Description

Technical Field

[0001] The utility model relates to the technical field of stairs, in particular to an intelligent household staircase which can be automatically retracted and extended. Background Art

[0002] Stairs are composed of a flight of continuous steps (also known as stair runs), a platform (resting platform) and enclosure components. Traditional stairs occupy a large area, and some stairs have storage rooms at the bottom, but it is impossible to set up storage rooms for indoor low-rise stairs, thus wasting storage space.

[0003] The existing patent CN215802766U is a smart home staircase that is convenient for storage, including stairs, which include a bottom layer, several middle layers and a top layer, one end of which is provided with a groove, in which a drawer is slidably arranged, and a placement plate is fixedly installed on the other end side of the bottom layer, the middle layer and the top layer, and a slide groove is provided on the upper surface of the bottom layer and the middle layer perpendicular to the direction of the drawer, and pulleys are fixed at the bottom ends of the middle layer and the top layer, and the pulleys are slidably engaged in the corresponding slide grooves, and a connecting component is fixedly provided on the rear end of the upper surface of the top layer. By arranging drawers and placement boards on each layer, the use space of the stairs is increased, and the utilization rate of the indoor space is improved. The stairs are connected to the outer wall through the connecting component for stabilization. When not in use, the top layer, the middle layer and the bottom layer stairs can be overlapped, and the handle can be held to reduce the occupied space through the cooperation of the moving wheels, the pulleys and the slide grooves.

[0004] The following problems exist: each time the stairs are retracted, a person needs to manually push the bottom layer to move so that the bottom, middle and top layers of the stairs can overlap, which is rather troublesome; and the storage space is arranged as a drawer, and the drawer is arranged on the side of the stairs. When the topmost drawer exceeds the taking height of the person, the person needs to stand on the stairs to take the items in the drawer, and there is no protective mechanism, and it is rather dangerous to stand on the stairs to take the items on the side of the stairs, and the person is prone to fall from the stairs; at the same time, when using the drawer, the drawer needs to be pulled as far as possible to maximize the use of the drawer space, and a larger side space is required to facilitate the pulling out of the drawer. When the side space is insufficient, the drawer space cannot be fully utilized.

[0005] Therefore, we propose an automatically retractable smart home staircase to solve the above-mentioned problems. Utility Model Content

[0022] Compared with the prior art, the beneficial effects of the utility model are as follows: a smart home staircase that can be automatically retracted recycles the stairs through a recycling mechanism. When the stairs need to be recycled, the rope is wound around the outside of the spool when the spool rotates, and the rope drives the shaft rod and the pulley to rotate, so that the pulley and the spool are close to each other, and the stairs are automatically recycled. When the stairs are pulled out to the maximum distance, the handle is pressed to engage the locking groove with the locking block, and the roller is limited to avoid injuries to people caused by the movement of the roller when the stairs are used. The opening of the storage tank faces upward.

[0023] 1. Pull the bottom layer outwards by the handle, and the bottom layer drives the middle layer to move outwards through the cooperation of the pulley and the slide groove. When the pulley moves, it drives the shaft rod one to rotate, so that the telescopic winding is wrapped around the outside of the shaft rod one. When the bottom layer moves to the maximum distance, press the handle inwards to make the locking block engage with the locking groove, and limit the roller through the worm gear to avoid the bottom layer from moving and causing harm to personnel when using the stairs. When the handle moves into the groove three, the movable block contacts the fixed block, and then the movable block squeezes the spring one. When the movable block is no longer in contact with the fixed block, the spring one resets and drives the movable block to move between the fixed block and the movable block. The movable block and the handle are limited by the fixed block to avoid the locking groove and the locking block from being disengaged.

[0024] 2. When the stairs need to be reclaimed, press the handle to make the handle continue to move into groove three and squeeze spring three. The movable block contacts the movable resistance block, and the movable block squeezes spring one. When the movable block no longer contacts the movable resistance block, spring one drives the movable block to reset, and then spring three drives the handle to reset, so that the handle moves outward, and the movable block drives the movable resistance block to move and squeeze spring two. When the movable resistance block contacts the fixed resistance block, the movable block squeezes spring one. When the movable block no longer contacts the movable resistance block and the fixed resistance block, the locking groove and the locking block are disengaged, and the torsion spring reset drives the spool to rotate. The spool wraps the rope around the outside and pulls the pulley close to the spool until the top, middle and bottom layers coincide, and the recovery is completed.

[0025] 3. When the storage tank needs to be used, rotate the limit block to release the limit on the left door panel and the right door panel, and rotate the left door panel and the right door panel upward to use the storage tank. The opening of the storage tank faces upward, and there is no risk of falling even if a person stands on the stairs to open the storage tank on the top floor, which increases the safety of use and does not require a large top surface space to maximize the use of the space in the storage tank, which is convenient and easy to use.
