[0002] At present, in construction, protective nets are usually built around buildings, especially high-rise buildings, so that construction can be closed and the safety of workers can be enhanced through the protective nets. The protective net is a kind of construction equipment that can prevent objects on the construction site from falling and injuring workers. The building protective net must be inspected once a week during use, and debris must be cleaned up in time. When it is subjected to a large load impact, it should be replaced with a new net or inspected in time to see if there is serious deformation, wear, breakage, or detachment of the connection parts. After confirming that it is intact, it can continue to be used. The following problems exist in the existing technology:
[0003] Chinese patent document CN209653357U discloses a building safety protection net, which belongs to the field of construction engineering technology, including a protection net body and a storage box.

DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods:

[0027] The cooperation of the T-slot 21 and the T-block 22 is used to engage one safety net device with the other safety net device, thereby ensuring the accuracy of the left-right connection of the safety net devices. By splicing the two safety nets, the strip block 31 on the left side of one safety net device passes through the conical through slot 41 on the side of the fixing plate 4 on the right side of the other safety net device. The block 314 is pushed out of the groove 312 by the thrust of the spring 2 313 to form a snap connection with one side of the fixing plate 4. Subsequently, the strip block 31 is driven to move into the fixing sleeve 3 by rotating the threaded rod 32 in cooperation with the threaded groove 311, and then the safety net device on one side is tightened toward the other safety net device through the snap connection of the block 314 and the fixing plate 4, thereby making the connection between the two safety net devices tighter and improving the stability of the two safety net devices when spliced.
[0028] like Figure 4 As shown, the utility model provides a technical solution: preferably, the opposing surfaces of the two support plates 2 and the opposing surfaces of the two support plates 5 are provided with a trapezoidal groove 23, the inner wall of the trapezoidal groove 23 is fixedly connected with a damping support rod 25, the output end of the damping support rod 25 is fixedly connected with a trapezoidal block 24, the outer wall of the trapezoidal block 24 is slidably connected to the inner wall of the trapezoidal groove 23, and the outer wall of the output rod of the damping support rod 25 is provided with a spring 26;
[0029] When a falling object falls on the protective net main body 7 connected by the two support plates 25, the weight and impact force of the falling object causes the protective net main body 7 to move downward, and then the downward movement of the protective net main body 7 cooperates with the fixed block 71 to drive the two trapezoidal blocks 24 to approach each other, and squeeze the damping support rod 25 and the spring 1 26. The reverse force of the spring 1 26 buffers the impact force on the protective net main body 7, and the damping property of the damping support rod 25 can prevent the protective net main body 7 from rebounding, thereby preventing the falling objects on the protective net main body 7 from rebounding and falling to cause danger.
[0030] like Figure 5 As shown, the utility model provides a technical solution: preferably, the opposite surfaces of the two trapezoidal blocks 24 are provided with slots 241, the inner wall of the slots 241 is movably connected with a fixed block 71, the opposite surfaces of the two fixed blocks 71 are respectively fixedly connected to the left and right sides of the protective net body 7, and the opposite surfaces of the two fixed blocks 71 are provided with slide grooves 72, the inner wall of the slide groove 72 is fixedly connected with a slide rod 73, the middle part of the outer wall of the slide rod 73 is movably sleeved with a spring three 74, the outer wall of the slide rod 73 away from the spring three 74 The two ends are slidably connected with a slide plate 75, the side of the slide plate 75 away from the spring three 74 is fixedly connected with a plug rod 76, the inner wall of the slot 241 corresponding to the position of the plug rod 76 is provided with a fixed groove 242, and the plug rod 76 passes through the fixed block 71 away from the side of the slide plate 75 to be movably connected in the fixed groove 242;
[0031] By pressing the two slide plates 75, the insertion rods 76 are driven toward each other so that the insertion rods 76 are separated from the fixing grooves 242 and enter the fixing blocks 71. At this time, the protective net body 7 can be removed, thereby facilitating the replacement and maintenance of the damaged protective net body 7.
[0032] Let's talk about the working principle of the anti-fall safety net in detail.
[0033] like Figure 1-5 As shown, when in use, firstly, one safety protection net device is engaged with the other safety protection net device through the cooperation of the T-slot 21 and the T-block 22, thereby ensuring the accuracy of the left and right connection of the safety protection net devices. By splicing the two safety protection nets, the strip block 31 on the left side of one safety protection net device passes through the conical through slot 41 on the side of the fixing plate 4 on the right side of the other safety protection net device, and the block 314 is pushed out of the groove 312 by the thrust of the second spring 313 to form a snap connection with one side of the fixing plate 4, and then the strip block 31 is driven to move into the fixing sleeve 3 by rotating the threaded rod 32 and the threaded groove 311, and then the safety protection net device on one side is tightened toward the other safety protection net device through the snap connection of the block 314 and the fixing plate 4, so that the connection between the two safety protection net devices is more secure. The tightness improves the stability of the two safety protection net devices when they are spliced. When a falling object falls on the protection net main body 7 connected by the two support plates 25, the weight and impact force of the falling object cause the protection net main body 7 to move downward, and then the protection net main body 7 moves downward in cooperation with the fixed block 71 to drive the two trapezoidal blocks 24 to approach each other, and squeeze the damping support rod 25 and the spring 1 26. The reverse force of the spring 1 26 buffers the impact force on the protection net main body 7. At the same time, the damping property of the damping support rod 25 can prevent the protection net main body 7 from rebounding. By pressing the two slide plates 75, the insertion rod 76 is driven to approach each other, so that the insertion rod 76 is separated from the fixing groove 242 and enters the fixing block 71. At this time, the protection net main body 7 can be removed, which is convenient for replacing and maintaining the damaged protection net main body 7.
[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
