Embodiment Construction

[0053] Such as Figure 1 to Figure 4 As shown in each figure of the present invention, a kind of multifunctional teaching spring balance of the present invention comprises panel 1, eaves board 2, main spring 3, the device that hangs main spring 3, the device that connects experimental object, handle 7, pointer 9, scale 10, Rack locking device 11, rack one-way movement control device.

[0054] Such as figure 1 As shown, there is no scale 10 at the lower part of one of the two sides of the upper front surface of the panel 1 .

[0055] Such as figure 1 , figure 2 Shown, the device that hangs main spring 3 is made up of cylinder 4, hanger 5, adjustment circular plate 6 that tube bottom is arranged.

[0056] There is a cylinder hole 4a in the center of the bottom of the cylinder 4, and the cylinder 4 is vertically installed in the cornice hole 2a in the center of the cornice 2 through threaded engagement, and its upper end is tightly connected to the adjusting circular plate 6...

Abstract

The invention relates to a multifunctional teaching spring balance which is composed of components of a panel (1), an eave board (2), a main spring (3), a device for suspending a main spring (3), a device for connecting with an experiment object, a handle (7), a pointer (9), scales (10), a rack locking device (11) and a rack unidirectional movement control device. Because the multifunctional teaching spring balance has a measured value memory function, the measured value and the displacement of the measured experiment object can be accurately read even the multifunctional teaching spring balance is separated from the experience object after experiment. Because the rack locking device (11) can control measurement starting time, the multifunctional teaching spring balance can measure the experiment data of a required measurement process without interference of a non-required measurement process. Because the multifunctional teaching spring balance is equipped with the rack locking device (11) and a rack unidirectional movement control device, application of the multifunctional teaching spring balance is greatly expanded and can be used in many experiments which are unsuitable for widely known common spring balances.

Description

technical field [0001] The invention relates to a multifunctional teaching spring balance, in particular to a multipurpose multifunctional teaching spring balance with the function of measuring data memory. The invention also relates to a method of using the multifunctional teaching spring balance. Background technique [0002] The known public spring balance has the advantages of simple structure, clear measurement data and low price. It is widely used in schools, especially in middle and primary schools, and plays a great role in improving the teaching quality. [0003] There is shortcoming in known public spring balance, though its shortcoming has exposed for a long time, does not improve all the time. [0004] First, measure the size of the force, when the measured object is removed, the pointer returns to zero. In order for the students to observe the measured value, the teacher has to carry the spring scale and the object to be measured on it to the students. After t...
