Description

  The present invention relates to a nail gun, and more particularly to a highly safe nail gun.

A nail gun is a device that continuously nails a property. Mainly, there is a striking piece that slides up and down on the front edge of the shell that covers the lid, and a continuous nail body that is driven by the compressor at the bottom edge of the shell and intersects with the striking piece perpendicularly. . When the striking piece is actuated to move upward and release the striking piece, the striking piece instantly fires the nail body downward. Such nail guns are widely used because they are easy to operate and efficient.

  Taking a manual nail gun as an example, when a nail gun is not in use, a ring that serves as a safety device is generally installed on the shell to prevent the nail from hitting due to a malfunction. In practice, however, the ring must first be released in the course of use, increasing operational inconvenience, and once released, the nail gun is immediately fired, Even when the nail gun does not adhere to the surface of the work object, there is a possibility that the user may fire a hitting piece due to misfiring.

Accordingly, an object of the present invention is to provide a highly safe nail gun that prevents erroneous shooting.

  The nail gun of the present invention comprises a shell, a striking piece, and a safety structure. The shell holds other elements. The striking piece is installed at the front edge of the shell, and can be lifted and released by the pressure rod installed on the shell, and has a spring piece that connects the striking piece inside the shell, and the pressure rod strikes When releasing the piece, the striking piece is fired downward under the action of the spring piece. The safety structure is installed in front of the shell striking piece, is slid on the pressure element on the front edge of the shell, and the pressure element slightly protrudes from the bottom surface of the shell, but does not escape completely. Further, a braking element is pivoted above the resistance element, and both ends of the pivot point of the braking element correspond to the resistance element and the striking piece, respectively. Furthermore, the braking element is provided with a restoring element corresponding to the upper side of the resistance element, and the resistance element projects downward from the bottom surface of the shell under normal conditions. The other end of the braking element restricts the upward movement of the striking piece. When the pressure-compensating element is compressed into the shell, the braking element is actuated so that one end corresponding to the striking piece rotates downward. The striking piece is released, and the braking element is rotated and operated upward so that the striking piece is not released.

  According to the present invention, the braking element of the nail gun restricts the upward movement of the striking piece when the pressure element is not retracted into the shell, so that when the nail gun does not stick to the operation plane, the striking piece It is possible to ensure safety in the process of using the nail gun without being in a fired state.

As shown in FIGS. 1 and 2, the highly safe nail gun according to the present invention includes two shells 10 that cover each other, a striking piece 15 installed at the front edge of the shell 10, and a striking piece 15. The safety structure 20 which can selectively restrict | limit upward movement is comprised.

  In a preferred embodiment of the nail gun according to the present invention, as shown in FIGS. 1 to 3, both shells 10 have opposed front pieces 11, and a slot in which a striking piece 15 slides in the front piece 11. 12 is formed. The lower stage of the slot 12 has a track piece 13 to increase the stability when the striking piece 15 slides and the service life of the shell 10. Further, the bottom edges of both shells 10 have a nail tank 18 in which a nail body 30 is placed.

  Further, the hitting piece 15 slid in the slot 12 and the track piece 13 of both shells 10 hits the nail body 30 that is continuously crossed vertically (shown in FIG. 3). The upper stage of the striking piece 15 has an opening 150, and a spring piece 16 that strongly pushes the striking piece 15 downward is installed between the shells 10. Further, a pressure rod 17 that is manually operated is pivoted between the shells 10. In the present invention, manual operation is the main embodiment, and the front end of the pressure rod 17 has a pick 170 that is caught in the opening 150 of the striking piece 15. The pressure rod 17 lifts the striking piece 15 by the pick 170 and reaches a predetermined altitude. At this time, the pick 170 of the pressure rod 17 releases the striking piece 15, and the striking piece 15 receives the action of the spring piece 16 to fire the nail body 30 downward.

  The safety structure 20 includes a resistance element 21, a braking element 23, and a return spring 25, and the resistance element 21 is slid into the front piece 11 of both shells 10, and both shells 10 have opposite slots 22. Then, the resistance element 21 moves coaxially with the striking piece 15. Further, the side sides where the slot 22 and the resistance element 21 are adjacent to each other form opposing stop portions 220 and 210, so that the resistance element 21 moves relative to the shell 10 local area and completely escapes. There is nothing to do. The stop portions 220 and 210 of the present invention mainly have opposing convex blocks and a long concave tank, the resistance element 21 protrudes downward from the bottom surface of the shell 10 under normal conditions, and the local portion is Shift upwards. Further, the braking element 23 is pivotally disposed above the counter pressure element 21 and the striking piece 15 of the shell 10 by the pivot 24, and one end of the braking element 23 corresponding to the striking piece 15 pivots downward. Do not pivot towards. Further, a limiting tank 27 corresponding to the braking element 23 is formed on the striking piece 15, and an end portion of the braking element 23 corresponding to the striking piece 15 can be pierced in the limiting tank 27, and an end top surface Forms a slanting surface 230, and the braking element 23 does not interfere with the downward striking motion of the striking piece 15. Further, the shell 10 forms a container tank 26 above the slot 22, and the return spring 25 is installed in the container tank 26 and is positioned above the striking piece 15 one end of the brake element 23, and the brake element 23. To achieve a purpose of lifting the striking piece 15 upward.

  Therefore, when the nail gun is not adhered to the object surface, the retraction spring 25 restrains the braking element 23 downward and fits in the restriction tank 27 of the striking piece 15, and the striking piece 15 does not move to the firing position. , It is possible to prevent accidental fire due to an erroneous operation.

  In actual operation of the present invention, first, when the nail gun does not adhere to the surface of the object, the braking element 23 of the safety structure 20 receives the pressure of the restoring spring, as shown in FIGS. One end corresponding to the striking piece 15 of the braking element 23 is penetrated into the restricting tank 27 by causing the resistance element 21 to protrude from the shell 10 and thereby the user pushes the pressure rod 17 downward. At this time, the pick 170 of the pressure rod 17 is caught in the opening 150 of the striking piece 15 and the striking piece 15 moves a little upward, but the braking element 23 to which the bottom surface of the restriction tank 27 of the striking piece 15 is stuck is When corresponding to the end bottom surface of 15, the braking element 23 cannot pivot upward, the safety mechanism is closed, and effectively restricts the striking piece 15 from continuing to move to a predetermined firing position. (Shown in FIG. 5) and the nail gun is on the object surface. Under normal circumstances which are not in contact, it is possible to prevent the misfiring due to an erroneous operation.

  Furthermore, the state when the nail gun is stuck to the object surface and the nail driving operation is executed is shown in FIGS. 6 to 8, and when the user sticks the nail gun to the object surface and hits the nail, FIG. 6, the resistance element 21 of the safety structure 20 is retracted into the shell 10, thrusts the braking element 23, rotates upward, and simultaneously compresses the upper return spring 25. The other end of the braking element 23 generates a recovery force and detaches the restriction tank 27 of the striking piece 15 (shown in FIG. 6) to activate the safety mechanism. When the pressure rod 17 is pushed downward, the pick 170 of the pressure rod 17 is caught in the pick 150 of the striking piece 15 and moves the striking piece 15 upward to a predetermined firing position. At the same time, the spring piece 16 is swung to generate a recovery force upward (shown in FIG. 7), the striking piece 15 reaches a certain altitude, and the pick 170 of the pressure rod 17 is moved to the striking piece 15. When released from the opening 150, the striking piece 15 is fired downward by the restoring force of the spring piece 16, and the lower nail body 30 is fired by the striking piece 15 to complete the nail driving operation (FIG. 8). Indicated by). The striking piece 15, the anti-pressure element 21, and the braking element 23 are restored to their original positions to provide the next circulation operation.
