The present invention relates to a nail gun with a hidden nail head structure.
Pneumatic nail guns, also known as pneumatic nailers, use air pressure generated by air pumps (air compressors) to drive the reciprocating movement of a piston striker in the nail gun cylinder, driving nails from the nail magazine into objects or shooting them out, thus realizing the nailing operation. In the structure of existing pneumatic nail guns, the nail head is basically fixed directly at the front end of the gun body, and the nail magazine is fixed at the bottom of the nail head. Due to the complexity of the nail head part structure (see
In view of the above-mentioned shortcomings, the present invention provides a nail gun with a hidden nail head structure. To achieve the above purpose, the present invention provides a nail gun with a hidden nail head structure, comprising a gun body, a nail magazine, and a nail head located at the nail exit of the nail magazine. The nail magazine is a component for supplying nails, the gun body is a component for striking nails, and the gun body has a connecting part extending towards the nail exit. The nail head is fixedly connected to the nail magazine on both sides by fasteners, and the upper part of the nail head is fixed to the connecting part by fasteners, realizing the hidden installation of the nail head; By adopting an insertion-type installation method, the nail head is hidden, making the overall appearance of the nail gun more elegant and attractive, with convenient assembly and connection, a more stable structure, simplified nail head structure, more convenient processing of components, and reduced manufacturing costs.
As a further improvement of the scheme, the nail magazine comprises two shell plates detachably connected, and both the inner and outer sides of the nail head have integrally formed two first screw columns and one second screw column. The two first screw columns are connected by a rib, and the second screw column is located between the two first screw columns and maintains verticality with the rib. Both shell plates are formed with a first accommodating chamber and a second accommodating chamber, the first accommodating chamber is used to accommodate the first screw columns and the rib, and the second accommodating chamber is used to accommodate the second screw column.
In the above technical solution, the nail magazine adopts a split design, and both shell plates have a first accommodating chamber and a second accommodating chamber, providing good containment for the first screw column, rib, and second screw column, improving the assembly accuracy between the nail head, nail magazine, and gun body, and facilitating the positioning and installation of the nail head, resulting in a more compact and reasonable nail exit structure.
As a further improvement of the scheme, the two shell plates are made of lightweight composite material, one end of the two shell plates is formed with a groove and connected by a spring clip embedded in the groove, and the other end of the two shell plates is connected by a screw.
In the above technical solution, the use of lightweight material effectively reduces the weight of the entire nail gun, making it easier to extend the working time and relieve fatigue. The spring clip is embedded in the groove through elastic deformation, and during the subsequent use of the nail gun, the lasting elastic force of the spring clip ensures that the two shell plates remain closely attached, ensuring the stability of the overall structure of the nail magazine by using the spring clip fastening method at one end.
As a further improvement of the scheme, the gun body includes a safety frame, and the nail magazine is equipped with a nail push plate, a limiting block, and a limiting block reset spring. When the nail push plate reaches the high position, it can drive the limiting block to move upward, restricting the movement of the safety frame, and preventing the nail gun from empty firing.
In the above technical solution, when there is a lack of nails, the safety frame cannot move, preventing the nail gun from empty firing and damaging the surface of the object.
As a further improvement of the scheme, a nail-fixing device is provided on the nail head to prevent the nails to be shot from falling out of the muzzle position. In the above technical solution, the nail-fixing device can be a magnet, which has an adsorption effect on the top nail of the row. During the nailing process, if the top nail of the row separates before nailing, the magnet can also adsorb the separated single nail, preventing the separated single nail from sliding out.
The beneficial effects of the present invention compared to the prior art are: adopting an insertion-type installation method, hiding the nail head, making the overall appearance of the nail gun more elegant and attractive, convenient assembly and connection, more stable structure, simplified nail head structure, more convenient component processing, and reduced manufacturing costs; the nail magazine adopts a split design, both shell plates have a first accommodating chamber and a second accommodating chamber, providing good containment for the first screw column, rib, and second screw column, improving the assembly accuracy between the nail head, nail magazine, and gun body, and facilitating the positioning and installation of the nail head, resulting in a more compact and reasonable nail exit structure; using the spring clip fastening method at one end of the nail magazine ensures the stability of the overall structure of the nail magazine; the nail gun has an anti-empty firing function.
