Abstract
The utility model relates to the technical field of universal wheels, in particular to an automatic braking universal wheel which comprises a connecting rotating shaft, an idler wheel support, an axle and an idler wheel. The idler wheel is arranged on the axle in a rotating mode. The axle penetrates through the idler wheel support. The connecting rotating shaft is arranged on the upper portion of the idler wheel support in a rotating mode. An elastic component is connected between the axle and the idler wheel in an abutted mode. The axle is connected with the idler wheel support in a mode of sliding up and down. The automatic braking universal wheel not only is simple and compact in structure and easy to produce, but also can achieve automatic braking, thereby being flexible in use.
Description
Technical field
The utility model relates to the cardan wheel technical field, relates in particular to a kind of self-actuating brake cardan wheel.
Background technology
Cardan wheel is exactly movable castor, and its structure allows horizontal 360-degree rotation in dynamic load or static load.The cardan wheel of prior art generally is designed with brake gear just can realize the function of braking, and the cardan wheel more complicated of this structure manufacture difficulty, and cost compare is high.Brake gear on this cardan wheel need to pass through M/C, and when running into the occasion that needs frequent use, this cardan wheel has used with regard to underaction.
Summary of the invention
The purpose of this utility model is to provide a kind of self-actuating brake cardan wheel for the deficiencies in the prior art, and is not only simple in structure, compact, is convenient to make produce, and can realizes self-actuating brake, uses very flexible.
For achieving the above object, a kind of self-actuating brake cardan wheel of the present utility model, comprise connection rotating shaft, rolling wheel support, wheel shaft and roller, described roller is arranged at described wheel shaft rotationally, described wheel shaft passes described rolling wheel support, described connection rotating shaft is arranged at the top of described rolling wheel support rotationally, and butt has elastic component between described wheel shaft and the described rolling wheel support, and described wheel shaft can slide up and down and be connected in described rolling wheel support.
As preferably, described elastic element is metal spring.
As preferably, an end of described connection rotating shaft is provided with screw thread.
As preferably, the stage casing of described connection rotating shaft is provided with hexagonal nut.
The beneficial effects of the utility model: a kind of self-actuating brake cardan wheel, comprise connection rotating shaft, rolling wheel support, wheel shaft and roller, described roller is arranged at described wheel shaft rotationally, described wheel shaft passes described rolling wheel support, described connection rotating shaft is arranged at the top of described rolling wheel support rotationally, butt has elastic component between described wheel shaft and the described rolling wheel support, and described wheel shaft can slide up and down and be connected in described rolling wheel support; This self-actuating brake cardan wheel is not only simple in structure, compact, is convenient to make produce, and can realizes self-actuating brake, uses very flexible.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Extremely shown in Figure 5 such as Fig. 1, a kind of self-actuating brake cardan wheel of the present utility model, comprise connection rotating shaft 1, rolling wheel support 2, wheel shaft 3 and roller 4, described roller 4 is arranged at described wheel shaft 3 rotationally, described wheel shaft 3 passes described rolling wheel support 2, described connection rotating shaft 1 is arranged at the top of described rolling wheel support 2 rotationally, and butt has elastic component 5 between described wheel shaft 3 and the described rolling wheel support 2, and described wheel shaft 3 can slide up and down and be connected in described rolling wheel support 2.
Described elastic element 5 is metal spring.
One end of described connection rotating shaft 1 is provided with screw thread.
The stage casing of described connection rotating shaft 1 is provided with hexagonal nut.
Self-actuating brake cardan wheel of the present utility model can be realized self-actuating brake by the control of weight, when connection rotating shaft 1 pressurized, pressure is passed to rolling wheel support 2, rolling wheel support 2 extruding elastic elements 5, rolling wheel support 2 drops to ground fits, and rolling wheel support 2 is by realizing self-stopping function with the friction force on ground.
Described elastic element 5 can arrange for different use occasions different dynamics.Self-actuating brake cardan wheel of the present utility model goes for different pulley occasions, the present embodiment is preferred for the laundry machine carriage, can utilize the variation of laundry machine weight to realize the automatic brake functions of laundry machine carriage by the self-actuating brake cardan wheel with the present embodiment.Elastic element 5 can arrange according to the actual weight of laundry machine, for example the weight of laundry machine is 20kg's, elastic element 5 also can be arranged to have the elastic force of 20kg, elastic element 5 can support the weight of laundry machine self, when laundry machine in the course of the work, after being injected into the water of constant weight, when overall weight greater than 20kg, elastic element 5 is fully compressed, rolling wheel support 2 drops to ground fits, rolling wheel support 2 by with the friction self-actuating brake on ground, the laundry machine carriage is firm is fixed on original place, the work that laundry machine can be stable.When laundry machine along with after the water of inside is progressively discharged, the weight of laundry machine alleviates gradually, elastic element 5 also and then recovers gradually, behind rolling wheel support 2 built on stilts, the laundry machine carriage is free to slide.
Self-actuating brake cardan wheel of the present utility model is not only simple in structure, compact, is convenient to make produce, and can realizes self-actuating brake, uses very flexible.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
