[0003] For example, the Chinese utility model patent (CN220686836U) discloses a protective net for construction safety engineering, which records: "The protective net plate on this device can be folded. When the staff needs to move the protective device, the staff can remove the stress rod from the extension pipe to fold the protective net plate. Moreover, the two load-bearing pipes are connected by a movable connecting rod, and the staff can combine the two load-bearing pipes, thereby reducing the volume of the protective device and facilitating the staff to move the protective device. Also, the protective device has the function of being reused multiple times", and also records: "Nowadays, most of the protective nets used in construction engineering directly fix the protective net to the scaffolding. The protective net has a large volume, which is inconvenient for the staff to move and install, requires a large amount of manpower, and most of them cannot be recycled and reused, resulting in a certain waste" technical problems.

[0028] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] As described in the background art, however, in this device, when the protective net plate is damaged by the device, the protective net needs to be replaced in time to avoid the damaged protective net being difficult to play a good protective role, and this device lacks a structure for facilitating the replacement of the protective net plate.

[0030] To solve this technical problem, the present utility model provides a new type of protective net, which is applied to safety engineering.

[0031] Specifically, please refer to Figures 1 - 2 , the new protective net specifically includes:

[0032] A bearing frame 1, a protective installation mechanism 2 is arranged on the top of the bearing frame 1, and adjusting mechanisms 3 are respectively arranged at the four corners at the bottom of the bearing frame 1;

The outer wall of the bearing frame 1 is closely attached to the protective frame 4, and the inner wall of the protective frame 4 is fixedly connected to the fixed net 5.

[0034] The novel protective net provided by the utility model can move the clamping blocks 9 away from the threaded rods 6 by rotating the two threaded rods 6. As a result, the protective frame 4 and the fixed net 5 can be lifted upward. After placing the new protective frame 4 and the fixed net 5 at a suitable position on the top of the receiving frame 1, rotating the two threaded rods 6 in the reverse direction respectively can make the clamping blocks 9 stuck in the card slots 10. The replacement operation of the protective frame 4 and the fixed net 5 is simple, which is convenient for timely replacement after the fixed net 5 is damaged, ensuring the good protective function of the device and the practicability of the device.

[0035] In order to enable the personnel in the technical field to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings.

[0036] Embodiment 1:

[0037] Please refer to Figures 2 - 4 , a novel protective net, which includes:

[0038] The rotating assembly includes a fixed disk 7. The inner walls of the protective frame 4 are respectively rotatably connected with a fixed disk 7 on the left and right sides. One ends of the two fixed disks 7 located outside the protective frame 4 are respectively fixedly connected with threaded rods 6. The outer walls of the fixed disks 7 are threadedly connected with a plurality of moving blocks 8. The plurality of moving blocks 8 are slidably connected to the inner wall of the protective frame 4. T-shaped strips are respectively fixedly connected to the upper and lower sides of the moving blocks 8. The T-shaped strips are slidably connected to the inner wall of the protective frame 4 to ensure that the moving blocks 8 slide stably inside the protective frame 4.

[0039] The limiting assembly includes clamping blocks 9. The outer walls of the plurality of moving blocks 8 are respectively fixedly connected with clamping blocks 9. The plurality of clamping blocks 9 are respectively slidably connected to the inner wall of the protective frame 4. The protective frame 4 plays a supporting role for the fixed net 5. When the fixed net 5 is damaged due to the falling of heavy objects, the protective frame 4 can be disassembled. Subsequently, the fixed net 5 can be cut from the protective frame 4, and then a new fixed net 5 can be welded on for reuse. The protective frame 4 provides protection for the internal fixed disk 7, moving blocks 8 and clamping blocks 9. Card slots 10 adapted to the clamping blocks 9 are provided at the top of the receiving frame 1.

[0040] Through the above structural design, rotating the two threaded rods 6 will drive the corresponding fixed disks 7 to rotate accordingly. As a result, the moving blocks 8 on the fixed disks 7 will move away from the threaded rods 6 under the restriction of the protection frame 4, that is, the clamping blocks 9 will move away from the threaded rods 6. Thus, the clamping blocks 9 will move to directly below the top opening inside the card slots 10. Then, the protection frame 4 and the fixed net 5 can be lifted upward. After placing the new protection frame 4 and the fixed net 5 at the appropriate positions on the top of the receiving rack 1, the new clamping blocks 9 are located in the corresponding card slots 10. Subsequently, rotating the two threaded rods 6 in the reverse direction respectively will drive the moving blocks 8 and the clamping blocks 9 to move towards the positions where the threaded rods 6 are located under the restriction of the protection frame 4, and the clamping blocks 9 can be made to be stuck in the card slots 10.

[0041] Embodiment 2:

[0042] The new protection net provided in Embodiment 1 is further optimized. Specifically, as Figures 5 - 6 shown, the adjusting mechanism 3 includes a lifting rack 11, a support sleeve housing 12, a fixed housing 13, a transmission component, and a blocking component. The bottom of the receiving rack 1 is detachably connected with the lifting rack 11 through bolts. The outer wall of the lifting rack 11 is slidably connected with the support sleeve housing 12, and the inner wall of the support sleeve housing 12 is fixedly connected with the fixed housing 13.

[0043] The transmission component includes a rotating shaft 14. The inner wall of the fixed housing 13 is rotatably connected with the rotating shaft 14. The outer wall of the rotating shaft 14 is fixedly connected with a gear 15. The gear 15 is engaged with the outer wall of the lifting rack 11. The outer wall of the rotating shaft 14 is fixedly connected with a ratchet 16. It can be seen that during the process of the lifting rack 11 sliding out of the support sleeve housing 12, the rotating shaft 14 will be driven to rotate by the gear 15, and then the ratchet 16 will be driven to rotate accordingly.

[0044] The blocking component includes a support frame 17. The inner wall of the fixed housing 13 is fixedly connected with the support frame 17. The inner wall of the support frame 17 is rotatably connected with a rotating rod 18. The rotating rod 18 is rotatably connected with the inner wall of the fixed housing 13. The outer wall of the rotating rod 18 is fixedly connected with a pawl 19 adapted to the ratchet 16. On the outside of the rotating rod 18 and on both sides of the pawl 19, torsion springs 20 are respectively sleeved. The two ends of the torsion springs 20 are respectively fixedly connected with the outer walls of the support frame 17 and the pawl 19. The torsion springs 20 make the pawl 19 always tend to closely adhere to the ratchet 16.

[0045] After the support housing 12 is placed in position through the above structural design, pulling the lifting rack 11 upward can cause the lifting rack 11 to slide inside the support housing 12, thereby increasing the height of the receiving frame 1. During this process, the lifting rack 11 drives the rotating shaft 14 to rotate through the gear 15, and then drives the ratchet wheel 16 to rotate accordingly. The pawl 19 is pressed against the outer wall of the ratchet wheel 16 under the elastic force of the torsion spring 20. Then, after the receiving frame 1 is raised to an appropriate position, the lifting rack 11 is released. The pawl 19 immediately restricts the ratchet wheel 16 from rotating in the reverse direction, thereby preventing the gear 15 from rotating in the reverse direction through the rotating shaft 14, and further preventing the lifting rack 11 from descending, so that the receiving frame 1 can be maintained at the adjusted height. Subsequently, when it is necessary to lower the height of the receiving frame 1, rotating the rotating rod 18 can cause the pawl 19 to leave the ratchet wheel 16, and at the same time, the torsion spring 20 deforms accordingly. Then, under the gravitational action of the receiving frame 1, the protective installation mechanism 2 and the lifting rack 11, the lifting rack 11 can be lowered, and then the rotating shaft 14 can be reversed through the gear 15 to complete the adjustment of the position of the receiving frame 1 downward.
