Description

Technical Field

[0001] This utility model relates to an adjustable support frame structure for televisions or computers used in homes or offices. Background Technology

[0002] Existing adjustable support stands for televisions and computers used in homes or offices are divided into two types: fixed height and adjustable height. Adjustable support stands offer numerous conveniences depending on the usage environment and user. Achieving a simple structure, stable support, easy adjustment, and aesthetically pleasing appearance is a continuous improvement goal for the industry.

[0003] The existing technology uses a lifting structure such as the invention patent CN114190692B entitled "Lifting Table".

The fixed outer rod and the lifting inner rod are retractably connected via the outer rod sliding sleeve and the inner rod sliding sleeve.

[0008] The adjustable support frame structure is equipped with a table adjustment device;

[0009] The table adjustment device includes: a pair of lifting control screws, a lifting nut, a bevel gear pair, and an adjustment shaft;

[0010] The adjustment shaft is rotatably fixed on a pair of fixed outer rods in the telescopic support rod. The driving gear of the bevel gear pair is respectively set on the adjustment shaft inside the fixed outer rod. The lifting nut is fixedly connected to the lifting inner rod through the inner rod sliding sleeve in the telescopic support rod. The lifting control screw is rotatably fixed inside the fixed outer rod. The lifting control screw is threadedly connected to the lifting nut threaded inside the lifting inner rod, and one end is fixedly connected to the driven gear of the bevel gear pair.

[0011] The advantages of this invention are: simple structure, convenient adjustment, stable support, and low cost. It is especially suitable for use in offices or homes for televisions, computers, or for studying.

[0012] The present invention will now be described in detail with reference to the accompanying drawings. Attached Figure Description

[0018] An adjustable support frame structure includes: a support platform 5, a support base 6, and a telescopic support rod, wherein the support platform 5 and the support base 6 form a support structure via the telescopic support rod.

[0019] The retractable support rod includes: a fixed outer rod 1-1, a lifting inner rod 1-2, an outer rod sliding sleeve 1-3, and an inner rod sliding sleeve 1-4. The fixed outer rod 1-1 is fixedly connected to the outer rod sliding sleeve 1-3, and the lifting inner rod 1-2 is fixedly connected to the inner rod sliding sleeve 1-4. The fixed outer rod 1-1 and the lifting inner rod 1-2 are retractably connected via the outer rod sliding sleeve 1-3 and the inner rod sliding sleeve 1-4.

[0020] The adjustable support frame structure is equipped with a table adjustment device;

[0021] The table adjustment device includes: a pair of lifting control screws 2-1, a lifting nut 2-2, a bevel gear pair 2-3, and an adjustment shaft 2-4.

[0022] The adjusting shaft 2-4 is rotatably fixed on a pair of fixed outer rods 1-1 in the telescopic support rod. The driving gears of the bevel gear pair 2-3 are respectively set on the adjusting shaft 2-4 inside the fixed outer rod 1-1. The lifting nut 2-2 is fixedly connected to the lifting inner rod 1-2 via the inner rod sliding sleeve 1-4 in the telescopic support rod. The lifting control screw 2-1 is rotatably fixed inside the fixed outer rod 1-1. The lifting control screw 2-1 is threadedly connected to the lifting nut 2-2, which is threadedly fixed inside the lifting inner rod 1-2. One end is fixedly connected to the driven gear of the bevel gear pair 2-3.

[0023] When in use, the outer rod sleeve 1-3 and the inner rod sleeve 1-4 form a guide for the lifting and sliding of the fixed outer rod 1-1 and the lifting inner rod 1-2, and at the same time play a sealing role.

[0024] By adjusting the rotation of shaft 2-4, the driving gear in bevel gear pair 2-3 is driven. The rotation of the driving gear drives the driven gear in bevel gear pair 2-3, the lifting control screw 2-1, and the lifting nut 2-2 to move the lifting inner rod 1-2 up and down along the lifting control screw 2-1, thereby adjusting the support height between the support platform 5 and the support base 6.

[0025] The threaded connection between the lifting control screw 2-1 and the lifting nut 2-2 not only enables the lifting adjustment function, but also provides stable support for the support platform 5 and the support base 6.

[0026] In this embodiment of the invention, a manual control handle 3-1 is provided at one end of the adjusting shaft 2-4. The adjusting shaft 2-4 is rotated in both directions by the manual control handle 3-1 to achieve the lifting and lowering adjustment function.

[0027] In this embodiment of the invention, the adjusting shaft 2-4 is coaxially connected to the dual-output shaft motor 4-1. The dual-output shaft motor 4-1 drives the adjusting shaft 2-4 to rotate in both directions, thereby achieving the lifting and lowering adjustment function.
