[0002] An elevator shaft is a dedicated shaft for installing elevators, and its size is determined according to the elevator type selection. Elevator tracks and counterweight tracks will be installed on the shaft wall of the elevator shaft, and door openings will be reserved for installing elevator doors. Elevator shafts often appear in medium and high-rise buildings and western-style houses. During the construction stage of the building, since the elevator has not been installed yet, the elevator shaft door openings are in an open state. In order to avoid safety accidents, anti-falling brackets are needed to isolate and protect the elevator shaft door openings.

[0003] In the Chinese utility model patent with the publication number CN217812732U, a building elevator shaft protection device is disclosed. After pushing the second support rod to fit against one side wall of the elevator shaft entrance and making the second positioning plate and the third positioning plate located on both sides of the wall respectively, put the hand through the gap between the second support rod and the protection rod, control the rotation of the threaded rod, which can drive the third positioning plate rotatably connected to the threaded rod to slide stably back and forth under the action of the limit rod, so that both the second positioning plate and the third positioning plate can be closely attached to the wall, enabling the positioning of the device and having stronger protection ability;

[0004] After retrieval, it is found that the elevator shaft protection device proposed in the comparative document still has some defects and deficiencies in actual application: the above device is relatively tall and does not have the function of folding and storing, which is inconvenient during the transfer and transportation inside the building. Moreover, the above device is provided with more connecting rods, resulting in weak anti-impact ability of the device, and the safety protection effect of the device will also be affected. Therefore, it is urgent to improve the existing elevator shaft protection anti-falling bracket to provide an elevator shaft protection anti-falling bracket. Content of the Utility Model

A second support rod 7 is provided behind the first support rod 6. An adjusting assembly 8 is installed behind the second support rod 7. The top of the left vertical rod 2 is connected with a warning assembly 9.

[0026] On the basis of the above structure, groove-like structures are provided on both sides of the left sleeve column 1 and the right sleeve column 3 that are close to each other. The cross-section of the clamping sleeve 4 is arranged in a "concave" shape.

[0027] In this embodiment, by clamping the left and right clamping sleeves 4 on the walls on both sides of the elevator shaft respectively, it is convenient to stably install the device at the elevator shaft position.

[0028] On the basis of the above structure, both ends of the first support rod 6 are hinged to the left sleeve column 1 and the right vertical rod 5 respectively. Both ends of the second support rod 7 are hinged to the right sleeve column 3 and the left vertical rod 2 respectively. The lengths of the first support rod 6 and the second support rod 7 are equal and are distributed in an "X" shape.

[0029] In this embodiment, by using the settings of the first support rod 6 and the second support rod 7, it is convenient to stably support the left sleeve column 1 and the right sleeve column 3, and at the same time, it is convenient to control the expansion or folding of the bracket.

[0030] On the basis of the above structure, the adjusting assembly 8 includes a connection block 81, a threaded rod 82, a movable block 83, a first push rod 84 and a second push rod 85. The connection block 81 is located at the middle position behind the first support rod 6. A threaded rod 82 is connected to the inside of the connection block 81 by a bearing. A movable block 83 is threadedly sleeved on the outer side of the top end of the threaded rod 82. The front end of the movable block 83 is rotatably connected with the first push rod 84 and the second push rod 85.

[0031] On the basis of the above structure, both the first support rod 6 and the second support rod 7 are rotatably connected to the connection block 81. The first push rod 84 and the second push rod 85 are equal in length and are symmetrically arranged in a left-right offset manner with respect to the connection block 81. The bottom end of the first push rod 84 is hinged to the first support rod 6. The bottom end of the second push rod 85 is hinged to the second support rod 7.

[0032] In this embodiment, by rotating the threaded rod 82, the movable block 83 can be controlled to move vertically downward, and the first push rod 84 and the second push rod 85 can be used to push the first support rod 6 and the second support rod 7 to rotate synchronously and in opposite directions, so as to control the complete expansion or folding and storage of the bracket.

[0033] On the basis of the above structure, the warning component 9 includes a fixed box 91, a vertical shaft 92, a scroll spring 93, a woven belt 94, a fixed rod 95 and a fluorescent strip 96. The fixed box 91 is fixed to the top of the left vertical rod 2. A vertical shaft 92 is arranged inside the fixed box 91. Both the upper and lower ends of the vertical shaft 92 are connected to the fixed box 91 through scroll springs 93. A woven belt 94 is adhesively bonded to the outer side of the middle part of the vertical shaft 92. One end of the woven belt 94 far from the vertical shaft 92 is fixedly connected to a fixed rod 95. The fixed rod 95 is fixed to the top of the right vertical rod 5. A plurality of fluorescent strips 96 are adhesively bonded to the outer surface of the woven belt 94 at equal intervals.

[0034] On the basis of the above structure, the woven belt 94 forms a winding structure on the outer side of the vertical shaft 92.

[0035] In this embodiment, when the control device is unfolded and used, the woven belt 94 can be pulled out from the fixed box 91. By using the plurality of fluorescent strips 96 arranged at equal intervals on the surface of the woven belt 94, effective warning can be realized even in a dimly lit area.

[0036] The working principle of the present utility model is as follows:

[0037] When in use, first place the device at the position of the elevator shaft door opening, and manually rotate the threaded rod 82 to control the movable block 83 to move stably downward along the vertical direction and approach the connecting block 81. At this time, the first push rod 84 and the second push rod 85 can be used to push the first support rod 6 and the second support rod 7 to rotate synchronously in opposite directions, so as to push the left sleeve column 1 and the right sleeve column 3 away from each other. At the same time, the left vertical rod 2 and the right vertical rod 5 can also be pulled to rise relative to the left sleeve column 1 and the right sleeve column 3, so that the bracket changes from the Figure 1 shown state to the Figure 3 shown state in the figure, the device can be completely unfolded, and the left and right two clamping sleeves 4 can be respectively clamped on the walls on both sides of the elevator shaft to complete the stable installation of the device. Similarly, by rotating the threaded rod 82 in the reverse direction, the movable block 83 is controlled to rise, which is convenient for folding the bracket, reducing the height and volume of the bracket, and facilitating the carrying and transfer transportation of the bracket;

[0038] When the bracket is controlled to be unfolded and used, the fixed box 91 and the fixed rod 95 move away from each other, and the woven belt 94 can be automatically pulled out from the fixed box 91. By using the structure as shown in Figure 4A plurality of fluorescent strips 96 are equidistantly arranged on the surface of the middle braided belt 94, which is convenient for effective warning even in areas with dim light. And when the control device is folded and contracted, the scroll spring 93 can make the vertical shaft 92 automatically rotate to wind up the released braided belt 94. Moreover, this bracket supports and positions the left sleeve column 1 and the right sleeve column 3 through the first support rod 6 and the second support rod 7. The number of connecting rods is small. When the bracket is accidentally collided, the impact force can be directly transmitted to the left sleeve column 1 and the right sleeve column 3 through the first support rod 6 and the second support rod 7 and transferred to the building wall. The impact resistance of the device is stronger and the support safety is higher.

[0039] The above are only the preferred specific embodiments of the present invention, and are not intended to limit the protection scope of the present invention; any equivalent changes, modifications, substitutions and variations made by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments shall fall within the protection scope determined by the claims.
