Hole 322 is connect, setting slide bar connects long lumbar hole 312 and connecting hole 322.In the process that the length of first support and second support changes
In, slide bar is slided along long lumbar hole, and long lumbar hole can play the role of guiding, and slide bar can play a supporting role, and fix the chair back
Also stability with higher when frame is in longest state.
The side arm of 3 front end of chair back fixed frame and attachment base is hinged, the present embodiment it is as shown in Figure 3-Figure 5, fixed in the chair back
Upper end in the rotation direction of frame 3 is equipped with third limited block 13, and the second limited block 12 is located at the rotation of first support 31 simultaneously
Lower end on direction passes through the model of third limited block 13 and the second limited block 12 cooperation limitation chair back fixed frame 3 rotated upwardly and downwardly
It encloses.The linking arm 22 of chair back fixed frame 3 and seat fixed frame 2, which has, shares the second limited block 12 of limit, and chair back fixed frame 3 and company
Hinge joint between joint chair 1 and between seat fixed frame 2 and attachment base 3 is overlapped, and keeps the mounting structure of chair frame compact.
Two-stage chair back-rest inclination regulating mechanism is arranged in chair frame.As shown in figure 8, setting gradually the first bullet below chair back fixed frame 3
Property supporting element and roll adjustment handle 42,42 inclined shore chair back fixed frame 3 of the first elastic supporting member for supporting optical member and roll adjustment handle.By external force
Chair back fixed frame 3, which is rotated down, afterwards drives chair back reclining backward, while the first elastic supporting member for supporting optical member of extruding of chair back fixed frame 3 makes its hair
Raw deformation, the opposition of the first elastic supporting member for supporting optical member resets chair back fixed frame after cancelling external force, the chair back fixed frame
3, the first elastic supporting member for supporting optical member and roll adjustment handle 42 constitute first order chair back-rest inclination regulating mechanism.
Roll adjustment handle 42 includes rotary head, and the rotary head of roll adjustment handle 42 can be rotated around the fixed rotating fulcrum in a position,
First elastic supporting member for supporting optical member is limited between the circumferential edge of 42 rotary head of chair back fixed frame 3 and roll adjustment handle.The week of rotary head
Distance to edge to rotating fulcrum differs, in the rotation process of roll adjustment handle, the compressed degree of the first elastic supporting member for supporting optical member
It is different.
The first elastic supporting member for supporting optical member in the present embodiment includes the first spring 41, limit plunger 44 and fixed block 45, the first spring
41 upper end is limited by limit plunger 44, and first support is equipped with positioning protrusion 313 directed downwardly, limit plunger 44 be equipped with it is described
The card slot that positioning protrusion 313 cooperates, fixed block 45 are equipped with fixing groove, and the lower end of the first spring 41 is mounted on the fixing groove
In.Fixed block 45 is connected to the circumferential edge of the rotary head of roll adjustment handle 42, in 41 inclined shore chair back fixed frame of the first spring
First support 31.Above-mentioned first order regulating mechanism is set, and chair back fixed frame 3 can turn downwards around attachment base under external force
Dynamic, after it rotates a distance, chair back fixed frame 3 contacts to be further continued for rotating down with the second limited block 12.By
It is compressed between chair back fixed frame and roll adjustment handle in the first spring, by adjusting the contact between roll adjustment handle and fixing piece
When face, changeable first spring are located at original state by compression distance, so as to adjust power needed for rotating chair back fixed frame
Size.Since the chair back is mounted on the rear end of chair back fixed frame, exerting a force backward to the chair back can be such that chair back fixed frame 3 rotates down, from
And chair back reclining backward is driven, thus constitute first order chair back-rest inclination regulating mechanism.And it is fixed in first support along
The finger baffle 46 of the compression direction setting of one elastic supporting member for supporting optical member.
As shown in Figure 10 and Figure 11, chair back connector includes connecting bracket 54, and connecting bracket 54 and chair back fixed frame 3 are cut with scissors
It connects, and waist hole A323 is set to limit the range that connecting bracket 54 is rotated relative to chair back fixed frame 3 on chair back fixed frame 3；Chair
Back is mounted in connecting bracket 54, and the rotation of connecting bracket 54 drives reclining before and after the chair back；It is equipped in the front side of connecting bracket 54
Second elastic supporting member for supporting optical member, connecting bracket 54 backward reclining while the second elastic supporting member for supporting optical member can be made to deform, above structure structure
At second level chair back-rest inclination regulating mechanism.
Connecting bracket 54 in the present embodiment is mounted in second support 32, and waist hole A323 is also disposed at second support 32
On.
The second elastic supporting member for supporting optical member in the present embodiment includes connecting rod 52 and second spring 51, and 51 sets of second spring are connecting
The periphery of bar 52, the rear end of connecting rod 52 are fixed in second support 32 after passing through connecting bracket 54, and second spring 51 is limited
Between the front end and connecting bracket 32 of connecting rod 52.
