The invention discloses an audio and video equipment impact test device, which comprises a bottom board. The fixed end of a telescopic pole is fixedly connected on the upper surface of the bottom board; the upper end of a telescopic end of the telescopic pole is fixedly connected with the right end of a cross bar; the left end of the cross bar is fixedly connected to the outer side surface of a sleeve pipe; a vertical sliding hole of the sleeve pipe is in slide connection with the outer side surface of a sliding rod; the upper surface of the sleeve pipe is rotatably connected with one end of arotation plate through a rotation pin; the outer side surface of the sliding rod is provided with a clamping groove in the vertical direction; the clamping groove is located corresponding to the sliding rod; and a screw hole in the lower end of the sliding rod is fixedly connected with the upper end of a connecting screw rod. The audio and video equipment impact test device is high in impact precision and good in test repeatability; and by adjusting the height of the sliding rod and the number of balancing weights, impact energy is allowed to be adjustable, and an impact cone only hits the upper surface of a video device to be detected once, thereby improving reliability of the audio and video equipment impact test device, and ensuring repeatability.
Description
technical field [0001] The invention relates to the technical field of impact test devices, in particular to an impact test device for audio and video equipment. Background technique [0002] The impact test is used to assess the mechanical strength of the equipment or the impact resistance during transportation, and is widely used in the safety performance testing of audio and video equipment, home appliances, information products, batteries, automobiles and other products. According to the standard requirements, the impact test device makes the equipment under test be impacted with a certain energy. The key to the impact test is to ensure the accuracy and repeatability of the impact. The existing audio and video impact test equipment has low impact accuracy and poor test repeatability. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an impact test device for audio and video eq...
