Description

Technical Field

[0001] The utility model relates to the technical field of nail gun equipment, in particular to an air defense nail gun. Background Art

[0002] A nailing machine, also known as a nail gun, uses a firing pin to drive out nails to achieve the nailing work. The nails are generally placed in a row in a magazine, and the spring seat in the magazine holds the nails to achieve continuous nailing. However, with current nailing machines, the user cannot obtain the number of nails in time before or after the nailing is completed. In particular, after the nailing is completed, a blank shot will occur when the trigger is pulled again. Frequent blank shots will bring unnecessary impact and loss to the nailing machine, thereby accelerating the wear of the nailing machine. The authorized patent CN220279559U discloses an air nail gun and its integrated magazine. Although the integrated magazine has a simple structure and high overall rigidity, the nail gun is not designed with a corresponding anti-blank shot mechanism. Utility Model Content

[0003] In view of the above problems, the utility model provides an anti-aircraft nailing gun, which effectively prevents air strikes by rotating a limit plate to engage in a limit groove, thereby preventing a safety plate from retreating to be flush with the gun mouth, resulting in failure in triggering the plate handle.

DETAILED DESCRIPTION

[0017] The utility model is described in detail below in conjunction with the accompanying drawings.

[0018] like Figures 1 to 3 As shown, this embodiment discloses an air defense nail gun, including a magazine, a gun mouth and a nail feeding assembly 3, the magazine including a first spring plate 1 and a second spring plate 2, the first spring plate 1 and the second spring plate 2 forming a through slot 19 for the movement of the nail feeding assembly 3, the gun mouth slidingly provided with a safety plate 4, the second spring plate 2 near the gun mouth rotatingly provided with a limit plate 5, one end of the limit plate 5 movably abuts against the nail feeding assembly 3, and the other end of the limit plate 5 movably cooperates with the limit slot 18 on the safety plate 4. When the nail gun is in use, the gun mouth and the safety plate 4 need to be abutted against the object to be nailed, one end of the safety plate 4 slides along the inside of the gun mouth, so that the other end of the safety plate 4 is flush with the gun mouth, and then the trigger can be pulled to complete the gun (this is because when the safety plate 4 is flush with the gun mouth, the safety pad in the trigger will be pressed down, and then the trigger can be pulled down, and the trigger will drive the safety pad to move backward, so that the safety pad will fully open the valve stem of the switch for firing, which belongs to the conventional technology of the nail gun). As the nails are gradually driven out, the nail feeding assembly 3 gradually rises. When the nail feeding assembly 3 abuts against the limit plate 5, the limit plate 5 rotates and snaps into the limit groove 18, so that the safety plate 4 cannot retreat to be flush with the gun nozzle, resulting in failure to pull the plate handle, effectively preventing empty driving and extending the service life of the nail gun.

[0019] In this embodiment, if Figure 1 and 3 As shown, the gun nozzle includes a first cover plate 6 and a second cover plate 7, the safety plate 4 is slidably connected to the second cover plate 7, one side of the second cover plate 7 is detachably connected to the first cover plate 6, and the other side of the second cover plate 7 is connected to the magazine. The safety plate 4 includes a safety body 20 and a bending plate 21, the second cover plate 7 is provided with a clamping protrusion 22 on one side facing the first cover plate 6, the safety body 20 is provided with a clamping groove 23 that slidably cooperates with the clamping protrusion 22, a channel for the passage of gun nails is provided between the safety body 20 and the first cover plate 6, and the bending plate 21 is bent toward the direction where the limit plate 5 is located. The upper surface of the safety body 20 is flush with the highest point of the clamping protrusion 22.

[0020] In this embodiment, if Figure 1 and 2 As shown, the limit plate 5 is installed on the second spring plate 2 through the rotating shaft 8, and the rotating shaft 8 is wound with a torsion spring 9, and the two ends of the torsion spring 9 are respectively connected to the second spring plate 2, and the limit plate 5 is provided with a groove 10 that movably abuts against the nail feeding assembly 3. The rotating shaft 8 is rotatably installed on the second spring plate 2, and the limit plate 5 is fixedly connected to the rotating shaft 8. As the nails are gradually driven, the nail feeding assembly 3 rises to the position of the limit plate 5 and abuts against the groove 10, so that the limit plate 5 rotates to abut against the bending plate 21, and the safety plate 4 is limited. After the nails are reloaded, the nail feeding assembly 3 descends, and the limit plate 5 is reset under the action of the torsion spring 9, and the limit on the bending plate 21 is released.

[0021] In this embodiment, if Figure 2 As shown, the nail feeding assembly 3 includes a top plate 11, a coil spring 12 and a moving plate, one end of the top plate 11 is used to abut against the gun nail, the other end of the top plate 11 is rotatably connected to the moving plate, one end of the coil spring 12 is fixedly connected to the first spring plate 1 or the second spring plate 2, the other end of the coil spring 12 is wound on the moving plate, and a spring is provided between the top plate 11 and the moving plate. The moving plate is slidably matched with the through groove 19, the moving plate includes a first moving part 13 and a second moving part 14 connected to the first moving part 13, the top plate 11 is rotatably connected to the first moving part 13, the coil spring 12 is wound on the second moving part 14, and the second moving part 14 is movably abutted against the groove 10. When nailing, first pull the movable plate to the bottom of the first spring plate 1, the coil spring 12 is stretched by force, and then the nail is placed in the through slot 19, the spring is compressed by force, and when the nail is pushed to the top of the top plate 11, the spring is reset. After the nailing is completed, release the movable plate, pull the trigger, and the nails are shot out from the gun mouth in sequence. As the number of nails decreases, the coil spring 12 drives the movable plate to move along the through slot 19 toward the gun mouth by winding, so that the nails are shot continuously. When the nails are shot, the second movable part 14 rises to the position of the limit plate 5 and abuts against the groove 10, so that the limit plate 5 rotates counterclockwise and abuts against the bending plate 21. At this time, the safety plate 4 is limited and cannot move, and then the trigger cannot be pulled. The nail feeding principle of the nail feeding component 3 can be found in the patent CN220279559U pneumatic nail gun and its integrated magazine.

[0022] In this embodiment, if Figure 3 As shown, one end of the first cover plate 6 is rotatably connected to one end of the second cover plate 7, the other end of the first cover plate 6 is provided with a hook assembly, and the other end of the second cover plate 7 is provided with a block 15 that cooperates with the hook assembly. The hook assembly includes a button 16 and a return hook 17, one end of the button 16 is rotatably connected to the first cover plate 6, the other end of the button 16 is connected to the return hook 17, and the return hook 17 cooperates with the block 15.

[0023] The button 16 drives one end of the return hook 17 to rotate toward the block 15, so that the return hook 17 is separated from the block 15, and the first cover plate 6 can be opened to check the status of the nail gun; the button 16 drives one end of the return hook 17 to rotate in the direction away from the block 15, so that the return hook 17 is tightly against the block 15, so that the first cover plate 6 and the second cover plate 7 are fixedly connected.

[0024] The above description is only a preferred embodiment of the utility model, and does not limit the patent protection scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the utility model.
