Description

Technical Field

[0001] This utility model relates to the field of docking plug technology, and in particular to a double-spring buffer type shockproof docking plug device. Background Technology

[0002] In modern industrial automation, aerospace, communication base stations, and rail transportation, reliable connections between electrical equipment are fundamental to the stable operation of systems. As equipment operating environments become increasingly complex, dynamic loads such as vibration and shock occur frequently, placing higher demands on the seismic resistance of electrical connection components.

[0003] However, in the existing technology, existing docking plug devices usually adopt rigid connection or simple single-point, single-direction buffer design such as a single rubber gasket or a single spring, which are mainly for axial (insertion and removal direction) buffering. They are very weak in resisting lateral (perpendicular to the insertion and removal direction) vibration and impact. Seismic waves are complex multi-directional movements, and the lateral component often has greater destructive force. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a double-spring buffer type anti-vibration docking plug device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a double-spring buffer type anti-vibration docking plug device, comprising:

[0006] Installation compartment;

[0007] A multi-directional shock absorption component, wherein a shock absorption enhancement component is connected to one side of the multi-directional shock absorption component, the multi-directional shock absorption component includes a sliding frame fixedly connected to the mounting chamber, a first rubber frame fixedly connected to the sliding frame, a piston rod slidably connected to the first rubber frame, a sliding block fixedly connected to the side of the piston rod away from the first rubber frame, an interface fixedly connected to the sliding block through a fixed frame, a square frame slidably connected to the top of the first rubber frame, and a first damping element fixedly connected to the square frame.

[0008] In a preferred embodiment, the shock-absorbing and reinforcing component includes a second rubber rod slidably connected to a first rubber frame, a connecting rod fixedly connected to the second rubber rod via a crossbar, a rubber chamber slidably connected to the connecting rod, an air outlet pipe fixedly connected to the rubber chamber, and a rubber pad fixedly connected to one end of the air outlet pipe away from the rubber chamber.

[0009] The above technical solution is adopted: When the crossbar pushes the first piston plate through the connecting rod during use, the first piston plate can slide the rod in the rubber chamber so that the air outlet pipe inflates the rubber pad and places it under the interface. When the vibration is small, the rubber pad will not bulge, avoiding long-term pressure on the interface and causing interface deformation.

[0010] In a preferred embodiment, a first piston plate is fixedly connected to the connecting rod, and the side of the first piston plate away from the crossbar is slidably connected to the rubber chamber. A second piston plate is fixedly connected to the second rubber rod, and the second piston plate is slidably connected to the first rubber frame. A transverse piston plate is fixedly connected to the piston rod, and the transverse piston plate is slidably connected to the first rubber frame.

[0011] The above technical solution is used in the following way: when a horizontal piston plate is set up, when air is blown into the sliding frame, the piston rod can push the sliding block to move on the installation chamber.

[0012] In a preferred embodiment, a first rubber rod is slidably connected to the side of the first rubber frame away from the second rubber rod, and a third damper is fixedly connected to the first rubber rod.

[0013] The above technical solution is adopted: when in use, multiple dampers are set to improve the shock resistance of the component. When the vibration is small, the damping effect is achieved through multiple dampers.

[0014] In a preferred embodiment, the ends of the first damper and the third damper that are away from the sliding frame are slidably connected within the mounting chamber.

[0015] The above technical solution is adopted: by setting the first damper and the third damper in sliding connection in the installation chamber, it is easy for them to play a shock absorption role.

[0016] In a preferred embodiment, a series plate is fixedly connected to the bottom of the interface, and a second damper is fixedly connected to the bottom of the series plate. The side of the second damper away from the first piston plate is slidably connected to the installation chamber.

[0017] The above technical solution involves setting a second damper inside the installation chamber. When vibration occurs, the second damper undergoes elastic deformation within the installation chamber to achieve a damping function.

[0018] In a preferred embodiment, a mounting block is fixedly connected to the sliding block, a universal joint is fixedly connected to the side of the mounting block away from the sliding block, and a transmission rod is fixedly connected to the side of the universal joint away from the sliding block. The transmission rod is slidably connected to the square frame.

[0019] The above technical solution is adopted: when in use, a universal joint is provided, which makes the connection between the sliding block and the transmission rod more flexible.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] When the interface vibrates, the vibration force is transmitted to the sliding block through the connecting frame, causing the piston rod to slide within the first rubber frame. This causes the transverse piston plate and the second piston plate to move together, and then the second rubber rod and the crossbar drive the first piston plate to slide within the rubber chamber. Ultimately, the rubber pad bulges at the bottom of the interface, achieving the absorption and dissipation of vibration energy. It can simultaneously cope with vibrations in multiple directions, including axial and transverse directions, and can better adapt to complex multi-directional motion environments such as seismic waves. It effectively solves the problem of weak resistance to transverse vibration and impact in existing technologies. Attached Figure Description

[0038] 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.

[0039] like Figure 1-5 As shown, this utility model provides a technical solution: a double-spring buffer type anti-vibration docking plug device, comprising:

[0040] Installation compartment 1;

[0041] The multi-directional shock absorption component 2 has a shock absorption enhancement component 5 connected to one side. The multi-directional shock absorption component 2 includes a sliding frame 21 fixedly connected to the installation chamber 1. A first rubber frame 22 is fixedly connected to the sliding frame 21. A piston rod 23 is slidably connected to the first rubber frame 22. A sliding block 24 is fixedly connected to the side of the piston rod 23 away from the first rubber frame 22. An interface 3 is fixedly connected to the sliding block 24 through a connecting frame 210. A square frame 27 is slidably connected to the top of the first rubber frame 22. A first damping 28 is fixedly connected to the square frame 27.

[0042] The shock absorption and enhancement component 5 includes a second rubber rod 51 slidably connected to the first rubber frame 22. A connecting rod 53 is fixedly connected to the second rubber rod 51 via a crossbar 52. A rubber chamber 54 is slidably connected to the connecting rod 53. An air outlet pipe 55 is fixedly connected to the rubber chamber 54. A rubber pad 56 is fixedly connected to one end of the air outlet pipe 55 away from the rubber chamber 54. In use, when the crossbar 52 pushes the first piston plate 6 through the connecting rod 53, the first piston plate 6 can slide along a preset track inside the rubber chamber 54. By changing the gas volume inside the chamber, the compressed gas is stably delivered to the rubber pad 56 through the air outlet pipe 55, realizing the conversion and release of vibration energy into gas potential energy. When the vibration is small, the rubber pad 56 remains in a natural state, avoiding plastic deformation of the interface 3 due to continuous force, effectively ensuring the mechanical performance and electrical connection stability of the interface 3.

[0043] In this utility model, when the interface 3 vibrates during use, the vibration force is first transmitted through the interface 3 to the sliding block 24 via the connecting frame 210. The sliding block 24 drives the piston rod 23 to slide within the first rubber frame 22, causing the transverse piston plate 9 to slide within the first rubber frame 22. The first rubber frame 22, made of rubber, undergoes elastic deformation, causing the second piston plate 8 to be squeezed out. This causes the second piston plate 8 to drive the second rubber rod 51 to be squeezed out, which in turn causes the second rubber rod 51 to move the crossbar 52. This causes the crossbar 52 to drive the first piston plate 6 to slide within the rubber chamber 54. The rubber chamber 54, made of rubber, supplies air to the rubber pad 56 through the air outlet pipe 55, causing the rubber pad 56 to bulge at the bottom of the interface 3, further enhancing the shock absorption effect on the interface 3.

[0044] When the first rubber frame 22 is displaced, the transmission rod 26 will cause the square frame 27 to tilt upwards, causing the first damper 28 to undergo elastic deformation to offset part of the vibration force. The first rubber rod 29 will be squeezed out by the air pressure inside the first rubber frame 22, causing the third damper 10 to undergo elastic deformation to further offset the vibration force.

[0045] like Figures 3 to 5 As shown, a first piston plate 6 is fixedly connected to the connecting rod 53. The side of the first piston plate 6 away from the crossbar 52 is slidably connected to the rubber chamber 54. A second piston plate 8 is fixedly connected to the second rubber rod 51. The second piston plate 8 is slidably connected to the first rubber frame 22. A transverse piston plate 9 is fixedly connected to the piston rod 23. The transverse piston plate 9 is slidably connected to the first rubber frame 22. When the air pressure in the sliding frame 21 changes, the gas pressure acts evenly on the transverse piston plate 9, and the force is transmitted to the sliding block 24 through the piston rod 23. This structure ensures the efficiency and stability of force transmission, enabling the sliding block 24 to achieve controllable displacement in the installation chamber 1, enhancing the device's response to vibrations in different directions, and improving the overall buffering performance.

[0046] like Figure 4 As shown, a first rubber rod 29 is slidably connected to the side of the first rubber frame 22 away from the second rubber rod 51. A third damper 10 is fixedly connected to the first rubber rod 29. During low-intensity vibration, the damping element generates a small deformation by means of its own elastic modulus, converting vibration energy into internal energy and dissipating it slowly. During high-intensity vibration, the damping elements work together to absorb a large amount of energy through nonlinear elastic deformation, effectively suppressing vibration transmission and significantly improving the reliability of the device in complex vibration environments.

[0047] like Figures 1 to 4 As shown, the ends of the first damper 28 and the third damper 10 that are away from the sliding frame 21 are slidably connected in the mounting chamber 1, allowing the damping element to freely expand and contract in a specific direction during vibration, giving full play to its buffering performance, while avoiding stress concentration problems caused by rigid connection, ensuring long-term stable operation of the damping element and extending the service life of the device.

[0048] like Figures 3 to 5 As shown, a series plate 7 is fixedly connected to the bottom of the interface 3, and a second damper 71 is fixedly connected to the bottom of the series plate 7. The side of the second damper 71 away from the first piston plate 6 is slidably connected to the installation chamber 1. The second damper 71 is vertically arranged between the interface 3 and the installation chamber 1, forming a vertical buffer barrier. When vibration occurs, it absorbs vibration energy through compression and tension movements, effectively reducing the vertical displacement of the interface 3. It works in conjunction with other damping elements to achieve all-round vibration protection for the interface 3.

[0049] A mounting block 25 is fixedly connected to the sliding block 24. A universal joint 4 is fixedly connected to the side of the mounting block 25 away from the sliding block 24. A transmission rod 26 is fixedly connected to the side of the universal joint 4 away from the sliding block 24. The transmission rod 26 is slidably connected to the square frame 27. When in use, the universal joint 4 makes the connection between the sliding block 24 and the transmission rod 26 more flexible.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
