[0022] Example 1

[0023] like Figs. 1 to 3 As shown, this utility model provides a hydraulic power device for an ultra-thin, noiseless lifting platform, including a connecting and stabilizing plate 1. The lower end of the connecting and stabilizing plate 1 is fixedly connected to a lifting rod 2. The upper outer side of the lifting rod 2 is connected to a reinforcing seat 3 by a bearing. The reinforcing seat 3 is located at the lower end of the connecting and stabilizing plate 1, and a main gear 4 is provided at the lower end of the reinforcing seat 3. The lifting rod 2 is connected to the lifting rod 2 by a bearing at the center of the main gear 4, and a vertical gear 5 is meshed with the right side of the main gear 4. The lower end of the vertical gear 5 is connected to a meshing transmission mechanism 6, and a motor 7 is connected to the lower end of the meshing transmission mechanism 6. The lower end of the lifting rod 2 is connected to a hydraulic lift 8.

[0024] Furthermore, the center positions of the pinion 63 and the second gear 64 are both movably connected to the lifting rod 2, and the center positions of the vertical gear 5, the first gear 62, the second pinion 65, and the third gear 66 are all fixedly connected to the transmission shaft 61. During the lifting process, the lifting rod 2 will not drive the pinion 63 and the second gear 64 to lift or lower. During the rotation of the transmission shaft 61, the vertical gear 5, the first gear 62, the second pinion 65, and the third gear 66 will rotate. The position setting of the pinion 63 and the second gear 64 can reduce the volume of the entire hydraulic power device and occupy a smaller area.

[0025] Furthermore, the meshing transmission mechanism 6 includes a transmission shaft 61, which is located at the center of the vertical gear 5. A first gear 62 is fixedly connected to the outer side of the lower end of the transmission shaft 61. A pinion 63 is meshed with the left side of the first gear 62. A lifting rod 2 is movably connected to the center of the pinion 63. A second gear 64 is located at the lower end of the pinion 63. A second pinion 65 is meshed with the right side of the second gear 64. A third gear 66 is located at the lower end of the second pinion 65. A movable main gear 67 is meshed with the right side of the third gear 66. The movable main gear 67 is fixedly connected to the output shaft 68 at its center. The lower end of the output shaft 68 is connected to the motor 7. When the motor 7 starts working, its rotation drives the output shaft 68 to rotate, which in turn drives the movable main gear 67 to rotate. The movable main gear 67 drives the third gear 66 to rotate, which in turn drives the transmission shaft 61 to rotate. The transmission shaft 61 drives the vertical gear 5 to rotate, which in turn drives the main gear 4 to rotate, thus driving the entire connecting and stabilizing plate 1 to rotate. This enables the external platform on the upper end of the connecting and stabilizing plate 1 to rotate, providing multiple functions.

[0026] Furthermore, a turntable 41 is provided on the lower end face of the main gear 4. The upper end of the turntable 41 is movably connected to the main gear 4, and the lower end of the center position of the turntable 41 is fixedly connected to the lifting rod 2. The turntable 41 and the lifting rod 2 are fixedly connected. In this way, when the hydraulic lift 8 is working, it will drive the lifting rod 2 to rise, thereby causing the main gear 4 to rise, so that the entire connecting and stabilizing plate 1 can be hydraulically raised, which is simple and efficient.

[0027] Furthermore, a convex protective cover 9 is provided on the outer side of the meshing transmission mechanism 6, and a rectangular protective cover 10 is provided on the outer side of the hydraulic lift 8 and the motor 7. A dustproof plate 91 is provided on the upper end of the main gear 4. The lifting rod 2 is connected to the center of the dustproof plate 91 by a bearing. A protective chamber 92 is provided on the outer side of the main gear 4. The convex protective cover 9 is fixedly connected to the lower end of the protective chamber 92, and a ring of sound-absorbing cotton is provided inside the protective chamber 92. The dustproof plate 91 is set on the upper end of the main gear 4 to prevent dust from entering the protective chamber 92. The sound-absorbing cotton is provided inside the protective chamber 92. The protective chamber 92 covers the entire main gear 4, so that the meshing transmission between the main gear 4 and the vertical gear 5 can be silently wrapped, achieving noiseless rotation. The dustproof plate 91 and the protective chamber 92 are movably connected and do not affect the rise of the entire main gear 4, thereby realizing the lifting and lowering of the connecting stabilizing plate 1.

[0028] Furthermore, the connecting and stabilizing plate 1 has connecting holes 11 evenly provided on both the left and right sides of its surface. The connecting holes 11 are provided to facilitate the connection of an external lifting and rotating platform.

[0029] Working process: First, the hydraulic lift 8 is turned on, and the hydraulic lift 8 drives the lifting rod 2 to rise and fall. Then, the upper end of the connecting plate 1 is connected to the external platform, which can drive the external platform to rise and fall. When the main gear 4 descends to the lowest position and meshes with the vertical gear 5, the motor 7 starts to work. The motor 7 drives the output shaft 68 to rotate, and the output shaft 68 drives the transmission shaft 61 to rotate. The transmission shaft 61 drives the vertical gear 5, the first gear 62, the second pinion 65, and the third gear 66 to rotate. Among them, the pinion 63 and the second gear 64 are driven to rotate, thereby realizing the stable rotation of the entire meshing transmission mechanism 6. It is simple and efficient. The entire hydraulic power device can realize both lifting and rotation, and has multiple functions. Then, a convex protective cover 9, a rectangular protective cover 10, and a protective chamber 92 are set. The entire hydraulic power device occupies little space, is noiseless, and can realize both lifting and rotation, and has multiple functions.
