Limitation, generally require set chair entirety more simplify.And corresponding device is preferably set to be easy to participant opening
Can when recorded, and the chair back can carry out the reclining of low-angle to change the field-of-view angle of participant.Due to Conference Room
The problem of disposably needing to use substantial amounts of chair, therefore also needing to consider the carrying and storage of conference chair.
Utility model content
In order to solve the above problems, one of the purpose of this utility model is that provide one kind realizes chair by simple structure
Carry on the back the reclining governor motion of low-angle reclining regulation.
Another object of the present utility model is that the conference chair of low-angle reclining regulation can be carried out by providing a kind of chair back
In order to realize above-mentioned purpose, the utility model employs following technical scheme：
The reclining governor motion of the chair back, including cursor, shrapnel group and fixed block, one end of cursor are fixed on the chair back
On, the other end of cursor acts on the free end of shrapnel group, and the fixing end of shrapnel group is fixed in chair frame by fixed block.It is logical
Cross user makes shrapnel group bending realize that elevation angle of the chair back in smaller angle is adjusted to chair back force, is conveniently adjusted use
The sight of person.
As optimal technical scheme, the dynamic clamping head and quiet clamping head is shrapnel group, and shrapnel group includes multiple shell fragments being stacked.
Because the rigidity of shrapnel group is larger, shrapnel group remains to play the effect at support back after stress bending, cancels to the outer of the chair back
After power, shrapnel group, which is restored, drives the chair back to reset, and multiple shell fragments being stacked are used as into elastic supporting member for supporting optical member, easily manufactured, installation
It is simple in construction.
As optimal technical scheme, the free end of shrapnel group is connected multiple shell fragments by fastener, and fixed block is provided with upper
The slot of end opening, the fixing end of shrapnel group are inserted in the slot of fixed block.Multiple shell fragments are connected by fastener, make each shell fragment
Uniform force, it is spacing to shrapnel group by slot, it is easy for installation.
As optimal technical scheme, shrapnel group and fixed block are located in adapter sleeve, and fixed block is bolted on connection
The lower end of set, cursor are fixed on the top of adapter sleeve by bearing pin and pad.Reclining governor motion of the present utility model is installed
When, miscellaneous part is installed by immobilizing foundation of adapter sleeve, mounting structure is simple.
As optimal technical scheme, chair frame includes two pairs of front chair legs and rear chair leg, front chair leg and rear chair leg arranged in a crossed manner
For hollow tube, the upper end of the lower end insertion front chair leg of adapter sleeve.Coordinated by grafting and fixed, it is easy for installation, and from outside not
It is observed that specific attachment structure, makes the outward appearance of the chair with the reclining governor motion more neat and artistic.
As optimal technical scheme, the lower end of cursor is provided with inverted L-shaped abutting part, and the free end of shrapnel group is connected to this and supported
Socket part, and the vertical edge of abutting part is located at the front side of shrapnel group.Connection need not be set between cursor and the free end of shrapnel group
Structure is that the transmission that can be achieved between shrapnel group coordinates, i.e., can deform upon shrapnel group cursor force, after cancelling external force
Shrapnel group, which resets, to drive cursor to reset.
As optimal technical scheme, adapter sleeve is made up of left and right connecting plate and front side board, and side seal board is arranged on adapter sleeve
Fixed block and shrapnel group are limited in adapter sleeve by the left and right sides, side seal board.Fixed block and shrapnel group etc. can be on rear side of adapter sleeves
Load inside adapter sleeve, and these parts are limited in adapter sleeve by the side seal board of both sides.
As optimal technical scheme, the front side board on front side of fixed block with adapter sleeve offsets, the left and right sidewall of fixed block and company
The left and right connecting plates interior side contacts of female connector.What is typically the chair back applied due to user is active force backward, shrapnel group by
Active force backward is bent afterwards backward, and because the lower end of shrapnel group is fixed on fixed block, fixed block can be by shrapnel group to it
The active force forward applied, sets the front side of fixed block and the front side board of adapter sleeve to offset, the front side board of adapter sleeve can be shared
The active force of a part suffered by fixed block, the bulk strength of reclining governor motion can be strengthened.
As optimal technical scheme, the sheath of quality of rubber materials is coated with the outside of chair back-rest inclination adjusting part.Play protection
Effect.
A kind of conference chair, include the reclining governor motion of the chair back as described above.Low-angle reclining can be carried out with the chair back
The beneficial effect of regulation.
In summary, the reclining governor motion of the above-mentioned chair back has the advantages that：It can be realized by simple structure
Reclining in the low-angle of the chair back is adjusted, and the force size for only needing to adjust when user leans against the chair back backward can be real
The now reclining regulation to the chair back, using simple.
The conference chair of reclining governor motion with the above-mentioned chair back is equally with above-mentioned beneficial effect.
