Description

Technical Field

[0001] This utility model relates to the field of PPR pipe technology, specifically a PPR hot and cold water pipe. Background Technology

[0002] PPR hot and cold water pipes are made of random copolymer polypropylene and are used to transport cold and hot water. They are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields.

[0003] In existing technologies, multiple PPR water pipes are typically connected using connectors to form a water supply line for hot and cold water delivery. However, in actual use, PPR water pipes have relatively low compressive strength and mechanical strength, especially when laid outdoors. Due to prolonged exposure, they are susceptible to external impacts (such as accidental contact by personnel, equipment movement, or impacts from debris) or environmental stresses (such as wind impacts or ground subsidence), leading to bending, deformation, or even breakage. This not only causes hot and cold water leaks, affecting normal water supply, but may also lead to water waste, equipment damage, and even safety hazards. Therefore, there is a need to develop an improved PPR hot and cold water pipe to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a PPR hot and cold water pipe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PPR hot and cold water pipe, comprising a PPR water pipe, wherein a connecting ring is fixedly installed on the outside of the PPR water pipe, a reinforcing mechanism is provided inside the connecting ring, and a limiting mechanism is provided outside the reinforcing mechanism.

[0006] Preferably, the reinforcing mechanism includes a connecting block, which is slidably installed on the outside of the PPR water pipe. Reinforcing rods are fixedly installed at both ends of the connecting block. Screws are movably installed inside the connecting ring. A surrounding groove is opened inside the connecting ring, and an anti-corrosion rubber ring is movably installed inside the surrounding groove. This facilitates the enhancement of the PPR water pipe's pressure resistance, making the PPR water pipe less prone to bending, deformation, and breakage.

[0007] Preferably, a through groove is provided inside the connecting ring at a position corresponding to the connecting block, the connecting block is slidably installed in the through groove, and the reinforcing rod is slidably installed in the through groove, which facilitates the movement and positioning of the connecting block.

[0008] Preferably, the connecting ring has a groove inside, and the screw is slidably installed in the groove, which facilitates the storage of the screw and avoids contact between the screw and the anti-corrosion rubber ring.

[0009] Preferably, the connecting block has a threaded hole at the position corresponding to the screw, and the screw is threaded into the threaded hole to facilitate the limiting operation of the connecting block.

[0010] Preferably, the limiting mechanism includes a positioning groove, which is formed inside the reinforcing rod. An arc-shaped rod is movably installed inside the positioning groove. Connecting plates are fixedly installed at both ends of the arc-shaped rod. Bolts are movably installed inside the connecting plates. Nuts are installed on the external threads of the bolts, which facilitates the limiting operation of the reinforcing rod and enhances the pressure resistance of the PPR water pipe.

[0011] Compared with the prior art, this utility model provides a PPR hot and cold water pipe with the following advantages:

[0012] 1. This PPR hot and cold water pipe, through its reinforced mechanism, allows for easy positioning of the connecting block by sliding it into the through groove inside the connecting ring during use. This facilitates the fit between the reinforcing rod and the surface of the PPR water pipe. With the help of screws, the connecting block is easily positioned. The enclosing groove allows for the placement of an elastic, corrosion-resistant rubber ring, thus protecting the screws and increasing their lifespan. When the required length of the PPR water pipe is needed, the reinforcing rod can be cut at both ends, allowing for reinforcement of PPR water pipes of different lengths. This high flexibility makes the PPR water pipe less prone to bending, deformation, and breakage.

[0013] 2. This PPR hot and cold water pipe, through the setting of the limiting mechanism, facilitates the positioning of the arc-shaped rod during use through the positioning groove, avoiding large displacement of the arc-shaped rod. The setting of connecting plate, bolt and nut facilitates the limiting of the arc-shaped rod, thereby facilitating the limiting of the reinforcing rod, ensuring tight contact between the reinforcing rod and the PPR water pipe, and thus enhancing the pressure resistance of the PPR water pipe.

[0020] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example 1:

[0023] Please see Figure 1-3 This utility model provides a technical solution: a PPR hot and cold water pipe, including a PPR water pipe 1, a connecting ring 2 fixedly installed on the outside of the PPR water pipe 1, a reinforcing mechanism 3 provided inside the connecting ring 2, and a limiting mechanism 4 provided outside the reinforcing mechanism 3.

[0024] Furthermore, the reinforcing mechanism 3 includes connecting blocks 301, which are slidably installed on the outside of the PPR water pipe 1. Four connecting blocks 301 are arranged in a circular array on the outside of the PPR water pipe 1. Reinforcing rods 302 are fixedly installed at both ends of each connecting block 301. The arc-shaped surfaces of the connecting blocks 301 and reinforcing rods 302 fit against the arc-shaped surface of the PPR water pipe 1. Four screws 303 are movably installed inside the connecting ring 2, corresponding to the positions of the four connecting blocks 301. A surrounding groove 304 is formed inside the connecting ring 2, and an anti-corrosion rubber ring 305 is movably installed inside the surrounding groove 304. The anti-corrosion rubber ring 305 has a certain degree of elasticity, facilitating its installation on the casing. Inside the surrounding groove 304, the connecting block 301 is slidably positioned within the through groove inside the connecting ring 2, facilitating the contact between the reinforcing rod 302 and the surface of the PPR water pipe 1. With the cooperation of the screw 303, the connecting block 301 is easily positioned. The surrounding groove 304 also facilitates the placement of the elastic, corrosion-resistant rubber ring 305, thus protecting the screw 303 and increasing its service life. When the length of the PPR water pipe 1 is required, cutting both ends of the PPR water pipe 1 also facilitates the cutting of the reinforcing rod 302, allowing for reinforcement of PPR water pipes 1 of different lengths. This high flexibility makes the PPR water pipe 1 less prone to bending, deformation, and breakage.

[0025] Furthermore, a through groove is provided inside the connecting ring 2 at the position corresponding to the connecting block 301. The connecting block 301 is slidably installed in the through groove, and the reinforcing rod 302 is slidably installed in the through groove, which facilitates the movement and positioning of the connecting block 301.

[0026] Furthermore, the connecting ring 2 has a groove inside, and the screw 303 is slidably installed in the groove, which facilitates the storage of the screw 303 and prevents the screw 303 from contacting the anti-corrosion rubber ring 305.

[0027] Furthermore, the connecting block 301 has a threaded hole at the position corresponding to the screw 303, and the screw 303 is threadedly installed in the threaded hole, which facilitates the limiting operation of the connecting block 301.

[0028] Please see Figure 4Furthermore, in conjunction with Embodiment 1, the limiting mechanism 4 includes a positioning groove 401, which is formed inside the reinforcing rod 302. Several positioning grooves 401 are equidistantly positioned inside the reinforcing rod 302. An arc-shaped rod 402 is movably installed inside the positioning groove 401, contacting the arc-shaped surface of the positioning groove 401. Connecting plates 403 are fixedly installed at both ends of the arc-shaped rod 402. Bolts 404 are movably installed inside the connecting plates 403, and nuts 405 are installed on the external threads of the bolts 404. The positioning groove 401 facilitates the positioning of the arc-shaped rod 402, preventing large displacement of the arc-shaped rod 402. The connecting plates 403, bolts 404, and nuts 405 facilitate the limiting of the arc-shaped rod 402, thereby facilitating the limiting of the reinforcing rod 302 and ensuring close contact between the reinforcing rod 302 and the PPR water pipe 1, thus enhancing the pressure resistance of the PPR water pipe 1.

[0029] In actual operation, when this device is used, the two ends of the PPR water pipe 1 are cut with tools to a suitable length. Similarly, the reinforcing rod 302 is also cut. The reinforcing rod 302 and the connecting block 301 are passed through the connecting ring 2. With the cooperation of the screw 303, the connecting block 301 is limited. After limiting the four connecting blocks 301, the anti-corrosion rubber ring 305 is pulled to deform it and move it into the inside of the surrounding groove 304 to protect the screw 303. According to the length of the PPR water pipe 1, the arc rod 402 is placed in the positioning groove 401 at a suitable position. The bolt 404 is passed through the connecting plate 403. With the cooperation of the nut 405, the arc rod 402 is limited, so that the reinforcing rod 302 is in close contact with the PPR water pipe 1 for subsequent PPR water pipe 1 docking.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
