Description

Technical Field

[0001] The invention relates to the technical field of toy water bullet guns, in particular to a gun barrel and a muzzle compensator for improving the ballistics of a water bullet gun and a water bullet gun. Background Art

[0002] A water bullet gun is a toy gun used to fire water bullets. It uses a compressed spring that is released instantly to push air and blow the water bullet out of the barrel. Water bullets are made of sodium polyacrylate cross-linked copolymers. They are small round particles with a diameter of about 1mm during the storage stage. When used, they absorb water and expand to soft balls with a diameter of about 7mm. Because they are soft and fragile, they will not cause harm to the human body, so they are widely used as toy gun bullets. However, due to the light weight, small size, softness and fragility of water bullets, the range of water bullets is limited, and the trajectory of water bullets is difficult to control. Irregular deviations are very likely to occur, which seriously affects the accuracy of water bullet shooting and reduces the gaming experience.

[0003] In order to overcome the above-mentioned defects of water bullet guns, some barrel trajectory adjustment mechanisms or muzzle compensators have appeared in the prior art, such as the prior art utility model patent 200520121550.5, which is named as a toy gun trajectory adjustment mechanism. In the prior art, a rubber sleeve is arranged at the upper end of the barrel and embedded in the barrel, so that it is in friction contact with the upper part of the water bullet, and the water bullet is shot out by rotating upward. However, since the water bullet and the rubber sleeve wall are in single-point contact, the structure still has the problem of trajectory deviation after the water bullet is shot out, and the range is insufficient and the hit rate is not high.

[0004] There is also utility model patent 201721746756.6, named as a muzzle compensator for an electric water bullet gun. In this prior art, a T-shaped port is opened at the bottom of the compensation generator. Since the T-shaped port is connected to the atmosphere, the flow rate of the air above the water bullet is greater than the flow rate of the air below, so that the water bullet obtains an upward force, which in turn gives the water bullet an acceleration, thus improving the trajectory of the electric water bullet gun and increasing the range. However, the improvement of this structure still cannot meet the requirements of existing users for the range of water bullets.

[0005] It can be seen that the above existing water bullet guns still have inconveniences and defects in structure, method and use, and are in urgent need of further improvement. How to create a new barrel and muzzle compensator for improving the ballistics of water bullet guns and a water bullet gun, so that it can greatly improve the range and ballistic stability of water bullets, enhance the hit rate, improve the experience, and have a simple structure, easy operation and low cost. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a gun barrel for improving the ballistics of a water bullet gun, so that it can greatly improve the range and ballistic stability of the water bullet, enhance the hit rate, and improve the experience. It has a simple structure, is easy to operate, and has a low cost, thereby overcoming the shortcomings of existing water bullet guns.

[0007] In order to solve the above technical problems, the present invention provides a gun barrel for improving the ballistics of a water bullet gun, wherein the end of the gun barrel adopts a beveled structure, and the intersection line of the beveled surface of the beveled structure and the radial vertical surface of the gun barrel is a horizontal line, and the beveled surface is arranged obliquely forward and downward when the water bullet gun is shooting, so when the water bullet enters the beveled structure, the contact area between the water bullet and the inner wall of the gun barrel is gradually reduced.

[0008] According to a further improvement, the angle between the chamfered surface and the barrel wall is 5 to 40 degrees.

[0009] As a further improvement, the inner wall of the chamfered structure is smooth, or is provided with evenly distributed radial protrusions.

[0010] The present invention also provides a muzzle compensator for improving the ballistics of a water bullet gun, the muzzle compensator comprising a friction generating plate for being arranged at the end of an inner tube of a barrel of the water bullet gun, the friction generating plate being a cylindrical hollow tube having an inner diameter equal to that of the inner tube of the barrel, the end of the cylindrical hollow tube away from the inner tube of the barrel being a chamfered structure of the barrel for improving the ballistics of a water bullet gun.

[0011] As a further improvement, a countersunk hole for tightly inserting the gun barrel inner tube is provided on the inner wall of one end of the cylindrical hollow tube close to the gun barrel inner tube.

[0012] As a further improvement, the length of the friction generating sheet is 3 to 10 cm.

[0013] A further improvement includes a protective sleeve sleeved on the outside of the friction generating plate.

[0014] Further improvement, an adjustment hole is provided on the tube wall of the protective sleeve corresponding to the beveled end of the friction generating plate, and an adjustment plane is provided on the outer side wall of the friction generating plate corresponding to the adjustment hole, and the muzzle compensator also includes an adjusting screw, and the adjusting screw passes through the adjusting hole and abuts against the adjusting plane, and the upper and lower positions of the friction generating plate are adjusted by adjusting the depth of the adjusting screw.

[0015] As a further improvement, the friction generating sheet and the protective sleeve are tightly friction-fitted and fixedly connected by means of a concave-convex structure or a threaded connection.

[0016] The present invention also provides a water bullet gun, wherein the inner tube of the gun barrel of the water bullet gun adopts the gun barrel for improving the ballistics of the water bullet gun; or,

[0017] The end of the inner tube of the barrel of the water bullet gun is connected to the muzzle compensator for improving the ballistics of the water bullet gun.

[0018] After adopting such a design, the present invention has at least the following advantages:

[0019] 1. The present invention sets the end of the gun barrel into a beveled structure, so that the intersection line of the beveled surface of the beveled structure and the radial vertical surface of the gun barrel is a horizontal line, and ensures that the beveled surface is set forward and obliquely downward when the water bullet gun is shooting, so that when the water bullet enters the beveled structure, the contact surface between the water bullet and the inner wall of the gun barrel is gradually reduced. In addition, the friction forces on the upper and lower surfaces of the water bullet are different, and the friction force on the upper surface of the water bullet is greater than the friction force on the lower surface. Therefore, the water bullet rotates in the direction of greater friction during the forward process, and when the water bullet is shot from the water bullet gun, the rotation direction of the water bullet is upward. In addition, the upward rotating water bullet is based on the Magnus effect, so that the trajectory of the water bullet is stable and will not deviate to the left or right, and the Bernoulli effect generated based on the Magnus effect will also cause the water bullet to generate an upward lift, which can further offset the attraction of the earth's gravity on the water bullet, slow down the fall of the water bullet, and achieve the purpose of extending the range.

[0020] Moreover, due to the beveled surface at the end of the barrel, the water bullet is wrapped less and less by the inner wall of the barrel during its forward movement, and the friction force on the water bullet is also getting smaller and smaller, causing the rotation direction of the water bullet to gradually become fixed and have a stronger direction, thereby extending the controllable distance of the water bullet's trajectory and improving the hit rate.

[0021] 2. The present invention also connects a muzzle compensator to the end of the barrel so that the end of the friction generating plate included in the present invention is also arranged to be an oblique structure, which can not only play the role of upward spinning water bullets and extend the range, but also does not need to change the existing water bullet gun barrel structure. It only needs to install a muzzle compensator on the basis of the existing water bullet gun, which is simple and convenient and has a wide range of applications.

[0022] 3. By limiting the angle of the beveled surface and the length of the friction generating sheet, the length of the beveled section of the friction generating sheet and the symmetry of the friction surface can be ensured, further ensuring the stability of the water bullet trajectory.

[0023] 4. By setting up a protective sleeve, not only can the strength of the friction generating sheet be enhanced, but also the position of the friction generating sheet can be controlled through the adjustment hole and the adjustment screw thereon, so as to adapt it to different water gun barrels. And by setting up an adjustment platform on the outer wall of the friction generating sheet, it can be ensured that when the adjustment screw is tightened, no deflection occurs, thereby ensuring the adjustment effect of the friction generating sheet.

[0024] 5. The water bullet gun of the present invention can further increase the range of the water bullet by improving the end structure of the barrel or setting an improved muzzle compensator, so that the range can reach 15 to 20 meters, and ensure the stability of the water bullet trajectory, improve the hit rate, and enhance the gaming experience.

DETAILED DESCRIPTION

[0031] Embodiment 1

[0032] See attached Figures 1 to 3 As shown, the muzzle compensator for a water bullet gun in this embodiment includes a friction generating sheet 1 for being arranged at the end of the inner tube 2 of the water bullet gun barrel. It should be emphasized that the end of the inner tube of the gun barrel, the end of the gun barrel, and the end of the friction generating sheet in this application all refer to the end in the direction of water bullet ejection, that is, the muzzle direction of the water bullet gun is the end.

[0033] The friction generating plate 1 adopts a cylindrical hollow tube with an inner diameter equal to the inner diameter of the gun barrel inner tube 2. The end of the cylindrical hollow tube away from the gun barrel inner tube 2 is set to a bevel structure. The intersection line of the bevel surface 11 of the bevel structure and the radial vertical surface of the gun barrel inner tube 2 is a horizontal line. The bevel surface 11 is set forward and obliquely downward when the water bullet gun is shooting. When the water bullet 5 enters the bevel structure of the friction generating plate 1 from the gun barrel inner tube 2, the contact surface between the water bullet 5 and the inner wall of the friction generating plate 1 gradually decreases. In other words, when the water bullet 5 is inside the friction generating plate 1, only the upper part of the friction generating plate 1 is always in contact with the water bullet 5, and the lower part of the water bullet 5 gradually breaks away from the friction of the friction generating plate 1. In this way, the outer circumference of the water bullet 5 is subjected to different friction forces due to different friction media. The friction force of the part in contact with the friction generating plate 1 is large, and the friction force of the part in contact with the air is small. Therefore, the water bullet 5 will produce the effect of rotating toward the friction generating plate 1.

[0034] Specifically, the length of the friction generating sheet 1 is 3 to 10 cm. The angle between the beveled surface 11 and the wall of the cylindrical hollow tube is 5 to 40 degrees, preferably 30 degrees. The friction generating sheet of this structure can ensure the length of its beveled section and the symmetry of the friction surface, and further ensure the stability of the water bullet trajectory.

[0035] In this embodiment, the inner wall of the friction generating plate 1 close to the gun barrel inner tube 2 is provided with a countersunk hole 12 for the end of the gun barrel inner tube 2 to be tightly inserted, so as to realize the connection between the friction generating plate 1 and the gun barrel inner tube 2. Of course, other existing connection methods can also be used for connection, as long as the inner diameter of the gun barrel inner tube and the friction generating plate are ensured to smoothly transition.

[0036] In this embodiment, the inner wall of the friction generating plate 1 is smooth. Evenly distributed radial protrusions may also be provided on the inner wall of the chamfered structure of the friction generating plate 1 to further provide friction between the water bomb 5 and the inner wall of the friction generating plate 1 to ensure the upward rotation effect of the water bomb.

[0037] In addition, the muzzle compensator also includes a protective sleeve 3 which is sleeved on the outside of the friction generating plate 1 .

[0038] The protective sleeve 3 is a hollow cylinder having the same length as the friction generating plate 1 and is tightly sleeved on the outer circumference of the friction generating plate 1 to protect the friction generating plate.

[0039] As a further improvement, the protective sleeve 3 is provided with an adjustment hole 31 on the tube wall corresponding to the chamfered end of the friction generating plate 1, and an adjustment plane 13 is provided on the outer side wall of the friction generating plate 1 corresponding to the adjustment hole 31. The muzzle compensator also includes an adjustment screw, which passes through the adjustment hole 31 and abuts against the adjustment plane 13. By adjusting the depth of the adjustment screw, the upper and lower positions of the friction generating plate can be adjusted to adapt to different gun uses.

[0040] The adjustment plane 13 can prevent the problem that the arc-shaped outer side wall of the friction generating plate is easily offset when being squeezed by the adjustment screw, thereby better ensuring the smoothness of the adjustment of the friction generating plate.

[0041] When the muzzle compensator is applied to the muzzle of an existing water gun, the protective sleeve 3 and the friction generating sheet 1 are arranged in the barrel sleeve 4 of the water gun, and the friction generating sheet 1 is inserted and connected with the inner tube 2 of the barrel of the water gun. In addition, the ends of the protective sleeve 3 and the friction generating sheet 1 extend out of the ends of the barrel sleeve 4, so that the adjustment hole 31 on the protective sleeve 3 is arranged outside the barrel sleeve 4, which is convenient for the operation of the adjustment screw.

[0042] Of course, the friction generating sheet 1 and the protective sleeve 3 can also be connected by the existing concave-convex structure or by a threaded connection. The protective sleeve 3 and the barrel sleeve 4 can be connected and fixed by a tight friction fit, or by the existing concave-convex structure or by a threaded connection.

[0043] The use method and working principle of the muzzle compensator of the present invention are as follows: the muzzle compensator is installed at the end of the inner tube of the water bullet gun barrel, and the chamfered surface 11 of the friction generating plate 1 is controlled to be set forward and obliquely downward. After the water bullet 5 passes through the inner tube 2 of the barrel and enters the friction generating plate 1 of the compensator, the friction contact surface between the water bullet 5 and the friction generating plate 1 becomes smaller and smaller, and finally only the upper part of the water bullet 5 contacts the friction generating plate 1. Therefore, the water bullet 5 is finally ejected from the barrel in an upward spiral, as shown in the attached figure. Figure 4 After the water bullet 5 rotates upward, due to the Magnus effect, the trajectory of the water bullet is stable and will not deviate to the left or right. In addition, due to the Bernoulli effect brought about by the Magnus effect, an upward lift is generated, which offsets the attraction of the earth's gravity on the water bullet 5, reduces the falling of the water bullet 5, and achieves the purpose of extending the range of the water bullet. Figure 5 And because the contact area between the friction generating sheet 1 and the water bullet 5 is gradually reduced, the rotation direction of the water bullet 5 is gradually fixed, so that the water bullet 5 has a stronger direction, the hit rate is improved, the controllable distance of the trajectory is extended, and the range is improved.

[0044] The muzzle compensator of this embodiment can be set to different diameter specifications and is widely used in hand-pulled, electric, pneumatic and other water bullet guns. It can not only effectively solve the problem of insufficient water bullet range, but also effectively solve the problem of easy deviation of water bullet trajectory, providing a reliable guarantee for meeting the hit rate requirements of gamers.

[0045] Embodiment 2

[0046] The main difference between the second embodiment and the first embodiment is that the present embodiment directly improves the barrel of the existing water bullet gun. The end of the inner tube of the existing water bullet gun barrel is directly set to a beveled structure that is the same as the end structure of the friction generating plate, which can also make the water bullet shoot out of the barrel in an upward rotation manner, extend the shooting range, and improve the hit rate. It can also save the need to install a muzzle compensator later, which has the advantages of improving the integrity of the gun body and improving durability.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which all fall within the protection scope of the present invention.
