Background technique

In psychology teaching research, the influence of color and light and shade changes on emotion is a frequently studied content. In teaching research, the commonly used tools are curtains or swatches with different colors. By changing the curtains or swatches, the observer can see different colors, and then record the data of their psychological changes to obtain the color. And the relationship between light and dark changes on mood. Due to the large space occupied by the curtain or the color plate, the whole tool is bulky and inconvenient to operate; and when the different colors of the curtain or the color plate are alternately replaced, it is easy for the observer to see two colors at the same time. cause problems with each other.

SUMMARY OF THE INVENTION

The present invention is intended to provide an auxiliary tool for psychology teaching, so as to solve the problem of the relatively large volume of color experiment tools in psychology teaching in the prior art.

The technical scheme of the present invention is as follows: an auxiliary tool for psychology teaching, comprising a bracket, an eyepiece is arranged on the bracket, a color changing device is arranged on the bracket, and the color changing device comprises a sealing box, the sealing box is fixedly connected with the bracket, and the sealing box is There is a reflection mechanism at the bottom of the sealing box, an observation hole communicating with the eyepiece is arranged on the sealing box, a curtain facing the observation hole is arranged on the inner wall of the sealing box, and a rotating drum is arranged in the interior of the sealing box. A plurality of through holes are arranged on the wall of the cylinder along the circumferential direction, the through holes are provided with light-transmitting color plates, and the interior of the rotating cylinder is provided with a light source that illuminates toward the reflection mechanism.

By setting up a sealed box, the influence of external light on the color observation is avoided. By setting an observation hole for connecting with the eyepiece, it is convenient for the eyepiece to observe the curtain in the sealed box through the observation hole. Sets the curtain to receive light reflected by the reflection mechanism. Set the reflection mechanism to reflect light to the screen. Set the reel to switch different swatches against the light source, thereby producing light of different colors. A light source irradiated toward the reflection mechanism is arranged, so that the light of the light source can be irradiated on the screen after being reflected by the reflection mechanism. By arranging a transparent color plate, the light emitted by the light source passes through the color plate to form a light with a corresponding color, thereby forming a light spot of the corresponding color on the screen.

Compared with the prior art, the present invention has the advantages that the light is emitted by the light source and irradiated on the reflection mechanism through the color plate, and then the reflection mechanism reflects the light to the screen to form a light spot with a corresponding color, and the observer observes through the eyepiece and the The light spot on the screen is observed through the hole, and by rotating the drum, the light of the light source can be irradiated to the color plates of different colors, thereby forming light spots of different colors, so that the observer can see the light spots of different colors, and then realize the observation of the observer. Purpose of different colors. The formation of the light spot is formed after the light of the light source is reflected by the reflection mechanism, and the light is irradiated on the screen obliquely under the reflection of the reflection mechanism. It is smaller than the area of the light spot, and at the same time, the propagation path of the light is increased by reflection, so the color plate with a small area at the light source can form a larger area of the light spot, so that the volume of the color plate is greatly reduced. In order to achieve the purpose of reducing the overall volume.

Further, the through holes are strip-shaped holes, and the length direction of the through holes is parallel to the length direction of the drum. Disposing the through hole as a strip hole is convenient for the light passing through the through hole to form a light beam with a long strip shape, thereby facilitating the formation of a rectangular light spot on the screen, which is convenient for observation.

Further, the light source includes a long luminous body and a cover body, the light emitting body is located inside the cover body, both ends of the cover body are fixedly connected with the sealing box, and the cover body is provided with an opening facing the reflection mechanism. The light emitted by the elongated light-emitting body is distributed along the length direction of the light-emitting body, so that the light distribution through the through hole can be relatively uniform. By arranging the cover, only the light toward the opening of the cover can be irradiated on the reflection mechanism, so that the light of the light can only be irradiated to one color plate, avoiding the occurrence of light irradiating on multiple color plates. A situation in which light spots of multiple colors interfere with each other occurs.

Further, the rotating drum is rotatably connected with the sealing box through a bearing. The rotating drum and the sealing box are connected by a bearing, which can reduce the frictional force between the rotating drum and the sealing box, thereby facilitating the rotation of the rotating drum.

Further, the through holes are evenly distributed along the circumference of the drum. After the through holes are evenly distributed, the color plates can also be evenly distributed along the drum, so that each time the drum rotates through the same angle, switching between different color plates can be realized, which is convenient for operation.

Further, a turntable is fixed coaxially at the end of the rotating drum, a number of positioning grooves are arranged on the circumference of the turntable, the positioning grooves are evenly distributed along the circumference of the turntable, and the sealing box is fixedly connected with elastic pieces that swing along the radial direction of the turntable. , the elastic sheet is fixedly connected with a positioning block which is concave and convex matching with the positioning groove. By setting the turntable, the synchronous rotation of the turntable and the drum is realized. By setting the positioning groove and the positioning block, the positioning block keeps in contact with the turntable under the action of the elastic sheet. When the positioning block is snapped into the positioning groove, the position of the turntable can be fixed by the positioning block, so as to realize the position of the rotating drum. Fix it so that the angle at which the light passes through the swatch and hits the reflective mechanism remains fixed.

Further, the positioning block is cylindrical and is rotatably connected with the elastic sheet. After the positioning block and the shrapnel are rotatably connected, the positioning block can rotate relative to the turntable, thereby reducing the frictional force between the positioning block and the turntable.

Further, the positioning groove is a V-shaped groove. The V-shaped groove is inclined from the bottom of the groove to the notch. When the positioning block is located on the inclined surface, the positioning block will tend to slide to the bottom of the groove under the action of the elastic sheet, so that the turntable will rotate under the driving action of the positioning block. The turntable does not stop rotating until the positioning block is located at the bottom of the positioning groove, thereby realizing the automatic adjustment of the position of the turntable.

Further, the reflection mechanism includes a water tank for storing water, an exhaust pipe is arranged at the bottom of the water tank, a one-way valve is installed on the exhaust pipe, a piston-type air pump is fixedly connected to the bracket, and the piston-type air pump and the turntable are fixedly connected. A rack and pinion transmission mechanism is connected. By installing a water tank, the surface of the water in the water tank is used as a light reflecting surface. By setting the exhaust pipe and the piston type air pump, when the drum rotates, the piston type air pump is driven to work by the turntable and the gear rack transmission mechanism, so that the piston type air pump can inflate the exhaust pipe, so that the exhaust pipe goes into the water tank Exhaust gas, so that bubbles are generated in the water tank, and the bubbles burst when they move to the surface of the water in the water tank, thereby causing ripples on the surface of the water, and then changing the direction of the light reflected by the surface of the water, so that the screen cannot be A large and stable light spot is formed, so that the observer cannot accurately observe the corresponding color, so that when the two adjacent color plates are switched, the observer will not be able to clearly observe two different colors. , which affects the experimental results.

Further, a mesh plate is fixedly connected to the top of the exhaust pipe. By setting the mesh plate, the gas discharged from the exhaust pipe can form a large number of small bubbles under the action of the mesh plate, so as to avoid large ripples on the water surface in the water tank, which is conducive to the rapid recovery of the water surface calm.
