[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] This embodiment discloses a chain that prevents breakage, such as Figures 1 to 5 As shown, this utility model has strong anti-fracture performance and includes an inner chain plate 1, an outer chain plate 2, a pin 3, a sleeve 4, and a roller 5. A first reinforcing plate 6 is fixedly provided on one side of the inner chain plate 1, completely covering the inner chain plate 1; a second reinforcing plate 7 is fixedly provided on one side of the outer chain plate 2, completely covering the outer chain plate 2; grooves 8 are provided on both the inner chain plate 1 and the outer chain plate 2; a lubricating oil tank 9 is provided in the groove 8; the lubricating oil tank 9 is connected to an oil outlet pipe 10; the inner chain plate 1 is fixedly connected to the sleeve 4; the outer chain plate 2 is fixedly connected to the pin 3; there is a clearance fit between the pin 3 and the sleeve 4; there is a clearance fit between the roller 5 and the sleeve 4; there is a gap between the roller 5 and the inner chain plate 1.

[0014] By adopting the above technical solution: the first reinforcing plate 6 can increase the strength of the inner chain plate 1, and the second reinforcing plate 7 can increase the strength of the outer chain plate 2, thereby extending the life of the chain under high intensity or long-term operation. The lubricating oil tank 9 contains lubricating oil. When the chain is driven, the oil in the lubricating oil tank 9 can flow out through the oil outlet pipe 10 to lubricate the inner chain plate 1, outer chain plate 2, pin 3, sleeve 4, roller 5, first reinforcing plate 6, and second reinforcing plate 7, thereby preventing the chain from breaking due to excessive friction.

[0015] The inner chain plate 1 is fixedly connected to the sleeve 4, the outer chain plate 2 is fixedly connected to the pin 3, the pin 3 and the sleeve 4 are clearance-fitted, and the roller 5 and the sleeve 4 are clearance-fitted, so that the inner chain plate 1, the first reinforcing plate 6 and the outer chain plate 2 and the second reinforcing plate 7 are flexed to achieve transmission.

[0016] like Figure 1 , Figure 2 As shown, both the inner chain plate 1 and the outer chain plate 2 are provided with mating grooves 11; both the first reinforcing plate 6 and the second reinforcing plate 7 have plate rods 12 that are welded to the mating grooves 11; the inner chain plate 1 is welded to the first reinforcing plate 6; and the outer chain plate 2 is welded to the second reinforcing plate 7.

[0017] By adopting the above technical solution: the plate rod 12 is located in the mating groove 11 and welded to the mating groove 11, thereby increasing the contact area between the inner link plate 1 and the first reinforcing plate 6 and the area between the outer link plate 2 and the second reinforcing plate 7, thus making the connection between the inner link plate 1 and the first reinforcing plate 6 stable and the connection between the outer link plate 2 and the second reinforcing plate 7 stable.

[0018] like Figure 1 As shown, the inner link plate 1 and the first reinforcing plate 6 are provided with a first plate hole 13; the sleeve 4 is located on the first plate hole 13 and is interference-fitted with the first plate hole 13; the outer link plate 2 and the second reinforcing plate 7 are provided with a second plate hole 14; the pin 3 is interference-fitted with the second plate hole 14.

[0019] By adopting the above technical solution: the sleeve 4 is located on the first plate hole 13 opened on the inner link plate 1 and the first reinforcing plate 6 respectively, so that the sleeve 4 is stably connected with the inner link plate 1 and the first reinforcing plate 6; the pin 3 is located on the second plate hole 14 opened on the outer link plate 2 and the second reinforcing plate 7 respectively, so that the pin 3 is stably connected with the outer link plate 2 and the second reinforcing plate 7.

[0020] like Figure 4 As shown, a rotating plate 15 is provided inside the oil outlet pipe 10; the rotating plate 15 is connected to the oil outlet pipe 10 via a hinge; a spring 16 is provided between the oil outlet pipe 10 and the rotating plate 15; a retaining plate 17 is provided on one side of the rotating plate 15.

[0021] like Figure 3 As shown, an inclined platform 18 is provided inside the oil outlet pipe 10; an oil injection hole 19 is provided on the oil outlet pipe 10; and a sealing plug 20 is provided at the oil injection hole 19.

[0022] By adopting the above technical solution: the lubricating oil is located above the inclined platform 18 of the lubricating oil tank 9. When the chain is not rotating, the rotating plate 15 can seal the oil outlet pipe 10, thereby preventing the lubricating oil from being discharged through the oil outlet pipe 10 when the chain is not driving. When the chain is driving, the lubricating oil will roll in the lubricating oil tank 9. The impact force of the lubricating oil causes the rotating plate 15 to flip along the hinge, thereby allowing the lubricating oil to flow out and lubricate the chain, thus preventing the chain from breaking due to excessive friction. The clamping plate 17 can limit the rotating plate 15, preventing the rotating plate 15 from rotating excessively towards the spring 16 side. The chain moves towards the higher side of the inclined platform 18. The inclined platform 18 is set at an angle, which can increase the impact force of the lubricating oil and make it easier for the lubricating oil to push the rotating plate 15 open.

[0023] When it is necessary to add oil to the lubricating oil tank 9, the sealing plug 20 can be pulled out from the oil filling hole 19 to add oil. After the oil is added, the sealing plug 20 is placed in the oil filling hole 19 to prevent the lubricating oil from leaving the lubricating oil tank 9.

[0024] In summary, the present invention has the following beneficial effects: the first reinforcing plate 6, which completely covers the inner chain plate 1 on one side, can improve the strength; the second reinforcing plate 7, which completely covers the outer chain plate 2 on one side, can improve the strength, thereby making the inner chain plate 1 and the outer chain plate 2 strong; when the chain moves, the lubricating oil in the lubricating oil tank 9 flows out through the oil outlet pipe 10 to lubricate the chain and prevent the chain from breaking due to excessive friction.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
