Description
Technical field
This utility model is related to a kind of lifting rotation resetting-mechanism of chair, the lifting positioning of more particularly to a kind of chair
Rotation and automatic reset mechanism.
Background technology
The species of chair is various, and most office is all using the rotating handrail with lift adjustment function now
Chair, this kind of armchair generally include foot rest, seat cushion, connect foot rest and the elevating mechanism of seat cushion, the backrest being located on rear side of seat cushion, position
Handrail in seat cushion both sides, the pulley for being arranged on foot rest bottom.Elevating mechanism with the height of regulating seat cushion, and can make the seat cushion can
Arbitrarily rotated with carrying out 360 degree.The pulley of foot rest bottom can be moved with Convenient chair.
Under normal circumstances, elevating mechanism is center of gravity positioned at the center of foot rest, when people is erectly sitting on chair
Substantially can fall in the center of foot rest, now the stationarity of chair is preferable.But, if people sit on cushion and incline leaned on
When on backrest, chair center of gravity will offset the center of foot rest, and now chair stationarity is poor, easily overturn, also, by
Hidden in people is bad under leaning seated position state, therefore under leaning seated position state, safety is bad.
For this purpose, some armchairs are just modified to the center of gravity of chair when design, by the center of gravity of chair to foot rest
Front side skew, so, when people sits to be leaned against on backrest into seat cushion or inclination, chair center of gravity returns to substantially the centre bit of foot rest
Put, so as to increase the stationarity under leaning seated position state.But, reality is found in use, as seat cushion is connected to elevator
Can be with 360 degree of any rotations on structure, it must sit into seat cushion from the front side of foot rest to be unable to warrantor, if seat cushion
What front openings turned to foot rest opens side or rear, people sit into fall when seat cushion deviate with the position of centre of gravity of chair larger, this
When be easily caused chair overturning.Therefore, existing elevating mechanism does not have the function in adjust automatically seat cushion orientation, actually used
When there is certain potential safety hazard.
Utility model content

Outer tube being protruded upward at the top of elevating lever, also including rotating pipe box, fixed pipe box, compression spring, roll tube set is set on the liter
Can be with elevating lever synchronous axial system on drop bar, fixed pipe box is connected on outer tube, and rotation pipe box and fixing pipe set have a pair each other
Opposed helical form contact surface；
Original state, compression spring produce the elasticity for making that roll tube set contact surface and fixing pipe set contact surface are close together
Power；
Elevating lever is rotated, rotation pipe box rotates and vertically away from fixed pipe box, the compression spring is oppressed
Make its elastic force increase；
Elevating lever is unclamped, compression spring release elastic force simultaneously promotes rotation pipe box and fixed pipe box vertically mutually to lean on
Closely, roll tube set drives elevating lever to rotate and returns to original state.
Among one preferred embodiment：The rotation pipe box is located in outer tube and can vertically slide along elevating lever.
Among one preferred embodiment：The rotation pipe box is located in outer tube and can vertically slide along elevating lever.
Among one preferred embodiment：The fixing pipe is set in outer tube and is located at roll tube set top, the fixation
Pipe box is set on elevating lever.
Among one preferred embodiment：The upper end of the fixed pipe box is provided with the shade for stretching out, and the shade covers institute
State the upper end open of outer tube.
Among one preferred embodiment：The fixed pipe box, the inner surface of rotation pipe box are provided with oil storage locating slot.
Among one preferred embodiment：The compression spring is arranged in outer tube and is located at below rotation pipe box.
Among one preferred embodiment：Also include that the thrust bearing being arranged on elevating lever, the compression spring are supported on and push away
Between power bearing and rotation pipe box.
Among one preferred embodiment：Also include that the inner tube being arranged in outer tube, said inner tube are supported on the thrust bearing
Lower section.
Compared with background technology, it has the advantage that the technical program：
Roll tube set contact surface and fixing pipe set contact surface fit together, and in the state of acting on without external force, utilize
The elastic force of compression spring makes roll tube set drive elevating lever rotation to return to original state, when the seat cushion of chair is connected to lifting
When on bar, it is possible to ensure in the state of chair is not used, seat cushion can be automatically rotated to initial orientation.

Specific embodiment
Fig. 1 to Fig. 4 is refer to, a kind of lifting rotation resetting-mechanism of chair of the present utility model, including be vertically arranged
Outer tube 10, the telescopic cylinder being movably arranged in outer tube, the telescopic cylinder include nesting together and relatively turnable axle
Core 20 and elevating lever 30.20 bottom of shaft core is connected with outer tube 10, protrudes upward outer tube 10 at the top of elevating lever 30；Elevating mechanism is also wrapped
Rotation pipe box 40, fixed pipe box 50, compression spring 60 is included, rotation pipe box 40 is set on the elevating lever 30 can be same with elevating lever
Step is rotated, and fixed pipe box 50 is connected on outer tube 10, and there are a pair helical forms opposite each other to connect for rotation pipe box and fixing pipe set
Contacting surface 42,52.
Original state, compression spring 60 is produced makes roll tube set contact surface 42 and fixing pipe set contact surface 52 be close together
Elastic force (as shown in Figure 2).
Elevating lever 30 is rotated, rotation pipe box 40 rotates, two contact surface 42,52 coordinates to be made to fix pipe box 50 and rotation pipe box 40
Vertically away from (as shown in Figure 4), now, the compression spring 60 increases its elastic force by compressing.
Remove external force and unclamp elevating lever 30, the release elastic force of compression spring 60 simultaneously promotes rotation pipe box 40 and fixed pipe box 50
Vertically close to each other, rotation pipe box 40 drives elevating lever 30 to rotate and returns to original state.
The rotation pipe box 40 is located in outer tube 10 and can be along 30 vertical slip of elevating lever.30 outer surface of the elevating lever sets
There are locating slot 32, the roll tube to be arranged with the fixture block 44 for being embedded into the locating slot；The fixed pipe box 50 is arranged on outer tube
In 10 and above rotation pipe box 40, the fixed pipe box 50 is set on elevating lever 30.The upper end of the fixed pipe box 50
The shade 54 for stretching out is provided with, the shade 54 covers the upper end open of the outer tube 10；The fixed pipe box 50, roll tube
The inner surface of set 40 is respectively equipped with oil storage grooves 56,46.
The compression spring 60 is arranged in outer tube 10 and is located at below rotation pipe box 40.Elevating mechanism also includes being arranged on
Thrust bearing 70 on elevating lever 30, the compression spring 60 are supported between thrust bearing 70 and rotation pipe box 40.Elevator
Structure also includes that the inner tube 80 being arranged in outer tube 10, said inner tube 80 are supported on below the thrust bearing 70.
It is to be appreciated that the compression degree of compression spring 60 is directly proportional to the anglec of rotation of elevating lever 30, bullet is compressed
When the degree of the compression of spring 60 reaches maximum, the maximum angle that corresponding elevating lever 30 can be rotated towards side.Therefore, it can lead to
The decrement of design compression spring 60 is crossed, the angle rotatable of elevating lever 30 is controlled.
The above, only this utility model preferred embodiment, therefore this utility model enforcement can not be limited according to this
Scope, i.e., the equivalence changes that is made according to this utility model the scope of the claims and description and modification, all should still belong to this practicality new
In the range of type covers.
