The specific embodiment

Chair regulating device of the present utility model, its seat support and the chair back are to utilize adjusting device and can pivot be enclosed within the vertical rod of seat, and make the seat support and the chair back can pass through the tight bundle of adjusting device, and obtain fixing, and this each adjusting device all includes: a collar, two lock spiral shells, two pads, two control levers and one compress part, wherein, the collar cover is pulled in vertical rod, make one can supply seat support or chair back combination, the opposing party then has a breach, and respectively be extended with a pertusate fin in the breach both sides, after allowing two lock spiral shells and two pads can abut on the lateral surface of two fins respectively, utilize control lever to penetrate again and screw lock on the lock spiral shell, and free end can voltage supply to part pivot group, so, promptly finish the use form of this adjusting device, compress part one side again and be formed with an operating handle, then be formed with the service portion and a depressed part of a protuberance between the opposite side of the opposing party and pad respectively, thus, to obtain chair regulating device.

Further understand and understanding for having the purpose of this utility model, feature and effect, following conjunction with figs. is enumerated embodiment, and detailed description is as back:

At first, see also Fig. 1 to Fig. 4, its seat support (20) and the chair back (30) are to utilize adjusting device (40) and can be enclosed within the vertical rod (11) of seat (10) by pivot, and make the seat support (20) and the chair back (30) can pass through the tight bundle of adjusting device (40), and obtain fixing, and this each adjusting device (40) all includes: a collar (41), two lock spiral shells (42), two pads (43), two control levers (44) and one compress part (45), wherein, collar (41) cover is pulled in vertical rod (11), make one can supply seat support (20) or the chair back (30) combination, the opposing party then has a breach (411), and respectively be extended with a pertusate fin (412) in breach (411) both sides, after allowing two lock spiral shells (42) and two pads (43) can abut on the lateral surface of two fins (412) respectively, utilize control lever (44) to penetrate again and screw lock on lock spiral shell (42), and free end can voltage supply support part (45) pivot group, so, promptly finish the use form of this adjusting device (40), compress part (45) one sides again and be formed with an operating handle (451), then be formed with the service portion (452) and a depressed part (431) of a protuberance between the opposite side of the opposing party and pad (43) respectively.

The continuous Fig. 5 and shown in Figure 6 that sees also, during its actual use, can be according to user's height, build, and adjust the height of this seat support (20) and the chair back (30) voluntarily, when when adjusting, only need on operating handle (451), bestowing pull force, allowing and compressing part (45) to be the axle center with pivot group place, and toward inner rotary, service portion (452) breaks away from relatively, and do not compel to be against on the depressed part (431) of pad (43), collar (41) then can utilize breach (411) and elastic stretch slightly, advances tightly not restraint in vertical rod (11), and collar this moment (41) just can be in length travel in the vertical rod (11), the drive seat support (20) or the chair back (30) are adjusted its high and low position to take advantage of a situation, when treating that collar (41) is moved to the expection height, just operating handle (451) oppositely can be pulled, allow service portion (452) compel to be butted on the depressed part (431) of pad (43) once again, collar (41) is then tightly restrainted mutually with vertical rod (11), so, just can allow the seat support (20) or the chair back (30) maintain this adjusted height, take or by holding to be used to provide.

Again, the adjusting device (40) that is used to provide seat support (20) location can be used an alignment pin (46) again, one spring (47) and a capping (48), this alignment pin (46) also is provided with scalariform, behind the perforation (453) that makes its path rank pass compressing part (45), stretch out in again and compress part (45) inner face, big footpath then has a counter sink (461) on the rank, after allowing spring (47) energy down go into to fix, utilize the combination of capping (48) again, compress on the part (45) and make alignment pin (46) and spring (47) be fitted in, and vertical rod (11) outer wall hypomere is concaved with some locating holes (111) with respect to this side that compresses part (45), then has a through hole (413) on the collar (41), make when seat support (20) and be adjusted to desired height, and will compress part (45) and return when pulling, can make alignment pin (46) pass through hole (413), and snap into the locating hole (111) of relative altitude, to utilize the dual detent force of collar (41) and alignment pin (46), and take the user, when allowing weight all down act on the seat support (20), tight Shu Lidao deficiency still can not take place, and causes the phenomenon of seat support (20) landing downwards.

In addition, the vertical rod (11) of seat (10) is to establish to be up skewed, when seat support (20) and the chair back (30) when adjusting thereon, hypsokinesis angle with energy this seat of synchronous change (10), and vertical rod (11) top utilizes the block of the fixed block (12) of a tool handrail (121), and can prevent the seat support (20) and the chair back (30) when adjusting height, the phenomenon that has past top offset to go out produces.

By the structure of above-mentioned specific embodiment, can obtain following benefit:

What (one) its seat support (20) and the chair back (30) can be according to the users is different, and arbitrarily adjusts high and low position, allows this seat more suit measures to different persons, and takes relative comfort;

Only need to pull when (two) it is adjusted and compress part (45), just can finish rapidly, to obtain extremely convenient, the chair regulating device easily of an operation.

The above only is a preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this; Promptly the equalization of being done according to the claim scope of the utility model application generally changes and modifies, and all should still belong in the scope that claim of the present utility model contains.
