[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1-5 shown, the present utility model provides a safety net for construction engineering, including a safety net main body 1. Square sleeves 2 are fixedly connected to both the left and right ends of the safety net main body 1. The two square sleeves 2 are respectively clamped with the relatively close sides of the two installation support components 3. Through the mutual cooperation between the provided square sleeves 2 and the installation support components 3, the installation and fixation process of the safety net main body 1 can be quickly realized. And when the safety net main body 1 is damaged during use, it can be conveniently removed from the device, and then it is convenient to replace it, so that the installation and disassembly process of the device for the safety net main body 1 becomes more convenient, effectively solving the problem that the existing safety nets are relatively inconvenient to install and disassemble during use. Two fixing plates 6 are fixedly connected to the outer end of one of the installation support components 3, and two T-shaped sleeves 7 are fixedly connected to the outer end of the other installation support component 3. A reflective strip 8 is adhesively bonded to the edge of the surface of the safety net main body 1. By pasting the reflective strip 8 on the safety net main body 1, the safety net main body 1 can have a reflective effect, improving the warning effect of the safety net main body 1. Subsequently, the two fixing plates 6 are respectively movably connected to the two pins 4 through the circular holes opened in their interiors. The two pins 4 are respectively adapted to the two T-shaped sleeves 7. Springs 5 are sleeved on the two pins 4. Through the mutual cooperation between the provided fixing plates 6, T-shaped sleeves 7, springs 5 and pins 4, multiple such devices can be connected together according to different protection ranges during the use of the device, so that the device can adapt to different construction sites, expanding the applicable range of the device.

[0026] The two installation support components 3 both include concave frames 33. The outer end of one concave frame 33 is fixedly connected to the surface of the fixed plate 6, and the outer end of the other concave frame 33 is fixedly connected to the surface of the T-shaped sleeve 7. Both concave frames 33 are respectively movably connected to the upper smooth rod parts of the two threaded rods 313 through the connection holes opened inside their upper ends. A lighting lamp 9 is installed at the top of the concave frame 33, and the lighting lamp 9 is arranged at the outer end of the threaded rod 313. Through the installed lighting lamp 9, lighting can be provided for the surrounding area of the protection net main body 1 in the night environment. Threaded on the two threaded rods 313 are T-shaped plates 311. Two by two of the four T-shaped plates 311 are in a group, and their relatively close ends are fixedly connected with square insertion rods 312. Two by two of the four square insertion rods 312 are respectively clamped with the two square sleeves 2. Two by two of the four T-shaped plates 311 are respectively movably connected to the two limiting vertical rods 314 through the limiting holes opened inside them. The upper and lower ends of the two limiting vertical rods 314 are respectively fixedly connected to the upper and lower side surfaces inside the two concave frames 33. The relatively far ends of the upper two T-shaped plates 311 are fixedly connected with toothed plates 310. When the device is no longer in use or the protection net main body 1 is damaged during use and needs to be removed from the device, by rotating the two threaded rods 313, the corresponding two T-shaped plates 311 can be driven to move away from each other to a certain distance. Then, by pulling up the protection net main body 1, the two square sleeves 2 are no longer clamped with the four square insertion rods 312. At this time, the protection net main body 1 can be conveniently removed from the device, thus achieving the disassembly process of the protection net main body 1. During the process of driving the upper two T-shaped plates 311 to move upward, the two toothed plates 310 can be driven to move accordingly. Through the arranged limiting vertical rods 314, the movement direction of the T-shaped plates 311 can be restricted.

[0027] The toothed plate 310 is in meshing transmission with the gear 39, and the gear 39 is fixedly connected to the middle position of the worm 37. The worm 37 is in meshing transmission with the worm gear 34, and the worm gear 34 is fixedly connected to the rotating rod 36. The four rotating rods 36 are grouped in pairs, and connecting plates 32 are fixedly connected to their relatively close ends. The lower ends of the four connecting plates 32 are all fixedly connected to the bottom plate 31. The bottom of the bottom plate 31 is serrated, which can make the bottom plate 31 grip the ground more stably. Support plates 35 are movably connected to the four rotating rods 36. The four support plates 35 are grouped in pairs, and their lower ends are respectively fixedly connected to the inner bottom surfaces of the two concave frames 33. The front and rear ends of the two worms 37 are movably connected to L-shaped plates 38. The four L-shaped plates 38 are grouped in pairs, and their relatively close ends are respectively fixedly connected to the front and rear sides of the two concave frames 33. The lower ends of the two threaded rods 313 are respectively movably connected to the inner bottom surfaces of the two concave frames 33. In the process of driving the two toothed plates 310 to move upward, the two worms 37 can be driven to rotate under the action of the two gears 39 provided. The two worms 37 are respectively in meshing transmission with the four worm gears 34, so as to drive the four rotating rods 36 to rotate. The rotation directions of the corresponding two rotating rods 36 are opposite. Through the rotation of the four rotating rods 36, the four bottom plates 31 can be driven to rotate upward by 90 degrees around the four corresponding rotating rods 36 under the action of the four connecting plates 32 provided. At this time, the storage process of the four bottom plates 31 can be realized, reducing the occupied space of the device and facilitating the carrying and transportation of the device. The L-shaped plates 38 provided can support the worm 37, the support plates 35 provided can support the rotating rod 36, and the mutual cooperation between the bottom plate 31 and the concave frame 33 provided can increase the stability of the device during use.

[0028] The operation steps of the present utility model are as follows:

[0029] When protecting a construction site, according to the different areas to be protected, multiple such devices are connected through the mutual cooperation among the set pin 4, spring 5, fixing plate 6 and T-shaped sleeve 7, so as to achieve the protection effect on the construction site. When the device is no longer in use or the protection net main body 1 is damaged, by rotating the two threaded rods 313, the two corresponding T-shaped plates 311 can be driven to move away from each other. When the two corresponding T-shaped plates 311 move away from each other to a certain distance, the two upper square insertion rods 312 are respectively removed from the interiors of the two corresponding square sleeves 2. Then, by pulling up the protection net main body 1, the two square sleeves 2 are driven to move upward, so that the two square sleeves 2 are no longer clamped with the two lower square insertion rods 312. At this time, the effect of removing the protection net main body 1 from the device can be achieved. During the process of removing the protection net main body 1 from the device, the upward movement of the two upper T-shaped plates 311 can drive the two worms 37 to rotate under the action of the set toothed plate 310 and gear 39. The two worms 37 are meshed and driven with the four worm wheels 34, and then the four rotating rods 36 can be driven to rotate. Through the rotation of the four rotating rods 36, under the action of the set connecting plate 32, the four bottom plates 31 can be driven to rotate upward by 90 degrees around the four corresponding rotating rods 36 respectively. At this time, the process of storing the four bottom plates 31 can be achieved.

The scope of the present invention is defined by the appended claims and their equivalents.
