[0002] refer to Figure 5 The present invention is a structural cross-sectional view of an existing outer sleeve 2' welded on the outer edge surface of a quartz tube body 1'. The outer edge surface of the existing quartz tube body 1' is set to be smooth. When the outer sleeve 2' is welded to the quartz tube body 1', it is necessary to first wrap a circle of welding fixtures 3' around the welding position of the quartz tube body 1', and weld the outer sleeve 2' and the quartz tube body 1' by hot-melting the welding fixtures 3' wrapped for the first time. After the first welding is completed, the welding fixtures 3' are wrapped around the first welding position again, and the second welding is performed by hot-melting the welding fixtures 3' wrapped for the second time, thereby completing the welding of the outer sleeve and the quartz tube body 1'. The existing quartz tube structure of this type has the following problems during welding processing: each time the welding fixtures 3' are wrapped and then hot-melted and welded, it takes about 8-10 minutes, and two weldings take 15-20 minutes.

[0026] 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.

[0027] refer to Figure 1 and Figure 2 The utility model provides a quartz tube structure, comprising:

[0028] A quartz tube body 1, wherein a welding positioning portion is arranged on the outer edge surface of the quartz tube body 1;

[0029] An outer sleeve 2, which is wound around the outer edge of the quartz tube body 1 and is located on one side of the welding positioning portion;

[0030] The welding fixture 3 is arranged on the welding positioning part. The welding fixture 3 is used to weld the outer sleeve 2 to the outer edge surface of the quartz tube body 1. The welding fixture 3 includes a first welding part 31 arranged on the outer edge surface of the welding positioning part and a second welding part 32 wound on the outer edge surface of the first welding part 31. The first welding part 31 is formed integrally with the quartz tube body 1. The first welding part 31 is an annular welding protrusion formed by hot-melting the outer edge surface of the quartz tube body 1 and rotating and extruding the quartz tube body 1, so that the hot-melting position of the outer edge surface of the quartz tube body 1 is deformed along the axial direction. The second welding part 32 is an annular welding wire wound on the outer edge surface of the annular welding protrusion, and the annular welding wire is made of quartz material; wherein, the outer edge diameter of the first welding part 31 is larger than the inner diameter of the outer sleeve 2 and smaller than the outer edge diameter of the outer sleeve 2, and the outer edge diameter of the second welding part 32 corresponds to the outer edge diameter of the outer sleeve 2.

[0031] refer to Figure 1 and Figure 2 , by forming the first welding piece 31 and the quartz tube body 1 into an integral shape, when the outer sleeve 2 is welded to the quartz tube body 1, the second welding piece 32 is wound on the first welding piece 31, and then the first welding piece 31 and the second welding piece are directly and simultaneously hot-melted, so as to achieve the purpose of welding the outer sleeve 2 to the outer edge surface of the quartz tube body 1. Compared with the existing method of welding by winding the welding wire twice, the welding method of the welding fixture 3 of this structure can reduce the time of winding the welding wire once, and the outer sleeve 2 can be welded to the quartz tube body 1 by a hot-melt welding method, which saves time and labor and improves welding efficiency. In order to ensure that the quartz tube body 1 and the outer sleeve 2 are coaxially arranged during welding, the quartz tube body 1 and the outer sleeve 2 can be fixed and positioned by the claws, and then the welding fixture 3 is used for welding.

[0032] refer to Figure 3 and Figure 4 , wherein the processing method of the annular welding protrusion on the outer edge surface of the quartz tube body 1 is as follows: firstly, a quartz tube body 1 of a certain length is placed on a lathe, and two ends of the quartz tube body 1 are fixed respectively by two claws on the lathe, wherein one claw is a left claw 4 that can rotate but cannot move laterally, and the other claw is a right claw 5 that can rotate and move laterally, and then the fixed quartz tube body 1 is rotated and squeezed by the lathe, and during the rotation process, the outer edge surface of the hot melt position of the quartz tube body 1 is heated by a high-temperature heating component 6, and during the extrusion process, the hot melt position is deformed to form an annular welding protrusion, wherein the axial deformation distance is controlled by the feed amount of the right claw 5, and when the annular welding protrusion is formed, the length of the quartz tube body 1 just meets the actual length requirement.

[0033] refer to Figure 1The inner diameter of the outer sleeve 2 is larger than the outer diameter of the quartz tube body 1, that is, there is a gap 7 between the inner wall of the outer sleeve 2 and the outer edge surface of the quartz tube body 1. When this quartz tube structure is working, the air pressure between the outer edge surface of the quartz tube body 1 and the outside world can be balanced through the gap 7.

[0034] In summary: the quartz tube structure of this structure is simple to operate during welding, saves time and effort, and improves welding efficiency.
