Description

Technical Field

[0001] The present utility model relates to the technical field of light boxes, in particular to a special-shaped four-sided rotating light box. Background Art

[0002] Lights, which are lighting articles, generally refer to tools that can provide illumination. In ancient times, humans used torches for lighting, and later candles and oil lamps emerged. In ancient times, "candle" referred to a torch made of flammable materials; a lit torch held by hand was called a candle; piles of fine grass and branches placed on the ground for ignition were called liao, the liao placed outside the door was called a large candle, and the one placed inside the door was called a courtyard liao.

[0003] After retrieval, the existing patent with the publication number CN212298698U proposes a special-shaped four-sided rotating light box, which belongs to the technical field of light box equipment. The light box comprises a light box mechanism, the light box mechanism is composed of a first special-shaped plate, a support rod, a second special-shaped plate and a light-transmitting plate, a bearing is inlaid and connected on the top surface of the first special-shaped plate, a stand column is inserted into the inner cavity of the bearing, a U-shaped frame is installed in the inner cavity of the light box mechanism, LED lamps are installed on both outer side walls of the U-shaped frame, a motor is installed on one side of the top surface of the U-shaped frame, a driving gear is arranged on one side of the top of the motor, and a driven gear is meshed and connected to one side of the driving gear. Through the light box mechanism, the light box can have a special-shaped appearance, thereby making the structure of the light box more fashionable. Through the LED lamps, the light box mechanism can be illuminated, so as to achieve the lighting effect. Since the light box mechanism is connected with the stand column through the bearing, the light box mechanism can be driven to rotate by the motor via the gears, which enhances the functionality of the light box.

[0004] In the above-mentioned prior art, due to the combination of the special-shaped appearance and the rotation function, a visual blind spot exists when observing from one side. This visual blind spot makes it impossible for the observer to accurately judge the overall motion trajectory of the light box during rotation, and further cannot determine how far away from the light box is required to avoid being hit, which lays a hidden danger for accidental touch, and particularly easily causes the risk of accidental touch for children with low judgment ability and naturally active nature. Contents of the Utility Model

[0005] The purpose of this section is to outline some implementations of the utility model and briefly introduce some preferred implementations. Simplifications or omissions may be made in this section as well as in the abstract of the specification and the title of the utility model to avoid obscuring the purpose of this section, the abstract of the specification and the title of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] In view of the above and / or the existing problems in the special-shaped four-sided rotating light box, the utility model is proposed.

[0007] In order to solve the above technical problems, according to one aspect of the utility model, the following technical solutions are provided. A uniquely shaped four-sided rotating light box includes a base, a support column at the top of the base, a light fixture on the support column, a pair of frames symmetrically arranged on the base via a connecting mechanism, and uniformly distributed cover plates symmetrically arranged on the outer wall of the frames.

[0008] As a preferred embodiment of the irregular four-sided rotating light box described in this utility model, the cover plate is set to an irregular shape.

[0009] As a preferred embodiment of the irregular four-sided rotating light box described in this utility model, connecting rods are symmetrically arranged between the frames.

[0010] As a preferred embodiment of the irregular four-sided rotating light box described in this utility model, the connecting mechanism includes a connecting plate disposed between a pair of frames via a fixing rod, a placement frame disposed on the outer wall of the connecting plate, a support frame rotatably mounted under the bottom surface of the placement frame, and a housing rotatably mounted under the bottom surface of the support frame, with the housing disposed on the top surface of the light fixture.

[0011] As a preferred embodiment of the irregular four-sided rotating light box of this utility model, a motor is provided inside the housing, a second insert is provided on the output end of the motor, a rotating block is provided on the outer wall of the second insert, a first protrusion is provided on the outer wall of the rotating block, a first insert is provided inside the placement frame, a connecting block is provided at the bottom of the first insert, a rotating frame is provided on the inner wall of the connecting block, a second protrusion is provided inside the rotating frame, and the second protrusion abuts against the rotating frame.

[0012] As a preferred embodiment of the irregular four-sided rotating light box described in this utility model, the second protrusion is configured as an elastic structure, and the first protrusion is configured as a rigid structure.

[0013] As a preferred embodiment of the irregular four-sided rotating light box described in this utility model, a plurality of magnetic blocks are provided on the outer wall of the first protrusion, and the magnetic blocks are magnetically engaged with the rotating frame.

[0014] As a preferred embodiment of the irregular four-sided rotating light box described in this utility model, the placement frame is provided with a plurality of first partitions and second partitions, and the second partitions are inserted into the first partitions to form a plurality of placement cavities.

[0015] As a preferred embodiment of the irregular four-sided rotating light box described in this utility model, a number of counterweights are placed inside the placement cavity.

[0016] Compared with the prior art, the beneficial effects of this utility model are: When the cover plate encounters an obstacle while rotating, the obstacle exerts a reverse resistance on the cover plate. The resistance is transmitted to the rotating frame through the frame, fixed rod, connecting plate, placement frame, first insert rod, and connecting block, preventing the rotating frame from continuing to rotate with the rotating block. At this time, the motor still drives the rotating block to rotate. The magnetic block of the first protrusion squeezes the elastic second protrusion, and the second protrusion deforms under force, allowing the first protrusion to pass over the second protrusion and continue to rotate. That is, the rotating block spins freely. Since the rotating frame no longer rotates with the rotating block, the cover plate also stops rotating, avoiding continuous force that could damage the obstacle. By placing counterweights inside the placement cavity of the placement frame, counterweights can be placed in the lightweight areas of the placement frame according to the weight distribution of the cover plate, thus balancing the overall weight of the placement frame and the frame, so that the force is evenly distributed in all directions when the light box rotates, reducing uneven wear.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Example 1 Please see Figures 1-6 This utility model provides a technical solution: an irregularly shaped four-sided rotating light box, including a base 1, a support column 2 fixedly installed on the top of the base 1, the support column 2 extending vertically upward to provide installation support for the light fixture 4 above, the light fixture 4 being fixedly installed at the top of the support column 2, the light fixture 4 being an LED light source assembly that can emit uniform light and serve as the lighting core of the light box, a pair of frames 6 symmetrically fixedly installed on the base 1 through a connecting mechanism 5, the frames 6 being rectangular or polygonal frames welded from metal rods, used to fix the cover plate 3, the outer walls of the frames 6 being symmetrically fixedly and evenly distributed cover plates 3, the cover plates 3 being irregularly shaped and made of light-transmitting material, the light emitted by the light fixture 4 can pass through the cover plate 3, presenting a light and shadow effect matching the shape of the cover plate, realizing the display function, connecting rods 7 symmetrically fixedly installed between the frames 6, the connecting rods 7 horizontally connecting the two frames 6, enhancing the overall rigidity of the frame, and preventing the frame from deforming during rotation and causing the cover plate 3 to loosen.

[0023] The connecting mechanism 5 is the core for realizing the rotation of the light box and the protection against accidental touch. It includes a fixing rod 8, which is fixedly connected between a pair of frames 6. A connecting plate 15 is fixedly set in the middle of the fixing rod 8. A placement frame 9 is fixedly set on the outer wall of the connecting plate 15. The placement frame 9 is a hollow box. A support frame 18 is rotatably installed under the bottom surface of the placement frame 9 via a bearing. A housing 13 is rotatably installed under the bottom surface of the support frame 18 via a bearing. The housing 13 is fixedly set on the top surface of the lamp 4. The rotational installation of the support frame 18 allows the placement frame 9 to rotate flexibly relative to the housing 13. A motor 14 is fixedly set inside the housing 13. The motor 14 provides power for the rotation of the light box. The output end of the motor 14 extends vertically upward and is fixedly set with a second insertion rod 24. A sleeve is fixedly fitted on the outer wall of the second insertion rod 24. There is a rotating block 19, and a first protrusion 20 is fixedly and evenly distributed on the outer wall of the rotating block 19. The first protrusion 20 is a rigid structure. Several magnetic blocks 21 are fixedly and evenly distributed on the outer wall of the first protrusion 20. The magnetic blocks 21 are permanent magnets used to enhance the engagement stability during transmission. A first insert rod 17 is fixedly and evenly distributed inside the placement frame 9. A connecting block 12 is fixedly and evenly distributed on the bottom of the first insert rod 17. A rotating frame 22 is fixedly and evenly distributed on the inner wall of the connecting block 12. The rotating frame 22 is a ring structure and is fitted outside the rotating block 19. A second protrusion 23 is fixedly and evenly distributed on the inner wall of the rotating block 19. The second protrusion 23 is an elastic structure and corresponds to the first protrusion 20 of the rotating block 19. The magnetic blocks 21 and the rotating frame 22 are opposite magnetic poles and can attract each other.

[0024] In normal rotation, motor 14 starts, driving the second insert rod 24 and rotating block 19 to rotate synchronously. The first protrusion 20 of rotating block 19 rotates inside rotating frame 22. Magnetic block 21 is attracted to rotating frame 22, causing the first protrusion 20 to fit tightly against the second protrusion 23. Since there are no external obstacles at this time, the rotational resistance is small. The elastic second protrusion 23 can support the rigid first protrusion 20. The two are engaged as one. Rotating block 19 drives rotating frame 22 to rotate synchronously. Rotating frame 22 drives placement frame 9 to rotate through connecting block 12 and first insert rod 17. In turn, it drives frame 6 and cover plate 3 to rotate synchronously through connecting plate 15 and fixing rod 8, realizing normal display function.

[0025] When the cover plate 3 rotates and encounters an obstacle, such as a child's hand, the obstacle exerts a reverse resistance on the cover plate 3. This resistance is transmitted to the rotating frame 22 via the frame 6, fixing rod 8, connecting plate 15, placement frame 9, first insert rod 17, and connecting block 12, preventing the rotating frame 22 from continuing to rotate with the rotating block 19. At this time, the motor 14 still drives the rotating block 19 to rotate. The magnetic block 21 of the first protrusion 20 squeezes the elastic second protrusion 23, causing the second protrusion 23 to deform under force, allowing the first protrusion 20 to pass over the second protrusion 23 and continue to rotate. That is, the rotating block 19 spins freely. Since the rotating frame 22 no longer rotates with the rotating block 19, the cover plate 3 also stops rotating, avoiding continuous force that could damage the obstacle. When the obstacle is removed, the reverse resistance disappears, the magnetic block 21 re-attaches the rotating frame 22, the first protrusion 20 and the second protrusion 23 engage again, and the cover plate 3 resumes normal rotation.

[0026] Example 2 Please see Figures 1-6 The present invention provides a technical solution: a plurality of first partitions 10 and second partitions 11 are fixedly arranged inside the placement frame 9. The first partitions 10 are evenly distributed along the length direction of the placement frame 9, and the second partitions 11 are evenly distributed along the width direction of the placement frame 9. The second partitions 11 are perpendicularly inserted into the first partitions 10. The two intersect to form a plurality of placement cavities of the same size. The placement cavities are used to place counterweights 16. The counterweights 16 are high-density metal blocks, and counterweights of different weights can be selected according to requirements.

[0027] Because the cover plate 3 has an irregular shape, the weight of different areas varies. For example, the weight of the convex end of the arc-shaped cover plate is greater than that of the concave end. Long-term rotation will cause the wear of the unbalanced side of the transmission component to accelerate and shorten its service life. By placing a counterweight 16 in the placement cavity of the placement frame 9, the counterweight can be placed in the lightweight area of ​​the placement frame 9 according to the weight distribution of the cover plate 3, so as to balance the overall weight of the placement frame 9 and the frame 6, so that the force is evenly distributed in all directions when the light box rotates, and the wear of the unbalanced side is reduced.

[0028] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
