Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 and fig. 2, the present invention provides a technical solution: a silica gel system expansion type pan sealing ring convenient for replacement is used on a pressure cooker cover, pressure cookers produced by different manufacturers have different structures, therefore, the silica gel sealing ring uses the matched pressure cooker cover, and the matched pressure cooker cover needs to be provided with a circle of annular clamping groove in the cover in the manufacturing process, the silica gel sealing ring is used for splicing a rubber air bag 3, and after the rubber air bag 3 expands, the rubber air bag 3 can be clamped in the annular clamping groove of the cover to realize the fixation of the sealing ring, therefore, the sealing ring can be installed and taken down by inflating and deflating the rubber air bag 3, the pot is convenient to replace, the silica gel sealing ring 1 comprises a silica gel ring 1, the silica gel ring 1 can be contacted with the pot body to play a role of sealing the inner cavity of the pot cover after being buckled, the left side wall of the silica gel ring 1 is provided with an annular groove 2, the inner side wall of the annular groove 2 is fixedly provided with the rubber air bag 3, the air pressure inside the rubber airbag 3 is higher than the air pressure of the outside air after the rubber airbag 3 is expanded, the inner side wall of the silica gel ring 1 is provided with a round hole 4, the inner side wall of the round hole 4 is fixedly provided with a cylindrical block 5, the lower side wall of the cylindrical block 5 is provided with a through hole 6, an air needle for inflating the rubber airbag 3 is inserted into the through hole 6, the inner side wall of the through hole 6 is provided with an inclined plane annular groove 7, the diameter of the inclined plane annular groove 7 facing the inner side of the silica gel ring 1 is smaller than that facing the outer side of the silica gel ring 1, the lower side of the inner side wall of the inclined plane annular groove 7 is provided with an annular limiting groove 8, the diameter of the annular limiting groove 8 is slightly larger than the minimum diameter of the inclined plane annular groove 7, the upper side of the inner side wall of the inclined plane annular groove 7 is inserted with a rubber circular plate, at this time, the air needle can be inserted into the through hole 6, the air needle can contact the rubber circular plate 9 and pass through the small hole 10, because the diameter of the air needle is larger than that of the small hole 10, friction force can be generated between the air needle and the small hole 10, then inflation work can be carried out, after inflation is finished, the air needle is pulled out, because the friction force between the air needle and the small hole 10 can drive the rubber circular plate 9 to move downwards in the inclined plane annular groove 7, the inner wall of the inclined plane annular groove 7 generates friction force on the rubber circular plate 9, and further the friction force between the air needle and the small hole 10 is increased until the rubber circular plate 9 moves to the annular limiting groove 8, the air needle can be pulled out when force is applied again, and because the rubber 9 is positioned in the annular limiting groove 8 with a relatively smaller diameter, the elastic action of the rubber material can block the small hole 10, otherwise, when the air needle is inserted again, the air needle can firstly push the rubber circular plate 9 out of the annular limiting groove 8 and move to the upper position in the annular groove 7, afterwards, the air needle can be deflated or inflated again through the small hole 10, so that the air circulation between the rubber air bag 3 and the external space is avoided, the square hole 11 is formed in the outer side wall of the rubber air bag 3, and the square hole 11 is communicated with the through hole 6.
Specifically, the inside wall of square hole 11 evenly fixed mounting has rubber valve 12, and the inner of rubber valve 12 all closely laminates each other, and rubber valve 12 plays one-way circulation effect to the air at ordinary times, and when the air needle inserted and passed through rubber valve 12, the air in the rubber gasbag 3 just can be discharged through the air needle.
Particularly, the conical groove 13 is formed in the lower side of the inner side wall of the through hole 6, so that the air needle can be conveniently inserted.
Specifically, the upper and lower side walls of the rubber circular plate 9 are symmetrically provided with grooves 14, which facilitate the insertion of the air needle into the small hole 10.
The working principle is as follows: this silica gel system inflation formula pan sealing ring convenient to change, insert the gas needle from through-hole 6 earlier, the gas needle passes through aperture 10 in proper order, square hole 11 and rubber valve 12, make 3 internal gas pressures of rubber gasbag the same with external world, then arrange the ring groove of pot cover in with the left side of rubber gasbag 3, then aerify through the gas needle, make 3 expansion card of rubber gasbag in the ring groove of pot cover, extract the gas needle again, the installation of this sealing ring has been accomplished promptly, when needing to take off the sealing ring, insert the gas needle and deflate can, therefore this silica gel sealing ring can be convenient to the assorted pot cover completion change operation.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
