Description

Technical Field

[0001] This utility model mainly relates to the field of household pipes, specifically to a freeze-resistant and durable household pipe. Background Technology

[0002] Household pipes mainly include water supply pipes and drainage pipes, which differ in material and purpose;

[0003] Flexible hoses are commonly used to connect the sink to the drain pipe to drain water.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] However, during use, one end of the hose is connected to the sink and the other end is connected to the drain pipe. If the size of the hose and the drain pipe are not matched, gaps may appear between them, allowing water to flow out or odors from inside the drain pipe to escape through the gaps.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0007] 1. The technical problem to be solved by the utility model:

[0008] This utility model provides a frost-resistant and durable household pipe to solve the technical problems existing in the background art.

[0009] 2. Technical Solution:

[0010] To achieve the above objectives, the technical solution provided by this utility model is: a frost-resistant and durable household pipe, comprising a rigid pipe structure, wherein a flexible pipe structure is provided at the top of the rigid pipe structure;

[0011] A rigid tube structure includes a rigid tube body, with rotating sealing plates rotatably connected to both sides of the inner wall of one end of the rigid tube body, a planar spiral spring provided between the rotating sealing plates and the rigid tube body, and a lifting ring slidably connected to the outer wall of the rigid tube body, with a sealing strip provided at the bottom of the lifting ring.

[0012] When connecting the sink to the drain pipe via household plumbing, insert the rigid pipe into the drain pipe, then insert the flexible hose into the rigid pipe, with one end of the flexible hose connected to the sink. Then push the lifting ring downwards, causing the lifting ring to move the sealing strip between the rigid pipe and the drain pipe for sealing. Rotating the sealing plate can seal the rigid pipe even when there is no water flowing inside, preventing backflow of odors.

[0013] Furthermore, an installation compartment is provided at the top of the rigid tube body, and a sliding strip is slidably connected inside the installation compartment, with a locking strip provided on the inner side of the sliding strip.

[0014] Furthermore, spring telescopic rods are provided at the top and bottom of the sliding bar, one end of the spring telescopic rod is connected to the mounting chamber, and a sliding rod is provided in the middle of the sliding bar, which is slidably connected to the mounting chamber.

[0015] Furthermore, a rotating disk is rotatably connected to the outer wall of the installation chamber, and a pushing block is provided on the inner side of the rotating disk, with a slot provided at one end of the pushing block.

[0016] Furthermore, the hose structure includes a hose body, and the outer wall of the hose body is provided with positioning grooves. The number of positioning grooves is set to multiple, and the multiple positioning grooves are evenly distributed on the outer wall of the hose body.

[0017] Furthermore, the outer wall of the flexible tube body is slidably connected to the inner wall of the rigid tube body, and the positioning groove is engaged with the locking strip.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0020] This utility model features a downward-sliding sealing strip that can enter the gap between the rigid pipe body and the drain pipe. The outer wall of the sealing strip is inclined, allowing it to seal gaps of different sizes. Furthermore, the rotating sealing plate can seal the interior of the rigid pipe body where there is no water flow, preventing odors from backing up from the drain pipe.

[0021] When the hose structure needs to be installed, adjust the distance from which the hose body extends from the inside of the rigid pipe body according to the distance between the rigid pipe body and the sink. Then, push the locking strip on the inside of the sliding strip to engage with the positioning groove to fix the hose body. The sliding strip fits against the installation chamber and the hose body to achieve a seal between the hose body and the rigid pipe body. Attached Figure Description

[0032] Refer to the attached Figure 1-4 A frost-resistant and durable household pipe includes a rigid pipe structure 1, with a flexible pipe structure 2 disposed at the top of the rigid pipe structure 1;

[0033] The rigid tube structure 1 includes a rigid tube body 101. Rotary sealing plates 102 are rotatably connected to both sides of the inner wall of one end of the rigid tube body 101. A planar spiral spring is provided between the rotating sealing plate 102 and the rigid tube body 101. A lifting ring 103 is slidably connected to the outer wall of the rigid tube body 101. A sealing strip 104 is provided at the bottom of the lifting ring 103.

[0034] When it is necessary to connect the sink to the drain pipe through the household pipe, the rigid pipe body 101 is inserted into the drain pipe, and then the flexible hose structure 2 is inserted into the interior of the rigid pipe structure 1, with one end of the flexible hose structure 2 connected to the sink. Then, the lifting ring 103 is pushed down, and the lifting ring 103 drives the sealing strip 104 to enter between the rigid pipe body 101 and the drain pipe to seal. The rotating sealing plate 102 can seal the rigid pipe body 101 when there is no water flowing inside, thus preventing backflow of odors.

[0035] Furthermore, a mounting chamber 105 is provided at the top of the rigid tube body 101. A sliding strip 106 is slidably connected inside the mounting chamber 105. A locking strip 107 is provided on the inner side of the sliding strip 106. Spring telescopic rods 108 are provided at the top and bottom of the sliding strip 106. One end of the spring telescopic rod 108 is connected to the mounting chamber 105. A sliding rod 109 is provided in the middle of the sliding strip 106. The sliding rod 109 is slidably connected to the mounting chamber 105. The outer wall of the mounting chamber 105 can rotate. A rotating disk 110 is connected, and a pushing block 111 is provided on the inner side of the rotating disk 110. One end of the pushing block 111 is provided with a slot 112. When it is necessary to install a household pipe between the sink and the drain pipe, the rigid pipe body 101 is inserted into the drain pipe. Then, the lifting ring 103 is pushed to slide on the outer wall of the rigid pipe body 101. The lifting ring 103 drives the sealing strip 104 into the gap between the rigid pipe body 101 and the drain pipe to seal the gap and fix the position of the rigid pipe body 101.

[0036] Furthermore, the hose structure 2 includes a hose body 201. The outer wall of the hose body 201 has a positioning groove 202. Multiple positioning grooves 202 are evenly distributed on the outer wall of the hose body 201. The outer wall of the hose body 201 is slidably connected to the inner wall of the rigid pipe body 101. The positioning groove 202 engages with the locking strip 107. One end of the hose body 201 is then connected to the sink, and the other end is inserted into the rigid pipe body 101. Rotating the rotating disk 110 causes the pushing block 111 to contact the sliding rod 109 and push the sliding rod 109 inward. The sliding rod 109 causes the sliding strip 106 to slide on the inner wall of the installation chamber 105. The locking strip 107 on the inner side of the sliding strip 106 engages with the positioning groove 202 to fix and seal the position of the positioning groove 202, thereby connecting the household pipe to the sewer and the sink.

[0037] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
