[0026] This utility model has the following beneficial effects:
[0027] 1. In this utility model, the pharmaceutical preparation training and teaching equipment allows teachers to adjust the height of the equipment by repeatedly stepping on the foot pedal. Stepping on the foot pedal will cause the locking block to move upward, thereby moving the teaching board to the ideal position. If the teaching board is too high during this process, the teacher can also step on the foot pedal to pull the reset rod outward. When the teaching board moves downward to the ideal position, it will be freed from the force on the reset rod. In this way, the teaching efficiency of the teacher can be improved by adjusting the height of the teaching board.
[0028] 2. In this utility model, the pharmaceutical preparation training and teaching equipment allows the teacher to change the angle of the teaching board and rotate the teaching board. When the teaching board is rotated to a position where students can easily see the content, the limiting rod on the inner wall will limit the base to prevent the teaching board from rotating back and forth, which would be detrimental to the teaching process. In this way, by adjusting the angle of the teaching board, the teaching content can be fully displayed, thereby improving the students' listening efficiency. Attached Figure Description

[0039] 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.
[0040] Reference Figures 1-3 This utility model provides an embodiment of a pharmaceutical preparation training and teaching device, including a support plate 1. A lifting mechanism 2 is provided on the top of the outer wall of the support plate 1. The lifting mechanism 2 is mainly used to adjust the height of a teaching board 5. The lifting mechanism 2 includes a fixed rod 21, and a foot pedal 22 is hinged to the bottom end of the outer wall of the fixed rod 21. The foot pedal 22 facilitates the teacher's height adjustment of the teaching board 5. The bottom of the outer wall of the fixed rod 21 is fixedly connected to the top of the outer wall of the support plate 1. A connecting rod 23 is hinged to the inner wall of the foot pedal 22, and a hinge plate 24 is hinged to the top of the inner wall of the connecting rod 23. The connecting rod 23 forms a connection, allowing the teacher to adjust the height of the teaching board 5 by using their foot pedal. When stepping on the footplate 22, the footplate 22 and the hinge plate 24 can be in the same motion state at the same time. The outer wall of the hinge plate 24 is hinged to the top of the outer wall of the fixed rod 21. The inner wall on the left side of the hinge plate 24 is elastically connected to the locking block 26 through the spiral spring 25. One end of the spiral spring 25 is fixedly connected to the rotation center axis on the left side of the hinge plate 24, and the other end of the spiral spring 25 is fixedly connected to the rotation center axis on the outside of the locking block 26. When the height of the teaching board 5 is raised, the locking block 26 and the sliding rod 27 engage multiple times. In order to ensure that the locking block 26 engages with the sliding rod 27 multiple times, the spiral spring 25 will reset the position of the locking block 26 after movement.
[0041] Reference Figures 3-4A connecting block 28 is fixedly connected to the top of the left outer wall of the fixed rod 21. A reset rod 210 is elastically connected to the inner wall of the connecting block 28 through a reset spring 29. The outer wall of the reset rod 210 slides and passes through the inner wall of the connecting block 28. One end of the reset spring 29 is fixedly connected to the inner wall of the left side of the connecting block 28, and the other end of the reset spring 29 is fixedly connected to the middle of the side of the reset rod 210. When the sliding rod 27 moves up and down, the bottom of the outer wall of the reset rod 210 repeatedly engages with the groove of the side wall of the sliding rod 27. In order to achieve a stable effect, the elasticity of the reset spring 29 acts on the reset rod 210, so that the reset rod 210 automatically engages with the groove of the sliding rod 27.
[0042] Reference Figures 2-7 The outer wall of the reset rod 210 is slidably connected to the top of the left outer wall of the fixed rod 21. The left outer wall of the sliding rod 27 has multiple sets of holes and slots. The outer wall of the reset rod 210 is engaged with the inner wall of the holes and slots of the sliding rod 27. When the teacher adjusts the height of the teaching board 5, it helps to stabilize the position of the teaching board 5 and prevent the teaching board 5 from sliding down. The empty slot on the left side of the sliding rod 27 is parallel to the positioning slot on the right side. The inner wall of the fixed rod 21 is slidably connected to the sliding rod 27. The outer wall of the right side of the sliding rod 27 has a positioning slot. The outer wall of the locking block 26 is in contact with the inner wall of the positioning slot. The contact between the two allows the sliding rod 27 to move when the inner wall of the fixed rod 21 is raised by the lifting of the hinge plate 24 in conjunction with the locking block 26. This allows for more precise adjustment of the height of the teaching board 5, which is beneficial for the teacher's teaching. The locking block 26 is rotatably connected to the left inner wall of the hinge plate 24. The top of the outer wall of the sliding rod 27 is fixedly connected to the base 3. The top of the outer wall of the base 3 is rotatably connected to the teaching board 5.
[0043] Reference Figure 1 and Figure 8 A limiting component 4 is provided on the inner wall of the bottom end of the teaching board 5. When the teacher rotates the teaching board 5 to a position where students can easily see the content on the teaching board 5, the teaching board 5 is limited to prevent it from being unstable in a position where students can clearly see the content on the teaching board 5. The limiting component 4 includes a limiting rod 42 elastically connected to the inner wall of the bottom end of the teaching board 5 through a limiting spring 41. One end of the limiting spring 41 is fixedly connected to the inner wall of the bottom end of the teaching board 5, and the other end of the limiting spring 41 is fixedly connected to the side of the limiting rod 42. In the middle, the top of the outer wall of the base 3 has multiple sets of slots. When the teaching board 5 rotates, the slots of the base 3 act on the limiting rod 42 multiple times. The bottom of the limiting rod 42 is triangular, which facilitates the limiting rod 42 to spontaneously disengage from the base 3 when the teaching board 5 rotates. Due to the elastic action of the limiting spring 41 on the limiting rod 42, the limiting rod 42 engages with the base 3. The outer wall of the limiting rod 42 contacts the inner wall of the slot of the base 3. The limiting rod 42 passes through and slides on the inner wall of the bottom end of the teaching board 5.
[0044] Working principle: During the teaching process, when the teacher raises the teaching board 5, the teacher steps on the foot pedal 22, which moves downward. This causes the connecting rod 23 to move downward, and the hinge plate 24 causes the locking block 26 to rotate upward. The upward rotation of the locking block 26 causes the sliding rod 27, which is engaged with the locking block 26, to move upward along the inner wall of the fixed rod 21 until the locking block 26 engages with the next positioning groove of the sliding rod 27 again. At this point, the spiral spring 25 resets the position of the locking block 26 after its upward rotation. During the movement of the sliding rod 27, the inner wall of the slot in the sliding rod 27 presses against the inclined surface of the reset rod 210, causing the reset rod 210 to disengage from the slot of the sliding rod 27 and slide on the inner wall of the connecting block 28. Because the bottom of the outer wall of the reset rod 210 has a three-dimensional shape... The angled cut surface of the teaching board 210 allows the reset rod 210 to engage with the positioning groove of the sliding rod 27 again due to the reaction force of the reset spring 29. This allows the teaching board 5 to adapt to the teacher's height, facilitating teaching and improving teaching efficiency. When the teacher adjusts the height of the teaching board 5 too high, they can pull the reset rod 210 outward. At this time, the reset spring 29 is compressed, and the reset rod 210 disengages from the positioning groove of the sliding rod 27. The teaching board 5, base 3, and limiting component 4 descend due to gravity. When the position of the teaching board 5 after descending is adapted to the teacher's height, it disengages from the force on the reset rod 210. Due to the reaction force of the reset spring 29, the reset rod 210 engages with the positioning groove of the sliding rod 27 again to stabilize the state of the teaching board 5, which is more conducive to teaching.
[0045] During the teaching process, when the teacher needs to adjust the angle of the teaching board 5, the teacher can rotate the teaching board 5. During the rotation of the teaching board 5, the inner wall of the slot of the base 3 will press against the inclined surface at the bottom of the limiting rod 42. During the pressing process, the limiting spring 41 connected to the limiting rod 42 is in a compressed state, and the limiting rod 42 disengages from the base 3. When the teacher rotates the teaching board 5 again, the limiting rod 42 will re-engage with the slot of the base 3 due to the reaction force of the limiting spring 41. Due to the rotational connection between the teaching board 5 and the base 3, the teaching board 5 can be guided and will not disengage from the base 3 during movement. When the teaching board 5 is rotated to a position where students can clearly see the content on the teaching board 5, the limiting rod 42 will be subjected to the elastic force of the limiting spring 41 again and re-engage with the slot of the base 3, thereby stabilizing the state of the teaching board 5 and preventing the teaching board 5 from rotating again. In this way, the teaching content can be fully displayed by adjusting the angle of the teaching board 5, thereby improving the students' listening efficiency.
[0046] 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.
