Detailed Description

Example one

As shown in fig. 1 to 2, the nail gun of the present embodiment has the following basic main structures: a gas power cylinder is arranged in a gun body A with a handle, a nail rolling component is arranged in a nail box component B, a nailing component C is arranged at one end of the gun body A, and the output end of the nail box component B is connected with the middle of the nailing component C through a nail conveying channel. The nail pushing reciprocating rod 10 of the power cylinder is connected with a nail pushing draw hook 9, and the nail pushing draw hook 9 is connected with a nail rolling assembly 12. The nailing part C comprises a nailing seat 5 fixedly connected with the gun body, the front end of the nailing seat 5 is provided with a depth adjusting frame 3 which forms a sliding pair with the nailing seat through a sliding groove, and the front end of the depth adjusting frame 3 is provided with a striking head 1 connected through a spiral depth adjusting mechanism. The screw depth adjusting mechanism can adjust the extending length of the depth adjusting rod 2 by means of the depth adjusting knob 4, thereby realizing the adjustment of the nailing depth. The output end of the nail box component B is hinged with an L-shaped nail pushing rocker 7 through a shaft sleeve 8, one end of the nail pushing rocker 7 is provided with a guide wheel 6 constrained on the depth adjusting frame 3, and the other end of the nail pushing rocker 7 is abutted against the extending end of a nail pushing reciprocating rod 10. The nail pushing resistance is obviously reduced because the nail pushing movement is transmitted by a rolling friction pair such as a guide wheel. The inner end of the nail-pushing reciprocating rod 10 abuts against a return spring 11 located in the power cylinder, and thus has a tendency to extend. One side of the extending end of the nail pushing reciprocating rod 10 is provided with a nail pushing draw hook 9, and the extending end of the nail pushing draw hook 9 extends towards the side direction to form a hook head which hooks the plastic card slot of the nail rolling component in the nail conveying channel.

When the nail pushing device is operated, the handle part of the nail coiling gun is held to press the gun body downwards, the touch head 1 and the depth adjusting frame 3 retract towards the direction of the gun body, the nail pushing rocker 7 is driven to overcome the extension trend and press the nail pushing reciprocating rod 10 downwards, the reset spring 11 is compressed to store energy, the nail pushing draw hook 9 moves backwards by the distance of the nail coiling component card slot to hook the card slot of a nail to be conveyed to the nailing position, and the nail pushing preparation is well made (see fig. 3 and 4). When the nail coiling gun is triggered to enable the firing pin to strike the nail to punch the target object to complete the nailing action, after the nail coiling gun finishes the striking of the previous nail position, along with the forward extension resetting of the triggering head 1, the nail pushing rocker 7 loses the pressing effect, the nail pushing reciprocating rod 10 returns to the extending position under the action of the resetting spring 11 and drives the nail pushing draw hook 9 to move forwards by the distance of the card slot of the nail coiling assembly 12, and the nail in the previously clamped card is transferred to the nailing position (see fig. 5 and 6); meanwhile, the reset acting force of the nail pushing reciprocating rod 10 is transmitted to the depth adjusting frame 3 through the guide wheel 6 and then transmitted to the touch head 1 through the depth adjusting rod 2, so that the touch head 1 is ensured to return to the initial position for the next nailing operation.

Tests prove that the nail rolling gun of the embodiment has high automation degree of the nail pushing mechanism, has stable and reliable performance due to simple and reasonable structure, can circularly reciprocate, and continuously and automatically complete the one-by-one nail rolling pushing operation in the nailing operation process; particularly, the nail pushing action is derived from the original operation action, and no additional operation is needed, so that the nail pushing device is very convenient and fast.
