Description

Technical Field

[0001] The utility model relates to the technical field of elevator sills, and more specifically, to an anti-falling elevator sill structure. Background Art

[0002] An elevator is a vertical lift powered by an electric motor and equipped with a car, used to transport people or goods in multi-story buildings. The elevator sill is installed between the elevator doors, which serves as a limit and guide for the operation of the elevator car doors and floor doors.

[0003] However, there are various types of elevator sill structures in the prior art. For example, utility model patent CN217398196U relates to a novel anti-slip layer door sill structure. The utility model sets an anti-slip door shoe assembly between the door panel and the sill groove. During the opening and closing movement of the door panel, the lower part of the door panel slides in the sill groove. At this time, the sliding block plays a guiding role, and the anti-slip mechanism plays a limiting role. When the door panel receives a large impact, the anti-slip mechanism prevents the door panel from slipping out of the sill groove, thereby solving the problem of the sliding block slipping out of the sill groove.

[0004] The elevator sill structure is provided with a sill groove for the sliding block to move. During long-term use, dust and foreign matter are easily accumulated in the sill groove. If the impurities are not cleaned in time, the elevator door may become stuck in operation. In severe cases, the sliding block may detach from the sill structure. In order to avoid this phenomenon, it is necessary to design an anti-detachment elevator sill structure that is easy to clean. Utility Model Content

The anti-slip protrusion 6 is set to prevent the slider 9 from escaping from the guide groove 5, while the two anti-slip protrusions 6 reduce the gap between the front connecting plate 2 and the rear connecting plate 3. Therefore, by using the narrow accommodating groove 8 and the setting of the inclined surface 7 on the anti-slip protrusion 6, the small gap can reduce the probability of dust and impurities falling into the guide groove 5, and the inclined surface 7 is used to block the dust and impurities close to the accommodating groove 8 to avoid the accumulation of dust and foreign matter in the guide groove 5 and the elevator door from being stuck. The bottom of the front connecting plate 2 is fixedly connected with a support plate 20, and the shape of the support plate 20 is L-shaped. A plurality of anti-slip strips 21 are arranged on the top of the front connecting plate 2. The anti-slip strips 21 are used to provide anti-slip protection for users who step on the smooth front connecting plate 2.
