[0002] With the development of today's society, elevators, escalators and other equipment are constantly used in our daily lives. For high-rise buildings, such equipment provides great help to the elderly. However, for small-span stairs with few steps and low spans, such as those set up in outdoor public places or duplex houses, most of them do not have corresponding elderly-friendly designs, which brings many inconveniences to the elderly in these occasions. Therefore, smart stairs are currently designed to address this problem. The locking mechanism is used to bear the main gravity of the front part of the stairs.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-6 The present invention provides a technical solution: a modified lifting intelligent stair locking mechanism, including a limit plate 2, one side surface of the limit plate 2 is integrally provided with a locking disk 5, which can make the stair locking more sensitive and at the same time make the connection between the structures more stable, so as to avoid loosening or blocking caused by long-term use, thereby affecting the normal operation of the stairs. A locking groove 1 is provided on the surface of the locking disk 5, and a clamping opening 6 is provided on the inner side of the locking groove 1. An adjusting column 10 is movably inserted into the inner side of the clamping opening 6, and a connecting plate 11 is fixedly installed on the outer end of the adjusting column 10. The surface of the connecting plate 11 on one side of the adjusting column 10 is integrally provided with a locking plate 11. A locking arc plate 9 is provided, and a positioning block 4 is fixedly installed on one side surface of the limit plate 2. One end of the inner side of the clamping opening 6 is arc-shaped, and the outer side of the clamping opening 6 is an open structure. When the stair is in use, the adjusting column 10 is driven by power to rotate in real time on the inner side of the clamping opening 6. When the movement angle of the locking arc plate 9 on the inner side of the locking slide groove 1 is 0, the limit plate 2 can be separated without obstacle relative to the connecting plate 11 with a positive displacement in the clockwise direction. When the movement angle of the locking arc plate 9 on the inner side of the locking slide groove 1 is not 0, the limit plate 2 can only undergo relative angular displacement relative to the connecting plate 11 in the plane where the locking disk 5 is located, and relative displacement cannot occur.

[0023] The locking slot 1 is in the shape of a semicircular arc, and closed blocking grooves 3 are provided on both sides of the bottom of the locking slot 1, so that the locking angle of the locking mechanism can be limited to some extent, avoiding the locking angle adjustment range being too large and affecting the overall locking effect of the stairs. A cross plate 13 is fixedly installed on one side surface of the connecting plate 11, and through holes are provided on the surface of the cross plate 13, which can increase the connection stability between the limit plate 2 and the connecting plate 11. The connecting plate 11 is provided with mounting holes 12 near the four corners, and the locking mechanism is made of ABS material, which can increase the overall strength of the mechanism, make the mechanism's bearing capacity larger, and avoid deformation of the mechanism during long-term use. A guide column 7 is integrally formed on one side surface of the limit plate 2, and a guide groove 8 is provided on the inner side of the guide column 7, which can make the strength of the mechanism installation limit greater and avoid breakage and falling off.

[0024] Working principle: During the operation of the stairs, the locking mechanism can first be composed of the limit plate 2, the connecting plate 11 and the locking disk 5. After the mechanism is assembled, when the stairs are in operation, the adjusting column 10 is driven by power to rotate in real time inside the clamping opening 6. When the movement angle of the locking arc plate 9 inside the locking slot 1 is 0, the limit plate 2 can be separated without obstacle with a positive displacement in the clockwise direction relative to the connecting plate 11. When the movement angle of the locking arc plate 9 inside the locking slot 1 is not 0, the limit plate 2 can only have a relative angular displacement relative to the connecting plate 11 within the plane where the locking disk 5 is located, and cannot Relative displacement occurs. At the same time, during long-term use, the coordinated use of the locking plate 5, the locking slot 1, the clamping opening 6 and the adjusting column 10 can make the stair locking more sensitive and make the connection between the structures more stable, thereby avoiding loosening or falling off or jamming during long-term use, thereby affecting the normal operation of the stairs. At the same time, through the coordinated use of the guide column 7, the limit plate 2 and the connecting plate 11, and the overall use of ABS material, the overall strength of the mechanism can be increased, so that the bearing capacity of the mechanism can be greater, thereby avoiding deformation of the mechanism during long-term use.
