[0032] A fixed plate frame 1, a connecting side plate 2 is fixedly provided at the bottom end of the fixed plate frame 1, and a shaft sleeve 3 is fixedly provided at the bottom end of the connecting side plate 2;

[0033] A connecting unit, the connecting unit is arranged at the shaft sleeve 3, and the connecting unit is connected with a lifting lug 6;

[0034] A lubrication unit is used to prevent the connection unit from being worn. The lubrication unit is installed at the connection side plate 2 and can automatically lubricate the pin 5 .

[0035] The connection unit includes balls 4 and a pin 5 . An annular inner cavity is arranged inside the sleeve 3 . A plurality of balls 4 are arranged in the annular inner cavity of the sleeve 3 . The balls 4 are arranged to roll in the annular inner cavity of the sleeve 3 .

[0036] A pin 5 is connected to the center of the shaft sleeve 3 , and the arc surface of the pin 5 is in contact with the ball 4 . The arrangement of the pin 5 and the ball 4 enables the rotation function of the pin 5 to be realized.

[0037] The pin shaft 5 is connected with a lifting ear 6. The rotation function of the pin shaft 5 can realize the swinging function of the lifting ear 6, thereby ensuring the lifting ear to swing back and forth when in use.

[0038] The lifting ear 6 includes a plate body 601 , a connecting sleeve 602 and a protrusion 603 . The connecting sleeves 602 are fixedly provided at both ends of the plate body 601 , and the connecting sleeves 602 are connected to the pin shaft 5 .

[0039] Two protrusions 603 are fixedly provided on the arc surface of one of the connecting sleeves 602 .

[0040] The lubrication unit includes a rubber bag 8, a storage bin 7, a connecting pipe 9 and a delivery pipe 11. The rubber bag 8 is fixedly arranged at the side wall of the inner cavity connected to the side plate 2. The inner cavity of the rubber bag 8 is filled with lubricating oil. One end of the delivery pipe 11 is fixedly connected to the inner cavity of the rubber bag 8. The other end of the delivery pipe 11 extends into the annular inner cavity of the sleeve 3 and is fixedly connected to the sleeve 3.

[0041] The storage bin 7 is fixedly arranged on the fixed plate frame 1 , and the inner cavity of the storage bin 7 is filled with lubricating oil.

[0043] A check valve A10 is installed on the connecting pipe 9, and a check valve B12 is installed on the conveying pipe 11. Through the setting of the lubrication structure, when the lifting ear 6 swings left and right, the plate body 601 at the upper end of the lifting ear 6 can press the rubber bag 8, so that the lubricating oil in the inner cavity of the rubber bag 8 is squeezed and conveyed to the annular inner cavity of the sleeve 3 due to the pressing of the rubber bag 8, so that the ball 4 and the pin 5 are lubricated. In the swinging process, the function of automatic lubrication is realized, thereby reducing wear and tear. It is particularly suitable for long-term use, improves the service life of the lifting ear 6, and avoids damage caused by long-term wear. After the lifting ear 6 returns to its original position after swinging, the rubber bag 8 will automatically expand and recover due to the loss of the pressing effect of the protrusion 603, so that the expansion of the rubber bag 8 automatically absorbs the lubricating oil liquid in the inner cavity of the storage bin 7 through the connecting pipe 9, so as to prepare the lubricating oil liquid for the next lubrication. Through the above technical scheme, the function of automatic lubrication can be realized, which is suitable for popularization and use.
