Background technology
Rack generally is used for household to be used or merchandise display, how to be made up of shaped as frame support body and corresponding glove grillage, how fixing by welding between support body and the glove plate, can't split, can't fold, small product size is big, transportation is inconvenient, takes in and takies the increasing storage area.
Patent document CN202567011U discloses a kind of folding rack, comprise that a main frame reaches one deck laying rack at least, described main frame comprises left and right sides vertical rod and the horizontal support member of fixedlying connected with left and right sides vertical rod, described laying rack laterally is movably hinged between the vertical rod of the left and right sides, described horizontal supports is located at described laying rack front lower place, and described laying rack is positioned to level by described horizontal supports supporting when open mode.The folding rack of this patent disclosure, though can fold, complex structure, means such as needs welding realize the connection of parts, cost is higher.
The utility model content
The utility model provides a kind of bilateral folding rack at above shortcoming, to reach simple in structure, the folding purpose flexibly of opening.
For achieving the above object, the utility model takes following technical proposals to realize:
A kind of bilateral folding rack, two supports, at least one pair of laminate about comprising, at least one crosspiece, described a pair of laminate is positioned on the same horizontal plane, two relative side both sides of laminate are movably connected on respectively on the support of the left and right sides, crosspiece is positioned at whenever layer by layer on the plate, is fixedly connected on the support of the left and right sides.
Further, described support side is isosceles trapezoid, and bottom width is greater than top width.
Further, the middle groove that is provided with under shed of support side bottom.
Further, described laminate is movably connected on the support of the left and right sides by screw.
Further, described crosspiece is fixedly connected on the support of the left and right sides by screw.
Further, the laminate bottom surface of the bottom is provided with base.
Preferably, described rack is provided with five plates layer by layer.
Preferably, described rack is provided with four crosspieces.
Further, described laminate is rectangular frame, is provided with many wide grooves in the framework.
In a word, the beneficial effects of the utility model are: this bilateral folding commodity shelf structure is simple, can open to both sides flexibly, and both sides are inwardly folding simultaneously when folding, and when not using, folding taking in can take full advantage of the space, convenient transportation and storage.
Further, the support side is isosceles trapezoid, and bottom width is greater than top width, and the support of this shape is low wide and up narrow, and it is safe to lay, and guarantees that the stable of whole rack stand.
Further, be provided with the groove under shed in the middle of the support side bottom, handsome in appearance, be convenient to carrying.
Further, laminate is movably connected on the support of the left and right sides by screw, connects simply, saves cost.
Further, described crosspiece is fixedly connected on the support of the left and right sides by screw, and crosspiece plays the function of the displacement of restriction laminate when opening on the one hand, makes maintenance level in position when laminate is opened, also play the position-limiting action of placing article on the other hand, prevent that article from dropping from rear side.
Further, the laminate bottom surface of the bottom is provided with base, and when opening, base can help bottom laminate maintenance level, is convenient to be placed on the ground.
Further, rack is provided with five plates layer by layer, according to actual needs, take into account the stable of whole rack, the number of plies of laminate can be set arbitrarily, the number of crosspiece can be consistent with the number of laminate, in particular cases, because the laminate of the bottom is provided with base, has played spacing effect, the crosspiece of the laminate top of the bottom can omit.
Further, described laminate is rectangular frame, is provided with many wide grooves in the framework, but this kind design one side economical with materials is saved cost, and is visually attractive in appearance on the other hand.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the structural representation when bilateral folding rack is opened among better embodiment of the utility model, Fig. 2 is the structural representation of aforementioned bilateral folding rack when folding, in conjunction with Fig. 1 and Fig. 2 as can be known, this bilateral folding rack, two supports 1,2, four crosspieces 3 of five pairs of laminates about comprising.
Wherein the side of left and right sides support 1 is isosceles trapezoid, and bottom width is greater than top width, and this structure makes being positioned on the ground that rack can be stable.
In the present embodiment, laminate 2 is rectangular frame, is provided with many wide grooves in the framework, but this kind design one side economical with materials is saved cost, and is visually attractive in appearance on the other hand.
Each is positioned on the same horizontal plane laminate 2, forms one deck laminate 2, and every plate 2 relative side both sides layer by layer are movably connected on respectively on the left and right sides support 1.In the utility model, described laminate 2 can adopt multiple movable connection method such as hinged to be connected in left and right sides support 1, and is preferred, and in the present embodiment, laminate 2 adopts screws to be movably connected on the left and right sides support 1.
Crosspiece 3 is positioned on the laminate 2, be fixedly connected on the left and right sides support 1, the function of the displacement that described crosspiece 3 plays restriction laminate 2 on the one hand when opening makes maintenance level in position when laminate 2 is opened, also play the position-limiting action of placing article on the other hand, prevent that article from dropping from rear side.
In the utility model, described crosspiece 3 can be fixed on the left and right sides support 1 in several ways, and preferred, crosspiece 3 is fixedly connected on the left and right sides support 1 by screw.
In the utility model, described crosspiece 3 can be identical with the number of laminate 2, also can save the crosspiece 3 on bottom laminate 2 tops, save material, reason is that bottom laminate 2 bottom surfaces are provided with base 4, can be when opening, base 4 can help bottom laminate 2 maintenance levels, can save crosspiece 3 herein thereby play position-limiting action.Base 4 plays fixation simultaneously, is convenient to rack and is placed on the ground.
Though the utility model discloses as above with preferred embodiment, the utility model is not to be defined in this.Any those skilled in the art in not breaking away from spirit and scope of the present utility model, all can do various changes and modification, and therefore protection domain of the present utility model should be as the criterion with claim institute restricted portion.
