Abstract

The utility model discloses a prevent flexible ladder connection structure who rocks, including a plurality of pipes that cup joint each other, form on the lateral wall of each pipe and slide the joint recess, slide the inside arch of joint recess and form protruding muscle on the pipe inner wall, correspond, form on the pipe lateral wall and slide the recess, two when the pipe cup joints each other, the protruding muscle of outside pipe is arranged in inside realize the joint in the groove of sliding of pipe, slide the joint recess through setting up, when the pipe that double-phase each other cup joints, through sliding joint recess joint, can effectively prevent to rock, when using, the security is higher.

Description

Prevent flexible ladder connection structure that rocks

Technical Field

The utility model relates to a ladder technical field specifically is a prevent flexible ladder connection structure who rocks.

Background

The side lever of current flexible pipe ladder cup joints the formation each other including a plurality of pipes, because has the gap between the two pipes that cup joint each other, leads to the time-consuming, and the ladder is whole to rock easily, and the user uses and experiences not well.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a prevent flexible ladder connection structure who rocks to there is the gap between two pipes that cup joint each other in solving current ladder among the above-mentioned background art, when leading to the use, the whole easy rock of ladder, and the user uses and experiences not good problem.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a prevent telescopic ladder connection structure who rocks, includes a plurality of pipes that cup joint each other, forms on the lateral wall of each pipe and slides the joint recess, slide the joint recess and inwards protruding formation protruding muscle on the pipe inner wall, correspond, form on the pipe lateral wall and slide the recess, two when the pipe cup joints each other, the protruding muscle of outside pipe is arranged in inside realize the joint in the recess that slides of pipe.

Preferably, the circular tube is provided with two sliding clamping grooves which are arranged on the same axis.

Preferably, the circular tube is provided with three sliding clamping grooves which are distributed at equal angles along the central axis of the circular tube.

Preferably, four sliding clamping grooves are formed in the circular tube and distributed at equal angles along the central axis of the circular tube.

Compared with the prior art, the beneficial effects of the utility model are that: through setting up the joint recess that slides, when two pipes that cup joint each other cup jointed, through sliding joint recess joint, can effectively prevent to rock, when using, the security is higher.
