Description

Technical Field

[0001] This invention relates to a nail gun, and more particularly to a force adjustment device for a nail gun applicable to a variety of nails, and the nail gun thereof. Background Technology

[0002] A nail-driving machine (disclosed in Taiwan Utility Model Patent Publication No. 545350) includes a housing, a holding body, a spring, a firing pin, a spring plate, a nail slot, and a nail guard. When the holding body is pressed, it pulls the firing pin upward, causing the firing pin to pull the spring plate upward. A pivot in the housing causes the front end of the spring plate to bend, accumulating elastic force. When the holding body pivots downward until it abuts against a support shaft and slides backward, a hook plate at the front end disengages from the firing pin. At this point, the firing pin, under the restoring force of the spring plate, momentarily slides downward, striking a nail out of the nail slot, thus achieving the purpose of nail driving.

[0003] Although the aforementioned nailing machine can achieve the intended nailing purpose, the elasticity of the spring and the striking force of the striking pin cannot be adjusted. Therefore, this type of nailing machine is not suitable for work requirements with different nail bodies and different striking depths. Summary of the Invention

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Before the invention is described in detail, it should be noted that similar components are represented by the same numbers in the following description.

[0028] See Figures 1 to 2The first embodiment of the nail gun with a force adjustment device of the present invention includes a housing unit 10, a nail-driving blade 20, a power storage unit 30, a pressure handle unit 40, an elastic unit 50, a force adjustment device 60, and a nail storage unit 70.

[0029] The housing unit 10 includes two housing seats 12 that define a receiving space 11. Each housing seat 12 has a top 121, a bottom 122 extending in a vertical direction Z opposite to the top 121, a groove 123 communicating with the receiving space 11 to the outside, a nail outlet 124 disposed on the bottom 122 and communicating with the receiving space 11 to the outside, a pivot 125 adjacent to the groove 123 and extending in a horizontal direction X perpendicular to the vertical direction Z, and an inclined guide groove 126. The groove 123 is disposed on the top 121. The guide groove 126 extends obliquely from below the groove 123 toward above the nail outlet 124.

[0030] The nail-driving tab 20 is positioned corresponding to the nail outlet 124 and is movable along the vertical direction Z within the receiving space 11. The nail-driving tab 20 has a slot 21 and a connecting slot 22 located below the slot 21.

[0031] The power storage unit 30 is disposed in the accommodating space 11 and provides elastic force for the nail plate 20 to move in the vertical direction Z. In this embodiment, the power storage unit 30 employs a torsion spring and has a ring portion 31 pivotally connected to the pivot 125, a force-receiving arm 32 connected to one end of the ring portion 31, and a driving arm 33 connected to the other end of the ring portion 31. The force-receiving arm 32 has an inverted L-shaped main rod section 321 and a crossbar section 322 intersecting and connected to the main rod section 321. The driving arm 33 is inserted into the connecting groove 22.

[0032] The pressure handle unit 40 includes a handle 41 rotatably pivotally mounted to the housing unit 10, a suspension 42 disposed inside the handle 41 and rotatably pivotally mounted to the housing unit 10, a latching member 43 pivotally connected to the suspension 42 and the housing unit 10, and a spring 44 connecting the suspension 42 and the latching member 43. The suspension 42 has a pressing part 421 located at the bottom, which abuts against the main rod section 321. The latching member 43 has a locking end 431, which is removably engaged in the locking groove 21.

[0033] The elastic unit 50 is disposed in the accommodating space 11 and provides the elastic force for the recovery of the power storage unit 30 and the pressure handle unit 40. The elastic unit 50 includes an elastic element 51 employing a compression spring and a support seat 52 supported by the elastic element 51. The crossbar segment 322 of the force-bearing arm 32 abuts against the support seat 52.

[0034] See also Figure 2 , Figure 3 The force adjustment device 60 includes a guide member 61 and an adjustment unit 62. The guide member 61 is disposed in the receiving space 11. In this embodiment, the guide member 61 is directly integrally formed on one of the housings 12 and protrudes into the receiving space 11 in a protrusion shape. The guide member 61 has a low end 611 adjacent to the nail plate 20, a high end 612 opposite to the low end 611 along a front-back direction Y perpendicular to the vertical direction Z, and an abutment surface 613 extending from the high end 612 to the low end 611. The high end 612 is higher than the low end 611 corresponding to the vertical direction Z. The abutment surface 613 has two stepped abutment portions 614, which are at different heights corresponding to the vertical direction Z. The adjustment unit 62 includes an adjustment member 621 disposed in the accommodating space 11 and movably disposed on the abutment surface 613, a connecting rod 622 pivotally connected to the adjustment member 621 and slidably mounted in the guide groove 126, and an operating member 623 that can actuate the adjustment member 621. The adjustment member 621 provides a limiting abutment when the drive arm 33 of the power storage unit 30 releases its elastic force. The operating member 623 extends from the outside of the housing unit 10 into the accommodating space 11 and is movably disposed in the slide groove 123. The operating member 623 is opposite to the adjustment member 621 and connected to the connecting rod 622. Operating the operating member 623 can move the adjustment member 621 to the abutment portion 614 at different positions on the abutment surface 613, and can adjust the stroke of the power storage unit 30 when releasing its elastic force.

[0035] The nail storage unit 70 is detachably mounted to the housing unit 10 and can store several nails 80. The nail storage unit 70 is compatible with different types of nails 80 (see...). Figure 2 ).

[0036] To further understand the effects of the combination of the components of this invention, the technical means employed, and the expected benefits, the following explanation will be provided, which will hopefully lead to a deeper and more specific understanding of this invention.

[0037] like Figure 1 and Figure 4 , Figure 5As shown, when the entire assembly is complete, the nail storage unit 70 is filled with a predetermined pattern of nails 80, and the pressure handle unit 40 has not yet been pressed, the handle 41 of the pressure handle unit 40 is in a starting position, the clamping part 421 is in an original position, the force-receiving arm 32 of the power storage unit 30 springs against the clamping part 421, and the driving arm 33 drives the nail-driving piece 20 to a non-driving position, with the bottom end of the nail-driving piece 20 slightly higher than the position of the nail 80. The snap-fit ​​end 431 of the latch 43 is engaged in the slot 21 of the nail-driving piece 20, and the elastic unit 50 also springs against the force-receiving arm 32.

[0038] like Figure 6 As shown, when the operator operates and presses down the handle 41 of the pressure unit 40, the handle 41 causes the suspension 42 to rotate relative to the housing unit 10. The braking part 421 of the suspension 42 presses against the force arm 32 of the power storage unit 30, causing the force arm 32 to move towards the bottom 122 of the housing 12 and press against the elastic member 51. This compresses the elastic member 51 and accumulates the potential energy to push the power storage unit 30 towards the top 121 of the housing 12. Furthermore, the handle 41, through the suspension 42, drives the latch 43 to gradually move towards the top 121 and backward, and connects with the nailing plate 20. The nailing plate 20 drives the driving arm 33 of the power storage unit 30 to gradually move towards the top 121, causing the power storage unit 30 to accumulate the potential energy to drive the nailing plate 20 towards the nail outlet 124.

[0039] For example Figure 4 and Figure 5 As shown, when the handle 41 is rotated to a nailing position, the locking end 431 of the latch 43 disengages from the slot 21 of the nailing piece 20. The power storage unit 30 releases potential energy, causing the driving arm 33 of the power storage unit 30 to move the nailing piece 20 toward the nail outlet 124, causing the nail 80 originally located at the nail outlet 124 to perform a nailing action. At this time, the driving arm 33 of the power storage unit 30 moves toward the bottom 122 until it contacts the adjusting member 621 and is blocked, unable to continue moving toward the bottom 122.

[0040] like Figures 6 to 4 As shown, during the period when the handle 41 returns from the nailing position to the starting position, the elastic element 51 releases potential energy and pushes the abutment 52 and the power storage unit 30 to move towards the top 121, thereby causing the suspension 42, the latch 43 and the handle 41 to rotate, and driving the drive arm 33 of the power storage unit 30 to move the nailing piece 20 towards the top 121, until the slot 21 of the nailing piece 20 is inserted by the latching end 431 of the latch 43, so that the nailing piece 20 maintains elastic potential energy.

[0041] For example Figure 7 and Figure 8 As shown, when the nail storage unit 70 is replaced with different types of nails 80, and different nailing depths and nailing intensities are required depending on the type of nail 80, the operator can operate the operating member 623 of the force adjustment device 60 to slide in the slide groove 123. The operating member 623 is linked to the connecting rod 622, and the connecting rod 622 is linked to the adjusting member 621 to move to another abutment 614 at a different height. This allows the operator to adjust the stroke of the force storage unit 30 to release the spring force. By utilizing the change in the stroke of the force storage unit 30 to release the spring force, the nailing plate 20 can be provided with different nailing depths and nailing intensities.

[0042] Operating the pressure handle unit 40 enables the energy storage unit 30 to store and release elastic force. The main rod section 321 of the force-bearing arm 32 is linked to the pressure handle unit 40 and can store the energy of the driving arm 33 to release elastic force.

[0043] See also Figures 9 to 11 The second embodiment of the nail gun with a force adjustment device of the present invention differs from the first embodiment only in the structure and shape of the housing unit 10' and the force adjustment device 60'. Therefore, the following description and corresponding drawings only describe and show the differences.

[0044] Each of the housing unit 10's housing base 12' also includes a first side 127' extending from the top 121' to the bottom 122' and a second side 128' opposite to the first side, and the slide 123' is connected to the outside of the first side 127' by the receiving space 11'.

[0045] The force adjustment device 60' also includes a guide member 61' and an adjustment unit 62'. The adjustment unit 62' has an adjustment member 621' movably disposed on the guide member 61', and an operating member 623' that can be linked to the adjustment member 621'. The operating member 623' is movably inserted into the slide groove 123'.

[0046] In the second embodiment, the operating member 623' is directly connected to the adjusting member 621'. When the operator operates the operating member 623' to slide along the slide groove 123', and the operating member 623' directly moves the adjusting member 621' relative to the guide member 61', the stroke of the energy storage unit 30 releasing the elastic force can be adjusted. Furthermore, by utilizing the change in the stroke of the energy storage unit 30 releasing the elastic force, different nail-driving depths and nail-driving strengths can be provided for the nail-driving piece 20 (see the description and corresponding drawings of the first embodiment). That is to say, the second embodiment omits the connecting rod 622 of the first embodiment, but still achieves the same purpose and effect as the first embodiment.

[0047] Therefore, the force adjustment device of the present invention can be applied to work requirements with different nail bodies and different firing pin depths, and the adjustment operation is quite easy.

[0048] In summary, the nail gun of the present invention, with its force adjustment device, has simple overall components and is easy to manufacture and assemble, thus effectively achieving the purpose of the present invention.
