Detailed Description

Example one

Referring to fig. 1 to 3, the muzzle compensator for a water bullet gun according to the present embodiment includes a friction generating sheet 1 for being disposed at an end of an inner tube 2 of a barrel of the water bullet gun. It should be emphasized that in the present application, the end of the barrel inner tube, the end of the barrel, and the end of the friction generating piece all refer to the end of the ejection direction of the water, i.e. the muzzle direction of the water bullet gun.

The friction generating piece 1 adopts a cylindrical hollow tube with the inner diameter equal to that of the barrel inner tube 2, the tail end of the cylindrical hollow tube far away from the barrel inner tube 2 is arranged into a bevel structure, the intersecting line of a bevel plane 11 of the bevel structure and the radial vertical plane of the barrel inner tube 2 is a horizontal line, the bevel plane 11 is arranged towards the front oblique lower part when a water bullet gun shoots, and when the water bullet 5 enters the bevel structure of the friction generating piece 1 from the barrel inner tube 2, the contact surface between the water bullet 5 and the inner wall of the friction generating piece 1 is gradually reduced. That is, when the hydro-elastic 5 is in the friction generating sheet 1, only the upper part of the friction generating sheet 1 is always in contact with the hydro-elastic 5, and the lower part of the hydro-elastic 5 is gradually separated from the friction of the friction generating sheet 1, so that the outer circumference of the hydro-elastic 5 is subjected to different friction forces due to different friction media, the friction force of the part in contact with the friction generating sheet 1 is large, and the friction force of the part in contact with air is small, so that the hydro-elastic 5 can generate the effect of rotating towards the direction of the friction generating sheet 1.

Specifically, the length of the friction generation sheet 1 is 3 to 10 cm. The angle between the bevel 11 and the wall of the cylindrical hollow tube is 5-40 degrees, preferably 30 degrees. The friction generating sheet with the structure can ensure the length of the inclined cutting section and the symmetry of the friction surface, and further ensure the stability of the water bullet trajectory.

In this embodiment, a counter bore 12 for tightly inserting the end of the barrel inner tube 2 is formed in the inner wall of the end of the friction generating piece 1 close to the barrel inner tube 2, so as to connect the friction generating piece 1 and the barrel inner tube 2. Of course, other existing connection modes can be adopted for connection, as long as the stable transition of the inner diameters of the gun barrel inner tube and the friction generating piece is ensured.

The inner wall of the friction generation sheet 1 in this embodiment is smooth. Radial bulges which are uniformly distributed can be arranged on the inner wall of the beveling structure of the friction generating sheet 1 so as to further provide the friction force between the water bomb 5 and the inner wall of the friction generating sheet 1 and ensure the upward rotating effect of the water bomb.

The muzzle compensator further comprises a protective sleeve 3 which is sleeved outside the friction generating piece 1.

The protection sleeve 3 is a hollow cylinder with the same length as the friction generating piece 1, and is tightly sleeved on the periphery of the friction generating piece 1 to play a role in protecting the friction generating piece.

In a further improvement, the pipe wall of the protective sleeve 3 corresponding to the beveled end of the friction generating sheet 1 is provided with an adjusting hole 31, and the outer side wall of the friction generating sheet 1 corresponding to the adjusting hole 31 is provided with an adjusting plane 13. The muzzle compensator also comprises an adjusting screw, the adjusting screw penetrates through the adjusting hole 31 to abut against the adjusting plane 13, and the upper and lower positions of the friction generating sheet are adjusted by adjusting the depth of the adjusting screw, so that the muzzle compensator is suitable for different firearms.

This adjust plane 13 can play the easy skew problem of circular arc type lateral wall when preventing that friction from taking place the piece and receiving adjusting screw extrusion, the better smoothness of guaranteeing that friction takes place the piece and adjust.

When the muzzle compensator is applied to the muzzle of the existing water bullet gun, the protective sleeve 3 and the friction generating piece 1 are arranged in the barrel sleeve 4 of the water bullet gun, and the friction generating piece 1 is inserted and connected with the barrel inner tube 2 of the water bullet gun. And, the end portions of the protection sleeve 3 and the friction generating plate 1 are protruded out of the end portion of the barrel casing 4 so that the adjusting hole 31 of the protection sleeve 3 is provided outside the barrel casing 4 for facilitating the operation of adjusting the screw.

Of course, the friction generating sheet 1 and the protective sleeve 3 may be engaged with each other by a conventional concave-convex structure or fixedly connected by a screw connection. The protective sleeve 3 and the barrel sleeve 4 can be fixedly connected through tight friction fit, and can also be fixedly connected through the existing concave-convex structure clamping or in a threaded connection mode.

The utility model discloses muzzle compensator's application method and theory of operation do: the muzzle compensator is mounted on the end of the barrel inner tube of the water bullet gun, and the inclined plane 11 of the control friction generating piece 1 is arranged obliquely forward and downward. Then, after the water bullet 5 enters the friction generating piece 1 of the compensator through the barrel inner tube 2, the friction contact surface of the water bullet 5 with the friction generating piece 1 becomes smaller and smaller, and finally, only the upper part of the water bullet 5 is in contact with the friction generating piece 1, so that the water bullet 5 is finally ejected out of the barrel in an upward rotating manner, as shown in fig. 4. After the water bullet 5 rotates upwards in a directional mode, due to the Magnus effect, the water bullet trajectory is stable and cannot deviate leftwards or rightwards, and due to the Bernoulli effect caused by the Magnus effect, an upward lifting force is generated, the upward lifting force is used for offsetting the attraction of the earth attraction to the water bullet 5, the falling of the water bullet 5 is reduced, and the purpose of prolonging the shooting range of the water bullet is achieved, as shown in the attached drawing 5. And because the contact area of 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 stronger direction, the hit rate is improved, the trajectory controllable distance is prolonged, and the range is improved.

The muzzle compensator can be set to different diameter specifications, is widely applied to hand-pull, electric, pneumatic and other water bullet guns, can effectively solve the problem that a water ejection stroke is insufficient, can also effectively solve the problem that a water bullet trajectory is easy to deviate, and provides reliable guarantee for meeting the hit rate requirement of a player.

Example two

The second embodiment is different from the first embodiment in that the second embodiment is a direct improvement of the barrel of the existing water bullet gun. The tail end of the inner tube of the gun barrel of the existing water bullet gun is directly arranged into a beveling structure which is the same as the structure of the tail end of the friction generating sheet, so that the water bullet can be ejected out of the gun barrel in an upward rotating mode, the firing range is prolonged, and the hit rate is improved. And a muzzle compensator can be omitted from the later stage, so that the gun has the advantages of improving the integrity of the gun body and improving the durability.
