Description

Technical Field

[0001] This application relates to the technical field of rotary compressors, and particularly to a sliding vane of a rotary compressor. Background Art

[0002] The cylinder of a rotary compressor is divided into a suction chamber and a compression chamber by a sliding vane. The sliding vane always abuts against a roller under the action of a sliding vane spring, forming a line contact seal. The roller rolls along the inner wall of the cylinder driven by an eccentric shaft, absorbing and compressing gas cyclically. The sliding vane is not only affected by the pressure difference between the suction chamber and the compression chamber, but also rubs against the roller, making it one of the most vulnerable components in the compressor pump body assembly.

[0003] In the prior art, an oil lubrication groove and a supplementary oil groove are provided on the end face of the sliding vane for abutting against the cylinder head to reduce the contact area between the sliding vane and the cylinder head, reduce the mechanical friction suffered by the sliding vane, and reduce the degree of damage to the sliding vane. The lubricating oil in the oil lubrication groove and the lubricating oil in the supplementary oil groove can both lubricate the cylinder head and the sliding vane, improve the lubrication effect, and reduce the mechanical friction suffered by the sliding vane. However, in the prior art, only the contact part between the sliding vane and the cylinder head is lubricated. For the surface where the sliding vane contacts the sliding vane groove, the sliding vane slides up and down in the sliding vane groove, and the gas pressures in the suction chamber and the compression chamber change continuously. The side wall of the sliding vane bears the continuously changing gas pressure, resulting in continuous collision between the sliding vane and the inner wall of the sliding vane groove, which easily causes collision wear of the sliding vane and reduces the service life of the sliding vane. Therefore, those skilled in the art provide a sliding vane of a rotary compressor to solve the problems raised in the above background art. Summary of the Utility Model

[0026] The following is a further detailed description of the present application with reference to the attached Figures 1-4 drawings.

[0027] An embodiment of the present application discloses a vane of a rotary compressor. Referring to Figures 1-4 , a vane of a rotary compressor includes a vane body 1. Lubricating oil grooves 2 are provided on both sides of the vane body 1. Grooves 3 are provided on both sides of the vane body 1. A buffer plate 4 is slidably arranged in the groove 3. The buffer plate 4 is connected to the groove 3 through a sliding component 5. A rolling groove 6 is provided on the side of the buffer plate 4 away from the vane body 1. A plurality of balls 7 are rotatably connected in the rolling groove 6. A buffer component 8 for buffering the buffer plate 4 is provided in the groove 3.

[0028] In this embodiment, when the sliding vane body 1 collides in the sliding vane groove due to the continuously changing pressure, the sliding vane body 1 first drives the ball 7 to contact and collide with the inner wall of the sliding vane groove. Under the rolling cooperation of the ball 7, the collision force of the sliding vane body 1 is reduced. At the same time, under the collision effect, the movement of the buffer plate 4 is driven. During the movement of the buffer plate 4, the buffer assembly 8 is extruded. With the cooperation of the buffer assembly 8, the sliding vane body 1 can be buffered and protected, the collision damage of the sliding vane body 1 is reduced, and the service life of the sliding vane body 1 is improved.

[0029] In a further embodiment, as Figures 1-2 shown, the sliding assembly 5 includes sliders 51 fixedly arranged on both sides of the buffer plate 4. Sliding grooves 52 for the sliders 51 to slide are formed on both sides of the inner wall of the groove 3. The buffer assembly 8 includes a damper 81 fixedly arranged between the groove 3 and the buffer plate 4. A first spring 82 is sleeved on the outer wall of the damper 81.

[0030] When the sliding vane body 1 collides with the inner wall of the sliding vane groove due to pressure change, under the collision effect, the movement of the buffer plate 4 is driven. The buffer plate 4 drives the slider 51 to slide in the sliding groove 52. With the cooperation of the slider 51 and the sliding groove 52, the movement of the buffer plate 4 is kept stable. During the movement of the buffer plate 4, the damper 81 and the first spring 82 are extruded. Thus, with the cooperation of the damper 81 and the first spring 82, the sliding vane body 1 can be buffered and protected, the collision damage of the sliding vane body 1 is reduced, and the service life of the sliding vane body 1 is improved.

[0031] In a further preferred embodiment of the present utility model, as Figure 1 shown, a connecting plate 9 fixed in the sliding vane groove is provided at the top end of the sliding vane body 1. A second spring 10 is fixed at the bottom end of the connecting plate 9. A clamping head 11 is fixed at the bottom end of the second spring 10. A clamping groove 12 adapted to the clamping head 11 is formed at the top end of the sliding vane body 1. A fixing assembly 13 is provided at the top end of the clamping head 11.

[0032] When the sliding vane body 1 is installed, the clamping head 11 is inserted into the clamping groove 12, and then with the cooperation of the fixing assembly 13, the sliding vane body 1 can be fixed. When replacement and disassembly are required, under the reverse movement of the fixing assembly 13, the clamping head 11 is separated from the clamping groove 12, and then the sliding vane body 1 can be disassembled, which is convenient for the disassembly and replacement of the sliding vane body 1 and improves the replacement efficiency of the sliding vane body 1.

[0033] In a further embodiment, as Figures 3-4As shown, the fixing assembly 13 includes a fixing groove 131 opened at the top of the slide body 1, the top of the clamping joint 11 is rotatably connected with a rotating rod 132 located in the fixing groove 131, the bottom end of the rotating rod 132 is fixed with a first limit block 133, the inner wall of the fixing groove 131 is fixed with a second limit block 134 that conflicts with the first limit block 133, the top of the rotating rod 132 is fixed with a rotating plate 135, and the top of the clamping joint 11 is provided with a locking assembly 14 for fixing the rotating plate 135, the locking assembly 14 includes a locking rod 141 threadedly arranged at the top of the rotating plate 135, and the top of the clamping joint 11 is provided with a locking groove 142 adapted to the locking rod 141.

[0034] When installing the slide body 1, the card joint 11 is inserted into the card slot 12, and the rotating rod 132 is inserted into the fixing slot 131. Then, the rotating plate 135 is manually rotated, and the rotating plate 135 drives the rotating rod 132 to rotate. The rotating rod 132 drives the first limit block 133 to rotate, so that the first limit block 133 is rotated to the bottom of the second limit block 134. Under the resistance of the first limit block 133 and the second limit block 134, the rotating rod 132 is fixed in the fixing slot 131, and then the locking rod 141 is manually rotated to insert the locking rod 141 into the locking rod 141. The rotating plate 135 can be fixed in the groove 142, thereby completing the installation of the slide body 1. When the slide body 1 needs to be disassembled, the locking rod 141 is rotated in the opposite direction to separate the locking rod 141 from the locking groove 142, and then the rotating plate 135 is rotated again. The rotating plate 135 drives the rotating rod 132 to rotate again, and the rotating rod 132 drives the first limit block 133 to separate from the second limit block 134. Then the slide body 1 is pulled, and the slide body 1 can be removed, which is convenient for the disassembly and replacement of the slide body 1 and improves the replacement efficiency of the slide body 1.

[0035] The implementation principle of a rotor compressor vane of the embodiment of the present application is as follows: when the vane body 1 moves in the vane groove, the pressure change in the vane groove drives the vane body 1 to collide with the inner wall of the vane groove, and the vane body 1 drives the ball 7 on the buffer plate 4 to contact the inner wall of the vane groove first, and under the rolling cooperation of the ball 7, the collision force of the vane body 1 is reduced. At the same time, under the action of the collision, the buffer plate 4 is driven to move. The damper 81 and the first spring 82 are squeezed during the movement of the buffer plate 4, and the vane body 1 can be buffered under the cooperation of the damper 81 and the first spring 82. The impact protection reduces the collision damage of the sliding plate body 1 and increases the service life of the sliding plate body 1. When the sliding plate body 1 needs to be replaced, the locking rod 141 is rotated to separate the locking rod 141 from the locking groove 142, and then the rotating plate 135 is rotated. The rotating plate 135 drives the rotating rod 132 to rotate, and the rotating rod 132 drives the first limit block 133 to separate from the second limit block 134. Then the sliding plate body 1 is pulled, the sliding plate body 1 can be removed, and then the new sliding plate body 1 can be installed. It is convenient to disassemble and replace the sliding plate body 1, and the replacement efficiency of the sliding plate body 1 is improved.

[0036] The above are all the preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
