Description
Technical Field
[0001] This utility model belongs to the technical field of anti-odor and anti-insect devices for sewer pipes, specifically relating to a snap-on anti-odor and anti-insect device for sewer pipes. Background Technology
[0002] The snap-on drain pipe odor and insect prevention device is a device used to prevent odors and pests from entering the room. The snap-on design makes installation and disassembly convenient and maintenance simple. This device is widely used in the drainage systems of kitchens, bathrooms and other places to improve the cleanliness and comfort of the living environment.
[0003] However, current odor-proof and insect-proof devices for drain pipes have the following problems: current odor-proof and insect-proof devices for drain pipes cannot ensure the airtightness of the connecting pipe and the drain pipe, which may cause water to overflow or produce odors, and insects to crawl out through the connection between the connecting pipe and the drain pipe. Therefore, we propose a snap-on odor-proof and insect-proof device for drain pipes. Utility Model Content
[0004] The purpose of this invention is to provide a snap-on drain pipe anti-odor and anti-insect device, which can solve the problem that current drain pipe anti-odor and anti-insect devices in related technologies cannot ensure the airtightness of the connecting pipe and the drain pipe, which can lead to water overflow or odor, and insects crawling out through the connection between the connecting pipe and the drain pipe.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A snap-on drain pipe odor-proof and insect-proof device includes a connecting pipe. A rubber buckle is fixedly connected to the outer wall of the connecting pipe. A tensioning device is fixedly connected to the bottom of the rubber buckle. The tensioning device includes a fixing ring. The top of the fixing ring is fixedly connected to the bottom of the rubber buckle. A support frame is fixedly connected to the outer wall of the fixing ring. A rotating ring is rotatably connected to the inner wall of the support frame. A winding post is fixedly connected to the top of the inner wall of the support frame. One end of a rope is fixedly connected to the outer wall of the winding post. The end of the rope away from the winding post is fixedly connected to the inner wall of the rotating ring. When the connecting pipe is connected to the drain pipe, the rubber buckle will wrap around the connection between the connecting pipe and the drain pipe. Then, rotating the rotating ring will cause the rope to tighten the rubber buckle.
[0007] The outer wall of the rotating ring is wavy, and the wavy outer wall is rough.
[0008] The support frame consists of two circular rings and a U-shaped connecting block, with a hollowed-out center.
[0009] The inner wall of the support frame is provided with a limiting device, which includes a movable ring. The outer wall of the movable ring is slidably connected to the inner wall of the support frame. Several triangular blocks are provided at the top of the movable ring. A pull column is fixedly connected to the bottom of the movable ring. A triangular block is fixedly connected to the bottom of the rotating ring. Before rotating the rotating ring, the pull column is pulled first, so that the movable ring moves downward and compresses the spring. The movement of the movable ring will drive the triangular blocks to move, so that the triangular blocks are no longer stuck. At this time, the rotating ring can be rotated. After the rotating ring has finished rotating, the pull column is released, and the spring will drive the movable ring and the triangular blocks to reset through its own elastic force.
[0010] A spring is provided between the movable ring and the fixed ring, and the outer wall of the spring passes through and slides on the bottom of the fixed ring.
[0011] The triangular block is used to restrict the movement of the triangular block, and the top of the moving ring is located on the displacement trajectory of the triangular block.
[0012] The technical effects achieved by this utility model are as follows:
[0013] This invention, through the installation of a tensioning device, coordinates the support frame, swivel, winding post, rope, and rubber buckle. The rotation of the swivel causes the rope to tighten the rubber buckle, which better seals the connection and prevents water or gas leakage. This ensures the airtightness of the connecting pipe and the drain pipe, preventing water overflow, odor, and insects from crawling out through the connection. Furthermore, after tightening the rubber buckle, the connection between the connecting pipe and the drain pipe will not loosen due to external force or vibration, ensuring a stable connection and reducing malfunctions or leaks caused by weak connections.
[0014] This utility model, through the setting of a limiting device, enables the cooperation of the moving ring, triangular block, pull column, spring, triangular block, and rotating ring. The spring will drive the moving ring and triangular block to reset through its own elastic force, thereby locking the triangular block in place. This prevents the rotating ring from rotating in the opposite direction due to external vibration, thus avoiding the problem of the rope being unable to tighten the rubber buckle.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0023] like Figure 1-5 As shown, a snap-on drain pipe odor-proof and insect-proof device includes a connecting pipe 1. A rubber buckle 2 is fixedly connected to the outer wall of the connecting pipe 1. A tensioning device 3 is fixedly connected to the bottom of the rubber buckle 2. The tensioning device 3 includes a fixing ring 31. The top of the fixing ring 31 is fixedly connected to the bottom of the rubber buckle 2. A support frame 32 is fixedly connected to the outer wall of the fixing ring 31. A rotating ring 33 is rotatably connected to the inner wall of the support frame 32. A winding post 34 is fixedly connected to the top of the inner wall of the support frame 32. One end of a rope 35 is fixedly connected to the outer wall of the winding post 34. The end of the rope 35 away from the winding post 34 is fixedly connected to the inner wall of the rotating ring 33. The outer wall is wavy with a rough surface. The support frame 32 consists of two rings and a U-shaped connecting block, with a hollow center. According to the above structure, the rotation of the swivel ring 33 will cause the rope 35 to tighten the rubber buckle 2, which can better seal the connection and prevent water or gas leakage. This ensures the airtightness of the connecting pipe 1 and the drain pipe, preventing water from overflowing or producing odors, and preventing insects from crawling out through the connection between the connecting pipe 1 and the drain pipe. After tightening the rubber buckle 2, the connection between the connecting pipe 1 and the drain pipe will not loosen due to external force or vibration, ensuring a stable connection and reducing malfunctions or leaks caused by an insecure connection.
[0024] When using the device, when connecting the connecting pipe 1 to the drain pipe, the rubber buckle 2 will wrap around the connection between the connecting pipe 1 and the drain pipe. Then, rotate the swivel 33. The rotation of the swivel 33 will cause the rope 35 to tighten the rubber buckle 2, which can better seal the connection and prevent water or gas leakage. This ensures the airtightness of the connecting pipe 1 and the drain pipe, preventing water from overflowing or producing odors, and preventing insects from crawling out through the connection between the connecting pipe 1 and the drain pipe. After tightening the rubber buckle 2, the connection between the connecting pipe 1 and the drain pipe will not loosen due to external force or vibration, ensuring a stable connection and reducing failures or leaks caused by an insecure connection.
[0025] like Figure 1-5 As shown, a limiting device 4 is provided on the inner wall of the support frame 32. The limiting device 4 includes a moving ring 41. The outer wall of the moving ring 41 is slidably connected to the inner wall of the support frame 32. Several triangular blocks 42 are provided on the top of the moving ring 41. A pull post 43 is fixedly connected to the bottom of the moving ring 41. A triangular block 45 is fixedly connected to the bottom of the rotating ring 33. A spring 44 is provided between the moving ring 41 and the fixed ring 31. The outer wall of the spring 44 passes through and slides on the bottom of the fixed ring 31. The triangular blocks 42 are used to limit the movement of the triangular block 45. The top of the moving ring 41 is located on the displacement trajectory of the triangular block 45. According to the above structure, the spring 44 will drive the moving ring 41 and the triangular blocks 42 to reset through its own elastic force, so that the triangular blocks 42 lock the triangular block 45, thereby preventing the rotating ring 33 from rotating in the opposite direction due to external vibration, which would make it difficult for the rope 35 to tighten the rubber buckle 2.
[0026] In use, before rotating the rotating ring 33, first pull the pull column 43, so that the moving ring 41 moves downward and compresses the spring 44. The movement of the moving ring 41 will drive the triangular locking block 42 to move, so that the triangular locking block 42 will no longer lock the triangular block 45. At this time, the rotating ring 33 can be rotated. After the rotating ring 33 has finished rotating, release the pull column 43. The spring 44 will drive the moving ring 41 and the triangular locking block 42 to reset through its own elasticity, so that the triangular locking block 42 locks the triangular block 45, thereby preventing the rotating ring 33 from rotating in the opposite direction due to external vibration, which would make it difficult for the rope 35 to tighten the rubber buckle 2.
[0027] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
