Abstract
The utility model provides a wheel, in particular to caster. The caster comprises a wheel, a foot stand and a shaft and is characterized in that the caster further comprises a caster sleeve, wherein the caster sleeve comprises sleeve sheets and shaft sleeves; the sleeve sheets are connected with the wheel; the shaft sleeves are connected with the sleeve sheets; and the sleeve sheets and the shaft sleeves are mounted on the two sides of the shaft. According to the caster, as the caster sleeve is added, the wheel rubs with the sleeve sheets first when the caster is in use; the sleeve sheets then rub with the shaft sleeves; connecting ring holes are formed in the sleeve sheets to exert effects of oil storage and oil filling; lubrication is improved; rubbing is reduced; the shaft sleeves can promote heat dissipation; and the service life of the caster is prolonged.
Description
Technical field
The utility model relates to a kind of wheel, especially a kind of castor.
Background technology
Castor commonly used is positioned on support by wheel and assembles, and in the time of walking, wheel directly contacts with support, and wheel is because fricative dissipation of heat is slow, and can't lubricate, and is greatly affected the service life of wheel.
Summary of the invention
For the weak point of above-mentioned technology, the utility model provides a kind of castor that can reduce friction.
For achieving the above object, the utility model provides a kind of castor, comprises wheel, foot rest, axle, also comprises a castor cover, and described castor cover comprises nest plate and axle sleeve, nest plate and wheel sub-connection, and axle sleeve is connected with nest plate, and nest plate and axle sleeve all are arranged on the both sides of axle.
Optionally, described nest plate is circular.
Optionally, described nest plate is provided with a chain of hole.
Optionally, the quantity of described castor cover is 2.
Compared with prior art, the utlity model has following advantage:
The castor that the utility model provides, owing to having increased the castor cover, in the time of use wheel first and the nest plate friction, nest plate again with the axle sleeve friction, nest plate is provided with a chain of hole, can play the effect of oil storage and oiling, increases to lubricate, and reduces friction; Axle sleeve can increase heat radiation, increases the service life of castor.
Description of drawings
Fig. 1 is the decomposing schematic representation of castor.
Fig. 2 is the structural representation that installs castor.
Fig. 3 is the section-drawing of A-A face.
Main nomenclature is as follows:
The 1-foot rest; The 2-axle sleeve; The 3-nest plate; The 4-wheel; The 5-axle
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The utility model provides a kind of castor, comprises foot rest 1, wheel 4, axle 5, also comprises a castor cover, and described castor cover comprises nest plate 3 and axle sleeve 2, and nest plate 3 is connected with wheel 4, and axle sleeve 2 is connected with nest plate 3, and nest plate 3 and axle sleeve 2 all are arranged on the both sides of axle 5.
Optionally, described nest plate 3 is circular.
Optionally, described nest plate 3 is provided with a chain of hole.
Optionally, the quantity of described castor cover is 2.
The castor that the utility model provides, owing to having increased the castor cover, in the time of use wheel 4 first and nest plate 3 frictions, nest plate 3 again with axle sleeve 2 frictions, nest plate 3 is provided with a chain of hole, can play the effect of oil storage and oiling, increases to lubricate, and reduces friction; Axle sleeve 2 can increase heat radiation, increases the service life of castor.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
