At the same time, the damping arc block contacts the pressure-bearing rubber ring to increase the contact friction, which plays a secondary buffering role and further improves the buffering effect. At the same time, the pressure ring and the pressure-bearing rubber ring slide against each other, reducing the internal space between the pressure ring and the pressure-bearing rubber ring, allowing the pressure oil between the pressure ring and the pressure-bearing rubber ring to enter the middle of the rubber gasket. At this time, the pressure ring squeezes the rubber gasket through the pressure rod above and the pressure rod under the top seat plate, so that the buffer sheet in the rubber gasket is compressed in the middle to make the two sides tilt up, and the pressure oil passes through the gap between the buffer sheets and enters the lubricating groove through the tilting. After the rubber gasket recovers, the pressure oil in the lubricating groove is retained in the lubricating groove, and the rubber gasket, the pressure ring and the pressure-bearing rubber ring are protected by the lubricating groove to prevent the above-mentioned rubber material structure from oxidation and make it elastic, thereby improving the service life of the rubber structure.

At the same time, the structure between the pressure ring and the pressure-bearing rubber ring contracts, so that the internal pressure oil enters the cavity plate through the bottom outer groove, and enters the branch end through the cavity plate, and emerges through the small holes on the side through the screw perforation on the branch end. Due to the liquid tension, the small holes on the side of the screw perforation will only emerge from the small holes on the side of the screw perforation through the branch end when the pressure ring and the pressure-bearing rubber ring contract. The bolt parts are lubricated by the emerging pressure oil to prevent the bolts in the screw perforation from oxidation and rust.
[0010] A shock absorbing method for a highway bridge shock absorbing bearing comprises the following steps:
[0011] S1: The downward movement of the upper end shell will push the pressure plate to move downward to squeeze the top surface of the rubber arch block, and through the pressure plate, the pressure plate fits the inside of the lower end shell through the supporting corrugated plate, and contacts the top surface of the side block after pressing down through the downward pressing square column, which plays a role of pressure positioning on the side block, preventing the rubber arch block from deviating to the center of the lower end shell;
[0012] S2: When the top seat plate is pressed downward, the lower seat end shell uses the top of the rubber arch block as the force point. After the top of the rubber arch block is pressed, the pressure will be transmitted from the middle to the end through the arc-shaped rubber arch block, and the side blocks of the arc-shaped rubber arch block will contact the lower seat end shell, so as to decompose the pressure after the top of the rubber arch block is pressed, and the elastic material will buffer the force;
[0013] S3: In addition, the top of the rubber arch block will be pressed downward to squeeze the contact position of the connected cross arch block, and part of the force on the rubber arch block will be directed downward, so that the cross arch block and the rubber arch block can be compressed and contracted together to improve the buffering effect and prevent the rubber arch block from deforming too quickly after being compressed;
[0014] S4: Subsequently, when the top seat plate is under pressure, it pushes the connected upper seat end shell downward toward the lower seat end shell, and allows the pressure ring in the upper seat end shell to contact the arc surface of the cross arch block downward, so that the bottom of the pressure ring shrinks inward. At the same time, the damping arc block connected to the pressure ring contacts the lower pressure-bearing rubber ring through the bottom arc, so that the damping arc block squeezes the top of the pressure-bearing rubber ring to expand outward, thereby improving the buffering effect through the friction between the pressure ring and the cross arch block and the rubber deformation material;
[0015] S5: Afterwards, the pressure ring and the pressure-bearing rubber ring slide against each other, reducing the internal space between the pressure ring and the pressure-bearing rubber ring, allowing the pressure oil between the pressure ring and the pressure-bearing rubber ring to enter the middle of the rubber gasket. At this time, the pressure ring squeezes the rubber gasket through the pressure rod above and the pressure rod below the top seat plate, so that the buffer sheet in the rubber gasket is pressed in the middle to make the two sides tilt up, and the pressure oil enters the lubricating groove through the gap between the buffer sheets through the tilting. After the rubber gasket is restored, the pressure oil in the lubricating groove is retained in the lubricating groove, and the rubber gasket, the pressure ring and the pressure-bearing rubber ring are protected by the lubricating groove, so as to prevent the above-mentioned rubber material structure from oxidation and make it elastic, thereby improving the service life of the rubber structure;
[0016] S6: When the top seat plate and the base plate are close to each other, the ball joint solid block connected to the bottom hinge seat squeezes the lower connecting rod close to the upper connecting rod through the spherical joint, and the contraction of the lower connecting rod and the upper connecting rod is used to provide support and guidance for the support of the lower seat end shell and the upper seat end shell, so as to prevent the pressure ring and the pressure-bearing rubber ring from being offset by force;
[0017] S7: Finally, the structure between the pressure ring and the pressure-bearing rubber ring contracts, so that the internal pressure oil enters the cavity plate through the outer groove of the bottom through-hole, and enters the branch end through the cavity plate, and emerges through the small holes on the side through the screw perforation on the branch end. Due to the liquid tension, the small holes on the side of the screw perforation will only emerge from the small holes on the side of the screw perforation through the branch end when the pressure ring and the pressure-bearing rubber ring contract. The bolt parts are lubricated by the emerging pressure oil to prevent oxidation and rust of the bolts in the screw perforation.

In addition, the top of the rubber arch block is pressed downward to press the contact position of the connected cross arch block, and a part of the force received by the rubber arch block is guided downward. The cross arch block and the rubber arch block are compressed and contracted together to improve the buffering effect, prevent the rubber arch block from deforming too quickly after being compressed, and improve the buffering effect.
[0020] The present invention is provided with an upper seat end shell, a pressure rod, a rubber gasket, a lubricating groove, a pressure ring, and a damping arc block. The friction force between the pressure ring and the cross arch block cooperates with the rubber deformation material to improve the buffering effect. At the same time, the buffer sheet in the rubber gasket is pressed in the middle to make the two sides tilt up. The pressure oil enters the lubricating groove through the gap between the buffer sheets through the tilting. After the rubber gasket is restored, the pressure oil in the lubricating groove is retained in the lubricating groove. The rubber gasket, the pressure ring, and the pressure-bearing rubber ring are protected by the lubricating groove, so that the above-mentioned rubber material structure is prevented from oxidation to make it elastic, thereby improving the service life of the rubber structure.
[0021] The present invention prevents the pressure ring and the pressure-bearing rubber ring from being offset by force by providing a cavity plate, a branch end, a screw through hole, and a bottom through outer groove. At the same time, the small holes on the side of the screw through hole will only emerge from the small holes on the side of the screw through the branch end when the pressure ring and the pressure-bearing rubber ring are contracted. The bolt components are lubricated by the emergent pressure oil, preventing the bolts in the screw through hole from oxidation and rust. BRIEF DESCRIPTION OF THE DRAWINGS

The bolt parts are lubricated by the emerging pressure oil to prevent the bolts in the screw through hole 63 from oxidation and rust.
[0039] Working principle: When the top seat plate 5 is pressed downward, the lower seat end shell 21 uses the top of the rubber arch block 22 as the force point. After the top of the rubber arch block 22 is pressed, the pressure will be transmitted from the middle to the end through the arc-shaped rubber arch block 22, and the side block 25 of the arc-shaped rubber arch block 22 will contact the lower seat end shell 21, so as to decompose the pressure after the top of the rubber arch block 22 is pressed, and the force received is buffered by the elastic material. In addition, the top of the rubber arch block 22 is pressed downward to squeeze the contact position of the connected cross arch block 23, and part of the force received by the rubber arch block 22 is transferred downward. The cross arch block 23 and the rubber arch block 22 are compressed and contracted together to improve the buffering effect, prevent the rubber arch block 22 from deforming too quickly after being compressed, and improve the buffering effect. At the same time, the downward movement of the upper seat end shell 41 will push the pressure plate 71 to move downward to squeeze the top surface of the rubber arch block 22, and squeeze through the pressure plate 71. The pressure plate 71 fits the inside of the lower seat end shell 21 through the supporting corrugated plate 72, and contacts the top surface of the side sticker 25 after pressing down through the downward pressing square column 73, which plays a role of pressure positioning on the side sticker 25, preventing the rubber arch block 22 from deviating from the center of the lower seat end shell 21;
[0040] When the top seat plate 5 is under pressure, it will push the connected upper seat end shell 41 downward to approach the lower seat end shell 21, and make the pressure ring 46 in the upper seat end shell 41 contact the arc surface of the cross arch block 23 downward, so that the bottom of the pressure ring 46 shrinks inward. At the same time, the damping arc block 47 connected to the pressure ring 46 contacts the lower pressure-bearing rubber ring 24 through the bottom arc, so that the damping arc block 47 squeezes the top of the pressure-bearing rubber ring 24 to expand outward, thereby improving the buffering effect through the friction between the pressure ring 46 and the cross arch block 23 and the rubber deformation material. At the same time, the damping arc block 47 contacts the pressure-bearing rubber ring 24 to increase the contact friction, play a secondary buffering role, and further improve the buffering effect. At the same time, the pressure ring 46 and the pressure-bearing rubber ring 24 slide against each other to reduce The internal space between the pressure ring 46 and the pressure-bearing rubber ring 24 allows the pressure oil between the pressure ring 46 and the pressure-bearing rubber ring 24 to enter the middle of the rubber gasket 43. At this time, the pressure ring 46 squeezes the rubber gasket 43 together with the pressure rod 42 above and the pressure rod 42 below the top seat plate 5, so that the buffer sheet in the rubber gasket 43 is pressed in the middle to make the two sides tilt up, and the pressure oil enters the lubricating groove 44 through the gap between the buffer sheets through the tilting. After the rubber gasket 43 is restored, the pressure oil in the lubricating groove 44 is retained in the lubricating groove 44, and the rubber gasket 43, the pressure ring 46 and the pressure-bearing rubber ring 24 are protected by the lubricating groove 44, so as to prevent the above-mentioned rubber material structure from oxidation and make it elastic, thereby improving the service life of the rubber structure;
[0041] When the top seat plate 5 approaches the base plate 1, the ball joint solid block 82 connected to the bottom hinge seat 81 squeezes the lower connecting rod 84 close to the upper connecting rod 85 through the spherical joint 83, and the contraction of the lower connecting rod 84 and the upper connecting rod 85 provides support and guidance for the support of the lower seat end shell 21 and the upper seat end shell 41 to prevent the pressure ring 46 and the pressure-bearing rubber ring 24 from being force-displaced. At the same time, the structure between the pressure ring 46 and the pressure-bearing rubber ring 24 contracts, so that the internal pressure oil enters the cavity plate 61 through the bottom outer groove 64, and enters the branch end 62 through the cavity plate 61, and emerges through the small holes on the side through the screw through hole 63 on the branch end 62. Due to the liquid tension, the small holes on the side of the screw through hole 63 will only emerge from the small holes on the side of the screw through hole 63 through the branch end 62 when the pressure ring 46 and the pressure-bearing rubber ring 24 contract. The bolt components are lubricated by the emerging pressure oil to prevent the bolts in the screw through hole 63 from oxidation and rust.
[0042] A shock absorbing method for a highway bridge shock absorbing bearing comprises the following steps:
[0043] S1: The downward movement of the upper seat end shell 41 will push the pressure plate 71 to move downward to squeeze the top surface of the rubber arch block 22, and through the pressure plate 71, the pressure plate 71 is pressed against the inside of the lower seat end shell 21 through the supporting corrugated plate 72, and contacts the top surface of the side block 25 after pressing down through the pressing square column 73, which plays a role of pressurizing and positioning the side block 25, preventing the rubber arch block 22 from deviating from the center of the lower seat end shell 21;
[0044] S2: When the top seat plate 5 is pressed downward, the lower seat end shell 21 uses the top of the rubber arch block 22 as a force point. After the top of the rubber arch block 22 is pressed, the pressure is transmitted from the middle to the end through the arc-shaped rubber arch block 22, and the side blocks 25 of the arc-shaped rubber arch block 22 contact the lower seat end shell 21, so that the pressure is decomposed by using the top of the rubber arch block 22 to buffer the force received through the elastic material;
[0045] S3: In addition, the top of the rubber arch block 22 is compressed downward to press the contact position of the connected cross arch block 23, and guide part of the force on the rubber arch block 22 downward, so that the cross arch block 23 and the rubber arch block 22 are compressed and contracted together to improve the buffering effect, and prevent the rubber arch block 22 from deforming too quickly after being compressed;
[0046] S4: Subsequently, when the top seat plate 5 is under pressure, it pushes the connected upper seat end shell 41 downward to approach the lower seat end shell 21, and allows the pressure ring 46 in the upper seat end shell 41 to contact the arc surface of the cross arch block 23 downward, so that the bottom of the pressure ring 46 shrinks inward. At the same time, the damping arc block 47 connected to the pressure ring 46 contacts the lower pressure-bearing rubber ring 24 through the bottom arc, so that the damping arc block 47 squeezes the top of the pressure-bearing rubber ring 24 to expand outward, thereby improving the buffering effect through the friction between the pressure ring 46 and the cross arch block 23 and the rubber deformation material;
[0047] S5: Afterwards, the pressure ring 46 and the pressure-bearing rubber ring 24 slide against each other, reducing the internal space between the pressure ring 46 and the pressure-bearing rubber ring 24, allowing the pressure oil between the pressure ring 46 and the pressure-bearing rubber ring 24 to enter the middle of the rubber gasket 43. At this time, the pressure ring 46 squeezes the rubber gasket 43 together with the pressure rod 42 above and the pressure rod 42 below the top seat plate 5, so that the buffer sheet in the rubber gasket 43 is compressed in the middle to make the two sides tilt up, and the pressure oil enters the lubricating groove 44 through the gap between the buffer sheets through the tilting. After the rubber gasket 43 is restored, the pressure oil in the lubricating groove 44 is retained in the lubricating groove 44, and the rubber gasket 43, the pressure ring 46 and the pressure-bearing rubber ring 24 are protected by the lubricating groove 44, so as to prevent the above-mentioned rubber material structure from oxidation and make it elastic, thereby improving the service life of the rubber structure;
[0048] S6: When the top seat plate 5 and the base plate 1 are close to each other, the ball joint fixed block 82 connected to the bottom hinge seat 81 squeezes the lower connecting rod 84 to approach the upper connecting rod 85 through the spherical joint 83, and the contraction of the lower connecting rod 84 and the upper connecting rod 85 is used to provide support and guidance for the support of the lower seat end shell 21 and the upper seat end shell 41, so as to prevent the pressure ring 46 and the pressure-bearing rubber ring 24 from being offset by force;
[0049] S7: Finally, the structure between the pressure ring 46 and the pressure-bearing rubber ring 24 contracts, allowing the internal pressure oil to enter the cavity plate 61 through the bottom outer groove 64, and enter the branch end 62 through the cavity plate 61, and emerge through the small holes on the side through the screw through hole 63 on the branch end 62. Due to the liquid tension, the small holes on the side of the screw through hole 63 will only emerge from the small holes on the side of the screw through hole 63 through the branch end 62 when the pressure ring 46 and the pressure-bearing rubber ring 24 contract. The bolt components are lubricated by the emerging pressure oil to prevent oxidation and rust of the bolts in the screw through hole 63.

6. A shock absorbing method for a highway bridge shock absorbing support according to claim 5, characterized in that: The following steps are involved: S1: The downward movement of the upper seat end shell (41) pushes the pressure plate (71) to move downward to squeeze the top surface of the rubber arch block (22), and through the pressure plate (71), the pressure plate (71) fits the inside of the lower seat end shell (21) through the supporting corrugated plate (72), and contacts the top surface of the side sticker (25) after pressing down through the downward pressing square column (73), thereby playing a role of pressure positioning on the side sticker (25) to prevent the rubber arch block (22) from deviating toward the center of the lower seat end shell (21); S2: When the top seat plate (5) applies downward pressure, the top of the rubber arch block (22) is used as a force point for the lower seat end shell (21). After the top of the rubber arch block (22) is pressurized, the pressure is transmitted from the middle to the end through the arc-shaped rubber arch block (22), and the side blocks (25) of the arc-shaped rubber arch block (22) contact the lower seat end shell (21), thereby utilizing the pressure of the top of the rubber arch block (22) to decompose the pressure, and the elastic material buffers the force received; S3: In addition, the top of the rubber arch block (22) will be pressed downward to press the contact position of the connected cross arch block (23), and part of the force on the rubber arch block (22) will be directed downward, so that the cross arch block (23) and the rubber arch block (22) can be compressed and contracted together to improve the buffering effect, thereby preventing the rubber arch block (22) from deforming too quickly after being compressed; S4: Subsequently, when the top seat plate (5) is under pressure, it pushes the connected upper seat end shell (41) downward toward the lower seat end shell (21), and allows the pressure ring (46) in the upper seat end shell (41) to contact the arc surface of the cross arch block (23) downward, so that the bottom of the pressure ring (46) contracts inward. At the same time, the damping arc block (47) connected to the pressure ring (46) contacts the lower pressure-bearing rubber ring (24) through the bottom arc, so that the damping arc block (47) squeezes the top of the pressure-bearing rubber ring (24) to expand outward, thereby improving the buffering effect through the friction between the pressure ring (46) and the cross arch block (23) and the rubber deformation material; S5: Afterwards, the pressure ring (46) and the pressure-bearing rubber ring (24) slide against each other, reducing the internal space between the pressure ring (46) and the pressure-bearing rubber ring (24), allowing the pressure oil between the pressure ring (46) and the pressure-bearing rubber ring (24) to enter the middle of the rubber gasket (43). At this time, the pressure ring (46) squeezes the rubber gasket (43) together with the pressure rod (42) above and the pressure rod (42) below the top seat plate (5), so that the buffer sheet in the rubber gasket (43) is pressed in the middle to cause the two sides to tilt up. The tilting causes the pressure oil to enter the lubricating groove (44) through the gap between the buffer sheets. After the rubber gasket (43) is restored, the pressure oil in the lubricating groove (44) is retained in the lubricating groove (44). The rubber gasket (43), the pressure ring (46) and the pressure-bearing rubber ring (24) are protected by the lubricating groove (44), thereby preventing the rubber material structure from being oxidized and improving the service life of the rubber structure. S6: When the top seat plate (5) and the base plate (1) are brought close to each other, the ball joint block (82) connected to the bottom hinge seat (81) squeezes the lower connecting rod (84) close to the upper connecting rod (85) through the spherical joint (83), and the contraction of the lower connecting rod (84) and the upper connecting rod (85) is used to provide support and guidance for the support of the lower seat end shell (21) and the upper seat end shell (41), thereby preventing the pressure ring (46) and the pressure-bearing rubber ring (24) from being offset by force; S7: Finally, the structure between the pressure ring (46) and the pressure-bearing rubber ring (24) contracts, allowing the internal pressure oil to enter the cavity plate (61) through the bottom outer groove (64), and enter the branch end (62) through the cavity plate (61), and then emerge through the small hole on the side of the screw through hole (63) on the branch end (62). Due to the liquid tension, the small hole on the side of the screw through hole (63) will only emerge from the small hole on the side of the screw through hole (63) through the branch end (62) when the pressure ring (46) and the pressure-bearing rubber ring (24) contract. The bolt parts are lubricated by the emerging pressure oil to prevent the bolts in the screw through hole (63) from oxidation and rust.
