Description

Technical Field

[0001] This utility model belongs to the field of composite bow technology, specifically relating to a non-binding center launching magnetic base for a dual-purpose composite bow. Background Technology

[0002] A dual-purpose compound bow is a type of bow that can be used to fire both arrows and projectiles. It typically has a double-string, double-wheel structure, with a central launcher mounted on the bowstring. This launcher usually uses a magnetic base with some magnetism, primarily for positioning the arrow fletching or mounting steel balls, and also for attaching a D-ring to the release mechanism. Traditionally, the launcher is tied to the two parallel bowstrings using a string guard. This binding process is cumbersome, time-consuming, and labor-intensive, requiring considerable experience; otherwise, the launcher may not be securely fixed. Therefore, it is essential to develop a binding-free launcher and a novel installation method. Utility Model Content

[0003] In response to the above situation, this utility model provides a non-binding center launching magnetic base for dual-purpose composite bows, which completely changes the traditional launching base installation method, eliminating the need for time-consuming and laborious winding and binding, making the installation of the launching base simpler and more convenient.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A non-binding center firing magnet for a dual-purpose composite bow includes two bowstrings of the dual-purpose composite bow and a center firing seat fixed on the two bowstrings. The center firing seat is composed of a front locking seat and a rear locking seat that are fastened together between the two bowstrings.

[0006] Both mounting brackets consist of rectangular blocks with a central hole in the middle. A circular magnetic ring for positioning the arrow's fletching or mounting a steel ball is coaxially nested within the central hole of the front mounting bracket. When shooting an arrow, the fletching is inserted into the central hole; when firing a ball, the rear of the ball is positioned within the central hole.

[0007] The left and right sides of the two card holders are respectively fixed with clamping parts for cooperating with the clamping clamp to clamp the bowstring, and the clamping parts of the two card holders are provided with clamping claw grooves on the side of the clamping parts closest to the bowstring.

[0008] The upper and lower sides of the two card holders are respectively provided with threaded parts for screws to pass through and lock the two card holders, and the middle of the threaded parts of the two card holders is coaxially provided with a screw-locking through hole.

[0009] Furthermore, the interior of the central hole of the rear card holder is integrally formed with a middle partition extending along its longitudinal diameter direction.

[0010] Furthermore, a circular guide bevel is provided on the front edge of the central hole of the front card holder, which mainly serves as a guide when the arrow tail is inserted and when the steel ball is installed.

[0011] Furthermore, both the clamping part and the screw connection part are integrally formed with the main body of the two card seats and are extended outwards.

[0012] Preferably, the main body of the front and rear card seats is provided with two sets of symmetrical clamping parts on the left and right sides, and the four sets of clamping parts are provided with semi-circular claw grooves on the side near the bowstring.

[0013] Preferably, the radius of the gripper groove is slightly smaller than the radius of the bowstring, ensuring that the gripping parts of the two grippers can firmly engage the outer surface of the bowstring when locked.

[0014] Preferably, the front and rear card holders each have a set of screw connections on their upper and lower sides. Each of the two sets of screw connections has a corresponding tightening through hole in its center, and a screw is fitted into each of the two sets of tightening through holes. Furthermore, the inner wall of the tightening through hole of either the front or rear card holder has an internal thread. When the screw is tightened into the internal thread, the clamping parts of the two card holders firmly grip the bowstring.

[0015] Preferably, both sets of threaded portions are “Ω” shaped, and the neck of both sets of threaded portions is provided with a groove for positioning and binding the D-ring, so as to facilitate hooking the release device when pulling the string.

[0016] This utility model also includes other components that enable its normal use, all of which are conventional means in the field. In addition, devices or components not limited in this utility model, such as the dual-purpose composite bow and its bowstring, D-ring, etc., all adopt the prior art in the field.

[0017] The beneficial effects of this utility model are as follows:

[0018] This untethered center-launching magnetic base completely changes the traditional launcher installation method. It eliminates the need for time-consuming and laborious winding and binding. Simply tightening two locking screws is enough to hold the launcher firmly on the two bowstrings, making the launcher installation simpler, more convenient, and more secure and reliable.

[0025] Example

[0026] like Figure 1-3 As shown, a non-binding center firing magnetic base for a dual-purpose compound bow includes two bowstrings 1 of the dual-purpose compound bow and a center firing base fixed to the two bowstrings. The center firing base consists of two locking pieces, a front locking piece 2 and a rear locking piece 3, which are fastened and installed between the two bowstrings and interlock with each other. Traditional firing bases typically have only one locking piece that is secured between the two bowstrings by wrapping and binding with a string guard rope, such as the dual-firing point mounting structure for a dual-purpose bow disclosed in patent document CN217210555U. Dual-purpose compound bows and their bowstrings are existing technology in this field and will not be described in detail here.

[0027] Both card holders are rectangular block structures with a central hole in the middle. The central hole of the front card holder is coaxially nested with an interference fit for positioning the arrow tail or installing steel balls. The central hole of the rear card holder also has an integrally formed middle partition 5 extending along its longitudinal diameter, which divides the central hole of the rear card holder into two crescent-shaped holes.

[0028] The front edge of the central hole of the front card holder is also provided with a circular guide bevel 6, which can play a certain guiding role when the arrow tail is inserted into the central hole, and can also play a guiding role and increase the contact area of ​​the rear side of the steel ball when installing the steel ball into the central hole.

[0029] When shooting an arrow, insert the tail of the arrow shaft into the center hole, with the middle stop abutting the rear of the tail to limit its movement. When shooting marbles, place the back of the marble in the center hole. Because there is a circular magnetic ring in the middle of the launcher, it has a certain magnetism and can hold the marble in place so that it will not fall. However, the magnetism should not be too strong so as not to interfere with the launching speed of the marble.

[0030] Both the clamping part and the screw connection part are integrally formed with the main body of the two card seats and extend outwards. Two sets of symmetrical clamping parts 7 are provided on the left and right sides of the main body of the front and rear card seats. Each of the four sets of clamping parts has a semi-circular claw groove 8 on the side near the bowstring. The bowstring is coaxially fixed in place by the clamping part between the claw grooves of the clamping parts of the two card seats.

[0031] The radius of the claw groove is slightly smaller than that of the bowstring, ensuring that when the clamping parts of the two clamps are locked, the inner side of the circular clamping hole formed by the corresponding two semi-circular claw grooves can firmly bite the outer surface of the bowstring.

[0032] Each of the upper and lower sides of the main body of the front and rear card seats is provided with a set of threaded parts 9. Each of the two sets of threaded parts is provided with a screw-tightening through hole 10 in the middle. A screw 11 is fitted into the screw-tightening through hole of the two sets of screw-tightening through holes. An internal thread 12 is provided on the inner wall of the screw-tightening through hole of the rear card seat. Of course, it is also possible to provide an internal thread on the inner wall of the screw-tightening through hole of the front card seat (and it is also possible to provide an internal thread in the screw-tightening through hole of one of the threaded parts of the front card seat and an internal thread in the screw-tightening through hole of one of the threaded parts of the rear card seat. All of the above conventional choices of various configuration methods are included within the protection scope of this utility model). However, it should be noted that the inner wall of the screw-tightening through hole of the corresponding card seat is preferably smooth, and the hole diameter is slightly larger than the outer diameter of the screw thread, so as to ensure that the screw can pass through smoothly and can be screwed into the internal thread to firmly lock the front and rear card seats, and at the same time make the clamping part of the two card seats firmly bite the bowstring.

[0033] Both sets of threaded connections are Ω-shaped, and both sets of threaded connections have a groove 13 at their necks for positioning and binding the D-ring 14. The D-ring is a semi-circular ring in the shape of a D, formed by binding both ends of a special rope into the groove of the threaded connection. It mainly serves to facilitate hooking the release device when the string is pulled. The D-ring is prior art in this field and will not be described in detail here.

[0034] The technical solution of this utility model is not limited to the specific embodiments described above. Without departing from the scope and spirit of the described embodiments, many modifications and changes will be obvious to those skilled in the art. Any technical modifications made within the spirit and principles of this utility model shall fall within the protection scope of this utility model.
