Description

Technical Field

[0001] This utility model relates to the field of elevator car ventilation technology, and in particular to a sliding elevator car louver ventilation structure. Background Technology

[0002] The sliding elevator car louver ventilation structure is a ventilation device installed on the elevator car. It controls the opening and closing of the louvers through a sliding mechanism to regulate airflow within the car. Its core lies in using a sliding mechanism to move the louver blades, allowing for adjustment of the blade angle or opening / closing degree as needed, achieving precise control of ventilation volume. It also serves functions such as blocking views and adjusting lighting. This structure remains stable during elevator operation and allows for flexible switching of ventilation states through sliding operation, making it suitable for adjusting the car environment in different scenarios. It provides passengers with a more comfortable airflow experience, and compared to fixed ventilation structures, its sliding design offers advantages in space utilization and ease of operation, making it an important component for improving the comfort of the elevator car environment.

[0003] However, existing sliding elevator car louver structures still have many problems in practical use: Regarding angle adjustment and fixing, traditional structures often use manual levers or simple clips, resulting in poor adjustment precision and difficulty in achieving accurate multi-angle control. Furthermore, they are prone to loosening under elevator vibration, leading to unstable ventilation. In terms of maintenance convenience, existing louver blades and frames are mostly integrated or complexly fixed connections. When blades accumulate dust, become damaged, or age and need cleaning or replacement, the entire louver structure often needs to be dismantled, which is cumbersome and consumes significant manpower and time. For some concealed louvers, even the car's decorative panel must be removed to access the maintenance area, further increasing maintenance difficulty and cost. In addition, existing structures lack effective self-positioning and stabilization mechanisms, making it difficult to maintain stability after angle adjustment. Long-term use can lead to blade wobbling and poor sealing, affecting ventilation performance and potentially generating noise, thus reducing the passenger experience.

[0004] In response to this technical problem, this application proposes a sliding elevator car louver ventilation structure. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing technologies, such as poor angle adjustment accuracy, easy loosening, the need to disassemble the entire window or decorative panel for maintenance, and the lack of a self-positioning mechanism leading to shaking and noise. The proposed structure is a sliding elevator car louver ventilation structure. This structure achieves precise angle adjustment through the linkage of sliding rod, toothed plate, gear and rotating shaft. The angle is fixed and prevented from deviating by the cooperation of spring and positioning plate. The mounting block and rotating shaft are detachable, and the mounting block can be replaced by sliding the blade. Maintenance is convenient and does not require disassembly of the entire window.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A sliding elevator car louver ventilation structure includes a window frame. Multiple rotating shafts are rotatably connected to the left and right sides of the inner wall of the window frame. A gear is fixedly connected to the right side of the right-hand rotating shaft. A sliding groove is formed at the middle of the right side of the outer wall of the window frame. A sliding rod is slidably connected to the inner wall of the sliding groove. A toothed plate is connected to the left end of the sliding rod via a reset assembly. The rear side of the toothed plate meshes with the gear. A positioning plate is fixedly connected to the right side of the outer wall of the window frame. The positioning plate is connected to the sliding rod via a positioning block. A second blade and a first blade are respectively connected to the inner walls of the left and right rotating shafts via mounting blocks. The left inner wall of the first blade is slidably connected to the right end of the outer wall of the second blade. A fixed seat is fixedly connected to the left top side of the first blade, and a sliding seat is fixedly connected to the top side of the second blade. The sliding seat is connected to the fixed seat via a spring assembly.

[0008] Furthermore, the reset assembly includes a limiting ring, which is fixedly connected to the outer left end of the slide rod. A spring is fixedly connected to the left side of the limiting ring, and the other end of the spring is fixedly connected to the inner wall of the toothed plate.

[0009] Furthermore, the outer side of the limiting ring is slidably connected to the inner wall of the toothed plate.

[0010] Furthermore, the spring assembly includes a limiting rod, which is fixedly connected to the front and rear ends of the left side of the fixed base. The outer left end of the limiting rod is slidably connected to the inner wall of the slide. A second spring is sleeved on the outer middle end of the limiting rod. One end of the second spring is fixedly connected to the left side of the fixed base, and the other end of the second spring is fixedly connected to the right side of the slide.

[0011] Furthermore, the mounting blocks are fixedly connected to the right side of blade one and the left side of blade two, respectively, and the outer wall of the mounting blocks is detachably connected to the inner wall of the rotating shaft.

[0012] Furthermore, the positioning block is fixedly connected to the front and rear ends of the right side of the slide rod, and the outer wall of the positioning block is detachably connected to the inner wall of the positioning plate.

[0013] Furthermore, the outer wall of the toothed plate is slidably connected to the inner wall of the right end of the window frame.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the angle adjustment and fixing are achieved by using a linkage structure of slide bar, toothed plate, gear and rotating shaft to achieve precise multi-angle adjustment, and by cooperating with spring and positioning plate to ensure stable fixing after adjustment and avoid angle deviation during operation.

[0016] In this invention, the ease of maintenance is achieved through the detachable connection between the mounting block and the rotating shaft, combined with the sliding design of blade one and blade two. During maintenance, only the size of the blade needs to be reduced by sliding it to remove the mounting block for replacement, without having to disassemble the entire louver, which greatly reduces the difficulty and time cost of maintenance.

[0025] 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.

[0026] Reference Figures 1-3This utility model provides an embodiment of a sliding elevator car louver ventilation structure, including a window frame 1. Multiple rotating shafts 2 are rotatably connected to the left and right sides of the inner wall of the window frame 1. A gear 6 is fixedly connected to the right side of the right rotating shaft 2. A sliding groove 8 is opened at the middle of the right side of the outer wall of the window frame 1. A sliding rod 9 is slidably connected to the inner wall of the sliding groove 8. A toothed plate 7 is connected to the left end of the sliding rod 9 through a reset assembly. The rear side of the toothed plate 7 is meshed with the gear 6. A positioning plate 10 is fixedly connected to the right side of the outer wall of the window frame 1. The positioning plate 10 is connected to the sliding rod 9 through a positioning block 11. The inner walls of the left and right rotating shafts 2 are respectively connected to blade 2 5 and blade 4 through mounting blocks 3. The left inner wall of blade 4 is slidably connected to the right end of the outer wall of blade 2 5. A fixed seat 14 is fixedly connected to the left top side of blade 1 4. A sliding seat 15 is fixedly connected to the top side of blade 2 5. The sliding seat 15 is connected to the fixed seat 14 through a spring assembly.

[0027] Specifically, the detachable installation of blade 1 4 and blade 2 5 is achieved through the mounting blocks 3 at both ends. When maintenance or replacement is required, simply slide blade 1 4 and blade 2 5 in similar directions to reduce the lateral dimension, and pull the mounting block 3 out of the rotating shaft 2 to complete the disassembly. Utilizing the variable size characteristic of the sliding blades, the louvers can be maintained without disassembly, overcoming the operational limitations of the confined space of the elevator. It eliminates the need to completely remove the louvers, effectively solving the problems of the existing structure requiring the removal of many screws for cleaning and replacement, which is time-consuming and inconvenient due to the need to remove the car's decorative panels. Blade 1 4 and blade 2 5 are connected by a spring assembly. During installation, after the blades are loosened, the elastic force of spring 2 17 pushes the slide 15 to separate from the fixed seat 14, allowing the mounting block 3 to be firmly inserted. Within the rotating shaft 2, to ensure reliable connection, spring 17 ensures automatic tensioning of the blades after installation, eliminating gap wobbling noise from traditional hinge structures. The sliding rod 9 drives the gear plate 7 to mesh with the gear 6, thereby driving the rotating shaft 2 to rotate and adjust the angles of blade 4 and blade 5, achieving precise control of ventilation volume. The spring 13 in the reset assembly, when the sliding rod 9 is released after angle adjustment, pushes the sliding rod 9 to the right through the limit ring 12, causing the positioning block 11 to engage in the positioning groove of the positioning plate 10, forming a multi-angle stable fixation, avoiding angle deviation during operation. At the same time, the combination of high-precision gear plate transmission (industrial equipment grade) and spring positioning mechanism solves the miniaturization and anti-loosening problem in elevator vibration scenarios.

[0028] Reference Figures 4-6The reset assembly includes a limiting ring 12, which is fixedly connected to the outer left end of the slide rod 9. A spring 13 is fixedly connected to the left side of the limiting ring 12, and the other end of the spring 13 is fixedly connected to the inner wall of the toothed plate 7. The outer side of the limiting ring 12 is slidably connected to the inner wall of the toothed plate 7. The spring assembly includes a limiting rod 16, which is fixedly connected to the front and rear ends of the left side of the fixed base 14. The outer left end of the limiting rod 16 is slidably connected to the inner wall of the slide base 15, and a sleeve is provided at the middle outer end of the limiting rod 16. Spring 17, one end of which is fixedly connected to the left side of the fixed seat 14, and the other end of which is fixedly connected to the right side of the slide 15; mounting block 3 is fixedly connected to the right side of blade 4 and the left side of blade 5 respectively, and the outer wall of mounting block 3 is detachably connected to the inner wall of rotating shaft 2; positioning block 11 is fixedly connected to the front and rear ends of the right side of slide rod 9, and the outer wall of positioning block 11 is detachably connected to the inner wall of positioning plate 10; the outer wall of toothed plate 7 is slidably connected to the inner wall of the right end of window frame 1;

[0029] Specifically, the sliding connection structure between blade 4 and blade 5, combined with the elastic reset of the spring assembly, can automatically align the mounting block 3 and the rotating shaft 2 during installation, improving assembly efficiency while ensuring synchronization and stability during blade angle adjustment. Its working principle is as follows: During installation, first slide blade 4 and blade 5 in a similar direction so that the mounting block 3 is aligned with the rotating shaft 2 and inserted. Then, release the blades, and spring 17 extends to push the slide block 15 away from the fixed seat 14, causing blades 4 and 5 to slide in opposite directions until the mounting block 3 is completely inserted into the inner wall of the rotating shaft 2. When adjusting the angle, push the slide rod 9 up and down. The slide rod 9 drives the toothed plate 7 to slide along the inner wall of the right end of the window frame 1 through the reset component. The toothed plate 7 meshes with the gear 6 and rotates. The gear 6 drives the right end rotating shaft 2 to rotate. At the same time, the left end blade 4 rotates synchronously through the rotating shaft 2 to achieve blade angle adjustment. After adjustment, release the slide rod 9. Spring 13 extends to push the limit ring 12 and slide rod 9 to the right, so that the positioning block 11 on the right side of the slide rod 9 is inserted into the positioning groove of the positioning plate 10, completing the angle fixation. This ensures that the louver remains stable under different ventilation requirements. Moreover, during maintenance, the mounting block 3 can be quickly removed by sliding the blades, greatly reducing maintenance difficulty and cost.

[0030] Working principle: During installation, slide blade 4 and blade 5 in a similar direction to reduce their lateral size. Then, align the mounting block 3 with the rotating shaft 2 and insert it. Release the blade, and spring 17 pushes the slide block 15 away from the fixed seat 14, causing the two blades to slide in opposite directions until the mounting block 3 is fully engaged and fixed inside the rotating shaft 2. The mounting block 3 is square. During angle adjustment, manually slide the slide rod 9 up and down. The slide rod 9 drives the toothed plate 7 to slide along the inner wall of the right end of the window frame 1. The toothed plate 7 meshes with the gear 6, driving the right-end rotating shaft 2 to rotate, which in turn links the left-end rotating shaft 2 and blade 4 to achieve synchronous adjustment of the blade angle. After the angle adjustment is completed, release the slide rod 9. Spring 13 extends and pushes the slide rod 9 to the right through the limiting ring 12, causing the positioning block 11 to engage in the positioning groove of the positioning plate 10, thus firmly fixing the blade angle. During disassembly and maintenance, slide blade 4 and blade 5 in similar directions to disengage mounting block 3 from shaft 2, which will allow for quick disassembly and easy cleaning or replacement.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
