Detailed Description

The pneumatic nailing machine with nailing depth adjusting structure of the present invention will be further described with reference to the accompanying drawings.

The first embodiment is as follows:

referring to fig. 1-3, the pneumatic nailing machine with nailing depth adjusting structure of the present invention comprises a gun body 1, a gun head 2 mounted at the front end of the gun body 1, a gun door 3 mounted at the gun head 2, and a safety frame 4 connected with the gun body 1 in a retracting manner and disposed at the gun head 2.

It should be noted that, the safety catch 4 is connected to the gun body 1 in a retracting manner, which means that when nailing is performed, the safety catch 4 is forced to retract relative to the gun head, and the nailing depth can be determined by the retracting distance. The retraction connection to the frame 1 is achieved by means of spring body parts, which are conventional in the art and therefore not described in detail here.

The front end of the safety frame 4 is formed into a sleeve joint seat 5 with a through hole for sleeve joint of the muzzle of the gun head 2, namely, the sleeve joint seat 5 can retract along the muzzle of the gun head 2 when the safety frame 4 retracts.

In order to realize the adjustment of the nailing depth, namely the control of the retraction distance of the safety catch 4, the pneumatic nailing machine also comprises a door pin 6, two ends of which are respectively penetrated in the pin bases at the front end and the rear end of the side part of the gun head 2. Wherein, the front end pin seat and the rear end pin seat are two, one is the front end pin seat 7, and the other is the rear end pin seat 8, and the two are arranged at a certain distance.

The door pin 6 is of a split structure, and the door pin 6 of the split structure is formed by assembling and connecting a rod body 61 and a head 62. The gun door 3 is rotatably mounted on the rod body 61, and the front end of the rod body 61 extends out of the front end pin base 7 to limit and support the sleeve joint base 5 which is retracted in place. The limit bearing can be understood as a bearing and limiting function, which means that when the safety frame 4 drives the socket 5 to retract, the socket is limited by the front end of the rod body 61 after retracting to a required distance, so that the socket retracts to a proper position.

The rear end of the rod body 61 extends out of the rear end pin seat 8 and is connected with the head 62 in an assembling mode, the rear mounting end of the gun head 2 is formed with a threaded sleeve seat 9, the threaded sleeve seat 9 is connected with an adjusting screw rod 10 in a threaded mode, and the front end of the adjusting screw rod 10 is used for abutting against the head 62 of the gate pin 6.

Meanwhile, the side wall of the hole of the head part 62 is provided with an outer convex ring 15, and the outer side part of the rear end of the rod body 61 is provided with an inner concave ring groove 16 to be matched with the outer convex ring 15. With the structure, the rod body 61 can be effectively prevented from being separated from the head part 62, and the connection reliability is guaranteed.

To facilitate the entry of the rod 61 into the head 62, a chamfer is provided between the end wall and the side wall of the rear end of said rod 61 to facilitate a quick-fit connection of the rear end of the rod 61 to the head 62.

The socket joint base 5 is further provided with a side protrusion 17 to match the front end of the rod body 61 to limit and support the socket joint base 5, the side protrusion 17 of the socket joint base 5 is integrally formed, and the overall strength is guaranteed.

The rifle door 3 set up around the key seat with the cooperation rotate install in door bolt 6, around the key seat be located between the front and back end key seat, and adjacent leading end key seat 7 of putting of preceding key seat 18, adjacent rear end key seat 8 of back key seat 19.

Because the adjusting screw 10 is connected to the screw sleeve seat 9 only in a threaded manner, the abutting position of the adjusting screw 10 and the head part 62 is changed by rotating the adjusting screw 10 for a certain distance, so that the limiting and bearing position of the door pin 6 on the sleeve seat 5 is changed, and the purpose of adjusting the nailing depth is finally achieved.

Example two:

in fig. 2-3, a specific structure of the adjusting screw 10 is shown, and in this embodiment, the adjusting screw 10 includes an inner screw 101 and a knob sleeve 102.

The rear end of the knob sleeve 102 is provided with a rear end plate 11, the inner screw 101 comprises a screw rod body 12 and a screw head 13, and the screw rod body 12 penetrates through the rear end plate 11 and extends into the screw sleeve seat 9 and is in threaded connection with the screw sleeve seat 9. Screwing in and screwing out of the inner screw 101 can be realized after screwing.

The head part 13 of the screw is tightly fitted at the front end of the knob sleeve 102 and abuts against the head part 62 of the gate pin 6, and the abutting position can be changed by abutting, so that the penetrating position of the gate pin 6 on the gun head 2 can be changed as long as the inner screw 101 is rotated.

A spring 14 is sleeved on the screw rod body 12, and two ends of the spring 14 are respectively abutted against and connected with the screw head 13 and the rear end plate 11. The spring acts on the screw head 13 so that the screw head 13 is always pressed against the head 62 of the bolt 6 during nailing.

Through the matching arrangement of the inner screw 101 and the knob sleeve 102, the inner screw can be driven to act by rotating the knob sleeve when the inner screw 101 is adjusted, so that the adjustment operation is facilitated.

The foregoing is merely illustrative of the best mode contemplated for carrying out the embodiments of the present invention and is not to be construed as limiting the claims. The present invention is not limited to the above embodiments, and various changes are allowed in the specific structure thereof, as long as the changes in the claims are within the scope of the present invention.
