[0019] A protective ring block 2 is fixed on the surface of the mounting pipe head 11, and the groove wall of the protective ring block 2 is connected to a fixing ring 41 through a spring 24. The outer end of the protective ring block 2 fits the limiting ring plate 4, and the outer end of the fixing ring 41 is connected to the limiting ring plate 4. A protective column 3 is plugged into the side of the limiting ring plate 4 through a plug-in hole 42. The protective column 3 is plug-in-distributed on the outer tube surface of the long-wave infrared heating tube body 1 in a circumferential manner.

[0020] First, the protective ring block 2 is symmetrically installed on the surface of the mounting tube head 11 of the long-wave infrared heating tube body 1, so that the protective column 3 is inserted between the limiting ring plates 4 on the sides of the two groups of protective ring blocks 2. When the long-wave infrared heating tube body 1 is bumped from the outside, the protective column 3 resists the external force and contacts the tube surface of the long-wave infrared heating tube body 1.

[0026] As a preferred embodiment, the plug hole 42 facilitates the installation of the protective column 3 on the outside of the quartz tube surface of the long-wave infrared heating tube body 1, so as to protect the quartz tube surface of the long-wave infrared heating tube body 1 from external impact. The protective column 3 made of polyphenylsulfone plastic has high strength and can withstand external impact, and the protective column 3 adopts transparent polyphenylsulfone plastic, which is convenient for normal penetration of infrared rays. The spring 24 is used to buffer the movement of the support limit ring plate 4, thereby sharing the force received by the protective column 3.

[0027] In this embodiment, the protective ring block 2 , the spring 24 , the limiting ring plate 4 , the fixing ring 41 and the protective column 3 constitute a tube surface protection structure of the long-wave infrared heating tube body 1 .
