Description

Technical Field

[0001] The utility model relates to the field of elevator components, in particular to an aluminum-iron composite anti-slip sill. Background Art

[0002] The sill is the pedal part of the elevator floor door, which guides and protects the movement of the elevator floor door. It is one of the important components of elevator installation. Traditional sills are generally made of aluminum alloy, but with the development of the times and the intensification of competition, in order to reduce the production cost of sills while improving the overall strength, aluminum-iron composite sills have gradually become the mainstream in actual production. However, the existing aluminum-iron composite sills are generally composed of two parts: a U-shaped sill bracket and an aluminum alloy sill body, which are then connected together by bolts. However, when this type of sill is assembled, the top of the sill bracket is generally directly against the back of the sill body. In this way, during actual use, there will be a lateral force during the movement of the elevator floor door, which drives the back of the sill body and the sill bracket to move relative to each other, resulting in a lot of noise. In addition, the door slot structure of the sill is generally a straight slot, so there is a risk of falling off during the movement of the floor door. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a sill assembly, which can improve the stability and safety of the movement of the landing door and reduce the generation of noise.

[0005] In a preferred embodiment of the present invention, a retaining bar is provided below the inner pedal, and the distance between the retaining bar and the inner support plate is greater than or equal to the width of the bolted connection plate. The width of the inner support foot is no greater than the distance from the retaining bar to the inner edge of the inner pedal. A raised structure is provided below the inner edge of the inner pedal, and together with the retaining bar, the raised structure forms a support foot.

[0007] In a preferred embodiment of the present invention, a plurality of friction lines are provided on the inner pedal.

[0008] The beneficial effects of the present invention are as follows: the present invention is an improvement on the existing aluminum-iron composite sill structure; on the one hand, the top of the sill bracket is folded inwardly toward each other to form a support structure with a larger contact area with the sill body; on the other hand, a special limit seat is provided on the sill body for the support structure, which effectively reduces the relative friction between the top of the sill bracket and the sill body after force is applied, and significantly reduces the noise generated during operation; in addition, two anti-slip structures, an anti-slip boss structure and an anti-slip eaves, are provided on the sill door groove, which effectively improves the connection stability between the floor door and the sill; in this way, the floor door is constrained longitudinally and transversely at the same time during movement, which effectively improves the stability and safety of the movement, and significantly reduces the noise generated during movement.

The top of the anti-slip eaves 1010 is on the same plane as the tabletop of the anti-slip card platform 1012. The anti-slip eaves 1010 and the anti-slip card platform 1012 together form two anti-slip protections, which effectively improve the safety of the elevator door panel moving in the bottom groove. A positioning strip 108 is provided under the outer pedal 101. The positioning strip 108 and the retaining edge structure 107 together form a support foot holder. The bottom groove plate 105 continues to extend to the back side of the inner support plate 104 to form a bolt connection plate 106. The sill bracket 2 includes a bottom support plate 201, an outer support plate 202 and an inner support plate 203. The outer support plate 202 and the inner support plate 203 are respectively arranged vertically at both ends of the bottom support plate 201.
