Description

Technical Field

[0001] This utility model relates to the field of nailing equipment technology, specifically to a nail box. Background Technology

[0002] Nail guns, as efficient and convenient fastening tools, are widely used in construction, decoration, and packaging industries. One of their core functions is to continuously and stably push the arranged staples to the firing position through the staple feed assembly. The structural design of the staple feed assembly directly affects the reliability, applicability, and user experience of the nail gun.

[0003] In existing technical solutions, the "nail feeding assembly for a nail gun" disclosed in authorized patent 202423112220.1 typically includes a magazine forming a U-shaped groove and a top plate that slides within the groove. A significant feature of this technology is that the connecting through hole for connecting the top plate and the magazine is located between the first channel and the third through groove of the U-shaped groove. This layout means that the mechanical structure required to connect the top plate will inevitably occupy the internal space between the two side walls of the U-shaped groove.

[0004] This design is suitable for feeding wider staples because the staples themselves have a larger crown span, sufficient to accommodate the width occupied by the connecting structure. However, when users need to handle more delicate workpieces or use fastening scenarios with varying strength requirements, narrower staples are often used. At this point, the limitations of this existing design become apparent. Because the connecting structure occupies valuable width space, the second movable plate cannot be made narrow enough, making the entire staple feeding assembly unable to adapt to and accommodate narrow staples, greatly limiting the tool's versatility. Utility Model Content

[0005] To address the technical problem that existing nail guns are only suitable for wider nails, this invention proposes a nail box. By setting the through hole of the connecting pin plate on the side of the second box away from the first strip groove, i.e. the outside of the U-shaped groove, the second box in this solution can be manufactured to be narrower, thereby successfully adapting to and reliably pushing narrow nails.

[0006] The technical solution adopted by this utility model is as follows: a nail box, including a first box body and a second box body that slides with the first box body, a first strip groove between the first box body and the second box body, the second box body having a second strip groove communicating with the first strip groove, the first strip groove and the second strip groove forming a U-shaped groove for accommodating a pin plate, and a through hole for connecting with the pin plate on the side of the second box body away from the first strip groove.

[0007] Optionally, the second casing includes a third casing plate and a fourth casing plate, one end of the third casing plate and one end of the fourth casing plate are connected, the other end of the third casing plate and the other end of the fourth casing plate are arranged parallel to each other, the third casing plate and the first casing have the first strip groove, the third casing plate and the fourth casing plate form the second strip groove, and the fourth casing plate is provided with the through hole.

[0008] Optionally, the fourth magazine plate is provided with screw holes for connection with the gun head.

[0009] Optionally, the first housing includes a first housing plate and a second housing plate arranged at an angle to the first housing plate. The first housing plate and the third housing plate are arranged parallel to each other to form a first strip groove. The third housing plate and the second housing 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.

[0010] Optionally, a first locking protrusion is formed at the end of the first casing plate away from the second casing plate, and the third casing plate extends in a direction away from the third strip groove to form a first groove, wherein the first locking protrusion and the first groove cooperate.

[0011] Optionally, the free end of the second box plate is provided with a second groove, and the fourth box plate is provided with a second latching protrusion that slides in conjunction with the second groove.

[0012] Optionally, the second casing plate is fixedly mounted with a first connecting component, and the fourth casing plate is fixedly provided with a second connecting component that movably cooperates with the first connecting component.

[0013] Optionally, the first connecting component includes a mounting plate and a hook plate. One end of the mounting plate is fixedly connected to the second box plate, and the other end of the mounting plate is rotatably connected to the hook plate. The second connecting component is provided with a slot that mates with the hook plate.

[0014] Optionally, one end of the hook plate is a handle, and the other end of the hook plate is provided with a hook. The part of the hook plate located between the handle and the hook is rotatably connected to the mounting plate via a rotating shaft.

[0015] Optionally, the second connecting assembly includes a base and a limiting plate. The base is fixedly connected to the fourth box plate. The base has a cavity for accommodating the limiting plate. The slot is formed between the lower bottom surface of the limiting plate and the upper surface of the base plate.

[0016] Optional,

[0017] The beneficial effects of this invention are as follows: By setting the through hole of the connecting pin plate on the side of the second housing away from the first strip groove, i.e., on the outer side of the U-shaped groove, the connecting structure of the pin plate is completely separated from the internal accommodating space of the U-shaped groove. Since the connecting structure no longer encroaches on the width space of the U-shaped groove, the second housing in this design can be manufactured to be narrower, thus successfully adapting to and reliably pushing narrow-width staples, significantly improving the versatility and market applicability of the staple box. At the same time, this design maintains the smooth and stable movement of the pin plate within the U-shaped groove, ensuring the reliability of staple feeding. Attached Figure Description

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 4As shown, this embodiment discloses a staple holder, particularly suitable for narrow staples with a width of less than 10mm. The staple holder mainly consists of two parts: a first holder body 100 and a second holder body 200. The first holder body 100 and the second holder body 200 are connected by a sliding fit, forming a first strip groove 310 that extends through the length of the staple holder. The second holder body 200 itself is provided with a second strip groove 320, which communicates with the first strip groove 310 in cross-section, together forming a roughly U-shaped channel 300. This U-shaped channel 300 is used to accommodate and guide the back-and-forth movement of the ejector plate 600. The through hole 210 for connecting the ejector plate 600 is located on the side of the second holder body 200 away from the first strip groove 310 (i.e., the outer side). This layout ensures that the connection point of the ejector plate 600 is completely located outside the U-shaped channel 300, without encroaching on the accommodating space of the U-shaped channel 300. Therefore, the width of the second holder body 200 (i.e., the width of the ejector plate 600) is... Figure 3 The dimensions (in the left and right directions) can be made very narrow, thus accommodating and pushing narrow code pins.

[0025] The second housing 200 is integrally injection molded from a third housing plate 220 and a fourth housing plate 230. One end of the third housing plate 220 is connected to one end of the fourth housing plate 230, forming a generally L-shaped structure, such that the other ends of the third housing plate 220 and the fourth housing plate 230 are parallel. A first strip groove 310 is formed between the first housing 100 and the third housing plate 220. A second strip groove 320 is formed between the third housing plate 220 and the fourth housing plate 230. A through hole 210 is provided on the fourth housing plate 230. One end of the ejector plate can extend into the U-shaped groove 300, and the connecting part (such as a protrusion) on the ejector plate is connected to a quick-release pin through the through hole 210 to fix the ejector plate to the second housing 200.

[0026] The first housing 100 includes a first housing plate 110 and a second housing plate 120 arranged at approximately a 90-degree angle to the first housing plate 110. The first housing plate 110 is parallel to and opposite the third housing plate 220 of the second housing 100, and the gap between them forms the aforementioned first strip groove 310. Simultaneously, the third housing plate 220 is opposite to the second housing plate 120 of the first housing 100, and the gap between them forms a third strip groove 330. This third strip groove 330 communicates with the first strip groove 310 at the top and with the second strip groove 320 at the side. Together, they form an enclosing U-shaped groove 300, encompassing all three sides of the ejector plate, greatly improving the stability and guiding accuracy of the ejector plate during high-speed reciprocating motion. The width of the third groove 330 is designed to be greater than the thickness of the spine plate of the ejector plate, ensuring that the ejector plate has sufficient room to move within the third groove 330. The spine plate of the ejector plate will not come into close contact or rub against the groove wall. This provides extra space for the crown part of the staples to accommodate and move, effectively avoiding the phenomenon of "stack squeezing" or "stack jamming" caused by insufficient space, and ensuring the continuity and smoothness of the staple feeding process.

[0027] To ensure smooth and precise relative sliding between the first housing 100 and the second housing 200, a first locking protrusion 111 extends outward from the end of the first housing plate 110 away from the second housing plate 120. Correspondingly, a first groove 221 is recessed on the third housing plate 220 in the direction away from the third strip groove 330 (i.e., outward). During assembly, the first locking protrusion 111 is precisely embedded in the first groove 221, forming the first sliding guide pair. At the same time, a second groove 121 is provided at the free end of the second housing plate 120 (i.e., the end away from the first housing plate 110). On the fourth housing plate 230, a second locking protrusion 231 protrudes inward. The second locking protrusion 231 and the second groove 121 slide together, forming the second sliding guide pair. These two sets of convex and concave mating structures provide precise guidance at the upper and lower positions of the nail box, effectively preventing the first box 100 and the second box 200 from twisting, misaligning or separating during sliding, thus ensuring the structural rigidity and reliability of the entire nail box under long-term use.

[0028] To facilitate mounting and maintenance, a quick-locking and releasing connecting assembly is used between the first housing 100 and the second housing 200. The first connecting assembly 400 is fixedly mounted on the second housing plate 120. It includes a mounting plate 410 and a hook plate 420. The mounting plate 410 is fixed to the second housing plate 120 with screws. The middle of the hook plate 420 is rotatably connected to the mounting plate 410 via a pivot 430. One end of the hook plate 420 has a handle 421 for easy manual operation, and the other end has a locking hook 422. The second connecting assembly 500 is fixedly mounted on the fourth housing plate 230. It includes a base 510 and two limiting plates 520. The base 510 is fixed to the fourth housing plate 230 with screws. The two limiting plates 520 are fixed parallel to the base 510, forming a slot 530 between them and the base plate of the base 510. When it is necessary to lock the first housing 100 and the second housing 200, simply rotate the hook 422 end of the hook plate 420 downwards so that it engages with the slot 530 of the second connecting assembly 500. Due to the leverage effect of the rotating shaft 430, the hook 422 will tightly engage with the limiting plate 520, achieving a secure lock (as shown in the image). Figure 4 (As shown). When it is necessary to separate the two for nailing, pull the handle 421 upwards to disengage the hook 422 from the slot 530, allowing the second cartridge 200 to slide out of the first cartridge 100. In use, first insert the ejector plate into the U-shaped groove 300 of the first cartridge 100, then slide the second cartridge 200 onto the first cartridge 100 through the engagement of the first protrusion 111 with the first groove 221 and the second protrusion 231 with the second groove 121. Next, align the connecting part of the ejector plate with the through hole 210 on the second cartridge 200 and connect them via a pin. Finally, pull the hook plate 420 of the first connecting assembly 400 so that its hook 422 engages with the slot 530 of the second connecting assembly 500, completing the assembly of the entire nail cartridge. For nailing, simply open the connecting assembly and slide out the second cartridge 200.
