AI Technical Summary
The existing high-temperature endoscopes lack the necessary fixed guidance device, which makes the lens easy to collide with the furnace wall, the length of the extension is large, and a large amount of heat inside is dissipated during use, which can easily burn workers.
A high-temperature endoscope installation structure is designed, including a heating furnace door, a guide mechanism, an endoscope assembly and a shading assembly. The guide mechanism supports and guides the endoscope assembly through components such as the snap ring, a guide tube, a guide seat, a push plate and a knob, and reduces heat spillover through the shading assembly.
The mounting structure effectively supports and guides the endoscope assembly, increasing the lens's protrusion length and observation flexibility, while protecting the safety of the operator by blocking heat spillover.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-temperature furnace accessories, in particular to a high-temperature endoscope installation structure. Background Art
[0002] The portable high-temperature endoscope is a mobile high-temperature kiln internal inspection equipment. It adopts water and air cooling, has a temperature resistance of up to 1800℃, can be extended more than 1 meter into the furnace, and can observe and capture the internal working conditions of the kiln from all directions and angles, providing the most convenient and direct basis for the maintenance of the kiln.
[0003] Since portable high-temperature endoscopes are relatively long, a guide device is generally required to support and guide the outer tube of the endoscope. Existing high-temperature endoscopes lack the necessary fixing and guiding devices, which causes the lens to easily collide with the furnace wall. In addition, the insertion length of the high-temperature endoscope is greatly limited. The use of a guiding and fixing device can extend the lens deep into the furnace. The observation hole on the surface of the furnace door is relatively large, and a large amount of heat is dissipated from the inside during use, which can easily burn workers. Utility Model Content
