Description

Otorhinolaryngological clinic chair

Technical field

This utility model relates to a kind of patient chair, especially a kind of otorhinolaryngological clinic chair, and it is used for the department of otorhinolaryngology diagnosis and treatment of various big hospital and medical institutions.

Background technology

The inside of existing patient chair is fully by driven by motor, and its frame for movement is gear or worm gear, worm screw form, and the outside then forms by iron plate welding back.Its major defect is: one, noise is big; Two, behind the life-time service, since gear wear, the mechanical performance instability; Three, service life is short; Four, with iron plate welding chair frame, external form is not attractive in appearance, easily gets rusty, sealing-off etc.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of low noise, safe and reliable, long service life, department of otorhinolaryngology patient chair aesthetic in appearance.

The technical scheme in the invention for solving the above technical problem is: this patient chair comprises interconnected headrest, backrest, handrail, seat support, extension arm foot, step and base, its construction features is that base is provided with hydraulic control device, hydraulic control device comprises interconnected backrest oil cylinder, oil cylinder, oil pump, fuel tank, reversal valve, manual switch and foot switch up and down, wherein oil cylinder, oil pump, fuel tank and reversal valve are positioned on the base up and down, and the backrest oil cylinder is positioned at seat support.

Backrest described in the utility model, handrail, seat support, extension arm foot, step and base are ironcasting.

Manual switch described in the utility model is positioned on the backrest, and foot switch is placed on the ground.

Oil pump described in the utility model is the miniature oil pump of low noise.

Reversal valve described in the utility model is that hydraulic pressure connects valve more.

Also be provided with rotary disk and lock on the base described in the utility model.

Handrail described in the utility model links to each other with seat support by the handrail movable rod.

Backrest described in the utility model is provided with backing cushion, and seat support is provided with seat cushion.

This utility model compared with prior art has following beneficial effect: 1, backrest, seat support and hanging feet arm etc. adopt ironcastings, use reliable, handsome in appearance, cost is low; 2, adopt hydraulic control device to the lifting of patient chair with face upward (lying) and sit and control, not only noise is low, bearing capacity is big, also long service life, safety and sanitation; 3, adopt miniature oil pump of low noise and hydraulic pressure to connect valve more, have volume little, control advantage easily; 4, press button adopts low tension, can dually control, not only can be manual, but also feet controllable, safe and reliable.
