Abstract

The invention relates to an analysis device, wherein, a cover open and close keeping mechanism is provided. The cover open and close keeping mechanism consists of at least one spring cam hinge which is equipped with a cam mechanism that generates force for keeping the open and close status of a cover and a spring and a friction hinge which generates the friction resistance for keeping the status of the friction hinge at the whole cover open and close position. When the cover is open, the auxiliary force generates from the elastic force of the spring. When the cover is closed, the spring force and the friction resistance can prevent the cover from falling. During the opening and the closing of the cover and in view of the turning force of the spring cam hinge caused by the cam mechanism, the action of the cover can be prevented from changing dramatically through the friction hinge. Therefore, the opening action and the closing action can be smoothly implemented.

Following with reference to accompanying drawing 4~11 explanation embodiments of the invention 2.
The lid open-close maintaining body 14 of present embodiment as shown in Figure 4, at casing 2 with cover between the lid 3 of its front, is made of spring cam hinge 15 and friction hinge 16.
Described spring cam hinge 15 as shown in Figure 5, is made of spindle unit 15a, the 1st cam 15b, the 2nd cam 15c, spring 15d and their housing 15e of folding and unfolding.Both ends 15k, the 15k of the spindle unit 15a described later that protrudes from housing 15e are fixed on the lid 3, and housing 15e is fixed on the casing 2.
As Fig. 6 and shown in Figure 7, described spindle unit 15a has the rotation axis that becomes center of rotation, is used to be erected between end walls 15j, the 15j of housing 15e, it has end walls 15j, the long length in the interval between the 15j than housing 15e, and both ends 15k, 15k protrude from housing 15e.Described the 1st cam 15b is arranged on integratedly and connects described housing 15e inside, on the periphery of the spindle unit 15a that sets up rotationally.Described the 2nd cam 15c is the periphery of the part that is positioned at housing 15e of this spindle unit 15a, and is free to rotate and axially to be nested in spindle unit 15a movably outer and be provided with the part that keeps rotating halted state on housing 15e.Described spring 15d compression is connected between the outer end that is embedded in the 2nd cam 15c on the spindle unit 15a and housing 15e, and described the 1st cam 15b and described the 2nd cam 15c are applied elastic force always.In addition, on the crimping face of described the 1st cam 15b and the 2nd cam 15c, on described the 1st cam 15b at peripheral direction interconnected 2 protuberance 15f, 15f (mountain) be in the shape of the letter V therebetween recess 15g, 15g (paddy) recessed, in addition, also at peripheral direction interconnected 2 protuberance 15h, 15h be in the shape of the letter V therebetween recess 15i, 15i recessed, both protuberances and recess are meshing with each other on described the 2nd cam 15c.
By protuberance and the recess engagement of described the 1st cam 15b and the 2nd cam 15c, keep the release position and the locked position of coupler of lid 3.The release position of lid 3 is that the angle between casing 2 and the lid 3 for example is the position less than 90 degree, two cam 15b, 15c, and protuberance and recess are meshing with each other under this state.The locked position of coupler of lid 3, the angle between casing 2 and the lid 3 are the position of 0 degree, two cam 15b, 15c, and protuberance and recess are meshing with each other under this state.
When with described lid 3 from opening into locking or when being latched to the release position and starting, the 1st cam 15b rotates with spindle unit 15a, because this rotates, on the protuberance and the dip plane between the recess of two cam 15b, 15c, spring 15d crimping the 1st cam 15b and the 2nd cam 15c.Before the convex surface 15h of the convex surface 15f of the 1st cam 15b through the 2nd cam 15c, because of the elastic force of spring 15d, the convex surface 15f of the 1st cam 15b, to original state under the direction of recess 15i engagement of the 2nd cam 15c move.In addition, when with described lid 3 from opening into locking or when being latched to open position and beginning further to start, the convex surface 15f of the 1st cam 15b is by the convex surface 15h of the 2nd cam 15c, because the elastic force of spring 15d, the convex surface 15f of the 1st cam 15b moves to the direction with the recess 15i engagement of the 2nd cam 15c of adjacency.
Described friction hinge 16 as shown in Figure 5, is made of spindle unit 16a and axle rotating bearing component 16b.Both ends 16d, the 16d of spindle unit 16a described later is fixed on the lid 3, and housing 16f described later is fixed on the casing 2.Described spindle unit 16a has the rotation axis that becomes center of rotation, by constituting with the large-diameter portion 16c of axle rotating bearing component 16b joining part and both ends 16d, the 16d littler than the diameter of large-diameter portion 16c.The large-diameter portion 16c of described spindle unit 16a has carried out surface working in advance on the rotation axis surface.Described spindle unit 16a has the length longer than axle rotating bearing component 16b, and the both ends 16d of spindle unit protrudes from the two ends of axle rotating bearing component 16b.Described axle rotating bearing component 16b encases rotation axis, by rotation axis ground free to rotate supporting shaft part 16a.Described axle rotating bearing component 16b is made of resin parts 16e and housing 16f.Resin parts 16e has constituted the face that joins with spindle unit 16a.Housing 16f is in the integrally formed formation in the outside of resin parts 16e.
Integrally formed processing is by on the housing 16f in being pre-configured in the mould of high temperature, clamp-ons the integrally formed grade of pressing mold of resin parts 16e and carries out.Therefore, integrally formed after, when the temperature of housing 16f and resin parts 16e reduced, resin parts 16e shrank, and produced the stress and the housing 16f that tighten and was adjacent to.
Implemented surface working on the surface of the rotation axis of spindle unit 16a in advance, for example, when surface accuracy is 0.18 μ m, have as shown in Figure 8 angle of rotation and the relation between the moment.Therefore, because the constrictive force that the shaping of resin parts 16e is shunk is close to the axle rotating bearing component 16b on the spindle unit 16a, produce frictional resistance for the rotating force of spindle unit 16a on the face being close to, when spindle unit 16a is subjected to bigger rotating torque for the frictional resistance of axle rotating bearing component 16b from the outside, spindle unit 16a will relatively rotate with respect to axle rotating bearing component 16b, and will can not rotate, thereby can maintain on any rotational angle by frictional resistance for the rotating torque littler than frictional resistance.
Lid open-close maintaining body 14, constitute by described spring cam hinge 15 and described friction hinge 16, if if lid 3 from reach locking or from the position that is latched to out to start distance be 100% o'clock, open and close between about 30~70% in the way at it, in order to go up the posture that keeps lid 3 at an arbitrary position, carry out the adjustment of spring 15d for spring cam hinge 15, and carry out the surface working of spindle unit 16a, thereby the power that the frictional resistance that makes friction hinge 16 is produced greater than the spring 15d by spring cam hinge 15 and the deadweight of lid 3 for friction hinge 16.On the other hand, above-mentioned interval in addition in opening and closing the way, generation is to the auxiliary force of the switching of lid 3, and in order to make the switching action level and smooth, carry out the adjustment of spring 15d for spring cam hinge 15, and carry out the surface working of spindle unit 16a, thereby the power that the frictional resistance that makes friction hinge 16 is produced less than the spring 15d by spring cam hinge 15 and the deadweight of lid 3 for friction hinge 16.
As mentioned above, according to the lid open-close maintaining body 14 of present embodiment, under open state, shown in Fig. 9 (A), the power generation effect that spring cam hinge 15 and friction hinge 16 are produced.That is, in spring cam hinge 15, the 1st cam 15b and the 2nd the concavo-convex of cam 15c are meshed, and the power generation effect of spring 15d produces the power of lid 3 to the direction of opening that allows.Compare when the deadweight of lid 3 is heavier with this power, lid 3 will be closed.But, because friction hinge 16, generation and the opposite friction force of lid 3 closing directions, thereby can allow lid 3 keep open states.
In addition, under blocking, shown in Fig. 9 (B), the power generation effect that spring cam hinge 15 is produced.That is, in spring cam hinge 15, the 1st cam 15b and the 2nd the concavo-convex of cam 15c are meshed, because the effect of the power of spring 15d, produce the power of the direction that lid 3 closes of allowing, and can allow lid 3 remain under the blocking.For this reason, lid 3 can not opened.
When uncap 3, shown in Fig. 9 (C), the power generation effect that spring cam hinge 15 and friction hinge 16 are produced.Promptly, in spring cam hinge 15, the 1st cam 15b and the 2nd the concavo-convex of cam 15c are not meshing with each other, the 2nd cam 15c that produces because of spring 15d is by the crimping setting of the 1st cam 15b, make its on arbitrarily angled because the power of spring 15d produces the power to engagement direction upset (locking → open direction) as auxiliary force.Like this, spring cam hinge 15 produces the power of uncaps 3 directions, when this force rate lid 3 from important when big, lid 3 can be opened.But, because friction hinge 16 generations and uncap 3 rightabout friction force, thereby the posture of maintenance lid 3.
When close cap 3, shown in Fig. 9 (D), the power generation effect that spring cam hinge 15 and friction hinge 16 are produced.Promptly, in spring cam hinge 15, the 1st cam 15b and the 2nd the concavo-convex of cam 15c are not meshing with each other, the 2nd cam 15c that produces because of spring 15d is by the crimping setting of the 1st cam 15b, make its on arbitrarily angled because the power of spring 15d produces the power to engagement direction upset (opening → the locking direction) as auxiliary force.Like this, spring cam hinge 15 produces the power of close cap 3 directions, makes lid 3 be tending towards closing with the deadweight of lid 3.But, owing to friction hinge 16 produces and close cap 3 rightabout friction force, thereby can keep the posture of lid 3, perhaps make action level and smooth.
That is, spring cam hinge 15 plays the booster action of lid 3 switchings and the effect that keeps the cover closing state.In addition, the power of the direction of action of friction hinge 16 generations and lid 3 plays the state that keeps lid and allows the level and smooth effect of action.By changing these equilibrium of forces, also can realize opening automatically and closing automatically of lid 3.
More than, although understand the preferred embodiments of the present invention, but the present invention is not limited thereto, as long as just can carry out various deformation designs within the scope of the claims.For example, also the both ends 15k of the spindle unit 15a of described spring cam hinge 15 can be fixed on the casing 2, housing 15e is fixed on the lid 3.Equally, also the both ends 16d of the spindle unit 16a of described friction hinge 16 can be fixed on the casing 2, housing 16f is fixed on the lid 3.
In addition, in order to allow lid open-close maintaining body 14 keep balance, also can constitute lid open-close maintaining body 14 by a plurality of spring cam hinges 15 and a plurality of friction hinge 16.For example, also can a spring cam hinge 15 be set, constitute and 1 friction hinge 16 respectively is set in its both sides in central authorities.
By Figure 10 and Figure 11 other preferred embodiment of spring cam hinge and friction hinge is described.Spring cam hinge 115 as shown in figure 10, is made of the 1st flap 117 and the 2nd flap 118, is installed in the outside of casing 2 and lid 3.The 1st flap 117 is made of the 1st cam 115b, and the 2nd flap 118 constitutes the housing 115e of unillustrated spindle unit, the 2nd cam and spring among the figure that made folding and unfolding, is configured to allow spindle unit vertical with respect to 103 on lid.Described the 1st flap 117 is fixed on the either party's of casing 2 or lid 3 outside, and described the 2nd flap 118 then is fixed on the opposing party's outside.
In addition, friction hinge 116 as shown in figure 11, is made of the 1st flap 119 and the 2nd flap 120, and is arranged between casing 2 and the lid 3.The 1st flap 119 becomes the axle of the spindle unit of center of rotation 116a and this spindle unit of the two supports 116a by a spindle unit 116a rotating bearing component 116b and is constituted by having.The 2nd flap 120 becomes the axle of the spindle unit of center of rotation 116a and this spindle unit of the central support 116a by a spindle unit 116a rotating bearing component 116c and is constituted by having.Spindle unit 116a is fixed on the rotating bearing component 116c, when relatively rotating with axle rotating bearing component 116b, produces frictional resistance.Described the 1st flap 119 is fixed on the either party's of casing 2 or lid 3 outside, and described the 2nd flap 120 then is fixed on the opposing party's outside.
In addition, the lid open-close maintaining body of present embodiment, though with spring cam hinge as the 1st hinge, and with friction hinge as the 2nd hinge, be not limited thereto, also can adopt other hinges.
For example, as the 1st hinge, also can be the mechanism 204 of employing spring and coupling shaft shown in Figure 12.Adopt the mechanism 204 of spring and coupling shaft to constitute by spring 204a and coupling shaft 204b.The two ends of spring 204a are connected on casing 202 and the lid 203.Coupling shaft 204b is arranged to run through casing 202 and lid 203, and serves as that axle makes the lid 203 can freely openable with coupling shaft 204b.Under the state of Figure 12 (a), because because of spring 204a produces elastic force from direction to lid 203 that open, institute is so that lid 203 remains on open state.And when the state of Figure 12 (b), the power of spring 204a is turned to the closing direction of lid 203 at given angle, and lid 203 is closed.
