PURPOSE:To enhance both the attachment working efficiency and the safety by providing the attachment frames for both the diaphragm and th damper in separation and then combining these frames into a body with screws. CONSTITUTION:Frame 1 is divided into two parts: diaphragm attachment frame 2 and damper attachment frame 3. Frame 2 features a square form with square opening 4 provided inside, and frame 3 features a circular form with opening 5 provided inside each. Concavity 6 is provided at four areas on the back side of frame 2, and support part 7 is provided at four areas on the front side of frame 3 respectively. And concavity 6 is engaged with part 7 each. Then both frames 2 and 3 are screwed into one body via screw 10 which is put in through each screw insertion hole 8 and fixed within each screw hole 9. In such constitution, the unexpected distortion can be avoided to the damper, enhancing greatly the attachment working efficiency. |
