Description

Technical Field

[0001] This utility model relates to a shock-absorbing and sealing connector for marine equipment, belonging to the field of marine equipment technology. Background Technology

[0002] During ocean voyages, ships are continuously subjected to a combination of loads from low-frequency wave impacts, high-frequency vibrations of the main engine, and propeller pulsations. Deck electromechanical equipment and in-cabin monitoring equipment all require fixing and transfer installation via connectors. Currently, commonly used connectors in the industry are mostly rigid flanges or ordinary hinged bracket structures, which generally suffer from defects such as lack of cushioning and shock absorption, lack of waterproof sealing, and lack of anti-loosening locking.

[0003] Traditional rigid connections cannot dampen vibrations, and long-term service can easily lead to bolt loosening, wear on connection surfaces, and equipment resonance failures. Ordinary hinged brackets lack dust and water protection at the joints, allowing salt spray and condensation to easily penetrate the mating gaps, inducing metal corrosion, bushing jamming, and angle adjustment failure. Furthermore, the lack of mechanical anti-loosening locking mechanisms, relying solely on bolt friction for restraint, makes them prone to stripping, angle misalignment, and equipment installation misalignment under continuous vibration. In addition, ordinary rubber damping and sealing components are not resistant to seawater corrosion and aging, easily hardening and cracking in the high salt spray and high humidity environment of ships, resulting in low overall reliability and frequent replacements. Therefore, developing a damping and sealing connector suitable for marine operating conditions has practical engineering application value. Utility Model Content

[0026] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0027] like Figure 1-8 As shown, the marine equipment vibration damping and sealing connector includes an equipment end mounting base 11, a multi-layer corrugated vibration damping assembly 21, a joint connecting arm 41, an actuator end mounting shaft 71, an angle locking mechanism 81, and a sealing assembly. The equipment end mounting base 11 is embedded with the multi-layer corrugated vibration damping assembly 21. The multi-layer corrugated vibration damping assembly 21 is connected to one end of the joint connecting arm 41 via an upper hinge shaft 31. The other end of the joint connecting arm 41 is connected to the actuator end mounting shaft 71 via a middle hinge shaft 51. The actuator end mounting shaft 71 is connected to the actuator end mounting member 612 via a lower hinge shaft 61. The angle locking mechanism 81 is fixed on the surface of the actuator end mounting shaft 71 and is distributed correspondingly to the middle hinge shaft 51. The sealing assembly is respectively disposed on the surfaces of the upper hinge shaft 31, the middle hinge shaft 51, and the lower hinge shaft 61.

[0028] The device end mounting base 11 has a square shell structure. The device end mounting base 11 is fixedly connected to the mounting component 111. The mounting component 111 is fixed to the device end, and a gasket 112 is fixedly connected to the bottom of the mounting component 111.

[0029] The multi-layer corrugated damping component 21 is a composite rubber structure, with an inner layer of rigid supporting rubber that serves as a positioning and support. One end of the multi-layer corrugated damping component 21 is fixedly connected to the fixed shaft 211, and the other end of the multi-layer corrugated damping component 21 is pressed against the surface of the pad 112. The fixed shaft 211 is fixedly connected to the surface of the shaft 212, and the shaft 212 is movably sleeved inside the multi-layer corrugated damping component 21. The shaft 212 is also inserted through the pad 112 and the mounting component 111.

[0030] Thus, when the multi-layer corrugated damping component 21 is subjected to force, the shaft 212 moves within the mounting component 111 and the pad 112. At this time, the multi-layer corrugated damping component 21 undergoes compression deformation, which plays a buffering role.

[0031] The upper hinge shaft 31 is integrally connected to the upper end head 311 in the middle. The upper end head 311 is fixedly connected to one end of the shaft 212. The upper end head 311 and the shaft 212 can move synchronously.

[0032] The upper hinge shaft 31 is rotatably connected to one end of the joint connecting arm 41, and a chuck 312 is fixedly connected to the end of the upper hinge shaft 31 located on the outside of the joint connecting arm 41.

[0033] The outer wall of the joint connecting arm 41 is provided with a locking mechanism, which is correspondingly arranged on one side of the chuck 312. The locking mechanism includes a fixed part 412 and a movable part 413. The fixed part 412 is fixedly connected to the outer wall of the joint connecting arm 41, and the movable part 413 is rotatably connected to the fixed part 412 through a hinge. The end of the movable part 413 near the chuck 312 is provided with a locking tooth, and the chuck 312 is engaged with the chuck 312 through the locking tooth. The movable part 413 is fixedly connected to the joint connecting arm 41 through a positioning bolt 414. Thus, after the angle between the equipment end mounting base 11 and the joint connecting arm 41 is adjusted at the upper hinge shaft 31, the movable part 413 is fixed by tightening the positioning bolt 414. At this time, the locking tooth of the movable part 413 is engaged with the edge of the chuck 312, thereby restricting the rotation between the equipment end mounting base 11 and the joint connecting arm 41.

[0034] The joint connecting arm 41 is an integrally bent structure. The joint connecting arms 41 are fixedly connected to each other by connecting rods 411. The joint connecting arm 41 is fixedly connected to the central hinge shaft 51.

[0035] A middle hinge shaft 51 located on the outside of the joint connecting arm 41 is fixedly connected to a limiting shaft 511. The side wall of the limiting shaft 511 near the joint connecting arm 41 is provided with a rib 512, and a sealing assembly is provided between the rib 512 and the joint connecting arm 41.

[0036] Furthermore, a sealing assembly is provided between the other end of the joint connecting arm 41 and the chuck 312, and the side wall of the chuck 312 near the joint connecting arm 41 is also provided with a rib 512.

[0037] Furthermore, the lower hinge shaft 61 is fixedly connected to the disk at its end, the middle part of the lower hinge shaft 61 is integrally formed with the lower end 611, the lower hinge shaft 61 is rotatably connected to the execution end mounting part 612, a sealing component is provided between the execution end mounting part 612 and the disk, and the sealing component is distributed correspondingly to the ribs 512 provided on the side wall of the disk.

[0038] Thus, sealing components are installed on the upper hinge shaft 31, the middle hinge shaft 51 and the lower hinge shaft 61, which can achieve sealing at the corresponding connection points.

[0039] A gear disk 513 is fixedly connected to the middle of the hinge shaft 51. An execution end connecting part 71 is integrally formed at one end of the execution end mounting shaft 71. The execution end connecting part 711 has a U-shaped structure. The execution end connecting part 711 is rotatably connected to the surface of the hinge shaft 51, and the gear disk 513 is located inside the execution end connecting part 711.

[0040] Thus, the actuator mounting shaft 71 and the actuator connecting part 711 can rotate around the central hinge shaft 51, which is fixed on the joint connecting arm 41 to achieve stable rotation. At the same time, the sealing assembly seals the connection position between the central hinge shaft 51 and the joint connecting arm 41.

[0041] The angle locking mechanism 81 includes a fixing block 811, a screw 812, a bushing 813, and a retaining plate 814. There are two fixing blocks 811, which are fixedly connected to both ends of the actuator mounting shaft 71. The screw 812 is rotatably connected to one of the fixing blocks 811. The screw 812 located on both sides of the fixing block 811 is provided with a convex shaft to limit the axial movement of the screw 812. The bushing 813 is inserted through into the other fixing block 811. The bushing 813 has a square structure to prevent the bushing 813 from rotating. The screw 812 is threadedly connected to the bushing 813. In this way, when the screw 812 rotates, it can drive the bushing 813 to slide on the fixing block 811.

[0042] The end of the bushing 813 is fixedly connected to a retaining plate 814, which is correspondingly disposed on one side of the gear disk 513. The side of the retaining plate 814 near the gear disk 513 is provided with a toothed block with an arc structure. When the bushing 813 drives the retaining plate 814 to move, the retaining plate 814 is made to fit against the surface of the gear disk 513. At this time, the rotation of the gear disk 513 and the lower hinge shaft 61 is restricted, thereby locking the actuator mounting shaft 71 and the joint connecting arm 41 to prevent relative rotation between the two.

[0043] The sealing assembly includes a seal 91 and a clamp 912. The seal 91 and the clamp 912 are respectively embedded between the joint connecting arm 41 and the chuck 312, the joint connecting arm 41 and the limiting shaft 511, and the actuator mounting part 612 and the disc. Thus, the seal 91 is sequentially arranged at the upper hinge shaft 31, the middle hinge shaft 51 and the lower hinge shaft 61, thereby achieving sealing at the hinge position.

[0044] The sealing element 91 is an annular structure and is sequentially sleeved on the surfaces of the upper hinge shaft 31, the middle hinge shaft 51, and the lower hinge shaft 61. The chuck 312, the limiting shaft 511, and the disc are provided with a raised rib 512 on the side near the sealing element 91. The sealing element 91 is fitted and connected to the raised rib 512. The edge of the sealing element 91 is provided with a groove 911, and the groove 911 and the raised rib 512 are rigidly distributed.

[0045] The clamp 912 is a deformable arc-shaped structure. The side wall of the clamp 912 is provided with a protrusion 913. The protrusion 913 is fixedly connected to the side wall of the joint connecting arm 41 and the actuator mounting part 612 by fastening bolts 914. The inner wall of the clamp 912 is provided with a limiting rib 915. The limiting rib 915 is distributed correspondingly with the groove 911. In this way, when the clamp 912 is installed, the limiting rib 915 is fitted into the groove 911 of the sealing part 91, so that the groove 911 is opened. At this time, one side of the groove 911 is close to the protrusion rib 512, and the other side of the groove 911 is close to the side wall of the joint connecting arm 41 and the actuator mounting part 612, thereby achieving a tight fit.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
