Description
Technical field：
The utility model is related to mechanical engineering teaching equipment field, and in particular to a kind of mechanical engineering teaching experiment dress
Put.
Background technology：
《Theory of mechanics》Mechanical key foundation class, strong, the involved Fundamentals of Mathematics of its theoretical property than it is wide,
It is more uninteresting that abstract concept is more, Students ' Learning gets up.Therefore, in the urgent need to will be abstract by way of experiment in teaching process
Theoretical visualization, help Students ' Learning basic theories, ABC and basic skills, training student problem analysis and solution are asked
The ability of topic.
At present, the experimental provision dynamic role for carrying out mechanical engineering teaching is poor, it is impossible to transfers classroom atmosphere well, can influence
To quality of instruction.
Utility model content：
Technical problem to be solved in the utility model is to overcome existing technological deficiency to teach there is provided a kind of mechanical engineering
Experimental provision, removes pendulum, and the lecture experiment of lever principle is carried out using lever, expansion link, counterweight；Set up pendulum,
Expansion link is removed, swing experiment is demonstrated using the swing of pendulum and lever, experimental provision uses simple and convenient, carries significantly
High classroom interaction and quality of instruction.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of mechanical engineering teaching experimental device, including base, the base are provided with the background board perpendicular to base,
The background board is rounded, its center is provided with rotating shaft, and rotating shaft leading section is provided with the cake block being connected with axis of rotation, cake
Block side is provided with a pair of screwed holes, one of screwed hole connection lever, another screwed hole connection expansion link, lever and flexible
Equally spaced on bar to be provided with some hanging wire grooves, pallet is hung on the hanging wire groove by hanging wire, counterweight is placed with pallet, lever is remote
Threaded one end from cake block is connected with pendulum, and rotating shaft front end is provided with angular transducer, background board and set positioned at cake block side
Angled graduation mark.
The base is provided with counterweight groove, expansion link standing groove and counterweight tank.Counterweight tank is used to increase counterweight, prevents base
It is unstable.
On the background board fluorescent material is scribbled positioned at cake block side.
The base is provided with LED, and LED is electrically connected with the battery being arranged in base.
The beneficial effects of the utility model are：Pendulum is removed, lever principle is carried out using lever, expansion link, counterweight
Lecture experiment；Set up pendulum, remove expansion link, swing experiment is demonstrated using the swing of pendulum and lever, experimental provision is used
Get up simple and convenient, greatly improve classroom interaction and quality of instruction.
