[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] The sliding structure of this embodiment includes: a cylinder block component 1, which has a receiving cavity 12 and a communication channel 11 communicating with the receiving cavity 12; a sliding component 2, which includes a roller part 21 located in the receiving cavity 12 and a sliding part 22 inserted in the communication channel 11. The roller part 21 is connected to the sliding part 22, and the sliding part 22 includes a sliding side wall 23 slidably connected to the inner wall of the communication channel 11. Among them, the sliding part 22 includes an oil guiding channel 221, an oil inlet 222, and an oil outlet 223. The oil inlet 222 and the oil outlet 223 are connected through the oil guiding channel 221. The oil inlet 222 is located at one end of the sliding part 22 away from the roller part 21, and the oil outlet 223 is located on the sliding side wall 23. With the above settings, when the compressor operates, the sliding component 2 moves up and down, and the oil passes through the oil inlet 222 from the outside of the sliding component 2 and enters the inside of the sliding component 2 through the oil guiding channel 221, and then from the inside of the sliding component 2, passes through the oil guiding channel 221 to reach the oil outlet 223. Through the oil outlet 223, the oil in the oil guiding channel 221 reaches between the sliding side wall 23 of the sliding part 22 and the communication channel 11 of the cylinder block component 1, playing a lubricating role, thereby avoiding the phenomenon of jamming when the sliding part 22 slides, and solving the problem that the sliding vane in the compressor in the prior art is prone to jamming.

[0029] In the sliding structure of this embodiment, referring to Figure 1 , the sliding structure further includes a base 3, which plays a fixing role. The base 3 is connected to the cylinder block component 1. There is an oil inlet cavity 4 between the base 3 and the sliding part 22. The oil inlet cavity 4 is communicated with the oil guiding channel 221. The oil inlet cavity 4 is used to store oil. When the compressor pump body works normally, through the movement of the sliding part 22, the oil flows between the oil inlet cavity 4 and the oil guiding channel 221, playing a lubricating role to avoid wear of the compressor pump body components.

[0030] In the sliding structure of this embodiment, referring to Figures 2 to 5 , the sliding structure further includes an oil rod component 5. The oil rod component 5 is connected to the base 3. The oil rod component 5 includes a pushing part 51 for being inserted into the oil guiding channel 221. When the sliding part 22 slides in the communication channel 11, the pushing part 51 moves relative to the side wall of the oil guiding channel 221. When the sliding part 22 rises to the limit position, the oil rod component 5 is communicated with the oil guiding channel 221, and the oil flows from the oil inlet cavity 4 to the oil guiding channel 221. The oil plays a lubricating role and reduces wear of components.

[0031] In the sliding structure of this embodiment, referring to Figures 1 to 3 、 Figure 7, the oil guiding channel 221 includes a sealing section 2211, and the pushing part 51 includes an avoiding state located outside the sealing section 2211 and a plugging state inserted into the sealing section 2211; when the sliding part 22 rises to the extreme position, the pushing part 51 avoids the sliding part 22, and the oil fluid enters the oil guiding channel 221 from the oil inlet cavity 4; when the sliding part 22 descends to the extreme position, the pushing part 51 plugs the sealing section 2211, and the pushing part 51 is slidably connected to the inner wall of the oil guiding channel 221, so as to squeeze the oil in the oil guiding channel 221. In this way, the pushing part 51 can ensure that the oil fluid in the oil inlet section 2212 flows towards the oil outlet 223, ensuring the lubrication efficiency, reducing component wear, and increasing the service life of the equipment.

[0032] In the sliding structure of this embodiment, refer to Figure 1 , Figure 3 , Figure 7 , the oil guiding channel 221 includes an oil inlet section 2212, the oil inlet section 2212 is connected to one end of the sealing section 2211 close to the oil inlet cavity 4, and there is an oil inlet gap between the inner wall of the oil inlet section 2212 and the pushing part 51. When the sliding part 22 rises to the extreme position, the oil fluid enters the sealing section 2211 from the oil inlet cavity 4 after passing through the oil inlet section 2212; when the sliding part 22 descends to the extreme position, the pushing part 51 leaves the sealing section 2211. In this way, the external oil fluid can flow into the sealing section 2211 and thus reach the oil outlet 223.

[0033] In the sliding structure of this embodiment, refer to Figure 1 , Figure 5 , the sealing section 2211 is a cylindrical channel; the pushing part 51 is a cylindrical structure, which is beneficial to the smooth movement of the pushing part 51.

[0034] In the sliding structure of this embodiment, refer to Figure 1 , Figure 3 , the oil rod component 5 includes a connecting seat 52, the connecting seat 52 is connected to the base 3, the pushing part 51 is connected to the connecting seat 52, the sliding structure further includes an elastic member 6, one end of the elastic member 6 is connected to the sliding part 22, one end of the elastic member 6 is connected to the connecting seat 52, the elastic member 6 is sleeved on the pushing part 51, and the pushing part 51 performs a reciprocating linear motion between the upper and lower extreme positions in the accommodating cavity 12 to enable the normal operation of the compressor.

[0035] Specifically, the elastic member 6 in this embodiment is a spring.

[0036] In the sliding structure of this embodiment, refer to Figure 1 , Figure 7, the sliding part 22 includes a connecting groove 224. The bottom of the connecting groove 224 is used to abut against the elastic member 6. Along the direction of the oil inlet cavity 4 approaching the base 3, the cross-sectional area of the connecting groove 224 gradually increases, so that on the basis of fixing the elastic member 6, the oil liquid flows from the oil inlet cavity 4 into the connecting groove 224 and then flows to the oil guiding channel 221, thus playing a lubricating role.

[0037] In the sliding structure of this embodiment, refer to Figures 6 to 8 , the oil guiding channel 221 includes a first oil guiding channel 2213 and a second oil guiding channel 2214 that are communicated with each other. The first oil guiding channel 2213 extends along the sliding direction of the sliding part 22, and the oil inlet 222 is arranged on the first oil guiding channel 2213. The second oil guiding channel 2214 is arranged through the sliding part 22, and an oil outlet 223 is arranged at each of the opposite ends of the second oil guiding channel 2214. When the sliding part 22 rises to the limit position, the oil inlet 222 is opened, and the oil liquid enters the sliding part from outside the sliding part through the oil inlet; when the sliding part 2 descends to the lower limit, the oil inlet 222 is closed, and the oil guiding channel 221 is squeezed, and its internal space becomes smaller and smaller. Thus, the oil liquid reaches the contact surface between the inner wall of the sliding part 22 and the pushing part 51 through the oil outlet, thereby improving the lubrication effect and prolonging the service life of the compressor.

[0038] In some embodiments, there are multiple first oil guiding channels 2213, and the multiple first oil guiding channels 2213 are arranged at intervals.

[0039] In some embodiments, there are multiple second oil guiding channels 2214, and the multiple second oil guiding channels 2214 are arranged at intervals.

[0040] The compressor of this embodiment includes a sliding structure, and the sliding structure is the above-mentioned sliding structure to play a lubricating role, reduce component wear, and thus prolong the service life of the compressor.

[0041] A description of an embodiment of the sliding structure of the present invention is as follows:

[0042] The sucker rod component 5 is tightly fitted and fixed inside the elastic component 6. The tail of the elastic component 6 abuts against the connecting seat at the tail of the sucker rod component 5 for position limitation. The sucker rod component 5 is assembled in cooperation with the oil guiding channel 221. When the sliding component 2 rises to the limit position, the oil inlet 222 of the part where the sucker rod component 5 cooperates with the oil guiding channel 221 communicates with the oil guiding channel 221, and the oil fluid enters from the outside of the sliding component 2 into the inside of the sliding component 2. When the sliding component 2 descends to the lower limit position, the sucker rod component 5 isolates the oil guiding channel 221 from the oil inlet 222. During the downward movement of the sliding component 2, due to the extrusion of the sucker rod component 5 on the first oil guiding channel 2213 and the second oil guiding channel 2214, the internal spaces of the first oil guiding channel 2213 and the second oil guiding channel 2214 become smaller and smaller, so as to squeeze the oil fluid in the oil guiding channel 221 to between the sliding side wall 23 of the sliding part 22 and the communication channel 11 of the cylinder block component 1 through the oil outlet 223, playing a lubricating role.

[0043] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0044] The sliding structure of the present invention includes a cylinder block component 1, which has a receiving cavity 12 and a communication channel 11 communicating with the receiving cavity 12; a sliding component 2, which includes a roller part 21 located in the receiving cavity 12 and a sliding part 22 penetrating through the communication channel 11. The roller part 21 is connected to the sliding part 22, and the sliding part 22 includes a sliding side wall 23 slidably connected to the inner wall of the communication channel 11. Among them, the sliding part 22 includes an oil guiding channel 221, an oil inlet 222 and an oil outlet 223. The oil inlet 222 and the oil outlet 223 are communicated through the oil guiding channel 221. The oil inlet 222 is located at one end of the sliding part 22 away from the roller part 21, and the oil outlet 223 is located on the sliding side wall 23. With the above arrangement, when the compressor operates, the sliding component 2 moves up and down, and the oil fluid enters from the outside of the sliding component 2 through the oil inlet 222 into the inside of the sliding component 2 through the oil guiding channel 221, and then from the inside of the sliding component 2, reaches the oil outlet 223 through the oil guiding channel 221. Through the oil outlet 223, the oil fluid in the oil guiding channel 221 reaches between the sliding side wall 23 of the sliding part 22 and the communication channel 11 of the cylinder block component 1, playing a lubricating role, thereby avoiding the phenomenon of jamming when the sliding part 22 slides and solving the problem that the sliding vane in the compressor in the prior art is prone to jamming.
