[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figure 1-Figure 8 As shown, an elevator door safety warning device includes a base 1, and two support arms 2 are hinged at the upper and lower ends of the base 1. The suspended ends of the support arms 2 are also hinged with claws 5 for clamping the corners of the elevator door. The base 1 is also provided with a driving component for driving the support arms 2 to extend and retract, and the support arms 2 are provided with warning signs.

[0032] As a specific embodiment, the driving assembly includes a screw rod 5 rotatably disposed on the base 1 , the threaded end 53 of the screw rod 5 is cooperatively connected to a connecting seat 4 , and the connecting seat 4 is hinged to the suspended end of the support arm 2 through a connecting rod 3 .

[0033] Specifically in this embodiment, two screw rods 5 are used, and support seats 12 are respectively provided at the upper and lower ends of the base 1, and the two screw rods 5 are respectively rotatably provided on the two support seats 12; a nut seat 41 vertically corresponding to the support seat 12 is provided on the connecting seat 4, and the threaded end 53 of the screw rod 5 is threadedly connected with the nut seat 41. The connecting seat 4 located at the bottom is hinged with the corresponding two support arms 2 located at the bottom through two connecting rods 3; the connecting seat 4 located at the top is hinged with the corresponding two support arms 2 located at the top through two connecting rods 3. It should be noted that both ends of the connecting rod 3 are connected to the support arm 2 and the connecting seat 4 in a hinged form.

[0034] Specifically in the present embodiment, an avoidance hole (not shown in the figure) for the screw 5 to pass through is opened on the support seat 12, and a connecting end 51 coaxially arranged with the threaded end 53 is provided at one end of the screw 5 away from the threaded end 53, and the connecting end 51 is rotatably arranged in the avoidance hole; limiting plates 54 are respectively provided on the connecting end 51 and on both sides of the avoidance hole, and the axial movement of the screw 5 is limited by the limiting plates 54, so that the screw 5 can only rotate on the support seat 12.

[0035] As a specific implementation method, Figure 1 and Figure 8 As shown, the claw 6 is configured as an angle plate structure to facilitate clamping the corner of the main elevator door. When the driving support arm 2 is extended outward, the claw 6 can be pressed against the corner of the elevator door. The entire extended support arm 2 and the connecting rod 3 form a blocking protection frame to prevent people from accidentally falling into the elevator shaft.

[0036] Furthermore, a non-slip rubber pad (not shown in the figure) is provided at the clamping mouth of the clamping claw 6 to increase the connection friction between the clamping claw 6 and the corner of the elevator door wall to prevent the clamping claw from falling off.

[0037] Furthermore, the connection end 51 and the threaded end 53 are transitionally connected via a bending portion 52 , and the bending portion 52 forms a crank for driving the screw rod 5 to rotate, so that the screw rod 5 can be quickly rotated and adjusted.

[0038] Furthermore, if Figure 4 As shown, two bases 1 are used, the two bases 1 are rotatably connected to each other, a fixing component is arranged between the two bases 1, and one base 1 is correspondingly connected to two support arms 2.

[0039] Specifically in this embodiment, Figure 5 As shown, the two bases 1 are rotatably connected via a hinge 13 .

[0040] As a specific embodiment, the fixing component is a latch 11 disposed between the two bases 1, and the two bases 1 are fixedly connected by the latch 11 when they are horizontally unfolded. The purpose of this design is that when the warning device is not in use, the support arm 2 is collapsed (such as Figure 4 and Figure 5 As shown), the two bases 1 can be further folded (as shown Figure 6 and Figure 7 As shown), the four support arms 2 are all folded together to reduce the space occupied by the device and facilitate storage and carrying.

[0041] Working principle: (such as Figure 8When in use, first unfold the two bases 1 and fix them with the latch 11 so that the two bases 1 cannot rotate relative to each other, then adjust the support arm 2 with the claws 6 to unfold outward by rotating the two screws 5. When the distance between the two adjacent claws 6 on the left and right is close to the width of the elevator door, clamp the claws 6 at the corner of the elevator door, and continue to adjust the screws 5 until the support arm 2 presses all the claws 6 tightly against the corner of the elevator door. At this time, the unfolded support arm 2 and the connecting rod 3 form a protective frame to prevent people from accidentally falling into the elevator shaft. At the same time, warning signs such as "Construction Danger" and "Do Not Approach" are set on the support arm 2 to warn nearby people of the danger here.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
