DETAILED DESCRIPTION

[0020] See also Figure 1-6 The utility model provides an inner opening fan profile with a double sealing structure, including an upper abdominal cavity 1, a lower abdominal cavity 2 is arranged on one side of the upper abdominal cavity 1, a connecting cavity 3 is arranged at the middle position between the upper abdominal cavity 1 and the lower abdominal cavity 2, and L-shaped positioning strips 6 are arranged at the four corners of the inner cavity of the connecting cavity 3, and a heat insulation strip 5 is inserted inside the four positioning strips 6, one side of one group of positioning strips 6 is fixed to the surface of the upper abdominal cavity 1, and one side of another group of positioning strips 6 is fixed to the surface of the lower abdominal cavity 2, and sealing plates 4 are arranged at the two ends of the inner cavity of the connecting cavity 3, and two symmetrically distributed positioning blocks 16 are fixed on the surface of one end of the sealing plate 4, and the two adjacent positioning blocks 16 are close to each other. One end of the connecting rod 11 is rotatably connected to a threaded rod 11, and the outer circumferential surface of the threaded rod 11 is threadedly connected to a threaded sleeve 14 arranged in a T shape, and an insertion rod 15 is fixed to one end of the threaded sleeve 14. The two ends of the inner cavity surface of the connecting chamber 3 are connected to two symmetrically distributed slots 9, and one end of the insertion rod 15 extends to the inside of the adjacent slot 9. When a heat insulation strip 5 is provided inside the connecting chamber 3, by placing the sealing plate 4 at the two end positions of the inner cavity of the connecting chamber 3, and by rotating the rotating rod 10, the two insertion rods 15 can be embedded in the inside of the adjacent slots 9, so that the sealing plate 4 can be fixed at the two end positions of the inner cavity of the connecting chamber 3, so as to play a sealing role from the two end positions of the connecting chamber 3.

[0021] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth explaining in detail that a rotating rod 10 is rotatably connected through the middle position of the sealing plate 4, and a first bevel gear 12 is fixedly sleeved on the outer circumference of the rotating rod 10. A second bevel gear 13 is rotatably connected to the outer circumference of the threaded rod 11 near the first bevel gear 12 at an adjacent position. The first bevel gear 12 is meshingly connected to the two adjacent second bevel gears 13. By rotating the rotating rod 10, the first bevel gear 12 can be in a rotating state, so that the two threaded rods 11 can rotate synchronously under the meshing action between the first bevel gear 12 and the two adjacent second bevel gears 13.

[0022] Further as Figure 3As shown, it is worth explaining in detail that a limiting groove 17 is provided on the surface of the sealing plate 4 at the middle position of the two adjacent positioning blocks 16, and a limiting block 18 is slidably inserted inside the limiting groove 17. One end of the limiting block 18 passes through the adjacent limiting groove 17 and is fixed to the surface of the adjacent threaded sleeve 14. Since the limiting block 18 can only slide in the vertical direction at the inner cavity position of the limiting groove 17, it can limit the movement trajectory of the threaded sleeve 14, so that it can only move in the vertical direction.

[0023] Further as Figure 3 As shown, it is worth explaining in detail that two trapezoidal connecting grooves 7 are opened at the inner surface of the upper abdominal cavity 1 near the lower abdominal cavity 2, and a trapezoidal connecting strip 8 is inserted inside the connecting groove 7. The surface of the connecting strip 8 near the lower abdominal cavity 2 is fixed to the surface of the lower abdominal cavity 2, and the connecting strip 8 is extended to the inside of the connecting groove 7 at the adjacent position when the upper abdominal cavity 1 is connected with the lower abdominal cavity 2. Under the shape setting of the connecting groove 7 and the connecting strip 8, the distance between the two can be prevented from changing due to the interference between the surface of the connecting strip 8 and the inner cavity of the connecting groove 7.

[0024] This solution has the following working process: in actual use, when the user extends the connecting strip 8 to the inside of the connecting groove 7 at the adjacent position, thereby connecting the upper abdominal cavity 1 with the lower abdominal cavity 2, and inserts the heat insulation strip 5 in the middle position of the four positioning strips 6, and then places the sealing plate 4 at the two end positions of the inner cavity of the connecting cavity 3, the first bevel gear 12 can be in a rotating state by rotating the rotating rod 10, so that the two threaded rods 11 can rotate synchronously under the meshing action between the first bevel gear 12 and the two adjacent second bevel gears 13, because the limit block 18 can only slide in the vertical direction at the inner cavity position of the limit groove 17 The threaded sleeve 14 can move in a restricted manner so as to limit the movement trajectory of the threaded sleeve 14, so that it can only move in the vertical direction. As a result, the internal thread structure on the inner wall of the threaded sleeve 14 and the external thread structure at the corresponding position of the outer circumferential surface of the threaded rod 11 can cooperate to make the threaded sleeves 14 at two adjacent positions move away from each other, so that the insertion rod 15 can be embedded in the interior of the adjacent position slot 9, so that the sealing plate 4 can be fixed to the two ends of the inner cavity of the connecting cavity 3 through the interference between the insertion rod 15 and the slot 9, so as to seal the connecting cavity 3, thereby avoiding the influence of the external environment, and effectively maintaining the service life of the thermal insulation strip 5.

[0025] According to the above working process, it can be known that: when a heat insulation strip 5 is provided inside the connecting chamber 3, by placing the sealing plate 4 at the two end positions of the inner cavity of the connecting chamber 3, and by rotating the rotating rod 10 so that the two insertion rods 15 can be embedded in the adjacent position slots 9, the sealing plate 4 can be fixed at the two end positions of the inner cavity of the connecting chamber 3, so that a sealing effect can be played from the two end positions of the connecting chamber 3, thereby avoiding the influence of the external environment, thereby effectively maintaining the service life of the heat insulation strip 5, and improving the practicality of the device.

[0026] Further as Figure 4 As shown, it is worth explaining in detail that the inner cavity of the limit groove 17 is T-shaped, and the surface of the limit block 18 located in the inner part of the limit groove 17 at the adjacent position is T-shaped. Due to the shape of the inner cavity surface of the limit groove 17 and the limit block 18, the limit block 18 can be prevented from detaching from the inside of the limit groove 17 at the adjacent position due to the interference between the surface of the limit block 18 and the inner cavity surface of the limit groove 17.

[0027] In summary: when a thermal insulation strip 5 is provided inside the connecting chamber 3, the sealing plate 4 is placed at the two end positions of the inner cavity of the connecting chamber 3, and the two insertion rods 15 are embedded in the adjacent position slots 9 by rotating the rotating rod 10, so that the sealing plate 4 can be fixed at the two end positions of the inner cavity of the connecting chamber 3, so that it can play a sealing role from the two end positions of the connecting chamber 3, thereby avoiding the influence of the external environment, thereby effectively maintaining the service life of the thermal insulation strip 5, thereby improving the practicality of the device, and due to the shape setting of the inner cavity surface of the limit groove 17 and the limit block 18, the limit block 18 can be prevented from detaching from the inside of the adjacent limit groove 17 under the interference between the surface of the limit block 18 and the inner cavity surface of the limit groove 17.
