Embodiment 1

[0022] Example 1: Please refer to Figure 1-3 , a viewing angle conversion device for psychological experiments, comprising a box body 1, the inner wall of the box body 1 is symmetrically provided with a limit chute 2, the left side of the limit chute 2 is slidably connected with a left slider 3, and the left slider 3 is connected to the The first scale 4 is fixedly connected, the right slider 5 is slidably connected to the right side of the limit chute 2, and the right slider 5 is fixedly connected to the second scale 6, and the first scale 4 and the second scale 6 run through the slot on the top of the box body 1 7 and is located outside the box body 1, the upper rack 8 is fixedly connected to the right side of the bottom of the left slider 4, the lower rack 9 is fixedly connected to the left side of the bottom of the right slider 5, and the right slider 5 is provided with a The through hole 10 matched with the upper rack 8;

[0023] Before the experiment begins, according ...

Embodiment 2

[0031] Embodiment 2: This embodiment is a further improvement of the previous embodiment: a height adjustment device is provided at the bottom of the box body 1, and the height adjustment device includes a rotation adjustment shaft 22, and the left and right sides of the rotation adjustment shaft 22 are threadedly connected with adjustment screw sleeves 23. The screw threads on the left and right sides of the rotation adjustment shaft 22 have opposite directions and equal pitches. The adjustment screw sleeve 23 is connected with a tilt adjustment rod 24 in rotation. The end of the rotation adjustment shaft 22 runs through the box body 1 and is connected with a knob 26, and the size of the outer edge of the support base plate 25 is the same as that of the box body 1;

[0032] When the device is in use, the adjusting screw sleeve 23 can be driven to move toward or back by turning the adjusting shaft 22. When moving in the opposite direction, the tilting adjusting rod 24 can drive...

Abstract

The invention discloses a psychological experiment viewing angle conversion device, and relates to psychological equipment. The psychological experiment viewing angle conversion device comprises a boxbody, wherein limiting sliding grooves are formed in the inner wall of the box body in a front-back symmetry mode, the left side of the limiting sliding groove is slidably connected with a left sliding block, the left sliding block is fixedly connected with a first ruler, the right side of the limiting sliding groove is slidably connected with a right sliding block, the right sliding block is fixedly connected with a second ruler, the first ruler and the second ruler penetrate through the top through groove of the box and are located on the outer side the box, the right side of the bottom ofthe left sliding block is fixedly connected with an upper rack, and the left side of the bottom of the right sliding block is fixedly connected with a lower rack. According to the invention, the psychological experiment viewing angle conversion device is simple in structure; during use, the synchronous rotation of three viewing angle rotating ring discs can be achieved through gear transmission, and then the specific data of viewing angle rotating rings can be obtained in a mean value taking mode, so that the situation that the large error exist in the single conversion disc is avoided; and the height of the psychological experiment viewing angle conversion device can be easily adjusted through a height adjusting device, so that the psychological experiment viewing angle conversion deviceis suitable for different crowds and convenient to use.

Description

technical field [0001] The invention relates to a psychological device, in particular to a viewing angle conversion device for a psychological experiment. Background technique [0002] In the process of psychological experiments, sometimes it is necessary to calculate the range of people's viewing angles based on the distance from the visual stimulus to the human eye, combined with the image size of the visual stimulus on the computer screen, and each experiment requires complex calculations. Calculations are very inconvenient. [0003] For this reason, the Chinese patent (authorized announcement number: CN205433716U) discloses a viewing angle conversion device for psychological experiments. The device sets the chute on the top of the installation box, and the left scale is set on the positioning guide slide Ⅰ through the movement of the horizontal slide Ⅰ. , the right scale is set on the positioning guide slide plate II through the horizontal slide plate II, the central ge...
