Technical Field
[0001] This utility model relates to the field of elevator sill technology, specifically a sill component for elevator doors. Background Technology
[0002] An elevator sill is a grooved metal step used for entering and exiting an elevator car or landing door. It is a horizontal metal component that is flush with the ground. The grooves on the elevator sill are used to assist in the opening and closing of the elevator door or landing door. When the elevator door or landing door is opened, debris can easily fall into the grooves, which can affect the normal opening and closing of the elevator door or landing door.
[0003] Existing patent CN215626082U discloses an elevator sill that is easy to clean. The elevator sill body is provided with a sliding groove that connects to a cleaning groove. The cleaning groove can increase the cleaning space and facilitate cleaning. The side of the sliding groove away from the sliding groove transitions to the upper surface of the elevator sill body in an arc shape, which allows the garbage to be swept out more easily from the transition surface. The mounting block fills the sliding groove and is detachably fitted to the elevator sill body. The upper surface of the mounting block is flush with the upper surface of the elevator sill body. This not only satisfies the need for convenient and efficient cleaning of the garbage in the sliding groove, but also does not affect the performance of the sliding fit between the elevator sill and the elevator door.
[0004] While the aforementioned patents facilitate the cleaning of debris in the chute, they do not fundamentally solve the problem. When the elevator door or landing door is opened, debris can still easily fall into the chute, affecting the normal opening or closing of the elevator door or landing door. Therefore, a sill assembly for elevator doors is proposed. Utility Model Content
[0005] The purpose of this utility model is to solve the technical problem that when elevator doors or landing doors are opened, debris easily falls into the slide rails, which affects the normal opening or closing of the elevator doors or landing doors. This utility model provides a sill assembly for elevator doors.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A sill assembly for an elevator door includes a sill body with a sliding groove, two receiving slots and an embedding slot both communicating with the sliding groove, a baffle plate slidably disposed within the receiving slot, and inwardly contracting guide slopes on opposite sides of the baffle plate. A reset member and a locking member are disposed between the baffle plate and the sill body. The reset member drives the baffle plate to slide in one direction, and the locking member locks or unlocks the baffle plate. The assembly also includes a collection box having a connected flat surface and a stepped surface. The flat surface slides into the embedding slot, and the stepped surface abuts against the sliding groove. The collection box has multiple drainage holes.
[0008] Furthermore, the locking component includes a locking screw disposed on the baffle plate, and the sill body has a notch communicating with the storage groove. The locking screw slides into the notch, and a locking nut that abuts and overlaps with the sill body is threaded onto the locking screw.
[0009] Furthermore, two sealing gaskets are provided on the sill body.
[0010] Furthermore, buffer strips are provided on opposite sides of both of the shields.
[0011] Furthermore, the shield plate is provided with a groove, and multiple rollers are rotatably arranged in the groove.
[0012] Furthermore, the opening of the collection box is constructed in an outwardly expanding cone shape.
[0013] Furthermore, the reset component includes a reset spring disposed between the baffle plate and the sill body.
[0014] Furthermore, the reset component includes a first magnet disposed on the sill body, and a second magnet and a third magnet are disposed on the shield plate. The first magnet and the second magnet are magnetically repelled, while the two third magnets are magnetically attracted.
[0015] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, when the elevator door or landing door is opened, the two baffles together block the slide rail, reducing the probability of debris falling into the slide rail. Even if debris falls into the slide rail, the collection box collects the debris, preventing impurities from remaining in the slide rail, so as to avoid debris affecting the normal opening or closing of the elevator door or landing door. Therefore, it is more practical. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0027] This embodiment provides a sill assembly for elevator doors, mainly to solve the technical problem that debris easily falls into the track when the elevator door or landing door is opened, and this debris affects the normal opening or closing of the elevator door or landing door. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-9 Please provide a detailed explanation: Example
[0028] A sill assembly for an elevator door includes a sill body 1, which is horizontal. A sliding groove 2 is constructed on the sill body 1, distributed along its length. Two receiving slots 3 and an embedding slot 4, both communicating with the sliding grooves 2, are also constructed on the sill body 1. The two receiving slots 3 are respectively connected to both sides of the sliding groove 2, and the embedding slot 4 is connected to the bottom of the sliding groove 2. A baffle 5 is slidably disposed within the receiving slots 3. The baffle 5 is horizontal and slides along the horizontal direction. During sliding, the baffle 5 has relatively distributed initial and extreme positions. In the initial position, the baffle 5 is partially located within the sliding groove 2. At the extreme position, the shield 5 retracts into the storage groove 3. The opposite sides of the shield 5 are constructed with inwardly contracting guide slopes. A reset member and a locking member are provided between the shield 5 and the sill body 1. The reset member drives the shield 5 to slide in one direction. The one-way sliding here refers to driving the shield 5 to slide from the extreme position to the initial position. The locking member locks or unlocks the shield 5. It also includes a collection box 6. The collection box 6 has a connected flat surface and a stepped surface. The flat surface slides into the embedded groove 4, and the stepped surface abuts against the sliding groove 2. The collection box 6 is constructed with multiple drain holes 7, and the multiple drain holes 7 are all located on the inner bottom surface of the collection box 6.
[0029] In the initial state, when the elevator door or landing door is open, the two baffles 5 are close to each other and both are in their initial positions. Together, the two baffles 5 block the slide rail 2, reducing the probability of debris falling into it. When the elevator door or landing door closes, it first contacts the guide ramp. Through the transition effect of the guide ramp, the two baffles 5 are forced to slide together to their limit positions. The two baffles 5 then move away from each other and release their blockage of the slide rail 2. Afterward, the elevator door or landing door contacts the baffles 5. Conversely, when the elevator door or landing door opens, two reset components drive the two baffles 5 to slide unidirectionally. Both baffles 5 slide from their limit positions to their initial positions, together again blocking the slide rail 2, reducing the probability of debris falling into it. When the elevator door or landing door is not fully open, if debris falls into the slide rail 2, it is immediately blocked by the guide ramp. The collection box 6 collects debris to prevent impurities from remaining in the chute 2, thus avoiding any obstruction to the normal opening or closing of the elevator door or landing door. Multiple drain holes 7 allow liquid to drain out. When the collection box 6 needs to be disassembled, the elevator door or landing door opens, causing both baffles 5 to slide to their limit positions. Two locking devices then lock the two baffles 5, causing the collection box 6 to move upwards until it exits the chute 2, with its flat surface away from the embedded groove 4 and its stepped surface away from the chute 2. The debris in the collection box 6 can then be emptied. Conversely, the collection box 6 enters the chute 2, allowing its flat surface to slide into the embedded groove 4 and its stepped surface to abut against the chute 2. Two locking devices then unlock the two baffles 5, and two reset devices drive the two baffles 5 to slide unidirectionally from their limit positions back to their initial positions.
[0030] In summary, when this application is in use, when the elevator door or landing door is opened, the two baffles 5 together block the slide 2, reducing the probability of debris falling into the slide 2. Even if debris falls into the slide 2, the collection box 6 collects the debris, preventing impurities from remaining in the slide 2, thus avoiding the debris from affecting the normal opening or closing of the elevator door or landing door. Therefore, it is more practical.
[0031] like Figure 3 As shown, in this embodiment, the locking component includes a locking screw 8 disposed on the baffle plate 5. The locking screw 8 is vertical and fixed on the baffle plate 5. The sill body 1 is provided with a notch 9 that communicates with the storage groove 3. The locking screw 8 is slidably engaged with the notch 9. The locking screw 8 is slidably engaged with the notch 9 in the horizontal direction. The locking screw 8 is threaded with a locking nut 10 that abuts against and overlaps with the sill body 1.
[0032] Referring to the above, in the initial state, the locking nut 10 is in the loose state. When the baffle 5 slides from the initial position to the limit position, it drives the locking screw 8 and the locking nut 10 to move together. The locking screw 8 is engaged with the notch 9. When the baffle 5 slides from the limit position to the initial position, the locking screw 8 disengages from the notch 9. In use, the locking nut 10 is tightened until it abuts against the sill body 1, and the baffle 5 cannot slide, thus locking the baffle 5. Conversely, the locking nut 10 is loosened away from the sill body 1 to unlock the baffle 5.
[0033] like Figure 1 As shown, in this embodiment, two sealing gaskets 11 are provided on the sill body 1. The sealing gaskets 11 are horizontal and fixed on the sill body 1. The sealing gaskets 11 are attached to the bottom of the elevator door or landing door.
[0034] Referring to the above, when using the device, the sealing gasket 11 can improve the sealing performance and further reduce the probability of impurities falling into the chute 2.
[0035] like Figure 3 As shown, in this embodiment, buffer strips 12 are provided on opposite sides of the two baffles 5. The buffer strips 12 are horizontal and fixed on the baffles 5.
[0036] Referring to the above, in the initial state, both shields 5 are in the initial position and the two buffer strips 12 are in contact and overlapping. When both shields 5 slide to their limit positions, the two buffer strips 12 move away from each other. When both shields 5 slide from their limit positions to their initial positions, the two buffer strips 12 work together to buffer each other and prevent collisions between the two shields 5.
[0037] like Figure 3As shown, in this embodiment, the baffle plate 5 is provided with a groove 13, and a plurality of rollers 14 are rotatably arranged in the groove 13. The plurality of rollers 14 are all vertical and arranged in an array.
[0038] Referring to the above, when the elevator door or landing door comes into contact with the baffle 5, the multiple rollers 14 can reduce friction, which not only makes the sliding of the baffle 5 smoother, but also reduces damage to the elevator door or landing door.
[0039] like Figure 4 As shown, in this embodiment, the opening of the collection box 6 is constructed in an outwardly expanding cone shape;
[0040] Referring to the above, during use, the outwardly expanding conical design allows debris to smoothly enter the collection box 6, preventing debris from remaining in the chute 2.
[0041] like Figure 6 As shown, in this embodiment, the reset component includes a reset spring 15 disposed between the baffle plate 5 and the sill body 1. The reset spring 15 is horizontal and its two ends are fixedly connected to the baffle plate 5 and the sill body 1, respectively.
[0042] Referring to the above, when the baffle 5 is in the initial position, the return spring 15 is in the natural state. When the baffle 5 slides to the limit position, the return spring 15 is compressed. When the elevator door or landing door is opened, the return spring 15 will return to the natural state due to compression. The baffle 5 will slide from the limit position to the initial position due to elastic potential energy. When the baffle 5 is unlocked by the locking member, the return spring 15 will return to the natural state due to compression. The baffle 5 will slide from the limit position to the initial position due to elastic potential energy, thereby achieving unidirectional sliding of the baffle 5. Example
[0043] Example 2 proposes another structure for the reset component based on Example 1;
[0044] like Figure 9 As shown, in this embodiment, the reset component includes a first magnet 16 disposed on the sill body 1. The first magnet 16 is fixed on the sill body 1. A second magnet 17 and a third magnet 18 are disposed on the baffle plate 5. The second magnet 17 and the third magnet 18 are respectively fixed on opposite sides of the baffle plate 5. The two third magnets 18 are respectively fixed on opposite sides of the two baffle plates 5. The first magnet 16 and the second magnet 17 repel each other magnetically, and the two third magnets 18 attract each other magnetically.
[0045] Referring to the above, when the shield 5 is in the initial position, the two third magnets 18 are in contact and magnetically attracted to each other, and the second magnet 17 is away from the first magnet 16. When the shield 5 slides to the limit position, it drives the second magnet 17 and the third magnet 18 to move together. The second magnet 17 moves closer to the first magnet 16, and the two third magnets 18 move away from each other. The first magnet 16 and the second magnet 17 repel each other magnetically. When the elevator door or landing door is opened, the magnetic repulsion between the first magnet 16 and the second magnet 17 drives the shield 5 to slide from the limit position to the initial position, driving the second magnet 17 and the third magnet 18 to move together. The second magnet 17 moves away from the first magnet 16, and the two third magnets 18 are in contact and magnetically attracted to each other. Through the magnetic attraction between the two third magnets 18, both shields 5 are ensured to slide to the initial position, so as to achieve unidirectional sliding of the shield 5.
[0046] The working process of this utility model is as follows: In the initial state, when the elevator door or landing door is open, the two baffles 5 are close to each other and both are in their initial positions. The two baffles 5 together block the slide 2, reducing the probability of debris falling into the slide 2. When the elevator door or landing door is closed, it will first contact and overlap with the guide slope. Through the transition effect of the guide slope, the two baffles 5 are forced to slide together to their limit positions. The two baffles 5 move away from each other and release the blockage of the slide 2. Then the elevator door or landing door contacts the baffles 5. Conversely, when the elevator door or landing door is opened, the two baffles 5 are driven to slide unidirectionally by two reset members. Both baffles 5 slide from their limit positions to their initial positions. The two baffles 5 together block the slide 2 again, reducing the probability of debris falling into the slide 2. When the elevator door or landing door is not fully open, if debris falls into the slide 2... Inside the trough 2, the collection box 6 collects debris to prevent impurities from remaining in the trough 2 and thus avoiding any obstruction to the normal opening or closing of the elevator door or landing door. Multiple drain holes 7 allow liquid to drain out. When the collection box 6 needs to be removed, the elevator door or landing door opens, causing both baffles 5 to slide to their limit positions. Two locking devices then lock the two baffles 5, causing the collection box 6 to move upwards until it exits the trough 2, with its flat surface away from the embedded groove 4 and its stepped surface away from the trough 2. The debris inside the collection box 6 can then be emptied. Conversely, the collection box 6 is moved back into the trough 2, allowing its flat surface to slide into the embedded groove 4 and its stepped surface to abut against the trough 2. The two locking devices then unlock the two baffles 5, and two reset devices drive the two baffles 5 to slide unidirectionally from their limit positions back to their initial positions.
[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
