Description

Technical Field

[0001] The utility model relates to an internal component of a toy gun, in particular to an automatic gearbox component for a toy gun. Background Art

[0002] The core components of existing toy guns mainly include: a driving component, a pneumatic component, a bullet pushing component, a trigger, and a magazine. Among them, the bullet firing and the reset standby of each component are mainly achieved through the cooperation of the driving component, the pneumatic component, and the bullet pushing component. As Figure 1 shown, a power transmission is mainly carried out through a set of drawbridges 14 among these three components, and a drawbridge spring 15 is used to achieve reset. However, during use, since the drawbridge needs to move back and forth frequently and also needs to maintain balance and relative fixation, a lot of auxiliary parts need to be arranged at the adjacent positions of the gun shell and other components. Not only are these auxiliary parts easy to damage, but also the drawbridge is prone to break due to the length, shape, and structural relationship, thus causing the entire gun to be unusable. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an automatic gearbox component for a toy gun. By improving the structures of the driving component, the pneumatic component, and the bullet pushing component, the drawbridge, the drawbridge spring, and related auxiliary parts are cancelled, so as to improve the stability and durability of the toy gun and its practical value.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] An automatic gearbox component for a toy gun includes a driving component, a pneumatic component, and a bullet pushing component. The driving end of the driving component is connected to the driving end of the pneumatic component; the bullet pushing component includes a gas pushing piston, a nozzle pushing piston, a BB bullet nozzle, a nozzle reset spring, and a nozzle clamping rubber ring. The nozzle clamping rubber ring is arranged on the inner wall of the middle part of the gas pushing piston. The BB bullet nozzle is movably connected with the nozzle pushing piston in a "cross" structure. The nozzle reset spring is arranged between one end of the BB bullet nozzle and the nozzle pushing piston. A detachable clamping connection is formed between the other end of the BB bullet nozzle and the nozzle clamping rubber ring; the exhaust end of the pneumatic component is connected to the gas pushing piston.

[0006] Further, the pneumatic component includes a toy gun housing, a piston chamber, a piston push rod, a piston rod rack, and a power spring. The piston chamber is disposed within the toy gun housing. The air-pushing piston is located within the piston chamber. One end of the piston push rod is fixedly connected to one end of the air-pushing piston, and a power spring is disposed between the other end of the piston push rod and the inner wall of the toy gun housing. The other end of the air-pushing piston is connected to the bullet-pushing assembly. The piston rod rack is disposed on the lower side of the piston push rod and meshes with the driving end of the driving assembly. The central axes of the power spring, the piston push rod, and the air-pushing piston are on the same straight line, and the piston push rod and the air-pushing piston can move freely along the telescopic direction of the power spring.

[0007] Still further, the driving assembly includes a driving half gear, a transmission gear, and a gear driving motor. The driving half gear, the transmission gear, and the gear driving motor are all mounted on the inner wall of the toy gun housing. The driving teeth of the gear driving motor mesh with the transmission gear. The driving teeth of the transmission gear mesh with the driving half gear. The driving teeth of the driving half gear mesh with the piston rod rack.

[0008] Even further, a through hole for one end of the BB bullet nozzle to pass through is formed in the center of the nozzle piston. A limiting step is provided on the inner wall of the through hole. The diameter of the end of the BB bullet nozzle that does not pass through the nozzle piston is greater than the diameter of the central through hole of the nozzle piston, so as to form a space with two-end limitation and freely variable length between the nozzle piston and the limiting step of the through hole. The nozzle return spring is disposed within this space and drives the BB bullet nozzle to move freely along the central axis direction of the through hole.

[0009] Compared with the prior art, the present utility model has the following beneficial effects:

[0010] (1) The present utility model eliminates the drawbridge, the drawbridge spring and related components, solves the problems in the prior art that the components are easily damaged and the toy gun cannot be used due to the breakage of the drawbridge, thereby improving the stability and durability of the toy gun, increasing the service life, and greatly improving the market value of the toy gun.

[0011] (2) The present utility model solves the reset problem of related components by providing a nozzle return spring in the bullet-pushing assembly. At the same time, the physical structure of the nozzle piston itself is used to limit the movement space and movement direction of the nozzle return spring, so as to achieve the purpose of protecting the nozzle return spring without adding components, making the overall structure of the toy gun more compact and stable, the performance more stable, greatly reducing the failure rate, and reducing the prone failure points.

[0012] (3) The present utility model comprehensively optimizes the overall structure and transmission method of the drive assembly, pneumatic assembly, and bullet pushing assembly, making the toy gun smaller in size, faster in transmission, and lower in energy consumption. According to experimental statistics, compared with before improvement, the shooting speed of the improved toy gun is increased by 25%, the energy consumption is reduced by 10%, the service life is increased by 20%, the overall cost of the gun is reduced by 15%, and the market competitiveness is greatly improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below in conjunction with the drawings and specific embodiments. The illustrative embodiments and descriptions of the present utility model are used to explain the present utility model, but do not limit the present utility model.

[0020] As Figures 2-5 shown: The present utility model includes a drive assembly, a pneumatic assembly, and a bullet pushing assembly. The drive end of the drive assembly is connected to the drive end of the pneumatic assembly, and the exhaust end of the pneumatic assembly is connected to the bullet pushing assembly.

[0021] Among them, the pneumatic component includes a toy gun housing 1, a piston chamber 2, a piston push rod 3, a gas-pushing piston 4, a piston rod rack 9, and a power spring 10. The piston chamber 2 is arranged inside the toy gun housing 1. One end of the piston push rod 3 is fixedly connected to one end of the gas-pushing piston 4. The gas-pushing piston 4 is located inside the piston chamber 2 and can move. The other end of the gas-pushing piston 4 is connected to the ammunition pushing component. The piston rod rack 9 is fixedly arranged on the lower side of the piston push rod 3. The piston rod rack 9 is connected to the driving end of the driving component. The power spring 10 is arranged between the other end of the piston push rod 3 and the inner wall of the toy gun housing 1.

[0022] The driving component includes a driving half gear 11, a transmission gear 12, and a gear driving motor 13. The driving half gear 11, the transmission gear 12, and the gear driving motor 13 are all rotatably connected to the inner wall of the toy gun housing 1. The driving teeth of the gear driving motor 13 are meshed with the transmission gear 12. The driving teeth of the transmission gear 12 are meshed with the driving half gear 11. The driving teeth of the driving half gear 11 are meshed with the piston rod rack 9.

[0023] The ammunition pushing component includes a gas-pushing piston 4, a nozzle piston 5, a BB bullet nozzle 6, a nozzle return spring 7, and a nozzle clamping rubber ring 8. The nozzle clamping rubber ring 8 is arranged on the inner wall of the middle part of the gas-pushing piston 4. The BB bullet nozzle 6 passes through the middle part of the nozzle piston 5 and can move. The nozzle return spring 7 is arranged between the BB bullet nozzle 6 and the nozzle piston 5. One end of the BB bullet nozzle 6 is detachably clamped and connected to the nozzle clamping rubber ring 8. The other end of the BB bullet nozzle 6 is connected to the ammunition feeding mechanism of the toy gun.

[0024] Specifically, a through hole for one end of the BB bullet nozzle 6 to pass through is opened in the center of the nozzle piston 5. A limiting step is arranged on the inner wall of the through hole. The diameter of the end of the BB bullet nozzle 6 that does not pass through the nozzle piston 5 is larger than the diameter of the central through hole of the nozzle piston 5, so as to form a space with limited ends and a freely variable length between it and the limiting step of the through hole. The nozzle return spring 7 is arranged in this space and drives the BB bullet nozzle 6 to move freely along the center line direction of the through hole.

[0025] The working principle of the present utility model is as follows:

[0026] When the utility model is in use, the gear-driven motor 13 rotates counterclockwise, driving the transmission gear 12 to rotate clockwise. The transmission gear 12 drives the driving half gear 11 to rotate counterclockwise. The gear of the driving half gear 11 meshes with the piston rod rack 9, driving the piston push rod 3 to move backward, compressing the power spring 10 to store energy. While the piston push rod 3 moves backward, it drives the air-pushing piston 4 to move in the piston chamber 2. Since the middle part of the air-pushing piston 4 is provided with a nozzle clamping rubber ring 8, it pulls 6 to move backward, so that the end of the BB bullet nozzle 6 contacts the BB bullet at the BB bullet ejection port located at the end of the BB bullet nozzle 6. Since the BB bullet nozzle 6 compresses the nozzle return spring 7 when moving backward, the nozzle return spring 7 ejects the BB bullet into the ballistic through the BB bullet nozzle 6 when resetting. When the piston push rod 3 moves a certain distance, since the BB bullet nozzle 6 and the nozzle clamping rubber ring 8 are clamped, after the BB bullet nozzle 6 compresses the nozzle return spring 7, the air-pushing piston 4 and the BB bullet nozzle 6 are separated. The piston push rod 3 continues to move. Since the teeth of the driving half gear 11 are not complete, when moving to the end, the piston push rod 3 pushes the gas in the piston chamber 2 out from the BB bullet nozzle 6 under the action of the power spring 10, thus completing the firing of the BB bullet. In the prior art, an additional mechanism is required to push the BB bullet nozzle 6 backward to eject the BB bullet, which is not only prone to failure but also has a low service life. The cooperation of the nozzle clamping rubber ring 8 and the air-pushing piston 4 and the connection with the BB bullet nozzle 6 not only do not require an additional mechanism but also have a tight connection and a low failure rate.

[0027] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present invention, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
