At present, current fork truck rim is mostly rim, spoke, outer felly or rim, spoke, lock circle and outer felly structure, belongs to two traditional formulas or three-piece structure. For example, patent No. 201020157847.8 describes a three-piece forklift steel ring, which is formed by welding a circular spoke plate on the inner wall of a cylindrical rim body, wherein a clamp spring is arranged in an R-shaped groove at one side end of the rim body, and the clamp spring is connected with a retainer ring; the retainer ring is of an L-shaped structure, although the structure of the wheel rim is simple, the integral strength of the wheel rim is not high, the fixing effect of the clamp spring on the retainer ring is limited, and the problems of deformation, cracks and the like are easily caused in the using process. Therefore, the existing forklift rim structure needs further improvement.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome not enough among the prior art, provide a four formula fork truck rims, have use intensity height, simple to operate, long service life's characteristics, can extensively be used for wheeled engineering machinery vehicle field, especially fork truck field.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a four-piece forklift rim sequentially comprises a retainer ring, a seat ring, a locking ring and a rim body, wherein the rim body is a welded combination of a rim and a spoke; the rim body is provided with a groove, and a locking ring is arranged in the groove; the lock ring is connected with the seat ring and the retainer ring, and the retainer ring presses the seat ring.

As a refinement, the spokes are located inside the rim and are provided with quarter-turn mounting surfaces.

As an improvement, the spoke is provided with an air valve hole and bolt holes which are uniformly distributed according to a circle with the same diameter.

As an improvement, the groove is one of a trapezoid groove, a round groove or an R-shaped groove.

As an improvement, the seat ring is of a reducing structure, and the diameter of the seat ring is gradually increased along the square close to the lock ring.

As an improvement, the top of the seat ring is provided with a matching extension conical surface which is propped against the locking ring.

As an improvement, the retainer ring is provided with a step round platform structure, and the retainer ring is fixed on the lock ring through the step round platform structure.

As an improvement, the lock ring is provided with a slotted hole.

The utility model has the advantages that: the four-piece forklift rim has the characteristics of high use strength, convenience in installation and long service life; by adopting the four-piece structure of the retainer ring, the seat ring, the locking ring and the rim body, the seat ring is sleeved on the rim body and is ejected out of the rim body, and the retainer ring is fixed by the locking ring, so that the installation is more flexible and convenient, and meanwhile, a better matching and fixing effect can be achieved, and the retainer ring is prevented from falling off; the spoke is positioned in the rim, so that the rim body is better supported and enhanced, and the overall strength of the rim body is improved; through designing the seat circle into reducing structure to set up the cooperation and extend the conical surface, further improved the effect of withstanding the lock circle, thereby guarantee the better retaining ring of lock circle.

The utility model discloses a four formula fork truck rims adopts split type structure, and retaining ring, seat circle, lock circle are consecutive, have reduced the processing degree of difficulty of each component, have saved the processing cost, have made things convenient for the installation of rim again simultaneously. Through the use feedback on the forklift, the integral strength of the rim is better, and the service life of the rim is improved to a certain extent.
