The existing pencil case usually includes a box body, a box cover that is buckled with the box body, and a locking buckle. Multiple boxes can be stacked and combined to expand the storage space for pens. However, the existing pencil case still has many shortcomings, such as Figure 1 The figure shows a partial schematic diagram of a pencil case in the prior art. After a plurality of boxes are stacked and assembled, locking buckles are required to lock and connect them one by one. The lock buckles on adjacent boxes will interfere with each other, making it inconvenient to lock and the user experience is poor. Utility Model Content

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a multi-layer pencil case with anti-interference buckles. The present invention limits the range of motion of the buckles by limiting the position of the buckles to prevent interference between adjacent buckles when locking. The utility model has the advantages of being easier to use and providing a better user experience.

It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0022] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0023] like Figures 2 to 5 FIG. 1 is an embodiment of the present invention, a multi-layer pencil case with anti-interference snap fasteners, comprising a main box body 1, a box cover 2 snapped together with the main box body 1, and a snap fastener 3. The main box body 1 is locked and connected to the box cover 2 via the snap fastener 3. The pen case further comprises at least one sub-box body 4 having the same structure as the main box body 1. The main box body 1 is stacked on top of the sub-box body 4 and is also locked and connected together via the snap fastener 3. The pen case further comprises a connecting portion for movable connection of the snap fastener 3 and a limiter for limiting the movable range of the snap fastener 3.

[0024] The beneficial effects of such a setting are as follows: the utility model limits the range of movement of the buckle through the limiter to prevent adjacent buckles from interfering with each other when locking, that is, adjacent buckles will not contact each other whether in the unlocked state or the locked state, and any buckle can be unlocked or locked individually, which has the advantages of being more convenient to use and providing a better user experience.

[0025] It is further provided that the connecting portion includes a pin shaft 5 and a locking block 6, and the main box body 1 and the auxiliary box body 4 are both fixed with a pin shaft 5 for rotationally connecting the buckle 3, and the box cover 2, the main box body 1 and the auxiliary box body 4 are all fixed with a locking block 6 that locks with the buckle 3, and the buckle 3 is provided with an axial hole 7 that is adapted to the pin shaft 5, and the end of the buckle 3 away from the axial hole 7 is provided with a connecting block 8 that is adapted to the locking block 6.

[0026] The beneficial effects of such a setting are as follows: the buckle is rotatably connected to the pin shaft through the shaft hole, and then locked by the snap block and the locking block, that is, the buckle is installed on the main box body and the sub-box body in a hinged connection manner. There is only a locking block on the box cover, and there is also a locking block under the main box body for locking the buckle of the sub-box body stacked below. The locking block under the sub-box body is similarly used to lock the buckle of the sub-box body that continues to be stacked below. The buckle is locked when it is rotated upward and unlocked when it is rotated downward.

[0027] It is further provided that the limit member includes a limit block 9 arranged on the outer periphery of the pin shaft 5 and protruding radially along the pin shaft 5, and a clearance groove 10 for the limit block 9 to slide into is opened on the inner wall of the shaft hole 7, and the inner wall of the clearance groove 10 is provided with an abutment surface 11 that blocks the limit block 9. When the buckle 3 rotates until the limit block 9 abuts against the abutment surface 11, the buckle 3 cannot continue to rotate in the same direction.

[0028] The beneficial effects of this arrangement are as follows: the limit block is arranged on the pin shaft to block the rotation of the limit buckle. When the buckle is rotated downward to unlock, the limit block and the abutment surface abut against each other to form a blocking limit, that is, the rotation angle of the buckle is limited, and the buckle will not contact the buckle on the box body stacked below, and each buckle can be easily unlocked and locked.

[0029] It is further provided that the pin shaft 5 is a cylinder, and a mounting groove 12 is provided on one side wall of the shaft hole 7 . The width of the mounting groove 12 is smaller than the diameter of the pin shaft 5 and the length is greater than the axial length of the pin shaft 5 .

If either the clip or the pin is made of slightly deformable materials such as plastic, the pin can pass through the mounting slot.

[0031] Furthermore, guide slopes 13 are provided on both inner walls of the installation groove 12 .

[0032] The beneficial effect of such a setting is as follows: the pin can slide into the shaft hole more effortlessly through the guiding inclined surface.

[0033] It is further provided that the clearance groove 10 and the installation groove 12 both penetrate the side wall of the shaft hole 7 and have the same opening direction, and the abutting surface 11 is coplanar with the inner wall of the installation groove 12 on the side away from the clamping block 8.

[0034] The beneficial effect of this arrangement is as follows: the buckle can be disassembled from the pin shaft only when it is rotated to the position where the limit block and the abutment surface abut against each other, and the pin shaft will not cause interference during disassembly and assembly.

[0035] It is further provided that there are two pin shafts 5 , and shaft holes 7 corresponding to the pin shafts 5 are opened on both sides of the buckle 3 , and the buckle 3 is limited between the two pin shafts 5 .

[0036] The beneficial effects of this arrangement are as follows: the buckle rotates with the two pins at the same time, the rotation is more stable, the installation is more secure, and it will not fall off at will.

[0037] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
