layer sealing structure provided by this utility model has the technical effects of preventing insects and odors and improving sealing performance.

[0025] Mounting mechanism: The mounting mechanism is arranged on the outer wall of the plastic plug body 1 .

[0026] A thread groove 3 is formed on the outer wall of the plastic plug body 1 .

[0027] In a specific embodiment, the combination of the plastic plug body 1 and the fixed sleeve 8, as well as the anti-odor mechanism inside the fixed sleeve 8, together constitute a multi-layer sealing structure to enhance the sealing effect. The setting of the rebound component enables the anti-odor mechanism to maintain a certain elasticity and tension during use, and can open and close quickly and automatically, thereby ensuring the sealing effect and preventing odors or mosquitoes from entering through the pipe.

[0028] Reference Figure 1 and Figure 4 In a preferred embodiment, the rebound assembly includes a base 13, which is connected to the inner wall of one side of the assembly groove 10 through a bearing, and a fixing column is provided on the top outer wall of the base 13, and a tension spring 15 is provided on the circumferential outer wall of the fixing column. The two ends of the tension spring 15 are respectively hung on the top outer wall of the base 13 and the top outer wall of the connecting column 14, and an assembly column 11 is provided at one end of the fixing column, and one end of the assembly column 11 is connected to the inner wall of one side of the assembly groove 10 through a bearing, and a connecting rod 12 is provided on the circumferential outer wall of the assembly column 11, and one end of the connecting rod 12 is connected to the insect-proof plate 9.

[0029] The rebound component provides continuous elastic force through the tension spring 15 to ensure that the plastic plug body 1 and the mating parts always maintain close contact. When the pipe is draining, the water falls on the insect-proof plate 9. The tension spring 15 wrapped around the fixed column is subjected to tension to drive the base 13, the fixed column and the assembly column 11 to rotate, and the insect-proof plate 9 is forced to flip downward. After drainage is completed, the insect-proof plate 9 is restored to its original position by the rebound force of the tension spring 15. This design helps to prevent gas or mosquitoes from entering the room, thereby improving the overall sealing effect and living comfort.

The fixing bar 5 is squeezed, and the protrusion 6 on its outer wall fits tightly with the inner wall of the pipe to achieve installation. This connection method not only enhances the stability of the connection, but also improves the sealing performance to prevent gas or mosquitoes from entering the room.

[0032] Reference Figure 2 In a preferred embodiment, the thickness of the fixing strip 5 near the bottom end is greater than the thickness at the top end, and the thread is used in conjunction with the thread groove 3.

[0033] It should be noted that the fixing strip 5 is made of soft plastic near the bottom end. Since the fixing strip 5 is thicker near the bottom end and is made of soft plastic, this part can undergo greater deformation when subjected to pressure, thereby fitting more closely to the mating component and improving the sealing effect.

[0034] Reference Figure 1 In a preferred embodiment, a filter screen 2 is provided on the inner circumferential wall of the plastic plug body 1. The filter screen 2 can effectively block impurities, particles, etc. in the fluid to prevent blockage during drainage.

[0035] Working principle: When in use, insert the installation sleeve 4 into the pipe, rotate the plastic plug body 1, and drive the fixing sleeve 8 to squeeze downward until the bottom end of the fixing sleeve 8 is pushed parallel to the bottom end of the fixing bar 5. The fixing bar 5 is squeezed, and its thickness near the bottom end is larger and is made of soft plastic. The protrusions 6 on the fixing bar 5 near the bottom end and the outer wall are deformed when under pressure and fit tightly against the inner wall of the pipe to achieve installation. When the pipe is draining, water falls onto the insect-proof plate 9, and the tension spring 15 wrapped around the fixed column is subjected to tension to drive the base 13, the fixed column and the assembly column 11 to rotate, and the insect-proof plate 9 is forced to flip downward. After drainage is completed, the insect-proof plate 9 is restored to its original position by the rebound force of the tension spring 15, and automatic opening and closing is completed.
