Description

Technical Field

[0001] This utility model belongs to the technical field of nail fastening equipment, specifically relating to a nail charging structure. Background Technology

[0002] In recent years, the technology of non-explosive charging has been successfully applied to nail fastening equipment. Currently, there are two main types of charging structures: two-section and "embedded". In actual use, the two-section propellant is in a tight fit in the chamber, which is conducive to ignition. To penetrate an 8 mm steel plate, the required amount of propellant is about 170 mg to 200 mg, and to penetrate a 10 mm steel plate, the required amount of propellant is about 235 mg to 245 mg. In contrast, the embedded propellant has a gap of 0.1 mm to 0.2 mm in the chamber. To penetrate an 8 mm steel plate, the required amount of propellant is about 240 mg to 260 mg. Occasionally, due to poor matching between the propellant and the cartridge, the firing rate, power, and fastening performance may decrease, and even "spike skipping" may occur. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a nail gun charging structure. In the embedded charging structure, a separation groove is prefabricated at an appropriate part of the inner liner, so that the charge can be reliably separated in the early stage of ignition, thereby effectively reducing frictional resistance and increasing power. After this improvement, the gap size of the charging chamber does not need to be strictly controlled, and the two-section and embedded types have the same power with the same amount of charge.

[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A nail gun charging structure includes a shell with an open end, an inner liner with an open end extending along the length direction inside the shell, a propellant column inside the inner liner, and a separation groove on the inner liner.

[0006] Preferably, in the described nail charging structure, the separation groove is located on the inner or outer side of the inner liner.

[0007] Preferably, in the described nail charging structure, the distance between the separation groove located on the inner side of the inner liner and the outer side of the inner liner is 2-6 mm.

[0008] Preferably, in the aforementioned nail charging structure, the separation groove has a width of 0.2~1.0mm and a depth of 0.2~0.3mm.

[0009] Preferably, in the described nail-loading structure, a nail is provided at the other end of the housing.

[0010] A nail gun charging structure includes a shell with an open end, an inner cover at one end of the shell, an open end of the inner cover, and a propellant charge disposed inside the inner cover.

[0011] Preferably, in the described nail-loading structure, a nail is provided at the other end of the housing.

[0012] Preferably, in the aforementioned nail loading structure, the inner cover has a cross-section that is either U-shaped or rectangular.

[0013] A nail gun charging structure includes a shell with an open end, a propellant charge disposed inside the shell, and a thin film disposed at the open end of the shell.

[0014] Preferably, in the described nail-loading structure, a nail is provided at the other end of the housing.

[0015] The beneficial effects of this utility model are:

[0016] The present invention relates to a nail-loading structure with a separation groove in the inner liner of the nail-loading structure, which enables reliable separation of the charge in the early stage of ignition, thereby effectively reducing frictional resistance and increasing power. After this improvement, the gap size of the charge chamber does not need to be strictly controlled, and the two-section and embedded types have the same power with the same charge. The same effect can also be achieved by replacing the inner liner inside the shell with an inner cover or a thin film. Attached Figure Description
