Description

Technical Field

[0001] This utility model relates to the field of dartboard technology, and in particular to a portable foldable dartboard. Background Technology

[0002] As a core piece of equipment in darts, the dartboard is a crucial tool for players to throw darts, score, and enjoy entertainment. Its structural design and ease of use directly impact the gaming experience, adaptability to different playing surfaces, and portability. In applications such as home entertainment, professional training, and leisure venues, the dartboard is an indispensable component, and its installation method, storage configuration, and ease of movement significantly influence user efficiency and space utilization. Particularly in the daily use aspect of storage and portability, existing dartboards, with their large space requirements and fixed shapes, are gradually revealing a series of significant limitations and technical problems.

[0003] Utility model patent CN204666046U discloses a dartboard, including a dartboard body and a connector. One side of the connector has a locking element, and the other side is a smooth plane with double-sided adhesive. The side of the dartboard body adjacent to the connector has a locking position. A positioning hole corresponding to the center circle of the dartboard body is formed at the center of the connector. The double-sided adhesive is adhered to the smooth wall surface, and the locking position engages with it. This technical solution achieves the fixation of the dartboard to a smooth wall surface using double-sided adhesive, avoiding damage to the wall surface caused by screws or angle irons. Simultaneously, the positioning hole enables quick and accurate setting of the dartboard height.

[0004] However, despite improvements in installation, existing dartboards generally have a fixed structure that makes them difficult to fold. This rigid structure results in a large overall size, occupying significant storage space when not in use and severely limiting the flexibility and practicality of darts. Therefore, to address the shortcomings of existing dartboards—such as difficulty in folding, large size, and inconvenience in carrying and storing—we urgently need an innovative portable foldable dartboard to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a portable foldable dartboard, which solves the problem that existing dartboards generally have a fixed structure, making them inconvenient to fold. This rigid structure results in a large overall size of the dartboard, which occupies a lot of storage space when not in use, greatly limiting the flexibility and practicality of darts.

[0006] To achieve the above objectives, this utility model provides a portable foldable dartboard, including a support tube, and a plurality of support grooves are formed on the outer wall of the support tube, and a fan-shaped plate is provided on one side of all the support grooves;

[0007] One end of each sector plate is rotatably connected to the inner wall of each of the bearing grooves. Each pair of adjacent sector plates is fixedly connected with a folding strap. One side of each sector plate is fixedly connected with a fixing plate by bolts. Each fixing plate has a support rod at its bottom, and an adsorption plate is fixedly connected to the bottom of each support rod. The top of each support rod passes through each fixing plate and is elastically connected to the top of each fixing plate. The bottom of the bearing tube is connected to a suction cup, and a piston is provided inside the bearing tube. The bottom of the bearing tube is provided with a receiving tube.

[0008] The top of the bearing tube is fixedly connected to a top plate, and the top of the piston is rotatably connected to a threaded rod via a rotating shaft, with the top end of the threaded rod penetrating the top plate through a threaded groove.

[0009] The outer walls of the storage tube are fixedly connected to handles on both sides.

[0010] The storage tube has shoulder straps on both sides, and each end of the two shoulder straps is fixedly connected to a connecting block. One side of each of the four connecting blocks is fixedly connected to the outer wall of the storage tube.

[0011] All the support rods have a tension spring fitted on one end, and the top of the support rod is elastically connected to the top of the fixed plate through the tension spring.

[0012] In this configuration, one end of each sector plate is rotatably connected to the inner wall of each bearing groove via a pin.

[0013] This utility model discloses a portable foldable dartboard. By setting multiple support grooves on the outer wall of the support tube and rotatably connecting them with fan-shaped plates, combined with folding straps connecting adjacent fan-shaped plates, the main body of the dartboard can be folded. This solves the problems of fixed structure, large size, difficulty in storage, and inconvenience in carrying existing dartboards. When not in use, the dartboard can be folded into a long, thin cylinder, significantly reducing its overall space occupation. This makes it convenient for users to store or carry it in the storage tube, greatly improving the device's portability and space adaptability, and meeting the flexible use needs of various scenarios such as home, travel, and outdoor activities. By setting a suction cup at the bottom of the support tube, and using a vacuum enhancement mechanism consisting of an internal piston and a rotatable threaded rod, users can easily lift the piston by rotating it. The internal negative pressure creates a stronger and more durable suction effect than ordinary suction cups, effectively preventing the dartboard from falling off due to insufficient suction during use, thus improving the reliability and safety of installation. An auxiliary fixing mechanism consisting of a fixing plate, support rod, and suction plate is installed on one side of each unfolded fan-shaped plate. The top of the support rod is elastically connected to the fixing plate, allowing the suction plate to be pressed down and adhered to the wall, providing additional support points for the edge of the target surface. This effectively resists the impact force generated during dart throwing and the weight of the fan-shaped plate itself, preventing target surface deformation, shaking, or edge sagging. This significantly improves the structural stability and flatness of the entire dartboard in use, ensuring the accuracy of throwing and scoring. The storage tube not only provides space for storing the folded target but also protects the target surface and facilitates carrying. Attached Figure Description

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 .

[0023] A portable foldable dartboard includes a support tube 1, and a plurality of support grooves 2 are provided on the outer wall of the support tube 1, and a fan-shaped plate 3 is provided on one side of all the support grooves 2.

[0024] One end of each of the sector plates 3 is rotatably connected to the inner wall of each of the bearing grooves 2. Each pair of adjacent sector plates 3 is fixedly connected with a folding strap 12. One side of each sector plate 3 is fixedly connected with a fixing plate 5 by bolts. Each fixing plate 5 has a support rod 4 at its bottom. Each support rod 4 has an adsorption plate 7 fixedly connected to its bottom end. The top of each support rod 4 passes through each fixing plate 5. The top of each support rod 4 is elastically connected to the top of each fixing plate 5. The bottom of the bearing tube 1 is connected to a suction cup 15. The inner side of the bearing tube 1 is provided with a piston 16. The bottom of the bearing tube 1 is provided with a receiving tube 8.

[0025] When storage or carrying is required, firstly, all the fan-shaped plates 3 are rotated and folded towards the support tube 1 around the rotating connection point between them and the support groove 2 on the outer wall of the support tube 1. Adjacent fan-shaped plates 3 are flexibly connected by a fixed folding strap 12. The folding strap 12 retracts during the folding process, and all the fan-shaped plates 3 are finally tightly attached to the outer wall of the support tube 1, forming a compact cylindrical structure. Then, this folded overall structure is pushed into the storage tube 8 for storage and protection, making it easy to carry and saving space. When the dartboard needs to be used, the folded target is taken out of the storage tube 8, and all the fan-shaped plates 3 are unfolded outward from the support tube 1 to form a complete circular target surface around the support tube 1. After unfolding, the suction cup 15 at the bottom of the support tube 1 is pressed against a flat wall or other vertical support surface to make the suction cup 15 initially adhere to the wall surface. Then, by rotating the threaded rod 14 at the bottom of the support tube 1, the rotation of the threaded rod 14 drives the movable part on its inner side. The plug 16 is pulled upwards inside the bearing tube 1, thereby creating negative pressure inside the suction cup 15, enhancing the adhesion and stability between the suction cup 15 and the wall, and completing the initial fixation of the dartboard body. Subsequently, the support rod 4 on the fixing plate 5, which is fixed to one side of each fan-shaped plate 3 by bolts, is pressed downwards. The top of the support rod 4 passes through the fixing plate 5 and is elastically connected to the top of the fixing plate 5 by an elastic element. When the support rod 4 is pressed down, the suction plate 7 at its bottom contacts and adheres to the wall. The adhesion between the suction plate 7 and the wall provides additional support and fixation for the edge of the unfolded fan-shaped plate 3, preventing it from shaking or sagging due to the impact of dart throwing or its own weight, thereby further improving the stability and flatness of the entire dartboard installation. The entire installation process does not require any external fixing tools, and the operation is simple and quick. Disassembly is done by reversing the operation. The suction plate 7 is removed from the wall, the negative pressure inside the suction cup 15 is released, and the entire device can be easily removed and folded for storage.

[0026] Furthermore, a top plate 13 is fixedly connected to the top of the support tube 1, and a threaded rod 14 is rotatably connected to the top of the piston 16 via a rotating shaft. The top end of the threaded rod 14 passes through the top plate 13 via a threaded groove. When it is necessary to enhance the suction force of the suction cup 15, the threaded rod 14 is rotated. The threaded rod 14 rotates and moves upward within the threaded groove of the top plate 13, driving the piston 16 to move upward within the support tube 1 via the rotating shaft. The top plate 13 provides stable support and a precise axis of rotation for the threaded rod 14. The rotating shaft connection allows the threaded rod 14 to adapt to the linear motion of the piston 16 during rotation, achieving the effect of smoothly and reliably converting the rotational motion into the linear motion of the piston 16. This ensures that the piston 16 can effectively draw air from inside the suction cup 15 to form a negative pressure, enhancing the adhesion tightness and stability of the suction cup 15 to the wall. At the same time, this structure is compact and easy to operate.

[0027] Furthermore, handles 10 are fixedly connected to both sides of the outer wall of the storage tube 8. When carrying the stored dartboard, the user can directly hold the handles 10 on both sides for carrying, which achieves the effect of providing a convenient, comfortable and labor-saving grip, making it convenient for the user to operate when moving short distances or taking it out from the storage position, thus improving the convenience of carrying and ergonomic comfort.

[0028] Furthermore, both sides of the storage tube 8 are equipped with shoulder straps 9, and each end of the two shoulder straps 9 is fixedly connected with a connecting block 11. One side of each of the four connecting blocks 11 is fixedly connected to the outer wall of the storage tube 8. Users can carry the shoulder straps 9 over their shoulders. The connecting blocks 11 ensure the firm connection between the shoulder straps 9 and the storage tube 8, achieving the effect of carrying the dartboard in the form of a backpack for long distances or when both hands need to be free. This greatly expands the portability of the device and makes it easier to transport it between different locations.

[0029] Furthermore, a tension spring 6 is fitted on one end of each of the support rods 4, and the top of the support rod 4 is elastically connected to the top of the fixing plate 5 through the tension spring 6. When the support rod 4 is pressed down to make the adsorption plate 7 contact the wall, the tension spring 6 is stretched and stores elastic potential energy. After the adsorption plate 7 is adsorbed and fixed, the tension of the tension spring 6 continues to act, ensuring that the adsorption plate 7 at the bottom of the support rod 4 is firmly pulled to the wall and maintains a tight adsorption state. Even if the wall is slightly uneven or subjected to slight vibration, the tension spring 6 can provide a continuous pre-tightening force to compensate, achieving a more firm and reliable adsorption of the adsorption plate 7 to the wall, effectively preventing loosening or falling off due to insufficient adsorption force, and improving the stability and durability of the auxiliary fixing mechanism.

[0030] Furthermore, one end of each of the sector plates 3 is rotatably connected to the inner wall of each of the bearing grooves 2 via pins.

[0031] In summary:

[0032] When storage or carrying is required, all fan-shaped plates 3 are first rotated and folded towards the support tube 1 around the rotation connection point between them and the support groove 2 on the outer wall of the support tube 1. Adjacent fan-shaped plates 3 are flexibly connected by a fixed folding strap 12, which retracts during the folding process. All fan-shaped plates 3 are finally tightly fitted to the outer wall of the support tube 1, forming a compact cylindrical structure. This folded structure is then pushed into the storage tube 8 for storage and protection. The handles 10 fixed on both sides of the outer wall of the storage tube 8 facilitate carrying by the user, and the shoulder straps 9 on both sides allow for easy carrying. The connecting block 11 at the end is firmly connected to the outer wall of the storage tube 8, allowing users to carry it by hand or over their shoulder for easy transport and space saving. When the dartboard needs to be used, the folded target is taken out of the storage tube 8, and all the fan-shaped plates 3 are unfolded outward from the support tube 1 to form a complete circular target surface around the support tube 1. After unfolding, the suction cup 15 at the bottom of the support tube 1 is pressed against a flat wall or other vertical support surface to make the suction cup 15 initially adhere to the wall. Then, by rotating the threaded rod 14 at the bottom of the support tube 1, the top of the threaded rod 14 passes through the support tube through the threaded groove. 1. The top plate 13 is fixed at the top. When rotated, the threaded rod 14 moves upward in the threaded groove of the top plate 13. Its bottom end drives the piston 16 to pull upward in the bearing tube 1 through the rotating shaft, thereby forming a negative pressure inside the suction cup 15, enhancing the adhesion and stability between the suction cup 15 and the wall, and completing the initial fixation of the dartboard body; then, the support rod 4 on the fixed plate 5, which is fixed to one side of each sector plate 3 by bolts, is pressed down. The top end of the support rod 4 penetrates the fixed plate 5, and the tension spring 6 sleeved at one end is stretched. When the suction plate 7 at the bottom end of the support rod 4 contacts and adheres to the wall, the tension spring... The continuous elastic pull of the 6 rod firmly pulls the support rod 4 and the suction plate 7 against the wall, maintaining a tight adhesion. The adhesion between the suction plate 7 and the wall provides additional support and fixation to the edge of the unfolded fan-shaped plate 3, preventing it from shaking or sagging due to the impact of the dart throwing or its own weight. This further improves the stability and flatness of the entire dartboard installation. The entire installation process requires no external fixing tools and is simple and quick to operate. Disassembly is done by reversing the operation. Simply remove the suction plate 7 from the wall, release the negative pressure inside the suction cup 15, and the entire device can be easily removed and folded back for storage.By setting multiple support grooves 2 on the outer wall of the support tube 1 and rotatably connecting them to the fan-shaped plates 3, combined with the folding straps 12 connecting adjacent fan-shaped plates 3, the foldable function of the main structure of the dartboard is realized. This solves the problems of fixed structure, large size, difficulty in storage and inconvenience in carrying dartboards in the existing technology. It allows the dartboard to be folded into a long and thin cylindrical shape when not in use, significantly reducing the overall space occupied. This makes it convenient for users to put it into the storage tube 8 for storage or carrying, greatly improving the portability and space adaptability of the device, and meeting the flexible use needs of various scenarios such as home, travel, and outdoor activities. By setting a suction cup 15 at the bottom of the support tube 1, and cooperating with the vacuum enhancement mechanism consisting of an internal piston 16 and a rotatable threaded rod 14, users can lift the piston 16 by simple rotation, forming a stronger negative pressure in the suction cup 15, thereby obtaining a stronger and more durable adsorption effect than ordinary suction cups 15. This effectively prevents the dartboard from falling off due to insufficient adsorption force during use, improving the reliability and safety of installation. By setting a fixed plate 5, a support rod 4 and an adsorption strap on one side of each unfolded fan-shaped plate 3, the dartboard can achieve a foldable function. The auxiliary fixing mechanism consisting of plates 7 has the top of the support rod 4 elastically connected to the top of the fixing plate 5 via a sleeved tension spring 6. This ensures that the adsorption plate 7 is continuously subjected to downward tension after adsorption, guaranteeing the firmness and reliability of the adsorption. It effectively resists the impact force generated during dart throwing and the weight of the fan-shaped plate 3 itself, preventing the target surface from deforming, shaking, or sagging at the edges. This significantly improves the structural stability and flatness of the entire dartboard in use, ensuring the accuracy of throwing and scoring. The storage tube 8 not only provides space for storing the folded target but also serves to protect it. The protective surface serves a purpose, with handles 10 fixed on both sides of its outer wall providing a convenient way to hold it. The shoulder straps 9 on both sides are firmly connected by connecting blocks 11, allowing users to carry the device over long distances on their shoulders, greatly expanding its portability. The top plate 13 fixed to the top of the support tube 1 provides stable support and precise rotation guidance for the threaded rod 14. The pivot connection between the piston 16 and the threaded rod 14 ensures the smoothness of motion transition. All the sector plates 3 are rotatably connected to the support groove 2 through pins, ensuring the flexibility and reliability of folding and unfolding.
