[0002] In the traditional steel ball shooting equipment, especially when shooting using compound bow, there are some significant limitations. Generally speaking, compound bow needs to be realized by binding steel ball seat on bowstring when launching steel ball. This method not only increases the complexity of operation, but also needs to be manually loaded after shooting steel ball, which significantly affects the continuity and speed of shooting.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] Please refer to Figures 1 to 4The utility model discloses a kind of continuous firing devices for steel ball shooting, including launch seat 10 and projectile magazine 30, launch seat 10 is equipped with loading hole 11, launch hole 12 and latch hole 13, the projectile magazine 30 is installed at loading hole 11, for accommodating steel ball and make steel ball continuously pass through loading hole 11, enter into launch hole 12, the latch hole 13 is set up with launch hole 12 each other, make the arrow rod 44 of compound bow pass through latch hole 13 and hit steel ball, complete the shooting operation of steel ball.

[0029] Specifically, the conventional compound bow usually needs to bind steel bead seat on the bowstring 43 when shooting steel ball, and the double bowstring 43 structure is needed to fix the two sides of the steel bead seat, which is not suitable for single bowstring 43 compound bow. Moreover, the steel bead seat needs to be manually refilled after shooting the steel ball, which affects the shooting speed. Therefore, after research and development, a continuous firing device is designed to be installed at the original position of the arrow stand of the compound bow. The arrow rod 44 without arrow is used to hit the steel ball in the launch hole 12, so that it is forced to shoot out. Therefore, it is not necessary to bind the steel bead seat on the bowstring 43, and the traditional compound bow can be used for shooting with the bowstring 43 structure, which is also suitable for single bowstring 43 compound bow.

[0030] Moreover, after shooting, only need to pull the bowstring 43 backward to drive the arrow rod 44 to move backward, so that the arrow rod 44 moves away from the launch hole 12, and the space of the launch hole 12 is emptied. The steel ball in the loading hole 11 above the launch hole 12 can fall downward under the action of gravity, pass through the loading hole 11, enter the launch hole 12, and simultaneously complete the operation of refilling the steel ball, so that the shooter can release the bowstring 43 again to shoot the arrow rod 44, so that the arrow rod 44 hits the refilled steel ball again, realizing the continuous shooting operation of steel ball.

[0031] As shown in Figure 2 , preferably, the latch hole 13 is coaxially arranged with the launch hole 12. Specifically, in order to improve the impact force of the arrow rod 44 on the steel ball, the launch hole 12 is coaxially arranged with the latch hole 13, so that the arrow rod 44 hits the middle position of the steel ball, which can further improve the accuracy of the steel ball.

[0032] As shown in Figure 1 and Figure 2 , preferably, the loading hole 11 is arranged above the launch hole 12, so that the steel ball falls into the launch hole 12 under the action of gravity.

[0033] Specifically, the composite bow is usually in a vertical state when shooting, and therefore, in order to facilitate the loading of the steel ball, the loading hole 11 is preferably arranged above the launching hole 12, so that the steel ball can naturally fall from the projectile magazine 30 to the loading hole 11 by gravity, and then fall into the launching hole 12, achieving the effect of continuous steel ball shooting.

[0034] For example, the loading hole 11 can be kept in a 90-degree vertical state with the launching hole 12, facilitating the falling of the steel ball. In another embodiment, in order to match the structural features of the composite bow itself, the angle between the loading hole 11 and the launching hole 12 can also be set to other angles, such as 45 degrees or 60 degrees, as long as it can ensure that the steel ball can automatically fall from the projectile magazine 30 to the loading hole 11 during normal use of the composite bow.

[0035] As shown in Figure 2 Preferably, the launching seat 10 is also provided with an auxiliary plug 14, which is arranged at the bottom of the launching hole 12 corresponding to the position where the steel ball falls, and one end of the auxiliary plug 14 is fixed to the launching seat 10, and the other end is in the same plane with the bottom surface of the launching hole 12.

[0036] Specifically, since the steel ball falls at the bottom of the launching hole 12 for a long time, and will form a certain friction with the bottom during launching, it is preferred to arrange an auxiliary plug 14 at the bottom of the launching hole 12 to assist the falling and launching of the steel ball. For example, the auxiliary plug 14 can be made of a high wear-resistant material (polyoxymethylene resin) to improve the stability and service life of the launching seat 10.

[0037] As shown in Figure 2 Preferably, the launching seat 10 is also provided with a sleeve 20, and the central axis of the sleeve 20 is provided with a through hole 21 for passing through the arrow shaft 44, and the through hole 21 is coaxially arranged with the latch hole 13.

[0038] Specifically, since the arrow shaft 44 will also form friction with the inner side wall of the latch hole 13 of the launching seat 10 during shooting, in order to improve its wear resistance and reduce its friction resistance, it is preferred to install a sleeve 20 at the position of the latch hole 13, and the sleeve 20 is made of polytetrafluoroethylene material in the prior art. Polytetrafluoroethylene (PTFE), commonly known as "Teflon", has a very low friction coefficient, can effectively reduce friction, and has strong wear resistance and is suitable for long-term use.

[0039] Secondly, in order to install the sleeve 20, it is also needed to open a counterbore with a diameter larger than that of the bolt hole 13 at the corresponding position of the launching seat 10 where the bolt hole 13 is located, so as to form a step position between the bottom of the counterbore and the bolt hole 13, when the sleeve 20 is installed in the counterbore, one end of the sleeve 20 can abut against the step position, so as to enhance the structural strength between the sleeve 20 and the launching seat 10.

[0040] As shown in Figure 1 and Figure 2 Preferably, one end of the bullet magazine 30 is provided with a bullet outlet 31, and the other end is provided with a magazine cover 32, the bullet outlet 31 is installed at the position of the bullet loading hole 11 of the launching seat 10, and the magazine cover 32 is connected to the opening of the bullet magazine 30 in a buckling manner.

[0041] Specifically, in order to facilitate the steel ball to pass through the bullet outlet 31 and the bullet loading hole 11 smoothly, it is preferred that the inner diameter of the bullet outlet 31 is equal to or larger than the inner diameter of the bullet loading hole 11. For example, preferably, the bullet outlet 31 is sleeved on the side wall of the bullet loading hole 11, and a threaded structure is formed to be fixedly connected.

[0042] Secondly, in order to facilitate the replenishment of steel balls in the bullet magazine 30, an opening can also be arranged at the end of the bullet magazine 30 away from the bullet loading hole 11, so that the steel balls can be replenished through the opening. The magazine cover 32 can also be arranged to seal the opening, so as to prevent the steel balls from falling out of the opening. The connection between the bullet outlet 31 and the inner wall of the bullet magazine 30 can also be provided with a certain chamfer, so that the steel balls in the bullet magazine 30 can be easily slid into the bullet outlet 31, and then fall into the bullet loading hole 11.

[0043] As shown in Figure 3 and Figure 4 Preferably, the utility model also provides a compound bow, which comprises the above-mentioned continuous shooting device, and further comprises a bow body 40 and an arrow rod 44, the bow body 40 is provided with an arrow rest mounting plate 41 and a bowstring 43, the launching seat 10 of the continuous shooting device is installed on the arrow rest mounting plate 41, one end of the arrow rod 44 penetrates into the bolt hole 13, and the other end is provided with an arrow buckle 45 for lapping the bowstring 43. The end of the arrow rod 44 close to the arrow buckle 45 is provided with an anti-falling seat 46, the anti-falling seat 46 is fixedly connected to the arrow rod 44, and the outer diameter of the anti-falling seat 46 is larger than the inner diameter of the bolt hole 13, so that the anti-falling seat 46 abuts against the launching seat 10 after the arrow rod 44 is shot, thereby preventing the arrow rod 44 from flying out.

[0044] Specifically, the composite bow can adopt the single bow string 43 or the double bow string 43 in the existing product. For the double bow string 43 composite bow, only one bow string 43 needs to be lapped on the arrow buckle 45 of the arrow rod 44 when the arrow rod 44 hits the steel ball. The arrow rod 44 is preferably made of carbon fiber material, which has the characteristics of being light and hard, thereby improving the hitting strength of the steel ball. And the front end is without arrow, and the rear end is provided with an arrow buckle 45 for lapping the bow string 43. The end of the arrow rod 44 close to the arrow buckle 45 is provided with a anti-falling seat 46 with an outer diameter of 20mm, which is made of aluminum alloy and is provided with a first shock absorbing member 47 made of soft rubber. The position corresponding to the anti-falling seat 46 of the launching seat 10 is provided with a second shock absorbing member 22 made of soft rubber, which is fixed on the PTFE sleeve 20. One end of the launching seat 10 is provided with a threaded hole 15, and the other end is provided with two supporting arms 16, which are connected with the supports 42 on the composite bow arrow platform mounting plate 41 through bolts and allow a certain angle adjustment.

[0045] As shown in Figure 1 , Figure 3 and Figure 4 , preferably, the anti-falling seat 46 is provided with a first shock absorbing member 47 on the side facing the bolt hole 13, and the first shock absorbing member 47 is fixed to the anti-falling seat 46.

[0046] Specifically, the first shock absorbing member 47 is preferably made of soft rubber material with certain elasticity and shock absorbing performance, thereby reducing the impact between the anti-falling seat 46 and the launching seat 10, and playing a buffering role.

[0047] As shown in Figure 2 , Figure 3 and Figure 4 , preferably, the launching seat 10 is provided with a second shock absorbing member 22 on the side facing the anti-falling seat 46, and the second shock absorbing member 22 is fixed to the sleeve 20.

[0048] Specifically, the second shock absorbing member 22 can also be made of soft rubber material with certain elasticity and shock absorbing performance, thereby further reducing the impact between the anti-falling seat 46 and the launching seat 10, and playing a buffering role. It can be understood that the second shock absorbing member 22 also needs to be provided with a through hole 21 corresponding to the bolt hole 13, so that the arrow rod 44 passes through the second shock absorbing member 22.

[0049] As shown in Figure 2 , preferably, one end of the launching seat 10 is provided with a threaded hole 15, thereby being fixedly connected to the arrow platform mounting plate 41 through a threaded structure, and the other end is provided with two supporting arms 16 on both sides, respectively. The arrow platform mounting plate 41 is provided with supports 42 on both sides corresponding to the positions of the supporting arms 16, and the supporting arms 16 and the supports 42 form a rotatable fixed connection.

[0050] Specifically, in order to further strengthen the connection between the launching seat 10 and the arrow platform mounting plate 41, the support arm 16 and the support 42 can be arranged on both sides of the two, which can be matched with each other to form a fixed connection. In order to facilitate the adjustment of the launching seat 10, the fixed connection between the support arm 16 and the support 42 can also have a certain rotational adjustment, so that it can be adjusted by a certain angle when connected through the threaded hole 15 by the bolt, thereby improving the freedom and shooting accuracy of the continuous firing device.

[0051] Example one: basic type continuous firing device

[0052] The continuous firing device of the embodiment comprises a launching seat 10 and a projectile magazine 30. The launching seat 10 is made of aluminum alloy material, which is light in weight and high in strength.

[0053] The launching seat 10 comprises a loading hole 11: the diameter is 12.5mm, which is used for receiving steel balls and is located directly above the launching hole 12. The launching hole 12: the diameter is 12mm, which is located at the front end of the launching seat 10 and is coaxial with the loading hole 11 in the vertical direction, which is used for the release of steel balls. The bolt hole 13: the diameter is 8mm, which is coaxial with the launching hole 12 in the transverse direction, which is used for the arrow rod 44 to pass through and hit the steel ball.

[0054] The projectile magazine 30: the inner wall is made of polycarbonate material, which has transparency and is convenient for observing the number of steel balls in the magazine. It contains 12 steel balls with a diameter of 12mm. The cover 32 is designed in a buckle type, which is convenient to open and close.

[0055] The archer pulls the bowstring 43, and the arrow rod 44 passes through the bolt hole 13. The arrow rod 44 hits the steel ball in the launching hole 12 to complete the launching. After launching, pulling the bowstring 43 makes the arrow rod 44 move backward, and the unlaunched steel ball falls from the projectile magazine 30 to the launching hole 12 under the action of gravity, preparing for the next launching. In addition, the auxiliary plug 14 is located at the bottom of the launching hole 12, which is made of polyformaldehyde material to improve the wear resistance and stability. The inner wall of the bolt hole 13 is covered with a PTFE material sleeve 20 to reduce friction and improve launching efficiency.

[0056] Example two: angle-adjustable continuous firing device

[0057] The continuous firing device of the embodiment is similar to example one, but the angle between the loading hole 11 and the launching hole 12 is adjusted to 60 degrees to adapt to different types of compound bows. The angle between the loading hole 11 and the launching hole 12 is 60 degrees, which ensures that the steel ball can smoothly enter the launching hole 12 under the action of gravity.

[0058] The arrow rod 44 still passes through the bolt hole 13 and completes the launching by hitting the steel ball, which is the same as example one. Under the action of gravity, the steel ball can more smoothly fall from the projectile magazine 30 to the launching hole 12, ensuring the stability of the launching speed.

[0059] Example three: high-capacity bullet magazine 30 of the repeating device

[0060] The repeating device of this embodiment adopts the enhanced bullet magazine 30 design, which can accommodate up to 50 steel balls with a diameter of 12mm.

[0061] Bullet magazine 30 design: with the structure of increasing height and internal partition groove design, it ensures that the steel balls can be effectively distributed and smoothly fall. The inner diameter of the bullet outlet 31 is the same as the loading hole 11, which ensures that the steel balls can pass smoothly.

[0062] During the firing process, the steel balls fall freely in the magazine, smoothly enter the firing hole 12, and the continuous firing capacity is increased to 50 shots. This design is suitable for occasions that require rapid multiple firing, reducing the time for replenishment.

[0063] Example four: improved buffer system of the repeating device

[0064] This embodiment enhances the buffer system to reduce the impact force during firing and prolong the service life.

[0065] Buffer design: the side of the anti-falling seat 46 facing the bolt hole 13 is provided with a first shock-absorbing piece 47 made of soft rubber with a thickness of 5mm. The side of the firing seat 10 facing the anti-falling seat 46 is also provided with a second shock-absorbing piece 22.

[0066] During firing, the shock-absorbing piece effectively reduces the impact force between the anti-falling seat 46 and the firing seat 10, ensuring stable firing and reducing the wear and tear on the equipment, improving the durability of the equipment.

[0067] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
