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 load-bearing 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 load-bearing 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 load-bearing castor, include wheel and support, the bottom of support is connected with wheel by a bearing pin, the top that it is characterized in that described support is connected with a swivel mount by a ball bearing of main shaft, the center shaft of ball bearing of main shaft is vertical with horizontal surface, the interior ring of ball bearing of main shaft is connected with swivel mount, the outer shroud of ball bearing of main shaft is connected with support, one swivel mount extension is arranged on the described swivel mount, support is connected with pearl dish, the pearl dish and on the steel ball and the swivel mount extension that have form the surface bearing structure.
Described interior ring and swivel mount junction at ball bearing of main shaft is provided with a cover of dust.
Described support is provided with braking mechanism.
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.
Fig. 2 is another example structure scheme drawing of the utility model.
The specific embodiment:
Extremely shown in Figure 2 as Fig. 1, a kind of load-bearing castor, include wheel and support 1, described support is for falling " Y " shape, the bottom of support 1 is connected with wheel by a bearing pin, the bearing pin two ends connect support 1, the top that it is characterized in that described support 1 is connected with a swivel mount 2 by a ball bearing of main shaft 3, the center shaft of ball bearing of main shaft 3 is vertical with horizontal surface, the interior ring of ball bearing of main shaft is connected with swivel mount, and the outer shroud of ball bearing of main shaft 3 is connected with support, and a swivel mount extension 20 is arranged on the described swivel mount, support 1 is connected with pearl dish 21, pearl dish 21 and on the steel ball 4 and the swivel mount extension 20 that have form the surface bearing structures.
The outer end of described pearl dish 21 is provided with dustproof hook portion.Dustproof hook portion can prevent that too much dust from entering steel ball 4, and it is more smooth that bearing is rotated, and improves castor service life.
Described interior ring and swivel mount junction at ball bearing of main shaft is provided with a cover of dust 5.Can prevent that too much dust from entering ball bearing of main shaft, it is more smooth that bearing is rotated, and improves castor service life.
Described support is provided with braking mechanism 6.Braking mechanism contains one handle, a self-lock rod, a securing rod, connects self-lock rod and securing rod on the one handle, and the securing rod end is provided with brake rubber block, and braking mechanism can make the use control of castor more reasonable.
