[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-4 As shown, a new type of elevator sill includes a bottom plate 1, vertical plates 2 are respectively arranged on both sides of the upper surface of the bottom plate 1, and extension plates 3 are respectively arranged on the upper ends of the two vertical plates 2, and a side plate 4 is arranged on one side of one of the vertical plates 2. It also includes a sill bracket 5, and the sill bracket 5 is connected to the side plate 4 by a fastener. The fastener includes a fixed part 6 and a movable part 7, and the fixed part 6 is fixed on the side plate 4.

[0019] like Figure 1 and Figure 2 As shown, it is a schematic diagram of the structure of a traditional sill and a sill bracket 5. Figure 1 In the state, in order to enable the movable bolts 9 and the movable nuts 10 to fix the sill and the sill bracket 5 together, it is necessary to open a countersink inside the bottom plate 1, which not only complicates the processing process, but also allows pedestrians to directly observe the movable bolts 9 in the countersink when passing through the sill, affecting the aesthetics. Figure 2 In this state, it is necessary to process a groove 11 at the lower part of the base plate 1. The structure of the sill is complex and the processing is difficult. It also increases the overall height of the sill, places high requirements on the installation position, and may even be impossible to install. It is also relatively difficult for the movable bolt 9 to enter the groove 11, affecting the operation.

[0020] In this specific embodiment, by providing the side plate 4, the connection between the sill and the sill bracket 5 can be replaced by the connection between the side plate 4 and the sill bracket 5. Since there is no need to open a sink groove on the bottom plate 1, the thickness of the bottom plate 1 can be reduced, which can be relatively Figure 1The height of the sill in the further reduced; compared with Figure 2 The sill in the embodiment of the present invention omits the position of the card slot 11, which can reduce the height of the sill. Figure 1 and Figure 2 Both methods can reduce the complexity of the processing steps. At the same time, the fixing portion 6 in the fastener is fixed on the side plate 4 to prevent the parts from being lost.

[0021] Furthermore, the fixed part 6 is a single-headed stud, and the movable part 7 is a nut. The single-headed stud is fixed to the lower surface of the side panel 4. A through hole for the single-headed stud to pass through is opened on the sill bracket 5. The nut fixes the sill bracket 5 to the side panel 4 by cooperating with the single-headed stud. A single spiral is opened on the outer surface of the single-headed stud, which is fixed to the lower surface of the side panel 4 by riveting. When fixing the sill and the sill bracket 5, it is only necessary to pass the single-headed stud on the side panel 4 through the through hole on the sill bracket 5, and the sill bracket 5 can be fixed to the sill through the threaded connection between the nut and the single-headed stud.

[0022] Furthermore, the fixing part 6 is a nut, the movable part 7 is a bolt, the outer surfaces of the sill bracket 5 and the side panel 4 are provided with through holes, the nut is arranged on the upper surface of the side panel 4 and is through-connected with the through hole on the side panel 4, the bolt is fixed to the side panel 4 by threaded connection with the nut, the bolt is fixed to the upper surface of the side panel 4 by welding, when the sill and the sill bracket 5 are fixed together, the sill is first placed inside the sill bracket 5, and the through holes on the sill and the sill bracket 5 are made to overlap with each other, and then the bolt is passed through the through hole and threadedly connected with the nut, thereby completing the fixation of the sill and the sill bracket 5.

[0023] Furthermore, it also includes a gasket 8, which is located between the movable part 7 and the sill bracket 5. When the gasket 8 located between the movable part 7 and the sill bracket 5 is compressed, the gasket 8 can provide a reaction force, so that the movable part 7 and the sill bracket 5 are always kept in a tensioned state, thereby improving the connection stability between the movable part 7 and the fixed part 6.

[0024] The device can reduce the difficulty of processing the sill through the side plate 4, and also facilitates lowering the height of the sill. The fixing part 6 is installed on the side plate 4, which can reduce the looseness of the parts and effectively reduce the possibility of losing the parts.

[0025] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
