Bearing set pin

Abstract

To provide a set pin for use in an airsoft gun. [Solution] A small-diameter rotatable bearing 2 is built into the contact point 3 of the set pin with the cylinder. This reduces friction during cocking, achieving smooth operability and improved durability of parts, and resolving the issue of resistance and malfunctions during operation. This structure also has the advantage of being compatible with existing set pins, allowing for easy replacement.

Description

[Technical Field]

[0002] This invention relates to a cylinder release lever (hereinafter referred to as a set pin), which is a part used to lock and release the cylinder in an airsoft gun (especially a bolt-action airsoft rifle), and aims to improve operability and durability. [Background technology]

[0002] Conventionally, the set pin of an airsoft gun is made of a metal pin, which is prone to wear due to sliding and contact with the cylinder, causing resistance and sticking during operation. This has led to issues such as a shortened parts lifespan and complicated cocking operations. Summary of the Invention Problem to be solved

[0003] The purpose of this invention is to solve the above-mentioned problem of wear due to friction, to extend the life of parts, and to make the cocking operation smoother.

[0004] The set pin of this invention is constructed with a small rotatable bearing integrated into the end that contacts the cylinder, which reduces friction when the cylinder contacts the pin during cocking through rotational movement, allowing for smooth operation.

[0005] This bearing set pin has the same external shape as existing set pins, making it easy to replace existing set pins. In addition, this bearing set pin can be installed without changing the structure of existing airsoft guns, and functionality can be improved simply by replacing it with the existing set pin after disassembly.

[0006] This invention provides the following effects: -Reduced resistance during cocking operation, improving operability. Reduced wear caused by friction extends the life of the set pin and cylinder. -It is compatible with existing parts, so users can easily install it. [Brief explanation of the drawings]

[0007] [Figure 1] FIG. 2 is a side view of the bearing pin of the present invention with a bearing installed. [Figure 2] FIG. 2 is a cross-sectional view of the pin shown in FIG. 1, showing the arrangement of bearings provided on the pin body. DETAILED DESCRIPTION OF THE INVENTION

[0008] In this invention, it is desirable to use a thin-walled bearing for the built-in bearing, which ensures high durability and ease of processing, while also allowing for easy mass production and assembly, rather than using a thicker shaft. [Example]

[0008] The bearing pin for air guns of this invention is designed to have a bearing at the contact point with the cylinder of a bolt-action air gun. When in use, the air gun is disassembled, the conventional pin parts are removed, and then replaced with the bearing pin of this invention, and the gun is reassembled to its original state.

[0009] The bearing pin of this invention does not have a specified shape, but uses the part shape of existing products. Because it is compatible in size and shape, it can be easily replaced without requiring special processing or tools.

[0010] By implementing this invention in this way, friction between the cylinder and the pin is reduced, allowing for smooth cocking, and wear on the pin is suppressed, improving the durability of the parts and enabling stable operation over a long period of time.

Claims

[Claim 1] A set pin with a bearing for an airsoft gun is used to mechanically fix or release the bolt or cylinder of an airsoft gun, and is characterized in that a small-diameter rotatable bearing is built into the end of the set pin that comes into contact with the cylinder, thereby reducing friction during the cocking operation.
