Embodiment 1
[0022] Such as Figure 1-4 As shown, a safety swing with adjustable speed includes a fixed rod 1 and a swing board 2. The fixed rod 1 can be an ordinary cylindrical steel pipe, and the two ends of the fixed rod 1 can be installed on the ground through fixed brackets. Both sides of the upper end are fixedly connected with a connecting rod 3, the upper end of the connecting rod 3 is rotationally connected with the fixed rod 1, and the upper ends of the two connecting rods 3 are fixedly connected with the same drum 4, and the drum 4 is a cylindrical part sealed at both ends , it should be noted that the drum 4 is filled with lubricating oil (not shown in the figure), the drum 4 is coaxially rotated and sleeved outside the fixed rod 1, and the drum 4 and the fixed rod 1 are sealed and slidably connected, and the inside of the drum 4 Fixedly connected with an annular partition 5, the inner and outer walls of the annular partition 5 are respectively fixedly connected with a first fi...
Embodiment 2
[0026] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that: the left and right sides of the first fixed plate 6 are symmetrically provided with a limit plate 19, the limit plate 19 is fixedly connected with the side wall of the fixed rod 1, and the limit plate A spring 20 is fixedly connected between 19 and the first fixing plate 6 .
[0027] In this embodiment, when the swing board 2 rotates, it will drive the first fixed board 6 to reciprocate left and right along the lower end of the fixed rod 1, and the rotation range of the first fixed board 6 is proportional to the rotation range of the swing board 2. Therefore, by setting the limit plate 19 and the spring 20, the rotation range of the first fixed plate 6 is controlled, thereby, the swing range of the swing board 2 can be controlled, the controllability of the swing is further improved, and the safety of children when playing is increased. sex.
