Description

A kind of foaming wheel

Technical field

The utility model relates to the wheel that a kind of land slow-moving vehicle uses, the foaming wheel that particularly a kind of hand push universal machine is used.

Background technology

It is directly to take turns foaming on the frame that general foaming is taken turns, and the tire of foaming is molded directly within on the wheel frame, the manufacturing cost height.Because tire is molded directly within on the wheel frame, forms an integral body, therefore, no matter be tire or wheel frame which partly damages, just must change whole foaming wheel, the use cost height, waste is greatly.Granted publication day is on April 13rd, 2005, Granted publication number is CN2691900Y, the applying date is on March 24th, 2004, invention and created name is " improvement of hollow foaming wheel reinforced structure ", a kind of improvement of hollow foaming wheel reinforced structure is disclosed, refer in particular in the wheel body of hollow shape foaming wheel, be coated with the core wheel of arranging in the form of a ring by plural number section section portion, and wheel body can be placed on the wheel frame together with core wheel, simultaneously owing to each section portion that forms core wheel, because of being is the individuality that separates with the wheel frame, and make wheel body, between core wheel and the wheel frame, can finish by assembling mode, and when any component wear, all can disassemble replacing arbitrarily.Its weak point is, be equiped with the formed core wheel of section portion that separates by the plural number section in the wheel body of hollow foaming wheel in advance, assemble cumbersome, time-consuming, thus core wheel that plural number section section portion arranges in the form of a ring and wheel body cause especially easily when being fitted to each other that the operator is because of the human element assembling improvement potential risk that loses reinforced structure fully not in place.And each of core wheel section portion side is provided with spaced hollow-out parts, and the wheel body of foaming wheel is to be made of elastic foam after all, and hollow-out parts has a strong impact on the intensity of foaming wheel, and the use mechanical characteristics life-span of foaming wheel is reduced.

Summary of the invention

The purpose of this utility model is exactly at the deficiencies in the prior art, provides a kind of

For achieving the above object, the utility model adopts following technical scheme:

A kind of utility model foaming wheel comprises wheel cap, core wheel, tire, and wheel core housing is contained in the inside of tire, it is characterized in that: described annular arrangement core wheel is provided with an opening, makes tire form a slotted ring; The section of described core wheel is I shape, and the upper edge of leg is circular arc on the core wheel I shape, and the circular arc of last leg upper edge and the circular arc of tire inside top adapt; At the medianly zygomorphic reinforced rib that is provided with of core wheel I shape waist, reinforced rib is parallel with following leg.

The deformable elastic of the core wheel utilization foaming wheel of open annular is assembled, is changed the wheel subassembly and can realize.The wheel wick feed tire that is the I shape section provides enough bearing forces, auxiliary again with of the support of the medianly zygomorphic reinforced rib of core wheel I shape waist to the cover tire inboard, make the supporting construction of tire more reasonable, the wheel that assembles is full, full, and bearing force and bearing capacity reach requirement; The circular arc of the circular arc of leg upper edge and cover tire inside top adapts and can make tire more full on the core wheel I shape.

Preferably, the left and right sides of described core wheel I shape waist is evenly equipped with the support fin, and an end that supports fin is connected with the reinforced rib of core wheel, and the other end is connected with the last leg or the following leg of the I shape of core wheel.Support fin the last leg of core wheel and reinforced rib and time leg and reinforced rib are connected into a cellular structure respectively, the inner edge that supports fin is connected with the waist of core wheel I shape, the support structure power of this grid type is very strong, can improve the bearing force and the bearing capacity of tire greatly.

Preferably, the wheel face of described wheel cap is provided with locating convex block; The following leg of described core wheel is provided with detent; After the assembling of wheel cap and core wheel, the shape coadaptation mutually of the locating convex block of wheel cap and the detent of core wheel, the locating convex block of wheel cap is corresponding with the position of the detent of core wheel.Locating convex block on the wheel face of wheel cap cooperates with the following leg detent of core wheel, locating convex block is assemblied in the detent, makes the stationkeeping between core wheel and the wheel cap, and core wheel can not gone here and there, reduce the cliding friction between core wheel and the wheel cap, improve wheel single-piece service life.

The beneficial effect of the utility model foaming wheel is, it is low to have overcome hollow foaming wheel intensity, reduce defective and potential quality risk problem service life, adopt the grid type supporting construction, both alleviated the overall weight of core wheel, improved the bearing force of core wheel again, utilized the deformable elastic of the core wheel of open annular and foaming wheel to make assembling, changing of tire accessory convenient cleverly, more stable quality is reliable.
