Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a rescue cart used for fire fighting. Background Art

[0002] The most common fire-fighting equipment are fire extinguishers and air breathing apparatus cylinders. Fire-fighting air breathing apparatus cylinders are important equipment used by firefighters to rescue fire scenes and other emergency situations during firefighting operations. The design of this type of air breathing apparatus cylinder pays more attention to the safety and heat resistance of the structure. Its surface is usually covered with a layer of special high-temperature resistant material to prevent the risk of explosion that may occur in the fire scene. At the fire scene, due to the presence of smoke and toxic gases, firefighters may face the risk of difficulty breathing or even suffocation. Fire-fighting air breathing apparatus cylinders can provide firefighters with clean air in a timely manner, ensuring that they can breathe normally in harsh environments such as high temperature, smoke and dust, and successfully complete the rescue work.

[0003] The Chinese patent with the authorization announcement number CN213642931U discloses a fire-fighting cart. Through the fire-fighting nozzle storage box arranged at the bottom of the cart body, the fire-fighting nozzle can be stored and hidden by using the mutual rotation cooperation of the manual turntable and the winding disk when the nozzle is idle. This can not only effectively improve the working efficiency of the fire-fighting nozzle storage and avoid the entanglement and knotting of the fire-fighting nozzle, which affects the normal use of the fire-fighting operation, but also effectively avoid the aging and damage of the fire-fighting nozzle caused by long-term light oxidation through hidden storage, thereby extending the service life of the fire-fighting nozzle;

[0004] However, the above device still has some defects when in use. Although it can transport fire extinguishers, some larger fire extinguishers still need to be moved between the cart body and the fixed frame by manpower. The whole operation process increases the labor intensity of the operator, and it is not convenient to quickly place the large fire extinguisher inside the cart for transfer. Therefore, a rescue cart for firefighting is proposed to solve the above problems. Utility Model Content
