It will be appreciated that in some embodiments of the present application, such as embodiments in which the plurality of second sealing tapers 211 on the second mating portion 21 are spaced apart, the angle of inclination may be different to facilitate forming a plurality of sealing surfaces with different angles of inclination.
In order to further improve the sealing property at the interface of the first connection pipe 10 and the second connection pipe 20, in some embodiments of the present application, for example, in the embodiment where the first mating portion 11 further has a first sealing plane 112 between adjacent first sealing tapers 111, and the second mating portion 21 further has a second sealing plane 212 between adjacent second sealing tapers 211, as shown in figures 1 and 3, when the locking element 30 is connected with one of the first and second connection pipes 10 and 20, the locking element 30 presses the first or second butting part 11 or 21, so that the first sealing plane 112 conforms to the second sealing plane 212 and maintains the sealing state, so that the joint of the first connecting pipe 10 and the second connecting pipe 20 not only has a fitted sealing conical surface, but also has a fitted sealing plane, thereby further improving the sealing performance at the joint of the first connection pipe 10 and the second connection pipe 20.
Further, in order to improve the sealing performance between the first sealing plane 112 and the second sealing plane 212, referring to fig. 1 and fig. 3, a sealing groove 113 is further disposed on the first sealing plane 112, and a sealing ring 114 is installed in the sealing groove 113; or the second sealing plane 212 is further provided with a sealing groove 113, and a sealing ring 114 is installed in the sealing groove 113.

It is understood that the sealing ring 114 and the sealing groove 113 may also be disposed at the first sealing conical surface 111 and/or the second sealing conical surface 211 to further improve the sealing performance of the first sealing conical surface 111 and the second sealing conical surface 211.
In some embodiments of the present application, in order to achieve the inside-outside contact between the first sealing tapered surface 111 and the second sealing tapered surface 211, referring to fig. 1 and 3, the first sealing tapered surface 111 is located on the outer surface of the first connection pipe 10, and the second sealing tapered surface 211 is located on the inner surface of the second connection pipe 20; the locking element 30 is mounted on the outer surface of the second connection tube 20 to press the second butt portion 21 so that the first sealing tapered surface 111 and the second sealing tapered surface 211 are fitted into and sealed with each other. It is understood that the first sealing tapered surface 111 may be located on the inner wall surface of the first connection pipe 10 and the second sealing tapered surface 211 is located on the outer surface of the second connection pipe 20.
In some embodiments of the present application, for example, for embodiments in which the first sealing taper 111 is located on the outer surface of the first connection pipe 10 and the second sealing taper 211 is located on the inner surface of the second connection pipe 20, referring to fig. 5 and 7, the first butting part 11 includes a pressure-bearing table 110 located at one end of the first connection pipe 10, and the first sealing taper 111 is located outside the pressure-bearing table 110; the second mating portion 21 includes a bell mouth 210 at one end of the second connection pipe 20, and the second sealing cone 211 is located inside the bell mouth 210. When the locking element 30 is connected to the first connection tube 10, the locking element 30 presses the bell 210 against the pressure receiving table 110, so that the first sealing tapered surface 111 and the second sealing tapered surface 211 are attached and maintain a sealing state.
Further, in order to ensure that the locking element 30 sufficiently presses the flare 210 to have a sufficient pressing force, in some embodiments of the present application, referring to fig. 5, 7 and 8, fig. 8 shows a structural diagram of the locking element 30 in the embodiments of the present application, wherein the flare 210 has a plurality of pressing tapered surfaces 213 corresponding to the second sealing tapered surfaces 211 on the outer side, and the locking element 30 has a plurality of pressing tapered surfaces 311 corresponding to the pressing tapered surfaces 213; the locking element 30 presses the pressing tapered surface 213 through the pressing tapered surface 311 to make the first sealing tapered surface 111 and the second sealing tapered surface 211 fit inside and outside. Since each second sealing tapered surface 211 has a corresponding pressure tapered surface 213, the locking element 30 can press each pressure tapered surface 213 through a plurality of pressure tapered surfaces 311, so that each set of first sealing tapered surfaces 111 and second sealing tapered surfaces 211 can fit inside and outside and maintain a good seal.
It will be appreciated that in some embodiments of the present application, for example, for the embodiment where the first butt connection portion 11 further has a first sealing plane 112 between adjacent first sealing tapers 111 and the second butt connection portion 21 further has a second sealing plane 212 between adjacent second sealing tapers 211, the locking element 30 may further be provided with a corresponding pressing plane 312, and the second butt connection portion 21 may further be provided with a pressing plane 214 to ensure the sealing between the first sealing plane 112 and the second sealing plane 212.
To facilitate the connection of the locking element 30 with one of the first and second connection pipes 10 and 20, as an example, refer to fig. 1, 3 and 8, wherein the locking element 30 has a first connection thread 313 for connecting with one of the first and second connection pipes 10 and 20, and one of the first and second connection pipes 10 and 20 is provided with a second connection thread 115 for screwing with the first connection thread 313. Specifically, the present application will be described by taking an example in which the locking element 30 is connected to the first connecting pipe 10, and the first connecting pipe 10 is provided with the second connecting screw.
The locking element 30 is installed on the second connection pipe 20, a first connection thread 313 corresponding to an internal thread is arranged in the locking element 30, a second connection thread 115 corresponding to an external thread is arranged on the outer wall surface of the first connection pipe 10, the locking element 30 is connected with the first connection pipe 10 through screwing of the first connection thread 313 and the second connection thread 115, due to the axial locking force of the first connection thread 313 and the second connection thread 115, the first sealing conical surface 111 and the second sealing conical surface 211 are squeezed by the axial locking force, so that high contact pressure is formed between the first sealing conical surface 111 and the second sealing conical surface 211, and the contact pressure further prevents refrigerant leakage to ensure the sealing performance between the first sealing conical surface 111 and the second sealing conical surface 211.
It will be appreciated that the locking element 30 may also be connected to the first connecting tube 10 in other ways, such as a screw 13/bolt lock connection, a spring 142 connection, etc.
In order to prevent the locking element 30 from being unscrewed to reduce the axial locking force between the first connection thread 313 and the second connection thread 115, and finally reduce the contact pressure between the first sealing tapered surface 111 and the second sealing tapered surface 211 to generate refrigerant leakage, in some embodiments of the present application, referring to fig. 1 and 2, the locking element 30 is provided with a locking-back prevention tooth 314 on a side adjacent to the second connection thread 115; the first connection pipe 10 and the second connection pipe 20 are provided with a retaining clip 12 engaged with the retaining tooth 314, and one of the second connection threads 115 is attached. When the locking element 30 is connected to one of the first connecting pipe 10 and the second connecting pipe 20, the anti-back clip 12 is engaged with the anti-back clip 314, and due to the limitation of the anti-back clip 12 and the anti-back clip 314, the locking element 30 cannot rotate relative to the direction of unscrewing the first connecting thread 313 and the second connecting thread 115, so that the purpose of reducing the axial locking force of the first connecting thread 313 and the second connecting thread 115 caused by unscrewing the locking element 30 is achieved.
Further, in some embodiments of the present application, the anti-back-off card 12 may be directly and fixedly connected to the first connecting tube 10 or the second connecting tube 20, for example, when the locking element 30 is connected to the first connecting tube 10 or the second connecting tube 20, after the anti-back-off card 12 is engaged with the anti-back-off teeth 314, the anti-back-off card 12 may be directly and fixedly welded, so as to permanently fix the anti-back-off card 12 in a detachable manner and loosen the locking element 30.
In other embodiments of the present application, the anti-back-off card 12 may be detachably connected to the first connection pipe 10 or the second connection pipe 20, for example, referring to fig. 1, one of the first connection pipe 10 and the second connection pipe 20, which is provided with the second connection thread 115, is provided with a threaded hole 116, the anti-back-off card 12 has a rotation hole 121 opposite to the threaded hole 116, and the rotation hole 121 is internally provided with a screw 13 which is matched with the threaded hole 116. When the locking element 30 is connected to the first connecting tube 10 or the second connecting tube 20, and the anti-back card 12 is engaged with the anti-back latch 314, the anti-back card 12 is fixed by the cooperation of the screw 13 and the threaded hole 116, and the anti-back card 12 is detachably fixed.
In some embodiments of the present application, for example, for the embodiment of fixing the screw 13 of the anti-back-off card 12, referring to fig. 1 and fig. 2, one of the first connecting pipe 10 and the second connecting pipe 20 where the anti-back-off card 12 is installed is further provided with an anti-loose member 14 for limiting the anti-back-off card 12 to rotate along with the locking member 30 in the direction of unscrewing the locking member 30 around the first connecting thread 313 and the second connecting thread 115, so as to prevent the anti-back-off card 12 from rotating and further preventing the locking member 30 from being unable to be limited after the screw 13 is loosened.
Specifically, referring to fig. 1 and 2, in some embodiments of the present application, the anti-release element 14 may include a protrusion 141 for limiting the rotation of the anti-release card 12, and the protrusion 141 is disposed in a direction in which the anti-release card 12 allows the first connection thread 313 and the second connection thread 115 to be unscrewed, for example, when the anti-release card 12 rotates clockwise to allow the locking element 30 to be unscrewed, the protrusion 141 is disposed on a side of the anti-release card 12 that rotates clockwise, so as to limit the anti-release card 12 from rotating clockwise by the protrusion 141.
With continued reference to fig. 1 and 2, in some embodiments of the present application, the locking member 14 includes a spring 142 for limiting the rotation of the anti-reverse card 12, and one end of the spring 142 is connected to one of the first connecting pipe 10 and the second connecting pipe 20 where the anti-reverse card 12 is installed, and the other end is connected to the anti-reverse card 12.
As an example, when the spring 142 is a tension spring 142, the spring 142 extends in a direction opposite to the direction in which the check card 12 unscrews the first connection screw 313 and the second connection screw 115, for example, when the check card 12 rotates clockwise to unscrew the locking member 30, the spring 142 continues in a counterclockwise direction to restrict the check card 12 from rotating clockwise by the tension of the spring 142 on the counterclockwise side.
As another example, when the spring 142 is a thrust spring 142, the spring 142 extends in the same direction as the direction in which the first connection screw 313 and the second connection screw 115 are unscrewed by the check card 12, for example, when the check card 12 is rotated clockwise to unscrew the locking member 30, the spring 142 continues in a clockwise direction to restrict the clockwise rotation of the check card 12 by the thrust of the spring 142 on the clockwise side.
It should be noted that the protruding columns 141 and the springs 142 can limit the rotation of the anti-back-off clip 12 in the direction of loosening the locking element 30, and the rotation of the anti-back-off clip 12 in the direction of tightening the locking element 30 can be limited, so that the locking element 30 can be tightened after the structures of the springs 142 and the protruding columns 141 are installed, and the threaded connection strength between the locking element 30 and the first connection pipe 10 or the second connection pipe 20 is ensured.
It can be understood that the protruding pillar 141 and the spring 142 can be disposed on the side of the anti-rotation clip 12 where the first connection thread 313 and the second connection thread 115 are loosened or in the opposite direction, so as to limit the rotation of the locking element 30 in the tightening direction by the anti-rotation clip 12, thereby avoiding the excessive tightening torque of the locking element 30.
