The bracing frame armature apparatus of LCD
Technical field
The utility model relates to a kind of connecting elements, relates in particular to a kind of LCD panel display back side that is installed in and connects bracing frame, allows the bracing frame armature apparatus of the deployable or LCD that folds of bracing frame.
Background technology
The LCD of complanation (Liquid Crystal Display; LCD) because of having plurality of advantages such as little, in light weight, the low radiation of volume, replace traditional cathode-ray tube (CRT) (CathodeRay Tube gradually; CRT) formula display, and widely people choose use.
Though this LCD has the advantage that the body flattening does not take up space,, need be supported the location by a bracing frame because of the body of its flat can't directly be placed on the desktop.Known applications generally can be divided into two big classes in the bracing frame design of LCD at present, the one person is that a base group is established the bracing frame that a support member is constituted, in order to installing LCD bottom, allow LCD not contact the form of desktop, the support of asking for an advance on one's pay is placed on table and goes up use, though this support frame structure can provide the preferable support of LCD one firm, its structural design is comparatively complicated, member is many, and cost is high and still have the shortcoming that takes up space; Its two be plain type support bar form, the body of rod of this bracing frame is to cooperate an armature apparatus to be connected in the LCD back side, allow the LCD bottom contact desktop, bracing frame is in its back support, and design by armature apparatus, allow this bracing frame can adjust the angle of relative LCD, change the angle of inclination of LCD, the design of the bracing frame of this simple and easy support bar form has advantages such as simple in structure, that member is few, cost is low and can fold, for the support frame structure of the another kind of simple type of user's use.
In aforementioned, be applied to armature apparatus between plain type bracing frame and LCD because of relate to bracing frame with respect to LCD be connected and adjust angle so, for whole LCD, armature apparatus is an indispensable significant components.Be applied to the latest type armature apparatus design of LCD bracing frame at present, disclosing US2002/0002759 A1 number " LCD hinge assembly (HINGE ASSEMBLY FOR LCD MONITOR) " as the U.S. introduces, this hinge assembly have one can affixed bracing frame upper end connecting elements 201, this connecting elements 201 is installed a hinged arm 208 with respect to other side of bracing frame, these hinged arm 208 two ends are installed torque spring 209 and supporting member 204 respectively, install nut more endways.Aforementioned torsion spring 209 1 ends are resisted against on the connecting elements 201, end is arranged in the horizontal segment 206 of supporting member 204 in addition, supported on both sides member 204 can cooperate affixed assembly to be fixedly arranged on the back side of LCD by its vertical section 205 in addition, its horizontal segment 206 is provided with spacing short slot 207, connecting elements 201 sides are arranged in this spacing short slot 207, and constitute a hinge assembly that is connected between LCD and the bracing frame, and allow the relative LCD of the bracing frame back side adjustment angle of outwarding winding, and then change the angle of inclination of LCD.
Yet, the structural design of aforementioned hinge assembly is for can this LCD of safety supports, connecting portion 206 sides that the support member 204 of this hinge assembly extends laterally are provided with the stopper slot 207 of certain openings angle, horizontal connecting portion 201 for bracing frame is placed in one, limit this bracing frame and allow the scope of activities of adjusting angle, that is after this bracing frame folds, be subject to the stopper slot scope, its bracing frame can't rotate near the LCD back side, so this LCD is when vanning is transported, its required packaging space is bigger than normal, need to use bigger packing case, cause shipment and delivery cost higher, and be unfavorable for this competitiveness of product.
The utility model content
In order to overcome the above-mentioned shortcoming that prior art exists, the utility model provides a kind of bracing frame armature apparatus of LCD, it both can allow bracing frame safety supports LCD, and when packing, can allow this bracing frame rotation and be affixed on the LCD back side, have the effect of dwindling packaging space and reducing shipment and delivery cost.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of bracing frame armature apparatus of LCD, this armature apparatus are to be mounted on the LCD back side to connect bracing frame, to support LCD, it is characterized in that, comprise: a connecting elements, the one end is for connecting the connecting portion of bracing frame, and end is for having the Fixed Division of coupling hole in addition; One pivot is to be fixedly arranged in the coupling hole of connecting elements Fixed Division with the stage casing, and its left and right end tip respectively has the threaded portion; Two limiting plates are to be installed in respectively on the left and right end of pivot, and central authorities form for pivot runs through wherein through hole, and lateral margin is provided with the first spacing short slot, the second spacing short slot, and the recessed edge in first location, the recessed edge in second location; Two supporting members, be to be installed in respectively on the left and right end of pivot with respect to the limiting plate outside, this supporting member is the body that erection part side extending level portion constitutes, be to cooperate affixed assembly to be fixedly arranged on the LCD back side on this erection part, be provided with in this horizontal part for the pivot end and run through wherein through hole and fixed orifice, upper limb is formed with recessed edge, has extended laterally lug towards the side root edge of pivot centre, and lug extends in the second spacing short slot of the adjacent limiting plate of side; Torque spring in two is to be installed in the connecting elements two ends respectively in abutting connection with proximal limiting plate place, runs through wherein for pivot, and its first end is resisted against on the connecting portion of connecting elements, and second end is arranged in the recessed edge in second location of limiting plate; Two outer torsion springs are to be sheathed on respectively on the left and right end of pivot with respect to the two supporting members outside, and its first end places the fixed orifice of supporting member horizontal part, and second end extends in the recessed edge in first location of the recessed edge of supporting member horizontal part and limiting plate; Two nuts are that spiral shell is located on the threaded portion of left and right end of pivot the fixedly outer torsion spring outside of butt respectively, whereby, constitute the armature apparatus of a LCD bracing frame.
