[0001] This utility model relates to the field of nail shooting technology, and in particular to a silent nail shooting method. Background Technology

[0002] Gunpowder-driven nail guns are widely used in construction and decoration to quickly drive nails into hard substrates such as concrete and steel plates. Traditional nail gun structures typically consist of a connecting sleeve (containing the propellant), the nail body, and a fixing sleeve. However, in practical applications, they suffer from the following drawbacks: Insufficient sealing: During firing, the propellant gas easily leaks from the gap between the barrel and the nail, leading to reduced nail penetration and increased noise; Difficult ejection: After firing, the connecting sleeve and nail body often become stuck together, requiring manual separation and reducing construction efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a silent nail gun.

[0004] The purpose of this utility model is achieved through the following technical solution: a silent nail, comprising a connecting sleeve, a nail body, and a fixing sleeve, wherein the tail end of the connecting sleeve is provided with a filling cavity, the filling cavity is filled with propellant, and the tail end of the nail body is connected to the head end of the connecting sleeve; the fixing sleeve is provided with an annular groove, the inner side of the annular groove forms an annular platform, a gasket is provided on the annular platform, the gasket is provided with a sliding hole, and the nail body is slidably connected to the sliding hole.

[0005] Specifically, the nail body and the connecting sleeve are integrally injection molded.

[0006] Specifically, the front end of the connecting sleeve forms a connecting cavity, the tail end of the nail body is placed in the connecting cavity, and the end face of the connecting sleeve is provided with an annular limiting platform to limit the tail end of the nail body in the connecting cavity.

[0007] Specifically, the gasket has a groove on the side opposite to the connecting sleeve.

[0008] Specifically, a tapered through hole is provided at the center of the ring platform.

[0009] Specifically, the fixing sleeve and the gasket are connected together by integral injection molding.

[0010] This utility model has the following advantages:

[0011] The annular groove of the fixed sleeve fits tightly with the launcher barrel, and the gasket is embedded in the barrel to form a sealed space, reducing gas leakage, significantly improving the initial velocity and penetration of the nail, while reducing firing noise.

[0012] The end face of the gasket is provided with a groove and an annular ejection platform. When firing, the tail of the nail body is inserted into the groove, and the ejection platform abuts against the end face of the connecting sleeve. Under the thrust of the gunpowder, the nail body and the connecting sleeve are forcibly separated, realizing automatic ejection after firing and improving construction efficiency.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0020] like Figures 1 to 2 As shown, a silent nail includes a connecting sleeve 1, a nail body 2, and a fixing sleeve 3. The tail end of the connecting sleeve 1 is provided with a propellant filling cavity 5, which is filled with propellant. The tail end of the nail body 2 is connected to the head end of the connecting sleeve 1. The fixing sleeve 3 is provided with an annular groove 6, and an annular platform is formed on the inner side of the annular groove 6. A gasket 4 is provided on the annular platform, and the gasket 4 is provided with a sliding hole. The nail body 2 is slidably connected to the sliding hole. The fixing sleeve 3 and the gasket 4 are integrally injection molded together. In this embodiment, during use, the connecting sleeve 1 and the nail body 2 are inserted into the barrel of the launcher. At this time, the barrel of the launcher is inserted into the annular groove 6 of the fixing sleeve 3, and the gasket 4 is also located inside the barrel of the launcher. This can make the space inside the barrel highly sealed. When the launcher ignites the propellant, the propellant explodes and pushes the nail body 2 out of the barrel. Since the annular groove 6 of the fixing sleeve 3 cooperates with the barrel, the sealing of the barrel is enhanced. This can increase the speed of the nail body and reduce the noise generated during the firing of the nail. The fixing sleeve 3 is installed on the wall by the cooperation of the gasket 4 and the nail body 2. In this way, the items to be installed can be installed on the fixing sleeve 3.

[0021] Furthermore, the nail body 2 and the connecting sleeve 1 are integrally injection molded and connected; the front end of the connecting sleeve 1 forms a connecting cavity, the tail end of the nail body 2 is placed in the connecting cavity, and the end face of the connecting sleeve 1 is provided with an annular limiting platform to limit the tail end of the nail body within the connecting cavity. In this embodiment, the nail body 2 is a metal part, the connecting sleeve 1 is a plastic part, and the tail end of the nail body 2 is embedded in the connecting cavity and integrally formed with the connecting sleeve 1.

[0022] Furthermore, a groove 9 is provided on the side of the gasket 4 opposite to the connecting sleeve 1, and an annular ejection platform 7 is provided on the end face of the gasket 4 at the outer periphery of the groove 9. In the prior art, after the nail is fired, the connecting sleeve 1 and the nail body 2 are difficult to separate, requiring construction personnel to handle them one by one, which is cumbersome. In this embodiment, by providing a groove 9 on the gasket 4, the inner diameter of the groove 9 is the same as the outer diameter of the tail of the nail body 2. In this way, when the nail body 2 is fired, the tail of the nail body 2 is inserted into the groove 9, and a cutting edge is formed between the inner wall of the groove 9 and the top surface of the gasket 4. When the tail of the nail body 2 is inserted into the groove 9, the cutting edge cuts the connecting sleeve 1 to separate it from the nail body 2. This facilitates the detachment of the connecting sleeve 1 without the need for additional separation, saving labor and effort.

[0023] Furthermore, a conical through hole 8 is provided at the center of the ring platform. In this embodiment, the conical through hole 8 can collect the debris generated when the nail 2 is inserted into the wall, thus preventing debris from accidentally injuring the operator.

[0024] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
