Description

Technical Field

[0001] This invention relates to the field of display cabinet technology, and more specifically, to a multi-view display cabinet and its display method. Background Technology

[0002] For high-precision medical devices, they will be displayed in certain venues. During the display, the more comprehensive the perspective, the better the display effect.

[0003] Existing technology publication CN216569270U provides a multi-view display cabinet. This device has a placement slot fixed to the top of one side of the cabinet, with a rotating rod inserted into the bottom of the slot. A control device is fixed to the bottom of the rotating rod, and a rotating disk is located at the top of the rotating rod. A clamping device is fixed to the top of the rotating disk, securing medical devices to the rotating disk. The control device causes the rotating rod to rotate the medical devices on the rotating disk, achieving omnidirectional display. Although this device can rotate medical devices, it only allows viewing from one angle. Viewing from other angles, such as the outer wall, is not possible, resulting in poor display quality. Considering that the displayed information is essentially the same regardless of the viewing angle, while ensuring consistent information for visitors in different positions, a single viewing angle often fails to capture visitors' attention or extend their viewing time. This is a significant drawback for product promotion and sales. Therefore, we propose a multi-view display cabinet and its display method. Summary of the Invention

[0050] Example 1

[0051] Please see Figure 1-5 The present invention provides a technical solution:

[0052] A multi-view display case, including

[0053] Display stand 1, with a glass protective cover 2 fixedly installed on one side of display stand 1 to prevent visitors from touching the equipment without affecting the display;

[0054] Connecting box 3 is mounted on the outer wall of display stand 1 by driving a drive to rotate.

[0055] Placement plate 4 is slidably disposed on the outside of connection box 3;

[0056] Turntable 5 is rotated and positioned on one side of placement plate 4. The instrument is limited and fixed on the outside of turntable 5 by clamping assembly 6.

[0057] In this technical solution, the medical devices on the outside of the connecting box 3 and the placement plate 4 can be swung by the drive mechanism. The swing amplitude can be adjusted according to the size of the display case. During the swing, the placement plate 4 can slide along the surface of the connecting box 3 to adjust the display height. The turntable 5 drives the medical devices to rotate. That is, when displaying the medical devices inside the display case, the above different movements can be combined at will to form a variety of movement display methods. Visitors can view the medical devices from multiple perspectives such as looking down, looking up, looking straight ahead, looking near, and looking far away, avoiding the limitation of only being able to view them from one angle and improving the display effect.

[0058] Furthermore, such as Figure 2 As shown, the drive includes a first fixed frame 7 fixedly installed inside the connecting box 3, and one end of the first fixed frame 7 is coaxially fixedly connected to a first motor fixedly installed on the outer wall of the display base 1 via a shaft;

[0059] At least one guide rail 8 is fixedly installed on the outer wall of the connecting box 3. The guide rail 8 is arranged in an arc structure. The outer wall of the display seat 1 is provided with a guide groove 9. The guide groove 9 is arranged in a circular structure and slides with the guide rail 8.

[0060] In this technical solution, with the sliding limit cooperation of the guide rail 8 and the guide groove 9, the first motor drives one end of the first fixed frame 7 to rotate, which in turn drives the connecting box 3 and the placement plate 4 to swing.

[0061] Furthermore, combining Figure 2 and Figure 3 As you can see, a bevel gear A10 is rotatably mounted on one side of the first fixed frame 7, and a sleeve 11 is fixedly mounted on one side of the bevel gear A10. The sleeve 11 extends through the interior of the first fixed frame 7 and the display base 1 to the outside and is fixedly connected to the outer wall of the display base 1. The bevel gear A10 is coaxial with one end of the first fixed frame 7 and is slidably connected to its axis.

[0062] A bevel gear A10 is meshed with a bevel gear B12 on its outer side. A connecting shaft 13 is fixedly installed in the middle of the bevel gear B12. An adjusting shaft 14 is installed at one end of the connecting shaft 13. A bevel gear C15 is fixedly installed at one end of the adjusting shaft 14. A bevel gear D16 is meshed with the outer wall of the bevel gear C15. The bevel gears D16 and C15 are limited by the second fixing block 17.

[0063] The shaft of the bevel gear D16 passes through the second fixing block 17 and the inner wall of the connecting box 3, extends to the outside, and is connected and fixed to the outer wall of the placement plate 4.

[0064] In this technical solution, since the bevel gear A10 is fixedly connected to the display stand 1 through the first fixed frame 7, when the first motor drives one end of the first fixed frame 7 to rotate, the bevel gear A10 remains stationary. At this time, the first fixed frame 7 drives the connecting shaft 13 on one side to swing along through the connecting handle, and the bevel gear B12 at one end of the connecting shaft 13 rotates around the bevel gear A10, thereby driving the connecting shaft 13 and the adjusting shaft 14 to rotate simultaneously. Under the meshing transmission action of the bevel gear C15 and the bevel gear D16, the placement plate 4 is driven to rotate and adjust its orientation, so that it can always be horizontal. The design of the above structure can ensure that the orientation of the placement plate 4 is always adjusted to a horizontal position during the movement, and there will be no situation where the angle is tilted and the instrument falls.

[0065] Furthermore, see Figure 3 The outer wall of the first fixing frame 7 is provided with a sliding groove 18, and the sliding groove 18 is slidably connected to one end of the second fixing block 17;

[0066] At least one keyway 19 is provided at one end of the connecting shaft 13. A flat key 20 is slidably disposed inside the keyway 19 and is fixedly disposed on the outer wall of the adjusting shaft 14.

[0067] A telescopic rod A21 is fixedly installed on one side of the first fixed frame 7, and the output end of the telescopic rod A21 is connected and fixed to the outer wall of the second fixed block 17.

[0068] In this technical solution, during the movement of the placement plate 4, the telescopic rod A21 extends and retracts, causing the placement plate 4 to rise and fall, adapting to the height of different visitors and providing them with a variety of viewing angles. The telescopic rod A21 allows the placement plate 4 to be further raised or lowered, accommodating people of different heights and ensuring they all have a good viewing experience and perspective.

[0069] It is worth noting that, such as Figure 4 As shown, a rotating groove 22 is provided inside the placement plate 4. The rotation drive includes a worm gear 23 that is rotatably disposed inside the rotating groove 22. The rotating shaft of the worm gear 23 is coaxially and fixedly connected to the shaft of the turntable 5.

[0070] The outer wall of the worm gear 23 is meshed with a worm 24, and one end of the worm 24 is coaxially and fixedly connected to the second motor 25, which is fixedly installed in the placement plate 4.

[0071] In this technical solution, the instrument is placed on the turntable 5. The output shaft of the second motor 25 rotates, causing the worm gear 24 to rotate. This, in turn, rotates the worm wheel 23 meshing with the worm gear 24, which in turn rotates the turntable 5, allowing the instrument to change its position and angle. This rotational drive allows the medical instrument to rotate simultaneously with the changing viewing angle, providing more angles for displaying the instrument and further enhancing the presentation effect.

[0072] It is worth noting that, such as Figure 4 As shown, the turntable 5 has a clamping groove 26 inside. The clamping assembly 6 includes a drive block 27 rotatably disposed inside the clamping groove 26. The drive block 27 has a square structure. A support rod 28 is rotatably disposed at the corner of the drive block 27 via a pin. A clamping seat 29 is rotatably disposed at the outer end of the support rod 28 via a pin. The clamping seat 29 is slidably connected to the groove on the outer side of the turntable 5. A transmission gear 32 is coaxially fixedly disposed on one side of the drive block 27. A rack 33 is meshed with the outer wall of the transmission gear 32. A telescopic rod B34 is fixedly disposed at one end of the rack 33. The telescopic rod B34 is fixedly disposed on the inner wall of the clamping groove 26.

[0073] In this technical solution, the telescopic rod B34 is extended and retracted by the controller, which in turn moves the rack 33. Under the meshing transmission action of the rack 33 and the transmission gear 32, the transmission gear 32 and the drive block 27 rotate. The rotation of the drive block 27 pulls the support rod 28. Since the clamping seat 29 and the turntable 5 are slidably connected, the pull of the drive block 27 on the support rod 28 can cause multiple clamping seats 29 to retract inward simultaneously, limiting the outer wall of the device. The clamping assembly 6 can stabilize the medical device, and the multiple clamping seats can fix the outer wall of the medical device at multiple points, ensuring stable movement during the switching of viewing angles, and also providing protection for the medical device itself.

[0074] In addition, such as Figure 5 As shown, a clamping head 30 is slidably disposed on one side of the clamping seat 29, and a spring 31 is fixedly disposed at one end of the clamping head 30. One end of the spring 31 is connected and fixed to the inner wall of the clamping seat 29.

[0075] In this technical solution, the spring 31 allows the clamping head 30 to have a certain degree of elasticity, providing a certain buffering and protective effect for the device itself.

[0076] When the multi-view display cabinet is needed, first, the instrument is placed on the turntable 5. At this time, the telescopic rod B34 is driven to extend and retract by the controller, which drives the rack 33 to move, thereby driving the transmission gear 32 to rotate. This causes the drive block 27 to rotate and pull the support rod 28, so that the clamping seat 29 can limit the outer wall of the instrument. The spring 31 allows the clamping head 30 to have a certain elasticity, which provides a certain buffering and protection for the device itself.

[0077] At this time, the first motor drives the first fixed frame 7 and the connecting box 3 to rotate. Since the bevel gear A10 is fixed on the display base 1, as the connecting box 3 rotates around the bevel gear A10, the bevel gear B12 will mesh with the bevel gear A10, which will cause the bevel gear C15 to mesh with the bevel gear D16, thereby causing the output shaft of the bevel gear D16 to rotate, that is, the placement plate 4 will rotate to adjust its position so that it can always be horizontal.

[0078] During this process, the extension and retraction of the drive telescopic rod A21 can cause the placement plate 4 to be raised and lowered during the switching process to adapt to different people's heights;

[0079] At the same time, the output shaft of the second motor 25 can be driven to rotate, which in turn drives the worm gear 24 to rotate, thereby causing the worm wheel 23 meshing with the worm gear 24 to rotate, which in turn drives the turntable 5 to rotate, thus allowing the instrument to switch its rotation position angle.

[0080] Example 2

[0081] See Figure 1-5 The present invention provides a display method for a multi-view display cabinet, which allows the display cabinet to select a display mode according to the structure and usage characteristics of the displayed items.

[0082] First, the instrument is placed on the turntable 5. The controller drives the telescopic rod B34 to extend and retract, which in turn moves the rack 33. Under the meshing transmission action of the rack 33 and the transmission gear 32, the transmission gear 32 and the drive block 27 are rotated. The rotation of the drive block 27 pulls multiple support rods 28, causing multiple clamping seats 29 to retract inward synchronously to limit and clamp the outer wall of the instrument.

[0083] The exhibits can be categorized into the following types for display:

[0084] 1) When the information to be displayed is mainly concentrated inside the instrument, it can be simply displayed by raising and lowering the placement plate 4. In this case, it is only necessary to drive the telescopic rod A21 to extend and retract to raise and lower the placement plate 4. Alternatively, it can be displayed by swinging the placement plate 4. In this case, the first motor drives the first fixed frame 7 to rotate around one end, causing the connecting box 3 and the placement plate 4 to swing the instrument around the axis of the first fixed frame 7. The bevel gear B12 rotates around the bevel gear A10 to drive the connecting shaft 13 and the adjusting shaft 14 to rotate while swinging. Under the meshing transmission of the bevel gear C15 and the bevel gear D16, the placement plate 4 is driven to rotate and adjust its position so that it can always be horizontal. Alternatively, both of the above display methods can be performed simultaneously.

[0085] 2) When the information to be displayed is mainly focused on the circumferential surface of the instrument, it can be simply displayed by rotating the turntable 5. At this time, the output shaft of the second motor 25 is driven to rotate, which drives the worm gear 24 to rotate, causing the worm wheel 23 meshing with the worm gear 24 to rotate, which drives the turntable 5 and the instrument held on it to rotate and switch angles. Alternatively, the placement plate 4 can be swung while the turntable 5 is rotated to form a multi-view display, that is, the first motor and the second motor 25 are driven to work at the same time.

[0086] 3) When displaying diverse and complex information or other situations, the display method of swinging the placement plate 4 can be directly selected. In this case, only the first motor needs to be driven. Alternatively, the placement plate 4 can be raised and lowered while swinging. In this case, the first motor and the telescopic rod A21 need to be driven simultaneously. Alternatively, the turntable 5 can be rotated while swinging the placement plate 4. In this case, the first motor and the second motor 25 need to be driven simultaneously. Alternatively, the placement plate 4 can be raised and lowered while swinging and the turntable 5 can be rotated simultaneously. In this case, the first motor, the telescopic rod A21, and the second motor 25 need to be driven simultaneously.

[0087] 4) When the displayed information is difficult to classify into the above three categories, it is classified into other categories. In this case, only the display method of swinging the placement plate 4 is selected, that is, only the first motor is driven to work.
