Description

Technical Field

[0001] This utility model relates to the field of nailing technology, and specifically to a dual-purpose nail gun. Background Technology

[0002] In existing technologies, nail guns are typically designed for specific types of nails, such as straight nails or multi-stud nails. To accommodate various nail types, some nail guns employ a split-nailing plate structure. Patent application 202423112279.0 provides a split-nailing plate nail gun that adjusts the nail track width. However, this design often overlooks the dynamic coordination between the split-nailing plate and the firing pin when switching nail tracks. In straight nail mode, the split-nailing plate needs to be upright to separate the nail tracks, but the firing pin may interfere with the plate during impact, leading to decreased impact accuracy, firing pin wear, or damage to the split-nailing plate. In multi-stud nail mode, the split-nailing plate needs to be lifted to make way for the nail track, but existing designs lack an effective avoidance mechanism, potentially causing accidental contact between the firing pin and the split-nailing plate, affecting impact efficiency. Therefore, there is an urgent need for a design that can dynamically coordinate the movement of the split-nailing plate and the firing pin to improve the reliability and versatility of the nail gun in various operating modes. Utility Model Content

[0003] To address the existing technical problems, this utility model proposes a dual-purpose nail gun. Through the ingenious cooperation between the sliding groove on the firing pin and the nail-separating plate, it achieves precise guidance and anti-interference of the firing pin in straight nail mode, while achieving non-contact avoidance in stud nail mode.

[0004] The technical solution adopted by this utility model is as follows: A dual-purpose nail gun includes a gun head, a guide assembly, a nail magazine, a firing pin, and a nail-separating plate; the guide assembly and the nail magazine are respectively provided with U-shaped grooves; one end of the nail-separating plate is rotatably connected to the gun head, and the other end of the nail-separating plate is movably abutting against the guide assembly; the gun head is provided with a spring, and the spring abuts against the nail-separating plate to make the nail-separating plate tend to deflect towards the guide assembly; the firing pin is disposed inside the gun head, and the side of the firing pin away from the ejector plate is provided with a sliding groove, and the sliding groove is movably engaged with the free end of the nail-separating plate; when assembling a straight nail, the nail-separating plate abuts against the guide assembly, and the nail-separating plate is in a position that divides the U-shaped groove into a straight groove, at which time the sliding groove is slidably engaged with the nail-separating plate; when assembling a counterspin, when the nail-separating plate is lifted by the counterspin, the nail-separating plate disengages from the guide assembly, at which time the sliding groove disengages from the nail-separating plate.

[0005] Optionally, the nail box includes a fixed box piece and a movable box piece that slides with the fixed box piece. A first strip groove is provided between the fixed box piece and the movable box piece. The movable box piece is provided with a second strip groove that communicates with the first strip groove. The first strip groove and the second strip groove form a U-shaped groove for accommodating the ejector plate. A through hole connected to the ejector plate is provided on the side of the movable box piece away from the first strip groove.

[0006] Optionally, the guide assembly includes a fixed guide plate and a movable guide plate. One side of the fixed guide plate is fixedly connected to a fixed magazine plate, and the other side of the fixed guide plate is fixedly connected to the gun head. The movable magazine plate is fixedly connected to the movable guide plate, and the movable guide plate and the fixed guide plate form the U-shaped groove.

[0007] Optionally, the movable cartridge includes a first movable plate and a second movable plate, one end of the first movable plate and one end of the second movable plate are connected, the other end of the first movable plate is arranged parallel to the other end of the second movable plate, the first movable plate and the fixed cartridge have the first strip groove, the first movable plate and the second movable plate form the second strip groove, and the second movable plate is provided with the through hole and the screw hole connected to the movable guide plate.

[0008] Optionally, the fixing plate includes a first fixing plate and a second fixing plate arranged at an angle to the first fixing plate. The first fixing plate and the first movable plate are arranged parallel to form a first strip groove. The first movable plate and the second fixing plate are correspondingly arranged to form a third strip groove for accommodating the ejector plate. The third strip groove is connected to the first strip groove and the second strip groove to form a U-shaped groove.

[0009] Optionally, the first fixed plate has a first locking protrusion at the end away from the second fixed plate, and the first movable plate extends in a direction away from the third strip groove to form a first groove, with the first locking protrusion engaging with the first groove; the free end of the second fixed plate has a second groove, and the second movable plate has a second locking protrusion that slides with the second groove.

[0010] Optionally, the distance between the spine plate of the ejector plate and the groove wall of the third strip groove is not less than the thickness of the crown of the code pin to be pushed.

[0011] Optionally, the movable cartridge plate has a base support at one end away from the movable guide plate, and the fixed cartridge plate has a locking assembly that rotatably engages with the base support. The locking assembly includes a fixed block and a movable block that is rotatably connected to the fixed block. The fixed block is installed on one side of the fixed cartridge plate, and one end of the movable block has a handle, while the other end of the movable block has a hook. The base support has a latch that engages with the hook at one end facing the locking assembly.

[0012] The beneficial effects of this invention are as follows: When using straight nails, the nail divider plate separates the originally wide U-shaped nail track into two parallel, independent straight nail tracks. When the firing pin moves towards the nail under the action of the drive mechanism, the free end of the nail divider plate is embedded in the groove of the firing pin. The groove of the firing pin slides longitudinally along the free end of the nail divider plate, providing precise guidance and limiting for the firing pin, ensuring that it can accurately strike the straight nail in the straight nail track, while avoiding possible interference between the firing pin and the nail divider plate, thus ensuring the stability and reliability of the firing process. When using staple nails, when the U-shaped staple nail strip is pushed into the nail track, it overcomes the spring force, pushing the nail divider plate upward, causing it to rotate around the pivot and be stored in the receiving groove inside the gun head, thereby freeing up the entire nail track space to accommodate the staple nail. In this state, the free end of the nail divider plate is disengaged from the groove of the firing pin due to being pushed up. When the firing pin strikes downwards, its groove no longer contacts the nail-separating plate, thus striking the center of the nail directly without obstruction and completing the nailing operation. In this mode, the main function of the groove becomes "avoidance," ensuring the independence of the mechanism's movement after the mode switch. Attached Figure Description

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 5 As shown, this embodiment discloses a nail gun, including a gun head 1, a ejector plate 2, a nail magazine 3 and a guide assembly 4 mounted on the gun head 1. The nail magazine 3 is used to hold and transport nail strips (such as staples), and the guide assembly 4 is used to guide the nail strips and cooperate with the firing mechanism to complete the nailing operation. The ejector plate 2 reciprocates within the nail magazine 3 under the action of a spring (not shown in the figure), thereby continuously pushing the nail strips towards the outlet of the guide assembly 4.

[0021] The nail magazine 3 includes a fixed magazine plate 31 and a movable magazine plate 32. The guide assembly 4 includes a fixed guide plate 41 and a movable guide plate 42. The fixed magazine plate 31 and the fixed guide plate 41 are fixedly connected by screws to form a rigid integral structure and are mounted on the gun head 1. The movable magazine plate 32 and the movable guide plate 42 are fixedly connected by screws to form another movable integral structure. The integral structure formed by the movable magazine plate 32 and the movable guide plate 42 slides in conjunction with the fixed magazine plate 31. Specifically, the movable magazine plate 32 can slide parallel to the fixed magazine plate 31 to accommodate the nail strip.

[0022] The gun head is fixedly connected to the fixed guide plate and the second fixed plate 312 in sequence. A U-shaped groove for placing and guiding the gun nail is also formed between the fixed guide plate and the movable guide plate.

[0023] To accommodate both straight and staple strips, the gun head 1 is equipped with a staple-separating plate 6. One end of the staple-separating plate 6 is rotatably connected to the gun head 1 via a pivot structure, and the other end of the staple-separating plate 6 abuts against the movable end of the movable guide plate 42. The gun head 1 has a guide groove inside, with a spring 12 installed inside. One end of the spring 12 abuts against the bottom of the guide groove, and the other end abuts against the staple-separating plate 6, providing a downward restoring force for the staple-separating plate 6. When using straight staples, the flat surface of the movable guide plate 42 abuts against the free end of the staple-separating plate 6, dividing the wide U-shaped staple track into two parallel straight grooves, thus limiting the straight staples. When using staples, the wider staples overcome the spring force, lifting the staple-separating plate 6 and retracting it into the groove 418 of the gun cover 411, freeing up the entire staple track space.

[0024] The gun head also includes a firing pin 7 for striking nails. The firing pin 7 has a longitudinally extending groove 71 on its side facing away from the ejector plate. This groove 71 engages with the free end of the nail divider plate 6. When using straight nails, the nail divider plate 6 divides the originally wide U-shaped nail track into two parallel, independent straight nail tracks. When the firing pin 7 moves towards the nail under the action of the drive mechanism, the free end of the nail divider plate 6 embeds itself into the groove 71 of the firing pin 7. The groove 71 of the firing pin 7 slides longitudinally along the free end of the nail divider plate 6, providing precise guidance and limiting for the firing pin 7, ensuring it accurately strikes the straight nail in the straight nail track, while avoiding possible interference between the firing pin 7 and the nail divider plate 6, thus guaranteeing the stability and reliability of the firing process. When using staples, the U-shaped staple strip, as it is pushed into the staple track, overcomes the elastic force of spring 12, lifting the staple plate 6 upwards. This causes it to rotate around its axis and retract into the receiving groove inside the gun head 1, thus freeing up the entire staple track space to accommodate the staples. In this state, the free end of the staple plate 6 is disengaged from the firing pin's groove due to being lifted. When the firing pin strikes downwards, its groove no longer contacts the staple plate 6, allowing it to strike the center of the staple directly without obstruction, completing the staple driving operation. In this mode, the main function of the groove becomes "avoidance," ensuring the independence of the mechanism's movement after mode switching.

[0025] Furthermore, the movable cartridge 32 is integrally formed by bending a first movable plate 321 and a second movable plate 322. One end of the first movable plate 321 is connected to one end of the second movable plate 322, and the other end of the first movable plate 321 is parallel to the other end of the second movable plate 322. A first strip groove S1 is formed between the first movable plate 321 and the first fixing plate 311 of the fixed cartridge 31, and a second strip groove S2 is formed between the first movable plate 321 and the second movable plate 322. The first strip groove S1 and the second strip groove S2 together constitute a U-shaped groove for accommodating the ejector plate 2. The pushing part of the ejector plate 2 can slide smoothly within this U-shaped groove.

[0026] Furthermore, the second movable plate 322 is provided with a through hole 3221 for movably connecting with the tail of the ejector plate 2 via a pin or other means, so that the ejector plate 2 can move synchronously with the adjustment of the movable cartridge plate 32. The second movable plate 322 is also provided with a screw hole 3222 for fixedly connecting with the movable guide plate 42.

[0027] The fixed cartridge 31 includes a first fixed plate 311 and a second fixed plate 312 arranged approximately at right angles to the first fixed plate 311. The first fixed plate 311 and the first movable plate 321 of the movable cartridge 32 are arranged parallel to each other, jointly defining a first strip groove S1. The first movable plate 321 and the second fixed plate 312 are arranged opposite to each other, forming a third strip groove S3 between them to accommodate the spine of the ejector plate 2. The third strip groove S3 communicates with the first strip groove S1 and the second strip groove S2 respectively, and together they form a complete U-shaped guide channel surrounding the pushing part of the ejector plate 2, which greatly enhances the stability of the ejector plate 2 during movement. In order to ensure smooth sliding between the movable cartridge 32 and the fixed cartridge 31 and prevent it from coming off, the end of the first fixed plate 311 away from the second fixed plate 312 is bent inward to form a first locking protrusion 3111. Correspondingly, the first movable plate 321 extends and bends in the direction away from the third strip groove S3 to form a first groove 3211. The first locking protrusion 3111 is embedded in the first groove 3211, achieving sliding guidance on one side. The free end of the second fixed plate 312 is provided with a second groove 3121. The second movable plate 322 is provided with a second locking protrusion 3223 protruding inward. The second locking protrusion 3223 is embedded in the second groove 3121, achieving sliding guidance on the other side.

[0028] The distance between the spine plate 21 of the ejector plate 2 and the groove wall of the third strip groove S3 (i.e., the inner side of the second fixing plate 312) is designed to be no less than the thickness of the pin crown to be pushed. This design ensures that the pin crown has enough space to pass through during the pushing process and will not be squeezed or scratched by the groove wall, thereby avoiding problems such as pin jamming, pin crown deformation or paint peeling, and ensuring smooth pin feeding.

[0029] To lock the nail box after its width is adjusted, a locking assembly 5 is provided. A base support 51 is fixedly mounted on the end of the movable box plate 32 away from the movable guide plate 42. The locking assembly 5 is rotatably mounted on the fixed box plate 31 via a pin. This locking assembly includes a fixed block 52 fixed to the fixed box plate 31 and a movable block 53 rotatably connected to the fixed block 52 via a pin. One end of the movable block 53 has a handle 531 for easy operation, and the other end has a hook 532. The end of the base support 51 facing the locking assembly 5 has a latch 511 that engages with the hook 532. When locking is required, the movable box plate 32 is pushed to close, the inclined surface of the latch 511 contacts the hook 532 and lifts it up, then the hook 532 falls behind the latch 511 under its own weight, achieving locking. When unlocking is required, the handle 531 is turned to rotate the movable block 53, the hook 532 disengages from the latch 511, and the movable box plate 32 can be pulled open. This locking assembly enables quick, one-handed adjustment and reliable locking of the nail box width, greatly improving ease of operation and work efficiency.
