Description

Technical Field

[0001] The present invention relates to the technical field of teaching display, and particularly to a multi-angle display device for economics teaching. Background Art

[0002] Economics is a theory that studies the laws of human economic activities, namely the laws of value creation, transformation, and realization - the laws of economic development, and is divided into two major types: political economy and scientific economics. Political economy, for the interests of the class it represents, spontaneously studies the law of value or economic laws from a certain side in order to highlight the status and role of a certain class in economic activities. Scientific economics consciously studies the law of value or economic laws as a whole. Symmetrical economics is scientific economics. The core of economics is economic laws; in the view of symmetrical economics, the optimal allocation and optimal regeneration of resources are only the expansion and specific manifestations of economic laws. The object of economics should be the economic laws and economic essence behind the optimal allocation and optimal regeneration of resources, rather than staying at the level of the optimal allocation and optimal regeneration of resources. What stays at the level of the optimal allocation and optimal regeneration of resources is political economy, not scientific economics. To study the laws of economic development, it is necessary to study economic phenomena as a whole. Macroeconomics and microeconomics are two symmetrical aspects in a unified economic entity. Therefore, in the framework of the scientific symmetrical economics paradigm, there are distinctions between macroeconomics and microeconomics, but there is no difference between macroeconomics and microeconomics; while political economy always divides economics into macroeconomics and microeconomics.

[0003] [[ID=ll]]In real life, when conducting economics teaching, corresponding teaching display devices are needed. However, the existing teaching display devices have certain drawbacks. For example, the existing teaching devices do not have the function of multi-angle flipping and adjustment, and the stability is relatively poor. Therefore, a new design is carried out in this regard. Summary of the Invention

[0005] The adjustment device includes an adjustment base, and a receiving housing is fixedly connected to the top of the adjustment base. The composite mechanism is used to display economic content and is arranged on the top of the receiving platform. The connection housing is controlled to lift inside the receiving housing by a first electric push rod to control the height of the device, so as to meet different working requirements. During the lifting process, component failures are avoided. A first electric push rod is fixedly connected to the inside of the receiving housing, and the top of the first electric push rod is fixedly connected to the connection housing. The outside of the connection housing is slidably connected to the inside of the receiving housing. A limiting mechanism is fixedly connected to the middle of the bottom inside the receiving housing. The limiting mechanism is used to limit the downward trend of the connection housing inside the receiving housing, prevent the components from descending excessively, reduce the component pressure, avoid affecting the normal operation of the device, and avoid damaging the device. A steering mechanism is fixedly connected to the top of the connection housing. The receiving platform is controlled to rotate by the steering mechanism to achieve the effect of multi-angle display and improve the teaching effect. An external ring is rotatably connected to the outside of the steering mechanism, and the receiving platform is fixedly connected to the top of the external ring. During the rotation of the receiving platform, the composite mechanism is driven to display at an angle to meet the diverse needs of students.

A rotating shaft is rotatably connected to the middle of the inside of the steering housing, and the top of the rotating shaft is fixedly connected to the bottom of the receiving platform. The output end of the first motor is fixedly connected to the bottom of the rotating shaft. The rotation of the rotating shaft is controlled by the first motor, and the top of the rotating shaft drives the receiving platform to rotate to achieve the effect of multi-angle display. During the rotation of the receiving platform, the external ring rotates on the annular strip to maintain the balance of the device.

[0007] Preferably, a main gear block is fixedly connected to the outside of the rotating shaft, and a driven block is meshed and connected to the outside of the main gear block. The main gear block rotates inside the driven block along with the rotating shaft. The stability of the main gear block is maintained by the driven block to avoid shaking during rotation. The bottom of the driven block is fixedly connected to the inside of the steering housing. A receiving block is fixedly connected to the annular part at the top of the steering housing, and a rotating bead is rotatably connected to the inside of the receiving block. During the rotation of the receiving platform, it rotates in friction with the rotating bead to maintain the stability of the component during rotation, avoid deviation during rotation, and thus maintain stable rotation and prevent deviation from affecting viewing.

[0008] Preferably, the limiting mechanism includes a receiving body block, and a square reed is sleeved outside the receiving body block. When the connecting housing descends towards the inner bottom of the receiving housing, it squeezes the sliding block, causing the sliding block to squeeze the square reed on the receiving body block, thereby achieving the function of shock absorption and buffering. A sliding block is slidably connected to the top of the receiving body block. Through the reaction of the square reed, it supports the components, blocks the sliding of the components, and has a certain braking effect on the descending trend of the components. The square reed adopts a square structure, and the square spring can be more conveniently arranged and fixed to form a neat and stable spring group, improving the stability and reliability of the overall structure. One side of the outside of the sliding block is fixedly connected with a damping mechanism, and the bottom of the damping mechanism is fixedly connected with the outside of the receiving body block.

[0009] Preferably, the damping mechanism includes a cylindrical housing, a sliding rod is slidably connected to the inside of the cylindrical housing, a circular block is fixedly connected to the bottom of the sliding rod, and a spring strip is sleeved outside the sliding rod. When the sliding block squeezes and contracts the square reed, the sliding rod rises with the sliding block. When the circular block slides and rises along the inner wall of the cylindrical housing with the sliding rod, it squeezes the spring strip, and through the elastic structure, it slows down the rebound force of the square reed, thereby maintaining the stability of the device, reducing the vibration amplitude of the components, reducing component wear, thus extending the service life, reducing the impact feeling of braking, and reducing noise and vibration.

[0010] Preferably, the composite mechanism includes a composite housing, and a display screen is fixedly connected to one side of the outside of the composite housing. The display screen is used to play economic teaching content.

A receiving bracket is fixedly connected to the side of the outside of the composite housing away from the display screen, and a second electric push rod is fixedly connected between the opposite surfaces of the receiving bracket. By contracting the second electric push rod, it is convenient to place the device, reduce the probability of the components being impacted by the outside, and play a certain protective effect on the device.

By driving the friction column to slide reciprocally on the surface of the square slide rail through the sliding frame body, the cleaning area is increased, the cleaning dead angle is reduced, and the cleaning effect is improved. A friction column is rotatably connected between the opposite surfaces of the sliding frame body, and a cylindrical surface groove is formed on the outside of the friction column. By forming the cylindrical surface groove, the contact area is increased by grooving, the friction performance is enhanced, and the cleaning effect is improved. A second motor is fixedly connected to the side of the outside of the sliding frame body away from the friction column.

The spring rod supports the component, and a certain buffering effect is achieved through the spring structure, thereby reducing the amplitude of the component and improving the stability of the component. A cylindrical block is fixedly connected between the opposite surfaces of the spring rod. The sliding frame moves towards the cylindrical block side on the square slide rail. The friction column is rotated by the second motor, so that the friction column is frictionally adapted to the cylindrical block, thereby cleaning the surface of the component, reducing the accumulation of dust on the surface of the component, and preventing the influence on the subsequent friction effect.

[0013] Preferably, the processing mechanism includes a body housing, the outer side of the body housing is fixedly connected to the outer side of the composite housing, an external frame is fixedly connected to one side of the outer part of the body housing, a blower is inserted and connected to the inner side of the external frame, a connecting plate is fixedly connected to the side of the external frame far away from the blower. The body housing is used to place the electronic components of the display screen. After long-term playback, it is easy to cause the temperature inside the device to rise. The blower generates wind to move the body housing, thereby achieving the effect of ventilation and heat dissipation, reducing the temperature inside the device, and avoiding the influence of too high temperature on the device. A straight pipe is fixedly connected to the side of the connecting plate far away from the external frame, and a filter plate is fixedly connected to the side of the inner wall of the straight pipe far away from the connecting plate. The filter plate plays a role in filtering and adsorbing dust, avoiding dust from entering the device, preventing dust from accumulating on the surface of the electronic components, and affecting the heat dissipation effect of the components. A friction mechanism is fixedly connected to the inner side of the straight pipe. The air flow drives the friction mechanism to rotate through the straight pipe, so that the friction mechanism rubs the inner wall of the pipe, thereby achieving the effect of cleaning the dust on the inner wall, avoiding the influence of dust accumulation on the ventilation effect, and the outer side of the straight pipe is fixedly connected with a connecting pipe.

The contact area with the air flow is increased through the paddle, and the air flow impacts the surface of the paddle, so that the air flow drives the paddle to rotate, improving the rotation efficiency of the component. A scraper is fixedly connected to the side of the paddle far away from the connecting column, driving the scraper to rub against the inner wall of the pipe, thereby achieving the effect of cleaning the impurities on the inner wall.

The steering mechanism 15 is used to control the rotation of the receiving platform 16, so as to achieve the function of multi-angle display, improving the teaching effect. During the rotation of the receiving platform 16, the composite mechanism 2 is driven to perform angle display, meeting the diverse needs of students.

[0035] The steering mechanism 15 includes a steering housing 151. The middle of the bottom of the steering housing 151 is fixedly connected with the outside of the first motor 4.

The top of the rotating shaft 153 is fixedly connected with the bottom of the receiving platform 16. The output end of the first motor 4 is fixedly connected with the bottom of the rotating shaft 153. By controlling the rotation of the rotating shaft 153 by the first motor 4, the top of the rotating shaft 153 drives the receiving platform 16 to rotate, so as to achieve the function of multi-angle display.

The sliding frame body 206 drives the friction column 207 to reciprocate on the surface of the square slide rail 205, so as to increase the cleaning area, reduce the cleaning dead angle and improve the cleaning effect. By providing the cylindrical groove 208, the contact area is increased by grooving, the friction performance is enhanced, and the cleaning effect is improved.

The filter plate 36 plays a role in filtering and adsorbing dust, avoiding dust entering the device interior, preventing dust from accumulating on the surface of electronic components, and affecting the heat dissipation effect of components. The airflow drives the friction mechanism 38 to rotate through the straight pipe 35, so that the friction mechanism 38 frictions the inner wall of the pipe, so as to achieve the effect of cleaning the dust on the inner wall, avoiding the influence of dust accumulation on the ventilation effect, and the dust is discharged outward through the connecting pipe 37 after being cleaned, so as to reduce the dust inside the components.

The adjusting device 1 is used for lifting and rotating, so as to drive the composite mechanism 2 to turn, thus meeting the requirement of multi-angle display. Inside the adjusting device 1, the connecting shell 13 is controlled to slide inside the receiving shell 12 by the first electric push rod 14, so as to control the lifting of the device and meet different height requirements. A steering mechanism 15 is also arranged inside the adjusting device 1. Inside the steering mechanism 15, the rotating shaft 153 is driven to rotate by the first motor 4, so that the receiving table 16 rotates to facilitate changing the orientation of the composite mechanism 2, thus achieving the effect of angle display. When the first electric push rod 14 controls the lifting of the adjusting device 1, in order to avoid component failures, the limiting mechanism 17 plays a role in limiting the descending amplitude of the components, preventing the components from quickly descending due to failures and playing a certain protective role for the device. Then, a teaching video is played through the display screen 202 inside the composite mechanism 2. The support angle of the display screen 202 is controlled by the second electric push rod 204, and the friction column 207 is controlled to rotate by the second motor 211, so as to clean the dust on the surface of the components, avoid dust accumulation after long-term use, and avoid affecting the viewing effect. Therefore, the surface of the components is cleaned by friction to keep the surface of the device clean.
