Embodiment 1
[0032] The caster 3 is a fixed caster 3, and the fixed caster 3 includes a wheel plate 8 fixedly mounted on the side plate 2 and a pulley 9 rotatably connected with the wheel plate 8; the braking member is a friction belt 10 , the friction belt 10 is fixedly installed on the bottom end of the pull rod 5, the friction belt 10 is compatible with the pulley 9; the bottom of the side plate 2 is provided with a chute 11, and the friction belt 10 and the The chute 11 is compatible. When the pull handrail is not drawn out, the friction belt 10 is in contact with the pulley 9 under the action of the pull rod 5, and the friction force between the friction belt 10 and the pulley 9 is used to brake the pulley 9, so as to avoid necessary friction on the learning table. Displacement; when pulling out the handrail, the friction belt 10 enters the chute 11 of the side plate 2 under the drive of the pull rod 5, the friction belt 10 is separated from the pulley 9, and the pulley 9 can realize ...
Embodiment 2
[0041] The caster 3 is a movable caster 3, and the movable caster 3 includes a mounting plate 12 fixedly connected to the side plate 2, a wheel seat 13 rotatably connected to the mounting plate 12, and a wheel seat 13 rotatably connected to the wheel seat 13. Pulley 9; telescopic rod 14 is fixedly installed on the wheel seat 13, and the brake member is a friction belt 10, and the friction belt 10 is fixedly installed at the end of the telescopic rod 14, and the friction belt 10 and the pulley 9; the mounting plate 12 and the wheel base 13 are provided with through holes, and the pull rod 5 passes through the through holes and is arranged corresponding to the friction belt 10 . When the pull handrail is not pulled out, under the action of the pull rod 5, the telescopic rod 14 is in a stretched state, the friction belt 10 is in contact with the pulley 9, and the pulley 9 is in a braking state; when the pull handle is pulled out, the pull rod 5 is lifted, The telescopic rod 14 co...
