Background technology
As everyone knows, when earthquake occured, building or building walls, ceiling can collapse because of the violent earthquake fluctuation, with furniture compression failures such as tables and chairs, bed cabinets, if the people hides therein, are not best mode though there is escape to wish, the escape chance is very little.So far, relatively less about the device product of earthquake escape rescue on the market, and also mostly highly professional, be generally rescue group, fire brigade's equipment configurations, and not in conjunction with daily life, enter common people house.
Disclose a kind of earthquake protective bed in the patent 201020272041, this earthquake protective bed principle is provided with arch security protection top above bed, and dress is received in the storing bin of the head of a bed at ordinary times.Side guidance is provided with telescopic supporting pin in the biside plate of bed, and the above can place mattress, and when sending out earthquake, automatic switch makes supporting pin to reclaiming contracting, and mattress glides along guide groove, touches bed end device, will fold the protection top and pull out, and forms arch security protection top.This guard bed when shrinking the frictional force of its supporting pin larger, and whole folding protection top also takies significant volume, complicated structure when receiving dress.
The utility model content
Weak point for fear of the prior art existence, especially the protector volume that takes up room is large, complicated structure, the flexible frictional force of folding and unfolding is difficult for the problem of elimination during use, the utility model proposes a kind of active earthquake protective bed, by the deformable sidebar structure of utilizing its four-bar linkage and cylinder to drive, make guard bed have simple in structure, safe and reliable, simple operation, with the perfect characteristics that merge of domestic environment.
The technical scheme that its technical problem that solves the utility model adopts is: earthquake protective bed is comprised of headstock, bed body and the single-chip microcomputer, vibrating sensor, the gas cylinder that are installed in the headstock housing, and a bed body also comprises hurdle, top, head of a bed hurdle, Elastic steel cable, cross spacing pipe, longitudinal spacing pipe, bed body base, spring tapered end, cylinder, sidebar lower shaft, stopper slot, tailstock hurdle bottom girder, tailstock hurdle, sidebar draw-in groove, expansion link, four-bar mechanism, shift knob, sidebar back timber; Headstock is fixedly connected with the bed body; The vibrating sensor, the single-chip microcomputer that are provided with on the headstock housing in shift knob and the casing are connected, and single-chip microcomputer is connected with gas cylinder by control device and communicates, and gas cylinder links to each other by the air inlet of conduit with bed side sidebar upper cylinder; Vibrating sensor, single-chip microcomputer form signal receiving unit.
Fixed installation head of a bed hurdle bottom girder and tailstock hurdle bottom girder on the described bed body base, head of a bed field is between head of a bed hurdle bottom girder and hurdle, top, and the longitudinal spacing pipe is fixedly mounted on the head of a bed hurdle bottom girder; The tailstock hurdle is connected with tailstock hurdle bottom girder and hurdle, top respectively, both sides, the tailstock hurdle fixed installation longitudinal spacing pipe on the tailstock hurdle bottom girder; The cross spacing pipe is fixedly mounted on the expansion link at sidebar two ends, side, and the bedside rails support column is provided with stopper slot;
The sidebar of described bed body is divided into left side sidebar and right side sidebar, left side sidebar back timber is provided with C type sidebar draw-in groove, be provided with the sidebar lower shaft in left side sidebar bottom girder and the right side sidebar bottom girder, the back timber of both sides sidebar and the middle part of lower shaft are provided with cylinder, cylinder both sides between sidebar back timber and the sidebar lower shaft fixedly mount the identical expansion link of some structures, mounting spring tapered end on the expansion link, when cylinder and expansion link elongation, the both sides sidebar rotates around the sidebar lower shaft, longitudinal spacing pipe and cross spacing pipe support close spacing mutually, left side sidebar draw-in groove and right side sidebar back timber tighten mutually, and expansion link upper spring tapered end is automatically locked; Sidebar lower shaft two ends are connected with head of a bed hurdle bottom girder and tailstock hurdle bottom girder respectively.
Described four-bar mechanism is hinge engaging structure, and four four-bar mechanisms are positioned at a body four ends; One end of each four-bar mechanism is connected with the hurdle, top respectively, and the other end of each four-bar mechanism is connected with bottom girder two ends, head of a bed hurdle and bottom girder two ends, tailstock hurdle respectively; Elastic steel cable is connected in each end of both sides sidebar back timber, and the Elastic steel cable other end is connected on the connecting rod of each four-bar mechanism; Elastic steel cable pulling four-bar mechanism outwards departs from the dead-centre position.
Operation principle of the present utility model: when earthquake was arrived, the receiver module that is positioned at headstock housing received the signal of seismic network; Perhaps manual triggers is positioned at the mechanical switch on the headstock housing, or by vibrating sensor detection seismic signal, thereby the Single-chip Controlling operating circuit is closed, and the gas cylinder that is positioned at the head of a bed begins to inflate to cylinder by conduit, and the both sides sidebar trails rapidly under cylinder and expansion link drive.Simultaneously, both sides sidebar back timber pulling Elastic steel cable, steel cable also drives four-bar mechanism motion under the bed board, makes it outwards depart from the dead-centre position, and then the hurdle, top of bed board made loses constraint, and bed board falls in the bed together with the people simultaneously.Because opposite force, steel cable drives the dual-side hurdle inwardly topples over around lower shaft, and after cylinder stretched and reaches the precalculated position, longitudinal spacing pipe and cross spacing pipe support closed spacing mutually, left side sidebar draw-in groove and right side sidebar back timber tighten mutually, and expansion link upper spring tapered end is automatically locked; The synthetic triangular prism shape of left side sidebar draw-in groove and right side sidebar back timber frame forms the guard space with suitable bearing capacity; The bed body deformability is finished and be need not the air pressure support, and gas cylinder stops inflation.Bed body bottom welding has two triangle bed body bases, the situation generation that can avoid making because of building collapse people and bed board to drop out under the bed body.
Beneficial effect
The active earthquake protective bed of the utility model, headstock is fixedly connected with the bed body; Be provided with shift knob at headstock housing, vibrating sensor and single-chip microcomputer in the casing connect to form signal receiving unit; Single-chip microcomputer is connected with gas cylinder by control device and communicates, and gas cylinder links to each other by the air inlet of conduit with bed side sidebar upper cylinder; The guard bed deformable sidebar structure of utilizing four-bar linkage and cylinder to drive, frame closes has the strong guard space of bearing capacity simple in structure.Guard bed with cylinder as dynamical element, make a physical efficiency finish rapidly distortion; The bed body supports and crushed element is four-bar mechanism, and reliability is high; In bed body and headstock housing, reserve multiple triggering control interface, receive signal by receiving system, both can manually control, also can be from dynamic shake, the maltilevel security insurance, reliability is high.
