Rotary shaft rack for liquid crystal display screen

Abstract

The present invention relates to a spindle support for supporting and fixing liquid crystal display screen, belonging to a transition device between the display screen and display screen base seat. Said spindle support includes the following several portions: a first fixing component, a pair of second fixing components a pair of interconnecting components, and elastic positioning device and an alignment regulation device. Said invention also provides the concrete structure of above-mentioned every portion.

Description

technical field [0001] The invention relates to a rotating shaft bracket for a liquid crystal display, which belongs to a transition device between a liquid crystal display and a display seat, and plays a role in adjusting the forward and backward angles of the liquid crystal display. Background technique [0002] A transition device is required between the liquid crystal display and the base of the liquid crystal display, that is, the transition is made through the rotating shaft bracket. take on, and must also effectively remain in the adjusted position. Therefore, the adjustment reliability of the rotating shaft bracket, the anti-fatigue problem, and the like are involved. If the rotating shaft is loose after a short period of use, the liquid crystal display cannot be positioned at the desired adjustment position, and even the expensive liquid crystal display will be damaged due to loss of positioning.

Problems solved by technology

The patent can objectively reflect the advantages described in the penultimate line 6 on page 5 to the first line on page 6 of the specification, but after observation and analysis by the applicant and actual verification, the patent still has the following four aspects The lack of: first, because the setting direction of a group of disc reeds (patent called elastic device) on the same adapter is in the same direction, they are combined together like a stack of discs, so the effect is tension The positioning effect essentially only plays the role of a disc-shaped reed, so the positioning effect is not ideal. In the actual use process, especially when it is used for a period of time, it is easy to cause positioning failure, which makes the adjustment of the LCD screen fail; two. The centering effect is poor, because it only sets all the components including the elastic device at one end of each adapter, but because the position of a pair of mounting holes on the LCD screen changes with different models, Therefore, it is impossible to make a pair of adapters meet the alignment requirements; the third is that dislocation is easy to occur during the rotation positioning process, because it relies on the tenons and reversing grooves of the positioning pieces set on the adapters and the reversing parts. Therefore, there is a risk that the adjustment and positioning will fail due to the tenon passing over the tenon, which will cause the LCD screen to fall suddenly without restraint or fall back suddenly without restraint and be damaged; Fourth, there are many parts and complex structure
