Abstract
The utility model relates to a folding book shelf on desks, which comprises a base, rotary supporting rods 1, a rotating shaft 2 and a torsion spring, wherein, the rotary supporting rods 1 which are connected shoulder to shoulder form a piano key distribution mode, the rotating shaft 2 is supported on the base which comprises a fixing frame and a bracket which is hinged with the fixing frame, and after the bracket is opened rotationally, the bracket can form a supporting surface with the fixing frame; the fixing frame comprises a transverse rod which is distributed parallelly with the rotating shaft 2. The utility model has the advantages of small size of a base entity and material saving, the utility model which can be folded without pressing the torsion spring in addition, can be realized, etc.
Description
The utility model relates to a kind of bookshelf that is supported on the desk, particularly a kind of desk-top folding bookcase, and it can be used for placing books or other book shape goods (as CD box, video cassette, cassette for recording tape).
The utility model designer applied for once that a key name was called the utility model patent of " desk-top bookshelf " (application number is 94215876.8), should " desk-top bookshelf " form by base, rotation pole, rotating shaft and torsion spring etc., because base is a flat cuboid, volume is bigger, not only consumptive material, consumption worker, increase production cost, and easy to carry and folding for making, need to be depressed by force to fit with base by the open rotation of torsion spring pole, operation is inconvenience extremely, and the torsion spring fatiguability damages.
The purpose of this utility model is to overcome weak point of the prior art, and provides a kind of base volume less, need not oppress the desk-top bookshelf that torsion spring can realize that bookshelf is folding separately.
The purpose of this utility model realizes by following approach.
Desk-top folding bookcase, comprise base, rotate pole, rotating shaft and torsion spring, rotation pole is suffered shoulder to shoulder connecing and is the key distribution, shaft support is on base, its structural feature is: base include decide frame and with decide behind hinged and its Unscrew of frame can with decide frame and form the support of bearing-surface, decide to comprise in the frame cross bar with the shaft parallel distribution.
The purpose of this utility model can also reach by following approach.
The structure of support can be such: it comprise two with cross bar exist together mode on the bearing-surface and the pole that is hinged on the cross bar both ends respectively and opens, close along said bearing-surface rotation.
The structure of support also can be such: it comprises two to be hinged on the pole at cross bar both ends respectively with the mode of cross bar spatial vertical.Simultaneously, decide to have on the frame limited block that a kind of pole extreme position that it sets and cross bar are combined into said bearing-surface.
Decide to comprise in the frame that two are distributed in rotation pole both sides and the guard bar affixed with crossbar end respectively, and the structure of support also can be such: support comprises two corresponding hinged poles with two guard bars.
Can also comprise in the support one be connected across between two poles and with the bar of striding of cross bar space parallel.
In sum, the utility model has following advantage compared to existing technology: base is hinged to by the bar rod-shaped member, not only the entity volume is little, economize material, and change and oppress the folding mode that rotates pole and torsion spring in the prior art by force, need not oppress torsion spring separately, by folding of base self to realize the portable of whole bookshelf, it is extremely convenient to operate, and also can or not deposit the fatigue damage torsion spring because of folding portable, thereby prolongs the service life of bookshelf.

Below we carry out more detailed description to the utility model in conjunction with the accompanying drawings.Embodiment 1:
With reference to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, desk-top folding bookcase, form by base, rotation pole 1, rotating shaft 2 and torsion spring 3 etc., numerous rotation poles 1 connect and are the key distribution, base comprise decide frame and with decide behind hinged and its Unscrew of frame can with decide frame and form the support of bearing-surface, wherein decide frame and form by cross bar 41 and straight-bar 42, cross bar 41 and rotating shaft 2 are parallel and by touching tossing about in rotation pole 1 lower end, two straight-bars 42 are fixed in cross bar 41 both ends respectively, and rotating shaft 2 is bearing on the straight-bar 42; Support by two with exist together mode on the bearing-surface and corresponding hinged with two straight-bars 42 respectively of cross bar 41, and can form along the pole 51 that said bearing-surface rotation is opened, closed.Pole 51 should can not interfered with the pole 51 that guarantees to fold less than 1/2 cross bar, 41 length to the distance of pole 51 distal ends mutually with the hinged central point of straight-bar 42.Torsion spring 3 one end bearings are in the groove that rotation pole 1 is tossed about, and the other end then is bearing on cross bar 41 upper surfaces.
It is same as the prior art that present embodiment is not stated part.Embodiment 2:
With reference to accompanying drawing 4, accompanying drawing 5 and accompanying drawing 6, desk-top folding bookcase, comprise base, rotate pole 1, rotating shaft 2 and torsion spring 3, base comprise decide frame and with decide behind hinged and its Unscrew of frame can with decide frame and form the support of bearing-surface, deciding frame is made up of cross bar 41 and guard bar 43, two guard bars 43 are distributed in respectively and rotate pole 1 both sides, and it is affixed with cross bar 41 ends, rotating shaft 2 is bearing on the guard bar 43, guard bar 43 epireliefs are made a limited block 44, by the hinged pole 51 of rotating shaft 2 and guard bar 43 because the restriction of limited block 44 has two extreme positions.Be extreme position under the duty shown in Fig. 4, Fig. 5, Fig. 6, at this moment, the bookshelf bearing-surface is formed in the bottom surface of two poles 51.By shown in Figure 4, the pole 51 that turns clockwise, make its once more with limited block 44 by touching, make pole 51 parallel with guard bar 43 and rotation pole 1 basically, at this moment, pole 51 is in the extreme position under the folded state.Support is by pole 51 and be connected across between two poles 51 and with the bar 52 of striding of cross bar 41 space parallels and form.
It is identical with embodiment 1 that present embodiment is not stated part.Most preferred embodiment:
With reference to accompanying drawing 7 and accompanying drawing 8, desk-top folding bookcase, form by base, rotation pole 1, rotating shaft 2 and torsion spring 3 etc., base include decide frame and with decide behind hinged and its Unscrew of frame can with decide frame and form the support of bearing-surface, deciding frame is made up of cross bar 41 and the guard bar 43 that is fixed in cross bar 41 two ends, rotating shaft 2 is bearing on guard bar 43 bottoms, guard bar 43 tops and pole 51 are hinged, it is corresponding hinged with two guard bars 43 to have two poles 51, and support is by two poles 51 and be connected across between two poles 51 and the stride bar 52 parallel with cross bar 41 formed.Guard bar 43 is tossed about and is had groove 431, the pole 51 after folding can in this groove 431 of retraction.
It is identical with embodiment 1 that present embodiment is not stated part.
