Abstract
Description
Technical Field
[0001] This utility model relates to the field of nail gun cartridge technology, and in particular to a split-type nail gun structure. Background Technology
[0002] Nail gun cartridges utilize gunpowder energy to achieve rapid fastening. Specifically, the cartridge uses internal gunpowder as a power source, and a spring mechanism on the nail fastener drives the firing pin to penetrate the ignition powder inside the nail. Intense friction ignites the propellant, which in turn ignites the propellant. The resulting high-pressure gas propels the nail out at high speed, thus firmly embedding the nail into the substrate (such as concrete, steel, etc.).
[0003] In the prior art, patent publication number CN221824240U discloses an integrated nail gun structure, relating to the field of nail gun tools. This integrated nail gun structure includes a nail body and a nail cartridge; wherein, a fixing groove is formed at the tail end of the nail body, and the nail cartridge is sleeved on the tail end of the nail body and connected to the fixing groove. This integrated nail gun structure directly sleeves the nail cartridge on the tail end of the nail body, and the fixing groove connection structure improves the connection stability, preventing the two from easily separating. Furthermore, it allows the residual shell after nailing operations to be contained within the nail gun cavity, which can be removed without special tools, solving the problem of inconvenient removal of residual shells in existing methods and improving the efficiency of nailing operations.
[0004] Although the aforementioned integrated nail gun structure can facilitate the removal of residual casing through the setting of fixing slots and eye holes, it still has the following shortcomings in practical applications: the projectile contains gunpowder, but the projectile has no active safety design. If the ignition hole is accidentally hit during transportation or storage, it is easy to cause the ignition powder to ignite and cause a safety accident. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a split-type nail structure.
[0006] To achieve this objective, the present invention adopts the following technical solution: a split-type nail gun structure, including a nail gun rod and a housing, a nail gun seat assembly is fixedly installed at the bottom of the nail gun rod, the top of the housing is set as an opening, an activation hole is opened at the center of the bottom of the housing, a charge assembly is slidably arranged inside the activation hole, and a connecting assembly is fixedly installed inside the housing, the connecting assembly is located above the charge assembly and cooperates with the nail gun seat assembly and the charge assembly.
[0007] Preferably, the nail gun assembly includes a nail gun base fixedly installed at the bottom end of the nail gun rod, and a first magnetic ring groove is formed at the bottom of the nail gun base, in which a first permanent magnet ring is embedded.
[0008] Preferably, the peripheral wall of the nail base is provided with an annular groove, and an elastic sealing ring is embedded inside the annular groove, which cooperates with the inner wall of the housing.
[0009] Preferably, the connecting assembly includes a connecting seat fixedly installed inside the housing, a second magnetic ring groove is provided on the top of the connecting seat, a second permanent magnet ring is embedded in the second magnetic ring groove, and the second permanent magnet ring cooperates with the first permanent magnet ring, and an opening is provided at the center of the bottom of the connecting seat.
[0010] Preferably, the charging assembly includes a charging cylinder slidably sleeved inside the housing, a connecting post fixedly installed on the top of the charging cylinder, and the top end of the connecting post penetrates the opening at the bottom of the connecting seat and abuts against the bottom of the nail base. Multiple springs are uniformly fixedly connected between the top of the charging cylinder and the bottom of the connecting seat.
[0011] Preferably, the inside of the propellant cartridge is provided with ignition powder and propellant.
[0012] Preferably, a thin-walled groove is formed at the center of the bottom of the charge cartridge, and the position of the thin-walled groove corresponds to the position of the excitation hole.
[0013] The beneficial effects of this utility model are as follows: The nail base at the bottom of the nail gun is inserted into the opening at the top of the housing. The first and second permanent magnet rings automatically attract each other through magnetic attraction, achieving precise alignment and rapid fixation between the nail base and the connecting seat. Simultaneously, when the nail base is pressed down, the elastic sealing ring deforms under pressure, tightly fitting against the inner wall of the housing to form a high-pressure air seal. When the nail base is pressed down, it synchronously pushes the connecting column of the charging assembly downwards. The connecting column drives the charging cartridge to overcome the spring force and slide along the inner wall of the housing towards the bottom. When the nail base is completely attracted to the connecting seat... When the charging cartridge is attached, the bottom of the cartridge precisely abuts against the bottom wall of the housing. At this time, the thin-walled groove at the bottom of the cartridge is precisely aligned with the firing hole at the bottom of the housing, and the cartridge enters the firing state. When not assembled, the spring lifts the cartridge, and the thin-walled groove moves away from the firing hole to avoid accidental firing. Through these settings, the device can not only automatically release the safety the moment it is assembled, but also forcibly separate the charging cartridge from the firing channel when not assembled, avoiding the risk of accidental firing during transportation or storage. It can also achieve quick and accurate alignment of the nail gun rod and the housing through the magnetic attraction structure. Attached Figure Description

[0022] Example 1
[0023] like Figure 1-3 As shown, the present invention proposes a split-type nail structure, including a nail rod 1 and a housing 5. A nail seat assembly 2 is fixedly installed at the bottom of the nail rod 1. The top of the housing 5 is set as an opening. An excitation hole 51 is opened at the center of the bottom of the housing 5. A charge assembly 4 is slidably arranged inside the excitation hole 51. A connecting assembly 3 is fixedly installed inside the housing 5. The connecting assembly 3 is located above the charge assembly 4 and cooperates with the nail seat assembly 2 and the charge assembly 4.
[0024] In this embodiment: the nail gun base assembly 2 includes a nail gun base 21 fixedly installed at the bottom end of the nail gun rod 1. A first magnetic ring groove 22 is formed at the bottom of the nail gun base 21, and a first permanent magnet ring 23 is embedded in the first magnetic ring groove 22. This arrangement allows the first permanent magnet ring 23 to cooperate with the connecting assembly 3, enabling rapid positioning and detachable connection between the nail gun rod 1 and the housing 5, while avoiding rigid collisions and facilitating the assembly and replacement of the split structure. An annular groove 24 is formed on the outer periphery of the nail gun base 21, and an elastic sealing ring 25 is embedded inside the annular groove 24. The elastic sealing ring 25 cooperates with the inner wall of the housing 5. This arrangement allows the nail gun base 21 to be inserted into the housing. At 5 o'clock, the elastic sealing ring 25 is deformed under pressure and fits tightly against the inner wall of the housing 5, forming a high-pressure gas seal to prevent gas from leaking from the gap between the nail rod 1 and the housing 5 during gunpowder combustion, ensuring that the propulsion force is concentrated on the nail base 21 and the nail rod 1; the connecting assembly 3 includes a connecting seat 31 fixedly installed inside the housing 5, the top of the connecting seat 31 is provided with a second magnetic ring groove 32, the second magnetic ring groove 32 is embedded in the second magnetic ring groove 32, and the second permanent magnet ring 33 cooperates with the first permanent magnet ring 23. The bottom center of the connecting seat 31 is provided with an opening, through which the second permanent magnet ring 33 cooperates with the first permanent magnet ring 23 to attract each other, ensuring that the nail base assembly 2 is accurately aligned.
[0025] Example 2
[0026] like Figure 1-3As shown, the present invention proposes a split-type nail structure. Compared with Embodiment 1, this embodiment further includes a charging assembly 4 comprising a charging cylinder 41 slidably sleeved inside the housing 5. A connecting post 42 is fixedly installed on the top of the charging cylinder 41, and the top end of the connecting post 42 penetrates the opening at the bottom of the connecting seat 31 and abuts against the bottom of the nail base 21. Multiple springs 43 are uniformly fixedly connected between the top of the charging cylinder 41 and the bottom of the connecting seat 31. Through this arrangement, the opening at the bottom of the connecting seat 31 provides a through channel for the connecting post 42 of the charging assembly 4. When the base 21 and the connecting seat 31 are magnetically connected together, the base 21 presses the connecting post 42, and the connecting post 42 pushes the charging cylinder 41 to move towards the firing hole 51. When the connecting post 42 is pressed into the opening of the connecting seat 31, the charging cylinder... The cartridge 41 abuts against the bottom wall of the casing 5, enabling automatic disengagement of the safety and readiness for firing upon assembly. In the unassembled state, the cartridge 41 is not fully engaged under the action of the spring, ensuring high safety. The cartridge 41 contains an igniter 45 and a propellant 44. With this arrangement, the igniter 45 is located below the propellant 44. The igniter 45 is ignited by the impact energy of the external firing pin, which then ignites the propellant 44 to produce a stable detonation. A thin-walled groove 46 is formed at the center of the bottom of the cartridge 41, and the position of the thin-walled groove 46 corresponds to the position of the firing hole 51. With this arrangement, the thin-walled groove 46 serves as a structural weakening zone. When the external firing pin impacts this position through the firing hole 51, the thin-walled groove 46 breaks first, allowing the ignition energy to be efficiently transferred to the igniter 45, while controlling the detonation direction and preventing damage to the casing 5.
[0027] Working principle: The nail base 21 at the bottom of the nail gun 1 is inserted into the opening at the top of the housing 5. The first permanent magnet ring 23 and the second permanent magnet ring 33 are automatically attracted by magnetic attraction, achieving precise alignment and rapid fixation between the nail base 21 and the connecting seat 31. At the same time, when the nail base 21 is pressed down, the elastic sealing ring 25 is deformed under pressure and fits tightly against the inner wall of the housing 5, forming a high-pressure air seal. When the nail base 21 is pressed down, it synchronously pushes the connecting column 42 of the charging assembly 4 downward, connecting... The connecting post 42 drives the charging cartridge 41 to overcome the elastic force of the spring 43 and slide down the inner wall of the housing 5. When the nail base 21 is completely attached to the connecting seat 31, the bottom of the charging cartridge 41 just touches the bottom wall of the housing 5. At this time, the thin-walled groove 46 at the bottom of the charging cartridge 41 is precisely aligned with the firing hole 51 at the bottom of the housing. The charging cartridge 41 enters the firing state. When not assembled, the spring 43 lifts the charging cartridge 41, and the thin-walled groove 46 is far away from the firing hole 51 to avoid accidental firing.
[0028] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
