LINER MOUNTING STRUCTURE AND CRUSHER
Document Type and Number:
Japanese Patent JP2022099729
Kind Code:
A
Abstract:
To provide a liner mounting structure that prevents difficulty in attachment/detachment.SOLUTION: A liner mounting structure 10 comprises a pin 60, a spring 30, and a retaining member 20. The pin 60 is disposed so as to penetrate a first hole 7b formed in a liner 7 and a second hole 2c formed in a casing 2, and has a first head portion 62 that cannot pass through the first hole 7b and a second head portion 63 that is located on the opposite side to the first head portion 62 in an axial direction. The spring 30 is disposed on the opposite side to the liner 7 across the casing 2, and is disposed in parallel with an axial direction of the pin 60. The retaining member 20 is formed with a third hole 22, and by being rotated around its rotation axis of its axial direction, switches between an open state in which the second head portion 63 can pass through the third hole 22 and a lock state in which the second head portion 63 cannot pass through the third hole 22. In the lock state, the second head portion 63 is pressed in a direction separating from the casing 2, by an energizing force received from the spring 30.SELECTED DRAWING: Figure 3
