Automatic retractable self-locking ladder for boats

Abstract

The invention discloses an automatically flexible self-locking ladder for a ship. The ladder comprises a connecting device, a traction device and a plurality of benches, wherein the connecting device comprises two horizontally arranged sliding rail plates and a cross bar connected with the two sliding rail plates, the sliding rail plates comprise insert ends and traction ends, the two armrest parts of the upper bench of the plurality of benches are inserted into the two sliding rail plates from the inserting ends and are connected with the two sliding rail plates in a sliding manner; the cross bar is adjacent to the inserting ends, the upper bench of the plurality of benches can be located on the cross bar by revolving around the inserting ends at specific angles, and the armrest parts of the lower bench of the plurality of benches are positioned and locked into two sliding rail plates; the traction device comprises a first traction member and a second traction member, the first traction member can pull the upper bench of the plurality of benches to unfold the ladder from the traction ends, and the second traction member can pull the lower bench of the plurality of benches to fold the ladder from the traction ends. The automatically flexible self-locking ladder has the multiple advantages of being simple in structure, convenient to operate, safe and reliable to use, being likely to implement and the like, and can be fused with a diving board of the ship, so that the ship is more attractive in appearance.

Description

technical field [0001] The invention relates to a telescopic ladder, in particular to an automatically telescopic and self-locking ladder for boats and boats. Background technique [0002] In order to facilitate the crew to dive, swim or work, fixed escalators or telescopic escalators are usually installed on boats. Fixed escalators take up space on the ship and affect the appearance of the boat. Therefore, telescopic escalators are commonly used. When telescopic escalators are used, usually It is necessary to manually pull the lower section of the escalator to open and retract the escalator, especially when the escalator is retracted, it is very inconvenient for people to operate while standing on the boat. Several sections of escalators slide out at once, which has the problem of easily injuring operators. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes an automatic retractable self-locking ladder for boa...
