The compressor is an important refrigerant compression device as a core component of the refrigeration device. The compressor sucks in the low-pressure refrigerant gas returned from the evaporator, compresses the low-pressure refrigerant gas to form a high-temperature high-pressure refrigerant gas, and discharges the high-temperature high-pressure refrigerant gas. The compressor consists of a pump body, a motor, a shell, a liquid separator and other parts, and the process of changing the refrigerant gas from low pressure to high pressure of the compressor is carried out in the pump body of the compressor. As shown in fig. 1, the pump body mainly comprises a crankshaft 10', a compressor cylinder 40', an upper bearing 20', a lower bearing 30', a slide 50', and an elastic member 51'. Wherein, the cylinder body 41 'of the compressor cylinder 40' is radially provided with a spring hole 412 'and a slide slot 411', and the slide 50 'and the elastic member 51' are respectively assembled in the slide slot 411 'and the spring hole 412'. At the end of the spring hole 412' is provided a blocking member 414' for preventing the slide elastic member 51'. One end of the elastic member 51' is connected to the sliding piece 50', and the other end is connected to the blocking member 414'. The slide 50' can be radially reciprocated in the slide slot 411' by the elastic member 51'.

With the trend of increasingly miniaturizing compressors, the diameter of the compressor housing is gradually decreasing. In order to ensure volumetric efficiency of the compressor pump body, the eccentric amount of the eccentric portion of the crankshaft 10' cannot be greatly reduced. In order to secure the strength of the compressor cylinder 40', the thickness of the wall of the slot bottom hole 413' cannot be reduced due to the spring hole 412 'and the slot bottom hole 413'. In the related art, the length of the slide slot 411 'is shortened on the basis of not changing the thickness of the wall of the slot bottom hole 413', so as to ensure the strength of the compressor cylinder, thereby realizing the miniaturization design of the compressor. This results in an increase in the slide extraction rate 50 'and a deterioration in the follow-up performance of the slide 50', thereby affecting the compressor efficiency.

The embodiment of the disclosure provides a gleitbretter subassembly, compressor cylinder 40 and pump body subassembly, through canceling spring hole and groove bottom hole, sets up limit structure 52 to can guarantee the length in gleitbretter groove 411 on the basis of guaranteeing compressor cylinder 40 intensity, thereby reduce the percentage of extension of gleitbretter 50, improve the following nature of gleitbretter 50, and then improve the compressor efficiency.

As shown in connection with fig. 1-7, embodiments of the present disclosure provide a slider assembly including a spacing structure 52, an elastic member 51, and a slider 50. The spacing structure 52 includes a base plate 521 and a first plate 522 connected to a first end of the base plate 521. The first end of the elastic member 51 is connected to the first plate 522. The slide 50 is connected to a second end of the elastic member 51. The bottom surface of the sliding vane 50 and the upper surface of the bottom plate 521 are at the same level, and the sliding vane 50 can slide along the radial direction on the upper surface of the bottom plate 521 under the action of the elastic member 51.

The sliding vane assembly provided in the embodiment of the present disclosure includes a limiting structure 52, an elastic member 51, and a sliding vane 50. The limiting structure 52 includes a base plate 521 and a first plate 522 connected to a first end of the base plate 521, so that the limiting structure 52 formed by the base plate 521 and the first plate 522 can be used to mount the elastic member 51, thereby defining the sliding direction of the sliding vane 50. The elastic member 51 has a first end connected to the first plate 522 and a second end connected to the sliding vane 50 such that the sliding vane 50 can reciprocate in a radial direction of the bottom plate 521 under the action of the elastic member 51. Further, the bottom surface of the sliding vane 50 is disposed at the same level as the upper surface of the bottom plate 521, so that the sliding vane 50 can slide radially on the upper surface of the bottom plate 521 more conveniently under the action of the elastic member 51, so as to prevent the sliding vane 50 from being jammed during the sliding process, thereby affecting the normal movement of the sliding vane 50. The sliding vane assembly is disposed in the sliding vane slot 411, and the sliding vane 50 can reciprocate radially along the sliding vane slot 411 under the action of the elastic member 51. Through setting up limit structure 52, can guarantee the length of gleitbretter groove 411 on the basis of guaranteeing compressor cylinder 40 intensity to reduce the percentage of extension of gleitbretter 50, improve the following nature of gleitbretter 50, and then improve the compressor efficiency.

In some alternative embodiments, the elastic member 51 may be a spring. The first end of the spring is connected to the first plate 522 and the second end is connected to the slider 50. The slide 50 can thus reciprocate in the radial direction of the bottom plate 521 under the action of the spring.

In some alternative embodiments, the first end of the bottom plate 521 of the limiting structure 52 is connected perpendicular to the first end of the first plate 522. Therefore, the limit structure 52 can be more conveniently assembled in the slide sheet slot 411 of the compressor cylinder 40, and meanwhile, the bottom plate 521, the first plate 522 and the inner wall of the slide sheet slot 411 are more attached, so that the strength of the compressor cylinder 40 is better.

In some alternative embodiments, the first plate 522 has a limiting protrusion 5221 on an inner wall thereof, and the first end of the elastic member 51 is connected to the limiting protrusion 5221.

As shown in fig. 3 and 4, the inner wall surface of the first plate 522 of the limiting structure 52 is provided with a limiting protrusion 5221. The first end of the elastic member 51 is connected to the limiting protrusion 5221, so that the elastic member 51 can be more conveniently fixed to the inner wall surface of the first plate 522. Meanwhile, since the elastic member 51 is disposed laterally, the elastic member 51 tends to slide downward due to its own weight. The limiting projection 5221 has a supporting effect on the elastic member 51 to prevent the elastic member 51 from sliding down, thereby making the fixation of the elastic member 51 and the inner wall surface of the first plate 522 more firm.

Further, the slider 50 is reciprocated radially along the slider slot 411 by the elastic member 51. During the radial sliding of the sliding vane 50, the pressing force of the sliding vane 50 against the elastic member 51 is applied to the compressor cylinder 40 by the elastic member 51. Because of the slide slot 411, the portion of the cylinder 41 of the compressor cylinder 40 radially corresponding to the slide slot 411 is a weaker portion of the cylinder 41, so that a certain damage may be generated to the compressor cylinder 40 under the long-term action of the elastic member 51. The limiting protrusion 5221 is disposed on the inner wall surface of the first plate 522, and can strengthen the cylinder 41 of the compressor cylinder 40, thereby enhancing the strength of the cylinder 41 of the compressor cylinder 40, and preventing the compressor cylinder 40 from being damaged under the action force of the elastic member 51.

Therefore, the limiting protrusion 5221 is provided on the inner wall surface of the first plate 522, so that the connection between the elastic member 51 and the inner wall surface of the first plate 522 is more convenient and stable, and the strength of the cylinder 41 of the compressor cylinder 40 is enhanced, so that the compressor cylinder 40 is not easily damaged under the action force of the elastic member 51.

The shape and number of the stopper protrusions 5221 are not limited here.

In some alternative embodiments, the shape of the retention knob 5221 can be cylindrical, frustoconical, rectangular, or other irregular shape.

In some alternative embodiments, the spacing protrusion 5221 is disposed at a mid-portion of the inner wall surface of the first plate 522.

Thus, the limiting projection 5221 is disposed at the middle position of the inner wall surface of the first plate 522, and the first end of the elastic member 51 is connected to the middle position of the inner wall surface of the first plate 522, and the second end is connected to the middle position of the sliding sheet 50. As shown in fig. 5, the middle part of the slide 50 connected with the elastic member 51 is provided with a yielding part, so that the acting force of the elastic member 51 can act on the yielding part at the middle part of the slide 50, so that the slide 50 slides in the slide slot 411 more stably, and is not easy to deviate out of the slide slot 411.

In some alternative embodiments, the position of the stop projection 5221 is vertically above or equal to one third of the length of the first plate 522 and below or equal to two thirds of the length of the first plate 522, based on the bottom plate 521.

In some alternative embodiments, the position of the stop protrusion 5221 can be four-nineths of the length of the first plate 522, one-half of the length of the first plate 522, five-eighths of the length of the first plate 522, and six-eighths of the length of the first plate 522.

When the position of the limiting protrusion 5221 can be half of the length of the first plate 522, that is, the limiting protrusion 5221 is disposed at the middle position of the first plate 522, so that the acting force of the elastic member 51 can act on the middle position of the sliding vane 50, and the sliding of the sliding vane 50 in the sliding vane slot 411 is more stable.

In some alternative embodiments, the bottom plate 521 is provided with a through hole 5211, the through hole 5211 being located at an end of the bottom plate 521 proximate to the first plate 522.

So set up, set up the through-hole 5211 in the one end that the bottom plate 521 is close to first plate 522, through-hole 5211 can be used for the circulation of the inside lubricating oil of compressor cylinder 40 like this, can make the slip of gleitbretter 50 in gleitbretter groove 411 more smooth and easy under the effect of lubricating oil like this. At the same time, the through holes 5211 also make the pressures on the upper and lower sides of the bottom plate 521 the same, thereby making the circulation of the lubricating oil smoother.

The shape and the number of the through holes 5211 are not limited here.

In some alternative embodiments, the shape of the through holes 5211 can be circular, square, triangular, or other irregular shape.

In some alternative embodiments, the number of through holes 5211 is one or more.

In some alternative embodiments, the number of through holes 5211 is 1, 2, 3, 4, 5, 6.

In order to secure the effect of the through holes 5211 on the circulation of the lubricating oil inside the compressor cylinder 40, when the number of the through holes 5211 is set small, for example, when the number of the through holes 5211 is 1, 2 or 3, the aperture of each through hole 5211 may be set relatively large. When the number of the through holes 5211 is set to be large, for example, when the number of the through holes 5211 is 4, 5, or 6, the aperture of each through hole 5211 may be set to be relatively small.

In some alternative embodiments, the spacing structure 52 further includes a second plate 523 and a third plate 524. The second plate 523 has a first end connected to the second end of the bottom plate 521 and a second end connected to the second end of the first plate 522. The first end of the third plate 524 is connected to the third end of the bottom plate 521, and the second end is connected to the third end of the first plate 522.
