Description

TECHNICAL FIELD

[0001] The utility model relates to a jigsaw puzzle board technical field, specifically is a jigsaw puzzle board with magnetic frame. BACKGROUND

[0002] In the field of jigsaw puzzles, traditional felt jigsaw puzzle boards are widely used. However, such jigsaw puzzle boards have obvious defects. Many players will choose to use glue to fix the jigsaw puzzle pieces after completing the jigsaw puzzle in order to preserve the jigsaw puzzle work for a long time. However, this operation causes the glue to penetrate into the felt, making the jigsaw puzzle pieces and the felt tightly adhere to each other and difficult to separate. If the player wants to replace the felt to perform a new jigsaw puzzle activity, it is almost impossible to achieve, and the old jigsaw puzzle board can only be discarded as a whole, resulting in resource waste and cost increase.

[0003] With the increase of the use time, the surface of the felt will gradually decrease in friction due to frequent contact with the jigsaw puzzle pieces. This makes the jigsaw puzzle pieces more likely to slide and shift during the assembly process, greatly reducing the stability and operation experience of the jigsaw puzzle, especially for complex jigsaw puzzles with a large number of pieces, the problem is more prominent. In addition, the special fiber structure of the felt makes it easy to adsorb dust, hair and other debris. Even if a variety of cleaning tools and methods are used during daily cleaning, it is difficult to completely remove these debris, which not only affects the appearance of the jigsaw puzzle board, but also further interferes with the friction between the jigsaw puzzle pieces and the surface of the felt, reducing the use effect.

[0004] At present, most of the jigsaw puzzle boards on the market are designed in an integrated manner and cannot realize the convenient replacement of the felt. In view of these problems, it is urgent to develop a new structure of jigsaw puzzle board which can solve the problems of non-replaceable felt, decreased friction and difficult cleaning, thereby providing a more high-quality, durable and easy-to-maintain jigsaw puzzle tool for jigsaw puzzle enthusiasts.

[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] Please refer to Figures 1-5 In the embodiments of the present application, a puzzle board with a magnetic frame 30 comprises a puzzle board body 10 and a frame 30 detachably connected with the puzzle board body 10. The surface of the puzzle board body 10 is provided with a working layer 40 for assisting in puzzle. The frame 30 is used for pressing the working layer 40 to achieve its fixation.

[0039] In the technical solutions of the present application, the working layer 40 is arranged on the surface of the puzzle board body 10, which is a key part directly contacting with puzzle pieces and assisting in puzzle operation. From the material angle, the common working layer 40 material such as felt has unique surface characteristics. The fiber structure on the surface of the felt can provide a certain friction for the puzzle pieces, so that the pieces can be relatively stably stayed on the surface of the working layer 40 in the process of splicing and are not easy to slide randomly, which is crucial for the smooth progress of the puzzle. Furthermore, the working layer 40, the puzzle board body 10 and the frame 30 form an organic whole structure. The working layer 40 is placed on the surface of the puzzle board body 10, and the frame 30 surrounds the edge of the working layer 40 and presses and fixes it. This structure design ensures that the working layer 40 always maintains a stable position in the process of puzzle, and will not be displaced or wrinkled due to factors such as vibration and collision in the operation process, thereby providing a stable basis for puzzle operation.

[0040] By adopting the frame 30 detachably connected with the jigsaw board body 10, a flexible structure system is constructed, and the design allows the user to conveniently separate the frame 30 from the jigsaw board body 10 when needed, and then easily access and operate the work layer 40 on the surface of the jigsaw board body 10; the principle is to break the fixed mode of the traditional jigsaw board frame 30 and the work layer 40 integration by using the detachable connection mode, to create conditions for the replacement of the work layer 40; the function of the frame 30 is not only decoration or simple enclosure, but more importantly, it is used to compress the work layer 40; when the frame 30 is connected with the jigsaw board body 10, through a suitable pressure application mode (such as the weight of the frame 30 itself, the pressure generated by the connection structure, the force, etc.), the work layer 40 is ensured to be firmly attached to the surface of the jigsaw board body 10, preventing the work layer 40 from being displaced, wrinkled or affecting the jigsaw operation during use, and ensuring the stability of the work layer 40 during the jigsaw process.

[0041] In summary, the utility model can effectively:

[0042] Solve the problem of non-replaceable work layer 40: For the pain point that the traditional felt jigsaw board cannot replace the felt due to glue adhesion, the detachable frame 30 of the design enables the user to easily remove the frame 30 when the jigsaw and the felt are adhered or the felt is in other unusable conditions, remove the old work layer 40 and replace a new work layer 40, which effectively avoids the situation that the jigsaw board needs to be discarded as a whole due to damage or adhesion of the work layer 40, greatly saves resources and reduces the user's use cost;

[0043] Improve the problem of decreased friction: as the use time increases, the friction of the work layer 40 will gradually decrease; in the design, when the work layer 40 (such as felt) is affected by the decreased friction during the jigsaw operation, the user can replace a new work layer 40 by detaching the frame 30; the new work layer 40 has good initial friction and can provide stable support for the jigsaw pieces, significantly improving the stability and operation experience of the jigsaw, especially for complex and large-numbered jigsaws, ensuring that the pieces are not easily moved or displaced during the assembly process;

[0044] Deal with the difficulty of cleaning: due to the fact that the felt material easily absorbs dust and hair and is difficult to clean, the design enables the user to regularly remove the work layer 40 for separate cleaning or directly replace a new work layer 40 through the detachable frame 30, which not only maintains the appearance of the jigsaw board, but also always maintains the good friction between the jigsaw pieces and the surface of the work layer 40, ensuring smooth jigsaw operation and improving the overall use effect of the jigsaw board.

[0045] In the embodiment of the utility model, the frame 30 is magnetically attracted to the jigsaw board body 10;

[0046] The magnetic attraction connecting assembly is arranged between the puzzle plate body 10 and the frame 30, and the stable magnetic attraction of the frame 30 and the puzzle plate body 10 is realized through the magnetic attraction connecting assembly.

[0047] The magnetic attraction connecting assembly comprises a permanent magnet component arranged at the edge of the puzzle plate body 10 and a magnetic matching component arranged at the corresponding position of the frame 30.

[0048] The permanent magnet component is a permanent magnet block or a distributed permanent magnet particle, and the magnetic matching component is a metal sheet or a magnetic rubber sheet that can be attracted by the permanent magnet or another magnet component with opposite magnetic poles to the permanent magnet component.

[0049] By using the opposite attraction characteristics of the magnetic material, the magnetic attraction connecting assembly is arranged at the corresponding positions of the frame 30 and the puzzle plate body 10, for example, the permanent magnet is embedded at the edge of the puzzle plate body 10, and the metal sheet that can be attracted or the magnet with opposite magnetic poles is arranged at the corresponding position of the frame 30, and the like. This design constructs a connection mode without complex mechanical structure, and the user only needs to place the frame 30 close to the puzzle plate body 10, and the magnetic force can automatically guide and realize the quick connection of the two, greatly simplifying the installation process of the frame 30 and improving the convenience of user operation.

[0050] In addition, the magnetic attraction can adapt to the slight size deviation or position error of the puzzle plate body 10 and the frame 30 generated in the manufacturing and installation process to a certain extent. Since the magnetic force has a certain elasticity, when the positions of the two are slightly deviated, the magnetic force can automatically adjust the position of the frame 30 to accurately fit the puzzle plate body 10, so that the working layer 40 is uniformly pressed and the working state is maintained.

[0051] Preferably, the detachable connection mode of the puzzle plate body 10 and the frame 30 can also be a buckle, a screw or the like, which is not limited herein. The utility model preferably adopts the magnetic attraction mode, so that the user can quickly complete the installation and removal operation of the frame 30 by hand during use, without the aid of additional tools. For users who frequently replace the working layer 40, this feature greatly saves the operation time and significantly improves the use efficiency.

[0052] In the embodiment of the utility model, the working layer 40 is a felt layer, and the felt layer covers the surface of the area for splicing the puzzle of the puzzle plate body 10.

[0053] As described above, the working layer 40 is a felt layer, and the felt layer has a unique fiber structure. The fibers are interwoven to form an irregular surface. When the puzzle pieces are placed on the surface of the felt layer, a large friction force is generated between the pieces and the felt fibers. Covering the felt layer on the surface of the area for splicing the puzzle of the puzzle plate body 10 utilizes this friction force characteristic to provide a stable placement basis for the puzzle pieces.

[0054] The area of the puzzle board body 10 for splicing the puzzle is the core part of the puzzle operation, and the felt layer is accurately covered on the area, which can closely fit the surface profile of the puzzle board body 10, fully utilize the space of the area, and provide a complete and suitable working plane for the puzzle; meanwhile, since the felt material has a certain flexibility, it can better adapt to the possible slight unevenness of the surface of the puzzle board body 10, further ensure good contact with the puzzle pieces, enhance the friction effect, and ensure smooth puzzle process.

[0055] In the embodiment of the utility model, the puzzle board body 10 is provided with a hinge structure along the axis thereof, so that the puzzle board body 10 can be folded in half.

[0056] The frame 30 is correspondingly divided into a first half frame 301 and a second half frame 302 along the central axis of the puzzle board body 10.

[0057] The hinge structure (such as a hinge) is arranged along the central axis of the puzzle board body 10 to realize folding of the puzzle board body 10 in half. This design is inspired by the principle of common folding furniture, and the component is folded by rotating at the hinge point. When the puzzle board is not used or needs to be stored, the user can fold the puzzle board body 10 in half along the hinge structure, effectively reducing the occupied area of the puzzle board in space. For users with limited space at home or who need to frequently move the puzzle board, this design can flexibly adjust the spatial form of the puzzle board to meet the spatial needs in different scenarios.

[0058] In order to cooperate with the folding function of the puzzle board body 10, the frame 30 is correspondingly divided into a first half frame 301 and a second half frame 302 along the central axis of the puzzle board body 10. This design ensures that the frame 30 can be adapted accordingly when the puzzle board body 10 is folded. When the puzzle board body 10 is folded in half, the first half frame 301 and the second half frame 302 can be close to each other and docked, continuing to play the role of the frame 30 in pressing and fixing the working layer 40, while maintaining the integrity of the overall structure. The design principle is to synchronize and cooperate the folding action of the frame 30 and the puzzle board body 10, and maintain the functional consistency of the product in different states.

[0059] Preferably, at the butt joint of the first half frame 301 and the second half frame 302, a corresponding connecting mechanism can be designed, for example, a magnetic attraction strip matched with each other can be arranged on the opposite edges of the first half frame 301 and the second half frame 302 respectively, and when the puzzle plate body 10 is folded, the magnetic attraction strips are automatically attracted to make the two half frames 30 tightly connected, which is simple to operate and stable in connection; or a buckle type butt joint structure can be designed, a protruding buckle is arranged on the first half frame 301, and a groove slot is arranged at the corresponding position of the second half frame 302, when folding, the protruding buckle is precisely embedded in the groove slot to realize reliable connection and prevent accidental separation of the two half frames 30 during movement or use; or a design with a gap can be used, when the puzzle plate body 10 is folded, the first half frame 301 and the second half frame 302 are close to each other but not completely attached, and a gap with a certain width is reserved in the middle, this design is mainly based on the consideration of material thermal expansion and contraction and production and manufacturing tolerance, under different environmental temperatures, the puzzle plate material may expand and contract due to heat, the gap can provide space for the expansion and contraction of the frame 30 material, prevent the frame 30 from deforming or being damaged due to thermal expansion; at the same time, due to process limitations, there may be a small deviation in the size of the half frame 30 during production and manufacturing, the existence of the gap can effectively accommodate these tolerances, so that the two half frames 30 can still be relatively smoothly butted in the folded state, maintain the stability of the product structure, and when folding, the gap will not affect the pressing and fixing effect of the frame 30 on the working layer 40, keep the integrity of the overall structure, make the folding action of the frame 30 and the puzzle plate body 10 synchronous and cooperative, and maintain the functional consistency of the product in different states.

[0060] In the embodiment of the utility model, the surface of the puzzle plate body 10 is provided with a boss structure 50, the upper surface of the boss structure 50 constitutes the placement plane of the working layer 40, and a stepped groove 501 matched with the frame 30 is arranged around the periphery of the boss, and the frame 30 can be embedded in the stepped groove 501.

[0061] The boss structure 50 is arranged on the surface of the puzzle plate body 10, the upper surface of the boss structure 50 serves as a placement area of the working layer 40, the boss separates the working layer 40 from other parts of the puzzle plate body 10, reduces the influence of structural changes of other parts of the body on the flatness of the working layer 40, provides stable support for the working layer 40, and ensures that the working layer 40 always remains flat; the step groove 501 is arranged around the periphery of the boss, the step groove 501 is matched in size and shape with the frame 30, when the frame 30 is installed, the frame 30 is embedded (or can be considered as being clamped or placed) into the step groove 501, the step groove 501 plays a positioning role on the frame 30, for the puzzle plate using magnetic attraction connection, the frame 30 is first positioned through the step groove 501, and then the magnetic attraction connection assembly is used to connect the puzzle plate body 10 and the frame 30; the step groove 501 ensures that the frame 30 is accurately positioned during installation, so that the magnetic poles of the magnetic attraction assembly can be correctly matched, thereby enhancing the stability of the magnetic attraction connection, and further ensuring the pressing effect of the frame 30 on the working layer 40.

[0062] In the embodiment of the utility model, the frame 30 has a pressing part 303 and a connecting part 304 which are integrated;

[0063] The pressing part 303 corresponds to the placement plane of the boss structure 50 on the surface of the puzzle plate body 10, and is used for pressing the working layer 40 arranged on the placement plane;

[0064] The connecting part 304 corresponds to the step groove 501 around the periphery of the boss structure 50, and is used for being embedded into the step groove 501, so as to realize the stable connection between the frame 30 and the puzzle plate body 10.

[0065] The pressing part 303 corresponds to the placement plane of the boss structure 50 on the surface of the puzzle plate body 10, and is used for pressing the working layer 40 arranged on the placement plane;

[0066] The connecting part 304 is matched with the stepped groove 501 around the boss structure 50, and is embedded in the stepped groove 501 to realize preliminary positioning during installation. Preferably, a magnetic attraction connecting assembly is arranged on the connecting part 304, such as small magnets or magnetic materials distributed on the inner side surface of the connecting part 304. Correspondingly, the stepped groove 501 of the jigsaw puzzle body 10 is embedded with metal sheets or magnetic materials that are attracted to each other. When the connecting part 304 is embedded in the stepped groove 501, the magnetic attraction assembly is attracted to each other to generate a magnetic force connection. In this process, the connecting part 304 is stably attached in the stepped groove 501 due to the magnetic force, and at the same time, the stable force is transmitted. Since the connecting part 304 and the pressing part 303 are integrated structures, the stability of the connecting part 304 drives the pressing part 303 to act more closely on the working layer 40, giving the pressing part 303 an additional pressure, so that the pressing part 303 can better tightly press the working layer 40 on the placement plane of the boss structure 50, preventing the working layer 40 from being displaced or wrinkled.

[0067] In the embodiment of the utility model, the frame 30 surrounds to form the slot position 502 corresponding to the working layer 40, and the cover plate 60 detachably connected with the jigsaw puzzle body 10 is arranged on the slot position 502.

[0068] When the jigsaw puzzle operation is not performed, the cover plate 60 is tightly pressed on the working layer 40 in the slot position 502 to fix the jigsaw puzzle above the working layer 40. Preferably, the cover plate 60 is magnetically attracted and matched with the jigsaw puzzle body 10.

[0069] The cover plate 60 detachably connected with the jigsaw puzzle body 10 is arranged on the slot position 502 surrounded by the frame 30 corresponding to the working layer 40, and the main purpose is to protect the jigsaw puzzle already assembled on the working layer 40 when the jigsaw puzzle operation is not performed. When the cover plate 60 is placed on the slot position 502, a certain pressure is applied to the working layer 40 by virtue of its own gravity and the magnetic force generated by the magnetic attraction and matching with the jigsaw puzzle body 10. This pressure can effectively prevent the jigsaw puzzle pieces from being displaced and scattered due to external force collision, vibration or accidental touch, and will not damage the jigsaw puzzle or the working layer 40 due to excessive pressure. The cover plate 60 is designed to be magnetically attracted and matched with the jigsaw puzzle body 10, which utilizes the convenience and stability of the magnetic force. When the cover plate 60 needs to be covered or removed, the user only needs to approach or move away gently, and the magnetic force can realize rapid connection and separation. At the same time, the magnetic force can ensure that the cover plate 60 is accurately aligned with the slot position 502 when placed, and maintains a stable pressure application state during use, continuously providing reliable protection for the jigsaw puzzle. The cover plate 60 can be a flexible plate material with magnetic ability, and the jigsaw puzzle body 10 is internally provided with a corresponding magnetic component matched with the cover plate 60 (the permanent magnet component at the edge of the jigsaw puzzle body 10 is distinguished from each other in spatial position, so as to avoid magnetic attraction conflict).

[0070] The design is closely adapted to the operation process of the puzzle, and in the process of the puzzle, the user can easily detach the cover plate 60 and place it aside, without causing any hindrance to the puzzle operation, and when the puzzle is temporarily interrupted or a part is completed and needs to be saved, the cover plate 60 can be quickly installed on the slot 502 through magnetic attraction, and the puzzle on the working layer 40 is properly protected by exerting moderate pressure, seamlessly connects different stages of the puzzle, and provides the user with a convenient and efficient puzzle experience.
