[0015] Figure 2 is the side view structural schematic diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the drawings and the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] Refer to Figure 1 and Figure 2, the present utility model provides a downward sealing docking device, which is arranged at the lower port of the upper container and is used for sealingly docking the upper container and the lower container. It includes a fixing frame 1, an airbag 2, a lifting plate 3 and a docking flange 4. There are two fixing frames 1 and two airbags 2. The two fixing frames 1 are fixedly connected to both sides of the lower opening of the upper container. The airbag 2 is provided with an air charging and discharging port. The upper ends of the two airbags 2 are respectively fixedly connected to the lower surfaces of the two fixing frames 1. The two ends of the lifting plate 3 are respectively fixedly connected to the lower ends of the two airbags 2. A docking ring 5 is fixedly arranged in the middle of the lifting plate 3. The docking flange 4 is connected to the docking ring 5 with adjustable position. The outer diameter of the lower end of the docking flange 4 is larger than the outer diameter of the docking ring 5. The upper end of the docking flange 4 is softly connected to the lower opening of the upper container;

[0018] On the front and back sides of each of the fixing frames 1, a "7"-shaped upper hanging plate 8 is respectively fixedly arranged. A bolt 13 with adjustable position is arranged on the horizontal section of the upper hanging plate 8. On the front and back sides of the two ends of the lifting plate 3, at positions corresponding to the bolt 13 up and down, a lower hanging plate 9 is respectively arranged. A spring 10 is connected between the lower end of the bolt 13 on the same side and the lower hanging plate 9.

[0019] In this embodiment, the downward sealing docking device provided by the present utility model is used for transporting granular or powdery materials between the upper container and the lower container. This device is connected to the lower port of the upper container through a hose or a cloth bag. When docking is required, the airbag 2 is inflated through the air charging and discharging port. The airbags 2 on both sides extend downward, thereby overcoming the pulling force of the spring 10 and pushing the lifting plate 3 to descend. The lifting plate 3 drives the docking flange 5 to descend through the support ring 4. The lower end of the docking flange 5 completes the sealing docking with the upper port of the lower container. At this time, the material can be transported. When the transportation is completed, the airbag 2 is deflated through the air charging and discharging port. The airbag 2 retracts. Under the pulling force of the spring 10, it drives the lifting plate 3 to rise. The lifting plate 3 drives the docking flange 5 to rise through the support ring 4. The upper port of the lower container is separated from the docking flange 5. The pulling force of the spring 10 can be adjusted through the bolt 13.

[0020] In order to enable the lifting plate 3 to rise or descend stably and to limit the maximum descending height of the lifting plate 3, as an improvement of the technical solution, on the fixing frames 1 on the front and back sides of the airbag 2, a guiding column 6 is respectively arranged. The two ends of the lifting plate 3 are respectively movably sleeved on the guiding columns 6 on both sides. The lower ends of the two guiding columns 6 on the same side are both fixedly connected to a limiting plate 7.

[0021] Preferably, the guiding column 6 is divided into three sections. The diameter of the upper section of the three-section guiding column 6 is the largest, and the diameter of the lower section is the smallest. The lifting plate 3 is movably sleeved on the middle section of the guiding column 6. The limiting plate 7 is fixedly connected to the upper end of the lower section of the guiding column 6.

[0022] In order to adjust the distance between the docking flange 4 and the docking ring 5 so as to adapt to the distances between different container ports, as an improvement of the technical solution, a number of adjusting screws 11 are fixedly provided on the upper surface of the docking flange 4, and through holes of the same number are provided on the lifting plate 3. Each adjusting screw 11 passes through one through hole and is fixed in position by nuts on both sides of the through hole.

[0023] In order to further enhance the sealing, a sealing ring 12 is provided at the lower end of the docking flange 4.

[0024] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
