Description

The utility model relates to a foldable storage box used for transporting automatic two-wheel vehicles and car parts, in particular to a hinge device for freely rotating connection of plates.

In order to facilitate the transportation of boxes or the storage of articles, such as cartons, the general practice in the prior art is to fold the quadrangular boxes to make the volume smaller. However, when the side panels of the box are made of rigid materials such as steel plates or synthetic resin panels, it is difficult to fold them. Therefore, usually, the pillars or support frames are made separately from the side panels, and the side panels are separated. Bolted to a post or support frame.

However, using the above method, the pillars and the support frame must be prepared separately, and the pillars and the support frame should be combined. Secondly, the side plates should be connected by means of bolts, etc. The operation process takes a lot of time. or damaged, it cannot be used again.

Therefore, in order to overcome the above shortcomings, the rigidity of the above-mentioned side panels is strengthened, and the pillars or support frames are omitted or simplified, and the side panels are connected by hinges so that they can be folded. The structure of a general hinge is composed of two pairs of connecting plates and the shafts connecting these hinges. The structure is complicated, the cost is high, and the connecting plates need to be combined with the side plates, which increases the working time. And when wanting to make this folding structure open into a box, if the relative angle between each plate cannot be maintained correctly, the box then cannot become a square but becomes a parallelogram or a rhombus.

When folding the box, or restoring the box lightly, a spring should be installed between the plates so that the box can be deformed when folded and restored by the elastic force generated by the spring. However, in this case, it is difficult to make the board smaller or thinner due to the hindrance of the above-mentioned spring member.

The purpose of this utility model is to overcome the shortcomings of the above-mentioned prior art and provide a folding box with a hinge device. The folding box is composed of several metal plates connected by hinges so that it can rotate freely. It is constituted as a box that can be folded and combined freely.

The purpose of this utility model is achieved by providing a folding box with a hinge device, including several metal plates, the above plates are connected to each other by hinges, and the ends of these side plates are connected to each other. Reinforcing parts are provided on the end faces that can be touched, and spring parts are arranged between the side plates on both sides. The spring parts are arranged on the end faces of the strengthening parts of the adjacent side plates, so that the side plates can be pressed against each other by their torsion. Have an effect.

The utility model provides a folding box with a hinge device, which is provided with reinforcing parts along the periphery of the side plates to be connected with each other, and at the same time forms a cylindrical bearing that can roll back a part of the periphery, and inserts a hinge inside the bearing Shaft, at the same time the end of the hinge shaft is bent with one end to the left and the other end to the right, and the torsion force generated by the bent end makes the side plate have a tendency to lean aside.

Since the box connects several side panels with the hinge device, the side panels form a state that cannot be separated from each other. The box has acquired the required rigidity due to the side panels themselves being reinforced by the reinforcement members at the periphery. When the reinforcing part combines the side plates at the predetermined combined position, the spring member presses the opposite surfaces into a contact state, thereby enabling the angle of the side plates to be restored correctly, so the combined box can maintain its proper shape. In addition, the above-mentioned spring parts are installed between the adjacent side plates, and although the folding of the box is carried out by resisting the elasticity of the spring parts, when the side plates are folded and assembled again, when folding, due to the release of the spring parts Energy, and the force required for restoration is relatively small, so it can be restored.

The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings. In the attached picture,

Please refer to Fig. 1, 10 is the folding box of the present utility model that has hinge device 30. The folding box 10 is composed of three fixed side plates 12 (12a, 12b, 12c) and an opening and closing side plate 13, which are also made of steel plates, on a steel plate chassis 11. That is to say, the opening and closing side plate 13 can be opened and closed freely, and is supported by the straight direction hinge 31 of the hinge device 30 that is arranged on the fixed side plate 12c, and is provided with through hole on one side, can be located at The fixing member 15 on the fixing side plate 12a on the other side is inserted and fixed.

The chassis 11 is slightly larger than the side plates 12 and 13, and its planar shape is slightly square. The bottom of the chassis 11 is supported by two pillows 16 on the left and right, and the fork bar (not shown in the figure) of the stacker can be inserted between these pillows 16 .

The above-mentioned three fixed side panels 12 and one opening and closing side panel 13 forming the folding box 10 are configured to be able to be folded freely on the chassis 11 . That is to say, the chassis 11 is connected to the connecting edge 17 with the fixed side plate 12a rotatably, and the fixed side plate 12a is connected to the connecting edge 18 with the fixed side plate 12b rotatably, and the fixed side plate 12b is connected with the other A fixed side plate 12c is rotatably connected to the connecting edge 19 . Each of the fixed side plates 12 and the like are two boards in the shape of an equilateral triangle, and these inclined sides are connected by an inclination direction hinge 32 of a hinge device 30 described below to form a substantially square shape.

As shown in Figure 2, the hinge device 30 is provided with several protrusions at the end of the side plate, and the protrusions are rolled back into a cylindrical shape as a bearing 35, and the side plate bearings 35 to be connected are formed into a concave-convex shape. After fitting them to each other, the hinge shaft 33 is inserted into the above-mentioned bearing 35, and the side plates connected to each other are configured to be in a rotatable state. Here, the spring member 40 bends the two ends of the above-mentioned hinge shaft 33 with one end to the left and the other end to the right. Since the bent ends 34 have different directions, the plate has a tendency to lean aside. The above-mentioned hinge shaft Acts as a torsion spring. 41 covers the above-mentioned curved end 34, and is a cap made of rubber-like elastic body to protect the surface of the board from damage.

On these plate materials forming equilateral triangles and on the periphery of the above-mentioned opening and closing side plates 13, a reinforcing member 21 with a cross-sectional shape that is a square tube is welded, and a spring member 40 is provided at the part that becomes the connecting edge 17, and these sides are connected to each other. The board and the like are attached to the direction of leaving aside.

As in the embodiment constituted above, if the folding box 10 is to be folded, each plate should be folded at the connecting edge as shown by the solid line in FIG. 3 , and the hinge shaft 33 is twisted by the plate. Therefore, when the folding force is released, the two panels have a tendency to elongate by virtue of the torsional energy stored in the hinge device 33 . As shown by the dotted line in Fig. 3, due to the elongation of the hinge shaft 33, the end faces of the reinforcement members 21 welded to each plate can contact each other on both sides of the hinge device 30, so each plate forms a plane.

The plate in this embodiment is a steel plate, and the reinforcing parts are fixed by welding, but the content of the utility model is not limited thereto, and other materials such as metal plates or hard synthetic resins are also included.

As mentioned above, in the utility model, several side panels made of metal plates are combined by hinge shafts to form a box. Therefore, when the box is folded, not only will the parts not be separated, but they will not be lost.

The hinge device connecting each side plate uses the two ends of the hinge shaft as springs with torsion force bent left and right, and forms a spring part to function. Therefore, compared with manufacturing the spring part and the hinge device separately, not only the structure is simple, At the same time, the spring member can also be arranged at the end of the side plate, or at the narrow part between the side plates, and the enlargement of the hinge device can be avoided.

When the folded box is reassembled, the torsion force of the spring will help the plate to stand upright, so the workload can be reduced, and the assembly of relatively large boxes can be easily carried out.

In addition, the peripheral part of the board is provided with a reinforcing part. Since the end face of the reinforcing part has set the stretching angle of the board, when the folded board is to be restored into a box, it can still be restored according to the set size and shape of the box.
