A placing frame for processing of middle-transmission light high-insulation float glass
ActiveCN224312267UIntegrity guaranteedQuality assuranceExternal framesContainers to prevent mechanical damageFixed frameAirbag
This utility model discloses a placement frame for processing medium-transmittance, high-heat-insulating float glass, applicable in the field of frames. It includes a shell and an inflatable structure. A fixed frame is welded to the top of the shell, and a first through hole communicating with the fixed frame is opened on the top of the shell. Airbags are installed on opposite sides of the two fixed frames, and second through holes communicating with the airbags are opened on opposite sides of the two fixed frames. A back plate is welded to the top of the shell, and a fixed plate is provided on the front of the back plate. The back plate has a mounting groove on its front. It possesses a collision buffer function, preventing the glass from moving backward too quickly and colliding strongly with the back plate, thus ensuring the integrity and quality of the glass. Simultaneously, it facilitates quick positioning of the glass, not only preventing displacement of the glass during frame movement but also reducing friction between them, offering good flexibility.
