Abstract
The utility model provides a human engineering chair of working, belongs to the mechanical manufacturing technology field, includes to adopt chassis, chair frame, seat support, back and handrail to constitute, and chair frame both sides have a bracing piece respectively, and there is the handrail elevating system of parts constitutions such as uide bushing and lifter at the bracing piece top, has the handrail angular adjustment mechanism of parts constitutions such as swiveling wheel and ejector pin on the handrail. The during operation, the workman sits on the seat support, and back leans on in back department, and on two handrails were placed about respectively to the big arm of both arms, the health swung back occasionally that the back supports like this, and big arm passed through the handrail and supports when both hands were operated, can save physically effectively to can make the health keep comfortable state, the height and the angle of handrail can be adjusted. The utility model discloses solve the workman greatly and faced upward the production line work occasion work intensity of labour of body operation at needs, improved production efficiency.
Description
Technical field:
The utility model belongs to machinery manufacturing technology field, is a kind of seat.
Background technology:
Equipment generally will be sling by the assembling bottom machinery equipment, worker stands operates below equipment, the assembling of such as vehicle chassis and other production line workplace, due to the relation of position, during work, workman needs to take carry arm to lean back, labour intensity is large, works long hours very arduous, also affects operating efficiency.
Summary of the invention:
The technical problems to be solved in the utility model is that open one is applicable to industrial ergonomics work chair.
The scheme of the utility model technical solution problem adopts chassis, chair frame, seat support, backrest and handrail form ergonomics work chair, chassis is below chair frame, seat support, backrest and handrail are arranged in chair frame, chair frame both sides have a support bar respectively, support bar top is connected with vertical fairlead, elevating lever is had in fairlead, there is the positioning tooth be arranged above and below elevating lever middle and lower part, level below each positioning tooth, be inclined-plane above, fairlead has location key seat, location key seat external port has locking nut, location key seat is corresponding with positioning tooth position, pull bar is had in location key seat, on pull bar, cover has spring, there is alignment pin the inner of pull bar, contiguous block is arranged at the top of elevating lever, contiguous block there is the fixed axis of horizontal cross, there is axle sleeve at the two ends of fixed axis, the rear end of handrail is fixed on axle sleeve, fixed axis stage casing is connected with downward fixed bar, the bottom surface of handrail front portion has groove, groove is built with tapped swiveling wheel, push rod is installed with in swiveling wheel, push rod follower head withstands on fixed bar, push rod is anterior in swiveling wheel, and there is the external screw thread with swiveling wheel screw-internal thread fit.During work, workman is sitting on seat support, back leans against backrest place, the large arm of both arms is placed on two handrails in left and right respectively, back rest supports is had when leaning back like this, when both hands operate, large arm passes through arm supports, effectively can save muscle power, and the state that health keeps comfortable can be made, according to the diverse location of workpiece and the difference of workman's height build, the height of handrail can be adjusted by elevating lever, upwards elevating lever is pulled during adjustment, now the inclined-plane of positioning tooth makes alignment pin exit, action is stopped after reaching correct position, pull bar makes alignment pin reinsert in positioning tooth by spring, elevating lever is stoped to fall, handrail then rests on this height, when needing decline handrail, pull out pull bar, alignment pin leaves positioning tooth, elevating lever falls, reach releasing lever after correct position, alignment pin reinserts positioning tooth, the angle of handrail can be adjusted as required, rotate swiveling wheel, change the position of swiveling wheel and push rod, push rod, fixed bar, fixed axis and elevating lever relative position are fixed, swiveling wheel moves forward, then handrail is that axle rotates counterclockwise with fixed axis, and the front portion of handrail is higher than rear portion.
In order to adjust the height of seat support, lifting air lever is installed between chassis and chair frame, by lifting air lever adjustment height of seat.
In the bottom on chassis, universal wheel and leg disc are installed, can the position of moved seat easily by universal wheel, during work, the pin of leg disc is extended, make universal wheel leave ground, by leg disc support chassis, ensure that seat is stablized.
In addition, backrest angle is adjustable, according to work requirements free adjustment backrest angle, can improve work comfort.
Above backrest, adjustable headrest can be installed, adjustable waist pillow be installed between backrest and seat support, improve work comfort further.
The utility model significantly solves workman at the production line workplace labor intensity needing to face upward body operation, and enhance productivity, structure is simple, easily operates.
