Description

Technical Field

[0001] This utility model belongs to the field of elevator equipment technology, and in particular relates to an elevator ceiling component. Background Technology

[0002] With the rapid development of modern urbanization, high-rise buildings are increasing in number. As an indispensable vertical transportation tool in high-rise buildings, elevators have received increasing attention for their safety, comfort, and aesthetics.

[0003] Existing elevator ceiling systems use fans installed at the top to draw in outside air and blow it out along the perimeter of the ceiling. During this airflow, the air passes through multiple filter plates, which remove dust and other pollutants.

[0004] After the above equipment is completed, the filter plate is easily clogged with dust during long-term use, and the filter plate is located inside the device and is difficult to remove for cleaning, which leads to a decrease in the filtration efficiency of the filter plate. Therefore, we propose a component for elevator ceiling. Utility Model Content

[0005] The purpose of this utility model is to provide an elevator ceiling assembly that solves the problem that the filter plate is easily clogged with dust during long-term use, and the filter plate is difficult to remove and clean because it is located inside the device, thus reducing the filtration efficiency of the filter plate.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a component for elevator ceiling installation, including a fixing box, wherein a connecting plate is fixedly connected to the bottom outer wall of the fixing box;

[0008] The inner wall of the fixed box is provided with a cleaning mechanism, which includes a fan. The outer wall of the fan is fixedly connected to the inner wall of the fixed box. A connecting shaft is fixedly connected to the bottom outer wall of the fan. Several connecting rods are fixedly connected to the outer wall of the connecting shaft away from the fan. A scraper is fixedly connected to the outer wall of the other end of the connecting rod. The outer wall of the scraper is slidably connected to the inner wall of the filter cartridge. A limit block is slidably connected to the outer wall of the filter cartridge. The outer wall of the limit block is fixedly connected to the inner wall of the fixed box. A ventilation pipe is fixedly connected to the outer wall of the limit block. Several connecting blocks are fixedly connected to the outer wall of the filter cartridge.

[0009] Furthermore, the inner wall of the limiting block is provided with a plurality of limiting grooves, the inner wall of the limiting grooves is slidably connected to the outer wall of the connecting block, a plurality of pressure springs are fixedly connected to the inner wall of the limiting block, a locking block is fixedly connected to the outer wall of the end of the pressure spring away from the limiting block, the outer wall of the locking block is engaged with the inner wall of the connecting block, and a ventilation mechanism is provided on the outer wall of the connecting plate.

[0010] Furthermore, the ventilation mechanism includes a second ventilation pipe, the outer wall of which is fixedly connected to the outer wall of the limiting block, and a positioning frame is fixedly connected to the inner wall of the second ventilation pipe.

[0011] Furthermore, a positioning rod is rotatably connected to the outer wall of the positioning frame, a fan blade is fixedly connected to the outer wall of the positioning rod near the positioning frame, and a fixing plate is fixedly connected to the outer wall of the positioning rod away from the positioning frame.

[0012] Furthermore, a second positioning rod is rotatably connected to the outer wall of the fixed plate, and a plurality of fixed rods are rotatably connected to the outer wall of the second positioning rod. A hollow rod is rotatably connected to the outer wall of the fixed rod away from the second positioning rod, and a limit rod is slidably connected to the inner wall of the hollow rod.

[0013] Furthermore, an air outlet pipe is fixedly connected to the outer wall of the limiting rod, and the outer wall of the air outlet pipe is fixedly connected to the outer wall of the second ventilation pipe. The outer wall of the hollow rod is connected to a ring, and a plurality of limiting rods are fixedly connected to the outer wall of the connecting ring. A connecting rod is rotatably connected to the outer wall of the limiting rod.

[0014] Furthermore, a positioning rod three is rotatably connected to the top outer wall of the connecting rod two, the outer wall of the positioning rod three is fixedly connected to the inner wall of the air outlet pipe, and a fan blade two is fixedly connected to the bottom outer wall of the connecting rod two.

[0015] Furthermore, a lower positioning box is fixedly connected to the bottom outer wall of the connecting plate, the outer wall of the lower positioning box is fixedly connected to the outer wall of the air outlet pipe, a ventilation groove is opened on the inner wall of the lower positioning box, and several grid plates are fixedly connected to the bottom outer wall of the lower positioning box.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a filter cylinder and a connecting block. After the filter cylinder is pushed back to its original position and rotated in the opposite direction, the connecting block and the limiting block overlap. During the movement of the connecting block, the connecting block pushes the locking block inside the limiting block, causing the locking block to press the pressure spring on the rear side. The elasticity of the pressure spring pushes the locking block to move while simultaneously locking the connecting block, thus quickly connecting the filter cylinder and the limiting block. This achieves the goal of locking the connecting block by rotating the filter cylinder, preventing the filter plate from being easily clogged by dust during long-term use, and avoiding the problem of reduced filtration efficiency caused by the filter plate being located inside the device and difficult to remove for cleaning.

[0018] 2. This utility model incorporates a hollow rod and a positioning rod three. When the air generated by the fan enters the ventilation duct two, it pushes the fan blades, causing the positioning rod to rotate around the interior of the positioning frame. This, in turn, causes the positioning rod to rotate the fixing plate at the other end. Simultaneously, the fixing plate, by rotating the positioning rod two, pulls the fixing rods at both ends back and forth. During the movement of the fixing rods, the hollow rod is pushed to move, which in turn pulls the connecting ring to move. This, in turn, causes the connecting rod two to move, resulting in the connecting rod two swaying left and right around the positioning rod three. This swaying of the connecting rod two causes the fan blades two at the bottom to sway back and forth. This achieves the goal of changing the direction of the fan blades two by moving the positioning rod three, thus preventing problems such as stuffiness caused by poor air circulation in the elevator when it is crowded with passengers during certain periods, as the ventilation openings are located on the periphery and cannot reach the center.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 As shown, this utility model is a component for elevator ceiling installation, including a fixing box 1. A connecting plate 101 is fixedly connected to the bottom outer wall of the fixing box 1, and the fixing box 1 is connected to the lower positioning box 316 through the connecting plate 101.

[0030] The inner wall of the fixed box 1 is equipped with a cleaning mechanism 2, which includes a fan 201, model ClaugCFZ, which is designed to balance quiet operation and ventilation efficiency. Employing a special blade design and noise reduction technology, the fan generates extremely low noise during operation, ensuring passenger comfort even in relatively confined spaces like elevator cars. The outer wall of the fan 201 is fixedly connected to the inner wall of the fixed box 1. A connecting shaft 202 is fixedly connected to the bottom outer wall of the fan 201. Several connecting rods 203 are fixedly connected to the outer wall of the end of the connecting shaft 202 furthest from the fan 201. A scraper 204 is fixedly connected to the outer wall of the other end of the connecting rods 203. Rotation of the fan 201 drives the connecting shaft 202 to rotate, simultaneously rotating the scraper 204 on the outer side of the connecting rods 203. The outer wall of the scraper 204 is slidably connected to the inner wall of the filter cartridge 205. Because the outer wall of the scraper 204 fits snugly against the inside of the filter cartridge 205, the rotation of the scraper 204 removes dust from inside the filter cartridge 205. A limiting block 206 is slidably connected to the outer wall of the filter cartridge 205. The outer wall of the limiting block 206 is fixedly connected to the inner wall of the fixed box 1. A ventilation pipe 207 is fixedly connected to the outer wall of the filter cylinder 205. Several connecting blocks 208 are fixedly connected to the outer wall of the filter cylinder 205. Several limiting grooves 209 are formed on the inner wall of the limiting block 206. The inner wall of the limiting groove 209 is slidably connected to the outer wall of the connecting block 208. By sliding the connecting block 208 in the limiting groove 209, the filter cylinder 205 is quickly connected to the limiting block 206. Several pressure springs 210 are fixedly connected to the inner wall of the limiting block 206. A locking block 211 is fixedly connected to the outer wall of the end away from the limiting block 206. The outer wall of the locking block 211 engages with the inner wall of the connecting block 208. When the connecting block 208 slides along the inside of the limiting groove 209, the connecting block 208 will overlap with the limiting block 206, and the connecting block 208 will push the locking block 211 while squeezing the pressure spring 210. The elasticity of the pressure spring 210 will push the locking block 211 to lock the connecting block 208. The outer wall of the connecting plate 101 is provided with a ventilation mechanism 3.

[0031] The ventilation mechanism 3 includes a second ventilation duct 301. The outer wall of the second ventilation duct 301 is fixedly connected to the outer wall of the limiting block 206. A positioning frame 302 is fixedly connected to the inner wall of the second ventilation duct 301. A positioning rod 304 is rotatably connected to the outer wall of the positioning frame 302. A fan blade 303 is fixedly connected to the outer wall of the positioning rod 304 near the positioning frame 302. The air generated by the fan 201 is sent out through the second ventilation duct 301, and the fan blade 303 is blown to drive the positioning rod 304 to rotate. A fixing plate 305 is fixedly connected to the outer wall of the end of the positioning rod 304 away from the positioning frame 302. A second positioning rod 306 is rotatably connected to the outer wall of the fixing plate 305. Several fixing rods 307 are rotatably connected to the outer wall of the second positioning rod 306. The rotation of the positioning rod 304 causes the fixing plate 305 to rotate, which in turn causes the positioning rod 306 to rotate. Since the positioning rod 306 is fixed to a part away from the center of the fixing plate 305, the rotation area of ​​the positioning rod 306 is larger than that of the fixing plate 305. Therefore, when the positioning rod 306 rotates, it will continuously pull the fixing rods 307 on both sides of the positioning rod 306. The outer wall of the fixed rod 307 away from the positioning rod 306 is rotatably connected to the hollow rod 308. The inner wall of the hollow rod 308 is slidably connected to the limiting rod 309. During the movement of the fixing rod 307, the hollow rod 308 will be pulled to move. However, the interior of the hollow rod 308 is restricted by the limiting rod 309. Therefore, the hollow rod 308 can only slide along the limiting rod 309.

[0032] An air outlet pipe 310 is fixedly connected to the outer wall of the limiting rod 309. The outer wall of the air outlet pipe 310 is fixedly connected to the outer wall of the second ventilation pipe 301. A connecting ring 311 is connected to the outer wall of the hollow rod 308. Several limiting rods 312 are fixedly connected to the outer wall of the connecting ring 311. The movement of the hollow rod 308 pulls the connecting ring 311 to move, which in turn drives the connecting rods 313 inside the connecting ring 311 to move. The connecting rods 313 are rotatably connected to the outer wall of the limiting rods 312. The top outer wall of the connecting rods 313 is rotatably connected to the positioning rods 314. The outer wall of the positioning rods 314 is fixedly connected to the inner wall of the air outlet pipe 310. Since the top of the connecting rods 313 is restricted by the positioning rods 314, when the connecting ring 311 pulls the connecting rods 313 to move, the connecting rods 313 can only move around the connecting ring 311. The positioning rod 314 rotates, and the bottom outer wall of the connecting rod 313 is rotatably connected to the fan blade 315. The rotation of the connecting rod 313 causes the bottom fan blade 315 to swing back and forth. At the same time, the fan blade 315 will rotate due to the air from the air outlet 310. Therefore, the direction of the air can be changed by the shaking of the fan blade 315. The bottom outer wall of the connecting plate 101 is fixedly connected to the lower positioning box 316. The outer wall of the lower positioning box 316 is fixedly connected to the outer wall of the air outlet 310. The inner wall of the lower positioning box 316 is provided with a ventilation slot 317. Several grid plates 318 are fixedly connected to the bottom outer wall of the lower positioning box 316. The air in the ventilation pipe 207 and the air in the ventilation pipe 301 are sent out from the surroundings of the device through the grid plates 318.

[0033] One specific application of this embodiment is:

[0034] When staff need to use the equipment, it is installed on the elevator. Then, the fan 201 is started to draw air from the elevator shaft into the device. Since a filter cartridge 205 is located directly below the fan 201, the air drawn in by the fan 201 comes into contact with the filter cartridge 205, which filters the air. The filtered air is then sent to the outside of the device through ventilation pipes 207 and 301, and exited through ventilation slots 317 around the device. Simultaneously, four grille plates 318 installed at the bottom of the device effectively prevent external objects from entering. During the rotation of the fan 201, the connecting shaft 202 rotates, and the rotation of the connecting shaft 202 drives multiple connecting rods 203. As the filter cylinder rotates, the scraper 204 also rotates. Due to the length of the connecting rod 203, the scraper 204 fixed at the outermost end of the connecting rod 203 will contact the inside of the filter cylinder 205. Therefore, the rotation of the scraper 204 will scrape away the dust inside the filter cylinder 205. After the dust accumulates in the filter cylinder 205 for a certain period of time, the filter cylinder 205 can be rotated to drive multiple connecting blocks 208 to slide along the limiting groove 209 inside the limiting block 206. At the same time, after the connecting blocks 208 no longer overlap with the limiting block 206, the filter cylinder 205 can be moved downwards to remove it. The inside of the filter cylinder 205 can then be cleaned. Afterwards, the filter cylinder 205 is pushed back to its original position and rotated in the opposite direction, so that the connecting blocks 208 and the limiting blocks 206... 06 overlaps. During the movement of connecting block 208, connecting block 208 pushes the locking block 211 inside limiting block 206, causing locking block 211 to squeeze the pressure spring 210 on the rear side. The elasticity of pressure spring 210 pushes locking block 211 to move, while locking block 211 locks connecting block 208, thus allowing filter cartridge 205 to quickly connect with limiting block 206. When the air generated by fan 201 enters ventilation duct 201, it pushes fan blade 303, causing positioning rod 304 to rotate around the inside of positioning frame 302, and causing positioning rod 304 to drive the fixing plate 305 at the other end to rotate. At the same time, the fixing plate 305 drives positioning rod 206 to rotate. Since positioning rod 206 is fixed away from the center of fixing plate 305... The position of the positioning rod 306 is such that its rotation area is larger than that of the fixed plate 305. Since the positioning rod 306 is connected to the fixed plate 305 via its middle section, its rotation pulls the fixed rods 307 at both ends back and forth. During the movement of the fixed rods 307, the hollow rod 308 is pushed to move. Because a limiting rod 309 is inserted into the hollow section of the hollow rod 308 and is fixed inside the ventilation pipe 301, the movement range of the hollow rod 308 is limited by the limiting rod 309. Simultaneously, the movement of the hollow rod 308 pulls the connecting ring 311, which in turn drives the connecting rod 313 to move. Since the top of the connecting rod 313 is limited by the positioning rod 314, the movement of the connecting rod 313 is restricted.Therefore, when the connecting ring 311 moves the connecting rod 313, the connecting rod 313 will sway left and right around the positioning rod 314. Simultaneously, the swaying of the connecting rod 313 will cause the bottom fan blades 315 to sway back and forth. Since the outlet pipe 310 is connected to the ventilation pipe 301, some air from the ventilation pipe 301 will be sent into the outlet pipe 310, causing the air to drive the multiple fan blades 315 to rotate. The rotation of the fan blades 315 will then blow the air out. Furthermore, the swaying of the fan blades 315 changes the direction of the airflow, thereby increasing the airflow range.
