It can easily be viewed with bending over.
In conjunction with Fig. 4, Fig. 5, Figure 11, described be fixed on bookshelf bottom frame 50 side plate one 51 bottom surface and the side that is socketed
The lead screw 57 for driving side plate lifting is equipped between 2 52 bottom surface of plate, 57 quantity of lead screw is two, is respectively used to wear bookshelf
The side plate on 50 both sides of bottom frame, specifically, one end of lead screw 57 have been interference fitted a bearing, and lead screw is interference fitted side plate one
In circular hole on 51 bottom surfaces, the other end of lead screw 57 is connected in the trapezoidal thread hole in the middle part of 2 52 bottom surface of side plate, and 57 turns of lead screw
Kinetic energy enough pushes moving up and down for side plate 2 52；The bookshelf bottom frame 50 is equipped with the gear shaft 501 of driving lead screw rotation, described
Connection is engaged by bevel gear between gear shaft 501 and lead screw 57, the gear shaft 501 is driven by handwheel 6, is achieved in, and is turned
Start wheel 6 can drive lead screw rotation so that side plate 2 52 moves up and down.
The utility model bookshelf when in use, is rotated by 6 rotational driving gear axis 501 of handwheel, and then drives lead screw 57
Rotation so that side plate 2 52 moves up and down, since rope capacity is fixed, and be unfolded and shrink two states in bookshelf
Under, wirerope is in tensioned state, and therefore, when side plate 2 52 moves up and down, being fixed on wirerope on side plate 2 just be will drive
The folding and unfolding of whole wirerope, and side plate is just completed expansion or is shunk under the drive with certain degree of hardness wirerope.
Specific use process is as follows: bookshelf is unfolded-passes through the rotation of 6 rotational driving gear axis 501 of handwheel, and then drives silk
The rotation of thick stick 57；Side plate 2 52 is pushed to move upwards, so that the distance between side plate one and side plate two increase (since wirerope is solid
2 bottom of side plate is scheduled on so the wirerope between 2 bottom of 1 bottom of side plate and side plate is pulled up)；And wirerope was originally in completely taut
Tight state, after the wirerope between two bottom of one bottom of side plate and side plate is pulled up, the upper rigid castors of side plate two and three bottom of side plate
Distance between the lower rigid castors in portion reduces, and drives side plate three to rise under the action of wirerope, the upper fixation of three top of side plate
Castor between the lower rigid castors of four bottom of side plate at a distance from reduce, under the action of wirerope drive side plate four rise, side plate
Four top upper rigid castors between the lower rigid castors of five bottom of side plate at a distance from reduce, drive side under the action of wirerope
Plate five rises, the upper rigid castors of the top of side plate five between the lower rigid castors of six bottom of side plate at a distance from reduce, in wirerope
Under the action of drive side plate six to rise the rise for completing entire bookshelf, bookshelf is fully deployed at this time, and wirerope, which is still within, to be tightened
(stress total length is constant always for wirerope in the whole process for state；Castor on side plate is all fixed；Side plate two sides
There is corresponding guide groove, can only be moved up and down under force along guide groove direction).
Bookshelf shrinks-rotates backward the rotation of 6 gear shaft 501 of handwheel, and the rotation of lead screw 57 pushes side plate 2 52 to transport downwards
It is dynamic so that the distance between side plate one and side plate two reduce (since wirerope is fixed on 2 bottom of side plate thus 1 bottom of side plate and
Wirerope between 2 bottom of side plate shortens)；Between the lower rigid castors of three bottom of upper rigid castors and side plate of the top of side plate two away from
From increase, side plate three is driven to decline under the action of wirerope, under the upper rigid castors and four bottom of side plate of three top of side plate
Distance between rigid castors increases, and drives side plate four to decline under the action of wirerope, the upper rigid castors of four top of side plate with
Distance between the lower rigid castors of five bottom of side plate increases, and drives side plate five to decline under the action of wirerope, five top of side plate
Upper rigid castors between the lower rigid castors of six bottom of side plate at a distance from increase, under the action of wirerope drive side plate six under
The decline that drop completes entire bookshelf is shunk.
The utility model Extensible book-shelf can freely adjust height by elevator, be convenient for librarian and student
Take book, and guide groove is set on bookshelf lateral board mechanism both sides, is successively arranged rigid castors along guide groove inner and outer wall,
By the lead screw of two sides, successively wear rigid castors wirerope drive lifting lateral board mechanism synchronize equidistant movement down on the whole,
Realize that flexible and expansion, the structure novel of bookshelf are easy to operate.
And bookshelf partition is arranged in the utility model between each pair of opposite side plate, bookshelf partition by crankshaft by being connected to
Left door assembly with hinge and glass in right hand and left partition and right belt hinge partition composition together, further, bookshelf partition front and rear sides are respectively equipped with vertically
Angle between the baffle of left door assembly with hinge and glass in right hand and left partition and right belt hinge partition, the baffle and ground of upper layer bookshelf partition less than 90 °,
Angle between the baffle and ground of lower layer's bookshelf partition is greater than 90 °, in order to give one suitable angle of reader, is unlikely to high
The book at place is not seen, and the book needs of lower bend over to check.Extensible book-shelf bottom is also equipped with universal wheel, thus can be easy and convenient
Entire bookshelf is shifted.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this
The principle of utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various change
And improvement, these various changes and improvements fall within the scope of the claimed invention.The utility model requires protection scope
It is defined by the appending claims and its equivalent thereof.
