[0031] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a seal for hydraulic pressure, including a rubber gasket 1, on which a plurality of mounting holes 101 are provided according to actual installation requirements. A support ring 2 is embedded and fixed in the middle of the rubber gasket 1, and a reinforcement seat 3 is fixed around the bottom outer side of the support ring 2, which cooperates with the rubber gasket 1 to form a plurality of mounting holes 101. Figure 4 As shown, in this embodiment, a mounting opening 8 for the support ring 2 to be embedded is opened in the middle of the rubber gasket 1, and a receiving groove 9 for the reinforcement seat 3 to be embedded is further opened on the outer edge of the lower end of the mounting opening 8, so that the support ring 2 and the reinforcement seat 3 can be embedded and fixed in the middle of the rubber gasket 1 as a whole to ensure the flatness of the upper and lower surfaces of the rubber gasket 1.

[0032] like Figure 2 and Figure 3 As shown, an extension rod 4 is fixed to the outer side of the reinforcement seat 3 and horizontally penetrates into the rubber gasket 1. A movable rod 5 is telescopically inserted at one end of the extension rod 4 away from the reinforcement seat 3. The movable rod 5 extends to the outer edge of the rubber gasket 1 to form a support, wherein an interlocking groove 10 is provided between the accommodating groove 9 and the edge of the rubber gasket 1, and the extension rod 4 and the movable rod 5 are both horizontally inserted into the interlocking groove 10. In a specific implementation, the interlocking groove 10 is a straight groove with a T-shaped cross section, and the end cross section of the movable rod 5 is adapted to the T-shaped structure of the interlocking groove 10. Therefore, when the movable rod 5 at the end of the extension rod 4 is horizontally inserted into the interlocking groove 10, the rubber gasket 1 can be kept open, so that the edge of the rubber gasket 1 is not easy to curl.

[0033] In addition, in this embodiment, a connecting shaft 6 is fixed to one end of the movable rod 5 facing the extension rod 4, the connecting shaft 6 is inserted into the extension rod 4 to form a telescopic structure, and a damping sleeve 7 for increasing friction is sleeved on the outer side of the connecting shaft 6. Therefore, when the movable rod 5 is telescoped at the end of the extension rod 4, the support range of the rubber gasket 1 can be adjusted, thereby facilitating the cutting of the rubber gasket 1.

[0034] The working principle provided by the utility model is that the seal for hydraulic pressure, when in use, forms a support inside the rubber gasket 1 by utilizing the support ring 2, the reinforcement seat 3, the extension rod 4, and the movable rod 5, so that the rubber gasket 1 is stretched out as a whole, which can avoid the curling of the rubber gasket 1 to a certain extent, thereby ensuring the sealing effect of the rubber gasket 1.

[0035] Moreover, the extension rod 4 and the movable rod 5 form a telescopic structure through the connecting shaft 6 and the damping sleeve 7, so that the extension rod 4 and the movable rod 5 can trim and cut the edge of the rubber gasket 1 according to the specifications of the hydraulic equipment assembly during the process of supporting the rubber gasket 1, which is easy to use.

[0036] In summary, the device can not only avoid curling to a certain extent and ensure the sealing effect, but also can be cut and trimmed, and is easy to use.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention.
