Technical Field

[0001] This utility model belongs to the field of nail fastening equipment, specifically, it relates to a high-power special nail gun cartridge. Background Technology

[0002] Currently, nail gun cartridges commonly used both domestically and internationally are classified into six levels based on their power. This classification system aims to adapt to the requirements of penetration, fastening force, and material strength in different construction scenarios. However, even in the highest power level, such as the S3-level nail gun cartridge known as the "black bullet," its limited power may not fully meet construction requirements in certain special construction environments—such as anchoring operations in extremely hard concrete structures, thickened steel plates, or composite building materials. These situations may lead to insufficient penetration depth, insecure fixation, or repetitive work, thus affecting project efficiency and structural safety. Therefore, a high-power nail gun cartridge is urgently needed. Utility Model Content

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0016] It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 , Figure 2 As shown, this utility model provides a high-power special nail gun cartridge, including a cartridge case 1. The cartridge case 1 contains an ignition nail gun cartridge 2 and a nitrocellulose propellant 3. The ignition nail gun cartridge 2 and the nitrocellulose propellant 3 are arranged in contact or at intervals within the cartridge case 1, but they cannot be separated. This ensures that the ignition nail gun cartridge 2 ignites the nitrocellulose propellant 3 upon explosion, causing the nitrocellulose propellant 3 to explode. Simultaneously, when the ignition nail gun cartridge 2 and the nitrocellulose propellant 3 are arranged, the nitrocellulose propellant 3 is positioned in front of the ignition nail gun cartridge 2. This ensures that when the nail gun is used, the firing pin first fires the ignition nail gun cartridge 2, and then the explosion of the ignition nail gun cartridge 2 ignites the nitrocellulose propellant 3, causing both the ignition nail gun cartridge 2 and the nitrocellulose propellant 3 to explode, thus greatly increasing the power of the nail gun cartridge.

[0018] In this invention, the ignition nail cartridge 2 can be an S1 nail cartridge; of course, depending on the needs, the ignition nail cartridge 2 can also be an S2 nail cartridge, an S3 nail cartridge, an S4 nail cartridge, etc. That is, the selection of the ignition nail cartridge 2 can be made according to the actual situation.

[0019] In this invention, to facilitate the placement of the ignition nail cartridge 2 and the nitrocellulose propellant 3 within the cartridge case 1, the cartridge case 1 also includes a propellant magazine 13 and a magazine 11. The central axis of the propellant magazine 13, the central axis of the magazine 11, and the central axis of the cartridge case 1 are collinear, and the magazine 11 and the propellant magazine 13 are connected. The shape of the magazine 11 is adapted to the shape of the ignition nail cartridge 2, and the ignition nail cartridge 2 is interference-fitted with the magazine 11, ensuring that the ignition nail cartridge 2 remains stable after being inserted into the magazine 11. To facilitate the firing of the ignition nail cartridge 2 within the magazine 11, the end of the magazine 11 furthest from the propellant magazine 13 is open. When the ignition nail cartridge 2 is installed in the magazine 11, the end face of the ignition nail cartridge 2 is flush with the end face of the cartridge case 1. To prevent the nitrocellulose propellant 3 from falling out after being loaded into the propellant magazine 13, the end of the propellant magazine 13 away from the magazine 11 is closed; however, in order to ensure that the nitrocellulose propellant 3 can explode smoothly after being ignited and apply the explosive force to the nail, the part of the cartridge case 1 used to seal the nitrocellulose propellant 3 can be made thinner.

[0020] In order to ensure the sealing of the nitrocellulose propellant 3 while facilitating the production of the cartridge case 1, the side of the cartridge case 1 away from the ammunition magazine 11 can be set open during production. After the nitrocellulose propellant 3 is installed in the cartridge case 13, the side of the cartridge case 13 away from the ammunition magazine 11 is sealed with sealing glue 4, thereby sealing the nitrocellulose propellant 3 inside the cartridge case 13.

[0021] That is, in this utility model, without affecting the loading of the nitrocellulose propellant 3 into the propellant magazine 13, the cartridge case 1 can be designed such that the side of the propellant magazine 13 away from the magazine 11 does not penetrate the end face of the cartridge case 1, so that the nitrocellulose propellant 3 will not fall out of the cartridge case 1 after being loaded into the propellant magazine 13. In this case, the end face of the front end of the cartridge case 1 can be a flat end face or a concave end face. In this utility model, without affecting the loading of the nitrocellulose propellant 3 into the propellant magazine 13, the side of the propellant magazine 13 away from the magazine 11 can also be directly made to penetrate the end face of the cartridge case 1. After the nitrocellulose propellant 3 is loaded into the propellant magazine 13, the side of the propellant magazine 13 away from the magazine 11 is sealed with sealing glue 4. In this case, when sealing the propellant magazine 13, the sealing glue 4 can be flush with the end face of the front end of the cartridge case 1, or the sealing glue 4 is lower than the end face of the front end of the cartridge case 1.

[0022] In this invention, to ensure that the igniting nail gun 2 can ignite the nitrocellulose propellant 3 upon explosion, a ignition hole 12 for connecting the propellant magazine 13 and the ammunition magazine 11 can be provided inside the cartridge case 1. The central axis of the ignition hole 12 is on the same straight line as the central axis of the cartridge case 1, and the diameter of the ignition hole 12 is smaller than the diameter of the propellant magazine 13 and the minimum diameter of the ammunition magazine 11, so as to prevent the nitrocellulose propellant 3 or the igniting nail gun 2 in the propellant magazine 13 from entering the ignition hole 12. At the same time, by making the diameter of the ignition hole 12 smaller than the diameter of the propellant magazine 13 and the minimum diameter of the ammunition magazine 11, both the propellant magazine 13 and the ammunition magazine 11 have a limiting end face, so that the nitrocellulose propellant 3 and the igniting nail gun 2 are more stable after installation. In this invention, when the shape of the ignition nail cartridge 2 is not cylindrical, the diameter of the ignition hole 12 can be greater than or equal to the minimum diameter of the ignition nail cartridge 2, but the diameter of the ignition hole 12 must be less than the maximum diameter of the ignition nail cartridge 2. At the same time, while ensuring that the energy of the ignition nail cartridge 2 can pass through the ignition hole 12 to ignite the nitrocellulose propellant 3 when it explodes, the central axis of the ignition hole 12 can also be deviated from the central axis of the cartridge case 1.

[0023] In this invention, in order to facilitate the loading of nitrocellulose propellant 3 into the propellant chamber 13, the nitrocellulose propellant 3 can be processed into blocks or flakes in the early stage. During the production of nail gun bullets, the block or flake nitrocellulose propellant 3 can be directly loaded into the propellant chamber 13 and then sealed with sealing glue 4. This not only makes the production of nail gun bullets faster and more convenient, but also keeps the amount of nitrocellulose propellant 3 loaded into the propellant chamber 13 fixed.

[0024] In this invention, the end of the cartridge case 1 where the igniting nail gun cartridge 2 is installed is the rear end of the cartridge case 1, and the end of the cartridge case 1 where the nitrocellulose propellant 3 is installed is the front end of the cartridge case 1. The rear end of the cartridge case 1 also has an ejection disc 14, which is a raised annular shape on the outer wall of the cartridge case 1. The thickness of the ejection disc 14 can be selected according to the actual situation. By setting the ejection disc 14, this invention allows for easy ejection from the gun barrel after detonation.

[0025] In this utility model, such as Figure 3 As shown, an ejection groove 14' can also be directly opened at the rear end of the cartridge case 1, and the distance between the ejection groove 14' and the rear end face of the cartridge case 1 can be selected according to the actual situation. This design can replace the structure of setting the ejection disc 14 at the rear end of the cartridge case 1, and can also make it easy for the present invention to be ejected from the gun barrel of the nail gun after the explosion.

[0026] In the design of the cartridge case 1 of this utility model, the outer diameter of the cartridge case 1 gradually increases from front to back, making the outer wall of the cartridge case 1 conical, which facilitates the installation of the nail gun cartridge into the fastening equipment.

[0027] In the production of this utility model, the cartridge case 1 is first processed and shaped by injection molding, the ignited nail gun 2 is loaded into the loading chamber 11, then the nitrocellulose propellant 3, which is processed into block or sheet shape, is loaded into the propellant chamber 13, and finally the opening of the propellant chamber 13 is sealed with sealing glue 4, thus sealing the nitrocellulose propellant 3 inside the propellant chamber 13, thereby completing the processing of the high-power special nail gun 11.

[0028] During construction, high-power special nail gun cartridges are loaded into a special nail gun. The firing pin of the nail gun ignites the nail gun cartridge 2, causing it to explode. The heat generated by the explosion of the nail gun cartridge 2 ignites the nitrocellulose propellant 3 through the ignition hole 12, thereby generating greater power and pushing the piston rod of the nail gun to complete the construction requirements under the specified energy. The cartridge case 1 of the high-power special nail gun cartridge is ejected from the chamber of the nail gun.

[0029] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
