[0037] The following will describe the implementation methods of the present invention in detail in conjunction with specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0038] Example

[0039] like Figures 1 to 7 As shown, a double-sided pencil case includes at least one cover plate 1 and a bottom box 2, wherein the bottom box 2 is provided with at least one placement cavity 21 with an opening facing upward, each of the cover plates 1 is provided above the bottom box 2 for covering the opening corresponding to each of the placement cavities 21, and further includes an opening and closing component 3, wherein at least one side of each of the cover plates 1 is connected to the bottom box 2 through the opening and closing component 3, and each of the opening and closing components 3 is a detachable connection structure, and when one side of each of the cover plates 1 is separated from the bottom box 2, each of the cover plates 1 can be flipped relative to the bottom box 2 along the other side, and the opening and closing component 3 includes:

[0040] at least one rotating rod 4;

[0041] A fixing ring 5, at least one fixing ring 5 is sleeved on each of the rotating rods 4;

[0042] A pressing component 6, a pressing opening 22 is provided on the outer side of the bottom box 2, and the pressing component 6 is provided at the pressing opening 22;

[0043] At least one elastic member 7 is used for storing energy when the pressing member 6 is pressed and causing the fixing ring 5 to be separated from the rotating rod 4 , and releasing energy when the pressing member 6 is released and causing the fixing ring 5 to be re-mounted on the rotating rod 4 .

[0044] In this embodiment, a placement cavity 21 and a cover plate 1 are provided on the base box 2. The cover plate 1 is connected to the base box 2 on both sides in the length direction through opening and closing components 3, wherein the opening and closing components 3 include two rotating rods 4, two fixing rings 5, two elastic members 7 and a pressing component 6, and a fixing ring 5 is sleeved on one rotating rod 4; when one side of the opening and closing components 3 is pressed, the cover plate 1 can be flipped along the other side relative to the base box 2, and when the opening and closing components 3 on both sides are pressed at the same time, the cover plate 1 can be directly removed.

[0045] The cover plate 1 and the bottom box 2 of the present application are connected via an opening and closing component 3, which can not only support direct separation of the cover plate 1 and the bottom box 2, but also support flipping of the cover plate 1 relative to the bottom box 2, making the cover plate 1 easy to disassemble; when opening and closing components 3 are provided on both sides of the cover plate 1 to connect with the bottom box 2, direct connection and separation of both sides of the cover plate 1 and the bottom box 2 can be achieved, and at the same time, when one side of each of the cover plates 1 is in a separated state from the bottom box 2, each of the cover plates 1 can be flipped relative to the bottom box 2 along the other side.

[0046] like Figure 4 As shown, in other preferred embodiments, two placement cavities 21 can be further provided on the bottom box 2, corresponding to the two cover plates 1, wherein the opening and closing component 3 includes a rotating rod 4, a fixing ring 5, an elastic member 7 and a pressing component 6. To simplify the structure, the two opening and closing components 3 on the same side can share a pressing component 6. The basic structure is basically the same as that in the present embodiment, except that there are two cover plates 1, so that stationery can be stored in partitions. Figure 4 The structure shown in the figure shows two equal-sized placement cavities 21; in addition, in other preferred implementations, the sizes of the two placement cavities 21 can be one large and one small, and the large placement cavity 21 can be used to place large items such as pens and compasses, and the small placement cavity 21 can be used to place small items such as erasers.

[0047] The pressing component 6 includes a pressing plate 61, a first limit block 62 and a second limit block 63. The first limit block 62 is arranged on the inner side of the pressing plate 61. In the present embodiment, the second limit block 63 is arranged at one end of the rotating rod 4. The first limit block 62 is in contact with the second limit block 63. The contact surface between the first limit block 62 and the second limit block 63 is an inclined surface. In the present embodiment, the opening and closing component 3 includes two elastic members 7. Each of the elastic members 7 adopts a wavy elastic sheet. Each of the elastic members 7 is arranged on one side of each of the rotating rods 4.

[0048] Among them, the stored energy of the elastic member 7 is converted into the elastic force of the elastic member 7 through the contact between the first limit block 62 and the second limit block 63. When the finger presses the pressing plate 61, the second limit block 63 moves along the inclined surface, driving the rotating rod 4 to move, and then compressing the wavy elastic sheet. In order to prevent the elastic member 7 from moving with the rotating rod, it is only necessary to set a protrusion 23 at the corresponding position on the bottom box 2 to clamp one end of the elastic member 7.

[0049] like Figure 5 As shown, in other preferred embodiments, the opening and closing component 3 can also include only one elastic member 7, and the two rotating rods 4 are connected by the elastic member 7. Compared with the structure of two elastic members 7, the structure of one elastic member 7 is simpler and more convenient to assemble. During production, the rotating rod 4 and the elastic member 7 can be directly obtained as an integral part through mold molding, which can reduce the production process and reduce costs.

[0050] In other preferred embodiments, each of the elastic members 7 may also adopt a V-shaped elastic sheet (not shown in the figure). Compared with the wavy elastic sheet, the V-shaped elastic sheet has a smaller span, stores less energy, and can be compressed to a smaller length, and is more suitable for the pressing component 6 that cooperates with the small placement cavity 21.

[0051] In other preferred embodiments, each of the elastic members 7 can also adopt a spring (not shown in the figure). In this case, the elastic member 7 is sleeved on the rotating rod 4. When the elastic member 7 adopts a wavy elastic sheet or a V-shaped elastic sheet, for ease of production, its material is the same plastic material as the rotating rod 4. Its elastic force storage effect will weaken with the increase of the number of uses. When the elastic member 7 adopts a spring, the elastic force storage effect is more stable and has a longer service life.

[0052] like Figure 6 As shown, in other preferred embodiments, each of the elastic members 7 is disposed at one end of each of the fixing rings 5; compared with the elastic member 7 being disposed at one end of the rotating rod 4, when it is disposed at one end of the fixing ring 5, the rotating rod 4 can be set to a shorter length, which can save consumables of the component.

[0053] In this embodiment, two rotation grooves 24 are provided on the bottom box 2 , and each of the fixing rings 5 ​​is disposed in the rotation groove 24 . In other preferred embodiments, the number of the rotation grooves 24 is adjusted according to the number of the fixing rings 5 ​​.

[0054] The bottom of the pressing plate 61 is rotatably connected to the bottom box 2 , and blocks 611 are provided on both sides of the pressing plate 61 ; the setting of the blocks 611 is used to stabilize the position of the pressing plate 61 . In the present embodiment, the blocks 611 and the first limiting blocks 62 are integrally formed.

[0055] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
