Novel adjustable damping device

Abstract

The invention discloses a novel adjustable damping device which comprises a bounce seat. A mounting hole is formed in the bounce seat. A damping shaft and an adjusting shaft are arranged on the mounting hole. A spring is arranged between the damping shaft and the adjusting shaft. The mounting hole is in sealed fit with the adjusting shaft and the damping shaft to form a cavity used for being filled with damping oil. A first clamp piece is connected to one end of the damping shaft in an inserted manner, and the other end of the damping shaft extends to the outer portion of the mounting hole. The adjusting shaft is fixedly sleeved with a friction ring, the adjusting shaft and the mounting hole are in clearance fit through the friction ring, a second clamp piece is connected to one end of theadjusting shaft in an inserted manner, and an adjusting portion is arranged at the other end of the adjusting shaft. One end of the spring is connected with the first clamp piece, and the other end of the spring is connected with the second clamp piece. In the process that the adjusting shaft drives the spring to rotate through the second clamp piece, fiction force is generated between the friction ring and the mounting hole and can offset rotating force generated by acting of the spring on the adjusting shaft, the magnitude of damping force is adjusted, the structure is simple, and adjustment is convenient.

Description

technical field [0001] The invention relates to a novel adjustable damping device. Background technique [0002] The ground plug is a socket installed on the ground or similar places and used to connect with fixed wiring. It is usually used as the terminal and outlet of the ground wiring system to take out the power, signal and data in the ground wiring system. It is mainly used in large-bay indoor places such as offices, airports, hotels, shopping malls, and families, and has a wide range of uses. [0003] The traditional pop-up ground socket includes a panel, a jump frame and a pop-up mechanism. The functional parts are arranged on the jump frame. The torsion force of the spring is realized, because the torsion force of the torsion spring acts directly on the jump frame, and there is no damping device, so that the impact force of the jump frame when it bounces is large, which will generate a lot of noise and affect the service life of the product. It may also cause harm ...

Problems solved by technology

[0003] The traditional pop-up floor socket includes a panel, a jumper frame and a pop-up mechanism. The functional parts are arranged on the jumper frame. The torsion of the spring is realized. Since the torsion of the torsion spring directly acts on the jumping frame, and there is no damping device, the impact force of the jumping frame is very large when it bounces off, which will generate a lot of noise and affect the service life of the product. It may also cause harm to the human body or contact things, so a damping device is usually set to buffer the speed of the jumping frame, but this type of damping device is pre-installed in the damping seat because the damper and the spring are pre-loaded. The force is also fixed and non-adjustable when the damping device is assembled; due to the influence of measurement errors and other factors, there is often a deviation between the time when the frame jumps up and the ideal value in actual use
