DETAILED DESCRIPTION

[0021] See also Figure 1-5The utility model provides a control device for a disturbance-free switching rotary film deaerator, comprising a control box 1, a support seat 2 is arranged at the bottom of the control box 1, a moving seat 3 is arranged at the middle position between the control box 1 and the support seat 2, a storage groove 4 is opened at the middle position of the top surface of the moving seat 3, a central shaft 5 is rotatably connected at the middle position of the inner cavity of the storage groove 4, a first gear 6 is fixedly sleeved on the outer circumference of the central shaft 5, racks 7 are meshed at both ends of the first gear 6, a limiting shaft 8 is inserted through the surface of the rack 7, and both sides of the limiting shaft 8 are fixed to the inner cavity surface of the storage groove 4, a first threaded rod 9 is threadedly connected to the surface of one of the racks 7 at the position of the bottom of the limiting shaft 8 at an adjacent position, and one side of the first threaded rod 9 is rotatably connected to the inner cavity surface of the storage groove 4, and the first The other side of the threaded rod 9 passes through the moving seat 3 and extends out of the moving seat 3. Slide plates 10 are arranged on both sides of the top of the storage groove 4, wherein the bottoms of the two slide plates 10 are fixed to the surfaces of the tops of the racks 7 at adjacent positions, and a connecting plate 14 is fixed at the middle positions of the two adjacent slide plates 10. The top of the slide plate 10 is hinged with a support rod 11, and the top of the support rod 11 is hinged to the surface of the bottom of the control box 1. By rotating the first threaded rod 9, the two racks 7 can move in the horizontal direction, so that the angles of the two support rods 11 can be changed, so that the height of the support seat 2 can be changed, so that the user can fine-tune the height position of the control box 1 according to actual use requirements, making the adjustment and installation process of the control box 1 more convenient and labor-saving.

[0022] Further Figure 1 and Figure 4 As shown, it is worth explaining in detail that openings 15 are symmetrically distributed on both sides of the top surface of the control box body 1, and the openings 15 are arranged in a T shape. A sliding seat 17 is slidably inserted at the top of the inner cavity of the opening 15. The top of the sliding seat 17 passes through the adjacent opening 15 and is fixed to the surface of the bottom of the moving seat 3. Since the sliding seat 17 is subject to the resistance and limitation of the inner cavity of the limit rod 19, the moving seat 3 can slide a certain distance in the front and rear direction under the connection action of the sliding seat 17.

[0023] Further Figure 1 and Figure 4As shown, it is worth explaining in detail that a second threaded rod 16 is threadedly connected through the middle position of the two sliding seats 17, one end of the second threaded rod 16 passes through the control box 1 and extends to one end position of the control box 1, and the other end of the second threaded rod 16 is rotatably connected to the inner cavity surface of the opening 15 at the adjacent position, and a limiting rod 19 is inserted through the middle position of the other two sliding seats 17, and the two ends of the limiting rod 19 are fixed to the inner cavity surface of the opening 15 at the adjacent position. By rotating the second threaded rod 16, the two sliding seats 17 adjacent to the second threaded rod 16 are resisted by the opening 15, so that the sliding seat 17 can move in the horizontal direction under the cooperation between the internal thread structure of its inner wall and the external thread structure of the outer peripheral surface of the second threaded rod 16, thereby driving the moving seat 3 to move, and due to the connection relationship between the other group of sliding seats 17 and the moving seat 3 and the fact that it can only slide along the outer peripheral surface of the limiting rod 19, it can limit the movement trajectory of the moving seat 3 and make it move smoothly.

[0024] Further as Figure 5 As shown, it is worth explaining in detail that a plurality of tooth blocks 21 are evenly fixed on one side of the bottom of the inner cavity surface of the limit rod 19, the surface of the bottom of the sliding seat 17 is rotatably connected to the rotating shaft 20, and the outer circumferential surface of the rotating shaft 20 is fixedly sleeved with a second gear 18, and the second gear 18 is meshed with a group of tooth blocks 21 at adjacent positions. When the sliding seat 17 slides with the inner cavity of the opening 15 at the adjacent position, the second gear 18 is resisted by the tooth block 21 to drive the rotating shaft 20 to rotate, so that the motion trajectory of the sliding seat 17 can be further limited under the meshing action between the second gear 18 and a group of tooth blocks 21 at the adjacent position.

[0025] This scheme has the following working process: in actual use, when the user needs to adjust the height of the control box 1 due to usage conditions, by rotating the first threaded rod 9, the rack 7 is limited by the limiting shaft 8, so that one of the racks 7 can move in the horizontal direction under the cooperation between the internal thread structure of its inner wall and the external thread structure of the outer peripheral surface of the first threaded rod 9, so that it will mesh with the first gear 6 to enable the central shaft 5 to rotate, so that the rack 7 can move in the horizontal direction and its movement direction is opposite under the meshing action between the central shaft 5 and the other rack 7, so that the two racks 7 can slide synchronously, so that the multiple slides 10 can slide synchronously under the connection action of the connecting plate 14, Thereby, the angle of the support rod 11 can be changed, so that the height of the support seat 2 can be rotated. When the position of the control box 1 along the front-to-back direction needs to be adjusted due to usage conditions, the second threaded rod 16 is rotated. Since the two sliding seats 17 adjacent to the second threaded rod 16 are resisted by the opening 15, the sliding seat 17 can move in the horizontal direction under the cooperation between the internal thread structure of its inner wall and the external thread structure of the outer peripheral surface of the second threaded rod 16, thereby driving the moving seat 3 to move. Due to the connection relationship between the other group of sliding seats 17 and the moving seat 3 and the fact that it can only slide along the outer peripheral surface of the limit rod 19, the movement trajectory of the moving seat 3 can be limited to make its movement smooth, so that the sliding seat 17 can drive the moving seat 3 to make horizontal movement along the front-to-back direction.

[0026] According to the above working process, it can be known that: by rotating the first threaded rod 9, the two racks 7 can move in the horizontal direction, so that the angles of the two support rods 11 can be changed, so that the height of the support seat 2 can be changed, so that it is convenient for the user to fine-tune the height position of the control box 1 according to actual use requirements, making the adjustment and installation process of the control box 1 more convenient and labor-saving, thereby improving the convenience of use of the device, and by rotating the second threaded rod 16, the sliding seat 17 can move in the horizontal direction and cooperate with the limit rod 19, the second gear 18 and the tooth block 21 to limit the movement of the moving seat 3, so that the moving seat 3 can drive the control box 1 to move in the horizontal direction, thereby realizing the forward and backward movement of the entire control box, making it more labor-saving to move the entire control box, thereby further improving the convenience of use of the device.

[0027] Further Figure 2As shown, it is worth explaining in detail that fixed blocks 12 are fixed at the four corners of the top surface of the moving seat 3, and a connecting shaft 13 is fixed at the middle position of two adjacent fixed blocks 12. The connecting shaft 13 and the two adjacent slides 10 are slidably connected. Due to the setting of the fixed blocks 12 and the connecting shaft 13, the slide 10 can be supported by the connecting shaft 13, thereby making the stability of the control box 1 better.

[0028] In summary: by rotating the first threaded rod 9, the two racks 7 can move in the horizontal direction, so that the angles of the two support rods 11 can be changed, and thus the height of the support seat 2 can be changed, so that it is convenient for the user to fine-tune the height position of the control box 1 according to actual use requirements, making the adjustment and installation process of the control box 1 more convenient and labor-saving, thereby improving the convenience of use of the device, and by rotating the second threaded rod 16, the sliding seat 17 can move in the horizontal direction and cooperate with the limit rod 19, the second gear 18 and the tooth block 21 to limit the movement of the moving seat 3, so that the moving seat 3 can drive the control box 1 to move in the horizontal direction, thereby realizing the forward and backward movement of the entire control box, making it more labor-saving to move the entire control box, thereby further improving the convenience of use of the device, and due to the setting of the fixed block 12 and the connecting shaft 13, the connecting shaft 13 can support the skateboard 10, so that the stability of the control box 1 is better.
