Example Embodiment

[0012] Such as figure 1 It is a schematic diagram of the structure of the present invention. The hydraulic support push rod includes an upper rod body 1, a lower rod body 2, a groove 3 and a fixing block 4. The upper part 1 of the rod body and the lower part 2 of the rod body are fixedly connected, and the upper part 1 and the lower part 2 of the rod body are provided with recesses. Slot 3, the upper right side of the upper part of the rod body 1 is provided with a fixing block 4, the upper part of the rod body 1 and the lower part of the rod body 2 are fixedly connected by screws 5 and fixing pins 6, the upper part of the rod body 1 is provided with a sticker 7 on the right side, and the upper part 1 of the rod body is provided There is a quick connector 8.
[0013] In use, the upper right side of the upper part of the rod body 1 is provided with a fixed block 4, and the fixed block 4 is provided with a pin hole. The tail part of the upper part of the rod body 1 and the lower part of the rod body 2 are fixedly connected by a fixed pin 6 passing through the pin hole. The head of the lower part of the rod body 2 is fixedly connected by a screw 5. The upper part of the rod body 1 and the lower part of the rod body 2 are provided with grooves 3, and the grooves 3 are combined to form an infusion pipeline. The opening of the infusion pipeline is provided with a quick connection joint 8. It is convenient and quick to connect with the outside infusion pipeline. This kind of hydraulic support push rod has simple structure, convenient use and strong practicability. The strength of the push rod is greatly improved, the service life of the push rod is prolonged, and the safety factor is enhanced. At the same time, it makes full use of the internal space of the push rod. The force-bearing component is used, and it can also take on the role of the infusion pipeline, the function has been expanded, and it is easy to apply and promote.
