Description

TECHNICAL FIELD

[0001] The utility model relates to a nail gun, in particular to a hammering type nail gun. BACKGROUND

[0002] Generally, the hammering type nail gun includes two housings and a nail driving mechanism accommodated in the two housings. The two housings are usually made of metal or non-metal. The housing made of metal is formed by concave folding or punching. The shape of the housing is limited due to the difficulty in processing the metal sheet. The nail driving mechanism must be positioned by additional fixing members. The metal housing is heavy, which causes a burden in use. The housing made of non-metal (e.g. plastic or fiber composite) can be formed by a mold. The shape of the housing is not limited, and the housing is easy to manufacture. However, the position of the center of gravity and the counterweight structure of the hammering type nail gun are changed significantly due to the lighter non-metal housing. If the center of gravity is too far forward or too far backward, the holding is unbalanced, uncomfortable and laborious. The hammering effect and efficiency are not good.

[0003] Therefore, it is necessary to provide a novel and advanced hammering type nail gun to solve the above problems. SUMMARY

[0050] The following merely illustrates possible embodiments of the present application, and is not intended to limit the scope of the present application. The term "one" or "at least one" is not intended to limit the quantity, and "a plurality" can also be used. The quantity is intended to be within the scope of the present application, and is described in advance.

[0051] Please refer to Figures 1 to 5 This shows an embodiment of the present invention. The hammer-type nail gun 1 of the present invention includes a main body 10 and a nail-driving mechanism 20.

[0052] The main body 10 includes a hammer head 11 and a handle 12 located at opposite ends. The hammer head 11 includes a nail ejection port 111. A nail-driving mechanism 20 is housed in the hammer head 11. The nail-driving mechanism 20 includes a nail magazine 21 and a nail-driving element 22. The nail magazine 21 is movable toward the nail ejection port 111 to eject the nails 100 from the magazine. The hammer-driven nail gun 1 includes metal and non-metal parts. The main body 10 is a plastic shell and has a total length L1. The distance between the center of gravity W of the hammer-driven nail gun 1 and the nail ejection port 111 along the length of the main body 10 is defined as a center-of-gravity distance L2. A first ratio of the center-of-gravity distance L2 to the total length L1 is between 0.237 and 0.292. This provides a comfortable, effortless, and balanced grip, and also provides good and efficient hammering action.

[0053] The first ratio is preferably between 0.244 and 0.278. The center-of-gravity distance L2 is between 72.0 mm and 82.0 mm. The handle portion 12 has a maximum length L3 and a minimum length L4. A second ratio of the maximum length L3 to the total length L1 is between 0.418 and 0.461, and a third ratio of the minimum length L4 to the total length L1 is between 0.305 and 0.348. For example, the total length L1 is 295.0 mm, the center-of-gravity distance L2 is 77.0 mm, the maximum length L3 of the handle portion 12 is 130.0 mm, and the minimum length L4 of the handle portion 12 is 97.0 mm. The above dimensions may vary depending on different usage requirements and / or different components.

[0054] In this embodiment, the main body 10 further includes a first housing 13 and a second housing 14. The first housing 13 includes at least one hook 131, and the second housing 14 includes at least one hook groove 141. The at least one hook 131 hooks into the at least one hook groove 141, thus allowing for easy and quick assembly and disassembly. Preferably, the first housing 13 and the second housing 14 can be further secured with at least one fastener 15 (such as a screw) to provide a stable and reliable connection.

[0055] Preferably, the hammer head 11 further includes a plurality of guide ribs 112, and the nail-driving mechanism 20 further includes a swing block 23 pivotally connected to the hammer head 11. The swing block 23 can swing between the plurality of guide ribs 112. When the swing block 23 swings, it connects with the nail-driving element 22, which can guide and maintain the swing of the swing block 23 to provide a stable, smooth and effective nail ejection effect. The hammer head 11 further includes a plurality of forward-extending support plates 113, and the nail-driving mechanism 20 further includes a guide rail 24 and an actuating link 25. The guide rail 24 is supported between the plurality of support plates 113, and the actuating link 25 is movably accommodated in the guide rail 24. The actuating link 25 is used to trigger the release of the nail-driving element 22. The plurality of support plates 113 can stably hold the guide rail 24 so that the triggering of the actuating link 25 is more accurate.

[0056] In detail, the nail-driving mechanism 20 further includes an attachment portion 26, which is integrally formed with the guide rail 24 as a single component. The attachment portion 26 is attached to the hammer head 11 and spans across the nail box 21. The main body 10 further includes at least one counterweight slot 16 for accommodating a counterweight component. The hammer head 11 further includes at least one removable metal cover 114, which covers the at least one counterweight slot 16. In this embodiment, the at least one metal cover 114 includes a first metal cover 115 and a second metal cover 116 that are partially overlapped. The first metal cover 115 covers the front and left and right sides of the hammer head 11, and the second metal cover 116 covers the upper and left and right sides of the hammer head 11, which facilitates installation and allows for adjustment of different counterweights as needed.

[0057] The metal portion, excluding the pins 100, has a fourth weight ratio of 2.850 to 3.150 to the weight of the non-metallic portion. A fifth weight ratio of the total weight of the metal portion and the pins 100 to the weight of the non-metallic portion is 3.030 to 3.138. The metal portion includes, for example, the nail cartridge 21, the nail-driving member 22, the at least one fastening member 15, the oscillating block 23, the guide rail 24, the attachment portion 26, the at least one metal cover 114, a pivot, and an elastic element. The pins 100 can be, for example, a row of 168 pins weighing 8.21 grams, a row of 168 pins weighing 10.045 grams, a row of 168 pins weighing 11.515 grams, or a row of 168 pins weighing 13.36 grams. The nail cartridge 21 can hold one or more rows of pins.
