Description

Technical Field

[0001] The utility model belongs to the technical field of plastic shells, and particularly relates to a plastic shell with good air permeability. Background Art

[0002] Plastic cases used to store items are usually container cases made of plastic materials. They come in a variety of shapes and sizes to suit the storage needs of different items. These plastic cases are generally lightweight and easy to carry and move. They have a certain degree of flexibility and impact resistance, and can protect the items stored inside from external collisions and extrusion to a certain extent.

[0003] Currently, storage boxes in the existing technology generally use plastic shells to store and protect items in the storage box. However, the internal space is fixed, and the internal space is often unevenly utilized due to the large and small items placed in it. Moreover, if the internal space is not full, once the storage box is moved, the items inside may move and become scattered. Therefore, we propose an environmentally friendly plastic shell made of PET modified plastic material;

[0004] Chinese patent publication number "CN214730757U" discloses an environmentally friendly plastic enclosure made of modified PET plastic material. The enclosure comprises a housing with a lid movably connected to the housing via a snap fastener. The housing is provided with an adjustment mechanism that can be freely adjusted to accommodate the size of the items placed therein and fully utilize the space within the housing. This environmentally friendly plastic enclosure made of modified PET plastic material, unlike existing technologies, can fully utilize the space within the storage box during use. By adjusting the position of the divider, items can be sorted and stored according to their size, preventing disorganization. Even when the storage box is not full, items will not be scattered due to the movement of the storage box. Furthermore, the operation is simple, fast, and very convenient.

[0005] Although the above-mentioned device can play a role in assisting the separation and storage during actual use, there are still obvious defects and shortcomings in the specific application process. First, during use, the overall storage state is sealed and the ventilation performance is poor. When storing items, some items usually need to be in a dry state. For example, when storing some Chinese herbal medicines, in order to maintain the quality and prevent them from getting damp and deteriorating, a well-ventilated environment is required; and when storing worn clothes, good ventilation is also required; in addition, items such as books and papers, if stored in a closed environment for a long time, are easily affected by moisture and deformed. However, the above-mentioned plastic shell cannot be conveniently and flexibly adjusted to be ventilated or sealed during the storage process. It can be seen that there are certain defects and shortcomings in its use, and it is in urgent need of improvement. Utility Model Content

[0009] The ventilation mechanism includes a ventilation slot and a storage frame. The ventilation slot is opened at the front ends of both sides of the shell, and the storage frame is fixedly installed at the rear ends of both sides of the shell. The interior of the shell is slidably connected with a sealing side plate, and the outer rear end of the sealing side plate is fixedly installed with a limiting component. The end of the limiting component passes through the sealing side plate, and the interior of the ventilation slot is fixedly installed with a dustproof screen.

[0010] As an optimal technical solution, the limit assembly includes a concave frame, the inner side of the concave frame is fixedly connected to a limit spring, the end of the limit spring is fixedly installed with a base plate, the side of the base plate close to the shell is fixedly installed with a limit pin, and the end of the limit pin passes through the sealing side plate and the outer side of the shell for fitting connection.

[0011] As a preferred technical solution, a pull-out frame is fixedly installed on the outer side of the base plate, and the overall cross-section of the pull-out frame is J-shaped.

[0012] As a preferred technical solution, a push plate is fixedly installed at the outer end of the pull-out frame, and the corners of the outer surface of the push plate are set to be arc-shaped.

[0013] As an optimal technical solution, the partition mechanism includes a slide groove, which is opened on one side of the upper end of the outer shell. Four groups of sliders are slidably connected inside the slide groove. A partition plate is fixedly installed on the side of the slider close to the inner shell, and a positioning component is fixedly connected to the upper end of the side of the partition plate close to the slider.

[0014] As an optimal technical solution, the positioning assembly includes a square groove, which is opened at the upper end of the partition plate close to the slider.

[0015] As a preferred technical solution, a connecting shaft is fixedly connected to a side of the limiting frame away from the limiting frame, and an end of the connecting shaft passes through the base plate and is fixedly connected to a pull ring.

[0016] In summary, the present invention has the following beneficial effects:

[0017] First, the device is equipped with a separation mechanism. When in use, the pull ring is pulled to move the limit frame, and the slider can be adjusted to slide in the slide groove to flexibly adjust the spacing between the partitions. After the spacing is adjusted, the pull ring is released, and the telescopic spring resets the limit frame to fix the slider and the partition. The spacing between the partitions can be quickly and flexibly adjusted to meet the storage needs of different items, improving the convenience of use.

[0018] Second, this device is equipped with a ventilation mechanism. When storing items that require sealing, push the push plate to disengage the pull-out frame and drive the limit pin to the side. Adjust the sealing side panel to cover the dust screen. Loosen the pull-out frame. The limit spring fixes the sealing side panel. When high ventilation is required, push the push plate to separate the limit pin from the outer shell and store the sealing side panel. The ventilation slots and dust screen assist in ventilation and dust prevention. BRIEF DESCRIPTION OF THE DRAWINGS
