Description

Technical Field

[0001] This utility model belongs to the technical field of nail fastening equipment, specifically relating to a new type of ceiling-mounted projectile. Background Technology

[0002] Ceiling clips are essential for fastening suspended objects in interior decoration and engineering projects due to their fast nailing speed and high work efficiency. Since nail guns in China are basically standardized, the use of ceiling clips has also been largely established. However, the penetration power (fastening force) of ceiling clips has not been definitively determined. Each fastening equipment manufacturer produces according to customer needs, resulting in the lack of a stable technical assessment index for the penetration power of ceiling clips. This instability in penetration power makes the use of ceiling clips unsafe and limits their application, severely restricting the development of ceiling clip products.

[0003] Chinese utility model patent CN216127187U discloses a small plastic ceiling-mounted ammunition body with a charge of 100-130mg, solving the technical problem that there is no small-sized ceiling-mounted ammunition body in the prior art. This utility model includes a cylindrical, hollow ceiling-mounted ammunition cartridge, filled with a firing charge and a nail charge. A 0.035-0.055mm thick explosion-proof paper spacer is provided between the firing charge and the nail charge. The inner diameter of the ceiling-mounted ammunition cartridge is 4.6-5.2mm. This utility model has a simple structure, a scientific and reasonable design, and is easy to use. The inner diameter of the ceiling-mounted ammunition cartridge is set to 4.6-5.2mm. Since the cartridge diameter determines the optimal value of the propellant combustion cross-sectional area, after firing with a small amount of propellant, it can quickly reach the critical combustion surface of optimal combustion. It can effectively improve the instantaneous combustion of the propellant and greatly improve the penetration power of the ceiling-mounted ammunition. At the same time, due to the improved instantaneous combustion of the propellant, the unit amount of propellant can be effectively reduced while ensuring penetration power; the power is increased and the application range is expanded.

[0004] However, its structure can still be improved, which can further enhance the combustion efficiency, projectile performance and adaptability of the suspended projectile. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a novel ceiling-mounted projectile body to solve the problems in the background technology.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A novel ceiling-mounted ammunition body includes a cylindrical and hollow ceiling-mounted ammunition cartridge. The ceiling-mounted ammunition cartridge has a nail charge filling chamber, a firing charge filling chamber, and a firing groove inside. The inner wall of the nail charge filling chamber has micro-protruding ridges, and the lower end of the firing charge filling chamber is directly connected to the nail charge filling chamber.

[0008] Preferably, the nail filling chamber is cylindrical and contains nail explosives.

[0009] Preferably, the propellant filling chamber is frustum-shaped and contains propellant.

[0010] Preferably, the nail filling chamber and the firing charge filling chamber are connected, and the connection between the nail and the firing charge is provided with an explosion-proof paper spacer.

[0011] Preferably, the explosion-proof paper spacer is honeycomb-shaped, and the holes are perpendicular to the plane of the spacer.

[0012] Preferably, the upper end of the ceiling-mounted ammunition cartridge is provided with a firing slot corresponding to the propellant loading chamber.

[0013] Preferably, the firing groove is cylindrical.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] A gradual transition in inner diameter is provided from the tail (firing charge filling chamber) to the head (nailing charge filling chamber) of the ceiling-mounted ammunition cartridge, so that the combustion cross-sectional area gradually increases from the firing end to the propulsion end, matching the change in combustion rate when the firing charge ignites the nail charge, and further improving the combustion continuity;

[0016] The propellant filling chamber is reinforced with micro-protrusions to increase the contact area between the propellant and the inner wall, promote turbulent combustion, shorten the complete combustion time, and enhance instantaneous explosive force. Attached Figure Description

[0025] like Figure 1-2 As shown, this utility model is a novel ceiling-mounted projectile. Specifically, it includes a cylindrical and hollow ceiling-mounted ammunition tube 1. The ceiling-mounted ammunition tube 1 has a nail-filling chamber 2, a firing powder filling chamber 3, and a firing groove 4 inside. The inner wall of the nail-filling chamber 2 has micro-protruding ridges 21. The lower end of the firing powder filling chamber 3 is directly connected to the nail-filling chamber 2.

[0026] In this embodiment, the nail filling chamber 2 is cylindrical and contains nails.

[0027] In this embodiment, the propellant filling chamber 3 is frustum-shaped and contains propellant.

[0028] In this embodiment, the nail filling chamber 2 and the firing charge filling chamber 3 are connected, and an explosion-proof paper spacer 5 is provided at the connection between the nail and the firing charge inside.

[0029] In this embodiment, the explosion-proof paper spacer 5 is honeycomb-shaped, and the holes are perpendicular to the spacer plane.

[0030] In this embodiment, the upper end of the ceiling-mounted ammunition cartridge 1 is provided with a firing groove 4 corresponding to the firing charge filling chamber 3.

[0031] In this embodiment, the firing groove 4 is cylindrical.

[0032] In practical use, the firing device strikes the firing groove 4 at the rear of the ceiling-mounted ammunition cartridge 1. The impact force is transmitted through the groove to the propellant filling chamber 3. The propellant is ignited by the impact, generating a high-temperature flame and gas. The flame generated by the burning propellant is sprayed through the connection between the bottom surface of the frustum-shaped chamber and the nail filling chamber 2 onto the side of the explosion-proof paper septum 5 near the propellant. The honeycomb structure of the septum increases the flame contact area. The flame is quickly conducted to the surface of the nail through the pores on the septum, igniting the nail. After the nail is ignited, it burns rapidly, generating a large amount of high-temperature and high-pressure gas. The high-pressure gas pushes the nail towards the front end of the cartridge, penetrating the base to complete the fixation.

[0033] A gradual transition in inner diameter is designed from the tail (firing charge filling chamber) to the head (nailing charge filling chamber) of the ceiling-mounted ammunition cartridge, so that the combustion cross-sectional area gradually increases from the firing end to the propulsion end, matching the change in combustion rate when the firing charge ignites the nail charge, and further improving combustion continuity; micro-protrusions are added to the inner wall of the nail charge filling chamber to increase the contact area between the propellant and the inner wall, promote turbulent combustion, shorten the complete combustion time, and enhance instantaneous explosive force.

[0034] The above are merely embodiments of this utility model. The circuits, electronic components, and modules involved are all prior art, fully achievable by those skilled in the art, and require no further explanation.

Those skilled in the art are aware of all common technical knowledge in the field to which this utility model pertains prior to the application date or priority date, are able to access all existing technologies in that field, and possess the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, under the guidance of this application, improve and implement this solution in conjunction with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
