[0031] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0034] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0035] like Figure 1 As shown, a specific implementation of the oocyte transportation device provided in this embodiment includes: a constant temperature box 1, a loading box 5, a longitudinal shockproof component 3, a clamping component 7 and a horizontal shockproof component 6, the constant temperature box 1 has a box body 101 and an openable box cover 102; the loading box 5 is arranged in the constant temperature box 1, and the loading box 5 has a plurality of loading holes for inserting the cryopreservation carrying rod 2; the longitudinal shockproof component 3 is arranged on the inner bottom wall of the constant temperature box 1, and the longitudinal shockproof component 3 has a contact plate 4 for supporting the bottom of the loading box 5; the clamping component 7 is arranged on the inner top wall of the box cover 102 of the constant temperature box 1, and the clamping component 7 has a clamping plate 8 for clamping the cryopreservation carrying rod 2 on the loading box 5; the horizontal shockproof component 6 is arranged on the inner side wall of the constant temperature box 1, and a plurality of horizontal shockproof components 6 are arranged around the loading box 5, and the horizontal shockproof component 6 has a top rod 601 for abutting against the outer side wall of the loading box 5.
[0036] The oocyte transport device provided in this embodiment elastically supports the loading box 5 through the longitudinal shockproof component 3 in the constant temperature box 1, elastically presses the cryopreservation carrying rod 2 on the loading box 5 through the clamping component 7, and elastically supports the side wall of the loading box 5 through the horizontal shockproof component 6, thereby fully shockproofing the cryopreservation carrying rod 2 on the loading box 5 to avoid vibration or collision of the oocytes during transportation.
[0037] like Figure 2As shown, in the oocyte transport device provided by this embodiment, after the cryopreservation carrier rod 2 is inserted into the loading box 5, liquid nitrogen is arranged inside the loading box 5, so as to cryopreserve the oocytes in the cryopreservation carrier rod 2; after the cryopreservation carrier rod 2 is inserted into the loading hole of the loading box 5, the upper part of the cryopreservation carrier rod 2 is supported on the mouth of the loading hole, so that the tops of several cryopreservation carrier rods 2 are kept flush, so that when the clamping plate 8 of the clamping assembly 7 is pressed downward, the tops of several cryopreservation carrier rods 2 can be clamped at the same time. In addition, in this embodiment, the loading box 5 is made of aluminum alloy, so it has good heat preservation after the liquid nitrogen is arranged; the clamping plate 8 in the clamping assembly 7 is made of plastic material, and after the cryopreservation carrier rod 2 is clamped, it can also absorb some vibrations due to its certain deformability.
[0038] like Figure 3 , Figure 4 As shown, in the oocyte transport device provided by this embodiment, the contact plate 4 of the longitudinal shockproof component 3 is movably connected to the inner bottom wall of the incubator 1 through the damping column 303. The damping column 303 has a plurality of columns distributed around the center, and the center of the plurality of damping columns 303 is provided with an elastic component, and the elastic component has an elastic force to push the contact plate 4 upward. Specifically, the damping column 303 has four columns, and the four damping columns 303 are arranged at four corners. Through the arrangement of the damping column 303, not only the movable direction of the contact plate 4 can be limited, but also the contact plate 4 can be damped and supported, thereby slowing down the vibration of the loading box 5 supported by the contact plate 4. In addition, in some alternative embodiments, the contact plate 4 can also be connected to the inner bottom wall of the incubator 1 by other conventional means, such as by a telescopic rod, etc. In addition, the number of the damping columns 303 may not be four, for example, it may be three, five, six, etc.
[0039] like Figure 3 , Figure 4As shown, the elastic component includes an airbag 301 and a first elastic member 302. The airbag 301 is fixed between the thermostatic box 1 and the contact plate 4. The first elastic member 302 is installed inside the airbag 301. The first elastic member 302 has an elastic force to support the airbag 301 upward. Specifically, the first elastic member 302 is a compression spring. The contact plate 4 is elastically supported by the setting of the first elastic member 302, so that the loading box 5 supported by the contact plate 4 can be cushioned during transportation. In addition, in some alternative embodiments, the first elastic member 302 can also adopt other elastic members other than compression springs, such as elastic rubber. In addition, in some alternative embodiments, the elastic component can also adopt other conventional structures, such as only a spring. In this embodiment, the contact plate 4 can be further damped by the setting of the airbag 301, thereby reducing the vibration of the loading box 5 supported by the contact plate 4.
[0040] like Figure 3 As shown, the bottom of the loading box 5 has an embedding groove for embedding the contact plate 4. The arrangement of the embedding groove can enhance the fit between the contact plate 4 and the loading box 5. Specifically, the size of the embedding groove is larger than the size of the support plate, so that after the support plate is embedded in the embedding groove, it can also slide within a certain range in the embedding groove, so as to provide the loading box 5 with a certain horizontal shaking space.
[0041] like Figure 5 As shown, in the oocyte transport device provided in this embodiment, the push rod 601 of the horizontal anti-vibration assembly 6 is laterally slidably embedded on the inner wall of the incubator 1, and the tail of the push rod 601 is connected to a second elastic member 602, and the second elastic member 602 has an elastic force to drive the push rod 601 to be ejected toward the loading box 5. Specifically, the second elastic member 602 can be a compression spring, or other elastic structures, such as elastic rubber.
[0042] like Figure 5 As shown, the end of the push rod 601 facing the loading box 5 is an arc-shaped surface. Such a configuration can be more conducive to the sliding between the push rod 601 and the outer wall surface of the loading box 5. Specifically, the head of the push rod 601 can be a ball head structure.
[0043] like Figure 1 As shown, in the oocyte transport device provided in this embodiment, the pressing plate 8 of the pressing assembly 7 is installed on the inner top wall of the box cover 102 through the third elastic member 703. The third elastic member 703 allows the pressing plate 8 of the pressing assembly 7 to maintain a certain elastic pressing force after pressing the cryopreservation carrier rod 2, thereby cooperating with the longitudinal shockproof assembly 3 to improve the elastic buffering capacity of the loading box 5.
[0044] like Figure 6 As shown, the third elastic member 703 includes a telescopic rod and a spring arranged inside the telescopic rod, one end of the telescopic rod is rotatably connected to the inner top wall of the box cover 102, and the other end of the telescopic rod is rotatably connected to the clamping plate 8. Specifically, the telescopic rod includes a sleeve 702 and a slide bar 701 slidably arranged in the sleeve 702, one end of the slide bar 701 is a ball head structure, which is rotatably mounted on the inner top wall of the box cover 102, and one end of the sleeve 702 is also a ball head structure, which is rotatably mounted on the clamping plate 8; and the rotatable angles of the slide bar 701 and the sleeve 702 on the inner top wall of the box cover 102 and the clamping plate 8 are limited, so that the clamping plate 8 can be horizontally shaken within a certain angle range relative to the box cover 102, thereby adapting to the shaking of the loading box 5 and providing a movable space for the buffering of the loading box 5 in the horizontal direction. Specifically, the ball head structure of the slide rod 701 can be more embedded in the inner top wall of the box cover 102, thereby limiting the shaking space of the slide rod 701 through the inner top wall, and the ball head structure of the sleeve 702 can be more embedded in the clamping plate 8, thereby limiting the shaking space of the sleeve 702 through the clamping plate 8.
[0045] In this embodiment, the box cover 102 cooperates with the box body 101 by rotating, that is, a rotating shaft is provided on one side of the box cover 102 and the box body 101, so that the box cover 102 can be opened or closed around the rotating shaft; at the same time, in order to lock the box cover 102, a locking structure can be provided on the side away from the rotating shaft, and specifically a snap-on locking structure can be provided. Of course, in some other alternative embodiments, the box cover 102 can also be opened in other ways, for example, a direct buckling method can be adopted, that is, the box cover 102 is directly buckled onto the box body 101 vertically, and then locking structures are provided on all sides. In this way, the box cover 102 can be completely removed, so as to facilitate the placement and removal of the loading box 5.
[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present utility model.
