[0023] As Figures 1-4 shown, the present utility model provides a technical solution: an anti-rust treatment device for a differential housing, including a processing box 1 and a collection box 2. A pressure pump 3 is fixed to the inner wall of the collection box 2 to extract and reuse the anti-rust oil in the collection box 2. A delivery pipe 4 is fixed to the side of the pressure pump 3, and a sprayer head 5 is fixed to the end of the delivery pipe 4 away from the pressure pump 3. An oil outlet 6 is fixed to the side of the processing box 1, and a tilt device 7 is provided at the bottom of the processing box 1, which can tilt the processing box 1 to allow the excess anti-rust oil to flow out from the oil outlet 6. A cleaning device 8 is provided in the processing box 1 to clean the inner wall of the processing box 1 when the processing box 1 is lifted.

[0024] The above tilt device 7 includes a support hinge plate 71, a positioning block 72, a gear shaft 73, a handle 74, a belt 75, a belt pulley 76, a threaded rod 77, a first slider 78, and a first hinge rod 79. A support hinge plate 71 is fixed to the bottom surface of the processing box 1, a positioning block 72 is fixed to the upper surface of the collection box 2, a gear shaft 73 passes through the positioning block 72 and rotates at the passing position. A handle 74 is fixed to the end of the gear shaft 73, and the handle 74 can drive the gear shaft 73 to rotate. A belt 75 is engaged with the outer wall of the gear shaft 73, and the gear shaft 73 can drive the belt 75 to rotate. The middle serrations of the belt 75 are engaged with the gear shaft 73, and both ends of the belt 75 are engaged with belt pulleys 76. When the belt 75 rotates, it can drive the belt pulleys 76 at both ends to rotate. A threaded rod 77 is fixed to the side of the belt pulley 76, and when the belt pulleys 76 at both ends rotate, they can drive the threaded rod 77 to rotate. The threaded rod 77 passes through the first slider 78 and is threadedly connected at the passing position. The bottom surface of the first slider 78 fits the upper surface of the collection box 2. When the threaded rod 77 rotates, since the first slider 78 it passes through is restricted from rotating, it slides along the threaded rod 77. The upper surface of the first slider 78 is hinged to the support hinge plate 71, and a first hinge rod 79 is hinged to the upper surface of the collection box 2. One end of the first hinge rod 79 away from the collection box 2 is hinged to the support hinge plate 71. When the first slider 78 slides, the support hinge plate 71 is simultaneously pushed by the first hinge rod 79 and cannot move, so it rotates around its hinge with the first slider 78.

[0025] The above cleaning device 8 includes a second slider 81, a steering rod 82, a second hinge rod 83, a third hinge rod 84, a telescopic rod 85, a spring 86 and a cleaning plate 87. The threaded rod 77 passes through the second slider 81 and is threadedly connected at the passing-through position. The bottom surface of the second slider 81 fits the upper surface of the collection box 2. When the threaded rod 77 rotates, since the second slider 81 it passes through is restricted from rotating, it slides along the threaded rod 77. The upper surface of the second slider 81 is hinged with the steering rod 82. When the second slider 81 slides, it drives the steering rod 82 to move to the right. One end of the steering rod 82 away from the second slider 81 is hinged with the second hinge rod 83. When the second slider 81 slides to the right, it drives the steering rod 82 to move to the right. One end of the second hinge rod 83 away from the steering rod 82 is hinged with the third hinge rod 84. Since the linear distance between the processing box 1 and the second slider 81 becomes longer, the second hinge rod 83 and the third hinge rod 84 are gradually straightened. The hinged part of the second hinge rod 83 and the third hinge rod 84 is simultaneously hinged with the telescopic rod 85. The telescopic rod 85 passes through the side wall of the processing box 1 and slides at the passing-through position. When the second hinge rod 83 and the third hinge rod 84 are gradually straightened, it drives the telescopic rod 85 to slide inward. A spring 86 is fixed to the inner wall of the processing box 1. One end of the spring 86 away from the inner wall of the processing box 1 is fixed with the cleaning plate 87. The bottom surface and both side surfaces of the cleaning plate 87 fit the inner wall of the processing box 1. One end surface of the cleaning plate 87 fits one end of the telescopic rod 85 away from the hinged part. When the telescopic rod 85 slides inward, it pushes the cleaning plate 87 to slide together. The cleaning plate 87 slides and pulls the spring 86. When it descends, the spring 86 pulls the cleaning plate 87 back to its original position.

[0026] Working principle: Rotate the handle 74. The handle 74 drives the gear shaft 73 to rotate. The rotation of the gear shaft 73 drives the belt 75 to rotate. The rotation of the belt 75 drives the pulley 76 to rotate. The rotation of the pulley 76 drives the threaded rod 77 to rotate. When the threaded rod 77 rotates, the first slider 78 starts to slide. The first slider 78 slides to the right, and the support hinge plate 71 rotates counterclockwise around its hinge with the first slider 78, tilting the processing box 1 and causing the antirust oil to flow out.

[0027] When the threaded rod 77 rotates, the second slider 81 starts to slide. The second slider 81 slides to the right, and the steering rod 82 rotates counterclockwise around its hinge with the second slider 81. When the second slider 81 slides to the right, since the linear distance between the processing box 1 and the second slider 81 becomes longer, the second hinge rod 83 and the third hinge rod 84 are gradually straightened, driving the telescopic rod 85 to slide into the processing box 1. The telescopic rod 85 pushes the cleaning plate 87 to slide towards the middle, which can push the antirust oil on both sides to the middle position, facilitating the discharge of the antirust oil. At the same time, the spring 86 is stretched. When the processing box 1 descends, the cleaning plate 87 returns to its original position under the pull of the spring 86.

[0028] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit and concept of the present utility model are all within the protection scope of the present utility model.
