The maximum outer diameter at the flange 53 is larger than the outer diameter of the bottom end of the cleaning wall 51, i.e., the diameter at the maximum height at which the flange 53 protrudes with respect to the outer surface of the cleaning wall 51 is larger than the outer diameter of the bottom end of the cleaning wall 51. When the cleaning cover 500 is installed, the flange 53 can be always abutted against the inner wall of the outer cover 300, and the risk of falling off when the cleaning cover 500 is not installed in place is avoided.

A handle 54 is provided at the outer side of the bottom end of the cleaning wall 51, and the cleaning cover 500 can be easily detached from the housing 300 by using the handle 54. The bottom end of the outer cover 300 is provided with the groove 340, the handle 54 is positioned in the groove 340, so that the groove 340 can be utilized to facilitate the matching of the handle 54 and the outer cover 300, the matching strength and the attractiveness of the cleaning cover 500 and the outer cover 300 are improved, and the outer cover 300 is prevented from being abutted to the cup holder 400. The handle 54 and the groove 340 may be engaged to improve the coupling strength between the cleaning cover 500 and the outer cover 300.

In the embodiment, the cleaning cover 500 is formed by a flexible material , the cleaning cover 500 is made of the flexible material, the cleaning cover 500 can be conveniently installed in the outer cover 300 by utilizing the flexibility of the cleaning cover 500, meanwhile, the cleaning cover 500 is tightly attached to the outer cover 300, and the cleaning cover 500 can be conveniently taken down from the outer cover 300, the cleaning cover 500 is integrally formed by , the processing and the preparation are convenient, the structural strength among all parts of the cleaning cover 500 is improved, and the cleaning cover 500 can be used for times and can be cleaned for multiple times for repeated use.

In the above embodiment, the cleaning cover 500 and the outer cover 300 are in interference fit, and the flange 53 is disposed on the outer side of the cleaning cover 500 to be matched with the groove 330 of the outer cover 300, so as to achieve the detachable connection between the cleaning cover 500 and the outer cover 300. here, as another embodiment, the flange 53 may not be disposed on the outer side of the cleaning cover 500, and the detachable connection with the outer cover 300 is achieved only by interference fit.

In another embodiment of the present invention, the cleaning cover 500 may be identical to the previous embodiments, and the main structure of the thrombelastogram apparatus is substantially the same as the previous embodiments, and the differences will be described in detail below.

As shown in fig. 5 and fig. 6, in this embodiment, the thromboelastogram apparatus further includes a cup withdrawing block 600, the cup withdrawing block 600 is slidably connected to the fixing base 100 along the axial direction of the rotating shaft 200, when the cup withdrawing block 600 moves towards the inner cup 901 relative to the rotating shaft 200, the bottom end of the cup withdrawing block 600 can abut against the inner cup 901, so that the inner cup 901 moves downwards relative to the rotating shaft 200;

the cup withdrawing block 600 is provided with a cup withdrawing ring 61, when the cup withdrawing block 600 moves towards the inner cup 901 relative to the rotating shaft 200, the cup withdrawing ring 61 abuts against the cleaning ring 52 of the cleaning cover 500 to enable the cleaning cover 500 to move downwards relative to the outer cover 300, and further the flange 53 moves out of the groove 330 and abuts against the inner wall of the outer cover 300.

By using the cup withdrawing ring 61, when the cup withdrawing operation of the inner cup 901 is performed, can be performed and the cleaning cover 500 can be detached, and the flange 53 can still abut against the inside of the outer cover 300, so that the cleaning cover 500 is not completely detached, the cleaning cover 500 is prevented from directly falling off, and the user can completely detach the cleaning cover 500 through the handle 54.

The maximum outer diameter of the flange 53 is larger than the outer diameter of the bottom end of the cleaning wall 51, and when the cleaning cover 500 is positioned in the outer cover 300, the flange 53 can always keep abutting against the inner wall of the outer cover 300, so that the cleaning cover 500 is effectively ensured to directly fall off.

In the axial direction of the rotating shaft 200, a distance exists between the cup withdrawing ring 61 and the bottom end face of the cup withdrawing block 600, when the bottom end of the cup withdrawing block 600 moving downwards abuts against the inner cup 901, a gap still exists between the cup withdrawing ring 61 and the cleaning ring 52, when the cup withdrawing block 600 continues moving downwards, the inner cup 901 is disengaged from the rotating shaft 200, the cup withdrawing ring 61 abuts against the cleaning ring 52 again, and when the cup withdrawing ring 61 moves downwards in step, the flange 53 is moved out from the groove 330.

In the above embodiment, the inner diameter of the cleaning ring 52 is larger than the outer diameter of the top end of the inner cup 901 to facilitate the deformation of the top end of the cleaning cap 500 into the outer cap 300. Here, in other embodiments, the inner diameter of the cleaning ring 52 may be smaller than the outer diameter of the top end of the inner cup 901 to further prevent blood to be measured from splashing on the components above the inner cup 901.

The above embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
