Abstract

The utility model relates to an improved pedestal structure of LCD screen, composed of an under frame, a spacer board and two shafts by which the under frame is pin connected with the spacer board; The pedestal of the LCD screen is provided with a spacing auxiliary device composed of a return spring, a retaining piece, and a plurality of screws; wherein, in the case that the pedestal is bent backwards, the leading end of the retaining piece that shifts laterally can sustain the stop portion of a shim in the shaft. When the pedestal rotates to a special angle, owing to the fact that the stop portion of the shim rotates along with the shaft, and a displacement occurs in the arcking guide groove. By now, the retaining piece pushes the pin into the space between the baffle at the side and the stop portion. The stop portion of the shaft, restricted due to the penetration of the retaining at the rear, cannot bend down and backward with an adjustment to the primary point, which allows the LCD screen to keep an optimal vision angle.

Embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail as follows:

As Fig. 1, Fig. 2 and shown in Figure 3, constitutional diagram and exploded view for the pedestal design of the utility model LCD screen, feature of the present utility model mainly is that the pedestal 1 of LCD screen is provided with spacing servicing unit 2, to allow this LCD screen can remain on best visual angle, wherein this pedestal 1 is mainly reached in order to articulate this underframe 11 respectively by underframe 11, location frame plate 12 and is formed with two rotating shafts 13 of location frame plate 12; Wherein the appropriate location on this location frame plate 12 is provided with screw 121, can be fixed at the back of LCD screen 3 for screw, and the both sides of this location frame plate 12 also are provided with axis hole (figure does not show); Corresponding and arranged on left and right sides bends the upright side shield 111 that is provided with respectively on this underframe 11, the upper end emargination of this side shield 111 is provided with an arc guide barrel 112, is provided with and the corresponding through hole of the axis hole of this location frame plate 12 (figure does not show) at the appropriate location below this arc guide barrel 112, on the side shield 111; These two rotating shafts 13 can wear the through hole of the both sides side shield 111 of the axis hole of frame plate 12 both sides, location and underframe 11 respectively and be fixed pivot joint.

Moreover, this position limit auxiliary device 2 is by a back-moving spring 21, one clamping sheet 22, several screws 23 are formed, wherein in the side of the side shield 111 wherein of pedestal 1, this underframe 11 is provided with a top and is the protruding bolt 114 that colludes shape, be provided with perforate 115 in the same side of this protruding bolt 114, between this protruding bolt 114 and perforate, be provided with several screws 116, at this moment, nationality is run through being of a clamping sheet 22 elliptoid adjustment hole 221 and locks in the screw 116 below it by screw 23 between this protruding bolt 114 and perforate, but also not exclusively lock, still maintain the usefulness that appropriate gap can be made transverse shift for this clamping sheet 22 between the underframe 11 to make this screw 23 and its lock; And this clamping sheet 22 is bent to form a hook part 222 with the appropriate location of protruding bolt 114 same sides of underframe 11; The lasso portion 211 at these back-moving spring 21 forward and backward two ends wears the hook part 222 of the clamping sheet 22 of the protruding bolt 114 of this underframe 11 and same side respectively, and nationality is by the elasticity of this back-moving spring 21 itself, so that the front end of this clamping sheet 22 moves in the orientation forward.

As Fig. 4, Fig. 5, shown in Figure 7, the rotational angle of the pedestal 1 of this LCD screen 3, but the rotation displacement of stop section 131 in the arc guide barrel 112 on side shield 111 tops of this underframe 11 in the rotating shaft 13 that nationality is articulated by frame plate 12 both sides, location, these location frame plate 12 rotations be can change and control and initial point and the most last point (about 0 °-90 ° of its rotational angle are adjusted to, promptly be equivalent to these location frame plate 12 backs of may command in conjunction with the rotatable angle that tilts of the LCD screen that sets firmly 3), have a large-scale rotational angle, and be beneficial to and make this LCD screen 3 can adjust a sight angle of suitably browsing; Yet the utility model is main is that a wherein side in this rotating shaft 13 is provided with spacing servicing unit 2, wherein when location frame plate 12 is in to layback, the front end of making the clamping sheet 22 of transversal displacement in this servicing unit 2 is resisted against the stop section 131 of the pad in this rotating shaft 13, when in case this pedestal 1 turns to special angle (being the visual angle of LCD screen to general user's the best in design) by the time, because the stop section 131 of this pad and then rotating shaft 13 is rotated and be subjected to displacement (promptly refer in the arc guide barrel 112 of this side shield 111 between the terminal and stop section 131 distance of generation certain angle) in this arc guide barrel 112, at this moment, to be nationality cover the elastic force of returning and preceding pushing away in the space that snaps between this side shield 111 and the stop section 131 by back-moving spring 21 to this clamping sheet 22, the restriction that the clamping sheet 22 that makes the stop section 131 of this rotating shaft 13 be subjected to its rear stretches into and can't swing back downwards again and be adjusted to initial point, to allow this LCD screen 3 can keep best visual angle, be available for users to enjoy the sense of watching of optimum field, thereby have the effect that control LCD screen 3 can keep best reclining angle; Again as shown in Figure 6, if when needing again this LCD screen 3 to be adjusted its rotation angle of inclination backward, only need this clamping sheet 22 that snaps between side shield 111 and the stop section 131 is pulled backward, can adjust the rotation angle of inclination of this LCD screen 3, allow this LCD screen 3 can tune to the required visual angle of beholder.

The pedestal design of improved LCD screen provided by the utility model when comparing mutually with aforementioned other known technologies, has the rotation reclining angle of may command LCD screen, to allow this LCD screen can keep the advantage of the visual angle of the best.

Though the utility model discloses with preferred embodiment; but it is not in order to limit the utility model; any those skilled in the art; the displacement of the equivalent assemblies of under the prerequisite that does not break away from design of the present utility model and scope, having done; or, all should still belong to the category that this patent is contained according to equivalent variations and modification that the utility model scope of patent protection is done.
