Description

Technical Field

[0001] This utility model relates to the field of building block assembly toys, specifically a magnetic adsorption and fixing building block toy. Background Technology

[0002] In recent years, building block toys have been widely used in various fields such as educational play, entertainment and collection, and the dissemination of traditional culture due to their high degree of freedom in assembly, diverse forms, and reusability. They have gradually become one of the important carriers of cultural and creative products.

[0003] However, most existing jigsaw puzzle building block products use traditional slotted splicing structures or lack clear structural constraints, relying solely on friction to maintain the assembled state. These structures have several limitations when dealing with multiple complex parts: First, during assembly, the large number of parts can easily lead to inaccurate positioning, affecting the overall structural stability; second, disassembly and removal after use are difficult, especially when there are many or closely spaced blocks, requiring users to manually move and remove them one by one, which is cumbersome and reduces their willingness to reuse them; third, the lack of effective fixing and protection devices makes them prone to loosening or falling off after assembly, making long-term preservation and display difficult. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a magnetic adsorption and fixation toy for building blocks, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic adsorption and fixing building block toy, including a base, a building block splicing frame disposed inside the base, a magnetic adsorption component for achieving magnetic adsorption and fixing, and a magnetic force adjustment mechanism for adjusting the magnetic adsorption strength to assist in disassembly. The building block assembly frame has an internal assembly groove that fits the shape of the building block board. The bottom of the building block board is inlaid with a magnetic piece. The number and shape of the assembly groove can be customized according to the preset assembly shape requirements, and each set of assembly grooves corresponds to a building block board with a magnetic piece. The magnetic assembly includes a magnet plate located inside the base and below the building block assembly frame, and multiple sets of first springs connected between the magnet plate and the building block assembly frame. In the initial state, the distance between the magnet plate and the magnetic sheet can generate a stable adsorption force, so that the building block board is fixed in the assembly groove. The magnetic force adjustment mechanism includes push plates symmetrically arranged on both sides of the base, a sliding plate connected to the push plates and slidable along the base, a second inclined block fixed to the inner side of the sliding plate, and a first inclined block fixed to both sides of the magnet plate and cooperating with the inclined surface of the second inclined block. Pushing the push plates can drive the sliding plate and the second inclined block to move. The magnet plate is lowered and the first spring is stretched through the transmission of the first inclined block, increasing the distance between the magnet plate and the magnetic sheet to weaken the adsorption force. The first spring is provided in multiple sets, which are fixed at the top center and four corners of the magnet plate to ensure the force balance during the lifting and lowering process of the magnet plate; The second inclined block has a guide rail that extends into the first inclined block, and the first inclined block has a guide groove that matches the guide rail, and the guide rail has a "T" shaped cross section. The magnetic adjustment mechanism also includes a fixed frame fixed to the inner wall of the base, a guide rod passing through the fixed frame, and a second spring sleeved on the outside of the guide rod; One end of the guide rod is fixed to the inside of the fixing plate, and the fixing plate is fixed to the top of the second inclined block. The two ends of the second spring abut against the fixing plate and the fixing frame respectively. In the non-disassembled state, the elastic force of the second spring can keep the second inclined block, the first inclined block and the magnet plate in a stable position. Both sides of the building block assembly frame are fixed with buckles, and both sides of the base have slots that match the buckles. It also includes a transparent protective cover for protecting the structure after assembly. The transparent protective cover is detachably connected to the base, and the inner contour of the transparent protective cover is adapted to the overall contour of the assembled block frame and block boards.

[0006] In summary, the present invention has the following main advantages: 1. This utility model utilizes a magnetic assembly that incorporates a built-in magnetic plate and a magnetic sheet embedded in the building block board. Combined with an assembly groove within the building block assembly frame that adapts to the shape of the building block board, it forms a dual constraint of physical positioning and magnetic fixation. The assembly groove provides a clear installation guide for the building block board, avoiding the problem of inaccurate positioning caused by multiple parts and angle deviations in traditional slot assembly. In the initial state, the distance between the magnetic plate and the magnetic sheet is precise, and the magnetic force stably attracts the building block board, preventing the parts from loosening or falling off due to splicing gaps or external force contact in traditional friction fixing methods. Even when assembling multiple layers or irregularly shaped structures, the overall shape remains stable. 2. This utility model, through the design of a push plate, a sliding plate, a first inclined block, a second inclined block, and a magnetic force adjustment mechanism for transmission, allows the magnetic plate to descend by manually pushing the push plate, increasing the distance between it and the magnetic sheet to weaken the adsorption force. Unlike traditional slotted building blocks, there is no need to disassemble the parts one by one. Simply push the push plates on both sides, and all the building blocks can be released from the magnetic constraint and poured out of the assembly groove as a whole. It is especially suitable for scenarios with a large number of building blocks and close arrangement, simplifying the disassembly steps from "disassembling one by one" to "one-click demagnetization + overall export", greatly saving disassembly time, reducing the user's operating burden, reducing the situation of "unwilling to disassemble again after assembly" due to tedious disassembly, improving the reuse rate of building blocks, and meeting the needs of educational toys for "multiple assembly and repeated creation".

Detailed Implementation

[0009] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0010] The embodiments of this utility model will be described below based on its overall structure.

[0011] Example 1 like Figures 1-4 As shown in the figure, this embodiment discloses a magnetic adsorption and fixing building block toy, which aims to solve the problems of inaccurate positioning, cumbersome disassembly, and difficulty in long-term storage of traditional building blocks through structural design. Its specific structure and working process are as follows: This magnetically attached building block toy includes a base 1, a building block assembly frame 4, a magnetic assembly, a magnetic adjustment mechanism, and a transparent protective cover 20. The connection relationships and functions of each component are as follows: The base 1 serves as the installation foundation for the overall structure. It has a hollow interior to accommodate the building block frame 4, magnetic components, and magnetic adjustment mechanism. The interior has slots 18 on both sides that mate with the building block frame 4.

[0012] The building block assembly frame 4 is installed inside the base 1 and is fixed by the buckles 17 on both sides and the slots 18 inside the base 1. Multiple sets of assembly grooves 5 are opened inside the frame. The shape of the assembly grooves 5 is adapted to the shape of the building block board 6 to be assembled, and is used to provide physical limit for the building block board 6.

[0013] The building block board 6 is the core component for assembly. It has a magnetic piece 7 embedded in the bottom, which can be fixed in the assembly groove 5 of the building block assembly frame 4 by the attraction between the magnetic piece 7 and the magnetic component.

[0014] The magnetic attraction assembly includes a magnet plate 2 and multiple sets of first springs 3; The magnet plate 2 is located inside the base 1 and below the building block assembly frame 4. It is used to generate an adsorption force with the magnetic sheet 7 at the bottom of the building block board 6. Multiple sets of first springs 3 are fixed at the top center and four corners of the magnet plate 2, and the other end is connected to the bottom of the building block assembly frame 4 to support the magnet plate 2 and ensure the force balance during its lifting and lowering process.

[0015] The magnetic adjustment mechanism includes a push plate 19, a sliding plate 9, a second inclined block 10, a first inclined block 8, a fixed frame 16, a guide rod 14, a second spring 15, and a fixed plate 13; Push plates 19 are symmetrically arranged on both sides of the base 1 and connected to the outer side of the sliding plate 9. A second inclined block 10 is fixed on the inner side of the sliding plate 9, and a guide rail 11 is fixed on the inner side of the second inclined block 10. A first inclined block 8 is fixed on both sides of the magnet plate 2 and has a guide groove 12 that cooperates with the guide rail 11. The guide rail 11 and the guide groove 12 are slidably connected to achieve the inclined surface cooperation between the first inclined block 8 and the second inclined block 10. The fixing frame 16 is fixed to the inner wall of the base 1. The guide rod 14 passes through the fixing frame 16 and is fixed at one end to the inner side of the fixing plate 13. The fixing plate 13 is fixed to the top of the second inclined block 10. The second spring 15 is sleeved on the outer side of the guide rod 14 and its two ends abut against the fixing plate 13 and the fixing frame 16 respectively, in order to maintain the stability of the magnetic adjustment mechanism in the non-working state.

[0016] The transparent protective cover 20 is detachably connected to the base 1. The inner wall contour is adapted to the overall contour of the assembled block frame 4 and block board 6, which is used to protect the structure after assembly.

[0017] The working principle of this utility model is as follows: In actual use, a building block splicing frame 4 is installed inside the base 1, and a splicing groove 5 is opened inside the building block splicing frame 4. The splicing groove 5 can be opened according to the actual shape of the building blocks, so that the building block board 6 with magnetic pieces 7 embedded at the bottom can be installed into the splicing groove 5. Furthermore, a magnetic plate 2 is also provided inside the base 1. Multiple sets of first springs 3 are fixed between the magnetic plate 2 and the building block assembly frame 4. The first springs 3 are in the initial state. The distance between the magnetic plate 2 and the magnetic sheet 7 is just enough to allow the magnetic force generated by the magnetic plate 2 to stably attract and fix the magnetic sheet 7 to each other, so that the building block board 6 is stably placed inside the assembly groove 5. When it is necessary to disassemble the assembled building block board 6, the user manually pushes the sliding plate 9 into the base 1 through the two sets of push plates 19, thereby causing the second inclined block 10 to slide into the base 1. Since the second inclined block 10 and the first inclined block 8 are connected by an inclined sliding surface, when the two sets of second inclined blocks 10 move relative to each other, the pushing force is applied to the magnet plate 2 through the first inclined block 8. At this time, the magnet plate 2 descends inside the base 1 under the action, and the multiple sets of first springs 3 are in a passively stretched state. In other words, at this time, the distance between the magnetic sheet 7 between the magnetic plate 2 and the building board 6 increases, making it difficult for the magnetic plate 2 and the magnetic sheet 7 to magnetically stabilize and fix the building board 6. Thus, multiple sets of building blocks 6 are contacted and limited inside the assembly groove 5, so that the assembled building blocks 6 can be directly poured out of the building block assembly frame 4; Furthermore, when the second inclined block 10 slides, the fixing plate 13 compresses the second spring 15, and the guide rod 14 slides along the fixing frame 16. When the push plate 19 is not pushed, the second spring 15 is in a compressed state, which keeps the second inclined block 10, the first inclined block 8 and the magnet plate 2 stable. In summary, relying on the magnetic adsorption structure of "base 1 with built-in magnetic plate 2 + building block board 6 with embedded magnetic sheet 7", combined with the assembly groove 5 in the building block splicing frame 4 that adapts to the shape of building block board 6, a dual constraint of "physical limitation + magnetic fixation" is formed. Specifically, the assembly groove 5 can be customized according to the actual shape of the building board 6, providing a clear installation guide for each building board 6. This avoids the problem of inaccurate positioning caused by too many parts and angle deviation in traditional slot splicing, and reduces the operational difficulty of assembling complex shapes. In the initial state, the distance between the magnetic plate 2 and the magnetic sheet 7 embedded in the building board 6 is precisely designed. The magnetic force can stably attract and fix the building board 6, avoiding the problem of loosening and falling off of parts caused by splicing gaps and external force contact in traditional friction fixing methods. Even when assembling multi-layer and irregular structures, the overall shape can remain stable. The magnetic adjustment mechanism is designed with "push plate 19, sliding plate 9, and inclined block transmission". By manually pushing the push plate 19, the magnetic plate 2 is driven down, increasing the distance between the magnetic plate 2 and the magnetic sheet 7, thus weakening the magnetic attraction force. Unlike traditional slotted building blocks, which require individual manipulation and disassembly of components, this method simply involves pushing the push plates 19 on both sides to release all the building blocks 6 from their magnetic constraints. The blocks are then released from their positions within the assembly grooves 5, allowing the entire block 6 to be poured out. This is particularly suitable for scenarios with a large number of closely spaced building blocks. The operation is simplified from "disassembling one by one" to "one-click demagnetization + overall export," saving significant disassembly time. The convenient disassembly process reduces the user's workload and minimizes the "unwillingness to disassemble after assembly" caused by tedious disassembly. This increases the reusability of building block toys and better meets the needs of educational toys for "multiple assembly and repeated creation."
