Abstract

The utility model discloses a pneumatic tool inner main piston reinforcing structure and belongs to a pneumatic tool piston. The pneumatic tool inner main piston reinforcing structure comprises a nail-beating rod, a main piston, a flat gasket, an elastic gasket, a locking nut and a washer. The nail-beating rod is provided with a step, the washer and the main piston are arranged between one end of the nail-beating rod and the step, and the end of the main piston is fixed to the nail-beating rod through the flat gasket, the elastic gasket and the locking nut. The thread portion of the main piston is replaced by a through hole, the flat gasket and the washer are arranged at the two ends, connected with the nail-beating rod, of the main piston and serve as main force bearing parts, the upper portion of the main piston is tightened through the locking nut, the step on the nail-beating rod and the washer serve as lower stopping points of the lower end of the main piston, and when the beating force of a pneumatic tool is large, the thread portion of the aluminum main piston is not prone to damage. The pneumatic tool inner main piston reinforcing structure has the advantages that when large force is borne by the nail-beating rod, the force is shared by the flat gasket and the washer which are arranged at the two ends of the main piston to serve as a tightened locking nut and elastic gasket combination, and therefore beating bearing performance and anti-loosening performance of the pneumatic tool inner main piston reinforcing structure are greatly improved.

Description

Main piston reinforced structure in a kind of pneumatic tool
Technical field
The utility model relates to main piston reinforced structure in a kind of pneumatic tool piston, particularly a kind of pneumatic tool.
Background technique
At present, well-known, in pneumatic tool, there is a piston structure, described piston structure comprises: nail hitting bar and main piston; There is screw thread one end of nail hitting bar, and there is tapped hole at the center of main piston, and the screw thread of nail hitting bar is directly screwed in the tapped hole of main piston.Nail hitting bar is connected with main piston by screw thread, and its shortcoming is: in the time that pneumatic tool is worked, force de frappe is larger, and the helical thread portion of the main piston of the screw thread of nail hitting bar and aluminium matter is very easy to damage, and greatly reduces air tool working life.
Model utility content
The purpose of this utility model is that main piston reinforced structure in a kind of pneumatic tool will be provided, and solves when pneumatic tool force de frappe is large, and the piston structure helical thread portion of aluminium matter holds flimsy problem.
The purpose of this utility model is achieved in that main piston reinforcement structure comprises: nail hitting bar, main piston, plain cushion, bullet pad, locking nut and packing ring; On nail hitting bar, there is step, have main piston in one end of nail hitting bar to step position, be fixed on nail hitting bar by plain cushion, bullet pad and locking nut and packing ring in the end of main piston.
Beneficial effect: owing to having adopted such scheme, helical thread portion in main piston is cancelled, be processed into through hole, there are plain cushion and packing ring in the two ends that main piston is connected with nail hitting bar as bearing strength major component, it is fastening that top has locking nut to carry out, and there are step on nail hitting bar and packing ring in lower end as lower dead center, has solved when pneumatic tool force de frappe is large, the helical thread portion of the main piston of aluminium matter holds flimsy problem, has reached the purpose of this utility model.
Advantage: when nail hitting bar bears larger strength, its strength disperses to bear by plain cushion and the packing ring at main piston two ends, and as fastening locking nut and the combination of bullet pad, has greatly strengthened this structure and born force de frappe and locking.
Brief description of the drawings
Fig. 1 is structural drawing of the present utility model.
In figure, 1, nail hitting bar; 2, main piston; 3, plain cushion; 4, bullet pad; 5, locking nut; 6, packing ring.
Embodiment
Embodiment 1: this main piston is strengthened structure and comprised: nail hitting bar 1, main piston 2, plain cushion 3, bullet pad 4, locking nut 5 and packing ring 6; On nail hitting bar 1, there is step, have packing ring 6 and main piston 2 to step position in one end of nail hitting bar 1, be fixed on nail hitting bar 1 by plain cushion 3, bullet pad 4 and locking nut 5 at the other end of main piston 2.

Claims (1)

1. a main piston reinforced structure in pneumatic tool, is characterized in that: this main piston is strengthened structure and comprised: nail hitting bar, main piston, plain cushion, bullet pad, locking nut and packing ring; On nail hitting bar, there is step, have packing ring and main piston in one end of nail hitting bar to step position, be fixed on nail hitting bar by plain cushion, bullet pad and locking nut at the other end of main piston.
