Description

[Technical Field]

[0001] This application belongs to the field of office stationery technology, specifically relating to a magnetic chess piece with assembleable accessories. [Background Technology]

[0002] In everyday office and teaching environments, magnetic fasteners are commonly used to secure items such as paper, photos, or sticky notes to ferromagnetic surfaces like metal panels, whiteboards, or refrigerators. Existing magnetic fasteners, such as common magnetic chess pieces, rely primarily on the magnetic attraction generated by their internal magnets to press the items onto the ferromagnetic surface. This method is simple to operate and avoids the perforation or damage to the mounting surface that traditional thumbtacks can cause. However, when the items to be secured are thicker, such as a stack of multi-page documents, a booklet, a piece of corkboard, or a fabric sample, the thickness of the item significantly increases the distance between the magnetic fastener and the ferromagnetic surface, resulting in a sharp decrease in magnetic field strength and a corresponding significant reduction in the attraction force. This makes the magnetic chess pieces easily displaced or even fall off due to slight touches or vibrations, failing to achieve effective and secure fixation of thicker items, thus limiting its application scenarios. Therefore, how to solve the problem of insufficient attraction force when fixing thicker items, based on this convenient magnetic fastening method, has become a technical problem that urgently needs improvement. [Utility Model Content]

[0003] In order to address the problem of insufficient magnetic attraction when fixing thicker items, this application provides a magnetic chess piece with assembleable accessories.

[0004] This application is achieved through the following technical solution:

[0005] A magnetic chess piece with assembleable accessories includes a chess piece body and a magnetic component. The chess piece body has a mounting groove for embedding the magnetic component. The top of the chess piece body has a through hole that connects to the mounting groove and allows a thumbtack to be inserted. The thumbtack passes through an item and the through hole in sequence and is then inserted into the magnetic component to fix the item between the chess piece body and the thumbtack.

[0006] As described above, in an assemblable magnetic chess piece, the outer contour shape of the magnetic component is adapted to the contour shape of the mounting groove, and the depth of the mounting groove is adapted to the thickness of the magnetic component.

[0007] A magnetic chess piece with assembleable components as described above, wherein the magnetic component is magnetic adhesive.

[0008] The magnetic chess piece with assembleable parts as described above also includes an adsorption component, and the top of the chess piece body is provided with a recessed assembly platform for the adsorption component.

[0009] As described above, in one type of magnetic chess piece with assemblable components, the assembly platform is lowered to form a barrier along the top outer edge of the chess piece body, the barrier being used to restrict the adsorption component from detaching laterally from the assembly platform.

[0010] As described above, in an assemblable magnetic chess piece, the thickness of the adsorption element is greater than or equal to the height of the enclosure.

[0011] As described above, a magnetic chess piece with assemblable components has a magnetic adsorption element disposed on the assembly platform to be attracted by the magnetic element located in the mounting groove.

[0012] As described above, in an assemblable magnetic chess piece, the through hole is located in the middle of the assembly platform.

[0013] As described above, a magnetic chess piece with assembleable parts, the main body of which is made of plastic material.

[0014] As described above, a magnetic chess piece with an assemblable accessory, wherein the adsorption element is made of a flexible material.

[0015] Compared with the prior art, this application has the following advantages:

[0016] This application discloses a magnetic chess piece with assemblable accessories. By creating a through hole in the chess piece's main body that connects to the magnetic mounting slot and allows a tack to pass through, it achieves a combination of magnetic adsorption and mechanical fixation. When dealing with thinner documents, the magnetic force of the magnetic component alone can be used for quick and easy adsorption and fixation. When it is necessary to fix thicker or heavier items, the user can pass the tack through the first through hole on the item and the chess piece's main body in sequence, and finally insert it into the magnetic component. At this time, the item is firmly clamped between the tack head and the chess piece's main body, no longer relying solely on the magnetic force that is severely weakened by the thickness of the item. This allows it to reliably fix a variety of items such as documents, fabrics, and cork sheets of various thicknesses, and provides a safer and more stable fixation effect, preventing items from slipping due to accidental touch or vibration. At the same time, it retains the advantages of magnetic chess pieces themselves, such as easy positioning and movement on ferromagnetic panels, without damaging the mounting surface, and has significant practicality and flexibility.

Detailed Implementation Methods

[0028] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0029] Please see Figures 1 to 10 A magnetic chess piece with assembleable accessories includes a chess piece body 1 and a magnetic component 2. The chess piece body 1 is provided with an installation groove 11 for the magnetic component 2 to be inserted. The top of the chess piece body 1 is provided with a through hole 12 that connects to the installation groove 11 and allows a thumbtack to be inserted. The thumbtack passes through an item and the through hole 12 in sequence and is then inserted into the magnetic component 2 to fix the item between the chess piece body 1 and the thumbtack.

[0030] This application discloses a magnetic chess piece with assemblable accessories. By creating a through hole in the chess piece's main body that connects to the magnetic mounting slot and allows a tack to pass through, it achieves a combination of magnetic adsorption and mechanical fixation. When dealing with thinner documents, the magnetic force of the magnetic component alone can be used for quick and easy adsorption and fixation. When it is necessary to fix thicker or heavier items, the user can pass the tack through the first through hole on the item and the chess piece's main body in sequence, and finally insert it into the magnetic component. At this time, the item is firmly clamped between the tack head and the chess piece's main body, no longer relying solely on the magnetic force that is severely weakened by the thickness of the item. This allows it to reliably fix a variety of items such as documents, fabrics, and cork sheets of various thicknesses, and provides a safer and more stable fixation effect, preventing items from slipping due to accidental touch or vibration. At the same time, it retains the advantages of magnetic chess pieces themselves, such as easy positioning and movement on ferromagnetic panels, without damaging the mounting surface, and has significant practicality and flexibility.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the outer contour shape of the magnetic component 2 is adapted to the contour shape of the mounting groove 11, and the depth of the mounting groove 11 is adapted to the thickness of the magnetic component 2.

[0032] In this embodiment, the precise fit of shape and size ensures that the magnetic component is securely embedded in the chess piece body, effectively preventing it from shaking, rotating, or accidentally falling off during installation, use, or impact, thus guaranteeing the integrity and durability of the product structure. Secondly, this seamless fit allows the bottom surface of the magnetic component to be flush with the bottom of the chess piece body, thereby minimizing the non-magnetic gap between the magnetic component and the ferromagnetic panel, ensuring maximum and effective transmission of magnetic force, and providing the strongest magnetic support for securing thin documents.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the magnetic component 2 is magnetic adhesive.

[0034] In this embodiment, the inherent magnetic properties of the magnetic adhesive, combined with its rubber-like flexibility and elasticity, fundamentally solve the technical problem that repeated punctures of traditional sintered hard magnets easily lead to magnet breakage or permanent damage. When the tack passes through the hole in the object or chess piece, its tip easily penetrates the soft magnetic adhesive. The adhesive material, due to its elasticity, tightly wraps around and holds the tack, forming a stable and effective mechanical fixation. When the tack is pulled out, the puncture hole in the magnetic adhesive can retract or even close due to the material's elastic memory and self-healing ability. This allows the same location to withstand multiple punctures without significantly reducing subsequent clamping force, greatly enhancing the product's durability and reliability, and significantly extending its service life.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes an adsorption element 3, wherein the top of the chess piece body 1 is provided with a recessed assembly platform 13 for mounting the adsorption element 3.

[0036] In this embodiment, the assembly platform provides a precise positioning and installation benchmark for the adsorption component, ensuring that the top surface of the adsorption component forms a flat and stable support plane. When the tack passes through the item to be fixed and presses it against the main body of the chess piece, the flat surface formed by the adsorption component can evenly support the item, effectively dispersing the stress of the tack head pressing down. This avoids technical problems such as indentations, wrinkles, or damage to the fixed item, such as paper or photos, caused by uneven surfaces or direct contact with the edge of the through hole, thus achieving the functions of "leveling" and protection. At the same time, as an independent and exposed component, the adsorption component can be designed in various ways in terms of material, color, pattern, or surface texture, making it a decorative element that can enhance the overall aesthetics of the product, differentiate the style of a series of products, or meet the personalized customization needs of users. The material of the adsorption component is set as an elastomer with a high coefficient of friction, such as silicone or soft rubber. This not only further protects the surface of the fixed item through its cushioning properties, but more importantly, it can effectively prevent the fixed item from sliding or rotating under the pressure of the tack by utilizing its high friction, solving the technical problem of the stability of fixing items on smooth surfaces and providing stronger retention reliability.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the assembly platform 13 is lowered to form a barrier 14 on the top outer edge of the chess piece body 1, the barrier 14 being used to restrict the adsorption member 3 from detaching from the assembly platform 13 to the side.

[0038] In this embodiment, the enclosure forms a physical boundary that precisely matches the shape of the adsorption component. When the adsorption component is placed on the assembly platform, the enclosure structure surrounds and locks it from all lateral dimensions. Any lateral external force applied to the adsorption component, such as collisions, friction, or tilting pressure during daily use, will be directly absorbed and resisted by the sturdy enclosure, thereby completely eliminating the possibility of lateral displacement, lifting, or even falling off of the adsorption component, and ensuring a long-term stable bond between it and the main body of the chess piece.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the thickness of the adsorption member 3 is greater than or equal to the height of the enclosure 14.

[0040] In this embodiment, when the thickness of the adsorption component is equal to the height of the enclosure, their top surfaces are flush, providing an absolutely flat support base for the fixed item. When the thickness of the adsorption component is greater than the height of the enclosure, the surface of the adsorption component will protrude slightly from the main body of the chess piece. This "protruding" design makes the adsorption component the primary contact point and visual focus. If the adsorption component is made of soft and skin-friendly materials such as silicone, users can enjoy a more comfortable and non-slip feel. At the same time, this protruding flexible part can also act as a buffer pad when the chess piece falls, absorbing the impact to protect the main structure and solving the problem of bumps and damage that may be caused by accidental drops.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the adsorption element 3 is magnetic and is disposed on the assembly platform 13 to be attracted by the magnetic element 2 located in the mounting groove 11.

[0042] In this embodiment, the magnetic component located in the mounting slot generates a stable magnetic field that penetrates the main material of the chess piece. When a magnetic or magnetically conductive adsorption component is placed on the top assembly platform, it will be attracted by the magnetic field and automatically and firmly adsorbed into place. Compared with glue bonding or snap-fit ​​structures, this magnetic coupling method solves the inherent technical problem of adhesive bonding, namely that the adhesive layer may fail due to aging or changes in temperature and humidity, causing the component to fall off. It also avoids the potential environmental pollution and drag on production efficiency caused by the adhesive bonding process, making the assembly process extremely clean, efficient and instantaneous.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the through hole 12 is located in the middle of the assembly platform 13.

[0044] In this embodiment, the central positioning ensures that when the thumbtack is inserted and fixes the item, the downward pressure generated can be evenly applied and distributed along the entire center of gravity axis of the chess piece. This solves the technical problem that the item may tilt or be unstable due to eccentric force, ensuring that the fixed object can fit flat and firmly without warping or rotating. Secondly, it avoids the deflection torque generated on the chess piece when pressing the thumbtack, thereby eliminating internal stress that may cause structural damage and enhancing the overall structural strength and durability of the product.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation, the main body 1 of the chess piece is made of plastic material.

[0046] In this embodiment, injection molding technology is used to process molten plastic into a chess piece body with complex three-dimensional structures, including mounting grooves, assembly platforms, enclosures, and through holes, in a single, high-precision process. This significantly reduces manufacturing costs and enables large-scale, rapid production, solving the technical problems of complex processing, high costs, and difficulty in mass production of traditional materials such as wood, metal, or ceramics. Secondly, the extremely high plasticity of plastic provides great freedom in design, allowing various intricate structural details to be easily integrated and realized, providing a foundation for the realization and optimization of product functions. Furthermore, plastic's combination of lightweight and high toughness ensures that the product is both lightweight and easy to use, while also possessing good impact resistance and wear resistance, making it less prone to damage during daily use or drops. At the same time, the easy-to-color properties of plastic materials allow the product to present a rich and colorful appearance without secondary painting, with uniform colors that are not easily peeled off.

[0047] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the adsorption element 3 is made of a flexible material.

[0048] In this embodiment, by using a flexible material such as silicone, thermoplastic elastomer (TPE), or soft rubber, when the tack presses an item onto the tack, the flexible material undergoes slight deformation due to its low hardness and high elasticity, thus perfectly fitting and enveloping the fixed item with a larger contact area. Simultaneously, its surface friction coefficient, much higher than that of rigid plastics, generates strong static friction. Furthermore, the tack tip can easily penetrate the tack and enter the through-hole, forming a stable and effective mechanical fixation. When the tack is pulled out, the puncture holes on the magnetic adhesive and the tack can retract or even close due to the elastic memory and self-healing ability of the material. This allows the same location to withstand multiple punctures without significantly reducing subsequent clamping force, greatly enhancing the product's durability and reliability, and significantly extending its service life.

[0049] The working principle of this embodiment is as follows:

[0050] This application discloses a magnetic chess piece with assemblable accessories. By creating a through hole in the chess piece's main body that connects to the magnetic mounting slot and allows a tack to pass through, it achieves a combination of magnetic adsorption and mechanical fixation. When dealing with thinner documents, the magnetic force of the magnetic component alone can be used for quick and easy adsorption and fixation. When it is necessary to fix thicker or heavier items, the user can pass the tack through the first through hole on the item and the chess piece's main body in sequence, and finally insert it into the magnetic component. At this time, the item is firmly clamped between the tack head and the chess piece's main body, no longer relying solely on the magnetic force that is severely weakened by the thickness of the item. This allows it to reliably fix a variety of items such as documents, fabrics, and cork sheets of various thicknesses, and provides a safer and more stable fixation effect, preventing items from slipping due to accidental touch or vibration. At the same time, it retains the advantages of magnetic chess pieces themselves, such as easy positioning and movement on ferromagnetic panels, without damaging the mounting surface, and has significant practicality and flexibility.
