[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a specimen turntable drive mechanism for a fully automatic liquid-based cell preparation and staining machine, comprising a staining machine 1, an oil storage pipe 2 fixedly connected to the inner wall of the staining machine 1, the oil storage pipe 2 storing a certain amount of lubricating oil for immediate use, a moving mechanism provided on the inner wall of the oil storage pipe 2, a contact block 5 fixedly connected to the right end of the moving mechanism, the contact block 5 having the same shape as the gear 12, allowing the gear 12 to compress the contact block 5 to cause it to move, an oil inlet hole 7 at the top of the moving mechanism allowing lubricating oil to enter the moving pipe 4 through the oil inlet hole 7, and an air bladder 8 fixedly connected to the top of the oil storage pipe 2, the air bladder 8 communicating with the oil storage pipe 2 to allow air to be supplied. During compression, the oil enters the air bladder 8, which is inflatable. The top of the oil storage tube 2 is fixedly connected to the oil guide tube 9, which is connected to the oil storage tube 2. This allows lubricating oil to be replenished into the oil storage tube 2 through the oil guide tube 9. The top of the oil guide tube 9 is fixedly connected to the scale tube 10, which is the oil inlet and has scale lines on its surface. Lubricating oil can be poured in through the scale tube 10, and the oil usage can be observed through the scale lines. The top inner wall of the staining machine 1 is rotatably connected to the turntable 11, which holds specimen cups, slide preparation chambers, etc. It can simultaneously carry multiple specimens for processing, facilitating batch operations on a large number of samples and improving work efficiency. The lower outer wall of the turntable 11 is fixedly connected to the gear 12, and the inner wall of the oil storage tube 2 is equipped with a sealing component.

[0032] Reference Figure 2 - Figure 4 The sealing assembly includes a connecting rod 13, which is slidably connected to the inner wall of the oil reservoir 2. The oil reservoir 2 has a corresponding slot for the connecting rod 13, allowing it to move vertically along the slot. The inner sidewall of the connecting rod 13 is elastically connected to the oil reservoir 2 via a positioning spring 14. A float plate 15 is fixedly connected to the bottom end of the connecting rod 13. The float plate 15 is made of EVA (ethylene-vinyl acetate copolymer) material, and its displacement of lubricating oil exceeds its own weight, generating sufficient buoyancy to make it float above the lubricating oil. On the surface, the inner side wall of the connecting rod 13 is fixedly connected to one end of the positioning spring 14. At this time, the positioning spring 14 is in its initial state. When the connecting rod 13 moves downward, it will compress the positioning spring 14. When resetting, the elastic force of the positioning spring 14 will carry the connecting rod 13 upward to reset. The other end of the positioning spring 14 is fixedly connected to the top end of the oil reservoir 2. The float plate 15 is inserted into the inner wall of the oil guide pipe 9. The top end of the float plate 15 is a circular protrusion that is the same as the groove on the inner wall of the oil guide pipe 9, so that the protrusion can be inserted into the inner wall of the oil guide pipe 9.

[0033] Reference Figure 2 - Figure 4The graduated tube 10 is fixedly connected to the left side wall of the dyeing machine 1. The moving mechanism includes a moving tube 4, which is slidably connected to the inner wall of the oil storage tube 2. The oil storage tube 2 has a corresponding slot for the moving tube 4, allowing the moving tube 4 to move left and right. The inner side wall of the moving tube 4 is elastically connected to the oil storage tube 2 via a return spring 3. A rubber ring 6 is fixedly connected to the left end of the moving tube 4. The rubber ring 6 is made of rubber, and the inner wall of the oil storage tube 2 has a corresponding sealing opening, allowing the rubber ring 6 to be inserted into the opening to ensure the sealing between the oil storage tube 2 and the moving tube 4. The inner side wall of the moving tube 4 is fixedly connected to one end of the return spring 3. When the moving tube 4 moves to the left, it will compress the return spring 3. When resetting, the elastic force of the return spring 3 will carry the moving tube 4 to reset. The other end of the return spring 3 is fixedly connected to the right side wall of the oil storage tube 2. The oil inlet 7 is opened on the inner wall of the moving tube 4. The contact block 5 is fixedly connected to the right side wall of the moving tube 4. The contact block 5 is connected to the moving tube 4, allowing lubricating oil to enter the contact block 5 from the moving tube 4. The right side wall of the rubber ring 6 is in contact with the right inner wall of the oil storage tube 2. The contact block 5 is inserted into the outer wall of the gear 12.

[0034] Working principle: When gear 12 needs to be lubricated, simply drive the external electrical control device to make gear 12 rotate with turntable 11. This causes the outer wall of gear 12 to press against the arc surface of contact block 5, and contact block 5 to move to the left along with moving tube 4 and rubber ring 6. At this time, the return spring 3 is compressed, allowing oil in oil storage tube 2 to enter moving tube 4 through oil inlet 7 and be delivered to contact block 5. When the arc of contact block 5 coincides with the arc of the next gear 12, the reverse elastic force of return spring 3 is used to reset moving tube 4 and contact block 5, allowing the lubricating oil in contact block 5 to lubricate the arc of the outer wall of gear 12 through the small hole, ensuring the stability of gear 12 transmission on turntable 11.

[0035] When the lubricating oil in the oil reservoir 2 drops below the level of the float plate 15, the float plate 15 loses its buoyancy. The weight of the lubricating oil in the graduated tube 10 and the guide tube 9 then forces it into the oil reservoir 2. The weight of the lubricating oil impacts the float plate 15, causing it to separate from the inner wall of the guide tube 9. This allows the float plate 15, along with the connecting rod 13, to move downwards and compress the positioning spring 14, allowing lubricating oil to enter the oil reservoir 2. When the level in the oil reservoir 2 reaches the position of the float plate 15, the float plate 15 gains buoyancy and, in conjunction with the counterforce of the positioning spring 14, returns to its original position, causing the float plate 15 to return to its original position. Figure 4 As shown, it can automatically replenish the lubricating oil in the oil reservoir 2.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
