Description

Technical Field

[0001] This utility model relates to the field of psychology technology, and in particular to a perspective switching device for psychological experiments. Background Technology

[0002] Psychology is a science that studies human psychological phenomena, mental functions, and behavior. It is both a theoretical and an applied discipline, encompassing two major areas: basic psychology and applied psychology. Psychological research involves many areas such as perception, cognition, emotion, personality, behavior, interpersonal relationships, and social relationships, and is also related to many aspects of daily life—family, education, health, and society.

[0003] The applicant discovered through a search that a Chinese patent discloses "A Perspective Switching Device for Psychological Experiments," with publication (announcement) number "CN206403787U." This patent mainly uses length and angle pointers to directly display data, providing more intuitive information and improving experimental efficiency, making the experiment faster and more accurate. However, when adjusting the height of the display panel, the operator needs to run back and forth between the seat and the display panel, which is cumbersome and slows down the experimental progress. Therefore, we propose a perspective switching device for psychological experiments. Utility Model Content

[0004] The purpose of this invention is to provide a perspective switching device for psychological experiments, in order to solve the problem mentioned in the background art that when operators adjust the height of the display panel, they need to run back and forth from the seat to adjust the height between the display panel and the seat, which is a cumbersome experimental procedure that leads to slow experimental progress.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a perspective conversion device for psychological experiments, comprising a load-bearing plate and a lifting assembly, wherein the lifting assembly includes a throttle, a driven bevel gear and a placement box, the throttle is connected to a connecting rod via a turntable, the end of the connecting rod away from the turntable is fixedly connected to a driving bevel gear, the driven bevel gear is connected to a support plate via a threaded rod, and the bottom of the support plate is slidably connected to the placement box.

[0006] As a preferred embodiment, a load-bearing block is fixedly connected to the top surface of the load-bearing plate, a stool is fixedly installed on the top of the load-bearing block, and casters are fixedly connected to the four corners of the bottom of the load-bearing plate.

[0007] As a preferred embodiment, one side of the turntable is fixedly connected to one end of the throttle, one end of the connecting rod is fixedly connected to the other side of the turntable, and the driving bevel gear and the driven bevel gear are meshed together.

[0008] As a preferred embodiment, the bottom of the driven bevel gear is rotatably connected to the inner bottom wall of the placement box, one end of the threaded rod is fixedly connected to the top surface of the driven bevel gear, the inside of the support plate is provided with a threaded groove that matches the threaded rod, and the other end of the threaded rod is threadedly connected to the inside of the support plate.

[0009] As a preferred embodiment, the top of the lifting assembly is provided with an adjustment assembly, which includes a motor housing. The motor housing is fixedly installed on the top surface of the support plate, and a servo motor is fixedly installed inside the motor housing. The output end of the servo motor is fixedly connected to a transmission rod.

[0010] As a preferred embodiment, a circular plate is fixedly connected to the end of the transmission rod away from the servo motor, and an indicator is fixedly connected to the circumferential surface of the circular plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the lifting component, when the handle is turned, the handle will drive the turntable to rotate, and the turntable will drive the active bevel gear fixed at one end of the connecting rod to rotate. Since the active bevel gear and the driven bevel gear are meshed, the threaded rod on the surface of the driven bevel gear rotates inside the support plate, causing the support plate to move up and down. The height of the device can also be flexibly adjusted according to different experimental needs and the height of the participants, providing a more comfortable and suitable observation angle for the experiment. This eliminates the need for the operator to run back and forth to adjust the operation, saves a lot of experimental time, and improves experimental efficiency.

[0013] 2. After adjusting the height using the adjustable components, start the motor. The motor drives a transmission rod fixed at one end to rotate, which in turn drives a circular plate fixed at the other end to move. The circular plate then drives an indicator fixed on the surface to move in a circular motion. This allows for quick adjustment of the indicator's position and angle according to different experimental scenarios and needs, increasing the device's convenience. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see the appendix Figure 1 Appendix Figure 2 and appendix Figure 5 A perspective switching device for psychological experiments includes a load-bearing plate 1 and a lifting assembly 2. The lifting assembly 2 includes a handle 201, a driven bevel gear 205, and a placement box 208. The handle 201 is connected to a connecting rod 203 via a turntable 202. A driving bevel gear 204 is fixedly connected to the end of the connecting rod 203 away from the turntable 202. The driven bevel gear 205 is connected to a support plate 207 via a threaded rod 206. The bottom of the support plate 207 is slidably connected to the placement box 208. A load-bearing block 5 is fixedly connected to the top surface of the load-bearing plate 1, and a stool 4 is fixedly installed on the top of the load-bearing block 5. Universal wheels 6 are fixedly connected to the four corners of the bottom of the heavy plate 1. One side of the turntable 202 is fixedly connected to one end of the handle 201. One end of the connecting rod 203 is fixedly connected to the other side of the turntable 202. The driving bevel gear 204 and the driven bevel gear 205 are meshed and connected. The bottom of the driven bevel gear 205 is rotatably connected to the inner bottom wall of the placement box 208. One end of the threaded rod 206 is fixedly connected to the top surface of the driven bevel gear 205. The support plate 207 has a threaded groove inside that matches the threaded rod 206. The other end of the threaded rod 206 is threadedly connected to the inside of the support plate 207.

[0023] The top two sides of the placement box 208 are provided with sliding grooves, and the bottom of the support plate 207 is slidably connected to the inside of the sliding groove, so as to facilitate the up and down movement of the support plate 207. The inside of the load-bearing block 5 is provided with a rotating groove adapted to the connecting rod 203.

[0024] Specifically, through the lifting component 2, when the handle 201 is turned, the handle 201 drives the turntable 202 to rotate, which in turn causes the active bevel gear 204, which is fixed at one end of the connecting rod 203 connected to the turntable 202, to rotate. Since the active bevel gear 204 is meshed with the driven bevel gear 205, the threaded rod 206 on the surface of the driven bevel gear 205 rotates inside the support plate 207, thereby driving the support plate 207 to move up and down. In this way, the height of the device can be flexibly adjusted according to different experimental needs and the height of the participants, providing a more comfortable and suitable observation angle for the experiment. This design eliminates the step of the operator running back and forth to make adjustments, greatly saving experimental time and significantly improving experimental efficiency.

[0025] Example 2:

[0026] Please see the appendix Figure 1 Appendix Figure 3 and appendix Figure 4 Furthermore, based on Embodiment 1, the top of the lifting assembly 2 is provided with an adjustment assembly 3, which includes a motor housing 305. The motor housing 305 is fixedly installed on the top surface of the support plate 207. A servo motor 301 is fixedly installed inside the motor housing 305. A transmission rod 302 is fixedly connected to the output end of the servo motor 301. A circular piece 303 is fixedly connected to the end of the transmission rod 302 away from the servo motor 301. An indicator 304 is fixedly connected to the circumferential surface of the circular piece 303.

[0027] The circular disc 303 serves to connect the transmission rod 302 and the indicator 304, enabling the power of the servo motor 301 to be effectively transmitted to the indicator 304, thus providing a power basis for the circular motion of the indicator 304.

[0028] Specifically, after adjusting the height of the device using the adjustable component 3, the servo motor 301 is started. The servo motor 301 then drives the transmission rod 302, which is fixedly connected to one end, to rotate. The transmission rod 302 further drives the circular plate 303, which is fixedly connected to one end, to move. This causes the indicator 304, which is fixed on the surface of the circular plate 303, to make circular motion. In this way, the position and angle of the indicator 304 can be quickly adjusted according to different experimental scenarios and needs, which greatly increases the convenience of the device.

[0029] Working principle of this utility model: This utility model is a perspective conversion device for psychological experiments. First, rotating the handle 201 causes the turntable 202 to rotate, which in turn causes the connecting rod 203 to rotate. The driving bevel gear 204 connected to the other end of the connecting rod 203 also begins to rotate. Since the driving bevel gear 204 is meshed with the driven bevel gear 205, the driven bevel gear 205 rotates under the drive of the driving bevel gear 204. The top surface of the driven bevel gear 205 is fixedly connected to the threaded rod 206. When the driven bevel gear 205 rotates, the threaded rod 206 also rotates. The support plate 207 has an opening that matches the threaded rod 206. The threaded groove is fitted, and the bottom sides of the support plate 207 are slidably connected to the inside of the placement box 208, so that the rotational motion of the threaded rod 206 is converted into the vertical linear motion of the support plate 207. In this way, the height of the support plate 207 can be adjusted, thereby realizing the height adjustment of the entire device. Then, after the motor in the motor box 305 is started, its output end drives the transmission rod 302 to rotate. The circular piece 303 fixedly connected to one end of the transmission rod 302 also rotates accordingly. The indicator 304 on the surface of the circular piece 303 also makes a circular motion. Through the forward and reverse control of the motor, the position and angle of the indicator 304 can be precisely adjusted, thereby realizing the fine adjustment of the viewing angle.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
