DETAILED DESCRIPTION

[0020] 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.

[0021] The utility model provides Figure 1-3 The illustrated construction safety support device comprises a support column 1, which is a wooden column used to support the formwork of the ceiling of the construction. The bottom of the outer wall of the support column 1 is slidably sleeved with a support sleeve 21, and the bottom of the support sleeve 21 is in a sealed state, so that the support sleeve 21 is located inside the connecting sleeve 22, so that the bottom of the support column 1 can be supported and limited. The outer wall of the support sleeve 21 is slidably sleeved with a connecting sleeve 22, and the bottom of the connecting sleeve 22 is fixedly connected with a bottom plate 23. The bottom plate 23 can increase the contact area between the connecting sleeve 22 and the ground, thereby improving the stability of the connecting sleeve 22 and the support sleeve 21 supporting the support column 1. An adjusting component 24 for adjusting the height of the support sleeve 21 is provided at the bottom of the inner cavity of the connecting sleeve 22, so that the height of the support sleeve 21 inside the connecting sleeve 22 can be changed under the action of the adjusting component 24, so that the support sleeve 21 is at a corresponding height to support and limit the support column 1, and the adjusting component 24 includes an adjusting screw 2 41. Connecting block 242 and connecting plate 243. The adjusting screw 241 is rotatably connected to the inside of the connecting sleeve 22. The outer wall of the adjusting screw 241 is provided with opposite external threads. The connecting block 242 is threadedly inserted and sleeved on the outer wall of the adjusting screw 241. The connecting plate 243 is tilted and rotatably arranged between the connecting block 242 and the supporting sleeve 21. There are two connecting blocks 242 and two connecting plates 243. The two connecting plates 243 are tilted and symmetrically arranged. Since the external threads at both ends of the outer wall of the adjusting screw 241 are in opposite directions, the adjusting screw 241 can be rotated to make the two connecting blocks 242 move relative to or away from each other, thereby driving the bottoms of the two connecting plates 243 to move relative to or away from each other. The bottoms of the two connecting plates 243 move relative to each other, and the top of the connecting plate 243 pushes the supporting sleeve 21 to slide upward inside the connecting sleeve 22. On the contrary, the bottoms of the two connecting plates 243 move away from each other, and the tops of the two connecting plates 243 drive the supporting sleeve 21 to slide downward inside the connecting sleeve 22.

[0022] Specifically, the top of the base plate 23 is fixedly connected to a limit plate 246, and a sliding groove is provided at the bottom of the connecting block 242. The outer wall of the limit plate 246 is slidably engaged with the inner cavity of the sliding groove. The limit plate 246 can not only ensure the stability of the linear sliding of the connecting block 242 inside the connecting sleeve 22, but also support the connecting block 242 under the extrusion force, thereby preventing the extrusion force on the connecting block 242 from causing pressure loss to the adjusting screw 241. A first hinge 244 is provided on the top of the connecting block 242, and a second hinge 245 is symmetrically provided on the bottom of the support sleeve 21. The bottom of the connecting plate 243 is rotatably connected to the connecting block 242 through the first hinge 244, and the top of the connecting plate 243 is rotatably connected to the support sleeve 21 through the second hinge 245.

[0023] Furthermore, a connecting disc 248 is provided at one end of the adjusting screw 241, and a limiting rod 249 is symmetrically fixedly connected to one side of the connecting disc 248. A limiting groove is provided on one side of the connecting sleeve 22, and the outer wall of the limiting rod 249 is slidably engaged with the inner cavity of the limiting groove. The end of the adjusting screw 241 is fixedly connected with a knob 247, and a rectangular groove 2411 is provided on one side of the knob 247. Therefore, by docking the rectangular block tool with the rectangular groove 2411, the adjusting screw 241 can be driven to rotate. A connecting rod 2410 is slidably inserted and sleeved on one side of the adjusting screw 241. The end of the connecting rod 2410 is fixedly connected to the connecting disc 248, and the end of the connecting rod 2410 is fixedly connected to a fixing block 2412. The outer wall of the fixing block 2412 is slidably engaged with the inner cavity of the rectangular groove 2411, so that the connecting rod 2410 can be limited, and then the connecting rod 2410 is limited by the fixing block 2412 to the knob 247, thereby ensuring the stability of the adjusting screw 2411. When the supporting sleeve 21 and the connecting sleeve 22 support the supporting column 1, the stability of the adjusting screw 241 is ensured, and when the rectangular block tool is used to dock with the rectangular groove 2411, the fixing block 2412 can be squeezed, so that the fixing block 2412 drives the connecting disc 248 to move away from the connecting sleeve 22 through the connecting rod 2410, so that the limiting rod 249 is separated from the connecting sleeve 22, and the outer wall of the connecting rod 2410 is slidably sleeved with the limiting spring 2413, and the limiting spring 2413 is located on the side of the fixing block 2412 facing the connecting disc 248. When the rectangular block tool docked with the rectangular groove 2411 is pulled out, the limiting spring 2413 can give the fixing block 2412 a reset elastic force, so that the connecting rod 2410 drives the connecting disc 248 and the limiting rod 249 to move toward the connecting sleeve 22, so that the limiting rod 249 is slidably engaged with the limiting groove on the outer wall of the connecting sleeve 22, and the adjusting screw 241 is limited.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
