Description

NAILING MACHINE
Technical Field
The present invention relates to a nailing machine capable of driving a nail using an air pressure, and in particular to a nailing machine in which it is possible to recognize whether there is a connection nail in the interior of a cartridge and to enhance a work efficiency by stopping an operation of a trigger when a connection nail does not remain in the interior of a cartridge thus preventing a defective construction.
Background Art
Generally, a nailing machine is directed to one of an air hydraulic tool widely used in a furniture fabrication process and architecture interior decoration construction. The above nailing machine includes a driving cylinder, and a body which limits a driving piston reciprocating upwardly and downwardly in the driving cylinder. In a lower portion of the body, there are provided a nose portion adapted to drive a connection nail, and a cartridge adapted to guide a connection nail in the nose portion. Here, a grip adapted to guide a compressed air to the driving cylinder is integrally provided in the body in one side of the same. A cover adapted to accommodate the connection nails provided in series is provided in a lower surface or one side surface thus opening and closing the cartridge. A pressurizing plate and a pressurizing spring are provided in the interior of the cover thus pushing the connection nail in the direction of the nose portion.
However, in the conventional cartridge of the nailing machine, it is impossible to the residual quantities of the connection nails in the interior of the cartridge. In the case that the connection nails do not remain, it is impossible to check whether the connection nail remain or do not remain, for thereby causing a defective constriction. In addition, in the conventional art, it is needed to frequently open and close the cover of the cartridge during the work in order to check whether the connection nails remain or not in the interior of the cartridge.
Disclosure of the Invention
Accordingly, it is an object of the present invention to provide a nailing machine which overcomes the problems encountered in the conventional nailing machine.
It is another object of the present invention to provide an improved nailing machine in which it is possible to check whether the connection nails remain in the interior of a cartridge.
It is further another object of the present invention to provide an improved nailing machine in which it is possible to reload connection nails by stopping the operation of the trigger in the case that the connection nails do not remain in the interior of the cartridge for thereby enhancing an efficiency of a work and preventing a defective construction.
To achieve the above objects, in a nailing machine including a driving cylinder, a body having a grip adapted to limit a driving piston upwardly and downwardly moving in the driving cylinder and to guide a compressed air in the direction of the driving cylinder, and a trigger, a nose portion adapted to drive a connection nail in the lower portion of the body, and a cartridge unit which has one side opened and closed by the cover for guiding the connection nail to the nose portion, and a cartridge having a pressurizing plate and a pressurizing spring for pushing the connection nail in the direction of the nose portion, there is provide an improved nailing machine comprising a guide hole which passes through the cartridge and is formed in an upper portion of the cartridge in a lower side of the other end of the trigger; the pressurizing plate which has a certain height higher than a known connection nail; a first slanted surface which is formed in one end which pressurizes the connection nail in the side of the upper portion of the pressurizing plate; and a stop unit which has a stop bar for stopping the operation of the trigger in such a manner that the stop bar has an upper portion engaged to a lower portion of the other end of the trigger by a hinge between the body and the cartridge unit, and a lower portion provided in an inner side of the guide hole, so that the lower portion of the same is closely contacted with the upper portion of the pressurizing plate.

As shown in Figure 1, a nailing machine 100 according to a first embodiment of the present invention includes a driving cylinder(not shown), a body 10 having a grip 12 adapted to limit the driving piston(not shown) upwardly and downwardly moving in the driving cylinder and to guide a compressed air in the direction of the driving cylinder, and a trigger 14, a nose portion 20 adapted to drive a connection nail 22 in the lower portion of the body 10, and a cartridge unit 30 which has one side opened and closed by the cover 34 for guiding the connection nail 22 to the nose portion 20, and a cartridge 32 having a pressurizing plate 36 and a pressurizing spring 38 for pushing the connection nail 22 in the direction of the nose portion 20.
At this time, a guide hole 110 vertically passing through the cartridge 32 is vertically formed in the upper portion of the lower side cartridge 32 of the trigger 14. The pressurizing plate 36 is designed to have a certain height higher than a conventional connection nail 22. One end of the pressurizing plate 36 adapted to pressurize the connection nail 22 forms a first slanted surface 120 at a certain angle in the direction of the upper side of the pressurizing plate 36. A stop portion 130 is further provided in the body 10 and the cartridge unit 30 of the nailing machine
100. The stop portion 130 includes a stop bar 132 and a hinge 134. The stop bar 132 is formed in a vertical circular column shape and is disposed between the trigger 14 and the guide hole 110. The upper portion of the stop bar 132 is coupled to the lower end of the trigger 14 by a hinge 134.

When the connection nail 22 is engaged in the cartridge unit 30 in the above manner, a compressor(not shown) is connected with the grip 12 for thereby performing a desired work.
When the work is performed in the above manner, the pressurizing plate 36 continuously pushes the connection nails 22 in the direction of the nose portion 20 by the pressurizing spring 38. At this time, the upper portion of the stop bar 232 is hit by the operation of the trigger 14. As a result, the engaging portion 234 pressurizes the operation spring 242, and the lower portion of the stop bar 232 is moved down to the portion near the upper portion of the connection nail 22. When the trigger 14 is recovered, the operation spring 242 pushes the engaging portion 234. As a result, the stop bar 232 is recovered together with the trigger 14.
