Abstract
The invention discloses a kind of silent contact roller for market shopping car, including pedestal, brake wheel body and rolling wheel；The side protrusion of the pedestal is provided with two pieces of lugs, and the brake wheel body is arranged between two pieces of lugs, and the rolling wheel is arranged between the lug and the brake wheel body, and a bearing pin passes through the lug, the rolling wheel and the brake wheel body；The bottom of the brake wheel body is provided with brake shoes, and the bottom of the brake shoes is provided with great friction coefficient layer；Socket tube is provided with the middle part of the brake wheel body, the socket tube inwall is provided with Jing Yin cotton layer, and the bearing pin passes through the socket tube.The Jing Yin cotton layer set in a kind of silent contact roller for market shopping car of the present invention, the socket tube using the wheel body that brakes so that will not produce noise because of friction between bearing pin and brake wheel body, while the packing ring reduces bearing pin and the friction noise of rolling wheel.
Description
Technical field
The present invention relates to a kind of roller, more particularly to a kind of silent contact roller for market shopping car.
Background technology
Shopping cart is used in large-scale supermarket or market, and shopping cart is provided with castor, all comfortable and easinesses that just seem,
There is no castor, customer purchase will be no longer light.Heavy duty, also high road sill, varying between chill space and table of the shop,
Everything all proposes high requirement to shopping cart castor.
Customer carries out the movement between floor in market by oblique staircase, and the roller of shopping cart is embedded in oblique staircase table
Just it is difficult to move after in the brake groove in face, so as to make shopping cart avoid sliding on oblique staircase.The roller knot of existing shopping cart
Structure is complicated, connects in defective tightness, motion process and can shake between part, causes noise excessive.
The content of the invention
In order to overcome the shortcoming and deficiency of prior art, the invention discloses a kind of Jing Yin rolling for market shopping car
Wheel, including pedestal, brake wheel body and rolling wheel；The side protrusion of the pedestal is provided with two pieces of lugs, the brake wheel body
It is arranged between two pieces of lugs, the rolling wheel is arranged between the lug and the brake wheel body, a bearing pin passes through institute
State lug, the rolling wheel and the brake wheel body；The bottom of the brake wheel body is provided with brake shoes, the brake shoes
Bottom is provided with great friction coefficient layer；Socket tube is provided with the middle part of the brake wheel body, the socket tube inwall is provided with quiet
Sound cotton layer, the bearing pin passes through the socket tube.
Further, in addition to packing ring, the rolling wheel is provided with the centre bore passed through for the bearing pin, the packing ring
It is arranged in the centre bore.
Further, the medial surface of the centre bore is provided with elastic swelling layer.
Further, the outward flange of the rolling wheel sets elasticity layer.
Further, the outer peripheral elastic layer of the rolling wheel is rubber layer.
Further, the outer surface of the bearing pin sets flexible noise reduction layer.
Further, the elastic noise reduction layer is wavy rubber layer.
Further, the edge of the socket tube is provided with chamfering.
What is set in a kind of silent contact roller for market shopping car of the present invention, the socket tube using the wheel body that brakes is Jing Yin
Cotton layer so that noise will not be produced because of friction between bearing pin and brake wheel body, while the packing ring makes bearing pin and rolling wheel
Friction noise reduces.
In order to more fully understand and implement, the invention will now be described in detail with reference to the accompanying drawings.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Embodiment
Referring to Fig. 1, the invention discloses a kind of silent contact roller for market shopping car, including pedestal 10, brake wheel
Body 20 and rolling wheel 30；The side protrusion of the pedestal 10 is provided with two pieces of lugs 11, and the brake wheel body 20 is arranged on two
Between block lug 11, the rolling wheel 30 is arranged between the lug 11 and the brake wheel body 20, and a bearing pin 12 is passed through
The lug 11, the rolling wheel 30 and the brake wheel body 20；The bottom of the brake wheel body 20 is provided with brake shoes 21,
The bottom of the brake shoes 21 is provided with great friction coefficient layer；The middle part of the brake wheel body 20 is provided with socket tube 31, described
The inwall of socket tube 31 is provided with Jing Yin cotton layer 32, and the bearing pin 12 passes through the socket tube 31.
Also include packing ring 33, the rolling wheel 30 is provided with the centre bore 34 passed through for the bearing pin 12, the packing ring
33 are arranged in the centre bore 34.
The medial surface of the centre bore 34 is provided with elastic swelling layer 41.The outward flange of the rolling wheel 30 is provided with bullet
Property layer 42.The outer peripheral elastic layer 42 of rolling wheel 30 is rubber layer.The outer surface of the bearing pin 12 sets flexible disappear
Sound-absorbing layer 43.The elastic noise reduction layer 43 is wavy rubber layer.The edge of the socket tube 31 is provided with chamfering.
What is set in a kind of silent contact roller for market shopping car of the present invention, the socket tube using the wheel body that brakes is Jing Yin
Cotton layer so that noise will not be produced because of friction between bearing pin and brake wheel body, while the packing ring makes bearing pin and rolling wheel
Friction noise reduces.
The invention is not limited in above-mentioned embodiment, if the various changes or deformation to the present invention do not depart from the present invention
Spirit and scope, if these are changed and deformation belongs within the scope of the claim and equivalent technologies of the present invention, then this hair
It is bright to be also intended to comprising these changes and deform.
