Description

Technical Field

[0001] The utility model belongs to the technical field of elevator cleaning, and in particular relates to an elevator sill structure which is convenient to clean. Background Art

[0002] Elevators are essential transportation equipment in modern high-rise buildings. Elevator equipment includes elevator sills. The elevator sill is a grooved metal pedal for entering and exiting the elevator car or floor door. It is a metal horizontal component close to the ground. The surface of the elevator sill is provided with metal grooves, which are used to assist in guiding the opening and closing of the elevator car door and floor door.

[0003] At present, foreign objects are easily entered into the metal groove on the surface of the elevator sill. If it is not cleaned in time, it will cause abnormal noise when the elevator door is opened or closed. For example, Chinese utility model patent CN217708474U discloses an elevator sill that is easy to clean. A movable plate is placed inside the recess. When the elevator door is operating normally, the bottom of the movable plate is attached to the bottom of the recess. At the same time, when dust and stones fall into the recess, they will stay on the surface of the movable plate. When cleaning is needed, it is only necessary to pull the movable plate upward under uniform force through the connecting mechanism so that the movable plate is flush with the surface of the elevator sill, and the effect of quick cleaning can be achieved; when the connecting mechanism is pulled, the movable block is pulled by pulling the telescopic rod to pull the connecting block, so that the movable plate is flush with the elevator sill, and the telescopic rod can be used to clamp the side of the elevator sill to prevent the movable plate from sliding down. At this time, the cover plate is opened and the cleaning brush is taken out from the storage box to clean the dust and stones on the surface of the elevator sill and the movable plate, which effectively improves the convenience of cleaning. After cleaning, it is only necessary to restore each component to its original state so that the movable plate can be located inside the recess for normal use.

[0004] Although the above-mentioned prior art can achieve a quick cleaning effect by pulling the connecting mechanism to pull the movable plate upward so that the movable plate is flush with the surface of the elevator sill, if the impurities inside the metal groove are not cleaned in time, abnormal noise will be generated when the elevator door is opened and closed, which may cause the elevator door to fail to open and close normally.

[0030] like Figure 1 As shown, it is a schematic diagram of an elevator sill structure that is easy to clean according to a preferred embodiment of the utility model. The elevator sill structure that is easy to clean in this embodiment includes a sill assembly 100. A metal groove 101 is provided at the upper end of the sill assembly 100. A movable plate 200 is rotatably connected to the inner bottom of the metal groove 101. A collecting box 300 is detachably connected to one side of the sill assembly 100. In this embodiment, the movable plate 200 rotates to transport impurities to the interior of the collecting box 300 for storage. The collecting box 300 can be removed to remove the impurities inside.

[0031] like Figure 2 , Figure 3 as well as Figure 5 As shown, it is a schematic diagram of the sill assembly, movable plate and collection box structure in this embodiment. A mounting groove 102 for mounting the collection box 300 is provided on one side of the sill assembly 100, and a connecting groove 103 is provided on the inner top of the mounting groove 102. The collection box 300 is inserted into the connecting groove 103. An entry groove 104 is provided between the mounting groove 102 and the metal groove 101. The movable plate 200 rotates so that the movable plate 200 tilts toward the mounting groove 102 to pour impurities into the collection box 300. The outer wall of the collection box 300 is provided with a feed port 302. Impurities enter the collection box 300 from the inside of the feed port 302. The collection box 300 is then taken out from the inside of the connecting groove 103, and the impurities in the collection box 300 are poured out, thereby preventing impurities from accumulating in the metal groove 101 and affecting the opening and closing actions of the elevator door.

Under normal conditions, the movable plate 200 is in an inclined state, and the inclination direction of the movable plate 200 is the same as that of the entry groove 104. The setting of the movable plate 200 and the inclined surface makes it easier for impurities to enter the interior of the feed port 302.

[0033] like Figure 5 as well as Figure 6 As shown, it is a schematic diagram of the collection box and the cross-sectional structure of the collection box in this embodiment, the internal rotation of the feed port 302 is connected to a rotating door panel 301, the rotating door panel 301 rotates outward and rests on the inner bottom of the entry groove 104, and a plurality of traction ropes 303 passing through the collection box 300 are connected to the rotating door panel 301, and an inner groove 307 is provided at the upper end of the collection box 300, and a connecting plate 305 fixedly connected to each traction rope 303 is provided at the inner bottom of the inner groove 307, and a handle 306 is fixedly connected to the upper end of the connecting plate 305. When taking out the collection box 300, first use a tool to insert the handle 306 into the inside and tilt it upward, then hold the handle 306 and pull it upward, and close the rotating door panel 301 through the traction rope 303. After the rotating door panel 301 is closed, it can be removed from the connecting hole 306. The interior of the groove 103 can be pulled out, so that impurities can be easily cleaned, and the rotating door panel 301 can be closed during the upward movement of the collection box 300 to prevent impurities in the collection box 300 from falling outward. During installation, the rotating door panel 301 is closed by gravity, so that it can be easily inserted into the interior of the connecting groove 103. After placing it, the handle 306 is released and the traction rope 303 is spread outward by gravity to rest on the bottom of the entry groove 104. The inner groove 307 is set to make the height of the handle 306 lower than the upper end of the collection box 300, thereby preventing misoperation. In this embodiment, the inner wall of the feed port 302 is rotatably connected to the rotating rod 304, and the rotating rod 304 can reduce the friction when the traction rope 303 is pulled, thereby increasing the service life of the traction rope 303.

[0034] like Figure 4 As shown, it is a schematic diagram of the expansion airbag structure in this embodiment, an expansion airbag 202 is arranged between the bottom of the expansion airbag 202 close to the higher inclined end and the bottom of the metal groove 101, and a micro compressor 203 connected to the expansion airbag 202 is installed on the outer wall of the mounting bracket 201 on one side. The micro compressor 203 makes the expansion airbag 202 expand so that the inclination angle of the mounting bracket 201 is larger, thereby making it easier to transport impurities to the interior of the collection box 300.
