Detailed description of the invention
Embodiment one
Seeing Fig. 1, a kind of Foldable type storage rack provided according to this utility model, including left and right two bearing frames erect
1,2, couple between two bearing frames 1,2 and have two parallel-crank mechanisms.One of them parallel-crank mechanism is with left side
Bearing frame 1 is frame, including four side links 3 ~ 6 parallel to each other being hinged on the bearing frame 1 of left side.Another parallel four limits
Shape mechanism is with right side bearing frame 2 as frame, including four side links 7 ~ 10 parallel to each other being hinged on the bearing frame 2 of right side.
Relative with a frame connecting rod of two parallel-crank mechanisms, is the public connecting rod 11 of two parallel-crank mechanisms.With
This public connecting rod 11 is axis of symmetry, and two parallel-crank mechanisms are symmetrical.Side link 3 and side link 7 constitute the one of shelf
Layer article-retaining shelf, by that analogy, side link 4,8 constitutes a layer article-retaining shelf, and side link 5,9 constitutes a layer article-retaining shelf, side link 6,10
Constitute a layer article-retaining shelf.As in figure 2 it is shown, the distance between arranged on left and right sides bearing frame 1,2 is along with two parallel-crank mechanisms
Deform and change.
Referring also to Fig. 1, Fig. 3, has been slidably connected a slide block 12 on public connecting rod 11, and slide block 12 is hinged with two
Strut 13,14.Wherein a support bar 13 is hinged with a side link 4 in left side parallelogram mechanism, and another supports
Bar 14 is hinged with a side link 8 in back mechanism.Jointed shaft between support bar 13 and side link 4, with
Jointed shaft between side link 4 and left side bearing frame 1 is same jointed shaft 15.Hinged between support bar 14 and side link 8
Axle, is same jointed shaft 16 with the jointed shaft between side link 8 and right side bearing frame 2.As in figure 2 it is shown, at two support bars
13, under the constraint of 14, the slide block 12 position on public connecting rod 11 changes along with the deformation of two parallel-crank mechanisms.
Referring also to Fig. 1, Fig. 3, is fixed with a hook 17 on public connecting rod 11, and this hook 17 is a pin,
Slide block 12 is provided with a movable hook 18.When two parallel-crank mechanisms are deformed between arranged on left and right sides bearing frame 1,2
Distance when pulling open to maximum, that is under state shown in Fig. 1, the hook on slide block 12 can hook public connecting rod as shown in Figure 3
Hook 17 on 11, can not slide on public connecting rod 11 so that slide block 12 is locked in.Slide block 12 is locked at public connecting rod 11
After Ding, as it is shown in figure 1, define the rock-steady structure of similar triangle between arranged on left and right sides bearing frame 1,2 so that open shape
Shelf under state are the most firm.
As preferred forms, seeing Fig. 3 and combine Fig. 4, the hook 18 on slide block 12 is a crotch, hook 18 with
One handle 19 is hinged, and can rotate around the jointed shaft 20 of this hinge point；Handle 19 is hinged with slide block 12, and can be hinged around this
The jointed shaft 21 at position rotates.The rotational plane of hook 18 and the rotational plane of handle 19 are each parallel to parallel-crank mechanism
Deformation Activities plane, that is be parallel to the plane at drawing place in the drawings.Along with the rotation of handle 19, hook 18 both can be such as figure
3 fasten with the hook 17 on public connecting rod 11 like that, can separate with the hook 17 on public connecting rod 11 as shown in Figure 4 again.This reality
Execute the hook 18 that example both can guarantee that on slide block 12 can firmly fasten with the hook 17 on public connecting rod 11, be avoided that again slide block
Hook 18 on 12 and the range of activity of handle 19 occupy the material-putting space of shelf.
When needs folding goods shelf when, the most as shown in Figure 4, turning handle 19, make the hook 18 on slide block 12 with public
Hook 17 on connecting rod 11 separates, and makes the slide block 12 can on public connecting rod 11 slidably, more as shown in Figure 2, by arranged on left and right sides
Bearing frame 1,2 closes up to centre, until as shown in Figure 5, both sides bearing frame 1,2-in-1 hold together to hithermost degree, the most just complete
The folding operation of shelf.
Embodiment two
Seeing Fig. 6, the present embodiment the difference is that only with embodiment one, two support bars that slide block 12 is hinged
13,14, hinged with the frame of parallel-crank mechanism respectively, that is the support bar 13 on the left side is hinged with left side bearing frame 1, the right
Support bar 14 hinged with right side bearing frame 2.Other structures of the present embodiment are identical with embodiment one, repeat no more.
Embodiment three
Seeing Fig. 7, the present embodiment, on the basis of embodiment one, adds a rack being positioned at shelf top
22, this top layer rack 22 is connected between arranged on left and right sides bearing frame 1,2, and hinged with one of them bearing frame 1.Folding
During folded shelf, first top layer rack 22 is overturn position shown in the imaginary line to Fig. 7, make top layer rack 22 and bearing frame 1
Side by side, the most again arranged on left and right sides bearing frame 1,2 is closed up to centre as shown in Figure 2, i.e. complete the folding of shelf.The present embodiment
Both add the storage space of shelf, maintain again the advantage that shelf are prone to fold.
Structure described in embodiment two is equally applicable to the present embodiment.
Embodiment four
Seeing Fig. 8, the present embodiment, on the basis of embodiment one, adds a bearing frame 23 erect more.Every two
Between individual adjacent bearing frame, be provided with the structures such as parallel-crank mechanism, slide block, hook, and these structures with shown in Fig. 1
Embodiment is identical, repeats no more.Fig. 9 shows the deformation process of the present embodiment.The present embodiment can also as shown in Figure 7,
One top layer rack is set between the bearing frame that each two is adjacent, two top layer racks respectively with outermost bearing frame
1,23 is hinged.
Embodiment five
As the distressed structure of a kind of simplification of previous embodiment, in two support bars that described slide block can be coupled
One omitted.Such as, a support bar 14 in Fig. 1 is omitted.Although so the most attractive in appearance in moulding, and firmly
Property also decreases, but still has the robust structure of similar triangle.The structure of this simplification also belongs to this utility model
Protection domain.
