Refer to Figure 1A and Figure 1B, when adjustment knob 31 is slided in perforation 30, positioning plate 46 must be driven to slide, and then locating column 32 must be slided between the first positioning hole 462a, the second positioning hole 462b and the 3rd positioning hole 462c.
More specifically, refer to Figure 1A and Figure 1B, locating column 32 is made up of two shell fragment 32a, each shell fragment 32a has a space to each other, first positioning hole 462a, second positioning hole 462b and the 3rd positioning hole 462c is communicated with respectively by a passage 462d to each other, and a width of passage 462d is less than a diameter of each positioning hole, therefore, when locating column 32 is by passage 462d, described shell fragment 32a is compressed because of space therebetween and close to each other, when locating column 32 moves to each positioning hole, described shell fragment 32a just rebounds original state, and make to continue holder to each other and have described space, and can be stuck in each positioning hole.
Finally, refer to Figure 1A and Figure 1B, support body 1 also connects with a connecting seat 5, and connecting base 5 can be used to connect with a display modular (scheming not illustrate).
In the present embodiment, the supporting frame 1000 of changeable tensile force can carry out triphasic adjustment, below detailed description supporting frame 1000 is adjusted to respectively the first stage, second stage and the phase III time, each assembly start relation to each other.
First, when supporting frame 1000 is adjusted to the first stage, please refer to the drawing 1D, as the primary importance L1 that adjustment knob 31 is slided as shown in figure ip, as shown in Figure 1A, locating column 32 is sticked in the first positioning hole 462a, and makes positioning plate 46 be positioned at one first location P1.Now, first cylinder 470 is arranged in the first sliding area 460a, and the first cylinder 470 is positioned at a first end 4601 of the first sliding area 460a, as shown in Figure 1 C, connecting base 5 now has a distance (namely display modular is positioned at extreme higher position) farthest with base 3.User may because the height of self-demand adjustment display modular, and then need connecting base 5 to move down and close towards base 3, support body 1 and pivotal axis 2 thus can be driven to rotate and near base 3 simultaneously.
From the above, when support body 1 folds towards base 3, as shown in Figure 2 C, pivotal axis 2 pulls connecting line 42, connecting line 42 is made to pull holding base 41, and then first elastic component 43 that stretches, simultaneously, holding base 41 drives the first link 47 by the second elastic component 44, and the first cylinder 470 is slided towards a second end 4602 by the first end 4601 of described first sliding area 460a.That is, because the first sliding area 460a is parallel with the draw direction D of the second extension spring 440, therefore, first cylinder 470 can slide in the first sliding area 460a, under the loose situation in wherein one end of the second extension spring 440, can't be stretched each second extension spring 440, only has the first extension spring 430 of the first elastic component 43 to be stretched.In other words, the first extension spring 430 is only had to provide pulling force to reach support effect folding in process.
When supporting frame 1000 is adjusted to second stage, refer to Fig. 3 A and Fig. 3 B, when adjustment knob 31 slides into a second place L2, positioning plate 46 is driven to slide relative to base 3, locating column 32 is sticked in the second positioning hole 462b, and make positioning plate 46 be positioned at one second location P2, and the first cylinder 470 is positioned at the first limiting area 460b.
Refer to Fig. 3 C, when support body 1 folds towards base 3, pivotal axis 2 pulls connecting line 42, connecting line 42 is made to pull holding base 41, because the first limiting area 460b is perpendicular to draw direction D, therefore, when first cylinder 470 is positioned at the first limiting area 460b, limit by the first limiting area 460b and cannot slide, wherein one end of each second extension spring 440 is limited too and cannot moves, and makes each second extension spring 440 be in the state that can be stretched.Therefore folding in process, stretch the first extension spring 430 and the second extension spring 440 simultaneously, so when being positioned at the first location P1 compared to positioning plate 46, can support heavier display modular.
It should be noted that especially, in above-mentioned first stage or second stage, namely when adjustment knob 31 is positioned at one of them of primary importance L1 or second place L2, the 3rd extension spring 450 folding the 3rd elastic component 45 in process all can not be stretched, this is because one second width W 2 of the second sliding area 461a is one first width W 1 (consulting Figure 1B) being greater than the first sliding area 460a, even if positioning plate 46 is adjusted to the second location P2 (upper left corner namely toward Figure 1B is moved) from the first location P1, second cylinder 480 still remains in the second sliding area 461a, therefore can not be stretched.
And when supporting frame 1000 is adjusted to the phase III, refer to Fig. 4 B, namely when adjustment knob 31 slides into a 3rd position L3, positioning plate 46 is driven to slide relative to base 3, as shown in Figure 4 A, locating column 32 is sticked in the 3rd positioning hole 462c, and makes positioning plate 46 be positioned at the 3rd location P3, now the second cylinder 480 relative movement and enter the second limiting area 461b.
Refer to Fig. 4 C, when support body 1 folds towards base 3, pivotal axis 2 pulls connecting line 42, connecting line 42 is made to pull holding base 41, because the first limiting area 460b and the second limiting area 461b is all perpendicular to draw direction D, therefore, the restriction that the first cylinder 470 and the second cylinder 480 are subject to the first limiting area 460b and the second limiting area 461b respectively cannot be slided, and then therefore stretch the first extension spring 430, second extension spring 440 and the 3rd extension spring 450 simultaneously.
Therefore, by positioning plate 26 at the first location P1, the second location P2 or the 3rd location P3, and make the present embodiment supporting frame 1000 be adjusted to the first stage, second stage and the phase III time, the display modular of Different Weight can be supported respectively, 23 inch display modulars of the 20 inch display modulars of such as 7 kilograms, the 21 inch display modulars of 9.5 kilograms and 12 kilograms.So, do not limit the tensile force of the first elastic component 43, second elastic component 44 and the 3rd elastic component 45 in this, quantity and the tensile strength of the first extension spring 430, second extension spring 440 and the 3rd extension spring 450 can be adjusted according to demand.
In the present embodiment, refer to Figure 1A and Figure 1B, in order to increase the bearing capacity of supporting frame 1000, the supporting frame 1000 of the changeable tensile force of the present embodiment also comprises a torsion spring group 6 and is arranged on base 3, and connect with pivotal axis 2, torsion spring group 6 comprises two sides that two torsion spring unit 61 are hubbed at pivotal axis 2 respectively, jointly to bear the weight of display modular.But, in other embodiments of the utility model, torsion spring group 6 can be omitted according to demand, the effect of bearing display modular weight can be reached equally by adjustable stretching structure 4 merely.
In sum, by the slip of adjustment knob, positioning plate is made to obtain relative sliding to different location, can the stretching quantity of adjustment elastic component of multi-section type, and then user must carry out the supporting power of corresponding adjustment supporting frame according to the weight of bought display modular, even and if user replaces the display modular of Different Weight, only must carry out correspondence adjustment by adjustment knob, and again need not buy applicable supporting frame again, also allow simultaneously user operate time the utility model supporting frame time, preferably operating handle can be experienced.
Above-described embodiment is only used for exemplifying enforcement aspect of the present utility model, and explains technical characteristics of the present utility model, is not used for limiting protection category of the present utility model.Those skilled in the art the arrangement of unlabored change or isotropism can all belong to the scope that the utility model advocates, rights protection scope of the present utility model should be as the criterion with the right of application.
