Description
Technical Field
The utility model relates to a pneumatic nail rifle, concretely relates to piston assembly of pneumatic 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 a piston body impacts a nail to work. The piston assembly comprises a piston body, a firing pin connected to the piston body and a sealing ring arranged on the piston, and the structural design of the piston assembly of the existing pneumatic nail gun is unreasonable. The connection between the firing pin and the piston is not compact, and the firing pin and the piston are easy to loosen, so that the piston assembly of the pneumatic nail gun also has the defects of being not compact in structure, unreliable in performance and inconvenient to assemble.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, compact structure, assemble convenient, long service life's piston assembly of pneumatic nail rifle.
For realizing above-mentioned mesh, the utility model discloses a piston assembly of pneumatic nail rifle, including cylinder body, setting piston in the cylinder body, the firing pin of setting on the piston, the one end of firing pin be provided with the striking portion of extension outside the cylinder body, the other end of firing pin on have joint portion, the piston on be provided with joint portion matched with joint hole, joint portion block downthehole at the joint, and constitute the joint cooperation of piston and firing pin, the firing pin on correspond one side department setting and spacing portion of joint portion, be provided with the annular knurl on the periphery wall of this spacing portion, the piston on be provided with spacing portion matched with spacing groove, spacing groove and joint hole be linked together, and spacing portion block is at spacing inslot, and constitute the spacing cooperation of firing pin and piston.
The beneficial effect of above-mentioned structure is: be provided with joint portion, spacing portion respectively on the firing pin, be provided with the annular knurl with piston looks block on the spacing portion to can guarantee that the connection of firing pin and piston is compacter, firing pin and piston are difficult not hard up, drop, are favorable to improving the operational reliability of this piston assembly. Thereby the piston assembly of the pneumatic nail gun has the advantages of simple structure, compact structure and convenient and fast assembly.
In particular, the piston is provided with a sealing ring matched with the cylinder body, and the sealing matching of the piston and the cylinder body is formed. The sealing ring can play a role in sealing, can ensure the sealing performance between the cylinder body and the piston, and is favorable for improving the working reliability of the piston assembly.
In particular, a buffer cushion matched with the piston is arranged in one end of the cylinder body. The buffer pad can play a role in buffering the piston, and is favorable for prolonging the service life of the piston.
Particularly, the cylinder body in the cylinder body is provided with a clamping groove corresponding to the buffering cushion, the buffering cushion is provided with a clamping convex block matched with the clamping groove, and the clamping convex block is clamped in the clamping groove and forms clamping matching of the cylinder body and the buffering cushion. The blotter adopts the joint cooperation mode with the cylinder body to be connected to the assembly of the cylinder body of being convenient for and blotter, assembly efficiency is higher.
