Description

Technical Field

[0001] This utility model relates to the field of high-temperature fastener technology, specifically to an easily detachable high-temperature fastening pin assembly for a forced heat convection box of a glass tempering furnace. Background Technology

[0002] In the glass tempering process, the forced heat convection chamber plays a crucial role. It accelerates heat transfer, ensuring uniform heating of the glass and thus improving the quality and production efficiency of tempered glass. Currently, the common connection method involves using strong bolts to pass through the heat convection chamber and cover plate, then tightening them with nuts. However, the working temperature inside the glass tempering furnace is usually extremely high, generally ranging from 650℃ to 720℃. Under such high temperatures, prolonged operation can cause high-temperature creep in the metal materials. For bolt and nut connections, high-temperature creep will change the fit precision between the bolt and nut. The originally tightly fitted threads gradually deform, and the friction between the bolt and nut increases sharply, eventually causing the bolt to seize up and become impossible to disassemble.

[0003] According to the authorization announcement number CN205528409U, an easy-to-disassemble high-temperature fastening pin assembly for the forced heat convection box of a glass tempering furnace is disclosed. This assembly fundamentally solves the problem of the connectors used to connect the forced heat convection box and its cover in the glass tempering furnace becoming stuck due to high-temperature creep within the furnace. The assembly includes the forced heat convection box and its cover. The high-temperature pin has a T-shaped head and a locking hole at its lower part. After the high-temperature pin passes through the forced heat convection box and its cover, a high-temperature inclined pin is inserted into the locking hole at the lower part of the high-temperature pin. The advantages are: firstly, the combination of the high-temperature inclined pin and the high-temperature pin ensures that even after prolonged (one year or longer) repeated high-temperature creep, it will not become stuck and cannot be disassembled, allowing for normal disassembly, maintenance, and repair; secondly, installation and disassembly are convenient, quick, and labor-saving; and thirdly, it saves costs, uses less material, and is easy to manufacture.

[0004] However, the above-mentioned device still has shortcomings. Although it is inserted into the box by a T-shaped pin and used in conjunction with the pin, the pin is inside the box, which still makes disassembly and assembly somewhat inconvenient and affects the efficiency of disassembly and assembly of the box.
