[0002] With the continuous development of urbanization, more and more high-rise buildings have sprung up. During the construction of high-rise buildings, falling objects from height are relatively common and one of the construction safety accidents with a relatively high incidence rate. In order to reduce the harm caused by falling objects to construction workers, at present, during the construction of high-rise buildings, safety flat nets will be installed around the building to intercept falling objects, and when installing the safety flat nets, hanging devices are required.

[0003] In the existing technology, such as the document with the publication number of CN220539276U, a hanging device for a construction safety flat net is disclosed. When the device in this document is used, the fixing plate needs to be fixedly installed at a specified position around the building through expansion bolts, etc. before the hanging device can be installed. However, during the process of hanging the flat net, multiple hanging devices need to be used in cooperation to install the flat net. The above-mentioned method of installing the fixing plate through expansion screws has relatively high requirements for the construction site, and the installation and disassembly of the expansion screws are also relatively complicated, which will reduce the efficiency of hanging the flat net and is not conducive to construction. Therefore, we propose a hanging device for a construction safety flat net. Content of the Utility Model

By rotating the internal thread sleeve, the fixed block is squeezed by the internal thread sleeve, so that the ends of the two internal thread clamping plates are in contact with each other. By holding the semi-circular knob and rotating the internal thread clamping plate, the two internal thread clamping plates are screwed down along the two external thread sleeves. At this time, the two external thread sleeves are squeezed and elastically bent towards the scaffolding support rod. The two external thread sleeves respectively push the pressing plate to generate extrusion on the outer wall of the scaffolding support rod, so that the external thread sleeve can be fixed on the scaffolding, and at the same time, the hanging device is installed.

[0013] 2. By fixing the connecting steel cable or pulling rope on the flat net to the hanging ring, when a falling object falls on the safety flat net, under the impact force, the connecting steel cable or pulling rope can first pull the hanging ring, and the hanging ring pulls the fixed rod to slide outwards along the installation sleeve. At this time, the limiting disc squeezes the first spring, and under the elastic force of the first spring, the impact force is absorbed first, avoiding the safety flat net being damaged due to excessive impact force and losing the protection effect.

A hinge seat 12 is rotatably connected to the end of the rotating shaft 11. By sleeving the two external-thread sleeves 2 on the scaffolding struts at the construction site respectively, and sleeving the two internal-thread clamping plates 1 on the outer walls of the two external-thread sleeves 2 respectively, under the pulling force of the first spring 9, the two internal-thread clamping plates 1 can be in close contact with the outer walls of the external-thread sleeves 2. By rotating the internal-thread sleeve 8, the fixed block 6 is extruded by the internal-thread sleeve 8, so that the ends of the two internal-thread clamping plates 1 are in contact with each other. By holding the half-ring knob 5 and rotating the internal-thread clamping plate 1, the two internal-thread clamping plates 1 are screwed down along the two external-thread sleeves 2. At this time, the two external-thread sleeves 2 are extruded and elastically bent towards the scaffolding strut.

[0022] As Figure 1 and Figure 5 shown in the figure, a mounting sleeve 13 is fixedly connected to the end of the hinge seat 12. A fixed rod 14 is slidably connected to the inner wall of the mounting sleeve 13. The end of the fixed rod 14 penetrates through the mounting sleeve 13 and extends to its outside. A hanging ring 17 is fixedly connected to the outer end of the fixed rod 14. A second spring 16 is sleeved on the circumferential outer wall of the fixed rod 14. A limiting disc 15 is fixedly connected to the inner end of the fixed rod 14. The limiting disc 15 is slidably connected to the inner wall of the mounting sleeve 13. One end of the second spring 16 is fixedly connected to the inner wall of the mounting sleeve 13, and the other end of the second spring 16 is fixedly connected to the limiting disc 15. Two mounting holes 18 are formed in the outer wall of the mounting sleeve 13. Guide rods 19 are fixedly connected to the inner walls of both mounting holes 18. Two limiting blocks 20 are fixedly connected to the outer wall of the limiting disc 15. The ends of both guide rods 19 penetrate through the limiting blocks 20 and are slidably connected to them.

[0023] Working principle: By sleeving two external thread sleeves 2 on the scaffolding support rods at the construction site respectively, and sleeving two internal thread clamping plates 1 on the outer walls of the two external thread sleeves 2 respectively, under the pulling force of the first spring 9, the two internal thread clamping plates 1 can be in close contact with the outer walls of the external thread sleeves 2. By rotating the internal thread sleeve 8, the fixed block 6 is squeezed by the internal thread sleeve 8, so that the ends of the two internal thread clamping plates 1 are in contact with each other. By holding the half-ring knob 5 and rotating the internal thread clamping plates 1, the two internal thread clamping plates 1 are screwed downward along the two external thread sleeves 2. At this time, the two external thread sleeves 2 are squeezed and elastically bent towards the scaffolding support rod. The two external thread sleeves 2 respectively push the abutting plates 4 to squeeze the outer wall of the scaffolding support rod, so that the external thread sleeves 2 can be fixed on the scaffolding, and at the same time, the hanging device is installed;

[0024] By fixing the connecting steel cable or pull rope on the safety net to the hanging ring 17, when a falling object falls on the safety net, under the impact force, the connecting steel cable or pull rope can first pull the hanging ring 17, and the hanging ring 17 pulls the fixed rod 14 to slide outward along the installation sleeve 13. At this time, the limit disk 15 squeezes the first spring 9. Under the elastic force of the first spring 9, the impact force is absorbed first, so as to avoid the safety net being damaged due to excessive impact force and losing the protection effect. When the limit disk 15 moves, it can drive the limit block 20 to slide along the outer wall of the guide rod 19. During the process, as the falling direction of the falling object changes, at this time, the hanging ring 17 will drive the installation sleeve 13 to rotate.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
