Description

Technical Field

[0001] The utility model relates to the technical field of outdoor sporting goods, in particular to a dual-purpose magnetic base for a compound bow. Background Art

[0002] With the development of science and technology and the improvement of people's demands, bows have gradually become modernized. As a type of modern bow, compound bows can both shoot arrows and fire steel balls. They are more flexible to use and have more usage scenarios. Therefore, they are favored by consumers.

[0003] Currently, dual-purpose magnetic mounts for compound bows on the market can hold both arrows and steel balls, meeting dual-purpose requirements. For example, patent CN220670324U discloses a steel ball mount for bows and arrows (actually the aforementioned dual-purpose magnetic mount). The mount features a central channel for inserting and securing the shear tail. A magnetic block for attracting the steel ball is mounted on the mount body. One end of the channel engages the steel ball, while the other end houses a magnetic block. This magnetic block attracts the steel ball, ensuring a stable hit on target during shooting. Furthermore, the magnetic block is secured within the channel by an external expansion and tightening structure. The magnetic block is a strong magnetic ring, and the external expansion and tightening structure is a retaining spring structure that secures the magnetic block within the channel. Although the above structure can realize the installation of arrows and steel balls, the structure inside it that attracts the steel balls is a strong magnetic ring. Therefore, it is necessary to ensure the stability of the installation of the strong magnetic ring, resulting in a support step being provided on the steel ball seat body and at one end of the fixed channel that cooperates with the steel ball, and the diameter of the fixed channel must be larger than the outer diameter of the strong magnetic ring and is a through-hole structure. In order to adapt to the size of the steel ball, the size of the strong magnetic ring should not be too small, so the size of the fixed channel is also larger. However, the steel ball seat body itself is small in size. After a larger fixed channel is set on it, the structural strength of the steel ball seat body is poor and it is easy to break, affecting the service life and safety of the steel ball seat. In addition, if a part of the strong magnetic ring is damaged, the entire area needs to be replaced, and the cost of use is also high.

[0004] In summary, the existing dual-purpose magnetic base for compound bows has problems such as poor structural strength, short service life, potential safety hazards in use, and high cost of use. Summary of the Invention

[0005] In response to the above-mentioned problems existing in the prior art, the present invention aims to provide a dual-purpose magnetic base for a compound bow, in which a plurality of embedding holes are opened on the outside of the socket of the magnetic base body, and a magnet is embedded in each embedding hole. In addition, a coaxially arranged steel ball placement hole is provided at the hole mouth of one end of the socket, and the steel ball placement hole is connected to the socket. One end of the magnet extends to the connection between the socket and the steel ball placement hole. The arrow is installed through the socket, and the steel ball is installed through the steel ball placement hole, which meets the dual-purpose requirements. At the same time, the magnet is installed through the embedding hole, and the adjacent embedding holes are arranged at intervals, which avoids the problem of insufficient structural strength of the magnetic base body caused by directly expanding the socket, extends the service life, and improves the safety of use. At the same time, after some magnets are damaged, only the corresponding magnets need to be replaced, and there is no need to replace all magnets, which reduces the cost of use.

[0013] In the above-mentioned dual-purpose magnetic base for a compound bow, a chamfer is provided on the opening at the connection between the insertion hole and the steel ball placement hole.

[0014] The above-mentioned dual-purpose magnetic base for a compound bow has rope mounting parts symmetrically arranged on the upper and lower sides of the magnetic base body, each rope mounting part is provided with a rope threading hole, and the two ends of the rope are respectively connected to the rope threading holes on the two rope mounting parts.

[0015] The above-mentioned dual-purpose magnetic base for a compound bow, wherein extension parts are provided at both ends of the pressure plate, and the two extension parts correspond one-to-one to the two pull rope mounting parts respectively.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To the attached Figure 4 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0027] Figure 1 This is a structural diagram of an embodiment of a dual-purpose magnetic base for a compound bow of the present invention. Figure 1 As shown, the dual-purpose magnetic base for a compound bow provided in this embodiment includes: a magnetic base body 1 and a pressure plate 3, and the pressure plate 3 is attached to one side of the magnetic base body 1.

[0028] Figure 2 This is a structural diagram of the magnetic base body from one perspective of a dual-purpose magnetic base for a compound bow according to the present invention; Figure 3 This is a structural diagram of the magnetic base body of a compound bow dual-purpose magnetic base of the utility model from another perspective. Figures 1 to 3As shown, the magnetic base body 1 is a square block. In this case, a socket 11 is opened in the center of the magnetic base body 1 and runs through its two end surfaces. This provides conditions for the subsequent insertion of the arrow tail into the magnetic base body 1, meeting the use requirements of launching arrows. At the same time, a coaxially arranged steel ball placement hole 12 is provided on the magnetic base body 1 and located at one end of the hole 11. The steel ball placement hole 12 and the hole 11 are interconnected. That is, when installing an arrow, the arrow tail is inserted into the hole 11 through the steel ball placement hole 12. When installing a steel ball, the steel ball can be directly placed in the steel ball placement hole 12, realizing the dual purpose of the magnetic base. In addition, a plurality of embedded holes 13 are provided on the magnetic base body 1 and located outside the socket 11, and are arranged in the same direction as the socket 11. A gap is provided between adjacent embedded holes 13. At the same time, a gap is also provided between the embedded holes 13 and the socket 11, so that there is material between the socket 11 and the embedded holes 13 for support. In addition, it can also avoid the problem that the inner diameter of the socket 11 is expanded due to the need to install a large strong magnetic ring, resulting in the smaller magnetic base body 1 being hollowed out and its structural strength being reduced, thereby ensuring the structural strength of the magnetic base body 1, extending the service life, and ensuring safety in use. In addition, one end of the embedded hole 13 is extended to the connection between the socket 11 and the steel ball placement hole 12, and a magnet 2 is embedded in each embedded hole 13. The embedded hole 13 provides space for the installation of the magnet 2 on the magnetic base body 1, and also allows the magnet 2 in the embedded hole 13 to extend to the connection between the socket 11 and the steel ball placement hole 12, providing conditions for the subsequent magnet 2 to attract the steel ball placed in the steel ball placement hole 12. In addition, the magnets 2 can be arranged in a plurality and spaced apart from each other. Compared with the existing strong magnetic rings arranged as a whole, the magnets 2 can be dispersed, so that when some magnets 2 are damaged, the damaged magnets 2 can be replaced individually, avoiding the problem of replacing the strong magnetic ring as a whole and reducing the cost of use.

[0029] Figure 4 This is a structural diagram of the pressure plate of a dual-purpose magnetic base of a compound bow of the present invention. Figure 1 and Figure 4 As shown, the pressure plate 3 is set at the end of the magnetic base body 1 away from the steel ball placement hole 12. At this time, one side of the pressure plate 3 presses the end of the magnet 2 away from the steel ball placement hole 12, that is, the pressure plate 3 is attached to the end of the magnetic base body 1. Since the magnet 2 is embedded in the embedding hole 13, the end of the embedding hole 13 away from the steel ball placement hole 12 is directly open. In order to prevent the magnet 2 in the embedding hole 13 from escaping from the end away from the steel ball placement hole 12, the hole 13 is covered by the pressure plate 3. In addition, the pressure plate 3 can cover the openings of all the embedding holes 13 at the same time, which improves the integrity and makes disassembly and assembly more convenient. In addition, the pressure plate 3 is also provided with an avoidance hole 31 corresponding to the socket 11, ensuring that the two ends of the socket 11 can be connected to the outside world through the steel ball placement hole 12 and the avoidance hole 31 respectively, ensuring that the tail of the arrow can be smoothly installed on the magnetic base body 1.

[0030] Specifically, a plurality of embedded holes 13 are distributed in a circular array on the outside of the insertion hole 11 with the axis of the insertion hole 11 as the axis center, so that a plurality of embedded holes 13 are arranged in a circular manner and are evenly distributed on the outside of the insertion hole 11, so that when the magnet 2 in the subsequent embedded hole 13 absorbs the steel ball in the steel ball placement hole 12, the steel ball can be subjected to uniform force. At the same time, the weight distribution of the magnetic base body 1 can also be more uniform, thereby improving the stability of the magnetic base during use.

[0031] More specifically, the diameter of the steel ball placement hole 12 at the connection between the steel ball placement hole 12 and the insertion hole 11 is larger than the diameter of the insertion hole 11, so that a step 14 can be formed at the connection between the steel ball placement hole 12 and the insertion hole 11. Preferably, the embedded hole 13 is extended to one end of the connection between the insertion hole 11 and the steel ball placement hole 12 and is flush with the surface of the step 14, so that one end of the magnet 2 in the embedded hole 13 can be extended to a state flush with the surface of the step 14, so that the magnet 2 can be closer to the steel ball placement hole 12 and better absorb the steel balls in the steel ball placement hole 12.

[0032] More specifically, one side of one end of each embedded hole 13 aligned with the surface of the step 14 passes through the surface of the step 14, and the other side of each embedded hole 13 is covered by the material forming the hole wall of the steel ball placement hole 12. When the magnet 2 is installed in the embedded hole 13, only one side of the end of the magnet 2 in the embedded hole 13 is exposed at the connection between the steel ball placement hole 12 and the socket 11, and the other side of the end of the magnet 2 is covered to limit the magnet 2, which can not only make the magnet 2 directly contact the steel ball in the steel ball placement hole, but also avoid the magnet 2 from escaping from the hole at one end of the embedded hole 13 passing through the surface of the step 14, so the structural reliability is higher. In addition, it can also achieve covering of the embedded hole 13 and part of the magnet 2, thereby improving the hiding effect and improving the overall aesthetics.

[0033] More specifically, a chamfer 15 is provided on the edge of the opening at the connection between the insertion hole 11 and the steel ball placement hole 12. The chamfer 15 forms a flared structure at the connection between the insertion hole 11 and the steel ball placement hole 12. The flared structure serves as an auxiliary steel ball hole. That is, when a smaller steel ball cannot fit better in the hole wall of the steel ball placement hole 12, the steel ball can be placed through the auxiliary steel ball hole. This allows the magnetic base to adapt to the launch requirements of steel balls of different sizes and maintain stability during launch. In addition, the arrangement of the chamfer 15 can also provide guidance for the arrow's tail when it is inserted into the insertion hole 11, meeting the use requirements of quick and accurate insertion into the insertion hole 11, and the structural design is more reasonable.

[0034] More specifically, rope mounting portions 16 are symmetrically provided on the upper and lower sides of the magnetic base body 1, and a rope threading hole 161 is provided on each rope mounting portion 16. During assembly, the two ends of the rope 4 are respectively connected to the rope threading holes 161 on the two rope mounting portions 16, that is, the rope threading holes 161 facilitate the connection of the rope 4 to the rope mounting portion 16 on the magnetic base body 1.

[0035] More specifically, extensions 32 are provided at both ends of the pressure plate 3. When the pressure plate 3 is mounted on one end of the magnetic base body 1, the two extensions 32 on the pressure plate 3 correspond one-to-one with the two rope mounting portions 16 on the magnetic base body 1. Furthermore, an auxiliary through-hole 321 is provided on each extension 32. When the pressure plate 3 is mounted on one end of the magnetic base body 1, the auxiliary through-hole 321 corresponds one-to-one with the rope threading hole 161. Furthermore, the rope ends of the ropes 4 corresponding to the rope threading holes 161 are simultaneously tied to the auxiliary through-holes 321, so that the pressure plate 3 and the magnetic base body 1 can be tied together by the ropes 4. This facilitates the stable installation of the pressure plate 3 on the magnetic base body 1. Furthermore, there is no need to provide additional screw holes or other structures on the pressure plate 3, thus avoiding damage to the structures of the pressure plate 3 and the magnetic base body 1, and the structural design is more reasonable.

[0036] More specifically, string-binding parts 17 are symmetrically arranged on the left and right sides of the magnetic base body 1. At the same time, the two string-binding parts 17 are respectively tied to the two main strings of the compound bow. That is, when the magnetic base is installed on the bowstring, the string-binding parts 17 can be respectively tied to the two main strings through the binding rope to meet the installation requirements of the magnetic base on the bowstring.

[0037] More specifically, recessed rope grooves 162 are provided at both ends of the rope installation portion 16 and the string binding portion 17. The rope end of the rope 4 is wound around the rope groove 162 of the rope installation portion 16. At the same time, the binding rope used to bind the main string and the string binding portion 17 is wound around the rope groove 162 of the string binding portion 17. That is, the rope groove 162 provides a rope winding space for the rope 4 and the binding rope, avoiding the problem of excessive protrusion and resulting in excessive volume, and improving the aesthetics. In addition, the rope groove 162 can also limit the stretching or binding rope wound therein, play a role in preventing it from falling off, and has higher stability.

[0038] More specifically, a second rope groove 171 is further provided on the side of each string-binding portion 17. At this time, the rope used to bind the main string and the string-binding portion 17 is also wound around the second rope groove 171. Since the second rope groove 171 is provided on the side of the string-binding portion 17, and the rope groove 162 is provided at both ends of the string-binding portion 17, the rope groove 162 and the second rope groove 171 can be located on different sides of the string-binding portion 17. Therefore, when the main string is subsequently tied to the string-binding portion 17 by the rope, the rope can be wound around different recessed areas in multiple positions, and more ropes can be tied with the same finished product volume. At the same time, it can further prevent the rope from falling off, and the structural design is more reasonable.

[0039] The compound bow dual-purpose magnetic base provided in this embodiment includes a magnetic base body 1 and a pressure plate 3; a plurality of embedding holes 13 are opened on the magnetic base body 1 and located on the outside of the through hole, and at the same time, one end of the through hole is provided with mutually connected steel ball placement holes 12, and one end of each embedding hole 13 extends to the connection between the steel ball placement hole 12 and the through hole, and at the same time, a magnet 2 is provided in each embedding hole 13, and the pressure plate 3 is provided at one end of the magnetic base body 1 and covers the side of the embedding hole 13 away from the steel ball prevention hole, the tail of the arrow is inserted through the through hole, and the steel ball is placed through the steel ball placement hole 12, so that the arrow is shot. and steel balls. In addition, by arranging the embedding holes 13 on the outside of the through hole and arranging the embedding holes 13 at intervals, there is material support between adjacent embedding holes 13 and between the embedding holes 13 and the through hole, which not only meets the installation requirements of the magnet 2 on the gear seat body, but also avoids the problem of reducing the structural strength of the magnetic seat body 1 due to the need to install a strong magnetic ring and expanding the through hole. The service life is longer and the safety of use is higher. In addition, the separate arrangement of the magnets 2 is realized. When part of the magnets 2 is damaged, the magnets 2 can be directly replaced without replacing all of them, which effectively reduces the cost of use.
