[0025] The elastic sleeve 3 is made of rubber material, and the elastic sleeve 3 is movably sleeved on the outside of the closing cover 10; by setting the elastic sleeve 3, when the hydraulic component is installed and fixed, the No. 1 pipe 6 is threadedly sleeved on the inside of the closing cover 10 and the closing cover 10 is sleeved on the inside of the elastic sleeve 3, and the two-way threaded column 4 is rotated at this time, so that the two-way threaded column 4 can drive the elastic sleeve 3 to tighten through the No. 1 adjustment sleeve 1 and the No. 2 adjustment sleeve 2, so that the elastic sleeve 3 can seal the gap at the connection between the No. 1 adjustment sleeve 1 and the No. 2 adjustment sleeve 2, thereby avoiding the problem of incomplete sealing of the gap at the connection when the elastic sleeve 3 is provided with an adjustment joint, which leads to leakage of hydraulic oil inside the No. 1 pipe 6, thereby improving the sealing effect after the hydraulic component is installed and fixed.
[0026] The limiting column 5 is movably sleeved on the front side of the No. 1 adjustment sleeve 1. There are two limiting columns 5, and the two limiting columns 5 are symmetrically distributed with the bidirectional threaded column 4 as the symmetry axis. By setting the limiting column 5, when the elastic sleeve 3 is tightened, the limiting column 5 can limit the No. 1 adjustment sleeve 1 and the No. 2 adjustment sleeve 2 moving toward each other, thereby avoiding the problem of poor sealing effect of the elastic sleeve 3 when the position of the No. 1 adjustment sleeve 1 and the No. 2 adjustment sleeve 2 is offset, thereby improving the accuracy of the fixed position of the elastic sleeve 3.
[0027] The threaded rod 11 is movably sleeved inside the No. 2 limiting sleeve 17, and the number of the threaded rods 11 is several, and the several threaded rods 11 are evenly distributed on the outside of the No. 1 pipe 6; by setting the threaded rod 11, when the connection between the No. 1 pipe 6 and the No. 2 pipe 7 is completed, the nut 12 is rotated so that the nut 12 can drive the No. 1 limiting sleeve 9 to move downward through the threaded rod 11, that is, drive the No. 1 pipe 6 to be tightly squeezed on the top of the No. 2 pipe 7, thereby achieving the effect of tightening the No. 1 pipe 6 and the No. 2 pipe 7, and then improving the stability of the No. 1 pipe 6 and the No. 2 pipe 7 after the connection.

[0029] The filter 14 is made of stainless steel, and is compatible with the closure cover 10. By setting the filter 14, when the hydraulic oil is being transported, the filter 14 can filter the hydraulic oil inside the No. 1 pipe 6, so that the impurities inside the hydraulic oil can be blocked to the top of the filter 14, so that when the No. 1 pipe 6 is disconnected from the No. 2 pipe 7, the hydraulic oil impurities can be removed from the opening, thereby facilitating the discharge of the hydraulic oil.
[0030] The sealing mechanism 15 includes a limiting ring 151, which is fixedly sleeved on the outside of pipe No. 1 6, and a sealing gasket 152 is fixedly connected to the bottom of the limiting ring 151. By setting the sealing mechanism 15, when pipe No. 1 6 and pipe No. 2 7 are fixedly connected, pipe No. 1 6 is rotated so that pipe No. 1 6 can be threadedly sleeved on the inside of the closing cover 10, so that pipe No. 1 6 can drive the sealing gasket 152 to be tightly squeezed on the top of the closing cover 10 through the limiting ring 151, thereby improving the sealing effect of the connection between pipe No. 1 6 and pipe No. 2 7.
[0031] The auxiliary mechanism 16 includes an anti-skid sleeve 161, which is fixedly sleeved on the outside of pipe No. 1 6, and an anti-skid groove 162 is provided on the front of the anti-skid sleeve 161; by setting the auxiliary mechanism 16, when pipe No. 1 6 is connected to pipe No. 2 7, the anti-skid sleeve 161 is rotated so that the anti-skid sleeve 161 can drive pipe No. 1 6 to rotate, so that the anti-skid groove 162 can greatly improve the friction force on the surface of pipe No. 1 6, thereby avoiding the problem that the surface of pipe No. 1 6 is relatively hard and causing difficulty in rotating pipe No. 1 6, thereby facilitating the connection between pipe No. 1 6 and pipe No. 2 7.
[0032] The working principle of the anti-leakage hydraulic element provided by the utility model is as follows:
[0033] The first step: first, when installing and fixing the hydraulic component, thread the No. 1 pipe 6 into the inside of the closing cover 10 and the closing cover 10 into the inside of the elastic sleeve 3. At this time, rotate the two-way threaded column 4 so that the two-way threaded column 4 can drive the elastic sleeve 3 to be tightened through the No. 1 adjusting sleeve 1 and the No. 2 adjusting sleeve 2, so that the elastic sleeve 3 can seal the gap at the connection between the No. 1 adjusting sleeve 1 and the No. 2 adjusting sleeve 2, thereby avoiding the problem of incomplete closure of the gap at the connection when the elastic sleeve 3 is provided with an adjustment joint, thereby causing the leakage of hydraulic oil inside the No. 1 pipe 6, thereby improving the sealing effect of the hydraulic component after installation and fixation. When the elastic sleeve 3 is tightened, the limit column 5 can limit the No. 1 adjusting sleeve 1 and the No. 2 adjusting sleeve 2 moving towards each other, thereby avoiding the problem of No. 1 adjusting sleeve The problem of poor sealing effect of the elastic sleeve 3 caused by the position deviation of the joint sleeve 1 and the No. 2 adjustment sleeve 2 is solved, thereby improving the accuracy of the fixed position of the elastic sleeve 3. When the No. 1 pipe 6 and the No. 2 pipe 7 are connected, the nut 12 is rotated so that the nut 12 can drive the No. 1 limit sleeve 9 to move downward through the threaded rod 11, that is, drive the No. 1 pipe 6 to be tightly squeezed on the top of the No. 2 pipe 7, thereby achieving the effect of tightening the No. 1 pipe 6 and the No. 2 pipe 7, thereby improving the stability of the No. 1 pipe 6 and the No. 2 pipe 7 after connection. When the No. 1 pipe 6 and the No. 2 pipe 7 are squeezed and fixed, the sealing ring 13 can fill the gap between the No. 1 pipe 6 and the No. 2 pipe 7, thereby improving the air tightness inside the No. 1 pipe 6 and the No. 2 pipe 7, that is, improving the sealing inside the hydraulic component;
[0034] Step 2: When the hydraulic oil is being transported, the filter 14 can filter the hydraulic oil in the No. 1 pipe 6, so that the impurities in the hydraulic oil can be blocked to the top of the filter 14, so that when the No. 1 pipe 6 is disconnected from the No. 2 pipe 7, the hydraulic oil impurities can be removed from the opening, thereby facilitating the drainage of the hydraulic oil. When the No. 1 pipe 6 and the No. 2 pipe 7 are fixedly connected, the No. 1 pipe 6 is rotated so that the No. 1 pipe 6 can be threadedly sleeved inside the sealing cover 10, so that the No. 1 pipe 6 can pass through the limiting ring 151 The sealing gasket 152 is driven to be tightly pressed on the top of the closing cover 10, thereby improving the sealing effect of the connection between the No. 1 pipe 6 and the No. 2 pipe 7. When the No. 1 pipe 6 and the No. 2 pipe 7 are connected, the anti-skid sleeve 161 is rotated so that the anti-skid sleeve 161 can drive the No. 1 pipe 6 to rotate, so that the anti-skid groove 162 can greatly improve the friction force on the surface of the No. 1 pipe 6, thereby avoiding the problem that the No. 1 pipe 6 surface is relatively hard and thus causing the No. 1 pipe 6 to be difficult to rotate, thereby bringing convenience to the connection between the No. 1 pipe 6 and the No. 2 pipe 7.
[0035] Compared with the related art, the anti-leakage hydraulic element provided by the utility model has the following beneficial effects:
[0036] By setting the elastic sleeve 3, when the hydraulic component is installed and fixed, the No. 1 pipe 6 is threadedly sleeved inside the closing cover 10 and the closing cover 10 is sleeved inside the elastic sleeve 3. At this time, the two-way threaded column 4 is rotated, so that the two-way threaded column 4 can drive the elastic sleeve 3 to be tightened through the No. 1 adjusting sleeve 1 and the No. 2 adjusting sleeve 2, so that the elastic sleeve 3 can seal the gap at the connection between the No. 1 adjusting sleeve 1 and the No. 2 adjusting sleeve 2, thereby avoiding the problem of incomplete sealing of the gap at the connection when the elastic sleeve 3 is provided with an adjustment joint, thereby causing the leakage of hydraulic oil inside the No. 1 pipe 6, thereby improving the sealing effect after the hydraulic component is installed and fixed.
