Description

Hammer gun

This creation is about a hammer-type nail gun.

In general, the hammer type nail gun disclosed in the patent TWI380884 includes a left and right two-piece housing and a nailing mechanism accommodated therein, and the sheet-shaped housing is recessed by a metal sheet body by impact or the like. Folding and punching to form are limited by the difficulty of processing the metal sheet, and the shape of the casing is rather limited. Therefore, generally only a general shape can be formed, and the nailing mechanism must be positioned with an additional fixing member.

In addition, the weight of the metal casing is quite heavy, which is a great burden for the user, and there must be a gap between the metal casing and the metal nailing mechanism, which is bound to generate huge noise when hammering. With the vibration, there is still room for improvement.

The main purpose of this creation is to provide a hammer-type nail gun that has the advantages of light weight, shock absorption and noise reduction.

In order to achieve the above object, the present invention provides a hammer type nail gun comprising a casing, a grip and a firing device.

The outer casing is injection molded from a mixture of glass fibers and nylon, wherein the mixture comprises 30% to 70% of glass fibers and 70% to 30% of nylon, and the outer ends of the outer casing are respectively a length along the length thereof. One end and a second end, the outer casing of the outer casing encloses an accommodating space, the outer casing has a bottom opening extending along the length direction and communicating with the accommodating space; the grip is connected to the outer casing The second end; the firing mechanism is made of metal and includes a nail and a hammer, the nail is disposed in the accommodating space, and the two ends of the nail are respectively a third end and a fourth The fourth end of the magazine is pivotally connected to the second end of the housing, the third end of the magazine is corresponding to the first end of the housing, and the magazine is elasticized by an elastic member to make a third The end has a tendency to move away from the outer casing, one end of the nailing member is disposed on the inner wall of the outer casing, and the other end is corresponding to the nail, and when the third end of the nail is impacted, the third end is Moving within the housing, the relative movement of the magazine and the nail member causes the The staple member in the magazine out of the staple hit.

Therefore, the hammer-type nail gun provided by the present invention is lighter in weight than the nail gun of the conventional metal casing, and the noise and vibration during the knocking are greatly reduced, and the processing cost and difficulty are also low.

The following is a description of possible implementations of the present invention by way of example only, and is not intended to limit the scope of the creation of the present invention.

Referring to Figures 1 through 6, the present invention provides a hammer-type nail gun comprising a housing 10, 10a, a grip 20, 20a and a firing mechanism.

The outer casing 10, 10a is injection molded from a mixture of glass fibers and nylon, wherein the mixture comprises 30% to 70% glass fibers and 70% to 30% nylon. Preferably, the mixture comprises 50% glass. The fiber is mixed with 50% nylon, and the glass fiber is first mixed with nylon to be granulated and then injection molded into the outer casing 10, 10a; the two ends of the outer casing 10, 10a along the length thereof are respectively a first end and a first At the two ends, the outer casing 10, 10a is surrounded by an accommodating space, and the outer casing 10, 10a is opened with a bottom opening extending along the length direction and communicating with the accommodating space; the grips 20, 20a are connected to The second end of the outer casing 10, 10a, the grip 20, 20a is made of plastic, rubber or silicone; the firing mechanism is made of metal and includes a magazine 31, 31a and a nail member 32, 32a, the magazines 31, 31a are disposed in the accommodating space, and the two ends of the magazines 31, 31a in the longitudinal direction are respectively a third end and a fourth end, and the fourth end of the magazine 31, 31a Connected to the second end of the outer casing 10, 10a, the third end position of the magazine 31, 31a corresponds to the outer casing 1 At the first end of 0, 10a, the magazines 31, 31a are subjected to an elastic force of an elastic member 33, 33a such that the third end thereof has a tendency to move away from the outer casing 10, 10a. Preferably, the elastic member 33 33a is a spring piece, and one end of the elastic piece is fixed on one side of the inner wall of the outer casing 10, 10a facing the nail 31, 31a, and the other end is abutted against the nail 31, 31a. One end of the nailing piece 32, 32a is provided. The inner wall of the outer casing 10, 10a is at the other end corresponding to the magazine 31, 31a. When the third end of the magazine 31, 31a is impacted, the third end is moved into the outer casing 10, 10a. The relative movement of the jaws 31, 31a with the nail members 32, 32a causes the nail members 32, 32a to strike the staples in the magazines 31, 31a outward.

Further, in the first embodiment of the present invention, as shown in FIGS. 1 to 3, the grip 20 is sleeved at the second end of the outer casing 10 and extends to the first end and the second end of the outer casing 10. And a predetermined abutment of the outer casing 10 at a predetermined distance from the second end, the abutting portion abuts against the lower end of the magazine 31, so that the magazine 31 cannot pivot downward without limitation, and In this embodiment, the magazine 31 is formed by a combination of a limiting rail and a nail rail. The limiting rail is disposed above the nail rail and pivotally connected to the housing 10. The nail rail is filled with a nail. And can be pulled back from the second end of the outer casing 10 to replenish the nail. The outer casing 10 has a positioning member adjacent to the abutting portion, and the positioning member is selectively inserted into a positioning hole of the nail rail to block the The nail rail is pulled back.

In the second embodiment of the present invention, as shown in FIGS. 4 to 6, the second end of the outer casing 10a further extends away from the first end, and the grip 20a is sleeved at the end, that is, It is said that the magazine 31a is substantially pivoted in front of the gripper 20a, and the magazine 31a is similar in structure to a stapler of a general stationery, wherein the nailer 32a is formed with a long groove, and the magazine 31a is formed with a bump. The protrusion passes through the long groove and can linearly slide in the long groove, and the maximum pivoting angle of the magazine 31a is restricted by the long groove and the protrusion.

In summary, the hammer-type nail gun provided in the present invention achieves the effects of weight reduction, noise reduction and shock absorption by a special material casing, and the injection molding shell has a simple process and low cost, and is equipped with a pivot pin. A hammer-type nail gun with an extremely simple structure and durability is provided.
