Description

Technical Field

[0001] This application relates to the technical field of sporting goods, and in particular to a dartboard mounting assembly and a dartboard. Background Technology

[0002] As a sport that combines recreation and competition, the installation and adjustment of darts-related accessories directly affect the gaming experience and safety. In particular, the installation of the dartboard directly impacts throwing accuracy and fairness. A standard dartboard is typically connected to a wall-mounted fixture via screws on its back. However, during actual installation, it often requires repeated adjustments to the screw's depth to ensure the screw head accurately engages with the connecting component and that the dartboard remains perpendicular and stable to the wall.

[0003] If the screw is not screwed in deeply enough, there will be a noticeable gap between the dartboard and the wall. This will not only cause the target to wobble and make noise during throwing, affecting the thrower's feel and scoring, but also risk the target falling off due to a weak connection. Conversely, if the screw is screwed in too deeply, the screw head will not be able to engage with the wall fastener, making installation impossible. Even if it can be hung, an excessively deep screw will concentrate stress inside the screw hole, which may damage the screw hole structure inside the dartboard over time, affecting its lifespan and even causing it to fall off. Utility Model Content

[0004] The purpose of this application is to overcome the shortcomings of the prior art and provide a dartboard mounting component and dartboard that do not require repeated debugging and have a stable connection.

[0005] The objective of this application is achieved through the following technical solution: A dartboard mounting assembly for a dartboard, wherein the dartboard body has mounting holes on its back, and comprises: A wall fastener includes a snap-fit ​​part and a connecting part. The wall fastener is connected to the wall through the connecting part. The snap-fit ​​part has a snap-fit ​​groove and a fixing groove. The snap-fit ​​groove communicates with the fixing groove. The side wall of the snap-fit ​​groove has a guide slope. The width of the opening of the snap-fit ​​groove is greater than the width of the bottom of the snap-fit ​​groove. The distance between the bottom wall of the snap-fit ​​groove and the wall gradually decreases from the opening to the fixing groove. The mounting screw includes a threaded portion, a limiting portion, and a head connected in sequence. The threaded portion is located inside the mounting hole, and the limiting portion is located between the threaded portion and the head. The snap-fit ​​groove is used to guide the limiting portion to snap into the fixing groove. The radius of the head is greater than the radius of the limiting portion, and the radius of the head gradually increases in the direction away from the limiting portion.

[0006] In one embodiment, the bottom wall of the snap-fit ​​groove is an inwardly concave arc-shaped surface.

[0007] In one embodiment, the wall fastener also forms a transition channel, the two ends of which are respectively connected to the snap-fit ​​groove and the fixing groove.

[0008] In one embodiment, the wall fastener is a one-piece molded structure.

[0009] In one embodiment, the wall fastener further includes a connector, the connector having a through hole, and the wall having a fixing hole corresponding to the through hole. The connector passes through the fixing hole and is inserted into the fixing hole to connect the wall fastener to the wall.

[0010] In one embodiment, the center of the through hole and the center of the fixing groove are on the same straight line.

[0011] In one embodiment, the dartboard mounting assembly further includes a screw sleeve disposed within the mounting hole. The inner hole of the screw sleeve has an internal thread that mates with the thread of the mounting screw, and the mounting screw is connected to the dartboard body through the screw sleeve.

[0012] In one embodiment, the outer wall of the screw sleeve facing outwards is provided with anti-slip ridges.

[0013] In one embodiment, the radius of the limiting portion is the same as the outer diameter of the threaded portion.

[0014] A dartboard includes a dartboard body and a dartboard mounting assembly as described in any of the above embodiments. The back of the dartboard body has a mounting hole, and the mounting screw of the dartboard mounting assembly is located in the mounting hole. The wall fastener of the dartboard mounting assembly is installed on a wall, and the mounting screw is engaged with the wall fastener to connect the dartboard to the wall.

[0015] In one embodiment, the dartboard includes a plurality of pads evenly distributed along the back of the dartboard body.

[0016] Compared with the prior art, this application has at least the following advantages: The aforementioned dartboard mounting assembly, by incorporating a limiting part on the mounting screw, determines the screw's screw insertion depth, allowing for successful installation without repeated adjustments and reducing installation difficulty. This avoids target wobbling caused by insufficient screw insertion depth, which could affect the throwing experience and accuracy; it also prevents issues with over-screwing, which could prevent proper engagement with wall fasteners. Furthermore, the distance between the bottom wall of the engagement groove and the wall gradually decreases from the opening towards the fixing groove, increasing the opening area of ​​the engagement groove and making it easier for the mounting screw to enter, further simplifying dartboard installation.

[0017] The dartboard mounting assembly features a guide bevel in the snap-fit ​​groove of the wall-mounted fastener. The head of the mounting screw moves downward along the guide bevel and snaps into the mounting groove. Installers do not need to align precisely; they only need to place the head of the mounting screw into the opening area to complete the mounting, thus reducing installation difficulty.

[0018] The radius of the head of the mounting screw is larger than the radius of the limiting part, and the radius of the head gradually increases in the direction away from the limiting part, forming a locking structure with the wall fixing part, which restricts the horizontal displacement and shaking of the dartboard mounting component, and avoids loosening, abnormal noise and swaying problems during use.

[0019] The distance between the bottom wall of the wall fastener's snap-fit ​​groove and the wall gradually decreases from the opening towards the fixing groove, and the width gradually narrows from the opening towards the fixing groove. That is, the snap-fit ​​groove gradually shrinks inward from the opening towards the fixing groove. When installing the dartboard, the mounting screw slides down along the snap-fit ​​groove, and the closer the dartboard is to the wall, the more stable the installation process is.

Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 6 This is a dartboard mounting assembly 10 according to an embodiment of the present invention, which includes a wall-mounted fastener 100 and mounting screws 200. The dartboard mounting assembly 10 is used for a dartboard 20, and the back of the dartboard body 21 has a mounting hole 21a. The wall-mounted fastener 100 includes a snap-fit ​​part 110 and a connecting part 120. The wall-mounted fastener 100 is connected to the wall through the connecting part 120. The snap-fit ​​part 110 has a snap-fit ​​groove 111 and a fixing groove 112. The snap-fit ​​groove 111 and the fixing groove 112 are connected. The side wall of the snap-fit ​​groove 111 forms a guide slope 1111. The width of the opening of the snap-fit ​​groove 111 is greater than the width of the bottom of the snap-fit ​​groove 111. The distance between the bottom wall of the snap-fit ​​groove 111 and the wall gradually decreases from the opening to the fixing groove 112. The mounting screw 200 includes a threaded portion 210, a limiting portion 220, and a head 230 connected in sequence. The threaded portion 210 is located in the mounting hole 21a, and the limiting portion 220 is located between the threaded portion 210 and the head 230. The snap-fit ​​groove 111 is used to guide the limiting portion 220 to snap into the fixing groove 112. The radius of the head 230 is larger than the radius of the limiting portion 220, and the radius of the head 230 gradually increases in the direction away from the limiting portion 220.

[0026] Specifically, during installation, the mounting screw 200 is screwed into the mounting hole 21a of the dartboard body 20, the wall fixing member 100 is fixed in a predetermined position on the wall, the dartboard body 20 is lifted until the mounting screw 200 is higher than the wall fixing member 100, and then the dartboard body 20 is slowly slid down so that the head 230 of the mounting screw 200 approaches the wall, while the limiting part 220 moves toward the locking groove 111. Under the guidance of the guide slope 1111, the limiting part 220 finally moves to the bottom of the fixing groove 112 so that the limiting part 220 is locked in the fixing groove 112.

[0027] In this embodiment, the dartboard mounting assembly 10 determines the screw-in depth of the mounting screw 200 by providing a limiting part 220 on the mounting screw 200, allowing for successful installation without repeated adjustments and reducing installation difficulty. This avoids target wobbling caused by insufficient screw-in depth, which could affect the throwing experience and accuracy; it also prevents the problem of failure to engage with the wall fixing component 100 due to excessive screw-in depth. Furthermore, the distance between the bottom wall of the engaging groove 111 and the wall gradually decreases from the opening towards the fixing groove 112, increasing the opening area of ​​the engaging groove 111 and making it easier for the mounting screw 200 to enter the engaging groove 111, further reducing the difficulty of dartboard installation.

[0028] Furthermore, the dartboard mounting assembly 10 incorporates a guide ramp 1111 in the snap-fit ​​groove 111 of the wall-mounted fastener 100. The head 230 of the mounting screw 200 descends along the guide ramp 1111 and snaps into the fixing groove 112. Installers do not need precise alignment; they only need to place the head 230 of the mounting screw 200 into the opening area to complete the mounting, reducing installation difficulty. In addition, the radius of the head 230 of the mounting screw 200 is larger than the radius of the limiting part 220, and the radius of the head 230 gradually increases towards the direction away from the limiting part 220, forming a locking structure with the wall-mounted fastener 100 that matches the mounting screw 200. This restricts the horizontal displacement and swaying of the dartboard mounting assembly 10, preventing loosening and abnormal noise during use.

[0029] Furthermore, the distance between the bottom wall of the snap-fit ​​groove 111 of the wall fastener 100 and the wall gradually decreases from the opening to the fixing groove 112, and the width gradually narrows from the opening to the fixing groove 112. That is, the snap-fit ​​groove 111 gradually shrinks inward from the opening to the fixing groove 112. When installing the dartboard, the mounting screw 200 slides down along the snap-fit ​​groove 111. The closer the dartboard is to the wall, the more stable the installation process is.

[0030] It should be noted that the distance between the bottom wall of the snap-fit ​​groove 111 and the wall is not limited to gradually decreasing from the opening to the fixing groove 112. For example, in other embodiments, the bottom wall of the snap-fit ​​groove 111 is a vertical plane.

[0031] like Figure 6As shown, in one embodiment, the bottom wall of the snap-fit ​​groove 111 is an inwardly concave arc-shaped surface. It is understood that the arc-shaped structure has good guiding properties, guiding the mounting screw 200 to slide smoothly and easily into the fixing groove 112, resulting in a gentler movement and improved installation experience.

[0032] It should be noted that the bottom wall of the snap-fit ​​groove 111 is not limited to the concave arc-shaped surface in the above embodiments. For example, in other embodiments, the bottom wall of the snap-fit ​​groove 111 is an inclined plane.

[0033] like Figure 1 , Figure 3 and Figure 6 As shown, in one embodiment, the wall fastener 100 also forms a transition channel 113, with its two ends connected to the snap-fit ​​groove 111 and the fixing groove 112, respectively. In this embodiment, the transition channel 113 allows the mounting screw 200 to accurately fall from the snap-fit ​​groove 111 into the fixing groove 112, extending the upper limit length in the vertical direction, preventing the mounting screw 200 from shifting during use, and improving the overall stability of the connection. Simultaneously, the downward movement of the vertical channel serves as a confirmation action that the installation is in place, reducing installation difficulty.

[0034] Furthermore, in this embodiment, the sidewall of the transition channel 113 is connected to the sidewall of the snap-fit ​​groove 111 by an arc surface. This avoids stress concentration and improves the fatigue strength and impact resistance of the wall fastener 100. At the same time, the smooth arc surface can guide the mounting screw 200 to slide smoothly into the fixing groove 112.

[0035] like Figure 6 As shown, in one embodiment, the wall fastener 100 is a one-piece molded structure. It is understood that the one-piece molding of the snap-fit ​​portion 110 and the connecting portion 120 of the wall fastener 100 enhances the overall structural strength and load-bearing stability, enabling it to resist vibrations and stresses generated by repeated impacts from darts.

[0036] like Figure 1 and Figure 6 As shown, in one embodiment, the wall fastener 100 further includes a connector 130. The wall fastener 100 is connected to the wall through the connector 130. The connecting part 120 has a through hole 1201, and the wall has a fixing hole (not shown) corresponding to the through hole 1201. The connector 130 passes through the through hole 1201 and is inserted into the fixing hole so that the wall fastener 100 is connected to the wall.

[0037] like Figure 1 and Figure 6 As shown, in one embodiment, the center of the through hole 1201 and the center of the fixing groove 112 are on the same straight line.

[0038] Specifically, in this embodiment, the wall fastener 100 has symmetrically arranged connecting portions 120 on both sides, each connecting portion 120 having a through hole 1201, and the centers of the two through holes 1201 and the center of the fixing groove 112 are on the same straight line. This ensures that during installation, the connecting member 130 generates a tightening force acting on the force center of the dartboard mounting assembly 10, avoiding eccentric loads and bending moments, thereby enhancing the overall structural strength and impact resistance, and preventing the wall fastener 100 from loosening, deforming, or the wall from being damaged. Furthermore, in this embodiment, the connecting member 130 is an expansion screw.

[0039] like Figure 4 As shown, in one embodiment, the dartboard mounting assembly 10 further includes a screw sleeve 300, which is disposed within the mounting hole 21a. The inner hole 301 of the screw sleeve 300 has an internal thread (not shown) that mates with the thread of the mounting screw. The mounting screw 200 is connected to the dartboard body 21 through the screw sleeve 300. It is understood that the screw sleeve 300 reinforces the mounting hole 21a, preventing the inner wall of the mounting hole 21a of the dartboard body 21 from being torn by the screw head, thus ensuring the stability of the connection.

[0040] like Figure 3 As shown, in one embodiment, the outer wall of the screw sleeve 300 has anti-slip textures (not shown). In this embodiment, when the screw sleeve 300 is pressed into the mounting hole 21a, the anti-slip textures engage with the dartboard body 21, preventing the screw channel from rotating during use, improving the stability of the connection between the dartboard body 21 and the screw sleeve 300, thereby ensuring the stability of the connection between the mounting screw 200 and the dartboard body 21.

[0041] like Figures 3 to 5 As shown, in one embodiment, the radius of the limiting portion 220 is the same as the outer diameter of the thread of the threaded portion 210. It is understood that having the same radius as the threaded outer diameter allows for a smooth transition between the threaded portion 210 and the limiting portion 220, avoiding stress concentration and improving fatigue resistance and long-term reliability. It also facilitates machining.

[0042] A dartboard 20 includes a dartboard body 21 and a dartboard mounting assembly 10 as described in any of the above embodiments. The dartboard body 21 has a mounting hole 21a on its back. The mounting screw of the dartboard mounting assembly 10 is located within the mounting hole 21a. A wall-mounted fastener 100 of the dartboard mounting assembly 10 is installed on a wall, and the mounting screw 200 engages with the wall-mounted fastener 100 to connect the dartboard 20 to the wall. In this embodiment, the dartboard 20 is connected to the wall via the dartboard mounting assembly 10, eliminating the need to repeatedly remove and adjust the screw depth of the mounting screw 200. Furthermore, the opening width of the locking groove 111 is greater than that of the fixing groove 112, reducing installation difficulty. Simultaneously, the locking groove 111 and the mounting screw form a locking structure, further enhancing the stability of the dartboard 20.

[0043] like Figure 2 As shown, in one embodiment, the dartboard 20 includes multiple pads 22, which are evenly distributed along the back of the dartboard body 21. It is understood that the pads 22 on the back maintain contact with the wall during installation, providing initial support, thereby reducing installation difficulty and improving efficiency. Simultaneously, the evenly distributed pads 22 work together to enhance the overall stability of the dartboard 20 after installation, effectively suppressing target tilting or shaking caused by dart impact.

[0044] Compared with the prior art, this application has at least the following advantages: The aforementioned dartboard mounting assembly, by incorporating a limiting part on the mounting screw, determines the screw's screw insertion depth, allowing for successful installation without repeated adjustments and reducing installation difficulty. This avoids target wobbling caused by insufficient screw insertion depth, which could affect the throwing experience and accuracy; it also prevents issues with over-screwing, which could prevent proper engagement with wall fasteners. Furthermore, the distance between the bottom wall of the engagement groove and the wall gradually decreases from the opening towards the fixing groove, increasing the opening area of ​​the engagement groove and making it easier for the mounting screw to enter, further simplifying dartboard installation.

[0045] The dartboard mounting assembly features a guide bevel in the snap-fit ​​groove of the wall-mounted fastener. The head of the mounting screw moves downward along the guide bevel and snaps into the mounting groove. Installers do not need to align precisely; they only need to place the head of the mounting screw into the opening area to complete the mounting, thus reducing installation difficulty.

[0046] The radius of the head of the mounting screw is larger than the radius of the limiting part, and the radius of the head gradually increases in the direction away from the limiting part, forming a locking structure with the wall fixing part, which restricts the horizontal displacement and shaking of the dartboard mounting component and avoids loosening and abnormal noise during use.

[0047] The distance between the bottom wall of the wall fastener's snap-fit ​​groove and the wall gradually decreases from the opening towards the fixing groove, and the width gradually narrows from the opening towards the fixing groove. That is, the snap-fit ​​groove gradually shrinks inward from the opening towards the fixing groove. When installing the dartboard, the mounting screw slides down along the snap-fit ​​groove, and the closer the dartboard is to the wall, the more stable the installation process is.

[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
