Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example 1: as shown in fig. 1 to 4, a track chain assembly comprises a connecting body 1, a chain clamping groove 2 arranged on the connecting body 1, an inner circular plate 3 arranged at an end of the connecting body 1, an outer circular plate 4, a rotating circular ring 5 sleeved on the inner circular plate 3 and the outer circular plate 4, and a blocking mounting portion 6 for preventing the rotating circular ring 5 from coming off and ensuring the rotating circular ring 5 to rotate, wherein an axial orthographic projection of the rotating circular ring is circular or arc-shaped.

The applicant finds that because the crawler chain assembly parts, the chains and the like are made of metal, see the attached drawing 1, and the drawing shows a schematic connection diagram of the chains A and the assembly parts, the overall weight of the crawler chain assembly parts is heavier, and the installation is laborious, and after the existing protection plates and the connecting parts are connected, friction is generated between the existing protection plates and the tires when the existing protection plates and the connecting parts are used, so that the tires are damaged. Through set up the external mounting hole on the swivel becket, at interior circle arc, the mounting hole in setting up on the excircle arc, outer mounting hole, just can block the installation department installation through the external mounting hole and advance interior mounting hole, in the outer mounting hole, convenience very, time saving and labor saving, also convenient to detach simultaneously, and in the use installation of reality, the connector, swivel becket and chain components of a whole that can function independently mode, can freely assemble the regulation according to the actual demand, very convenient, guard plate structure before for, because guard plate structure is the finished product that the welding finishes in the delivery, in case need adjust, need be interrupted the chain and dismantle, waste time and energy.
