[0027] First embodiment
[0028] Please refer to Figure 1 and Figure 2 This embodiment provides a gap adjustment structure 100, which can fix the gasket 110 between the first connection structure 120 and the second connection structure to fill the gap between the first connection structure 120 and the second connection structure. This method does not need to drive out the pin shaft or dismantle the pipeline, saving a lot of manpower and material resources.
[0029] In this embodiment, the gap adjustment structure 100 includes: a gasket 110, an adjustment component 130, a first connecting structure 120 and a second connecting structure. A connecting hole 112 is provided on the gasket 110. The gasket 110 is arranged between the first connecting structure 120 and the second connecting structure. A mounting hole 122 is provided on the first connecting structure 120. The adjustment component 130 is installed in the mounting hole 122. The adjustment component 130 can slide relative to the mounting hole 122, and one end extends to the mounting hole 122 and then passes through the connecting hole 112 to abut against the second connecting structure, thereby fixing the gasket 110 between the first connecting structure 120 and the second connecting structure, so that the gasket 110 fills the gap between the first connecting structure 120 and the second connecting structure.
[0030] In this embodiment, after the gasket 110 is placed between the first connection structure 120 and the second connection structure, the adjustment component 130 slides relative to the mounting hole 122, so that one end of the adjustment component 130 extends to the mounting hole 122 and passes through the connection hole 112 of the gasket 110 and then abuts against the second connection structure, and the gasket 110 is fixed between the first connection structure 120 and the second connection structure. In this embodiment, when a gap appears between the first connection structure 120 and the second connection structure after working for a period of time, the gasket 110 is fixed between the first connection structure 120 and the second connection structure to fill the gap between the first connection structure 120 and the second connection structure. This method does not require the pin to be driven out or the pipeline to be dismantled, saving a lot of manpower and material resources.
[0031] In this embodiment, under the action of external force, one end of the adjustment component 130 extends out of the mounting hole 122, passes through the connection hole 112 of the gasket 110 and abuts against the second connection structure, fixing the gasket 110 between the first connection structure 120 and the second connection structure.
[0032] In this embodiment, the adjustment assembly 130 includes a fixed section 132 and a supporting section 134, the mounting hole 122 includes a first section 1222 and a second section 1224 that are connected to each other, the diameter of the first section 1222 is greater than the diameter of the second section 1224, the supporting section 134 is arranged in the first section 1222, the fixed section 132 is arranged in the second section 1224, the gasket 110 is arranged at one end of the second section 1224 away from the first section 1222, and the end of the fixed section 132 away from the supporting section 134 can extend out of the second section 1224 to fix the gasket 110 between the first connecting structure 120 and the second connecting structure.
[0033] In this embodiment, the mounting hole 122 has a third section 1226, and the third section 1226 is connected to one end of the second section 1224 away from the first section 1222. The diameter of the second section 1224 is larger than the diameter of the third section 1226. The adjustment assembly 130 also includes an elastic member 136. The fixed section 132 includes a supporting portion 1322 and a connecting portion 1324 that are connected to each other. The connecting portion 1324 is arranged close to the supporting section 134. The elastic member 136 is sleeved on the supporting portion 1322. One end of the elastic member 136 is supported by the connecting portion 1324, and the other end is supported by the bottom wall of the second section 1224. The supporting portion 1322 can extend out of the third section 1226 to fix the gasket 110 between the first connecting structure 120 and the second connecting structure.
[0034] In this embodiment, when the fixing section 132 moves in a direction away from the supporting section 134 under the action of an external force, the elastic member 136 is gradually compressed during the movement. When the gasket 110 needs to be removed from between the first connecting structure 120 and the second connecting structure, the external force is removed, and the fixing section 132 moves toward the supporting section 134 under the action of the restoring force of the elastic member 136, and disengages from the connecting hole 112, so that the gasket 110 is removed from between the first connecting structure 120 and the second connecting structure.
[0035] In this embodiment, an oil filling hole 124 is provided on the first connection structure 120 , and the oil filling hole 124 is communicated with the second section 1224 .
[0036] In this embodiment, when the gasket 110 is placed between the first connecting structure 120 and the second connecting structure, hydraulic oil is injected into the second section 1224 from the oil filling hole 124. As the amount of oil gradually increases, the oil pressure in the second section 1224 gradually increases, and the fixed section 132 gradually moves away from the supporting section 134, so that the end of the fixed section 132 away from the supporting section 134 gradually extends out of the mounting hole 122.
[0037] It should be noted that in other embodiments of the present invention, other liquids or gases may be injected into the second section 1224 .
[0038] In this embodiment, the gap adjustment structure 100 further includes an oil nozzle 140 . The oil nozzle 140 is disposed at one end of the oil filling hole 124 away from the second section 1224 .
[0039] In this embodiment, the oil nozzle 140 is installed at one end of the oil filling hole 124 away from the second section 1224. When the hydraulic oil is injected, it can seal the oil filling hole 124 to prevent the hydraulic oil from leaking out of the oil filling hole 124, causing the fixed section 132 to rebound under the action of the elastic member 136, so that the fixed section 132 is separated from the connecting hole 112, causing the gasket 110 to fall off from the first connecting structure 120 and the second connecting structure, thereby improving the fixing effect of the gasket 110.
[0040] In this embodiment, the oil filling hole 124 includes an oil filling section 1242 and a mounting section 1244 which are connected to each other. The diameter of the mounting section 1244 is larger than the diameter of the oil filling section 1242 . The oil filling section 1242 is connected to the second section 1224 , and the oil nozzle 140 is installed in the mounting section 1244 .
[0041] In this embodiment, the oil nozzle 140 is sunken and installed in the installation section 1244, which can protect the oil nozzle 140 and prevent the oil nozzle 140 from being damaged by other components protruding from the first connecting structure 120, thereby protecting the oil nozzle 140 and increasing the service life of the oil nozzle 140.
[0042] In this embodiment, the abutting section 134 is sealingly connected to the bottom wall of the first section 1222 .
[0043] In this embodiment, the supporting section 134, the fixing section 132 and the second section 1224 form a sealing ring 150. When the hydraulic oil enters from the oil filling hole 124, no leakage will occur, thereby ensuring that the oil pressure of the hydraulic oil is stable.
[0044] In this embodiment, a mounting groove 1326 is formed on the fixing section 132 . The gap adjustment structure 100 further includes a sealing ring 150 . The sealing ring 150 is disposed in the mounting groove 1326 to seal the second section 1224 and the fixing section 132 .
[0045] In this embodiment, the mounting groove 1326 is arranged on the fixed section 132, and the sealing ring 150 is installed in the mounting groove 1326 and contacts the inner wall of the second section 1224, so as to seal the second section 1224 and the fixed section 132, so that the fixed section 132, the second section 1224 and the supporting section 134 form a sealing ring 150 environment.
[0046] In this embodiment, the mounting groove 1326 is disposed around the connecting portion 1324 .
[0047] In this embodiment, the adjustment component 130 further includes a connecting section 138 , which is disposed in the second section 1224 . One end of the connecting section 138 is fixedly connected to the abutting section 134 , and the other end selectively abuts against the fixed section 132 .
[0048] In this embodiment, the abutting section 134 and the fixing section 132 are respectively located on two sides of the oil filling hole 124 .
[0049] In this embodiment, after the hydraulic oil is unloaded, the fixed section 132 moves toward the abutting section 134 under the action of the restoring force of the elastic member 136, and abuts against the connecting section 138 after moving to the connecting section 138, which can prevent the fixed section 132 from moving to the abutting section 134 due to the large restoring force of the elastic member 136. When the hydraulic oil is injected again, the fixed section 132 cannot extend out of the mounting hole 122 under the action of the oil pressure.
[0050] In summary, the gap adjustment structure 100 provided in this embodiment, in this embodiment, after the gasket 110 is placed between the first connection structure 120 and the second connection structure, the adjustment component 130 slides relative to the mounting hole 122, so that one end of the adjustment component 130 extends to the mounting hole 122 and passes through the connection hole 112 of the gasket 110 and then abuts against the second connection structure, and the gasket 110 is fixed between the first connection structure 120 and the second connection structure. In this embodiment, when a gap appears between the first connection structure 120 and the second connection structure after working for a period of time, the gasket 110 is fixed between the first connection structure 120 and the second connection structure to fill the gap between the first connection structure 120 and the second connection structure. This method does not require the pin to be driven out or the pipeline to be dismantled, saving a lot of manpower and material resources.
