[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Example 1 like Figure 1-5 As shown, this utility model provides a connecting component for a prefabricated edge protection railing, including multiple guardrails 1. A connecting mechanism 2 is provided on the opposite faces of two adjacent guardrails 1. The connecting mechanism 2 includes a sliding groove 201 and a limiting groove 202. Both ends of the sliding groove 201 are open. A locking rod 203 is slidably connected inside both ends of the sliding groove 201. A closing plate 204 is fixedly connected to both ends of the sliding groove 201. Two bidirectional screws 205 are rotatably connected inside the two closing plates 204 via bearings. Two locking rods 203 are threaded onto the outer surfaces of both ends of the bidirectional screws 205. The limiting groove 202 has openings on both sides. A slot 206 is provided, which cooperates with the locking rod 203. A T-shaped rail 207 is fixedly connected to the bottom surface of the inner cavity of the slide groove 201. A T-shaped groove is opened on the bottom surface of the locking rod 203, which cooperates with the T-shaped rail 207. Guide grooves 208 are opened on both sides of the inner surface of the slide groove 201. A slider is fixedly connected to both sides of the locking rod 203, and the slider is slidably connected to the guide groove 208. Stepped holes are opened on both sides of the bottom surface of the slide groove 201 and the limiting groove 202. Screws are installed inside the stepped holes. One end of the bidirectional screw 205 rotates through the side of a closed plate 204 and is fixedly connected to an operating connector 209. A hexagonal hole is opened inside the operating connector 209.

[0019] In this embodiment, the sliding groove 201 and the limiting groove 202 are respectively fixedly connected to two adjacent guardrails 1 through stepped holes and screws. Before connecting the two adjacent guardrails 1, a hex wrench is inserted into the hexagonal hole opened inside the operating connector 209. Rotating the hex wrench drives the operating connector 209 and the bidirectional screw 205 to rotate. The bidirectional screw 205 is connected to two locking rods 203, which drive the two locking rods 203 to slide in the sliding groove 201 and move closer to each other. The two closing plates 204 are connected to the bidirectional screw 205 through bearings to support the bidirectional screw 205 and improve the rotational stability of the bidirectional screw 205. The T-shaped rail 207 is connected to the T-shaped groove, and the guide groove 208 is connected to the slider to limit the movement direction and movement range of the two locking rods 203 and improve the movement stability of the two locking rods 203. When the two locking rods 203 move to the appropriate position, the rotation of the hex wrench is stopped to fix the position of the two locking rods 203. When connecting two adjacent guardrails 1, pushing one guardrail 1 moves the slide 201 and causes the locking rod 203 to enter the limiting groove 202. When one end of the locking rod 203 is fully inserted into the limiting groove 202, the hex wrench is rotated to reverse the operating connector 209 and the double-ended screw 205. The double-ended screw 205 causes the two locking rods 203 to slide synchronously in the slide 201 and move away from each other. As the locking rods 203 move, one end of the locking rod 203 enters the locking groove 206. When one end of the locking rod 203 is fully inserted into the locking groove 206, the hex wrench is stopped to fix the position of the two locking rods 203. The locking rods 203 are connected to the slide 201 and the locking groove 206 respectively to connect the slide 201 and the limiting groove 202, thereby connecting the two adjacent guardrails 1. During use, the T-shaped rail 207 and the guide groove 208 restrict the movement direction of the locking rod 203 through the T-shaped groove and the slider, respectively, to prevent the locking rod 203 from bending the bidirectional screw 205 when subjected to lateral force, thereby improving the service life of the bidirectional screw 205.

[0020] Example 2 like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the guardrail 1 includes uprights 101, the uprights 101 are in pairs, and the opposite faces of the two uprights 101 are linearly arrayed and fixedly connected to a bracket 102, and the inside of the bracket 102 is fixedly connected to a crossbar 103 by bolts.

[0021] In this embodiment, multiple brackets 102 are connected by two uprights 101, and multiple crossbars 103 are connected by multiple brackets 102 to form the whole of the guardrail 1. The crossbars 103 are telescopic bars, which facilitates the adjustment of the protective length of the guardrail 1 and improves the adaptability of the guardrail 1. The bracket 102 is connected to the crossbar 103 by bolts, which facilitates the disassembly, replacement and installation of the crossbar 103; When connecting two adjacent guardrails 1, the sliding groove 201 and the limiting groove 202 are placed on the two adjacent uprights 101 respectively. The uprights 101 have threaded holes on their sides. After aligning the stepped holes on the sliding groove 201 and the limiting groove 202 with the threaded holes, screws are screwed into the stepped holes and the threaded holes to connect and fix the guardrail 1 and the sliding groove 201, and the guardrail 1 and the limiting groove 202.
