[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 8 As shown in the figure, this application provides a ball gun, including a gun shell 1, an air cylinder assembly 2, a piston rod 3, a stopper 4, a first elastic component 5, a second elastic component 6, a release frame 7, and a sliding component 8. The gun shell 1 has a constricting cylinder 101, and an annular baffle 102 is provided on the inner wall of the constricting cylinder 101. The air cylinder assembly 2 is disposed on the gun shell 1, and an annular baffle 21 is provided on the inner wall of the air cylinder assembly 2. One end of the air cylinder assembly 2 is connected to the constricting cylinder 101. The inner diameter of the annular baffle 102 is smaller than the inner diameter of the air cylinder assembly 2, thereby ensuring stable support of the first elastic component 5 without affecting the airflow. The piston rod 3 is located inside the gun shell 1, and a piston 10 is provided at one end of the piston rod 3. The piston 10 is located inside the air cylinder assembly 2, and the other end of the piston rod 3 extends out of the air cylinder. The abutting member 4 and the first elastic member 5 are provided. The abutting member 4 is movably disposed in the air cylinder assembly 2. The first elastic member 5 is located in the air cylinder assembly 2, with one end abutting against the abutting member 4 and the other end abutting against the annular baffle 21.

[0023] The second elastic component 6 is disposed between the piston 10 and the gun housing 1, and the release bracket 7 is disposed inside the gun housing 1. The sliding component 8 is slidably connected to the gun housing 1, and a movable locking component 9 is provided on the sliding component 8. The movable locking component 9 and the piston rod 3 are engaged. Under the action of external force, the sliding component 8 can move towards the rear of the gun housing 1, driving the piston 10 to move and compressing the second elastic component 6. When the sliding component 8 drives the movable locking component 9 to move to the release bracket 7, the release bracket 7 triggers the movable locking component 9 to release the piston rod 3, the second elastic component 6 is elastically released, and the piston rod 3 is pushed back to its original position.

[0024] When playing with the ball gun provided in this application, soft balls can be inserted into the air cylinder assembly 2 through the constricting tube 101. The inner diameter of the annular baffle 102 is slightly smaller than the outer diameter of the soft ball, which can stop the soft ball and prevent it from falling out of the constricting tube 101 when not shooting. The inner cylinder of the air cylinder assembly 2 is relatively long, allowing multiple soft balls to be inserted. During the insertion of the soft ball, the soft ball will gradually compress the first elastic component 5 through the abutment 4. The first elastic component 5 will also apply elastic force to the soft ball through the abutment 4, so that the outermost soft ball is pressed against the annular baffle 102, ensuring that the gas inside the air cylinder assembly 2 does not easily leak out, facilitating stable pressurization and thus squeezing out the outermost soft ball. During the pressurization process inside the air cylinder assembly 2, the user only needs to push the slider 81 on the slider 8 by hand, so that it slides along the outer surface of the gun shell 1 towards the rear. At this time, the sliding bracket 82 moves synchronously inside the gun shell 1, driving the movable locking component 9 to move together. Because the movable locking member 9 and the mating rod 32 of the piston rod 3 are in a limited engagement state, during the sliding process, the movable locking member 9 will drive the mating rod 32 and the entire piston rod 3 to move. The piston 10 slides inside the air cylinder assembly 2, compressing the second elastic component 6, and at the same time, the air pressure inside the air cylinder assembly 2 changes. When the sliding frame 82 moves to its limit position, the movable locking member 9 contacts the release frame 7. The protrusion 72 on the release frame 7 pushes the swing mating part 91 of the movable locking member 9, causing the movable locking member 9 to rotate around the fixed axis 822. The locking part 92 moves accordingly and disengages from the mating rod 32, releasing the limitation on the piston rod 3. At this time, the second elastic component 6 elastically releases, quickly pushing the piston rod 3 back to its original position. The piston 10 moves rapidly towards the constriction tube 101 side inside the air cylinder assembly 2, the air pressure inside the air cylinder assembly 2 increases, and the soft bullet is fired from the muzzle.

[0025] Furthermore, as the piston 10 moves away from the constriction cylinder 101, the air pressure inside the air cylinder assembly 2 is lower than the external pressure. The inner core 42 of the abutment 4 moves under the external air pressure, opening the vent 4111 and allowing outside air to enter the air cylinder assembly 2, ensuring pressure balance. Then, the first elastic component pushes the next soft bullet against the annular baffle 102, preparing for the next firing. The entire firing process is smooth and continuous, eliminating the need for reloading after each shot, unlike traditional soft bullet launchers. This greatly enhances the fun and continuity of shooting, better meeting the user's need for continuous firing.

[0026] The ball gun disclosed in this application achieves more stable and longer-range bullet firing through a unique air cylinder assembly 2 and piston rod 3 design. Simultaneously, the innovative structure, incorporating a stopper 4, a first elastic component 5, a second elastic component 6, and a release mechanism 7, makes the entire shooting process fun and varied. Children can experience different shooting effects through different operating methods while playing, greatly enhancing the entertainment and appeal of the toy gun.

[0027] In some possible implementations, the abutting member 4 includes a cylindrical shell 41 and an inner core 42. The cylindrical shell 41 is in sliding contact with the inner wall of the air cylinder assembly 2, and a vent 4111 is provided on the cylindrical shell 41. The inner core 42 is located inside the cylindrical shell 41, and the first elastic member 5 abuts against the inner core 42, causing the inner core 42 to close the vent 4111. As the piston 10 moves away from the constricting cylinder 101, the air pressure inside the air cylinder assembly 2 is lower than the external pressure. The inner core 42 moves under the action of the external air pressure, opening the vent 4111. When the air pressure inside the air cylinder assembly 2 gradually returns to equilibrium with the external pressure, the first elastic member 5 pushes the inner core 42 again, causing it to close the vent 4111 again, thereby ensuring that a relatively closed space can be formed inside the air cylinder assembly 2 before the next launch, facilitating the re-pressurization and launch of the soft ball. This design cleverly utilizes air pressure changes and the function of elastic components to achieve automatic blocking and air pressure balance of the soft ball, greatly improving the ease of use and firing efficiency of the ball gun. At the same time, the reasonable structural design of the blocking component 4 makes the entire firing process more stable and reliable, reducing the possibility of malfunctions.

[0028] In some possible implementations, the shell 41 includes an end wall 411 and a cylindrical wall 412 located around the edge of the end wall 411. The vents 4111 are provided on the end wall 411, and the cylindrical wall 412 fits into the inner diameter of the air cylinder assembly 2. Under the action of the first elastic member 5, the inner core 42 fits into the end wall 411, covering each of the vents 4111. This structural design ensures the airtightness of the air cylinder assembly 2 in the non-firing state, effectively preventing gas leakage and providing stable conditions for pressure accumulation during firing. When the piston 10 moves, causing a decrease in the internal pressure of the air cylinder assembly 2, the external pressure pushes the inner core 42 away from the end wall 411, opening the vents 4111, allowing external air to quickly enter, balancing the internal and external pressures, and avoiding component damage or firing instability that may be caused by excessive pressure difference. Subsequently, the rebound force of the first elastic member 5 causes the inner core 42 to re-fit tightly against the end wall 411, sealing the vents 4111, preparing for the next firing.

[0029] In some possible implementations, a guide hole 4112 is provided at the center of the end wall 411, and each of the vents 4111 is arranged circumferentially around the guide hole 4112. The inner core 42 has an inner core body 421 and a guide post 422. The guide post 422 is disposed through the guide hole 4112, and the inner core body 421 can slide along the cylinder wall 412 to close or open the vents 4111. The cooperative design of the guide hole 4112 and the guide post 422 provides precise guidance for the movement of the inner core 42, ensuring that the inner core 42 can move stably along a predetermined trajectory when the air pressure changes, without deviation. This precise guidance ensures the timeliness and accuracy of opening and closing the vents 4111, making the air pressure regulation within the air cylinder assembly 2 more efficient and reliable. Meanwhile, the vents 4111, which are spaced around the guide hole 4112, can evenly allow gas to enter and exit when the inner core 42 moves, further optimizing the air pressure balance and improving the overall performance of the ball gun.

[0030] In some possible implementations, the inner core body 421 has a cover plate 4211 and a cross rib 4212 connecting the cover plate 4211. The first elastic component 5 is a spring, sleeved on the cross rib 4212 and abutting against the cover plate 4211, which is used to close or open the vent 4111. The design of the cross rib 4212 not only enhances the structural strength of the inner core 42, making it more stable and less prone to deformation or damage when subjected to air pressure changes and the force of the elastic component, but also provides convenient and stable support for the installation of the spring. The spring sleeved on the cross rib 4212 can evenly apply elastic force to the cover plate 4211, ensuring that the cover plate 4211 has good sealing performance when closing the vent 4111 and can move quickly and smoothly when it is necessary to open the vent 4111. This structural design makes the fit between the inner core 42 and the first elastic component 5 tighter and more reliable, improving the working stability and durability of the entire abutting component 4.

[0031] In some possible implementations, the piston rod 3 includes a main rod body 31 and a mating rod 32. The main rod body 31 extends along the length of the air cylinder assembly 2, providing stable support and guidance for the movement of the piston 10, ensuring that the piston 10 can move accurately in a straight line within the air cylinder assembly 2. The mating rod 32 is connected to the end of the main rod body 31 and engages with the movable locking member 9 for a limiting engagement. This structural design allows the sliding member 8 to effectively drive the mating rod 32 and the entire piston rod 3 to move through the movable locking member 9 when moving, achieving precise control over the movement of the piston 10. At the same time, the limiting engagement between the mating rod 32 and the movable locking member 9 also ensures a stable and reliable connection between the two during sliding, preventing loosening or detachment, thereby ensuring the smooth operation of the launch process.

[0032] In some possible implementations, the slider 8 has a slider 81 and a sliding frame 82. The slider 81 is located on the outer surface of the gun housing 1, allowing the user to operate it manually and push the slider 8 along the outer surface of the gun housing 1. The sliding frame 82 is located inside the gun housing 1 and is connected to the slider 81, moving synchronously inside the gun housing 1 under the action of the slider 81. A stop rib 821 is provided on the sliding frame 82, providing a limit and support for the rotation of the movable latching member 9. The movable latching member 9 is rotatably mounted on the sliding frame 82, and a third elastic member 11 is provided between the movable latching member 9 and the sliding frame 82. Under the action of the third elastic member 11, the movable latching member 9 rotates to abut against the stop rib 821. At this time, the movable latching member 9 and the cooperating rod 32 are in a limited engagement state, which can drive the piston rod 3 to move together. When the sliding frame 82 moves to the point where the movable latching member 9 contacts the release frame 7, the release frame 7 pushes the movable latching member 9 to rotate, causing the movable latching member 9 to release the cooperating rod 32 and release the limit on the piston rod 3. This structural design makes the cooperation between the slider 8, the movable latch 9, and the release bracket 7 more flexible and reliable, realizing automated control of the launch process.

[0033] In some possible implementations, a fixed shaft 822 is provided on the sliding frame 82. The movable latching member 9 has a swing engagement part 91, a latching part 92, and a central hole 93. The central hole 93 is located between the swing engagement part 91 and the latching part 92, and is rotatably fitted onto the fixed shaft 822. This structural design allows the movable latching member 9 to rotate flexibly around the fixed shaft 822, realizing the limiting engagement and release functions of the latching part 92 and the engagement rod 32. When the sliding member 8 moves towards the tail of the gun case 1, the latching part 92, under the action of the third elastic component 11, tightly engages with the engagement rod 32, driving the limiting engagement rod 32 to move together. When the sliding frame 82 moves to its limit position, the release frame 7 pushes the swing engagement part 91, causing the movable latching member 9 to rotate around the fixed shaft 822, and the latching part 92 moves away from the engagement rod 32, completing the release action. This rotating latching and release structure is ingeniously designed, easy to operate, and can ensure the accuracy and stability of the firing process.

[0034] In some possible implementations, the release frame 7 includes a plate 71 and a protrusion 72 disposed on the plate 71. The protrusion 72 extends along the thickness direction of the plate 71. When the sliding frame 82 moves to its limit position, the protrusion 72 can accurately push against the swing engagement part 91 of the movable latching member 9, triggering the movable latching member 9 to rotate and release the engagement rod 32. The plate 71 is connected to the gun housing 1 by fasteners, and the connection is firm and reliable, capable of withstanding the reaction force generated when the movable latching member 9 rotates, ensuring the stability of the release frame 7 during operation. This structural design allows the release frame 7 to precisely control the release timing of the movable latching member 9, thereby ensuring the smooth conduct of the firing process.

[0035] In some possible implementations, the release frame 7 is provided with support protrusions 73 on both sides along its thickness direction. The two support protrusions 73 abut against the inner surfaces of two shell walls sequentially arranged along the thickness direction of the gun housing 1, providing stable support for the release frame 7 and enhancing its fixation within the gun housing 1. When the movable locking member 9 rotates to release the engaging rod 32, the release frame 7 experiences a certain reaction force. The support protrusions 73 effectively disperse and bear these forces, preventing displacement or deformation of the release frame 7, ensuring the fitting accuracy between the release frame 7 and the movable locking member 9, thereby improving the overall reliability and service life of the ball gun.

Clearly, many modifications and variations can be made based on the content of this specification.
