Abstract:
A cushion, which comprises a housing (10), a flexible body (20), and a movable shaft (30). The housing (10) and the flexible body (20) are cylindrical. The flexible body (20) are open at either extremity. The flexible body (20) is sleeved within the housing (10). The movable shaft (30) is sleeved within the flexible body (20). The movable shaft (30) comprises an integrally connected or integrally formed head portion (31) and a rod body portion (32). The head portion (31) of the movable shaft (30) runs through an extremity of the flexible body (20) and protrudes the flexible body (20) or is embedded at either extremity of the flexible body (20). The rod body portion (32) runs through the other extremity of the flexible body (20) and extends to the outside of the flexible body (20). The size of the rod body portion (32) allows the rod body portion (32) to move within the flexible body (20) in the length direction thereof. The size of the head portion (31) allows the head portion (31) to enter the flexible body (20) but not to escape from the flexible body (20). During impact, the head portion (31) of the movable shaft (30) squeezes the flexible body (20), and because the flexible body (20) is flexible, cushioning is provided, thus implementing the goal of cushioning. The cushion is structurally simple, convenient to use, easy to process and manufacture, and easy to control and has strong practicability.
