Description

a household ladder

technical field

The utility model belongs to the technical field of ladders, in particular to a household ladder.

Background technique

A ladder, a daily life utensil, is made of two long and thick poles, with a horizontal pole suitable for climbing in the middle, which is used for climbing. At present, most household ladders are composed of support rods and pedals, which require human assistance or rely on fixed objects to use them. If the force is not used properly, they will shake back and forth, or even fall down, which poses a serious safety hazard. In addition, when the ladder is in use, it cannot be moved at will. When the position needs to be adjusted, people need to get off the ladder first, then manually move the ladder and then climb up the ladder to work, which is more troublesome to use.

Utility model content

The purpose of the utility model is to provide a household ladder in view of the deficiencies in the prior art, which can automatically move and realize the adjustment of the height and the low position, with high safety and convenient use.

In order to achieve the above object, the technical scheme of the present utility model is as follows:

A household ladder is characterized in that: it is mainly composed of a track, a moving mechanism, a first ladder and a second ladder arranged symmetrically, a square frame and a remote control; the upper end of the first ladder and the upper end of the second ladder are respectively The square frame is hinged and arranged in a figure-eight shape, a distance sensor and an inclination sensor are respectively installed on the support rod of the first ladder and the support rod of the second ladder; the lower end of the first ladder and the lower end of the second ladder are respectively It is hinged with the moving mechanism, the track is provided with a chute, the first ladder and the second ladder are respectively moved on the track by the moving mechanism; the remote control is suspended on the first ladder or the second ladder or the square on the frame; the moving mechanism is mainly composed of a moving wheel, an axle, a rotating gear, a rotating motor, a controller and a battery; the axle is hinged with the bottom ends of the two support rods of the first ladder or the second ladder, so The rotating gear is fixed in the middle of the axle, the moving wheel is installed at both ends of the axle, and the moving wheel is located outside the two support rods, and the moving wheel moves in the chute; the rotating motor and The controllers are respectively installed on the inner side of the support rod, the rotating shaft of the rotating motor is connected with a transmission gear, and the transmission gear meshes with the rotating gear; the battery is installed between the two support rods; the battery is used for controlling The rotary motor, the distance sensor and the inclination sensor are respectively electrically connected to the controller; the remote controller is connected to the controller through an infrared receiving device.

The moving wheel of the household ladder moves in the chute of the track, and the rail chute is provided to prevent the ladder from slipping, thereby eliminating the trouble of hand-holding and improving the safety in use. There are hooks on the remote control that can be removed. During use, the remote control can be hung on a pedal or a square frame according to the operator's position for convenience. Both ends of the first ladder and the second ladder are hinged with the square frame and the wheel axle respectively, and the position of the ladder can be adjusted at will when in use, which is convenient to use.

When the left and right position of the ladder needs to be adjusted, set the corresponding moving distance on the controller and then press the corresponding button on the remote controller. The controller at the bottom of the first ladder and the controller at the bottom of the second ladder are controlled by the remote controller to make the two rotating motors. Rotate in the same direction at the same time, the rotating motor drives the transmission gear to rotate, so that the moving wheels of the first ladder and the second ladder move to the left or right at the same time. After the movement, the distance sensor senses the moving distance and transmits the moving distance signal to the The controller, let the controller control the rotating motor to stop moving, and the moving wheel also stops moving to the specified distance.

When the height of the ladder needs to be adjusted, also set the height to be adjusted on the remote control, and then press the corresponding button on the remote control to start the controller to control the moving wheel of the first ladder and the moving wheel of the second ladder to move in opposite directions so that The angle and height between the first ladder and the second ladder are changed to adjust the height of the entire ladder, and the change of the position of the first ladder and the second ladder is sensed through the distance sensor and the inclination sensor.

The length of the track in the utility model is the same as the height of the first ladder and the second ladder. When the included angle between the first ladder and the second ladder is about 180°, that is, in the shape of "one", the first ladder and the second ladder are in the shape of "one". After the rails are overlapped, they can be put away, which can reduce the space occupied by the ladder and facilitate storage.

The utility model further illustrates that the inner side of the track is provided with a plurality of fixing rods. The fixed rod can prevent the ladder from being deformed when it is stressed, and improve the safety of the ladder.

The utility model further illustrates that the bottom of the chute is provided with a plurality of equidistant card slots. The card slot is used to fix the position of the moving wheel and act as a brake. When the moving wheel runs to the slot position, the moving wheel is stuck by the slot and cannot continue to move forward. At this time, the moving wheel will not move in the chute when using the ladder, which improves the safety of the ladder and avoids the trouble of hand-holding. .

The utility model further illustrates that a reducer is installed between the rotating motor and the transmission gear; the reducer is electrically connected with the controller. The reducer can adjust the speed of the moving wheel when it is moving, slowing down the speed of the moving wheel before it stops or rotates to make it run more smoothly.

The utility model further illustrates that a protective cover is installed outside the moving mechanism, and the protective cover is fixed with the two support rods of the first ladder or the second ladder. The protective cover is fixed by screws and two support rods. The protective cover can prevent the axle, rotating motor, controller and battery and other equipment from being polluted by dust and improve their service life. The protective cover can be disassembled for easy maintenance.

The utility model further illustrates that the controller is a 51 single-chip microcomputer.

The beneficial effects that the utility model has are as follows:

The operator can make the first ladder and the second ladder move along the track to the left or right at the same time through the operation of the remote control to adjust the position of the ladder, and adjust the height of the ladder by adjusting the distance between the first ladder and the second ladder. During the adjustment process, it can be completed without the operator climbing up and down on the ladder, the movement is convenient and stable, and the safety is high.
