When the lifting screw is turned with a tool, the rotation of the lifting screw will cause the outer threaded fixing plate to move, and the movement of the threaded fixing plate will drive the connected limit folding rod and the cut surface rod to move. The cut surface rod contacts the side limit groove of the positioning block, so that the cut surface rod applies pressure to the limit groove, so that the positioning block is completely sunk into the connecting block groove. At this time, the connecting block groove will pull the bearing cover to squeeze the sealing strip close to the sealing groove, so that the sealing groove is completely filled after the sealing strip is compressed, and the gap is filled through the sealing groove. The relative movement of the positioning block and the cut surface rod is used to reduce the gap between the bearing seat and the bearing cover, thereby achieving rapid sealing and improving the sealing effect.

[0009] S1: First, put the bearing parts in from the left and right sides of the bearing seat respectively, and then slide the edge of the bearing parts along the inner wall of the bearing seat to align with the oil groove. At this time, the bearing cover needs to be covered on the side of the bearing seat, and the sealing strip on the side of the bearing cover is aligned with the sealing groove. In addition, the positioning block on the side of the bearing cover will also be connected to the connecting block groove accordingly;

[0013] S5: When the pressure ring shrinks into the pressure ring, the lubricating oil in the pressure ring groove will be squeezed out from the small hole on the side of the pressure ring by the pressure ring, and the squeezed lubricating oil will flow into the oil lubrication groove, and lubricate the bearing part through the lubricating oil in the oil lubrication groove, thereby reducing the wear loss of the bearing part during rotation through lubrication;

[0014] S6: Finally, before installing the bearing cover to the bearing seat, insert the mounting rod into the mounting hole, align the through-piece groove in the mounting hole with the limiting piece groove on the side of the mounting rod, and let the limiting folding rod drive the connected limiting angle piece to extend out of the through-piece groove, and the limiting angle piece is clamped in the limiting piece groove to limit the mounting rod, lay the bearing seat flat through the mounting rod, and fix the external device of the bearing seat with the nut;

[0017] The present invention is provided with a sealing groove, a mounting hole, a connecting block groove, a sliding rod groove, a limiting folding rod, a threaded fixing plate, a lifting screw, and a cut surface rod. The connecting block groove pulls the bearing cover to squeeze the sealing strip close to the sealing groove, so that the sealing groove is completely filled after the sealing strip is compressed. The gap is filled by the sealing groove, and the relative movement of the positioning block and the cut surface rod is used to reduce the gap between the bearing seat and the bearing cover, thereby achieving rapid sealing and improving the sealing effect. By rotating the lifting screw, the bearing seat is pressed and sealed all around, and the structural engagement is used to achieve rapid fixing, which is convenient for maintenance, disassembly and replacement.

[0018] The present invention is provided with an oil delivery port, an oil bin ring groove, a connecting groove, a pressure ring, a pressure ring, a reset rubber ring, and a pressure ring groove. The reset rubber ring is raised to fill the contact gap between the pressure ring and the bearing seat, thereby further improving the sealing effect between the bearing seat and the bearing cover. At the same time, when the pressure ring is contracted into the pressure ring, the lubricating oil in the pressure ring groove is squeezed out from the small hole on the side of the pressure ring by the pressure ring, and the squeezed lubricating oil flows into the oil lubrication groove, and the bearing part is lubricated by the lubricating oil in the oil lubrication groove, thereby reducing the wear and loss of the bearing part during the rotation process through lubrication, thereby improving the service life of the bearing part, and maintaining the bearing through lubrication to prevent the bearing from being damaged due to excessive wear;

[0019] The present invention is provided with an installation rod, a limiting plate groove, a limiting angle plate, a through-plate groove, a connecting seat limiting plate, and a connecting seat insertion hole.

After passing through the interior, the seat limiting plate 75 slides from the inside of the bearing seat 1 to the inside of the seat insertion hole 76, and the installation rod 71 is limited by the limiting angle plate 73 clamping the limiting plate groove 72. The bearing seat 1 can be placed flat by the installation rod 71, and the external device of the bearing seat 1 can be fixed by the nut. At the same time, when the bearing seat 1 is placed upright for installation, the seat insertion hole 76 is connected to the installation rod 71 on the external device, and the seat limiting plate 75 is driven by the limiting folding rod 55 to clamp the above-mentioned installation rod 71, thereby realizing the rapid installation and positioning of the bearing seat 1 and other external devices in the structure, saving installation time and facilitating disassembly.

[0032] Working principle: After the bearing component 4 is placed from the left and right sides of the bearing seat 1 respectively, the edge of the bearing component 4 slides along the inner wall of the bearing seat 1 and is aligned with the oil groove 8. At this time, the bearing cover 21 needs to be covered on the side of the bearing seat 1, and the sealing strip 22 on the side of the bearing cover 21 is used to align with the sealing groove 51. In addition, the positioning block 23 on the side of the bearing cover 21 will also be connected to the connecting block groove 53 accordingly. When the lifting screw 57 is rotated with a tool, the rotation of the lifting screw 57 will cause the outer threaded fixing plate 56 to move, and the movement of the threaded fixing plate 56 drives the connected limit folding rod 55 and the cutting rod 58 to move, and the cutting rod 58 contacts the side limit of the positioning block 23 The groove 24 is formed by the cut surface rod 58, so that the positioning block 23 is completely sunk into the connecting block groove 53. At this time, the connecting block groove 53 pulls the bearing cover 21 to squeeze the sealing strip 22 close to the sealing groove 51, so that the sealing groove 51 is completely filled after the sealing strip 22 is compressed. The gap is filled by the sealing groove 51, and the relative movement of the positioning block 23 and the cut surface rod 58 is used to reduce the gap between the bearing seat 1 and the bearing cover 21, so as to achieve rapid sealing and improve the sealing effect. By rotating the lifting screw 57, the bearing seat 1 is pressurized and sealed all around, and the structural engagement is used to achieve rapid fixation, which is convenient for maintenance, disassembly and replacement;

[0033] When the bearing cover 21 is placed on the side of the bearing seat 1, the side cover 3 connected to the bearing cover 21 also moves with it. Before that, it is necessary to fill the oil delivery port 61 with lubricating oil, so that the lubricating oil enters the oil bin ring groove 62 along the oil delivery port 61, and then moves to the connecting groove 63 through the oil bin ring groove 62. Subsequently, the lubricating oil in the connecting groove 63 passes through the pressure ring 64 and enters the pressure ring groove 67 in the pressure ring 65. When the pressure ring 65 is partially placed into the bearing seat 1 along with the movement of the side cover 3, the pressure ring 65 contacts the inner wall of the bearing seat 1. As the lifting screw 57 is turned, the bearing seat 1 and the bearing cover 21 approach each other. At this time, the pressure ring 65 begins to be pressurized. When the pressure ring 64 shrinks into the pressure ring 65 , the reset rubber ring 66 begins to deform and bulge under the force, and the bulge of the reset rubber ring 66 contacts the inner wall of the bearing seat 1, and the reset rubber ring 66 is deformed and bulged to fill the contact gap between the pressure ring 64 and the bearing seat 1, so as to further improve the sealing effect between the bearing seat 1 and the bearing cover 21. At the same time, when the pressure ring 64 shrinks into the pressure ring 65, the lubricating oil in the pressure ring groove 67 will be squeezed out from the small hole on the side of the pressure ring 65 by the pressure of the pressure ring 64, and the squeezed lubricating oil will flow into the oil groove 8, and the bearing component 4 will be lubricated by the lubricating oil in the oil groove 8, so as to reduce the wear and loss of the bearing component 4 during the rotation process through lubrication, so as to improve the service life of the bearing component 4, and maintain the bearing through lubrication to prevent the bearing from being damaged due to excessive wear;

[0034] When the locking cam 75 is in the locked state, the locking cam 73 is locked to the locking cam 76, and the locking cam 76 is in the locked state.

At this time, the bearing cover 21 needs to be covered on the side of the bearing seat 1, and the sealing strip 22 on the side of the bearing cover 21 is aligned with the sealing groove 51. In addition, the positioning block 23 on the side of the bearing cover 21 will also be connected to the connecting block groove 53 accordingly;

[0037] S2: Subsequently, the lifting screw 57 rotates to move the outer threaded fixing plate 56, and then the cut surface rod 58 contacts the side limiting groove 24 of the positioning block 23, so that the cut surface rod 58 applies pressure to the limiting groove 24, so that the positioning block 23 is completely sunk into the connecting block groove 53. At this time, the connecting block groove 53 pulls the bearing cover 21 to squeeze the sealing strip 22 close to the sealing groove 51, so that the sealing groove 51 is completely filled after the sealing strip 22 is compressed, and the gap is filled through the sealing groove 51, and the relative movement of the positioning block 23 and the cut surface rod 58 is used to reduce the gap between the bearing seat 1 and the bearing cover 21, thereby achieving rapid sealing;

[0038] S3: Then, when the bearing cover 21 is placed on the side of the bearing seat 1, the side cover 3 connected to the bearing cover 21 also moves with it. Before that, lubricating oil needs to be filled into the oil delivery port 61, so that the lubricating oil flows into the oil bin ring groove 62 along the oil delivery port 61, and then moves into the connecting groove 63 through the oil bin ring groove 62. Then, the lubricating oil in the connecting groove 63 passes through the pressure ring 64 and enters the pressure ring groove 67 in the pressure ring 65.

[0039] S4: Afterwards, when the pressure ring 65 is partially put into the bearing seat 1 along with the movement of the side cover 3, the pressure ring 65 contacts the inner wall of the bearing seat 1. As the lifting screw 57 is turned, when the pressure ring 64 shrinks into the pressure ring 65, the raised part of the reset rubber ring 66 contacts the inner wall of the bearing seat 1, and the reset rubber ring 66 is deformed and raised to fill the contact gap between the pressure ring 64 and the bearing seat 1.
