Description

Technical Field

[0001] This utility model relates to the field of nail gun noise reduction technology, and in particular to a noise reduction device for nail guns and a nail gun. Background Technology

[0002] A nail gun is a fastening tool that uses compressed air to propel nails at high speed into objects. It allows for rapid, continuous operation and is highly efficient, labor-saving, and precise, making it widely used in woodworking and construction. However, pneumatic nail guns rely on the instantaneous release of compressed air, generating 80-100 decibels of noise during operation, which can exceed 100 decibels in open working environments. Prolonged continuous use may cause hearing damage for workers; furthermore, it can disturb residents in residential areas.

[0003] Existing noise reduction devices are directly fixed to the tail of the nail gun. Different models of nail guns require noise reduction devices of corresponding sizes, resulting in poor versatility and high operating costs. In addition, the filling material inside the noise reduction device is prone to accumulating explosion residue or dust over long-term use, affecting the noise reduction effect. Frequent disassembly and cleaning are required, making maintenance inconvenient. Utility Model Content

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] like Figures 1 to 3 As shown, this embodiment provides a noise reduction device for a nail gun, located on the top 101 of the nail gun body 100. The nail gun body 100 has a drive chamber and an exhaust chamber. The drive chamber converts the potential energy of compressed air into mechanical kinetic energy, driving a piston to fire the nail. The exhaust chamber releases residual air pressure from the drive chamber, helping the piston to reset and prepare for the next firing. (Refer to...) Figure 2 The top 101 of the nail gun body 100 has a fixing hole 102, which is connected to the exhaust chamber.

[0044] The noise reduction device includes a base 1, a fixing cylinder 2, and sound-absorbing filler 3. The base 1 is detachably mounted on the top 101 and has a through hole 11, which is directly opposite the fixing hole 102 and connects to the exhaust chamber. The fixing cylinder 2 is detachably mounted on the base 1 and has multiple vent holes 21 spaced apart circumferentially. The fixing cylinder 2 surrounds an installation chamber, which is connected to the through hole 11. The sound-absorbing filler 3 is placed inside the installation chamber. The residual air pressure in the exhaust chamber passes through the fixing hole 102 and the through hole 11 in sequence, enters the installation chamber, is treated by the sound-absorbing filler 3, and is then discharged through the multiple vent holes 21 to reduce noise levels and noise pollution, thereby preventing hearing damage to workers. In addition, since the noise reduction device adopts a split installation structure, it can be modularly replaced. Different models of nail gun body 100 only need to replace the corresponding model of base 1, while the fixing cylinder 2 and sound-absorbing filling material 3 are all interchangeable, which has high versatility and good economic benefits. Furthermore, the device has a simple structure, is easy to process and install, and is also very convenient for later maintenance.

[0045] Specifically, the sound-absorbing filler 3 is a sound-absorbing cotton that has been disclosed in the prior art. The sound-absorbing cotton is made of existing materials, such as polyester fiber cotton, melamine foam or glass wool, etc. The specific material composition refers to the prior art, and will not be specifically limited or elaborated here, as long as it can achieve the effect of sound absorption and noise reduction.

[0046] Optionally, the base 1 has multiple through holes 11 spaced apart, each through hole 11 communicating with the fixing hole 102 and the mounting chamber. This arrangement allows the residual air pressure in the exhaust chamber to quickly enter the mounting chamber, thereby achieving rapid noise reduction.

[0047] Specifically, in this embodiment, four through holes 11 are provided; in other embodiments, the specific number of through holes 11 can be set as needed, and no specific limitation is made here.

[0048] Optionally, the shape of the sound-absorbing filler 3 is adapted to the shape of the installation chamber, and the sound-absorbing filler 3 abuts against the inner wall of the installation chamber to maximize the contact area between the residual air pressure and the sound-absorbing filler 3, thereby improving the noise reduction effect of the sound-absorbing filler 3.

[0049] Specifically, in this embodiment, both the mounting chamber and the sound-absorbing filler 3 are columnar; in other embodiments, the mounting chamber and the sound-absorbing filler 3 may also be cuboid or other shapes, which are not specifically limited here.

[0050] Optionally, a shock-absorbing pad is provided between the base 1 and the top 101 of the nail gun body 100. On the one hand, the shock-absorbing pad can prevent the high-frequency vibration generated when the nail gun is working from being transmitted to the noise reduction device, which is beneficial to improving the service life of the noise reduction device; on the other hand, it can also prevent the vibration of the nail gun body 100 from causing resonance between the noise reduction device and the nail gun body 100, thus avoiding the generation of additional noise.

[0051] For example, the shock-absorbing pad is a rubber pad, which has the advantages of stable cushioning effect, wear resistance, low cost, easy replacement and maintenance, and safety and environmental protection.

[0052] Optionally, the base 1 and / or the fixing cylinder 2 are made of stainless steel, preferably AISI 415 or S41500. The manganese and silicon elements in AISI 415 stainless steel enhance its toughness, while the combination of chromium, silicon and manganese in S41500 improves its impact resistance and deformation resistance. Both have good shock resistance, which helps to extend the service life of the noise reduction device.

[0053] Optionally, such as Figure 2 and Figure 3 As shown, the noise reduction device also includes multiple fasteners 4. The top 101 of the nail gun body 100 has multiple fastening holes 103, which are spaced apart circumferentially along the fixing holes 102. The base 1 has multiple first connecting holes 12 spaced apart circumferentially, and the fixing cylinder 2 has multiple second connecting holes 22 spaced apart circumferentially. The fasteners 4, fastening holes 103, first connecting holes 12, and second connecting holes 22 correspond one-to-one. The fasteners 4 pass through the second connecting holes 22 and the first connecting holes 12 in sequence, and are fixed in the fastening holes 103 by screwing, thus installing the noise reduction device on the top 101 of the nail gun body 100. Installation and disassembly are convenient and quick, improving assembly efficiency and facilitating later maintenance.

[0054] Specifically, the fastener 4 is a bolt commonly used in this field, the fastening hole 103 is a threaded hole, and the first connecting hole 12 and the second connecting hole 22 are both through holes 11.

[0055] For example, in this embodiment, four fasteners 4, four fastening holes 103, four first connecting holes 12 and four second connecting holes 22 are provided; in other embodiments, the number of fasteners 4, four fastening holes 103, four first connecting holes 12 and four second connecting holes 22 can be set as needed, and no specific limitation is made here.

[0056] Furthermore, the fastener 4 is provided with a tightening part 41, which allows for manual tightening without the need for any tools, making the operation simpler and more convenient. The tightening part 41 is provided with an anti-slip structure, specifically, the anti-slip structure is an anti-slip pad, such as a rubber pad; or, the anti-slip structure is an anti-slip protrusion, which can be dot-shaped protrusions or textured protrusions of any shape, as long as it can increase the contact friction between the operator's hand and the tightening part 41. The specific form is in accordance with the prior art, and is not specifically limited in this embodiment.

[0057] In addition, this embodiment also provides a nail gun, including a nail gun body 100 and the above-mentioned noise reduction device, which has all the beneficial effects of the above-mentioned noise reduction device, and will not be described in detail here.

[0058] Example 2

[0059] This embodiment provides a noise reduction device for nail guns, which differs from Embodiment 1 in that:

[0060] In this embodiment, the noise reduction device further includes multiple first fasteners and multiple second fasteners. The top 101 of the nail gun is provided with multiple first fastening holes, which are spaced apart circumferentially along the fixing hole 102. The base 1 is provided with multiple first connecting holes spaced apart circumferentially. Each first fastener, first fastening hole, and first connecting hole corresponds to the first fastener, and the first fastener passes through the first connecting hole and is fixed to the first fastening hole by screwing. The base 1 is provided with multiple second fastening holes spaced apart circumferentially, and the fixing cylinder 2 is provided with multiple second connecting holes spaced apart circumferentially. Each second fastener, second fastening hole, and second connecting hole corresponds to the second fastener, and the second fastener passes through the second connecting hole and is fixed to the second fastening hole by screwing. With this configuration, the base 1 can be detachably installed on the top 101 of the nail gun body 100, and the fixing cylinder 2 can be detachably installed on the base 1, allowing for separate disassembly and installation of either the base 1 or the fixing cylinder 2, making installation, disassembly, and subsequent maintenance more convenient and faster.

[0061] Specifically, the fixing cylinder 2 and the sound-absorbing filler 3 can be installed on the base 1 first using the second fastener, and then the base 1 can be installed on the top 101 of the nail gun body 100 using the first fastener. The sound-absorbing filler 3 will wear out with long-term use of the nail gun. When it is necessary to replace the sound-absorbing filler 3, the sound-absorbing filler 3 can be removed simply by disassembling the fixing cylinder 2, making the operation simpler and more convenient.

[0062] For example, both the first fastener and the second fastener are bolts, both the first fastening hole and the second fastening hole are threaded holes, and both the first connecting hole and the second connecting hole are through holes 11. In addition, the number of the first fastener, the first fastening hole, the first connecting hole, the second fastener, the second fastening hole, and the second connecting hole can be set as needed, and no specific limitation is made here.

[0063] Furthermore, the first fastener and / or the second fastener are provided with a screwing part, which can be screwed on manually without the need for any tools, making the operation simpler and more convenient.

[0064] The screwing part is provided with an anti-slip structure. Specifically, the anti-slip structure is an anti-slip pad, such as a rubber pad; or, the anti-slip structure is an anti-slip protrusion, which can be dot-shaped protrusions or textured protrusions of any shape, as long as it can increase the contact friction between the operator's hand and the screwing part. The specific form is in accordance with the prior art and is not specifically limited in this embodiment.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
