Description

Technical Field

[0001] This utility model belongs to the field of functional decoration technology, specifically, it relates to a combined guardrail for the side roof of a vehicle. Background Technology

[0002] Emergency fire and rescue vehicles all have a cargo compartment for carrying fire extinguishing agents or rescue equipment. Due to different vehicle models, the cargo compartments vary in length (3000mm~10000mm) and height (1800mm~2800mm), and can be divided into two categories: long and short cargo compartments and short and small cargo compartments. The top of the cargo compartment is usually equipped with large equipment such as fire spray cannons, lifting lights, water suction pipes, fire ladders, and fire hooks. The top of the fire extinguishing agent tanker also has fire extinguishing agent filling ports, maintenance ports, and liquid level gauge installation holes. Emergency rescue personnel will go up to the roof to operate or retrieve equipment in the fire rescue battlefield or training site. Cargo compartment maintenance and repair will also be carried out on the roof. According to the national fire truck standard requirements: (1) Safety railings should be provided on both sides of the cargo compartment of emergency fire and rescue vehicles; (2) Fire warning red flashing lights, outer lighting lights, inner lighting lights, and front and rear indicator lights should also be installed on the railings of the cargo compartment.

[0003] Currently, most emergency rescue vehicles use aluminum alloy profiles for their side roof safety railings. However, different manufacturers use different profile structures and shapes, employing the same structure and size for both long and short vehicles. This use of the same fixed structure and size for both railings and red strobe lights makes it difficult to achieve the desired overall harmony. If a profile and strobe light are well-coordinated with the overall shape of a long vehicle, they will appear too large on a short vehicle, resulting in a disproportionate appearance. Similarly, if they are well-coordinated with the overall shape of a short vehicle, they will appear too small on a long vehicle, also leading to a disproportionate appearance. Furthermore, using a single profile for the side roof railing also presents several drawbacks. (1) When a person stands on the roof of the car and needs to hold the guardrail, the grip strength is not optimal, and there is a feeling of not being able to hold it tightly, which gives people a lack of security. (2) When there are objects that need to be temporarily tied to the guardrail on the roof surface, there is no place on the profile guardrail for ropes to be tied. (3) The same emergency rescue vehicle manufacturer uses one type of guardrail profile to assemble all sizes of vehicles, and the strobe lights can only be selected in one size, which makes the structure and shape too monotonous and cannot well reflect the coordination of the different lengths and sizes of the carriages and the diversity of the products.

[0004] Therefore, the desired safety railing for the side roof of emergency rescue vehicle compartments is a modular railing solution that is suitable for both long and short compartments, while maintaining an overall harmonious and aesthetically pleasing appearance.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0006] Therefore, in order to solve the above problems, this utility model provides a combined guardrail for the side roof of a vehicle compartment. Utility Model Content
