[0033] Please see Figure 1 and Figure 2 This application provides a handle 1, including: a handle body 11, a mounting base 12, and a sealing unit 16. The mounting base 12 is installed on the box to be connected, or the mounting base 12 and the box to be connected are an integrated structure. The handle body 11 and the mounting base 12 are connected by a pivot 13. A buckle is provided at the base of the handle body 11, and a through hole is provided on the mounting base. The buckle passes through the through hole and engages with the box to be connected. The sealing unit 16 is sealed to the mounting base 12 and the buckle in both the buckle engaged and open positions. The mounting base 12 is sealed to the box to be connected. The handle 1 provided in this application solves the technical defects of the prior art, which requires the use of multiple structural components to realize the opening and locking functions of the 3D printer's storage box, resulting in inconvenient operation and easy forgetting.

[0034] In the technical solution provided in this application embodiment, the mounting base 12 is fixed to the box to be connected. Specifically, the mounting base 12 and the box to be connected can be fixed by connection or by an integrated structure. After the handle body 11 and the mounting base 12 are connected by the rotating shaft 13, when the handle body 11 is pulled, the rotating shaft 13 rotates relative to it. The external force of pulling the handle 1 is transmitted to the box to be connected through the rotating shaft 13, and the box to be connected opens after being pulled upward. When locking is required, the handle body 11 falls under the action of gravity, and the buckle at the base of the handle body 11 engages with the box to be connected, thus locking the handle 1 to the box to be connected. Furthermore, the sealing unit 16 seals the connection surface between the handle body 11 and the box to be connected, further protecting the consumables inside the box to be connected.

[0035] The process of opening and locking the container to be connected can be completed simply by pulling or pressing the handle body 11. The structure is simple and easy to operate, which solves the technical defects of the prior art, which requires the use of multiple structural parts to realize the opening and locking function of the 3D printer storage box, making the operation inconvenient and easy to forget.

[0036] To further optimize the technical solution, the handle 1 provided in this application embodiment also includes: an elastic reset member 14, the two ends of which are respectively connected to the handle body 11 and the box to be connected; the elastic reset member 14 is used to limit the handle body 11 to remain in the engaged position, and the handle body 11 rotates around the pivot 13 from the engaged position to the open position. The elastic reset member 14 can promptly reset the handle body 11, preventing it from failing to fully close due to gravity after being pulled up, thus avoiding leakage and loss of consumables inside the box to be connected. At the same time, the elastic reset member 14, while ensuring a good reset effect, also has the advantages of simple structure and easy installation.

[0037] To detect whether the handle body 11 has reached the preset locking position, the handle 1 provided in this embodiment further includes a detection unit. The detection unit includes a magnet 151 and a Hall sensor 152. The magnet 151 is located at the end of the buckle, and the Hall sensor 152 is located on the box to be connected, opposite to the side or bottom of the magnet 151. The detection unit detects the position of the base of the handle body 11. If the base of the handle body 11 has not reached the preset position, the detection unit provides real-time feedback of the detection result, reminding the user to check again and perform subsequent locking steps. Furthermore, while ensuring the good detection effect of the detection unit, and considering the small installation space at the base of the handle body 11, the detection unit needs to be compact and easy to install. The Hall sensor 152 is set in the box to be connected, and the magnet 151 is set in the buckle, which simplifies the wiring of the Hall sensor 152. At this time, when the magnetic field generated by the magnet 151 approaches the Hall sensor 152, the Hall sensor 152 detects the change in magnetic field and converts the change in magnetic field into an electrical signal through the Hall effect, which plays a detection and reminder role.

[0038] To further optimize the technical solution, in the technical solution provided in this application embodiment, the buckle is cylindrical and the magnet 151 is cylindrical. The magnet 151 is semi-openly inserted into the end of the buckle along the axial direction of the buckle. The magnet 151 is located at the end of the buckle, and the displacement value of the magnet 151 is the largest when the rotating shaft 13 rotates, which can effectively improve the sensitivity of sensing with the Hall sensor 152 and further improve the accuracy of the detection unit in detecting the position of the root of the handle body 11.

[0039] To better optimize the sealing effect of the sealing unit 16 and avoid affecting the process of lifting the handle body 11 and the mounting base 12 due to the addition of the sealing unit 16, the sealing unit 16 is arranged in a trapezoidal shape in the technical solution provided in this application embodiment. The wider side of the trapezoid is tightly connected to the mounting base 12, and the narrower side of the trapezoid is tightly connected to the side of the buckle close to the handle body 11. The end of the buckle and the magnet 151 are both arranged through the sealing unit 16.

[0040] To further optimize the technical solution, while ensuring the good sealing effect of the sealing unit 16, the design requirements of easy installation, low cost and good sealing durability of the sealing unit 16 are also taken into account. In the technical solution provided in this application embodiment, the sealing unit 16 is a silicone sealing unit.

[0041] In one implementation, such as Figures 1-2 As shown, the sealing unit is trapezoidal in shape. The wider side of the trapezoid is tightly connected to the mounting base, and the narrower side is tightly connected to the side of the buckle closest to the handle body. The end of the buckle and the magnet both pass through the sealing unit. This design allows the sealing unit to have good deformation capacity, thus ensuring a sealing effect, and also facilitates buckle assembly.

[0042] In one implementation, such as Figures 1-2 As shown, the pivot 13 is mounted on the side of the buckle near the handle body 11, and the elastic reset member 14 is positioned near the buckle. This arrangement simplifies the structure, reduces the volume and size of the buckle, and the proximity of the elastic reset member 14 to the buckle shortens the lever arm length, making the buckle easier to open.

[0043] To facilitate the connection and fixation of the mounting base 12, in the technical solution provided in this application embodiment, the mounting base 12 is installed on the box to be connected by screws.

[0044] This application also provides a storage box, including: a storage box body 2, a cover, and a handle 1 of any one of the above. The cover is connected to the storage box body 2 via a pivot 13. In the closed position, the cover and the storage box body 2 are sealed together. The handle 1 is installed on either the cover or the storage box body 2, and is snapped onto the other. The storage box body 2 here is the aforementioned box to be connected. After the handle 1 is connected to the storage box body 2, the storage box can be opened / locked by pulling the handle body 11.

[0045] Please refer to this section for further information. Figure 3 This application also provides a 3D printer, including the aforementioned handle 1 and / or the aforementioned material storage box. The 3D printer containing the aforementioned handle 1 and / or material storage box allows for easy opening / closing of the 3D printer material box by pulling the handle body 11, making operation simple and convenient.

[0046] In summary, this application provides a handle comprising: a handle body and a mounting base, wherein the mounting base is mounted on a box to be connected, or the mounting base and the box to be connected are an integral structure, and the handle body and the mounting base are connected by a pivot; a buckle is provided at the base of the handle body, and a through hole is provided on the mounting base, the buckle passing through the through hole and engaging with the box to be connected. This application also provides a storage box comprising a storage box body, a cover plate, and the aforementioned handle, and further provides a 3D printer comprising the aforementioned handle or the aforementioned storage box. In the technical solution provided in this application, the mounting base is moved by pulling the handle, and the mounting base further drives the connected box to be connected to open, thus completing the unlocking; when locking is required, the handle body is reset downwards, and the buckle at the base of the handle body engages with the box to be connected to achieve locking; this handle structure can be matched and installed with the storage box and 3D printer, solving the technical defects of the prior art, which requires the use of multiple structural parts to realize the opening and locking functions of the 3D printer storage box, which is inconvenient to operate and easy to forget.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.
