[0003] Most existing pencil cases are single-layer or double-layer. For two-layer pencil cases, the height between the first layer and the second layer is generally fixed, so the space between the first layer and the second layer is also fixed. This causes stationery with a thick bottom, such as a ruler, to shake greatly in the pencil case, or stationery with a thicker thickness, such as an eraser, cannot be put in, making it inconvenient to use. Utility Model Content

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-5 The utility model discloses a novel pencil case with controllable storage space, comprising a pencil case body 1, an upper storage box 2 being slidably arranged between the side walls of the pencil case body 1, and a placement plate 16 being provided on both side walls of the pencil case body 1, the placement plate 16 being fitted with the lower end of the upper storage box 2, and a lifting member being provided on one side of the placement plate 16;

[0025] The lifting member includes an adjustment groove 15 opened in the pencil case body 1, and a slider 10 is slidably connected between the side walls of the adjustment groove 15. One side of the slider 10 is connected to the placement plate 16 by sliding. A side wall of the adjustment groove 15 is rotatably connected to the winding drum 7, and the circumferential side of the winding drum 7 is fixedly connected to the traction rope 9, and the lower end of the traction rope 9 is fixed to the slider 10.

[0026] In this embodiment, the upper storage box 2 is directly placed on the two placement plates 16. When the space between the upper storage box 2 and the inner bottom wall of the pencil case main body 1 needs to be adjusted, the winding drum 7 is rotated, and the limit rod 8 is gradually wrapped around the circumferential side of the winding drum 7. The winding drum 7 pulls the slider 10 to move upward, and the slider 10 can drive the placement plate 16 to move upward. By adjusting the height between the upper storage box 2 and the inner bottom wall of the pencil case main body 1, the space between the upper storage box 2 and the pencil case main body 1 is increased, and vice versa, the winding drum 7 is reversed. Rotation, preferably the friction between the rotating shaft on the winding drum 7 and the adjusting groove 15 is large, which can prevent lighter gravity from driving the winding drum 7 to rotate, and the traction rope 9 is separated from the surface of the winding drum 7, pushing the upper storage box 2 downward, and the upper storage box 2 can move downward, thereby reducing the space between the upper storage box 2 and the inner wall of the pencil case body 1. The upper storage box 2 is suitable for placing some pens, and some rulers, erasers, etc. can be placed at the bottom of the pencil case body 1. Both side walls of the upper storage box 2 are provided with a taking slot 4.

[0027] For further details, please refer to Figure 1The rotating shaft of the winding drum 7 is fixedly connected to the rotating roller 6, and the circumferential side of the rotating roller 6 moves through the upper end of the pencil case body 1.

[0028] In this embodiment, rotating the rotating roller 6 can drive the winding drum 7 to rotate. A rectangular hole can be opened at the rotating shaft of the rotating roller 6, and a rectangular plug is inserted into the rotating roller 6 to limit the rotation of the rotating roller 6. The friction between the rectangular plug and the rectangular hole is larger to prevent the rectangular plug from falling off in the absence of external force.

[0029] For further details, please refer to Figure 5 Two limiting rods 8 are fixedly connected between the inner top wall and the inner bottom wall of the pencil case body 1 , and the slider 10 is slidably connected to the circumferential sides of the two limiting rods 8 .

[0030] In this embodiment, the slider 10 moves linearly up and down on the surface of the limiting rod 8, which can improve the movement stability of the slider 10.

[0031] For further details, please refer to Figure 2 Both side walls of the upper storage box 2 are provided with a plurality of T-shaped mounting grooves 5 , and a partition plate 3 is provided in the upper storage box 2 , and both sides of the partition plate 3 are slidably connected to the T-shaped mounting grooves 5 .

[0032] In this embodiment, T-shaped blocks that match the shape of the T-shaped mounting groove 5 are fixed on both sides of the partition plate 3. The T-shaped blocks can be inserted into the T-shaped mounting groove 5, and the position of the partition plate 3 can be adjusted to divide the space in the upper storage box 2.

[0033] For further details, please refer to Figure 3 A clamping plate 13 is slidingly provided on the inner bottom wall of the pencil case body 1. Two clamping grooves 11 are opened in the pencil case body 1. A connecting block 12 is slidingly connected between the side walls of the clamping groove 11, and the upper end of the connecting block 12 movably passes through the inner bottom wall of the pencil case body 1 and is fixed to the clamping plate 13.

[0034] In this embodiment, objects are placed on both sides of the clamping plate 13. For example, erasers, due to their own size, squeeze the clamping plate 13. The clamping plate 13 is moved, and the clamping plate 13 can separate the stationery.

[0035] For further details, please refer to Figure 4 A clamping spring 14 is fixedly connected to one side wall of the clamping groove 11 , and the other side of the clamping spring 14 is fixed to the connecting block 12 .

[0036] In this embodiment, objects are placed on both sides of the clamping plate 13. For example, an eraser or the like squeezes the clamping plate 13 due to its own size, and the clamping spring 14 is in a compressed or stretched state. The clamping spring 14 can make the clamping plate 13 fit more closely to the eraser ruler or the like through its own elasticity, and perform micro-clamping on it to reduce the shaking of the stationery.

[0037] The implementation principle of the above embodiment is as follows: the upper storage box 2 is directly placed on the two placement plates 16. When the space between the upper storage box 2 and the inner bottom wall of the pencil case main body 1 needs to be adjusted, the winding drum 7 is rotated, and the limit rod 8 is gradually wrapped around the circumferential side of the winding drum 7. The winding drum 7 pulls the slider 10 to move upward, and the slider 10 can drive the placement plate 16 to move upward. By adjusting the height between the upper storage box 2 and the inner bottom wall of the pencil case main body 1, the space between the upper storage box 2 and the pencil case main body 1 is increased. On the contrary, the winding drum 7 rotates in the opposite direction, and the traction rope 9 disengages from the surface of the winding drum 7, pushing the upper storage box 2 downward, and the upper storage box 2 can move downward, thereby reducing the space between the upper storage box 2 and the inner wall of the pencil case main body 1, making it more convenient to adjust the storage space in the pencil case main body 1 and convenient to use.

[0038] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
