In the figure: the device comprises a primary pipe assembly 1, a primary pipe 11, a primary slide stopper 12, a primary damping plug 13, a positioning column 14, a clamping protrusion 15, a fixing hole 16, a secondary pipe assembly 2, a secondary pipe 21, a positioning bump 22, a secondary positioning sleeve 23 and a tertiary pipe assembly 3.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 4, the damping telescopic rod comprises a primary tube assembly 1, a secondary tube assembly 2 and a tertiary tube assembly 3, wherein the tail end of the secondary tube assembly 2 is movably nested at the end of the tertiary tube assembly 3, the tail end of the primary tube assembly 1 is movably nested at the end of the secondary tube assembly 2, the primary tube assembly 1 comprises a primary tube 11, a primary sliding stopper 12 and a primary damping stopper 13, the primary damping stopper 13 is fixed at the tail end of the primary tube 11, the secondary tube assembly 2 comprises a secondary tube 21 and a secondary positioning sleeve 24, positioning salient points 22 are integrally arranged on the outer wall of the secondary positioning sleeve 24, and the positioning salient points 22 are clamped in mounting holes at the end of the secondary tube 21.

Integration is provided with reference column 14 and the joint is protruding 15, two on the inner wall of one-level vanes 12 laminate the surface in one-level pipe 11 both sides, reference column 14 and the protruding 15 income of joint are all gone into in the mounting hole on one-level pipe 11, and reference column 14 passes the mounting hole and 16 chucking of fixed orifices on one-level damping stopper 13 are fixed.

The primary damping plug 13 is made of soft rubber and rubber with certain elasticity, one end of the primary damping plug 13 is inserted into the primary tube 11 for a small end, the other end of the primary damping plug 13 is inserted into the diode 21 for a large end, the fixing holes 16 are distributed on two sides of the primary damping plug 13, the primary slip stopping sheet 12 is formed by pressing plastic sheets, when the primary slip stopping sheet 12 is installed on the primary tube 11, the primary damping plug 13 can be clamped by the positioning column 14, an assembly part is single, glue does not need to be applied, the disassembly is convenient, and the working efficiency and the yield are greatly improved. The damping size of the primary damping plug 13 can be selected according to the size and the hardness of the primary material.

The end surfaces of the primary tube 11, the secondary tube 21 and the tertiary tube assembly 3 are circular or regular polygon.

Second grade position sleeve 23 can fix a position one-level stopping piece 12 when one-level pipe assembly 1 draws outward, avoids one-level pipe assembly 1 to deviate from completely at the pull in-process. Similarly, if a multistage pipe fitting is provided, a slip stopper and a damping plug may be installed at the tail end of the secondary pipe 21. And so on.

Because the primary tube 11, the secondary tube 21 and the tertiary tube assembly 3 are installed in a mutually nested mode, the primary tube 11, the secondary tube 21 and the tertiary tube assembly 3 are similar in section and all adopt a round or regular polygon nesting mode, and when a round pipe fitting is adopted, anti-skid convex ribs and grooves are arranged on the side wall of the pipe fitting and are mutually nested, so that the pipe fitting is prevented from rotating, and the stability among the pipe fittings is improved.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
