Description

Technical Field

[0001] This invention relates to the field of psychological testing experiment technology, specifically to a psychological testing experiment device. Background Technology

[0002] Psychological testing experiments are a commonly used method in psychological research and practice. By setting up specific situations, tasks, or problems, they measure and analyze an individual's psychological characteristics, behavioral performance, and psychological processes. Sandplay therapy can be regarded as a psychological testing experiment and has its own unique characteristics. Sandplay therapy provides participants with a sand tray filled with fine sand and various sandplay objects, creating a protected space where freedom and restrictions coexist. Participants express their inner world by arranging sandplay objects, and therapists or researchers can use this to observe their behavior and reactions. For example, if a child arranges war scenes in the sand tray, it may reflect their inner conflicts or aggressive tendencies.

[0003] When using sandplay for psychological testing experiments, the sandplay figures provide individuals with a non-verbal medium for expression, allowing subconscious thoughts, emotions, and conflicts to be presented in concrete form. Therefore, different sandplay figures have different meanings. When teaching the meanings contained in the sandplay figures, due to the large number of figures, it is inconvenient to demonstrate them individually in a large space with many people. When using pictures to display them, it is not convenient to hold the pictures and display multiple sandplay figures at the same time. As a result, teaching with sandplay figures is not convenient.

[0004] Combining the above issues, we find that existing psychological testing devices on the market are difficult to avoid all of these problems when in use. Even if they can be solved, they require external tools to achieve the desired results. Therefore, we propose a psychological testing device. Summary of the Invention

After learning the model pictures on the first display plate 2104, the drive motor 2112 can be started. The drive motor 2112 drives the moving belt 2114 through the support shaft 2115. When the moving belt 2114 moves, it drives the small cylinder 2120 to move, causing the magnetic block 2119 to be inserted into the metal slot shell 2118. Driven by belt 2114, the magnetic block 2119 can push the moving plate 2116 to move, which in turn drives the display plate 2104 to move, pushing the display plate 2104 out of the outlet 16. When the display plate 2104 moves to the designated position, it will be fixed. Then, the small cylinder 2120 will retract, causing the magnetic block 2119 to disengage from the metal tank shell 2118. At this time, the new display plate 2104 can be moved to the transparent plate 13. The drive motor 2106 is started, and the drive motor 2106 drives the double gear shaft 2108 to rotate through the second shaft gear 2107. The double gear shaft 2108 then drives the first shaft gear 2109, which drives the lead screw 2111 to rotate. The lead screw 2111, in conjunction with the matching nut 2110, transmits power and can simultaneously drive the moving block 2102 to move synchronously. The remaining display plates 2104 are used as described above, which can complete the display and teaching of multiple sand figurine models.

[0044] Example 2

[0045] Please see Figure 1 , Figure 2 and Figures 8-12The present invention provides a technical solution: a psychological testing experimental device. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The sandplay model display mechanism 2 also includes a model arrangement display unit 22, which is located to the left of the model replacement display unit 21. The model arrangement display unit 22 is used to arrange multiple sandplay model pictures that have been explained, and to display multiple sandplay models as a whole, so that the sandplay model pictures can be consulted for review.

[0046] As a further definition of the sand model display mechanism 2 of the present invention, the model arrangement display unit 22 includes a support plate 2201. The right side of the support plate 2201 is fixedly connected to the left side of the display rack 11. A conveyor 2202 is fixedly installed on the support plate 2201. A guide groove 2206 is opened on the left side of the support plate 2201. Several identical small motors 2213 are arranged inside the guide groove 2206. Two synchronous pulleys 2215 are arranged on the outer side of each small motor 2213, and the output end of each small motor 2213 is fixedly connected to the inner wall of one of the synchronous pulleys 2215. The outer surfaces of the two synchronous pulleys 2215 are connected to a synchronous belt 2214 for transmission.

Each small motor 2213 has a connecting plate 2210 fixedly installed on its outer surface, and one end of each connecting plate 2210 is fixedly installed on the tray 2209. By setting up the model arrangement and display unit 22, the sandplay models that have been displayed can be arranged as a whole. When the teacher shows a new sandplay model, the learner can review it through the model arrangement and display unit 22. The teacher can also conduct interactive teaching between the new sandplay model and the sandplay models in the model arrangement and display unit 22, which is conducive to learning the psychological meaning contained in the sandplay model.

[0047] Please see Figure 10 and Figure 12 A movable guide plate 2208 is fixedly installed on the inner wall of the guide groove 2206. Each small motor 2213 moves on the outer surface of the movable guide plate 2208. By setting the movable guide plate 2208, the movable guide plate 2208 cooperates with the outer groove of the small motor 2213, which can restrict the movement of the small motor 2213, so that the small motor 2213 only moves on the movable guide plate 2208.

[0048] Please see Figure 10 and Figure 12The inner wall of the guide groove 2206 is provided with an opening 2207. Each connecting plate 2210 moves within the opening 2207. The opening 2207 provides a channel for the connecting plate 2210 to connect the small motor 2213 and the support plate 2209. During the movement of the small motor 2213 and the support plate 2209, the connecting plate 2210 can move within the path formed by the opening 2207.

[0049] Please see Figure 1 and Figure 8 A stabilizing plate 2203 is fixedly installed on the left side of the display rack 11. The front of the stabilizing plate 2203 has three slots 2204. The outer surface of each support plate 2209 is in contact with the inner wall of the slot 2204. By setting the stabilizing plate 2203 and the slots 2204, the stabilizing plate 2203 can provide certain support for the display plate 2104 and provide stable support when the display plate 2104 moves onto the support plate 2209.

[0050] Please see Figure 9 and Figure 12 A contact switch 2205 is fixedly installed on the front of the stabilizing plate 2203. The contact switch 2205 is electrically connected to the small motor 2213 through wires. By setting the contact switch 2205, the small motor 2213 is controlled to turn on and off. The separate on and off control is adopted, so that when each display plate 2104 contacts the contact switch 2205, the rotating shaft 2212 can be driven, and then the display plate 2211 can be used to fix the display plate 2104.

[0051] The specific implementation of this embodiment is as follows: After the display panel 2104 is pushed out at the outlet 16, it will be pushed onto the support plate 2209. When one end of the display panel 2104 contacts the contact switch 2205, the contact switch 2205 will energize the corresponding small motor 2213. The small motor 2213 drives the rotating shaft 2212 to rotate through the cooperation of the synchronous pulley 2215 and the synchronous belt 2214. The rotating shaft 2212 drives the fixing plate 2211 to rotate, so that the fixing plate 2211 fixes the display panel 2104, ensuring that the display panel 2104 is in a stable position. To ensure stability, the small motor 2213 starts simultaneously with the conveyor 2202. The conveyor belt of the conveyor 2202 moves the pallet 2209 accordingly, and the display board 2104 on the pallet 2209 also descends. After the display board 2104 is released from the contact switch 2205, the conveyor 2202 stops, and a new pallet 2209 is moved to the designated position to wait for the next display board 2104. The above actions are repeated so that the display boards 2104 are arranged at the stable plate 2203, which can be used by learners for review and learning.
