Problems solved by technology

[0003] The caster bracket of the existing swivel caster bears a large moment in the vertical direction, resulting in an excessive eccentric moment at the hinge joint between the mounting plate and the caster bracket, so its bearing capacity is poor, the wear is serious, easy to damage, and the service life is short
Moreover, the existing universal casters cannot realize automatic braking, and do not have anti-collision functions

Abstract

The invention discloses a universal trundle, and relates to the technical field of trundle devices. The universal trundle comprises a trundle, a trundle support and a mounting plate, the trundle is rotatably mounted in the trundle support, and the top of the trundle support is rotatably connected with the mounting plate through a trundle support rotating shaft; a brake device is arranged at the front end of the trundle support and used for locking the trundle, and an anti-collision sensor is further arranged at the front end of the trundle support; an auxiliary wheel is rotationally installed above the rear end of the trundle support and is perpendicular to the mounting plate, and the top of the auxiliary wheel makes contact with the bottom of the mounting plate; the brake device and the trundle support rotating shaft are connected with a driving device, the driving device is connected with a power supply and a control device, and the anti-collision sensor is connected with the power supply and the control device. The bearing capacity of the universal trundle is improved, and anti-collision and automatic braking can be achieved.

Description

technical field [0001] The invention relates to the technical field of caster devices, in particular to a universal caster. Background technique [0002] Casters are a general term, including movable and fixed casters. Swivel casters are what we call universal casters. Its structure allows 360-degree rotation. Fixed casters have no rotating structure and cannot be rotated. Usually, two types of casters are generally the same. It is used together. For example, the structure of the trolley is two fixed wheels on the front, and two movable swivel casters on the back near the push armrest. [0003] The caster bracket of the existing swivel caster bears a large moment in the vertical direction, resulting in excessive eccentric moment at the hinge joint between the mounting plate and the caster bracket, so its bearing capacity is poor, the wear is serious, easy to damage, and the service life is short. Moreover, the existing universal casters cannot realize automatic braking, and...
