[0026] As Figures 1 to 4 As shown, a connection structure of engine components according to an embodiment of the present invention includes: a first conical surface fastening flange 1, a first conical surface seal 2, a first seal body 3, a connecting piece 4, and a plurality of first O-rings 5. One end of the first conical surface seal 2 is fixedly connected to one end of the first conical surface fastening flange 1, and a first accommodation space is formed inside. The first seal body 3 is arranged in the first accommodation space. One end of the connecting piece 4 is fixedly arranged in the first seal body 3. And a plurality of first O-rings 5 are arranged between one end of the connecting piece 4 and the first seal body 3. Among them, one end of the connecting piece 4 can be adjusted along the axial direction in the first seal body 3.

[0027] In one or more embodiments, the connection structure of the engine components further includes a first snap ring 6, which is clamped at the connection between the first conical surface fastening flange 1 and the first conical surface seal 2. The first seal body 3 is a spherical seal body. The number of the plurality of first O-rings 5 is two.

[0028] In one or more embodiments, the connection structure of the engine components further includes: a second conical fastening flange 7, a second conical seal 8, a second sealing body 9, and a plurality of second O-rings 10. One end of the second conical seal 8 is fixedly connected to one end of the second conical fastening flange 7, and a second accommodation space is formed inside. The second sealing body 9 is disposed in the second accommodation space, and the other end of the connecting member 4 is fixed in the second sealing body 9. And a plurality of second O-rings 10 are disposed between the other end of the connecting member 4 and the second sealing body 9. Wherein, the other end of the connecting member 4 can be adjusted along the axial direction in the second sealing body 9.

[0029] In one or more embodiments, the connection structure of the engine components further includes a second snap ring 11, which is clamped at the connection between the second conical fastening flange 7 and the second conical seal 8. The second sealing body 9 is a spherical sealing body. The number of the plurality of second O-rings 10 is two.

[0030] In practical applications, the connection structure of the engine components of the present invention is arranged as follows: There is a sealing form of a sealing structure formed by two O-rings between the spherical inner cavity (the first sealing body 3 or the second sealing body 9) and the connecting pipe (the connecting member 4). Due to the use of O-ring sealing, the connecting member 4 can be adjusted along the axial direction inside the spherical sealing body (the first sealing body 3 or the second sealing body 9).

[0031] Adopting a combined structure sealing form of double conical surfaces and a spherical surface, with a sphere sandwiched between two conical surfaces, even if there is an angle between the axis of one end of the connecting member 4 and the axis of the other end of the connecting member 4, an effective sealing line can be formed between the spherical sealing body (the first sealing body 3 or the second sealing body 9) and the conical seal (the first conical seal 2 or the second conical seal 8), which can effectively connect the spherical sealing body and the conical seal while ensuring the sealing performance. The connection between the spherical sealing body and the conical fastening flange is also sealed through the spherical surface and the conical surface. Even if there is a certain angle between the conical fastening flange and the flange of the conical seal, the pressing structure formed by the snap ring of the conical fastening flange and the conical seal can effectively press and seal the spherical sealing body.

[0032] Through the sealing of two O-rings and the double conical surface pressing seal, double adjustment in the axial direction and the angular direction between the connecting member 4 and the conical seal can be formed. The angle adjustment range is: as Figure 4 shown, it is adjusted within the conical surface range of the α angle formed with the axial direction of the conical seal. Adopting a double-link structure can ensure the connection of two parts in a spatial position relationship.
