Description

Technical Field

[0001] This utility model relates to the field of storage box technology, specifically a plastic storage box. Background Technology

[0002] Plastic storage boxes emerged with the development of the plastics industry. Plastics possess numerous advantages, including being lightweight, corrosion-resistant, and waterproof. For example, common polypropylene (PP) plastic has a low density, making storage boxes lightweight and easy to move. Furthermore, PP plastic has good chemical stability, exhibiting strong resistance to most acids and alkalis, and will not rust or corrode like metal under normal use conditions.

[0003] Plastic storage boxes are usually equipped with lids. In the existing technology, the lids of traditional storage boxes are mostly separate. When opened, the lids separate from the box body, making it difficult to place the lids, which is very inconvenient. Therefore, this utility model proposes a plastic storage box to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, a sliding cover design is adopted, which ensures that the cover and the box are integrated into one piece, avoiding the problem of where to place the cover when opening the box. By setting up a synchronization mechanism, the covers on both sides can be opened simultaneously when opening the box, which facilitates operation and makes the center of gravity more stable when the cover opens to the sides.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing, with two symmetrically arranged covers slidably connected to the upper end of the housing. Fixing plates are fixedly connected to the front and rear side walls of the housing, and through slots are formed on both fixing plates. Two symmetrically arranged sliders are fixedly connected to the lower ends of the two covers, and the two sliders are slidably connected within the two through slots on both sides. A limiting mechanism for limiting the position of the covers is provided within each of the two through slots. A synchronizing mechanism for synchronizing the two covers is provided on the rear wall of the housing. The limiting mechanism includes a limiting rod fixedly connected between the inner walls at both ends of the through slot, and the limiting rod passes through and slidably connects to the two sliders.

[0008] Preferably, the synchronization mechanism includes two racks that are fixedly connected to the sidewalls of two sliders on the same side, and a rotating rod is rotatably connected to the sidewall of the housing, with a gear fixedly sleeved on the rotating rod.

[0009] Preferably, the two racks are respectively disposed on the upper and lower sides of the gear, and both racks mesh with the gear.

[0010] Preferably, the upper end of the box has an opening, and a partition is fixedly connected to the inner wall of the box.

[0011] Preferably, a first magnet is fixedly connected to the rear wall of one of the covers, and a second magnet that cooperates with the first magnet is fixedly connected to the side wall of the box.

[0012] Preferably, the lower end of the housing is provided with four rollers, which are arranged in a rectangular pattern.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a plastic storage box with the following advantages:

[0015] 1. By setting up a cover and a limiting mechanism, when the covers on both sides are closed, the first magnet and the second magnet are joined together. When the box is opened, pulling one side of the cover separates the first magnet and the second magnet. The slider at the bottom of the cover can slide in the through groove and tend to be stable under the action of the limiting rod. The sliding cover design can ensure that the cover and the box are integrated, avoiding the problem of where to put the cover when opening the box and improving the convenience of the device.

[0016] 2. By setting a synchronization mechanism, when opening the cover, pulling one side of the cover moves the slider, which in turn moves the rack on one side. The movement of the rack drives the gear to rotate, and the rotation of the gear drives the rack on the other side that meshes with the gear to move. The two racks move in opposite directions, which can open the covers on both sides at the same time. This makes operation easier, and the cover opens to both sides, making the center of gravity more stable after opening. Attached Figure Description

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1-5 A plastic storage box includes a box body 1. The upper end of the box body 1 is slidably connected to two symmetrically arranged covers 2. Fixing plates 5 are fixedly connected to the front and rear side walls of the box body 1. Each of the two fixing plates 5 has a through groove 6. The lower ends of the two covers 2 are fixedly connected to two symmetrically arranged sliders 7. The two sliders 7 are slidably connected in the two through grooves 6 on both sides.

[0027] Furthermore, each of the two through slots 6 is provided with a limiting mechanism for limiting the cover 2. The limiting mechanism includes a limiting rod 11 fixedly connected between the inner walls of both ends of the through slot 6. The limiting rod 11 passes through the two sliders 7 and is slidably connected to them. The limiting rod 11 is set horizontally, which can limit the cover 2 and improve the stability of the movement of the cover 2.

[0028] Furthermore, a synchronization mechanism for synchronizing the two covers 2 is provided on the rear wall of the housing 1. The synchronization mechanism includes two racks 12 that are fixedly connected to the opposite side wall of the two sliders 7 on the same side. A rotating rod is rotatably connected to the side wall of the housing 1. A gear 13 is fixedly sleeved on the rotating rod 12. The two racks 12 are respectively located on the upper and lower sides of the gear 13, and both racks 12 mesh with the gear 13.

[0029] Furthermore, an opening 3 is provided at the upper end of the box 1, and a partition 4 is fixedly connected to the inner wall of the box 1. The partition 4 can divide the inside of the box 1 into sections, making it convenient to store different items.

[0030] Furthermore, a first magnet 9 is fixedly connected to the rear wall of one of the covers 2, and a second magnet 10 that cooperates with the first magnet 9 is fixedly connected to the side wall of the box 1. The first magnet 9 and the second magnet 10 attract each other, and when the covers 2 are closed, the first magnet 9 and the second magnet 10 are magnetically attracted together.

[0031] Furthermore, the lower end of the box 1 is provided with four rollers 8, which are arranged in a rectangular shape. The rollers 8 allow the box 1 to be moved conveniently.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] When the two covers 2 are closed, the first magnet 9 and the second magnet 10 close together. When the box 1 is opened, pull one cover 2 to separate the first magnet 9 and the second magnet 10. The slider 7 at the lower end of the cover 2 can slide in the through groove 6 and tend to be stable under the action of the limit rod 11. The sliding cover design ensures that the cover 2 and the box 1 are integrated, avoiding the problem of where to put the cover 2 when opening the box, thus improving the convenience of the device. When one cover 2 is opened, it drives the slider 7 on one side to move, thereby driving the rack 12 on one side to move. The movement of the rack 12 can drive the gear 13 to rotate. The rotation of the gear 13 can drive the rack 12 on the other side that meshes with the gear 13 to move. The two racks 12 move in opposite directions, which can realize the simultaneous opening of the two covers 2. While facilitating operation, the cover 2 opens to both sides, making the center of gravity of the device more stable after opening.
