[0002] A quartz furnace tube is a tubular container made of quartz material. It has good high-temperature resistance, high chemical stability, high transparency and good electrical insulation performance. It is often used in scenarios such as semiconductor manufacturing, chemical experiments and industrial production.

[0003] The existing utility model with authorization announcement number CN220728911U discloses a tubular furnace quartz tube structure. A groove is set on the middle plug plate to fix the porcelain boat to prevent the porcelain boat from tipping over and spilling the material. The porcelain boat can be moved in and out by sliding the plug plate, which is convenient for adding and sampling. It has the characteristics of simple operation, quickness and time saving.

[0004] Although the above technical solution is convenient for adding and taking samples, and has the characteristics of simple operation, quickness and time-saving, the port of the above technical solution is in a completely open state, and lacks a convenient sealing structure for quickly sealing the port. As a result, it is difficult to ensure the sealing of the port in scenarios where the quartz furnace tube requires high pressure or is prone to produce harmful gases, and thus the application effect of the quartz furnace tube is difficult to meet different application scenarios.

[0005] Therefore, those skilled in the art provide a quartz furnace tube with a sealing structure to solve the problems raised in the above background technology. Utility Model Content

[0008] A quartz furnace tube with a sealing structure comprises a quartz furnace tube body, wherein a convenient sealing mechanism is provided on the outer side of the quartz furnace tube body;

[0009] The convenient sealing mechanism includes a fixed shell, a movable shell is provided on the outside of the fixed shell, the inner wall of the fixed shell and the outer surface of the quartz furnace tube body are fixedly connected with a heat-resistant ceramic ring, the front of the fixed shell is fixedly connected with a heat-resistant sealing soft ring, the back of the movable shell is fixedly connected with two positioning columns, the inner wall of the movable shell is threadedly connected with two hand-tightening bolts, each of the positioning columns is fixedly connected to a first magnetic block at one end away from the movable shell, and the inner wall of the fixed shell is fixedly connected with two second magnetic blocks.

[0022] See also Figure 1-4 A quartz furnace tube with a sealing structure includes a quartz furnace tube body 1. A convenient sealing mechanism 2 is provided on the outside of the quartz furnace tube body 1. The convenient sealing mechanism 2 includes a fixed shell 201. A movable shell 202 is provided on the outside of the fixed shell 201. Two mounting plates 3 are provided under the quartz furnace tube body 1. A plurality of identical mounting holes 4 are opened on the upper surface of each mounting plate 3. By setting the mounting holes 4, the mounting plates 3 can be fixed in the docking installation position in conjunction with external bolts and other structures, and then the quartz furnace tube body 1 can be fixed in conjunction with other frame structures, thereby increasing the placement stability of the quartz furnace tube body 1.

[0023] The inner wall of the fixed shell 201 and the outer surface of the quartz furnace tube body 1 are fixedly connected with a heat-resistant ceramic ring 203, the front of the fixed shell 201 is fixedly connected with a heat-resistant sealing soft ring 204, the back of the movable shell 202 is in contact with the front of the heat-resistant sealing soft ring 204, the outer surface of the quartz furnace tube body 1 is fixedly connected with a heat-resistant frame 5, and the upper surface of each mounting plate 3 is fixedly connected to the bottom surface of the heat-resistant frame 5. By setting up the heat-resistant frame 5, it itself has good heat resistance, and it is convenient to cooperate with the mounting plate 3 and the mounting hole 4 to fix the quartz furnace tube body 1, thereby increasing the placement stability of the quartz furnace tube body 1.

[0024] Two positioning columns 205 are fixedly connected to the back of the movable shell 202, and the inner wall of the movable shell 202 is threadedly connected to two hand-tightening bolts 208. The outer surface of each positioning column 205 contacts the inner wall of the fixed shell 201, and the outer surface of each hand-tightening bolt 208 is threadedly connected to the inner wall of the fixed shell 201. The outer surface of the heat-resistant frame 5 is fixedly connected to two handle supports 6, and the inner wall of each handle support 6 is fixedly connected to a pull rod 7. By setting the pull rod 7, a rotation base surface can be provided for the hand-gripping structure in the handle support 6, thereby increasing the flexibility of use of the hand-gripping structure. By setting the handle support 6 and the pull rod 7, the above-mentioned hand-gripping structure can be cooperated to lift the entire quartz furnace tube body 1.

[0025] One end of each positioning column 205 away from the movable shell 202 is fixedly connected to the first magnetic block 206, and a grip 8 is provided inside each handle support 6. The inner wall of each grip 8 is rotatably connected to the outer surface of the pull rod 7. By providing the grip 8, it can rotate around the outer surface of the pull rod 7 inside the handle support 6, and then the quartz furnace tube body 1 can be conveniently moved after being grasped by hand.

[0026] Two second magnetic blocks 207 are fixedly connected to the inner wall of the fixed shell 201, and the front of each second magnetic block 207 is in contact with the back of the first magnetic block 206. The outer surface of the movable shell 202 is fixedly connected to an anti-slip sleeve 9, and the outer surface of the anti-slip sleeve 9 is fixedly connected to several identical anti-slip convex discs 10. By setting the anti-slip convex discs 10, the anti-slip property of the outer surface of the anti-slip sleeve 9 can be increased. By setting the anti-slip sleeve 9 and the anti-slip convex discs 10, the anti-slip property of the outer surface of the movable shell 202 can be jointly increased.

[0027] The working principle of the present invention is as follows: when in use, the handle 8 can be held by hand to stably move the quartz furnace tube body 1. When it is necessary to increase the stability of the quartz furnace tube body 1, the mounting plate 3 can be fixedly docked with the corresponding fixed docking structure by using a fixing pin structure such as an external bolt in conjunction with the mounting hole 4. When it is necessary to open and use the quartz furnace tube body 1, the hand-tightening bolt 208 is twisted to make the hand-tightening bolt 208 leave the fixed shell 201, and then the anti-slip sleeve 9 and the anti-slip convex plate 10 on the outer surface of the movable shell 202 are pinched to pull the movable shell 202 and the positioning column 205 away from the fixed shell 201. At the same time, the first magnetic block 206 is away from the second magnetic block 207, and the front port of the quartz furnace tube body 1 is exposed. When the quartz furnace tube body 1 is used and it is necessary to prevent the harmful gas or harmful smoke inside it from overflowing, the positioning column 205 is inserted into the quartz furnace tube body 1. The first magnetic block 206 and the second magnetic block 207 are magnetically attracted to each other. When a high-pressure environment needs to be created in the quartz furnace tube body 1, on the basis of the magnetic attraction of the first magnetic block 206 and the second magnetic block 207, the two hand-tightening bolts 208 are screwed and the two hand-tightening bolts 208 are threadedly connected to the fixed shell 201. This facilitates the rapid sealing of the port of the quartz furnace tube body 1 and improves the application effect and application scenarios of the quartz furnace tube. The design of the quartz furnace tube with a sealing structure effectively solves the problem that the lack of a convenient sealing structure for facilitating rapid sealing of the port makes it difficult to ensure the sealing of the port in scenarios where the quartz furnace tube requires high pressure or is prone to generating harmful gases, thereby making it difficult for the application effect of the quartz furnace tube to meet different application scenarios.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
