Description

Technical Field

[0001] This utility model relates to the technical field of stairwell elevators, and in particular to a rotating structure for a stairwell elevator. Background Technology

[0002] Currently, with the rapid development of cities in my country and the increasing number of high-rise buildings, the application of elevators has become more widespread. However, my country has also entered a stage of deep aging, and some old residential buildings do not have elevators installed, making it difficult for the elderly to go up and down stairs. Curved stairwell elevators are a good solution. Stairwell elevators have broad development space and application value because they are easy to install and have little impact on the surrounding environment. Stairwell elevators operate through mechanical transmission and electrical control, which makes the power supply wiring of the motor a challenge. Some stairwell elevators use chain drive, with the motor installed on the stairs, requiring only simple wiring.

[0003] Most existing stairwell elevators are designed for passenger use, with a seat and backrest installed above the motor for user convenience. However, due to the angle of the elevator, users can only view the escalator from a fixed angle, making it inconvenient for passengers to get on and off the seats. Furthermore, passengers cannot hold onto the escalator, resulting in poor safety. Utility Model Content

[0020] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1-4The diagram shows a rotating structure for a stairwell elevator, including a base 11, which is the main body of the stairwell elevator and is connected to a track on the stairwell.

[0023] The base 11 is connected to a backrest 12 and a seat cushion 13. The seat cushion 12 and the backrest 13 are rotatably connected. The seat cushion 12 can be folded up to a vertical position and abut against the backrest 13, reducing the space occupied by the seat cushion 12 and making it easier for pedestrians to walk.

[0024] A rotating mechanism is installed on the base 11 to control the rotation of the seat cushion 13 and the backrest 12, so as to accommodate the user's sitting posture.

[0025] The rotating structure includes a connecting plate 14 rotatably mounted on the base 11. The connecting plate 14 and the base 11 are connected by a rotating shaft 15. The connecting plate 14 rotates around the rotating shaft 15. The connecting plate 14 is connected to the bottom of the backrest 12. The seat cushion 13 is located above the connecting plate 14. The seat cushion 13 only abuts against the upper surface of the connecting plate 14. The connecting plate 14 supports the seat cushion 13 in operation.

[0026] Furthermore, the rotating shaft 15 is an eccentric shaft, and the base 11 and the connecting plate 14 are respectively provided with positioning holes 16. The positioning holes 16 are located on one side of the center of the base 11 and the connecting plate 14. The rotating shaft 15 and the positioning holes 16 are detachably connected. The rotating shaft 15 and the positioning holes 16 on the base 11 are fixedly connected. The rotating shaft 15 and the positioning holes 16 on the connecting plate 14 are rotatably connected. When the connecting plate 14 rotates around the eccentric rotating shaft 15, it is convenient to control the seat cushion 13 and the connecting plate 14 to rotate and extend above the base 11, making it convenient for the user to sit.

[0027] Meanwhile, the connecting plate 14 and the base 11 can be provided with two pairs of positioning holes 16, which are symmetrically arranged. Only one rotating shaft 15 is connected to the base 11. By controlling the connection between the rotating shaft 15 and the positioning hole 16, the rotation angle of the connecting plate 14 can be affected, which is convenient for adapting to the installation of the corridor elevator in different directions and improving its applicability.

[0028] The connecting plate 14 is equipped with a limiting device, which controls the rotation angle between the connecting plate 14 and the rotating shaft 15 to prevent the connecting plate 14 from driving the seat cushion 13 to rotate to another position and affecting normal movement.

[0029] The limiting device includes a connecting ring 17, which is fixedly connected to the rotating shaft 15. The connecting ring 17 is located between the base 11 and the connecting plate 14. The connecting ring 17 is provided with a termination groove 18 and a starting groove 19. The termination groove 18 and the starting groove 19 are located on the periphery of the connecting ring 17, and the openings of the termination groove 18 and the starting groove 19 face away from the axis of the rotating shaft 15, so as to facilitate insertion.

[0030] In this embodiment, the angle between the termination groove 18 and the starting groove 19 is 90 degrees, which facilitates the guiding of the rotating shaft 15 and the connecting plate 14 to limit the rotation by 90 degrees, and prevents the rotation from reaching an angle that affects the movement of the elevator in the corridor.

[0031] Furthermore, the connecting plate 14 also has a protrusion 20, which is inserted into the termination groove 18 and the starting groove 19. The protrusion 20 abuts against the circumferential surface of the connecting ring 17 and slides along the circumferential surface, making it convenient for the protrusion 20 to be inserted into the termination groove 18 or the starting groove 19.

[0032] The connecting plate 14 has a mounting cavity 21, which is connected to the positioning hole 21. The connecting plate 14 has a movable structure in the mounting cavity 21, which is connected to the protrusion 20. The connecting plate 14 has a through hole 22 in the mounting cavity 21, which is located between the protrusion 20 and the connecting ring 17. The protrusion 20 passes through the through hole 22 and abuts against the connecting ring 17.

[0033] The movable structure includes a locking shaft 23, which is horizontally disposed in the mounting cavity 21. The locking shaft 23 is fixedly connected to the protrusion 20 in the mounting cavity 21, thereby driving the protrusion 20 to move and unlocking the protrusion 20 from the insertion of the termination groove 18 or the starting groove 19.

[0034] Furthermore, the two ends of the locking shaft 23 and the inner wall of the mounting shaft 21 are connected by a spline sleeve. The locking shaft 23 can rotate around its own axis to realize the rotation of the protrusion 20. At the same time, the locking shaft 23 can slide along the axis, thereby driving the protrusion 20 to move horizontally. The protrusion 20 can move away from the through hole 22, which facilitates the rotation of the connecting plate 14.

[0035] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
