Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1-4, a fire extinguisher box capable of being opened quickly based on lever principle, comprising a bottom plate 1, two bases fixedly connected below the bottom plate 1, the two bases have the same size and lower height, and the two bases are symmetrically distributed by taking the central line of the shell 2 as the reference, so that the center of the fire extinguisher box is eccentric, and the fire extinguisher box is more stable, the shell 2 is fixedly connected above the bottom plate 1, the inner part of the shell 2 is fixedly connected with a fulcrum 3, the distance from the fulcrum 3 to a pedal 9 is less than the distance from the fulcrum 3 to the left side of the shell 2, so that when the pedal 9 is stepped down, the moving distance of a rack 14 is larger, a gear 15 rotates faster, finally, the opening angle of an upper cover 8 is larger, and the ascending distance of a fire extinguisher bottle 17 is.

Bottom plate 1's top swing joint has little spring 4, initial position can be resumeed when loosening footboard 9, the inboard swing joint of fulcrum 3 has horizontal pole 5, the top of 5 left sides ends of horizontal pole articulates there is montant 6, the outside fixedly connected with fixing base 7 of montant 6, the top swing joint of fixing base 7 has upper cover 8, the size of upper cover 8 is not less than shell 2's size, make the lock inseparabler, one side swing joint that montant 6 was kept away from to horizontal pole 5 has footboard 9, the top swing joint of bottom plate 1 has down tube 10, the top swing joint of down tube 10 has backup pad 11, the equal swing joint in both sides of backup pad 11 has big spring, big spring is in compression state when the case of putting out a fire is closed, convert the elastic potential energy of spring into ascending thrust, make backup pad 11 more laborsaving when ascending, thereby it is more.

The top swing joint of backup pad 11 has spacing frame, spacing frame highly be not less than in the half height of fire bottle 17, and spacing frame's width is not less than two fire bottle 17's width, position to fire bottle 17 carries on spacingly, prevent that fire bottle 17 from taking place to rock at the in-process that rises, take place to empty, bottom plate 1's top fixedly connected with limiting plate 12, the spout has been seted up to limiting plate 12's inside, the size of spout is not less than slider 13's size, reduce the frictional force that slider 13 slided the production in limiting plate 12, the inside swing joint of limiting plate 12 has slider 13, slider 13's positive swing joint has ratch 14, ratch 14's positive swing joint has gear 15, gear 15's inside swing joint has bull stick 16, backup pad 11's top swing joint has fire bottle 17.

The working principle is as follows: the pedal 9 is pressed downwards by putting feet above the pedal 9, the left side of the pedal 9 is movably connected with a cross rod 5, the cross rod 5 can be pressed downwards, the outer side of the cross rod 5 is fixedly connected with a fulcrum 3, the left end of the cross rod 5 is upwards tilted under the matching of the pressure and the fulcrum 3 by the cross rod 5 which is pressed, one end of the cross rod 5, which is far away from the pedal 9, is hinged with a vertical rod 6, the vertical rod 6 can be upwards pushed when the left end of the cross rod 5 is tilted upwards, the upper cover 8 is movably connected above the vertical rod 6, the upper cover 8 is hinged with the shell 2 through a fixing seat 7, the upper cover 8 can rotate by taking the hinged part as a rotating point, the upper cover 8 is opened, meanwhile, when the cross rod 5 is tilted upwards with the fulcrum 3, the cross rod 5 is movably connected with a sliding block 13, and the sliding block 13 is positioned inside the limiting plate 12, the event can make slider 13 up remove, the positive swing joint of slider 13 has ratch 14, so ratch 14 can be along with slider 13's removal and up move, ratch 14's positive swing joint has gear 15, so when ratch 14 up moves, can make gear 15 take place rotatoryly, gear 15's inside swing joint has bull stick 16, so bull stick 16 begins to rotate, bull stick 16's surface is equipped with the screw thread, the effect of cooperation down tube, thereby make the high rising of backup pad 11, simultaneously backup pad 11's both sides swing joint has big spring, big spring outwards expands when rising, the effect of reducing power, the top swing joint of backup pad 11 has fire bottle 17, so make fire bottle 17 can rise with the step, thereby make taking out of fire bottle 17 convenient and fast more, and high speed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
