As an indispensable key part of the hydraulic system, the hydraulic pipeline bears the important task of transmitting hydraulic oil and ensuring effective transmission of hydraulic power. However, the existing hydraulic pipeline assembly still has some defects in use.

At the same time, the hydraulic pipeline sealing structure uses two sealing rings to seal the connection. This sealing method combined with threaded connection may cause gaps and leakage at the sealing part, which reduces the sealing effect.

[0004] Therefore, we propose a hydraulic pipeline assembly with sealing docking mechanism to solve the problems mentioned above. INVENTION CONTENTS

[0012] With the above structure, the threaded rod can be flexibly rotated through the positioning bearings, thereby driving the movable plate and the clamping half-ring to closely fit with the corresponding clamping groove, thereby realizing the quick and firm butt joint of the connecting head and the mounting base. Compared with the traditional thread embedding connection method, the phenomenon of locking and being unable to disassemble after long-term use can be effectively avoided, and the convenience of disassembly and maintenance is improved.

The synchronous operation of connection and sealing is realized by the design of the driven sealing, without additional sealing operation steps, so that the installation process is simplified. Meanwhile, the inlaid design of the expansion sealing ring can avoid affecting the insertion of the connecting head and the mounting seat, further improving the operation convenience of the connection. Moreover, the cooperation of the two groups of expansion sealing rings and the sealing grooves forms a double sealing structure, significantly improving the sealing effect and effectively preventing hydraulic oil leakage.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Please refer to Figures 1-6 The utility model provides a kind of technical solutions: a kind of hydraulic piping assembly with sealing docking mechanism, including hydraulic pipe body 1 and mounting seat 3, the both ends of hydraulic pipe body 1 are fixedly installed with connecting head 2, the outer ring of connecting head 2 is sleeved with mounting seat 3, two-way clamping mechanism, it is symmetrically arranged in the outer ring of connecting head 2 and mounting seat 3 for realizing the quick docking of both, two-way clamping mechanism includes the positioning bearing 4 symmetrically embedded in the outer ring of connecting head 2, the inner ring of positioning bearing 4 is fixedly connected with threaded rod 5, threaded rod 5 is rotatably connected with connecting head 2 by positioning bearing 4, threaded rod 5 is fixedly installed with rotary knob 6 at the end away from positioning bearing 4, the outer ring of threaded rod 5 is sleeved with movable plate 7, movable plate 7 is screw connected with threaded rod 5, the inside of movable plate 7 is provided with limiting groove 8, limiting groove 8 is penetrated with limiting plate 9 in the inside, the end of limiting plate 9 close to connecting head 2 is fixedly connected with it, movable plate 7 forms limiting sliding structure with limiting plate 9 by limiting groove 8, the bottom of movable plate 7 is fixedly installed with connecting seat 10, connecting seat 10 is fixedly connected with clamping half ring 11 at the end away from limiting plate 9, the outer ring of mounting seat 3 is provided with clamping groove 12, clamping half ring 11 is movably hinged with clamping groove 12;

[0028] The design of the above structure, when connecting the mounting seat 3 and the connecting head 2, align the mounting seat 3 with the connecting head 2, and sleeve the connecting head 2, so that the clamping groove 12 corresponds to the clamping half ring 11, then rotate the rotating knob 6, because the threaded rod 5 is rotatably connected with the connecting head 2 through the positioning bearing 4, the positioning bearing 4 reduces the friction when rotating, so that the rotating knob 6 can drive the threaded rod 5 to rotate around its axis, with the rotation of the threaded rod 5, the movable plate 7 connected with the threaded rod 5 will move along the axial direction of the threaded rod 5 based on the screw transmission principle, because the movable plate 7 is connected with the limiting plate 9 through the limiting groove 8 to form a limiting sliding structure, so the limiting groove 8 slides along the limiting plate 9, limiting the rotation of the movable plate 7, ensuring that the movable plate 7 can only move linearly along the threaded rod 5, then the movable plate 7 moves in the process, the connecting seat 10 drives the clamping half ring 11 to move synchronously, when the movable plate 7 moves towards the mounting seat 3, the two symmetrically arranged clamping half rings 11 gradually approach the clamping groove 12, until they are embedded in the clamping groove 12 and engaged, at this time, the symmetric clamping half rings 11 form a clamping force on both sides of the mounting seat 3, firmly fixing the mounting seat 3 on the connecting head 2, completing the quick butt joint of the hydraulic pipe body 1 and the mounting seat 3, realizing the stable and reliable connection of the two, and the reverse rotation of the rotating knob 6 can drive the movable plate 7 to move, and cooperate with the connecting seat 10 to drive the clamping half ring 11 and the clamping groove 12 to separate, when the two symmetric clamping half rings 11 completely separate from the clamping groove 12, the clamping force on the mounting seat 3 disappears, at this time, the mechanical connection between the mounting seat 3 and the connecting head 2 is released, the mounting seat 3 can be easily removed from the outer circle of the connecting head 2, completing the disassembly operation of the hydraulic pipe assembly.

[0029] The driven sealing mechanism is symmetrically arranged at the connection between the connecting head 2 and the mounting seat 3 and is linked with the bidirectional clamping mechanism, the driven sealing mechanism comprises piston cylinders 13 symmetrically arranged on both sides of the connecting head 2, the piston cylinders 13 are internally slidably connected with piston plates 14, the piston plates 14 are connected with the inner walls of the piston cylinders 13 through springs 15 on one side, the other side of the piston plates 14 is fixedly connected with connecting rods 16, the connecting rods 16 are fixedly connected with driven plates 17 at the end away from the piston plates 14, the driven plates 17 are slidably connected with the threaded rod 5, the driven plates 17 are fixedly connected with the movable plate 7, the driven sealing mechanism further comprises a connecting pipe 18 fixedly connected to one end of the piston cylinder 13, the connecting pipe 18 is symmetrically arranged about the center line of the connecting head 2 and is embedded in the connecting head 2, the bottom end of the connecting head 2 is fixedly connected with expansion sealing rings 19, the expansion sealing rings 19 are arranged in two groups, the expansion sealing rings 19 are fixedly connected with the grooves arranged at the bottom of the connecting head 2, the inner circle of the mounting seat 3 is provided with sealing grooves 20, the sealing grooves 20 are arranged in two groups, the expansion sealing rings 19 are tightly fitted with the sealing grooves 20 after expansion;

[0030] The above structure is designed so that after the connector 2 is inserted into the mounting base 3, when the driven plate 17 moves, the connecting rod 16 pulls the piston plate 14 to slide inside the piston cylinder 13 and compress the spring 15. As the piston plate 14 moves, the compressed gas inside the piston cylinder 13 flows through the connecting pipe 18 to the expansion sealing ring 19 at the bottom of the connector 2. After the gas enters the expansion sealing ring 19, it expands and deforms. The two sets of expansion sealing rings 19 expand outward and tightly fill the two sets of sealing grooves 20 in the inner ring of the mounting base 3, forming multiple sealing lines to achieve efficient sealing at the connection between the connector 2 and the mounting base 3, effectively preventing hydraulic oil leakage.

[0031] When disassembly is required, rotate knob 6 in the opposite direction. Movable plate 7 drives driven plate 17 to move in the opposite direction. Spring 15 gradually recovers its deformation and pushes piston plate 14 back. Gas in expansion seal ring 19 is drawn back to piston cylinder 13 through connecting pipe 18. After expansion seal ring 19 loses its air pressure, it returns to its original shape, making it easy to separate mounting base 3 from connector 2.
