Although the preferred embodiments of the present utility model are described below, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present utility model more thorough and complete, and to fully convey the scope of the present utility model to those skilled in the art.

[0027] As Figure 1 shown, the present utility model provides a cable protection pipe joint, including:

[0028] A cylinder body 1, with plug-in chambers provided inside both ends of the cylinder body 1 for accommodating the insertion of the cable protection pipe 2;

[0029] Two spring pieces, which are respectively arranged at both ends of the cylinder body 1, and one end of the spring piece extends into the plug-in chamber and is used to clamp the cable protection pipe 2 inserted into the plug-in chamber.

[0030] Specifically, to solve the problem that in the prior art, for a plug-in type cable protection pipe joint, after the cable protection pipe 2 is inserted, it is easy for the cable protection pipe 2 to come out; the cable protection pipe joint provided by the present utility model has a cylinder body 1 and two spring pieces arranged at both ends of the cylinder body 1. The cylinder body 1 provides two plug-in chambers at both ends for the cable protection pipe 2 to insert. One end of the spring piece extends into the plug-in chamber. During the process of inserting the cable protection pipe 2 into the plug-in chamber, one end of the spring piece undergoes elastic deformation, which does not affect the insertion of the cable protection pipe 2. When the cable protection pipe 2 is inserted in place, one end of the spring piece uses its own elastic force to abut against the outer wall of the cable protection pipe 2, realizing the clamping of the cable protection pipe 2 inserted into the plug-in chamber and preventing it from coming out of the plug-in chamber, thereby improving the reliability of the connection of the cable protection pipe 2.

[0031] In this embodiment, the cylinder body 1 is of a cylindrical structure, and the inner diameter of the plug-in chamber is matched with the outer diameter of the cable protection pipe 2.

[0032] Optionally, the inner circumference of the cylinder body 1 is provided with an inwardly protruding convex part 3, and the convex part 3 is located between the two plug-in chambers.

[0033] Specifically, the protrusion 3 separates the two insertion chambers. When the cable protection tube 2 is inserted into the insertion chamber and hits the protrusion 3, it is inserted in place.

[0034] Optionally, the protrusion 3 is an annular structure.

[0035] Specifically, the protrusion 3 is an annular protrusion structure provided on the inner circumference of the cylinder 1, which has the function of limiting the insertion of the cable protection tube 2.

[0036] Optionally, a groove 4 is provided on the inner wall of the insertion chamber. One end of the spring piece is located in the groove 4, and a gap is formed between one end of the spring piece and one side wall of the groove 4. The gap can accommodate the elastic deformation of one end of the spring piece.

[0037] Specifically, the setting of the groove 4 can provide an avoidance space when one end of the spring piece undergoes elastic deformation, avoiding blocking the elastic deformation of the spring piece, and making the insertion operation of the cable protection tube 2 into the insertion chamber easier.

[0038] Optionally, a plurality of deformation portions 5 are provided at one end of the spring piece, and an annular portion 6 connected to the plurality of deformation portions 5 is provided at the other end of the spring piece. The annular portion 6 is connected to the cylinder 1, and the plurality of deformation portions 5 are evenly spaced at one end of the annular portion 6.

[0039] Specifically, the plurality of deformation portions 5 are evenly spaced at one end of the annular portion 6 to form one end of the above-mentioned spring piece. The deformation portions 5 undergo elastic deformation during the insertion of the cable protection tube 2, and use their own elasticity to clamp the cable protection tube 2 after being inserted in place. The plurality of deformation portions 5 are connected to the cylinder 1 through the annular portion 6.

[0040] In this embodiment, as Figure 2 shown, the annular portion 6 and the plurality of deformation portions 5 of the spring piece are integrally formed, and its material is spring steel.

[0042] Optionally, the annular portion 6 is provided with a plurality of through holes 7, and the annular portion 6 is embedded in the side wall of the cylinder 1.

[0043] Specifically, the setting of the plurality of through holes 7 enables the annular portion 6 to be formed in the side wall material of the cylinder 1 in the form of an insert in an integrally formed manner, which is convenient for production and does not require an assembly process.

[0044] Optionally, the deformation portion 5 is strip-shaped, and the plurality of deformation portions 5 form an inwardly converging structure at one end of the annular portion 6.

[0045] Specifically, the deformation portion 5 can be set as a rectangular or strip-shaped structure, one end of which is integrally connected to the annular portion 6, and in order to facilitate the insertion of the cable protection tube 2, multiple deformation portions 5 are arranged inwardly, which can also play a guiding role in the insertion of the cable protection tube 2.

[0046] Optionally, the material of the barrel 1 is plastic.

[0047] Specifically, the cylinder body 1 is made of plastic material such as ABS, PVC or nylon, and is injection molded. During the injection molding process, the spring sheet can be integrally molded inside the material.

After the cable protection tube 2 is inserted into the plug-in chamber, it is clamped by one end of the spring sheet to make it difficult to fall out, thereby improving the stability and reliability of the plug-in.

[0052] Optionally, the cable protection tube 2 is cylindrical.

[0053] Specifically, the shape of the cable protection tube 2 is adapted to the shape of the cylinder body 1 , and when the cable protection tube 2 is inserted into the plug-in chamber in the cylinder body 1 , the gap between the two can be set according to actual needs.

[0054] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
