[embodiment]

Please join Fig. 3, shown in Figure 4, in support frame structure first embodiment of the present utility model, comprise a connection piece 30, have first pin-joint part 32 that a body 31 and is connected with body, and connect a junction 33 on the body, joint 33 has a fixed hole 330 and runs through joint 33; An and supporting member 40, have two struts 41, each strut 41 can be a ㄇ font body of rod and at one end has one second pin-joint part 411, after making strut 41 pass second pin-joint part 411 of strut 41 by first pin-joint part 32 of link 30, two struts 41 are articulated in link 30, have a torsion spring 431 and a sleeve 44 between two struts, 41 angles, torsion spring 431 is sheathed on first pin-joint part 32 that is installed up to link 30 behind the sleeve 44 again and connects two struts 41 respectively, on 32 ends of first pin-joint part, lock a retaining screw 45 is located at first pin-joint part 32 with fixed cover each element again, in present embodiment, first pin-joint part has screw thread on 32 surfaces, give sealedly for this screw, and the resistance that pad 46 causes to reduce friction is set between each element.

Hold above-mentioned, link 30 passes the casing back side that link 30 is pivoted to behind the fixed hole 310 of joint 33 liquid crystal display 10 via a screw 331 and nut 332, support by the side and the supporting member 40 of liquid crystal display 10 makes liquid crystal display 10 stand with a set angle of inclination; Each strut 41 of supporting member 40 all has a roller 421 as roll piece again, and each strut 41 is provided with a perforation 410 with respect to the other end of common pivot joint one end, pass the end that roller 421 is articulated in after the perforation 410 of roller 421 and strut 41 strut 41 by a Fixed latches 420, make supporting member 41 can in a plane of putting liquid crystal display 10 (for example: open desktop) or in the slippage of contracting.

As Fig. 5, shown in Figure 6, when liquid crystal display 10 when the angle with vertical line is tiltangle 1, the angle of two strut 41 correspondences is δ 1, when spurring toward liquid crystal display 10 the place aheads with adjustment tiltangle 1, tiltangle 1 diminishes and two relative struts 41 are inwardly pressed from both sides by the elastic force that is arranged at torsion spring 431 between the two, therefore the angle δ 1 between two struts 41 also diminishes, joint 33 at link 30 rotates with the pivot-connecting position of liquid crystal display 10 simultaneously, makes two struts 41 can withstand the plane of putting liquid crystal display 10 really.

As Fig. 7, shown in Figure 8, when liquid crystal display 10 when the angle with vertical line is tiltangle 2, the angle of two strut 41 correspondences is δ 2, when promoting toward liquid crystal display 10 rears with adjustment tiltangle 2, the thrust that two big and relative struts 41 of tiltangle 2 changes are transmitted by liquid crystal display 10 adds that the gravity of liquid crystal display 10 outwards opens two struts 41, therefore the angle δ 2 between two struts 41 also becomes big, body 31 at link 30 rotates with the pivot-connecting position of liquid crystal display 10 simultaneously, make two struts 41 can withstand the plane of putting liquid crystal display 10 really, when thrust disappears, then reach balance by torsion spring 431 elastic force between the gravity of liquid crystal display 10 itself and two struts 41.

Please join shown in Figure 9ly, among support frame structure second embodiment of the present utility model, comprise a connection piece 30, have a body 31 and one first pin-joint part 32, body 31 has a fixed hole 310 and runs through body 31, and an end of body 31 connects first pin-joint part 32; And a supporting member 40, have two struts 41, each strut 41 has one second pin-joint part 411, make strut 41 pass second pin-joint part 411 of strut 41 by first pin-joint part 32 of link 30 after, two struts 41 are articulated in link 30.

What present embodiment was different with earlier figures 4 embodiments is, has an extension spring 432 between two struts, 41 angles, extension spring 432 two ends are connected to two struts 41, lock a retaining screw 45 is located at first pin-joint part 32 with fixed cover each element again on 32 ends of first pin-joint part; Link 30 passes the casing back side that link 30 is pivoted to behind the fixed hole 330 of joint 33 liquid crystal display 10 via a latch 341 and pin bushing 342, support by the side and the supporting member 40 of liquid crystal display 10 makes liquid crystal display 10 stand with a set angle of inclination; Each strut 41 of supporting member 40 all has a ball 422 as roll piece again, the other end is provided with a perforation 410, with the perforation 410 of the end that ball 422 is articulated in strut 41 respectively, make supporting member 41 can in a plane of putting liquid crystal display 10 (for example: open desktop) or in the slippage of contracting.

Please join Fig. 5 to shown in Figure 8, it makes flowing mode with first embodiment support frame structure second embodiment of wood model utility, when liquid crystal display 10 when the angle with vertical line is tiltangle 1, the angle of two strut 41 correspondences is δ 1, when spurring toward liquid crystal display 10 the place aheads with adjustment tiltangle 1, tilt angle 01 diminishes and two relative struts 41 are inwardly drawn by the elastic force that is arranged at extension spring 432 between the two, therefore the angle δ 1 between two struts 41 also diminishes, joint 33 at link 30 rotates with the pivot-connecting position of liquid crystal display 10 simultaneously, makes two struts 41 can withstand the plane of putting liquid crystal display 10 really; When liquid crystal display 10 when the angle with vertical line is tiltangle 2, the angle of two strut 41 correspondences is δ 2, when promoting toward liquid crystal display 10 rears with adjustment tiltangle 2, the thrust that two big and relative struts 41 of tiltangle 2 changes are transmitted by liquid crystal display 10 adds that the gravity of liquid crystal display 10 outwards opens two struts 41, therefore the angle δ 2 between two struts 41 also becomes big, joint 33 at link 30 rotates with the pivot-connecting position of liquid crystal display 10 simultaneously, make two struts 41 can withstand the plane of putting liquid crystal display 10 really, when thrust disappears, then reach balance by extension spring 432 elastic force between the gravity of liquid crystal display 10 itself and two struts 41.

Compared to existing support frame structure, the utility model utilizes the display side next as fulcrum wherein Simplify support frame structure, not only can save the required man-hour of expending of visible angle and the strength of adjusting display, Also being available for users to by one hand is the visible angle of capable of regulating display, and improves user's operation facility The property, in addition, because the simple structure of the disclosed support frame structure of the utility model has again with low cost Advantage, improve the disappearance of prior art fully.
