[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 like Figures 1-7As shown, this utility model provides a technical solution: a self-locking construction safety net, including a support column 1 and a protective net 2. The support column 1 has connecting grooves 101 on both sides, a positioning groove 102 on its surface, and a cavity 103 inside. T-shaped blocks 21 are fixedly installed on both sides of the protective net 2. A handle 3 is provided on the surface of the support column 1, and a connecting rod 4 is rotatably installed on its surface. A sleeve 31 is fixedly connected to the rear end of the handle 3, and the sleeve 31 is slidably fitted onto the surface of the connecting rod 4. A bidirectional lead screw 5 is rotatably installed inside the cavity 103, and a hollow seat 6 is slidably installed inside the cavity 103. A locking block 6 is slidably installed on the side of the hollow seat 6. 1. The hollow seat 6 has a spring 62 fixedly connected to the locking block 61 inside. The shape of the T-shaped block 21 matches the shape of the docking groove 101. The side of the T-shaped block 21 has a locking groove 211. One end of the locking block 61 abuts against the inside of the locking groove 211. The surface of the bidirectional lead screw 5 is fixedly connected to the rear end of the connecting rod 4. The surface of the bidirectional lead screw 5 is threaded with a threaded sleeve block 51. The side of the threaded sleeve block 51 is rotatably mounted with a rotating rod 52. The other end of the rotating rod 52 is rotatably connected to the outer wall of the hollow seat 6. The cavity 103 has a slide rod 11 fixedly installed inside. The front and rear ends of the hollow seat 6 are both fixedly mounted with guide plates 63. One guide plate 63 is slidably mounted on the surface of the slide rod 11.

[0019] In this embodiment, the T-shaped block 21 installed on the side of the protective net 2 is adapted to the shape of the mating groove 101 opened on the side of the support column 1. The T-shaped block 21 slides downward and inserts into the mating groove 101, which facilitates the connection and combination of the protective net 2 and the support column 1. One end of the locking block 61 is set in the locking groove 211, and the other end of the locking block 61 is connected to the spring 62, so that the locking block 61 can be reset after being squeezed and moved. The locking block 61 can limit the T-shaped block 21 by embedding in the locking groove 211, so that the connection and fixation between the protective net 2 and the support column 1 are fixed. The threaded sleeve 51 is... The thread is installed on the surface of the double-acting lead screw 5. Rotating the handle 3 drives the connecting rod 4 and the double-acting lead screw 5 to rotate, which allows the threaded sleeve block 51 to move and adjust the position and angle of the rotating rod 52. The hollow seat 6 moves into the cavity 103, which allows the locking block 61 to be moved out of the slot 211. The guide plate 63 moves on the surface of the slide rod 11, which can improve the stability of the hollow seat 6 when it moves. Releasing the fixing of the T-block 21 allows the protective net 2 to be lifted upwards and separated from the support column 1. The protective net 2 can be disassembled and maintained separately without disassembling the support column 1, thereby improving maintenance efficiency.

[0020] Example 2 like Figures 1-7As shown, the connecting rod 4 has a sliding groove 401 inside, a slider 41 is slidably installed inside the sliding groove 401, a spring 42 is fixedly connected to the slider 41 inside the sliding groove 401, there are several positioning grooves 102, a limit block 32 is fixedly connected to the rear end of the sleeve 31, the limit block 32 is abutted inside the positioning groove 102, a connecting block 33 is fixedly installed inside the sleeve 31, and the bottom of the connecting block 33 is fixedly connected to the top of the slider 41.

[0021] In this embodiment, the spring 42 supports the slider 41, and the connecting block 33 is connected to the slider 41. The limiting block 32 is abutted inside the positioning groove 102 to limit the rotation of the handle 3 and the connecting rod 4, preventing them from rotating. The fixed bidirectional screw 5 ensures the stability of the locking block 61 during use, thereby ensuring a stable connection between the protective net 2 and the support column 1. The sleeve 31 can slide on the surface of the connecting rod 4. Pulling the handle 3 outward can move the limiting block 32 at the rear end of the sleeve 31 out of the positioning groove 102, releasing the limitation on the handle 3 and the connecting rod 4, allowing the bidirectional screw 5 to rotate.

[0022] Working principle: By pre-installing and fixing the support column 1, the T-shaped block 21 on the side of the protective net 2 is then inserted into its docking groove 101. The protective net 2 is installed between the two support columns 1. When the T-shaped block 21 moves down inside the docking groove 101, it presses against the locking block 61. The locking block 61 moves towards one end of the second spring 62. When the position of the locking groove 211 aligns with the position of the locking block 61, the second spring 62 rebounds, causing the locking block 61 to embed into the locking groove 211, thus achieving self-locking installation of the protective net 2. When the protective net 2 needs to be disassembled and replaced, the limiting block 32 is moved out of the positioning groove 102 by pulling the handle 3 outward. At this time, rotating the handle 3 drives the... The connecting rod 4 and the double-acting screw 5 rotate, and the threaded sleeve 51 on the surface of the double-acting screw 5 moves to adjust the position and angle of the rotating rod 52. The rotating rod 52 pulls the hollow seat 6 into the cavity 103, thereby removing the locking block 61 from the slot 211. Then, the protective net 2 is lifted up to separate it from the support column 1. A new protective net 2 is replaced and reinstalled. The handle 3 is turned back to reset the hollow seat 6 and the locking block 61 and fix the T-shaped block 21 on the side of the protective net 2. When the handle is released, the spring 42 rebounds and the limiting block 32 is re-embedded into the positioning slot 102. The locking block 61 is fixed, thereby making the protective net 2 and the support column 1 stably connected.
