Description
Technical Field
[0001] The utility model relates to a pneumatic nail gun, in particular to a nail box assembly of a pneumatic coil nail gun. Background Art
[0002] Pneumatic nail guns, also known as pneumatic nailers, use air pressure generated by an air pump (compressor). This high-pressure gas drives the firing pin in the gun's cylinder to hammer, driving the nails in the clamp into an object or ejecting them. A pneumatic nail gun consists of a gun body assembly and a nail magazine assembly. The gun body assembly comprises the gun body, cylinder, balancing valve, switch assembly, firing pin assembly (gun tongue), cushion, nozzle, and gun slot. The nail magazine assembly of existing pneumatic nail guns features a nail feed tray with multiple feed positions to accommodate nails of varying lengths. The complex design of the nail magazine assembly makes adjusting the feed tray's positions difficult, making operation inconvenient and significantly impacting the efficiency of these pneumatic coil nail guns. Summary of the Invention
[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a nail box assembly for a pneumatic nail gun with a simple structure, high working efficiency, convenient operation, and stable and reliable performance.
[0004] To achieve the above-mentioned purpose, the utility model adopts a nail box assembly of a pneumatic nail gun, including a nail box, a cover body arranged on the nail box, and a nail support plate gear adjustment component arranged in the nail box. The nail support plate gear adjustment component includes a positioning core shaft arranged in the nail box, a nail support plate rotatably arranged on the positioning core shaft, a positioning member linked to the nail support plate and matched with the positioning core shaft, and a tension spring arranged between the nail support plate and the positioning core shaft. A plurality of gear positioning grooves are respectively provided on the outer peripheral wall of the positioning core shaft in the axial direction, and a positioning protrusion is provided on the positioning member to match the plurality of gear positioning grooves. The positioning protrusion moves with the positioning member and is respectively engaged in the plurality of gear positioning grooves, and constitutes a limiting match between the positioning member and the positioning core shaft.
[0005] The beneficial effect of the above structure is that the nail tray position adjustment assembly is provided within the nail magazine, thereby enabling multiple adjustment positions of the nail tray, making operation more convenient. During operation, the nail tray is pulled upward, stretching the tension spring, and then rotating the nail tray, which drives the positioning member to rotate. The positioning member's positioning protrusion engages with the position positioning groove of the positioning mandrel, thereby adjusting the position of the nail tray. As a result, the nail tray assembly of the pneumatic nail gun has the advantages of simple structure, high operating efficiency, convenient operation, and stable and reliable performance.
[0006] Specifically, a first spring seat cooperating with a tension spring is arranged on the positioning mandrel. One end of the tension spring passes through the positioning mandrel and is connected to the first spring seat. A second spring seat cooperating with the tension spring is arranged on the nail supporting plate. The other end of the tension spring passes through the nail supporting plate and is connected to the second spring seat. By arranging the first spring seat connected to the tension spring on the positioning mandrel and the second spring seat connected to the tension spring on the nail supporting plate, the assembly of the tension spring with the positioning mandrel and the nail supporting plate is facilitated, and the assembly efficiency is higher.
[0007] Specifically, two bumps are symmetrically arranged on the positioning member. Two clamping grooves cooperating with the two bumps are arranged on the nail supporting plate. The two bumps are clamped in the two clamping grooves, forming a clamping fit between the two bumps and the nail supporting plate. The positioning member and the nail supporting plate are connected by a clamping fit method, which facilitates the assembly of the positioning member and the nail supporting plate, improves the assembly efficiency, and ensures a more compact connection between the positioning member and the nail supporting plate.
[0008] Specifically, a positioning pin shaft cooperating with the cover body is arranged on the nail box. A positioning hole cooperating with the positioning pin shaft is arranged on the cover body. The positioning pin shaft is inserted into the positioning hole, forming a rotational connection fit between the cover body and the nail box. The cover body is rotatably arranged on the positioning pin shaft of the nail box, which facilitates the assembly of the cover body and the nail box and improves the assembly efficiency.
[0009] Specifically, an insertion piece cooperating with the nail box is arranged on the cover body. A jack cooperating with the insertion piece is arranged on the nail box. The insertion piece is inserted into the jack, forming a clamping fit between the insertion piece and the nail box. The insertion piece of the cover body is inserted into the jack of the nail box, which facilitates the assembly of the cover body and the nail box and makes the assembly more convenient.
