Description

Technical Field

[0001] The present application relates to the technical field of model display, and particularly to a model stand. Background Art

[0002] A model stand is a cabinet used to display achievements, models, etc. When displaying exhibits, a display stand is often used to comprehensively display three-dimensional model exhibits.

[0003] When using a model stand to display exhibits, for the convenience of people to view the exhibits comprehensively, the model stand for displaying exhibits is often liftable and rotatable. At the same time, for the convenience of people to clearly view the exhibits, lamps will be added to the model stand. By irradiating the exhibits, the brightness of the environment where the exhibits are located is increased, so that people can clearly and conveniently view the exhibits.

[0004] When the irradiation range of the lamp is relatively wide, the light at the exhibit is the same as the surrounding light, resulting in difficulty in highlighting the characteristics and highlights of the exhibit and attracting people to view the exhibit quickly. For this reason, a spotlight is usually additionally provided to locally irradiate the exhibit, so that the light intensity at the exhibit is higher than the surrounding light intensity.

[0005] Regarding the above related technologies, the irradiation range of the spotlight is limited. When the size and specification of the exhibit are relatively large, after the spotlight irradiates the exhibit, the brightness in the middle of the exhibit is bright and the brightness at the edge is dim, making it impossible for people to clearly and conveniently view the exhibit. Summary of the Invention

[0006] In order to improve the problem that the brightness at the edge of the exhibit is dim after being irradiated by the spotlight, resulting in people being unable to clearly and conveniently view the exhibit, the present application provides a model stand.

[0007] The model stand provided by the present application adopts the following technical solutions:

[0008] A model stand includes a cabinet body and a spotlight. A display stand for placing exhibits is movably arranged on the cabinet body. The spotlight is located on the cabinet body and irradiates towards the display stand. An adjusting mechanism for adjusting the distribution of the light of the spotlight on the display stand is arranged on the cabinet body.

[0009] By adopting the above technical solutions, the exhibit is placed on the cabinet body through the display stand, and the spotlight irradiates the exhibit on the display stand. Then, the position of the display stand is adjusted to facilitate people to view the exhibit from multiple angles. As the display angle of the exhibit changes, the irradiation range of the spotlight on the exhibit also changes; to enable people to clearly view the exhibit, the adjusting mechanism is activated, and the adjusting mechanism adjusts the distribution of the light of the spotlight; so that as the display angle of the exhibit changes, through the adjustment of the adjusting mechanism, the brightness at the edge of the exhibit will not be dim, ensuring that people can clearly and conveniently view the exhibit.

[0010] Optionally, the adjusting mechanism includes a mounting frame located above the exhibition stand, a plurality of lens bodies located within the mounting frame, a telescopic member for connecting two adjacent lens bodies, and an adjusting assembly for pulling the telescopic member to expand and contract.

[0011] The plurality of lens bodies are horizontally distributed in a straight line. The adjusting assembly is located on the mounting frame. Connectors are provided on both of the lens bodies at the two ends. One of the connectors is fixedly connected to one end of the mounting frame away from the adjusting assembly, and the other end is connected to the adjusting assembly.

[0012] By adopting the above technical solution, the plurality of lens bodies are installed above the exhibition stand through a mounting frame. The light emitted by the spotlight is converged by the lens bodies and irradiated onto the exhibit. When there is a problem of dim light at the edge of the exhibit, the adjusting assembly is activated. The adjusting assembly pulls the lens bodies to move horizontally through the connectors, so that the telescopic member expands and contracts, and further realizes the adjustment of the distance between two adjacent lens bodies. When the distance between two adjacent lens bodies becomes larger, the distance between the converging points of the two adjacent lens bodies becomes larger; at this time, the light emitted by the spotlight is converged by the lens bodies and irradiated onto the exhibit at a more dispersed position, so that the light converged by the lens bodies at the ends is irradiated onto the exhibit near the edge of the exhibit, thereby improving the brightness at the edge of the exhibit and ensuring that people can clearly and conveniently view the exhibit.

[0013] Optionally, the adjusting assembly includes a roller rotatably mounted on the mounting frame and a power source for driving the roller to rotate. The length direction of the roller is perpendicular to the distribution direction of the plurality of lens bodies. One end of one of the connectors away from the lens body is fixedly connected to the roller.

[0014] By adopting the above technical solution, the power source is activated, and the power source drives the roller to rotate on the mounting frame, so as to realize the winding of the connector. The wound connector pulls the lens body to move closer to the roller, so that the telescopic member is stretched, and thus the distance between two adjacent lens bodies is adjusted.

[0015] Optionally, the telescopic member is provided as a transparent elastic tape, and the elastic tape is detachably connected to the lens body.

[0016] By adopting the above technical solution, the elastic tape has a certain elasticity, which not only facilitates the rapid adjustment of the distance between two adjacent lens bodies, but also enables the two adjacent lens bodies to always be in the same plane, which helps the lens bodies to always be in a horizontal state, and further better converges the light emitted by the spotlight.

[0017] Optionally, the installation frame is arranged on the exhibition stand in a lifting and sliding manner, and a lifting mechanism for driving the installation frame to lift and slide is arranged on the cabinet body.

[0018] By adopting the above technical solution, the lifting mechanism can adjust the distance between the installation frame and the exhibition stand. When the angle of the exhibition stand changes, the lifting mechanism is started, and the lifting mechanism adjusts the height of the installation frame so that the focus of the lens body on the installation frame is located on the exhibit on the exhibition stand, thereby improving the brightness of the light on the exhibit and ensuring that personnel can clearly and conveniently view the exhibit.

[0019] Optionally, the adjusting mechanism further includes a connecting ring for slidably carrying the installation frame and a sliding assembly for driving the installation frame to slide in the radial direction of the connecting ring. The light projected by the spotlight is located inside the connecting ring. A plurality of installation frames are arranged, and the plurality of installation frames are arranged at intervals in the circumferential direction of the connecting ring. A plurality of the lens bodies in the same installation frame are distributed in the radial direction of the connecting ring.

[0020] By adopting the above technical solution, a plurality of installation frames are slidably installed on the connecting ring. When the light on the exhibit is relatively dim, the sliding assembly is started, and the sliding assembly drives the installation frame to move towards the center direction of the connecting ring inside the connecting ring, so that the number of lens bodies located inside the connecting ring becomes larger; after the number of lens bodies entering the connecting ring becomes larger, a plurality of lens bodies can converge the light emitted by the spotlight onto the exhibit, thereby improving the brightness of the light on the exhibit.

[0021] Optionally, the sliding assembly includes a rack for connecting the installation frame, a plurality of gears meshed with the plurality of racks one by one, an internal gear ring meshed with the plurality of gears, and a driving member for driving the gears to rotate;

[0022] The internal gear ring and the plurality of gears are all rotatably installed on the connecting ring, and the plurality of gears are all meshed inside the internal gear ring;

[0023] When the driving member drives the gears to rotate, the gears push the installation frame to slide in the radial direction of the connecting ring through the racks.

[0024] By adopting the above technical solution, when it is necessary to drive the installation frame to slide, only the driving member needs to be started. The driving member drives the plurality of gears and the internal gear ring to rotate. The rotating gears drive the racks to slide in the radial direction of the connecting ring on the connecting ring, and the racks push the installation frame to slide in the radial direction of the connecting ring on the connecting ring, thereby adjusting the number of lens bodies located inside the connecting ring, and further realizing the adjustment of the brightness of the light on the exhibit.

[0025] Optionally, a limiting assembly for restricting the yaw of the rack on the connecting ring is arranged on the connecting ring.

[0026] By adopting the above technical solution, the limiting component restricts the rack from rotating together with the gear, enabling the gear to stably drive the rack to slide on the connecting ring, achieving the effect of quickly adjusting the brightness of the light on the exhibit.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. As the display angle of the exhibit changes, the irradiation range of the spotlight on the exhibit also changes; to enable people to clearly view the exhibit, the adjustment mechanism is activated, and the adjustment mechanism adjusts the distribution of the spotlight light; so that as the display angle of the exhibit changes, through the adjustment of the adjustment mechanism, the brightness at the edge of the exhibit will not dim, ensuring that people can clearly and conveniently view the exhibit;

[0029] 2. When the angle of the exhibition stand changes, the lifting mechanism is activated, and the lifting mechanism adjusts the height of the mounting frame, so that the focus of the lens body on the mounting frame is located on the exhibit on the exhibition stand, thereby achieving the effect of increasing the brightness of the light on the exhibit and ensuring that people can clearly and conveniently view the exhibit;

[0030] 3. When the light on the exhibit is relatively dim, the sliding component is activated, and the sliding component drives the mounting frame to move towards the center direction of the connecting ring in the connecting ring, increasing the number of lens bodies located within the connecting ring; after the number of lens bodies entering the connecting ring increases, multiple lens bodies can converge the light emitted by the spotlight onto the exhibit, thereby increasing the brightness of the light on the exhibit.

Detailed implementation mode

[0037] The following further elaborates on this application in conjunction with the attached Figures 1-5 drawings.

[0038] An embodiment of this application discloses a model stand. Refer to Figure 1 , a model stand includes a cabinet body 1 and a spotlight 2. The cabinet body 1 can be frustum-shaped or prismatic. In the embodiment of this application, the cabinet body 1 is set as a hollow prismatic shape, and the longitudinal section of the cabinet body 1 is an isosceles trapezoid. The spotlight 2 is erected above the cabinet body 1 through a support plate, and a plurality of spotlights 2 are provided. The plurality of spotlights 2 are arranged at intervals around the central axis of the cabinet body 1. In the embodiment of this application, four spotlights 2 are provided. An exhibition stand 3 is movably arranged on the cabinet body 1. The number of the exhibition stands 3 is the same as the number of the spotlights 2, and the spotlight 2 is located above the exhibition stand 3, and the spotlight 2 irradiates towards the exhibition stand 3. In order to enable the exhibition stand 3 to deflect in any direction on the cabinet body 1, a spherical hinge seat 10 for spherical hinge connection with the exhibition stand 3 is arranged on the cabinet body 1.

[0039] After the exhibit is placed on the exhibition stand 3, rotate the exhibition stand 3 so that the exhibit rotates synchronously with the exhibition stand 3, which is convenient for personnel to view the exhibit from multiple directions. As the display angle of the exhibit changes, the irradiation range of the spotlight 2 on the exhibit also changes. In order to enable personnel to clearly view the exhibit, refer to Figure 1 and Figure 2 , an adjusting mechanism 4 for adjusting the distribution of the light of the spotlight 2 on the exhibition stand 3 is arranged on the cabinet body 1. The adjusting mechanism 4 includes a plurality of connecting rings 45 located above the exhibition stand 3, a plurality of mounting frames 41 slidably arranged on the connecting rings 45, a plurality of lens bodies 42 located in the mounting frames 41, a telescopic member 43 for connecting adjacent two lens bodies 42, an adjusting assembly 44 for pulling the telescopic member 43 to extend and retract, and a sliding assembly 46 for driving the mounting frame 41 to slide along the radial direction of the connecting ring 45. Since both the exhibition stand 3 and the spotlight 2 are provided with four, four connecting rings 45 are also provided, and the four connecting rings 45 correspond to the four spotlights 2 one by one; the connecting ring 45 is located between the spotlight 2 and the exhibition stand 3, and the light projected by the spotlight 2 is located within the connecting ring 45.

[0040] Refer toFigure 2 and Figure 3 A plurality of mounting frames 41 located on the same connecting ring 45 are arranged at intervals in the circumferential direction of the connecting ring 45. The number of mounting frames 41 on each connecting ring 45 can be two, three, four, five... In the embodiment of the present application, the number of mounting frames 41 on each connecting ring 45 is set to four, and the four mounting frames 41 are evenly distributed on the connecting ring 45. The length direction of the mounting frame 41 is consistent with the advancing direction of the connecting ring 45, and the mounting frame 41 is slidably arranged along the advancing direction of the connecting ring 45.

[0041] Refer to Figure 2 and Figure 3 As shown in FIGS. and, the convex surface of the lens body 42 faces the exhibition stand 3. The lens body 42 is located in the mounting frame 41, and a plurality of lenses are horizontally spaced apart along the length direction of the mounting frame 41. The telescopic member 43 can be a spring, an elastic cord, or an elastic tape; in order to make full use of the light of the spotlight 2 in the embodiment of the present application, the telescopic member 43 is set as a transparent elastic tape. Wedge-shaped strips are bonded to both ends of the elastic tape, and wedge-shaped grooves adapted to the wedge-shaped strips are formed on the side of the lens body 42. Under the clamping action of the wedge-shaped strips and the wedge-shaped grooves, the elastic tape is detachably connected to the lens body 42.

[0042] Refer to Figure 2 and Figure 3 As shown in FIGS. and, the adjusting assembly 44 is located on the mounting frame 41. The adjusting assembly 44 includes a roller 441 rotatably mounted on the mounting frame 41 and a power source 442 for driving the roller 441 to rotate. The length direction of the roller 441 is perpendicular to the direction in which the plurality of lens bodies 42 are distributed, and a part of the roller 441 is located in the mounting frame 41. The power source 442 is set as a motor, and the motor is mounted on the mounting frame 41, and the motor drives the roller 441 to rotate forward and backward on the mounting frame 41. Among the plurality of lens bodies 42 on the same mounting frame 41, connectors 5 are provided on the lens bodies 42 at both ends. The connectors 5 can be straps or tapes. In the embodiment of the present application, the connectors 5 are set as straps. One of the straps is fixedly tied to one end of the mounting frame 41 away from the adjusting assembly 44, and the other end is tied to the roller 441.

[0043] The light emitted by the spotlight 2 passes through the inner ring of the connecting ring 45, and the light is converged by the lens body 42 and then irradiated onto the exhibit. When there is a problem of dim light at the edge of the exhibit, the adjustment component 44 is activated. The adjustment component 44 drives the lens body 42 to move towards the direction close to the adjustment component 44 through the strap. At this time, the elastic tape is stretched, and the distance between adjacent lens bodies 42 becomes larger. At this time, the light emitted by the spotlight 2 is converged by the lens body 42 and irradiated onto the exhibit at a more scattered position; the light converged by the lens body 42 at the end is irradiated onto the exhibit near the edge of the exhibit, thereby improving the brightness at the edge of the exhibit and ensuring that people can clearly and conveniently view the exhibit.

[0044] Since the number of lens bodies 42 located inside the connecting ring 45 will also affect the utilization degree of the light of the spotlight 2 by the lens body 42, and then realize the adjustment of the light intensity at the exhibit. Therefore, the sliding component 46 can drive the mounting frame 41 to slide along the radial direction of the connecting ring 45, thereby adjusting the number of lens bodies 42 located inside the connecting ring 45. Refer to Figure 2 and Figure 4 , the sliding component 46 includes a rack 461 for connecting the mounting frame 41, a plurality of gears 462 meshed with the plurality of racks 461 one by one, an internal gear ring 463 meshed with the plurality of gears 462, and a driving member 464 for driving the gears 462 to rotate; since there are four mounting frames 41, there are four racks 461 and gears 462; the four gears 462 are evenly distributed at intervals along the circumferential direction of the connecting ring 45, and the gears 462 are rotatably mounted on the connecting ring 45 through a rotating shaft. The internal gear ring 463 is rotatably mounted on the connecting ring 45, and the four gears 462 are all meshed with the inner teeth of the internal gear ring. The rack 461 is slidably arranged on the connecting ring 45 along the radial direction of the connecting ring 45, and one side of the rack 461 is meshed with the gear 462. The mounting frame 41 is welded and fixed to the rack 461, and the mounting frame 41 is located on the side of the rack 461 away from the gear 462. The driving member 464 is set as a servo motor, and the servo motor is installed on the side of the connecting ring 45 away from the gear 462, and the servo motor drives one of the gears 462 to rotate on the connecting ring 45.

[0045] When it is necessary to adjust the number of lens bodies 42 located within the connection ring 45, it is only necessary to start the servo motor. The servo motor drives one of the gears 462 to rotate. The rotating gear 462 drives the internal gear ring to rotate on the connection ring 45, and the rotating internal gear ring drives the other gears 462 to rotate synchronously. At this time, the four gears 462 respectively drive the four racks 461 to slide on the connection ring 45 in the radial direction of the connection ring 45, thereby driving the mounting frame 41 to slide on the connection ring 45 and adjusting the number of lens bodies 42 located within the connection ring 45. When the number of lens bodies 42 located within the connection ring 45 increases, the multiple lens bodies 42 can sufficiently converge the light irradiated into the connection ring 45, thereby increasing the brightness level at the exhibition item location.

[0046] To achieve rapid adjustment of the number of lens bodies 42 within the connection ring 45, referring to Figure 2 and Figure 4 , a limiting component 7 for restricting the yaw of the rack 461 on the connection ring 45 is provided on the connection ring 45. The limiting component 7 includes a retaining ring 71 and a limiting rod 72. The retaining ring 71 is coaxially mounted and fixed on the connection ring 45. The rack 461, the gear 462, and the internal gear ring 463 are all located between the retaining ring 71 and the connection ring 45. Four limiting rods 72 are provided, and the four limiting rods 72 correspond to the four racks 461 one by one. The four limiting rods 72 all pass through the retaining ring 71 and are welded and fixed to the retaining ring 71. The end of the limiting rod 72 away from the rack 461 is cylindrical, and the cross-section of the end close to the rack 461 is non-circular. In the embodiment of the present application, the cross-section of the end of the limiting rod 72 close to the rack 461 is set as square. A limiting groove 9 for the sliding insertion of the limiting rod 72 is provided on the side surface of the rack 461 close to the retaining ring 71.

[0047] Since the lens body 42 will converge the light emitted by the spotlight 2 to its focal point, when the exhibition item is located at the focal point of the lens body 42, the brightness level at the exhibition item location is the brightest; when the focal point of the lens body 42 is farther away from the exhibition item, the brightness level on the exhibition item is lower, and at the same time, the illuminated range on the exhibition item is larger. Therefore, referring to Figure 1 and Figure 5 , a lifting mechanism 6 for driving the connection ring 45 to lift and slide is provided on the cabinet body 1. The lifting mechanism 6 includes a support cylinder 62 vertically installed in the middle of the cabinet body 1, a screw rod 63 rotatably installed in the support cylinder 62, a driving motor 61 for driving the screw rod 63 to rotate, a collar 64 sleeved on the support cylinder 62, and a support rod 65 for fixedly connecting the connection ring 45 to the collar 64.

[0048] Referring to Figure 1 and Figure 5, one end of the support cylinder 62 is communicatively connected to the cavity of the cabinet body 1, and a support disk 11 is fixedly welded to the other end. The spotlight 2 is installed on the support disk 11. The driving motor 61 is installed in the cavity of the cabinet body 1, and the driving motor 61 drives the screw rod 63 to rotate in the support cylinder 62. A sliding groove 8 is formed in the side wall on one side of the support cylinder 62, and the length direction of the sliding groove 8 is the same as the length direction of the screw rod 63; a nut seat is integrally formed on the inner wall of the collar 64, and the nut seat passes through the sliding groove 8 and is threadedly sleeved on the screw rod 63; the width dimension of the nut seat is the same as the width dimension of the sliding groove 8. Four support rods 65 are provided, and the four support rods 65 correspond to the four connecting rings 45 one by one, and the four support rods 65 are evenly distributed along the circumferential direction of the support cylinder 62, and the support rods 65 are arranged along the radial direction of the support cylinder 62.

[0049] Start the driving motor 61, and the driving motor 61 drives the screw rod 63 to rotate. The screw rod 63 drives the connecting ring 45 to move up and down and slide in the cabinet body 1 through the collar 64 and the support rod 65, so as to adjust the distance between the exhibits on the exhibition stand 3 and the lens body 42 on the connecting ring 45, thereby changing the brightness level of the exhibits and the size of the illuminated area.

[0050] The implementation principle of the model stand in the embodiment of the present application is as follows: Place the exhibits on the exhibition stand 3 and rotate the exhibition stand 3 so that the exhibits rotate synchronously with the exhibition stand 3, which is convenient for personnel to view the exhibits from multiple directions. When there is a problem of low brightness on the exhibits, the driving motor 61 can be started first. The driving motor 61 drives the connecting ring 45 to move up and down and slide in the cabinet body 1 through the screw rod 63, the collar 64 and the support rod 65, changing the distance between the exhibits and the lens body 42 so that the exhibits are located at the focus of the lens body 42.

[0051] Then start the adjustment assembly 44. The adjustment assembly 44 drives the lens body 42 to move in the direction close to the adjustment assembly 44 through the binding belt. At this time, the elastic tape is stretched, and the distance between adjacent two lens bodies 42 becomes larger. At this time, the light emitted by the spotlight 2 is converged by the lens body 42, and the positions where the light is irradiated onto the exhibits are relatively scattered; the light converged by the lens body 42 at the end irradiates the position on the exhibit close to the edge of the exhibit, thereby improving the brightness level at the edge of the exhibit.

[0052] Finally, start the servo motor. The servo motor drives one of the gears 462 to rotate. The rotating gear 462 drives the internal gear ring to rotate on the connecting ring 45, and the rotating internal gear ring drives the other gears 462 to rotate synchronously. At this time, the four gears 462 respectively drive the four racks 461 to slide on the connecting ring 45 along the radial direction of the connecting ring 45, thereby driving the mounting frame 41 to slide on the connecting ring 45 to adjust the number of lens bodies 42 located inside the connecting ring 45; when the number of lens bodies 42 located inside the connecting ring 45 increases, the multiple lens bodies 42 can fully converge the light irradiated into the connecting ring 45, thereby improving the brightness level at the position of the exhibits.

[0053] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
