Description

Foldable box with hinge

The utility model relates to the folding containing box that is used to carry automatic two-wheeled cycle and car part, particularly a kind of with between each sheet material to rotate bonded assembly hinge means freely.

For the conveying of chest or article storing convenient, carton and so on for example, the general way that adopts of prior art is folded tetragonal chest and is made smaller volume.But, when the side plate material of chest is steel plate or synthetic resin board etc. when having the high material of rigidity and making, it foldingly then be had any problem, therefore, usually with pillar or support frame and side plate to make respectively, and with side plate to be bolted on pillar or the support frame.

Yet, adopt said method pillar will be prepared respectively with supporting frame, and with pillar and the combination of support frame, secondly, side plate is connected in modes such as bolt, its operation process is time-consuming many again, and when taking apart,, then can't reuse if part is lost or infringement.

Therefore, for overcoming above shortcoming, in its rigidity of above-mentioned each side plate reinforcement itself, and pillar or support frame are omitted or simplification, and consider with the hinge connection it to be folded this side sheet room.The structure of general hinge, be by two pairs of connecting panels and is connected these hinges axle constituted, its complex structure, expense be high again, also need connecting panel is incorporated into side plate the increase production time.And when wanting that this folded structure is opened becomes chest, the relative angle between each sheet material is if can't correctly be kept, and chest then can't become square and become parallelogram or rhombus on the contrary.

When folding, when perhaps chest being recovered trippingly, should between each sheet material, install when spring installation makes chest folding and can be out of shape, and the elastic force that produces by spring recovered chest.Yet, little in this case because the obstruction of above-mentioned spring installation when wanting sheet material is done, perhaps do thin having any problem.

The purpose of this utility model is to overcome the shortcoming that above-mentioned prior art exists, a kind of folding carton that has hinge means is provided, and this folding carton is made up of several metal sheets, and is connected by hinge, it can be rotated freely, constitute the folding chest that can make up again freely of a kind of energy thus.

The purpose of this utility model reaches like this, a kind of folding carton that has hinge means promptly is provided, comprise several metal sheets, above-mentioned plate can be rotated mutually with hinge connected freely, and the end face that can touch mutually in the end of these side plates is provided with strengthening part, between the side plate of both sides, be provided with spring installation again and this spring installation is located at the end face of above-mentioned adjoining side plate strengthening part, make side plate borrow its torsion can be toward pushing direction generation effect mutually.

The folding carton that has hinge means provided by the utility model, be provided with strengthening part along the mutual bonded assembly side plate periphery of wanting, forming simultaneously can be with the cylindrical bearing of this periphery part rollback, and at the inner hinge axis that inserts of this bearing, simultaneously with this hinge axis end with an end left the other end make bending to the right, and the torsion that relies on this curved end to produce has toward the trend of bypassing the attached gesture of direction side plate.

Because chest is connected several side plates with hinge means, side plate then constitutes the state that can not break away from mutually.Because the cause that side plate itself is strengthened by the strengthening part of periphery, chest has obtained needed rigidity.Strengthening part with side plate be combined in during fixed block position, push by spring installation and to make its opposite face become state of contact, the angle of side plate is correctly recovered, so the chest that is made up can be kept due shape.In addition, above-mentioned spring installation is installed in institute in abutting connection with between the side plate, though and the folding of chest is to be undertaken by the elasticity of resisting spring installation, but when the folding state of side plate makes up once again, when folding, because spring installation releases energy, and it is also more small to recover required power, so can make its post-equalization.

Below with reference to accompanying drawing, most preferred embodiment of the present utility model is elaborated.In the accompanying drawing,

See also Fig. 1, the 10th, have the utility model folding carton of hinge means 30.Folding carton 10 is by being provided with three fixed side 12(12a that made by steel plate equally on

steel plate chassis

11,12b 12c) constitutes with side plate 13 with a switching.In other words, opening and closing side plate 13 can open and close freely, and supported to 31 on hinge by the Nogata that is arranged on the hinge means 30 on the fixed side 12c, be provided with open-work on it and at a side, can insert and be fixed by the fixed parts on the fixed side 12a that is located at another side 15.

Chassis 11 is big slightly than

side plate

12 and 13, and its aspect slightly is square.Below the chassis 11 by about two pillow materials 16 supported, between these pillow materials 16, can insert for the fork arm (not being shown among the figure) of Forklift.

Above-mentioned 3

fixed sides

12 and 1 that form folding carton 10 open and close side plate 13 and constitute and can fold freely on chassis 11.In other words, chassis 11 can be rotated fixed side 12a and be connected connection edge 17 freely, and fixed side 12a is with fixed side 12b, can rotate and be connected connection edge 18 freely, fixed side 12b can rotate and be connected connection edge 19 freely then with another fixed side 12c.Each fixed side 12 grade will be 2 sheet materials of two equilateral triangles respectively, at these inclined sides, be connected by the direction of tilt hinge 32 of following hinge means 30, and roughly form square.

Hinge means 30 as shown in Figure 2, be provided with several protuberances in side end, and with this protuberance rollback such as cylindrical shape as bearing 35, and mutually with want bonded assembly side plate bearing 35, form concavo-convex place with it mutually chimeric after, insert hinge axis 33 in above-mentioned bearing 35 inside, and interconnective side plate is constituted rotating state.At this, the other end is crooked to the right left with an end respectively with above-mentioned hinge axis 33 both ends for spring installation 40, because this curved end 34 has different directions, thereby sheet material is had toward the trend of bypassing the attached gesture of direction, and above-mentioned hinge axis plays torque spring.41 cover above-mentioned curved end 34, are the caps that is made by the rubber-like elastic body, injury-free with the protection plate surface.

Form the sheet material of two equilateral triangles and at the periphery of above-mentioned switching side plate 13, being welded with section form is the strengthening part 21 of quadrangular barrel at these, and, become and connect edge 17 parts and then be provided with spring installation 40, and with these side plates etc. toward bypassing the attached gesture of direction.

Embodiment as constituted above as folding carton 10 is folding, should press each sheet material among Fig. 3 and fold shown in the solid line connecting edge, and hinge axis 33 is the state that is reversed by sheet material.Therefore, when removing as if the power that will fold, two sheet materials have the trend of elongation by means of being stored in the amount of torsional energy of hinge means 33.Shown in the dotted line of Fig. 3, because the elongation of hinge axis 33, the end face that is welded on the strengthening part 21 of each sheet material can be in contact with one another, so each sheet material promptly forms the plane at the sheet material of hinge means 30 both sides.

The sheet material of present embodiment is steel plate, and strengthening part is fixing with welding, but the utility model content is not limited to this, and other is as metal sheet, in perhaps the materials such as synthetic resin of hard are also included within.

The utility model as previously discussed is combined in by hinge axis with several side plates that metal sheet was constituted and forms chest, and therefore, when chest was folding, each part did not only have phenomenon separately, can not lose yet.

The spring that each side plate bonded assembly hinge means is had these hinge axis two ends as bending right and left torsion, and form a spring installation and the generation effect, therefore, with spring installation and hinge means are made respectively compared with, simple structure not only, simultaneously also spring installation can be arranged on the end of side plate, or be located at the crevice between side plate and the side plate, and can avoid the maximization of hinge means.

During with folding chest recombinant, help sheet material is upright by the torsion of spring installation, therefore, can alleviate work capacity, also can carry out easily for case combination relatively.

In addition, the peripheral part of sheet material is provided with strengthening part, because the end face of this strengthening part with the stretching, extension angle initialization of sheet material, when the sheet material post-equalization that desire will fold is chest, still can recover according to the chest size and dimension that sets.
