Description

The pivot of LCD and supporting structure

Technical field

The utility model is a kind of pivot and supporting structure that is used in LCD, is meant a kind of LCD pivot and supporting structure that is plugged in bearing easily and has the excellent support degree of stability especially, and can cuts down finished cost and material cost.

Background technology

Liquid crystal display television in the market or personal computer, for the demand that more meets ergonomics is provided, allow the user can adjust the angle of sighting distance and liquid crystal display equipment screen, one LCD pivot structure is provided usually, in order to connect a LCD and a bearing, make the operator be able to the angle suitable, so the LCD of adjustable angle has been the main flow of existing market, and has been inevitable popular trend with respect to this bearing adjustment.

A known LCD pivot structure as shown in Figure 9, it includes LCD web joint 40 ', pivot adjustment part 30 ', pad 74, support 70 and bearing (not shown), wherein, these support 70 bottoms are locked in bearing, its top protrudes out the support arm of two symmetries, and respectively combine with this LCD web joint 40 ' by a pivot adjustment part 30 ', again this LCD is locked in this LCD web joint 40 ', and then this LCD can be pivoted with respect to bearing, and the pivot adjustment part that it provides generally includes such as axostylus axostyle, space washer, saucer washer and screw togather required loaded down with trivial details members such as anti-skidding nut, cost height not only, easy break-down, and its axostylus axostyle, behind prolonged and repeated pivot, this that easily makes same axial line departs from axostylus axostyle is crooked gradually, make the pivot action of display be obstructed gradually and the difficulty that becomes, even display is tilted.When shipment is transported or carried in addition, LCD and bearing must be separated, with saving packaging space and material, yet it has shortcoming not easy to assemble or that take up space.

Therefore, the LCD pivot structure that provides a kind of easy dismounting to have the excellent support degree of stability in bearing is provided, and can cuts down finished cost and material cost.

Summary of the invention

Fundamental purpose of the present utility model is to be a kind of simple structure is provided and LCD with excellent support degree of stability pivots and supporting structure, and can cut down finished cost and material cost.

Another purpose of the present utility model is to be to provide a kind of LCD that is plugged in bearing to pivot and supporting structure, but makes LCD and bearing delamination packing, dwindling the wrappage volume, to save packing cost, and increase counter shipped quantity.

Another purpose of the present utility model is to be that the mounting means that provides the user to select LCD is wall-hanging or the pivot and the supporting structure of the last vertical type of table.

In order to reach above-mentioned purpose, major technique means provided by the utility model include a display web member, a pivot adjustment part, a hinge fixture and a connecting element; This display web member is L-shaped, on one side it is locked in the back side of this LCD, another side is provided with the angular setting hole that can wear and adjust angle for this pivot adjustment part; This pivot adjustment part comprises a hinge and an elastomeric pad, this hinge is common specifications product on the market, the intermediate portion is to adopt the hexagonal column to replace columned axostylus axostyle, from the structural mechanics viewpoint, the anchorage force of hexagonal cylinder itself comes by force than cylindrical anchorage force, if desire is strengthened cylindrical structural bearing capacity, then need increase its cylinder axostylus axostyle size etc. again, that is increase its overall weight and overall dimensions, in addition, in the time of as if the use right cylinder fixedly, the phenomenon of trackslipping is arranged easily, especially when using the large scale liquid crystal display, cause the effect of backlash easily because of gravity.

This hinge is in order to be inserted in the hexagonal hole of hinge fixture, increase the degree of stability of its anchorage force, these hinge two ends are respectively equipped with the threaded portion, wherein the threaded portion of an end is cylindric, in order to pass the hexagonal hole of hinge fixture, and it is locked on the circular hole of hinge fixture another side with nut, and the threaded portion of the other end cuts, following two planes, in order to penetrate the another side in described angular setting hole, and be inserted in elastomeric pad, with nut it is locked again, utilize the elasticity tension of this elastomeric pad, make and form tensioning and pivotable state between display web member and hinge; This hinge fixture is the groove shape of ㄇ font, the predetermined position on one side of this hinge fixture is provided with a hexagonal hole, one side with respect to the hexagonal hole, be provided with one with the circular hole of hexagonal hole identical central axis, on this hinge fixture, the limit face that is parallel to the hinge central axis is provided with several pilot holes, wherein, the design of the ㄇ font groove shape of this hinge fixture has following characteristic:

Difunctional grafting: the hinge fixture of this ㄇ font not only can be directly and display vertical type bearing link and use, also can be locked in wall-hanging bearing.

In light weight, rigidity is strong: with regard to mechanics of materials aspect, ㄇ font structure can be born, and to reverse the shearing rigidity very strong, approaching with square open column intensity, but weight only is about square open column half.

Manufacturing process is simple, and cost is low: the process of manufacturing of the hinge fixture of this ㄇ font is simple, cost is low, need use a large amount of fixed heads and structural member unlike other hinge (hinge) structure, not only increases cost, and overall weight and complexity are increased.

Material replaceability height, but the engineering properties difference of itself is little: when the approximate metal material of other rigidity of considering to migrate was made moulding, it bore, and to reverse intensity of shear little with original difference.

Can not rotate, and be easier to when the design of its ㄇ font groove shape makes it fixedly, conveniently install.

In sum, the utility model provides a kind of simple structure and has the excellent support degree of stability, can cut down finished cost and material cost and a kind of LCD that is plugged in the desktop bearing or is locked in wall-hanging bearing pivot and supporting structure.
