Lamp cover shock test device

Abstract

The invention discloses a lamp cover shock test device which comprises sliding ways, wherein the sliding ways are in sector shapes, the four sliding ways are horizontally arranged at equal intervals,the height values of inlets of two adjacent sliding ways increase progressively, the sliding ways are fixedly connected through a support, outlets of the sliding ways are kept on the same horizontal line, a hammer head enters through an inlet of the sliding ways, and ejects form an outlet, the front part of the hammer head is hemispherical, a bas is located in front of the outlet, a lateral frameis fixed to the base, a lamp cover to be detected is embedded into the lateral frame to be located, the lateral frame is composed of an end lateral frame body and a middle lateral frame body, and theheight of the lateral frame is larger than one half of the height of the lamp cover to be detected. The device has a simple structure, the hammer head can enter from the inlet to convert gravitationalpotential energy into kinetic energy and strike the lamp cover to be detected at the outlet position, and the multiple sliding ways are arranged; furthermore, the heights of the inlets of the slidingways increase progressively, so that different striking energy can be correspondingly obtained; when the lamp cover to be detected is broken through, the impact strength of the lamp cover to be detected can be converted out according to the heights of the inlets and the weight of the hammer head.

Description

technical field [0001] The invention relates to an impact test device for a lampshade. Background technique [0002] After the production of lamps and lanterns is completed, the impact resistance strength of the lampshade needs to be tested. At present, the commonly used equipment is a pendulum impact testing machine. The hammer head hits the lampshade to be tested with the rotation of the pendulum until the lampshade to be tested is broken down. Record the weight and height measurements of the hammer head and convert them into the ultimate impact force that the lampshade can withstand. The pendulum testing machine is cumbersome to operate and has large errors, and it takes up a certain amount of laboratory space. Contents of the invention [0003] In view of the deficiencies in the above problems, the present invention provides an impact test device for a lampshade. [0004] In order to achieve the above object, the present invention provides an impact test device for a ...
