[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-5 As shown, a sill structure for a passenger elevator includes a sill body 1, the sill body 1 is provided with a guide groove 2 and a movable groove 3, a plurality of connecting parts are provided inside the movable groove 3, the connecting parts include two top clamps 4, the two clamps 4 are provided with through holes, a cylinder 5 is provided between the two clamps 4, the cylinder 5 is provided with a threaded hole that penetrates the through holes on the clamps 4, protrusions 6 are respectively provided on both sides of the bottom of the movable groove 3, two clamps 4 are located on both sides of the protrusion 6, one of the clamps 4 is always in contact with the protrusion 6, and the other clamp 4 is always in contact with the movable groove 3.

[0019] The splint 4 can deflect in the movable groove 3, but the deflection angle is limited. When the bolt 8 is threadedly connected to the cylinder 5, when the splint 4 deflects to a certain angle, the splint 4 will not rotate with the bolt 8, and the deflection angle of the splint 4 is less than 45°.

[0020] The presence of the protrusion 6 can increase the height of the cylinder 5 , thereby increasing the connection stability with the bolt 8 .

[0021] When installing the sill body 1, first fix the support frame 10 on the elevator shaft wall. The support frame 10 has a reserved hole. Then, fix the sill body 1 to the support frame 10 through the reserved hole on the support frame 10. When installing the sill body 1, different installation forms can be selected according to the length of the bolt 8. When the length of the bolt 8 body can use the nut 9, first adjust the angle of the bolt 8 so that the head of the bolt 8 is above the rod body of the bolt 8, and then thread the rod body of the bolt 8 onto the cylinder 5. Since the sill body 1 is inconvenient to move after being placed on the support frame 10, it is necessary to place all the connecting parts into the movable groove 3 at one time, and then align all the bolts 8 with the reserved holes and pass through the reserved holes, and then fix the sill body 1 to the support frame 10 by cooperating with the nut 9 and the bolt 8.

[0022] When the length of the bolt 8 is too short to use the nut 9, first place the connecting part into the movable groove 3, then move the connecting part to a suitable position so that the cylinder 5 on the connecting part is aligned with the reserved hole on the support frame 10, then adjust the angle of the bolt 8 so that the head of the bolt 8 is located below the rod of the bolt 8, then pass the rod of the bolt 8 through the reserved hole on the support frame 10, then thread the bolt 8 into the cylinder 5, and tighten the bolt 8 to fix the sill to the support frame 10. Since the bolt 8 moves upward from the bottom of the support frame 10, after the sill body 1 is placed on the support frame 10, the bolts 8 can be installed one by one to improve the convenience of installation.

[0023] Furthermore, a clamping slot 7 for accommodating the clamping plates 4 is provided at the lower end of the movable slot 3 , wherein one clamping plate 4 is located on the upper surface of the protrusion 6 , and the other clamping plate 4 is located inside the clamping slot 7 .

[0024] Furthermore, the depth of the slot 7 is greater than the thickness of the splint 4. When the splint 4 is located in the slot 7, the splint 4 will not be in direct contact with the support frame 10, and there is no friction between the two. In the process of fixing the sill body 1 on the support frame 10, the position of the unfixed moving part can be easily adjusted, that is, the position of the cylinder 5 on the moving part can be adjusted so that the cylinder 5 is aligned with the reserved hole on the support frame 10.

[0025] Furthermore, the two ends of the splint 4 are respectively in contact with the inner walls of the movable groove 3. When the splint 4 is in the movable groove 3, the splint 4 will not deflect, thereby improving the efficiency of the connection between the bolt 8 and the cylinder 5 and avoiding the bolt 8 driving the cylinder 5 to rotate continuously when rotating.

[0026] Furthermore, the upper end of the movable groove 3 is configured to be arc-shaped, which can not only improve the stability of the movable groove 3 but also increase the internal space of the movable groove 3 to facilitate the installation of the bolt 8.

[0027] This sill structure can prevent the splint 4 and the cylinder 5 from continuously rotating with the bolt 8 when the bolt 8 rotates through the provided splint 4 and the cylinder 5, thereby improving the convenience of fixing the bolt 8. In addition, this sill can also adapt to bolts 8 of different lengths, and different fixing methods can be selected according to the different lengths of bolts 8, thereby improving the utilization rate of bolts 8 of different lengths and having a good use effect.

[0028] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
