Example Embodiment

[0027] Refer below Figure 2~Figure 8 The specific embodiment of the linear compressor of the present invention is described in detail.

[0028] figure 2 and image 3 It is a schematic structural diagram of the linear compressor in the present invention, which is the first embodiment. like figure 2 and image 3 As shown, the cylinder 7 is a long-axis cylinder, that is, the axial length of the cylinder block of the cylinder 7 is greater than the axial length of the inner stator 3 . A flange 71 extending radially outward is formed on the outer circumferential surface of the cylinder 7 at its right end, and the flange 5 is arranged on the outer circumferential surface of the flange 71 . The cylinder body of the cylinder 7 protrudes into the inner stator 3 , and the outer circumferential surface of the cylinder body is in contact with the inner surface of the inner stator 3 . The right end face of the inner stator 3 abuts on the left face of the flange 5 and the flange 71 ...

Abstract

The invention provides a linear compressor comprising an inner stator and an outer stator which are cylindrical. The outer stator is disposed on the outer side of the inner stator, a flange is arranged at one end of the inner stator, an air cylinder is fixed on the flange, a cylinder body of the air cylinder extends into the inner stator, a piston is arranged in the air cylinder, a stator pressing plate is arranged at the other end of the inner stator, a spring retaining plate is arranged oppositely to the stator pressing plate, a rotor frame connected with the piston is arranged between the inner stator and the outer stator and positioned between the spring retaining plate and the stator pressing plate, the linear compressor further comprises a fixing mechanism, and the fixing mechanism penetrates the rotor frame and the inner stator respectively to fix the spring retaining plate, the stator pressing plate and the flange together. Consequently, needs of the whole linear compressor can be guaranteed, and firmness in fixing of parts which are coaxial can can be guaranteed, so that coaxiality of the linear compressor is guaranteed, and improving of reliability of the linear compressor is facilitated.

Description

technical field [0001] The present invention relates to a linear compressor. Background technique [0002] Such as figure 1 As shown, the linear compressor generally has a cylindrical casing 1, and lubricating oil is contained at the bottom of the casing 1. A cylindrical casing 12 is accommodated in the casing 1 , and an outer stator 2 , an inner stator 3 , a cylinder 7 and a piston 6 are accommodated in the casing 12 . Wherein, the outer stator 2 and the inner stator 3 are both cylindrical, and the outer stator 2 is arranged close to the inner surface of the housing 12, and the inner stator 3 is placed in the outer stator 2, and there is a gap between the two. A magnet as a mover and a mover frame 8 for fixing the magnet are arranged in the interval. The cylinder 7 is cylindrical as a whole, and a flange 71 extending radially outward is formed on the outer peripheral surface of the cylinder 7 at the right end of the cylinder, and a flange 5 is arranged on the outer perip...
