Fixture block 911.External member of the bull stick of chair back back side at the top of third connecting plate makes the chair back free with respect to third connecting plate
Rotation；Then the round bar of chair back back side is passed through into third arcuate socket, and then limits the rotational angle of the chair back, realize limit；Then,
Torsional spring is packed into bull stick, by the interaction of torsional spring and the fixture block of the chair back, so that the chair back is not in the case where by other external force
It overturns forward, until round bar is in contact with the bottom interior wall of third arcuate socket, is sat up straight in this way, not influencing people, and in people
When back relies on the chair back, the chair back can be bonded with more preferably angle with back, improve comfort.In addition, being needed in people
Lunch break, people lean on back backward, and when head is placed in subsequent desk, back imposes active force to the chair back, drives the chair back
Overcome the torque of torsional spring to act on to turn over, to be preferably bonded, support the back of people, so that people can be with comfortable lunch break.
As shown in Figure 14, Figure 16-Figure 21, specifically, bracket 921 is fixedly connected with chair back control switch 95；Chair back control
Switch 95 includes first rotating shaft 951, the first fixing seat 952 of the first groove of band 9521, first movement seat 953；First rotating shaft 951
One end be equipped with first handle 9511,951 other end of first rotating shaft is connected to the first fixing seat 952 and can be with respect to the first fixing seat
952 rotations, the right side of first rotating shaft 951 is fixed with convex block 9512；First movement seat 953 is set to the first of the first fixing seat 952
In groove 9521, the first limiting slot 9534 is equipped on rear side of the right end of first movement seat 953, the first limiting slot 9534 is provided with first
Elastic component, the both ends of the first elastic component are abutted against with the first limiting slot 9534, first rotating shaft 951 respectively, first movement seat 953
It is fixed with the first fastener 9533 on front side of right end, first movement seat 953 is provided with for accommodating first rotating shaft 951 and convex block 9512

951 third pilot holes 9421 wearing, corresponding with the first pilot hole 9412.First elastic component includes 9542 He of the first spring
First T-piece 9541, the both ends of the first spring 9542 are connected to the inner wall of the first limiting slot 9534, the first T-piece 9541 respectively,
First T-piece 9541 is recessed inwardly the opening for being formed with and matching, abutting against with first rotating shaft 951.First T-piece can be by cylinder
Body and cube composition, at T-shaped with shape, the first spring pocket is set to cylindrical body, and abuts with cube.
The course of work of chair back control switch is as follows: when first rotating shaft 951 rotates counterclockwise, convex block 9512 and third are logical
The medial surface in hole 9531 abuts against, and during rotation, and convex block 9512 rotates synchronously with first rotating shaft and pushes first to move
Dynamic seat 953 overcomes the elastic force of the first elastic component to be moved to the left, and the first fastener 9533 is moved to the second guiding from the first bayonet 9414
So that supporting element 94 moves down in hole 9413.When needing to move up supporting element, first rotating shaft is rotated clockwise, it then will support
Part moves up, until the first fastener and the first bayonet are in same level；Convex block is being lost to the impetus of first movement seat
In the case where power, first movement seat is moved right due to the elastic effect of the first elastic component, while the first fastener is with first movement
Seat moves to right, and is moved in the first bayonet, and be in contact with the first bayonet, realizes detent, and supporting element is fixed.Guide pad
9211 be cylindrical body, can open up connecting hole, and guide pad is fixedly connected with limited block 9216 by connecting hole, screw, by third
Connecting plate and bracket stable connection, so that third connecting plate can only be moved along the direction of the first pilot hole；In addition to this, it limits
Block 9216 can directly be socketed on guide pad 9211, or be fixed using welding manner.
Refering to Figure 20, bracket includes two linking arms 9215 and T shape fixed plate 9214, and the both ends of T shape fixed plate are fixed respectively
It is connected to one end of two linking arms, the other end of linking arm is fixedly connected with seat board.
Limit hole 9532 is offered on front side of the left end of first movement seat 953, the first fixing seat 953 is provided with positioned at limit hole
9532 gag lever post 9523, gag lever post 9523 and the first fixing seat 952 are integrally formed, by the setting of gag lever post and limit hole,
The distance being moved to the left to first movement seat limits.So that first movement seat can only be moved left and right in the first groove without
The first fixing seat can be detached from.
As shown in Fig. 7-Figure 11, specifically, locking device 5 includes second the 51, second elasticity of shaft with second handle 511
Second fixing seat 55 of part 52, the second Mobile base 53 and the second groove of band 552；The outer peripheral surface of second shaft 51 is integrally formed with arc
Shape block 512；Second Mobile base 53 is set in the second groove 552 and opposite second fixing seat 55 is slided, outside the second Mobile base 53
Side is equipped with the second fastener 56, and the second fastener 56 is movably connected on the first arcuate socket 431, and the inside of the second Mobile base 53 is equipped with second

Two elastic components contact with each other with the second shaft.Second shaft is then passed through to the first circular hole 422 of the second connecting plate, and by second
Connecting plate is fixedly connected with the second fixing seat.In the rotation of the second shaft, arc block is rotated with it, and pushes the second Mobile base gram
It takes the second elastic component and moves linearly to its active force along the two sides inner wall of the second fixing seat, so that the second fastener is from preceding bayonet
Or the position of rear bayonet is moved to the first arcuate socket, this moment, desktop can be switched between forward-lean state and horizontality.And
When second shaft is rotated backward, the second Mobile base is after losing arc block to its motive force, only by the second elastic component pair
In the case where its active force, reversed linear movement occurs for the second Mobile base, and the second fastener can be made by the first arc hole site
Be moved to preceding bayonet or rear bayonet position, when the second fastener is located at preceding bayonet and rear bayonet, then cannot switch the leaning forward of desktop,
Horizontality.That is, the locking device plays control action, the position of the second fastener is controlled, so that desktop will not be random
Inclination.
Fig. 4 and Fig. 5 are please referred to, the lateral surface of table leg 3 is fixed with protection cap 8；Second fixed plate is fixedly connected with protection cap,
Setting protection cap inside, provides the encapsulated by structures such as locking device, pneumatic buffer to protective effect, and increase aesthetic feeling.It protects
