Detailed Implementation
[0018] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:
[0019] Example 1
[0020] refer to Figures 1 to 2Example 1 illustrates the following: A frame 13 is located at the bottom of the entire device. A movable door 18 is installed on the front of the frame 13. An expansion body 17 is installed at the top of the frame 13. A linkage mechanism is installed inside the expansion body 17, and a spindle 4 is installed on one side of the linkage mechanism. A positioning sleeve 3 for positioning is installed on the spindle 4. A mounting base 9 is connected to the bottom of the spindle 4. A guide rod 10 is installed at the bottom of the mounting base 9. A fixed support 11 is provided at the bottom of the guide rod 10. A cylinder 12 is installed at the bottom of the fixed support 11. An opening 14 is provided on the frame 13, and the diameter of the opening 14 is larger than the diameter of the guide rod 10. A capsule skin 2 is provided on the surface of the expansion body 17. A silicone sleeve 1 made of silicone is fitted on the outer layer of the capsule skin 2. The movable door 18 is hinged to the frame 13 by a hinge 19. A handle 20 for controllable switching is fixedly installed on the front of the movable door 18.
[0021] In this embodiment, the movable door 18 can be easily opened to conduct regular inspections and cleaning of the interior, ensuring its continued service life.
[0022] Example 2
[0023] refer to Figure 3 Example 2 is described below. This embodiment further describes Example 1 and includes a linkage mechanism. A first outer folding plate 5 is installed on the linkage mechanism. The bottom end of the first outer folding plate 5 is rotatably connected to a second outer folding plate 7 via a rotating shaft 16. A long connecting rod 6 is rotatably connected to the second outer folding plate 7 via a rotating shaft 16. The long connecting rod 6 is rotatably connected to a connecting block 15 via a rotating shaft 16, and the connecting block 15 is fixedly installed on a sliding sleeve 8.
[0024] In this embodiment, the linkage mechanism can drive the first outer folding plate 5 and the second outer folding plate 7 to move outward simultaneously and expand into a set shape. The straight bladder skin expands into the set shape synchronously, thereby expanding the bladder skin that needs to be expanded.
[0025] In practical applications, this device drives the sliding sleeve 8 to move upward along the spindle 4 via the cylinder 12. Since the four corners of the sliding sleeve 8 are fixedly connected with connecting blocks 15, and the connecting blocks 15 connected around the perimeter are rotatably connected to the long connecting rod 6 via the rotating shaft 16, and the other side of the long connecting rod 6 is rotatably connected to the second outer folding plate 7 via the rotating shaft 16, the linkage mechanism drives the first outer folding plate 5 and the second outer folding plate 7 to move outward simultaneously, expanding into a set shape. The straight cylinder skin expands synchronously into the set shape, thereby expanding the skin that needs to be expanded. This allows the expansion device to complete the expansion of the skin simply and quickly, reducing the difficulty of manually putting on the skin, improving efficiency, maintaining the uniformity of the skin, and improving the vulcanization quality of the air spring skin.
