Description
Technical Field
The utility model relates to a pneumatic nail rifle, concretely relates to cylinder assembly of nail rifle.
Background
The pneumatic nail gun is also called as a pneumatic nail gun, and the pneumatic nail gun drives a firing pin in a nail gun cylinder to perform hammering movement by using air pressure generated by an air pump (an air compressor) so as to drive the row nails in a row nail clamp into an object or eject the row nails. The pneumatic nail gun uses compressed air as power to push a piston assembly in the nail gun, so that a firing pin on the piston impacts a nail to work. The piston assembly comprises a piston, a firing pin connected to the piston and a sealing ring arranged on the piston, and the structural design of the cylinder of the existing pneumatic nail gun is unreasonable. The structural design of this cylinder is complicated, and the cylinder adopts the aluminum alloy material to process and makes, and manufacturing procedure is more complicated, and the cost is higher.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a cylinder assembly of nail rifle of simple structure, long service life, stable performance, with low costs.
In order to achieve the purpose, the utility model discloses a cylinder assembly of nail rifle, including the cylinder body, set up the piston in the cylinder body, with piston linkage complex firing pin, the one end of cylinder body be provided with the cylinder cap, be formed with cylinder cavity between this cylinder cap and the cylinder body, the piston slide and set up at cylinder cavity, the cylinder body be provided with a plurality of gas pockets that are used for intercommunication cylinder cavity and external, the periphery wall of cylinder body on correspond each gas pocket department and be provided with the recess, the recess in be provided with the sealing rubber circle of contradicting on each gas pocket, and be provided with annular boss on the periphery wall of cylinder body, be provided with the cell body on this annular boss, be provided with in this cell body with the sealed complex rubber circle of nail rifle shell.
The beneficial effect of above-mentioned structure is: the cylinder body of the cylinder assembly is formed by injection molding of self-lubricating engineering plastics, subsequent secondary processing is not needed, the processing procedure is simpler, the lubricating effect of the cylinder body is good, lubricating oil does not need to be added frequently when the cylinder body is in contact with a piston, the maintenance cost is reduced, a rubber ring in sealing fit with a nail gun shell is arranged on the cylinder body, the sealing performance of the cylinder assembly is improved, and therefore the cylinder assembly of the nail gun has the advantages of being simple in structure, long in service life, stable in performance and low in cost.
Particularly, a groove is formed in the peripheral wall of the piston, a sealing ring is arranged in the groove, a self-lubricating piston ring wrapped on the sealing ring is arranged in the groove, the upper end face of the self-lubricating piston ring extends out of the peripheral wall of the piston, one end of the firing pin is connected with the piston, and the other end of the firing pin is provided with a firing part extending outside the cylinder body. Be provided with sealing washer, self-lubricating piston ring in the recess of piston, the sealing performance of piston is good, and self-lubricating piston ring and cylinder contact, and self-lubricating piston ring adopts polytetrafluoroethylene material to make, and self-lubricating piston ring's lubricated effectual, intensity is high, wear resistance is good, does not need to add lubricating oil, is favorable to having saved the maintenance cost.
