Description

Technical Field

[0001] The utility model relates to the technical field of adjustable guardrails for municipal roads, and more specifically, to an adjustable guardrail for municipal roads. Background Art

[0002] In current municipal engineering, adjustable guardrail systems play a vital role in road safety, especially in scenarios that need to adapt to different traffic or weather conditions. Such guardrails usually need to be pre-configured according to the specific road conditions and the expected use environment before installation to ensure that their performance is optimized. However, existing adjustable guardrail technology faces several significant problems. First, once the guardrails are installed and fixed, they are often difficult to be easily disassembled or reconfigured. This is mainly because guardrail systems usually use rigid connection elements such as bolts or welding, which provide the necessary structural strength but greatly limit the flexibility and adaptability of the guardrail. In practical applications, this design not only increases the difficulty of maintenance and adjustment, but also means that once the guardrail needs to be reconfigured for different usage scenarios, the whole process may become time-consuming and laborious.

[0003] In addition, the rigid connection parts of existing adjustable guardrails are prone to breakage or damage when encountering large external forces, such as vehicle collisions. This situation not only reduces the overall safety of the guardrail, but also increases the risk of accidents, which may lead to more serious traffic accidents. The disadvantage of rigid connection is that it cannot provide sufficient elasticity or deformation space when subjected to impact, making it impossible for the guardrail to effectively absorb and disperse the impact force when encountering sudden forces, which directly affects the function and durability of the guardrail.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides an adjustable guardrail for municipal roads, which has the following beneficial effects:

[0017] 1. The adjustment mechanism provides the guardrail with flexible height adjustment capabilities to adapt to different roads and environmental requirements. Through the coordinated use of internal and external springs, and the sliding connection between the insertion rod and the positioning block, this mechanism can ensure structural stability. In addition, by avoiding rigid connections, the mechanism can provide a certain degree of elasticity when encountering large external forces, thereby reducing damage caused by impact and increasing the service life and safety of the guardrail.

This stable fixing method not only ensures the safety of the guardrail, but also enables the guardrail to withstand longer use and a wider range of applications, providing a solid guarantee for the safety of municipal roads.

The upper and lower ends of the positioning block 5 are respectively provided with rounded corners 21. The clamping mechanism includes a clamping rod 10. A plurality of telescopic holes 11 are provided on the side wall of the follower sleeve 8. Each telescopic hole 11 is slidably connected with the clamping rod 10. A spiral groove 12 is provided on the side wall of the insertion rod 3. A round head 13 is provided on one side of each clamping rod 10 that clamps the inside, and the round head 13 is pressed against the spiral groove 12. A contact head 14 is provided on the outer side of each clamping rod 10. A limiting ring 15 is coaxially provided on each contact head 14, and the limiting ring 15 is fitted on the outer wall of the follower sleeve 8.

[0030] In this embodiment, when pre-installation is required, first adjust the threaded sleeve 18 to the position where multiple elastic sheets 16 fit against the abutment head 14, then insert the insertion rods 3 at both ends into the follower sleeve 8 respectively, and insert the positioning block 5 into the positioning hole 9 at the same time. Then, due to the elastic setting of the elastic sheet 16, the clamping rod 10 can slide in the telescopic groove and also apply a certain elastic force.

Since the spiral grooves 12 at both ends are in contact with the round heads 13, they will be fixed after insertion, and the elastic force can only be within the elastic force range of the elastic sheet 16. Therefore, they can be directly inserted, and the rigid connection between the vertical rod 2 and the fixing seat 6 is avoided by the joint action of the internal spring 4 and the external spring 7, thereby avoiding the situation where the vertical rod 2 is broken due to a large force, thereby ensuring the safety of use.

[0031] See also Figure 3 As an implementation method of the limiting mechanism: the limiting mechanism includes an elastic sheet 16, a plurality of elastic sheets 16 are provided, each elastic sheet 16 is provided with a compensation groove 17, the abutment head 14 is pressed against the inner wall of the elastic sheet 16, a plurality of elastic sheets 16 are respectively provided with a threaded sleeve 18, the threaded sleeve 18 is threadedly connected to the follower sleeve 8, a fixing groove 19 is provided in the threaded sleeve 18, a rubber strip 20 is coaxially provided in the fixing groove 19, and the rubber strip 20 abuts against the plurality of elastic sheets 16.
