DETAILED DESCRIPTION
[0028] The following is combined with Figure 1 -Attached Figure 2 , further details of this application are given.
[0029] A rotatable gas-electric hybrid interface connection structure, referring to Figure 1 , including two gas-electricity pipelines 1 for gas-electricity transmission, one of which is used to connect the air pump, and the other is used to connect the airbag. One of the gas-electricity pipelines 1 is connected to a fixed shell 2, and the other gas-electricity pipeline 1 is connected to a connecting shell 3, and both the fixed shell 2 and the connecting shell 3 are circular in design.
[0030] Reference Figure 1 The fixed shell 2 is also provided with a connection hole 23 interconnected with the gas-electricity pipeline 1, and the connecting shell 3 is provided with a gas nozzle 33 interconnected with the gas-electricity pipeline 1. The gas nozzle 33 and the connecting hole 23 are both circular, and the gas nozzle 33 and the connecting hole 23 are adapted to each other. The gas nozzle 33 can be inserted into the connecting hole 23 and abut against the inner wall of the connecting hole 23. When using this gas-electricity hybrid interface, the connecting shell 3 and the fixed shell 2 are buckled together, and the gas nozzle 33 can be inserted into the connecting hole 23. Through the connection between the gas nozzle 33 and the connecting hole 23, the ventilation connection between the two gas-electricity pipelines 1 can be realized. At the same time, the gas nozzle 33 abuts against the inner wall of the connecting hole 23, which can play a fixing role between the connecting shell 3 and the fixed shell 2.
[0031] Reference Figure 1A fixing ring 21 is integrally provided in the shell of the fixed shell 2. There are several fixing rings 21. The fixing ring 21 is circular and coaxially arranged with the connecting hole 23. A conductive sheet 22 for conducting electricity is provided on the side wall of the fixing ring 21. A connecting ring 31 is provided in the shell of the connecting shell 3. The connecting ring 31 is circular and coaxially arranged with the gas nozzle 33. A conductive ring 32 is detachably connected and provided on the side wall of the connecting ring 31 by bonding. The length direction of the conductive ring 32 is arranged along the length direction of the connecting ring 31. When the connecting shell 3 and the fixed shell 2 are buckled with each other, the connecting ring 31 is inserted between the fixing rings 21. At this time, the conductive sheet 22 can abut against the surface of the conductive ring 32, and the electrical connection between the two gas-electric pipelines 1 is realized by the contact between the conductive sheet 22 and the conductive ring 32. The connecting shell 3 and the fixed shell 2 can rotate relative to each other. During the rotation, the air nozzle 33 always remains connected to the connecting hole 23, the conductive sheet 22 slides on the surface of the conductive ring 32, and the conductive sheet 22 always remains in contact with the surface of the conductive ring 32. Even if the gas-electric hybrid interface rotates during use, normal ventilation and power supply can still be maintained.
[0032] Reference Figure 1 and Figure 2 The conductive sheet 22 includes a mounting sheet 221 and a contact sheet 222. The mounting sheet 221 and the contact sheet 222 are integrally formed, the contact sheet 222 and the mounting sheet 221 are bent, and the mounting sheet 221 and the fixing ring 21 are connected to each other. When the connecting shell 3 and the fixing shell 2 are buckled together, the contact sheet 222 and the mounting sheet 221 can be deformed, and the contact sheet 222 and the surfaces of the conductive ring 32 are abutted against each other to realize the power supply between the connecting shell 3 and the fixing shell 2. The bent conductive sheet 22 can play a guiding role, which facilitates the buckling of the connecting shell 3 and the fixing shell 2.
[0033] Reference Figure 1 and Figure 2 A mounting groove 4 for inserting the mounting piece 221 is provided on the side wall of the fixing ring 21 , and a protrusion is integrally provided on the mounting piece 221 , and the mounting piece 221 is engaged with the inner wall of the mounting groove 4 to facilitate the disassembly and assembly of the conductive piece 22 .
[0034] Reference Figure 1 A sealing ring 5 is fixedly provided on the outer wall of the air nozzle 33. The length direction of the sealing ring 5 is arranged along the circumferential direction of the air nozzle 33. A sealing groove 51 for inserting the sealing ring 5 is opened on the inner wall of the connecting hole 23. When the air nozzle 33 and the connecting hole 23 are connected to each other, the sealing ring 5 can be inserted into the sealing groove 51. The sealing ring 5 is abutted against the inner wall of the sealing groove 51. When the air nozzle 33 and the connecting hole 23 rotate, the sealing ring 5 slides in the sealing groove 51, which further improves the sealing performance and prolongs the service life of the sealing ring 5.
[0035] Reference Figure 1, a snap ring 6 is arranged on the shell of the connecting shell 3, the snap ring 6 is located outside the connecting ring 31, the snap ring 6 is circular and is arranged coaxially with the connecting ring 31. A group of blocks 7 are symmetrically arranged on the shell of the fixed shell 2, the snap ring 6 can rotate with the fixed shell 2 under the action of toughness, and a protrusion 71 is arranged on the side wall of the block 7. A slot 61 for the block 7 to be inserted and abutted is arranged on the inner wall of the snap ring 6, and the length direction of the slot 61 is arranged along the circumferential direction of the snap ring 6. When the connecting shell 3 and the fixed shell 2 are buckled with each other, the protrusion 71 can be pressed first to drive the block 7 to approach the shell of the fixed shell 2. After the connecting shell 3 and the fixed shell 2 are completely buckled, the protrusion 71 is released. Under the deformation ability of the block 7 itself, the block 7 is automatically inserted into the slot 61, and the block 7 can abut against the inner wall of the slot 61, which is conducive to improving the fixing effect between the connecting shell 3 and the fixed shell 2.
[0036] The implementation principle of the embodiment of the present application is:
[0037] When using this gas-electric hybrid interface, the connecting shell 3 and the fixed shell 2 are buckled together. At this time, the gas nozzle 33 can be inserted into the connecting hole 23. Through the connection between the gas nozzle 33 and the connecting hole 23, the ventilation connection between the two gas-electric pipelines 1 can be realized. At the same time, the gas nozzle 33 abuts against the inner wall of the connecting hole 23, which can play a fixing role between the connecting shell 3 and the fixed shell 2; while buckling, the connecting ring 31 is inserted between the fixed ring 21, and at this time, the conductive sheet 22 can abut against the surface of the conductive ring 32, and the electrical connection between the two gas-electric pipelines 1 is realized by using the contact between the conductive sheet 22 and the conductive ring 32; when this gas-electric hybrid interface connection structure is actually used, the connecting shell 3 and the fixed shell 2 can rotate with each other. During the rotation, the gas nozzle 33 always keeps in connection with the connecting hole 23, and the conductive sheet 22 always keeps in contact with the surface of the conductive ring 32. Therefore, even if the gas-electric hybrid interface rotates during use, it can still keep power on and ventilation at the same time, which meets the function of the interface rotating 360 degrees, and improves the convenience and applicability of operation.
