Embodiment Construction

[0032] The following is attached Figure 1-4 The application is described in further detail.

[0033] The embodiment of the present application discloses a telescopic steel pipe. refer to figure 1 , the telescopic steel pipe includes a first steel pipe 1 and a second steel pipe 2 . The first steel pipe 1 and the second steel pipe 2 are arranged coaxially, the outer peripheral wall of the first steel pipe 1 is attached to the inner peripheral wall of the second steel pipe 2 , and the first steel pipe 1 and the second steel pipe 2 are connected by sliding.

[0034] refer to figure 1 with figure 2 The outer circumferential wall of the first steel pipe 1 is fixedly connected with a slide plate 3, the slide plate 3 is an arc-shaped plate, and the side surface of the slide plate 3 close to the first steel pipe 1 is attached to the outer circumferential wall of the first steel pipe 1, thereby improving the connection between the slide plate 3 and the first steel pipe 1. The con...

Abstract

The invention relates to a steel pipe, in particular to a telescopic steel pipe. The telescopic steel pipe comprises a first steel pipe and a second steel pipe, wherein the first steel pipe and the second steel pipe are coaxially arranged, the first steel pipe is slidably connected to the second steel pipe, the outer circumferential wall of the first steel pipe is attached to the inner wall of the second steel pipe, and clamping strips used for clamping the first steel pipe are connected to the second steel pipe; and a positioning ring is connected with an abutting assembly, one end surfaces of the clamping strips are abutting surfaces, when the clamping strips are inserted into clamping grooves, the abutting surfaces are abutted against the inner walls of accommodating grooves, and the abutting assembly is used for being abutted against the sides, away from the abutting surfaces, of limiting rods. The telescopic steel pipe has the effect that the steel pipe is conveniently telescoped, so that the space occupied by the steel pipe is reduced.

Description

technical field [0001] The present application relates to steel pipes, in particular to a telescopic steel pipe. Background technique [0002] A steel pipe is a steel material with a hollow section whose length is much greater than its diameter or circumference. According to the cross-sectional shape, it is divided into circular, square, rectangular and special-shaped steel pipes; according to the material, it is divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes. [0003] At present, the Chinese patent with the publication number CN103322335A discloses a large-scale steel pipe, including a cylindrical straight pipe, the straight pipe has a first port and a second port arranged oppositely, and the first port and the second port are used for For liquid communication, the straight cylinder also has an outer peripheral wall and an inner wall between the first port and the second port, and the large steel pi...
