Overturning type guardrail and vehicle

Abstract

The invention discloses an overturning type guardrail. The overturning type guardrail comprises a guardrail support, a guardrail frame assembly and limit pieces, wherein one end of the guardrail support is detachably fixed onto on side surface of a vehicle, and the other end of the guardrail support is provided with first limiting holes; the guardrail frame assembly comprises guardrail support legs and guardrail rods; one end of every guardrail support leg is provided with a second limiting hole and a third limiting hole and rotatably connected with the guardrail support through a rotating shaft, the distances between the rotating shaft and the first limiting holes, the second limiting holes as well as the third limiting holes are identical; an elastic device is arranged between the guardrail support legs and the guardrail support; each limit piece is used for matching with the corresponding first limiting hole, and one of the corresponding second limiting hole and the corresponding third limiting hole. The overturning type guardrail is simple in structure and easy to manufacture and use, no matter when turning upwards or downwards, can be limited through the limit pieces to stably maintain an upwards-tilted state or a downwards-retracted state and can avoid automatic downward turning due to vibration, thereby reducing potential risks. The invention also discloses the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to a rollover guardrail and a vehicle. Background technique [0002] Freight vehicles are generally larger in size and have a higher chassis. Therefore, in order to prevent the small vehicle from getting into the bottom of the freight vehicle when it collides with a small vehicle, and to protect the various components installed on the chassis of the freight vehicle, it is usually placed on both sides of the body. And install the guardrail on the rear side. When a freight vehicle breaks down during transportation and cannot reach the maintenance factory for maintenance, it is necessary to repair the vehicle on site, such as the maintenance of the sewage plug, the maintenance of the chassis, etc., but in order to achieve a better protection effect, The distance between the guardrail and other accessories of the vehicle body is usually small, making it difficult for mainte...

Problems solved by technology

When a freight vehicle breaks down during transportation and cannot reach the maintenance factory for maintenance, it is necessary to repair the vehicle on site, such as the maintenance of the sewage plug, the maintenance of the chassis, etc., but in order to achieve a better protection effect, The distance between the guardrail and other accessories of the car body is usually small, which makes it difficult for maintenance personnel to reach the maintenance position, causing great inconvenience to the maintenance personnel. In order to solve this problem, a reversible guardrail has appeared

[0003] In the prior art, patent 201220490562 discloses an easily detachable and reversible guardrail, please refer to figure 1 , figure 1 It is a structural schematic diagram of an easily detachable and reversible guardrail provided in the prior art, including a fixing part 1, a concave lug 2, a guard rail frame 3, a magnet 4, a rotating shaft 5, and a nut 6. The fixing part 1 is installed on the chassis car On the frame, the guardrail frame 3 is located on both sides of the chassis frame, the inner side of the upper beam of the guardrail frame 3 is fixed with concave lugs 2, and there are through holes on the two concave lugs 2, the fixing part 1 and the guardrail frame 3 The concave lugs 2 on the top are connected by the rotating shaft 5, and the two magnets 4 are respectively fixed on the inner side of the lower crossbeam of the guardrail frame 3. When the guardrail frame 3 turns upwards around the rotating shaft 5, it is stuck on the upper end of the fixing part 1 by more than 180°, and the guardrail The frame 3 is fixedly connected with the magnet 4 when it is turned downwards. The structure of the fixing part 1 in this kind of flipped guardrail is relatively complicated, which increases the difficulty of manufacturing. Relying on the fixing part 1, it is easy to be resonated by passing vehicles, causing the protective fence frame 3 to turn downward by itself, threatening the maintenance personnel who are doing maintenance work and causing safety hazards
