[0002] The hydraulic pipe 3 is a pipe used to transmit hydraulic pressure, which is widely used in various fields of our lives.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A hydraulic pipe joint assembly comprises two semi-cylindrical fixing assemblies 2 connected to each other by bolts 1, a hydraulic pipe 3 is connected to both ends of the joint assembly by connecting plates 4 at the ends; both ends of the inner side of the fixing assembly 2 are provided with grooves 5 for fixing the connecting plates 4, and the side walls of the grooves 5 are provided with fixing mechanisms pressed against the end faces of the connecting plates 4; the connecting ends of the two fixing assemblies 2 are provided with connecting plates 6 for connecting the two fixing assemblies 2 by bolts 1.

[0009] The beneficial effects of the present utility model are as follows: By installing the connection disk at the end of the hydraulic pipe in the card slot inside the fixed component, and pressing it outward on the connection disk through the fixing mechanism, the connection disk is pressed against the end of the inner wall of the fixed component. When hydraulic oil passes through the joint component, the hydraulic pressure generated presses on the connection disk at both ends, making the connection between the connection disk and the joint component tighter, thereby avoiding loosening of the connection between the joint component and the hydraulic pipe and resulting in oil leakage.

[0014] In order to make the objectives, technical solutions and beneficial effects of the present utility model clearer, the preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings for the convenience of those skilled in the art to understand.

[0015] As Figures 1-4 shown, the present utility model provides a hydraulic pipe joint component, which includes two semi-cylindrical fixed components 2 connected to each other by bolts 1. The hydraulic pipe 3 is connected to both ends of the joint component through the connection disk 4 at the end; card slots 5 for fixing the connection disk 4 are provided at both ends inside the fixed component 2, and a fixing mechanism for pressing against the end face of the connection disk 4 is provided on the side wall of the card slot 5; a connecting plate 6 for connecting the two fixed components 2 by bolts 1 is provided at the connection end of the two fixed components 2. When this joint component is in use, the connection disks 4 at both ends of the two hydraulic pipes 3 are stuck in the card slots 5 at both ends of the fixed component 2, then the two fixed components 2 are closed, the two fixed components 2 are fixed together by bolts 1, and then the connection disk 4 is pressed tightly by the fixing mechanism, so that the connection disk 4 is fixed tightly to the inner end face of the joint component. When hydraulic oil passes through the joint component, the hydraulic pressure generated presses on the connection disk 4 at both ends, making the connection between the connection disk 4 and the joint component tighter, thereby avoiding loosening of the connection between the joint component and the hydraulic pipe 3 and resulting in oil leakage.

[0016] The fixing mechanism is installed in the installation chamber 7 provided in the fixing component 2, and includes two pressing blocks 81, two screw rods 82, and an adjusting bolt 83. The two pressing blocks 81 are respectively slidably installed on both sides of the installation chamber 7, and the pressing ends are respectively pressed on the connection disks 4 of the two hydraulic pipes 3; the two screw rods 82 are respectively rotatably installed on two mounting plates 84 provided in the installation chamber 7, and the two screw rods 82 are respectively threadedly connected to the two pressing blocks 81; the adjusting bolt 83 is installed on the outer wall of the fixing component 2 and is drivingly connected to the ends of the two screw rods 82 through a worm and worm gear structure. The connection disks 4 of the two hydraulic pipes 3 are clamped into the card slots 5 of the fixing component 2, and then the two fixing components 2 are put together and fixed by bolts 1. The connection disks 4 are clamped inside the two fixing components 2, and then the adjusting bolt 83 is rotated. The adjusting bolt 83 drives the two screw rods 82 to rotate through the worm and worm gear structure. The two threads are respectively threadedly connected to the two pressing blocks 81, so that the pressing blocks 81 move and press on the end face of the connection disk 4, and the connection disk 4 is fixedly connected to the joint component tightly.

[0017] An internal hexagonal hole is provided at the end of the adjusting bolt 83. The provision of the internal hexagonal hole enables the adjusting bolt 83 to be rotated more conveniently and labor-savingly with a hexagonal wrench.

[0018] Rubber sealing sheets 21 are provided at the connection ends of the two fixing components 2. The provision of the rubber sealing sheets 21 can prevent oil leakage.

[0019] Working process:

[0020] When the joint component is in use, the connection disks 4 at the ends of the two hydraulic pipes 3 are clamped into the card slots 5 at both ends of the fixing component 2, and then the two fixing components 2 are closed and fixed together by bolts 1. Then the adjusting bolt 83 is rotated. The adjusting bolt 83 drives the two screw rods 82 to rotate through the worm and worm gear structure. The two threads are respectively threadedly connected to the two pressing blocks 81, so that the pressing blocks 81 move and press on the end face of the connection disk 4, and the connection disk 4 is fixedly connected to the joint component tightly. When hydraulic oil is passed through the joint component, the oil pressure generated presses on the connection disk 4 at both ends, making the connection between the connection disk 4 and the joint component tighter, thus avoiding loosening of the connection between the joint component and the hydraulic pipe 3 and resulting in oil leakage.
