Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this description, as long as but be all subject to the protection of Patent Law in right of the present utility model.

Embodiment: the adjusting part of relative position between a kind of seat support and the chair back, comprises pedestal 1, pedestal 1 comprise for activity install chair base frame 11 bracket 101, relatively with bracket 101 be fixed for activity the support of seat back frame 12 be installed.

Bracket 101 has two parallel sides and forms flange respectively to extension, is considered as seat support prerotation vane 22, and seat support prerotation vane 22 length direction level is to extension; Chair base frame 11 has two parallel sides, and this dual-side has the seat support gathering sill 21 be slidably socketed in corresponding seat support prerotation vane 22 respectively; Seat support prerotation vane 22 and seat support gathering sill 21 form the seat support guidance set for guiding chair base frame 11 activity direction; Seat support prerotation vane 22 also can be arranged the slide block 221 be slidably socketed in seat support gathering sill 21; The limited block 211 for slide block 221 of conflicting also is respectively equipped with at the two ends of seat support gathering sill 21.

A seat support prerotation vane 22 has some breach wherein, be considered as positioning recess 31, positioning recess 31 is arranged along the activity direction of chair base frame 11; Location bull stick 32 is rotatably connected in the respective side of chair base frame 11, the middle part of location bull stick 32 is arranged in the direction being parallel to this side of chair base frame 11, chair base frame 11 inside is goed deep in one end of location bull stick 32, and fall within corresponding positioning recess 31, thus realize the relative fixing of chair base frame 11 and bracket 101, be provided with at this side of chair base frame 11 and be suitable for locating the deep opening 111 of bull stick 32, the other end of location bull stick 32 stretches out, and is formed and is convenient to apply external force with the handle of rotational positioning bull stick 32; The rotation direction of location bull stick 32 is that Vertical dimension rotates, and is also provided with elastic component 33, is generally torsion spring, thus makes location bull stick 32 have the trend of upwards rotating all the time, namely have the trend falling within positioning recess 31 between location bull stick 32 and chair base frame 11; Positioning recess 31, location bull stick 32, elastic component 33 are formed and regulate chair base frame 11 to slide the seat support positioning component of amplitude.

Seat support guidance set and seat support positioning component are formed for level between chair base frame 11 and bracket 101 to the seat support adjustment structure of relative position.

The back side that support comprises is along the rear end of chair base frame 11 to front extreme direction in skewed obliquely, and support comprises the link 1021 be fixedly connected with bracket 101, the stock 1022 be fixedly connected with link 1021.

The both sides of stock 1022 are respectively arranged with chair back gathering sill 41, and the both sides of seat back frame 12 have the chair back prerotation vane 42 be slidably socketed in corresponding chair back gathering sill 41 respectively; Chair back gathering sill 41 and chair back prerotation vane 42 form the chair back guidance set guiding seat back frame 12 activity direction; Chair back gathering sill 41 is skewed obliquely along the rear end of chair base frame 11 to front extreme direction.

In the surperficial both sides of seat back frame 12 SCCP connection-oriented part 1021, be respectively equipped with multiple locating slot 51, locating slot 51 is arranged along the activity direction of seat back frame 12; Keeper 52 is provided with between stock 1022 and connector 1021; The two ends of keeper 52 have the positioning convex 521 that can fall within corresponding locating slot 51; Stock 1022 has the space 54 of being inserted in keeper 52, and the degree of depth in space 54 is greater than the thickness of keeper 52; Bolt 53 is had to be screwed into keeper 52 outside stock 1022, the radial rotating trend of keeper 52 is the sidewall restriction in space 54, thus can the axially-movable with the rotational action of bolt 53 in space 54, and then positioning convex 521 can be made to depart from locating slot 51 or fall within locating slot 51, so that the position of adjusting back framework 12; The knob 55 being convenient to external force rotating bolt 53 is provided with in one end of bolt 53; Locating slot 51, keeper 52, bolt 53 form the chair back positioning component for locating seat back frame 12.

Chair back guidance set, chair back positioning component are configured for the back regulating mechanism of adjusting back framework 12 level and Vertical dimension relative position.

As this embodiment is applied to height-adjusting swivel chair, bracket 101 is also arranged the control lever 6 for starting gas lever switch.
