Description

Double spring lifting mechanism for LCD monitor stand

technical field

The utility model relates to a double spring lifting mechanism of a liquid crystal display support.

Background technique

Due to the advantages of light weight, thin body and low radiation, liquid crystal displays have gradually replaced traditional fluorescent displays. The liquid crystal displays currently on the market generally include a liquid crystal panel and a fixed seat, and the fixed seat includes a base, a support frame whose lower end is fixed to the base, a mounting plate for installing the liquid crystal panel, and a slewing frame connecting the support frame and the mounting plate, wherein the slewing frame It is fixed to one of the support frame or the mounting plate and pivotally connected to the other through a hinge device, so that the user can adjust the pitch angle of the display panel. For the convenience of users, some fixed seats are also provided with a lifting device, which can be set between the mounting plate and the slewing frame. As a whole, there is a sliding guide mechanism and a sliding positioning mechanism between the fixed part and the sliding part. The sliding positioning mechanism can be a constant force spring whose main body is installed on the fixed part and the outer end is connected to the sliding part, which can realize the liquid crystal panel up and down. Stepless positioning, but when a single constant force spring is used, the LCD panel may not rise and fall smoothly, and the spring torsion is easy to decay and affect the use.

The further technical scheme of the utility model is: a double-spring lifting mechanism for a liquid crystal display support, including a support frame fixed to the base, a lifting device for installing a liquid crystal panel, a slewing frame connecting the support frame and the lifting device, and the lifting device includes The lifting fixed seat and the lifting main body are slidably connected. The fixed force springs whose outer ends are connected to the lifting main body are fixed on the said lifting fixed seat. The fixed force springs include at least two; In the groove of the support frame and fixed by the screw passing through the top of the support frame downwards, the front end of the slewing frame is pivotally connected with the lifting and lowering fixing seat through a hinge; The main body of the fixed seat fixed to the connection part of the fixed seat; the two sides of the lifting main body are provided with chute, the two sides of the main body of the fixed seat are provided with lifting sliding blocks sliding in the chute, and the upper and lower ends of the chute have stop structures; The upper end of the main body of the fixed seat is horizontally fixed with at least two spring fixed seats, and each spring fixed seat is respectively seated with a constant force spring; the two sides of the main body of the fixed seat are provided with protrusions, and the lifting sliding block passes through the The grooves matched with the protrusions are installed on both sides of the main body of the fixing seat; the outer end of the constant force spring is folded outward and upward, and the lifting main body is provided with an opening for fixing by bending hooks.

The utility model advantage is:

1. The utility model adopts at least two constant force springs to position the liquid crystal panel for lifting and lowering, so that the sliding of the liquid crystal display is more stable during the lifting operation.

2. The utility model adopts at least two constant force springs, which can prolong the service life of the liquid crystal display bracket, reduce the torsion attenuation of the constant force springs, and delay the inaccurate or impossible positioning caused by the attenuation of the spring torsion.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment: as shown in Fig. 1 to Fig. 4, a double-spring lifting mechanism of a liquid crystal display stand includes a support frame 2 fixed to a base 1, a lifting device 4 for installing a liquid crystal panel, and a connection between the support frame 2 and the lifting device 4 The slewing frame 3, the lifting device 4 includes a lifting fixed seat 5 and a lifting main body 6 that are slidably connected. Included are two.

The rear end of the slewing frame 3 is inserted into the corresponding groove of the support frame 2 and is fixed to the support frame 2 by the screw 8 that passes through the top of the support frame 2 downwards. . Such a fixing method can make the display stand easy to disassemble, save time for online assembly, and is also convenient for users to assemble and disassemble by themselves.

The lifting fixing base 5 includes a fixing base connecting portion 52 connected with the slewing frame 3 and a fixing base main body 51 fixed with the fixing base connecting portion 52 by long screws.

Both sides of the lifting body 6 are provided with chute 61 , and the upper and lower ends of the chute 61 have stop structures 611 to prevent the lifting sliding block 511 from falling out of the chute 61 .
