Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] like Figures 1 to 6 As shown, the utility model provides a high-strength flame-retardant safety net, comprising:
[0032] A first cylinder 1, a net body 2 is movably sleeved on the inner surface of the right end of the first cylinder 1, and a second cylinder 3 is fixedly sleeved on the right end of the net body 2;
[0033] An adjusting mechanism 4, the adjusting mechanism 4 is arranged at the top end of the first cylinder 1;

[0035] Among them, the adjusting mechanism 4 includes a winding rod 401, which is movably sleeved on the inner surface of the first cylinder 1, and the right end of the winding rod 401 is fixedly connected to the left end of the net body 2. The bottom end of the winding rod 401 is movably installed with a lower end cover 402, and the top of the lower end cover 402 is fixedly connected to the bottom end of the first cylinder 1. The lower end cover 402 is movably sleeved with an extension rod 403 inside, and the top of the extension rod 403 is fixedly connected to the bottom end of the winding rod 401. A rotating ring 404 is fixedly installed on the bottom end of the extension rod 403. A slot 405 is provided on the inner surface of the lower end cover 402, and a block 406 is movably sleeved inside the slot 405. The bottom end of the block 406 penetrates the extension rod 403 and extends to the inside of the extension rod 403 and is fixedly installed with a rectangular block 407. The rectangular block 407 is movably sleeved on the right side of the top end inside the extension rod 403. Rotating the ring 404 will cause the winding rod 401 to rotate.
[0036] When the rectangular block 407 moves downward along the inner surface of the extension rod 403 with the card block 406, the card block 406 and the card slot 405 will be separated, thereby releasing the lock of the card block 406 on the extension rod 403. At this time, rotating the rotating ring 404 will cause the rotating ring 404 to rotate along the inner surface of the lower end cover 402 with the extension rod 403, so that the winding rod 401 fixedly connected to the extension rod 403 will rotate along the inner surface of the first cylinder 1 with the net body 2, so that the tightness of the net body 2 can be adjusted, thereby improving the convenience of installing the flame retardant safety net.
[0037] Wherein, the pulling mechanism 5 includes:

[0041] When the stretching ring 505 is pulled, the round rod 503 will move leftward along the inner surface of the extension rod 403 with the movable block 502 and compress the first spring 504. At this time, the connecting rod 501 will generate a pulling force on the rectangular block 407, pulling the rectangular block 407 to move downward.
[0042] The left inner wall of the extension rod 403 is provided with a limiting groove 6 , the top of the limiting groove 6 is movably sleeved with a limiting block 7 , and the right end of the limiting block 7 is fixedly connected to the left end of the rectangular block 407 .
[0043] The cooperation between the limiting groove 6 and the limiting block 7 will limit the movement of the rectangular block 407 .
[0044] Among them, the right end of the first cylinder 1 is fixedly installed with an upper end cover 8, the interior of the upper end cover 8 is fixedly sleeved with a first fixing rod 9, the left end of the first fixing rod 9 is movably connected to the right end of the winding rod 401, and the right end of the first fixing rod 9 is fixedly installed with a first ring 10.
[0045] The cooperation between the upper end cover 8 and the lower end cover 402 will ensure the stability of the rotation of the winding rod 401 and prevent the winding rod 401 from being separated from the first cylinder 1.
[0046] Among them, the second fixing rod 12 is fixedly installed at the upper and lower ends of the second cylinder 3, and the second ring 13 is fixedly installed at the top of the second fixing rod 12. The outer surface of the second fixing rod 12 is movably sleeved with a round block 11. There are two round blocks 11, and the opposite surfaces of the two round blocks 11 are movably connected to the upper and lower ends of the second cylinder 3 respectively.
[0047] The inner surface of the round block 11 and the outer surface of the second fixing rod 12 are both smooth, ensuring that the round block 11 will not get stuck when rotating along the outer surface of the second fixing rod 12 .
[0048] Among them, the left ends of the two round blocks 11 are respectively fixedly installed with connecting blocks 14, the left end of the connecting block 14 is fixedly installed with a clamping sleeve 15, the right side of the front top of the clamping sleeve 15 is fixedly installed with a stopper 18, the right side of the front top of the clamping sleeve 15 is fixedly installed with a round shaft 16, the outer surface of the round shaft 16 is movably sleeved with a short rod 17, the bottom end of the short rod 17 is movably connected to the top of the clamping sleeve 15, the right side of the front end of the short rod 17 is movably connected to the rear end of the stopper 18, and the short rod 17 will rotate.
[0049] When the short rod 17 is squeezed, it will rotate along the top of the sleeve 15 with the circular shaft 16 as the axis. At the same time, the size of the sleeve 15 is larger than the size of the first fixed rod 9 and the extension rod 403, thereby ensuring that the first fixed rod 9 and the extension rod 403 will not affect the rotation of the short rod 17 after being respectively inserted into the interior of the sleeve 15 on the upper and lower sides of the second cylinder 3.
[0050] The rear end of the short rod 17 is fixedly mounted with a second spring 19 , the other end of the second spring 19 is fixedly mounted with a long rod 20 , and the bottom end of the long rod 20 is fixedly connected to the top end of the connecting block 14 .
[0051] When the short rod 17 rotates, the second spring 19 will be compressed, and under the restoring action of the second spring 19, the short rod 17 will be forced to return to its original position.
[0052] The working principle and use process of this utility model:
[0053] First, the operator fixes one end of the safety net through the second rings 13 at the upper and lower ends of the second cylinder 3, and then pulls the stretching ring 505, so that the stretching ring 505 moves along the inner surface of the extension rod 403 with the movable block 502 through the round rod 503 and compresses the first spring 504. At this time, the connecting rod 501 hinged to the movable block 502 will move together, so that the other end of the connecting rod 501 generates a pulling force on the rectangular block 407, pulling the rectangular block 407 and moving the clamping block 406 downward along the inner surface of the clamping slot 405 until the clamping block 406 and the clamping slot 405 are separated. Then the operator can rotate the rotating ring 40 4, so that the rotating ring 404 rotates along the inner surface of the first cylinder 1 with the winding rod 401 and the net body 2 through the extension rod 403, thereby winding the net body 2 until the tightness of the net body 2 is appropriate, and then the stretching ring 505 is loosened. Under the recovery effect of the first spring 504, the clamping block 406 will be re-embedded in the clamping groove 405, thereby locking the positions of the extension rod 403, the rotating ring 404 and the winding rod 401, and finally the safety net is fixed by the rotating ring 404 and the first ring 10. The mutual cooperation of various mechanisms makes it more convenient to adjust the tightness of the safety net and ensures that the four corners of the safety net are evenly stressed.
[0054] When the safety net is used up, the second cylinder 3 is rotated toward the first cylinder 1 to roll up the net body 2, and then the operator rotates the round blocks 11 at the upper and lower ends of the second cylinder 3 respectively, so that the round blocks 11 rotate along the outer surface of the second fixed rod 12 with the connecting block 14 and the clamping sleeve 15. When the short rods 17 on both sides of the second cylinder 3 contact the extension rod 403 and the first fixed rod 9 respectively, the short rods 17 will be squeezed, so that the short rods 17 rotate around the circular shaft 16 as the axis and compress the second spring 19 until the extension rod 403 and the first fixed rod 9 are completely inserted into the interior of the clamping sleeves 15 on the upper and lower sides of the second cylinder 3 respectively. At this time, under the restoring action of the second spring 19, the short rods 17 will return to their original position and fit with the stopper 18, so that the first cylinder 1 and the second cylinder 3 can be fixed, thereby preventing the safety net from spreading.
[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
