Description

Technical Field

[0001] This utility model belongs to the field of dartboard design and manufacturing technology, specifically relating to a wooden box dartboard that can be rotated in a fixed quantity. Background Technology

[0002] Wooden box dartboards are mainly composed of a solid wood box and a fiber target. Compared to ordinary dartboards, the addition of a box protects the fiber target inside and also increases the convenience of hanging and handling. The fiber target is made by first straightening the hemp fibers into long strips, then wrapping the strips with tape to form rolls, cutting the rolls into fiber blocks, arranging multiple blocks, compressing them to form the target surface, and finally polishing the surface, printing colors, and attaching the scoring grid. However, since most dart games use a score as the criterion for victory, the high zones of the fiber target naturally become the most frequently thrown targets. Naturally, the hit rate in the high-scoring zones and their adjacent zones is much higher than in other zones, especially as the thrower's skill improves. Therefore, after a period of use, the fiber target will experience two situations: 1. The high-scoring zones and their adjacent zones will have too many holes due to excessive dart penetration, rendering them unusable; 2. Other zones, with lower scores, will have virtually no dart penetrations and will remain in pristine condition. Consequently, the high-scoring zones of the fiber target become unusable, necessitating replacement of the target, resulting in waste and significantly shortening its lifespan. Therefore, to solve these problems, it is essential to develop a wooden box dartboard with good performance and the ability to rotate quantitatively. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wooden box dartboard with good performance and the ability to rotate quantitatively.

[0004] The purpose of this utility model is achieved as follows: A wooden box dartboard capable of quantitative rotation includes a mounting frame, a target plate, and a rotating mounting component. The mounting frame is generally square, with door panels mounted on both sides of its front end via hinges. A square back plate is fixedly installed inside the rear end, with metal mounting components fixed to both ends of its upper surface by screws. A through hole is provided in the center of the square back plate. The target plate is located at the front end of the square back plate and is concentrically positioned with the through hole. The rotating mounting component is located at the rear end of the square back plate and includes a fixing ring, an elastic sheet, a rotating block, and a mounting plate. The fixing ring is concentrically fixed to the rear end of the square back plate by fixing bolts, and an annular placement groove is provided in the middle of the outer end face of the fixing ring. A notch is formed between the inner wall of the upper end of the placement groove and the annular inner surface of the fixing ring. The elastic sheet is made of metal. The overall shape is V-shaped, horizontally clamped into the upper part of the placement groove, and a limiting post is connected below the elastic sheet. The limiting post slides vertically through the notch. The rotating block is circular and rotates inside the fixed ring. A square connecting groove is opened at the center of the rotating block. Multiple limiting grooves that cooperate with the limiting post structure are evenly opened on the outer surface. A retaining ring is concentrically fixed to the rear end face. The outer diameter of the retaining ring is larger than the inner diameter of the fixed ring. A slot is opened in the inner wall of the connecting groove. The mounting plate is square and placed in the connecting groove. A protrusion that cooperates with the slot structure is fixed on the outer side of the mounting plate. Multiple connecting screw holes are opened in the middle position. A limiting bolt passes through each connecting screw hole. One end of the limiting bolt is located on the outside of the mounting plate, and the other end passes through the connecting screw hole and the through hole in sequence, and is limited and connected to the rear end face of the target plate.

[0005] Furthermore, the metal mounting component is provided with vertical mounting holes.

[0006] Furthermore, the lower end of the limiting post has a semi-circular structure.

[0007] Furthermore, the elastic sheet and the limiting post are integrally connected.

[0008] Furthermore, the outer surface of the rotating block is uniformly provided with ten limiting grooves that cooperate with the limiting post structure, and the limiting grooves are arc-shaped as a whole.

[0009] The beneficial effects of this utility model are as follows: By setting up a hanging frame and a box door, the target plate can be placed and protected at the same time by using the cooperation of the hanging frame and the box door. By setting up metal hanging parts and hanging holes, the entire utility model can be easily hung on the wall.

[0010] By setting up a fixed ring, rotating block, retaining ring, slot, protrusion, and mounting plate, and utilizing the fixed connection between the fixed ring and the square back plate, the fixed connection between the mounting plate and the target plate, the limiting installation achieved by the slot and protrusion between the mounting plate and the rotating block, and the lateral limiting effect of the retaining ring on the rotating block, the target plate can be installed inside the mounting frame while simultaneously being rotated by external force through the rotating connection between the rotating block and the fixed ring. This rotation of the target plate allows for the rotation of the scoring zones on its surface. Furthermore, by using the rotation of the scoring zones in conjunction with the digital disc subsequently installed on the target plate surface, the high zone position on the target plate surface can be redefined. This solves the problem of existing target plates having too many dart holes in the high zone due to excessive dart penetrations, rendering them unusable, and increases their service life.

[0011] Meanwhile, through the arrangement of elastic plates, limiting posts, notches, and limiting grooves, during the rotation of the target disk, which in turn drives the mounting plate and rotating block to rotate, the elasticity of the elastic plates, combined with the vertical sliding connection between the limiting posts and the notches, allows the limiting posts to disengage from the current limiting groove. Simultaneously, as the rotating block continues to rotate, the limiting posts reconnect with the next limiting groove. This structure enables precise rotation of the rotating block and the target disk, thereby increasing the accuracy of the target disk rotation angle and the rotation adjustment of the scoring zones. In summary, this invention offers the advantages of precise and convenient rotation adjustment operation and excellent performance. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a wooden box dartboard capable of quantitative rotation includes a mounting frame 1, a target plate 2, and a rotating mounting component 3. The mounting frame 1 is generally square, with door 11 hinged to both sides of its front end. A square back plate 12 is fixedly installed inside the rear end, with metal mounting components 13 fixed to both ends of its upper surface by screws. A through hole is provided in the center of the square back plate 12. The target plate 2 is located at the front end of the square back plate 12 and is concentrically arranged with the through hole. The rotating mounting component 3 is located at the rear end of the square back plate 12 and includes a fixing ring 31, an elastic piece 32, a rotating block 33, and a mounting plate 34. The fixing ring 31 is concentrically fixed to the rear end of the square back plate 12 by fixing bolts, and an annular placement groove 311 is provided in the middle of the outer end face of the fixing ring 31. A notch 312 is provided between the inner wall of the upper end of the placement groove 311 and the annular inner surface of the fixing ring 31. The elastic piece 32 is made of metal and is V-shaped, laterally clamped into the placement groove 31. 1. An inner upper end, and a limiting post 35 connected below the elastic sheet 32, the limiting post 35 is vertically slidably inserted into the notch 312. The rotating block 33 is generally circular and is rotatably placed inside the fixed ring 31. A square connecting groove 331 is opened at the center of the rotating block 33. Multiple limiting grooves 332 that cooperate with the structure of the limiting post 35 are evenly opened on the outer surface. A retaining ring 333 is concentrically fixed to the rear end face. The outer diameter of the retaining ring 333 is larger than the inner diameter of the fixed ring 31. The inner wall of the connecting groove 331 is provided with a slot 334. The mounting plate 34 is generally square and is placed in the connecting groove 331. The outer side of the mounting plate 34 is fixedly provided with a protrusion 341 that matches the structure of the slot 334. Multiple connecting screw holes 342 are provided in the middle position. Each connecting screw hole 342 is provided with a limiting bolt. One end of the limiting bolt is located on the outside of the mounting plate 34, and the other end passes through the connecting screw hole 342 and the through hole in sequence, and is limited and connected to the rear end face of the target plate 2.

[0022] The metal mounting component 13 is vertically provided with mounting holes 14, which can increase the convenience of mounting operation of this utility model; the elastic sheet 32 ​​and the limiting post 35 are integrally connected; the lower end of the limiting post 35 has a semi-circular structure, and the outer surface of the rotating block 33 is evenly provided with ten limiting grooves 332 that cooperate with the structure of the limiting post 35, and the limiting grooves 332 are arc-shaped as a whole. This structure can increase the smoothness of the connection between the limiting post 35 and the limiting grooves 332 when the rotating block 33 rotates.

[0023] In use, this utility model utilizes the fixed connection between the fixing ring 31 and the square back plate 12 through fixing bolts, the fixed connection between the mounting plate 34 and the target plate 2 through limiting bolts, the limiting installation between the mounting plate 34 and the rotating block 33 through the slot 334 and the protrusion 341, and the lateral limiting effect of the retaining ring 333 on the rotating block 33, to achieve the installation of the target plate 2 inside the hanging frame 1. Thus, by utilizing the cooperation between the hanging frame 1 and the box door 11, the target plate 2 can be protected, and the metal hanging parts 13 and hanging holes 14 at the upper end of the hanging frame 1 can be used to achieve the overall hanging placement of this utility model on the wall.

[0024] With prolonged use of this invention, when the high-section area on the surface of the target disk 2 becomes unusable due to excessive dart penetration, resulting in a large number of dart holes, an external force can be applied to the surface of the target disk 2. This external force, combined with the rotating engagement between the rotating block 33 and the fixed ring 31, allows for the adjustment of the target disk 2's rotation. This rotation of the target disk 2 then rotates the scoring section on its surface. Furthermore, the rotation of the scoring section, along with the subsequent positioning of the digital disc on the surface of the target disk 2, allows for the re-determination of the high-section position on the target disk 2. Simultaneously, the elastic sheet 32, the limiting post 35, the notch 312, and the limiting groove 332 ensure proper positioning of the target disk. During the rotation of the 2nd component, which causes the mounting plate 34 and the rotating block 33 to rotate, the elasticity of the elastic sheet 32, combined with the vertical sliding connection between the limiting post 35 and the notch 312, allows the limiting post 35 to disengage from the current limiting groove 332. As the rotating block 33 continues to rotate, the limiting post 35 is reconnected to the next limiting groove 332. This invention, using this structure, can achieve a quantitative rotation of the rotating block 33 and the target disk 2 through the cooperation of the limiting post 35 and the limiting groove 332, thereby increasing the accuracy of the rotation angle of the target disk 2 and the rotation adjustment of the scoring area. In summary, this invention has the advantages of precise and convenient rotation adjustment operation and good performance.
