Description

Technical Field

[0001] This application relates to the field of technology, and more specifically to a suction cup base. Background Technology

[0002] In modern office and home environments, the desktop is a frequently used area, but the placement and securing of items on it often presents numerous challenges. For example, water cups and coffee cups are easily knocked over, spilling liquids and wetting important items such as documents and computers; overturned condiment bottles and vases soil the surface, affecting not only aesthetics but also potentially damaging the desktop material; and expensive cosmetics, if spilled and broken, not only cause financial loss but may also pose safety hazards. These common desktop problems seriously impact work efficiency and quality of life. Currently, common desktop storage methods include using ordinary anti-slip mats, double-sided tape / glue, and fixed stands. However, these traditional methods have significant limitations. For example, ordinary anti-slip mats are usually made of rubber or silicone, and their surfaces easily attract dust and stains, making them difficult to clean. After long-term use, the anti-slip mats will become dirty and affect the overall appearance of the desktop. Anti-slip mats can only provide a certain amount of friction to prevent items from sliding, but for larger or heavier items, their fixing effect is not ideal, and they cannot effectively prevent items from shifting or tipping over due to collisions or vibrations. While double-sided tape and glue can fix items, they often leave glue residue that is difficult to clean when removed, and may even damage the desktop surface, especially for wooden or smooth desktop materials.

[0003] To address the aforementioned issues, Chinese utility model patent CN205978027U discloses a suction cup structure, including a support base and a suction cup body that can deform under external force. The key feature is that a groove is provided on the lower surface of the support base, and the suction cup body is mounted on the port of the groove via a connector and protrudes outward from the groove. A pulling component for twisting the suction cup body is also provided between the suction cup body and the support base. In this technical solution, the suction cup body can be firmly adhered to the desktop by gravity, and can be easily de-adsorbed by the pulling component, greatly simplifying the suction cup structure. Furthermore, the adsorption and de-adsorption operations are simple, providing not only a fixing function but also preventing damage to the desktop after de-adsorption. However, the suction cup body is connected to the support base via a columnar rod connector. This connection method transmits gravity only through the columnar rod at the center, causing the force on the suction cup body to be concentrated at the center point, while the force on other parts is relatively small. This makes it difficult for the parts other than the center point to adhere tightly to the table when the suction cup is adsorbed, thus reducing the reliability and stability of the adsorption. The effective utilization rate of the adsorption area of ​​the suction cup body is low, making it difficult to fully utilize the adsorption capacity of the suction cup and easily resulting in weak adsorption. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a suction cup base that transmits force evenly to the entire surface of the first plate through the second plate, so that the edge part of the first plate can also be closely attached to the surface to be adsorbed, which significantly improves the firmness and reliability of adsorption.

[0005] This application provides a suction cup base, including a support base and a suction cup assembly. The suction cup assembly includes a first disc and a second disc, with the second disc located above the first disc. The first disc is used to adsorb the surface to be adsorbed. The second disc is movably connected to the support base. The support base is subjected to force through the second disc, which acts on the first disc to cause the first disc to adsorb or desorb from the surface to be adsorbed.

[0006] In this technical solution, the support base is used to place and fix the object to be fixed, including but not limited to water cups, mobile phones, pencil sharpeners, condiment bottles, and skin care products. The suction cup assembly consists of a first plate and a second plate, and is the core part for achieving the adsorption function. The first plate directly contacts the surface to be adsorbed, and its surface can adsorb onto the surface, including but not limited to desktops, walls, and workbenches. The second plate is positioned above the first plate and is movably connected to the support base. The function of the second plate is to evenly transfer the force on the support base to the first plate, enabling the first plate to better achieve adsorption or desorption. The entire surface of the first plate can be evenly stressed, thus overcoming the limitation of traditional suction cups where the force is only applied through the central connector, resulting in uneven adhesion. To address the issue of insufficient force at the edges, uniform force distribution allows the first disc to better adhere to the surface to be adsorbed, forming a tighter seal and improving the strength and reliability of adsorption. When the support is subjected to pressure, the second disc transmits the force to the first disc, causing the first disc to adhere tightly to the surface to be adsorbed. After air is expelled, a negative pressure is created, thus firmly adsorbing onto the surface to be adsorbed. When the support is subjected to tension, the second disc causes the first disc to deform, breaking the seal between the adsorption surface and the surface to be adsorbed. Air enters and releases the negative pressure, thereby achieving desorption. The force is evenly transmitted to the entire surface of the first disc through the second disc, allowing the edges of the first disc to also adhere tightly to the surface to be adsorbed, significantly improving the strength and reliability of adsorption.

[0007] As an improvement, the first disc is a flexible disc, and the second disc is a rigid disc. In this technical solution, the first disc can be made of highly elastic silicone, rubber, or other flexible materials, possessing good deformation capacity and sealing performance. The first disc deforms to fit tightly against the surface to be adsorbed, creating negative pressure after air is expelled, thereby achieving firm adsorption. The second disc can be made of plastic, metal, or other rigid materials, possessing high strength and stability. The rigid material of the second disc ensures that the force of the support is evenly transmitted to the entire surface of the first disc, ensuring that the first disc can be evenly stressed and achieve reliable adsorption or desorption. The combination of the rigid second disc and the flexible first disc results in a simple structure and improved adsorption efficiency.

[0008] As an improvement, the support base is provided with a first hook, and the second disc is provided with a second hook adapted to the first hook. The first and second hooks are connected to allow the second disc to be movably connected to and locked with the support base. The support base pulls the second disc by cooperating with the first hook, causing the first disc to detach from the surface to be adsorbed. In this technical solution, the first hook is provided on the support base and the second hook is provided on the second disc. The first and second hooks are tightly engaged to ensure a firm connection between the two, preventing them from loosening or falling off during use. This ensures the overall stability and reliability of the suction cup base, while allowing a certain range of motion, enabling the support base to move within a certain range, thereby deforming the second and first discs to achieve adsorption and desorption operations. Through the cooperation of the second and first hooks, the support base can pull the second disc, thereby deforming the first disc, breaking the seal between the first disc and the surface to be adsorbed, allowing air to enter, thus relieving the negative pressure and achieving desorption. The design of the first and second hooks reduces complex connecting parts and assembly steps, lowering manufacturing and assembly costs.

[0009] As an improvement, the support base is provided with an abutment portion adapted to the second disc. When the support base is pressed, it abuts against the second disc through the abutment portion, causing the first disc to adhere to the surface to be adsorbed. In this technical solution, the abutment portion is located on the support base and adapted to the second disc. Its main function is to transmit the pressing pressure received by the support base to the second disc. The abutment portion has a circular protruding structure, allowing it to make close contact with the outer edge of the second disc, ensuring uniform force transmission. The size of the abutment portion is adapted to the size of the second disc, ensuring that during pressing, the abutment portion can completely cover the outer edge of the second disc, avoiding uneven force transmission or localized stress concentration caused by size mismatch. Due to the close contact between the abutment portion and the outer edge of the second disc, the pressing pressure can be evenly transmitted to the entire surface of the second disc, thereby allowing the first disc to be evenly stressed and achieving a better adsorption effect.

[0010] As an improvement, the first disc body is provided with a first connecting post, and the second disc body is provided with a through hole for the connecting post to pass through. The first connecting post has a hollow structure, and the support base is provided with a second connecting post adapted to the first connecting post. The second connecting post is inserted into the first connecting post to connect the support base and the first disc body. In this technical solution, a first connecting post is provided on the first disc body, located at the center of the first disc body and extending axially in the opposite direction to the adsorption surface. A through hole is provided on the second disc body, the size and shape of which are adapted to the first connecting post to ensure a tight fit. The first connecting post has a hollow structure, and a second connecting post is provided on the support base that can be inserted into the first connecting post. The hollow structure of the first connecting post provides space for the movement of the second connecting post, allowing the support base to move relative to the suction cup assembly, ensuring sufficient gap between the two so that the second connecting post can move smoothly without affecting the stability of the connection due to excessive gap.

[0011] As an improvement, a connector is installed on the support base. The connector is used to connect items and prevent them from tipping over. In this technical solution, the main function of the connector is to connect items and prevent them from tipping over. The connector provides stable support through direct contact with the items. The connector can be connected to the items in various ways, such as by clamping, hooking, magnetic attraction, or adhesive, effectively preventing items from tipping over due to external forces during use. It is particularly suitable for placing fragile items (such as glass cups, vases, etc.) or valuable items (such as electronic products, cosmetics, etc.).

[0012] As an improvement, the connector can be an adhesive, a magnetic, or a fitting. In this technical solution, the specific selection of the connector can be adjusted according to usage requirements, including but not limited to adhesives, magnetics, and fittings. Adhesives are typically made of high-performance adhesive materials, such as nano-adhesives and pressure-sensitive adhesives, which adhere tightly to the surface of the object to achieve fixation. Adhesives are characterized by high adhesion, strong durability, easy peeling, and no residue. Magnetics are made of magnetic materials, such as neodymium iron boron magnets, which are characterized by high magnetism and good stability. Magnetics are fixed by magnetic attraction to the surface of the object and are suitable for metal objects, such as stainless steel cups and iron tools. Fittings are fixed by engaging with the fitting structure of the object (such as slots or grooves). Fittings can be designed as modular structures to adapt to the shape and size of different objects and are suitable for objects with specific fitting structures, such as electronic products with slots or tools with grooves, meeting various usage requirements.

[0013] As an improvement, the first and second discs are integrally molded structures. In this technical solution, the first and second discs are manufactured through an integral molding process to form a single structure, eliminating the connection gaps and assembly errors that may exist in traditional split structures, thus improving the overall stability and reliability. Integral molding can be achieved through various processes, including but not limited to overmolding, two-color injection molding, and thermoforming, which can combine different materials (such as rigid and flexible materials) to form a seamless structure. This application preferably uses overmolding, which is a molding process that wraps a flexible material around a rigid material, achieving a combination of rigid and flexible materials. This not only improves the stability of the structure but also reduces assembly steps and costs, and increases production efficiency.

[0014] As an improvement, the diameter of the first disc is larger than the diameter of the second disc, the first disc has a flat portion for fitting the second disc, and the cross-section of the first disc is trapezoidal. In this technical solution, setting the diameter of the first disc to be larger than the diameter of the second disc allows the first disc to cover a larger adsorption area, thereby providing stronger adsorption force. At the same time, the second disc, as a rigid support, can better transmit force. The flat portion of the first disc for fitting the second disc ensures close contact between the first and second discs, allowing force to be transmitted evenly. The trapezoidal cross-section of the first disc allows the edge of the first disc to better fit with the surface to be adsorbed, forming a tighter seal, thereby improving the firmness and reliability of adsorption.

[0015] As an improvement, the bottom outer edge of the second disc is provided with an annular protrusion, and the first disc is provided with an annular groove adapted to the annular protrusion. The annular protrusion and the annular groove are connected. In this technical solution, the annular protrusion is located on the outer edge of the bottom of the second disc, and its shape and size are designed to match the annular groove on the first disc. The annular protrusion can be accurately embedded in the annular groove, realizing a tight connection between the first disc and the second disc. The design of the annular protrusion and the annular groove can be completed in one step during the manufacturing process, reducing assembly steps and costs. It is particularly suitable for one-piece molding processes such as overmolding and injection molding, improving the tightness of the connection and the structural strength.

[0026] like Figures 1 to 5As shown, this application discloses a suction cup base, including a support base 1 and a suction cup assembly. The suction cup assembly includes a first disc 2 and a second disc 3, with the second disc 3 located above the first disc 2. The first disc 2 is used to adsorb the surface to be adsorbed. The second disc 3 is movably connected to the support base 1. The force on the support base 1 is applied to the first disc 2 through the second disc 3, causing the first disc 2 to adsorb or desorb from the surface to be adsorbed. The support base 1 is used to place and fix the object to be fixed, including but not limited to water cups, mobile phones, pencil sharpeners, condiment bottles, and skin care products. The suction cup assembly, composed of the first disc 2 and the second disc 3, is the core part for realizing the adsorption function. The first disc 2 is in direct contact with the surface to be adsorbed, and the surface of the first disc 2 can adsorb onto the surface to be adsorbed, including but not limited to desktops, walls, and workbenches. The second disc 3 is positioned above the first disc 2 and movably connected to the support base 1. The function of the second disc 3 is to evenly transmit the force on the support base 1. The first disc 2 can better achieve adsorption or desorption. The entire surface of the first disc 2 can be evenly stressed, thus overcoming the problem of insufficient stress on the edges caused by the traditional suction cup only being stressed through the central connector 4. The even stress allows the first disc 2 to better adhere to the surface to be adsorbed, forming a tighter seal and improving the firmness and reliability of adsorption. When the support base 1 is subjected to pressure, the second disc 3 transmits the force to the first disc 2, making the first disc 2 fit tightly to the surface to be adsorbed. After the air is expelled, a negative pressure is formed, thus firmly adsorbing onto the surface to be adsorbed. When the support base 1 is subjected to tension, the second disc 3 causes the first disc 2 to deform, breaking the seal between the adsorption surface and the surface to be adsorbed. After the air enters, the negative pressure is released, thus achieving desorption. The force is evenly transmitted to the entire surface of the first disc 2 through the second disc 3, so that the edges of the first disc 2 can also fit tightly to the surface to be adsorbed, significantly improving the firmness and reliability of adsorption.

[0027] More specifically, the first disc 2 is a flexible disc, and the second disc 3 is a rigid disc. The first disc 2 can be made of highly elastic silicone, rubber, or other flexible materials, which have good deformation ability and sealing performance. The first disc 2 deforms and fits tightly with the surface to be adsorbed, and forms a negative pressure after the air is discharged, thereby achieving firm adsorption. The second disc 3 can be made of plastic, metal, or other rigid materials, which have high strength and stability. The second disc 3 uses a rigid material to evenly transmit the force of the support 1 to the entire surface of the first disc 2, ensuring that the first disc 2 can be evenly stressed and achieve reliable adsorption or desorption. Through the combination of the rigid second disc 3 and the flexible first disc 2, the structure is simple and the adsorption efficiency is improved.

[0028] More specifically, such as Figures 2 to 4As shown, the support base 1 is provided with a first hook 11, and the second disc 3 is provided with a second hook 31 that matches the first hook 11. The first hook 11 and the second hook 31 are connected to make the second disc 3 movably connected to and locked with the support base 1. The support base 1 pulls the second disc 3 through the cooperation of the second hook 31 and the first hook 11, so that the first disc 2 is separated from the surface to be adsorbed. The first hook 11 is provided on the support base 1 and the second hook 31 is provided on the second disc 3. The first hook 11 and the second hook 31 are tightly engaged to ensure that the two can be firmly connected and will not loosen or fall off during use, thereby ensuring The design ensures the overall stability and reliability of the suction cup base while allowing a certain range of motion, enabling the support base 1 to move within a certain range. This causes the second disc 3 and the first disc 2 to deform, facilitating adsorption and desorption operations. Through the cooperation of the second hook 31 and the first hook 11, the support base 1 can pull the second disc 3, thereby causing the first disc 2 to deform, breaking the seal between the first disc 2 and the surface to be adsorbed, allowing air to enter, thus relieving the negative pressure and achieving desorption. The design of the first hook 11 and the second hook 31 reduces the complexity of the connecting parts 4 and assembly steps, lowering manufacturing and assembly costs.

[0029] More specifically, such as Figures 2 to 4 As shown, the support base 1 is provided with an abutment portion 12 adapted to the second disc 3. When the support base 1 is pressed, it abuts against the second disc 3 through the abutment portion 12, causing the first disc 2 to adhere to the surface to be adsorbed. The abutment portion 12 is provided on the support base 1 and adapted to the second disc 3. Its main function is to transmit the pressing pressure received by the support base 1 to the second disc 3. The abutment portion 12 has a circular protrusion structure, which allows the abutment portion 12 to make close contact with the outer edge of the second disc 3, ensuring uniform force transmission. The size of the abutment portion 12 is adapted to the size of the second disc 3, ensuring that during the pressing process, the abutment portion 12 can completely cover the outer edge of the second disc 3, avoiding uneven force transmission or local stress concentration caused by size mismatch. Due to the close contact between the abutment portion 12 and the outer edge of the second disc 3, the pressing pressure can be evenly transmitted to the entire surface of the second disc 3, thereby making the first disc 2 evenly stressed and achieving a better adsorption effect.

[0030] More specifically, such as Figures 2 to 5As shown, the first disc 2 is provided with a first connecting post 21, and the second disc 3 is provided with a through hole 32 for the connecting post to pass through. The first connecting post 21 has a hollow structure. The support base 1 is provided with a second connecting post 13 that is adapted to the first connecting post 21. The second connecting post 13 is inserted into the first connecting post 21 to connect the support base 1 and the first disc 2. The first connecting post 21 is provided on the first disc 2. The first connecting post 21 is located at the center of the first disc 2 and extends in the opposite direction to the adsorption surface along the axial direction. The through hole 32 is provided on the second disc 3. The size and shape of the through hole 32 are adapted to the first connecting post 21 to ensure that the two can fit tightly. The first connecting post 21 has a hollow structure. The second connecting post 13 that can be inserted into the first connecting post 21 is provided on the support base 1. The hollow structure of the first connecting post 21 provides space for the movement of the second connecting post 13, allowing the support base 1 to move relative to the suction cup assembly, ensuring that there is enough gap between the two so that the second connecting post 13 can move smoothly, while not affecting the stability of the connection due to excessive gap.

[0031] More specifically, such as Figure 2 and Figure 3 As shown, a connector 4 is installed on the support base 1. The connector 4 is used to connect items and prevent them from tipping over. The main function of the connector 4 is to connect items and prevent them from tipping over. The connector 4 provides stable support through direct contact with the items. The connector 4 can be connected to the items in various ways, such as by clamping, hooking, magnetic attraction or adhesive, to effectively prevent the items from tipping over due to external force during use. It is especially suitable for placing fragile items (such as glass cups, vases, etc.) or valuable items (such as electronic products, cosmetics, etc.).

[0032] More specifically, connector 4 can be an adhesive component, a magnetic component, or a fitting component. The specific selection of connector 4 can be adjusted according to usage requirements, including but not limited to adhesive components, magnetic components, and fitting components. Adhesive components are usually made of high-performance adhesive materials, such as nano-adhesives and pressure-sensitive adhesives. They adhere tightly to the surface of the object through adhesion to achieve fixation. Adhesive components have the characteristics of high adhesion, strong durability, easy peeling, and no residue. Magnetic components are made of magnetic materials, such as neodymium iron boron magnets, and have the characteristics of high magnetism and good stability. Magnetic components are fixed by magnetic attraction to the surface of the object. They are suitable for metal objects, such as stainless steel cups and iron tools. Fitting components are fixed by cooperating with the fitting structure of the object (such as slots, grooves, etc.). Fitting components can be designed as modular structures to adapt to the shape and size of different objects. They are suitable for objects with specific fitting structures, such as electronic products with slots and tools with grooves, to meet a variety of usage requirements.

[0033] More specifically, the first disc 2 and the second disc 3 are integrally molded structures. The first disc 2 and the second disc 3 are manufactured through an integral molding process to form an integral structure, eliminating the connection gaps and assembly errors that may exist in traditional split structures, and improving the overall stability and reliability. Integral molding can be achieved through various processes, including but not limited to overmolding, two-color injection molding, and hot pressing, which can combine different materials (such as rigid materials and flexible materials) to form a seamless structure. This application prefers overmolding, which is a molding process that wraps a flexible material around a rigid material, realizing the combination of rigid and flexible materials. This not only improves the stability of the structure, but also reduces assembly steps and costs, and improves production efficiency.

[0034] More specifically, such as Figures 2 to 5 As shown, the diameter of the first disc 2 is larger than the diameter of the second disc 3. The first disc 2 has a flat portion 22 for adhering to the second disc 3. The cross-section of the first disc 2 is trapezoidal. The larger diameter of the first disc 2 than the second disc 3 allows the first disc 2 to cover a larger adsorption area, thereby providing stronger adsorption force. At the same time, the second disc 3, as a rigid support, can better transmit force. The flat portion 22 of the first disc 2 for adhering to the second disc 3 ensures close contact between the first disc 2 and the second disc 3, allowing force to be transmitted evenly. The trapezoidal cross-section of the first disc 2 allows the edge portion of the first disc 2 to better adhere to the surface to be adsorbed, forming a tighter seal, thereby improving the firmness and reliability of adsorption.

[0035] More specifically, such as Figures 2 to 5 As shown, the bottom outer edge of the second disc 3 is provided with an annular protrusion 33, and the first disc 2 is provided with an annular groove 23 that is adapted to the annular protrusion 33. The annular protrusion 33 is connected to the annular groove 23. The annular protrusion 33 is located on the bottom outer edge of the second disc 3, and its shape and size are designed to be adapted to the annular groove 23 on the first disc 2. The annular protrusion 33 can be accurately embedded in the annular groove 23 to achieve a tight connection between the first disc 2 and the second disc 3. The design of the annular protrusion 33 and the annular groove 23 can be completed in one step during the manufacturing process, reducing assembly steps and costs. It is particularly suitable for integral molding processes such as overmolding and injection molding, improving the tightness of the connection and the structural strength.

[0036] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
