Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of road guardrails, and particularly relates to a road guardrail for marathons. BACKGROUND

[0002] With the vigorous development of national fitness, marathon events are in full swing everywhere. During event preparation, track planning is extremely critical, and road guardrail arrangement is the most important for ensuring the safety and order of the event. Traditional road guardrails are often permanently welded or deeply embedded and fixed on both sides of the road. In daily traffic management, the stability and safety are acceptable, but problems frequently occur in the face of temporary needs of marathon events. During the event, continuous road guardrails need to be quickly erected in specific track areas to separate the track and the audience area, guide the players and block irrelevant people and vehicles, and the road needs to be quickly restored for traffic after the event, reducing the interference with urban traffic.

[0003] However, the fixedly installed guardrails are difficult to disassemble and assemble. The installation structure is complicated, professional construction tools and a large amount of manpower are needed, and it is time-consuming and laborious to disassemble, so that large-scale disassembly and assembly cannot be completed in a short period of time. This not only increases the time cost of event preparation and ending, but also greatly affects the surrounding traffic and residents' life due to the long construction period. Moreover, repeated disassembly and assembly may damage the structure of the guardrails and the road infrastructure. For example, the welding part may crack and deform after repeated disassembly and assembly, reducing the safety and service life of the guardrail. The deeply embedded and fixed guardrail may also damage the integrity of the road surface when disassembled, and the subsequent repair work is complicated and costly. Based on the above problems, the present application proposes a road guardrail for marathons to improve the above problems. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims to provide a road guardrail for marathons, which can quickly install the road guardrail through the clamping of the lock ring and the U-shaped ring, improve the efficiency of event preparation, and separate the two road guardrails by moving the pull rod upward when disassembling, so that the road quickly returns to normal traffic.

[0005] The technical scheme adopted by the utility model is as follows:

[0006] A road guardrail for marathons, comprising two bases, a support rod fixed between the two bases, a plurality of horizontal rods fixed inside the support rod, a stand fixed between the plurality of horizontal rods, a lock ring fixed on one side of the support rod, a fixed rod fixed inside the lock ring, a rotating rod rotatably connected to the outside of the fixed rod, a U-shaped ring fixed on the side of the support rod away from the lock ring, and the lock ring and the U-shaped ring being adapted to each other.

[0007] In a preferred embodiment, the upper end of the rotating rod is fixed with a counterweight, and the counterweight is located on the side of the rotating rod away from the supporting rod, and the upper end of the counterweight is fixed with a pull rod.

[0023] Further, the present application will be described in detail with reference to the drawings, in which the same or similar components are denoted by the same reference numerals, and similarly, the sectional view of the device structure is partially enlarged without the general proportion for convenience of explanation, and the schematic diagram is only an example, which should not limit the scope of protection of the present application. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual manufacture.

[0024] Please refer to the accompanying Figures 1 to 3 As shown in the accompanying drawings, the present application provides a road guardrail for marathon, which comprises two bases 10, a supporting rod 11 fixed between the two bases 10, a plurality of crossbars 12 fixed inside the supporting rod 11, a stand 13 fixed between the plurality of crossbars 12, a lock ring 14 fixed on one side of the supporting rod 11, a fixed rod 15 fixed inside the lock ring 14, a rotating rod 16 rotatably connected to the outside of the fixed rod 15, a U-shaped ring 17 fixed on the side of the supporting rod 11 away from the lock ring 14, and the lock ring 14 and the U-shaped ring 17 are matched.

[0025] In this embodiment, when the road guardrails need to be installed, the two road guardrails with the lock ring 14 on one side and the U-shaped ring 17 on the other side are moved close to each other, because the lower end of the outer side of the rotating rod 16 is provided with a slope, when the U-shaped ring 17 of one road guardrail moves to the inside of the lock ring 14, the rotating rod 16 rotates upward around the fixed rod 15 under the action of the U-shaped ring 17, when the U-shaped ring 17 moves to the inside of the lock ring 14, the rotating rod 16 rotates downward around the fixed rod 15 under the action of the counterweight 18, at this time, the U-shaped ring 17 and the lock ring 14 are clamped, when the two road guardrails need to be disassembled, the pull rod 19 is moved upward, the pull rod 19 drives the counterweight 18 and the rotating rod 16 to rotate upward around the fixed rod 15, by moving the U-shaped ring 17, the two road guardrails can be disassembled conveniently and quickly.

[0026] In a preferred embodiment, referring to Figure 3 , the upper end of the rotating rod 16 is fixed with the counterweight 18, and the counterweight 18 is located on the side of the rotating rod 16 away from the support rod 11, and the upper end of the counterweight 18 is fixed with the pull rod 19.

[0027] In this embodiment, the upper end of the lock ring 14 is used to support the counterweight 18, which can keep the rotating rod 16 and the lock ring 14 horizontal, and the pull rod 19 is fixed on the upper end of the counterweight 18, which provides a convenient operating point for the staff.

[0028] Secondly, referring again to Figure 3 , the upper end of the outer side of the pull rod 19 is sleeved with a non-slip rubber sleeve, and the outer side of the non-slip rubber sleeve is uniformly provided with a plurality of non-slip patterns.

[0029] In this embodiment, the non-slip rubber sleeve and the non-slip patterns on the outer side thereof can greatly increase the friction between the staff's hands and the pull rod 19, so that the staff can hold the pull rod 19 more stably, ensuring the accuracy and stability of the operation.

[0030] Thirdly, referring to Figure 1 and Figure 2 , the outer side of the support rod 11 and the upper end of the cross rod 12 are rotatably connected with the support plate 20, and the end of the support plate 20 away from the support rod 11 is provided with a shock pad.

[0031] In this embodiment, when connecting the road guardrails, the support plate 20 and the support rod 11 are perpendicular by rotating the support plate 20, when the athlete accidentally hits the road guardrail and makes it fall down, the shock pad on the support plate 20 can effectively buffer the impact force, reduce the impact force on the athlete, and reduce the risk of injury.

[0032] In order to further understand and illustrate, taking Figure 1 as an example, the outer side of the plurality of vertical columns 13 is provided with a shock plate 21.

[0033] In this embodiment, when the athlete accidentally hits the road guardrail to fall down, the shock-absorbing plate 21 can effectively buffer the impact force generated in this process, and the shock-absorbing plate 21 can make the contact process between the road guardrail and the athlete more soft, and will not cause additional scratches or extrusion injuries to the athlete due to the hard edges or surfaces of the road guardrail.

[0034] In a preferred embodiment, please refer to Figure 1 One end of the shock-absorbing plate 21 is provided with a groove, and the inside of the groove is provided with a reflective sticker 22.

[0035] In this embodiment, the reflective sticker 22 arranged in the groove can provide certain protection for it. Compared with being directly pasted on the surface, the groove can reduce the damage of the reflective sticker 22 caused by external scratches, collisions and the like, prolong the service life of the reflective sticker 22, and reduce the cost of frequent replacement.

[0036] The working principle of the utility model is:

[0037] When it is necessary to install the road guardrail, two road guardrails with a lock ring 14 on one side and a U-shaped ring 17 on the other side are brought close to each other, and the U-shaped ring 17 can push the rotating rod 16 to rotate upward during movement, and when the U-shaped ring 17 no longer moves, the rotating rod 16 rotates downward under the action of the counterweight 18, at this time, the two road guardrails are clamped with each other, and when disassembling, the counterweight 18 and the rotating rod 16 are rotated by moving the pull rod 19 upward, so that the U-shaped ring 17 moves out of the outside of the lock ring 14, so that the two road guardrails can be disassembled, the shock-absorbing pad on the supporting plate 20 and the shock-absorbing plate 21 effectively buffer the impact force, reduce the impact force on the athlete, and reduce the risk of injury.

[0038] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field, unless otherwise specified and limited.
