Problems solved by technology

[0004] 1. Although the description states that "the so-called brakeable caster with a brake assembly means that the caster can be braked by activating the brake assembly or rolled by releasing the brake assembly", so it does not disclose the application of this structure The brake assembly of the swivel caster, while the brake assembly on the traditional swivel caster is generally installed on the roller, which will move with the rotation of the roller, for example, the application number is 201410227971. Chinese invention patent, so it is impossible to use the transmission shaft to connect the brake components of multiple traditional swivel casters;
[0005] 2. For medical equipment such as hospital beds, it is often necessary to switch the universal casters between directional movement and universal movement, but the universal casters of this structure cannot move directional;
[0006] 3. The traditional pedal drives the brake pads to brake, which is easy to wear the brake pads, which in turn leads to poor braking stability and affects the life of the universal caster

Abstract

The invention provides a universal caster and connecting structure and an adjusting method of the universal caster and connecting structure, and belongs to the field of universal casters. According tothe universal caster and connecting structure and the adjusting method of the universal caster and connecting structure, the problems that existing universal casters cannot brake synchronously and cannot move directionally are solved. The universal caster and connecting structure includes four universal casters and an adjusting frame connected with the four universal casters. Each universal caster includes a turning sleeve, a wheel frame, two rollers, a brake pipe, an adjusting rod and an adjusting column, wherein a fixing sleeve sleeves the top end of the turning sleeve, the wheel frame is fixed to the bottom end of the turning sleeve, the wheel frame includes an inner ring and an outer ring, the two rollers are connected with the wheel rings, the inner ring movably sleeve the wheel rings, the brake pipe is located in the wheel frame, a brake column is arranged in the brake pipe, an adjusting block is fixed to the adjusting rod, an alignment ring is fixed to the inner wall of the fixing sleeve, an adjusting hole is formed in the inner wall of the fixing sleeve, the adjusting column is arranged in the adjusting hole in a perforating mode, and an adjusting groove is formed in the column wall of the adjusting column. According to the universal caster and connecting structure and the adjusting method of the universal caster and connecting structure, the four universal casters areconnected by the adjusting frame, so that the universal casters can be switched among universal movement, directional movement and braking casters synchronously and quickly.

Description

technical field [0001] The invention belongs to the technical field of universal casters, and relates to a universal caster, a connection structure and an adjustment method thereof. Background technique [0002] The bottom of the movable medical equipment will have universal casters. The braking device of the existing universal casters usually adopts brake pads to brake. The brake pads are driven by stepping on the pedal to brake the universal casters. The swivel casters are all independent braking structures, resulting in the need to operate the brakes one by one, and the braking stability is poor. [0003] The existing application number is 201310237343.5, a Chinese invention patent named "caster device", which connects the brake assembly with the brake assembly of the first caster and the second caster, so that the first caster can be controlled by depressing or lifting the main pedal. The combined braking or release of the caster and the second caster, so that the brake...
