Description

Technical Field

[0001] This utility model relates to the field of dartboard technology, and in particular to a front cover for a dartboard frame. Background Technology

[0002] When using existing dartboards, a front cover is usually provided to protect the surface of the target, extend its service life, and improve its overall aesthetics. Dartboards are mostly made of cork, high-density foam, or paper composite materials. These materials are prone to wear and chipping due to repeated dart penetration, and are susceptible to dust and moisture corrosion when exposed to air for a long time, which reduces the durability of the target. The front cover can cover the edge and part of the surface of the target, effectively isolating external pollutants from direct contact with the target and reducing the impact damage to the edge of the target caused by dart penetration. Therefore, it has become an important accessory component of dartboards.

[0003] However, the front cover of the dartboard frame currently on the market is usually fixed to the target by a snap-on connection. This is achieved by setting plastic snaps on the inside of the front cover and opening corresponding slots on the edge of the target. During installation, the snaps are inserted into the slots to secure the target. Although this method is convenient, the plastic snaps themselves have low strength. Over time, the vibration generated when throwing darts will cause frequent friction between the snaps and the slots, resulting in wear on the snap surface. This gradually increases the gap between the snaps and the slots, eventually causing the front cover to loosen. In severe cases, the front cover may even fall off the target, which not only affects the accuracy of dart throwing but may also pose a safety hazard due to the front cover falling off. Utility Model Content

[0004] The purpose of this invention is to provide a front cover for a dartboard frame, which solves the problem that the current dartboard frame front covers on the market are usually fixed to the target using a snap-on connection. This method involves setting plastic snaps on the inside of the front cover and opening corresponding slots on the edge of the target. During installation, the snaps are inserted into the slots to achieve fixation. Although this method is convenient to install, the plastic snaps themselves have low material strength. Over time, the vibration generated when throwing darts will cause frequent friction between the snaps and the slots, resulting in wear on the snap surface. This gradually increases the gap between the snaps and the slots, eventually causing the front cover to loosen. In severe cases, the front cover may even fall off the target, which not only affects the accuracy of dart throwing but may also pose a safety hazard due to the front cover falling off.

[0005] To achieve the above objectives, this utility model provides a front cover for a dartboard frame, comprising a target body and a cover body. The target body has connecting mechanisms at both ends for connecting the cover body to the target body. The target body surface is provided with an installation mechanism for installing a device. The connecting mechanism includes a support block and a pressure plate. The support block and the pressure plate are both connected to one end of the target body, and the cover body is installed at the other end of the target body.

[0006] The connecting mechanism further includes a connecting ring, which is fixedly connected to one end of the cover, and the support block is fixedly connected to one end of the connecting ring.

[0007] The connecting ring is fixedly connected to a mounting frame at one end, a guide roller is slidably connected to one side of the mounting frame, the guide roller passes through one side of the mounting frame, and the pressure plate is fixedly connected to one end of the guide roller.

[0008] The mounting bracket has a threaded rod threadedly connected to one side, the threaded rod passing through one side of the mounting bracket and rotatably connected to one side of the pressure plate.

[0009] The guide roller has a limit plate fixedly connected to its other end, the threaded rod has a rotatable connection to one side of the limit plate, and a rotating block is rotatably connected to the other side of the limit plate. The rotating block is fixedly connected to the threaded rod.

[0010] A connecting plate is fixedly connected to the surface of the connecting ring, and an installation block is fixedly connected to one side of the connecting plate. A slot is opened on one side of the installation block, and a bolt is threaded to one end of the inner wall of the slot, with the bolt penetrating through one end of the inner wall of the slot.

[0011] The bolt surface is fitted with a first washer, one end of which is fixedly connected to a spring, and the other end of which is fixedly connected to a second washer, which is fitted onto the bolt surface.

[0012] This utility model relates to a front cover for a dartboard frame.

[0013] 1. In this utility model, by setting a connecting mechanism at both ends of the target body, the support block in the connecting mechanism can provide initial support for one end of the cover body, so that the cover body and the target body are initially positioned. Then, by rotating the rotating block of the mounting bracket on the connecting ring, the threaded rod is driven to rotate. The threaded engagement between the threaded rod and the mounting bracket pushes the pressure plate to move along the guide roller towards the cover body until the pressure plate is tightly attached to the surface of the cover body, so as to achieve stable pressing and fixing of the cover body and the target body. The self-locking of the threaded connection and the guiding effect of the guide roller ensure the stability and reliability of the connection.

[0014] 2. In this utility model, the mounting mechanism on the surface of the target body is fixed to the connecting plate and the connecting ring. During installation, the position of the bolt in the groove of the mounting block can be adjusted according to actual needs, and then the bolt is tightened to fix the mounting block in the designated position, thus completing the installation of the entire device. The setting of the spring, the first washer and the second washer further improves the stability of the installation and prevents the bolt from loosening. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-5This utility model provides a front cover for a dartboard frame, including a target body 1 and a cover body 4. The target body 1, as the core load-bearing component of the dartboard, not only needs sufficient structural strength to withstand the impact of the darts but also needs to provide a stable mounting foundation for the entire device. Its surface requires special treatment to accommodate the insertion and removal of darts, while ensuring structural stability after long-term use. The connecting mechanism 2 at both ends of the target body 1 is a key component for achieving precise docking and fixation between the cover body 4 and the target body 1. Through the coordinated action of multiple components, it effectively prevents the cover body 4 from shifting or loosening during long-term use, ensuring the stability of the connection. The mounting mechanism 3 on the surface of the target body 1 is responsible for installing the entire device on a wall, bracket, or other designated location. Its design must consider adaptability and convenience to meet the installation needs of different usage scenarios, further improving the flexibility of the device. The connecting mechanism 2 also includes a connecting ring 201, which is fixedly connected to one end of the cover body 4. The connecting ring 201 is made of lightweight metal, ensuring structural strength while effectively controlling the overall weight and avoiding increasing the load on the target body 1. As a transitional component connecting the cover 4 and the target 1, the annular structure of the connecting ring 201 effectively disperses the stress at the connection point, preventing damage to the component caused by local stress concentration, thereby significantly enhancing connection stability. One end of the support block 202 is welded to the connecting ring 201, while the other end is tightly fitted and fixed to the surface of the target 1. It is evenly distributed around the periphery of the connecting ring 201, further strengthening the support relationship between the connecting ring 201 and the target 1, preventing deformation or breakage at the connection point due to uneven stress. A mounting bracket 203 is also fixedly connected to one end of the connecting ring 201. The mounting bracket 203 is manufactured using an integrated molding process, resulting in a compact and stable structure, providing a reliable support frame for the subsequent installation of components such as the guide roller 204 and threaded rod 205. The mounting bracket 203 has a sliding hole on one side that matches the guide roller 204. The guide roller 204 passes through the sliding hole and is slidably connected to the mounting bracket 203. Its surface is smoothed, allowing it to move stably along the sliding trajectory of the mounting bracket 203. It plays a precise guiding role during the movement of the pressure plate 206, preventing the pressure plate 206 from shifting. The pressure plate 206 is fixedly connected to one end of the guide roller 204 by welding. A rubber gasket is attached to the side of the pressure plate 206 that contacts the target 1. This increases the friction with the surface of the target 1, improving the fixing effect, and also prevents the pressure plate 206 from scratching or damaging the surface of the target 1. As the guide roller 204 moves, the pressure plate 206 can fit tightly against the surface of the target 1, further reinforcing the connection between the cover 4 and the target 1, preventing the cover 4 from loosening during dart impacts or daily movement. The mounting bracket 203 also has a threaded hole on one side that is compatible with the threaded rod 205. The threaded rod 205 passes through the threaded hole and is threadedly connected to the mounting bracket 203. At the same time, one end of the threaded rod 205 is rotatably connected to the side of the pressure plate 206 through a bearing.When the threaded rod 205 is rotated, it moves along the axis of the threaded hole using the principle of threaded transmission, thereby pushing or pulling the pressure plate 206 to move synchronously, achieving flexible adjustment of the tightness of the connection between the cover 4 and the target 1. This adjustment method is convenient to operate, and the threaded transmission has high precision, allowing the connection tightness to be adjusted to the optimal state according to actual needs, meeting the stability requirements under different usage scenarios. The other end of the guide roller 204 is fixedly connected to a limiting plate 207. The diameter of the limiting plate 207 is larger than the diameter of the sliding hole on the mounting frame 203, which can effectively limit the sliding range of the guide roller 204, preventing it from falling off the mounting frame 203 during sliding, and ensuring the safety and stability of the component operation. The other end of the threaded rod 205 is also rotatably connected to one side of the limiting plate 207 via a bearing, and a rotating block 208 is fixedly connected to the other side of the limiting plate 207. The rotating block 208 and the threaded rod 205 are coaxially arranged. The rotating block 208 is designed as a circle with anti-slip texture, providing users with a convenient point for applying force. This allows users to easily rotate the threaded rod 205 by hand or with a wrench, reducing the difficulty of operation. At the same time, the limiting plate 207 also provides stable support for the rotation of the threaded rod 205, reducing the shaking of the threaded rod 205 during rotation and ensuring a smooth and stable adjustment process.

[0024] Please see Figures 1-5Based on the first embodiment, in this embodiment, a connecting plate 301 is fixedly connected to the surface of the connecting ring 201. The mounting mechanism 3 is based on the connecting ring 201, and the connecting plate 301 is welded to the surface of the connecting ring 201. The material of the connecting plate 301 is consistent with that of the connecting ring 201 to ensure the compatibility and structural strength of the connection between the two. Its main function is to provide a stable mounting carrier for the mounting block 302. The mounting block 302 is fixedly connected to one side of the connecting plate 301. A slot 303 is opened on one side of the mounting block 302. Its width and length can be designed according to the dimensions of common external mounting structures, which can adapt to different specifications of mounting components, significantly improving the adaptability of the device installation and meeting diverse installation needs. A threaded hole is opened at one end of the inner wall of the slot 303. A bolt 304 passes through the threaded hole and is threadedly connected to the mounting block 302. By tightening the bolt 304, the mounting block 302 can be tightly fixed to the external mounting structure, thereby realizing the installation and fixation of the entire device. On the surface of bolt 304, washers 305 and 306 are fitted, both made of elastic metal with a diameter larger than the diameter of the threaded hole in the inner wall of slot 303. Washers 305 and 306 are located on both sides of mounting block 302, increasing the contact area between bolt 304 and mounting block 302 and external mounting structure, thereby reducing local pressure and preventing deformation or damage to the mounting part due to excessive force. A spring 307 is fixedly connected between washers 305 and 306, fitting onto the surface of bolt 304, and its length in its natural state is slightly less than the distance between washers 305 and 306. Spring 307 has a good elastic buffering effect. When the device is subjected to vibration or external impact, spring 307 can absorb part of the impact force through its own extension and contraction, relieve the stress between bolt 304 and the installation part, prevent bolt 304 from loosening due to long-term vibration, ensure the stability of the installation structure, and extend the service life of the device.

[0025] Working principle: First, align the connecting ring 201 at one end of the cover 4 with both ends of the target 1, so that the support block 202 on the connecting ring 201 contacts the surface of the target 1, achieving initial support and positioning of the cover 4. Then, the operator manually rotates the rotating block 208 on one side of the limiting plate 207. The rotating block 208 drives the threaded rod 205 to rotate within the mounting frame 203. Since the threaded rod 205 is threadedly connected to the mounting frame 203, it moves along its own axis when rotating, thus pushing the pressure plate 206 towards the cover 4. During this process, the guide roller 204 at one end of the pressure plate 206 slides within the mounting frame 203, providing guidance for the movement of the pressure plate 206 and ensuring that the pressure plate 206 remains horizontal until it is tightly pressed against the surface of the cover 4. At this point, stop rotating the rotating block 208. Under the self-locking action of the threaded rod 205, the pressure plate 206 remains pressed against the cover 4, completing the connection and fixation between the cover 4 and the target 1. During the installation of the entire device, adjust the position of the bolts 304 on the mounting block 302 within the slots 303 according to the actual installation location, ensuring that the bolts 304 align with the pre-set mounting holes at the installation location. Then, tighten the bolts 304. The bolts 304 move the first washer 305 towards the mounting surface, compressing the spring 307 between the first washer 305 and the second washer 306. The spring 307 generates an elastic reaction force, causing the first washer 305 and the second washer 306 to tightly adhere to the mounting surface and the surface of the mounting block 302, respectively. This increases the friction between the bolts 304 and the mounting surface and mounting block 302, preventing the bolts 304 from loosening. After all the bolts 304 of the mounting mechanisms 3 are tightened, the entire device is installed and fixed. When disassembly and maintenance are required, rotate the rotating block 208 in the opposite direction to move the threaded rod 205 and the pressure plate 206 away from the cover 4, thereby loosening the cover 4 and facilitating maintenance of the target 1 or the cover 4; if the entire device needs to be disassembled, simply unscrew the bolt 304 on the mounting block 302, which is convenient and efficient.
