Description

Technical Field

[0001] The present application relates to the technical field of exhibition hall lighting, and in particular to an adjustable lighting device for an exhibition hall. Background Art

[0002] Exhibition halls are an important way to display culture, commodities, etc. In order to display relevant information and items in a more organized and comprehensive manner, exhibits need to be arranged in a specific order. Some exhibition halls will be equipped with tour guides to provide guidance and explanations to visitors, so that visitors can visit the exhibits in order under guidance.

[0003] When the lighting devices used for display in the existing exhibition halls illuminate the exhibits, different exhibits require different lighting angles, so the lighting angle also needs to be adjusted. In the prior art, the adjustment is generally performed in a single direction, and the adjustment range is limited, resulting in poor lighting effect, which leads to poor exhibit display effect. Summary of the invention

[0004] In order to improve the display effect of exhibits, the present application provides an adjustable lighting device for an exhibition hall.

[0005] The application provides an adjustable lighting device for an exhibition hall, which adopts the following technical solution: An adjustable lighting device for an exhibition hall comprises a base, a mounting plate rotatably mounted on the base, and a plurality of lighting mechanisms spaced apart on the mounting plate, wherein the lighting mechanisms comprise: A base plate is arranged on the mounting plate; A mounting seat, which is mounted on the base plate by rotating the rotating shaft; The lamp body is rotatably mounted on the mounting seat via a second rotating shaft and is used to illuminate the exhibits, wherein the axes of the second rotating shaft and the first rotating shaft are perpendicular to each other; The driving member is arranged on the base plate and connected to the rotating shaft 1 and / or the rotating shaft 2 through the control mechanism to drive the rotating shaft 1 and / or the rotating shaft 2 to rotate.

[0006] By adopting the above technical solution, the mounting plate rotates to drive multiple lighting mechanisms to rotate, so as to adjust the irradiation position of the lighting mechanisms. At the same time, the control mechanism first controls the driving member to connect with the rotating shaft one and the rotating shaft two, and the driving member drives the mounting seat and the lamp body to rotate, so as to adjust the angle of the lamp body from two mutually perpendicular directions for coarse adjustment. Then, as needed, the control mechanism controls the driving member to connect with the rotating shaft one or the rotating shaft two, and again fine-adjusts the angle of the lamp body as needed, so that the irradiation position and angle of the lamp body can meet the required requirements. Therefore, the irradiation of the lamp body can be adjusted from three directions, thereby improving the display effect of the exhibits.

[0007] By installing the disk, coarse adjustment and fine adjustment, the time spent on adjustment can be greatly saved, the adjustment efficiency can be improved, and subsequent adjustments can be made as needed, thus greatly improving the adjustment effect during adjustment. At the same time, the adjustment efficiency and effect during adjustment are improved, and the display effect of the exhibits is improved.

[0008] Optionally, the control mechanism includes: A control shaft, arranged on the output shaft of the driving member; A bevel gear 1 is rotatably arranged on a rotating shaft 1 and is coaxially provided with a sliding sleeve; Bevel gear two is disposed on rotating shaft two and meshed with bevel gear one; A connecting assembly, which is slidably arranged on the control shaft and is used to realize simultaneous rotation of the control shaft and the sliding sleeve and / or the rotating shaft after they are connected; A positioning assembly, which is slidably arranged on the sliding sleeve and is used to position or unlock the bevel gear 1 and / or the rotating shaft 1; The moving component is used to drive the connecting component and the positioning component to move.

[0009] By adopting the above technical solution, the moving component starts to drive the connecting component and the positioning component to move, the connecting component connects the control shaft with the rotating shaft one, and the positioning component positions the sliding sleeve and the bevel gear one. At this time, the bevel gear one does not rotate, and the driving member drives the control shaft to rotate. The control shaft rotates to drive the mounting seat and the rotating shaft two to rotate around the axis of the rotating shaft one. Since the bevel gear one is positioned, the bevel gear two and the rotating shaft two rotate around the axis of the rotating shaft two, that is, the rotating shaft one and the rotating shaft two rotate at the same time.

[0010] When only the rotating shaft one needs to rotate, the connecting component connects the control shaft with the sliding sleeve and the rotating shaft one at the same time, and the positioning component unlocks the rotating shaft one and the sliding sleeve, that is, the bevel gear one, the bevel gear two, and the mounting seat all rotate around the rotating shaft one direction, so that the rotating shaft one rotates and the rotating shaft two does not rotate. When only the rotating shaft two needs to rotate, the connecting component connects the control shaft with the sliding sleeve, and at this time, the control shaft rotates to drive the rotating shaft two to rotate; after the rotation is completed, the positioning component positions the sliding sleeve, the bevel gear one and the rotating shaft one, so as to realize driving the rotating shaft one and / or the rotating shaft two to rotate as needed, making the whole process simple, fast and stable, improving the adjustment efficiency and effect, and improving the display effect of the exhibits.

[0011] The cooperation between bevel gear one and bevel gear two can realize the adjustment of the driving direction, so that the power directions of driving shaft one and shaft two are parallel, and the positioning component and the connecting component can be moved in the same direction to realize the adjustment and positioning of the rotation of driving shaft one or shaft two, making the adjustment process faster and more stable, improving the adjustment efficiency and effect, and at the same time, by driving the positioning component and the connecting component at the same time by the moving component, the efficiency and effect can be further improved.

[0012] Optionally, the connection component includes: A connecting sleeve is slidably disposed on the control shaft and rotates simultaneously with the control shaft, the connecting sleeve is connected to the moving component and has a plurality of connecting grooves arranged in a circular array around the axis of the control shaft; Multiple connecting pieces 1 and multiple connecting pieces 2 are respectively arranged on the rotating shaft 1 and the sliding sleeve and can be plugged and installed on the multiple connecting grooves for positioning. The moving component starts to drive the connecting sleeve to move, so that the multiple connecting pieces 1 and multiple connecting pieces 2 are plugged and matched with the multiple connecting grooves individually or simultaneously for positioning. When the multiple connecting pieces 1 are plugged and matched with the multiple connecting grooves individually, the positioning component can position the sliding sleeve or position the sliding sleeve and the rotating shaft 1 simultaneously.

[0013] By adopting the above technical solution, the moving component starts to drive the connecting sleeve and the positioning component to move, so that when only multiple connecting pieces 2 are plugged into the connecting grooves, the positioning component unlocks the sliding sleeve and the bevel gear 1, and the control shaft rotation can drive the bevel gear 1, the bevel gear 2 and the rotating shaft 2 to rotate, that is, only the rotating shaft 2 is driven to rotate and the rotating shaft 1 does not rotate; the moving component continues to start the driving connecting sleeve and the positioning component to move, so that multiple connecting pieces 1 and multiple connecting pieces 2 are all plugged into the connecting grooves, the positioning component continues to unlock the sliding sleeve and the bevel gear 1, the control shaft rotation drives the rotating shaft 1 to rotate, and the mounting seat, the bevel gear 1 and the bevel gear 2 all rotate around the axis of the rotating shaft 1, that is, only the rotating shaft 1 is driven to rotate and the rotating shaft 2 does not rotate.

[0014] The moving component continues to start driving the connecting sleeve and the positioning component to move, so that only the multiple connecting pieces 1 are plugged into the connecting grooves, and the positioning component positions the sliding sleeve and the bevel gear 1 so that they cannot rotate. The control shaft can drive the rotating shaft 1, the mounting seat and the bevel gear 2 to rotate around the axis of the rotating shaft 1. Since the bevel gear 1 cannot rotate, the rotating shaft 1 and the rotating shaft 2 can both rotate, that is, the rotating shaft 1 and the rotating shaft 2 are driven to rotate at the same time.

[0015] After the rotation is completed, the moving component continues to start driving the connecting sleeve and the positioning component to move, so that only the multiple connecting pieces continue to be plugged into the connecting grooves, the positioning component continues to position the bevel gear, and the positioning component positions the sliding sleeve and the rotating shaft at the same time, thereby greatly improving the stability of adjustment during operation, making the adjustment more efficient and stable, improving the efficiency and effect of the adjustment, and allowing the exhibits to be adjusted to the appropriate angle faster and better, thereby improving the display effect of the exhibits.

Alternatively, when the positioning column is plugged and installed on the base plate and a plurality of positioning blocks are plugged and installed on a plurality of connecting grooves, the sliding sleeve and the rotating shaft can be positioned at the same time.

[0017] By adopting the above technical solution, the moving component starts to drive the positioning sleeve to move, the positioning column is disengaged from the base plate, and the positioning block is disengaged from the connecting groove, thereby unlocking the bevel gear 1 and the rotating shaft 1. As the positioning sleeve and the connecting sleeve move simultaneously, the positioning sleeve first drives multiple positioning columns to approach the base plate, so that the multiple positioning columns are plugged and installed on the base plate, so as to realize the positioning of the sliding sleeve and the bevel gear 1. The positioning sleeve, multiple positioning columns and the connecting sleeve continue to move, so that the multiple positioning blocks are plugged and installed on the multiple connecting grooves for positioning. At this time, the bevel gear 1 and the rotating shaft 1 can be positioned simultaneously.

After the positioning posts are plugged into the substrate, the multiple connecting pieces two are disengaged from the multiple connecting grooves and the multiple connecting pieces one continue to be plugged into and matched with the multiple connecting grooves.

[0021] By adopting the above technical solution, the connecting sleeve and the positioning sleeve are guided during the movement, so that they can slide and fit better after the rotation is completed, and the accuracy during the adjustment process is improved, so that the structure is more stable and compact, and the display effect of the exhibits is improved.

Therefore, the illumination angles of the lamp body and the lamp tube can be adjusted at the same time, so that the lamp body and the lamp tube are close to or away from each other, and the lamp body and the lamp tube can rotate in the same direction or in the opposite direction, which improves the adjustment efficiency and effect, can better realize the illumination of the exhibits, and thus further improves the display effect of the exhibits.

[0039] The driving member 24 is a motor, and the control mechanism 4 includes a control shaft 41. The control shaft 41 is rotatably mounted on the second mounting plate 26 and the axes of the two coincide with the axes of the rotating shaft 1 27. Both ends of the control shaft 41 extend to the upper and lower sides of the second mounting plate 26. The driving member 24 is fixedly mounted on the side wall of the substrate 21 and is located on one side of the control shaft 41. The output shaft of the driving member 24 is vertically arranged upward, and the output shaft of the driving member 24 and the bottom of the control shaft 41 are key-connected with mutually meshing driving gears 33. The driving member 24 starts to drive the control shaft 41 to rotate.

[0040] A manual component 3 is provided on the control shaft 41. When the driving member 24 is damaged, the manual component 3 can drive the control shaft 41 to rotate; the manual component 3 includes a manual disk 31 and a manual rod 32. The manual disk 31 is coaxially fixedly installed on the bottom of the control shaft 41, and the manual rod 32 is eccentrically fixedly installed on the manual disk 31; holding the manual rod 32 drives the manual disk 31 and the control shaft 41 to rotate.

[0041] The control mechanism 4 also includes a bevel gear 42 and a bevel gear 43, a connecting assembly 5, a positioning assembly 6 and a moving assembly 7. The bevel gear 42 is rotatably mounted on the outer wall of the rotating shaft 27 and is located between the mounting seat 22 and the mounting plate 25. A sliding sleeve 44 rotatably mounted on the rotating shaft 27 is coaxially fixed on the lower surface of the bevel gear 42. The sliding sleeve 44 is rotatably mounted on the mounting plate 25 and extends below the mounting plate 25. The rotating shaft 27 is rotatably mounted on the sliding sleeve 44 and extends below the sliding sleeve 44. The bevel gear 43 is key-connected to the rotating shaft 28 and meshes with the bevel gear 42.

[0042] The connecting component 5 is slidably set on the control shaft 41, and the connecting component 5 is used to realize the simultaneous rotation of the control shaft 41 after being connected with the bevel gear 42 and / or the rotating shaft 27; the positioning component 6 is slidably set on the sliding sleeve 44, that is, the positioning component 6 is slidably set on the bevel gear 42, and the positioning component 6 is used to position or unlock the bevel gear 42 and / or the rotating shaft 27.

[0043] The moving component 7 is connected to the connecting component 5 and the positioning component 6 and is used to drive the connecting component 5 and the positioning component 6 to move. The positioning component 6 unlocks the bevel gear 1 42. The connecting component 5 connects the control shaft 41 with the sliding sleeve 44 and the bevel gear 1 42. The control shaft 41 drives the bevel gear 1 42, the bevel gear 2 43 and the rotating shaft 28 to rotate, so that the lamp body 23 rotates around the axis of the rotating shaft 28.

[0044] Alternatively, the connecting component 5 connects the control shaft 41 to the rotating shaft 27 and the bevel gear 42. The control shaft 41 rotates to drive the rotating shaft 27 and the mounting base 22 to rotate. At the same time, the bevel gear 42, the bevel gear 43 and the rotating shaft 28 all rotate around the axis of the rotating shaft 27, so that the lamp body 23 rotates around the axis of the rotating shaft 27.

[0045] Alternatively, the positioning component 6 positions the bevel gear 42, and the connecting component 5 continues to connect the control shaft 41 with the rotating shaft 27. Since the bevel gear 42 is positioned and does not rotate, the control shaft 41 drives the rotating shaft 27, the mounting seat 22, the bevel gear 43 and the lamp body 23 to rotate around the axis of the rotating shaft 27. Since the bevel gear 42 cannot rotate, the bevel gear 43, the rotating shaft 28 and the lamp body 23 all rotate around the axis of the rotating shaft 28, thereby realizing the rotation of the lamp body 23 from two directions perpendicular to each other, so that the lamp body 23 can adjust the illumination angle from two directions perpendicular to each other.

[0046] After the rotation is completed, the positioning assembly 6 is connected to the base plate 21 and the connecting assembly 5 continues to connect the control shaft 41 with the rotating shaft 1 27, thereby positioning the rotating shaft 1 27, and at the same time, the positioning assembly 6 continues to position the bevel gear 1 42, so that the rotating shaft 1 27 and the rotating shaft 2 28 can be positioned.

The control shaft 41 is provided with a plurality of connection strips 56 slidably connected to the connection grooves 54, so that the connection sleeve 51 is slidably mounted on the control shaft 41, and the control shaft 41 rotates to drive the connection sleeve 51 to rotate at the same time, and the connection sleeve 51 is connected to the moving assembly 7. The plurality of connection pieces 1 52 are fixedly mounted on the bottom of the rotating shaft 1 27 and are arranged one-to-one with the plurality of connection grooves 54, and the plurality of connection pieces 2 53 are fixedly mounted on the bottom of the sliding sleeve 44 and are arranged one-to-one with the plurality of connection grooves 54, and the connection piece 1 52 is located below the connection piece 2 53, and the plurality of connection pieces 1 52 and the plurality of connection pieces 2 53 can simultaneously slide and cooperate with the plurality of connection grooves 54, so that the angle does not change during adjustment.

[0048] The positioning assembly 6 includes a positioning sleeve 61, a plurality of positioning columns 62 and a plurality of positioning blocks 63. The positioning sleeve 61 is slidably installed on the outer wall of the sliding sleeve 44, and the sliding sleeve 44 rotates to drive the positioning sleeve 61 to rotate, and the positioning sleeve 61 is connected to the moving assembly 7; a plurality of positioning columns 62 are arranged in a circular array around the axis of the sliding sleeve 44 on the lower surface of the positioning sleeve 61, and after the plurality of positioning columns 62 are moved downward, they can be plugged and installed on the mounting plate 1 25 for positioning, and a plurality of positioning blocks 63 are fixedly installed on the upper surface of the mounting plate 26 and are arranged one-to-one with the plurality of connecting grooves 54.

[0049] Before the multiple positioning columns 62 are plugged and installed on the mounting plate 25, the multiple connecting pieces 1 52 and the multiple connecting pieces 2 53 can be plugged and cooperated with the multiple connecting grooves 54 at the same time for positioning, so that the rotating shaft 27 and the bevel gear 42 can rotate around the axis of the rotating shaft 27; after the positioning columns 62 are slidably plugged and installed on the mounting plate 25, the multiple connecting pieces 2 53 are disengaged from the multiple connecting grooves 54, and the multiple connecting pieces 1 52 continue to be plugged and installed on the multiple connecting grooves 54, so that when the adjustment state is changed, the multiple positioning columns 62, the multiple connecting pieces 1 52 and the multiple connecting pieces 2 53 can all be guided.

[0050] The moving assembly 7 includes a moving block 1 71, a moving block 2 72, and a moving member 73. The moving block 1 71 is rotatably mounted on the outer wall of the positioning sleeve 61, and the moving block 2 72 is rotatably mounted on the outer wall of the connecting sleeve 51. The moving block 1 71 and the moving block 2 72 are connected by a connecting column 74, and the connecting column 74 is vertically slidably penetrated on the mounting plate 1 25; the moving member 73 is an electric push rod, and the moving member 73 is fixedly mounted on the lower surface of the mounting plate 1 25, and the piston rod of the moving member 73 passes through the mounting plate 1 25 and is fixedly connected to the moving block 1 71.

[0051] When the positioning sleeve 61 and the sliding sleeve 44 are at the highest point, the multiple connecting pieces 2 53 are inserted and installed on the multiple connecting grooves 54 for positioning, so that the control shaft 41 is connected to the sliding sleeve 44 and the bevel gear 1 42, and the connecting piece 1 52 located on the rotating shaft 1 27 is located at the avoidance groove 55 and is disengaged from the control shaft 41. At the same time, the multiple positioning columns 62 are located above the mounting plate 1 25, that is, the bevel gear 1 42 is unlocked. At this time, the rotation of the control shaft 41 can only drive the rotating shaft 28 to rotate, that is, it can only drive the lamp body 23 to rotate around the axis of the rotating shaft 28.

[0052] The moving member 73 drives the positioning sleeve 61 and the connecting sleeve 51 to move simultaneously, so that the positioning sleeve 61 and the sliding sleeve 44 move downward at the same time, and the positioning sleeve 61 drives the multiple positioning posts 62 to move downward, so that the multiple connecting pieces 1 52 and the multiple connecting pieces 2 53 are all plugged and installed on the multiple connecting grooves 54, so that the control shaft 41 is connected with the rotating shaft 1 27 and the rotating shaft 2 28 at the same time, and the bottom of the multiple positioning posts 62 is flush with the upper surface of the mounting plate 1 25, that is, the rotating shaft 1 27 and the rotating shaft 2 28 are both in an unlocked state. At this time, the control shaft 41 rotates to drive the rotating shaft 1 27, the bevel gear 1 42 and the bevel gear 2 43 to rotate around the axis of the rotating shaft 1 27, that is, at this time, only the rotating shaft 1 27 is driven to rotate and the rotating shaft 2 28 will not be driven to rotate, so that the lamp body 23 rotates around the axis of the rotating shaft 1 27.

[0053] The moving member 73 drives the positioning sleeve 61 and the connecting sleeve 51 to continue to move downward, so that the positioning column 62 is plugged and installed on the mounting plate 25 for positioning. At this time, the bevel gear 42 can be positioned so that the bevel gear 42 cannot rotate, and the multiple connecting pieces 53 are disengaged from the connecting grooves 54, while the multiple connecting pieces 52 continue to be plugged into the connecting grooves 54. At this time, the control shaft 41 drives the rotating shaft 27 to rotate, and the rotation of the rotating shaft 27 drives the mounting seat 22, the rotating shaft 28 and the bevel gear 43 to rotate around the axis of the rotating shaft 27. Since the bevel gear 42 is positioned and cannot rotate, the bevel gear 43 and the rotating shaft 28 rotate under the action of the bevel gear 42, so that the lamp body 23 rotates around the axes of the rotating shaft 27 and the rotating shaft 28 at the same time.

[0054] After the rotation is completed, the moving part 73 drives the positioning sleeve 61 and the connecting sleeve 51 to continue to move downward, so that the positioning sleeve 61 and the sliding sleeve 44 are respectively against the mounting plate 1 25 and the mounting plate 2 26 for positioning, and at the same time, multiple positioning blocks 63 are plugged and installed on the connecting groove 54 for positioning, so that the rotating shaft 1 27 and the rotating shaft 2 28 cannot rotate, so that the illumination angle of the lamp body 23 can be adjusted according to needs, which improves the convenience and effect of adjusting the illumination angle of the lamp body 23, improves the adjustment efficiency and effect, and improves the display effect of the exhibits.

[0055] Reference Figure 2 and Figure 4 A rotating column 14 is rotatably mounted on the mounting seat 22 and located above the lamp body 23. The axes of the rotating column 14 and the second rotating shaft 28 are parallel. A lamp tube 29 is fixedly mounted on the rotating column 14. The lamp body 23 and the lamp tube 29 both irradiate in the same direction and cooperate with each other to illuminate the exhibits. The rotating column 14 is connected to the second rotating shaft 28 through a linkage mechanism 8. The linkage mechanism 8 realizes the rotating column 14 and the second rotating shaft 28 to rotate in the same direction or in the opposite direction, so that the angle between the lamp tube 29 and the lamp body 23 is appropriate, thereby improving the irradiation effect on the exhibits and improving the display effect of the exhibits.

[0056] A protective box 13 is fixedly installed on the mounting seat 22, so that the rotating column 14 and the end of the rotating shaft 28 away from the bevel gear 2 43 are both located in the protective box 13; the linkage mechanism 8 includes a first gear 81, a second gear 82, a third gear 83, and an adjusting component 9. The first gear 81 and the second gear 82 are both keyed to the rotating shaft 28, and the number of teeth of the first gear 81 is greater than that of the second gear 82. The third gear 83 is rotatably installed on the mounting seat 22 and meshes with the second gear 82; the adjusting component 9 is arranged on the rotating column 14, and the adjusting component 9 connects the rotating column 14 to the first gear 81 or the third gear 83 and makes the rotating column 14 and the rotating shaft 28 rotate in opposite or the same direction.

[0057] The adjusting assembly 9 includes an adjusting gear 91, an adjusting member 92 and an adjusting buckle 93. The adjusting gear 91 is slidably mounted on the rotating column 14, and the adjusting gear 91 rotates to drive the rotating column 14 to rotate; the adjusting member 92 is a cylinder or an electric push rod, and the adjusting member 92 is fixedly mounted on the outer wall of the protective box 13 and the piston rod passes through the protective box 13 and extends into the protective box 13; the adjusting buckle 93 is fixedly mounted on the piston rod of the adjusting member 92 and buckled on the adjusting gear 91, so that the adjusting gear 91 is rotationally connected with the adjusting buckle 93.

[0058] The adjusting member 92 starts to drive the adjusting gear 91 to engage with the first gear 81, and the rotating shaft 28 drives the adjusting gear 91, the first gear 81 and the lamp tube 29 to rotate, so that the lamp body 23 and the lamp tube 29 rotate at the same time and in opposite directions. Alternatively, the adjusting member 92 drives the adjusting gear 91 to engage with the third gear 83, and the rotating shaft 28 drives the lamp body 23 and the lamp tube 29 to rotate at the same time and in the same direction.

[0059] The working principle of the embodiment of the present application is as follows: The moving member 73 starts driving the positioning sleeve 61 and the connecting sleeve 51 to move simultaneously, and then the driving member 24 starts driving the rotating shaft 1 27 and the rotating shaft 2 28 to rotate simultaneously, driving the lamp body 23 to rotate in two mutually perpendicular directions, thereby roughly adjusting the illumination angle of the lamp body 23, and then controlling the driving member 24 to drive the rotating shaft 1 27 or the rotating shaft 28 to rotate as needed, so as to achieve fine adjustment of the angle of the lamp body 23 and the lamp tube 29. At the same time, the motor can also drive the mounting plate 12 to rotate, so that multiple lighting mechanisms 2 rotate to adjust the illumination angle until the desired angle is reached, thereby improving the adjustment efficiency and effect, and improving the display effect of the exhibits.

[0060] The mounting base 22 rotates to drive the lamp tube 29 to rotate simultaneously, and the rotating shaft 28 drives the lamp body 23 to rotate through the adjusting gear 91 and the first gear 81 to drive the lamp tube 29 to rotate simultaneously and in opposite directions. When the lamp tube 29 needs to be adjusted in the same rotation direction as the lamp body 23, the adjusting member 92 drives the adjusting gear 91 to engage with the third gear 83, and the rotating shaft 28 rotates through the adjusting gear 91, the second gear 82 and the third gear 83 to make the lamp tube 29 and the lamp body 23 rotate simultaneously and in the same rotation direction, thereby further improving the efficiency and effect of adjusting the angle of the lamp tube 29, so that the lamp body 23 and the lamp tube 29 cooperate to better illuminate the exhibits, thereby improving the display effect of the exhibits.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
