Description

Technical Field

[0001] This utility model belongs to the field of nail gun technology and relates to a nail gun nozzle and an anti-nailing structure. Background Technology

[0002] The main drawbacks of existing nail guns in preventing nail jamming are that their design and use can easily lead to nails getting stuck, affecting work efficiency and user experience. These shortcomings are usually related to the nail feeding mechanism, nail quality, and the operator's habits. An inadequate nail feeding mechanism may cause nails to misalign or bend during feeding; the nails themselves may have quality problems, such as inconsistent sizes or rough surfaces, all of which increase the risk of jamming; improper operation, such as incorrect angles or uneven force, can also cause nails to get stuck.

[0003] Conventional solutions include regularly cleaning and maintaining the nail gun to ensure the nail feed channel is free of obstructions; using high-quality nails to reduce nail jamming caused by nail defects; and training operators to standardize operating procedures. However, these methods require additional time and cost. Regular maintenance and cleaning increase preparation time before operation, and even with these measures, nail jamming cannot be completely avoided, especially in continuous operation or harsh working environments. Therefore, there is an urgent need for a nail gun nozzle and anti-jamming structure to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a nail gun nozzle and an anti-nailing structure to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a nail gun nozzle and an anti-nailing structure, comprising: an upper nozzle plate and a limiting connecting piece, wherein the lower end of the upper nozzle plate is provided with a set of lower support plates for supporting its lower end, and a set of nail outlet grooves are provided at the middle position of the upper end of the lower support plate and at the middle position of the lower end of the upper nozzle plate.

[0006] The left side of the nail outlet groove has a T-shaped cross-section. The lower end of the lower support plate is provided with a set of rear nail shells for connection with the front nail shell. The middle of the front side of the rear nail shell is provided with a nail loading groove for placing nails from the nail gun. The lower end of the inner side of the nail loading groove is provided with a set of support springs for providing support to the top nail seat. The upper end of the support spring is provided with a set of top nail seats for feeding the nails inside the nail loading groove. The top nail seats are movably and sealed with the inside of the nail loading groove. When the worker uses the nail gun, the nail is placed inside the nail loading groove, and the support spring and the top nail seat provide support for the nail. When the nail is triggered by the impact rod, the support spring provides continuous support to the top nail seat, and after the impact rod resets, it pushes the nail upward to await the second impact of the impact rod.

[0007] In a preferred embodiment, the lower front end of the rear nail row shell is provided with a set of limiting connecting pieces for fitting and limiting connection with the front nail row shell, and the front side of the limiting connecting pieces is provided with a set of front nail row shells for combined connection with the rear nail row shell.

[0008] In a preferred embodiment, the front nail rack is provided with a set of nailing boxes inside the middle of the rear side for nailing in combination with the nailing slot. The width and length of the nailing slot are the same as the length and width of the nail material used. The upper end of the rear nail rack is an integral structure with the lower support plate.

[0009] In a preferred embodiment, the lower right side of the rear pin housing is provided with a set of side connecting seats for connecting with the handlebars, the right side of the lower support plate is provided with a set of limiting brackets for connecting with the return spring, and the right side of the limiting brackets is provided with a set of return springs for resetting the trigger.

[0010] In a preferred embodiment, the reset spring has a set of reset rods inside, the reset rods pass through the limiting frame and are fixedly connected to the positioning nut, and the right side of the reset rods has a set of triggers for controlling the start of the air pump.

[0011] In a preferred embodiment, the trigger is provided with a handle for the user to hold, and the upper right side of the handle is provided with an air pump for providing impact force to the nail. The left side of the air pump is provided with a striking bar for applying force to the nail.

[0012] In a preferred embodiment, the outer side of the striking rod is provided with a set of middle shells for limiting and guiding the movement of the striking rod. The middle shells are integral with the upper end of the handle. The cross-sectional structure of the left side of the striking rod is consistent with the cross-sectional structure of the nail ejection slot and is located inside the right side of the nail ejection slot. When the air pump releases instantaneous kinetic energy to the striking rod, the striking rod can move from right to left along the right side of the nail ejection slot and knock the nail out from the left side of the nail ejection slot. At this time, the striking rod is inside the nail ejection slot, and its lower end is in contact with the upper end of the nail to be fired. When the striking rod is reset, the nail to be fired is sent into the nail ejection slot through the support spring and the top nail seat. The striking rod and the nail are perfectly matched in the nail ejection slot and the nail loading slot, respectively, thereby effectively reducing the probability of nail jamming and ensuring that the nail gun can be used stably and continuously.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: when the worker uses the nail gun, the nail is placed inside the nail slot, and the support spring and the top nail seat provide support for the nail. When the nail is triggered by the impact rod, the support spring provides continuous support for the top nail seat, and after the impact rod is reset, the nail is pushed upward to wait for the impact rod to fire a second time.

[0014] When the air pump releases instantaneous kinetic energy to the impact rod, the impact rod can move from right to left along the right side of the nail outlet groove, knocking the nail out from the left side of the nail outlet groove. At this time, the impact rod is inside the nail outlet groove, and its lower end is in contact with the upper end of the nail to be fired. When the impact rod returns to its original position, the nail to be fired is sent into the nail outlet groove through the support spring and the top nail seat. The impact rod and the nail are perfectly matched in the nail outlet groove and the nail loading groove, respectively, thereby effectively reducing the probability of nail jamming and ensuring that the nail gun can be used stably and continuously.
