The support frame of the improved wedge-shaped plug-in and quick-release mechanism at the top of the column

Abstract

The invention relates to an improved supporting frame for a stand column top wedge insertion and extraction quick release mechanism. The supporting frame comprises a base, a stand column and a screen connecting assembly. The screen connecting assembly comprises a horizontal shaft, a fixing portion and a wedge-shaped stretching portion formed by integrally-formed metal, wherein the stand column comprises a wedge-shaped slotted hole integrally formed by metal; the supporting frame is characterized in that a plastic shock insulator made of plastics is fixedly arranged on the outer surface of the wedge-shaped stretching portion or the inner surface of the wedge-shaped slotted hole, the surfaces, achieving cooperation during insertion and extraction, of the two wedge-shaped structures are matched partially or wholly through the plastic shock insulator, so that the characteristic that the plastic shock insulator can more easily generate micro-deformation when being stressed is utilized, insertion and extraction connection is more smooth, more free, more convenient and more rapid, meanwhile, matching is tight, no looseness is caused, more reliability is achieved, and particularly combination can still be stable after repeated usage; meanwhile, the insertion and extraction structure can be used as a spraying outer part, particularly, the machining precision is greatly lowered, machining and manufacturing are easy, and the production cost is lower.

Description

technical field [0001] The invention relates to the field of support frames for displays, in particular to a quick disassembly mechanism for the support frames. Background technique [0002] Along with the flourishing development of digital audio-visual, the application of liquid crystal display is extremely extensive, and correspondingly, supporting frame supporting it, supporting display and adjustable viewing angle is also used in large quantities. However, after the display is installed on the support frame, the entire product is very bulky. If the display and the entire support frame are packaged and transported as one, the packaging volume will be large, the packaging material consumption will be high, the cost will be high, and the transportation cost will be higher, and it is obviously not environmentally friendly. Therefore, if most of the support frame can be easily disassembled from the display and then packaged for delivery and transportation, the packaging volum...

Problems solved by technology

[0014] However, the most important structural part of the quick release structure of the prior art support frame, that is, a pair of wedge-shaped structures in the front and rear directions that are adapted are all metal parts, that is, the wedge-shaped structures that are inserted and pulled out are metal-to-metal mutual cooperation. , and the hardness of the metal parts is too high, the matching and adaptation are head-to-head, but the actual manufacturing size and shape will always have some errors and defects. The support frame is not allowed; even if the wedge angle is suitable, if the volume of the wedge-shaped protrusion is too large or too small, it cannot be inserted into the bottom of the wedge-shaped slot hole, especially if the volume of the wedge-shaped protrusion is too small to cause gaps, looseness or shaking , unstable; when it is too large, there will be a large appearance seam at the external joint of the two, which will affect the appearance; if it is to be well matched, the processing cost will rise sharply, but even if this is done, the metal-to-metal fit will always give the fit It brings about the problem of bad hand feeling. For example, it is a good thing to fit accurately, but it will be very difficult to disassemble and pull out, which is very unfavorable to the disassembly of the support frame; there is also poor repeatability of the combination after multiple disassembly and assembly; and , the plug-in structure often needs to be made into appearance parts, and the problem is particularly prominent when painting is required, and the paint surface is easily damaged by plug-in and pull-out

It can be seen that there are still many defects in the adapted wedge mechanism, which needs further improvement.
