Being easily damaged, maintenance cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of new digital timer, to solve proposition in above-mentioned background technology
Problem.
For achieving the above object, this utility model following technical scheme of offer: a kind of new digital timer, including timing
Device body and handle, described handle is arranged on timer body both sides by rotating connector；Described timer body trailing flank
It is provided with on and off switch；Electric magnet terminals and button it is provided with below described on and off switch；Described timer body trailing flank
Bottom is provided with the first photogate terminals and the second photogate terminals, is respectively provided with above described second photogate terminals
There are function select button and peek key；Described timer body trailing flank middle position is provided with seven segment numerical tube display；Institute
State seven segment numerical tube display side and be provided with display lamp；Described timer body both sides and top are provided with honeycomb-type heat radiation
Hole.
Preferably, described on and off switch is provided with self-locking, and is electrically connected with display lamp.
Preferably, described first photogate terminals and the second photogate terminals are provided with connecing of three different colours
Mouthful.
Preferably, described display lamp is provided with 9, and a word is arranged in seven segment numerical tube display side.
Compared with prior art, the beneficial effects of the utility model are: this utility model coordinates supporting photogate to carry out
Kinematic digital exploration is tested, and function has timing of being in the light, interval timing, collision experiment, measuring acceleration, measuring gravity to accelerate
The functions such as degree, survey cycle, counting, electric magnet, complete function, data are the most reliable.This new digital timer uses four seven
Segment numeral pipe video data, and have data memory function.Compared with conventional digital timer, structure design more ingenious, use more
Safety, dangerous without electric leakage electric shock, perfect heat-dissipating, its rotatable handle facilitates taking and placing.
