Background technique

Commonly used standard collar is when being used for carrier rear-wheel spindle, half Electric Pallet Stacks front wheel spindle, half electric pallet carrier-and-stacker rear-wheel spindle and all kinds of diameter and being the axle of 20mm on the market, can there be following problem mostly: thin thickness, easily deviate from the jump ring groove when being subjected to axial force, assembling difficulty is big.

The model utility content

The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of collar is provided, have install simple, easy to make, the characteristics of the low and difficult drop-off of cost.

In order to reach above-mentioned purpose of design, the technical solution adopted in the utility model is as follows:

A kind of collar comprises body, described body loop configuration, and body is provided with opening, and ring is gone up a side relative with opening and is provided with groove in the described body.

Described groove is a cone structure, and the slot opening place is greater than the bottom.

Described bottom portion of groove is the arc-shaped transition structure.

The two ends of described opening are respectively equipped with the installation head.

The beneficial effect of collar described in the utility model is: solved the strength problem of general circlip, the axle card is installed the back and is difficult for deviating from draw-in groove, also can not come off when being subjected to axial force; Simpler and easy in the installation process, only need be pinched with needle-nose pliers one and get final product; The production of part has utilized in the factory leftover pieces of other accessory to make, and has saved raw material, has reduced fabricating cost.
