The belt mounting groove 33 is connected to the detection mechanism 41 by the belt. When the rotating chamber 11 rotates, it also drives the detection end of the detection mechanism 41 to rotate. The detection end of the detection mechanism 41 outputs a signal when it rotates, which is detected and identified by the PLC installed in the electrical installation drawer 42. The PLC sends a control command to the horizontal adjustment mechanism to control the displacement end of the horizontal adjustment mechanism to move horizontally, thereby driving the aperture structure to move horizontally.

[0027] In use, a belt is fitted between the driven pulley 25 and the belt mounting groove 33, thereby driving the rotating shaft 29 to rotate. The rotating shaft 29 rotates within the deep groove ball bearing 32. The rotation angle signal of the driven pulley 25 can be easily detected through the coupling 28 and the encoder 27. The damper 30 can provide a certain damping force when the rotating shaft 29 rotates. When no external force is applied to the handwheel 13, the driven pulley 25 and the rotating chamber 11 can stop rotating.

[0028] For example, such as Figure 1 , Figure 2 and Figure 5 As shown, this utility model also includes, the horizontal adjustment mechanism comprising: Support plate 18 is installed at the bottom of the fixed compartment 4; The ball screw slide 19 is fixed to the top of the support plate 18 near the center, and the top of the displacement block it has is fixed to the crossbeam plate 15 by bolts.

[0029] When in use, the ball screw slide 19 drives the displacement block to move horizontally, thereby driving the crossbeam plate 15 to move horizontally. The slider 21 is sleeved on the top of the guide rail 20 and connected to the bottom of the crossbeam plate 15, which can provide support for both sides of the bottom of the crossbeam plate 15, which helps to improve the stability of the crossbeam plate 15 when moving horizontally. When the crossbeam plate 15 moves horizontally, it can drive the adapter plate 10 to move horizontally.

[0030] For example, such as Figure 1 As shown, the present invention also includes connecting rods A8 welded to both sides of the movable vertical box 5, connecting rods B9 fixed to the outside of the connecting rods A8, and the bottom ends of the connecting rods A8 and B9 being fastened to both sides of the adapter plate 10 by screws.

[0031] When the adapter plate 10 is rotating, the connecting rods A8 and B9 are tightly connected to both ends of the adapter plate 10, which can drive the connecting rods A8 and B9 and the displaceable vertical box 5 to move horizontally, thereby driving the aperture structure to move horizontally.

[0032] For example, such as Figure 1 , Figure 10 and Figure 11As shown, the present invention also includes a slot provided at the top of the fixed chamber 4 corresponding to the horizontal adjustment mechanism, a cover plate 44 installed at the upper end of the slot, side baffles 38 provided on both sides of the fixed chamber 4, and a gap provided between the side baffles 38 and the cover plate 44 for the adapter plate 10 to pass through.

[0033] When in use, the horizontal displacement mechanism can be easily inspected from the top of the fixed chamber 4 by opening the cover plate 44. The adapter plate 10 can pass through by setting a gap between the side baffle 38 and the cover plate 44.

[0034] For example, such as Figure 1 , Figure 2 and Figure 3 As shown, this utility model also includes, the aperture structure comprising: The settling trough 43 is located at the end of the movable vertical box 5 away from the organ pipe 7; The aperture-shaped sheet metal 22 is installed on the outside of the recess 43 by screws, and a limit groove is provided at one end of its inner wall; Lens 23 is positioned between the limiting groove and the sink 43.

[0035] During use, the limiting groove and the sink 43 cooperate to easily lock and fix the lens 23.

[0036] For example, such as Figure 1 , Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, this utility model also includes a large cover plate 34 installed at one end of the fixed vertical housing 6 near the organ pipe 7 via a rectangular groove. A maintenance groove A35 is provided at one end of the large cover plate 34 near the center. A U-shaped pressure plate A36 is installed on the outer wall of the maintenance groove A35 by screws. A maintenance groove B37 is provided at one end of the movable vertical housing 5 near the organ pipe 7. A U-shaped pressure plate B39 is fixed to the outer side of one end of the maintenance groove B37 by screws. One end of the organ pipe 7 is pressed and fixed between the outer wall of the maintenance groove A35 and the inner wall of the U-shaped pressure plate A36, and the other end of the organ pipe 7 is pressed and fixed between the outer wall of the maintenance groove B37 and the inner wall of the U-shaped pressure plate B39.

[0037] In use, the outer wall of the inspection slot A35 cooperates with the inner wall of the U-shaped pressure plate A36 to facilitate the clamping and fixing of one end of the organ pipe 7, and the outer wall of the inspection slot B37 cooperates with the inner wall of the U-shaped pressure plate B39 to facilitate the clamping and fixing of the other end of the organ pipe 7.

[0038] For example, such as Figure 1 As shown, the present invention also includes, the drawing device comprising: Support frame B16 has a certain gap with support frame A1; LED lightbox mechanism 17 is installed on the top of the support frame B16, and a picture for display is provided on the side of it near the support frame A1; Button 3 is installed on the panel at one end of the fixed vertical box 6, and is electrically connected to the LED light column provided in the LED light box mechanism 17 through an electrical connection wire.

[0039] In use, the LED lightbox mechanism 17 facilitates the display of pictures. The button 3 is electrically connected to the LED light column of the LED lightbox mechanism 17. When pressed, the LED light column inside the LED lightbox mechanism 17 is turned on to provide backlighting, making it convenient for people to view the pictures displayed on one side of the LED lightbox mechanism 17.

[0040] For example, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 11 As shown, the present invention also includes a decorative toothed ring 14 welded to the visible outer surface of the rotating chamber 11.

[0041] When in use, the decorative toothed ring 14 makes it easy to decorate the visible surface of the outer side of the rotating chamber 11, thus enhancing its aesthetics.

[0042] In use, the electrical structure of this device is connected to an external power source for power supply. The support frame A1 and support frame B16 are arranged in a suitable position so that the center of the aperture-shaped sheet metal 22 is aligned with the LED light box mechanism 17. A certain distance is provided between the support frame A1 and support frame B16. A PLC is installed in the electrical installation drawer 42 to receive the detection signal from the detection mechanism 41 and control the operation of the ball screw slide 19. It can also receive the control signal from the button 3 to control the operation of the LED light column in the LED light box mechanism 17. During the experience, the person stands near the end of the fixed vertical box 6 close to the handwheel 13. Since the rotating end of the plate bearing 40 is connected to the rotating chamber 11, when the person holds the handwheel 13 and applies rotational force, the rotating chamber 11 will rotate. The belt mounting groove 33 is connected to the driven pulley 25 contained in the detection mechanism 41 by the belt. When the rotating chamber 11 rotates, it also drives the detection end of the detection mechanism 41, namely the driven pulley 25, the coupling 28 and the encoder 27, to rotate. The damper 30 can provide a certain damping force when the rotating shaft 29 rotates. When the person does not apply external force to the handwheel 13, the driven pulley 25 and the rotating chamber 11 can stop rotating. When the encoder 27 rotates, it outputs a signal, which is detected and identified by the PLC installed in the electrical installation drawer 42. The PLC then issues a control command to the horizontal adjustment mechanism. When the ball screw slide 19 is working, it drives the displacement block to move horizontally, thereby driving the crossbeam plate 15 to move horizontally. The slider 21 is sleeved on the top of the guide rail 20 and connected to the bottom of the crossbeam plate 15, which can provide support for both sides of the bottom of the crossbeam plate 15, which helps to improve the stability of the crossbeam plate 15 when moving horizontally. When the crossbeam plate 15 moves horizontally, it can drive the adapter plate 10 to move horizontally. Since the movable vertical box 5 is connected to the adapter plate 10 through the connecting rod B9, the horizontal position of the movable vertical box 5 and the aperture structure can be adjusted. The lens 23 installed in the aperture structure can simulate the zoom process of the aperture by moving horizontally with the aperture structure. By fitting the outer wall of the inspection slot A35 with the inner wall of the U-shaped pressure plate A36, one end of the bellows tube 7 can be easily pressed and fixed. By fitting the outer wall of the inspection slot B37 with the inner wall of the U-shaped pressure plate B39, the other end of the bellows tube 7 can be easily pressed and fixed. The bellows tube 7 installed between the fixed vertical box 6 and the movable vertical box 5 can extend and retract with the horizontal movement of the movable vertical box 5, always blocking the peripheral light in the space between the lens 23 and the protective glass 12, preventing peripheral light from interfering with viewing. After applying external force to the handwheel 13, the operator presses button 3 to power the LED light column inside the LED light box mechanism 17, causing the LED light box mechanism 17 to display the picture at one end of the displacement. The picture is backlit. When the operator rotates the handwheel 13 to move the aperture structure to the appropriate position, the image displayed by the picture device can be viewed through the protective glass 12 to obtain the best viewing effect. This display device has a structure that allows the operator to easily adjust the focus through mechanical interaction, resulting in a better experience for the operator when participating in the interaction.
