Lifting supporting frame used for display device

Abstract

The invention relates to a lifting supporting frame used for a display device. The lifting supporting frame is used for supporting the display device and comprises a U-shaped base, a sliding support and constant-force spring assemblies, wherein the contour the U-shaped base is approximately in a U shape, and the sliding support is arranged in a U-shaped opening of the U-shaped base and capable of ascending and descending. The lifting supporting frame is characterized in that the constant-force spring assemblies are arranged on the left side and the right side correspondingly; the static ends of the constant-force spring assemblies are fixed to the upper left end and the upper right end of the U-shaped opening of the U-shaped base correspondingly; and the movable ends of the constant-force spring assemblies are fixed to the left outer side and the right outer side of the sliding support correspondingly. The lifting supporting frame is smaller in occupied space and especially suitable for the arrangement of a lifting mechanism in the lifting supporting frame of the display device with the U-shaped base, a narrow space can be sufficiently utilized for installing a lifting force balancing mechanism, and a user feels quite smooth during lifting; and in addition, the structure is quite simple, assembling is convenient, and the cost is reduced.

Description

technical field [0001] The invention relates to a lifting support frame for a display, in particular to a lifting support frame with a display such as an all-in-one desktop machine, a POS machine, and a tablet computer (the display referred to in the present invention includes a display or a display screen that displays a movable picture, Including all-in-one desktop machines, POS machines, and tablet computers, etc., hereinafter referred to as monitors or display screens or screens). Background technique [0002] The actual use of the display generally requires a support frame to support and adjust the viewing angle, and many of them need to be adjustable in height. For the existing display support frame technology closest to the present invention, see the utility model patent liftable device, patent number ZL201420179972.7. However, its mechanism is complex. It uses plastic pull ropes and multiple fixed pulleys to pull the constant force spring. There are many parts, many...

Problems solved by technology

However, its mechanism is complex. It uses plastic pull ropes and multiple fixed pulleys to pull the constant force spring. There are many parts, many friction points, and large friction resistance. It cannot be fully applied; the plastic rope has a limited lifespan. Because the rope is made of plastic, it will creep under stress even at room temperature. For a long time, the length of the rope will be longer and the elasticity will change, resulting in a change in the bearing capacity and a further change in the hand feel. Difference

At the same time, due to the large number of parts, the cost increases and the assembly is troublesome.
