Description

Technical Field

[0001] This utility model relates to the field of display box technology, and specifically to a portable display box. Background Technology

[0002] Display boxes are typically used to store and display items. They usually consist of a base and a display cover. When an item (such as an object made of building blocks) has a certain shape and an attractive appearance, it can be placed on the base of the display box and then covered with a display cover for display by others.

[0003] Existing display cases are generally simply nested into a base without any connection or fixation. Therefore, these display cases are inconvenient to carry. When carrying them, you need to hold the base with both hands; otherwise, if you hold the display case, the base may easily detach and fall due to the weight of the items. Of course, some display cases do have a connection and fixation structure, but these structures are either still inconvenient to carry after being fixed, or the process of fixing them is cumbersome.

[0004] For example, patent publication number CN220536245U discloses a modular building block display box. Magnetic sheets are embedded around the base, and metal sheets are embedded on the inside of the transparent display cover. The magnetic sheets and metal sheets are magnetically attracted to each other. When the transparent display cover is connected to the base, the metal sheets attract the magnetic sheets. When it's necessary to change the items inside the transparent display cover, the transparent display cover and base can be easily separated. The magnetic connection between the transparent display cover and the base improves the efficiency of changing items inside the building block display box. However, because the magnetic connection is not very secure, it is still inconvenient to directly carry or transport the protective cover.

[0005] For example, some display cases are connected to the base by screws. Although this connection is secure, it is inconvenient to remove the display case each time. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned problems and shortcomings by providing a portable display box, effectively solving the issues of current display boxes being inconvenient to carry and having unstable or cumbersome connections.

[0007] The technical solution of this utility model is implemented as follows: This utility model discloses a portable display box, comprising a display cover and a base, wherein the display cover and the base are fitted together to form the display box. The base has four side walls, a top surface facing the display cover, and a bottom surface opposite the top surface. A groove is formed by a gap between the edge of the top surface and the four side walls, and at least two side walls are recessed towards the edge of the top surface at their middle positions to form notches. A first connecting portion is provided at the notch. The opening edge of the display cover extends outwards at the position corresponding to the notch, and when the opening edge of the display cover is nested into the groove, the protruding edge is located at the notch. The box also includes locking components, the number of which is the same as the number of notches. Each locking component has a second connecting portion and a recess for the protruding edge to extend into. After the second connecting portion of the locking component connects with the first connecting portion, the protruding edge extends into the recess to lock the display cover and the base together.

[0008] In some embodiments, the connection direction of the second connecting portion relative to the first connecting portion is opposite to or perpendicular to the nesting direction of the display cover relative to the base.

[0009] In some embodiments, the first connecting part is a plug-in post, the length direction of which is consistent with the recessed direction of the notch; the second connecting part is a corresponding plug-in hole, the plug-in direction of which is perpendicular to the nesting direction of the display cover relative to the base.

[0010] Furthermore, the first connecting portion includes two insertion posts, which are located on both sides of the notch.

[0011] In some embodiments, a support plate is provided in the notch, and the support plate is located between the two insertion posts; when the opening edge of the display cover is nested into the groove, the convex edge abuts against the support plate.

[0012] Furthermore, the width of the recess on the locking component is such that it can simultaneously accommodate both the protruding edge and the support plate.

[0013] In some embodiments, there are two notches, each located at the midpoint of one of the two opposite sidewalls of the base.

[0014] In some embodiments, the present invention also includes a handle for easy carrying, and the upper end of the display cover is provided with a snap-fit ​​position, and both ends of the handle are snapped into the snap-fit ​​position.

[0015] In some embodiments, the display cover is a transparent bento box-shaped cover.

[0016] In some embodiments, the top surface of the base is provided with evenly spaced splicing protrusions for assembling building blocks.

[0017] The beneficial effects of this utility model are: by connecting the display cover to the base through the locking component, the convex edge of the display cover is confined in the cavity of the locking component, ultimately achieving a locking connection between the display cover and the base. This connection and fixing method is simple to operate and ensures a firm connection between the display cover and the base. Therefore, users can carry the display cover by holding it or by lifting it with a handle on the top of the display cover, making it convenient to carry while also providing a display function.

[0018] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] In the description of this utility model, it should be understood that the terms "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "fitting," "connected," "linked," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The portable display box of this utility model will now be described with reference to the accompanying drawings.

[0025] like Figure 1As shown, this utility model relates to a portable display box, including a display cover 1 and a base 2. The display cover 1 and the base 2 are fitted together to form a display box. The base 2 is characterized by having four side walls 21, a top surface 22 facing the display cover 1, and a bottom surface opposite to the top surface 22 (not shown in the figure). A gap is provided between the edge of the top surface 22 and the four side walls 21 to form a groove 23. Since the base 2 is an integral part, it can be expected that the bottom surface must be connected to the four side walls 21 as a whole. At least two sidewalls 21 are recessed at their central positions toward the edge of the top surface 22 to form notches 24, and a first connecting part 25 is provided at the notch 24; correspondingly, the opening edge of the display cover 1 extends outward at the position corresponding to the notch 24 with a protruding edge 11. When the opening edge of the display cover 1 is nested into the groove 23, the protruding edge 11 is located at the notch 24; it also includes locking components 4, the number of which is the same as the number of notches 24. The locking components 4 are provided with a second connecting part 42 and a cavity 41 for the protruding edge 11 to extend into. After the second connecting part 42 of the locking components 4 is connected to the first connecting part 25, the protruding edge 11 extends into the cavity 41. At this time, the display cover 1 cannot be separated from the locking components 4. At the same time, the locking components 4 are connected to the base 2, thus realizing the locking of the display cover 1 and the base 2. The display cover 1 can only be opened after the locking components 4 are separated from the base 2. This utility model uses a locking component 4 to connect and fix the base 2, which is simple to operate and ensures that the display cover 1 and the base 2 are firmly connected. Therefore, users can hold the display cover 1 or carry it by lifting it with a handle 3 on the upper end of the display cover 1, which is convenient to carry and also has a display function.

[0026] Understandably, the structural style of the notch 24 on the side wall 21 can be: a notch 24 with four walls, so as to... Figure 2 Taking the XYZ axis coordinates shown as an example, the four walls of the notch 24 include two side walls parallel to the YZ plane formed by axes Y and Z, one side wall parallel to the XZ plane formed by axes X and Y, and one bottom wall parallel to the XZ plane formed by axes X and Z. The side wall parallel to the XZ plane can serve as a supporting surface for the protruding edge 11 of the display cover 1; alternatively, the notch 24 can have three walls, similarly... Figure 2 Taking the XYZ axis coordinates shown as an example, the three walls of the notch 24 include two side walls parallel to the YZ plane formed by the Y axis and the Z axis, and a bottom wall parallel to the XZ plane formed by the X axis and the Z axis. Figure 2 The structure shown with notch 24 has only these three walls.

[0027] Understandably, the connection direction between the locking component 4 and the base 2 can be various, such as... Figure 1Taking the XYZ axis coordinates shown as an example, the connection direction between the locking component 4 and the base 2 can be along the Y-axis, along the X-axis or Z-axis, or with various directions having a certain angle. Of course, to ensure a more secure connection between the display cover 1 and the base 2 after the locking component 4 is connected, a preferred option is that the connection direction of the second connecting part 42 relative to the first connecting part 25 is opposite to or perpendicular to the nesting direction of the display cover 1 relative to the base 2. Figure 1 Taking the coordinates shown as an example, if the nesting direction of the display cover 1 relative to the base 2 is the Z-axis direction and downward, then the preferred choice for the connection direction of the second connecting part 42 relative to the first connecting part 25 is the Z-axis direction and upward (i.e., the opposite direction) or along the X-axis / Y-axis direction (i.e., the vertical direction).

[0028] Understandably, at least two sidewalls 21 are recessed at their central positions towards the edge of the top surface 22 to form notches 24, meaning at least two notches 24 must be provided. These two notches 24 can be provided on two adjacent sidewalls 21 or on two symmetrical sidewalls 21. To ensure the firmness of the connection between the display cover 1 and the base 2, a preferred solution is that the two notches 24 are located at the central positions of two opposite sidewalls 21 of the base 2. Of course, three or four notches 24 can also be provided to increase the number of locking components 4 and improve the firmness of the connection between the display cover 1 and the base 2. Alternatively, multiple notches 24 can be provided on one sidewall 21, for example, two notches 24 on one sidewall 21 for two locking components 4 to connect.

[0029] The first connecting part 25 and the second connecting part 42 of this utility model can be a plug-in part, a snap-fit ​​part, or other components that are simple to operate and can achieve locking. For example... Figure 2 and Figure 4 In the embodiment shown, the first connecting portion 25 is a plug-in post. The length direction of the plug-in post is consistent with the recessed direction of the notch 24, that is, the plug-in post extends from the bottom wall surface of the notch 24. Figure 2 As shown; the corresponding second connecting part 42 is a plug-in hole, as shown. Figure 4 As shown, in this embodiment, the insertion direction of the plug and the plug hole is perpendicular to the nesting direction of the display cover 1 relative to the base 2. Alternatively, the first connecting part 25 can be a plug hole, and the second connecting part 42 can be a plug. To further ensure a secure connection between the locking component 4 and the base 2, the first connecting part 25 in this embodiment includes two plugs, which are located on either side of the notch 24.

[0030] The fitting manner between the concave cavity 41 on the locking and connecting part 4 of the utility model and the convex edge 11 of the display cover 1 can be that after the second connecting part 42 of the locking and connecting part 4 is connected to the first connecting part 25, the convex edge 11 extends into the concave cavity 41. The way of full extension means that the size of the concave cavity 41 is the same as or slightly larger than that of the convex edge 11, and the whole convex edge 11 extends into the concave cavity 41; it can also be semi-extension, that is, the size of the concave cavity 41 is smaller than that of the convex edge 11, and the convex edge 11 partially extends into the concave cavity 41. For example, there are two concave cavities 41 which are respectively on both sides of the convex edge 11, and the two sides of the convex edge 11 respectively extend into the concave cavities 41 for fitting, while the middle part of the convex edge 11 is exposed outside the concave cavity 41.

[0031] As Figure 2 shown in the embodiment, a supporting plate 26 is provided in the notch 24 of the base 2 of this embodiment, and the supporting plate 26 is located at the position between the two inserting columns; therefore, when the opening edge of the display cover 1 is nested into the groove 23, the convex edge 11 abuts against the supporting plate 26. Such a design can protect the convex edge 11 and avoid accidentally bending or breaking the convex edge 11 when inserting the locking and connecting part 4. Further, the width of the concave cavity 41 on the locking and connecting part 4 can accommodate at least the convex edge 11 and the supporting plate 26 simultaneously, as Figure 5 shown, that is, the locking and connecting part 4 sleeks both the convex edge 11 and the supporting plate 26 into the concave cavity 41, thereby improving the connection firmness between the display cover 1 and the base 2.

[0032] For more convenient carrying, as Figure 3 shown, this embodiment further includes a handle 3 for convenient hand carrying. The handle 3 is in a "冂" shape and is composed of two handle parts 31 docked. Then, a clamping position 12 is provided at the upper end of the display cover 1, and both ends of the handle 3 are clamped into the clamping position 12, thereby realizing the fixed connection between the handle 3 and the display cover 1. With such a design, when the display box needs to be carried, the display box can be carried and transported with one hand holding the handle 3, without holding the display box in arms or holding the base 2, so it is more convenient to carry.

[0033] The display cover 1 of the utility model is made of a transparent material, so as to more conveniently and comprehensively display the internal items; of course, it can also be partially made of a transparent material or have a window, and other positions are made of a non-transparent material. Further, in order to improve its aesthetics, the display cover 1 can also be designed into a lunch box-shaped cover body, as Figure 1 or Figure 3 shown.

[0034] The base 2 of the utility model can be used for users to place items. When it is needed to place building block items, as Figure 2In the embodiment shown, the top surface 22 of the base 2 is provided with evenly spaced splicing protrusions 5 for assembling building blocks. This allows assembled building block items to be attached to the base 2, thereby improving the fit between the building block items and the base 2 and ensuring that the building block items will not slide inside the display box when the display box is being carried.

[0035] In this specification, the terms "embodiment," "example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
