Description

Technical Field

[0001] This utility model relates to a viewing platform, and more particularly to a liftable viewing platform. Background Technology

[0002] Viewing platforms are commonly used in scenic areas to allow tourists to enjoy the view from a suitable height. However, existing viewing platforms have limited heights, resulting in a limited field of vision. Building taller viewing platforms would make it difficult for users to get on and off. In addition, since the height of existing viewing platforms is fixed, and different tourists have different heights, tourists cannot adjust to a suitable viewing height during the viewing process, resulting in a poor viewing experience.

After viewing, the platform descends to its lowest position, allowing people to dismount. In the event of a power outage or other uncontrolled descent, the buffer mechanism provides cushioning for the slide, reducing the impact upon hitting the bottom. Compared to a fixed observation platform, this design allows for adjustable viewing height. Attached Figure Description

Figures 1-6As shown, the lifting observation deck includes: a base 1, a connecting seat 2, a lead screw 3, a motor 4, a slide 5, a buffer mechanism 6, and an observation deck 7. The connecting seat 2 is vertically fixed to the base 1. A sliding groove is provided on the side wall of the connecting seat 2, and the sliding groove is perpendicular to the ground. The lead screw 3 is located in the sliding groove. The top end of the lead screw 3 is rotatably connected to the top end of the connecting seat 2, and the bottom end of the lead screw 3 is rotatably connected to the bottom end of the connecting seat 2. The motor 4 is fixed to the connecting seat 2, and the rotating shaft of the motor 4 is coaxially connected to any end of the lead screw 3. A threaded hole is provided through the middle of the slide 5, and the threaded hole is threadedly connected to the lead screw 3. The two sides of the slide 5 are slidably connected to the inner side wall of the sliding groove. A buffer mechanism 6 is provided at the bottom end of the sliding groove. The slide 5 can squeeze the buffer end of the buffer mechanism 6. The observation deck 7 is fixed to the slide 5. The lead screw 3 can rotate under the drive of the motor 4, and the observation deck 7 can move back and forth along the sliding groove under the drive of the motor 4. In operation, the observation platform 7 is initially in its lowest position, facilitating easy access for personnel. Once a person stands on the platform, the motor 4 drives the lead screw 3 to rotate, thus raising the platform. The height of the platform can be adjusted according to the person's height and viewing needs. After viewing, the platform descends to its lowest position, allowing the person to dismount. In the event of a power outage or other uncontrolled descent, the buffer mechanism 6 provides cushioning for the slide 5, reducing the impact upon bottoming out. Compared to a fixed observation platform, the platform's height can be adjusted as needed, offering the advantage of adjustable viewing height.

[0026] Optionally in this embodiment, the top end of the connecting seat 2 is provided with a first connecting hole, and the first bearing is disposed in the first connecting hole. The bottom end of the connecting seat 2 is provided with a second connecting hole, and the second bearing is disposed in the second connecting hole. The top end of the lead screw 3 is connected to the inner ring of the first bearing, and the bottom end of the lead screw 3 is connected to the inner ring of the second bearing. The motor 4 is fixed to the top of the connecting seat 2, and the rotation shaft of the motor 4 is coaxially connected to the top end of the lead screw 3.

[0027] Optionally in this embodiment, the base 1 is provided with a drive mechanism and a counterweight. The drive mechanism is electrically connected to the motor 4, and a controller is also electrically connected to the drive mechanism. The controller is provided with buttons for controlling the rise, fall and stop of the viewing platform 7.

An electromagnetic brake is also provided at the rear end of the servo motor, which can fix or release the rotating shaft of the servo motor. The servo motor, reducer, and electromagnetic brake are all commercially available products. In this embodiment, the electromagnetic brake is a type that locks after a power outage. When an unexpected power outage occurs, the rotating shaft of the servo motor can be locked by the electromagnetic brake, thus reducing the probability of the observation deck 7 descending uncontrollably due to a power outage.

[0033] Optionally in this embodiment, a rubber buffer pad 8 is provided on the top surface of the base 1, and the bottom surface of the fixing plate 72 can abut against the top surface of the rubber buffer pad 8. When the observation deck 7 descends uncontrollably, the rubber buffer pad 8 can provide cushioning to reduce the impact force when the fixing plate 72 and the base 1 collide with each other, thereby reducing the probability of equipment damage and protecting the personnel on the observation deck 7.

[0034] Optionally in this embodiment, the hydraulic buffer rod 61 is perpendicular to the ground, and the top of the buffer block 62 has a notch into which the roller 53 can be inserted.
