Description
Technical field:
The utility model belongs to a kind of and is installed in furniture, utensil bottom so that mobile caster wheel, and what be specifically related to is a kind of weight-bearing activities castor.
Background technology:
Existing load-bearing castor comprises castor and support, the castor center is provided with a bearing pin, the bearing pin two ends connect support, there is an adapter shaft to be connected on the support with furniture, utensil bottom, on adapter shaft on the support, also be provided with ball thrust bearing, owing to need bear bigger quality, in use, because castor also has divertical motion except that the rotation of self, and the friction force of the horizontal direction that the carrier that can't bear big quality of ball thrust bearing produces, so can cause the easy damage of ball thrust bearing, cause can't using of castor.
Summary of the invention:
At the defective that prior art exists, the purpose of this utility model provides a kind of weight-bearing activities castor that can effectively prevent the castor damage that can overcome above-mentioned defective.
The technical scheme in the invention for solving the technical problem is: a kind of weight-bearing activities castor, described weight-bearing activities castor comprises wheel and support, one bearing pin is set in the middle of the wheel, the bearing pin two ends are connected with support, it is characterized in that described support upper end is connected with a bearing, be connected with a movable disk on the bearing, described movable disk is connected with the interior ring of bearing, the outer shroud setting of described bearing is connected with bearing carrier ring, be connected with the pearl dish on the bearing carrier ring, pearl dish and the steel ball that is provided with thereof and support form the surface bearing structure.
Described movable disk is provided with dustproof projection.
Described castor connecting portion lower end is provided with dustproof groove.
The utility model is rational in infrastructure, can so that on the castor each bearing stressed evenly, improve the service life of load-bearing castor.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
As shown in Figure 1, a kind of weight-bearing activities castor, described weight-bearing activities castor comprises wheel and support 8, in the middle of the wheel bearing pin is set, and the bearing pin two ends are connected with support, it is characterized in that described support 8 upper ends are connected with a bearing 5, be connected with a movable disk 2 on the bearing, described movable disk 2 is connected with the interior ring of bearing 5, and the outer shroud setting of described bearing 5 is connected with bearing carrier ring 7, be connected with pearl dish 3 on the bearing carrier ring 7, pearl dish 3 and the steel ball 4 that is provided with thereof and support 8 form the surface bearing structure.
Described movable disk 2 is provided with dustproof projection.Dustproof projection can prevent effectively that dust from falling into bearing, improves the service life of castor.
Described castor connecting portion 1 lower end is provided with dustproof groove 6.Dustproof groove 6 can prevent effectively that dust from falling into bearing, and it is more smooth and easy that bearing is rotated.
