Fire extinguisher cabinet capable of being rapidly opened on basis of lever principle

Abstract

The invention relates to the technical field of fire-fighting and discloses a fire extinguisher cabinet capable of being rapidly opened on the basis of the lever principle. The fire extinguisher cabinet comprises a bottom plate; a shell is fixedly connected to the upper portion of the bottom plate; a fulcrum is fixedly connected into the shell; and a small spring is movably connected to the upperportion of the bottom plate. A user puts one foot on a pedal to stamp down the pedal, the left end of a transverse rod cocks through the lever principle, an upper cover is rapidly opened, and thus theopening mode of the fire extinguisher cabinet is simpler; meanwhile a sliding block moves upwards, a toothed bar moves upwards synchronously, the front surface of the toothed bar is movably connectedwith a gear, the gear rotates, thus a rotary rod rotates, a supporting plate ascends, large springs are movably connected with the two sides of the supporting plate, the large springs expand outwardsduring ascending, and the action of the force is reduced; meanwhile a fire extinguishing bottle is movably connected to the upper portion of the supporting plate, thus the fire extinguishing bottle ascends synchronously, the user can take out the fire extinguishing bottle without bending down, thus the fire extinguishing bottle can be taken out with less effort in shorter time, the working efficiency is improved, and the rescue time is prolonged.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire extinguisher box that can be quickly opened based on the principle of leverage. Background technique [0002] Firefighting work refers to the general term for the work to eliminate danger and prevent disasters. The firefighting work in my country is mainly based on prevention and the combination of prevention and fire prevention. Therefore, relevant equipment will be equipped in all major venues in case of emergency. The fire generally spreads quickly, and the corresponding fire extinguishing equipment needs to be taken out in time to eliminate hidden dangers. Therefore, when a fire needs emergency treatment, time control is particularly important. [0003] Among the related fire extinguishing equipment, portable fire extinguishers are the most common, and portable fire extinguishers are generally placed in fire extinguisher boxes, which are necessary fire extinguis...

AI Technical Summary

Problems solved by technology

[0003] Among the related fire extinguishing equipment, portable fire extinguishers are the most common, and portable fire extinguishers are generally placed in fire extinguisher boxes, which are necessary fire extinguishing equipment for shopping malls, office buildings, stations and other places. The traditional fire extinguisher boxes are divided into door opening room and There are two types of clamshell type, which are generally placed on the ground. When a fire occurs and the fire extinguisher needs to be removed, the operator needs to squat down first, then open the lid of the fire extinguisher box, then reach out to take out the fire extinguisher, and finally squat up, squat down and squat up again The process will be delayed for a period of time, and in an emergency, they will generally run to the side of the box. Emergency squatting and standing will make the blood rise, which will easily cause dizziness and other discomfort. Due to time constraints, it may eventually lead to missing the best time for fire rescue , causing irreversible consequences
