This utility model has a reasonable and simple structural design. The axial relative assembly positions of hydraulic pipe connector one and hydraulic pipe connector two are adjustable, resulting in high structural stability, good sealing, convenient assembly, and long service life.

[0004] However, the following problems were found in the implementation of the relevant technologies: although the existing joints have high structural strength and sealing performance, they often make the installation of the joints complicated and inconvenient to use. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a bidirectional hydraulic pipe connector, including two hydraulic pipe connector bodies 1 arranged side by side. The inner walls of the two hydraulic pipe connector bodies 1 facing each other are threaded, and a threaded pipe 2 is screwed between corresponding sides of the two hydraulic pipe connector bodies 1. The two hydraulic pipe connector bodies 1 can rotate relative to the threaded pipe 2 to adjust the distance between them. A rubber sleeve 3 is fitted over the outer side of the threaded pipe 2, and the rubber sleeve 3 is fitted between the outer sides of the two hydraulic pipe connector bodies 1. The rubber sleeve 3 serves as the connection point between the hydraulic pipe connector bodies 1 and the threaded pipe 2. To provide a sealing effect, the sidewall of the rubber sleeve 3 has two annular grooves (not shown in the figure) arranged side by side, and a hoop 4 is fitted inside the annular groove. The hoop 4 is used to fix the rubber sleeve 3 to the corresponding side of the hydraulic pipe connector body 1. The two ends of the hoop 4 are integrally formed with connecting pieces 5, and connecting screws 6 are screwed between the corresponding connecting pieces 5. The connecting screws 6 are used to fix the two connecting pieces 5 to ensure that the hoop 4 can be tightly fixed to the outer wall of the rubber sleeve 3 to ensure the sealing performance at this point. Fixing components are installed on the outer walls of the two opposite sides of the hydraulic pipe connector bodies 1.

[0023] Specifically, the fixing component includes a fixing ring 7 that is fixedly sleeved on the outer wall of the hydraulic pipe connector body 1, and two fixing strips 8 are integrally formed symmetrically on the outer wall of the fixing ring 7. The fixing strips 8 are used to connect the fixing ring 7 and the fixing frame 9.

[0024] Furthermore, a fixing frame 9 is welded to the side of the fixing strip 8 away from the fixing ring 7, and the side wall of the fixing frame 9 is respectively constructed with a horizontal fixing hole 10 and a vertical fixing hole 11. The horizontal fixing hole 10 is used to connect with the external structure in the horizontal direction by screws, and the vertical fixing hole 11 is used to connect with the external structure in the vertical direction by screws.

[0025] Furthermore, the connection between the hoop 4 and the connecting piece 5, and between the fixing ring 7 and the fixing strip 8, are all injection-molded integral structures. The injection-molded integral structure has higher structural strength and is less prone to breakage or damage between the structures.

[0026] It is worth noting that the side wall of the connecting screw 6 is fitted with a washer (not shown in the figure), and the washer is supported between the head of the connecting screw 6 and the corresponding side of the connecting piece 5, which can prevent the connecting screw 6 from being tightened too much and making it inconvenient to remove.

[0027] It is worth noting that flanges 12 are welded to the opposite ends of the two hydraulic pipe joint bodies 1, and the flanges 12 are flush with the corresponding sides of the hydraulic pipe joint bodies 1. The flanges 12 are used to connect the hydraulic pipe joint bodies 1 and the external pipes.

[0028] It is worth mentioning that a sticker 13 is affixed to one outer wall of the hydraulic pipe connector body 1. The surface of the sticker 13 is marked with various parameters and numbers of the current connector so that staff can quickly understand it. In addition, a protective film is affixed to the surface of the sticker 13 to prevent the corresponding side of the sticker 13 from being worn and causing the parameter information and number to become unclear.

[0029] Working principle: Connect one hydraulic pipe fitting body 1 to one external pipe via flange 12. Then, based on the position of the other external pipe, screw the other hydraulic pipe fitting body 1 relative to the threaded pipe 2 so that the flange hole of the flange 12 of the hydraulic pipe fitting body 1 is aligned with the corresponding structure of the external pipe, making connection with the external pipe easier. Then, move the rubber sleeve 3 so that it is fitted between the side walls of the two hydraulic pipe fitting bodies 1 (e.g., Figure 1 Next, tighten the connecting screw 6 on the corresponding side of the connecting piece 5 to ensure that the clamp 4 can be tightly fixed on the corresponding side of the rubber sleeve 3. In this way, the rubber sleeve 3 can be tightly fixed on the corresponding side of the hydraulic pipe joint body 1 to ensure sealing.

[0030] If conditions permit, attach the corresponding side of the fixing frame 9 to the corresponding side of the external structure. If the corresponding side of the external structure is horizontal, screw in the fixing hole 10 to fix it; otherwise, screw in the fixing hole 11 to fix it, thereby increasing the stability of the joint after installation.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
