Description

Technical Field

[0001] This utility model relates to the field of elevator landing sill technology, and in particular to an elevator landing sill anti-foreign object jamming and cleaning mechanism. Background Technology

[0002] Injection molded parts are widely used in many industries such as automobiles, electronics, and home appliances due to their advantages of convenient molding and reasonable cost. However, their quality directly affects product performance and safety. Traditional manual inspection is not only inefficient but also susceptible to subjective factors, leading to insufficient accuracy. The widespread adoption of automated inspection equipment has created an urgent need for highly adaptable and accurate fixtures. Therefore, developing a reliable elevator landing sill anti-object jamming and cleaning mechanism has become a key link in improving production quality and efficiency. Announcement No. CN219362940U discloses an elevator landing sill structure, which includes a sill body and: a fixed bracket with an internal mounting groove, in which the sill body is slidably disposed, with two sill bodies located at both ends of the fixed bracket; a sliding groove inside the sill body; a locking bolt on the outside of the fixed bracket, one end of which penetrates the fixed bracket and contacts the sill body; and a slider with a roller slidably disposed inside the sliding groove, the roller contacting the inner wall of the sliding groove. However, the device is cleaned manually, which is not only labor-intensive but also difficult to guarantee the cleaning frequency. Often, it is only dealt with after a large amount of foreign objects have accumulated or even caused jamming, which affects the safety and smoothness of elevator operation and needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background section.

[0004] This utility model adopts the following technical solution: an elevator landing sill anti-foreign object jamming and cleaning mechanism, including a sill, a slider is slidably connected inside the sill, a rack A is fixedly installed inside the slider, a gear A meshes on the surface of the rack A, a rack B meshes on the surface of the gear A, a movable frame is fixedly installed at the bottom of the rack B, a storage cover is fixedly installed on one side of the movable frame, an installation plate is fixedly installed at the bottom of the storage cover, a spring A is installed on the surface of the installation plate, a clamping plate is fixedly installed at one end of the spring A, a scraper frame is slidably connected inside the slider, a cleaning scraper is fixedly installed inside the scraper frame, a storage box is fixedly installed at the bottom of the sill, and a discharge plate is slidably connected inside the storage box.

[0005] Preferably, a maintenance cover is slidably connected inside the sill, and the surface of the scraper frame is slidably connected to the inside of the slider. This allows the maintenance cover to be flexibly opened, facilitating the operator's inspection and maintenance of the components inside the sill.

[0006] Preferably, the surface of the storage cover is slidably connected to the inner surface of the sill, and the spring A passes through one side of the storage box. This ensures that the clamping plate can move flexibly under the action of spring A during the closing and opening of the elevator door, effectively clamping foreign objects and reducing the space occupied by them.

[0007] Preferably, one side of gear A is rotatably connected to the inner surface of the sill, and the surface of the mounting plate is slidably connected to the interior of the sill. This ensures the accuracy and stability of the transmission and reduces power transmission loss caused by gear wobble.

[0008] Preferably, the slider is internally rotatably connected to a gear B, a gear C is fixedly mounted on one side of the gear B, a rack C meshes with the surface of the gear C, a spring B is fixedly mounted on one end of the rack C, and a rack D meshes with the surface of the gear B. Here, the scraper frame and cleaning scraper are moved, compensating for scraper wear, increasing scraper life, and ensuring effective contact with the inside of the sill at all times, maintaining a stable cleaning effect.

[0009] Preferably, the surface of the rack C is slidably connected to the interior of the slider, and one side of the rack D is fixedly connected to the surface of the scraper frame. This allows for precise movement of the cleaning scraper, ensuring timely downward compensation when the scraper wears down.

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

[0011] 1. This utility model includes components such as a sill, slider, rack A, gear A, rack B, moving frame, cleaning scraper, and storage box. Each time the elevator door closes, the slider inside the sill moves. The slider drives gear A via rack A, which in turn drives the moving frame via rack B. This causes the cleaning scraper to clean the inside of the sill, scraping foreign objects into the storage box, thus achieving automatic cleaning with each closing. Simultaneously, the mounting plate moves with the moving frame, and spring A on its surface causes the clamping plate to move to both sides and then return to its original position, clamping and compressing foreign objects inside the storage box, reducing the space occupied by foreign objects and thus reducing the number of times the storage box needs to be manually cleaned. This achieves automatic cleaning with each closing, reducing the need for manual cleaning.

[0012] 2. In this utility model, by setting gear B, gear C, rack C, spring B and rack D, when the cleaning scraper wears, the slider drives the spring B to release force and push the rack C to move, which drives the meshing gear C to rotate. Gear B rotates synchronously, driving the meshing rack D to move, causing the scraper frame and cleaning scraper to move downward, compensating for wear, ensuring cleaning effect, extending service life and reducing maintenance costs.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] 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.

[0023] Example 1

[0024] Please see Figure 1-4An elevator landing door sill anti-object jamming and cleaning mechanism includes a sill 1, with a slider 2 slidably connected inside the sill 1. The slider 2 moves as the elevator door moves. The internal sliding connection facilitates smooth movement of the slider 2 within the sill 1, enabling power transmission. A rack A3 is fixedly installed inside the slider 2 to ensure synchronous movement between the rack A3 and the slider 2. A gear A4 meshes with the surface of the rack A3, enabling force transmission and direction conversion through gear meshing. A rack B5 meshes with the surface of the gear A4, converting the rotational motion of the gear A4 into the linear motion of the rack B5. A movable frame 6 is fixedly installed at the bottom of the rack B5, allowing the rack B5 to drive the movable frame 6 to move synchronously. A storage cover 7 is fixedly installed on one side of the movable frame 6, enabling the storage cover 7 to open and close synchronously with the movable frame 6. An installation plate 8 is fixedly installed at the bottom of the storage cover 7, providing a mounting base for a spring A9. A spring A9 is installed on the surface of the installation plate 8, using the spring force to reset and clamp a clamping plate 10. A clamping plate 10 is fixedly installed at one end of the spring A9, which can hold the spring in place. The foreign objects inside the storage box 13 are clamped and compressed. A scraper frame 11 is slidably connected inside the slider 2, allowing the scraper frame 11 to move relative to the slider 2 to compensate for wear. A cleaning scraper 12 is fixedly installed inside the scraper frame 11 to clean the inside of the sill 1. A storage box 13 is fixedly installed at the bottom of the sill 1 to collect the cleaned foreign objects. A discharge plate 14 is slidably connected inside the storage box 13 for easy removal of foreign objects. A maintenance cover 15 is slidably connected inside the sill 1 for easy opening and maintenance. For maintenance and repair, the surface of the scraper frame 11 is slidably connected to the inside of the slider 2 to ensure smooth movement of the scraper frame 11. The surface of the storage cover 7 is slidably connected to the inner surface of the sill 1 to ensure stable opening and closing of the storage cover 7. The spring A9 passes through one side of the storage box 13, so that the spring A9 can drive the clamp 10 to act on foreign objects in the storage box 13. One side of the gear A4 is rotatably connected to the inner surface of the sill 1 to ensure stable rotation of the gear A4. The surface of the mounting plate 8 is slidably connected to the inside of the sill 1 to ensure stable movement of the mounting plate 8.

[0025] Example 2

[0026] Please see Figure 5 The slider 2 is internally connected to a gear B16, which ensures stable rotation of the gear B16. A gear C17 is fixedly installed on one side of the gear B16, allowing the gears B16 and C17 to rotate synchronously. A rack C18 meshes with the surface of the gear C17, converting the rotational motion of the gear C17 into the linear motion of the rack C18. A spring B19 is fixedly installed at one end of the rack C18, using the spring force to push the rack C18 to move. A rack D20 meshes with the surface of the gear B16, converting the rotational motion of the gear B16 into the linear motion of the rack D20. The surface of the rack C18 is slidably connected to the inside of the slider 2, ensuring smooth movement of the rack C18. One side of the rack D20 is fixedly connected to the surface of the scraper frame 11, allowing the rack D20 to drive the scraper frame 11 to move to compensate for wear.

[0027] Working principle: When the elevator door closes, it moves the slider 2 inside the sill 1. During the movement of slider 2, the rack A3 inside moves synchronously. Since rack A3 meshes with gear A4, the movement of rack A3 will drive gear A4 to rotate. Gear A4 then meshes with rack B5, driving rack B5 to move. Rack B5 then drives the bottom moving frame 6 to move, and the storage cover 7 on one side of the moving frame 6 moves together, opening the storage cover 7. At the same time, the mounting plate 8 at the bottom of the storage cover 7 moves with the storage cover 7, and the spring A9 and clamping plate 10 on the surface of the mounting plate 8 also move accordingly. With the cooperation of the storage box 13, spring A9 drives clamping plate 10 to move to both sides, and the scraper frame 11 slidably connected inside slider 2 will move when slider 2 moves. As the scraper moves downward, the cleaning scraper 12 inside the scraper frame 11 cleans the inside of the sill 1, pushing the scraped foreign objects into the storage box 13. During this process, the spring B19 will begin to contract under the pressure from both sides, and the racks C18 on both sides will be stressed. When the cleaning scraper 12 wears out due to long-term use, the contracted spring B19 will release its elasticity, pushing the racks C18 on both sides to move. The racks C18 mesh with the gear C17, driving the gear C17 to rotate. The gear B16 on one side of the gear C17 rotates synchronously. The gear B16 meshes with the rack D20, thereby driving the rack D20 to move. The rack D20 then drives the scraper frame 11 and the cleaning scraper 12 to move downward, thereby compensating for the wear of the cleaning scraper 12 and effectively increasing the service life of the cleaning scraper 12. When the elevator door opens, spring B19 continues to release its elastic force, still exerting force to both sides. This pushes rack C18, drives gears C17 and B16 to rotate, and drives rack D20 to move, ensuring that the scraper frame 11 and cleaning scraper 12 remain in a downward movement without moving upward. This ensures that the cleaning scraper 12 always maintains effective contact with the inside of the sill 1, guaranteeing continuous cleaning effectiveness. Simultaneously, slider 2 moves in the opposite direction as the elevator door opens, and its internal rack A3 moves in the opposite direction, driving gear A4 to rotate in the opposite direction, which in turn drives rack B5 to move in the opposite direction. Rack B5 drives the moving frame 6 and storage cover 7 to move in the opposite direction, closing the storage cover 7. The mounting plate 8, spring A9, and clamping plate 10 at the bottom of the storage cover 7 also move in the opposite direction. At this time, under the force of spring A9, clamping plate 10 clamps and compresses foreign objects inside the storage box 13, reducing the space occupied by foreign objects and improving the storage efficiency of the storage box 13.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present 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 the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
