Abstract
The utility model provides an inserting rod bearing movable castor, comprising a support, an inserting rod, an upper bead disk between the upper part of the inserting rod and the upper face of the corresponding part of the support, the upper bead disk comprises a big disk and a steel ball, a ball bearing is installed between the bottom of the support corresponding part and the lower part of the inserting rod; a bearing disk is inlaid in the bottom of the support corresponding part, the ball bearing is installed in the bearing disk, the inner ring of the ball bearing is sleeved on the thin portion of the lower end of the inserting rod, a pad is installed between the inner ring of the ball bearing and the big disk of the upper bead disk; a wheel shaft is disposed at the lower part of the support, a wheel shaft bearing is disposed on the wheel shaft, a wheel is sleeved at the external of the wheel shaft bearing, the inner ring of the wheel is thinner than the outer ring, a wheel cover is installed at the inner ring. The inserting rod bearing moveable castor in the utility model is advantaged by changing the habitual rotation structure form of cooperative rotation of the upper and lower bead disks, changing the lower bead disk to a ball bearing structure to make a cooperative rotation with the upper bead disk, improving precision of castor jumping up and down, and moving left and right, as well as improving load capability. The moveable castor is also advantaged by compact structure, flexible rotation, and reduction of noise.
Description
Technical field
The utility model relates to the indoor mobile thing of using, particularly a kind of indoor moving with thing inserted link bearing movable castor.
Background technology
Movable castor is a lot of indoor moving with must be obligato on the thing.But the general-duty movable castor all is to adopt pearl dish structure up and down at present, directly pack into steel ball independently and to use as bearing, the shell of bearing is then born with the appropriate section of base plate, support and inserted link, these parts are the same with the material of base plate, support and inserted link, as the bearing shell, be that intensity, resistance to abrasion are all not enough far away, this just causes the service life of movable castor generally not high.Because indoor mobile scarcely consistent,, join one again and compare difficulty again again, just directly have influence on indoor mobile service life the service life of movable castor with thing in case gone bad one with the used movable castor of thing.
The utility model content
For remedying above-mentioned deficiency, the utility model provides a kind of inserted link bearing movable castor that uses regular bearing on inserted link.
The utility model inserted link bearing movable castor, comprise support, inserted link, inserted link top and above the support appropriate section between last pearl dish, last pearl is coiled and is made up of deep bid and steel ball, wherein: between support appropriate section bottom surface and inserted link bottom a ball bearing of main shaft is housed.
Described support appropriate section studs with a bearing dish on the bottom surface, and ball bearing of main shaft is installed in the bearing dish, and the inner ring of ball bearing of main shaft is contained in the thin portion of inserted link lower end, between the deep bid of the inner ring of ball bearing of main shaft and last pearl dish the pad that is situated between is housed.
Described support bottom is provided with wheel shaft, and wheel bearing is arranged on the wheel shaft, and wheel bearing is with wheel outward, and the wheel inner ring is thinner than the outer ring, and wheel cap is equipped with at the inner ring place.
The utility model inserted link bearing movable castor has changed customary upper and lower pearl dish and has cooperated the rotational structure form, following pearl dish is changed into ball bearing structure cooperate rotation with last pearl dish, improved that castor is upper and lower beats and left and right mobile precision, improved load-carrying capacity.This compact conformation rotates flexibly, has lowered noise.

Fig. 2 is the front elevation of the utility model inserted link bearing movable castor.
The specific embodiment
Below in conjunction with embodiment the utility model inserted link bearing movable castor is done detailed explanation.
Fig. 1 is the lateral plan of the utility model inserted link bearing movable castor, and Fig. 2 is its front elevation.
The utility model inserted link bearing movable castor, comprise support 5, inserted link 1, inserted link 1 top and above support 5 appropriate sections between last pearl dish, last pearl dish is made up of deep bid 3 and steel ball 4, between support 5 appropriate section bottom surfaces and inserted link 1 bottom a ball bearing of main shaft 7 is housed.Adopted ball bearing of main shaft 7, intensity, resistance to abrasion all head and shoulders above original following pearl dish, prolong the service life of movable castor significantly, bob is littler, rotates more flexibly, precision is higher.
Support studs with a bearing dish 6 on the 5 appropriate section bottom surfaces, and ball bearing of main shaft 7 is installed in the bearing dish 6, and the inner ring of ball bearing of main shaft 7 is contained in the thin portion of inserted link 1 lower end, between the deep bid 3 of the inner ring of ball bearing of main shaft 7 and last pearl dish the pad 2 that is situated between is housed.
Support 5 bottoms are provided with wheel shaft 9, and wheel bearing 10 is arranged on the wheel shaft 9, are with wheel 11 outside the wheel bearing 10, and wheel 11 inner rings are thinner than the outer ring, and wheel cap 8 is equipped with at the inner ring place.
