Description

Technical Field

[0001] This utility model relates to a cartridge wheel assembly for easy loading of cartridges, belonging to the field of air gun technology. Background Technology

[0002] An air gun is a firearm that uses high-pressure gas to fire bullets. To achieve continuous firing, a cartridge assembly is used to load bullets. Existing cartridge assemblies include a cartridge base, a cartridge wheel, and a return spring. The cartridge wheel is mounted on the cartridge base, and cartridge holes are distributed along the circumference of the cartridge wheel. The return spring is installed inside the cartridge base and drives the cartridge wheel to rotate. To facilitate loading and allow the cartridge wheel to rotate precisely at a specific angle so that each rotation ensures accurate alignment of the cartridge holes with the loading port, designs such as CN202320 have been developed. An automatic cartridge assembly disclosed in 335081.5 uses a lever attached to the cartridge base, which forms a ratchet mechanism with the cartridge, causing the cartridge to move intermittently in one direction. This mechanism allows the cartridge assembly to rotate at one degree angle each time. For example, in a pull-down air gun structure with a cartridge wheel disclosed in CN202320335104.2, the connecting mechanism on the gun body that cooperates with the cartridge assembly must cooperate with both the lever and the tooth groove of the cartridge wheel, resulting in a complex structure and easy misalignment during use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a convenient spring wheel assembly, which can achieve accurate spring loading through a simple linkage mechanism, thus overcoming the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a convenient spring wheel assembly, including a spring wheel base, a spring wheel, and a return spring. The spring wheel is rotatably connected to the spring wheel base. Multiple spring wheel holes are evenly distributed along the upper edge of the spring wheel, and the same number of tooth grooves as the spring wheel holes are evenly distributed on the outer circumference of the spring wheel. The return spring is installed in the spring wheel base and can drive the spring wheel to rotate. It includes an elastic element one, an elastic element two, a pawl and a paddle rotatably connected to the spring wheel base. The paddle is connected to the pawl and engages with the tooth grooves of the spring wheel to resist. The elastic element one has an elastic force that drives the pawl to rotate away from the spring wheel. The elastic element two has an action force that drives the paddle to rotate in the same direction as the pawl. Under this action force, the paddle can push the pawl to rotate towards the spring wheel, so that the pawl and the spring wheel form a ratchet mechanism. When the paddle rotates in the opposite direction under the action of an external force that overcomes the action force of the elastic element two and engages with the spring wheel to resist, the pawl rotates to a position separated from the spring wheel. After the external force is removed, the paddle returns to the position separated from the spring wheel, and the pawl returns to the position where it forms a ratchet mechanism with the spring wheel.

[0005] By implementing this utility model, in the absence of external force, the pawl is pushed by the paddle and engages with the tooth groove of the cartridge wheel to form a ratchet mechanism. At this time, the cartridge wheel assembly can rotate one notch each time during loading, causing the return spring to deform and generate a spring force that pushes the cartridge wheel to reverse. After the cartridge wheel assembly loaded with bullets is installed on the gun body, the external force that overcomes the force of the elastic element acts on the paddle, causing the paddle to rotate and block the cartridge wheel. During the process of the pawl rotating to the position where it is separated from the cartridge wheel, the cartridge wheel rotates a certain angle under the action of the return spring. After the external force is removed, when the paddle returns to the position where it is separated from the cartridge wheel and the pawl returns to the position where it forms a ratchet mechanism with the cartridge wheel, the pawl has already blocked the next tooth groove, realizing the control of the cartridge wheel rotation angle to complete the loading. Therefore, it is only necessary to set a linkage mechanism to push the paddle to rotate on the gun body, so that the paddle can accurately load bullets by reciprocating. Attached Figure Description

[0008] The figure shows: 1. Spring wheel base; 2. Spring wheel; 4. Pawl; 5. Paddle. Detailed Implementation

[0009] Embodiments of this utility model: such as Figure 1 As shown, a convenient spring assembly includes a spring base 1, a spring 2, and a return spring. The spring 2 is mounted on the spring base 1. Multiple spring holes are evenly distributed along the upper edge of the spring 2, and the same number of toothed grooves are evenly distributed on the outer circumference of the spring 2 as the spring holes. The return spring is installed inside the spring base 1 and can drive the spring to rotate. This application includes an elastic element one, an elastic element two, a pawl 4 mounted on the spring base 1, and a paddle 5. The paddle 5 is V-shaped, with its upper end connected to the pawl 4 and its lower end engaging with the toothed grooves of the spring 2 to abut. The elastic element one, elastic element two, pawl 4, and paddle 5 are mounted on the spring base 1. Both components are torsion springs. Elastic component one has a force that drives the pawl 4 to rotate clockwise, thus moving it away from the magazine wheel 2. Elastic component two has a force that drives the paddle 5 to rotate clockwise. Under the force of elastic component two, paddle 5 pushes the pawl 4 to rotate counterclockwise, engaging with the teeth on the magazine wheel 2 to form a ratchet mechanism. During loading, the magazine wheel 2 rotates counterclockwise, rotating a specific angle each time through its engagement with the pawl 4 until loading is complete. During this process, the return spring deforms, generating a force that pushes the magazine wheel to rotate clockwise. After the loaded magazine wheel assembly is installed on the gun body, as... Figure 2 As shown, when the loading mechanism of the gun body pushes the lever 5 to rotate counterclockwise, it releases the force on the pawl 4. Under the action of the elastic element, the pawl 4 rotates clockwise and separates from the magazine 2. The lower end of the lever 5 will abut against the tooth groove of the magazine 2. During this process, the magazine 2 rotates clockwise through a certain angle under the action of the return spring. After the loading mechanism separates from the lever 5, as shown... Figure 1 As shown, under the action of the elastic element 2, the paddle 5 is reset to the position separated from the spring wheel 2 and pushes the pawl 4 to reset to the position forming a ratchet mechanism with the spring wheel 2. Since the spring wheel 2 rotates clockwise by a certain angle under the action of the return spring, the pawl 4 cannot match the previous tooth groove and abuts against the next tooth groove. This allows the spring wheel 2 to rotate clockwise by one tooth groove angle for each reciprocating rotation of the paddle 5, which facilitates precise springing. Since the springing mechanism only needs to be connected to the paddle 5 to make it reciprocate, the structure of the springing mechanism can be very simple, achieving the effect of precise springing of the spring wheel assembly through a simple linkage mechanism.

The paddle is connected to the pawl and engages with the tooth groove of the spring wheel to resist it. The elastic element one has a spring force that drives the pawl to rotate away from the spring wheel. The elastic element two has a force that drives the paddle to rotate in the same direction as the pawl.

When the paddle rotates in the opposite direction to resist the spring wheel under the action of an external force that overcomes the force of the elastic element two, the pawl rotates to a position where it is separated from the spring wheel. After the external force is removed, the paddle returns to the position where it is separated from the spring wheel, and the pawl returns to the position where it forms a ratchet mechanism with the spring wheel.
