Description

Technical Field

[0001] The utility model relates to the technical field of storage boxes, in particular to a portable plastic storage box. Background Art

[0002] With the development of society and technology, there are more and more supplies in the car, and the demand for storage boxes is getting higher and higher. Cars are generally equipped with trunks, but with the changes in travel needs, in order to maximize the use of storage space in the car, more and more users place portable storage boxes in the car, which is convenient for organizing and placing items, and convenient for carrying in the car.

[0003] However, the existing plastic storage boxes are generally equipped with an upper cover, and half of the upper cover is clamped to the storage box by a fixed buckle structure. This method is very laborious and inconvenient to open and close the box cover when in use, and is not easy to operate. In addition, when the storage boxes are stored idle, they are generally nested with each other to save space. However, after the inner storage box is inserted into the lower storage box, due to the smooth inner surface and close contact with each other, when it is used again, negative pressure is formed inside due to the close contact, which makes it difficult to separate and inconvenient to use.

Two limit blocks are installed on the front and back sides of the box body. A top cover mechanism is clamped inside the box body, and the tops of the front and back sides of the top cover mechanism are in contact and cooperate with the two limit blocks.

[0007] As a further description of the above technical solution: the top cover mechanism includes two cover plates and three tension springs, the opposite sides of the two cover plates are hinged to each other, the opposite sides of the two cover plates are respectively engaged with the limit blocks on both sides, the two ends of the tension spring are respectively fixedly connected to the opposite sides of the two cover plates, and the tension spring is centered on the hinge axis of the opposite side of the two cover plates.

[0008] As a further description of the above technical solution: a storage groove is provided on each of the two cover plates, and a handle is hinged inside the storage groove.

[0009] As a further description of the above technical solution: handles are fixedly connected to the front and rear sides of the box body.

[0010] As a further description of the above technical solution: both the front and rear sides of the box body are fixedly connected with X-shaped reinforcing ribs.

[0011] As a further description of the above technical solution: grounding bumps are arranged at the four corners of the bottom of the box body.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] This solution uses the vertical slot in conjunction with the top cover mechanism, so that the device has the advantages of being more labor-saving and convenient to operate the box cover opening and closing, and when the storage boxes are stacked and stored, the airflow flows smoothly when taking and placing, and the storage and separation are convenient.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 4 In the utility model, a convenient plastic storage box includes a box body 1, which is a rectangular body that is wide at the top and narrow at the bottom. Two vertical grooves 2 are provided at the corners of the outer side of the box body 1. The top and bottom ends of the vertical grooves 2 extend to the top and bottom of the box body 1 respectively. Two limit blocks 3 are installed on the front and back sides of the box body 1. A top cover mechanism 5 is clamped inside the box body 1, and the tops of the front and back sides of the top cover mechanism 5 are in contact with the two limit blocks 3.

[0022] In the utility model, the box body 1 is used as the main body of the device. First, the vertical grooves 2 at the four corners are used to make the two box bodies 1 engage with each other for storage. There is a gap between the two box bodies 1. When taking and placing, the air inside the space between the two box bodies 1 is discharged and entered smoothly, avoiding pressure difference, which is convenient for storage and use. The top cover mechanism 5 cooperates with the four limit blocks 3 to achieve compatibility with the box body 1. When opening, it is only necessary to pull the top cover mechanism 5 and fold it from the middle to take it out, which is labor-saving. Therefore, the device has the advantages of more labor-saving and convenient box cover opening and closing operation, and when the storage boxes are stacked for storage, the air flow is smooth when taking and placing, and it is convenient to store and separate. This solves the problem that the prior art generally realizes space-saving storage by mutually nesting, but after the internal storage box is inserted into the storage box below, due to the smooth internal surface and close contact with each other, when it is used again, negative pressure is formed inside due to the close contact, which makes it difficult to separate and inconvenient to use.

[0023] See also Figure 1 and Figure 3 , wherein: the top cover mechanism 5 includes two cover plates 51 and three tension springs 52, the opposite sides of the two cover plates 51 are hinged to each other, the opposite sides of the two cover plates 51 are respectively engaged with the limit blocks 3 on both sides, the two ends of the tension spring 52 are respectively fixedly connected to the opposite sides of the two cover plates 51, and the tension spring 52 is centrally distributed on the hinge axis of the opposite side of the two cover plates 51.

[0024] In the present invention, two cover plates 51 cooperate with three tension springs 52 , and under the tension of the three tension springs 52 , the two cover plates 51 are kept in a horizontal state, so as to achieve a stable connection with the box body 1 .

[0025] See also Figure 3 , wherein: a storage groove 511 is formed on each of the two cover plates 51 , and a handle 512 is hinged inside the storage groove 511 .

[0026] In the utility model, the middle parts of the two cover plates 51 are pulled upward by the handle 512 inside the storage groove 511, so that the three tension springs 52 are pulled up, and the other side of the cover plate 51 is blocked by the limit stopper 3, so that the opposite side of the two cover plates 51 is bent upward, so that the two cover plates 51 are relatively close to each other and separated from the limit stopper 3, and the opening is realized, and the operation is labor-saving and convenient.

[0027] See also Figure 1 and Figure 3 , wherein: handles 6 are fixedly connected to the front and rear sides of the box body 1.

[0028] In the utility model, the box body 1 is conveniently taken out through the handle 6 .

[0029] See also Figure 1 , wherein: the front and rear sides of the box body 1 are fixedly connected with X-shaped reinforcing ribs 7.

[0030] In the utility model, the structure of the box body 1 is reinforced by the X-shaped reinforcing ribs 7 to increase the structural strength.

[0031] See also Figure 1 , wherein: grounding bumps 4 are arranged at the four corners of the bottom of the box body 1 .

[0032] In the utility model, the grounding protrusion 4 makes the box body 1 more stably placed on the ground.

[0033] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
