This utility model provides an expandable study chair, belonging to the field of chair technology. The expandable study chair includes a seat cushion, a backrest disposed on the upper side of the seat cushion, an adaptive push rod disposed inside the backrest, an angle adjustment component fixedly connected to the front end of the adaptive push rod, a first rotating shaft rotatably connected inside the adaptive push rod, and a lumbar support fixedly connected to the circumferential surface of the first rotating shaft. This utility model, through adaptive lumbar support, can automatically adjust according to the user's body shape and sitting posture, providing optimal lumbar support, reducing discomfort caused by prolonged sitting, while maintaining the natural curve of the spine, effectively preventing spinal curvature and other related health problems caused by poor posture.

This utility model discloses an adjustable backrest cushion, comprising: a base; a main connecting piece, the tail end of which is connected to the base; an upper main piece, located at the upper part of the head end of the main connecting piece; a lower main piece, located at the lower part of the head end of the main connecting piece; and a transmission module, connected to the main connecting piece, the upper main piece, and the lower main piece. When the upper main piece is subjected to pressure and retracts, the transmission module transmits power to move the lower main piece forward; conversely, when the lower main piece is subjected to pressure and retracts, the transmission module transmits power to move the upper main piece forward. This utility model has the following beneficial effects: Self-triggering adjustment: Utilizing the body's own weight to drive the mechanism, it achieves automatic feedback that "the further you lean back, the stronger the lumbar support." Real-time support force balance: Under rigid mechanical reverse linkage conditions, it achieves dynamic tracking and adjustment of the cushion's support position, adapting to the spinal curvature of different individuals.

The utility model relates to the field of spine curvature measurement technique, proposes a kind of spine curvature measuring instrument, including: bottom plate, support frame, fit board, sliding block, transmission mechanism, recording mechanism, moving mechanism and lifting mechanism, support frame is slidably connected at the top of bottom plate, fit board is equipped with two, two fit boards are all fixedly connected at the top of bottom plate, sliding block is slidably connected in support frame, transmission mechanism is set on sliding block, for measuring the curvature of spine, recording mechanism is set on support frame, for recording curvature information, moving mechanism is set on support frame, lifting mechanism is set on bottom plate, for driving support frame to move up and down, by above-mentioned technical scheme, solved the measurement mode in this kind of measurement mode in relevant technology needs medical staff to complete measurement manually, when medical staff is busy, this kind of measurement mode is more time-consuming and laborious, and simultaneously, reduce the work efficiency of medical staff.
