Description

Technical Field

[0001] The utility model relates to the technical field of arrow shaft accessories, in particular to an arrow shaft tail nail capable of reducing breakage. Background Art

[0002] A bow and arrow generally include a bow and an arrow. The bow is composed of an elastic bow arm and a tough bowstring. The arrow includes an arrowhead, an arrow shaft and an arrow tail. In order to ensure the stability of the direction of the arrow after being shot, the arrow also includes feathers. The arrow shaft is mostly made of wood or bamboo.

[0003] Usually the arrow shaft and the arrow tail are an integrated structure. In practice, the wooden or bamboo arrow tail is very easy to be damaged under severe impact. Once the arrow tail is damaged, the whole arrow is scrapped, which is extremely wasteful of resources and has high cost of use.

[0004] In the prior art, a tail nail is usually set at the tail of the arrow to protect the arrow shaft. The tail nail is usually fixed to the arrow shaft in a detachable connection manner. After the arrow shaft or the tail nail is damaged, it can be replaced independently without the need to replace the entire arrow shaft, thereby reducing the use cost of the arrow shaft.

[0005] However, the tail nail in the prior art is usually set on the arrow shaft by plugging, that is, a plug hole needs to be set at the tail of the arrow shaft. When the arrow shaft or the tail nail is subjected to impact, it is still easy to be damaged, and the arrow shaft or the tail nail cannot be effectively protected. After the tail nail is damaged, it needs to be replaced as a whole, resulting in high maintenance costs for the tail nail.

[0006] Therefore, the arrow shaft tail nail in the prior art has the technical problems of being easily damaged and having high maintenance cost. Summary of the invention

[0007] The utility model provides an arrow shaft tail nail with reduced damage, which solves the technical problems in the prior art that the arrow shaft tail nail is easily damaged and has high maintenance cost.

The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and obvious to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be practiced without these specific details.

[0038] It can be understood that, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another entity or operation, and are not intended to express or imply any actual relationship or order between these entities or operations.

[0039] The terms "comprises," "comprising," or any other variation thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0040] Reference Figures 1 to 6 As shown, an arrow shaft tail nail with reduced breakage includes a mounting seat 1 mounted on the arrow shaft and a tail nail body 2 mounted on the mounting seat 1;

[0041] The tail nail body 2 is installed on the mounting seat 1 through a connecting assembly 3, and the connecting assembly 3 includes a first connecting portion 31 threadedly connected to the mounting seat 1 and a second connecting portion 32 threadedly connected to the tail nail body 2, the first connecting portion 31 includes a tube 311 and a spherical groove 312 arranged at one end of the tube 311, the second connecting portion 32 includes a column 322 and a sphere 321 arranged at one end of the column 322, the sphere 321 cooperates with the spherical groove 312, and the depth of the spherical groove 312 is not less than the radius of the sphere 321, and the tube 311 is communicated with the spherical groove 312;

[0042] The tube body 311 is provided with a notch 313 that makes the tube body 311 easy to deform, the notch 313 is communicated with the spherical groove 312, and the notch 313 is communicated with the inner cavity of the tube body 311, the length of the notch 313 is smaller than the length of the tube body 311, the part of the tube body 311 not provided with the notch 313 is provided with an internal thread, and the mounting seat 1 is provided with a threaded column 11 that matches the internal thread;

[0043] The tail nail body 2 is further provided with an extension tube 21 , which is slidably connected to the mounting seat 1 , and a part of the mounting seat 1 is located in the extension tube 21 .

[0044] In this solution, the tail nail is set as a split structure. The tail nail includes a mounting seat 1 and a tail nail body 2. The mounting seat 1 and the tail nail body 2 can be replaced independently, so that the tail nail body 2 does not need to be replaced as a whole, thereby reducing the maintenance cost of the tail nail.

[0045] In addition, by providing the tube body 311 and the spherical groove 312, the ball 321 is inserted into the spherical groove 312, the tube body 311 can be elastically deformed, and the ball 321 can be installed in the spherical groove 312 by utilizing the elastic deformation of the tube body 311. During normal use, the position of the ball 321 relative to the spherical groove 312 is determined, that is, the position of the ball 321 relative to the tube body 311 does not change during normal use.

[0046] When the tail nail is subjected to a large force, such as overload or strong impact, the impact generated by the tail nail body 2 overcomes the force of the tube body 311, and the tube body 311 is elastically deformed under the action of the notch 313. The sphere 321 can move a part relative to the tube body 311, and the movement converts potential energy into kinetic energy, thereby absorbing a part of the impact, making the arrow shaft or the tail nail less likely to be damaged.

[0047] When the tail nail is subjected to a greater force or the movement distance of the ball 321 relative to the spherical groove 312 is too long, the tube body 311 is damaged, that is, part of the tube body 311 between the notches 313 and the notches 313 is broken. At this time, since the tube body 311 is threadedly connected to the mounting seat 1, only the tube body 311 needs to be replaced, and there is no need to replace the entire tail top, so the maintenance cost of the tail nail is low.

[0048] Reference Figures 1 to 6 As shown, in some embodiments, the mounting base 1 includes an inner cylinder 12 and an outer cylinder 13 arranged outside the inner cylinder 12, the inner cylinder 12 and the outer cylinder 13 are coaxially arranged, a cavity 14 is formed between the inner cylinder 12 and the outer cylinder 13, and a part of the arrow shaft extends into the cavity 14.

[0049] In addition to fixing the mounting seat 1, the outer tube 13 also has the function of an explosion-proof ring, thereby preventing the tail of the arrow shaft from cracking and extending the service life of the arrow shaft.

[0050] A connecting ring 15 for fixing the outer cylinder 13 is disposed at one end of the inner cylinder 12 close to the tail nail body 2 , and the inner cylinder 12 , the connecting ring 15 , and the outer cylinder 13 are an integrated structure.

[0051] In some embodiments, an end plate 16 is provided at one end of the inner cylinder 12 away from the connecting ring 15, the end plate 16 and the inner cylinder 12 are an integral structure, the threaded column 11 is provided on the end plate 16, and the threaded column 11 and the end plate 16 are an integral structure, and the threaded column 11 is coaxially arranged with the inner cylinder 12.

[0052] In some embodiments, the spherical groove 312 and the inner wall of the tube body 311 are smoothly transitioned through an arc angle, and grease is applied inside the spherical groove 312. The setting of the arc angle and the grease makes it easy for the sphere 321 to move relative to the tube body 311, and the tube body 311 is evenly stressed.

[0053] Reference Figures 1 to 6 As shown, in some embodiments, there are at least six notches 313, and the notches 313 are evenly distributed along the circumference of the tube body 311. The number of notches 313 is not limited and can be reasonably set as needed.

[0054] In some embodiments, the column 322 and the sphere 321 are an integrated structure, the column 322 is provided with an external thread, and the tail nail body 2 is provided with an internal thread.

[0055] The tail nail body 2 is provided with a tube portion 22 , which is coaxially arranged with the tail nail body 2 , and an internal thread matching the external thread of the column 322 is arranged on the tube portion 22 , and the tube portion 22 and the tail nail body 2 are an integrated structure.

[0056] In some embodiments, the extension tube 21 and the tail nail body 2 are an integrated structure.

[0057] The mounting seat 1 is provided with an identification layer for identifying the position of the tail nail body 2 relative to the mounting seat 1 . A spring 23 is also provided between the mounting seat 1 and the tail nail body 2 . The spring 23 is located in the extension tube 21 .

[0058] The spring 23 is used to absorb a part of the impact during the displacement of the tail nail body 2 relative to the mounting seat 1, so that the tube body 311, the tail nail body 2 and the mounting seat 1 are not easily damaged, further extending the service life of the arrow shaft tail nail.
