Screws are threadedly connected inside the fixing plates, and the pressing plates are respectively threadedly connected to the end side walls of the screws.

[0005] Preferably, telescopic rods are fixedly installed on the side walls of the fixing plates, and the output ends of the telescopic rods are respectively fixedly connected to the side walls of the pressing plates, so as to prevent the screws from driving the pressing plates to rotate when rotating.

[0006] Preferably, a clamping groove is provided inside the side wall of the extrusion plate, so that the side wall of the hydraulic pipe is connected to the inside of the clamping groove, which can prevent the hydraulic pipe from rotating.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0017] Embodiment 1

[0018] Please refer to Figures 1-3 , the embodiment of the present utility model provides a leak-proof hydraulic pipe joint, including a hydraulic pipe connector 1 and a pressing plate 6. A threaded connecting pipe 2 is fixedly installed inside the hydraulic pipe connector 1. The threaded connecting pipe 2 is threadedly connected to the hydraulic pipe. A support ring 3 is fixedly sleeved on the outer side wall of the hydraulic pipe connector 1. Fixing plates 4 are fixedly installed at equal intervals on the upper end of the support ring 3. A screw rod 5 is threadedly connected inside the fixing plate 4. The pressing plates 6 are respectively threadedly connected to the side walls of the ends of the screw rods 5. When using the hydraulic pipe connector 1, threadedly connect the threaded connecting pipe 2 with the hydraulic pipe. After the connection is tightened, rotate the screw rods 5 respectively, so that the screw rods 5 move inside the fixing plates 4, driving the pressing plates 6 to squeeze the side wall of the hydraulic pipe, making the connection between the pressing plates 6 and the side wall of the hydraulic pipe firm, thereby being able to strengthen the stability of the position after the connection of the hydraulic pipe connector 1.

[0019] Embodiment 2

[0020] In this embodiment, as Figures 1-3 shown, telescopic rods 7 are fixedly installed on the side walls of the fixing plates 4. The output ends of the telescopic rods 7 are fixedly connected to the side walls of the pressing plates 6 respectively. A clamping groove 8 is arranged inside the side wall of the pressing plate 6. When connecting the pressing plate 6 with the hydraulic pipe, clamp the hydraulic pipe 6 inside the clamping groove 8, which can strengthen the stability of the hydraulic pipe. Anti-slip pads 9 are fixedly installed at equal intervals on the inner side wall of the clamping groove 8. The anti-slip pads 9 are made of rubber. After the side wall of the hydraulic pipe enters the inside of the clamping groove 8, make the side wall of the hydraulic pipe closely fit with the anti-slip pads 9, thereby being able to strengthen the firmness of the connection between the pressing plate 6 and the hydraulic pipe.

[0021] It should be noted that in this embodiment, when using the leak-proof hydraulic pipe joint, as Figures 1-3As shown, when using the hydraulic pipe connector 1, threadedly connect the threaded connecting pipe 2 to the hydraulic pipe. After the connection is tightened, separately rotate the screw rod 5 so that the screw rod 5 moves inside the fixed plate 4, causing the hydraulic pipe 6 to be clamped inside the card slot 8. By squeezing the side wall of the hydraulic pipe with the squeezing plate 6, the connection between the squeezing plate 6 and the side wall of the hydraulic pipe is tightened, thereby being able to enhance the stability of the position after the connection of the hydraulic pipe connector 1. At the same time, after the side wall of the hydraulic pipe enters the inside of the card slot 8, the side wall of the hydraulic pipe fits tightly with the anti-slip pad 9, thereby being able to enhance the tightness of the connection between the squeezing plate 6 and the hydraulic pipe.
