[0002] PP-RCT and PB are both materials used in plastic pipes. PP-RCT, also known as high-temperature resistant β-crystalline polypropylene, is an upgraded material of PP-R. PB, or polybutene pipe, is a polymer complex synthesized from butene-1. It is a high-molecular-weight inert polymer, known as the "gold among plastics." A hot water pipe structure co-extruded from PP-RCT and PB is a type of hot water pipe processed using co-extrusion molding technology.

[0003] The existing hot water pipe structure, which is co-extruded from PP-RCT and PB materials, has the following drawbacks in practical use:

[0004] In the existing technology, the hot water pipe structure made of PP-RCT and PB dual materials co-extruded together usually requires the use of multiple screws to fix the two hot water pipes together when connecting and splicing them. This is cumbersome and inefficient. Utility Model Content

[0026] The following is in conjunction with the appendix Figures 1-6 The present invention will be further described below.

[0027] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a hot water pipeline structure formed by co-extrusion of PP-RCT and PB dual materials.

[0028] The specific technical solution includes a hot water pipe body 1, with a connecting component 2 at one end. The connecting component 2 includes a connecting seat 201, a connecting ring 202, and a rotating block 204. The connecting seat 201 is fixedly mounted on the outer wall of one end of the hot water pipe body 1, and the connecting ring 202 is fixedly mounted on the outer wall of the other end of the hot water pipe body 1 away from the connecting seat 201. A sealing ring 203 is provided on the outer wall of the connecting ring 202. The rotating block 204 is rotatably connected to the inside of the connecting seat 201, and fixing points are provided on both sides of the outer wall of the rotating block 204. The groove 205 and the connecting seat 201 are internally connected to an arc-shaped block 206, and one end of the arc-shaped block 206 is provided with a fixing block 207. The fixing block 207 is inserted into the inside of the fixing groove 205. The inner wall of the connecting seat 201 is provided with a spring 208 connected to the arc-shaped block 206. The outer wall of the arc-shaped block 206 is provided with a push block 209, and the push block 209 is slidably connected to the outer wall of the connecting seat 201. The hot water pipe body 1 can be connected and spliced ​​without the use of multiple screws, making the operation simpler and improving the connection efficiency of the hot water pipe body 1.

[0029] In specific implementations, such as Figure 1 , 4 and Figure 5 As shown, a filter assembly 3 is provided on the hot water pipe body 1. The filter assembly 3 includes a filter box 301, a filter screen 302, and a socket 304. The filter box 301 is fixedly installed on the hot water pipe body 1. The filter assembly 3 is used to filter alkaline deposits and scale in the hot water, which can prevent alkaline deposits and scale from accumulating and clogging the hot water pipe body 1.

[0030] Furthermore, the filter screen 302 is inserted into the inside of the filter box 301, and the socket 304 is fixedly installed on the outer wall of the filter box 301. The bottom outer wall of the filter screen 302 is fixedly installed with a mounting block 303, and the top outer wall of the mounting block 303 is provided with a sealing gasket 312 that fits against the filter box 301. The sealing gasket 312 can ensure the sealing between the filter box 301 and the mounting block 303 and prevent water leakage.

[0031] Furthermore, the mounting block 303 has a sliding block 305 internally connected to it, and an insert block 306 is fixedly installed on the outer wall of the slider 305. The insert block 306 is inserted into the inside of the socket 304, which can fix the mounting block 303 and further fix the filter screen 302.

[0032] Furthermore, a toothed plate 311 is fixedly installed on the outer wall of the slider 305, and a knob 308 is rotatably connected to the outer wall of the bottom of the mounting block 303 via a bearing. A gear 307 located inside the mounting block 303 is provided at the top of the knob 308. The gear 307 meshes with the toothed plate 311, and the knob 308 can drive the gear 307 to rotate.

[0033] Furthermore, a round rod 309 is fixedly installed on the inner wall of the top of the mounting block 303, and a torsion spring 310 connected to the gear 307 is installed on the outer wall of the round rod 309. When the knob 308 and the gear 307 are not under force, the torsional force of the torsion spring 310 can drive the gear 307 to rotate.

[0034] In specific implementations, such as Figure 6 As shown, the hot water pipe body 1 includes a PP-RCT outer layer 4 and a PB inner layer 5. The PB inner layer 5 is attached to the inner wall of the PP-RCT outer layer 4. The hot water pipe body 1 is a double-layer composite structure formed by the PP-RCT outer layer 4 and the PB inner layer 5 through a co-extrusion molding process.

[0035] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0036] In use, pushing the push block 209 moves the arc-shaped block 206 and the fixing block 207, inserting one of the connecting rings 202 of the two hot water pipe bodies 1 to be connected into the connecting seat 201 of the other hot water pipe body 1. Rotating the rotating block 204 causes the rotating block 204 to block the connecting ring 202. Releasing the push block 209 causes the spring force 208 to push the arc-shaped block 206 and the fixing block 207 to move, allowing the fixing block 207 to be inserted into the fixing groove 205, thus fixing the rotating block 204 and the connecting ring 202. This allows the two hot water pipe bodies to be connected without the need for multiple screws. The fixed connection of body 1 makes operation more convenient and improves the connection efficiency of hot water pipe body 1. After water is heated into hot water, the hot water will contain alkaline deposits and scale. The filter screen 302 can filter the alkaline deposits and scale in the hot water, preventing them from clogging the hot water pipe body 1. Turning the knob 308 drives the gear 307 to rotate and mesh with the toothed plate 311, which can cause the toothed plate 311 to move the slider 305 and the plug 306. This allows the plug 306 to be removed from the socket 304, so that the filter screen 302 can be removed from the filter box 301 to clean the filtered alkaline deposits and scale.
