Damage, although people are just although some chairs of the prior art are equipped with idler wheel idler wheel and are more flexibly easy to displacement sliding
It is often fallen down when seat；When needing the position to desk or cabinet to be adjusted, need multi agent cooperation that can just move, thus
Inconvenience is brought to the routine use of people.
Summary of the invention
To solve described problem the utility model, to provide a kind of structure simple, easy for installation, be easy to move about the desks and chairs, cabinet and
Noise, labour-saving gravity type is adjustable anti-skidding universal wheel will not be generated.
The technical solution adopted in the utility model:
A kind of adjustable anti-skidding universal wheel of gravity type, including turning rolls, connecting cylinder, spring pressure adjusting knob and spring, institute
Connecting cylinder is stated, inside upper part is provided with threaded portion, and the threaded portion is threadedly coupled with the spring pressure adjusting knob, under inside
Portion is provided with slide groove portion, and the slide groove portion is equipped with the turning rolls slided up and down；
The turning rolls, upper surface are provided with boss, and lower end surface is provided with the universal wheel of rolling；
The spring pressure adjusting knob, upper surface, which is provided with, screws slot, and lower end surface is provided with spring fixing groove, and side wall is set
It is equipped with the screw thread with threaded portion cooperation；
The turning rolls is connect by the spring with the spring pressure adjusting knob, and one end of the spring is set to
In the spring fixing groove, other end clamping is set on the boss.
Further, the slot that screws is one of trough of belt, cross recess and interior hexagonal.
Further, the connecting cylinder lower end surface is fixed with anti-skid washer.
Compared with prior art the utility model has the beneficial effects that the utility model can apply to various furniture especially
More bulky furniture is installed on the support portion of furniture, spring can be configured according to the weight of carried furniture, by adjusting spring
The upper and lower position in connecting cylinder of pressure adjustment knob decreases or increases the size of spring force, is less than the elastic force of spring or greatly
In the weight of carried furniture, when furniture is mobile, as long as will be ejected or be pressed into decreasing or increasing some power universal wheels
Through-hole will not wear furniture when that will not generate noise in pop-up through-hole moving process, when indentation through-hole anti-skid washer can prevent
Displacement and sliding, when being especially mounted to chair, prevent chair to be displaced, personnel are caused to slip while people sits down and stands up.
