Description

Novel suspended ceiling bomb body Technical Field The utility model belongs to the technical field of nail-shooting fastening equipment, and particularly relates to a novel suspended ceiling bomb body. Background The suspended ceiling bullet is fast because of the nailing, work efficiency is high, be the essential fastening equipment who hangs the object of interior decoration and engineering class, because domestic nail shooter has basic design, the mode of suspended ceiling bullet fastening equipment also has basic application range, but the penetration force (fastening force) of suspended ceiling bullet fastening equipment has not been finally confirmed all the time, each enterprise that produces fastening equipment all produces according to customer's demand, finally do not form stable technical assessment index to fastening equipment (suspended ceiling bullet) penetration force, because the penetration force is unstable, suspended ceiling bullet's use is unsafe, application range is narrow and small, serious restriction suspended ceiling bullet product's development. The Chinese patent with publication number of CN216127187U discloses a plastic small-sized suspended ceiling elastomer with the loading capacity of 100-130mg, which solves the technical problem that the prior art does not have a small-sized suspended ceiling elastomer. The utility model comprises a cylindrical suspended ceiling cartridge with hollow inside, wherein the suspended ceiling cartridge is filled with a firing medicine and a nailing medicine, an explosion-proof paper spacer with the thickness of 0.035-0.055mm is arranged between the firing medicine and the nailing medicine, and the inner diameter of the suspended ceiling cartridge is 4.6-5.2mm. The utility model has simple structure, scientific and reasonable design and convenient use, the inner diameter of the suspended ceiling cartridge is set to be 4.6-5.2mm, the diameter of the cartridge determines the optimal value of the combustion cross section of the propellant powder, after firing under the condition of small-dosage charge, the critical combustion surface of the optimal combustion can be quickly reached, the instant combustion of the propellant powder can be effectively improved, the penetrating power of the suspended ceiling bomb is greatly improved, meanwhile, the instant combustion of the propellant powder is improved, the loading quantity of the propellant powder per unit can be effectively reduced under the condition of ensuring the penetrating power, the power is increased, and the application range is enlarged. But can still improve its structure, can make the furred ceiling bullet body obtain further promotion in aspects such as combustion efficiency, body performance and adaptability. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides a novel suspended ceiling elastomer, which is used for solving the problems in the prior art. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a novel furred ceiling bullet body, is including being cylindrical and interior hollow furred ceiling cartridge, the inside nail medicine that is equipped with of furred ceiling cartridge is filled cavity, is equipped with micro-bead to the percussion medicine and fills cavity and percussion groove, the inner wall that the cavity was filled to the nail medicine, the percussion medicine is filled the lower extreme of cavity and is directly filled the cavity with the nail medicine and be connected. Preferably, the spike filling chamber is cylindrical and internally filled with the spike.
