[0031] like Figure 1 to Figure 4 As shown, a flap device between an external elevator and a floor of a construction site in this embodiment comprises a driving unit 1, a hinged rod 4, a shielding member 5 and a flap 6, wherein the driving unit 1 is fixed on the inner side 21 of the external elevator 2, the peripheral side of the flap 6 comprises a hinged side and two parallel and oppositely arranged connecting sides, the hinged side of the flap 6 is hinged on the bottom side of the entrance of the external elevator 2, the shielding member 5 is two and vertically fixed on the two connecting sides respectively, the hinged rod 4 is arranged obliquely and the upper end is hinged to the driving end of the driving unit 1, and the lower end of the hinged rod 4 is hinged to the connecting side; wherein the driving unit 1 drives the hinged rod 4 to extend from the external elevator 2 or to be retracted from the external elevator 2, thereby driving the flap 6 to flip outward to open or flip inward to be retracted, and driving the shielding member 5 to extend from the external elevator 2 or to be retracted from the external elevator 2. The use of the driving unit can improve the problem that the existing flap needs to be manually pushed or operated when opening, which is time-consuming, labor-intensive, and inconvenient to use. The shielding member 5 is located in the gap between the external elevator 2 and the floor, and is used for shielding and protecting, thereby improving the safety of walking. After the shielding member is folded, the shielding member is stored inside the external elevator, thereby preventing the construction personnel from touching it, thereby improving the safety of the flap being unfolded.

[0037] Specifically, the side of the protection cavity facing the elevator entrance is an open structure.

[0038] like Figure 1 and Figure 2 As shown, the horizontal plate 22 of this embodiment is provided with a control button 31 and a battery 3, and the control button 31 and the battery 3 are electrically connected to the drive unit 1 respectively. The battery 3 can provide power support for the drive unit 1, thereby avoiding the problem that the external elevator cannot be used due to an unexpected power outage. At the same time, the control button 31 can start the drive unit 1 to work, reducing the manual participation in the opening of the flap, which is more time-saving and labor-saving.

[0039] like Figure 2 to Figure 4 As shown, a specific scheme of this embodiment is that the driving part 1 includes a screw nut driving assembly; the screw nut driving assembly includes a screw 11, a slider 12, a guide rod 13, a first fixed plate 15, a second fixed plate 16 and a motor 14, the first fixed plate 15 and the second fixed plate 16 are arranged relatively and fixed at the front and rear positions of the inner side surface 21 of the external elevator 2, the two ends of the screw 11 are respectively rotatably connected with the first fixed plate 15 and the second fixed plate 16, the output shaft of the motor 14 is fixedly connected to one end of the screw 11 and the output shaft of the motor 14 is coaxially arranged with the screw 11, the two ends of the guide rod 13 are respectively vertically fixedly connected with the first fixed plate 15 and the second fixed plate 16, the screw 11 and the guide rod 13 are both arranged horizontally, the slider 12 is threadedly connected to the screw 11 and slidably cooperates with the guide rod 13, and the upper end of the hinged rod 4 is hinged to the lower end of the slider 12.

[0040] Specifically, the control button 31 and the battery 3 are electrically connected to the motor 14. The specific models and specifications of the motor 14, the battery 3 and the control button 31 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field.

The provision of the articulated ear plate and the articulated sleeve facilitates articulation with the articulated rod.

[0042] like Figure 1 and Figure 2 As shown, the shielding member 5 of this embodiment is a grid-shaped shielding plate. Specifically, the shielding member 5 includes a vertical rod and a horizontal rod, and the vertical rod and the horizontal rod are vertically fixedly connected to each other to form a grid-shaped shielding plate, and the lower end of the vertical rod is fixedly connected to the flap; the grid-shaped shielding plate is used, the structure is easy to implement, and it is convenient to observe the internal and external conditions.

[0043] When the flap device between the external elevator and the floor of the construction site of this embodiment is in use, after the external elevator reaches the designated floor, the drive unit is controlled by the control button, so that the slider can move back and forth on the lead screw and the guide rod of the drive unit. During the movement of the slider, the hinged rod is used to push the flap to unfold and rest on the corresponding floor. At this time, the shielding member is rotated out from the inside of the protective plate to block the gap between the floor and the elevator car. Conversely, the flap is pulled up by the reverse rotation of the drive unit and the shielding member is stored in the inside of the protective plate. This can reduce the number of construction personnel involved in the unfolding of the flap, save time and effort, and make it simpler and more convenient to use.

[0044] The flap device between the external elevator and the floor of the construction site of this embodiment can utilize the driving part to drive the hinged rod, and drive the flap and the shielding member to extend from the external elevator or be retracted from the outside of the external elevator, so that the flap can be blocked in the gap between the floor and the external elevator, reducing the number of construction workers involved in the deployment of the flap, saving time and effort, and being simpler and more convenient to use.
