Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 5, the technical solution adopted by the present embodiment is: it comprises a handrail tube 1, a column tube 6, a limit support loose piece 4 and a circular linkage plate 2; the upper end of the upright post pipe 6 is fixedly connected with the loose piece fixing plate 3 through a connecting seat plate 5; the connecting seat plate 5 is fixedly connected with the upright post pipe 6 through a screw 7; the connecting seat plate 5 and the loose piece fixing plate 3 are locked on a coaxial center through a first bolt 9; the center of the circular linkage plate 2 is rotatably connected with the loose piece fixing plate 3 through a first bolt 9; the upper part of the circular linkage plate 2 is welded with the handrail tube 1; the lower end of the circular linkage plate 2 is provided with a first limiting hook 2-2, a second limiting hook 2-4 and a push rod 2-1; the first limiting hook 2-2 is arranged in the middle of the lower end of the circular linkage plate 2, and the second limiting hook 2-4 is arranged on the right side of the lower end of the circular linkage plate 2; the pushing rod 2-1 is arranged on the left side of the lower end of the circular linkage plate 2; an arc-shaped limiting edge 2-3 is arranged between the first limiting hook 2-2 and the second limiting hook 2-4; the limiting supporting loose piece 4 is arranged below the circular linkage plate 2 and is rotationally connected with the loose piece fixing plate 3 through a second bolt 8; the whole limiting and supporting loose piece 4 is of a four-corner star structure; the limiting support loose piece 4 is provided with two arc-shaped limiting grooves 4-1 matched with the limiting hook I2-2, the limiting edge II 2-4 and the arc-shaped limiting edge 2-3; the limiting support loose piece 4 is also provided with two V-shaped limiting grooves 4-2 matched with a second limiting hook 2-4, an arc-shaped limiting edge 2-3 and a push rod 2-1;

when the handrail folding device is used, a set of handrail folding devices with left and right mirror images are needed to be used in a matched mode. When the handrail tube 1 is in an unfolded state, the limiting hook I2-2 and the arc-shaped limiting edge 2-3 on the circular linkage plate 2 are clamped and limited with the V-shaped limiting groove 4-2 on the limiting support loose piece 4, so that the handrail tube 1 is in a supporting position and cannot rotate downwards any more; when the handrail tube 1 needs to be folded, the handrail tube 1 is rotated upwards, the limit of a first limit hook 2-2 on the circular linkage plate 2 is released, a push rod 2-1 on the circular linkage plate 2 pushes against an arc-shaped limit groove 4-1 of a limit support movable block 4, the limit support movable block 4 rotates, the handrail tube 1 is rotated downwards, and when a second limit hook 2-4 on the circular linkage plate 2 pushes against a V-shaped limit groove 4-2 of the limit support movable block 4 and an arc-shaped limit edge 2-3 pushes against an arc-shaped limit groove 4-1 of the limit support movable block, the handrail tube 1 reaches the folding limit; when the handle pipe 1 is to be unfolded from this state, the handle pipe 1 is rotated upward, and this is repeated.
