[0036] As 3D printers become increasingly popular, printing consumables are becoming more diverse. Currently, most 3D printer consumables are exposed outside the machine, making them susceptible to environmental influences. Moisture molecules in the environment can cause the consumables to become damp, leading to stringing during printing and even breakage. To reduce the impact of environmental moisture on 3D printer consumables, existing technologies offer solutions that place the consumables inside a consumable box. However, this presents challenges in removing and maintaining the consumables.

[0037] To address this issue, this embodiment provides a printer consumables box to solve the problem of consumables being difficult to remove and maintain. It can be used in the field of printer technology, specifically in 3D printers.

[0038] Reference Figures 1-8 The printer consumables box includes a first box body 1 and a second box body 2. The first box body 1 and the second box body 2 are detachably connected along a first direction. The printer consumables box also includes a locking member 3 connected to the first box body 1. The second box body 2 is connected to a mounting shaft 21 for installing consumables 100. The end of the mounting shaft 21 is provided with a limiting plate 22. The locking member 3 is movably connected to the second box body 2, and the locking member 3 can abut against the limiting plate 22 along the first direction to prevent the first box body 1 from moving relative to the second box body 2, thereby achieving locking between the first box body 1 and the second box body 2. The locking member 3 can also be offset from the limiting plate 22 along the first direction so that the first box body 1 can move relative to the second box body 2 along the first direction, thereby unlocking the first box body 1 and the second box body 2. The user can remove the first box body 1 relative to the second box body 2 along the first direction to replace or maintain the consumables 100. In addition, the printer consumable box is locked or unlocked by the locking component 3 and the limiting plate 22. The limiting plate 22 is integrated into the mounting shaft 21, which has a simple structure and can save space inside the printer consumable box.

[0039] Continue to refer to Figures 1-8The locking element 3 includes a rotating shaft 31 that rotatably passes through the first housing 1 and a locking block 32 protruding from the outer peripheral wall of the rotating shaft 31. The axes of the mounting shaft 21 and the rotating shaft 31 both extend along a first direction. The rotating shaft 31 remains fixed in position relative to the first housing 1. The locking element 3 can rotate relative to the first housing 1 to have a locked position and an unlocked position. When the locking element 3 is in the locked position, the locking block 32 abuts against the limiting plate 22 along the first direction, and the limiting plate 22 is located between the first housing 1 and the locking block 32. This prevents the locking block 32 from moving, thereby preventing the first housing 1 from moving relative to the second housing 2, thus achieving locking between the first housing 1 and the second housing 2. When the locking element 3 is in the unlocked position, the locking block 32 and the limiting plate 22 are offset along the first direction, thereby unlocking the first housing 1 and the second housing 2. The user can then remove the first housing 1 relative to the second housing 2 along the first direction.

[0040] Continue to refer to Figures 1-8 The limiting plate 22 is located on the end face of the mounting shaft 21. The mounting shaft 21 has a cavity inside. The limiting plate 22 has an opening 221 that communicates with the cavity. The locking block 32 can enter and exit the cavity through the opening 221 in the first direction. So when the position between the first box 1 and the second box 2 is locked by the locking member 3, the locking block 32 extends into the interior of the mounting shaft 21 to further save space inside the printer consumable box.

[0041] Optionally, two locking blocks 32 are provided, with each locking block 32 disposed on one side of the outer peripheral wall of the rotating shaft 31, so that when the two locking blocks 32 abut against the limiting plate 22, both sides of the rotating shaft 31 are simultaneously subjected to force. In addition, in other embodiments, multiple locking blocks 32 may be provided, with the multiple locking blocks 32 spaced apart along the circumferential direction of the rotating shaft 31.

[0042] Continue to refer to Figures 1-8 The outer peripheral wall of the rotating shaft 31 is also provided with a limiting block 33. The first housing 1 is provided with a first limiting part 11 and a second limiting part 12 at intervals. When the locking member 3 is in the locked position, the limiting block 33 abuts against the first limiting part 11 along the circumferential direction of the rotating shaft 31. When the locking member 3 is in the unlocked position, the limiting block 33 abuts against the second limiting part 12 along the circumferential direction of the rotating shaft 31. Thus, when the locking member 3 moves to the locked position or the unlocked position, the limiting block 33 is prevented from continuing to move, thereby limiting the range of movement of the locking member 3 relative to the first housing 1 and preventing it from moving excessively. In this embodiment, the first housing 1 has an opening 14 for the rotating shaft 31 to pass through. The limiting block 33 is also provided in the opening 14, and the first limiting part 11 and the second limiting part 12 are both the walls of the opening 14.

[0043] Continue to refer to Figures 1-8The outer peripheral wall of the rotating shaft 31 is also provided with an annular protrusion 34, and the end of the rotating shaft 31 is also provided with a fixing plate 35. The annular protrusion 34 is located between the fixing plate 35 and the locking block 32. The first box 1 is sandwiched between the annular protrusion 34 and the fixing plate 35, thereby limiting the position of the locking member 3 along the first direction by the annular protrusion 34 and the fixing plate 35, so that the locking member 3 can only rotate relative to the first box 1, but cannot move along the first direction, thus preventing the locking member 3 from disengaging from the first box 1. Optionally, the limiting block 33 is connected to the annular protrusion 34, which simplifies the structure, facilitates processing, and enhances its structural strength.

[0044] Continue to refer to Figures 1-8 A knob 351 is fixedly provided on the side of the fixing plate 35 away from the locking block 32 so that the user can operate it by hand. The user can rotate the locking member 3 relative to the first box 1 by turning the knob 351.

[0045] Continue to refer to Figures 1-8 The fixing plate 35 has a protruding rib 352 on the side near the locking block 32. The rib 352 abuts against the first box body 1 to reduce the contact area between the locking member 3 and the first box body 1. This can reduce frictional resistance when relative movement occurs between the two.

[0046] Optionally, the rotating shaft 31 is provided with a number of notches 311, which extend toward the annular protrusion 34 and penetrate through the annular protrusion 34, thereby dividing the rotating shaft 31 and the annular protrusion 34 into several parts. Each part of the rotating shaft 31 and the annular protrusion 34 is connected to the fixing plate 35. In addition, the rotating shaft 31 has a certain elasticity, and the annular protrusion 34 can be used as a hook. When installing the locking member 3, the locking member 3 can be inserted from the opening 14 and locked onto the first housing 1 through the annular protrusion 34.

[0047] Continue to refer to Figures 1-8One of the first housing 1 and the locking member 3 is connected to an elastic arm 13. The elastic arm 13 is capable of elastic deformation along a first direction and is provided with a protrusion 131. The other part has a first groove 353 and a second groove 354. When the locking member 3 is in the locked position, the protrusion 131 is inserted into the first groove 353; when the locking member 3 is in the unlocked position, the protrusion 131 is inserted into the second groove 354. Thus, when the locking member 3 is in the locked or unlocked position, the protrusion 131 can be inserted into the corresponding groove. On the one hand, it can remind the user that it has been rotated to the correct position; on the other hand, it can prevent the locking member 3, which is already in the locked or unlocked position, from rotating on its own. This embodiment exemplarily provides a scheme in which the elastic arm 13 is provided in the first housing 1, and the first groove 353 and the second groove 354 are provided in the locking member 3. Further, the first groove 353 and the second groove 354 are both formed in the fixing plate 35. The first housing 1 also has a connecting hole 15 communicating with the opening 14, and the elastic arm 13 is disposed in the connecting hole 15.

[0048] Optionally, the first housing 1 is also provided with a label 17 to remind the user of the current position of the locking element 3.

[0049] Optionally, the first housing 1 has a mounting groove 18, the fixing plate 35 of the locking member 3 is disposed in the mounting groove 18 and can rotate in the mounting groove 18, and the opening 14 and the connecting hole 15 are both opened on the bottom wall of the mounting groove 18.

[0050] Continue to refer to Figures 1-8 The first box 1 has a slot 16, and the second box 2 has a flange 23. The flange 23 is inserted into the slot 16 along a first direction, thereby realizing the installation between the first box 1 and the second box 2. Optionally, the first box 1 has a structural member 161 inside, and the inner wall of the first box 1 and the structural member 161 form a slot 16. The inner wall of the first box 1 and the structural member 161 can respectively abut against the two sides of the second box 2, thereby making the first box 1 and the second box 2 stably connected.

[0051] Optionally, the second box 2 is provided with a number of support protrusions 24 on the side away from the first box 1. The surfaces of the multiple support protrusions 24 on the side away from the first box 1 are flush, so that the user can place the printer consumable box stably on the table through the multiple support protrusions 24, which is convenient for the user to perform subsequent operations.

[0052] This embodiment also provides a 3D printer, including the above-mentioned printer consumable box and a frame. The second box 2 is disposed on the frame. In the printer consumable box, the locking or unlocking between the first box 1 and the second box 2 can be achieved by the cooperation of the locking member 3 and the limiting plate 22. In addition, the limiting plate 22 is integrated into the mounting shaft 21, which has a simple structure and can save space inside the printer consumable box.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
