All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to fig. 1-4, the present invention provides a technical solution: an intelligent adjustable lifting ladder comprises a plate body 1, wherein a through groove 6 is formed in the top of the plate body 1, a frame body 7 is inserted into the through groove 6, support rods 4 are hinged to two sides of the plate body 1, supports 2 are fixed to two sides of the plate body 1, a ladder body 3 is hinged to the supports 2, screw holes 5 which are uniformly distributed are formed in two sides of the ladder body 3, one ends, far away from the plate body 1, of the support rods 4 are connected into the screw holes 5 through screws, support plates 9 are arranged on two sides of the frame body 7, a first sliding groove 10 is formed in the inner side wall of each support plate 9, a first sliding block 11 is connected to each first sliding groove 10 in a sliding mode, pedals 12 are fixed to each first sliding block 11, movable plates 14 are connected to two sides of the inner frame of the frame body 7 in a sliding mode, connecting rods 13 are hinged to one sides of the movable plates 14, one ends, far, the upper portion threaded connection of backup pad 9 has fastening bolt 15, the both sides of framework 7 all are fixed with rack 8, the both sides of plate body 1 all articulate have with rack 8 assorted pawl 17, intelligent alarm device is including setting up in the pressure sensor of ladder body bottom, pressure sensor connection control circuit board, control circuit board is connected with the siren to and battery element.

The alarm is a buzzer.

Specifically, the top of the plate body 1 is fixedly connected to one side of a pawl 17 through a tension spring 18; a tension spring 18 is used to keep the pawl 17 snapped into the gullet of the rack 8. The top of the plate body 1 is hinged with a protective cover 19, and the pawl 17 is positioned in the inner cavity of the protective cover 19; the shield 19 prevents the frame 7 from being lowered by mistakenly touching the click 17. One end of the fastening bolt 15 is fixed to an inner ring of a bearing 16, and an outer ring of the bearing 16 is fixed to the outer side of the movable plate 14; so that the fastening bolt 15 can be smoothly rotated. The upper inner side wall and the lower inner side wall of the frame body 7 are both provided with a second sliding chute 20, a second sliding block 21 is connected in the second sliding chute 20 in a sliding manner, and the second sliding block 21 is fixedly connected with one side of the movable plate 14; so that the movable plate 14 can be guided to move.

According to the working principle or the structural principle, when the ladder is used, after the two ladder bodies 3 are unfolded, the unfolding angles are selected as required, and then the two ladder bodies 3 are respectively inserted into the corresponding screw holes 5 through the screws and then connected into the corresponding support rods 4, so that the two ladder bodies 3 form a ladder frame with a fixed included angle, and a person can climb on the ladder bodies 3; when the height of the ladder frame composed of the ladder bodies 3 cannot meet the requirement, the frame body 7 is pulled upwards to enable the frame body 7 to move upwards, the frame body 7 drives the rack 8 to move upwards when moving upwards, and the pawl 17 is clamped into the tooth groove of the corresponding rack 8 at any time by the pulling force of the tension spring 18, so that the frame body 7 can only move upwards and cannot move downwards; when the position of the pedal 12 needs to be adjusted up and down, the fastening bolt 15 is rotated, so that the fastening bolt 15 drives the movable plate 14 to move, the movable plate 14 drives the first slider 11 to slide in the first sliding groove 10 through the connecting rod 13, and the first sliding groove 10 drives the pedal 12 to move, so that the position of the pedal 12 can be adjusted when the position is not good, and the use is convenient for a user. When the frame body 7 needs to be lowered, the protective cover 19 is opened, and the handle on the side of the pawl 17 is pressed, so that the pawl 17 is separated from the rack 8, and the frame body 7 is lowered under the action of self weight.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
