Abstract

The present invention discloses a lifting device of a blood collection chair, comprising a chassis arranged at the ground, a top rack which is connected with the seat of the blood collection chair and a lifting mechanism which drives the top rack to lift towards the chassis. The lifting mechanism comprises a low voltage electric handspike and an air spring. The axial lead of the low voltage electric handspike and the axial lead of the air spring are parallelly arranged at the level direction. The low voltage electric handspike has the characteristics of safe use, low noise, good using environment and little interference to the outside. The air spring is always under the compressed state. When the low voltage electric handspike is extended outwards, the air spring takes power-assisted effect towards the low voltage electric handspike; when the low voltage electric handspike retracts inwards, the air spring can eliminate the gap among each component inside the low voltage electric handspike, which ensures that the descending process of the top rack is more stable.

Description

Technical field [0001] The invention relates to a lifting device for adjusting the height of the seat of a blood sampling chair relative to the ground, so as to adapt the body of a blood donor to the height requirement of a blood separator. Background technique [0002] The existing lifting device of the blood collection chair usually includes two types, one is a mechanical transmission type, and the other is a hydraulic transmission type. The mechanical transmission adopts gear transmission, which has complex structure, heavy appearance, high noise and poor stability. The hydraulic transmission type is relatively stable and has a large power-to-mass ratio, but the oil is easy to spill due to tilt or vibration during transportation, and the hydraulic components are expensive. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a blood sampling chair lifting device that is safe to use, low in noise, and stable in operation. ...
