Obviously, the described embodiments are 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.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] refer to Figure 1 and Figure 2 The utility model provides a quartz tube processing auxiliary bottom sealing component, comprising:

[0027] A sealing end cover 1 is provided with an air inlet 3 communicating with the interior of the quartz tube 2. The sealing end cover 1 is provided at the open end of the quartz tube 2 and inflates the interior of the quartz tube 2 through the air inlet 3.

[0028] A sealing connector 4, which is used to detachably connect the sealing end cover 1 to the open end of the quartz tube 2. The sealing connector 4 includes an annular inflatable airbag 41 sleeved on the outer edge surface of the open end of the quartz tube 2 and an inflatable member 42 for inflating the annular inflatable airbag 41. The annular inflatable airbag 41 is a flexible inflatable airbag. An embedded groove 43 for placing the annular inflatable airbag 41 is provided at a position corresponding to the annular inflatable airbag 41 on the sealing end cover 1. The end surface of the embedded groove 43 in contact with the outer edge surface of the quartz tube 2 is provided with a flexible protective layer 5;

[0029] The inflatable end of the inflatable member 42 extends out of the sealing end cover 1. The number of the annular inflatable airbag 41 is at least one. In this example, one annular inflatable airbag 41 is provided. The transverse cross-section of the annular inflatable airbag 41 is circular or rectangular. In this example, the transverse cross-section of the annular inflatable airbag 41 is circular.

[0030] refer to Figure 1 and Figure 2 When working, the sealing end cover 1 is covered on the open end of the quartz tube 2. At this time, the embedded groove 43 set on the sealing end cover 1 is against the outer edge surface of the quartz tube 2, and the inner wall of the sealing end cover 1 does not contact the outer edge surface of the quartz tube 2. Since a flexible protective layer 5 is provided on the bottom surface of the embedded groove 43, and the inner wall of the sealing end cover 1 does not contact the outer edge surface of the quartz tube 2, the outer edge surface of the quartz tube 2 is protected to avoid wear of the outer edge surface of the quartz tube 2; thereafter, the annular inflatable airbag 41 is inflated through the inflatable member 42. The bag 41 is a flexible inflatable bag. After being inflated, the annular inflatable bag 41 expands and the sealing end cover 1 is firmly and tightly fixed on the outer edge surface of the open end of the quartz tube 2 under the action of the embedded groove 43. At the same time, the inner surface of the annular inflatable bag 41 is tightly wrapped on the outer edge surface of the quartz tube 2 to play a sealing role. Finally, air is inflated into the interior of the quartz tube 2 through the air inlet hole 3. Under the action of air pressure, one end of the hot-melt bottom seal of the quartz tube extends outward and expands, so that the outer cylindrical surface of one end of the hot-melt bottom seal of the quartz tube is extruded into an arc shape, thereby processing the actual shape requirements of the quartz tube 2.

[0031] refer to Figure 1 and Figure 2 The outer surface of the annular inflatable airbag 41 is set as a rough surface. The rough surface setting can increase the friction between the annular inflatable airbag 41 and the outer edge surface of the quartz tube 2 and the inner wall of the embedded groove 43, so that the sealing end cover 1 is firmly fixed to the open end of the quartz tube 2. At the same time, it can also improve the sealing between the sealing end cover 1 and the outer edge surface of the quartz tube 2, and it is not easy to leak during the subsequent air intake processing.

[0032] refer to Figure 1 and Figure 2 Since the temperature of the quartz tube 2 is relatively high during the processing, the sealing end cover 1 is made of stainless steel, and the annular inflatable airbag 41 and the flexible protective layer 5 are made of high-temperature resistant silicone material, which has high heat resistance and is not easily damaged during operation.

[0033] In summary: compared with the existing method of sealing through a sealing plug and fixing and sealing through a high-temperature resistant tape, the processing-assisted molding component of this structure is simple to operate, can be repeatedly recycled, saves costs, and is convenient for processing and manufacturing.

[0034] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
