Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, the terms "a", "an", and "the" mean two or more, unless explicitly defined otherwise.

Example 1

Referring to fig. 1 to 5, the present embodiment provides a technical solution: a high-performance PVC-C cable protection pipe comprises pipe bodies 1, the end parts of the two pipe bodies 1 are connected through a connecting pipe 2, and the connecting pipe 2 comprises pipe sleeves 21 and a corrugated pipe 22, wherein the pipe sleeves 21 are respectively sleeved at the end parts of the two pipe bodies 1, and the corrugated pipe 22 is connected between the two pipe sleeves 21.

In this embodiment, the plurality of clamping jaws 211 are integrally formed at the end of the pipe sleeve 21, the outer side of the plurality of clamping jaws 211 is connected with the screw sleeve 213 in a threaded manner, the outer surface of the clamping jaw 211 is conical and is integrally formed with an external thread, a conical threaded hole 2131 is formed in the screw sleeve 213, the clamping jaw 211 is connected with the threaded hole 2131 in a threaded manner through the external thread, the screw sleeve 213 is sleeved on the outer side of the pipe body 1, the end portion of the pipe body 1 extends into the pipe sleeve 21 from the clamping jaw 211, and then the screw sleeve 213 is screwed so that the screw sleeve 213 can extrude the clamping jaw 211 under the action of the conical threaded hole 2131, so that the clamping jaw 211 clamps the pipe body 1.

Specifically, the anti-slip sleeve 212 made of rubber is disposed at the end of the pipe sleeve 21, and the anti-slip sleeve 212 is sleeved between the pipe body 1 and the clamping jaw 211, so that when the clamping jaw 211 clamps the pipe body 1, the anti-slip sleeve 212 is tightly squeezed between the pipe body 1 and the clamping jaw 211, and the slip phenomenon between the pipe body 1 and the clamping jaw 211 is prevented.

Further, an annular groove 214 is formed on the inner wall of the head end of the pipe sleeve 21, a collar 216 is sleeved in the annular groove 214, a plurality of claws 2161 are integrally formed at the head end of the collar 216, the claws 2161 face the head end of the pipe sleeve 21, the claws 2161 are inclined towards the center of the collar 216, the collar 216 is integrally made of stainless steel material, the tail ends of the claws 2161 are sharp, the tail ends of the claws 2161 protrude out of the inner wall of the pipe sleeve 21, so that when the pipe body 1 extends from the tail end of the pipe sleeve 21 to the head end of the pipe sleeve 21, the direction of the claws 2161 is in the forward direction with the insertion direction of the pipe body 1, at the time, the pipe body 1 can smoothly pass through the collar 216, when the pipe body 1 stops being inserted, the tail ends of the claws 2161 abut against the surface of the pipe body 1, so that when the pipe body 1 is pulled outwards, the pulling direction of the pipe body 1 is opposite to the direction of the claws 2161, the pipe body 1 is abutted against the pipe body 1, thereby preventing the pipe body 1 from moving outwards and fixing the pipe body 1, preventing the pipe body 1 from coming off the pipe sleeve 21.

In addition, the head end and the tail end of the bellows 22 are integrally formed with a convex edge 221, the head end surface of the pipe sleeve 21 is provided with an embedded groove 218, the convex edge 221 extends into the embedded groove 218, so that the convex edge 221 extends into the head end of the pipe sleeve 21, and the purpose of connecting the pipe sleeve 21 and the bellows 22 can be achieved by welding the convex edge 221 and the pipe sleeve 21.

It is worth noting that the inner wall of the pipe sleeve 21 is further provided with a sleeve groove 215, a sealing rubber ring 217 is sleeved in the sleeve groove 215, the sealing rubber ring 217 is sleeved on the outer side of the pipe body 1, so that when the pipe body 1 is sleeved in the pipe sleeve 21, the sealing rubber ring 217 can seal the pipe body 1 and the pipe sleeve 21.

It should be noted that the pipe sleeve 21 and the bellows 22 are made of polypropylene, the wall of the bellows 22 is corrugated, and the polypropylene is also called pleated glue, so that the bellows 22 can be bent, thereby forming various angles between the bent angles of the two pipe bodies 1, and facilitating indoor cable routing work for people.

When the high-performance PVC-C cable protection tube of this embodiment is connected, first, the two pipe sleeves 21 are respectively sleeved on the ends of the two pipe bodies 1, and the ends of the two pipe bodies 1 are respectively inserted into the pipe sleeves 21 from the two ends of the connection pipe 2, so that the pipe bodies 1 pass through the clamping jaws 211, then, as the pipe body 1 is inserted into the pipe sleeve 21, the pipe body 1 will push the convex claws 2161 open, so that the convex claws 2161 always push against the surface of the pipe body 1, preventing the pipe body 1 from being separated from the pipe sleeve 21, finally, the rotating sleeve 213 is rotated to screw the rotating sleeve 213 on the clamping jaw 211, so that the rotating sleeve 213 extrudes the clamping jaw 211 under the action of the tapered threaded hole 2131, thereby leading the clamping jaws 211 to clamp the pipe body 1, achieving the purpose of fixing the pipe sleeve 21 on the pipe body 1, because the bellows 22 can be freely bent, the angle between the two pipe bodies 1 is not limited, so that indoor wiring work can be performed.

Example 2

In order to prevent the sleeve 21 from shaking on the pipe body 1 due to looseness of the rotating sleeve 213 on the clamping jaw 211, as shown in fig. 6 and 7, a counter bore 2132 is formed in the outer surface of the rotating sleeve 213, a resisting bolt 2133 is arranged in the counter bore 2132, the tail end of the resisting bolt 2133 penetrates through the counter bore 2132 and extends into the threaded hole 2131 to be in threaded connection with the rotating sleeve 213, after the rotating sleeve 213 is screwed tightly, the resisting bolt 2133 is screwed tightly, so that the tail end of the resisting bolt 2133 is propped against the clamping jaw 211, and the purpose of preventing the rotating sleeve 213 from loosening is achieved.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
