Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-6 A temporary construction safety barrier includes: a barrier body 1, a connecting component 2 and an operating component 3 on the barrier body 1, the connecting component 2 including an auxiliary shaft 26 rotatably disposed inside the barrier body 1, a fixing nut 23 fixedly installed on the inner side wall of the barrier body 1, and a threaded hole 22 opened on the barrier body 1, a sliding rod 24 fixedly installed on the side of the auxiliary shaft 26, an auxiliary bolt 21 slidably connected to the sliding rod 24, the auxiliary bolt 21 also being threadedly connected to the fixing nut 23, and a stop block 25 fixedly installed at the end of the sliding rod 24; the stop block 25 is located at the auxiliary bolt Inside 21, the stop block 25 is also slidably connected to the auxiliary bolt 21. The end of the auxiliary bolt 21 is provided with a special-shaped hole that can cooperate with the slide rod 24, and the size of the special-shaped hole is smaller than the size of the stop block 25. The design of the stop block 25 can prevent the auxiliary bolt 21 from coming off, thereby ensuring the stability of the overall structure. In two adjacent guardrail bodies 1, the auxiliary bolt 21 on one guardrail body 1 can be threadedly connected to the threaded hole 22 on the other guardrail body 1, improving the stability of the connection between the two adjacent guardrail bodies 1, thereby improving the protective performance of the overall device.

[0025] The operating component 3 includes a drive shaft 35 rotatably disposed inside the guardrail body 1. A driving worm gear 33 is fixedly mounted on the outer surface of the drive shaft 35 inside the guardrail body 1. The driving worm gear 33 is meshed with a driven worm wheel 34 fixedly connected to an auxiliary shaft 26. A columnar head 31 is fixedly mounted on the upper end of the drive shaft 35, which passes through the guardrail body 1. A T-shaped rod 37 is slidably disposed inside the drive shaft 35. A friction block 36 is fixedly mounted on the lower end of the T-shaped rod 37, and a slider 32 is fixedly mounted on the upper end of the T-shaped rod 37. The slider 32 is also slidably connected to the columnar head 31, and a return spring 38 is provided between the slider 32 and the columnar head 31. The friction block 36 can contact the guardrail body 1 to form a contact surface, and the contact surface is provided with friction texture to enhance friction. The drive shaft 35 is provided with a sliding groove for passing through both ends of the T-shaped rod 37. The two ends of the sliding groove are closed. The column head 31 is provided with a hexagonal socket that can be inserted into a hexagonal wrench. The shape of the slider 32 is consistent with the shape of the hexagonal socket. The upper end of the return spring 38 is fixedly connected to the slider 32, and the lower end of the return spring 38 is fixedly connected to the column head 31. The elastic force of the return spring 38 and the annular friction block 36 cooperate with each other to lock the state of the internal structure and further improve the stability of the overall device.

[0026] The working principle is as follows: When connecting two guardrail bodies 1, the sidewalls of the two guardrail bodies 1 are first brought into contact. Then, a hex wrench is inserted into the cylindrical head 31 to press the slider 32. The T-shaped rod 37 drives the friction block 36 to slide, creating a gap between the friction block 36 and the guardrail body 1. The wrench can then be used to drive the cylindrical head 31 and the transmission shaft 35, which is fixedly connected to the cylindrical head 31, to rotate synchronously inside the guardrail body 1. The driving worm gear 33 on the transmission shaft 35 is also meshed with the driven worm wheel 34, and the driven worm wheel 34 is fixed on the auxiliary shaft 26. At the same time, the driving worm gear 33, the driven worm wheel 34, and the auxiliary shaft 26 are designed as multiple sets of structures. After the transmission shaft 35 rotates, multiple auxiliary shafts 26 can rotate synchronously inside the guardrail body 1. The auxiliary shaft 26 rotates, and the slide rod 24 fixed on the auxiliary shaft 26 is slidably connected to the auxiliary bolt 21. The auxiliary bolt 21 is also threadedly connected to the fixing nut 23 fixed inside the guardrail body 1. Therefore, after the auxiliary shaft 26 rotates, the auxiliary bolt 21 is unscrewed and then screwed into the threaded hole 22 of another guardrail body 1. The two adjacent guardrail bodies 1 are tightly connected through the threaded engagement. Finally, the wrench is pulled out, and under the action of the return spring 38 fixedly connected to the slider 32 and the column head 31 at both ends, the friction block 36 slides upward again, so that the friction texture on the friction block 36 is tightly attached to the guardrail body 1, forming a certain friction force, thereby restricting the rotation of the transmission shaft 35 and other structures, and thus locking the internal structure of the device to lock the state of the auxiliary bolt 21.
