[0016] Beneficial effects of the utility model:

[0017] 1. An adjustable anti-fall safety net bag. When the service life of the protective net bag on the safety net bag is reached, the quick disassembly and assembly assembly can be used to quickly complete the disassembly of the protective net bag. When disassembly is required, the sliding frame is pushed to move it upward, so that the ball engaged in the rectangular groove also moves upward. Since the lower end of the inner wall of the locking sleeve is an inclined structure, the ball has a larger movement space when moving upward and does not contact the insertion rod. At this time, the insertion rod is slid out and replaced with a new protective net bag, and the insertion rod is reinserted. If the sliding frame is not pushed to move upward, the ball will contact the outer wall of the insertion rod and lock the insertion rod due to the internal inclination of the locking sleeve and the spring seat, so that the insertion rod will not slip. Through this structural design, there is no need to replace the connecting mechanism on the protective net bag, thereby reducing the time and cost required for replacement and improving work progress.

[0018] 2. An adjustable anti-fall safety net bag. When the safety net bag is in use, a rope pulling and locking assembly is provided on the draw rope. The rope pulling and locking assembly can quickly complete the adjustment and locking work of the extension and retraction length of the draw rope. When the length of the draw rope needs to be adjusted, the locking sleeve is rotated to cancel the threaded connection between the locking sleeve and the paddle. When the draw rope is pulled, the draw rope inside the rope storage tube slides out. After adjusting the appropriate length, the locking sleeve is rotated to make it threadedly connected with the paddle. Since the paddle is an elastic inclined structure and the inner diameter of the locking sleeve is smaller than the outer diameter of the thread on the paddle, the paddle is squeezed inwardly during connection to complete the locking work of the draw rope. The more the locking sleeve is rotated, the greater the inward contraction distance of the paddle is, and the greater the locking force is. The convenience of adjusting the draw rope distance is greatly improved through this structural design. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figures 1 to 5As shown, an adjustable anti-fall safety net bag comprises a protective net bag 1, and quick disassembly and assembly components 2 are arranged at the four corners of the protective net bag 1, and the quick disassembly and assembly component 2 comprises an L-shaped mounting block 201, and a pull rope 304 is arranged at one end of the L-shaped mounting block 201, and the lower end of the pull rope 304 is sleeved on the L-shaped mounting block 201, and the quick disassembly and assembly component 2 is used for quick installation and removal between the protective net bag 1 and the L-shaped mounting block 201; a rope pulling and locking component 3 is arranged at the upper end of the pull rope 304, and the rope pulling and locking component 3 comprises a rope storage cylinder 301, and the upper end of the pull rope 304 is fixedly connected to the rope storage cylinder 301 Inside, the rope pulling and locking assembly 3 is used to quickly adjust and lock the length of the pull rope 304. When the service life of the protective net bag 1 is reached, the quick disassembly and assembly assembly 2 can be used to quickly complete the disassembly of the protective net bag 1, and there is no need to replace the connecting mechanism on the protective net bag 1, thereby reducing the time and cost required for replacement and improving work progress. In addition, a rope pulling and locking assembly 3 is provided on the pull rope 304. The rope pulling and locking assembly 3 can be used to quickly complete the adjustment and locking of the telescopic length of the pull rope 304, which greatly improves the convenience of adjusting the distance of the pull rope 304.

[0030] Further, such as Figure 1 , Figure 3 , Figure 4As shown, an opening is provided at the corner of the L-shaped mounting block 201, and the lower end of the pull rope 304 is sleeved with the L-shaped mounting block 201 through the opening. Both ends of the L-shaped mounting block 201 are fixedly connected with a lock sleeve 202, and the inner top of the lock sleeve 202 is fixedly connected with a telescopic spring seat 203. The lower end of the inner wall of the lock sleeve 202 is inclined and evenly spaced with three rectangular grooves 207. The inner lower end of the lock sleeve 202 is provided with three spheres 204 and respectively engaged with the three rectangular grooves 207. The lower end of the telescopic spring seat 203 contacts the three spheres 204. The inside of the lock sleeve 202 is slidably connected with a plug rod 206, and the lower end of the lock sleeve 202 is slidably connected with a sliding frame 205. The upper end of the sliding frame 205 is engaged and connected to the lower end of the inner wall of the lock sleeve 202. When the service life of the protective net bag 1 is reached, it can be quickly completed by providing a quick disassembly component 2 To disassemble the protective net bag 1, when it is necessary to disassemble, push the sliding frame 205 to move it upward, so that the ball 204 engaged in the rectangular groove 207 also moves upward. Since the lower end of the inner wall of the locking sleeve 202 is an inclined structure, the ball 204 has a larger movement space when moving upward and does not contact the insertion rod 206. At this time, the insertion rod 206 is slid out and replaced with a new protective net bag 1, and the insertion rod 206 is reinserted. If the sliding frame 205 is not pushed to move upward, the ball 204 will contact and lock the outer wall of the insertion rod 206 due to the internal inclination of the locking sleeve 202 and the telescopic spring seat 203, so that the insertion rod 206 will not slip. Through this structural design, there is no need to replace the connecting mechanism on the protective net bag 1, thereby reducing the time and cost required for replacement and improving work progress.

[0031] Further, such as Figure 2As shown, a plurality of paddles 302 are evenly spaced and fixedly connected to the middle of one end surface of the rope storage tube 301. The paddle 302 is an elastic inclined surface structure and is provided with a thread on its outer wall. The outer wall of the paddle 302 is threadedly connected with a locking sleeve 303. The inner diameter of the locking sleeve 303 is smaller than the outer diameter of the thread on the paddle 302. When the safety net bag is in use, a rope drawing and locking assembly 3 is provided on the draw rope 304. The rope drawing and locking assembly 3 can quickly complete the adjustment and locking of the telescopic length of the draw rope 304. When the length of the draw rope 304 needs to be adjusted, the locking sleeve 303 is canceled by rotating the locking sleeve 303. The threaded connection between the paddle 302 and the pull rope 304 is pulled to make the pull rope 304 inside the rope storage tube 301 slide out. After adjusting the appropriate length, the locking sleeve 303 is rotated to make it threadedly connected with the paddle 302. Since the paddle 302 is an elastic inclined surface structure and the inner diameter of the locking sleeve 303 is smaller than the outer diameter of the thread on the paddle 302, the paddle 302 is squeezed inwardly during connection to complete the locking of the pull rope 304. The more the locking sleeve 303 is rotated, the greater the inward contraction distance of the paddle 302 and the greater the locking force. This structural design greatly improves the convenience of adjusting the distance of the pull rope 304.

[0032] Further, such as Figure 1 , Figure 5 As shown, a buffer spring 5 is fixedly connected to one end face of the rope storage tube 301, and one end of the buffer spring 5 is fixedly connected to an angle adapter bracket 4. A bolt installation and fixing assembly is provided at the upper end of the angle adapter bracket 4. The protective net bag 1 is made of polypropylene material. The buffer spring 5 and the angle adapter bracket 4 can better provide a buffer for objects falling on the protective net bag 1. The installation and fixing work of the safety net bag is completed by the bolt installation and fixing assembly. The protective net bag 1 made of polypropylene material can withstand a large weight and withstand the test of various harsh environments, thereby increasing the service life of the safety net bag.
