It is very convenient to use and enhances the aesthetics.

Description

Aerial work platform guardrail

technical field

The invention relates to an aerial work platform, in particular to a guardrail on the aerial work platform.

Background technique

Aerial work platforms include standing platforms. People stand on the standing platform and rise to a certain height to carry out operations. The door body of the existing standing platform usually does not have a latch device. The railing next to the body is tied, which is very inconvenient and has a low safety factor.

Contents of the invention

The present invention overcomes the shortcomings in the above-mentioned prior art, and provides a guardrail for an aerial work platform that can conveniently lock and open the door.

Technical scheme of the present invention is realized like this:

The guardrail of the aerial work platform is composed of a plurality of railings. There is an opening on one side of the guardrail, and a door is installed at the opening. The right end of the door is hinged with the railing on the right. The body is connected with the railing on the left side of the door body through a latch device.

Preferably, the latch device includes a latch assembly installed on the door body and a baffle installed on the left rail of the door body, the latch assembly includes a hollow crosspiece, and the hollow crosspiece The stopper is arranged on the door body, one end of the hollow crosspiece is closed, and the other end is open, and a stop bar is provided above and below the open end of the hollow crosspiece for resisting the railing, and a bolt, a spring, and a latch are arranged inside the hollow crosspiece. One end of the crosspiece is exposed from the open end of the hollow crosspiece, the other end of the bolt is connected to one end of the spring, the other end of the spring is connected to the closed end of the hollow crosspiece, an opening is provided on the side wall of the hollow crosspiece, and the side wall of the bolt A handle hole is correspondingly provided on the top; in the moving direction of the bolt, the width of the opening on the side wall of the hollow crosspiece is greater than the width of the handle hole of the bolt.

The beneficial effect of the present invention that has adopted above-mentioned technical scheme is:

The latch device of the present invention locks the door body through the cooperation of the latch and the baffle, and the cooperation of the stop bar and the railing; Push the door to open the door; when locked, pull the latch by hand and close the door in the opposite direction. When the bar on the hollow crosspiece touches the railing, the door stops moving and the latch is released. , the latch resets under the force of the spring, and is offset against the baffle on the railing; at this time, the door body is offset by the latch and the baffle in the inward direction, and the baffle bar is offset against the railing in the outward direction, so that the door is fixed. here. It is very convenient to use and enhances the aesthetics.
