Embodiment
Below in conjunction with accompanying drawing, but the locating support that describes the utility model positioning rotating shaft in detail and use this positioning rotating shaft.
With reference to Fig. 1, positioning rotating shaft shown in Figure 2, comprise coupling shaft 2, movable frame 3, positioning means (being formed by movable part 51 and fixed block 52) and compressing member 4.Coupling shaft 2 one ends are provided with the first flat position 21 and 21 the inners, anti-slip tank 25, the first flat positions are provided with the shaft shoulder 22.This part of coupling shaft 2 and supporting frame or dunnage interference fit are with tight grafting.Also be provided with screens groove 23 on the coupling shaft 2, screens groove 23 is for fixing jump ring 6, and jump ring 6 is used for keeping in the axial direction the location of coupling shaft 2.In addition, the other end of coupling shaft 2 is provided with flat position, the second flat position 24, the second 24 and matches with movable part 51.
Be provided with mounting hole 31 at described movable frame 3, mounting hole 31 is for installing and fixing with flat panel display equipment.Certainly, except mounting hole 31, movable frame 3 can adopt other forms with the mount fixing structure of flat panel display equipment, as clamping, socket joint connection etc.Also be provided with axis hole 32 at the movable frame middle part, in a side of axis hole 32, be provided with centrosymmetric two locating columns 33, these two locating columns are for fixing with the mounting groove 521 of fixed block 52.A parts compressing member 4 in addition is to be laminated by 3 shell fragments, and is installed in by screw on the tapped hole 37 of movable frame 3.On movable frame 3, can also see a movable part 51, said as preamble, movable part 51 is inserted on the coupling shaft 2.And, the inside of movable part 51 is provided with the mounting hole 511 corresponding with the second flat position 24, be provided with screens plane 512 in the mounting hole 511, the meaning of this mounting hole 511 is, make coupling shaft 2 when rotating, can drive movable part 51 and rotate, and movable part 51 can move on the axial position of coupling shaft 2.
Below, will explain the work relationship of fixed block 52 and movable part 51 in conjunction with Figure of description 2.
As shown in Figure 2, be respectively equipped with recess 522 and projection 513 on fixed block 52 and movable part 51 facing surfaces.Be specially, fixed block 52 upper edge axis hole central distribution have 6 to fall trapezoidal recess 522, fall trapezoidal projection 513 and be provided with 2 at movable part 51, and wherein the shape of projection 513 is meshed with recess 522, to realize positioning action.What need further specify is that recess 522 herein is formed by a plurality of protruding structures, and is differential owing to having between the top and bottom of a plurality of protruding structures, therefore formed so-called recess 522 between adjacent protruding structure.The effect of recess 522 has provided the engagement position, therefore those skilled in the art also can apparently be interpreted as recess 522 groove of being located on the fixed block 52, and no matter be part between the adjacent protrusion shown in the present embodiment, or groove, as long as it has different up and down differential positions, all should think to belong to the described recess 522 of the application's application.
And projection 513 has two and be symmetrically distributed in annular, this arrangement makes projection 513 stressed evenly, avoid loss.And recess 522 is trapezoidal, and recess 522 has 6 and be evenly or non-uniform Distribution in annular.The trapezoidal inclined-plane that falls of recess 522 makes projection 513 can skid off or slip into recess 522 along the inclined-plane, to switch engagement and separated state.The distributed quantity of recess 522 is relevant with location sum of series orientation angle during with distributing position, recess 522 corresponding one rotate orientation angles, 522 multistage location of correspondence of a plurality of recesses.Can adjust orientation angle by the distribution mode of adjusting recess 522, such as being equally distributed when recess 522, then Ding Wei angle of swing difference is identical.
Certainly, effect is another kind of replaces, and projection 513 can be arranged on the fixed block 52, and recess 522 is arranged on the movable part 51, and working principle is with last identical.
As Fig. 3, Fig. 4 and shown in Figure 5, shown the applied locating support of rotating shaft.This locating support has adopted dunnage 1 structure, wherein, an end of coupling shaft 2 inserts and to be installed in the pin-and-hole 11 of dunnage 1, and the 11 interior screens of the first flat position 21 and pin-and-hole match, and making the shaft shoulder 22 sides fit to dunnage 1, anti-slip tank 22 makes coupling shaft 2 cooperate tightlyer with pin-and-hole 11; The axis hole 32 that the other end of coupling shaft 2 passes movable frame 3 fits to movable frame 3 sides until the shaft shoulder 22 sides; Jump ring 6 is stuck on the screens groove 23 of coupling shaft 2 to limit moving axially of movable frame 3; Fixed block 52 is inserted in coupling shaft 2, positions by mounting groove 521 and movable frame 3 locating columns 35; Movable part 51 is inserted in coupling shaft 2, and its screens 512 is cooperated with the second flat position 24 of coupling shaft 2, and movable part 51 and coupling shaft 2 are rotatablely moved synchronously, but movable in the axial direction motion.Compressing member 4 screws and adjusts screw 41 until pressing movable part 51 by being installed on the mounting hole 37 of movable frame 3 by pressure-adjusting screw 41.Degree of tightness in the time of can adjusting supporting frame 1 and start and depress by adjusting screw 41 makes dull and stereotyped electronic equipment can keep suitable angle and is not easy and dislocates.
When needs at a certain angle during the support plate display device, rotational support plate 1, when starting, dunnage 1 drives coupling shaft 2 rotations, be connected the also and then rotation of movable part 51 on the coupling shaft 2 this moment, give 52 1 active forces of fixed block by falling the contact inclined-plane of dovetail groove during movable part 51 rotation, fixed block 52 is given 51 1 reaction forces of movable part by the contact inclined-plane simultaneously, because fixed block 52 is to be fixedly mounted on the movable frame 3, movable part 51 is forced to produce axially outwards mobile under the effect of reaction force axial thrust load, makes the projection 513 of movable part 51 recess that slides out.When rotatablely moving of coupling shaft 2 forwards next recess 522 edges to, continue rotation, then compressing member 4 slips into next recess again with movable part 51, and projection and recess mesh again and locate at this moment.When needs reduce angle and use, depress dunnage 1, drive coupling shaft 2 counter-rotatings, be installed in the also and then counter-rotating of movable part 51 on the coupling shaft 2 this moment, and movable part 51 and fixed block 52 cooperatively interact working principle with on be identical.
Extremely shown in Figure 9 as Fig. 6, the change situation that has shown the position shelf support angle respectively, owing to adopted the application's positioning rotating shaft structure, make and multistagely to locate in the rotation process, different recess quantity can cooperate with distributing position and draws different location quantity and orientation angle, again from figure as can be known, this locating support can position in 0 degree, 30 degree, 90 degree and 145 these several angles of degree.
But positioning rotating shaft of the present utility model also can be installed on the distinct device, such as other shaft positioning device such as door, window.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change and revise above-mentioned mode of execution.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
