Description

The support device of slim screen

Technical field

The utility model is a kind of support body in order to the slim screen of fixed support.

Background technique

The utilization of slim screen is to the utmost to be general, except family, office space, more be common in public places such as station, cinema, saloon, and at present in order to fix the mode of slim screen, roughly be to establish a support device, a wherein end of support device is provided with conjunction base, is fixed in the screen back side for bolt passes conjunction base, and the other end with support device is fixed in wall or table limit again.Yet, in the time of need unscrewing bolt when desire replacing screen, often be subjected to the restriction in space, whole support device need be pulled down, can unscrew bolt, the disassemble or assemble screen is very inconvenient again.

For the suspension length, the angle that make slim screen can be adjusted, therefore, some support device is to establish with linkage type, promptly is provided with two sections support arms that are pivoted mutually at least, and packing and when carrying, two support arms can bend with reduced volume again in opposite directions, yet, there is no between present two support arms and place restrictions on setting, therefore, when bending pack, carry, when adjusting angle even, the surface of two support arms can be mutually against and make surface abrasion, influence quality.

In addition, when support device is when being fixed in the pattern on a limit, the end that its support arm differs from screen is that vertical fixing is on a strut, be to utilize the bolt end face packing that radially places between support arm and the strut, make support arm can not appoint easy deflection and change the angle of screen, yet, so be provided with, can make the bolt head that exposes destroy aesthetic property, then be the packing poor effect of bolt end face on the other hand, easily makes support arm deflection because of external force.

So the support device in order to fixing slim screen has the necessity that is improved in fact at present.

Summary of the invention

In order to improve above-mentioned disappearance, main purpose of the present utility model is to provide a kind of disassemble or assemble screen fast, the wearing and tearing of prevention two support arm surface collisions and keeps the complete support device of outward appearance.

Based on above-mentioned purpose, major technique means of the present utility model comprise one first support arm, and a wherein end of first support arm is provided with one first tubular connecting part; One second support arm, a wherein end of second support arm is provided with two second tubular connecting parts, two second tubular connecting parts are the tops that lay respectively at the first tubular connecting part, and in the second tubular connecting part and inside, the first tubular connecting part be equipped with the coaxial perforation of up/down perforation, first, second tubular connecting part promptly utilizes the perforation of coaxial setting to be the shape that is pivoted, differ from second this end of tubular connecting part in second support arm in addition and be provided with an outstanding clip piece, the free end end face of this clip piece is provided with an outstanding edge clipping, and the outer periphery of edge clipping are greater than the clip piece outer periphery; One conjunction base, be provided with a basal disc, the outer periphery that are positioned at basal disc are provided with the connecting part, be provided with perforation in the connecting part, being arranged with one in basal disc towards this end face of second support arm has three peripheries in addition, can supply the ㄇ shape draw-in groove of the edge clipping plug-in card of described clip piece, the periphery of this draw-in groove and basal disc is connected to form an opening portion, differ from an end of opening portion again in draw-in groove, be provided with the retaining edge that is positioned at the basal disc surface, the inner circumference edge of this retaining edge is less than draw-in groove.

Implement after the above-mentioned technological means, the effect that the utility model can play is that conjunction base is fixed in the screen back side, and owing to be the plug-in card shape between the clip piece of the conjunction base and second support arm, so when desiring to change screen, as long as screen is up extracted out together with conjunction base.And during desire assembling screen,, utilize the corresponding plug-in card of draw-in groove on the conjunction base on clip piece, to get final product again also as long as conjunction base is fixed in the screen back side, so the disassemble or assemble screen very easily and fast, even the space is minimum, do not need as existing product the whole support device of need dismantling yet.

In addition, the utility model is further established a limiter in first, second support arm pivot-connecting position, during the deflection folding, utilize the effect of this limiter, making first, second support arm forward a predetermined angle to promptly ends, and can not collide mutually, to prevent that first, second support arm from colliding mutually because nothing places restrictions on deflection, depainting.

Again, when first support arm of the present utility model is fixed on the strut, when being fixed on limit whereby, be provided with one between first support arm and the strut and draw the Fastening device of ensconcing in the strut, utilize this to draw the concealed Fastening device, keep the integrity of support device outward appearance, and reach certain packing, support arm can not rotated arbitrarily.
