Description

Pitch angle regulating apparatus for video-frequency displaying device

The utility model relates to a kind of luffing angle adjusting device of video display.

Video display because of user's difference, need be adjusted its luffing angle and horizontal direction in use sometimes, to reach state comfortable when using, so, the also indefatigability of before it, working for a long time, and avoid affecting one's power of vision.

All be to contact between each movable element of video display angular adjustment apparatus at present in the sliding friction mode.That is, in the time will adjusting luffing angle, the user must overcome interelement force of sliding friction could the rotating angle adjuster.

Above-mentioned known mode still can be fit to the small size video display, because of its weight lighter.

It is the trend that reaches future at present that the large scale video display replaces small size person, and heavier because of its weight, as if the user has found to adjust luffing angle and horizontal direction is not too easy, and this is the result because of aforementioned force of sliding friction fully.

The purpose of this utility model is to provide one to adjust easy video display luffing angle adjusting device.

The purpose of this utility model is to realize like this, a kind of luffing angle adjusting device of video display promptly is provided, it comprises: a upper pedestal, it has the upper surface of one one-tenth concave curve surface shape, concave curved surface forms a dented space, upper pedestal has several groove caves, and a running roller in the groove cave, running roller are exposed to outside the groove cave slightly; One angle adjustment body has a Lower Half, and Lower Half becomes a convex surface shape, and the Lower Half seat of this convex surface shape contacts in the rolling friction mode with running roller on described running roller; One coupling apparatus that angle adjustment body and upper pedestal slidably are connected.

This luffing angle adjusting device of the present utility model has made each element in the adjusting device of prior art to contact in the rolling friction mode into, is very easy to so adjust.

Below with reference to accompanying drawing the utility model is described in detail, in the accompanying drawing:

Fig. 1 is the three-dimensional exploded view of each element of the present utility model;

Fig. 2 is the bottom view of upper pedestal of the present utility model;

Fig. 3 is the profile of angle adjustment body of the present utility model when combining with upper pedestal;

Fig. 4 is the profile of upper pedestal of the present utility model when combining with lower base;

Fig. 5 is the profile of upper and lower pedestal rotation of the present utility model junction;

Fig. 6 is the state diagram coupling apparatus of the present utility model combines the location with upper pedestal before;

Fig. 7 is the state diagram coupling apparatus of the present utility model combines the location with upper pedestal after.

As shown in Figure 1, luffing angle adjusting device of the present utility model comprises a upper pedestal 10, an angle adjustment body 11, a coupling apparatus 12.

101 one-tenth concave curve surface shapes of a upper surface of upper pedestal, concave curved surface 101 forms a dented space, upper pedestal 10 has several groove caves 102, be provided with a running roller 103 in the groove cave 102, when running roller 103 is put in it, be exposed to slightly outside the groove cave, this is found in Fig. 3, and upper pedestal 10 about middle positions have first conduit 104 that runs through pedestal.

Angle adjustment body 11 has a Lower Half 111, becomes a convex surface shape, its about middle position has one second conduit 112 that runs through body, 111 of the Lower Halves of convex surface shape contact in the rolling friction mode with running roller on aforementioned running roller 103, and this can be with reference to figure 3.

Coupling apparatus 12 runs through second conduit 112, first conduit 104, and angle adjustment body 11 and upper pedestal 10 are slidably linked.

Coupling apparatus 12 has a plurality of elastic fastening hooks 121, this elastic fastening hook 121 is passed second conduit 112 after, pass the respective grooves in first conduit 104 again, be coupling apparatus 12 situation of no-fix still this moment, as shown in Figure 6.

Upper pedestal 10 has block 106 and projection 105 for the counterpart of combination.After coupling apparatus 12 carries out according to the assembly direction of Fig. 6, because of elastic fastening hook 121 stressed can along shown in direction by projection 105, become state behind the location of Fig. 7.The acting as of projection 105 prevents that coupling apparatus 12 from drawing back.Block 106 prevents that then coupling apparatus 12 from marching forward again.But if 12 palpuses of desire dismounting coupling apparatus according to the compressing of direction shown in Fig. 7 elastic fastening hook 121, make it break away from projection 105 and simultaneously coupling apparatus 12 are promoted (rightabout of Fig. 6 direction) to the dismounting square.

Referring to Fig. 3, it is an angle adjustment body 11 with after upper pedestal 10 combines, the profile of its contact site branch.Thus figure as can be known, body 11 be seat on running roller 103, the contact of constitute rolling, and application of force turn body 11 and adjust its luffing angle.

As shown in Figure 1, horizontal direction adjusting device of the present utility model comprises a upper pedestal 10, a lower base 13.

By the bottom view of upper pedestal 10, as shown in Figure 2 in, the bottom of upper pedestal 10 has a plurality of grooves cave 107 as can be known, is provided with a running roller 108 in this groove cave 107, after lower base 13 combination, running roller is exposed to outside the groove cave 107, as shown in Figure 4 slightly.

Lower base 13 combines with upper pedestal 10, and it has a circumferential conduit 131 at least, when upper pedestal 13 is done the direction adjustment and driven running roller 108 when rotating and roll in conduit 131.

The bottom of upper pedestal 10 has a chimeric block 109, has the elastic fastening hook 132 of a correspondence on the lower base 13, make chimeric block 109 and elastic fastening hook 132 be aligned with each other chimeric it, as shown in Figure 5, rotate the action that both promptly finish the body combination of the upper and lower end simultaneously.If desire is dismantled both, at first rotate both chimeric block 109 is alignd with elastic fastening hook 132, according to direction pushing elastic fastening hook 132 shown in Figure 5 it is separated with chimeric block 109, promptly reach both purposes of dismounting.

By among Fig. 4 as can be known, make level angle and adjust when rotating upper pedestal 10, because of 131 one-tenth rolling friction of its running roller 108 and lower base conduit contact, so frictional force is very little, required strength is less, the usefulness of suitable large scale video display horizontal direction adjustment.

Mandatory declaration be that though the utility model is at large-sized video display devices, this conception stands good in the lighter video display devices of small size.
