Description

Technical Field

[0001] This invention relates to the field of electric nail guns, specifically an AC nail gun with a rotating structure. Background Technology

[0002] An electric nail gun is a handheld fastening tool powered by electricity, consisting of a gun body and a magazine assembly. It quickly drives nails into materials such as wood and walls for efficient fixing. Currently available electric nail guns are generally either AC-driven or DC-driven. AC-driven nail guns use an acceleration coil to drive the hammer, which moves under the influence of an electromagnetic field. The firing pin at the front pushes the nail out. However, these types of electric nail guns require more copper wire, resulting in higher production costs. Furthermore, the striking force is limited by the coil's magnetic field, and unstable voltage can lead to inconsistent striking force. DC-driven nail guns typically use a battery to power a DC motor for nailing. Batteries face many limitations when shipped, and if the battery is low, it needs to be recharged first, preventing immediate use and causing inconvenience. Summary of the Invention

[0003] In view of the shortcomings of existing electric nail guns, the technical problem to be solved by the present invention is to provide an AC nail gun with a rotating structure that is easy to use and not restricted by mailing conditions, does not require an acceleration coil, has a simple and stable structure, and is low in cost.

[0004] To achieve the above objectives, according to one aspect of the present invention, the invention is implemented through the following technical measures: a rotary AC nail gun, comprising a housing, a control structure, and an execution structure, wherein the control structure includes a main switch, a rectifier, a controller, and a nail-driving switch; the execution structure includes a gun head and a drive structure, wherein a firing pin is provided inside the gun head; the drive structure includes an AC motor, a reduction gearbox, a cam, a fixed block, and a guide rod; the AC motor is connected to the reduction gearbox, and the reduction gearbox is connected to the cam; the fixed block is fixed inside the housing and fixedly connected to the gun head; one end of the guide rod is connected to the fixed block, and the other end is provided with a nut; a buffer block, a slider, a stroke spring, and a limit plate are sequentially sleeved on the guide rod; the buffer block is fixedly connected to the fixed block; a push plate is provided on the slider; and a push rod is provided on the cam, the push rod being used to push the slider to move and compress the stroke spring.

[0005] Furthermore, the pusher plate is disposed on the slider near one end of the travel spring, and the push rod includes a short push rod and a long push rod. The short push rod pushes the pusher plate, and the long push rod pushes the bottom of the slider.

[0006] Furthermore, the number of guide rods is two.

[0007] Furthermore, the gun head is provided with a guide groove, and the actuation structure also includes a protective structure. The protective structure includes a protective rod and a small spring. The small spring is located inside the housing, with its two ends abutting against the housing and the protective rod, respectively. A sensor is provided on one side of the small spring. One end of the protective rod is sleeved inside the small spring, and the other end passes through the guide groove of the gun head and extends to the nail outlet of the gun head.

[0008] Furthermore, a protective sleeve is provided on the protective rod.

[0009] Compared with the prior art, the advantages of this invention are as follows: This rotating AC nail gun uses household AC power as its power source, can be used directly after plugging in, is convenient to use and is not restricted by mailing conditions, uses a cam to push a slider to compress a spring, and the slider strikes the firing pin under the action of the spring force to push the nail out, without the need for an acceleration coil, the structure is simple, stable and low cost; even in the case of unstable or low household voltage, as long as the AC motor can still push the travel spring, it can fire nails with the same force, and the firing effect is stable.

[0014] Please refer to Figure 1-2 This embodiment provides a rotating AC nail gun, including a housing 1, a control structure, and an execution structure. The control structure includes a main switch 2, a rectifier, a controller 3, and a nail-driving switch 4. The rectifier and controller 3 are integrated. The execution structure includes a gun head 5, a protection structure, and a drive structure. The drive structure includes an AC motor 12, a reduction gearbox 13, a cam 14, a fixing block 15, and a guide rod 16. To increase stability, two guide rods 16 are preferably provided. The control structure and drive structure are located inside the housing 1. The gun head 5 has a firing pin 6 for striking and firing the nail. The gun head 5 also has a guide groove 7 for sliding the protection rod 8. The protection structure includes a protection rod 8, a small spring 9, and a sensor 10. The small spring 9 is located inside the housing 1 and is limited and guided by the housing 1. The two ends of the small spring 9 abut against the housing 1 and the protection rod 8, respectively. A sensor 10 is located on one side of the small spring 9. One end of the protection rod 8 is fitted inside the small spring 9 and limited and guided by the gap in the housing 1, while the other end passes through the guide groove of the gun head 5. 7 extends beyond the nail outlet of the gun head 5 and is equipped with a protective sleeve 11; the AC motor 12 is connected to the reduction gearbox 13, the drive shaft of the reduction gearbox 13 is connected to the cam 14, the cam 14 is driven by the AC motor 12 after reduction, the cam 14 is equipped with a short push rod 22 and a long push rod 23, the fixing block 15 is fixed inside the housing 1 and fixedly connected to the gun head 5, one end of the guide rod 16 is fixedly connected to the fixing block 15, and the other end is limited by the nut 21, the buffer block 17 and the slider 18 are sequentially sleeved on the guide rod 16. The stroke spring 19, the limiting plate 20, the buffer block 17 and the fixed block 15 are fixedly connected. The fixed block 15 and the buffer block 17 are provided with through holes for the tail of the firing pin 6 to pass through. The slider 18 is provided with a push plate 24 at one end near the stroke spring 19. The short push rod 22 of the cam 14 pushes the push plate 24, and the long push rod 23 pushes the bottom stroke spring of the slider 18 to abut against the slider 18 and the limiting plate 20 respectively. The limiting plate 20 is limited by the housing 1. The tension of the stroke spring 19 can be adjusted by the nut 21.

[0015] This embodiment provides a rotating AC nail gun. In use, the main switch 2 is turned on, and the controller 3 is powered on, converting AC power into low-voltage DC power to supply the nailing switch 4 and sensor 10. The rectifier rectifies the current and directly powers the AC motor. The nail gun nozzle is pressed against the area to be nailed. The protective sleeve 11 is pushed by the force, pushing the protective rod 8. The protective rod 8 slides along the guide groove 7 at the gun head 5 and compresses the small spring 9. When the sensor 10 detects that the protective rod 8 has reached its position, it notifies the controller 3 to release the protection. Then, the nailing switch 4 is pressed. Upon receiving the nailing command, the controller 3 drives the AC motor 12 to rotate. After being slowed down by the reduction gearbox 13, the motor drives the cam 14 to rotate. The short push rod 22 pushes the push plate 24 on the slider 18, causing the slider 18 to move along the guide rod 16 and compress the stroke spring 19. When the short push rod 22 rotates to near the farthest pushing distance of the slider 18, the long push rod 23 rotates between the slider 18 and the buffer block 17 and continues to push the slider 18 to move against the bottom of the slider 18. At this time, the short push rod 22 and the slider 18 separate. When the cam 14 continues to rotate until the long push rod 23 slides away from the bottom of the slider 18, the slider 18 resets under the elastic force of the stroke spring 19 and strikes the tail of the firing pin 6, thereby firing the nail from the head. At this time, the short push rod 22 rotates to the vicinity of the push plate 24 of the slider 18 to wait for the next nail firing command.
