Description

Technical Field

[0001] This utility model relates to the field of fastening tool technology, specifically to an improved nail fastener. Background Technology

[0002] A nail gun, also known as a fastener, is a tool that uses blank cartridges, gas, or compressed air as power to drive nails into a building structure. Compared to traditional methods such as pre-embedded fixing, drilling and pouring, bolting, and welding, it has advantages such as self-powered operation, rapid operation, reliable function, and cost savings: self-powered operation eliminates the burden of electrical wires and ductwork, facilitating on-site and high-altitude work; rapid operation shortens the construction period and reduces labor intensity; safety and reliability solve construction problems; and cost savings reduce construction costs. Therefore, it is widely used in building decoration and other fields.

[0003] When using a nail fastener, the firing pin moves rapidly forward within the chamber, its tip striking the tail of the integrated nail cartridge. This causes the cartridge to explode inside the nail tube, and the resulting gas propels the nail quickly into the front of the substrate, completing the nailing process. A drawback of nail fasteners is that the explosion of the nail cartridge inside the nail tube generates significant noise. This noise is directly transmitted into the environment, creating a sonic boom for construction workers and causing disturbance to residents. Therefore, a silencer is often installed on the nail tube to prevent injury to operators from the excessive noise.

[0004] In addition, during operation, the firing pin tube frequently enters the silencer in front of the nail gun. To ensure the explosive effect and improve the effectiveness of nail firing, the gaps between the components must be as small as possible to ensure the airtightness of the blast space. Moreover, since the internal components of the nail gun are mostly made of metal, the frequent interaction between the firing pin tube and the silencer inevitably leads to wear at the ends of the firing pin tube and the silencer, resulting in more and more metal shavings at their contact surfaces. As the metal shavings accumulate, they will affect the effectiveness of nail firing. Furthermore, when the nail gun is left unused for a long time, corrosion will occur on the contact surfaces between the firing pin tube and the silencer, which may even cause the contact surfaces to rust and become stuck, preventing normal operation. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an improved nail fastener that can minimize the friction between the firing pin tube and the silencer, prevent corrosion, and has excellent noise reduction and noise reduction performance.

[0006] To achieve the objectives of this utility model, the following technical solution is adopted: An improved pin fastener includes a front-end silencing section and a firing section connected to the silencing section. The silencing section includes a silencing and heat-insulating sleeve, with an external silencing sleeve fixedly connected to its front end. An external voltage regulator is fixedly connected to the external silencing sleeve and positioned in the middle of the silencing section. The front end of the firing pin tube extends into the hollow tube of the voltage regulator, which has multiple silencing holes. A fastening nut assembles and connects the external silencing sleeve, the external voltage regulator, and the voltage regulator. The silencing and heat-insulating sleeve includes an outer sleeve and an inner sleeve located inside the outer sleeve, forming a sealed silencing space between the outer and inner sleeves. The silencing holes communicate with the silencing space. The end of the voltage regulator that mates with the firing pin tube has an inclined inner surface, forming a flared structure with a certain length and a certain taper on the inner side of the end.

[0007] Preferably, the outer surface of the inner sleeve has a continuous raised structure, and a sound-absorbing channel is formed between adjacent raised structures.

[0008] Preferably, the protrusions are arranged in pairs and symmetrically on the outer surface of the inner sleeve, forming a sound-absorbing channel between the opposing protrusions.

[0009] More preferably, the raised structure is formed by a continuous series of raised ribs consisting of multiple ribs with regular and / or irregular shapes, forming a continuous sound-absorbing channel with reflective surfaces of different diameters, shapes, and angles between the opposing raised structures.

[0010] In a further preferred embodiment, the angle between the inclined surface of one end of the voltage regulating silencer and the firing pin tube is 5-15 degrees.

[0011] Preferably, the external silencing sleeve, the voltage regulating silencing device, and the external voltage regulator are all provided with silencing holes for noise propagation, and each has one or more boss structures on its outer peripheral surface.

[0012] More preferably, the nail fastener further includes a grip portion, which is connected to the firing portion to form a gun-shaped structure.

[0013] The beneficial effects of this utility model are that the improved nail fastener has multiple noise-reducing components on the front-end noise-reducing part, forming a multi-chamber, multi-stage noise reduction path with a long noise reduction channel, which significantly improves the noise reduction effect during the operation of the nail fastener and reduces noise pollution during operation; in addition, the end of the pressure regulating silencer that contacts the firing pin tube is set as an open structure with a certain taper, which significantly reduces the contact area between components and prevents the contact surfaces of the components from rusting or even rusting shut.

Detailed Implementation

[0015] To provide a better understanding of the purpose, structure, features and functions of this utility model, detailed descriptions are provided below with reference to the embodiments.

[0016] Combined with reference Figures 1-6 This invention provides a schematic diagram of an improved nail fastener according to an embodiment of the present invention. The nail fastener includes a front-end silencing section 10, a firing section 20 connected to the silencing section 10, and a grip section 30. The silencing section includes a silencing and heat-insulating sleeve 2, the front end of which is fixedly connected to an external silencing sleeve 3. An external pressure regulator 5 is fixedly connected to the inner part of the external silencing sleeve 3 via a threaded connection. A pressure regulator 4 is disposed in the middle of the silencing section 10. The front end of the firing pin tube 6 extends into the hollow tube of the pressure regulator 4. The pressure regulator 4 has multiple silencing holes 41. A fastening nut 1 assembles and connects the external silencing sleeve 3, the external pressure regulator 5, and the pressure regulator 4. In a preferred embodiment, the grip section is connected to the firing section to form a gun-shaped structure for easy operation.

[0017] See Figure 3 As shown, the sound-absorbing and heat-insulating sleeve 2 includes an outer sleeve 201 and an inner sleeve 202 disposed inside the outer sleeve. A sealed sound-absorbing space is formed between the outer sleeve 201 and the inner sleeve 202, and the sound-absorbing hole 41 communicates with the sound-absorbing space; as shown Figure 4As shown, continuous raised structures 203 are formed on the outer surface of the inner sleeve 202. The raised structures 203 are arranged in pairs and symmetrically on the outer surface of the inner sleeve 202, forming a noise-absorbing channel 204 between the opposing raised structures 203. The raised structures can be formed by multiple ribs of regular and / or irregular shapes in a continuous raised rib formation. In this way, a continuous noise propagation channel with different diameters, shapes and angles of reflective surfaces is formed between the opposing raised structures 203. On the one hand, the propagation length of the noise is extended, and on the other hand, the noise is eliminated through a complex reflection path.

[0018] See Figure 5 and Figure 6 In the nail fastener of this utility model, the inner surface of the end of the pressure regulating silencer 4 that cooperates with the firing pin tube 6 is set as an inclined surface, and a flared structure 42 with a certain length and a certain taper is formed on the inner side of the end. In this way, on the one hand, it is convenient for the end of the firing pin tube 6 to smoothly and repeatedly enter the pressure regulating silencer 4 to complete the nail firing action during the working process. On the other hand, more importantly, it can reduce the contact area between the end of the firing pin tube 6 and the pressure regulating silencer 4, significantly reduce the metal corrosion caused by friction, and prevent the nail fastener from rusting between the contact surfaces of the components due to long-term placement, which would cause the contact surfaces of the firing pin tube and the pressure regulating silencer to rust and become stuck.

[0019] In a preferred embodiment, the angle between the inclined surface of one end of the voltage regulating silencer 4 and the firing pin tube is 5-15 degrees.

[0020] In another preferred embodiment, the external silencing sleeve 3, the pressure regulating silencer 4, and the external pressure regulator 5 of this utility model are all provided with silencing holes for noise propagation, and each has one or more boss structures on its outer peripheral surface. In this way, multiple silencing chambers can be formed, so that the silencing effect can be gradually optimized in different chambers, enhancing the ability to reduce explosion noise, improving the silencing effect, and making the noise generated by the nail fastener during operation more effectively controlled, reducing noise pollution in the working environment, and creating relatively quiet and comfortable working conditions for operators.

[0021] This utility model discloses an improved nail fastener, which has multiple silencing components on the front silencing section to form a multi-chamber, multi-stage silencing path with a long silencing channel, significantly improving the noise reduction effect during the operation of the nail fastener and reducing noise pollution during operation. In addition, one end of the pressure regulating silencer that contacts the firing pin tube is set as an open structure with a certain taper, which significantly reduces the contact area between components and prevents the contact surfaces of the components from rusting or even rusting shut.

[0022] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
