[0040] 1. In use, by pulling the limiting rod outward, the limiting rod moves out of the first limiting groove. At the same time, the sliding plate moves synchronously to compress the first spring. At this time, the sleeve rod can be moved downward, so that the support rod rotates through the action of the connecting rod until the limiting rod is collinear with the second limiting groove. Then, the limiting rod is released, and the limiting rod extends into the second limiting groove under the release action of the first spring, fixing the sleeve rod. At this time, it can be stably supported by the support rod.
[0041] 2. When assembling the guardrail, simultaneously insert the connecting rod and connecting block into the connecting sleeve and connecting groove on the adjacent guardrail, and simultaneously slide the sliding sleeve to the left to compress the second spring. When the connecting block extends into the connecting sleeve and contacts the locking rod, push the locking rod outward until the connecting block is placed in the connecting sleeve. After releasing the sliding sleeve, the second spring releases the sliding sleeve to return to its original position to the right. Through the action of the limiting groove, the locking rod is pushed inward, so that the locking rod is stably inserted into the locking groove, fixing the connecting block. This fixes adjacent guardrails, making it easy to connect and fix multiple guardrails in sequence for construction, while improving overall stability and ensuring construction safety.

[0048] 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.
[0049] Please see Figure 1-5The present invention provides a highly stable modular construction safety guardrail, comprising a horizontal bar 1, vertical bars 2 fixedly and vertically installed on the top surface of the horizontal bar 1, and three vertical bars 2 are provided, with a fixing shaft 3 fixedly penetrating the vertical bars 2.
[0050] A sleeve rod 4 is fitted on the outside of the vertical rod 2 and is slidably connected to the vertical rod 2. A cavity 5 is opened inside the sleeve rod 4. A limiting rod 6 is movably inserted through the outside of the sleeve rod 4 into the cavity of the sleeve rod 4 and is movably inserted through the cavity 5. A sliding plate 7 is fixedly fitted on the limiting rod 6 and is slidably connected to the cavity 5. A first spring 8 is fitted on the outside of the limiting rod 6 and is fixedly connected to the outer wall of the cavity 5. The inner end of the first spring 8 is fixedly connected to the outer side of the sliding plate 7. A first limiting groove 9 is opened on the side of the middle vertical rod 2 near the limiting rod 6 and matches the limiting rod 6. A second limiting groove 10 is opened on the middle vertical rod 2 and matches the limiting rod 6, ensuring that the position of the sleeve rod 4 is limited and fixed.
[0051] Two symmetrically arranged fixed seats 11 are fixedly installed on the bottom surface of the sleeve rod 4. The top end of the support rod 12 is rotatably connected to the fixed seat 11. The support rod 13 is fitted onto the fixed shaft 3 and is connected to the fixed shaft 3 by a bearing. The end of the support rod 13 away from the fixed shaft 3 is rotatably connected to the bottom end of the support rod 12, ensuring that the support rod 13 can be unfolded and supported on the ground, thus improving the stability of the guardrail.
[0052] The connecting sleeve 14 is fixedly installed on the right end of the crossbar 1. Two symmetrically arranged sliding grooves 15 are opened on the outer side of the connecting sleeve 14. The sliding sleeve 16 is fitted on the outer side of the connecting sleeve 14, and the slider 17 on the inner wall of the sliding sleeve 16 is slidably connected to the sliding groove 15. The left end of the second spring 18 is fixedly connected to the left wall of the sliding groove 15, and the right end of the second spring 18 is fixedly connected to the left side of the slider 17. Two symmetrically arranged limiting grooves 19 are opened on the inner wall of the sliding sleeve 16, and the limiting grooves 19 are located on the right side of the slider 17. (The last sentence appears to be incomplete and possibly refers to a different component.) The 20-moving connecting sleeve 14 is set in the side wall, and the outer end of the 20 is located in the limiting groove 19. Both the inner and outer ends of the 20 are semi-circular. The limiting piece 21 is fixedly fitted on the 20 and is located on the outside of the connecting sleeve 14. The connecting rod 22 is fixedly installed on the left end of the crossbar 1 and matches the connecting sleeve 14. The slot 23 is opened on the surface of the connecting rod 22 and is semi-circular and matches the 20, which facilitates the assembly of adjacent guardrails.
[0053] A connecting block 24 is fixedly installed on the left end face of the fixed shaft 3, and a connecting groove 25 is opened on the right end face of the fixed shaft 3. The connecting block 24 matches the connecting groove 25, which improves the stability of the guardrail assembly connection.
[0054] Working principle: In use, firstly, the limiting rod 6 is pulled outward to make the sliding plate 7 move synchronously and compress the first spring 8. After the limiting rod 6 moves outward from the first limiting groove 9, the sleeve rod 4 can be moved downward. At this time, through the action of the fixed seat 11 and the support rod 12, the support rod 13 rotates around the fixed shaft 3 until the limiting rod 6 moves downward with the sleeve rod 4 to the second limiting groove 10. After releasing the limiting rod 6, the sliding plate 7 drives the limiting rod 6 to move inward to reset under the release action of the first spring 8, so that the limiting rod 6 extends into the second limiting groove 10, thereby fixing the sleeve rod 4. Thus, the support rod 13 and the vertical rod 2 provide stable support.
[0055] During the assembly of the guardrail, the connecting rod 22 and connecting block 24 are respectively inserted into the connecting sleeve 14 and connecting groove 25 of the adjacent guardrail. Simultaneously, the sliding sleeve 16 can be slid to the left, causing the slider 17 to slide to the left, compressing the second spring 18. At the same time, the limiting groove 19 moves to the left along with the sliding sleeve 16. After the connecting rod 22 contacts the locking rod 20, the locking rod 20 can be pushed outwards. When the connecting rod 22 extends into the connecting sleeve 14, the locking rod 20 is collinear with the locking groove 23. At this point, after releasing the sliding sleeve 16, the release of the second spring 18... The slider 17 drives the sliding sleeve 16 and the limiting groove 19 to move back and forth to the right, so that the limiting groove 19 pushes the locking rod 20 to move inward, thereby allowing the locking rod 20 to extend into the locking groove 23 and fix the connecting rod 22, thus realizing the connection and assembly of the guardrail. By assembling multiple guardrails, an effective enclosure and protection function is activated. At the same time, the overall integrity of multiple guardrails after assembly is stronger, making the overall stability stronger and effectively ensuring construction safety. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
