    摘要： Disclosed is a pneumatic floor spring. The pneumatic floor spring comprises a fixed plate (2). A housing (1) is fixed on the bottom surface of the fixed plate (2),and a bottom cover (15) is arranged on the lower end of the housing (1). A convex rotor (4) is in the housing. The end of the convex rotor penetrates through the fixed plate (2) and is fixed with a rotating shaft (14). The lower end of the convex rotor (4) is mated with a guide base (6). The guide base (6) is vertically provided with guide grooves (7). And the guide grooves (7) match with the interior of the housing (1). A piston (8) is arranged on the bottom of the guide base (6). A supporting plate (11) is arranged inside the housing (11) and the piston (8) penetrates through the supporting plate (11). The piston (8) and the supporting plate (11) are provided with a sealing ring (10). The supporting plate (11), the housing (1) and the bottom cover (15) form a closed gas chamber (13). And the gas chamber is filled with compressed nitrogen gas. The spring has simple structure, convenient mounting effect and high working efficiency, moreover, it occupies less space, reduces production cost, mounting cost and mounting time of the convex rotor. Furthermore, it avoids oil leakage, and ensures rotating eccentric property so as to greatly improve service life.

    摘要： A rotary damper 8 includes a damper body 81 having a cylindrical configuration and a rotor 82 rotatably disposed in the damper body 81. The rotor 82 is non-rotatably connected to an inner link 4 so that the rotor 82 is rotatable together with the inner link 4. Two teeth 8 1 c, 81d constituting a part of a gear are formed in an outer circumferential surface of the damper body 81. A tooth 93 a of a gear member 93 rotatable together with an outer link 5 is engaged with the teeth 81 c, 81d. By this arrangement, the damper body 81 and the rotor 82 can be rotated in opposite directions.
