An elevator sill structure

Abstract

The utility model relates to elevator field, concretely relates to a kind of elevator trough sill structure without slot. Including door sill and the door sill of the door plate connection, the guide groove for the transverse movement of door plate is set up on the door sill, the door sill includes the sill body of side edge opening, the inside of the sill body is provided with mute wheel, the mute wheel is connected by bolt with connecting piece, the connecting piece is connected with the door plate. The utility model is by setting mute wheel inside the sill body instead of the slider in the prior art, connecting piece is connected with mute wheel by bolt, then it is connected with door plate by bolt, so that the movement of door plate moves in guide groove by mute wheel, therefore, when moving, no noise is generated, solve the problem that there is noise when slider moves horizontally in guide groove, and sliding is not smooth enough.

Description

Technical Field

[0001] This utility model relates to the field of elevators, specifically to a grooveless sill structure for elevators. Background Technology

[0002] Existing elevator sill door slider grooves are prone to debris falling into them, causing the door to jam when opening and closing. To address this issue, our company applied for patent number 2021220216019, entitled "A Utility Model Patent for an Elevator Sill Structure," which discloses an elevator sill structure including a door panel and a door sill connected to the door panel. The door sill has a guide groove with an opening facing downwards for the door panel to move. A slider is installed on the door panel, with one end bolted to the door panel and the other end slidably connected to the guide groove. The slider includes a slider body bolted to the door panel and a C-shaped clamp integrally formed with the slider body. The C-shaped clamp engages in the guide groove and can move laterally within the guide groove. While this prior art solves the problem of debris falling into the elevator sill, clogging the groove, and jamming the elevator door panel, it does not resolve issues such as high noise and insufficient smoothness when the door panel moves laterally in the guide groove via the slider body.

[0003] Therefore, there is an urgent need for a grooveless sill structure for elevators to solve the aforementioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides a grooveless sill structure for elevators, including a door panel and a sill connected to the door panel. The sill has a guide groove for the door panel to move laterally. The sill includes a sill body with a side opening. A silent wheel is provided inside the sill body. The silent wheel is connected to a connector by bolts. The connector is connected to the door panel.

[0005] Preferably, a stainless steel plate is bonded to the sill body using structural adhesive.

[0006] Preferably, the thickness of the stainless steel plate is 1.0 cm.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] This invention replaces the slider in the prior art by setting a silent wheel inside the sill body. The silent wheel is connected to the door panel by bolts using a connector, so that the door panel moves within the guide groove via the silent wheel. Therefore, no noise is generated during movement, which solves the problems of loud noise and insufficient smooth sliding when the slider moves laterally in the guide groove. Attached Figure Description

[0009] Figure 1 This is a schematic diagram showing the connection between the present invention and the door panel;

[0010] Figure 2 This is a schematic diagram of the structure of the sill body of this utility model. Detailed Implementation

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] See Figure 1-2 This utility model discloses a grooveless sill structure for an elevator, including a door panel 1 and a sill 2 connected to the door panel 1. The sill 2 has a guide groove 3 for the door panel 1 to move laterally. The sill 2 includes a sill body 21 with a side opening. A silent wheel 22 is provided inside the sill body 21. The silent wheel 22 is connected to a connector 24 by bolts 23. The connector 24 is connected to the door panel 1.

[0013] Furthermore, a stainless steel plate 4 is bonded to the sill body 21 with structural adhesive. The purpose of setting the stainless steel plate 4 is to improve the strength of the sill body 21 and at the same time protect the sill body 21.

[0014] Furthermore, the stainless steel plate 4 has a thickness of 1.0 cm. The thickness of 1.0 cm is to ensure that the door panel 1 can move on the sill body 21 without hindering its movement.

[0015] Specifically, this utility model replaces the slider in the prior art by setting a silent wheel inside the sill body. The silent wheel is connected to the door panel by bolts using a connector, so that the door panel moves within the guide groove via the silent wheel. Therefore, no noise is generated during movement, which solves the problems of loud noise and insufficient smooth sliding when the slider moves laterally in the guide groove.
