Description

Hammer gun

The invention relates to a hammer type nail gun.

In general, the hammer type nail gun disclosed in the patent I380884 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 object of the present invention is to provide a hammer type nail gun which has the advantages of light weight, shock absorption, noise reduction and easy processing.

To achieve the above object, the present invention provides a hammer type nail gun comprising a housing and a nailing mechanism.

The casing is formed by combining two halves of the casing, and each of the casings is formed by a mixture of glass fiber and nylon, wherein the weight percentage of the glass fiber and the nylon is 30 to 70% and 70 to 30%, respectively. An inner space is defined between the two half-shells, and a longitudinal direction perpendicular to the two half-shells is defined. The housing defines a first end and a second end along the longitudinal direction. The two half-shells collectively define an opening at the first end, and one side of the two half-shells facing each other has a positioning rib near the second end, and the positioning ribs of the two half-shells A surrounding space is defined.

The nailing mechanism is disposed in the inner space of the casing and is made of metal, and comprises a nail, a striker, a driving component and a transmission mechanism, wherein the nail is located in the positioning space and is positioned by the positioning rib Positioning, the striker is located at the opening and can be linearly slid to strike the nail. The driving member is located at the opening and away from the second end, the driving member can also linearly slide, the transmission mechanism The driving plate is coupled to the driving member for moving the collision plate and the driving member in opposite directions. When the lower end of the driving member is subjected to an upward impact, the driving member is driven to slide upward.

Thereby, since the casing of the present invention is not made of metal, but is made of a mixture of nylon and glass fiber, the weight of the casing can be greatly reduced, and the vibration and noise generated during the tapping can be reduced, and most importantly, The housing of the present invention is extremely easy to manufacture and process, and is easy to assemble, compared to a housing made of sheet metal.

In the embodiment, the driving member 23 An at least one hook hole 231 is formed. One end of the first connecting member 241 is hooked to the hook hole 231 to be connected to the driving member 23, and the elastic member 243 is received in the receiving slot and one end of the elastic member 243 is elastically engaged with the receiving slot. The bottom portion of the first connecting member 241 is located above the abutting slope 113 and is restricted to slide only in the region above the abutting slope 113.

On the other hand, the nailing mechanism 20 has at least one first fixing hole 25 through which the at least one first fixing member 30 is fixed to at least one of the housings 11 and, in addition, The two half-shells 11 respectively have at least one second fixing hole 114. The at least one second fixing member 40 passes through the second fixing holes 114 to fix the two half-shells 11 to each other, that is, when assembled. The nailing mechanism 20 is first fixed to one half of the housing 11, and the other half of the housing 11 is fixed to the half housing 11 and the nailing mechanism 20 is covered and positioned.
