[0022] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0023] Embodiment 1:

[0024] See also Figure 1-4 The utility model provides a connecting base for a ship gearbox, comprising a base body 1 and a cover 2 installed on the base body 1, wherein a circle of sealing grooves 11 are provided on a side of the base body 1 in contact with the cover 2, and a connecting strip 21 matching the sealing groove 11 is installed on the end of the cover 2 in contact with the base body 1, wherein the connecting strip 21 is inserted into the sealing groove 11, and a groove is provided in the connecting strip 21, and a circle of airbag tubes 22 are installed in the groove, and the airbag tubes 22 are expanded to be in close contact with the inner wall of the sealing groove 11, so as to achieve sealing of the connection between the base body 1 and the cover 2, and a rubber strip 23 is installed on the outer wall of the airbag tube 22, and the airbag tube 22 and the rubber strip 23 are in contact with the inner wall of the sealing groove 11, and the airbag tube 22 expands and squeezes the rubber strip 23, and the connection is multiple-sealed under the contact between the rubber strip 23 and the inner wall of the sealing groove 11.

[0025] Please pay attention to Figure 3-4 The cross-sectional shape of the rubber strip 23 is U-shaped, and the opening of the rubber strip 23 faces the sealing groove 11. The airbag tube 22 is placed in the rubber strip 23. The two ends of the opening of the rubber strip 23 are in contact with the inner wall of the sealing groove 11. The airbag tube 22 expands and squeezes the two ends of the rubber strip 23, so that the two ends of the opening of the rubber strip 23 are simultaneously tightly attached to the inner wall opposite to the sealing groove 11, thereby sealing the connection between the base body 1 and the cover 2. When the airbag tube 22 is tightly attached to the inner wall of the sealing groove 11, triple sealing is achieved at the connection, and the sealing effect is good.

[0026] Please pay attention to Figure 3-4The inner walls of the two ends of the opening of the rubber strip 23 are provided with inward curvatures. Through this design, the rubber strip 23 can better wrap the airbag tube 22, thereby fixing the airbag tube 22. At the same time, the thickness of the two ends of the opening of the rubber strip 23 is thickened, so that when the airbag tube 22 squeezes the rubber strip 23, the rubber strip 23 is in closer contact with the inner wall of the sealing groove 11, thereby ensuring the sealing effect of the rubber strip 23.

[0027] Please pay attention to Figure 1-2 A charging port 24 is installed at the upper end of the cover 2, and the airbag tube 22 is connected to the charging port 24 through a catheter. A one-way valve 221 is also installed between the airbag tube 22 and the charging port 24. It is convenient to inflate the airbag tube 22 through the charging port 24. The one-way valve 221 prevents gas leakage in the airbag tube 22. A sealing cap 241 is installed outside the charging port 24, and the sealing cap 241 is connected to the charging port 24 through a thread. The sealing cap 241 protects the charging port 24, and a sealing ring gasket 242 is also installed between the sealing cap 241 and the charging port 24. The sealing ring gasket 242 also seals the charging port 24. If the airbag tube 22 is damaged and gas leaks, gas leakage from the charging port 24 can be prevented.

[0028] Please pay attention to Figure 4 The sealing groove 11 is in a T-shape, and the width of the connecting strip 21 is consistent with the width of the inner wall of the outer side of the sealing groove 11. This design ensures that the installation position between the base body 1 and the cover 2 is accurate, avoids position misalignment affecting the installation, and ensures that the airbag tube 22 and the rubber strip 23 are in close contact with the inner wall of the sealing groove 11.

[0029] Please pay attention to Figure 1-2 The edges of the base body 1 and the cover 2 are both provided with a plurality of mounting holes 12, and the mounting holes 12 are connected with mounting bolts 25, and the mounting bolts 25 penetrate through the cover 2 and are threadedly connected to the mounting holes 12. The cover 2 is tightly mounted on the base body 1 through the mounting bolts 25, ensuring close contact between the airbag tube 22 and the rubber strip 23 and the sealing groove 11, and avoiding loose installation that affects the sealing performance.

[0030] The working principle of the first embodiment of the utility model is as follows:

[0031] The edge of the cover 2 is tightly mounted on the base body 1 by installing the bolts 25, the sealing cap 241 is opened, and the air is inflated into the inflation port 24. The gas enters the airbag tube 22 through the inflation port 24 and the one-way valve 221, and the airbag tube 22 is compressed and expanded, thereby squeezing the two ends of the opening of the rubber strip 23, so that the two ends of the opening of the rubber strip 23 are closely fitted with the inner wall of the sealing groove 11. At the same time, the airbag tube 22 itself expands and closely fits with the inner wall of the sealing groove 11. Under the fit of the rubber strip 23 and the airbag tube 22 and the sealing groove 11, triple sealing is achieved at the connection between the base body 1 and the cover 2, and the sealing effect is good. The sealing cap 241 is screwed on the inflation port 24 to seal it;

[0032] When the airbag tube 22 is damaged and causes gas leakage, the rubber strips 23 at both ends of the airbag tube 22 seal the opening of the sealing groove 11, so that the leaked gas cannot escape from the opening of the sealing groove 11. At the same time, a sealing ring gasket 242 is installed between the inflation port 24 and the sealing cap 241 for sealing, so that the leaked gas cannot escape from the inflation port 24, thereby ensuring the normal use of the sealing effect and having a simple and reasonable structure. The design of the airbag tube 22 and the rubber strip 23 can be reused. When the base body 1 is disassembled and maintained, there is no need to replace new seals, which saves the use cost and is practical.

[0033] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
