Description

Technical Field

[0001] This utility model relates to the field of elevator car maintenance technology, and in particular to an elevator car that is easy to maintain. Background Technology

[0002] With the acceleration of urbanization, elevators have become an indispensable vertical transportation tool in high-rise buildings, and the importance of cleaning and maintaining the car buttons, which are frequently used components, is becoming increasingly prominent.

[0003] The existing elevator car uses laser sensors in conjunction with baffles inside the shaft to detect its position and speed. However, the laser sensors are installed on the outside of the elevator car. When the sensors malfunction or are damaged, it is necessary to manually enter the shaft to replace or repair them. Entering the shaft requires maintenance personnel to wear a lot of safety equipment, making the maintenance work cumbersome.

[0004] The existing patent (publication number: CN216613615U) discloses an elevator position detection device that is easy to maintain. The beneficial effect of this utility model is that when the laser sensor on the outside of the elevator car malfunctions or is damaged, the maintenance personnel can enter the car to replace the laser sensor without having to enter the shaft for maintenance work, thus improving maintenance efficiency.

[0005] To address the aforementioned issues, existing patents offer solutions. Currently, many elevator car buttons feature a raised design, which, especially in densely populated areas such as hospitals, schools, and shopping malls, makes the button surface a potential medium for the cross-transmission of bacteria and viruses. When cleaning elevator car buttons in different areas of public places in large quantities, staff need to use hand sanitizer and cleaning cloths to spray disinfectant and then wipe them. If the cloths or disinfection tools are not replaced in time, cross-area contamination may occur, and staff are likely to come into contact with a large number of bacteria, posing a certain threat to their health.

[0006] Therefore, an elevator car that is easy to maintain is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide an elevator car that is easy to maintain. It can solve the problem that the buttons in some existing elevator cars are mostly raised, especially in densely populated places such as hospitals, schools, and shopping malls. The surface of the buttons becomes a potential medium for the cross-transmission of bacteria and viruses. When cleaning elevator car buttons in different areas of public places in large quantities, staff need to spray disinfectant and wipe them with a cleaning cloth. If the cloth or disinfection tools are not replaced in time, cross-area contamination may occur. In addition, staff are likely to come into contact with a lot of bacteria, which poses a certain threat to the health of the staff.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an elevator car that is easy to maintain, comprising an elevator car body and several buttons, wherein a slide rail is fixedly connected to the right side of the inner wall of the elevator car body, a sliding wiping mechanism is provided on the front side of the buttons, and a spraying mechanism is provided at the bottom of the sliding wiping mechanism.

[0009] The sliding wiping mechanism includes a fixed plate, a wiping block, a sliding plate, two limiting rings and two limiting posts. The front side of the wiping block is fixedly connected to the rear side of the fixed plate, and the rear side of the limiting post is fixedly connected to the front side of the fixed plate. The limiting ring is threaded onto the surface of the limiting post, and the rear side of the limiting ring is in close contact with the front side of the sliding plate.

[0010] Preferably, the spraying mechanism includes an inlet pipe, a plurality of atomizing nozzles and a fixed pipe, wherein the rear side of the inlet pipe is fixedly connected to the front side of the fixed pipe, and the front side of the atomizing nozzles is fixedly connected to the rear side of the fixed pipe.

[0011] Preferably, connecting blocks are fixedly connected to both sides of the top of the fixed tube, and the top of the connecting blocks is fixedly connected to the bottom of the slide plate.

[0012] Preferably, a pull ring is fixedly connected to the bottom of the fixing tube.

[0013] Preferably, the fixing plate has two notches inside, and the limiting post is located inside the notch.

[0014] Preferably, a slider is fixedly connected to the right side of the skateboard, the slider is slidably connected inside the slide rail, and a handle is fixedly connected to the front side of the skateboard.

[0015] Preferably, the fixing plate has a fixing groove inside, and a first magnetic block is fixedly connected inside the fixing groove. A second magnetic block that works in conjunction with the first magnetic block is embedded in the top of the inner wall of the elevator car body.

[0016] Preferably, the bottom and the rear side of the wiping block are chamfered, and the material of the wiping block is memory foam.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application features a sliding wiping mechanism. Through the sliding connection between the slider and the slide rail, the staff can hold the handle and move the memory foam wiping block back and forth along the surface of the button. Its elastic fit and chamfered design can tightly wrap the button protrusions and edges, achieving a fast and comprehensive wiping without dead angles. The detachable structure with the limit ring and notch makes it easy to replace the wiping block. It supports wiping one button with one wiping block, avoiding cross-contamination of bacteria when cleaning across areas. Moreover, the hands do not need to directly touch the buttons, ensuring the safety of the staff.

[0019] 2. This application, by setting up a spraying mechanism, connects the inlet pipe and the fixed pipe to the atomizing nozzle. A container containing disinfectant, equipped with a pump and an extension pipe, is moved into the elevator car body. The extension pipe is connected to the inlet pipe, and after the pump is started, the disinfectant is evenly atomized and sprayed onto the button surface, providing comprehensive coverage. The fixed pipe is rigidly connected to the sliding plate via a connecting block, ensuring that spraying and wiping actions are performed simultaneously, improving cleaning efficiency. The bottom pull ring, in conjunction with the first and second magnetic blocks, allows for remote control of the sliding plate's lifting and fixing to the top of the elevator car body via an external long rod-shaped hook, avoiding manual climbing and reducing maintenance risks.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] An easy-to-maintain elevator car includes an elevator car body 1 and several buttons 3. A slide rail 2 is fixedly connected to the right side of the inner wall of the elevator car body 1. A sliding wiping mechanism 4 is provided on the front side of the buttons 3. A spraying mechanism 8 is provided at the bottom of the sliding wiping mechanism 4.

[0031] The sliding wiping mechanism includes a fixed plate 401, a wiping block 402, a sliding plate 403, two limiting rings 404 and two limiting posts 405. The front side of the wiping block 402 is fixedly connected to the rear side of the fixed plate 401, and the rear side of the limiting post 405 is fixedly connected to the front side of the fixed plate 401. The limiting ring 404 is threaded onto the surface of the limiting post 405, and the rear side of the limiting ring 404 is in close contact with the front side of the sliding plate 403.

[0032] In this embodiment: When cleaning and maintaining the buttons 3 of the elevator car body 1, the staff first moves the external container containing disinfectant, pump, and extension tube into the elevator car body 1, connects the extension tube to the liquid inlet pipe 801, and starts the pump. The atomizing nozzle 802 sprays the disinfectant evenly onto the surface of the buttons 3 of the elevator car body 1. Then, by holding the handle 7, the staff pulls the slide plate 403, and the slider 5 slides in the slide rail 2, which moves the memory foam wiping block 402. Its strong elasticity and fit tightly wrap the raised part of the button 3, and the chamfered design enhances edge cleaning, achieving thorough and rapid wiping and disinfection without touching the buttons 3, thus avoiding bacterial infection. After cleaning, the staff uses the external long rod-shaped hook to push the slide plate 403 to the top, so that the first magnetic block 6 and the second magnetic block 13 attract and fix it. When using it again, the staff pulls the hook. Once the magnetic attraction of ring 10 is released, the wiping block 402 needs to be replaced. To replace the wiping block 402, loosen the limiting ring 404 and remove the limiting post 405. One wiping block 402 is used for each elevator car body 1 button 3, avoiding cross-contamination of bacteria and improving the safety of cleaning and maintenance of the elevator car body 1. This solves the problem that many existing elevator car buttons use a raised design, especially in densely populated places such as hospitals, schools, and shopping malls, where the button surface becomes a potential medium for the cross-transmission of bacteria and viruses. When cleaning elevator car buttons in different areas of public places in large quantities, staff need to hold disinfectant and a cleaning cloth to spray disinfectant and then wipe. If the cloth or disinfection tool is not replaced in time, it may cause cross-area contamination, and staff are likely to come into contact with a lot of bacteria, which poses a certain threat to the health of the staff.

[0033] Specifically, such as Figure 3 As shown, the spraying mechanism 8 includes an inlet pipe 801, a plurality of atomizing nozzles 802 and a fixed pipe 803. The rear side of the inlet pipe 801 is fixedly connected to the front side of the fixed pipe 803, and the front side of the atomizing nozzles 802 is fixedly connected to the rear side of the fixed pipe 803.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, connecting blocks 11 are fixedly connected to both sides of the top of the fixed tube 803, and the top of the connecting blocks 11 is fixedly connected to the bottom of the slide plate 403.

[0035] Specifically, such as Figure 3 As shown, a pull ring 10 is fixedly connected to the bottom of the fixed tube 803.

[0036] In this embodiment: the spraying mechanism 8 achieves uniform atomization spraying of external disinfectant through the connection design of the liquid inlet pipe 801, the fixed pipe 803 and the atomizing nozzle 802, covering the surface of the button 3 without dead corners. The connecting block 11 rigidly connects the fixed pipe 803 and the slide plate 403 to ensure that the spraying and wiping actions are synchronized, thereby improving cleaning efficiency. The setting of the pull ring 10 makes it easy to move the slide plate 403 with external tools, eliminating the need for manual climbing and reducing maintenance difficulty and safety risks.

[0037] Specifically, such as Figure 2 As shown, the fixed plate 401 has two notches 9 inside, and the limiting post 405 is located inside the notch 9.

[0038] Specifically, such as Figure 2 and Figure 5 As shown, a slider 5 is fixedly connected to the right side of the skateboard 403, and the slider 5 is slidably connected inside the slide rail 2. A handle 7 is fixedly connected to the front side of the skateboard 403.

[0039] In this embodiment, the design of the notch 9 and the limiting post 405 allows the fixing plate 401 to be quickly disassembled and the wiping block 402 to be replaced. The sliding connection structure between the slider 5 and the slide rail 2, combined with the handle 7 design, enables the linear reciprocating motion of the wiping block 402, ensuring that the cleaning trajectory is stable and controllable, improving the cleaning quality while reducing the intensity of operation.

[0040] Specifically, such as Figure 4 and Figure 6 As shown, a fixing groove 12 is provided inside the fixing plate 401, and a first magnetic block 6 is fixedly connected inside the fixing groove 12. A second magnetic block 13, which works in conjunction with the first magnetic block 6, is embedded in the top of the inner wall of the elevator car body 1.

[0041] Specifically, such as Figure 7 As shown, the bottom and back of the wiping block 402 are chamfered, and the material of the wiping block 402 is memory foam.

[0042] In this embodiment, the magnetic attraction of the first magnetic block 6 and the second magnetic block 13 allows the slide plate 403 to be positioned on the top of the elevator car body 1 when not in use, thus avoiding space occupation and affecting passengers. The memory foam wiping block 402, with its chamfered design, can not only fit tightly against the protrusion of the button 3 through elastic deformation, but also effectively clean the edge gaps, significantly improving the disinfection effect. In addition, the material is durable and reusable, reducing maintenance costs.

[0043] Working principle: When cleaning and maintaining the elevator car body 1 buttons 3, the staff first moves the container with disinfectant, equipped with a pump and extension tube, into the elevator car body 1. The extension tube is connected to the inlet pipe 801. After starting the pump, the disinfectant enters the fixed pipe 803 through the inlet pipe 801, and is then evenly sprayed onto the surface of the buttons 3 by the atomizing nozzle 802. Subsequently, the staff holds the handle 7 and pulls the sliding plate 403. The slider 5 slides within the slide rail 2, causing the wiping block 402 to move synchronously, thus quickly and thoroughly wiping and disinfecting the buttons 3. Because the wiping block 402 is made of memory foam, its elasticity... With strong adhesion and a tight fit, it can tightly wrap around the raised part of button 3, improving the cleaning effect. The chamfered design at the bottom and top of the wiping block 402 further enhances the cleaning effect on the edges of button 3. Throughout the process, the staff's hands do not need to directly touch button 3, avoiding the risk of bacterial infection. After cleaning, the staff unplugs the external extension tube and uses the external long rod-shaped hook to push the slide plate 403 upwards until the first magnetic block 6 inside the fixing plate 401 magnetically attracts the second magnetic block 13 on the top of the inner wall of the elevator car body 1. At this point, the slide plate 403 and the wiping block 402 are fixed to the top of the elevator car body 1, without affecting the normal use of the elevator by passengers. When cleaning is required again using the elevator, use a long, rod-shaped hook to pull down the pull ring 10, causing the first magnetic block 6 to detach from the second magnetic block 13. The slide plate 403 can then slide down the slide rail 2 and return to the operable position. Repeat the above disinfection process. When the wiping block 402 needs to be replaced, loosen the limiting ring 404 so that it is no longer in close contact with the slide plate 403. Then, move the fixing plate 401 upwards, causing the limiting post 405 to move out of the notch 9, allowing the wiping block 402 to be replaced. By using one wiping block 402 for cleaning and maintenance through one button 3 on the elevator car body 1, it is possible to avoid damage to the elevator car body. When cleaning and maintaining elevator car buttons (1 and 3) in large quantities and across multiple areas, cross-contamination of bacteria can occur. This solution addresses the issue that many existing elevator car buttons have a raised design, which, especially in densely populated places such as hospitals, schools, and shopping malls, makes the button surface a potential medium for the cross-transmission of bacteria and viruses. When cleaning elevator car buttons in different areas of public places in large quantities, staff need to use hand sanitizer and cleaning cloths to spray disinfectant and then wipe them. If the cloths or disinfection tools are not replaced in time, cross-area contamination may occur, and staff are likely to come into contact with a large number of bacteria, posing a certain threat to their health.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
