Description

Chair seat of doctor's chair

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to a seat of a doctor seat.

Background

It is known that when a doctor performs an examination or treatment operation for a long time, physical fatigue is likely to occur, and if the fatigue of the limb cannot be relieved, the operation is unstable, and the result of the treatment or examination is directly affected.

Currently, for a doctor seat, the doctor seat comprises a seat, a seat and a walking wheel assembly, wherein the adopted seat can only be lifted up and down or can not be adjusted, so that the seat can not be supported at a proper angle and position when a doctor has a rest or works, and the common seat can not meet the requirements of work or rest due to the difference of the physique of the doctor.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide an improved seat for a doctor seat.

In order to solve the technical problems, the invention adopts the following technical scheme:

the seat of the doctor seat comprises a seat part with a base and a cushion, a chair part with a backrest and a cushion, and a seat rod, wherein the base comprises a fixed seat, a sliding seat arranged on the fixed seat in a sliding way along the front-back direction of the fixed seat, a seat plate arranged on the sliding seat, the cushion is arranged on the seat plate, the seat part also comprises a turnover mechanism arranged between the sliding seat and the seat plate to drive the seat plate to turn around the horizontal direction, the backrest comprises a lower leaning rod with the lower end part in butt joint with the sliding seat, an upper leaning rod which rotates with the lower leaning rod and is movably regulated along the length direction of the lower leaning rod, the cushion is arranged on the lower leaning rod or/and the upper leaning rod, and when the upper leaning rod and the lower leaning rod are relatively rotated and folded, the cushion and the seat plate are relatively close and are attached up and down; the seat rod can relatively stretch to implement up-and-down lifting adjustment of the seat part.

Preferably, the fixing seat is provided with a sliding rail extending along the front-rear direction, the sliding seat comprises a seat body arranged on the sliding rail in a sliding manner, a control arm connected with the seat body and capable of being locked relative to the fixing seat, and a mounting seat arranged on the seat body, the seat plate is arranged on the mounting seat, and the turnover mechanism is arranged in the mounting seat. This arrangement facilitates assembly of the slide.

According to a specific and preferred aspect of the present invention, the mounting seat includes a seat bucket formed with an opening facing upward, a connecting rod fixed to the seat body, a seat cover provided in the seat bucket and having a seat cushion abutting against the connecting rod, and the seat plate is pivotally connected to an upper portion of a front end portion of the seat bucket by a horizontally extending pivot. Thus, the seat board can close the seat cavity hopper, and the butt joint of the seat cavity hopper and the seat body is convenient.

Preferably, a sliding groove arranged from top to bottom is formed at the front end part of the seat cavity hopper, and the turnover mechanism comprises a sliding block arranged in the sliding groove in a sliding way, a connecting module fixed at the rear part of the seat plate, a supporting rod with two end parts rotatably connected between the sliding block and the connecting module, and a locking piece for locking the sliding block and the seat cavity hopper relatively. Thus, the angle by which the seat plate is tilted about the pivot can be implemented by manipulating the position of the slider.

Further, the stay bar is a telescopic rod and is an air cylinder, an oil cylinder or an electric cylinder. Thus, the position of the sliding block can be controlled by further changing the length of the stay rod, so that the seat plate presents a required angle.

According to yet another specific and preferred aspect of the present invention, an inner bracket is further provided in the bowl, and the tilting mechanism further includes a top bracket assembly provided between the front and rear portions of the seat pan and mounted on the inner bracket. Further improving the supporting effect provided by the seat board.
