Abstract
The utility model discloses a new air cylinder inside a chain saw and the new air cylinder inside a chain saw comprises an air cylinder body, cooling fins, an air inlet, an air outlet, a placing chamber, a tapping hole, a gas running groove, and a strip-type groove, wherein the air cylinder is provided with a plurality of integrated molding cooling fins, the air outlet and the air inlet, the placing chamber is arranged inside the air cylinder, and the tapping hole which is communicated with outside is formed in the upper end of the placing chamber. The gas running groove and the strip-type groove are formed in the inner wall of the placing chamber; a through hole is formed in the strip-type groove and is communicated with an end face of the air inlet. The cooling fins are provided with a plurality of circular holes on a same shaft and two locating columns are arranged on end surface of the air inlet. The air inlet and the air outlet are not in a same line. The new air cylinder inside a chain saw has the advantages that cooling fins enable the air cylinder to be cooled quickly, the connection is very stable, the operation is very smooth, the intensity is very high, stiffness is very strong, effective lubrication enables operation to be very smooth, vibration noise is small, and service life is long.
Description
Technical field
The utility model relates to a kind of air cylinder structure, particularly the cylinder block in a kind of novel chain saw.
Background technique
Cylinder block is the main body of motor, and it is connected each cylinder and crankcase, is the support framework that piston, bent axle and other part and accessories are installed.The operating conditions of cylinder block is very severe, it will bear the sharply variation of pressure and temperature in combustion process and the strong friction of piston movement, so the characteristic needing has, intensity is high, rigidity is high, it is little to be out of shape, in movement process, moving parts position is normal coordinates closely, vibrating noise is little, wear-resisting, can bear various load, and heat radiation must be fast, but all can there is some problems in present cylinder block.
Model utility content
For addressing the above problem, this practical purpose be to provide a kind of quick heat radiating, intensity high, lightweight, coordinate closely, the cylinder block in noise is little, physical life is permanent novel chain saw.
For achieving the above object, this practical technological scheme:
Cylinder block in a kind of novel chain saw, comprise cylinder body, radiating fin, air outlet, suction port, placed cavity, piston mouth, deflation groove, bar-shaped trough, described cylinder body is provided with some radiating fin, air outlet and the suction port of integral molding, in cylinder body, be provided with a placed cavity, placed cavity upper end has one and is communicated to outside piston mouth, on placed cavity inwall, have deflation groove and bar-shaped trough, on bar-shaped trough, have a through hole that is communicated to suction port end.
As preferably, described radiating fin is provided with some circular holes on same axle.
As preferably, described suction port end face is provided with two locating columns.
As preferably, described air outlet and suction port be not on same straight line.
Beneficial conditions of the present utility model is: some radiating fin make heat radiation fast, are connected firmly stable, moves smooth and easy, high strength, high rigidity, is out of shape littlely, effectively lubricatedly makes to move smooth and easy, and vibrating noise is little, long perfomance life.
