[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0029] Reference Figure 1-Figure 6 A high-strength composite plastic massage chair shaft cover, comprising a fixed sleeve 1, a connecting thread groove 3 is provided inside the bottom end of the fixed sleeve 1, so that the fixed sleeve 1 can be threadedly connected and assembled with the outer fixed shell of the massage chair bearing through the connecting thread groove 3, and a sealing ring can be arranged between the fixed sleeve 1 and the outer fixed shell of the massage chair bearing as needed, thereby improving the sealing effect between the fixed sleeve 1 and the outer fixed shell of the massage chair bearing, and a sealing platform 2 is slidably connected inside the top end of the fixed sleeve 1, so that the sealing platform 2 can be installed inside the top end of the fixed sleeve 1;

[0030] In other embodiments, the connecting thread groove 3 can be opened on the outer side of the bottom end of the fixing sleeve 1, so that the fixing sleeve 1 can be threadedly connected with the inner side of the fixing shell outside the massage chair bearing through the connecting thread groove 3 on the outer side of the bottom end.

[0031] A plurality of annular sealing strips 5 are fixed to the bottom of the sealing platform 2. The material of the annular sealing strips 5 is silicone. Thus, a sealing effect is formed between the bottom of the sealing platform 2 and the fixed sleeve 1 through the annular sealing strips 5. The sealing effect can be adjusted according to the number of the annular sealing strips 5. An adjusting cavity 6 is provided inside the sealing platform 2. Injection cavities 9 are provided inside the sealing platform 2 and at both ends of the adjusting cavity 6. The adjusting cavity 6 and the injection cavity 9 are connected, so that the same object can move between the adjusting cavity 6 and the injection cavity 9. A first through hole 7 is provided inside the sealing platform 2 and at the bottom of the injection cavity 9. A second through hole 8 is provided inside the annular sealing strip 5 and at the bottom of the first through hole 7. The first through hole 7 and the second through hole 8 are connected, so that an object can enter the inside of the second through hole 8 through the first through hole 7 and contact the bearing through the second through hole 8.

[0032] Both ends of the adjusting chamber 6 are slidably connected with translation plates 10, which are L-shaped. The translation plates 10 are slidably connected with the fixed sleeve 1. An annular positioning groove 4 is provided inside the top of the fixed sleeve 1. The translation plates 10 and the fixed sleeve 1 are slidably connected through the annular positioning groove 4, so that after the translation plates 10 enter the annular positioning groove 4, the height of the sealing platform 2 inside the annular positioning groove 4 can be fixed. The tops and bottoms of the two translation plates 10 away from each other at one end are provided with extrusion slopes 17, so that the translation plates 10 can easily enter the annular positioning groove 4 through the extrusion slopes 17;

[0033] A sealing block 16 is fixed at the bottom of the translation plate 10 and located inside the injection cavity 9, so that the top of the first through hole 7 can be sealed by the sealing block 16. An injection through hole 18 is opened at the bottom of the translation plate 10 and located at one end of the sealing block 16, so that when the sealing block 16 is located at the end closest to the adjustment cavity 6, the injection through hole 18 corresponds to the first through hole 7, so that the external lubricating fluid enters the second through hole 8 and the first through hole 7 through the injection through hole 18, thereby lubricating the bearing. At this time, it is not necessary to separate the sealing platform 2 from the fixed sleeve 1, thereby reducing the dust entering the bearing;

[0034] An adjusting mechanism for driving the two translation plates 10 to move in opposite directions is installed inside the sealing platform 2, and the adjusting mechanism includes a displacement driving motor 11, a first bevel gear 12, a second bevel gear 13, a rotating shaft 14 and a threaded column 15. The displacement driving motor 11 is fixed inside the sealing platform 2 and at the top of the adjusting chamber 6, and the first bevel gear 12 is fixed at the output end of the displacement driving motor 11 and located on the inner side of the adjusting chamber 6. The bottom of the first bevel gear 12 is meshed and connected with the second bevel gear 13, and the rotating shaft 14 is fixed inside the second bevel gear 13, so that the rotation of the first bevel gear 12 drives the rotating shaft 14 to rotate synchronously through the second bevel gear 13, and threaded columns 15 are fixed at both ends of the rotating shaft 14, and the threaded rotation directions of the two threaded columns 15 are opposite, and the outer sides of the two threaded columns 15 away from each other are threadedly connected to the translation plate 10, so that the rotation of the two threaded columns 15 drives the two translation plates 10 to move closer or away at the same time.

[0035] In this embodiment, a battery is also fixed inside the sealing platform 2, and the displacement drive motor 11 is driven by the battery to work. In other embodiments, the displacement drive motor 11 can be replaced by a rotating handle passing through the top of the sealing platform 2, and the bottom of the rotating handle is fixed to the first bevel gear 12.

[0036] The use process of a high-strength composite plastic massage chair shaft cover provided by the utility model is as follows: when in use, firstly, the fixing sleeve 1 is threadedly connected and assembled with the outer fixing shell of the massage chair bearing through the connecting thread groove 3, and then the sealing platform 2 is slid into the interior of the top of the fixing sleeve 1, and the sealing effect between the sealing platform 2 and the fixing sleeve 1 is increased by the annular sealing strip 5, and at the same time, the height of the sealing platform 2 inside the fixing sleeve 1 is pre-positioned through the contact between the annular sealing strip 5 and the fixing sleeve 1, and the first bevel gear 12 is driven to rotate by the operation of the displacement driving motor 11, and the rotation of the first bevel gear 12 drives the meshing second bevel gear 13 to rotate, and the rotation of the second bevel gear 13 drives the two threaded columns 15 with opposite thread rotation directions to rotate through the rotating shaft 14, and the rotation of the threaded column 15 drives the threaded translation plate 10 to move, and at this time, the translation plate 10 is allowed to enter the inside of the slidingly connected annular positioning groove 4, and then the height of the sealing platform 2 inside the fixing sleeve 1 is positioned, and the sealing block 16 blocks and seals the top of the first through hole 7;

[0037] When it is necessary to lubricate the bearing protected on the inner side of the fixed sleeve 1, the rotation of the displacement drive motor 11 drives the two translation plates 10 to move closer through the two threaded columns 15, and then the movement of the translation plate 10 drives the sealing block 16 to move, so that the sealing block 16 releases the seal formed by the blockage on the top of the first through hole 7, and at the same time, the injection through hole 18 is made to correspond to the position of the first through hole 7, and then the gun head of the lubrication gun is passed through the injection through hole 18 from the outside into the first through hole 7 and the second through hole 8, thereby lubricating the bearing.
