Description

Technical Field

[0002] Generally, nail guns on the market include a spring piece, a pressure rod, a hook and a strike plate installed on a main body. The strike plate is respectively assembled with the spring piece and the hook. When the pressure rod is pressed, the pressure rod will cause the spring piece to deform, and the hook will still limit the strike plate to prevent the strike plate from moving and striking toward the nail outlet of the main body, so as to store elastic energy. When the pressure rod is pressed to a firing position, the pressure rod will drive the hook to separate from the strike plate, and the strike plate will be driven by the spring piece to strike toward the nail outlet to drive out the nail. For example, the nail gun disclosed in Taiwan Patent Case I546166 belongs to this category.

[0025] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of the present invention. The "one" or "at least one" preceding the nouns mentioned in the text does not limit the quantity, and the number can also be "plural" according to needs. This change in quantity is also within the scope of protection, which is described first.

[0026] Please refer to Figures 1 to 9 , which shows an embodiment of the present invention. The nail gun of the present invention includes: a main body 1, a firing mechanism 2 and a buffer block 3.

[0027] The main body 1 includes a nail outlet 11, and the opening direction of the nail outlet 11 is defined as a nail outlet direction 4. The firing mechanism 2 is movably connected to the main body 1, and includes a driving unit and a striking member 23 that are connected to each other. The driving unit is used to drive the striking member 23 to move along the nail outlet direction 4 toward the nail outlet 11.

[0028] The buffer block 3 is positioned on the main body 1, and the buffer block 3 is between the driving unit and the nail outlet 11 in the nail outlet direction 4. The buffer block 3 is used to support the driving unit swinging toward the nail outlet 11, and the buffer block 3 includes at least one buffer hole 31, and the at least one buffer hole 31 extends in a direction transverse to the nail outlet 11; wherein, the at least one buffer hole 31 provides the buffer block 3 with the margin space required for deformation, so that the buffer block 3 can be partially deformed after being subjected to force, and can have better buffering, shock absorption, and sound absorption effects, so that the impact force generated by the driving unit swinging on the buffer block 3 will not be transmitted to the main body 1, thereby achieving the purpose of protecting the structural integrity of the main body 1, extending the service life of the nail gun, reducing the sound during firing, and so on.

[0029] Further, the driving unit further includes an operating member 21, a hooking member 22, a pressure member 24 and an elastic member 25. The operating member 21 is movable between a first position and a second position and is disposed on the main body 1. The hooking member 22 is movably disposed on the main body 1 to hook the impact member 23. The impact member 23 is movably disposed on the main body 1 along the nail-out direction 4 relative to the nail-out opening 11. One end of the pressure member 24 is pivotally connected to the main body 1, and the other end is connected to the operating member 21. The pressure member 24 includes a bearing portion 241 and a pressing portion 242. A first side portion 251 of the elastic member 25 is limited to the bearing portion 241, and a second side portion 252 of the elastic member 25 is limited to the bearing portion 241. The impact member 23 is penetrated and connected. When the operating member 21 is located at the first position, the hooking member 22 hooks the impact member 23, and the impact member 23 remains in position and cannot move. When the operating member 21 is driven by an external force and moves from the first position toward the second position, the operating member 21 links the pressure member 24 to make the pressing portion 242 press against the elastic member 25 to deform it. When the operating member 21 reaches the second position, the operating member 21 actuates the hooking member 22 to release the impact member 23, and the second side portion 252 of the elastic member 25 swings to drive the impact member 23 to move toward the nail outlet 11, and then the second side portion 252 of the elastic member 25 swings to hit the buffer block 3.

[0030] The buffer block 3 includes a top 32 and a bottom 33 opposite to each other, the top 32 faces the driving unit, and the bottom 33 faces away from the driving unit; wherein the at least one buffer hole 31 does not penetrate at least one of the top 32 and the bottom 33 to ensure the integrity of the contact surface between the top 32 and the elastic member 25 of the driving unit, and the integrity of the contact area between the bottom 33 and the main body 1.

[0031] Specifically, the top 32 includes a first surface 321 and a second surface 322 which are connected obliquely, and the first surface 321 is closer to the impact member 23 than the second surface 322; wherein, when the elastic member 25 of the driving unit swings against the buffer block 3, the first surface 321 is used to abut against the elastic member 25 of the driving unit, and the inclined first surface 321 allows the buffer block 3 to be arranged on the main body 1 in a direction in which the bottom 33 is parallel to the nail outlet 11, and a gap 34 is maintained between the second surface 322 and the elastic member 25 of the driving unit, and the gap 34 can provide a margin space for the second surface 322 to deform under force.

[0032] Furthermore, the area of ​​the first surface 321 is larger than the area of ​​the second surface 322 to ensure a larger contact area with the second side portion 252, and the first surface 321 extends continuously from the connection with the second surface 322 toward the impact member 23. Specifically, the first surface 321 is oblique to the nail-out direction 4, and the second surface 322 is perpendicular to the nail-out direction 4, and the first surface 321 and the second surface 322 are between 160 degrees and 175 degrees.

[0033] In this embodiment, the number of the at least one buffer hole 31 is plural, and the plurality of buffer holes 31 are arranged in at least one row 35. The plurality of buffer holes 31 in any row 35 are arranged at intervals in a direction parallel to the first surface 321, so that the buffer block 3 can be locally deformed at different positions; wherein the hole shape of each buffer hole 31 is circular. Moreover, the aperture of the buffer hole 31 closer to the top 32 is smaller than the aperture of the buffer hole 31 closer to the bottom 33, so as to ensure that the structure of the buffer block 3 near the top 32 has better structural strength to withstand swinging.

[0034] Preferably, the buffer block 3 further includes a weakening groove 36, which is concavely disposed in the bottom 33 to make the structural strength of the bottom 33 slightly weaker and easier to deform. In this way, when the top 32 is hit by the elastic member 25, the bottom 33 can react and deform more quickly. In this embodiment, the weakening groove 36 extends in a straight line and is located in the center of the bottom 33, so that the buffer block 3 is more likely to be deformed and concave in the center after being subjected to force, so that the force can be evenly dispersed outward from the center.

[0035] The main body 1 further includes a supporting portion 12 and two limiting portions 13, the two limiting portions 13 are protruded from the supporting portion 12 at intervals to jointly define a receiving chamber 14, the buffer block 3 further includes two slots 37, the two slots 37 are used to be plugged with the two limiting portions 13, the portion of the buffer block 3 located in the receiving chamber 14 is defined as a first portion 38, the portion of the buffer block 3 protruding from the receiving chamber 14 is defined as a second portion 39, the second portion 39 is used to support the elastic member 25 of the driving unit swinging toward the nail outlet 11; wherein, the second portion 39 includes a plurality of superimposed blocks 391, and the size of the plurality of blocks 391 is reduced in the direction away from the first portion 38, so that the side surface of the second portion 39 is stepped, when the second side portion 252 swings the block 391 located at the top, the force will be transmitted in the direction toward the first portion 38 and diffuse outward layer by layer, so as to achieve the purpose of dispersing stress.

[0036] In this embodiment, the outer contour of each block 391 is rectangular, and the plurality of blocks 391 are concentrically arranged, and any side of the second portion 39 is stepped. In addition, each slot 37 extends in parallel with the direction of the buffer hole 31, and the size of the slot 37 close to the impact member 23 in the nail-out direction 4 is larger than the size of the inserted limiter 13 in the nail-out direction 4, so that the second portion 39 can shake relative to the two limiters 13 after being hit by the second side portion 252, thereby consuming the impact force. In addition, the second portion 39 is spaced apart from the main body 1 on the two opposite sides perpendicular to the nail-out direction 4, so as to ensure that the second portion 39 will not touch the main body 1 when it is compressed and extended and deformed perpendicular to the nail-out direction 4, thereby ensuring the structural integrity of the main body 1.

[0037] The above are preferred embodiments of the present invention and the technical principles used therein. For those skilled in the art, any obvious changes such as equivalent transformations, simple replacements, etc. based on the technical solution of the present invention, without departing from the spirit and scope of the present invention, are within the scope of protection of the present invention.
