Damping device, instrument mounting table capable of damping and adjusting viewing angle and instrument

Abstract

The invention discloses a damping device, an instrument mounting table capable of damping and adjusting a viewing angle and an instrument. The damping device comprises at least one movable magnetic ring; a fixed magnetic ring coaxial with the movable magnetic ring sleeves the outer periphery of the movable magnetic ring; and when the movable magnetic ring is positioned in an inner circle of the fixed magnetic ring, the two buffer mutual vibration force through magnetic attraction force and keep mutual relative positions. The damping device is delicate in design and simple in structure; througharrangement of the fixed magnetic ring and the movable magnetic ring engaged with each other, relative positions can be kept through full use of the magnetic attraction force of the two to achieve asupport effect on pieces to be assembled thereon; and when the damping device is suffered from external vibration force, as the fixed magnetic ring and the movable magnetic ring are not in hard connection, but have a certain elasticity, the impact from external vibration can be buffered through relative displacement of the two, better damping effect is achieved, the application range is wide, andthe application is flexible.

Description

technical field [0001] The invention relates to a mechanical instrument, especially a shock absorbing device, a shock absorbing and adjustable viewing angle instrument installation platform and an instrument. Background technique [0002] Construction machinery instruments are tools used to display equipment operating status and / or various operating parameters. They have various types and functions, and are widely used in various industries. [0003] In practical application, construction machinery instruments are often in various environments with frequent and large vibrations, which makes construction machinery instruments very prone to various failures due to vibration, which affects the normal use of construction machinery instruments.

Problems solved by technology

[0003] In practical applications, construction machinery instruments are often in various environments with frequent and large vibrations, which makes construction machinery instruments very prone to various failures due to vibration, which affects the normal use of construction machinery instruments

[0004] Therefore, in the actual installation process, it is often necessary to adopt a necessary shock-absorbing structure to reduce the impact of vibration on the instrument. The conventional shock-absorbing structure is realized by using a shock-absorbing structure with deformable elastic elements such as springs and shrapnel, but When these elastic elements are shock-absorbing, the vibration is buffered through their own deformation, and the shock force will cause a large impact on the elastic element itself. Once the vibration exceeds the tolerance range of the elastic element, the elastic element will lose its elasticity and fail. Play a cushioning role, and the replacement of the shock-absorbing mechanism also increases the equipment cost

[0005] On the other hand, in different applications, construction machinery instruments often require different display angles to meet the actual application needs of different installation locations and different users. However, in the current structure, the instrument is often fixed after being installed on the installation platform. , the display viewing angle cannot be adjusted, and the flexibility and applicability of the application are greatly reduced
