The invention discloses a large simple-pendulum type recreation device. The device comprises a suspending rod, a connection sleeve, a rotary plate, a pendulum shaft and a revolving shaft. One end of the pendulum shaft is connected with a rotary sleeve. The other end of the pendulum shaft is fixed with a pendulum shaft gear. The middle of the pendulum shaft penetrates through a pendulum shaft bearing. The pendulum shaft gear is meshed with a small gear of the pendulum shaft. The pendulum shaft bearing is fixed at the top of a support arm. The support arm is in a tilting structure. The upper endpart of the suspending rod is connected with the rotary sleeve. The lower end part of the suspending rod is connected with the rotary sleeve. A revolving shaft gear is arranged in the connection sleeve and fixed at the upper end part of the revolving shaft. The revolving shaft penetrates out of the connection sleeve. Additionally, the lower end part of the revolving shaft is connected with a central position of the rotary plate. The lower part of the rotary part is equipped with an annular platform, on which a seat is fixed. The revolving shaft gear is meshed with a revolving small gear. Thelarge simple-pendulum type recreation device is advantaged by being good in stability and excellent in safety.

The invention relates to a triple-protection safety seat with telescopic straps and mainly aims to solve the problem that an existing safety seat does not have safety protection measures for pressure bar breakage or pressure bar shaft breakage. The triple-protection safety seat is characterized in that a swing arm (9) is hinged to the backrest of a seat framework (1), the two straps (11) winds around guide wheels (10) and are connected with the swing arm (9), a locking oil cylinder (12) is hinged to a support (19) at the rear of the backrest of the seat framework (1), the oil cylinder rod end of the locking oil cylinder (12) is hinged to the swing arm (9), the locking oil cylinder (12) is a sealed oil cylinder, and an electromagnetic valve (11) and an energy accumulator (14) are serially connected between the rodless cavity and the rod cavity of the oil cylinder. The triple-protection safety seat has the advantages that if the upper half of a pressure bar breaks or a pressure bar shaft breaks, the telescopic straps can still effectively constraint a passenger, passenger safety is guaranteed, and high safety and comfortableness are achieved; the straps can be unfastened and fastened along with the ascending and descending of the pressure bar, and operation simpleness and high automation level are achieved.
