[0002] The Czochralski method is a commonly used method for growing single crystals at present. Its working principle is to place the raw materials constituting the crystal in a crucible and heat them to melt. A seed crystal is picked up on the surface of the melt, and under controlled conditions, the seed crystal and the melt continuously rearrange atoms or molecules at the interface, and gradually solidify with the decrease in temperature to grow a single crystal. At present, the connection between the feeding quartz tube of some single crystal furnaces and the weight is carried out by directly connected hooks, which is complex in operation, prone to interference, and may lead to accidents. At the same time, it is not convenient to disassemble the weight connection mechanism and cannot meet the function of refeeding the existing feeding quartz tube. Therefore, we propose a connection mechanism between a feeding quartz tube and a weight to solve the above problems. Content of the Utility Model

The bottom of the weight connection seat is in movable contact with a circular connection seat. The bottom of the circular connection seat is in movable contact with a connecting pipe. A groove is opened at the bottom of the weight connection seat. A tapered hole is opened at the top of the circular connection seat. The connecting pipe, the groove and the tapered hole are communicated with each other. An umbrella-shaped lifting rod is in movable contact with the top of the circular connection seat. The umbrella-shaped lifting rod is located inside the groove. A first threaded groove is opened at the top of the weight connection seat. An annular block is slidably connected to the outside of the circular connection seat. Two connecting rods are rotatably connected to the bottom of the annular block. The bottom ends of the connecting rods are rotatably connected to a cross bar. A vertical rod is fixedly connected to the end of the cross bar.

[0005] Further preferably, L-shaped rods are fixedly connected to the sides of the two vertical rods close to each other. Two second threaded grooves are opened on both sides of the weight connection seat and the connecting pipe.

[0017] Embodiment

[0018] Please refer to Figures 1-3, the present utility model provides a technical solution: a connection mechanism between a feeding quartz cylinder and a weight, including a weight connection seat 1. The bottom of the weight connection seat 1 is in movable contact with a circular connection seat 2. The bottom of the circular connection seat 2 is in movable contact with a connecting pipe 3. A groove 4 is formed at the bottom of the weight connection seat 1. A conical hole 5 is formed at the top of the circular connection seat 2. The connecting pipe 3, the groove 4 and the conical hole 5 are communicated. An umbrella-shaped lifting rod 6 is in movable contact with the top of the circular connection seat 2. The umbrella-shaped lifting rod 6 is located inside the groove 4. A first thread groove 7 is formed at the top of the weight connection seat 1. An annular block 8 is slidably connected to the outside of the circular connection seat 2. Two connecting rods 9 are rotatably connected to the bottom of the annular block 8. The bottom ends of the connecting rods 9 are rotatably connected to a cross bar 10. A vertical rod 11 is fixedly connected to the end of the cross bar 10. By threading an external screw rod with the first thread groove 7, the external screw rod is lifted. The external screw rod drives the circular connection seat 2 and the connecting pipe 3 to move upward through the weight connection seat 1. After being lifted, it is stable and not likely to contact the lower edge of the auxiliary chamber with the feeding quartz cylinder, avoiding interference. Reverse rotation of the bolt 13 separates it from the corresponding second thread groove 17. The annular block 8 moves and rotates through the connecting rod 9, so that the upper L-shaped rod 12 is separated from the weight connection seat 1, and the lower L-shaped rod 12 is separated from the connecting pipe 3, separating the weight connection seat 1, the circular connection seat 2 and the connecting pipe 3. During use, the operation is simple, not likely to cause interference, avoiding accidents. At the same time, it is convenient to disassemble the weight connection mechanism and can meet the function of refeeding the existing feeding quartz cylinder.

[0019] In this embodiment, specifically: L-shaped rods 12 are fixedly connected to the sides of the two vertical rods 11 close to each other. Two second thread grooves 17 are formed on both sides of the weight connection seat 1 and the connecting pipe 3;

[0020] In this embodiment, specifically: A bolt 13 is threadedly connected to the second thread groove 17. The L-shaped rod 12 is threadedly sleeved on the outside of the corresponding bolt 13. The setting of the bolt 13 plays a fixing effect;

[0021] In this embodiment, specifically: Positioning rods 14 are fixedly connected to both sides of the circular connection seat 2. Circular blocks 15 are fixedly connected to the ends of the positioning rods 14;

[0022] In this embodiment, specifically: The vertical rod 11 is slidably sleeved on the outside of the positioning rod 14;

[0023] In this embodiment, specifically: The same spring 16 is fixedly connected between the vertical rod 11 and the corresponding circular block 15;

[0024] In this embodiment, specifically: The spring 16 is slidably sleeved on the outside of the corresponding positioning rod 14.

[0025] When the utility model is in operation: during use, the external screw is threadedly connected to the first thread groove 7 to lift the external screw. The external screw drives the circular connecting seat 2 and the connecting pipe 3 to move upward through the weight connecting seat 1. After being lifted, it is stable and not prone to contact between the lower edge of the auxiliary chamber and the quartz cylinder of the feeder, avoiding interference. At the same time, when the feeding quartz cylinder and the weight connecting seat 1 are centered, the connection operation can be carried out by relying on their own gravity, realizing the function of automatic feeding on the furnace platform and avoiding the participation of personnel. When it is necessary to separate the weight connecting seat 1, the circular connecting seat 2 and the connecting pipe 3, reverse-rotate the bolt 13 to separate it from the corresponding second thread groove 17. Then, hold the circular ring block 8 and move it downward. The circular ring block 8 squeezes the two connecting rods 9. Under the action of the squeezing force, the connecting rod 9 moves and rotates. The connecting rod 9 drives the cross bar 10 to move, and the cross bar 10 drives the vertical rod 11 to move. The vertical rod 11 slides on the outside of the positioning rod 14 and compresses the spring 16. The vertical rod 11 drives the corresponding L-shaped rod 12 to move. The upper L-shaped rod 12 is separated from the weight connecting seat 1, and the lower L-shaped rod 12 is separated from the connecting pipe 3. At this time, the weight connecting seat 1, the circular connecting seat 2 and the connecting pipe 3 can be separated, thus constituting a connection mechanism between the feeding quartz cylinder and the weight. During use, the operation is simple, not prone to interference, avoiding accidents, and at the same time facilitating the disassembly of the weight connection mechanism, meeting the function of refeeding the existing feeding quartz cylinder.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
