[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1, reference Figure 1-2 , which is the first embodiment of the present invention, and this embodiment provides a high-altitude anti-falling device for the edge of a roof, including, a base plate 101a contacts the support surface, and a support plate 101b is arranged perpendicular to the working surface, and a certain angle is formed between the two to provide a stable support structure. The locking screw 102 and the lower hanging point ring 103 are fixed on the base plate 101a, and are used to connect the clamping plate 201 and the safety equipment. The shift member 104 is installed on the support plate 101b, and can be flexibly adjusted according to the specific thickness of the wall to ensure that the device can effectively clamp the edge of the roof. Through the action of the locking screw 102 and the clamping plate 201, the device can be tightly fixed on the roof, and at the same time, the upper and lower hanging point rings are used to provide a safe connection point for the staff, thereby effectively preventing falling accidents during high-altitude operations.

[0033] Specifically, the support assembly 100 includes a base frame 101, a locking screw 102 fixedly mounted on the base frame 101, and a lower hanging point ring 103. A stopper 104 is installed at the end of the base frame 101, and the stopper 104 is used to adjust the clamping distance according to the wall thickness.

[0034] Furthermore, the base frame 101 includes two parts, a bottom plate 101a and a support plate 101b, which are connected at a certain angle. The locking screw 102 and the lower hanging point ring 103 are fixedly installed on the bottom plate 101a, and the shift member 104 is installed on the support plate 101b.

[0035] Furthermore, the base frame 101 further includes a first anti-slip pad 101 c disposed on the top of the bottom plate 101 a , and the locking screw 102 is located between the first anti-slip pad 101 c and the lower hanging point ring 103 .

[0036] Operation process: First, make sure that all components are complete, including the base frame 101, the locking screw 102, the lower hanging point ring 103 and the gear piece 104. Check whether these components are intact. Place the base frame 101 at the designated position on the edge of the roof so that the bottom plate 101a can firmly contact the support surface and the support plate 101b is perpendicular to the working surface. This can ensure the stability of the device after installation. Select a suitable through hole 104b according to the actual wall thickness, and then let the gear rod 104c pass through the corresponding through hole 104b on the adjustment plate 104a. This step is to adapt to walls of different thicknesses to achieve the best clamping effect. Use the pin rod 104d to lock through the pin hole at the front end of the gear rod 104c to ensure that the gear rod will not loosen or shift, thereby fixing the position of the gear piece. Insert the clamping plate 201 through the locking screw 102 so that one end of it contacts the gear piece 104 and the other end is in close contact with the roof. Next, rotate the locking nut 202a and the washer 202b to apply a pre-tightening force to the clamping plate 201 until the entire device is firmly clamped to the roof. Connect the safety rope or fall arrester to the upper hanging point ring 203 or the lower hanging point ring 103 to ensure a reliable connection. This is to provide immediate safety protection in the event of an accident. Confirm again that all connecting parts have been correctly installed and locked in place, especially the connection between the shift piece 104 and the clamping plate 201, and pay special attention to its stability. Make sure that the second anti-skid pad 204 made of rubber fits tightly against the wall with the first anti-skid pad 101c to increase friction and prevent the device from sliding.

[0037] Example 2, reference Figure 1-2, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the shift member 104 is composed of an adjustment sheet 104a, and a plurality of through holes 104b are provided on the adjustment sheet 104a, allowing the shift rod 104c to pass through different through holes as needed to adapt to walls of different thicknesses. This design enables the device to be suitable for installation requirements in a variety of scenarios. The locking screw 102 is designed to have an inclination angle that is the same as the angle between the bottom plate 101a and the support plate 101b, so that the pressure applied by the clamping plate 201 can be evenly distributed, thereby improving the stability of the entire device. The front end of the shift rod 104c is designed with a pin hole of a specific size, which is used to cooperate with the pin rod 104d to fix the shift rod 104c, thereby ensuring that the position of the shift member 104 will not change, thereby increasing the safety of the device. Through the synergistic effect of the above-mentioned components, the device can effectively clamp the edge of the roof, and at the same time use the upper and lower hanging point rings (upper hanging point ring 203 and lower hanging point ring 103) to provide a safe connection point for the staff, effectively preventing falling accidents during high-altitude operations.

[0038] Specifically, the shift member 104 includes an adjusting piece 104a disposed on the side wall of the support plate 101b, a through hole 104b is disposed on the side wall of the adjusting piece 104a, and a pin rod 104d is disposed on the side wall of the shift rod 104c.

[0039] Furthermore, the adjusting piece 104a is symmetrically mounted on the supporting plate 101b, and a middle portion thereof is provided with four groups of symmetrical through holes 104b for the shift lever 104c to pass through.

[0040] Furthermore, the locking screw 102 is fixedly mounted on the base frame 101 at an inclination angle that is the same as the angle between the base plate 101 a and the support plate 101 b .

[0041] Furthermore, a pin hole with a diameter greater than that of the pin rod 104d is designed at the front end of the shift rod 104c, and is used for the pin rod 104d to fix the shift rod 104c.

[0042] The rest of the structure is the same as that of Example 1.

[0043] Operation process: Confirm that all components are complete, including the base frame 101, locking screw 102, lower hanging point ring 103 and gear piece 104. Make sure these parts are not damaged. Place the base frame 101 at the designated position on the edge of the roof, ensure that the bottom plate 101a is firmly in contact with the supporting surface, and the support plate 101b is perpendicular to the working surface to form a stable installation foundation. Select a suitable through hole 104b according to the actual wall thickness. Pass the gear rod 104c through the selected through hole 104b on the adjustment plate 104a. The adjustment plate 104a is symmetrically installed on the support plate 101b, and four groups of symmetrical through holes 104b are provided in the middle part to adapt to walls of different thicknesses. A pin hole with a diameter larger than the diameter of the pin rod 104d is designed at the front end of the gear rod 104c. The pin rod 104d is used to pass through the pin hole to fix the gear rod 104c to ensure that it will not loosen or move. Use the locking screw 102 with the same inclination angle as the angle between the base plate 101a and the support plate 101b to insert the clamping plate 201. Make one end of the clamping plate 201 contact the shift piece 104, and the other end contact the roof. Rotate the locking nut 202a and the washer 202b to pre-tighten the clamping plate 201 until the entire device is firmly clamped to the roof. Connect the safety rope or fall arrester to the upper hanging point ring 203 or the lower hanging point ring 103 to ensure a reliable connection and provide safety protection for the staff. Confirm again that all connecting parts have been correctly installed and locked in place, especially the connection between the shift piece 104 and the clamping plate 201, and pay special attention to its stability. Make sure that the second anti-skid pad 204 made of rubber fits tightly against the wall with the first anti-skid pad 101c to increase friction and prevent the device from sliding.

[0044] Example 3, reference Figure 1-2 , which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that this embodiment particularly emphasizes the design optimization of the clamping assembly 200. The device achieves effective clamping of walls of different thicknesses and improves overall safety and stability through key components such as a clamping plate 201, a locking member 202 (including a locking nut 202a and a washer 202b), and a second anti-slip pad 204 made of rubber.

[0045] Specifically, the clamping assembly 200 includes a clamping plate 201 arranged at the top of the base frame 101, wherein the clamping plate 201 passes through the locking screw 102 and contacts the shift member 104 at one end, and is pre-tightened by the locking member 202 on the locking screw 102, and an upper hanging point ring 203 fixedly installed on the clamping plate 201 is connected to a safety rope or a fall arrester for use.

[0046] Furthermore, a second anti-skid pad 204 made of rubber is fixedly installed on the inner side of the pressing plate 201. The second anti-skid pad 204 is wedge-shaped and is used in conjunction with the first anti-skid pad 101c.

[0047] Furthermore, the locking member 202 includes a locking nut 202a and a washer 202b which are arranged on the top of the pressing plate 201, and the pressing plate 201 is pre-tightened by the locking nut 202a and the washer 202b.

[0048] Furthermore, the front end of the locking screw 102 is designed with a thread, which can cooperate with the locking nut 202a and the washer 202b to fix the clamping plate 201. A through hole with a diameter larger than the major diameter of the locking screw 102 is designed in the middle of the clamping plate 201, and the inner ring diameter of the washer 202b is larger than the diameter of the through hole in the middle of the clamping plate 201.

[0049] The rest of the structure is the same as that of Example 2.

[0050] Operation process: Check whether all components are complete, including the base frame 101, locking screw 102, lower hanging point ring 103 and gear piece 104. Place the base frame 101 at the edge of the roof where the anti-fall device needs to be installed. Make sure that the bottom plate 101a is firmly in contact with the supporting surface and the supporting plate 101b can be perpendicular to the working surface. According to the actual wall thickness, select a suitable through hole 104b, and pass the gear rod 104c through the corresponding through hole 104b on the adjustment plate 104a to adapt to different roof thicknesses. Use the pin rod 104d to lock through the pin hole at the front end of the gear rod 104c to ensure that the gear rod 104c will not loosen, and insert the clamping plate 201 through the locking screw 102 so that one end of the clamping plate 201 contacts the gear piece 104 and the other end contacts the roof. Rotate the locking nut 202a and the washer 202b to pre-tighten the clamping plate 201 until the entire device firmly clamps the roof. Connect the safety rope or fall arrester to the upper hanging point ring 203 or the lower hanging point ring 103 to ensure a reliable connection. Use the pin rod 104d to pass through the pin hole at the front end of the gear lever 104c to lock it, ensuring that the gear lever 104c will not loosen. Its clamping plate 201 passes through the locking screw 102, so that one end of the clamping plate 201 contacts the gear member 104, and the other end contacts the roof. Ensure that the second anti-skid pad 204 made of rubber material and the first anti-skid pad 101c are tightly attached to the wall.
