Embodiment 1
[0030] The nail gun of the present embodiment is as figure 1 As shown, it is mainly composed of: 1. Nail feeding mechanism; 2. Cylinder assembly; 3. Combustion chamber assembly; 4. Shell handle assembly; 5. Battery pack, switch control assembly; several parts. When the mixture of air and fuel in the combustion chamber is ignited to generate power, the piston is pushed, and the striker drives the nail into the workpiece and the hard substrate to realize the connection between the workpiece and the hard substrate. In order to fully burn the fuel and generate higher power, there is a ventilation fan 32 in the combustion chamber, whose main function is to discharge the burned carbon dioxide gas, suck new air into the combustion chamber, and mix it with the fuel. The motor 34 drives the fan 32, and the motor 34 is suspended on the combustion chamber cover 35. Since the air and fuel mixture is ignited and exploded, a reverse impact force is generated on the fan, and the impact force...

The invention relates to a suspended sealing device of a nail gun electric motor, and belongs to the technical field of gas power tools. The device comprises a combustion chamber cover for sealing one end of a combustion chamber; a cylindrical die cavity for placing the electric motor is arranged in the middle of the combustion chamber cover; the electric motor with a sheathed outer cover is placed inside the die cavity; both ends of the electric motor are respectively limited with the combustion chamber cover axially after passing through the cushion of the electric motor; the outer circle of the cushion of the electric motor is provided with a convex ring tightly attached to the inner wall of the cylindrical die cavity; and a groove is formed in the inner hole of the cushion of the electric motor. After assembling, under the effects of a cushion rubber and a bushing at both ends of the electric motor, multiple sealing can be formed in the combustion chamber, so that good static sealing can be realized. When the electric motor is forced by the vibration effect of axial impact, the cushion rubber of the electric motor with the groove in the inner hole can generate high axial deformation and can efficiently absorb vibration energy, and the convex ring on the radial outer ring further generates extension trend, so that reliable sealing effect also can be ensured under dynamic condition.
Description
technical field [0001] The invention relates to a nail gun, in particular to a nail gun motor suspension sealing device, which belongs to the technical field of gas power tools. Background technique [0002] The gas nail gun ignites the mixture of air and fuel to generate power to drive the nail into the hard substrate of the workpiece, realize the connection between the workpiece and the hard substrate, and greatly improve work efficiency, mobility and convenience. [0003] The search found that the Chinese patent application number 01141528.2 discloses a combustion power tool suspension mechanism for an iron-core fan motor. at least one of the accelerations causes the motor to vibrate relative to the tool, the suspension mechanism includes a suspension configured to provide incremental shock absorption to the motor as axial accelerations are generated. In addition, Chinese patent application No. 03156777.0 discloses a fan motor suspension mount for combustion actuation to...
