End stretches out the second transverse slat 28 and is equipped with the first bevel gear 31, and the second shaft 32 is equipped with above screw rod 30, and the second shaft 32 passes through
Bearing is horizontally arranged on drawing board containing box 1, and the second umbrella that connection is engaged with the first bevel gear 31 is equipped in the second shaft 32
Gear 33,32 other end of the second shaft stretch out drawing board containing box 1 and are equipped with rotating handle 34, are threaded with slide on screw rod 30
35, slide 35 is slidably connected with the second slide bar 29, and pawl 27 is hinged on slide 35.
Guardrail mechanism includes two grooves 36 being opened on parcel shelf 16, two grooves 36 and two third sliding slot guide rails 17
It corresponds, is equipped with cross bar 37 above groove 36, multiple fender rods 38,38 court of fender rod are hinged between cross bar 37 and groove 36
One end of direction guiding rail sliding block 19 is hinged with push rod 39, and 39 other end of push rod and guide rail slide block 19 are hinged.
Blend stop mechanism includes two the 4th sliding slot guide rails 40 being fixed on 2 lower end surface of drawing board ontology, the 4th sliding slot guide rail
The blend stop 41 that can be slided in the 4th sliding slot guide rail 40 is equipped between 40, upper protruding block 21 is fixed on the end face of the first transverse slat 23
Third transverse slat 42 is hinged with telescopic rod 43 on third transverse slat 42, and 43 upper end of telescopic rod and blend stop 41 are hinged, and drawing board ontology 2 tilts
When, telescopic rod 43 can release 41 part of blend stop, form one of rib in 2 bottom of drawing board ontology.
First strip sliding block 5 is supported and is blocked to 3 bottom Shi Huiqi of first sliding groove guide rail, and drawing board ontology 2 rises to most at this time
Eminence, and parcel shelf 16 is in the position vertical with 1 front panel of drawing board containing box.
First lifter plate 8 drops to can be resisted when contacting with bucking ladder 14 by bucking ladder 14, and drawing board ontology 2 drops at this time
Lowest part, drawing board ontology 2 completely storage with drawing board containing box 1 in, and parcel shelf 16 be in it is parallel with 1 front panel of drawing board containing box
Position.
Connector 20 is the connector 20 with certain bending angle, 20 both ends of connector when parcel shelf 16 is expanded to level
In same level.
2 upper end of drawing board ontology is equipped with handle 44.
When drawing board ontology 2 is accommodated in drawing board containing box 1 completely, guide rail slide block 19 is on third sliding slot guide rail 17 away from groove
36 farthest one end, the at this time inclination of fender rod 38 are accommodated in groove 36.
Bucking ladder 14 is isosceles trapezoid platform 14, and supporting leg 15 is in decline by being open after the inclined-plane of bucking ladder 14 guiding
Drawing board containing box 1 is stretched out in place's inclination.
The working principle of the invention: in use, first adjusting lockable mechanism, two lockable mechanisms control drawing board ontology 2 respectively
Raising and lowering, screw can control drawing board ontology 2 rising rotating handle 34, rotating handle 34 drive the second shaft 32, the second umbrella tooth
The 33, first bevel gear 31, the rotation of screw rod 30 are taken turns, slide 35 converts the rotary motion of screw rod 30 to and moves along a straight line and with pawl
27 rise, and the no longer locked ratchet 26 of pawl 27, therefore the direction of rotation of the ratchet 26 of two lockable mechanisms is on the contrary, control drawing board sheet
The pawl 27 for the lockable mechanism that body 2 declines will not block ratchet 26, can then pull handle 44, drawing board ontology 2 is pulled out,
Drawing board ontology 2 drives the second lifter plate 12 and the first lifter plate 8 to rise, and the second strip sliding block 7 slides in second sliding slot guide rail 4
To allow the first lifter plate 8 steadily to rise, the second rack gear 9 on the first lifter plate 8 drives Knucle-gear 10 to rotate, Knucle-gear
10 drive the first rack gear 6 and the decline of the first strip sliding block 5, and supporting leg 15 declines together with the first strip sliding block 5, and supporting leg 15 exists
It is tilted after the guiding of bucking ladder 14 by opening when decline and stretches out drawing board containing box 1, while the first slide bar 24 is with the first lifting
Plate 8 rises together, will drive one when the first transverse slat 23 on lower protruding block 22 resists lifting slider 25 with rising, lifting slider
25 successively move with follower link 20, guide rail slide block 19, and guide rail slide block 19 slides at spring 18 in third sliding slot guide rail 17
When start compressed spring 18 and push 16 outward turning of parcel shelf, continue to rise with lifting slider 25, spring 18 continuation compressed,
To allow connector to continue to rise, connector 20 can push parcel shelf 16 by guide rail slide block 19 and third sliding slot guide rail 17
Rotation to the position concordant with horizontal plane, guide rail slide block 19 pushes multiple fender rods 38 upright by push rod 39, cross bar 37, at this time
First strip sliding block 5 is supported and to 3 bottom of first sliding groove guide rail and is caught by, and drawing board ontology 2 rises to highest point at this time, and four
Supporting leg 15 stablizes support whole device, can begin to use, and controls the pawl for the lockable mechanism that drawing board ontology 2 declines at this time
27 block ratchet 26, to prevent drawing board ontology 2 from declining；
The setting of Damping hinge 13 can in order to adjust the angle of drawing board ontology 2, when adjusting the angulation change of drawing board ontology 2,
Telescopic rod 43 will push blend stop 41, one of rib be formed in 2 bottom of drawing board ontology, consequently facilitating placing picture on drawing board ontology 2
Paper prevents drawing paper from falling；
When needing to store drawing board ontology 2, the rotating handle 34 that can control the decline of drawing board ontology 2 is screwed, rises to pawl 27 not
The position of ratchet 26 can be blocked, so that Knucle-gear 10 be allow to rotate, the first lifter plate 8 declines, the first strip sliding block 5 and support
Leg 15 rises, and will drive its decline when the first transverse slat 23 on upper protruding block 21 is contacted with lifting slider 25, lifting slider 25 is drawn
Follower link 20, guide rail slide block 19 are mobile, and guide rail slide block 19 drives third sliding slot guide rail 17, parcel shelf 16 to be reset to drawing board storage
Case 1, guide rail slide block 19 drive the inclination of fender rod 38 to be accommodated in groove 36 by push rod 39, cross bar 37；
When needing to withdraw Mobile drawing board, the rotating handle 34 that control drawing board ontology 2 can rise can be reversely screwed, is pawl 27
The position that can block ratchet 26 is dropped to, in this way when lifting handle 44, ratchet 26 can block pawl 27, avoid the first lifting
Plate 8 and drawing board ontology 2 are suggested drawing board containing box 1.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it
It is interior.
