[0022] Refer to the attached Figure 2 and the attached Figure 3, this embodiment provides a heat-insulating exposed-frame pressing plate fixing mechanism, including a T-shaped bolt 1. The T-shaped bolt 1 passes through a support frame 2, a column 3, and a pressing plate 4 and is threadedly connected to a locking nut 5. The support frame 2 is provided with a T-shaped groove 100 adapted to the head of the T-shaped bolt 1, and the head of the T-shaped bolt 1 can slide up and down in the T-shaped groove 100. The column 3 is provided with a strip-shaped hole 31 adapted to the rod portion 13 of the T-shaped bolt 1, and the rod portion 13 of the T-shaped bolt 1 can move in the strip-shaped hole 31. The pressing plate 4 is provided with a round hole 41 adapted to the rod portion 13 of the T-shaped bolt 1. In the present utility model, the head of the T-shaped bolt 1 is snapped into the T-shaped groove 100, the rod portion 13 of the T-shaped bolt 1 passes through the strip-shaped hole 31 and the round hole 41, and then the locking nut 5 is screwed on to fix the pressing plate 4 and the column 3 on the support frame 2, and the assembly is simple. In this structural design, neither the round hole 41 nor the strip-shaped hole 31 is a threaded hole, and the processing cost is low; secondly, the combination of the strip-shaped hole 31 and the round hole 41 can reduce the positioning requirements for the holes when opening the holes.

[0023] As another embodiment of the present utility model: A gasket 6 is provided between the locking nut 5 and the pressing plate 4. Specifically, the gasket 6 is a spring gasket.

[0024] As another embodiment of the present utility model: The diameter of the round hole 41 is smaller than the width of the strip-shaped hole 31, and the position of the T-shaped bolt 1 can be adjusted through the strip-shaped hole 31. This structural design is conducive to reducing the positioning requirements for the holes when opening the holes.
