[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Please see Figures 1-5 As shown, this utility model provides a technical solution: a variable speed intelligent revolving door, including a rotating plate 1, a rotating rod 2 fixedly connected to the bottom of the rotating plate 1, a cleaning component 3 installed on the outer wall of the rotating rod 2, and a lifting component 4 provided inside the rotating rod 2;
[0025] The cleaning assembly 3 includes three rotating door bodies 301 connected to the outer wall of the rotating rod 2 by equidistant screws. Each of the three rotating door bodies 301 has an installation groove 302 on its outer wall. The inner wall of each of the three installation grooves 302 is rotatably connected to a threaded rod 303 via a bearing. The outer wall of each of the three threaded rods 303 is threadedly connected to a lifting plate 304. The inner wall of each of the three lifting plates 304 is symmetrically fitted with a cleaning cloth 305. The outer wall of the cleaning cloth 305 is in contact with the outer wall of the rotating door body 301. The three threaded rods 303 penetrate the rotating disk and are fixedly connected to gears 306. The outer walls of the three gears 306 are meshed with a toothed belt 307. The top of the rotating plate 1 is fixedly connected to a support frame 308. The inner wall of the support frame 308 is equipped with a driving component for driving the threaded rods 303.
[0026] In use, when the rotating rod 2 drives the rotating plate 1 to rotate, the driving component drives the threaded rod 303 to rotate. The threaded rod 303 causes the lifting plate 304 to move up and down along the revolving door body 301 through threaded transmission. The cleaning cloth 305 on the lifting plate 304 wipes the outer wall of the revolving door body 301. At the same time, the gear 306 meshes with the toothed belt 307 to ensure that the three threaded rods 303 rotate synchronously and that the cleaning cloth 305 rises and falls synchronously, realizing automatic cleaning of the outer wall of the revolving door body 301 without manual operation, improving cleaning efficiency. The cleaning cloth 305 can move up and down to cover the entire outer wall of the revolving door body 301, making cleaning more comprehensive.
[0027] More specific solutions, such as Figure 2 as well as Figure 3 The driving component includes a motor 309 fixedly connected to the inner wall of the support frame 308, and the output end of the motor 309 is fixedly connected to the top of the threaded rod 303.
[0028] In use, the motor 309 is installed on the inner wall of the support frame 308, and its output end is directly fixed to the top of the threaded rod 303. After the motor 309 is powered on, it rotates, driving the threaded rod 303 to rotate, thereby driving the lifting plate 304 and the cleaning cloth 305 to move. The motor 309 serves as the driving source, providing stable power to ensure the normal operation of the cleaning component 3. It has a simple structure, is easy to install, and is convenient to maintain and replace.
[0029] In a more preferred embodiment, such as Figure 4 as well as Figure 5 The lifting assembly 4 includes an electric push rod 401 fixedly connected to the inner wall of the rotating rod 2. The outer wall of the rotating rod 2 is provided with three equidistant limiting grooves 402. The output end of the electric push rod 401 is fixedly connected to a fixing block 403. The outer wall of the fixing block 403 is fixedly connected with three baffles 404 at equidistant intervals. The outer walls of the three baffles 404 are slidably connected to the inner walls of the limiting grooves 402. Each of the three baffles 404 has a limiting block 405 fixedly connected to its outer wall.
[0030] In use, the electric push rod 401 is fixed to the inner wall of the rotating rod 2. After being powered on, it pushes the fixed block 403 to move. The fixed block 403 drives the baffle 404 to slide along the limiting groove 402. The limiting block 405 on the baffle 404 slides in the sliding groove, realizing the lifting and lowering of the baffle 404. The lifting and lowering of the baffle 404 can be controlled by the electric push rod 401. The position of the baffle 404 can be adjusted as needed to achieve different functions. For example, when the baffle 404 is lowered, it can play a certain blocking role. The setting of the limiting groove 402 and the sliding groove ensures the stability and accuracy of the movement of the baffle 404.
[0031] In a more preferred embodiment, such as Figure 4 as well as Figure 5The bottom of each of the three baffles 404 is fixedly connected to a floor brush 406, and the top of each of the three floor brushes 406 is attached with a magnetic strip 407.
[0032] During use, the floor brush 406 at the bottom of the baffle 404 rises and falls with the baffle 404. When the baffle 404 descends to the ground, the floor brush 406 contacts the ground. When the revolving door rotates, the floor brush 406 can sweep the dust on the ground and can automatically rise and quickly pull away in case children get their hands caught. The magnetic strip 407 is magnetically connected to the baffle 404 (magnetically coated steel plate), so that the floor brush 406 is fixed on the baffle 404. The setting of the floor brush 406 increases the cleaning function of the revolving door body 301, and can clean the ground at the same time. The magnetic connection makes it easy to install and remove the floor brush 406, and facilitates replacement and maintenance.
[0033] In a more preferred embodiment, such as Figure 1 as well as Figure 2 The bottom of each of the three revolving door bodies 301 is provided with a sliding groove, the inner wall of the three sliding grooves is slidably connected to the outer wall of the baffle 404, and the outer wall of the three limiting blocks 405 is slidably connected to the inner wall of the sliding groove.
[0034] During use, the sliding groove at the bottom of the revolving door body 301 slides in conjunction with the outer wall of the baffle 404, and the limiting block 405 slides within the sliding groove. When the baffle 404 rises or falls, the sliding groove and the limiting block 405 act as guides and limiters, ensuring that the relative position of the baffle 404 and the revolving door body 301 is accurate. The cooperation between the sliding groove and the limiting block 405 makes the connection between the baffle 404 and the revolving door body 301 more stable, preventing the baffle 404 from shifting or shaking during movement, and ensuring the normal operation of the entire device.
[0035] In a more preferred embodiment, such as Figure 4 as well as Figure 5 The baffle 404 is a magnetically coated steel plate, and the tops of the three magnetic strips 407 are magnetically connected to the top of the inner wall of the baffle 404.
[0036] In use, the baffle 404 is a magnetically coated steel plate, and the magnetic strip 407 is magnetically connected to the top of the inner wall of the baffle 404, so that the floor brush 406 is firmly installed on the baffle 404 and is easy to disassemble. The magnetic connection method is simple and reliable, requiring no additional fasteners, reducing costs, facilitating the replacement and maintenance of the floor brush 406, and improving the practicality of the device.
[0037] In a more preferred embodiment, such as Figure 1 as well as Figure 4 The outer walls of the three revolving door bodies 301 are all provided with guide grooves, and the outer walls of the three lifting plates 304 are all fixedly connected with guide blocks. The outer walls of the three guide blocks are slidably connected to the inner walls of the guide grooves.
[0038] During use, the guide groove on the outer wall of the revolving door body 301 slides in conjunction with the guide block on the lifting plate 304. When the lifting plate 304 moves up and down along the threaded rod 303, the guide block slides in the guide groove, which plays a guiding role and prevents the lifting plate 304 from rotating. This ensures that the cleaning cloth 305 is in close contact with the outer wall of the revolving door body 301. The design of the guide groove and guide block ensures the smoothness and accuracy of the movement of the lifting plate 304, allowing the cleaning cloth 305 to wipe the outer wall of the revolving door body 301 evenly and improve the cleaning effect.
[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
