Abstract
Description
Technical Field
[0001] This disclosure relates to the field of power tool technology, and in particular to a nail gun. Background Technology
[0002] Nail guns are mainly used in industries such as construction and interior decoration. Their working principle is as follows: when the nozzle is pressed down and the switch is pressed, the motor is started. The firing pin drive mechanism drives the firing pin from the initial locked ready position to drive the piston to compress air backward. After the firing pin disengages from the firing pin drive mechanism, it is suddenly released to strike the row of nails in the nail magazine that have been pushed into the nail holder by the nail pusher, causing them to be ejected from the nozzle.
[0003] Because traditional nail guns have a fixed magazine width, they cannot accommodate nails of different lengths. Especially when firing upwards, hard objects or debris such as dust, sand, or nail fragments can easily enter the magazine and come into contact with the nails, causing them to be misaligned and prone to jamming. Furthermore, given the limited magazine size, some users still load nails of different sizes. In this case, because the nail sizes are incompatible with the limiting components or guide grooves, the nails may become stuck in the nailing channel during the nailing process.

[0027] As can be seen from the background technology, nail guns in related technologies are prone to nail jamming.
[0028] refer to Figure 1 , Figure 1 This is a partial structural diagram of a traditional nail gun magazine. The width of the magazine 40 in a traditional nail gun is fixed. When a short strip of nails 41 is loaded into the magazine, there is a large gap between the end of the strip of nails and the magazine wall located on the side of the muzzle 42 (as shown in the elliptical area in the figure). When the muzzle is fired upwards, hard objects or debris such as dust, mud, or nail fragments can easily enter the magazine assembly along with the firing pin. Finally, they will follow the nail pusher and its strip of nails into the firing mechanism, causing the strip of nails to be misaligned. After the strip of nails is misaligned, it is easy for it to hit the front trajectory, which can easily lead to dangerous operations such as nail jamming.
[0029] This disclosure provides a nail gun that, through a combination of a limiting component and a guide groove in the magazine assembly, limits and guides the first and second rows of nails, respectively. This allows the magazine to accommodate rows of nails of different lengths, improving its versatility and practicality. Simultaneously, this structure helps prevent nail misalignment or jamming during transport, thereby enhancing the safety and reliability of the nail gun.

[0032] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the embodiments of this disclosure to facilitate a better understanding of the disclosure. However, the technical solutions claimed in this disclosure can be implemented even without these technical details and various variations and modifications based on the following embodiments.
[0033] refer to Figures 2 to 6 Nail guns include:
[0034] A striking assembly, comprising a striking pin 1, which is positioned along a first direction X and configured to strike a row of pins 2;
[0035] Housing 3 is configured to contain impact components;
[0036] The magazine assembly 10 is configured to accommodate the pins 2. The magazine assembly 10 includes a receiving cavity 11 and a pin feeding assembly 20. The receiving cavity 11 includes a first limiting component 101 and a second limiting component 102. The first limiting component 101 is configured to limit the first pins 21 and includes a first guide groove 111. The second limiting component 102 is configured to limit the second pins 22 and includes a second guide groove 112. The pin feeding assembly 20 includes a first pin feeding push plate 201 and a second pin feeding push plate 202. The first pin feeding push plate 201 slides along the first guide groove 111 and is configured to push the first pins 21. The second pin feeding push plate 202 slides along the second guide groove 112 and is configured to push the second pins 22.
[0037] The first guide groove 111 and the second guide groove 112 (hereinafter collectively referred to as guide grooves) are used to limit the sliding path of the first nail feeding pusher 201 and the second nail feeding pusher 202 (hereinafter collectively referred to as nail feeding pusher), respectively, and at the same time assist the nail pack 2 in maintaining the correct posture during the pushing process, ensuring that it moves smoothly in the specified direction and preventing deviation or tilting.
[0038] Guided by the guide groove, the nail feeding pusher moves to push the nails to the striking position in an orderly manner, thereby ensuring the stability and reliability of the nail feeding process and effectively avoiding problems such as nail jamming or striking failure caused by incorrect nail position.
[0039] The nail gun provided in this embodiment achieves effective limiting and precise pushing of nails of different lengths by incorporating a receiving cavity including a first limiting component and a second limiting component in the magazine assembly, and cooperating with a first nail-feeding push plate and a second nail-feeding push plate having guide grooves. This structure not only improves the magazine's adaptability to various specifications of nails, but also significantly reduces the risk of nails becoming misaligned or stuck during transport, thereby enhancing the safety and reliability of the nail gun.
[0040] The embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.
[0041] In some embodiments, the first limiting component 101 further includes a first positioning member 121, which includes a plurality of protrusions 1211 disposed on the inner wall of the receiving cavity 11. The protrusions extend along the second direction Y, and the first positioning member 121 restricts the first row of nails 21 from moving along the first direction X.
[0042] In some embodiments, the second limiting component 102 further includes a second positioning member 122, which includes a plurality of protrusions 1221 disposed on the inner wall of the receiving cavity 11. The protrusions 1221 extend along a second direction, and the second positioning member 122 restricts the movement of the second row of nails 22 along a first direction.
[0043] Wherein, the second direction Y is the pushing direction of the first row of nails 21 and the second row of nails 22, that is, the direction in which the first row of nails 21 and the second row of nails 22 move in the magazine assembly 10; the first direction X is the extending direction of the first row of nails 21 and the second row of nails 22.
[0044] The protrusion 1211 is arranged in contact with or adjacent to the side of the first row of nails 21 to restrict the movement of the first row of nails 21 in the first direction X, and to prevent abnormal situations such as nail jamming or misalignment caused by the first row of nails 21 shifting or tilting during the pushing process, thereby improving the safety and reliability of the nail gun during use.
[0045] The protrusion 1221 is arranged in contact with or adjacent to the side of the second row of nails 22 to restrict the movement of the second row of nails 22 in the first direction X, and to prevent the second row of nails 22 from deviating or tilting during the pushing process, thereby improving the safety and reliability of the nail gun during use.
[0046] refer to Figure 2 In some embodiments, the first direction X and the second direction Y are perpendicular to each other.
[0047] In some embodiments, when the magazine assembly 10 simultaneously accommodates the first row of nails 21 and the second row of nails 22, the ends of the first row of nails 21 and the ends of the second row of nails 22 are aligned in a second direction.
[0048] In some embodiments, the first row of pins 21 includes a first locking block 211 slidably connected to the first guide groove 111, the shape and size of the first locking block 211 matching the first guide groove 111.
[0049] In some embodiments, the second row of nails 22 includes a second locking block 221 slidably connected to the second guide groove 112, the shape and size of the second locking block 221 matching the second guide groove 112.
[0050] The first row of nails 21 and the first guide groove 111 are guided and engaged by the first locking block 211, and the second row of nails 22 and the second guide groove 112 are guided and engaged by the second locking block 221. The two sets of structures are independent of each other and do not interfere with each other.
[0051] By setting a first locking block 211 and a second locking block 221 on the first row of nails 21 and the second row of nails 22 respectively to match the first guide groove 111 and the second guide groove 112, the nails are accurately guided and stably slid during the nail feeding process. This not only enhances the positioning ability of the nails in the receiving cavity, but also effectively prevents abnormal situations such as nail jamming or misaligned nails caused by nail offset, tilting or shaking.
[0052] In some embodiments, the length of the first row of nails 21 is 15mm to 27mm, for example, it can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm or 27mm; the length of the second row of nails 22 is 28mm to 40mm, for example, it can be 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm or 40mm.
[0053] In some embodiments, the magazine assembly 10 further includes an elastic element connected to the nail feeding assembly 20, which pushes the nail feeding assembly 20 to move in a second direction to push the row of nails 2.
[0054] The elastic element has one end fixed to the housing of the magazine assembly 10 and the other end connected to the nail feeding assembly 20. The elastic element is configured to apply force in the second direction to push the nail feeding assembly 20 to move in the second direction, so that the nail feeding assembly 20 can fit against the row of nails 2 and continue to push forward. The initial state of the elastic element is a compressed or pre-tightened state to ensure that the nail feeding assembly 20 always has a tendency to move forward.
[0055] In some embodiments, the elastic element is a compression spring or a torsion spring, etc.
[0056] In some embodiments, the first row of nails 21 includes a first receiving portion 212, and the working surface of the first nail feeding pusher 201 abuts against the first receiving portion 212.
[0057] In some embodiments, the second row of nails 22 includes a second receiving portion 222, and the working surface of the second nail feeding pusher 202 abuts against the second receiving portion 222.
[0058] In some embodiments, the first receiving portion 212 and the second receiving portion 222 (hereinafter collectively referred to as receiving portions) may be local protrusions, grooves, steps or other structures on the pin pack that can be used to bear force, for forming an effective force transmission connection with the pin feeding pusher.
[0059] In some embodiments, the working surface of the nail feeding pusher can be designed as a flat or slightly curved surface to increase the contact area between the working surface and the receiving part and improve the friction, thereby ensuring a stable and reliable pushing process.
[0060] The first receiving part 212 and the first nail feeding pusher 201, and the second receiving part 222 and the second nail feeding pusher 202, form a one-to-one working relationship. The two sets of structures are independent of each other and do not interfere with each other during operation.
[0061] Through this contact and engagement method, the nail feeding pusher can effectively transmit the power provided by the elastic element or drive mechanism to the corresponding nail row, avoiding abnormal phenomena such as slippage, empty push or deviation, thereby ensuring the continuity and stability of the nail feeding action.
[0062] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of this disclosure. Any person skilled in the art can make various alterations and modifications without departing from the spirit and scope of this disclosure; therefore, the scope of protection of this disclosure should be determined by the scope defined in the claims.
