[0029] like Figures 1-3 As shown, the utility model proposes a door handle anodizing device, including an oxidation tank 1, a mixing component, a driving mechanism and a placement component. Mixing components are provided at both ends of the oxidation tank 1, and a driving mechanism for driving the two groups of mixing components to run synchronously is provided above the mixing component. The placement component is arranged between the two groups of mixing components, and a lifting component 2 is provided on the placement component for driving it to move vertically in the oxidation tank 1.

[0030] like Figure 3 As shown, the mixing component includes a bending plate 3, a rotating shaft 4 and mixing blades 5. The bending plate 3 is symmetrically arranged at both ends of the top of the oxidation tank 1. A rotating shaft 4 is rotatably arranged between the bending plate 3 and the bottom of the oxidation tank 1. A plurality of groups of mixing blades 5 are evenly arranged on the rotating shaft 4 in a circle.

[0031] like Figure 3 As shown, the driving mechanism includes a driving motor 6, a pulley 7 and a belt 8. There are two groups of pulleys 7, which are respectively installed on the rotating shaft 4. A belt 8 is arranged for transmission between the two groups of pulleys 7. The driving motor 6 is installed on one group of bending plates 3, and its output end is connected to the corresponding rotating shaft 4. Through the pulley 7 and the belt 8, the two groups of rotating shafts 4 can rotate synchronously when rotating.

[0032] like Figure 1 and Figure 2 As shown, the top of one side of the oxidation pond 1 is connected to a liquid inlet pipe 15, and the bottom of the other side is connected to a liquid outlet pipe 16. A valve is provided on the liquid outlet pipe 16, and a connecting flange is provided at the end of the liquid inlet pipe 15. The electrolyte is introduced through the liquid inlet pipe 15 and discharged through the liquid outlet pipe 16.

[0033] Embodiment 2

[0034] like Figures 1-3 As shown, the present invention proposes a door handle anodizing device. Based on the above embodiment, this embodiment records in detail the specific components of the placement assembly and the connection method thereof with the oxidation tank 1.

[0035] As Figure 2 and Figure 3 shown, the placing component includes a bending frame 9, a cover plate 10, a connecting shaft 12 and a placing frame 14. The cross-section of the bending frame 9 is set as an L-shaped structure. One end of its horizontal section is connected to the lifting member 2. The lifting member 2 is a hydraulic cylinder, which is installed on the side wall of the oxidation tank 1, and its output end is connected to the bending frame 9. The cover plate 10 is arranged at the bottom end of the vertical section of the bending frame 9, and perforations 11 are opened at its four corners. Connecting shafts 12 are inserted into the four groups of perforations 11. A placing frame 14 is connected to the bottom ends between the four connecting shafts 12, and an anti-detachment plate 13 is connected to the top ends of the four connecting shafts 12.

[0036] Among them, the cover plate 10 moves up and down within a certain range under the action of the lifting member 2. During the moving interval, it is always located below the belt 8 and does not interfere with the operation of the belt 8.

[0037] As Figure 1 shown, a plurality of uniformly distributed water passing holes are opened on both the placing frame 14 and the cover plate 10.

[0038] In summary, when the present utility model is in use, the door handle to be oxidized is placed into the placing frame 14 through the gap between the placing frame 14 and the cover plate 10. Then, the lifting member 2 is used to drive the bending frame 9 to descend, so that the bending frame 9 drives the placing frame 14 to descend synchronously through the cover plate 10. When the placing frame 14 contacts the bottom of the tank, with the continuous operation of the lifting member 2, the cover plate 10 is driven to move relative to the placing frame 14 until the cover plate 10 closes the placing frame 14. Then, the driving motor 6 is started. The driving motor 6 drives the two groups of rotating shafts 4 to rotate through the cooperation of the belt pulley 7 and the belt 8, so that the mixing blades 5 mix the electrolyte. During the mixing process, the concentration of the electrolyte is made uniform, and the oxidation effect on the surface of the door handle is relatively uniform. After the mixing is completed, the lifting member 2 drives the cover plate 10 to move upward relative to the placing frame 14, so as to open the placing frame 14. With the continuous operation of the lifting member 2, the placing frame 14 and the door handle inside are integrally lifted upward, which is convenient for taking out the oxidized door handle.

[0039] The above has described in detail the embodiments of the present utility model in conjunction with the accompanying drawings. However, the present utility model is not limited thereto. Various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art to which the present utility model pertains.
