Description

Technical Field

[0001] This utility model relates to the field of elevator equipment processing technology, and in particular to an elevator door drive structure. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving along at least two rigid tracks perpendicular to the horizontal plane. Existing elevator door drive structures are limited in several ways: firstly, they are inconvenient for moving two elevator doors towards or relative to each other; secondly, the sliding effect of the elevator doors is also poor. Utility Model Content

[0003] The purpose of this utility model is to provide an elevator door drive structure to solve the problems mentioned in the background art and facilitate its promotion.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0005] An elevator door drive structure includes a sill, a drive motor fixedly connected to one side of the inner wall of the sill, a rotating shaft fixedly connected to the output end of the drive motor, and one end of the rotating shaft away from the output end of the drive motor rotatably connected to the other end of the inner wall of the sill. A drive wheel is fixedly sleeved on the outer surface of the rotating shaft, and a drive belt is drivenly connected to the surface of the drive wheel. A double-ended screw is rotatably connected between the two inner walls of the sill located on one side of the rotating shaft, and a driven wheel is fixedly sleeved on the surface of the double-ended screw. The side of the drive belt away from the drive wheel is drivenly connected to the surface of the driven wheel. On the surface, threaded blocks are symmetrically threaded onto the bidirectional screw, and a movable rod is fixedly connected to the bottom of the threaded blocks. A strip-shaped through hole is opened at the bottom of the top sill, and the movable rod passes through the strip-shaped through hole and is slidably connected to it. An elevator door is fixedly connected to the end of the movable rod away from the threaded blocks. A connecting rod is symmetrically connected to the bottom of the elevator door, and a movable seat is fixedly connected to the bottom of the connecting rod. Side balls are symmetrically rolled on the outer wall of the movable seat, and rollers are rotatably connected between the inner walls of the movable seat. A bottom sill is provided at the bottom of the rollers, and evenly distributed balls are rolled on the bottom of the bottom sill.

[0006] Furthermore, the drive wheel is larger than the driven wheel.

[0007] Furthermore, the inner wall of the bottom sill is symmetrically provided with side grooves on both sides, and the side beads are rolled inside the side grooves.

[0008] Furthermore, an inner groove is provided in the middle of the roller, and the top of the ball is located inside the inner groove.

[0009] Furthermore, the bottom of the sill is fixedly connected with evenly distributed mounting blocks, and bolts are threaded onto the mounting blocks.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model discloses an elevator door drive structure. Starting the drive motor causes the rotating shaft to rotate, which in turn drives the drive wheel to rotate. This, in turn, drives the driven wheel via a transmission belt, which in turn drives the bidirectional screw to rotate. This, in turn, moves the threaded blocks on both sides, which in turn moves the elevator door via a moving rod. Simultaneously, the bottom of the roller moves on top of the ball bearing, reducing friction during roller movement and facilitating elevator door sliding. The side ball bearing moves within the side groove, limiting and guiding the roller, enabling convenient relative or opposing movement of the two elevator doors, and facilitating rapid sliding of the two elevator doors.

[0021] Depend on Figures 1 to 5 As shown, an elevator door drive structure includes a top sill 1. A drive motor 2 is fixedly connected to one side of the inner wall of the top sill 1. A rotating shaft 3 is fixedly connected to the output end of the drive motor 2. One end of the rotating shaft 3 away from the output end of the drive motor 2 is rotatably connected to the inner wall of the other end of the top sill 1. A drive wheel 4 is fixedly sleeved on the outer surface of the rotating shaft 3. A transmission belt 5 is drivenly connected to the surface of the drive wheel 4. A bidirectional screw 6 is rotatably connected between the two inner walls of the top sill 1 located on one side of the rotating shaft 3. A driven wheel 7 is fixedly sleeved on the surface of the bidirectional screw 6. The side of the transmission belt 5 away from the drive wheel 4 is drivenly connected to the surface of the driven wheel 7. The bidirectional screw 6 is connected to the driven wheel 7. The device is equipped with a threaded block 8, and a movable rod 9 is fixedly connected to the bottom of the threaded block 8. A strip-shaped through hole 10 is opened at the bottom of the top sill 1. The movable rod 9 passes through the strip-shaped through hole 10 and is slidably connected to the strip-shaped through hole 10. An elevator door 11 is fixedly connected to the end of the movable rod 9 away from the threaded block 8. When the drive motor 2 is started, the rotating shaft 3 is rotated, which in turn drives the drive wheel 4 to rotate. This drives the driven wheel 7 to rotate through the transmission belt 5, which in turn drives the bidirectional screw 6 to rotate, which in turn drives the threaded blocks 8 on both sides to move. This, in turn, drives the elevator door 11 to move through the movable rod 9, thus enabling convenient relative or opposite movement of the two elevator doors 11.

[0022] Elevator door 11 is symmetrically connected to a connecting rod 12 at its bottom. A movable seat 13 is fixedly connected to the bottom of the connecting rod 12. Side balls 14 are symmetrically rolled on the outer wall of the movable seat 13. Rollers 15 are rotatably connected between the inner walls of the movable seat 13. A bottom sill 16 is provided at the bottom of the roller 15. Evenly distributed balls 17 are rolled on the bottom of the bottom sill 16. The bottom of the roller 15 is also driven to move on the top of the balls 17, which reduces the friction when the roller 15 moves and facilitates the sliding of the elevator door 11. The side balls 14 move inside the side groove 18 to limit and guide the roller 15, which facilitates the rapid sliding of the two elevator doors 11.

[0023] The drive wheel 4 is larger than the driven wheel 7, so that when the drive wheel 4 rotates, it drives the driven wheel 7 to rotate through the transmission belt 5.

[0024] The inner wall of the bottom sill 16 is symmetrically provided with side grooves 18 on both sides. The side beads 14 are rolled inside the side grooves 18. Through the side beads 14 and the side grooves 18, the roller 15 can be limited and guided.

[0025] The roller 15 has an inner groove 19 in the middle, and the top of the ball 17 is located inside the inner groove 19. By setting the inner groove 19 and the ball 17, the friction of the roller 15 when it moves is reduced.

[0026] The bottom of the sill 16 is fixedly connected with evenly distributed mounting blocks 20, and bolts 21 are threaded onto the mounting blocks 20. By setting the mounting blocks 20 and bolts 21, the sill 16 can be easily installed.

[0027] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
