Description

Technical Field

[0001] This utility model relates to the field of shooting equipment technology, and in particular to a crossbow. Background Technology

[0002] A crossbow bolt is a special arrow used with a crossbow. A crossbow bolt typically consists of four parts: the shaft, the arrowhead, the fletching, and the arrow shaft. The shaft, as the main body of the arrow, is often made of hardwood, bamboo, or modern composite materials (such as carbon fiber). These materials ensure the arrow's rigidity and stability during flight, and can also withstand the enormous energy released by the crossbow mechanism when fired, ensuring that the arrow can be launched at high speed towards the target.

[0003] During the use of crossbows, the arrowhead and string clip, as key components, are frequently subjected to tremendous force and friction, making them prone to damage, especially the string clip, which has a relatively high failure rate. When a string clip is damaged, users usually need to install a new one; however, existing string clip designs often present inconvenience for replacement. Even if the string clip is successfully replaced, slight deviations in its installation position often result in an inconsistency between the angle between the string clip and the fletching and the original, which can easily cause the arrow to deviate during flight, thus affecting shooting accuracy. Summary of the Invention

[0004] To address the above problems, this application provides a crossbow bolt with a shaft, an arrowhead at the front end of the shaft, a string clip at the end of the shaft, and fletchings at the tail end of the shaft, the fletchings including primary fletchings and secondary fletchings. A string clip seat is provided between the shaft and the string clip, the string clip has a string groove, the string clip seat has a string clip positioning groove, and the string clip has a string clip positioning protrusion. When the string clip positioning protrusion is inserted into the string clip positioning groove, the primary fletchings are perpendicular to the string groove.

[0005] In one embodiment, the string clamp seat is in the shape of a cylindrical tube, the string clamp positioning groove is disposed on the inner wall of the string clamp seat, the string clamp includes a string clamp insertion post and a string clamp body, the string clamp positioning protrusion is disposed on the string clamp insertion post, and the string groove is disposed on the string clamp body.

[0006] In one embodiment, two sets of the string clamp positioning protrusions and the string clamp positioning grooves are arranged opposite to each other.

[0007] In one embodiment, the primary feather is one piece, the secondary feather is two pieces, and the primary feather and the secondary feather are set at 120° to each other.

[0008] In one embodiment, an arrow seat is provided between the arrow shaft and the arrowhead. The arrowhead is provided with an arrow tip, an arrow connecting post, and a threaded rod. The arrow seat is in the shape of a cylindrical tube and includes a connecting post mounting cavity and a threaded rod mounting cavity.

[0009] In one embodiment, the string clamp insertion post is provided with a plurality of fastening protrusions along the axial direction.

[0010] In one embodiment, both the arrowhead holder and the string clip holder are fixedly mounted on the arrow shaft with glue.

[0011] The beneficial effects of this utility model are as follows:

[0012] This application discloses a crossbow bolt that, by setting a string clip positioning protrusion and a string clip positioning groove, ensures that after the string clip is installed on the arrow shaft, the fletching and string clip maintain a predetermined position, i.e., the fletching is perpendicular to the string groove. Only when the fletching is perpendicular to the string groove can the fletching remain perpendicular to the string groove and facing outwards during the draw of the crossbow string, making the arrow's flight smoother and improving its stability. When the string clip is damaged due to prolonged use or accidental damage, the precise cooperation between the string clip positioning protrusion on the string clip and the string clip positioning groove on the string clip seat allows the string clip to be accurately installed on the string clip seat, which is convenient and quick. Each installation ensures that the fletching is perpendicular to the string groove, guaranteeing the stability and accuracy of the arrow during firing and maintaining high shooting precision. The tight cooperation between the string clip positioning protrusion and the string clip positioning groove effectively prevents the string clip from deflecting during installation, avoiding decreased shooting accuracy or abnormal arrow flight trajectory caused by deflection.

[0024] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0025] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] like Figure 1-3 As shown, a crossbow bolt is provided with an arrow shaft 1, an arrowhead 2 at the front end of the arrow shaft 1, a string clip 3 at the end of the arrow shaft 1, and fletching 4 at the tail end of the arrow shaft 1. The fletching 4 includes primary fletching 41 and secondary fletching 42. A string clip seat 5 is provided between the arrow shaft 1 and the string clip 3. A string groove 31 is provided on the string clip 3. A string clip positioning groove 51 is provided on the string clip seat 5. A string clip positioning protrusion 32 is provided on the string clip 3. When the string clip positioning protrusion 32 is inserted into the string clip positioning groove 51, the primary fletching 41 is perpendicular to the string groove 31.

[0027] Specifically, the arrow shaft 1 is the main body of the crossbow bolt, connecting the arrowhead 2, the string clip 3, and the fletching 4. The arrowhead 2 is located at the front end of the arrow shaft 1 and is used to penetrate the target during firing. The string clip seat 5 is located between the arrow shaft 1 and the string clip 3, serving to connect and support the string clip 3. The string clip 3 has a string groove 31 for holding the bowstring during firing. The string clip seat 5 is designed with a string clip positioning groove 51 to receive the string clip positioning protrusion 32 on the string clip 3. The precise matching of the string clip positioning protrusion 32 and the string clip positioning groove 51 ensures the stable installation and precise positioning of the string clip 3 on the string clip seat 5. By setting the string clip positioning protrusion 32 and the string clip positioning groove 51, after the string clip 3 is installed on the arrow shaft 1, the fletching 4 maintains a predetermined position with the string clip 3, that is, the fletching 41 is perpendicular to the string groove 31. Only when the fletching 41 is perpendicular to the string groove 31 can the fletching 41 remain perpendicular to the string groove 31 and facing outwards during the draw of the crossbow string, making the arrow's flight smoother and improving its stability. When the string clip 3 is damaged due to prolonged use or accidental damage, the precise cooperation between the string clip positioning protrusion 32 on the string clip 3 and the string clip positioning groove 51 on the string clip seat 5 allows the string clip 3 to be accurately installed onto the string clip seat 5, which is convenient and quick. Each installation ensures that the fletching 41 is perpendicular to the string groove 31, guaranteeing the stability and accuracy of the arrow during firing and maintaining high shooting precision. The tight cooperation between the string clip positioning protrusion 32 and the string clip positioning groove 51 effectively prevents the string clip 3 from deflecting during installation, avoiding decreased shooting accuracy or abnormal arrow flight trajectory caused by deflection.

[0028] like Figure 3 , 4 As shown, the string clamp seat 5 is in the shape of a cylindrical tube, and the string clamp positioning groove 51 is provided on the inner wall of the string clamp seat 5. The string clamp 3 includes a string clamp insertion post 33 and a string clamp body 34. The string clamp positioning protrusion 32 is provided on the string clamp insertion post 33, and the string groove 31 is provided on the string clamp body 34.

[0029] Specifically, the string clip seat 5 is cylindrical, allowing the string clip 3 to be easily inserted into it, and a stable connection is achieved through the engagement of the string clip positioning groove 51 on the inner wall and the string clip positioning protrusion 32. The string clip 3 consists of two parts: the string clip insertion post 33 and the string clip body 34. The string clip positioning protrusion 32 is located on the string clip insertion post 33 and mates with the string clip positioning groove 51. The engagement of the string clip positioning protrusion 32 and the string clip positioning groove 51 not only ensures the stable installation of the string clip 3 on the string clip seat 5, but also achieves precise positioning of the string clip 3 on the string clip seat 5, thereby ensuring the stability and accuracy of the arrow during launch. The cylindrical design of the string clip seat 5 and the string clip insertion post 33 allows the string clip 3 to be tightly inserted, preventing the string clip 3 from loosening or falling off during launch.

[0030] like Figure 3 As shown, there are two sets of chord clamp positioning protrusions 32 and chord clamp positioning grooves 51 arranged opposite to each other.

[0031] Specifically, by setting two sets of string clip positioning protrusions 32 and string clip positioning grooves 51, the number of connection points between the string clip 3 and the string clip seat 5 is increased, thereby improving the stability of the connection and making the string clip 3 more stable and less prone to loosening or falling off. The setting of two sets of positioning points helps to extend the service life of the string clip 3 and the string clip seat 5 and reduce damage caused by stress concentration.

[0032] like Figure 3 As shown, primary feather 41 is one piece, and secondary feather 42 is two pieces, with primary feather 41 and secondary feather 42 set at 120° to each other.

[0033] Specifically, the primary feather 41 and the secondary feather 42 are set at 120° to each other, which can reduce air resistance during the arrow's flight, while providing the necessary lift and stability to ensure that the arrow stays in a straight line during flight and reduces deflection and shaking.

[0034] like Figure 1 , 2 As shown, an arrow seat 6 is provided between the arrow shaft 1 and the arrowhead 2. The arrowhead 2 is provided with an arrow tip 21, an arrow connecting post 22, and a threaded rod 23. The arrow seat 6 is in the shape of a round tube and includes a connecting post mounting cavity and a threaded rod mounting cavity.

[0035] Specifically, the arrow holder 6 is tubular in shape, tightly enclosing the end of the arrow shaft 1. It engages with the arrow connecting post 22 and threaded rod 23 of the arrow 2 via an internal connecting post mounting cavity (not shown in the figure) and threaded rod mounting cavity, ensuring a secure connection between the arrow 2 and the arrow shaft 1. The threaded connection between the arrow holder 6 and the arrow 2 is not only robust but also facilitates quick replacement of the arrow 2, allowing for easy unscrewing of the old arrow and insertion of a new one, thereby improving shooting efficiency and flexibility.

[0036] like Figure 4 As shown, the string clamp insertion post 33 is provided with several fastening protrusions 35 along the axial direction.

[0037] Specifically, by setting a fastening protrusion 35, the friction between the string clip 3 and the string clip seat 5 is increased, ensuring that the string clip 3 can be firmly fixed on the string clip seat 5.

[0038] like Figure 1 As shown, the arrowhead holder 6 and the string clip holder 5 are both fixedly installed on the arrow shaft 1 with glue.

[0039] Specifically, using glue to fix and install the arrow holder 4 and the chord clip holder 5 does not require complicated processes or equipment, and the installation method is simple and quick, which can greatly improve production efficiency.

[0040] The beneficial effects of this application compared with the prior art are as follows:

[0041] This application discloses a crossbow bolt comprising a shaft 1, an arrowhead 2 at the front end of the shaft 1, a string clip 3 at the rear end of the shaft 1, and fletching 4 at the rear end of the shaft 1. The fletching 4 includes primary fletching 41 and secondary fletching 42. A string clip seat 5 is provided between the shaft 1 and the string clip 3. The string clip 3 has a string groove 31, and the string clip seat 5 has a string clip positioning groove 51. The string clip 3 has a string clip positioning protrusion 32. When the string clip positioning protrusion 32 is inserted into the string clip positioning groove 51, the primary fletching 41 is perpendicular to the string groove 31. By providing the string clip positioning protrusion 32 and the string clip positioning groove 51, after the string clip 3 is installed on the shaft 1, the fletching 4 and the string clip 3 maintain a predetermined position, that is, the primary fletching 41 is perpendicular to the string groove 31. Only when the fletching 41 is perpendicular to the string groove 31 can the fletching 41 remain perpendicular to the string groove 31 and facing outwards during the draw of the crossbow string, making the arrow's flight smoother and improving its stability. When the string clip 3 is damaged due to prolonged use or accidental damage, the precise cooperation between the string clip positioning protrusion 32 on the string clip 3 and the string clip positioning groove 51 on the string clip seat 5 allows the string clip 3 to be accurately installed onto the string clip seat 5, which is convenient and quick. Each installation ensures that the fletching 41 is perpendicular to the string groove 31, guaranteeing the stability and accuracy of the arrow during firing and maintaining high shooting precision. The tight cooperation between the string clip positioning protrusion 32 and the string clip positioning groove 51 effectively prevents the string clip 3 from deflecting during installation, avoiding decreased shooting accuracy or abnormal arrow flight trajectory caused by deflection.
