The utility model discloses a laborsaving adjustment mechanism is provided in display support, including antifriction bearing 1, antifriction bearing 1 be connected with the second end of the screw thread slider 3 of display support, antifriction bearing 1's axial set to the axial direction along perpendicular to screw rod 4, antifriction bearing 1's outer rolling surface contact with connecting piece 6 down for pass through screw rod 4 adjust screw thread slider 3 when reciprocating, antifriction bearing 1 along connecting piece 6 rolls down.

Specifically, the rolling bearing 1 may contact with an inner wall of the lower connecting member 6, and when the threaded slider 3 is adjusted to move up and down by rotating the screw rod 4, the threaded slider 3 is in rolling friction on the inner wall of the lower connecting member 6 through the rolling bearing 1. The force of the mechanical spring or the gas spring is directly transmitted to the lower connecting piece in contact with the mechanical spring or the gas spring through the rolling bearing on the threaded sliding block, and compared with the existing mechanical spring or the gas spring, the force of the mechanical spring or the gas spring is generated by the sliding friction of the threaded sliding block directly propping against the screw rod.

Sliding friction force calculation formula: f1 ═ μ F

The rolling friction force calculation formula is as follows: m ═ N × μ k ═ f2 × r; f2 ═ N ═ μ k/r

Generally, the friction coefficient mu between the existing screw and the thread sliding block is approximately equal to 0.15; the utility model discloses rolling friction coefficient mu k of structure is appurtenant to 0.05mm, simultaneously the utility model discloses a bearing radius r ═ 5 mm.

In the case of using the same mechanical or gas spring, N ═ F; F2/F1 (N × μ k/r)/(μ × F) ═ μ k/(μ × r) ═ 0.07, which corresponds to a reduction in the frictional force of 7% of the original.

Therefore, under the same acting force of the mechanical spring and the gas spring, the utility model discloses the produced total frictional force of rotatory screw rod of mechanism is little.
