Technical field

The utility model relates to a kind of stool, particularly a kind of the adjustable stool of backrest.

Background technology

Stool in the prior art, for example the bar desk stool of using such as the bar, specialize in stool for repairing cycle that motor repair trade uses or the like and have following shortcoming jointly, because seat backrest and saddle constitute one each other, therefore can't carry out the adjusting of horizontal direction separately to the seat backrest, user's sitting posture and comfort level is construed as limiting; Again since the shelves that are used for leg rest only in a certain azimuth configuration, therefore when saddle had been rotated to the position of the shelves that leave leg rest, user's both feet just can't be shelved, and equally seat were brought inconvenience with the person.

Summary of the invention

Top priority of the present utility model is will provide a kind of can carry out upper and lower, forward and backward adjusting to the seat backrest and use the sitting posture that improves the user and the stool of comfort level.

Another task of the present utility model is to provide a kind of leg rest not to be subjected to the stool of orientation restriction.

For top priority of the present utility model is finished in embodiment, technical scheme provided by the utility model is, a kind of stool, it comprises by the collaborative base that constitutes of the arm of a plurality of each tool roller, be arranged on the acting cylinder of base central authorities, be fixed on the cylinder post holder of the cylinder column top of acting cylinder, the handle that being used on cylinder post holder control the valve of cylinder post is hinged, be fixed on saddle and a seat backrest and a gear that is positioned at base top on the cylinder post holder, characteristics are: it also includes a seat backrest guiding mechanism, be bound up on the saddle, on the fixing present backrest guiding mechanism of described seat backrest.

For another task of the present utility model is finished in embodiment, technical scheme provided by the utility model is that described gear is a disc, is hubbed on the top of base.

Seat backrest guiding mechanism described in the utility model comprises lower limiting board, first adjusts knob, elastic support, the upper limit plate, second adjusts knob, the back fixation of the saddle base plate of lower limiting board and saddle, and the middle part of this lower limiting board constitutes first bracket chute, first adjusts the first bracket chute position that knob is configured in lower limiting board, first tie down screw of its upper end is fixed with the saddle base plate after passing the elastic support of inserting in first bracket chute, one end of elastic support offers first screw slot, the other end offers second screw slot, first screw slot matches with first tie down screw, and second screw slot matches with second second tie down screw of adjusting knob, the upper limit plate fixes with the seat backrest, the middle part constitutes second bracket chute, and described second second tie down screw of adjusting knob is passing the upper limit plate, fix with the seat backrest behind second screw slot of elastic support.

Acting cylinder described in the utility model is the air spring cylinder.

One of advantage of the present utility model can be regulated according to making upper and lower, forward and backward adaptability the seat backrest, can improve user's comfort level; Two, discoidal gear can satisfy 360 ° comprehensive leg rest requirement.

Description of drawings

Accompanying drawing is a structure chart of the present utility model.

The specific embodiment

In the accompanying drawings, the base 1 that provides is that arm 11 unitary set by a plurality of cloth form, the end hub setting roller 111 of each arm 11, and the central authorities of base 1 constitute a through hole, are used for fixing with acting cylinder seat 22 at the through hole position for acting cylinder 2.Described discoidal gear 7 also hub setting on acting cylinder seat 22.As embodiment, the acting cylinder of being selected 2 is the air spring cylinder, the end of its cylinder post 21 and cylinder post holder 3 are fixing, and the back side of the saddle base plate 51 of cylinder post holder 3 usefulness screws and saddle 5 is fixed, be installed with a hinged ear 31 on cylinder post holder 3,4 on handle is hinged on this hinged ear 31, and terminal corresponding valve 211 places at cylinder post 21 of this handle 4, when acting on valve 211, then can make 21 actions of cylinder post when pulling handle 4.Compound fixed saddle pad 52 on the saddle base plate 51.

Be intended to make a backrest 6 to embody seat backrest guiding mechanism 8 upper and lower, forward and backward adjusting as the utility model pushed away, the both sides of its lower limiting board 81 are fixed with the back side of screw and saddle base plate 51, and first bracket chute 811 of the thickness of the elastic support 83 that will mention below being used to compensate is processed at the middle part of lower limiting board 81.First adjusts that knob 82 revolves and on first bracket chute 811, and fixes with nut and saddle base plate 51.Because an end of elastic support 83 is that the lower end is shaped on first screw slot 831 in advance, therefore after the end inserting of the elastic support 83 of tool first screw slot 831 was in first bracket chute 811, first first tie down screw 821 of adjusting knob 82 just passed first screw slot 831 and the lower end of elastic support 83 is located.When knob 82 is adjusted in counterclockwise operation first, the locking that first tie down screw 821 is removed elastic support 83, this moment, elastic support 83 just can be realized forward and backward displacement, thereby drive the seat backrest 6 that is located at elastic support 83 upper ends and do forward and backward displacement, as soon as after determining suitable degree of displacement, then adjust knob 82 to the clockwise direction turn, the locking that first tie down screw 821 is implemented elastic support 83 lower ends with first.The function of second screw slot 832 that the upper end of elastic support 83 is offered is identical with first screw slot 831.The both sides of upper limit plate 84 are fixing with the backup plate 61 of seat backrest 6 with screw 842, the middle part of upper limit plate 84 processes equally or claims to be shaped one second bracket chute 841, be used for compensating the thickness of the upper end of elastic support 83, adding when second second tie down screw 851 of adjusting knob 85 hole passed under the state of packing ring 8511 on the upper limit plate 84 and and then pass second screw slot 832 until pass backup plate 61 usefulness nuts 611 fixing after, just realized making fixing of a backrest 6 and elastic support 83 upper ends.Revolve second when adjusting knob 85 when contrary, the locking that second tie down screw 851 is removed seat backrest 6, just can comply with seat backrest 6 and need displacement up or down this moment, thereby realize the upper and lower Height Adjustment to seat backrest 6, finish as soon as adjust, adjust knob 85 to clockwise direction turn second again.

By foregoing description as can be known, seat backrest 6 forward and backward mobile ultimate ranges depend on the flute length of first screw slot 831; And upper and lower mobile amplitude peak depends on the flute length of second screw slot 832.Especially can satisfy different personnel or same personnel's sitting posture requirement by adjustment seat backrest 6, so can bring comfortable impression for the user; Leg rest when the gear 7 of disc type can supply the user in any direction.
