Next actuating module 60 is further illustrated, as shown in Figure 3, actuating module 60 to be optionally connected on this between element 42 and this release module 50, its one second Returnning spring 65 comprising an actuating fixture block 61 and be connected to this actuating fixture block 61, this second Returnning spring 65 is gone up this actuating fixture block 61 of pushing tow by precompressed in a second direction D2 (ginseng Fig. 6), after this actuating fixture block 61 of operation overcomes the elastic force of this second Returnning spring 65 further, this actuating fixture block 61 can move and optionally be butted on this release member 51 maybe element 42 on this on this second direction D2.As shown in Figures 4 and 5, activate fixture block 61 and have more an actuation button 615, extend to the bottom surface of substrate 70 and operate for user, user is by promoting actuation button 615, actuating fixture block 61 further can be compressed the second Returnning spring 65 from a non-actuated position and move to an actuated position, and maintained by inter-agency fixing and be positioned this actuated position, and once restriction cancellation, second Returnning spring 65 can discharge elastic force immediately and actuating fixture block 61 is reset to non-actuated position from actuated position, thus, this actuating fixture block 61 optionally switches between non-actuated position and actuated position.And in the accompanying drawing of the present embodiment, in order to the details of clear display second Returnning spring 65, therefore eliminate its other end against stationary plane, only understandably, second Returnning spring 65 is that one end is resisted against and activates the fixture block 61 and the other end is resisted against a stationary plane, the second Returnning spring 65 is made to be clamped and compress, to bestow the strength of pushing tow to actuating fixture block 61.
When actuating module 60 is positioned at this actuated position, the fixed end 4b of this auxiliary fixed force spring 4 is fixed in this main body 1, when described actuating module 60 is positioned at this non-actuated position, this main body portion 4a of this auxiliary fixed force spring 40 and this fixed end 4b is all with this load bearing seat 2 synchronizing moving.For the actuating fixture block 61 clearly demonstrating actuating module 60 switches produced component relation and effect between non-actuated position and actuated position, please then consult Fig. 6, Fig. 7 and Fig. 8, wherein Fig. 6 is the partial perspective view activating the utility model lifting structure 100 when fixture block 61 is positioned at non-actuated position, on this, element 42 extends a upper protruding block 421, this release member 51 extends a release projection 512, this actuating fixture block 61 extends one first projection 611 and one second projection 612, this first projection 611 can be relative to this upper protruding block 421 pulling or sliding, this second projection 612 can with this release projection 512 to pulling or relative sliding.Figure 7 shows that the generalized section of upper protruding block 421 along the A-A ' hatching of Fig. 6 and the first projection 611, and Figure 8 shows that the generalized section of release projection 512 along the B-B ' hatching of Fig. 6 and the second projection 612.Wherein this first projection 611 has one first to the face of pulling 6111 and one first inclined-plane 6113, this second projection 612 has one second respectively to the face of pulling 6121 and one second inclined-plane 6123, this upper protruding block 421 has one the 3rd to the face of pulling 4211 and one the 3rd inclined-plane 4213, and this release projection 512 has one the 4th to the face of pulling 5121 and one the 4th inclined-plane 5123.
Consult Fig. 6 to Fig. 8 in the lump and can know understanding, when activating fixture block 61 and being positioned at non-actuated position, upper protruding block 421 and the first projection 611 are offseting one from another along on first direction D1, and the second inclined-plane 6123 of the second projection 612 then abuts against each other with the 4th inclined-plane 5123 of release projection 512.Ground can be infered, because upper protruding block 421 and the first projection 611 offset one from another on the path of motion of upper element 42, if load bearing seat 2 moves down along first direction D1, upper protruding block 421 can not touch with the first projection 611, therefore cylinder 41, upper element 42, lower element 43 and auxiliary fixed force spring 4 can be driven synchronously to move down together.
Comparison diagram 3 and Fig. 9 known, when actuating module 60 is positioned at this non-actuated position, and this load bearing seat 2 orders about this cylinder 41 when moving from the top of this lifting structure 100, because element on this 42, this lower element 43 and this auxiliary fixed force spring 4 synchronously move with this cylinder 41 and this load bearing seat 2, now the fixed end 4b of auxiliary fixed force spring 4 is not fixed to this main body 1 with being directly or indirectly, therefore can not be stretched further but maintain reset condition in the process of auxiliary fixed force spring 4 movement.And main fixed force spring 3 is still carried on top by fixing and its free end moves along with load bearing seat 2 because of its body, therefore main fixed force spring 3 can provide main elastic force.Now, the main elastic force of main fixed force spring 3 is only had can be passed to load bearing seat 2.Because main elastic force is definite value, so the display device of a weight-matched (weight is M1) can be allowed at arbitrary height with stopping.
Following detailed description user forces in the actuation button 615 of the bottom surface protruding from substrate 70, actuating module 60 to be switched to the process of actuated position from non-actuated position.See also Figure 10 to Figure 12, shown in actuating module 60 by the schematic diagram of process operated, wherein Figure 11 shows that the generalized section of upper protruding block 421 along the C-C ' hatching of Figure 10 and the first projection 611, and Figure 12 shows that the generalized section of release projection 512 along the D-D ' hatching of Figure 10 and the second projection 612.
When actuating, fixture block 61 is stressed moves in a second direction d 2, need overcome the elastic force of the second Returnning spring 65 and second Returnning spring 65 that gradually reduces, now the first projection 611 and upper protruding block 421 local misalignment and overlapping in the first direction dl.On the other hand, second inclined-plane 6123 of the second projection 612 also with the 4th inclined-plane 5123 of release projection 512 can produce relative sliding and misplace, release projection 512 is pushed up by upper gradually, therefore imposes on the external force activating fixture block 61, also need to drive this release member 51 to overcome the elastic force of this first Returnning spring 55.
When external force continues to impose on actuation button 615 again, actuating fixture block 61 moves to actuated position the most at last, will as shown in FIG. 13 to 15, wherein Figure 13 is the partial perspective view activating the utility model lifting structure 100 when fixture block 61 has moved to actuated position, Figure 14 shows that the generalized section of upper protruding block 421 along the E-E ' hatching of Figure 13 and the first projection 611, and Figure 15 shows that the generalized section of release projection 512 along the F-F ' hatching of Figure 13 and the second projection 612.As shown in the figure, when the second inclined-plane 6123 and the 4th inclined-plane 5123 continue to slide, after offseting one from another in the first direction dl to this second projection 612 with this release projection 512, second inclined-plane 6123 of the second projection 612 has fully passed over the 4th inclined-plane 5123 of release projection 512 and no longer there is the relation of relative sliding, now impose on the external force removal of the first Returnning spring 55, therefore the first Returnning spring 55 will discharge elastic force immediately and be resetted by release member 51.As shown in Figure 14 and Figure 15, now change between this second projection 612 with this release projection 512 and contact to the face of pulling 5121 with the 4th to the face of pulling 6121 with second, and the first projection 611 is overlapping in the first direction dl with upper protruding block 421.
It should be noted that, the second Returnning spring 65 can be compressed because actuating fixture block 61 moves to actuated position, therefore after this first Returnning spring 55 resets this release member 51, this second projection 612 second to the face of pulling 6121 and this release projection 512 the 4th to the face of pulling 5121 because the second Returnning spring 65 continues lastingly in a second direction d 2 to exert a force to activating fixture block 61 and closely contact to pulling each other.Please consult Figure 16 further, now the first projection 611 is overlapping in the first direction dl with upper protruding block 421, therefore when cylinder 41 moves down, first of the first projection 611 can contact to pulling each other to the face of pulling 4211 with the 3rd of upper protruding block 421 to the face of pulling 6111 and limit element 42 on this.
Specifically, this load bearing seat 2 orders about this cylinder 41 when moving from the top of this lifting structure 100, because upper element 42 is subject to the restriction of this actuating fixture block 61, and the fixed end 4b of auxiliary fixed force spring 4 is connected to element 42 on this, therefore the fixed end 4b of auxiliary fixed force spring 4 is fixed to the actuating fixture block 61 of this main body 1 by element on this 42, only this main body portion 4a of this lower element 43 and this auxiliary fixed force spring 4 can synchronously move with this load bearing seat 2 and this cylinder 41, now this auxiliary fixed force spring 4 can be stretched, and this auxiliary elastic force is passed to this load bearing seat 2 via this cylinder 41.Adding main elastic force originally, now can mating the larger display device of a weight (weight is M2, and wherein M2 is greater than M1) at arbitrary height with stopping.
Next explanation is no longer needed auxiliary elastic force about thinking as user, pressing button release 515 is to remove the correlation technique content of auxiliary fixed force spring 4.In the present embodiment, because button release 515 is the bottom surfaces being revealed in substrate 70, be actually when therefore user presses button release 515 along first direction D1 upwards this button release 515 of pushing tow, make release member 51 in this first direction D1 upwards lifting.In detail, when the button release 515 of this release member 51 accepts an external force, when making this release member 51 compress this first Returnning spring 55 further, this release member 51 and release projection 512 thereof can move in the first direction dl, as shown in figure 17, until this release projection 512 offsets one from another in a second direction d 2 with this second projection 612.Because second of the second projection 612 is no longer mutual to pulling after staggering in the face of pulling 5121 with the 4th of this release projection 512 to the face of pulling 6121, this second Returnning spring 65 can discharge its elastic force immediately, and drive this actuating fixture block 61 to return back to this non-actuated position, now the relative position relation of upper protruding block 42, actuating fixture block 61 and release member 51, just can be returned to original state as shown in Figure 6 to 8.
Owing to only pressing actuation button 615 when load bearing seat 2 is positioned at the top of lifting structure 100, auxiliary fixed force spring 4 just can correctly be activated, therefore illustrate in another embodiment of the present utility model that actuation button 615 is pressed when load bearing seat 2 is not in the top of lifting structure 100, it gets back in the process of the top of lifting structure 100 how to dodge structural conflict automatic homing, make load bearing seat 2 again when the top of lifting structure 100 moves down, auxiliary fixed force spring 4 can correctly start, therefore lifting structure 100 of the present utility model has more fool proof feature.
In detail, as shown in figure 18, when user does not operate according to the mode of previous embodiment, such as this actuating fixture block 61 is still when non-actuated position, weight has been just that the display device carry of M2 is in load bearing seat 2 by user, this load bearing seat 2 can order about this cylinder 41 synchronously drive element 42, this lower element 43 and this auxiliary fixed force spring 4 on this to move down along first direction D1 away from the top of this lifting structure 100, and now auxiliary fixed force spring 4 is not by start.If user now just finds Lack of support and presses actuation button 615 and make this actuating fixture block 61 begin stressedly to move to this actuated position from this non-actuated position, because upper element 42 previously moved down, even if therefore pressed actuation button 615, auxiliary fixed force spring 4 does not still have effect.After pressing actuation button 615, the corresponding relation of release projection 512 and the second projection 612 repeats no more as shown in figure 15.Figure 19 is for along the upper protruding block 421 of G-G ' hatching in Figure 18 and the generalized section of the first projection 611, and the relativeness of the first projection 611 and upper protruding block 421, can obviously be found out by Figure 19, upper protruding block 421 and the first projection 611 are overlapping in the first direction dl.
The process that adjustment load bearing seat 2 gets back to the top of lifting structure 100 please consults Figure 20 to Figure 22 further, wherein Figure 20 is the partial perspective view of lifting structure 100, Figure 21 is depicted as the generalized section of upper protruding block 421 along the H-H ' hatching of Figure 20 and the first projection 611, and Figure 22 is depicted as the generalized section of release projection 512 along the I-I ' hatching of Figure 20 and the second projection 612.Understanding can be known from Figure 21, first inclined-plane 6113 and the 3rd inclined-plane 4213 of this upper protruding block 421 of this first projection 611 contact with each other and produce relative sliding and misplace, therefore upper protruding block 421 meeting pushing tow first projection 611 gradually, makes it move to drive this actuating fixture block 61 further to compress this second Returnning spring 65 towards second direction D2.As shown in figure 22, now the second projection 612 can away from release projection 512 on second direction D2.
Until after this first projection 611 and this upper protruding block 421 stagger in the first direction dl completely, 3rd inclined-plane 4213 of upper protruding block 421 has fully passed over the first inclined-plane 6113 of the first projection 611 and no longer there is the relation of relative sliding, therefore the second Returnning spring 65 drives this actuating fixture block 61 to return back to this actuated position immediately, now in lifting structure 100, the configuration of each element is as shown in figure 13, relative position relation wherein between upper protruding block 421 and the first projection 611 and between this release projection 512 and second projection 612, as shown in Figure 14 and Figure 15, separately do not repeat.
Therefore, if user's accidentally misoperation, when returning back to original state, interelement conflict can be located by automatically getting rid of, and user had previously pressed actuation button 615 makes this actuating fixture block 61 to actuated position still effective.
