DETAILED DESCRIPTION

[0023] See also Figure 1-7 , the embodiments of the utility model are further described;

[0024] A protective safety railing for construction engineering, comprising a plurality of railing bodies 1;

[0025] The railing body 1 is provided with a connecting member 2, and the connecting member 2 includes a plurality of mounting blocks 21, an insert block 22 and a hinge 23. The plurality of hinges 23 are respectively installed on both sides of the railing body 1, a plurality of mounting blocks 21 are arranged on one side of the railing body 1, and a plurality of insert blocks 22 are arranged on the other side of the railing body 1. The mounting blocks 21 and the insert blocks 22 are respectively fixedly connected to the hinges 23 adjacent thereto, and the mounting block 21 is clamped with the insert block 22 on another railing body 1.

[0026] In this embodiment, Figure 1-2 As shown, if two railing bodies 1 need to be assembled together, align the mounting block 21 on one of the railing bodies 1 with the plug-in block 22 on the other railing body 1, and insert the plug-in block 22 into the adjacent mounting block 21 and snap it together, so that the two railing bodies 1 are positioned together. The installation method is simple, and the two railing bodies 1 can be quickly assembled together without the aid of tools, and can be used as safety protection at balconies and stairways. If more railing bodies 1 are needed to surround the balcony or stairway, the remaining railing bodies 1 can be assembled together according to the above operation. When disassembling the protective safety railing, the operation can be performed in the reverse order of installation, so that the protective safety railing can be split into multiple railing bodies 1.

[0027] like Figure 3 As shown, if the shape of the protective safety railing needs to be changed according to the balcony terrain, the staff can rotate the railing body 1, and the railing body 1 will drive the hinge 23 to rotate, so that the angle between the railing body 1 and another railing body 1 can be adjusted. The operation is simple and it is convenient to change the shape of the protective safety railing according to actual conditions.

[0028] Limiting grooves 211 are formed on both sides of the inner wall of the installation block 21 , and through holes 223 are formed on the side of the insertion block 22 . Limiting blocks 225 are installed at both ends of the through holes 223 , and the limiting blocks 225 are engaged with the adjacent limiting grooves 211 .

[0029] In this embodiment, when the inserting block 22 is plugged into the mounting block 21 , the limiting block 225 on the inserting block 22 will be snapped into the limiting groove 211 on the inner wall of the mounting block 21 , so that two adjacent railing bodies 1 are connected together.

[0030] A accommodating cavity 221 communicating with the through hole 223 is formed at the top of the insert block 22, a driving member for driving the two limit blocks 225 is installed between the accommodating cavity 221 and the inside of the through hole 223, the upper end of the driving member extends out of the accommodating cavity 221, and a limiting member for limiting the two limit blocks 225 is fixed in the through hole 223.

[0031] In this embodiment, after the insertion block 22 and the mounting block 21 are plugged in, the staff can use the driving member to drive the two limit blocks 225, so that the two limit blocks 225 are respectively inserted into the two limit grooves 211, so that the insertion block 22 and the mounting block 21 are limited together. The setting of the limit member is to make the two limit blocks 225 move according to the designed trajectory.

[0032] The driving member includes an external gear 222, a bidirectional threaded rod 226 and an internal gear 228. The bidirectional threaded rod 226 is rotatably connected to the through hole 223. The two limit blocks 225 are sleeved on both ends of the bidirectional threaded rod 226 and threadedly connected thereto. The internal gear 228 is sleeved and fixed on the middle part of the bidirectional threaded rod 226. The external gear 222 is rotatably connected to the accommodating cavity 221, and the lower end of the external gear 222 is meshed with the internal gear 228, and the upper end extends out of the accommodating cavity 221.

[0033] In this embodiment, after the plug block 22 is plugged into the mounting block 21, the outer gear 222 is rotated clockwise, and the outer gear 222 drives the inner gear 228 to rotate, so that the bidirectional threaded rod 226 drives the two limit blocks 225. Due to the existence of the limiter, the two limit blocks 225 can be limited to prevent the two limit blocks 225 from rotating with the bidirectional threaded rod 226, so that the two limit blocks 225 can enter the two limit grooves 211 respectively, so that the plug block 22 is stuck in the mounting block 21, and the stability of the connection between the two adjacent railing bodies 1 is enhanced;

[0034] If the protective safety railing is not needed, the staff can rotate the outer gear 222 counterclockwise. After the outer gear 222 transmits the inner gear 228 and the bidirectional threaded rod 226, it will drive the two limit blocks 225 to move out of the two limit grooves 211 respectively, so that the two railing bodies 1 can be separated.

[0035] The protective safety railing is easy to install and disassemble, making it convenient for workers to quickly install or disassemble the protective safety railing.

[0036] The limiting member includes two limiting strips 224, and limiting holes 227 are formed on both sides of the limiting block 225. The limiting strips 224 are slidably connected with adjacent limiting strips 224;

[0037] In this embodiment, when the limiting block 225 moves, the two limiting strips 224 will slide in the two limiting strips 224 respectively. The arrangement of the limiting strips 224 and the limiting holes 227 is conducive to the stable movement of the limiting block 225.
