Description

Technical Field

[0001] This application relates to the field of hardware tools technology, and in particular to a nail gun. Background Technology

[0002] In practical production and daily life, it is sometimes necessary to use fasteners such as nails to connect or fix objects. Manual hammering would be labor-intensive and inefficient. Therefore, nail guns are commonly used in related technologies to drive nails into the work surface. A nail gun, as a fastener actuator, is used to quickly drive nails into the work surface. Common nail guns include compressed air-driven nail guns and mechanical spring-driven nail guns. Compressed air-driven nail guns have a compressed air cylinder; the thrust generated by the extended piston rod acts as the driving force on the impact component, driving the nail into the work surface. Mechanical spring-driven nail guns have an impact spring (compression spring); after the impact spring is compressed, the spring's restoring force acts as the driving force on the impact component, driving the nail into the work surface.

[0003] The bottom of the nail gun has a nail storage cavity, which is typically formed by two guide rails: an inner guide rail and an outer guide rail. The outer guide rail usually includes a first outer rail and a second outer rail, both of which are inverted U-shaped. The second outer rail is positioned inside the first outer rail, with the end of the first outer rail bent inwards to block the end of the second outer rail. A track groove is formed between the bent portion of the first outer rail and the end of the second outer rail, and this groove, in conjunction with the inner guide rail, allows the inner guide rail to be installed inside the outer guide rail. This design requires the separate fabrication of two guide rails, making the process complex. Furthermore, the first and second outer rails are connected and fixed by welding, requiring high precision in the weld quality; otherwise, malfunctions such as nail jamming can easily occur. Utility Model Content

[0004] Therefore, it is necessary to provide a nail gun that can simplify the process and is less prone to nail jamming.

[0005] A nail gun includes a nail-holding assembly for receiving nails. The nail-holding assembly includes a first guide rail and a second guide rail, the second guide rail being disposed inside the first guide rail. The front end of the nail-holding assembly has a nail outlet. The side wall of the first guide rail is integrally formed with a guide rail groove. The second guide rail has a guide rib extending toward the guide rail groove. The guide rib extends into the guide rail groove to define the relative position of the first guide rail and the second guide rail. A nail-holding gap is formed between the first guide rail and the second guide rail. The nail-holding gap is used to receive nails. A nail-pushing mechanism for pushing nails to the nail outlet is also provided in the nail-holding gap.

[0006] In one embodiment, the guide rail groove is formed by stamping the first guide rail, and the guide rail groove protrudes from the two side walls of the first guide rail.

[0007] In one embodiment, the nail gun further includes a nail-driving blade, an operating handle, and a leaf spring. The nail-driving blade is movably disposed above the nail outlet. The front end of the operating handle is detachably connected to the nail-driving blade to control the nail-driving blade to move upward. The front end of the leaf spring is connected to the nail-driving blade, and when the front end of the operating handle is separated from the nail-driving blade, the leaf spring can control the nail-driving blade to move downward to strike the nail located at the nail outlet.

[0008] In one embodiment, the leaf spring is a one-piece structure, and the thickness of the leaf spring is 1.3mm to 1.8mm.

[0009] In one embodiment, the leaf spring is provided with reinforcing ribs that extend along the length of the leaf spring.

[0010] In one embodiment, the reinforcing rib is located in the central region of the leaf spring.

[0011] In one embodiment, the nail gun further includes a housing, the nail placement assembly is disposed at the bottom of the housing, the leaf spring is disposed inside the housing, and the operating handle includes a handle body, a connector, and an elastic element. The handle body is rotatably mounted on the housing via a pivot, the front end of the handle body extends into the housing, the rear end of the handle body extends out of the housing, and the connector is movable back and forth to the front end of the handle body via the elastic element.

[0012] In one embodiment, the nailing piece is provided with a mating hole, and the front end of the connector is provided with a connecting part, which can extend into or move out of the mating hole.

[0013] In one embodiment, a torsion spring is sleeved on the outside of the pivot, with both ends of the torsion spring located on the side of the pivot away from the nailing plate. One end of the torsion spring abuts against the lower side of the handle body, and the other end is connected to the outer shell.

[0014] In one embodiment, the front end of the first guide rail is provided with a first positioning piece and a second positioning piece, which are spaced apart to define the nail outlet.

[0015] Compared with the prior art, the nail gun provided in this application has a guide rail groove integrally formed on the side wall of the first guide rail. Only one guide rail needs to be processed during processing, which omits the welding step, thereby simplifying the process and avoiding the problem of nail jamming caused by low welding quality.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0033] Please see Figures 1 to 10 This application provides a nail gun, including a nail placement assembly 10 for accommodating nails 70. The nail placement assembly 10 includes a first guide rail 11 and a second guide rail 12, with the second guide rail 12 disposed inside the first guide rail 11. The front end of the nail placement assembly 10 is provided with a nail outlet 13. The side wall of the first guide rail 11 is integrally formed with a guide rail groove 111. The second guide rail 12 is provided with a guide rib 121 extending toward the guide rail groove 111. The guide rib 121 extends into the guide rail groove 111 to define the relative position of the first guide rail 11 and the second guide rail 12. A nail-accommodating gap 14 is formed between the first guide rail 11 and the second guide rail 12. The nail-accommodating gap 14 is used to accommodate the nails 70. A nail-pushing mechanism 60 for pushing the nails 70 to the nail outlet 13 is also provided in the nail-accommodating gap 14. In this way, the guide rail groove 111 is integrally formed by the first guide rail 11. Only one guide rail needs to be processed during processing, which omits the welding step, thereby simplifying the process and avoiding the problem of easy jamming caused by low welding quality.

[0034] Please see Figures 3 to 5 Furthermore, the guide groove 111 is formed by stamping the first guide rail 11, and the guide groove 111 protrudes from the two side walls of the first guide rail 11. Thus, the guide groove 111 is formed by stamping, and the stamping process is mature and easy to implement.

[0035] Please see Figure 2 , Figure 6 and Figure 7The nail gun also includes a nailing blade 20, an operating handle 30, and a leaf spring 40. The nailing blade 20 is vertically movable above the nail outlet 13. The front end of the operating handle 30 is detachably connected to the nailing blade 20 to control its upward movement. The front end of the leaf spring 40 is connected to the nailing blade 20, and when the front end of the operating handle 30 is separated from the nailing blade 20, the leaf spring 40 controls the nailing blade 20 to move downward to strike the nail 70 located in the nail outlet 13. During the nailing action, the user lifts the nailing blade 20 upward by operating the handle 30. At this time, the front end of the leaf spring 40 deforms due to the upward tension of the nailing blade 20, thereby accumulating elastic force. When the front end of the operating handle 30 is disengaged from the nailing blade 20, the nailing blade 20 moves downward under the elastic force of the leaf spring 40, thereby striking the nail 70.

[0036] In the prior art, leaf spring 40 is typically formed by welding two springs together. In this embodiment, leaf spring 40 is a one-piece structure, and the thickness of leaf spring 40 is 1.3mm~1.8mm. Thus, leaf spring 40 has sufficient elastic force. Furthermore, the one-piece structure of leaf spring 40 eliminates the need for welding, thereby reducing costs and avoiding any impact of welding on the elastic force of leaf spring 40.

[0037] Furthermore, the leaf spring 40 is provided with reinforcing ribs 41, which extend along the length of the leaf spring 40. Thus, by providing reinforcing ribs 41, the structural strength of the leaf spring 40 can be improved, thereby saving material costs and extending its service life while ensuring the performance of the leaf spring 40 itself.

[0038] Furthermore, the reinforcing rib 41 is located in the central region of the leaf spring 40. When the leaf spring 40 deforms, the central region of the leaf spring 40 experiences greater stress. In this embodiment, by placing the reinforcing rib 41 in the central region of the leaf spring 40, the structural strength of the central region of the leaf spring 40 can be enhanced, thus making the leaf spring 40 less prone to damage.

[0039] Please see Figure 1 and Figure 2 The nail gun also includes a housing 50, a nail-holding assembly 10 disposed at the bottom of the housing 50, and a leaf spring 40 disposed inside the housing 50. See also... Figure 6 and Figure 7The operating handle 30 includes a handle body 31, a connector 32, and an elastic element 33. The handle body 31 is rotatably mounted on the housing 50 via a pivot 36. The front end of the handle body 31 extends into the housing 50, and the rear end extends out of the housing 50. The connector 32 is movably connected to the front end of the handle body 31 via the elastic element 33. Thus, the operating handle 30 forms a lever structure. When the user presses down on the rear end of the handle body 31, the handle body 31 rotates around the pivot 36, causing the front end of the handle body 31 to move upward. This lever structure enables effortless operation. In this embodiment, the connector 32 is connected to the front end of the handle body 31 via the elastic element 33, allowing the connector 32 to move back and forth, thus facilitating the connection or separation of the operating handle 30 and the nailing clip 20.

[0040] Furthermore, the nail-driving piece 20 is provided with a mating hole 21, and the front end of the connector 32 is provided with a connecting part 321, which can extend into or move out of the mating hole 21. Thus, by extending the connecting part 321 into the mating hole 21, the operating handle 30 and the nail-driving piece 20 can be connected. When the user presses down on the handle body 31, the front end of the handle body 31 and the connector 32 move upward together, allowing the connector 32 to lift the nail-driving piece 20 upward by abutting against the top wall of the mating hole 21. When the connecting part 321 moves out of the mating hole 21, the operating handle 30 and the nail-driving piece 20 disengage. At this time, under the elastic force of the leaf spring 40, the nail-driving piece 20 quickly moves downward, thereby striking the nail 70.

[0041] In this embodiment, the elastic element 33 is a compression spring, the handle body 31 is provided with a first connecting post 311, and the rear end of the connector 32 is provided with a second connecting post 322. The two ends of the elastic element 33 are respectively connected to the first connecting post 311 and the second connecting post 322. In this way, the elastic element 33 provides the connector 32 with an elastic force for forward movement.

[0042] In this embodiment, the connecting portion 321 is triangular, and its upper surface is lower than that of the connecting member 32, so that the sidewall of the connecting member 32 forms a stepped surface 323. When the connecting member 32 moves forward under the elastic force of the elastic member 33, the connecting portion 321 extends into the mating hole 21. By setting the stepped surface 323, the forward movement distance of the connecting member 32 can be limited, so that the connecting member 32 moves at most until the stepped surface 323 abuts against the sidewall of the nailing piece 20. Of course, in other embodiments, the forward movement distance of the connecting member 32 can also be limited in other ways, and this application does not limit this.

[0043] Please see Figures 6 to 8A guide structure is provided between the connector 32 and the handle body 31 to guide the connector 32 to move back and forth, improving the stability of the connector 32's back and forth movement. In this embodiment, the connector 32 has a U-shaped cross-section, and the front end of the handle body 31 extends into the connector 32. The guide structure includes a first sliding hole 324, which is provided on the connector 32 and extends along the length direction of the connector 32. The handle body 31 has a first connecting hole 314, and a first fastener 34 passes through the first sliding hole 324 and the first connecting hole 314 to connect the handle body 31 and the connector 32. The first fastener 34 can move back and forth along the first sliding hole 324. The guide structure also includes a second sliding hole 315, which is provided on the handle body 31 and extends along the length direction of the handle body 31. The connector 32 has a second connecting hole 325, and a second fastener 35 passes through the second sliding hole 315 and the second connecting hole 325 to connect the handle body 31 and the connector 32. The second fastener 35 can move back and forth along the second slider. Thus, the cooperation between the first sliding hole 324 and the first fastener 34, and the cooperation between the second sliding hole 315 and the second fastener 35, effectively guides the back-and-forth movement of the connector 32, ensuring the stability of the connecting portion 321 at the front end of the connector 32 as it moves in or out. Of course, in other embodiments, the guide structure may include only one of the first sliding hole 324 and the second sliding hole 315, or the guide structure may be in the form of a slide rail or groove. This application does not limit this, as long as the guide structure can guide the back-and-forth movement of the connector 32.

[0044] Please see Figures 6 to 8 A torsion spring 37 is sleeved on the outer side of the rotating shaft 36. Both ends of the torsion spring 37 are located on the side of the rotating shaft 36 away from the nailing piece 20. One end of the torsion spring 37 abuts against the lower side of the handle body 31, and the other end is connected to the outer shell 50. Thus, when the user presses down on the handle body 31, the torsion spring 37 is compressed and deformed. When the user releases the handle body 31, the handle body 31 automatically returns to its original position under the elastic force of the torsion spring 37, that is, the handle body 31 rotates in the opposite direction around the rotating shaft 36. During this rotation, the rear end of the handle body 31 moves upward and the front end moves downward, thereby causing the connecting part 321 to rotate downward and disengage from the mating hole 21. It can be understood that, in order to facilitate the disengagement of the connecting part 321 from the mating hole 21, the lower end of the connection between the connector 32 and the connecting part 321 is rounded. Thus, when the front end of the handle body 31 moves downward, the connecting part 321 can smoothly disengage from the mating hole 21.

[0045] Please see Figure 3The first guide rail 11 has a first positioning piece 112 and a second positioning piece 113 at its front end. The first positioning piece 112 and the second positioning piece 113 are spaced apart to define the nail outlet 13. This results in a very simple structure, reducing the likelihood of nail jamming. It is understood that the width of the nail outlet 13 is the same as the width of a nail 70, thus ensuring that the nailing board strikes only one nail 70 at a time. In this embodiment, the first positioning piece 112 is integrally formed on the top wall of the first guide rail 11, and the second positioning piece 113 is connected to the end wall of the first guide rail 11. The second positioning piece 113 is approximately U-shaped and can be connected to the first guide rail 11 by snap-fit ​​or welding; this application does not impose any limitations on this.

[0046] like Figure 4 As shown, in this embodiment, the nail-accommodating gap 14 is suitable for accommodating a door-shaped row of nails, that is, as... Figure 10 The nail 70 is shown. To install nail 70, simply hang the door-shaped nail bar on the second guide rail 12. Please refer to... Figure 4 and Figure 7 As shown.

[0047] like Figure 7 and Figure 9 As shown, the pusher mechanism 60 includes a pusher plate 61 and a pusher spring 62. The pusher plate 61 is located at the rear of the door-shaped nail bar. The two ends of the pusher spring 62 are connected to the pusher plate 61 and the first guide rail 11 (or the second guide rail 12), respectively. The pusher spring 62 can apply a force to the pusher plate 61 to move towards the front end of the nail placement assembly 10, so that the first nail 70 at the front end of the door-shaped nail bar is always located at the nail outlet 13. As shown, the first guide rail 11 is provided with a reversing post 63. The pusher spring 62 passes around the reversing post 63 and is connected to the pusher plate 61. Thus, one end of the pusher spring 62 connected to the first guide rail 11 (or the second guide rail 12) can be connected to the rear end of the first guide rail 11 (or the second guide rail 12). Therefore, the pusher spring 62 can be of a longer size, and the elastic force of the pusher spring 62 can enable the pusher plate 61 to better push the door-shaped nail bar forward.

[0048] Please combine Figures 1 to 10The nailing process of the nail gun of this application is as follows: The user presses the rear end of the handle body 31, causing the handle body 31 to rotate around the pivot 36, which moves the front end of the handle body 31 upward, thereby moving the nailing disc 20 upward. At the same time, the nailing disc 20 moves the front end of the leaf spring 40 upward, causing the leaf spring 40 to deform, and the torsion spring 37 to be compressed and deformed. When the nailing disc 20 moves to a certain height, the handle body 31 is released. Under the elastic force of the torsion spring 37, the handle body 31 rotates in the opposite direction to reset, with the rear end of the handle body 31 moving upward and the front end moving downward, thereby moving the connector 32 backward, causing the connecting part 321 to disengage from the mating hole 21. At the same time, the connector 32 compresses the elastic element 33. After the connecting part 321 disengages from the mating hole 21, under the elastic force of the leaf spring 40, the nailing disc 20 quickly moves downward, thereby striking the nail 70 located at the nail outlet 13. Thus, one nailing process is completed. Understandably, after the nailing is completed, the nailing blade 20 returns to its original position. Under the elastic force of the elastic element 33, the connecting part 321 re-enters the mating hole 21. At the same time, the nail pushing mechanism 60 moves the nail 70 in the nail receiving gap 14 forward to the nail outlet 13, in preparation for the next nailing.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
