[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] This embodiment provides a connection assembly between a vacuum device and a vacuum tube, such as Figure 1-Figure 3 As shown, including:

[0022] A first connecting pipe 1, one end of which is provided with an internal thread;

[0023] A cylindrical disk 2, a second connecting tube 3 is provided on one side of the cylindrical disk 2, and an external thread is provided on the second connecting tube 3 to match the internal thread of the end of the first connecting tube 1, and a third connecting tube 3 is provided on the other side of the cylindrical disk 2, and the third connecting tube 3 is provided with an external thread;

[0024] The truncated cone disk 4 has a through hole in the middle thereof, and the through hole has an internal thread matched with the third connecting pipe 5. The end surface of the truncated cone disk 4 has a plurality of annular protrusions 6 of different diameters, and the plurality of annular protrusions 6 of different diameters are arranged at equal intervals. In actual use, the threaded connection improves the overall air tightness, and the plurality of annular protrusions 6 can abut against the end surface of the cylindrical disk 2, further improving the overall air tightness.

[0025] The above embodiment is further optimized, and a plurality of strip-shaped protrusions are arranged on the side of the cylindrical disk 2. The arrangement of the strip-shaped protrusions has the effect of increasing friction, so that it is convenient for a person to remove the cylindrical disk 2 from the first connecting pipe by rotating it.

[0026] The above embodiment is further optimized, and a clamping block 7 for convenient wrench connection is provided between the second connecting pipe 3 and the cylindrical disk 2. When the connection is too tight, the clamping block 7 can be connected by a wrench, so that disassembly is easier to achieve.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
