[0037] Please refer to Figures 1 to 7The utility model provides an elevator sill for guiding elevator door panels, comprising: a top plate 1, a bottom plate 2 and supporting side plates 3.

[0038] Specifically, support side panels 3 are provided on both sides of the top panel 1 in the width direction. The top panel 1 is arranged opposite the bottom panel 2, and the top panel 1 is connected to the bottom panel 2 via the support side panels 3. The bottom panel 2 is recessed toward the top panel 1 to form a first bolt mounting groove 4. The first bolt mounting groove 4 is used for installing external bolts, so that the elevator sill can be fixedly connected to other components of the elevator system via external bolts. The top panel 1 is recessed toward the bottom panel 2 to form a guide groove 5 extending along the length of the top panel 1. The guide groove 5 is used to connect to the elevator door panel to provide guidance for the elevator door panel. The side groove walls of the guide groove 5 are recessed in a direction away from the guide groove 5 body to form a hook-shaped anti-slip groove 6 that connects to the guide groove 5. The hook-shaped anti-slip groove 6 is used to hook with the elevator door panel embedded in the guide groove 5 to prevent the elevator door panel from slipping out of the guide groove 5.

[0039] In the present invention, on the one hand, by providing support side panels 3 on both sides of the top panel 1 in the width direction, the support side panels 3 connect the top panel 1 and the bottom panel 2, thereby replacing the bottom support plate of the traditional sill and playing a good supporting role. On the premise of ensuring the strength of the sill, the overall structure is made more compact. On the other hand, by further concavely forming the side groove wall of the guide groove 5 to form a hook-shaped anti-slip groove 6, the function of limiting the elevator door panel from slipping out of the guide groove 5 is also achieved. When the elevator door panel is hit by external force, the hook-shaped anti-slip groove 6 can be hooked with the anti-slip plate or the door slider plate on the elevator door panel, effectively reducing the risk of the elevator door panel slipping out and improving the safety of the elevator system. The elevator door panel is not shown in the figure.

[0040] Optionally, the shape of the hook-shaped anti-slip groove 6 can be set according to the shape of the anti-slip plate of the elevator door panel, the hook edge of the door slider plate or other anti-slip components on the elevator door panel, and there is no specific limitation on this. For example, please refer to Figure 1 and Figure 2 The hook-shaped anti-slip groove 6 can be recessed toward the supporting side panel 3 and then further recessed toward the top panel 1, forming a hook shape that tilts upward. A portion of the side groove wall of the guide groove 5 near the hook-shaped anti-slip groove 6 forms a hooking section 7. The hooking section 7 also serves as the side groove wall of the hook-shaped anti-slip groove 6 for hooking with the elevator door panel.

[0041] The utility model provides an embodiment for use as a sill for an elevator door. Figure 1 and Figure 2 Specifically, the bottom of the guide groove 5 is connected to the bottom of the first bolt installation groove 4. Preferably, the bottom of the guide groove 5 and the bottom of the first bolt installation groove 4 are integrally formed. The supporting side plates 3 on both sides have gaps with the side groove walls of the guide groove 5 and the side groove walls of the first bolt installation groove 4.

[0042] Furthermore, at least one anti-skid groove 11 may be provided along the length of the top of the top plate 1. For example, an anti-skid groove 11 may be provided on each side of the notch of the guide groove 5 on the top plate 1, extending along the length of the top plate 1. As will be appreciated, the anti-skid groove 11 can increase friction on the top surface of the top plate 1, thereby providing an anti-skid effect. Furthermore, when liquids or oils are present, the anti-skid groove 11 can also collect and store these impurities to a certain extent, providing even better anti-skid performance.

[0043] Furthermore, the edges of the first bolt mounting slots 4 can be provided with transverse bottom supports 41. On one hand, the bottom supports 41 can partially block the slots of the first bolt mounting slots 4, thereby limiting the position of the bolts installed in the first bolt mounting slots 4. On the other hand, the bottom supports 41 can also provide additional support, enhancing the stability and seismic resistance of the overall structure and reducing the impact of external shocks or vibrations on the structure.

[0044] Preferably, the top plate 1, bottom plate 2 and supporting side plates 3 are formed in one piece, thereby improving the overall structural strength. In other cases, the top plate 1, bottom plate 2 and supporting side plates 3 can also be connected separately.

[0045] Preferably, the top plate 1, the bottom plate 2 and the supporting side plates 3 all comprise aluminum alloy plates. In other cases, the top plate 1, the bottom plate 2 and the supporting side plates 3 may also be plates made of other metals, alloys, plastics or other materials, which are not specifically limited.

[0046] Optionally, the width of both the top plate 1 and the bottom plate 2 can range from 36 mm to 42 mm, and the width of the supporting side plates 3 can range from 27 mm to 31 mm. For example, the width of the top plate 1 can be 40 mm, the width of the bottom plate 2 can be 36 mm, and the width of the supporting side plates 3 can be 29 mm. Compared to existing sills with bottom support plates, this structure is more compact.

[0047] In a specific embodiment, please refer to Figures 3 to 5 The supporting side panels 3 can be recessed inward to form a second bolt mounting slot 8 adjacent to the guide slot 5 and the first bolt mounting slot 4. The second bolt mounting slot 8 is designed to accommodate external bolts, allowing the elevator sill to be laterally connected via external bolts, making this embodiment suitable for use as a universal sill for elevator car doors and landing doors. Other specific structures, such as the anti-slip groove 11, bottom support legs 41, and the dimensions and materials of the top and bottom panels 1 and 2, can refer to the sills used for elevator car doors described in the above embodiments.

[0048] For further information, please refer to Figure 6 A protrusion 81 may be provided in the second bolt installation groove 8 , and the protrusion 81 is used to abut against an external bolt installed in the second bolt installation groove 8 .

[0049] For example, the ridge 81 can be provided at the bottom of the second bolt mounting slot 8 along its length and project toward the notch of the second bolt mounting slot 8. In actual use, when the external bolt is connected to another component, it is easily affected by external forces and moved toward the bottom of the slot. The ridge 81 can abut against the external bolt to prevent it from retreating when connected to the other component, making installation and tightening easier. In this embodiment, the groove shape of the second bolt mounting slot 8 is suitable for hexagonal head bolts, and the external bolts are correspondingly hexagonal head bolts.

[0050] In other cases, please refer to Figure 7 A reinforcing rib 82 may be provided in the second bolt installation groove 8 , and the reinforcing rib 82 is also used to abut against an external bolt installed in the second bolt installation groove 8 .

[0051] For example, reinforcing ribs 82 can be connected to two opposing side walls of the second bolt mounting slot 8 to form a vertical support structure. In addition to limiting the retreat of the external bolts, the reinforcing ribs 82 also enhance the overall strength of the elevator sill, further improving the reliability and safety of the elevator sill. In this embodiment, the second bolt mounting slot 8 is configured to accommodate hexagonal head bolts, corresponding to the external bolts.

[0052] In a specific implementation, the groove wall of the second bolt installation groove 8 is connected to the groove wall of the guide groove 5, and / or the groove wall of the second bolt installation groove 8 is connected to the groove wall of the first bolt installation groove 4, and / or the groove wall of the guide groove 5 is connected to the groove wall of the first bolt installation groove 4. The connection can be understood as that the two grooves share the same structure as the groove wall.

[0053] For example, please refer to Figure 4 The bottom of the guide groove 5 is connected to the bottom of the first bolt mounting groove 4, and the bottom of the second bolt mounting groove 8 is connected to the side groove wall of the first bolt mounting groove 4. A gap exists between the bottom of the second bolt mounting groove 8 and the side groove wall of the guide groove 5. It can be understood that the groove walls of each groove play a role in strengthening the overall structural strength of the sill and are key to ensuring the sill has good support capabilities. Proper connection between the groove walls can ensure the structural strength of the sill while reducing material costs and making the overall structure more compact. In this embodiment, the groove shape of the second bolt mounting groove 8 is suitable for square neck bolts, and the external bolts are correspondingly square neck bolts.

[0054] In other embodiments, for example Figure 5 As shown, the groove bottom of the second bolt installation groove 8 can be connected to the side groove wall of the guide groove 5.

[0055] In summary, the elevator sill of the present invention provides supporting side panels 3 on both sides of the top panel 1 in the width direction, so that the supporting side panels 3 connect the top panel 1 and the bottom panel 2, thereby replacing the bottom support plate of the traditional sill, providing a good supporting effect, and making the overall structure more compact while ensuring the strength of the sill. In addition, by further concavely forming the side groove walls of the guide groove 5 to form hook-shaped anti-slip grooves 6, the present invention also achieves the function of preventing the elevator door panel from slipping out of the guide groove 5. When the elevator door panel is impacted by external force, the hook-shaped anti-slip grooves 6 can hook and connect with the anti-slip plate on the elevator door panel or the hook edge of the door slider plate, effectively reducing the risk of the elevator door panel slipping out and improving the safety of the elevator system.

[0056] Furthermore, the supporting side panels 3 can be recessed to form a second bolt mounting slot 8, making the present invention universally applicable to both car doors and landing doors. A ridge 81 or reinforcing rib 82 can be provided in the second bolt mounting slot 8 to prevent the external bolts from backing out when connected to other components, facilitating installation and tightening. This also enhances the overall strength of the sill, further improving its reliability and safety. The second bolt mounting slot 8 is designed to accommodate both square-neck bolts and hexagonal-head bolts, providing excellent adaptability.
