[0001] This utility model relates to the field of machine tool protective door technology, specifically a machine tool protective door that is easy to disassemble. Background Technology
[0002] The protective door used on CNC machine tools is also known as a sliding door. The installation of the protective door reduces the chance of flying parts from the workpiece causing injury and improves the safety of CNC machine tool use. However, in daily use, the protective door inevitably needs to be disassembled, replaced or repaired.
[0003] When disassembling existing protective doors, it is generally necessary to manually unscrew the screws on the protective door first, and then open the locking foot (limiting structure) on the protective door before disassembly can be achieved. The two steps are time-consuming, and because the screws and locking foot are located between the protective door and the protective door guide rail, the space for the screwdriver to move is relatively narrow, and the disassembly is also difficult. Therefore, the disassembly of the protective door is time-consuming and difficult. To address this, we propose a machine tool protective door that is easy to disassemble. Utility Model Content
