Problems solved by technology

[0002] At present, the Young’s modulus measuring instruments that use steel wire as the measured object are all non-intelligent. The disadvantage of this vertical pull structure is that it needs a lot of weights, which is troublesome to store, and the weights fall to the ground due to careless operation. It is easy to hurt the operator's feet, and when adding or subtracting weights, the wire rope is easy to shake, which increases the measurement error; in addition, it is difficult to find the image of the scale during the operation, and the amount of data that needs to be manually calculated in the calculation formula is relatively large; the reading and The addition and subtraction weights are located in two places, and the operator needs to repeatedly run between the telescope and the measuring frame, causing chaos and congestion in the laboratory

Embodiment Construction

[0013] Present embodiment Young's modulus measuring instrument has following several parts to form:

[0014] 1. Intelligent Young's modulus bracket:

[0015] The intelligent Young's modulus adopts a vertical support, which consists of two vertical steel bars and three horizontal steel plates. The steel plate on the top has a groove, which is used to place the wire head fixing plate; the middle steel plate is used to place the CCD lens and the light lever device, and a hole is opened in the middle of the steel plate, so that the steel wire to be tested and the small platform of the light lever pass through the middle; The steel plate at the bottom has a slideway, and the pulley bracket can slide freely on the slideway, and the pulley bracket is locked by a locking nut.

[0016] 2. Wire head fixing plate

[0017] The steel wire head fixing plate is used for fixing the steel wire to be tested.

[0018] 3. Optical lever device

[0019] A horizontally placed laser generator is ...

Description

technical field [0001] The invention relates to a Young's modulus measuring instrument used in university physics experiments, in particular to an intelligent Young's modulus measuring instrument with vertically placed measuring supports. Background technique [0002] At present, the Young’s modulus measuring instruments that use steel wire as the measured object are all non-intelligent. The disadvantage of this vertical pull structure is that it needs a lot of weights, which is troublesome to store, and the weights fall to the ground due to careless operation. It is easy to hurt the operator's feet, and when adding or subtracting weights, the wire rope is easy to shake, which increases the measurement error; in addition, it is difficult to find the image of the scale during operation, and the amount of data that needs to be manually calculated in the calculation formula is relatively large; the reading and The addition and subtraction weights are located in two places, and ...
