Technical Field
[0001] The utility model relates to the field of planetarium toys, in particular to an assembled planetarium toy. Background Art
[0002] A planet is a non-luminous celestial body that orbits a star, often in the same direction as the star's rotation. In the solar system, the eight planets orbiting the sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Planetarium toys are a great way to teach this concept to children.
[0003] However, most existing planetariums are directly produced as finished planetariums. Children receive a display toy that has been assembled and the planets are adjusted in position by a motor. As a result, the planetarium toy is only for viewing purposes and is difficult to promote children's hands-on practical ability and thinking ability, stimulate children's interest in exploration, and the production cost is relatively high.
[0004] The purpose of this utility model is to design an assembled planetarium toy in response to the problems existing in the above-mentioned prior art. Utility Model Content
[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides an assembled planetarium toy, which can effectively solve the problems existing in the above-mentioned prior art.
[0006] The technical solution of the utility model is:
[0007] An assembled planetarium toy, comprising:
[0008] base;
[0009] A support member is vertically detachably mounted on the base and is movable in an upward and downward positioning manner.

[0011] Furthermore, each of the circumferential limiting structures includes a plurality of limiting ribs with circumferentially spaced protrusions provided on the outer wall of the support member and forming a plurality of limiting grooves therebetween. A connecting hole is vertically penetrated through the connecting end, and the inner side of the connecting hole is divided into the limiting layer and the rotating layer in upper and lower layers. The circumferentially spaced protrusions on the inner wall of each limiting layer are provided with at least one positioning rib corresponding to the plurality of limiting grooves, and the inner diameter of the rotating layer is adapted to the outer diameter of the support member for rotation.
[0012] Furthermore, the number of the positioning ridges is smaller than the number of the limiting grooves, and the bottoms of several of the brackets are recessed to form de-weighting grooves, and the bottoms of the de-weighting grooves extend downward in a circular shape to form support tubes whose lower ends protrude from the notches of the de-weighting grooves, and the inner side of the support tubes penetrates to form the connecting holes, and the top of the brackets is recessed to provide an air-permeable groove with one end connected to the connecting hole; several of the connecting ends are stacked layer by layer from top to bottom through several of the supporting tubes, and several of the connecting holes are air-permeable through several of the limiting grooves, air-permeable grooves, and de-weighting grooves.
[0013] Furthermore, several of the support ends are arranged to extend outward in an arc shape laterally and upward, the widths of several of the connection ends gradually increase from top to bottom, and counterweights are fixedly provided on one side of several of the deweighting grooves away from the support ends.
[0014] Furthermore, the middle part of the base is recessed to provide a polygonal columnar movable groove, the lower outer wall of the support member protrudes outward and is provided with a polygonal columnar anti-rotation part, the anti-rotation part is inserted into the movable groove, and the middle part of the bottom of the anti-rotation part is recessed to form an upper top groove, and a spring is provided between the upper top groove and the movable groove, and the notch of the movable groove is detachable and provided with a limit cover located above the anti-rotation part and sleeved on the outside of the support member; when the spring pushes the anti-rotation part up against the bottom of the limit cover, several of the circumferential limit structures correspond to several of the restricted layers, and when the support member is pressed down to the anti-rotation part to compress the spring and abut against the bottom of the movable groove, several of the circumferential limit structures correspond to several of the rotating layers.
[0015] Furthermore, the outer circumference of the base is extended outward and the bottom is concave, and the bottom of the base is fixed with reinforcing ribs at circumferential intervals, one end of which is connected to the outer wall of the movable groove and the other end extends radially outward, and the outer ends of several of the reinforcing ribs are fixed with supporting feet protruding downward from the bottom of the base.

[0018] Therefore, the present invention provides the following effects and / or advantages:
[0019] 1. By disassembling the planetarium toy into an assembleable base, support members, several brackets, several planetary models, and several star models, the planetarium toy not only serves as a decorative ornament but also promotes children's hands-on practical skills and thinking abilities, stimulating their interest in exploration. Furthermore, by providing vertically movable support members and adding circumferential limiting structures, rotating layers and restricted layers are layered within the connecting end of the brackets. This allows the brackets to be rotationally locked relative to the support member when the support member moves to the restricted layers corresponding to the circumferential limiting structures, and to be rotationally unlocked relative to the support member when the support member moves to the rotating layers corresponding to the circumferential limiting structures. Thus, the brackets can be rotationally locked or unlocked by the vertical movement of the support member, allowing children to manually rotate the planetary models to the corresponding positions in the unlocked state and then lock them. This further promotes and stimulates children's hands-on practical skills and thinking abilities, and eliminates the need for a drive device to drive the planetary models. This reduces the production cost of the planetarium toy and increases its applicability to a wider range of people.
[0020] 2. After the support member moves downward to the corresponding circumferential limit structures corresponding to the rotational layers, the corresponding brackets are rotated. The support member is then moved upward so that the positioning ridges are inserted into the limit grooves to lock the brackets relative to the support member. This simple structure allows the brackets to be locked or unlocked relative to the support member, making locking and unlocking easier for younger children and expanding the age range of the planetarium toy.
[0021] 3. Under the premise of realizing the turnover locking of the bracket, the number of positioning ridges is reduced, and the ventilation between several connecting holes and the outside world is realized by adding ventilation grooves and deweighting grooves, so as to avoid the negative pressure attraction between the connecting ends of several brackets after overlapping, resulting in the rotation of the adjacent brackets when one of the brackets is rotated, causing the bracket positions to be disordered. At the same time, through the setting of the driving groove, the bracket can maintain the support strength of the planet model while reducing its own weight, so as to avoid the support end from bending downward and being damaged after long-term backward pressure, thereby extending the service life of the planetarium toy.
[0022] 4. The weight of the brackets at both ends relative to the support is balanced by the counterweights, so that no matter what angle the brackets rotate to, the force on the support is relatively balanced, avoiding the possibility of the support being skewed due to excessive force on one side, further extending the service life of the planetarium toy, and improving the overall placement stability of the planetarium toy.
[0023] It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the following embodiments and accompanying drawings:
[0034] refer to Figure 1-9 , an assembled planetarium toy, comprising:
[0035] Base 1;
[0036] A support member 2 is vertically detachably mounted on the base 1 and is movable in a vertical direction. A plurality of circumferential limiting structures 21 are provided on the outer side of the support member 2 from top to bottom. A star model 3 is detachably mounted on the upper end of the support member 2.
[0037] Several brackets 4, one end of which is a connecting end 41 that is sleeved on the outside of the support member 2 and stacked layer by layer from top to bottom, and the other end is a supporting end 42 that extends away from the support member 2, and several of the supporting ends 42 are respectively detachably provided with planetary models 5, and each of the connecting ends 41 is layered with a limiting layer 431 for circumferential limiting with the circumferential limiting structure 21 and a rotating layer 432 for circumferential rotation relative to the circumferential limiting structure 21; when the support member 2 moves to several of the circumferential limiting structures 21 corresponding to several of the limiting layers 431, several of the brackets 4 are circumferentially locked relative to the support member 2, and when the support member 2 moves to several of the circumferential limiting structures 21 corresponding to several of the rotating layers 432, several of the brackets 4 are circumferentially unlocked relative to the support member 2.
[0038] The above-described structure, by disassembling the planetarium toy into an assembleable base 1, a support member 2, a plurality of brackets 4, a plurality of planetary models 5, and a star model 3, makes the planetarium toy not only ornamental but also promotes children's hands-on practical skills and thinking abilities, stimulating their interest in exploration. Furthermore, by providing vertical positioning and movement of the support member 2 and adding a circumferential limiting structure 21, a rotating layer 432 and a restricted layer 431 are layered within the connecting end of the bracket 4. Thus, the vertical movement of the support member 2 enables the rotational locking or rotational unlocking of the plurality of brackets 4. This allows children to manually rotate the plurality of planetary models 5 to the corresponding position in the rotationally unlocked state and then lock them. This further promotes and stimulates children's hands-on practical skills and thinking abilities. Furthermore, by eliminating the need for a drive device to drive the planetary models 5 in rotation, the production cost of the planetarium toy is reduced, and the planetarium toy is suitable for a wider range of people.
[0039] To reduce production costs, each circumferential limiting structure 21 includes a plurality of limiting ribs 211 protruding circumferentially at intervals from the outer wall of the support member 2 and forming a plurality of limiting grooves 212 therebetween. A connecting hole 43 is vertically penetrated through the connecting end 41. The inner side of the connecting hole 43 is divided into a limiting layer 431 and a rotating layer 432. Each limiting layer 431 has at least one positioning rib 433 protruding circumferentially at intervals from the inner wall thereof, corresponding to the plurality of limiting grooves 212. The inner diameter of the rotating layer 432 is adapted to rotate with the outer diameter of the support member 2. Specifically, in this embodiment, the number of positioning ribs 433 is set to two and they are symmetrically arranged. After the support member 2 moves downward to the plurality of circumferential limiting structures 21 corresponding to the plurality of rotating layers 432, the corresponding bracket 4 is rotated. The support member 2 is then moved upward so that the positioning rib 433 is inserted into the limiting groove 212 for limiting the position, thereby locking the bracket 4 relative to the support member 2. Thus, the locking or unlocking of the plurality of brackets 4 relative to the support member 2 is achieved through a simple structure, which improves the convenience of locking or unlocking the brackets 4, facilitates operation by younger children, and expands the applicable age range of the planetarium toy.
[0040] In order to avoid the negative pressure attraction between the connection ends 41 of several brackets 4 after being stacked, which leads to the rotation of the adjacent brackets 4 when one of the brackets 4 is rotated, causing the position of the brackets 4 to be disordered, the number of the positioning ridges 433 is less than the number of the limiting grooves 212, and the bottom of several brackets 4 is recessed to form a de-weighting groove 44, and the bottom of the de-weighting groove 44 extends downward in an annular manner to form a support tube 441 whose lower end protrudes from the notch of the de-weighting groove 44, and the inner side of the support tube 441 passes through to form the connecting hole 43, and the top of the bracket 4 is recessed to provide a ventilation groove 442 with one end connected to the connecting hole 43; several of the connection ends 41 are stacked layer by layer from top to bottom through several of the supporting tubes 441, and several of the connecting holes 43 are ventilated through several of the limiting grooves 212, ventilation grooves 442, and de-weighting grooves 44. Thus, under the premise of achieving turnover locking of the bracket 4, the number of positioning ribs 433 is reduced, and by adding ventilation grooves 442 and deweighting grooves 44, ventilation between the several connecting holes 43 and the outside world is achieved, so as to avoid negative pressure attraction between the connecting ends 41 of the several brackets 4 after being stacked, resulting in the rotation of one of the brackets 4 and the rotation of the adjacent brackets 4, causing the position of the brackets 4 to be disordered. At the same time, through the setting of the driving groove, the bracket 4 can reduce its own weight while maintaining the supporting strength of the planet model 5, so as to avoid the support end 42 from bending downward and being damaged after long-term backward pressure, thereby extending the service life of the planetarium toy.
[0041] To improve the stability of bracket 4 after the planetary model 5 is mounted, several of the support ends 42 extend laterally outward in an arc-shaped configuration. The width of the several connecting ends 41 gradually increases from top to bottom. Counterweights 443 are fixed to the side of the several weight-removing grooves 44 away from the support ends 42. Specifically, the weights of the several counterweights 443 are adapted to the corresponding planetary model 5. Counterweights 443 thus balance the weight of bracket 4 relative to support member 2, ensuring that the force applied to support member 2 is relatively balanced regardless of the angle to which the brackets 4 rotate. This prevents the support member 2 from tilting due to excessive force on one side, further extending the life of the planetarium toy and improving its overall placement stability.
[0042] In order to stably position the support member 2 for upward and downward movement, the base 1 is recessed with a polygonal cylindrical moving groove 11 in the middle part, and the lower outer wall of the support member 2 protrudes outward and is provided with a polygonal cylindrical stop portion 22, and the stop portion 22 is inserted into the moving groove 11, and the middle part of the bottom of the stop portion 22 is recessed to form an upper top groove, and a spring 23 is provided between the upper top groove and the moving groove 11, and the notch of the moving groove 11 is detachably provided with a limit cover 12 located above the stop portion 22 and sleeved on the outside of the support member 2; when the spring 23 pushes the stop portion 22 up against the bottom of the limit cover 12, several of the circumferential limiting structures 21 correspond to several of the restricted layers 431, and when the support member 2 is pressed down to the stop portion 22 to compress the spring 23 and abut against the bottom of the moving groove 11, several of the circumferential limiting structures 21 correspond to several of the rotating layers 432. Thus, the support member 2 can be stably positioned when moving up and down by adding the anti-rotation part 22, the movable groove 11, the limit cover 12 and the spring 23. At the same time, the anti-rotation part 22 and the movable groove 11 are set to be polygonal columns to prevent the support member 2 from rotating relative to the base 1.
[0043] To enhance the stability of the planetarium toy, the base 1 has an outwardly extending outer circumference and a concave bottom. Reinforcing ribs 13 are fixedly mounted at intervals along the circumference of the base 1, one end connected to the outer wall of the movable groove 11 and the other end extending radially outward. Several of the reinforcing ribs 13 have support feet 14 fixedly mounted at their outer ends, protruding downward from the base 1. When the planetarium toy is placed on a flat surface such as a table, the support feet 14 elevate the base 1 to create a gap between the base 1 and the table, expanding the base 1's surface area. This improves placement stability while reducing the contact area between the base 1 and the table, making it easier to clean. The addition of the reinforcing ribs 13 also enhances the overall structural strength of the movable groove 11 and base 1.
[0044] To facilitate installation of the planetary models 5, several of the support ends 42 are recessed with polygonal column 6 grooves 421, into which polygonal columns 6 are adapted to be inserted. Several of the bottoms of the planetary models 5 are recessed with cylindrical mounting grooves, through which the planetary models 5 are rotatably inserted into the upper ends of the polygonal columns 6. Thus, through the insertion between the polygonal columns 6 and the cylindrical mounting grooves, a gap is created between the two, preventing the planetary models 5 from being too tightly connected to the polygonal columns 6, which would make assembly and disassembly difficult. This allows for easy adjustment of the planetary models 5 to different brackets 4, and after installation, the display angle of the planetary models 5 can be adjusted by circumferential rotation at any time.
[0045] Specifically, in this embodiment, the star model 3 is a solar model, the planet models 5 are eight in number and are respectively a Mercury model, a Venus model, an Earth model, a Mars model, a Jupiter model, a Saturn model, a Uranus model, and a Neptune model, and the supports 4 are eight in number, with the eight support ends 42 being sequentially arranged from the inside out. In other embodiments, the star model 3 and planet models 5 may also be designed to mimic stars and planets in other galaxies.
[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
