[0002] A storage box is a container for storing items. Existing storage boxes generally include a box body and a door arranged on the front side of the box body. Among them, the opening methods of the door mainly include single-opening and double-opening.

[0003] For example, a plastic product placement box (application number: 201721600927.4) disclosed in Chinese patent literature includes a box body shell and a movable door. The left end of the movable door is movably connected to the left end of the box body shell. A hinge is fixedly installed at the front end of the left side of the box body shell, and the left end of the movable door is movably connected to the front end of the left side of the box body shell through the hinge. A clamping groove is arranged at the front end of the right side of the box body shell, and a clamping pin matched with the clamping groove is fixedly connected to the edge of the inner surface of the movable door. This placement box adopts a single-opening structure. Although the opening process of its movable door is relatively convenient, when the movable door of the placement box is opened, sufficient space needs to be left on the front side of the placement box. In this way, when the placement box is used in a narrow space, the opening and closing of the movable door are inconvenient. Summary of the Invention

[0004] The purpose of the utility model is to address the above problems existing in the prior art and propose a door structure of a storage box. On the basis of ensuring the reliability of the use of the door structure, the utility model solves the problem that the opening and closing of the door of the existing storage box are inconvenient when used in a narrow space.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A door structure of a storage box, the storage box includes a box body with an open front side, the box body includes a bottom plate and a panel arranged parallel above the bottom plate. The door structure includes two symmetrically arranged door bodies on the left and right. It is characterized in that an upper guide groove is arranged along the left side, front side and right side of the panel at the bottom edge of the panel, and a lower guide groove is arranged along the left side, front side and right side of the bottom plate at the top edge of the bottom plate. The top edge of the door body is slidably embedded in the upper guide groove and the bottom edge is slidably embedded in the lower guide groove. The door body is sequentially spliced by a plurality of vertically arranged grid door strips. Adjacent two grid door strips are connected into one body through a deformable connecting part, and an avoidance gap is formed between adjacent two grid door strips.

[0006] An upper guide groove is arranged at the bottom surface of the panel, and a lower guide groove is arranged at the top surface of the bottom plate. The top edge and the bottom edge of the door body are respectively slidably embedded in the upper guide groove and the lower guide groove. In this way, not only the installation of the door body is realized, but also the door body can slide along the upper guide groove and the lower guide groove.

[0007] When both door bodies slide to the front side of the box body, the two door bodies block the opening of the box body, thus closing the door of the storage box. When the door of the storage box needs to be opened, only need to slide the two door bodies to both sides respectively. At this time, since the adjacent two grille door strips are connected into one body through the deformable connecting part, and there is an avoidance gap between the adjacent two grille door strips, so during the movement of the door body, when the door body moves to the turning point, the connection part between the adjacent two grille door strips will deform, and the existence of the avoidance gap enables the adjacent two grille door strips to approach each other when the connection part deforms, so that the door body can be bent along the extension direction of the upper guide groove and the lower guide groove. Finally, the door body on the left can slide from the front side edge of the bottom plate and the panel to the left side edge of the bottom plate and the panel, and the door body on the right can slide from the front side edge of the bottom plate and the panel to the right side edge of the bottom plate and the panel. At this time, the two door bodies are respectively on the left and right sides of the storage box, thus opening the door of the storage box.

[0008] Obviously, when this storage box is in use, the two door bodies only need to slide along the edges of the bottom plate and the panel to open or close the door of the storage box. During this process, the door bodies will not occupy the space beside the storage box, so it can be carried out in a narrow space, making the storage box more convenient to use. And because the door body of the structure of this box door is formed by splicing a number of vertically arranged grille door strips in sequence, only the connecting part deforms during the movement of the door body, and the grille door strips do not need to deform, so they can maintain good structural strength, and then enable the door body to have better anti-impact ability, so as to ensure that the door body still has good use reliability and service life when it can be bent along the extension direction of the upper guide groove and the lower guide groove.

[0009] In the door structure of the above storage box, the grille door strip includes a strip-shaped plate-like base plate. The base plates of the adjacent two grille door strips are connected into one body through the above-mentioned connecting part. There is a rectangular border arranged around the edge of the base plate on the inner side surface of the base plate, and a concave cavity is formed inside the rectangular border. Setting a rectangular border on the inner side surface of the base plate can improve the structural strength of the grille door strip, avoid the grille door strip from bending and deforming itself, make the door body have good structural strength and anti-impact ability, and improve the use reliability of the door body. At the same time, the concave cavity inside the rectangular border can achieve the purpose of saving materials, thus reducing the manufacturing cost.

[0010] In the door structure of the above storage box, there is also a strip-shaped convex part on the outer side surface of the base plate, and the length directions of the convex part and the base plate are the same. Setting a convex part on the outer side surface of the base plate can further improve the structural strength of the grille door strip, avoid the grille door strip from bending and deforming itself. At the same time, with the convex part on the outside and the rectangular border on the inside, it can also make the door body more beautiful.

[0011] In the door structure of the above-mentioned storage box, a strip-shaped groove is provided on the side of the convex portion facing away from the substrate, and the length directions of the strip-shaped groove and the convex portion are the same. The provision of the strip-shaped groove can achieve the purpose of saving materials, thereby reducing the manufacturing cost.

[0012] In the door structure of the above-mentioned storage box, a strip-shaped protrusion is provided on the bottom of the lower guide groove along the extension direction of the lower guide groove, and the lower side of the bottom edge of the door body abuts against the strip-shaped protrusion. By providing the strip-shaped protrusion on the bottom of the lower guide groove, the bottom edge of the door body is slidably fitted in the lower guide groove and the lower side of the bottom edge of the door body abuts against the strip-shaped protrusion. In this way, the strip-shaped protrusion is used to support the door body, which can reduce the frictional resistance during the sliding process of the door body and make the sliding process of the door body smoother.

[0013] In the door structure of the above-mentioned storage box, the surface of the strip-shaped protrusion is an arc surface. This structure can not only enable the strip-shaped protrusion to support the door body well, but also reduce the contact area between the strip-shaped protrusion and the door body, thereby reducing the sliding resistance of the door body and making the door body slide more smoothly.

[0014] In the door structure of the above-mentioned storage box, the rightmost grille door strip on the left door body is the first left grille door strip, and the first left grille door strip has a right end face. The leftmost grille door strip on the right door body is the first right grille door strip, and the first right grille door strip has a left end face. When both door bodies slide to the front side of the box body, the right end face can be abutted against the left end face. The right end face of the first left grille door strip can be abutted against the left end face of the first right grille door strip, ensuring that the storage box has good airtight performance when the door of the storage box is closed.

[0015] In the door structure of the above-mentioned storage box, a positioning protrusion is provided on the right end face of the first left grille door strip, and a positioning groove that can be inserted and matched with the positioning protrusion on the right end face is provided on the left end face of the first right grille door strip; or a positioning groove is provided on the right end face of the first left grille door strip, and a positioning protrusion that is inserted and matched with the positioning groove on the right end face is provided on the left end face of the first right grille door strip; or a positioning protrusion and a positioning groove are provided on the right end face of the first left grille door strip, and a positioning groove that is inserted and matched with the positioning protrusion on the right end face and a positioning protrusion that is inserted and matched with the positioning groove are provided on the left end face of the first right grille door strip. When both door bodies slide to the front side of the box body, the right end face and the left end face of the two door bodies are abutted against each other. At this time, through the insertion and matching of the positioning protrusions and positioning grooves on the left end face and the right end face, the two door bodies are locked to each other and will not open by themselves, thereby further improving the convenience during the use of the storage box.

[0016] In the door structure of the above-mentioned storage box, the box body further includes a left side plate and a right side plate. The upper guide groove and the lower guide groove both include a left guide section, a front guide section, and a right guide section that are sequentially connected. The left guide sections of both the upper guide groove and the lower guide groove are located outside the left side plate, and the right guide sections of both the upper guide groove and the lower guide groove are located outside the right side plate. This design ensures that the left door does not interfere with the left side plate during the opening process, allowing the left door to finally slide outside the left side plate. Similarly, the right door does not interfere with the right side plate during the opening process, enabling the right door to finally slide outside the right side plate. Additionally, this structure positions the door outside the left side plate or the right side plate, so that when the door is opened or closed, it can be slid by pulling, making the opening and closing of the door smoother and more convenient.

[0017] In the door structure of the above-mentioned storage box, both ends of the front guide section are connected to the left guide section and the right guide section through arc-shaped sections. By setting the arc-shaped sections, it can ensure that the left door slides smoothly back and forth between the front guide section and the left guide section, and at the same time ensure that the right door slides smoothly back and forth between the front guide section and the right guide section, making the process of opening and closing the door smoother and enhancing the convenience during the use of the storage box.

[0018] In the door structure of the above-mentioned storage box, handles are provided on the outer side surfaces of the first left grille door strip and the first right grille door strip. The provision of the handles facilitates pulling the door to slide, enhancing the convenience of use.

[0019] Compared with the prior art, the door structure of this storage box has the following advantages:

[0020] 1. When this storage box is in use, the two doors only need to slide along the edges of the bottom plate and the panel to open or close the door of the storage box. During this process, the doors do not occupy the space beside the storage box, so it can be carried out in a narrow space, making the use of the storage box more convenient.

[0021] 2. By providing a strip-shaped protrusion on the bottom of the lower guide groove, the bottom edge of the door slides and is embedded in the lower guide groove, and the lower side surface of the bottom edge of the door abuts against the strip-shaped protrusion. In this way, the strip-shaped protrusion is used to support the door, which can reduce the frictional resistance during the sliding process of the door, making the sliding process of the door smoother. When the box door is closed, the two opposite end faces of the two doors are positioned through the plug-in structure, so that the two doors are locked to each other and will not open by themselves when the box door is closed, thereby further enhancing the convenience during the use of the storage box.
