[0002] Housing construction projects refer to various types of housing buildings and their ancillary facilities and the supporting lines, pipelines, equipment installation projects and indoor and outdoor decoration projects. "Housing construction" refers to projects with roofs, beams, columns, walls, foundations and the ability to form internal spaces to meet people's needs for production, living, learning, public activities, etc. Housing construction projects are generally referred to as construction projects, which refer to the various technical work such as survey, planning, design, construction, installation and maintenance for the construction, reconstruction or expansion of housing buildings and ancillary structures, as well as the completed engineering entities.

[0003] The anti-fall device is used to ensure the safety of personnel in building construction projects. There is an anti-fall device for building construction with Chinese patent publication number CN219344113U, which installs a support frame and fixes two first U-shaped rods on the vertical wall with fasteners. According to the inclination angle of the building construction wall, the position of the slider is adjusted, and the support assembly cooperates with the second U-shaped rod to adjust the angle of the support frame. The support net is perpendicular to the building construction wall. The limiting mechanism fixes the first U-shaped rod and the second U-shaped rod. When heavy objects or construction workers fall into the support net from the construction wall, the support rods at both ends of the support net slide toward each other, driving the limit blocks to slide, and the spring shock absorbers buffer the adjacent limit blocks. However, the device is inconvenient to operate when adjusting the inclination angle and is not practical enough.

[0022] like Figures 1 to 4As shown, an anti-falling device comprises an anti-falling platform 1 and a slide 3 rotatably arranged at the rear ends of both sides of the anti-falling platform 1, a handle 6 is arranged at the bottom of the slide 3, a threaded rod 5 is vertically rotatably arranged in the slide 3, the bottom of the threaded rod 5 is connected to the handle 6, a slider 7 is arranged on the threaded rod 5 through a threaded sleeve 8, the slider 7 is slidably arranged in the slide 3, a support member is hinged on the slider 7, and the end of the support member away from the slider 7 is hinged to the front end of the anti-falling platform 1.

[0023] Two sets of slides 3 are fixed on both sides of the building, and then the two sets of handles 6 can be turned synchronously to rotate the threaded rod 5. The threaded rod 5 is screwed with the threaded sleeve 8 to make the slider 7 slide vertically inside the slide 3, so that the support member rotates and the anti-fall platform 1 flips. When the handle 6 stops screwing, the threaded rod 5 and the threaded sleeve 8 are self-locking and fixed, so that the anti-fall platform 1 is fixed accordingly and provides anti-fall protection. The screw-on and sliding matching adjustment method is adopted, and the support rod is hinged to assist in support, which meets the different support adjustments of the anti-fall platform 1 and improves convenience.

[0024] In this embodiment, a snap ring 21 is provided at the bottom of the threaded rod 5, and the snap ring 21 is fixedly provided in the slide 3. A sliding sleeve 16 is provided on the side wall of the lower end of the slide 3, and a slide rod 17 is slidably provided in the slide sleeve 16. A clamping block 18 and a pull tab 20 are provided at both ends of the slide rod 17, respectively. The clamping block 18 and the pull tab 20 are located in the slide 3 and outside the slide 3, respectively. A contraction spring 19 is sleeved on the slide rod 17, and the two ends of the contraction spring 19 are connected to the pull tab 20 and the outer wall of the slide sleeve 16, respectively, and the clamping block 18 abuts against the snap ring 21. Holding the pull tab 20, the slide rod 17 overcomes the elastic force of the contraction spring 19 and slides in the slide sleeve 16 in a direction away from the threaded rod 5, so that the clamping block 18 can be separated from the snap ring 21, which facilitates the position adjustment of the slider 7. When the pull tab 20 is released, the contraction spring 19 can be elastically contracted, so that the clamping block 18 presses against the snap ring 21, thereby preventing the threaded rod 5 from rotating and improving stability.

[0025] In this embodiment, a restraining plate 4 is disposed on the top of the slide 3 , and the restraining plate 4 is rotatably connected to the anti-falling platform 1 via a movable shaft 2 .

[0026] In this embodiment, an articulated frame 19 is arranged on the slider 7, an articulated frame 2 13 is arranged on the anti-fall platform 1, and the support member includes an oblique support rod 12, an articulated block 11 and an articulated block 2 15, and the articulated block 11 and the articulated block 2 15 are respectively arranged at both ends of the oblique support rod 12, the articulated block 11 is rotatably connected to the articulated frame 19 through an articulated shaft 10, and the articulated block 2 15 and the articulated frame 2 13 are rotatably connected through an articulated shaft 2 14.

[0027] In this embodiment, a grease nozzle 22 is also provided at the front end of the slide block 7, and the grease nozzle 22 is connected to the inner wall of the threaded sleeve 8. Oil can be injected into the inner wall of the threaded sleeve 8 through the grease nozzle 22 for easy lubrication.

[0028] The oiling nozzle 22 is provided with an oiling cap 23, and one end of the oiling nozzle 22 away from the slider 7 is detachably connected to the oiling cap 23. After the oiling cap 23 is installed, the inside of the oiling nozzle 22 can be sealed and protected to avoid dust pollution and improve reliability.

[0029] In this embodiment, an information plate 24 is provided on the side wall of the anti-falling platform 1. The information plate 24 can display device information, facilitate reading, distinguishing, installing and using, and improve convenience.

[0030] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
