[0020] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0021] Please refer to Figure 1-4As shown, an embedded oil chain of the utility model comprises an oil chain body; the oil chain body comprises a chain link unit 1, a chain link 2 connected between two adjacent chain link units 1, and a sealing ring 3 for fixing the chain link 2; the chain link unit 1 comprises two chain plates arranged opposite to each other; the chain plate has a pin hole 4 for installing the chain link 2; the pin hole 4 comprises an outer hole section 41 located on the outside, an inner hole section 42 located on the inside, and a limiting step 43 connecting the outer hole section 41 and the inner hole section 42; the chain link 2 has an annular groove 21 located on its circumferential surface; after the chain link 2 is inserted into the pin hole 4, an installation gap is formed between the chain link 2 and the outer hole section 41; the installation gap is connected with the annular groove 21 to form an installation groove; the sealing ring 3 is pressed into the installation groove from the outside of the chain link unit 1. In the actual implementation process, the sealing ring 3 is pressed inward from the outside of the chain link unit 1 into the installation groove and deformed to form an inwardly inclined embedded shape to fill the installation groove, thereby firmly controlling the gap between the chain link 2 and the pin hole 4 within a predetermined range, making the oil chain stable and durable, and achieving the effect of lubrication-free maintenance, avoiding the oil chain from twisting during operation and the axial disengagement of the chain link 2, effectively improving the firmness of the connection of the oil chain, and enabling the embedded oil chain to withstand high-strength, extreme temperature and other working environments. After adding the sealing ring 3, the embedded oil chain can be used in bulldozers and mining machinery, allowing the equipment to operate normally in harsh environments and high-temperature and high-pressure environments, making the embedded oil chain more durable and maintenance-free.

[0022] Optionally, the sealing ring 3 is made of a plastically deformable metal material, which is conducive to pressing the sealing ring 3 into the installation groove and can effectively prevent the sealing ring 3 from being damaged and prevent the chain 2 from being accidentally dislodged.

[0023] Optionally, the limiting step 43 has a guiding slope, which gradually inclines toward the inside of the hole from the outer hole section 41 to the inner hole section 42. In actual implementation, the sealing ring 3 is guided by the guiding slope, so that the pressing process is smoother and more efficient.

[0024] Optionally, the sealing ring 3 has a clamping portion 31 clamped in the installation gap and an embedding portion 32 embedded in the annular clamping groove 21. In actual implementation, the cooperation between the clamping portion and the embedding portion 32 can effectively prevent the chain link 2 from being accidentally disengaged from the chain link 2, thereby effectively improving the stability of the embedded oil chain.

[0025] Optionally, the chain link 2 is interference fit with the inner hole section 42, so that the chain link 2 and the chain sheet are more tightly connected, and the chain link 2 and the chain sheet can be effectively prevented from being separated.

[0026] The sealing ring 3 is suitable for high permeability and high load applications, such as mining, heavy building demolition and waste disposal bulldozer equipment. The purpose of the sealing ring 3 is to tightly lock the chain 2 and the chain plate to avoid the generation of gaps. It is recommended to use the sealing ring 3 in heavy bulldozer equipment such as mining. Large building demolition will generate a large load and affect the twisting of the oil chain and produce axial movement. Even machines equipped with standard limit working tracks or exceeding the standard limit working tracks can be installed with the sealing ring 3 to ensure that the torsional effect on the joint is reduced. The sealing ring 3 uses a plastically deformed metal ring as a mechanical locking element. The sealing ring 3 is pressed between the chain 2 and the chain plate to stabilize the connection at a predetermined gap level. The sealing ring 3 is a new and improved seal, and its material is suitable for extreme working temperature environments.

Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
