Description

Technical Field

[0001] The utility model relates to the technical field of replacement covers, in particular to a replacement cover for a biochemical analyzer assembly line. Background Art

[0002] The process of testing the blood in the blood collection tube on the biochemical analyzer assembly line is carried out during the circulation process. First, the cap with a relatively complex structure at the mouth of the blood collection tube is removed, and then a replacement cap with a simple structure is replaced to prevent blood from overflowing from the blood collection tube during the circulation process.

[0003] In the prior art, a ring groove is provided on the flange edge so that the cap can be automatically arranged when being put on the machine. An axial opening groove is provided on the circumference of the conical sealing ring edge, which increases the elastic deformation of the conical sealing ring edge and performs sealing. However, in actual use, firstly, the gas in the conical sealing ring is certain, and the volume of the conical sealing ring that can be plugged into the bottle mouth is only slightly larger than the bottle mouth. When the external temperature changes and the air pressure in the bottle increases, the pressure may spray the replacement cap out of the bottle mouth, and the sealing degree is weak. Secondly, after sealing by the conical sealing ring, the conical sealing ring is tightly plugged in the collection tube, which is inconvenient when the replacement cap needs to be pulled out. Therefore, it is necessary to improve a replacement cap for a biochemical analyzer assembly line to solve the above problems. Utility Model Content

[0027] The sealing mechanism 4 includes a power assembly 41 and a sealing assembly 42 . The power assembly 41 is disposed inside the cover body 1 , and the sealing assembly 42 is disposed inside the cover body 1 .

[0028] Furthermore, the power assembly 41 includes two rotating plates 411, and the two rotating plates 411 are both rotatably installed inside the cover body 1, and the rotating rods 412 are rotatably installed inside the two rotating plates 411. Two fixed columns 413 are fixedly installed inside the cover body 1, and springs A414 are fixedly installed inside the two fixed columns 413. A sliding column 415 is fixedly installed on the end of the spring A414 away from the fixed column 413, and two limit blocks 416 are fixedly installed on the outside of the sliding column 415. A moving block A417 is fixedly installed on the end of the sliding column 415 away from the limit block 416, and a protrusion 418 is fixedly installed on the side of the moving block A417 close to the rotating rod 412, and a sealing ring A419 is fixedly installed on the outside of the moving block A417, so that gas will not leak when the moving block A417 moves.

[0029] Furthermore, the sealing ring A419 is slidably installed inside the cover body 1, the limit block 416 is slidably installed inside the fixed column 413, the sliding column 415 is slidably installed inside the fixed column 413, and the end of the rotating rod 412 away from the rotating plate 411 is rotatably installed inside the protrusion 418, driving the protrusion 418 to move.

[0030] Furthermore, the sealing assembly 42 includes two conical sealing rings 421, and the two conical sealing rings 421 are fixedly installed on the outside of the cover body 1. Two rectangular grooves 422 are provided inside the two conical sealing rings 421. A conveying cavity 423 is provided inside the cover body 1, and two diversion cavities 424 are provided inside the cover body 1. A connecting cavity 425 is provided inside the cover body 1 to facilitate the gas in the moving cavity of the moving block A417 to be injected into the conveying cavity 423.

[0031] Furthermore, the connecting cavity 425 is connected to the conveying cavity 423, and the rectangular groove 422 corresponds to the diverting cavity 424 to carry out gas conveyance. Example

[0032] See also Figure 6 In combination with Example 1, it is further obtained that the exhaust and injection mechanism 5 includes two springs B51, the two springs B51 are fixedly installed inside the cover body 1, a moving block B52 is fixedly installed at one end of the two springs B51 away from the cover body 1, a sealing ring B53 is fixedly installed outside the moving block B52, and a through hole 54 is opened inside the cover body 1 to facilitate the injection and discharge of gas.

[0033] Furthermore, the through hole 54 is connected to the delivery cavity 423, and the sealing ring B53 is slidably installed inside the cover body 1, so that the gas will not leak out when the moving block B52 moves.

[0034] In actual operation, when this device is used, an annular groove 3 is provided on the outside of the flange edge 2, so that it can be automatically arranged when being put on the machine, without manual placement, thereby speeding up work efficiency.

When the device is moved to the corresponding position above the bottle mouth, the device is pressed down, the cover body 1 is inserted into the bottle mouth, and the rotating plate 411 contacts the inner side of the bottle mouth. As the cover body 1 moves downward, the two rotating plates 411 rotate inside the cover body 1, driving the rotating rod 412 to rotate and push the protrusion 418 to move, so that the two protrusions 418 drive the two moving blocks A417 to move inward to push the gas, so that the gas in the moving cavity of the moving block A417 is injected into the conveying cavity 423, and then injected into the two conical sealing rings 421 through the two diversion cavities 424 and the rectangular groove 422, so that the conical sealing ring 421 expands more thoroughly, making the conical sealing ring 4 21 is stuck in the bottle mouth, completing the sealing installation of the device to prevent blood from overflowing from the blood collection tube during the circulation process. The sealing ring A419 prevents gas from leaking when the moving block A417 moves. When the device needs to be removed from the bottle mouth, the moving block B52 is pressed down to compress the spring B51, so that the through hole 54 is located above the moving block B52 and connected to the outside world. The gas inside the conical sealing ring 421 passes through the diversion cavity 424 and the conveying cavity 423, and is finally discharged through the through hole 54, so that the volume of the conical sealing ring 421 becomes smaller, which is convenient for pulling the device out of the bottle mouth. The moving block B52 is released, and the sealing ring B53 rebounds to drive the moving block B52 to reset. The device can be cleaned. After cleaning, the moving block B52 is pressed down, and a proper amount of gas is injected into the conveying cavity 423 through the through hole 54, and it can be used again. The sealing ring B53 prevents gas from leaking when the moving block B52 moves.
