Description
Technical field
The present invention relates to a kind of self balancing device, especially a kind of mainly being installed on is used for the self balancing device that folding cover is used on the filter lid.
Background technology
At present, the self balancing device that folding cover uses that is used for that generally uses has two kinds, wherein the self balancing device structure used of first kind of folding cover as shown in Figure 1, when the eyebolt on the container top 31 unclamps, rotate internal thread handwheel 32, can not rotate owing to screw rod 33 and lid 31 seam this moment.Can only move upward along the screw axis of rocking arm 34.Rotate rocking arm 34, lid 31 is and then rotated with rocker arm bracket 36 centers by the restriction of limited block 35 together.This moment, lid 31 left container.This device is wasted time and energy when folding cover, and occupation area of equipment is big.
The self balancing device structure that existing second kind of folding cover used as shown in Figure 2, W is the gravity of filter lid 47 among the figure, the handle 48 of opening cover 47, by choosing air spring 42 with suitable elastic force, make lid 47 in opening angle opening angle≤15 ° hour for example, lid gravity W slightly greater than be arranged in the housing 41 spring 42 upward to elastic force, lid 47 can not bounced suddenly because of excessive the making progress of spring 42 power; When lid 47 opening angle 〉=15 ° for example when opening angle is big, lid 47 gravity be slightly less than air spring 42 upward to elastic force, lid 47 can sharply not dropped.
During opening cover 47, be used for up mentioning handle 48, the supporting arm 46 that is connected with lid 47 drives rotating shaft 44 and rotates, connecting rod 3 rotates thereupon, the piston rod of air spring 42 is protruding thereupon, drivening rod 43, rotating shaft 44 and supporting arm 46 rotate in the same way, and lid 47 light fast openings are run into limit body 45 until supporting arm 46.Because the elastic force and the lid gravity of air spring are in state in a basic balance, the strength that hand is used is very little can open the filter lid.With last identical reason, close also light and fast very of filter lid.
This kind structure is because lid gravity and air spring have only an equalization point, and promptly opening angle is located for 85 °, and lid can not be opened excessive.Generally can only opening angle≤85 ° because open near 90 ° when lid, the very big approach infinity of gravity, lid 47 is difficult to close, a bit be in addition lid 47 in opening process, gravity and the air spring power of stretching out is balance everywhere.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of closed cover of openable container very easily is provided, and can be opened into, can both keep the self balancing device of balance in each position everywhere greater than 90 °.

The specific embodiment
As shown in the figure: the upper inside wall at tube-like envelope 1 is provided with fixed mount 18, the top that is located in the elastomeric element 9 in the shell 1 is fixed on the fixed mount 18, can stretch in shell 1 in the bottom of elastomeric element 9, shell 1 internal frame above fixed mount 18 is provided with rotating shaft 3, shell 1 is stretched out in the end of rotating shaft 3, on overhanging section of rotating shaft 3, be provided for driving the rocking arm 19 of lid folding, vertical direction in the shell 1 is provided with drive disk assembly 20, the bottom of drive disk assembly 20 connects the bottom of elastomeric element 9, the top fork 6 of drive disk assembly 20, the other end of fork 6 is fixedlyed connected with rotating shaft 3.Elastomeric element 9 is hollow form, and elastomeric element 9 is socketed in drive disk assembly 20 outsides.
Described drive disk assembly 20 comprises bolt 14 and chain 10, the bottom of bolt 14 is fixed on the briquetting 15, the bottom that on briquetting 15, connects elastomeric element 9, the top of bolt 14 is passed elastomeric element 9 and is utilized chain attaching parts 21 and the bottom that is positioned at the chain 10 of elastomeric element 9 to join, the bottom of chain 10 and chain attaching parts 21 are hinged, the top of chain 10 also is provided with chain attaching parts 21, the chain attaching parts 21 on chain 10 tops are articulated in the bottom of fork 6, and the top of fork 6 utilizes spline to fixedly connected with rotating shaft 3.
Be provided with the jackshaft 7 that relies on mutually with chain 10 on fixed mount 18, be with the lining 8 that high-abrasive material is made outside the jackshaft 7, the axis of bolt 14 passes the outer side edges with respect to the lining 8 of chain 10 1 sides.Rotating shaft 3 two ends are erected on the bearing 4 inwall circumference that are arranged on the shell 1, are provided with spacer 5 in the rotating shaft 3 between fork 6 two sides and the corresponding bearing 4, are provided with plain washer 2 between spacer 5 and bearing 4.Elastomeric element 9 is for being located in the spring in the shell 1.
During use, elastomeric element 9 spring tops are fixed on the fixed mount 18 in the shell 1, the bottom retractable.Outside the rotating shaft 3 that has spline is subjected to before the couple effect, the elastomeric element 9 springs nut 16 that has been lengthened out rotatably compresses, and adjusts briquetting 15 and executes external force and act on elastomeric element 9 springs.Elastomeric element 9 springs have been prepared certain mechanical energy.The effect of locking nut 17 only is used for tightening up, and it is loosening to prevent to add long nut 16.The rotating shaft that has spline 3 that is subjected to outer couple effect by fork 6, chain 10, articulated mast 11, bolt 14, add the effect of long nut 16, briquetting 15, is executed the lower end that external force acts on elastomeric element 9 springs when rotating.At this moment, acting on the moment of torsion that fork 6 countershafts 3 produce to down spring and equating with the moment of torsion that is subjected to lid gravity to act on 3 generations of rocking arm 19 countershafts of elastomeric element 9 springs is in poised state.So when opening lid, only need pull lid gently, make the acting on moment of torsion that fork 6 countershafts 3 produce to down spring and equate that greater than being subjected to lid gravity to act on the moment of torsion that rocking arm 19 countershafts 3 produce lid is opened naturally under the effect of elastomeric element 9 of elastomeric element 9 springs; When closing lid, since lid gravity act on moment of torsion that rocking arm 19 countershafts 3 produce must overcome make elastomeric element 9 springs act on the moment of torsion that fork 6 countershafts 3 produce to down spring, and spring is in the process of being compressed, elastic force is respective change along with the fastening degree of lid, lid can sharply not dropped, only can gently be closed.When lid is buckled, lid gravity act on moment of torsion that rocking arm 19 countershafts 3 produce again with elastomeric element 9 springs to act on the moment of torsion that fork 6 countershafts 3 produce to down spring identical, so the acting on fork 6 countershafts 3 moment of torsion that produces and the moment of torsion that lid gravity acts on 3 generations of rocking arm 19 countershafts to down spring and keep poised state constantly of elastomeric element 9 springs.
