Abstract

The utility model relates to the field of scaffolds, and discloses a telescopic steel pipe strut for scaffolds, which comprises an outer pipe (1) and an inner pipe (2), wherein the lower end of the inner pipe (2) is positioned inside the outer pipe (1), a plurality of through holes (3) are arranged on the pipe wall of the inner pipe (2) along the length direction, a positioning hole (4) is arranged on the pipe wall of the outer pipe (1), and the positioning hole (4) is correspondingly fixed with different through holes (3) to adjust the length; the anti-deviation block tightly attached to the inner wall of the outer pipe is arranged on the lower end face of the inner pipe, so that the outer pipe and the inner pipe are ensured to be positioned at the same axial lead, and the deformation of the inner pipe caused by long-term inclination is prevented.

Description

Telescopic steel pipe support for scaffold

Technical Field

The utility model relates to a scaffold frame field relates to a prevent inclined to one side flexible steel pipe pillar.

Background

The scaffold refers to various supports erected on a construction site for workers to operate and solve vertical and horizontal transportation. At the present stage, the inner pipe and the outer pipe of the scaffold strut are often connected by adopting a single bolt, and at the moment, the inner pipe is often inclined due to stress, so that the inner pipe and the outer pipe are not on the same axis. Over time, the inner pipe can deform to different degrees, which affects the safety of the scaffold.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem: provides an anti-deflection telescopic steel pipe support, which solves the problem that an inner pipe and an outer pipe are not on the same axial lead.

In order to solve the above problem, the utility model provides a following technical scheme: the utility model provides a scalable steel pipe pillar is used to scaffold frame, includes outer tube, inner tube, the inner tube lower extreme be located inside the outer tube, the inner tube pipe wall be equipped with a plurality of through-holes along length direction, the outer tube pipe wall be equipped with the locating hole, the locating hole correspond different through-holes of fixed with regulation length, the inner tube under the terminal surface be equipped with prevent inclined to one side piece, prevent that the inner tube wall of inclined to one side piece lateral wall and outer tube is hugged closely mutually, form the slip pair.

Furthermore, the anti-deviation block is cylindrical.

Furthermore, the positioning holes are fixed through the bolt fixing through holes.

Furthermore, a fixed disc is fixed on the outer pipe wall of the outer pipe and used for being connected with the cross rod.

Furthermore, eight inserting ports are arranged on the fixed disc, and the inserting ports are fan-shaped.

Further, a base 7 is fixed at the bottom end of the outer tube 1.

Further, the base 7 comprises a frustum-shaped bottom and a sleeve arranged in the center of the frustum-shaped bottom, the bottom end of the outer tube 1 is located inside the sleeve, and the base 7 is connected with the outer tube 1 through a bolt.

The utility model has the advantages that: the anti-deviation block tightly attached to the inner wall of the outer pipe is arranged on the lower end face of the inner pipe, so that the outer pipe and the inner pipe are ensured to be positioned at the same axial lead, and the deformation of the inner pipe caused by long-term inclination is prevented.

Reference numbers in the figures: 1-outer tube, 2-inner tube, 3-through hole, 4-positioning hole, 5-deviation prevention block, 6-fixing disc.

Detailed Description

As shown in fig. 1, the utility model comprises an outer tube 1 and an inner tube 2, wherein the lower end of the inner tube 2 is positioned inside the outer tube 1, the inner tube 2 and the outer tube 1 form a vertical rod with adjustable length, and the inner tube and the outer tube of the vertical rod have only one fixed point. Generally, the pipe wall of the inner pipe 2 is provided with a plurality of through holes 3 along the length direction, the pipe wall of the outer pipe 1 is provided with positioning holes 4, the positioning holes 4 are correspondingly fixed with different through holes 3 to adjust the length, and the positioning holes 4 are connected with the through holes 3 by bolts.

The lower end face of the inner tube 2 is fixed with a deviation prevention block 5, the deviation prevention block 5 is connected with the lower end face of the inner tube 2 through screws, and the side wall of the deviation prevention block 5 is tightly attached to the inner tube wall of the outer tube 1 to form a sliding pair. The anti-deflection block 5 may be cylindrical. When the outer side wall of the inner pipe deviation preventing block 5 is tightly attached to the inner pipe wall of the outer pipe 1, a fixing point is formed between the inner pipe 2 and the outer pipe 1, the two fixing points ensure that the inner pipe 2 and the outer pipe 1 have the same axial lead, and the inner pipe 2 cannot rotate and incline around a bolt due to stress.

The outer tube wall of outer tube 1 is fixed with fixed disc 6, and fixed disc 6 is used for connecting the horizontal pole. Eight inserting ports are arranged on the fixed disk 6, and the inserting ports are fan-shaped.

The bottom end of the outer tube 1 is also provided with a base 7 for stabilizing the vertical rod. The base 7 comprises a frustum-shaped bottom and a sleeve arranged in the center of the frustum-shaped bottom, the bottom end of the outer pipe 1 is located inside the sleeve, and the base 7 and the outer pipe 1 are fixed through bolts.
