Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the invention will be further described.
Embodiment 1：As shown in figs. 1-11, a kind of collapsible small backrest, including connecting rod a1, movable connecting rod group 2, connection
Bar b3, backrest brace 5, connecting rod c6, connecting rod d7；
Described movable connecting rod group 2 and connecting rod a1 constitute the under(-)chassis of small backrest, and three movable connecting rod groups 2 are vertical simultaneously
Rank in the bottom of small backrest, the two ends and centre of movable connecting rod group 2 are equipped with connecting hole, and three connecting rod a1 are horizontal respectively
Through the two ends of three connecting rod groups 2 and the connecting hole of centre, two connecting rod b3 respectively with the both sides of the connecting rod a1 of front end
Vertical connection, three connecting rod c6 are vertically connected with the connecting rod a1 of rear end respectively, and two tops of connecting rod b3 are by connection
Bar d7 is connected, and is connected by two connecting rod d7 respectively between three middle parts of connecting rod c6, between top, movable connecting rod group
2 middle part is foldable, is respectively have a backrest brace 5 on connecting rod b3.
Further, described movable connecting rod group 2 includes motion bar a11 and motion bar b14, steel bar 12, motion bar a11
One end is provided with movable span a10, and the other end is provided with movable span c13, and motion bar b14 one end is provided with movable span b15, and the other end is provided with work
Dynamic hole c13, connecting rod a1 are through the movable span c13 above motion bar a11 and motion bar b14 by motion bar a11 and motion bar b14
Link together, movable span a10 is vertically connected with connecting rod c6, movable span b15 is vertically connected with connecting rod b3, divide on steel bar 12
Fixing groove and chute are not provided with, the one end on motion bar a11 and motion bar b14 near movable span c13 is respectively equipped with projection, living
Projection on lever a11 and motion bar b14 is bolted connection sheet 17 respectively above, is connected to above motion bar a11
Connection sheet 17 is rotatably connected in the fixing groove on steel bar 12, i.e.,：The connection sheet 17 being connected to above motion bar a11 can not
It is relative to slide, can only relatively rotate, the connection sheet 17 being connected on motion bar b14 is bolted on sliding block a18, sliding
Block a18 is arranged on the chute on steel bar 12In 19 and can be along slide, when the sliding block a18 on motion bar b14 slides into chute19 outermost end（That is high order end in Fig. 4）When, motion bar a11 and motion bar b14 connects into a cross bar, on motion bar a11
Sliding block slides into chute19 innermost end（That is low order end in Fig. 4）When, motion bar a11 is folded with motion bar b14.
Movable span c 13 is that connecting rod 11 and 14 has above, is then penetrated in the two movable spans by other connecting rods
Connecting rod 11 and 14 is set to link together, now the movable span 13 above the two bars of motion bar a 11 and motion bar b 14 is weight
Stack, motion bar a 11 and motion bar b 14 is linked together by movable span c 13, it is possible to achieve fold.By inciting somebody to action
Connecting rod a 1 will be living through the insides of movable span c 13 of movable span a 10, movable span b 15 and connection motion bar a and motion bar b
Lever group 2 is assembled into small backrest bottom.
Further, the connecting rod d7 and three connecting rod d7 on connecting rod c6 tops on two described connecting rod b3 tops
Between connected by two fix bars 9, the bottom inside of fix bar 9 is provided with chute, be respectively arranged at two ends with spherical linkage 20, it is sliding
GrooveSliding block b22 is inside installed, spherical linkage 20 includes spherical linkage end 21, connection sheet 17, spherical linkage end 21 and connection sheet
17 are bolted together, as a complete spherical linkage 20, to ensure fix bar energy large rotation.One
Spherical linkage 20 is fixed on the one end of fix bar 9, it is impossible to which mobile, another spherical linkage 20 is fixed on above sliding block b22, when small backrest
When without folding, the spherical linkage 20 being connected to above fix bar 9 and sliding block b22 is separately fixed at the company before and after small backrest
On extension bar d7, to increase the stability of small backrest, prevent small backrest from collapsing forwards, backwards and fall apart.It is fixed when small backrest will be folded
The operation principle of bar 9 is similar with the operation principle of motion bar group 2, chuteIt is strip chute, length realizes fix bar 9 enough
Pack up, sliding block b22 is from the one end of fix bar 9（I.e. away from one end of irremovable fixed spherical linkage 20 in fix bar 9,
That is high order end in Fig. 8）Slide to the other end（I.e. near one end of irremovable fixed spherical linkage 20 in fix bar 9, Ye Jitu
Low order end in 8）, fix bar 9 is rotated down, along with the cooperation of motion bar group 2, fold up small backrest.Increase and fix
Bar 9 can be such that small back frame structure more stablizes.
Further, in order to people can more comfortably carry on the back small backrest, backrest is installed between two described connecting rod b3
Back of the body cloth 4.
Further, it is described be connected to connecting rod d7 between connecting rod c6 tops in the middle of system have back of the body rope 8, after small backrest
A back of the body rope 8 is fastened in the centre of the connecting rod d 7 of face atop part, and the tobacco leaf of harvesting is placed on small backrest the inside, will the back of the body after piling
Rope 8 is tied up to above the connecting rod d7 before small backrest, and back of the body rope 8 can both tie down tobacco leaf so that tobacco leaf will not during the back of the body send
Fall down, and held two parts before and after small backrest to a certain extent, it is ensured that small backrest will not collapse backward.
Further, described connecting rod d7 is respectively arranged at two ends with hinge seat 23, and hinge seat also is provided with above sliding block b22
23, spherical linkage 20 is placed in above hinge seat 23, easy for installation, and it is firm to connect.
This small backrest of folding is positioned in backrest by by tobacco leaf, without by the way of embracing out, subtracting significantly
The artificial damage caused to tobacco leaf is lacked.For than larger tobacco leaf, left and right two end portions are not kept off
Firmly, thus tobacco leaf beyond backrest come part can just allow its be positioned over backrest outside, tobacco leaf will not be folded to, reduce again to cigarette
The damage of leaf.Tobacco leaf is transported with small backrest, out entrucking is more laborsaving by tobacco leaf armful compared to rising directly.
Specific embodiment of the invention is explained in detail above in conjunction with accompanying drawing, but the present invention is not limited to above-mentioned reality
Example is applied, in the ken that those of ordinary skill in the art possess, can also be on the premise of present inventive concept not be departed from
Various changes can be made.
