detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1 and 2, the utility model provides a light-duty caster with a movable side brake with good shockproof effect, including: a fixed plate 1, a bearing seat 2, a connecting rod 3, a mounting plate 4, a sliding sleeve 5, a sliding rod 6, and a spring 7 , installation block 8, rotating shaft 9, roller 10, brake assembly 11, described fixed plate 1 is connected on the main body by bolt, described bearing seat 2 is fixedly connected on the lower end surface of fixed plate 1, described connecting rod 3 The upper end is connected to the inner ring of the bearing seat 2, the mounting plate 4 is fixedly connected to the lower end of the connecting rod 3, the sliding sleeve 5 is fixedly connected to both sides of the mounting plate 4, and the sliding rod 6 is slidably connected in the sliding sleeve 5, The mounting block 8 is fixedly connected to the lower end of the sliding rod 6, the spring 7 is sleeved on the sliding rod 6, and the two ends of the spring 7 are connected with the mounting plate 4 and the mounting block 8, and the two ends of the rotating shaft 9 are fixedly connected to the mounting On block 8, described roller 10 is installed on the rotating shaft 9, and described brake assembly 11 is affixed on the installation block 8, and brake assembly 11 matches with roller 10.

The brake assembly 11 is composed of a strip plate 21, a top block 22, an adjustment bar 23, an insertion rod 24, a limit block 25, and a compression spring 26. The strip plate 21 is fixedly connected to the mounting plate 4, There is a through hole on the strip plate 21, and the adjustment bar 23 is slidably connected on the strip plate 21.
