Description
Technical Field
[0001] The utility model relates to the technical field of elevator floor door sills, in particular to an elevator floor door sill reconstruction structure. Background Art
[0002] The elevator sill is a grooved metal pedal for entering and exiting the elevator car or floor door entrance. Elevator sills are divided into car sills and floor door sills. The floor door sill is the sill located at the floor door entrance.
[0003] For example, Chinese patent publication number CN219362940U discloses a landing door sill structure for an elevator, comprising a sill body and a fixed bracket, wherein a mounting groove is defined within the fixed bracket, and a sill body is slidably disposed within the mounting groove, wherein two sill bodies are located at opposite ends of the fixed bracket, and wherein a sliding groove is defined within the sill body.
[0004] In the above-mentioned prior art, the two sill bodies can move left and right along the fixed bracket, which is convenient for adjusting the usable length of the entire landing door sill. The slider moves left and right along the sliding groove, which can drive the elevator landing door to move and prevent the stop block and the landing door from deflecting during the movement.
[0005] However, as the elevator door opens and closes, dust easily enters the guide groove of the sill body, which greatly reduces the sliding stability of the guide block. Moreover, after a certain amount of dust accumulates, the dust in the sill groove is sensed by the sensor on the elevator opening and closing door, making it impossible to close. The guide groove of the sill body is narrow and requires the use of specific tools to clean it, which affects the normal use of the elevator door. Utility Model Content
[0006] The purpose of the utility model is to provide an elevator floor door sill modification structure, which can clean the internal dust as the elevator door opens and closes, avoiding the situation where the dust in the sill groove is sensed by the sensor on the elevator opening and closing door and cannot be closed after a certain amount of dust accumulates, and at the same time, improves the sliding stability of the guide block.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a structure for modifying the sill of an elevator floor door, comprising a sill body and symmetrically arranged sliders, a material box fixedly installed at the bottom of the sill body, a cloth bag penetrating one side of the material box, guide blocks integrally formed at the bottom of two groups of sliders, wedge-shaped scrapers fixedly installed on adjacent surfaces of the two groups of guide blocks, a felt plate fixedly installed at the edge of one side of the bottom of the wedge scraper, a guide groove provided at the top of the sill body, and an overflow groove provided through the middle of the guide groove.
[0008] Preferably, the guide groove extends into the inner cavity of the material box, and an inclined groove is provided at the connection between the material box and the cloth bag.
[0009] Preferably, rollers are rotatably mounted on the middle portions of the two groups of guide blocks away from each other, and the rollers are in contact with the bottom of the inner wall of the guide groove.
[0010] Preferably, the two groups of sliding blocks are I-shaped structures, and the two groups of sliding blocks slide on both sides of the top opening of the guide groove respectively.
[0011] Preferably, the two groups of wedge-shaped scrapers slide respectively in the inner wall of the guide groove, and the felt on the side of the felt plate contacts the bottom of the inner wall of the guide groove.
[0012] Preferably, adjacent surfaces of the two groups of wedge-shaped scrapers are respectively provided with oblique cuts.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] The guide block of the utility model is connected with the elevator landing door. When the elevator landing door and the guide block are opened and closed, the felt plates at the bottom edges of the adjacent surfaces of the wedge-shaped scrapers can slide synchronously in the guide grooves, and the oblique cuts on the adjacent surfaces of the two sets of wedge-shaped scrapers can block the accumulated dust and guide it forward to avoid overflowing from the top of the guide grooves, so that the accumulated dust in the guide grooves can be cleaned from both sides to the overflow groove in the middle, and after being received by the material box below, the dust is centrally guided into the bag. In this way, the elevator landing door sill guide groove can clean the internal dust as the elevator door opens and closes, and avoid the dust in the sill groove being sensed by the sensor on the elevator opening and closing door and unable to close after a certain amount of dust accumulates.
[0015] In the utility model, two groups of I-shaped sliding blocks are slidably engaged with the top opening of the guide groove, and the guide blocks and wedge-shaped scrapers on the adjacent surfaces of the two groups of sliding blocks guide and slide inside the guide groove, thereby preventing the sliding blocks from falling out of the guide groove, and the rollers on the outside of the guide blocks can make the sliding of the sliding blocks smoother.
