[0050] A guide assembly 5, wherein the guide assembly 5 can be connected to the moving placement assembly 4, and the guide assembly 5 guides the moving placement assembly 4 to synchronously move upward to the bottom of the switching slot;

[0051] Two position-limiting fixing components 6 are respectively arranged on the surface of the experimental table 1 at both sides of the switching slot 11 , and the two position-limiting fixing components 6 are symmetrically arranged with respect to each other.

[0052] The driving component 3 drives the placement component 4 to move. The moving placement component 4 can move upward synchronously under the guidance of the guide component 5 until it moves to the switching slot 11, thereby realizing the switching of the placement component 4 carrying different experimental equipment, so that the experimental table 1 has multiple experimental functions and is convenient for teaching.

[0053] Embodiment 1

[0054] As one of the embodiments of this technical solution, Figure 2 As shown, the driving component 3 includes a driving motor 31, and the driving motor 31 is fixed at the bottom of the inner cavity of the mounting shell 2. The output end of the driving motor 31 is connected to the driving disk 32. Two or more connecting rods are fixed on the driving disk 32. A transmission block 33 is fixed on the end of the connecting rod. The top of the transmission block 33 is connected to the placement component 4.

[0055] The driving motor 31 drives the driving disk 32 to rotate, and the driving disk 32 drives the guide slider 34 to rotate, thereby driving the placement component 4 to move, that is, to rotate in the horizontal direction, to provide driving force for switching different placement components 4.

[0056] Furthermore, the bottom of the transmission block 33 is connected to a guide slider 34 , and the guide slider 34 is slidably connected to a guide rail 35 of an annular structure, and the guide rail 35 is fixed to the bottom side wall of the inner cavity of the installation shell 2 .

[0057] When the driving component 3 drives the placing component 4 to rotate horizontally, the guiding slider 34 also rotates synchronously on the guiding rail 35. The guiding slider 34 connected to the transmission block 33 bears most of the weight of the placing component 4, making the operation of the entire switching structure more stable.

[0058] Embodiment 2

[0059] As one of the embodiments of this technical solution, as Figure 4 shown, the placing component 4 includes guiding telescopic rods 41 distributed vertically. The guiding telescopic rods 41 are fixed on the transmission block 33. The top of the guiding telescopic rods 41 is fixed to the bottom of the placing plate 42. A detachable lifting part is arranged on the placing plate 42. Connecting parts are symmetrically arranged at both ends of the placing plate 42. The placing plate 42 is lapped with the guiding component 5 through the connecting parts.

[0060] In this embodiment, equipment required for different experiments is installed on the placing plates 42 of different placing components 4. By switching different placing components 4, the experimental table 1 has different experimental functions.

[0061] Specifically, the lifting part includes a connecting frame 43. Connecting sliders 432 are fixed to the bottoms of both ends of the connecting frame 43. The connecting sliders 432 are slidably connected inside a chute 44 located at the top edge of the placing plate 42. One end of the chute 44 is connected with an access slot 45 for the connecting slider 432 to enter and exit the chute 44. The two access slots 45 are symmetrically arranged about the center;

[0062] A handle 431, which is fixed at the center of the top of the connecting frame 43.

[0063] In this embodiment, when the moving placing component 4 rises and moves to directly below the switching slot 11 under the guidance of the guiding component, the driving component 3 stops operating. The user lifts the placing plate 42 out of the switching slot 11 through the handle 431 on the lifting part until it is placed on the limit fixing component 6, thus completing the switching and installation of the placing component 4.

[0064] When it is necessary to remove the lifting part, rotate the connecting frame 43 on the lifting part to make the connecting slider 432 on the connecting frame 43 slide inside the chute 44 until the connecting slider 432 slides to the access slot 45, and then directly pick up the lifting part.

[0065] Preferably, the connecting part includes a connecting rod 61. A pulley 461 that can be lapped with the guiding component 5 is installed at the end of the connecting rod 61.

[0066] When the placing component 4 rotates to the guiding component 5, the pulleys 461 on both sides of the placing plate 42 start to lap with the guiding component 5. During the subsequent movement of the placing plate 42, the pulleys 461 roll on the guiding component 5.

[0067] Embodiment III

[0068] As one of the embodiments of this technical solution, as Figure 4 and 8 shown, the guiding component 5 includes an outer guiding shell 51 and an inner guiding shell 53. The outer guiding shell 51 and the inner guiding shell 53 jointly enclose a guiding cavity in a fan-shaped structure. Inside the guiding cavity, there are spiral-shaped outer guide rails 52 and inner guide rails 54, that is, from one end to the other end of the outer guide rail 52 and the inner guide rail 54, it is from low to high. The outer guide rail 52 and the inner guide rail 54 are respectively fixed on the side walls of the outer guiding shell 51 and the inner guiding shell 53.

[0069] In this technical solution, when moving the placing component 4 to the guiding component 5, the pulleys 461 at both ends of the placing component 4 respectively start to contact the lowest ends of the outer guide rail 52 and the inner guide rail 54. As the placing component 4 moves, the pulleys 461 rotate on the outer guide rail 52 and the inner guide rail 54, so that the moving placing component 4 moves upward synchronously in the vertical direction. The pulleys 461 on the placing component 4 move to the highest positions of the outer guide rail 52 and the inner guide rail 54. At this time, the placing component 4 is below the switching notch 11. During this process, the guiding telescopic rod 41 extends.

[0070] Embodiment IV

[0071] As one of the embodiments of this technical solution, as Figure 6 shown, the limiting and fixing component 6 includes a placing strip plate 62. One side of the bottom of the placing strip plate 62 is rotatably connected with a connecting rod 61. The connecting rod 61 is fixed on the experimental table 1. The other side of the placing strip plate 62 extends to the top of the switching notch 11, and the placing strip plate 62 can lap with the upward moving placing plate 42.

[0072] A support rod 63, the support rod 63 is fixed on the experimental table 1 on one side of the connecting rod 61. The support rod 63 can lap with the placing strip plate 62 in a horizontally distributed state. A coil spring is arranged at the connection between the placing strip plate 62 and the connecting rod 61. The two ends of the coil spring are respectively fixed on the placing strip plate 62 and the connecting rod 61. The coil spring makes the placing strip plate 62 in a horizontal position without external force, that is, lapping with the support rod 63.

[0073] When lifting the placing component 4 through the lifting part, after the placing component 4 passes through the notch, the placing plate 42 on the placing component 4 pushes open the two placing strip plates 62 until it is at the top of the placing strip plates 62, and then places the placing plate 42 on the two placing strip plates 62 to complete the construction of the placing component 4 after switching.

[0074] Preferably, it further includes a trigger assembly 7 that can be used in cooperation with the limit fixing assembly 6. The trigger assembly 7 includes a driving rod 71. The driving rod 71 is arranged vertically. The driving rod 71 is inserted into the experimental table 1 on one side of the switching slot 11, and the driving rod 71 can slide vertically. The bottom end of the driving rod 71 is connected to two connecting ropes. The two ends of the two connecting ropes 72 extend to both sides respectively, penetrate through the experimental table 1 and are connected to the connecting column 73. The connecting column 73 is fixed on the placing strip 62.

[0075] A spring. The spring is sleeved on the driving rod 71, and the two ends of the spring are respectively fixed on the driving rod 71 and the experimental table 1.

[0076] When it is necessary to switch to another placing component 4, the original placing component 4 is lifted by the lifting part, so that the placing component 4 is separated from the limit fixing assembly 6 by a certain distance. Then, the driving rod 71 is pressed downward. During the downward movement of the driving rod 71, one end of the connecting rope is driven to move. The other end of the connecting rope drives the placing strip 62 to rotate outwards, so that the placing strip 62 does not hinder the placing component 4 from returning to the installation shell 2 through the switching slot 11. Then, the driving component 3 continues to drive the placing component 4 to move. After the placing component 4 is separated from the guiding component 5, the guiding telescopic rod 41 shortens under the action of gravity, so that the placing component 4 returns to the original height.

[0077] The switching of the placing component 4 can be facilitated through the trigger assembly 7.

[0078] Furthermore, it further includes a plurality of guiding rings 74. The connecting rope 72 passes through the guiding rings 74 in sequence, and the guiding rings 74 are distributed on the moving track of the connecting rope 72. The guiding rings 74 are fixed on the experimental table 1 through connecting rods. The position of the connecting rope 72 at the node is restricted by the guiding rings 74, so as to avoid the connecting rope 72 interfering with the function of the limit fixing assembly 6. At the same time, it also ensures that the connecting rope 72 can effectively play a transmission role.

[0079] The spring and the torsion spring in this application are not shown in the figure, and the type of the driving motor 31 is a stepping motor.
