[0029] Such as Figures 1 to 4As shown, an embodiment of the present utility model provides a hydraulic component with an installation structure, including a docking sleeve 1. Equipment connecting pipes 2 and liquid pipes 3 are respectively provided at both ends of the docking sleeve 1. A connecting component is used for the quick connection between the docking sleeve 1 and the two pipes. The connecting component is connected to the docking sleeve 1. The connecting component includes a communication cavity opened inside the docking sleeve 1. An annular partition cavity is provided in the inner wall of the docking sleeve 1. Two partition plates 102 are fixedly connected inside the partition cavity. The partition plates 102 divide the partition cavity into two expansion cavities 103 and an inner cavity 101. Two flow holes are opened inside the partition plates 102. An expansion part 104 is provided on the inner wall of the expansion cavity 103 facing the communication cavity. Connection parts 201 are provided at the connection positions of the equipment connecting pipe 2 and the liquid pipe 3 with the docking sleeve 1. The shape of the expansion part 104 is an arc-shaped protrusion, and the connection part 201 is an arc-shaped groove. The connection part 201 is in close fit with the expansion part 104. An air supply pipeline is provided at one end of the partition cavity, and the air supply pipeline is used for the pressurized expansion of the partition cavity and the expansion cavity 103. Before connection, the expansion cavity 103 inside the docking sleeve 1 is in an unpressurized state, and the expansion part 104 remains in its original state and does not protrude into the communication cavity. The preparation ends of the equipment connecting pipe 2 and the liquid pipe 3 are both provided with arc-shaped groove connection parts 201, which are prepared to cooperate with the expansion part 104 of the docking sleeve 1. The equipment connecting pipe 2 and the liquid pipe 3 are respectively aligned with both ends of the docking sleeve 1 and preliminarily inserted. At this time, the connection part 201 is in contact with the arc surface of the expansion part 104, but a tight seal has not yet been formed. Gas or liquid is injected into one end of the partition cavity through the air supply pipeline, and the gas or liquid enters the two expansion cavities 103 through the flow holes inside the partition plate 102. As the pressure in the expansion cavity 103 increases, the expansion part 104 gradually expands outwards, and its arc-shaped protrusion part is in close fit with the arc-shaped groove of the connection part 201 to form a seal. After the expansion part 104 is in close fit with the connection part 201, the installation sleeve 4 is rotated to be threadedly connected and tightened with the docking sleeve 1. The inner wall of the installation sleeve 4 abuts against one end of the inner sleeve 5, further stabilizing the positions of the equipment connecting pipe 2 and the liquid pipe 3 in the docking sleeve 1. At this time, through the close fit of the expansion part 104 and the connection part 201 between the equipment connecting pipe 2, the liquid pipe 3 and the docking sleeve 1, and the tightening effect of the installation sleeve 4, quick and reliable connection is achieved. Through the pressurized expansion of the expansion part 104 and the close fit of the connection part 201, gapless sealed connection is achieved, effectively preventing the occurrence of liquid leakage, avoiding the problem of frequent replacement of traditional gaskets due to aging, prolonging the overall service life of the hydraulic component, reducing the maintenance cost, and realizing quick connection and disassembly through simple pressurized expansion and threaded tightening operations, improving the work efficiency.

[0030] In this embodiment, as Figures 1 to 4As shown, inner sleeves 5 are provided inside both ends of the docking sleeve 1. Guide wheels 501 are provided inside both inner sleeves 5. The equipment connecting pipe 2 and the liquid pipe 3 are respectively arranged inside the two inner sleeves 5. Installation sleeves 4 are threadedly connected to both ends of the docking sleeve 1. The inner wall of the installation sleeve 4 abuts against one end of the inner sleeve 5. The equipment connecting pipe 2 and the liquid pipe 3 respectively penetrate through the installation sleeve 4 and extend to the outside. By adjusting the pressure of the gas transmission pipeline, the expansion degree of the expansion part 104 can be controlled, so as to adapt to the pipeline connection requirements of different sizes and specifications, improve the versatility and adaptability of the hydraulic components. The design of components such as the docking sleeve 1, the installation sleeve 4, and the inner sleeve 5 makes the entire hydraulic component structure compact, the installation process simple and convenient, reduces the requirement for installation space. The guide wheels 501 inside the inner sleeve 5 contribute to the smooth docking of the equipment connecting pipe 2 and the liquid pipe 3 during the insertion process, reducing the risk of poor sealing or damage caused by improper insertion. At the same time, the fastening effect of the installation sleeve 4 also enhances the stability of the connection.

[0031] The working principle provided by the present utility model is that before connection, the expansion cavity 103 inside the docking sleeve 1 is in an unpressurized state, and the expansion part 104 remains in its original state and does not protrude into the communication cavity. The preparation ends of the equipment connecting pipe 2 and the liquid pipe 3 are both provided with arc-shaped groove connecting parts 201, which are prepared to cooperate with the expansion part 104 of the docking sleeve 1. Align the equipment connecting pipe 2 and the liquid pipe 3 with both ends of the docking sleeve 1 respectively and insert them preliminarily. At this time, the connecting part 201 is in contact with the arc surface of the expansion part 104, but no tight seal has been formed yet. Inject gas or liquid into one end of the partition cavity through the gas transmission pipeline. The gas or liquid enters the two expansion cavities 103 through the flow holes inside the partition 102. As the pressure inside the expansion cavity 103 increases, the expansion part 104 gradually expands outwards, and its arc-shaped convex part closely fits with the arc-shaped groove of the connecting part 201 to form a seal. After the expansion part 104 and the connecting part 201 are closely fitted, rotate the installation sleeve 4 to threadedly connect it with the docking sleeve 1 and tighten it. The inner wall of the installation sleeve 4 abuts against one end of the inner sleeve 5, further stabilizing the positions of the equipment connecting pipe 2 and the liquid pipe 3 inside the docking sleeve 1. At this time, through the close fit of the expansion part 104 and the connecting part 201, and the fastening effect of the installation sleeve 4, a fast and reliable connection is achieved between the equipment connecting pipe 2, the liquid pipe 3 and the docking sleeve 1. Through the pressurized expansion of the expansion part 104 and the close fit with the connecting part 201, a gapless sealed connection is achieved, effectively preventing the occurrence of liquid leakage, avoiding the problem of frequent replacement of traditional gaskets due to aging, extending the overall service life of the hydraulic components, and reducing the maintenance cost.
