DETAILED DESCRIPTION

[0021] See also Figure 1-Figure 3 , an alloy steel rear hinge structure for a mini loader, comprising:

[0022] The rear articulated seat 1 is made of alloy steel. By making the rear articulated seat 1 of alloy steel, the strength and durability of the rear articulated seat 1 can be improved, and the service life of the mini loader can be effectively extended;

[0023] A pair of reinforcing beams 2 are respectively fixed on the left and right sides of the inner side of the rear hinge seat 1. By arranging the reinforcing beams 2 on the inner side of the rear hinge seat 1, the rear hinge seat 1 can be reinforced;

[0024] A pair of shaft sleeves 3 are respectively fixed through the middle of the front and rear ends of the rear articulated seat 1. The shaft sleeves 3 are used to accommodate the rotating shaft, so as to facilitate the micro loader to use the rear articulated seat 1 for articulated activities;

[0025] The oiling mechanism 4 has a pair of oiling mechanisms 4 and is respectively fixed to the outer ends of the two shaft sleeves 3. The oiling mechanism 4 includes an oiling ring 41, an oiling ball 44 and a ball 46. The oiling ring 41 is fixedly connected to the shaft sleeve 3. The upper end of the inner wall of the oiling ring 41 is provided with a plurality of rolling grooves 45. The ball 46 has a plurality of rolling grooves 45 and is connected to the rolling grooves 45 in a one-to-one rolling manner. The lower part of the oiling ring 41 is provided with an oil storage cavity 42. The oiling ball 44 has a plurality of rolling grooves 45 and is connected to the oil storage cavity 42 in a rolling manner. The upper part of the ball 44 penetrates the upper oil ring 41 and is movably arranged with the upper oil ring 41. The upper outer side of the upper oil ball 44 is movably sleeved with a sealing sleeve 43. The sealing sleeve 43 is embedded and fixed with the inner wall of the upper oil ring 41. When the shaft moves inside the shaft sleeve 3, it moves inside the upper oil ring 41, so that the ball 46 on the upper inner side of the upper oil ring 41 will roll with the shaft, and the upper oil ball 44 on the lower inner side of the upper oil ring 41 will roll with the shaft. The sealing sleeve 43 can improve the sealing between the upper oil ball 44 and the upper oil ring 41.

[0026] A refueling assembly 5, wherein a pair of refueling assemblies 5 are installed one-to-one at the outer end of the oiling mechanism 4, and the refueling assembly 5 is communicated with the oiling mechanism 4. The refueling assembly 5 comprises a refueling pipe 51, a base frame 52, a plugging bead 53 and a spring 54. The refueling pipe 51 is fixed to the upper oil ring 41, and the refueling pipe 51 is communicated with the inside of the oil storage chamber 42. The base frame 52 is fixed to the lower side of the inside of the refueling pipe 51, and the plugging bead 53 is arranged above the base frame 52 and plugged into the upper pipe opening of the refueling pipe 51. The spring 54 is connected between the plugging bead 53 and the base frame 52. A sealing gasket 55 is fixed at the upper end of the inner wall of the refueling pipe 51 and located outside the upper pipe opening. The plugging bead 53 is tightly attached to the sealing gasket 55. By inserting the funnel into the upper pipe opening of the refueling pipe 51 and pushing the funnel open The sealing bead 53 has a pin fixed at the center of the lower pipe opening of the funnel through two side frames, so that the bottom of the funnel will not be blocked by the sealing bead 53. In this way, the sealing bead 53 will move down to squeeze the spring 54, and then pour the lubricating oil from the container containing the lubricating oil into the funnel. In this way, when the lubricating oil enters the filling pipe 51, it will flow into the filling pipe 51 along the outer wall of the sealing bead 53, and then enter the oil storage chamber 42. The lower part of the oiling bead 44 contacts the lubricating oil in the oil storage chamber 42. As the shaft rotates inside the sleeve and the upper oil ring 41, the oiling bead 44 will roll with the shaft. At this time, the oiling bead 44 will apply the lubricating oil in the oil storage chamber 42 to the outside of the shaft, so as to facilitate the application of the lubricating oil. No manual application is required, only manual oiling is required, which improves the maintenance efficiency of the maintenance personnel.
