Description

Technical Field

[0001] This utility model belongs to the field of elevator blackout curtain technology, specifically a blackout curtain for sightseeing elevator cars. Background Technology

[0002] A sightseeing elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin, used for transporting passengers or goods in multi-story buildings. One or more walls of the shaft and car are made of transparent material, allowing passengers to view the scenery outside the car. At least one side of the shaft and car walls is transparent, allowing passengers to see the outside scenery. Existing sightseeing elevators typically use roller blinds, where the rollers roll up the entire blind. Rolling up the entire blind puts the rollers under the weight of the entire blind, making them prone to breakage and putting the motor under load, thus shortening the blind's lifespan. Furthermore, after prolonged use, the blinds need to be cleaned and replaced, but roller blinds are cumbersome to disassemble and install, increasing the workload for users. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a blackout curtain for sightseeing elevator cars. It solves the problem that in some sightseeing elevator blackout curtains, the rollers in roller-type curtains roll up the entire curtain. After rolling up the entire curtain, the rollers bear the weight of the entire curtain, which makes the rollers prone to breakage and the motor under load, thus shortening the service life of the blackout curtain. At the same time, after long-term use, the curtains need to be cleaned and replaced, but roller-type curtains are cumbersome to disassemble and install, thus increasing the workload for users.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a blackout curtain for a sightseeing elevator car, comprising a connecting seat, a transmission groove at the bottom of the connecting seat, a lead screw in the transmission groove, transmission blocks threaded to both ends of the lead screw, a barb fixedly connected to the bottom of the transmission block, a first rotating gear fixedly connected to one end of the lead screw, a second rotating gear meshing with the outer side of the first rotating gear, a connecting column fixedly connected to the bottom of the second rotating gear, a connecting block on the outer side of the connecting column, a first bevel gear fixedly connected to the bottom of the connecting column, a second bevel gear meshing with the outer side of the first bevel gear, a support column fixedly connected inside the second bevel gear, the support column passing through one end of the connecting block, a turntable fixedly connected to one end of the support column, and a rocker arm fixedly connected to one end of the turntable.

[0005] As a further embodiment of this utility model: the bottom two ends of the connecting seat are fixedly connected to cabinets, and one of the cabinets is fixedly connected to one side of the connecting block.

[0006] As a further embodiment of this utility model: one end of the cabinet is provided with a cabinet door, and the top and bottom of one end of the cabinet are fixedly connected with hinges, and the cabinet door is hinged to the cabinet by the hinges.

[0007] As a further embodiment of this utility model: a handle is fixedly connected to one end of the cabinet door, and a sliding groove is provided on one side of the cabinet body, with a curtain installed inside the sliding groove.

[0008] As a further embodiment of this utility model: limit holes are provided at both ends of the top of the curtain, a fixing ring is fixedly connected inside the limit hole, a hook is provided inside the fixing ring, and the other end of the hook is set in the barb.

[0009] As a further embodiment of this utility model: the top two ends of the connecting seat are fixedly connected to fixing blocks, one end of the fixing block is provided with a fixing hole, and a bolt is threaded into the fixing hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The sightseeing elevator car uses blackout curtains. By incorporating a turntable, rocker arm, first bevel gear, second bevel gear, and connecting column, when the curtains are needed, the rocker arm is first used to rotate the turntable. The turntable rotates the supporting column, which in turn rotates the second bevel gear. The second bevel gear rotates the first bevel gear, which in turn rotates the connecting column. The connecting column then rotates the second rotating gear, which in turn rotates the first rotating gear. The first rotating gear rotates the lead screw, which in turn moves the transmission block. The transmission block moves the barb, which in turn moves the hook, which in turn moves the fixing ring, which in turn moves the curtain, thus opening the curtain. This improves efficiency and convenience for users.

[0012] 2. The sightseeing elevator car uses blackout curtains. By installing handles, hinges, hooks, fixing rings, and the curtain itself, when the curtain needs to be installed, first, by holding the handle and applying force to one end, the door is rotated open along the hinges. Then, the fixing ring at the top of the curtain is fitted into the hook, and then one end of the hook is fitted into the fixing ring at the top of the cabinet. Next, the other end of the curtain is passed through a groove on one side of the cabinet, and the top fixing ring is fitted into a hook via the hook. The curtain is now installed. When the curtain is not in use, the hook can be moved by a transmission block, which in turn moves the hook, which in turn moves the fixing ring, and finally the curtain, allowing it to be stored inside the cabinet. This improves the effectiveness of the blackout curtain. Attached Figure Description
