Detailed Description of the Embodiment

[0022] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: a column-shaped protective net for building construction, including a column-shaped outer shell 1. One end of the column-shaped outer shell 1 is provided with a notch, and the other end is provided with a clamping groove 2. The bottom end of the column-shaped outer shell 1 is fixedly connected with an adjusting mechanism 3 for adjusting the height of the protective net. The bottom end of the adjusting mechanism 3 is provided with a base 4. A winding roller 5 is arranged in the inner cavity of the column-shaped outer shell 1. The winding roller 5 is rotationally connected with the inner cavity of the column-shaped outer shell 1 through a rotating shaft. The top end of the winding roller 5 is provided with a rotating structure 6 for rotation. A net body 7 is wound around the outer surface of the winding roller 5. The other end of the net body 7 penetrates through the column-shaped outer shell 1 and is fixedly connected with a clamping seat 8. The clamping seat 8 is in interference fit with the inner cavity of the clamping groove 2;

[0024] During disassembly, moving the clamping seat 8 out of the inner cavity of the clamping groove 2 can complete the disassembly between the two columns and the protective net, facilitating the disassembly between the columns and the protective net. During assembly, when the clamping seat 8 is inserted into the clamping groove 2, the two columns and the protective net can be combined. Through the cooperation of the rotating structure 6 and the winding roller 5, the net body 7 can be wound up, reducing the volume of the protective net, thereby reducing the occupied space of the column-shaped protective net and providing convenience for the transfer and transportation of the column-shaped protective net by construction workers.

[0025] The adjusting mechanism 3 includes a support column 31 and a square tube 32. The support column 31 is inserted and slid in the inner cavity of the square tube 32. The top end of the support column 31 is fixedly connected with the bottom end of the column-shaped outer shell 1. The bottom end of the square tube 32 is fixedly connected with the top end of the base 4. A positioning structure for positioning the position of the support column 31 is arranged on the outer side wall of the square tube 32. Pulling the column-shaped outer shell 1 drives the support column 31 to slide in the inner cavity of the square tube 32. After adjusting the position of the support column 31 in the inner cavity of the square tube 32, it is positioned through the positioning structure to realize the adjustment of the height of the column-shaped protective net.

[0026] The positioning structure includes a support frame 33. The support frame 33 is fixedly connected to the outer side wall of the square tube 32. Through holes are formed on the surface of the support frame 33. A movable rod 34 is inserted and slid in the inner cavity of the through hole of the support frame 33. One end of the movable rod 34 is fixedly connected with a limit block 35, and the other end is fixedly connected with a fixed block 36. Fixed grooves 37 are formed on the surface of the support column 31. The fixed block 36 is in interference fit with the inner cavity of the fixed groove 37. Pulling the limit block 35 drives the fixed block 36 to move through the movable rod 34. When the fixed block 36 is inserted into the inner cavity of the fixed groove 37, the position of the support column 31 in the square tube 32 is positioned. When the fixed block 36 is moved out of the inner cavity of the fixed groove 37, the position of the support column 31 in the square tube 32 can be adjusted.

[0027] A spring 9 is sleeved on the outer surface of the movable rod 34. The spring 9 is located between the support frame 33 and the fixed block 36. The bottom end of the fixed block 36 is provided with an inclined cut surface. Through the cooperation of the spring 9 and the fixed block 36, when the construction worker pulls the support column 31 upward, the fixed groove 37 squeezes the fixed block 36, causing the fixed block 36 to move towards the support frame 33 and squeeze the spring 9. When the fixed block 36 moves into the inner cavity of another set of fixed grooves 37, the spring 9 is released to push the fixed block 36 to be engaged with the fixed groove 37.

[0028] A reinforcing block 10 is fixedly connected to the bottom end of the square tube 32. The bottom end of the reinforcing block 10 is fixedly connected to the top end of the base 4. The shape of the reinforcing block 10 is triangular. Through the arrangement of the reinforcing block 10, the connection between the square tube 32 and the base 4 is strengthened, avoiding the phenomenon that the position of the square tube 32 becomes loose after long-term use.

[0029] The rotating structure 6 includes a rotating handle 61. The rotating handle 61 is located at the top end of the cylindrical housing 1. The bottom end of the rotating handle 61 is fixedly connected to a connecting rod 62. The bottom end of the connecting rod 62 penetrates through the cylindrical housing 1 and is fixedly connected to the winding roller 5. Shaking the rotating handle 61 drives the winding roller 5 to rotate through the connecting rod 62, so that the winding roller 5 winds the net body 7, thus facilitating the winding work of the protective net.

[0030] A movable sleeve 11 is inserted and fixed on the surface of the cylindrical housing 1. A positioning pin 12 is inserted and slid in the inner cavity of the movable sleeve 11. A positioning hole 13 is formed on the upper surface of the winding roller 5. The positioning pin 12 is engaged with the inner cavity of the positioning hole 13. When the inner cavity of the positioning pin 12 moves into the inner cavity of the positioning hole 13, the position of the winding roller 5 after rotation can be positioned. When the positioning pin 12 is pulled out of the inner cavity of the movable sleeve 11, the winding roller 5 is released, and the net body 7 can be wound or unwound.

[0031] During specific use: The construction workers pull the clamping seat 8 at one end to drive the net body 7 to move. The net body 7 drives the winding roller 5 to rotate to unwind the net body 7. Then, the clamping seat 8 is inserted into the inner cavity of the card slot 2 to combine the two groups of columns. Subsequently, the positioning pin 12 is inserted into the inner cavity of the movable sleeve 11. When the bottom end of the positioning pin 12 moves into the positioning hole 13, the position of the winding roller 5 is positioned, completing the combination work of the cylindrical protective net. During disassembly, the clamping seat 8 is removed from the inner cavity of the card slot 2. Then, the crank 61 is shaken to drive the winding roller 5 to rotate through the connecting rod 62 to wind the net body 7, realizing the disassembly work between the two groups of columns and the net body 7. When adjusting the height, the support column 31 is pulled upward. The support column 31 drives the fixed groove 37 to move upward to squeeze the fixed block 36, causing the fixed block 36 to move towards the support frame 33 to squeeze the spring 9. When the fixed block 36 moves into the inner cavity of another fixed groove 37, the spring 9 is released to push the fixed block 36 to cooperate and engage with the fixed groove 37. By adjusting the position of the fixed block 36 in the fixed groove 37, the adjustment of the height of the protective net is realized. Pulling the limit block 35 drives the fixed block 36 to move out of the inner cavity of the fixed groove 37 through the movable rod 34, and the support column 31 can be released, and the support column 31 can be contracted, thereby reducing the occupied space of the cylindrical protective net, providing convenience for the construction workers to transfer and transport the cylindrical protective net.
