Description
Technical Field
[0001] The utility model relates to the technical field of building facilities, in particular to a steel structure staircase. Background Art
[0002] Steel structure is a load-bearing structure formed by connecting steel or steel plates through riveting, stamping, welding, etc. It has the characteristics of high strength, good rigidity, and easy disassembly. It is used in the fields of bridges and marine engineering.
[0003] Steel structure stairs are a type of staircase system made of steel as the main material. They have the characteristics of strong bearing capacity, changeable shape, good durability, environmental protection and energy saving. They are often used in shopping malls, office buildings and other buildings. However, they are susceptible to corrosion, so they need to be treated with rust prevention.
[0004] In the prior art, when going up stairs, for some elderly people or people with mobility impairments, climbing stairs is a time-consuming and laborious activity. For this reason, we propose a steel structure staircase. Utility Model Content
[0005] In view of the above problems, the utility model provides a steel structure staircase, which is convenient for the elderly to climb.
[0006] The technical solution of the utility model is: it includes a stair main body, a first slide groove is opened on one side of the stair main body, a second slide groove is opened at one end inside the first slide groove, a first tooth is fixedly connected inside the first slide groove, a belt gear is slidably connected inside the first slide groove, the first tooth is meshed with the outer side of the belt gear, and the outer side of the belt gear is rotatably connected to a connecting block, and the connecting block is fixedly connected to a servo motor on the side away from the stair main body, the output end of the servo motor is rotatably connected to a belt, and the belt is rotatably connected to the belt gear at one end away from the servo motor, a limiting slider is fixedly connected to one side of the bottom of the connecting block, and the limiting slider is slidably connected inside the second slide groove, and a riding component is provided at the end of the bottom of the connecting block away from the limiting slider.
[0007] When going up the stairs, for some elderly people or people with mobility impairments, climbing the stairs is a time-consuming and laborious behavior, and has certain risks. Therefore, by sitting on the riding component and automatically sending the riding component to the top of the stair body, the efficiency of climbing stairs for people with mobility impairments is greatly improved.
[0008] In a further technical solution, a second tooth is fixed inside the second slide groove, a spring shaft is fixed inside the limit slider, a pawl is hinged on the outside of the spring shaft, a baffle is fixed on the inside of the limit slider, a self-locking spring limit column passes through the inside of the baffle, and a pawl is engaged on the outside of the second tooth.
[0009] When the device moves upward, unexpected situations such as power outages may occur, causing the servo motor to stop working, and the device may drop rapidly, causing damage to the members on the device. Therefore, through the cooperation of the pawl and the second tooth, the device will be stuck in its position when encountering an unexpected situation, greatly reducing the possibility of injury to the members of the device due to unexpected situations such as power outages.
[0010] In a further technical solution, the riding component includes a fixed shaft, and the outer side of the fixed shaft is rotatably connected to a seat plate.
[0011] When the device is not needed, the seat is opened, occupying the use space of the stair main body, making it inconvenient for other people to use it. Therefore, the seat is stored by fixing the axis, reducing the space occupied by the device when not in use.
[0012] In a further technical solution, a roller groove is provided on the top of the limiting sliding block, and a roller is rotatably connected inside the roller groove.
[0013] When the second slide groove and the limit slider rub against each other, the friction force may be too large, resulting in a reduction in service life. Therefore, the roller is used to reduce the friction force between the two, thereby increasing the service life of the device.
[0014] In a further technical solution, extrusion blocks are fixedly connected to both ends of the second chute.
[0015] When the device is limited by the pawl, the influence of the pawl on the pawl by manually adjusting the self-locking spring limit column is inefficient, so the pawl is automatically adjusted by the extrusion blocks at both ends of the second slide groove, thereby increasing the efficiency of the device.
[0016] In a further technical solution, a sensing component is fixedly connected to one side of the top of the stair body.
[0017] The servo motor is driven to flip and drive the device downward, thereby increasing the efficiency of the device.
[0018] In a further technical solution, an anti-slip pad is fixed to the top inner side of the stair body.
[0019] The anti-slip pad increases the friction on the surface of the stair main body and reduces accidents caused by the slippery surface of the stair main body.
[0020] The beneficial effects of the utility model are:
[0021] 1. When going up the stairs, for some elderly people or people with mobility impairments, climbing the stairs is a time-consuming and laborious behavior, and has certain risks. Therefore, by sitting on the riding component and automatically sending the riding component to the top of the stair body, the efficiency of climbing stairs for people with mobility impairments is greatly improved.
[0022] 2. When the device moves upward, unexpected situations such as power outages may occur, causing the servo motor to stop working, and the device may drop rapidly, causing damage to the members on the device. Therefore, through the cooperation of the pawl and the second tooth, the device will be stuck in its position when encountering an unexpected situation, greatly reducing the possibility of injury to the members of the device due to unexpected situations such as power outages.

[0031] The embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0032] Example:
[0033] like Figures 1-6As shown, it includes a stair body 1, a first slide groove 11 is provided on one side of the stair body 1, a second slide groove 16 is provided on one end inside the first slide groove 11, a first tooth 19 is fixedly connected inside the first slide groove 11, a shaft gear 12 is slidably connected inside the first slide groove 11, a first tooth 19 is meshed on the outside of the shaft gear 12, a connecting block 15 is rotatably connected on the outside of the shaft gear 12, a servo motor 13 is fixedly connected to the servo motor 13 on the side where the connecting block 15 is away from the stair body 1, a limit slider 17 is fixedly connected to the bottom side of the connecting block 15, a limit slider belt 14 is slidably connected inside the second slide groove 16, and the belt 14 is rotatably connected to the shaft gear 12 on one end away from the servo motor 13, the connecting block 15 is rotatably connected to the bottom side of the limit slider 17. A riding component 18 is provided at the end. When working, first sit on the riding component 18, and then drive the servo motor 13, so that the servo motor 13 drives the belt 14 and the shaft gear 12 to start rotating. Because the shaft gear 12 is engaged with the first tooth 19 inside the first slide groove 11, the shaft gear 12 will start to move along the first slide groove 11 when rotating, driving the connecting block 15 to start rising inside the stair body 1. The cooperation between the limit slider 17 and the second slide groove 16 lowers the connecting block 15 to keep it stable when rising. When climbing up the stairs, for some elderly people or people with mobility problems, climbing stairs is a time-consuming and laborious behavior, and it is also dangerous. Therefore, by sitting on the riding component 18, the riding component 18 is automatically sent to the top of the stair body 1, which greatly improves the efficiency of people with mobility problems in climbing stairs.
[0034] like Figure 4-Figure 6As shown, the second tooth 22 is fixedly connected to the inside of the second slide groove 16, the spring shaft 21 is fixedly connected to the inside of the limit slider 17, and a pawl 23 is hinged on the outside of the spring shaft 21. The inside of the limit slider 17 is fixedly connected to the baffle 2, and a self-locking spring limiting column 24 is passed through the inside of the baffle 2. The outside of the second tooth 22 is meshed with the pawl 23. In the working room, when the limit slider 17 slides upward in the second slide groove 16, the pawl 23 will be affected by the spring shaft 21 when it touches the second tooth 22, and will be offset, so that the pawl 23 passes smoothly. When the limit slider 17 starts to descend, the baffle 2 will block the pawl 23, so that the pawl 23 is stuck. The pawl 23 is pressed against the second tooth 22 so that the servo motor 13 stops working and the device may fall down quickly, causing damage to the members on the device. Therefore, through the cooperation between the pawl 23 and the second tooth 22, the device will be stuck in its position when encountering an accident, which greatly reduces the possibility of injury to the members of the device due to accidents such as power outages.
[0035] like Figure 1 、 Figure 3 As shown, the riding component 18 includes a fixed shaft 3, and the outer side of the fixed shaft 3 is rotatably connected to the seat plate 31. When working, the seat plate 31 is flipped over by the fixed shaft 3, and the bottom of the seat plate 31 will fit with the bottom of the connecting block 15, so that the seat plate 31 can carry loads. When it is not needed, the seat plate 31 is flipped over again to reset it. When the device is not needed, the seat plate 31 is opened, occupying the use space of the stair body 1, making it inconvenient for other people to use it. Therefore, the seat plate 31 is stored by the fixed shaft 3, which reduces the space occupied by the device on the stair body 1 when not in use.
[0036] like Figure 5 As shown, a roller groove 4 is provided on the top of the limit slider 17, and a roller 41 is rotatably connected inside the roller groove 4. When the limit slider 17 slides inside the second slide groove 16 in the working room, the roller 41 inside the roller groove 4 rotates between the second slide groove 16 and the limit slider 17. When friction occurs between the second slide groove 16 and the limit slider 17, the service life may be reduced due to excessive friction. Therefore, the friction between the two is reduced by using the roller 41, thereby increasing the service life of the device.
[0037] like Figure 4-Figure 6As shown, extrusion blocks 5 are fixed at both ends of the second slide groove 16. When the studio moves the limit slider 17 to the top of the second slide groove 16, the extrusion blocks 5 will squeeze the self-locking spring limit column 24, so that the self-locking spring limit column 24 pushes the pawl 23 and then fixes it. When the limit slider 17 falls into the bottom of the second slide groove 16, another set of extrusion blocks 5 squeezes the pawl 23, and the pawl 23 is reset. When the device is limited by the pawl 23, the influence of manual adjustment of the self-locking spring limit column 24 on the pawl 23 is less efficient, so the pawl 23 is automatically adjusted by the extrusion blocks 5 at both ends of the second slide groove 16, thereby increasing the efficiency of the device.
[0038] like Figure 1-Figure 3 As shown, a sensing component 6 is fixed to one side of the top of the stair main body 1. During operation, when the device is at the top of the stair main body 1 and it is necessary to go upstairs, pressing the sensing component 6 can drive the servo motor 13 to flip and drive the device downward, thereby increasing the efficiency of the device.
[0039] like Figures 1-4 As shown, an anti-slip pad 7 is fixed to the top of the inner side of the stair main body 1. During operation, when it is necessary to climb the stair main body 1 on foot, step on the anti-slip pad 7. The material of the stair is a steel structure, so it will become slippery when encountering moisture. Therefore, the anti-slip pad 7 increases the friction force on the surface of the stair main body 1 and reduces accidents caused by the slippery surface of the stair main body 1.
[0040] The working principle of the above technical solution is as follows: first, sit on the riding component 18, and then drive the servo motor 13, so that the servo motor 13 drives the belt 14 and the shaft gear 12 to start rotating. Because the shaft gear 12 is engaged with the first tooth 19 inside the first slide groove 11, the shaft gear 12 will start to move along the first slide groove 11 when rotating, driving the connecting block 15 to start rising inside the stair body 1. The cooperation between the limit slider 17 and the second slide groove 16 lowers the connecting block 15 to keep it stable when rising. When climbing up the stairs, for some elderly people or people with mobility impairments, climbing stairs is a time-consuming and laborious behavior, and it is also dangerous. Therefore, by sitting on the riding component 18, the riding component 18 is automatically sent up The top of the stair main body 1 greatly improves the efficiency of people with mobility impairments in climbing stairs. When the limit slider 17 slides upward inside the second slide groove 16, the pawl 23 is affected by the spring shaft 21 and deflects when it touches the second tooth 22, allowing the pawl 23 to pass smoothly. When the limit slider 17 starts to descend, the baffle 2 will block the pawl 23, so that the pawl 23 is stuck between the second teeth 22. When the second slide groove 16 rises to the top, it is only necessary to press the self-locking spring limit column 24, and the self-locking spring limit column 24 squeezes the pawl 23, so that the pawl 23 is located above the second tooth 22, so that the limit slider 17 can be smoothly slid down. When the device moves upward, unexpected situations such as power outages may occur, causing the servo motor 13 to stop working. The pawl 23 cooperates with the second tooth 22 so that the device can be stuck in its position in case of an accident, which greatly reduces the possibility of injury to the members of the device due to accidents such as power outages. The seat plate 31 is flipped over by the fixed shaft 3, and the bottom of the seat plate 31 is in contact with the bottom of the connecting block 15, so that the seat plate 31 can bear the load. When it is not needed, the seat plate 31 is flipped over again to reset it. When the device is not needed, the seat plate 31 is opened, occupying the use space of the stair main body 1, making it inconvenient for other people to use. Therefore, the seat plate 31 is stored by the fixed shaft 3, which reduces the space occupied by the stair main body 1 when the device is not in use. When the limit slider 17 slides inside the second slide groove 16, the roller 41 inside the roller groove 4 rotates between the second slide groove 16 and the limit slider 17. When the second slide groove 16 and the limit slider 17 rub against each other, the service life may be reduced due to excessive friction. Therefore, the friction between the two is reduced by the roller 41, which increases the service life of the device. When the limit slider 17 moves to the top of the second slide groove 16, the extrusion block 5 will squeeze the self-locking spring limit column 24, so that the self-locking spring limit column 24 pushes the pawl 23 and then fixes it. When the limit slider 17 falls into the bottom of the second slide groove 16, another set of extrusion blocks 5 squeezes the pawl 23, and the pawl 23 is reset. When the device is limited by the pawl 23,Manually adjusting the self-locking spring limit column 24 to affect the pawl 23 is inefficient, so the pawl 23 is automatically adjusted by the extrusion blocks 5 at both ends of the second slide 16, increasing the efficiency of the device. When the device is at the top of the stair body 1 and it is necessary to go upstairs, pressing the sensing component 6 can drive the servo motor 13 to flip and drive the device downward, increasing the efficiency of the device. When it is necessary to climb the stair body 1 on foot, stepping on the anti-slip mat 7, the material of the staircase is steel structure, so it will become slippery when it encounters moisture. Therefore, the anti-slip mat 7 increases the friction on the surface of the stair body 1, reducing accidents caused by the slippery surface of the stair body 1.
[0041] The above embodiments merely represent specific implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
