In this utility model, when the support plate 1 and support plate 2 move in opposite directions, the scissor bar 4 can be moved by the bracket 2 on the support plate 1 and support plate 2. One end of the scissor bar 4 drives the slider 2 to slide up and down in the groove of the support bar 2, thereby completing the extension and retraction to the left or right. When the pull rope 1 and pull rope 2 are taut, the maximum extension and retraction length is reached, which can be used for movement during extension or movement to different positions as needed. One side of the support plate 1 and support plate 2 is also provided with a threaded support leg. When moved to the desired position, the handle is turned downwards to fix the folding safety guardrail.

[0004] This patent uses a handle to twist downwards to secure the folding safety barrier. However, existing devices are all large in size, inconvenient to carry, laborious to transport, and cannot adjust the overall length of the barrier according to actual conditions, so their practicality needs to be improved.

[0005] Therefore, we propose a new type of foldable safety guardrail for construction projects. Utility Model Content

[0008] Furthermore, the position and size of the insertion rod match the position and size of the insertion hole, and the insertion rod and the insertion hole form a mating connection.

[0009] Furthermore, one side of one set of the guardrail bodies is connected to a rotating buckle, and the other side of the guardrail bodies is connected to a locking block, wherein the locking block and the rotating buckle are engaged and fixed together.

[0010] Furthermore, a hinge connects one set of the guardrail bodies to another set of the guardrail bodies, and the pull rod and spring form an elastic structure.

[0011] Furthermore, the front surfaces of both sets of guardrail bodies are connected to a disassembly assembly, which includes a frame and an installation groove inside the frame.

[0012] Furthermore, a prompting plate is provided inside the mounting slot, and magnetic blocks are connected to both outer surfaces of the prompting plate.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figure 1 - Figure 5 As shown, this utility model provides a foldable safety guardrail for construction engineering, including a guardrail body 1. The guardrail body 1 has a telescopic folding assembly 2 inside. The telescopic folding assembly 2 includes a sliding plate 201. The top of the sliding plate 201 has equidistant insertion holes 202. A fixing block 203 is connected to the top of one side of the guardrail body 1. A spring 204 is installed inside the fixing block 203. A pull rod 205 is inserted into the spring 204. A plug 206 is connected to the bottom of the pull rod 205. A pull block 207 is connected to the top. The position and size of the insertion rod 206 match the position and size of the insertion hole 202. The insertion rod 206 and the insertion hole 202 form an insertion connection. A rotating buckle 208 is connected to one side of one set of guardrail bodies 1. A locking block 209 is connected to one side of another set of guardrail bodies 1. The locking block 209 and the rotating buckle 208 form a locking and fixing connection. A hinge 210 is connected between one set of guardrail bodies 1 and another set of guardrail bodies 1. The pull rod 205 and the spring 204 form an elastic structure.

[0027] The overall effect of Embodiment 1 is that, when needed, the two sets of guardrail bodies 1 can be opened by rotating the hinge 210, and then the rotating buckle 208 and the locking block 209 can be locked together. Then, the pull block 207 can be pulled upward, so that the pull block 207 can drive the pull rod 205 to retract upward. When the pull rod 205 moves upward, it will also compress the spring 204 and drive the insertion rod 206 to be pulled out of the insertion hole 202 at the current position. Then, the sliding plate 201 can be pulled outward. After adjusting to a suitable length, it can be released. Pull block 207 allows spring 204 to push pull rod 205 through its own elasticity, causing insertion rod 206 to be inserted into insertion hole 202 for fixation. When the guardrail body 1 needs to be folded for transportation, first retract the slide plate 201 into the guardrail body 1 by opening it, and then remove the rotating buckle 208 from the surface of the locking block 209. At this time, the two sets of guardrail bodies 1 can be folded. The length can be adjusted according to the actual situation, avoiding the problem that the existing guardrail is not easy to fold and cannot adjust the length of use, thus improving the overall practicality.

[0028] Example 2, as Figure 1 and Figure 6 As shown, the front surfaces of both sets of guardrail bodies 1 are connected to disassembly and assembly components 3. The disassembly and assembly components 3 include a frame 301. The frame 301 has an installation groove 302 inside. The installation groove 302 has a prompting plate 303 inside. The outer surfaces of both sides of the prompting plate 303 are connected to magnetic blocks 304. The inner walls of both sides of the installation groove 302 are provided with magnets. The magnetic blocks 304 and the magnets form a magnetic connection.

[0029] The effect achieved by the entire embodiment 2 is that when the prompt plate 303 needs to be replaced, the prompt plate 303 can be pulled upward so that the prompt plate 303 can be pulled out from the mounting slot 302, and then the required prompt plate 303 can be inserted into the mounting slot 302 so that the magnetic block 304 can be magnetically attracted and fixed with the magnet, which reduces the replacement time of the prompt plate 303 and improves work efficiency.

[0030] Working principle: When folding and retracting the main body 1 of the guardrail, the sliding plate 201 can be retracted into the main body 1 of the guardrail. Then, the two sets of main bodies 1 of the guardrail can be folded in opposite directions. After folding, the volume is small, which is convenient for carrying and transportation. In addition, the length can be adjusted according to the actual situation during use, avoiding the problem that the existing guardrail is not easy to fold and cannot adjust the length of use, thus improving the overall practicality. The sliding connection between the indicator plate 303 and the frame 301 can realize the quick replacement of the indicator plate 303. Different indicator plates 303 can be replaced in different usage scenarios, reducing replacement time and improving work efficiency.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
