[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] like Figures 1-10 The illustration shows a sliding locking type CPVC cable protection pipe according to this embodiment. The cable is inserted into the CPVC cable protection pipe for protection. The CPVC cable protection pipe includes a hollow pipe body 1. The pipe body 1 is molded from CPVC. Extending bodies 2 are formed at both ends of the pipe body 1, extending axially. The extending bodies 2 are thin-plate structures with a wall thickness consistent with that of the pipe body 1. The extending bodies 2 extend outward from the ends of the pipe body 1. The extending bodies 2 are semi-circular and coaxially arranged with the pipe body 1. A circumferentially extending arc-shaped protrusion 21 is formed on the outer circumferential surface of the extending bodies 2. According to actual design requirements, several arc-shaped protrusions 21 are arranged at intervals along the axial direction of the extending bodies 2. A locking plate 3 is arranged on the outer side of each extending body 2. The locking plate 3 is made of plastic. The locking plate 3 is an arc-shaped plate coaxially arranged with the extending body 2, and its inner wall contacts and engages with the outer wall of the extending body 2. The locking plate 3 has an arc-shaped groove 31 machined on each arc-shaped protrusion 21. The two ends of the arc-shaped groove 31 are open and slide on the arc-shaped protrusion 21. Through the above structural design, the locking plate 3 can slide along the arc-shaped protrusion 21 through the arc-shaped groove 31 to realize circumferential movement along the outer extension body 2.

[0030] A limiting structure is machined between the locking plate 3 and the arc-shaped protrusion 21 to prevent the locking plate 3 from disengaging from the arc-shaped protrusion 21 when the locking plate 3 slides.

[0031] An arc-shaped limiting groove is machined on the side of the arc-shaped protrusion 21, and a limiting side plate is machined on the locking plate 3; the limiting side plate is inserted into the limiting groove to prevent the locking plate 3 from disengaging from the arc-shaped protrusion 21 in the height direction. When the locking plate 3 slides on the arc-shaped protrusion 21 through the arc-shaped sliding groove 31, the limiting side plate slides along the arc-shaped limiting groove.

[0032] In this embodiment, several tubes 1 are arranged and connected axially to form a long tube structure. The ends of two adjacent tubes 1 are axially aligned and form a cylindrical assembly where the outer extensions 2 at the beginning and end of the tubes 1 combine. When assembled, the interiors of the outer extensions 2 on both sides form a closed space for cables to pass through. In this assembled state, the locking plate 3 slides along the arc-shaped protrusion 21 to have a locked position and an unlocked position. In the locked position, the locking plate 3 spans between the two outer extensions 2, allowing the arc-shaped groove 31 to slide between the arc-shaped protrusions 21 on both extensions, thus locking and limiting the outer extensions 2 on both sides. Also in the locked position, the locking plate 3 seals the gap between the two outer extensions 2, providing a preliminary seal. In the unlocked position, the locking plate 3 returns to its initial position, allowing the arc-shaped groove 31 to disengage from one of the arc-shaped protrusions 21, thereby allowing the two outer extensions 2 to disengage from each other.

[0033] A stop groove 22 is machined on the outer peripheral surface of the outer extension 2. This stop groove 22 is a countersunk structure and extends axially along the outer extension 2. Several stop grooves 22 are arranged at intervals along the circumference of the outer extension 2. A spring sheet structure is formed on the aforementioned locking plate 3. This spring sheet structure is a long-arm structure that extends a certain length along the circumference of the locking plate 3. The spring sheet structure is integrally formed with the locking plate 3, with one end fixedly connected to the locking plate 3 and the other end forming a spring end. This spring sheet structure has a rebound force in the direction approaching or away from the outer extension 2. A locking protrusion 33 is formed on the elastic end of the spring sheet structure. This locking protrusion 33 faces the outer extension 2. When in the aforementioned unlocked position, the locking protrusion 33 engages with the stop groove 22 on the outer extension 2 on the same side, thereby restricting the movement of the locking plate 3 relative to the outer extension 2. In the locked position, the locking protrusion 33 engages with the stop groove 22 on the first or second side of the outer extension 2 to restrict the movement of the locking plate 3 relative to the outer extension 2. A pull structure is formed on the outer surface of the spring structure. By squeezing this pull structure and applying outward force, the elastic end of the spring structure can be moved outward, thereby disengaging the locking protrusion 33 from the stop groove 22.

[0034] In this embodiment, in the aforementioned combined state, the end face of the outer extension 2 at the head end of the tube 1 is aligned with the end face of the tail end of the tube 1, and the end face of the outer extension 2 at the tail end of the tube 1 is aligned with the end face of the head end of the tube 1. An insertion structure 4 is formed on the end face of each outer extension 2. An insertion mating structure 41 is formed on the end faces of both the head and tail ends of the tube 1. In the aforementioned combined state, the insertion structure 4 at one end and the insertion mating structure 41 at the other end are inserted and sealed along the axial direction of the tube 1. This structural design achieves a seal at the mating position. Specifically, of the insertion structure 4 and the insertion mating structure 41, one is an arc-shaped recessed structure, and the other is an arc-shaped boss structure. In this embodiment, an arc-shaped boss structure is formed on the end face of the outer extension 2 at the head end of the tube 1, while an arc-shaped recessed structure is formed on the end face of the tail end of the tube 1. An arc-shaped recessed structure is formed on the end face of the outer extension 2 at the tail end of the tube body 1, while an arc-shaped protrusion 21 structure is formed on the end face of the head end of the tube body 1.

[0035] In practical use, the two ends of the two tubes 1 are axially aligned and combined to form a cylindrical shape, creating a closed space to protect the cable. The locking plates 3 on both sides of the outer extensions 2 are then slid along the arc-shaped protrusions 21 to the locking position, allowing the arc-shaped grooves 31 to slide between the arc-shaped protrusions 21 on both sides of the outer extensions 2, thus limiting and fixing the outer extensions 2 on both sides axially and radially. Pushing the locking plates 3 to their initial unlocking positions allows the outer extensions 2 on both sides to unlock. When the locking plates 3 are in the locked and unlocked positions, the latching protrusions 33 on the spring structure engage with the corresponding stop grooves 22 to restrict the movement of the locking plates 3. Pulling up the spring structure moves the latching protrusions 33 away from the stop grooves 22, allowing the locking plates 3 to move. The above method allows for the locking or unlocking of two adjacent CPVC cable protection pipes by sliding the locking plate 3. This makes the CPVC cable protection pipes easy to install and remove, saving time and effort. The connection is stable and reliable, and it is not easy to loosen or come off. It can prevent the locking plate 3 from moving and coming off in the locking position, improving the stability of the CPVC cable protection pipe combination connection, effectively meeting the actual use needs of CPVC cable protection pipes, and is highly practical.
