Abstract
The utility model provides a hydraulic control swivel chair which is provided with a two oil cylinders. One cylinder is an erect oil cylinder used for controlling a chair seat to rise and fall, and the other is a crossing oil cylinder used for regulating the pitching angle of the backrest. With the two oil cylinders, the seat height and pitching angle of the backrest fitting to the requirement of the user can be selected to enable the user to take a break for eliminating fatigue while working at optimal position and in optimal posture.
Description
The utility model relates to a kind of swivel chair of the usefulness of handling official business, and especially can control the swivel chair of seat support lifting and backrest luffing angle.
The swivel chair of Chu Shouing all is to make the seat support lifting by screw rod in the market, needs to rotate seat support, is very much trouble, and does not generally possess the function of adjusting the backrest luffing angle.
In order to remedy above-mentioned deficiency, the utility model provides a kind of can control the seat support lifting easily, can adjust the swivel chair of backrest luffing angle simultaneously again.
For achieving the above object, the solution that the utility model adopts is that two hydraulic jacks are set in the seat support bottom, one makes the seat support lifting, be provided with piston in the cylinder, spring, piston rod, the setting oil cylinder of sealing gasket and sealing ring, another makes backrest conversion luffing angle, be provided with valve in the cylinder, valve rod, spring, the oil cylinder that lies across of sealing gasket and sealing ring, two oil cylinders are equipped with control crank respectively, by the extrusion effect of handle to oil cylinder piston bar or valve rod, and the break-make by sealing gasket control oil cylinder oil circuit, and then the pitching action of the lifting of control seat support or backrest.
Drawing of the present utility model is described as follows:
Fig. 1 is the front schematic view of hydraulic control work swivel chair,
Fig. 2 is the side view of hydraulic control work swivel chair,
Fig. 3 is the structural representation of setting oil cylinder,
Fig. 4 is the structural representation of oil cylinder of lying across.
Below in conjunction with drawings and Examples the utility model is done further more detailed explanation.
Fig. 1 and Fig. 2 mainly express hydraulic control work swivel chair by backrest 1, seat support 2, base 3, erect oil cylinder 4 and the oil cylinder 5 that lies across is formed, and express two oil cylinders and respectively have control crank 6 and 7.
Fig. 3 expresses the structure of erectting oil cylinder 4, when the people sits on the work swivel chair and moves control crank 6, because piston rod 8 is depressed, leave sealing gasket 11 and will open by the oil circuit 9 of piston rod 8 and piston 10 hollow spaces, make oil in the oil cylinder 4 get into the lower chamber 13 of oil cylinder 4 through oil circuit 9, at this moment spring 12 is compressed, and seat support 2 falls in company with oil cylinder.To be suitable for oneself work height the time, unclamp control crank 6, so oil circuit 9 is closed under the effect of spring 12, oil stops to flow, the position of seat support also just has been fixed.14 and 15 is sealing ring among the figure.
Fig. 4 expresses the structure of the oil cylinder 5 that lies across, it is used for adjusting the luffing angle of backrest 1, when pulling control crank 7, during by the valve rod 17 in the steel ball 16 extrusion oil cylinders 5, oil circuit 18 just is opened, lean against strength on the backrest 1 owing to be subjected to human body, force the oil in the oil cylinder 5 to be pressed against right-hand chamber 19 along oil circuit, at this moment spring 20 is compressed, and backrest 1 is to layback, by the time unclamp control crank 7 during proper angle, steel ball 16 is got away, so sealing gasket 21 is shut the oil circuit on the valve 22, oil stops to flow, and backrest 1 also just has been parked in this position.For making backrest 1 recover the origin-location, pull handle 7 once more, open oil circuit 18, because of unable being added on the backrest 1 at this moment by steel ball extruding valve rod 17, so squeezed at the oil of 19 li of the effect bottom right chambers of spring 19 and to get back to original chamber, backrest 1 is got back to the origin-location.During release handle 7, backrest 1 also just is fixed on the origin-location again.23 is sealing ring among the figure, and 24 is support.
