Description

Multi-angle LCD display positioning bracket

Technical field

The invention relates to a multi-angle liquid crystal display positioning bracket.

Background technique

The positioning of the liquid crystal display in the display place usually depends on the wall panel and the support column. Since the wall panel is not flexible after fixing the liquid crystal display, and the display orientation of the display screen cannot be adjusted at multiple angles, the support column is often used. Position the LCD display. Because of the space convenience of the support cylinder, after the liquid crystal display is positioned thereon, it can be adjusted to the display orientation to be faced at will, and has greater adaptability.

Then the technical problem of using the support cylinder to position the liquid crystal display is that the back frame of the liquid crystal display is mostly locked to the support cylinder by the spring clamp (or clamp) and the bolt rigid plate, when the rotation angle of the liquid crystal display needs to be adjusted to Different display orientations often require re-disassembly and installation, which is cumbersome, time-consuming and labor-intensive, and still does not have flexibility.

Summary of the invention

The object of the present invention is to provide a multi-angle liquid crystal display positioning bracket with simple structure and convenient use, which can adjust the display angle and orientation of the liquid crystal display at multiple angles without complicated installation.

The technical solution of the present invention is: a multi-angle liquid crystal display positioning bracket, comprising a support rod, wherein the support rod is sleeved with a cylindrical base body, and further comprises an extension support rod, one end of the extension support rod is hinged for The hinge plate of the liquid crystal display is fixed, and the other end is fixed with a chuck. The outer wall of the cylindrical base body is circumferentially opened with more than one card slot for the extension of the extension rod to be clamped into the support positioning slot.

Based on the above main technical solutions, the additional technical features of the present invention are as follows:

In the present invention, the card slot extends longitudinally downward along the outer wall of the cylindrical base body, and the top end is open and the bottom end is closed.

Further, in the present invention, the inside of the card slot has a wedge shape with an upper width and a lower width.

In the present invention, the card slot is preferably designed as a slot having a "T" shape or an "L" shape or a "C" shape, and the card holder on the extension pole that cooperates with the card slot is a corresponding "T" card. Head or "L" shaped chuck or "C" shaped chuck. By designing the cross section of the card slot as described above and cooperating with the corresponding chuck, the stability of the positioning of the extension strut can be effectively improved.

In the present invention, at least one pressing screw for pressing the cylindrical base body to the support rod is radially penetrated on the side wall of the cylindrical base body, and an adjustment knob is fixed to the exposed end of the pressing screw. The compression screw is prior art, and its introduction is mainly to facilitate the more stable socket fixing of the present invention on the support rod, thereby ensuring the stability of the extension struts supported by the present invention. Moreover, an adjustment knob is fixed to the end of the pressing screw, so that the user can adjust the pressing screw without using a tool.

Further, further, the inner wall of the cylindrical base body is provided with a plurality of elastic pressing pieces corresponding to the pressing screw, and the pressing screw is pressed against the supporting rod by the elastic pressing piece. When the cylindrical base body is sleeved on the support rod, the elastic pressing piece is pushed by the pressing screw, and then pressed against the top supporting support rod by the elastic pressing piece, the contact area between the inner wall of the cylindrical base body and the supporting rod can be increased, and the contact area can be increased. Friction, thereby further enhancing the locking force of the cylindrical base on the support rod.

Alternatively, in the present invention, the cylindrical base body may be elastically sleeved and stretched on the support rod by means of a material such as plastic or rubber.

Alternatively, in the present invention, the cylindrical base body may be directly sleeved on the (movable) support rod, and the support rod is provided with an enlarged diameter portion for resting the cylindrical base body, and the expanded diameter portion may be a A ring boss, a few protrusions, or an axially extending taper. The cylindrical base body is fixed by the expansion of the enlarged diameter portion.

In the present invention, the outer cross section of the cylindrical base body may be circular, square or triangular, which is not limited in the present invention.

Preferably, in the present invention, the number of the card slots is more than one, and the circumferential circumferential equiangular angles are evenly spaced on the outer wall of the cylindrical base body. More card slots are provided to facilitate positioning of multiple liquid crystal displays, so that the liquid crystal display can be positioned at multiple angles without adjustment.

Preferably, the present invention further includes a base on which the bottom of the support rod is fixed (a practical case where the support rod can be fixed up and down in the building system without using a specific base).

The multi-angle liquid crystal display positioning bracket of the present invention is relatively simple to assemble in actual use, and the extension struts are usually only used in a single unit. After the fixing of the cylindrical base body on the support rod is completed, the chuck end of one end of the extending strut can be correspondingly engaged into the card slot on the cylindrical base body to complete the fixing of the extension strut. Then, according to actual needs, the hinge plate on the free end of the extension rod is fixed to the back frame of the liquid crystal display by a screw. Of course, the liquid crystal display can also be mounted first with the hinge plate and the extension struts, and then the extension struts are snapped onto the cylindrical base.

When a plurality of card slots are circumferentially arranged on the cylindrical base, if the display orientation of the liquid crystal display needs to be changed, the liquid crystal display is extracted with the extension struts and inserted into the card slot of another angle to complete the positioning, without As with technology, the positioning mechanism is tediously disassembled. Of course, according to actual needs, a plurality of extension struts can also be inserted by using the remaining card slots on the cylindrical base body, thereby simultaneously locating a plurality of liquid crystal displays, facilitating multi-directional display of the medium without disassembly, and enriching the display content. To improve the display.

The advantages of the invention are:

1. The multi-angle liquid crystal display positioning bracket of the invention has the advantages of simple structure and convenient use, in particular, facilitating the attachment and detachment of the extension struts thereon. When a plurality of card slots are circumferentially arranged on the cylindrical base, if the display orientation of the liquid crystal display needs to be changed, the liquid crystal display is extracted with the extension struts and inserted into the card slot of another angle to complete the positioning, without As with technology, the positioning mechanism is tediously disassembled.

2. The multi-angle liquid crystal display positioning bracket of the invention can also simultaneously position a plurality of liquid crystal displays, and can conveniently display the medium in multiple directions without disassembly, enrich the display content and improve the display effect.
