Abstract

A nail gun nozzle structure comprises a base, a cover detachably disposed on the base and is provided with a nail guiding surface cooperating with the base to form a nail passage, a guiding groove concavely defined in the nail guiding surface and a concave portion concavely defined in the nail guiding surface and located adjacent to the guiding groove. The concave portion includes a nail guiding end surface abutting against an end surface of a nail head and an end surface of a nail bar, and a lateral surface connected to the nail guiding end surface and abutting against a lateral surface of the nail head. Thereby, when a T-shaped nail is placed in the nail passage of the nail gun nozzle, the nail will be restricted and guided by the concave portion and hit along the concave portion stably, so as to prevent the nail from being deviated.

Description

Nail gun structure

The invention relates to a nail gun, and in particular to a gun nozzle structure of a nail gun.

A nail gun that generally has the dual function of T nail and U nail, such as the Republic of China application No. 092206626 "nailing device for nail guns", or the application for the "two-purpose nail gun structure" of the Republic of China application No. 088203052 reveal.

Referring also to FIG. 1 , a cross-sectional view of a conventionally known dual-use function nail gun is shown. The nozzle is mainly provided by a gun holder 11 and a detachably assembled to the nozzle holder 11 . The cover body 12 is composed of a cover surface 122 facing the nozzle base 11 and forming a nail path 121 with the nozzle base 11, and the guide nail surface 122 serves as a guide striker (on the figure) The guide pin surface 122 is recessed with a guiding groove 123 for guiding the striker to avoid the offset of the striker after the striker is hit, and accordingly, the striker is not used. Simultaneously moving in the guiding groove 123 and the nail path 121, the nail member can move in the nail channel 121, and when the needle is quickly moved outward, the nail member is struck, so that the nail member 13 is fired. However, it still has the following defects that need immediate improvement in actual use cases.

Since the nail channel 121 formed by the cover body 12 after being coupled to the nozzle base 11 can be used as a nail member for accommodating the nail member or the T-shaped nail member 13, for reference, the first and second figures are used. As shown, when the nail track 121 accommodates the T-shaped nail member 13, since the size of the T-shaped nail member 13 is smaller than the shape of the dome a nail member, and the T-shaped nail member 13 only abuts against the nail guiding surface 122 without any guiding structure. Therefore, the T-shaped nail member 13 easily causes the T-shaped nail member after being fired by the impacting needle. 13 offset, which affects the breaking force of the nail.

Accordingly, how to develop a gun nozzle structure of a nail gun, which can solve the above-mentioned drawbacks, that is, the motive of the present invention.

The object of the present invention is to provide a nozzle structure of a nail gun, which is mainly provided with a guide pin recessed portion of the cover body of the gun nozzle, so that the T-shaped nail member can be received by the guide pin when placed in the nail channel of the gun nozzle. Restricting and guiding the recess, after the T-shaped nail member is fired by the striker, the T-shaped nail member can be stably shot along the guide pin concave portion, thereby avoiding the T-shaped nail member from shifting and affecting The breaking force of the nail.

In order to achieve the foregoing objective, a nozzle structure of a nail gun according to the present invention is suitable for providing a nail member having a nail head and a nail rod vertically disposed on the nail head. The nozzle structure comprises: a gun holder; a cover body detachably assembled to the nozzle base, and having a guide surface forming a nail path with the gun holder, and a recessed on the guide nail a guiding groove of the surface, and a guiding recess recessed on the guiding surface adjacent to the guiding slot, the guiding recess has a guiding end surface for abutting the end surface of the nail head and the end surface of the nail rod, and a a side of the guide pin attached to the end face of the guide pin and abutting against a side of the nail head.

Preferably, the cover extension pin has a first end surface and a second end surface opposite to the first end surface, the guide surface, the guide groove, the guide end surface of the guide pin recess, and the guide The side surface of the nail of the nail recess is connected between the first and second end faces.

Preferably, the side of the guide pin of the guide pin recess is perpendicular to the end face of the guide pin.

The present invention has been described in connection with the preferred embodiments of the present invention in accordance with the accompanying drawings.

Figure 6 is a side elevational view of the embodiment of the present invention showing the state in which the T-shaped nail member is placed in the guide pin recess of the cover.

Referring to Figures 3 to 6, a nozzle structure of a nail gun according to an embodiment of the present invention is suitable for providing a nail member. In this embodiment, a T-shaped nail member 20 is taken as an example, and a plurality of T-shaped nails are used. The 20-pieces are integrally formed into a row of nails, and each of the T-shaped nail members 20 has a nail head 21 and a nail rod 22 vertically disposed on the nail head 21. The nozzle structure is mainly composed of a gun holder 30 and a cover body 40, wherein: the nozzle base 30 is locked to the magazine 50, and has two hook portions 31 and a pinhole hole 32 between the two hook portions 31, due to the gun holder 30 is a conventional member, and its structure and configuration are the same as those of the prior art, and are not the improvement points of the present invention, and therefore will not be described again.

The cover 40 is detachably assembled to the nozzle holder 30 and has a nozzle and the nozzle The seat 30 defines a nail guiding surface 42 of a nail path 41, a guiding groove 43 recessed in the nail guiding surface 42, and a guiding nail recess 44 recessed in the guiding surface 42 and adjacent to the guiding groove 43. The guide pin recess 44 has a guide end surface 441 for the end surface 211 of the nail head 21 and the end surface 221 of the nail rod 22, and a contact end surface 441 of the nail head 21 and a side surface 212 of the nail head 21 In the embodiment, the cover 40 has a first end surface 45 and a second end surface 46 opposite to the first end surface 45. The guide surface 42 and the guide The groove 43, the nail end surface 441 of the nail recess 44, and the nail side surface 442 of the nail recess 44 are connected between the first and second end faces 45, 46, and the guide nail side of the nail recess 44 The 442 is perpendicular to the nail end face 441.

Since the cover 40 is detachably assembled to the nozzle base 30 in the same manner and structure as the conventional one, the two can be combined by a quick release structure or by a screw, and the combination thereof is the same as the conventional one. It is also not a modification of the present invention, and thus the detailed structure and combination of the components will not be described in detail.

The above description is the structure and configuration description of each main component of the embodiment of the present invention.

Therefore, when the nozzle structure of the present invention is used as the receiving T-shaped nail member 20, since the present invention is particularly provided with the guide body 40, a guide pin recess 44 for the T-shaped nail member 20 is abutted, and the guide The nail end surface 441 of the nail recess 44 is provided for the end surface 211 of the nail head 21 of the T-shaped nail member 20 and the end surface 221 of the nail rod 22, and the nail side surface 442 of the nail recess 44 is provided for the nail of the T-shaped nail member 20. The side surface 212 of the head 21 abuts, so that the T-shaped nail member 20 is restrained and guided by the guide pin recess 44 when placed in the nail channel 41 of the nozzle, so that the T-shaped nail member 20 is After the striker is fired, the T-shaped nail member 20 is stably struck along the guide pin recess 44, preventing the T-shaped nail member 20 from being displaced, and affecting the breaking force of the T-shaped nail member 20.

In summary, the above embodiments and illustrations are merely preferred embodiments of the present invention. The scope of the present invention is not limited thereto, that is, the equivalent variations and modifications made by the scope of the present invention should be within the scope of the present invention.
