A silent metal nail firing device

Abstract

This utility model discloses a silent metal nail firing device, including a nail gun. A first ring is fixedly connected to the nail gun, and a first fixing block is symmetrically fixedly connected to the first ring. A second ring is slidably connected to the nail gun, and a second fixing block is symmetrically fixedly connected to the second ring. A spring is fixedly connected between each first fixing block and each second fixing block. This utility model, by setting a first ring and a second ring connected to the machine body, allows the first ring to move closer to the second ring as the nail gun moves. Utilizing the spring force and the air resistance encountered when the guide rod slides within the sleeve, the excessively high firing rate of the nail gun is effectively reduced without affecting the working effect, thus significantly reducing noise and achieving a silent effect. Simultaneously, without compromising the working effect, the depth of the driven metal nail is appropriately reduced, facilitating subsequent removal.

Description

Technical Field

[0001] This utility model relates to the field of decoration equipment technology, and in particular to a silent metal nail firing device. Background Technology

[0002] A metal nail firing device typically refers to a nail gun. Nail guns use gunpowder or compressed air as power to drive nails directly into steel, concrete, or other substrates. They require no external power source or ventilation ducts and are suitable for high-altitude operations and on-site construction. Their firing principle is similar to that of a pistol, using the explosion of gunpowder or the release of energy through compressed air to propel a specially designed steel nail into the target.

[0003] Currently, nail guns are widely used due to their unique working mechanism, which allows metal nails to be firmly driven into the substrate and prevents them from falling out. However, the high-speed thrust generated by the combustion of gunpowder also brings some problems, especially high-frequency noise, which may cause hearing fatigue in workers and even damage their hearing with long-term use. If used in home renovations, such as for ceiling installation, the noise may also cause complaints from neighbors, especially during nighttime construction.

[0004] Furthermore, removing nails using a nail gun is extremely difficult. Because the nails are very firmly embedded, removal requires tools such as a cutting machine, which not only significantly increases the workload but may also damage the wall surface.

[0005] To address the above issues, we have developed a silent metal nail firing device. Utility Model Content

[0006] This utility model discloses a silent metal nail firing device, which aims to solve the technical problems in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A silent metal nail firing device includes a nail gun, a first ring fixedly connected to the nail gun, a first fixing block symmetrically fixedly connected to the first ring, a second ring slidably connected to the nail gun, a second fixing block symmetrically fixedly connected to the second ring, a spring fixedly connected between each of the first fixing blocks and the second fixing block, a sleeve fixedly connected inside each of the two second fixing blocks, and a spring penetrating one side of each of the two sleeves.

[0009] In a preferred embodiment, the sleeve has a first hole, a second hole, and the first hole communicates with the second hole. The sleeve also has a third hole, which communicates with the second hole.

[0010] In a preferred embodiment, a circular block is slidably connected inside the second hole, and a light rod is fixedly connected to the side of the circular block. The light rod passes through the first hole and is connected to the first fixed block.

[0011] In a preferred embodiment, a third fixing block is fixedly connected to the side of the second ring, and a bolt is rotatably connected inside the third fixing block. Threaded holes are equally spaced on the nail gun, and the threaded holes are threadedly connected to the bolt.

[0012] In a preferred embodiment, the nail gun has mounting holes fixedly connected to its side.

[0013] The silent metal nail firing device provided by this utility model has the following advantages:

[0014] Firstly, by setting up a first and second ring connected to the machine body, the first ring moves closer to the second ring as the nail gun moves. Utilizing the force of the spring and the air resistance encountered when the polished rod slides within the sleeve, the excessively high firing rate of the nail gun is effectively reduced without affecting its working effect, thus significantly reducing noise and achieving a silent operation. Simultaneously, without compromising working performance, the depth of the driven metal nail is appropriately reduced, facilitating subsequent removal.

[0015] Secondly, the operator can adjust the distance between the first and second rings by sliding the second ring, according to the required thickness of the nails for the nail gun, without affecting normal use. This adjusts the spring force and the air resistance encountered by the polished rod when sliding within the sleeve, thereby reducing noise to the point of silence. The entire process is simple and efficient. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] This utility model discloses a silent metal nail firing device.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a silent metal nail firing device includes a nail gun 1, a first ring 2 fixedly connected to the nail gun 1, a first fixing block 3 symmetrically fixedly connected to the first ring 2, a second ring 4 slidably connected to the nail gun 1, a second fixing block 5 symmetrically fixedly connected to the second ring 4, a spring 6 fixedly connected between a corresponding first fixing block 3 and a second fixing block 5, and a sleeve 7 fixedly connected inside each of the two second fixing blocks 5, with the spring 6 passing through one side of each of the two sleeves 7.

[0025] In this embodiment, the nail gun 1 is an existing device that uses gunpowder gas or compressed air to drive a piston to strike the nail, thereby embedding the nail into the substrate. This will not be described in detail here.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a first hole 8 is provided in the sleeve 7, a second hole 9 is provided in the sleeve 7, the first hole 8 and the second hole 9 are connected, and a third hole 10 is provided in the sleeve 7, the third hole 10 is connected to the second hole 9.

[0027] In this embodiment, it is particularly important to note that the size of the third hole 10 is smaller than that of the first hole 8, and the size of the first hole 8 is also smaller than that of the second hole 9. The purpose of this design is to allow outside air to smoothly enter the sleeve 7 through the third hole 10.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a circular block 11 is slidably connected inside the second hole 9, and a light rod 12 is fixedly connected to the side of the circular block 11. The light rod 12 passes through the first hole 8 and is connected to the first fixed block 3.

[0029] In this embodiment, during actual use of the nail gun 1, when the mechanism is driven, it causes the first fixing block 3 on the first ring 2 to quickly move closer to the second fixing block 5 connected to the second ring 4. At this time, the spring 6 between the first fixing block 3 and the second fixing block 5 is compressed, and simultaneously, the smooth rod 12 connected to the first fixing block 3 slides towards the second hole 9 in the sleeve 7 connected to the second fixing block 5. Due to the force of the spring 6 and the air resistance encountered by the smooth rod 12 when sliding in the sleeve 7, the excessively high firing rate of the nail gun 1 is effectively reduced without affecting the working effect, thereby achieving the effect of reducing noise to silence.

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a third fixing block 13 is fixedly connected to the side of the second ring 4, and a bolt 14 is rotatably connected inside the third fixing block 13. Threaded holes 15 are equidistantly opened on the nail gun 1, and the threaded holes 15 are threadedly connected to the bolt 14.

[0031] In this embodiment: The operator can adjust the distance between the first ring 2 and the second ring 4 by sliding the second ring 4, according to the required nail thickness of the nail gun 1, without affecting normal use. This adjusts the force of the spring 6 and the air resistance experienced by the guide rod 12 when sliding within the sleeve 7. Subsequently, a bolt 14 is used to pass through the third fixing block 13 and screwed into the threaded hole 15 via a threaded connection, thus completing the fixing.

[0032] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, the nail gun 1 has a mounting hole 16 fixedly connected to its side.

[0033] In this embodiment, a metal nail is placed in the mounting hole 16 and then driven into the base material such as concrete using a nail gun 1.

[0034] Working Principle: During the actual operation of the nail gun 1, when the machine body is driven, the first fixing block 3 on the first ring 2 will quickly move closer to the second fixing block 5 connected to the second ring 4. At this time, the spring 6 located between the first fixing block 3 and the second fixing block 5 will be compressed. Simultaneously, the smooth rod 12 connected to the first fixing block 3 will slide closer to the second hole 9 in the sleeve 7 connected to the second fixing block 5. Thanks to the force of the spring 6 and the air resistance encountered by the smooth rod 12 when sliding in the sleeve 7, the excessively high firing speed generated by the piston driven by the gunpowder gas impacting the nail gun 1 is effectively reduced while ensuring the working effect, thereby achieving the effect of reducing noise to silence.

[0035] Secondly, based on the required nail thickness of the nail gun 1, the operator can adjust the distance between the first ring 2 and the second ring 4 by sliding the second ring 4, without affecting normal use. This adjusts the force of the spring 6 and the air resistance encountered by the smooth rod 12 when sliding within the sleeve 7. Subsequently, a bolt 14 is used to pass through the third fixing block 13 and screwed into the threaded hole 15 via a threaded connection, thereby completing the fixation.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
