Description

Nail gun with guide mechanism

The invention relates to a nail gun, and in particular to a nail gun with a nail guiding mechanism.

No. 5,692, 665 discloses a guide pin structure in which a two-lead pin is selectively pivoted to the front of a nail rail by its elastic force, thereby aligning the staple pin, which can be pivotally pivoted and pushed by a shrapnel Let it pivot toward the nail rail. The guiding pin of such a structure will tilt toward the nail opening when the nail is fixed, which causes the end of the nail to be biased toward the nail and is easy to staple.

In addition, in order to enable a nail gun to use a variety of sizes of staples, such as those disclosed in TWM355151, a pressure plate is mainly provided at the front end of the nail, and a control member is provided in the receiving hole of the gun body. Pushing the pressure plate to allow the pressure plate to move relative to each other along the front and rear ends of the gun body, so the user can control the control member to displace the pressure plate, thereby controlling the gap size of the nail gun to avoid hitting during the firing. The board will push the two nails at the same time, which will affect the effect of the firing and cause the staples. However, such a nail gun must adjust the control member with different staples, but it is still possible to forget the adjustment due to human negligence, which causes the simultaneous firing of the two staples.

Therefore, it is necessary to provide a novel and progressive nailing gun with a nail guiding mechanism to solve the above problems.

The main object of the present invention is to provide a nail gun with a nail guiding mechanism, which can avoid the problem of pinning and can be applied to nails of different specifications.

In order to achieve the above object, the present invention provides a nail gun with a nail guiding mechanism, comprising: a body having a nail opening and a nail, one of the nails is connected to the nail opening; a nail guiding mechanism, The invention comprises a guiding plate for the outlet and a biasing mechanism disposed between the body and the guiding plate, the guiding plate has an upper end away from the ejection opening, and the biasing mechanism abuts the guiding Leading the plate and causing the upper end to have a tendency to move toward the magazine; a striker is movably disposed in the body; an operating mechanism is movably disposed on the body, operable to cause the striker to face The nail opening moves.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Please refer to FIG. 1 to FIG. 5 to illustrate a preferred embodiment of the present invention. The nail gun 1 of the present invention includes a body 10, a nail guiding mechanism 20, a striker 30 and an operating mechanism 40. .

The body 10 has a nail opening 11 and a magazine 12, and an outlet 121 of the magazine 12 communicates with the nail opening 11 , and the outlet 121 outputs the nail 50 from the magazine 12 . The guiding mechanism 20 includes a guiding plate 21 facing the outlet 121 and a biasing mechanism 22 disposed between the body 10 and the guiding plate 21. The guiding plate 21 has a distance from the opening 11 At one of the upper ends 211, the biasing mechanism 22 abuts the guide plate 21 and causes the upper end 211 to normally have a tendency to move toward the magazine 12. The striker 30 is movably disposed within the body 10. The operating mechanism 40 is movably disposed on the body 10 and is operable to move the striker 30 toward the nail opening 11. The biasing mechanism 22 can be biased against the upper end 211 to contact the striker 30. By the biasing mechanism 22, the upper end 211 normally has a tendency to move toward the magazine 12, and after the striker 30 hits the nail 50 to the nailing process, the nail 50 can be ensured to face outward without facing The magazine 12 is internally offset, so that the staple problem is not generated.

In detail, the biasing mechanism 22 includes a first elastic member 221 and a second elastic member 222 that abuts the guiding plate 21, and the guiding plate 21 further includes a lower end 212 opposite to the upper end 211. The first and second elastic members 221, 222 respectively approach and abut the upper end 211 and the lower end 212. The elastic modulus of the first elastic member 221 is greater than the elastic modulus of the second elastic member 222 to generate a biasing effect. Further, the guiding mechanism 20 further includes a base 23 disposed on the body 10, the base 23 has two sidewalls 231 disposed in parallel and oppositely disposed, and the two sidewalls 231 define a space with the guiding plate 21. 232, the biasing mechanism 22 is located in the space 232. The base 23 is pivotally connected to the body 10 at its upper end, which further ensures that the upper end 211 of the guiding plate 21 normally has a tendency to move toward the magazine 12. The first end 233 and the lower end 234 of the base 23 are respectively provided with a first socket 235 and a second socket 236 for the first and second elastic members 221, 222 respectively, so that the first and second The elastic members 221, 222 are stably disposed, wherein the first and second sockets 235, 236 can be cams or recesses. However, the biasing mechanism may include only an elastic member that abuts the guiding plate 21. The elastic member is relatively close to the upper end 211, and the biasing effect is also generated. Alternatively, the biasing mechanism can be a spring arm that is connected to the guiding plate 21 at an appropriate position, and the elastic arm has a normal posture toward the nail. The trend of 匣.

Preferably, the guiding mechanism 20 further includes at least one supporting component 24 disposed between the base 23 and the guiding plate 21, and the guiding plate 21 is further provided with at least one through slot 213, and each supporting component The bottom wall 237 is parallel to the bottom wall 237 of the guiding plate 21, and the bottom wall 237 is provided with at least one guiding groove 238 at an upper end, and each supporting component 24 includes an elastic member 241 and a supporting member 242 pivotally connected to the base 23. The elastic member 241 abuts between the bottom wall 237 and the supporting member 242. The supporting member 242 is provided with a pivotable opening. The guide shoulder 243 of the guide groove 238 guides and stabilizes the support member 242.

Specifically, the magazine 12 has a nail rail 122 extending toward the outlet 121 of the magazine 12, the nail rail 122 having a length direction and an oblique guide surface 123 adjacent to the nail opening 11, the oblique guide The guiding member 20 includes two supporting members 24, and the guiding plate 21 is provided with two through slots 213, and one of the two through slots 213 is opposite to the inner end of the magazine 12 The through slot is closed around, and the other is a slot that is open to the end of the nail opening 11 and corresponds to the oblique guide surface 123. The two slots 213 are located in the nail rail 122. On the opposite sides, the inclined guiding surface 123 allows a portion of the supporting member 242 to be introduced into the interior of the magazine 12 to meet the needs of the different specifications of the nail. By the cooperation of the two supporting members 242, the two through grooves 213 and the inclined guiding surface 123, the nails of various specifications can be simultaneously applied, such as T-shaped nails, U-shaped nails, and dowels or thick-shaped nails. .

With reference to FIGS. 6 to 9 , in actual operation, during a collision of the striker 30 toward the nail opening 11 by a power accumulating mechanism 60 , the biasing mechanism 22 pushes against the upper end 211 of the guiding plate 21 . Abutting the staples 50, the guiding plate 21 is gradually separated from the magazine 12 by the upper end 211 toward the lower end 212, so that the nail 50 faces outward without being offset toward the inside of the magazine 12, No staple problems.

In summary, the overall structural design, practicability and efficiency of the present invention are indeed fully in line with the needs of industrial development, and the disclosed structural invention is also an unprecedented innovative structure. Therefore, its "novelty" should be undoubtedly considered, and the invention can be more effective than the conventional structure, and therefore has "progressiveness", which fully complies with the requirements of the application requirements of the invention patents of the Chinese Patent Law. File a patent application in accordance with the law and ask the bureau to review it early and give it affirmation.
