However, this solution lacks the function of automatic cleaning and dust collection of the sill body. Utility Model Content

[0004] The purpose of this invention is to provide an elevator sill with a self-cleaning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elevator sill with self-cleaning function, comprising a sill body, an elevator door slidably disposed within the sill body, a slot being provided inside the elevator door, a storage groove being provided inside the slot, a dustproof component for preventing dust from the sill body being installed in the storage groove, a mounting groove being provided on the sill body, an installation frame being installed in the mounting groove, and a dust collection component being provided in the installation frame.

[0006] Furthermore, the dustproof component includes a take-up roller rotatably mounted in the storage groove, and a torsion spring is provided at the connection between the take-up roller and the storage groove. A soft strip is wound on the take-up roller, and a groove is provided on the soft strip. The end of the soft strip away from the take-up roller is fixedly mounted on the mounting frame.

[0007] Furthermore, the collection component includes a dust collection box placed inside the mounting frame. The dust collection box has symmetrical slots at both ends, and an extension box is rotatably mounted on the slot. The two extension boxes are connected by a first spring, and a shielding mechanism is provided below the extension box to cooperate with it.

[0008] Furthermore, the shielding mechanism includes a baffle disposed below and in contact with the expansion box, the bottom end of the baffle being provided with a plurality of second springs, and the end of the second spring away from the baffle being connected to the bottom wall of the dust collection box.

[0009] Furthermore, the ash collection box is equipped with a limiting plate.

[0010] Furthermore, the inner wall of the groove is provided with a scraper that cooperates with the soft belt.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the self-cleaning elevator sill is reasonable and has the following advantages:

[0012] (1) The elevator sill design significantly improves the dust prevention and cleaning effect through dustproof components and automatic cleaning mechanism. The soft belt is spread out when the elevator door moves, effectively blocking dust and other impurities from entering the sill groove. When the elevator door moves relative to the other side, the torsion spring drives the winding roller to reverse and retract the soft belt. At the same time, the scraper on the inner wall of the groove cleans the soft belt, ensuring that the dust and impurities on the surface of the soft belt are removed. This process not only reduces the chance of dust entering the sill groove, but also ensures that the soft belt is always clean through the automatic cleaning mechanism, thereby extending the service life of the soft belt and reducing the maintenance frequency. The collected dust will fall into the dust collection box along the winding of the soft belt, which is convenient for subsequent centralized cleaning, further improving the cleaning efficiency and convenience. This design not only improves the dust prevention performance of the elevator sill, but also reduces manual intervention through automated cleaning, improving the overall cleaning effect and the reliability of equipment operation.

[0013] (2) The dust collection component of the elevator sill, through the cooperation of the dust collection box and the expansion box, significantly enhances the dust collection capacity and improves the convenience of maintenance. This design allows the dust collection box to enter smoothly when inserted into the mounting slot, and the expansion box pops out under the action of the first spring, thereby expanding the collection space. At the same time, the cooperation of the baffle and the second spring ensures that the expansion box will not leak dust when it rotates. The slot limits the expansion box to prevent it from flipping out, while the limiting plate prevents the dust collection box from falling off the mounting frame. This design not only improves the efficiency of dust collection, but also ensures the stability and reliability of the dust collection box through a clever mechanical structure. Workers can easily pull out the dust collection box by prying up the limiting plate to clean the dust and impurities inside. This convenient maintenance design reduces maintenance time and labor intensity and improves the maintainability of the equipment. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-7 The present invention provides a technical solution as follows:

[0024] Example 1:

[0025] An elevator sill with self-cleaning function includes a sill body 100, an elevator door 101 slidably disposed within the sill body 100, a slot 102 formed within the elevator door 101, a storage slot 103 formed within the slot 102, a dustproof component for preventing dust from the sill body 100 installed within the storage slot 103, a mounting slot 200 formed on the sill body 100, a mounting frame 201 installed within the mounting slot 200, and a dust collection component disposed within the mounting frame 201.

[0026] The dustproof component includes a take-up roller 104 rotatably installed in the storage groove 103, and a torsion spring is provided at the connection between the take-up roller 104 and the storage groove 103. A soft strip 105 is wound on the take-up roller 104, and a groove is provided on the soft strip 105. The end of the soft strip 105 away from the take-up roller 104 is fixedly installed on the mounting frame 201.

[0027] The collection component includes a dust collection box 202 placed inside the mounting frame 201. The dust collection box 202 has symmetrical slots 204 at both ends. An expansion box 205 is rotatably mounted on the slot 204. The two expansion boxes 205 are connected by a first spring 206. A shielding mechanism is provided below the expansion box 205 to cooperate with it.

[0028] The shielding mechanism includes a baffle 207 disposed below and in contact with the expansion box 205. The bottom end of the baffle 207 is provided with a plurality of second springs 208, and the end of the second spring 208 away from the baffle 207 is connected to the bottom wall of the dust collection box 202.

[0029] The ash collection box 202 is provided with a limiting plate 203.

[0030] The inner wall of the slot 102 is provided with a scraper 106 that cooperates with the soft belt 105.

[0031] Working principle: In use, first pinch the two expansion boxes 205, and under the action of the first spring 206, they move relative to each other, so that the dust collection box 202 can be inserted into the placement slot 200 along the mounting frame 201. After insertion, under the action of the first spring 206, the two expansion boxes 205 are popped out, thereby expanding the collection space and preventing the dust collection box 202 from being easily removed. The baffle 207 is always in contact with the expansion box 205 under the action of the second spring 208, which can ensure that the dust is leaked while the expansion box 205 is rotating. At the same time, the slot 204 can limit the expansion box 205 to prevent it from flipping out. The limiting plate 203 installed on the dust collection box 202 can limit it to prevent it from falling off the mounting frame 201.

[0032] Secondly, since one end of the soft belt 105 is fixed to the mounting frame 201, when the elevator door 101 moves in opposite directions, the soft belt 105 spreads out along the sill body 100, which can prevent dust and other impurities from entering. The groove on the soft belt 105 facilitates the collection of dust and other impurities, and also facilitates subsequent cleaning. Since the winding roller 104 is provided with a torsion spring at the connection between it and the storage groove 103, when the elevator door 101 moves in opposite directions, the torsion spring drives the winding roller 104 to reverse and retract the soft belt 105. The scraper 106 installed on the inner wall of the groove 102 will clean the soft belt 105. The dust that falls on the soft belt 105 will fall into the dust collection box 202 along the winding of the soft belt 105 for subsequent cleaning.

[0033] Finally, the staff can pull out the dust collection box 202 by prying up the limit plate 203, thereby cleaning the dust and impurities in the dust collection box 202.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
