4results about How to "Reduced damping" patented technology

The utility model relates to a transverse impedance multidirectional damping steel spring device which comprises a spring outer sleeve (1), a steel spring (5) and a spring inner sleeve, the spring inner sleeve comprises a spring inner sleeve cover (2) and a spring inner sleeve base (6), and a transverse impedance elastic body (3) for transverse limiting is arranged between the spring outer sleeve (1) and the spring inner sleeve base (6). Compared with the prior art, three-direction damping amplification is adopted, besides the main vibration isolation direction, the stability and vibration in the direction perpendicular to the main vibration isolation direction of the spring can be controlled, and meanwhile the problem that the spring is subjected to transverse shearing dynamic load to cause fatigue fracture and failure of the spring is solved; therefore, the transverse stability and reliability are improved, and the service life of parts is prolonged.

This utility model provides an acceleration sensor device for monitoring temporary construction access roads, belonging to the technical field of monitoring temporary construction access roads. The acceleration sensor device includes: a monitoring base, a vibration sensing component, a signal transmission component, a protective shell, and a fixed support frame. The monitoring base is a cuboid structure with a mounting groove on its top, in which the vibration sensing component is installed. The vibration sensing component includes a sensor body, an elastic reset plate, and a counterweight. The sensor body is cylindrical and fixedly positioned at the center of the mounting groove. The counterweight is rotatably connected to the inside of the sensor body via bearings. The counterweight has an eccentrically distributed fan-shaped structure. This invention solves the technical problems of existing vibration monitoring devices for temporary construction access roads, such as complex structure, difficult installation, poor environmental adaptability, and low monitoring accuracy.

The utility model belongs to electrical equipment technical field discloses a kind of impact-resistant electrical switch, including shell, the shell outer wall one side both ends are provided with fixed block, two fixed blocks are all set with fixed hole, the middle part of the side of shell away from fixed block is set with vertical hole, and slidingly connected with slider in vertical hole, the same slide bar is fixedly connected between vertical hole top and bottom, and slide bar slidingly penetrates slider, the round hole that is compatible with slide bar is set in slider, electrical switch body is fixedly connected in the slider at the one end of shell outer side, the third magnet is fixedly connected in the slider at the top of shell inner side.In the utility model, the vibration initial speed of electrical switch body can be quickly buffered, the piston is subjected to hydraulic oil resistance in moving process, further reduces vibration amplitude, greatly reduces the vibration energy transmitted to electrical switch body, prolongs the service life of electrical switch.

The utility model relates to high pressure nitrogen shock absorber technical field, concretely relates to one -way adjustable high pressure nitrogen shock absorber of damping, including shock absorber body, the tail end of shock absorber body and the one end of damping adjustment structure keep intercommunication, including bottom cylinder, outer tube and apron in the damping adjustment structure, combine into external structure, the inboard fixed of bottom cylinder has contact block, the front end fixed of contact block has top ring, the middle part fixed of outer tube has a circle contact ring, the contact ring is inserted and is provided with the rotating rod, the bottom of rotating rod is provided with positioning assembly, the bottom of rotating rod and the sleeve ring are connected with sleeve set, so the speed of the medium in the outside in the speed of entering contact block in the through -hole in top ring will slow down, owing to the viscosity of medium, the medium volume that can reduce in shock absorber body with existing structure, so play the one -way damping adjustment function, so the plug can enlarge / reduce the exposed number of through -hole when moving up / down, and then can enlarge / reduce the damping effect of shock absorber.
