Description

Technical Field

[0001] This utility model relates to the field of edge protection technology, and in particular to a self-locking guardrail for edge protection at construction sites. Background Technology

[0002] On construction sites, the safety protection of edge areas (such as openings and floor edges) is a crucial aspect of ensuring construction safety. Handrails are the core facility for achieving edge protection, and the two form a complete protection system through specific connection structures. The effectiveness of edge protection directly depends on the stable installation and reliable connection of the handrails—handrails typically consist of posts and guardrail panels. The posts are fixed to the foundation structure at the edge, serving as the supporting framework of the entire protection system. The guardrail panels are connected to the posts through specific connecting components, forming a horizontal or vertical isolation barrier, thereby preventing personnel and materials from accidentally falling and fulfilling the function of edge protection.

[0003] During the installation of edge railings, we found that traditional railing connection methods require tools to complete installation and disassembly, which is time-consuming and labor-intensive. Especially when the construction schedule is tight or the edge area changes frequently, the adaptability is poor, wasting a lot of manpower and time. Utility Model Content

[0004] The main purpose of this utility model is to provide a self-locking guardrail for edge protection at construction sites, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a self-locking guardrail for edge protection at construction sites, comprising a post and a protective plate, wherein a self-locking mechanism is provided on the upper and lower sides of the post, and a connecting mechanism is provided at the four corners of the protective plate, and the self-locking mechanism and the connecting mechanism are connected. The self-locking mechanism includes a U-shaped seat, a stop bar, a slide groove, and a crossbar. The left side of the U-shaped seat is installed on the upper and lower sides of the column. The front and rear ends of the crossbar are rotatably connected to the lower right side of the U-shaped seat. The middle part of the crossbar is slidably connected inside the slide groove, which is located in the lower middle part of the stop bar.

[0006] Preferably, the stop bar is L-shaped, and a rubber pad is provided on the lower part of the stop bar near the column.

[0007] Preferably, a counterweight is installed at the lower part of the stop bar.

[0008] Preferably, a pull ring is provided at the upper end of the stop bar.

[0009] Preferably, the connecting mechanism includes a connecting frame and rollers. The front and rear ends of the rollers are rotatably connected to one end of the connecting frame, and the other end of the rollers is slidably connected to the four corners of the protective plate. The rollers are disposed inside the U-shaped groove of the U-shaped seat.

[0010] Preferably, reflective strips are provided on the front and rear sides of the protective plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. With the help of the self-locking mechanism and the connecting mechanism, after the roller is inserted into the U-shaped seat during installation, the stop bar can automatically reset and lock under the action of the counterweight; when disassembling, the lock can be released by pulling the pull ring. No complicated tools are required, which greatly simplifies the operation and saves manpower and time. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-3 As shown, a self-locking guardrail for edge protection at a construction site includes a post 1 and a protective plate 4. The post 1 is provided with a self-locking mechanism 2 on its upper and lower sides, and the protective plate 4 is provided with a connecting mechanism 3 at its four corners. The self-locking mechanism 2 and the connecting mechanism 3 are connected to each other.

[0016] In this embodiment, the self-locking mechanism 2 includes a U-shaped seat 201, a stop bar 202, a slide groove 203, and a crossbar 204. The left side of the U-shaped seat 201 is installed on the upper and lower sides of the column 1. The front and rear ends of the crossbar 204 are rotatably connected to the lower right side of the U-shaped seat 201. The middle part of the crossbar 204 is slidably connected to the inside of the slide groove 203. The slide groove 203 is opened in the lower middle part of the stop bar 202. A counterweight 206 is installed at the lower part of the stop bar 202. A pull ring 205 is provided at the upper end of the stop bar 202. The connecting mechanism 3 includes a connecting frame 301 and a roller 302. The front and rear ends of the roller 302 are rotatably connected to one end of the connecting frame 301. The other end of the roller 302 is slidably connected to the four corners of the protective plate 4. The roller 302 is set inside the U-shaped groove of the U-shaped seat 201.

[0017] Specifically, during installation, first fix the two uprights 1 near the opening, then place the protective plate 4 on the ground between the two uprights 1. Next, pull the connecting bracket 301 to insert the roller 302 into the U-shaped groove of the U-shaped seat 201. At this time, the roller 302 will press against the upper part of the stop bar 202, causing the stop bar 202 to rotate and tilt. After the roller 302 passes the top of the stop bar 202, the stop bar 202 returns to its original position under the weight of the counterweight 206. Since the stop bar 202 is L-shaped, its lower part will abut against the outside of the upright 1, thus restricting the stop bar 202 from flipping outwards, allowing the upper part of the stop bar 202 to... The roller 302 is positioned around its outer perimeter, securing it firmly within the U-shaped groove of the U-shaped seat 201. The remaining corners of the protective plate 4 are then installed in the same manner to complete the overall installation. During disassembly, the pull ring 205 is pulled upwards to move the stop bar 202 upwards, while simultaneously pulling the connecting frame 301 outwards. This causes the roller 302 to press against the stop bar 202. Because the lower radius of rotation of the stop bar 202 decreases after it is pulled up, the column 1 cannot block the lower part of the stop bar 202 when it flips outwards, allowing the roller 302 to easily detach from the U-shaped seat 201, thus facilitating easy disassembly.

[0018] In this embodiment, the baffle 202 is L-shaped, and a rubber pad is provided on the lower part of the baffle 202 near the column 1. Reflective strips 5 are provided on the front and rear sides of the protective plate 4.

[0019] Specifically, in situations where there is insufficient light at the construction site, such as at night, during rainy weather, or in areas with complex lighting, the reflective strip 5 can reflect external light, such as flashlight beams and vehicle headlights, making the guardrails more conspicuous. This effectively reminds construction workers to pay attention to the edge, preventing accidents such as falls due to poor visibility, and further improving the safety protection level of the construction site.

[0020] Working principle: During installation, first fix the two uprights 1 near the opening, then place the protective plate 4 on the ground between the two uprights 1. Next, pull the connecting bracket 301 to insert the roller 302 into the U-shaped groove of the U-shaped seat 201. At this time, the roller 302 will press against the upper part of the stop bar 202, causing the stop bar 202 to rotate and tilt. After the roller 302 passes the top of the stop bar 202, the stop bar 202 returns to its original position under the weight of the counterweight 206. Since the stop bar 202 is L-shaped, its lower part will abut against the outside of the upright 1, thus restricting the stop bar 202 from flipping outwards, allowing the upper part of the stop bar 202 to block... Roller 302 is securely locked into the U-shaped groove of U-shaped seat 201 around its outer periphery. Then, the remaining corners of the protective plate 4 are installed in the same manner to complete the overall installation. When disassembling, pull the pull ring 205 upward to move the stop bar 202 upward, and at the same time pull the connecting frame 301 outward to make the roller 302 squeeze the stop bar 202 outward. Because the rotation radius of the lower end of the stop bar 202 is reduced after the stop bar 202 is pulled up, when the stop bar 202 flips outward, the column 1 cannot block the lower part of the stop bar 202, and the roller 302 can be smoothly separated from the U-shaped seat 201, realizing convenient disassembly.
