Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described, better to understand the present invention.
Embodiment
Arrange a tensile test box in the position of scroll head, box upper and lower side respectively stretches out six pulling force heads (for guitar), can test out by this pulling force box the pulling force that string is subject to.
The string device for measuring force be illustrated in fig. 1 shown below, comprise housing 1, in housing 1, be provided with five case partitions 10, housing 1 lumen segmentation is become six cavitys, six spring eyes 11 are provided with bottom housing 1, as shown in Figure 3, in six cavitys of housing 1, six tension springs 2 are separately installed with, the concrete pattern of tension spring 2 is shown in Fig. 4 and Fig. 5, be designed to S type, there are upper boom 12 and lower beam 13 in centre, and bottom is provided with string access aperture 9; Tension spring 2, through the spring eye 11 on housing 1, is arranged in housing 1.
Tension spring 2 is provided with knob 5 in housing 1 outside top, and the pattern of knob 5 is shown in Fig. 7, and knob 5 top is provided with screw thread 14, and bottom is provided with joystick knob 15.Knob 5 for adjusting tension spring 2 position, to adjust for string better.
