The inner surface of the other mounting base 8 is rotatably connected to a sliding rod 13 via a rotating shaft. The outer surface of the sliding rod 13 is slidably connected to the inner surface of the sliding shell 9.
[0040] A support component is provided inside the sliding shell 9 to support and limit the sliding rod 13.
[0041] In a specific embodiment of this utility model, the electrophoresis drying oven body 1 serves as the main support structure of the drying oven, bearing all door components and the internal working space. The door body 2 opens and closes via a hinge, sealing or opening the working chamber of the drying oven. A storage groove 4 is formed on the side wall of the oven body to store the limiting block 7 and its connecting parts, preventing interference with the door's movement. A limiting groove 3 is formed on the edge of the door body, providing a linear sliding track for the limiting block 7 and constraining the opening and closing angle of the door. The limiting block 7 slides within the limiting groove 3, converting the relative displacement between the door and the oven body into linear motion. One end of the mounting base 8 is fixed to the limiting block 7, and the other end is fixed to the inner wall of the storage groove 4. It also serves as the rotation fulcrum for the sliding shell 9 and the sliding rod 13. The sliding shell 9 is connected to the mounting base 8 via a rotating shaft, forming a rotatable outer shell. The sliding rod 13 provides a sliding channel. One end of the sliding rod 13 is connected to another mounting base 8 via a pivot and slides inside the sliding shell 9, converting the rotational motion of the door opening and closing into a telescopic motion.

The extrusion plate 12 is slidably connected to the inner wall of the sliding shell 9 and is also fixedly connected to the end of the sliding rod 13. As it moves, it pushes the first spring 11. The first spring 11 is sleeved on the outside of the support base 10 and generates a damping force when compressed by the extrusion plate 12, buffering the impact of the sliding rod 13. It should be noted that the specific model of the electrophoretic drying oven body 1 used shall be selected by those skilled in the art, and the above-mentioned electrophoretic drying oven body 1, etc., are all existing technologies, and this solution will not elaborate further.

[0045] Please refer to the details. Figure 4 The electrophoretic drying oven body 1 has multiple mounting slots 21 at one end, and the inner surface of each mounting slot 21 is provided with a sealing gasket 5.
[0046] In this embodiment: the mounting groove 21 is opened on the edge of the box door frame to fix the sealing gasket 5. The sealing gasket 5 is embedded in the mounting groove 21 and presses the gap of the door frame when the door is closed to ensure the sealing of the box.
[0047] Please refer to the details. Figure 4 It also includes multiple sets of buffer mechanisms, each set of which includes:
[0048] The sliding groove 14 is opened at one end of the body 1 of the electrophoresis drying oven. The inner surface of the sliding groove 14 is slidably connected to the extrusion seat 18. One end of the extrusion seat 18 is fixedly connected to the buffer rod 19. The outer surface of the buffer rod 19 is fixedly connected to the buffer pad 20.
[0049] An elastic component is provided within the sliding groove 14 to limit the movement of the sliding buffer rod 19.
[0050] In this embodiment: the sliding groove 14 is opened in the door frame of the box body to provide a linear sliding track for the compression seat 18. The compression seat 18 slides in the sliding groove 14 to transmit the impact force of the door body to the elastic component. The buffer rod 19 is fixedly connected to the compression seat 18, extends outward and carries the buffer pad 20. The buffer pad 20 is made of elastic material such as rubber, directly contacts the door body and absorbs the collision energy. The limiting seat 15 is fixed to the inner wall of the sliding groove 14 as a static mounting base for the second spring 17. The limiting rod 16 slides on the inner wall of the limiting seat 15 and is fixed with the compression seat 18 to push the second spring 17 to compress. Since the second spring 17 is sleeved on the outside of the limiting seat 15, it generates buffer resistance when the limiting rod 16 is compressed.
[0051] Please refer to the diagram for details. Each set of elastic components includes:
[0052] The limiting seat 15 is fixedly connected to the inner surface of the sliding groove 14. The inner surface of the limiting seat 15 is slidably connected to the limiting rod 16. One end of the limiting rod 16 is fixedly connected to one end of the pressing seat 18. The outer surface of the limiting seat 15 is fitted with a second spring 17.
[0053] In this embodiment: the limiting seat 15 is fixed to the inner wall of the sliding groove 14 as a static mounting base for the second spring 17. The limiting rod 16 slides on the inner wall of the limiting seat 15 and is fixed with the compression seat 18, pushing the second spring 17 to compress. Since the second spring 17 is sleeved on the outside of the limiting seat 15, it generates buffer resistance when the limiting rod 16 is compressed.
[0054] Please refer to the details. Figure 3 and Figure 4 Multiple buffer grooves 6 are provided at one end of the door body 2, and the inner surfaces of the multiple buffer grooves 6 and the outer surfaces of the multiple buffer pads 20 are slidably connected.
[0055] In this embodiment: the buffer groove 6 is opened on the edge of the door, corresponding to the position of the buffer pad 20; when closed, it accommodates the buffer pad 20 and guides precise positioning. When the buffer pad 20 is embedded in the buffer groove 6, the impact force is dispersed by sliding friction to avoid hard contact between the door and the cabinet, thereby reducing noise and wear.
[0056] The working principle and usage process of this utility model are as follows: The door body 2 rotates outward around the hinge axis on the side wall of the electrophoresis drying oven body 1. The limiting block 7 slides inward along the limiting groove 3 on the door body 2. The sliding rod 13 extends outward from the sliding shell 9. The pressing plate 12 moves with the sliding rod 13 and stretches the first spring 11. When the sliding rod 13 is fully extended out of the sliding shell 9, the limiting block 7 abuts against the end of the limiting groove 3, limiting the maximum opening angle of the door. When the door body 2 rotates and closes around the hinge axis, the door body 2 rotates towards the door frame of the electrophoresis drying oven body 1. The limiting block 7 slides inward along the limiting groove 3. The groove 3 slides outward, the sliding rod 13 retracts into the sliding shell 9, the squeezing plate 12 compresses the first spring 11 to generate damping force, and slows down the closing speed. When the door is close to closing, the buffer groove 6 on the door body 2 aligns with the buffer pad 20, the buffer pad 20 is embedded in the buffer groove 6, the buffer pad 20 is squeezed by the buffer groove 6, and pushes the buffer rod 19 to move into the sliding groove 14. The buffer rod 19 drives the squeezing seat 18 to compress the second spring 17, the limiting rod 16 slides along the limiting seat 15 to constrain the buffer stroke, and the compression force of the second spring 17 is converted into damping to absorb the impact energy of the door.
