The surface of the rubber pressure bottle 702 is squeezed, and the lubricating oil in the rubber pressure bottle 702 will flow out through the holes opened on the surface of the oil outlet pipe 711.

The floating ball 703 and the fixed rod 713 play a role in facilitating the observation of the amount of lubricating oil in the rubber pressure bottle 702, so as to facilitate the workers to confirm whether there is still lubricating oil in the rubber pressure bottle 702.

[0034] like Figure 1 and Figure 5As shown, the tensioning device 8 includes a fixed plate 81, the fixed plate 81 is fixedly connected to the bottom plate 1, a screw rod 86 is threadedly connected to the surface of the fixed plate 81, a limiting groove 82 is provided on the surface of the bottom plate 1, a slider 83 is slidably connected to the inner wall of the limiting groove 82, one end of the screw rod 86 is rotatably connected to the slider 83, a round rod 84 is fixedly connected to the surface of the slider 83, and one end of the round rod 84 is rotatably connected to the third gear 85.

The anti-skid grooves 88 can help the handle 87 to rotate more conveniently, and prevent the staff from slipping when turning the handle 87.

[0035] The overall working principle is that the chain body 6 needs to be protected by the lubrication device 7 when it is running. First, the screw rod 707 is rotated, and the screw rod 707 will drive the arc plate 708 to move, and at the same time drive the guide plate 709 to slide along the surface of the fixed block 706 and the transmission shaft. The guide plate 709 can prevent the arc plate 708 from rotating with the screw rod 707 until the rolling resistance on the arc plate 708 is against the surface of the rubber pressure bottle 702. At this time, when the first transmission shaft 2 and the second transmission shaft 3 are in operation, they will drive the arc and the screw rod 707 and the guide plate 709 to rotate together, and the first transmission shaft 2 and the second transmission shaft 3 will The first gear 4 and the second gear 5 are driven to rotate.

When the rubber pressure bottle 702 is squeezed, the lubricating oil in the rubber pressure bottle 702 will flow out through the holes opened on the surface of the oil outlet pipe 711. Since the sponge has adsorption properties, the sponge sleeve 712 can evenly apply the lubricating oil on the surface of the chain body 6, thereby realizing self- Dynamic lubrication, when the lubricating oil in the rubber pressure bottle 702 flows out, it will drive the float 703 to move, and the movement of the float 703 will drive the fixed rod 713 to slide. The float 703 and the fixed rod 713 play the role of facilitating the observation of the amount of lubricating oil in the rubber pressure bottle 702, so that it is convenient for workers to confirm whether there is still lubricating oil in the rubber pressure bottle 702. When it is necessary to inject lubricating oil, turn the cover 705, and the cover 705 moves with the help of the thread in the infusion tube 704, so that the cover 705 is out of contact with the infusion tube 704. At this time, the lubricating oil can be injected into the rubber pressure bottle 702, and the arc plate 708 is driven to move by the screw 707. The flow rate of the lubricating oil can be controlled by the force with which the arc plate 708 squeezes the rubber pressure bottle 702, thereby improving the lubrication effect of the chain body 6. By setting up the lubricating device 7 and utilizing the mutual cooperation among the L plate 701, the rubber pressure bottle 702, the infusion tube 704, the cover 705, the fixing block 706, the screw 707, the arc plate 708 and the oil outlet pipe 711, the chain body 6 can be automatically smeared with lubricating oil during operation, thereby reducing the degree of wear of the chain body 6, improving the transmission efficiency, making the mechanical equipment run more smoothly, and extending the service life of the chain body 6 and the transmission system, thereby improving the reliability of the equipment.

[0036] When the chain body 6 is used for transmission for a long time, the chain body 6 will easily become loose, and the tensioning device 8 needs to be used to tighten the chain. First, turn the handle 87, and the handle 87 will drive the screw rod 86 to rotate, thereby driving the slider 83 to slide along the inner wall of the limit groove 82. The limit groove 82 has the function of limiting the movement path of the slider 83. The movement of the slider 83 can drive the round rod 84 and the third gear 85 to move, thereby realizing the tensioning of the chain body 6. The surface of the handle 87 is provided with a plurality of anti-skid grooves 88, which can help the handle 87 to rotate more conveniently and avoid working When a person turns the handle 87, there will be no slipping. By setting up the tensioning device 8, the chain body 6 can be effectively tightened by utilizing the cooperation between the fixed and limiting grooves 82, the slider 83, the round rod 84, the third gear 85 and the screw rod 86, which can reduce the wear of the chain body 6 during operation, avoid the chain body 6 being too loose and out of contact with the gear, ensure the close contact between the chain body 6 and other parts, and improve the transmission efficiency. At the same time, the tensioning device 8 can also improve the stability and safety of the mechanical equipment during operation, and ensure the stability and safety of the chain when the equipment is running.
