Description

Technical Field

[0001] This utility model relates to the field of assembled guardrail technology, and in particular to a quick-assembly guardrail. Background Technology

[0002] With the accelerating pace of urban construction and the upgrading of safety standards, the industry has increasingly higher requirements for the installation efficiency, structural strength, and environmental protection of protective facilities. At the same time, the maturity of modular design and convenient connection technologies (such as quick-connect buckles and self-locking joints) has provided technical support for rapid assembly of guardrails. These guardrails can be quickly assembled without tools, adapt to the protection height and range of different scenarios, and take into account both construction efficiency and resource conservation, making them an important solution in the field of modern engineering protection.

[0003] Traditional interlocking guardrails typically consist of support rods and crossbars connected by threads, with openings on the surface of multiple crossbars for inserting guardrail sections, allowing for quick assembly. However, during use, the upper joints of the guardrails are susceptible to vibration stress, causing the threaded connections at both ends to loosen. Over time, this can lead to the guardrails falling apart due to loosening at the joints.

[0004] Therefore, we provide a quick-assembly guardrail to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a quick-assembly guardrail to solve the problems mentioned in the background art.

[0011] Compared with the prior art, the beneficial effects of this utility model are: As shown in the figure, this utility model features a bottom-plugged, mid-section auxiliary clamping quick-installation mechanism. This mechanism uses plug-in guardrail positioning components at the lower middle of two adjacent bottom-support guardrail brackets. The fixed guardrail can be plugged into the bottom support rod and further secured using the bottom-plugged guardrail fixing components. This clamps and secures the bottom of multiple guardrails. Furthermore, multiple segmented adjacent guardrail auxiliary clamping and fixing components are used at the top of the fixed plug-in guardrail for additional fixation. These components use rotating and adjustable guardrail clamping components at both ends to clamp and secure the fixed plug-in guardrail. The central rubber sleeve cushions the vibration stress, preventing the bolt connections at both ends from loosening or falling off. This design increases ease of assembly and extends the overall service life of the guardrail. Attached Figure Description

[0013] 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.

[0014] Please see Figure 1-4 As shown, this utility model provides a technical solution: a quick-assembly guardrail, including a bottom support guardrail bracket 1 and a bottom insertion and middle auxiliary clamping quick installation mechanism 2. The bottom support guardrail bracket 1 is provided with a bottom insertion and middle auxiliary clamping quick installation mechanism 2 on one side. The bottom-plug-in middle auxiliary clamping quick installation mechanism 2 includes a plug-in guardrail positioning component 21, a bottom plug-in guardrail fixing component 22, a segmented adjacent guardrail auxiliary clamping fixing component 23, and a rotating adjustable guardrail clamping component 24. The plug-in guardrail positioning component 21 is provided on one side of the bottom supporting guardrail bracket 1. The bottom plug-in guardrail fixing component 22 is provided on the inner side of the plug-in guardrail positioning component 21. The segmented adjacent guardrail auxiliary clamping fixing component 23 is provided on the surface of the bottom plug-in guardrail fixing component 22. The rotating adjustable guardrail clamping component 24 is provided on both sides of the segmented adjacent guardrail auxiliary clamping fixing component 23.

[0015] Furthermore, the plug-in guardrail positioning component 21 includes a welded plug-in bracket 211, a bottom fixed support rod 212 of the guardrail, and an auxiliary fixing bolt 213. The welded plug-in bracket 211 is welded and fixed to the inner side of the bottom supporting guardrail bracket 1, and the bottom fixed support rod 212 of the guardrail is movably plugged into one side of the welded plug-in bracket 211. The bottom fixed support rod 212 of the guardrail is threadedly fixed to the welded plug-in bracket 211 through the auxiliary fixing bolt 213. In use, the welded plug-in brackets 211 welded at both ends of the bottom supporting guardrail bracket 1 can thread-fix the bottom fixed support rod 212 of the guardrail through the auxiliary fixing bolt 213. While fixing the bottom supporting guardrail brackets 1 at both ends, the bottom positioning plug-in fixing of multiple fixed plug-in guardrails 223 at the top is also achieved.

[0016] Furthermore, the bottom-plug-in guardrail fixing assembly 22 includes a top-plug-in sealing sleeve 221, a bottom-fixed plug-in collar 222, a fixed plug-in guardrail 223, and an auxiliary plug-in fixing rod 224. The top of the bottom fixed support rod 212 is fixedly plugged into the top of the top-plug-in sealing sleeve 221, and the bottom of the bottom fixed support rod 212 is fixedly plugged into the bottom of the bottom fixed support rod 212. The fixed plug-in guardrail 223 is movably plugged into the inner side of the top-plug-in sealing sleeve 221. The fixed plug-in guardrail 223 passes through the bottom fixed plug-in collar 222 and is plugged into and fixed to the bottom fixed plug-in collar 222 via the auxiliary plug-in fixing rod 224. In use, the top-plug-in sealing sleeve 221 and the bottom fixed plug-in collar 222 are respectively provided at the upper and lower ends of the bottom fixed support rod 212. Figure 4 It can be seen that the bottom fixed plug-in collar 222 plugs and fixes the through fixed plug-in guardrail 223 by auxiliary plug-in fixing rod 224, thereby stabilizing the bottom of the fixed plug-in guardrail 223.

[0017] Furthermore, the segmented adjacent guardrail auxiliary clamping and fixing assembly 23 includes a sleeved rubber sleeve 231, a through-fixed support rod 232, and a through-insertion rotating support rod 233. A sleeved rubber sleeve 231 is provided on one side of the fixed insertion guardrail 223, and through-fixed support rods 232 are fixedly sleeved on both sides of the sleeved rubber sleeve 231. Through-insertion rotating support rods 233 are rotatably sleeved at the ends of the through-fixed support rods 232. In use, after the rotating adjustable guardrail clamping assembly 24 at both ends of the through-fixed support rod 232 wraps and fixes the fixed insertion guardrails 223 at both adjacent ends, the sleeved rubber sleeve 231 in the middle can buffer the vibration stress between the fixed insertion guardrails 223, preventing the stress from being directly transmitted to the threaded connection at both ends, which could cause the connection to loosen.

[0018] Furthermore, the rotating adjustable guardrail clamping assembly 24 includes a semi-circular rotating clamping bracket 241, an auxiliary anti-slip rubber arc strip 242, a through-threaded support rod 243, and an internally threaded fastening nut 244. The end of the through-fixed support rod 232 is rotatably sleeved with the semi-circular rotating clamping bracket 241 through the through-threaded rotating support rod 233. The auxiliary anti-slip rubber arc strip 242 is fixedly adhered to the inner side of the semi-circular rotating clamping bracket 241. Both ends of 41 are connected to through-threaded support rods 243. Both ends of the through-threaded support rods 243 are threaded with internal thread fastening nuts 244. In use, the adjacent semi-circular rotating clamping brackets 241 wrap the fixed plug-in guardrail 223 through the auxiliary anti-slip rubber arc strip 242 bonded in the middle, and the outer end of the through-threaded support rods 243 is threadedly fixed by the internal thread fastening nuts 244, so as to realize the clamping and fastening operation of the fixed plug-in guardrail 223.
