Description

Technical Field

[0001] The utility model relates to the technical field of stationery, in particular to a double-sided pencil case. Background Art

[0002] Chinese Patent Publication No. CN114869036A discloses a pencil case comprising a bottom shell, an upper cover, a sliding structure, and a sliding connection structure. The bottom shell is provided with a stationery storage cavity with an upward opening, the upper cover is provided on the upper side of the bottom shell and is used to cover the opening of the stationery storage cavity, the sliding structure connects the rear side of the bottom shell and the rear side of the upper cover, and the sliding connection structure connects the front side of the bottom shell and the front side of the upper cover. The upper cover can slide left and right relative to the bottom shell via the sliding structure and the sliding connection structure to open at least a portion of the stationery storage cavity; the sliding connection structure is a detachable connection structure, so that the front side of the bottom shell and the front side of the upper cover can be detached from each other. After the front side of the bottom shell and the front side of the upper cover are detached from each other, the upper cover can be rotated and flipped open relative to the bottom shell via the sliding structure.

[0003] This invention enables the upper cover to be rotated and flipped open relative to the bottom shell by the sliding connection structure and the sliding structure. However, due to the structural design of the sliding connection structure and the sliding structure, the upper cover cannot be rotated and flipped open by the sliding connection structure. That is, in the solution provided by this utility model, the upper cover can only be flipped open on one side, which will be restricted if it needs to be flipped open during use. The separation of the upper cover and the bottom shell requires opening the sliding connection structure and then sliding the upper cover to the left and right to remove the upper cover, which is inconvenient to use.

[0031] The following will describe the implementation methods of the present invention in detail with reference to 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.

[0032] Example

[0033] like Figures 1 to 4 As shown, a double-sided pencil case includes a cover plate 1 and a bottom box 2. The bottom box 2 is provided with a placement cavity 21 with an opening facing upward. The cover plate 1 is provided above the bottom box 2 for sealing the opening of the placement cavity 21. It also includes an opening and closing component 3. One side of the cover plate 1 is connected to the bottom box 2 through the opening and closing component 3. The opening and closing component 3 is a detachable connection structure. When one side of the cover plate 1 is separated from the bottom box 2, the cover plate 1 can be flipped relative to the bottom box 2 along the other side. The opening and closing component 3 includes:

[0034] Two rotating rods 4;

[0035] A fixing ring 5 is provided on each rotating rod 4;

[0036] A pressing member 6 is provided with a pressing opening 22 on the outside of the bottom box 2. The pressing member 6 is provided at the pressing opening 22. The pressing member 6 includes a pressing plate 61, a first limiting block 62 and a second limiting block 63. The first limiting block 62 is provided on the inner side of the pressing plate 61, and the second limiting block 63 is provided at one end of the rotating rod 4. The first limiting block 62 contacts the second limiting block 63, and the contact surface between the first limiting block 62 and the second limiting block 63 is an inclined surface.

[0037] Two elastic members 7 are used to store energy when the pressing member 6 is pressed and to separate the fixing ring 5 from the rotating rod 4 , and to release energy when the pressing member 6 is released and to re-sleeve the fixing ring 5 on the rotating rod 6 .

[0038] The cover plate 1 and the bottom box 2 of the present application are connected through the opening and closing component 3. The opening and closing component 3 can not only support the direct separation of the cover plate 1 and the bottom box 2, but also support the flipping of the cover plate 1 relative to the bottom box 2, so that the cover plate 1 is easy to disassemble; when the opening and closing components 3 are provided on both sides of the cover plate 1 to connect with the bottom box 2, the cover plate 1 and the bottom box 2 can be directly connected and separated on both sides. At the same time, when one side of each cover plate 1 is in a separated state from the bottom box 2, each cover plate 1 can be flipped relative to the bottom box 2 along the other side.

[0039] In this embodiment, each elastic member 7 is a wavy elastic sheet, and each elastic member 7 is disposed on one side of each rotating rod 4 .

[0040] In other preferred embodiments, each of the elastic members 7 can also be a spring (not shown in the figure). In this case, the elastic member 7 is sleeved on the rotating rod 4, and its elastic force storage effect will not weaken with the increase in the number of uses. The elastic force storage effect is more stable and has a longer service life.

[0041] 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, and the pressure of the finger pressing the pressing plate 61 is converted into the elastic force of the elastic member 7. 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.

[0042] 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 this embodiment, the blocks 611 and the first limiting blocks 62 are integrally formed.

[0043] The bottom box 2 is provided with two rotation grooves 24 , and each of the fixing rings 5 ​​is disposed in each of the rotation grooves 24 .

[0044] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
