Description

Technical Field

[0001] This utility model relates to the field of cultural and creative toy technology, specifically to an adjustable-focus rotating optical projection cultural and creative toy. Background Technology

[0002] Currently, most optical projection toys on the market suffer from fixed structures and limited functions.

[0003] Traditional products often employ an integrated design with no adjustable projection focus, making it difficult to flexibly change the clarity and size of the projected image according to the usage scenario, greatly limiting the fun and adaptability of the toy. Furthermore, the installation of the projector in most products is complex, and the replacement process is cumbersome, which not only reduces the user experience but also fails to meet consumers' demands for diverse projected content.

[0004] In terms of structural adjustment, traditional projection toys lack convenient adjustment mechanisms, making it difficult to achieve precise control over the projection angle and range, and thus failing to meet users' needs in different environments. These problems collectively result in significant shortcomings in the fun, practicality, and safety of existing optical projection toys, making it difficult to meet the market's demand for high-quality cultural and creative toys. Utility Model Content

[0005] Technical problems to be solved

[0006] In view of the above-mentioned shortcomings of the existing technology, this utility model provides an adjustable-focus rotating optical projection cultural and creative toy, which can effectively solve the problems of integrated design, inability to adjust the projection focal length and difficulty in achieving precise control of projection angle and range in the existing technology.

[0007] Technical solution

[0008] This utility model provides an adjustable-focus rotating optical projection creative toy, including an outer cover assembly and an adjustment assembly sleeved on the outside of the outer cover assembly. The outer cover assembly includes an outer cover, an inner tube disposed inside the outer cover, and a light bulb fixed to the tail end of the inner tube. The front end of the inner tube is fixedly sleeved with the outer tube. The top ends of the outer cover, inner tube, and outer tube are provided with docking grooves, and a projection sheet is inserted into the docking grooves. The adjustment assembly includes an outer ring, a connecting ring, and a tail tube. The outer ring and the connecting ring, as well as the connecting ring and the outer tube, are all fixedly connected by a threaded structure. The connecting ring and the tail tube are hooked together. A lens is fixedly fixed in the middle of the tail tube and the middle of the outer ring. The tail end of the outer cover is fixedly connected to a base structure. The base structure includes a base platform and a connecting tube disposed on one side of the base platform. The two are fixedly connected by locking bolts.

[0009] Furthermore, the inner side of the inner tube is fixedly connected to the connecting plate by bolts, and the bulb is fixed on the connecting plate, and the tail end of the bulb is electrically connected to the power supply through the control component.

[0010] Furthermore, a slot is provided on the inner wall of the outer tube at a designated position, and a positioning ring is fixed on the outer side of the inner tube. The positioning ring is engaged in the slot to achieve a fixed connection between the inner side of the outer tube and the inner tube.

[0011] Furthermore, the base has a convex structure, and its top outer side is engaged and fixed with the inner side wall of the tail end of the outer cover. Both the base and the outer cover have threaded holes in their middle parts. The connecting pipe contacts the tail end of the outer pipe. Both the connecting pipe and the base have heat dissipation grooves in their middle parts.

[0012] Furthermore, in the two sets of threaded structures between the outer ring and the connecting ring, and between the connecting ring and the outer tube, the pitch of the threaded structure in the former is half that of the latter.

[0013] Furthermore, the tail end of the connecting ring is provided with an inward hooking ring, and the front end of the tail tube is provided with an embedded ring, with the hooking ring and the embedded ring being elastically engaged.

[0014] Beneficial effects

[0015] This utility model, through its outer casing assembly and base structure, allows for easy connection and fixation between the connecting tube and the base structure via locking bolts during operation. The base and the inner side of the outer casing remain engaged and fixed, facilitating power supply replacement and bulb maintenance, thus extending the lifespan of the device. The heat dissipation grooves quickly dissipate the heat generated by the bulb. The bulb and power supply structure are connected and fixed to the inner tube via a connecting plate. Users can fix and position the inner tube using the external positioning ring and the slot in the outer tube. Therefore, the projection panel can be positioned within the mating groove of the three components (outer casing, outer tube, and inner tube), allowing the bulb to directly illuminate the projection sheet and form an image through its multiple lens structures.

[0016] In this device, the adjustment component structure is first fixed by engaging with the outer tube via a connecting ring during connection. The connecting ring and the tail tube structure are hooked together, and the connecting ring and the outer ring are also fixed by engaging, achieving a unified assembly. Therefore, when the user adjusts the focus, the user can rotate the outer ring structure, causing the outer ring to move on the connecting ring. Since the pitch at this point is half that of the inner side, after the outer ring is unscrewed, the inner connecting ring structure is exposed. By rotating the connecting ring structure again, and because the pitches of the two are different, adjustments of different precision can be achieved, adjusting the distance between the lenses inside, thus realizing the active focusing function.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: A focusable rotating optical projection creative toy, see attached document. Figure 1 - Appendix Figure 5The system includes an outer casing assembly 1 and an adjustment assembly 4 fitted around the outer casing assembly 1. The outer casing assembly 1 includes an outer casing 11, an inner tube 12 disposed within the outer casing 11, and a bulb 13 fixed to the tail end of the inner tube 12. The front end of the inner tube 12 is fixedly fitted with the outer tube 15. The top ends of the outer casing 11, the inner tube 12, and the outer tube 15 are provided with mating grooves 16, and a projection sheet 3 is inserted into the mating grooves 16. The adjustment assembly 4 includes an outer ring 41, a connecting ring 43, and a tail tube 45. The outer ring 41 and the connecting ring 43, and the connecting ring 43 and the outer tube 15 are all fixedly connected by a threaded structure 44. The tail tubes 45 are hooked together, and lenses 42 are fixed to the middle of the tail tubes 45 and the middle of the outer ring 41. The tail of the outer cover 11 is fixedly connected to the base structure 2. The base structure 2 includes a base platform 21 and a connecting tube 22 set on one side of the base platform 21. The two are fixedly connected by locking bolts 23. The connecting ring 43 and the tail tube 45 are elastically connected by hooking ring and inner ring, which facilitates quick assembly and disassembly of components. The design of the threaded structure 44 makes the adjustment operation between the components simple and convenient. Users can adjust parameters such as focal length without complicated tools, which improves the ease of operation and user experience.

[0027] The inner tube 12 is secured to the outer tube 15 via a positioning ring 122 and a slot 151, ensuring the stability of the connection between the inner and outer tubes. The base 21 is engaged and secured to the inner wall of the tail end of the outer cover 11, and is connected to the connecting pipe 22 via a locking bolt 23, making the connection between the base structure 2 and the outer cover assembly 1 more secure. This multi-fixing structure effectively prevents shaking or tipping during use, improving the reliability of the product.

[0028] The inner tube 12 is fixedly connected to the connecting plate 121 by bolts, and the bulb 13 is fixed to the connecting plate 121. The tail end of the bulb 13 is electrically connected to the power supply 14 through a control component. A slot 151 is provided on the inner wall of the outer tube 15 at a designated position. A positioning ring 122 is fixed on the outer side of the inner tube 12. The positioning ring 122 is engaged in the slot 151, thus fixing the inner side of the outer tube 15 to the inner tube 12. The design of the mating groove 16 at the top of the outer cover 11, inner tube 12, and outer tube 15 makes the insertion and replacement of the projection sheet 3 simple and quick. Users can easily replace projection sheets with different patterns to achieve diverse projection content display, meet the needs of different theme projections, and enhance the interactivity and novelty of the toy.

[0029] The base 21 has a convex structure, and its outer top edge is engaged and fixed to the inner side wall of the tail end of the outer cover 11. Both the base 21 and the outer cover 11 have threaded holes in their middle sections. The connecting pipe 22 contacts the tail end of the outer tube 15. Both the connecting pipe 22 and the base 21 have heat dissipation grooves in their middle sections. Through the outer cover assembly 1 and the base structure 2, in actual operation, the connecting pipe 22 in the base and the base 21 are connected and fixed by locking bolts 23. The base 21 is engaged and fixed to the inner side of the outer cover 11. This engagement method facilitates user access to the power supply 14. Replacement of bulb 13 extends its service life. The heat dissipation groove can quickly dissipate the heat generated by bulb 13. Bulb 13 and power supply 14 are connected and fixed to inner tube 12 via connecting plate 121. The user can fix and position the inner tube 12 by using the external positioning ring 122 and the slot 151 in outer tube 15. Therefore, the projection board can be installed in the docking groove 16 of the three (outer cover 11, outer tube 15 and inner tube 12). Bulb 13 can directly illuminate the projection sheet 3 and form an image through the multiple lens 42 structure.

[0030] The toy achieves focus adjustment through a threaded structure 44 between the outer ring 41, connecting ring 43, and outer tube 15. The pitch of the threaded structure 44 between the outer ring 41 and connecting ring 43 is half that between the connecting ring 43 and outer tube 15. This design allows for more precise and delicate focus adjustment. Users can flexibly change the size and clarity of the projected image as needed, adapting to different usage scenarios and greatly enhancing the toy's fun and playability.

[0031] In the two sets of threaded structures 44 between the outer ring 41 and the connecting ring 43, and between the connecting ring 43 and the outer tube 15, the pitch of the former threaded structure 44 is half that of the latter; the tail end of the connecting ring 43 is provided with an inward hooking ring, and the front end of the tail tube 45 is provided with an embedded ring, with the hooking ring and the embedded ring elastically engaged; the adjusting component 4 structure, firstly, during connection, can be fixed by engaging the connecting ring 43 with the outer tube 15, and the connecting ring 43 and the tail tube 45 structure are hooked together, with the connecting ring 43 and the outer ring 41 being connected by hooking. Similarly, the fixed connection is achieved through meshing, thus achieving a unified combination. Therefore, when the user adjusts the focus, the user can rotate the outer ring 41 structure to move the outer ring 41 on the connecting ring 43. Since the pitch at this point is half that of the inner side, after the outer ring 41 is unscrewed, the inner connecting ring 43 structure is exposed. By rotating the connecting ring 43 structure, different levels of precision can be achieved due to the different pitches of the two structures. The distance between the lenses 42 inside the two structures can be adjusted to achieve the function of active focusing.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
