Specific embodiment
Following embodiment only exists in illustrative purpose, limits the scope of the invention without being intended to.
Embodiment one:
Referring to Fig.1-2, a kind of apparatus for placing of overturning-preventing, including placement rack 1, the inside of placement rack 1 offer cavity 2,
The interior bottom of cavity 2 is fixed there are two air bag 3, and each air bag 3 is all made of hard plastics and is made, and avoids the variation because of gas
So that the volume of air bag 3 is changed, piston 5 is slidably connected on the inner wall of each air bag 3, the upper side wall of each piston 5 is equal
It is fixedly connected with mobile bar 6, the inner roof wall of upper side wall and cavity 2 that air bag 3 is run through in the upper end of two mobile bars 6, which extends to, to be put
The upper side wall of seat 1 is set, the lower wall of each air bag 3 is respectively and fixedly provided with sucker 4, and setting sucker 4 is placed convenient for sucker 4 and placement rack 1
Sucking between face, and then complete placement rack 1 and suck fixation, each sucker 4 is connected to the inside of air bag 3, placement rack 1
Lower wall is opened up there are two the port that matches with 4 size position of sucker, and the downside of each sucker 4, which both passes through port and extends to, puts
The outside of seat 1 is set, the progress of work is conveniently sucked.
The upper end common rotation of two mobile bars 6 is connected with connecting plate 7, and object is placed on connecting plate 7 and is fixed, object
When the trend that body is toppled over, connecting plate 7 is tilted to side, and the other side of connecting plate 7 pulls mobile bar 6 up to move, piston 5
It is up slided in air bag 3, the air in sucker 4 is up twitched, and the air pressure in sucker 4 reduces, and sucker 4 is made to be adsorbed on set-down location
Surface on, and then offset by tilting force of the adsorption capacity of sucker 4 to 1 this side of placement rack, it is therefore prevented that placement rack 1 inclines
, the process of medical fluid is drawn similar to syringe common in life: during drawing medical fluid, when being pulled outwardly piston,
Only small part of gas volume becomes larger in needle tubing, and air pressure reduces, and external atmosphere pressure is constant, and medical fluid is pressed into needle by atmospheric pressure
In pipe.
Multiple compressed springs 15, setting compression are fixedly connected between the lower wall of connecting plate 7 and the upper side wall of placement rack 1
Spring 15 shakes when avoiding connecting plate 7 by external shock convenient for offsetting to the shaking force on connecting plate 7, influences to put
The stability for the object set.
Connecting plate 7 is equipped with clamping device, and clamping device includes the mounting groove 13 offered in 7 upper side wall of connecting plate, peace
It is slidably connected in tankage 13 there are two grip block 11, offers limiting slot 14, each clamping on the two sides inner wall of mounting groove 13
The both ends of plate 11 all extend in limiting slot 14 and are slidably connected with the inner wall of limiting slot 14, and limiting slot 14 is arranged to grip block 11
It is limited, prevents grip block 11 to be detached from mounting groove 13, be bonded with rubber layer on the side wall of two 11 opposite sides of grip block,
Multiple rubber bumps are evenly distributed on the opposite side side wall of two square rubber layers, rubber layer is set and rubber bumps increase
The frictional force of the object junction of grip block 11 and clamping, prevents object from slipping away, ensure that the stability of clamping.
Offer the screw thread mouth being connected to inside mounting groove 13 on the two sides side wall of connecting plate 7, in each screw thread mouth
It is threaded with bolt 12, each bolt 12 is located at one end in mounting groove 13 with one of grip block 11 far from another
The side side wall of grip block 11 is in contact, and the object of pending fixation is placed in mounting groove 13, by bolt 12 in screw thread mouth
Interior screw-in pushes grip block 11 toward medial movement, is gripped by two grip blocks 11 to object.
Anti-moving mechanism is equipped in cavity 2, anti-moving mechanism includes the fixed plate 9 being fixedly connected with 2 inner wall of cavity, fixed plate 9
Two sides be fixedly connected to reservoir 10, the inside of two reservoirs 10 is filled with magnetorheological fluid, and magnetorheological fluid belongs to controllable
Fluid is that more active one is studied in intellectual material, and magnetorheological fluid is by high magnetic permeability, low hysteresis small soft magnetism
The suspended substance that particle and non-magnetic liquid mix, this suspended substance show low viscosity, Gao Liu under zero magnetic field condition
The Newtonian fluid characteristic of dynamic property;And under strong magnetic field action, then high viscosity, the characteristic of low-flow are showed, and magnetorheological
Rheology of the liquid under magnetic fields be moment, reversible, and it has stable corresponding relationship with magnetic field strength, therefore is
A kind of widely used, function admirable intellectual material.
The middle part of each reservoir 10 offers socket, and the diameter of socket is slightly less than the diameter of movable plate 6, each movement
Bar 6 both passes through socket far from one end of air bag 3, and the first magnet 8, each first magnetic are arranged on the outer wall of each mobile bar 6
Iron 8 is respectively positioned on the downside of reservoir 10, and when beginning mobile bar 6 moves up, squeezing magnetorheological fluid, side is flowed outward, when the object of clamping
When the trend toppled over, connecting plate 7 is tilted to side, when the other side of connecting plate 7 pulls mobile bar 6 up to move, first
Magnet 8 is mobile toward the side of reservoir 10, changes magnetorheological fluid from fluid to solid, is clamped to mobile bar 6, prevents from moving
Lever 6 moves up, and avoids the increasing of slope trend.
Embodiment two:
Referring to Fig. 3, anti-moving mechanism includes the fixed plate 9 being fixedly connected with 2 inner wall of cavity, and the two sides of fixed plate 9 are fixed
It is connected with the second magnet 16, sliding mouth is offered on each second magnet 16, each cunning mouth is big with one of mobile bar 6
Small position matches, and the upper end of each mobile bar 6 both passes through sliding mouth and is slidably connected with the inner wall of sliding mouth, each mobile bar 6
The first magnet 8 is arranged on outer wall, each first magnet 8 is respectively positioned on the downside of the second magnet 16, the first magnet 8 and the second magnetic
The magnetism of iron 16 is on the contrary, when the trend that the object of clamping is toppled over, and connecting plate 7 is tilted to side, the other side of connecting plate 7
When mobile bar 6 being pulled up to move, the first magnet 8 is mobile toward the side of the second magnet 16, by the second magnet 16 to the first magnetic
The repulsion of iron 8 hinders mobile bar 6 to move up, avoids the increasing of slope trend.
It further illustrates, it is above-mentioned to be fixedly connected unless specifically defined or limited otherwise, otherwise to shall be understood in a broad sense, example
Such as, it can be welding, be also possible to gluing, or be integrally formed the customary means well known to those skilled in the art such as setting.
Although be used more herein placement rack 1, cavity 2, air bag 3, sucker 4, piston 5, mobile bar 6, connecting plate 7,
First magnet 8, fixed plate 9, reservoir 10, grip block 11, bolt 12, mounting groove 13, limiting slot 14, compressed spring 15, second
The terms such as magnet 16, but it does not exclude the possibility of using other terms.The use of these items is only for more easily retouch
State and explain essence of the invention;Being construed as any additional limitation is disagreed with spirit of that invention.
