The induction fixing plate is installed on the shot blasting machine body and can be placed on the shot blasting machine body. Pressure sensor 1 is installed and connected to the inner right side of the low-noise chamber door. When the low-noise chamber door closes, it will drive pressure sensor 1 to press, so that pressure sensor 1 can generate pressure and transmit information to the control box. Then, the control box can control the telescopic closing mechanism to extend and fix it in the induction fixing plate. Pressure sensor 1 is electrically connected to the control box through a connecting wire, and can be controlled accordingly by the control box.

[0041] Reference Figure 1 and Figure 5The low-noise cabin door includes a cabin shell 3. A reinforcing connecting plate 6 is fixed to the outer wall of the cabin shell 3. The reinforcing connecting plate 6 at the outer end of the cabin shell 3 effectively improves the overall strength. An aviation aluminum foil panel 33 is fixed to the middle of the interior of the cabin shell 3. The aviation aluminum foil panel 33 can block sound inside the cabin shell 3. Graphite sound-absorbing baffles 32 located inside the cabin shell 3 are fixed to both sides of the aviation aluminum foil panel 33. The graphite sound-absorbing baffles 32 also have good sound absorption properties. A honeycomb paperboard 31 located inside the cabin shell 3 is fixedly connected to the outer groove of the ink-silent partition 32. The honeycomb paperboard 31 can effectively reduce noise through the honeycomb holes inside. Thus, by utilizing the aviation aluminum foil panel 33, the graphite silent partition 32 and the honeycomb paperboard 31, the cabin shell 3 has a low noise capability as a whole when closed. An opening and closing hinge mechanism is fixedly connected to the left corner of the cabin shell 3 to facilitate opening and closing with the outside.

The closed baffle 4 can be externally installed via screws through the shot blasting machine connecting plate 41. The shot blasting machine connecting plate 41 is installed on the shot blasting machine body via screws. Thus, the closed baffle 4 can be stably placed on the shot blasting machine body through the shot blasting machine connecting plate 41. An induction switch sleeve 42 is fixedly connected to the inner side of the closed baffle 4. The telescopic rod of the electric telescopic cylinder 52 can be inserted into the induction switch sleeve 42 of the closed baffle 4.

[0045] The telescopic rod of the electric telescopic cylinder 52 is positioned corresponding to the sleeve hole of the inductive switch sleeve 42, allowing it to be inserted and fixed accordingly.

[0046] Reference Figure 1 and Figure 4 The opening and closing hinge mechanism includes a welded ear plate 2, which is welded to the outer shell 3 of the hatch and can be stably placed. A positioning sleeve 23 is fixed to the outer end of the welded ear plate 2, which can drive the positioning sleeve 23 for support. A positioning column 22 is sleeved inside the positioning sleeve 23, which can drive the positioning column 22 for placement. The positioning sleeve 23 can be positioned and rotated around the positioning column 22. A connecting end column 21 is fixed to the outer end of the positioning column 22, which can be supported by the connecting end column 21. A connecting ear plate 25 is fixed to the outer wall of the connecting end column 21, which can also be supported by the connecting ear plate 25. A screw mounting plate 24 is fixed to the inner end of the connecting ear plate 25, which can be installed by the screw mounting plate 24. The screw mounting plate 24 is installed on the shot blasting machine body by screws, thus providing stable support.

[0047] Working principle: The low-noise door can be opened and closed on the shot blasting machine body via an opening and closing hinge mechanism. The telescopic closing mechanism can extend and fix the door at the right corner. The induction fixing plate is located outside the telescopic closing mechanism. The telescopic closing mechanism can extend and insert into the induction fixing plate for positioning. When the low-noise door closes, it will drive the pressure sensor 1 to press, thereby generating pressure and transmitting the information to the control box. Then, the control box can control the telescopic closing mechanism to extend and fix itself in the induction fixing plate. When it is inserted into place, the control box will control the audible and visual alarm to stop prompting. This allows personnel to visually check whether it is closed in place, making it more convenient and efficient to use. If it is not inserted into place, the audible and visual alarm will not stop.
