[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] The utility model provides a technical solution, please refer to Figure 1-5 :

[0025] A material placing base structure for a vacuum sintering furnace includes a material tray 1, an air pipe 2, a connecting rod 3 and a connecting pipe 9. The air pipe 2 extends into a connecting hole 6 opened on a fixed block 5. A sealing ring 7 is provided on the outer sleeve of the air pipe 2, and the bottom of the sealing ring 7 abuts against the fixed block 5. Therefore, after the air pipe 2 is connected to the connecting pipe 9, gas leakage at the connection can be effectively prevented. A connecting pipe 9 is fixed on the outer wall of the fixed block 5, and the connecting pipe 9 and the air pipe 2 are internally connected through the connecting hole 6 of the fixed block 5. A fixing piece for fixing the connecting pipe 9 and the air pipe 2 is provided on the connecting rod 3.

[0026] Embodiment 2:

[0027] The technical solution is basically the same as that of the first embodiment, except that Figure 4 As shown, the fixing member includes a slide groove 4 provided on the connecting rod 3, and a slide rod 10 is slidably connected to the slide groove 4, a cross block 11 is fixed on the slide rod 10, a screw hole 12 is provided on the cross block 11, and the screw hole 12 is connected to the screw rod 13 by a thread, a top block 15 is fixed to the end of the screw rod 13, and the top block 15 abuts against the disc 8 at the bottom of the fixing block 5. A handle 14 is fixed to the bottom of the screw rod 13, and the screw rod 13 can be rotated conveniently by the handle 14, so that the operation is more convenient.

[0028] Embodiment three:

[0029] The technical solution is basically the same as that of the first embodiment, except that Figure 4 and Figure 5 As shown, a protrusion 17 is protruding from the bottom of the disc 8, and a groove 16 matching the protrusion 17 is formed on the top block 15. Therefore, after the protrusion 17 is inserted into the groove 16, the air pipe 2 can remain vertically inserted into the connecting hole 6 during the upward movement of the fixed block 5, so that the air pipe 2 can be prevented from being skewed after being connected to the connecting pipe 9. One end of the spring 18 is fixed to the protruding part of the connecting rod 3, and the other end of the spring 18 is fixedly connected to the slide bar 10. Under the elastic force of the spring 18, when the connecting pipe 9 is disassembled, the slide bar 10 can drive the top block 15 away from the bottom of the air pipe 2, so that the connecting pipe 9 can be removed easily.

[0030] In summary, when the connecting tube 9 provided in this embodiment needs to be replaced, the handle 14 can be rotated to move the top block 15 downward until the protrusion 17 is separated from the groove 16. Under the elastic force of the spring 18, the slide bar 10 and the cross block 11 are away from the bottom of the disc 8 until there is no obstruction under the disc 8. Pull the disc 8 downward to separate the connecting tube 9 from the trachea 2. Then the new connecting tube 9 can be connected to the trachea 2. The connection method of the connecting tube 9 and the trachea 2 can refer to the above disassembly process.

[0031] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
