[0055] In view of the defects of the prior art, the present application provides a portable box for live bovine ovum collection, which is used for storing and transporting the live bovine ovum collection device. Figures 1-6 As shown in the figure, the portable box for live bovine ovum collection comprises an outer box body 1, an inner box body 2, a slide rail assembly and a support assembly. The outer box body 1 is a hollow cuboid structure, one side wall of the outer box body 1 is open, and the inner box body 1 is inserted into the outer box body 1 through the opening 11.

[0056] The inner box body 2 is a cuboid shell with an open top, used for carrying the live bovine ovum collection device body, and the inner box body 2 can enter and exit the outer box body 1 along the first direction to expose the live bovine ovum collection device body for live ovum collection work. It can be understood that the first direction described in the present embodiment is the direction along the slide rail assembly. Figure 1X direction in the figure.

[0057] The inner box 2 and the outer box 1 are connected by two groups of slide rail assemblies, which are respectively arranged on two opposite sides of the inner box 2 along the first direction. The slide rail assembly comprises a first rail 31 and a second rail 32 arranged along the first direction, the first rail 31 and the second rail 32 are embedded with each other, and the second rail 32 can slide along the first rail 31.

The second rail 32 is combined and fixed to the outer side wall of the inner box 2, which is located on two opposite sides of the inner box 2 along the first direction. The second rail 32 is slidingly connected to the corresponding first rail 31, so that the inner box 2 can enter and exit the outer box 1 along the first rail 31, and the stability of the inner box 2 entering and exiting is ensured.

[0058] The support assembly is combined and fixed to the bottom of the inner box 2, which is used to provide support for the inner box 2 when the inner box 2 is partially located outside the outer box 1, reduce the pressure of the slide rail assembly, and avoid the tipping of the portable box for live bovine oocyte collection caused by the shift of the center of gravity of the portable box for live bovine oocyte collection due to the heavy load in the inner box 2, and avoid the damage of the portable box for live bovine oocyte collection caused by the collision of the portable box for live bovine oocyte collection in the portable box for live bovine oocyte collection.

[0059] The support assembly is located between the inner box 2 and the outer box 1 when the inner box 2 is inserted into the outer box 1, and comprises a mounting block 41, a supporting leg 42, a connecting shaft 43 and a torsional spring 44. The mounting block 41 is combined and fixed to the bottom wall of the inner box 2, and the mounting block 41 is provided with a mounting hole corresponding to the connecting shaft 43. The connecting shaft 43 is rotatably connected to the mounting hole and hingedly connected to the mounting block 41, and can rotate around the second direction. The supporting leg 42 is combined and fixed to the connecting shaft 43 and can rotate with the connecting shaft 43. The torsional spring 44 is sleeved on the connecting shaft 43 and can rotate with the connecting shaft 43, and one end of the torsional spring 44 abuts against the bottom wall of the inner box 2. It can be understood that the second direction in the embodiment is the Y direction in the figure. Figure 1 Y direction in the figure.

[0060] When the inner box 2 is pulled out of the outer box 1, the supporting leg 42 abuts against the horizontal plane to provide support for the inner box 2; when the inner box 2 is retracted into the outer box 1, with the retraction of the inner box 2, the supporting leg 42 contacts the outer box 1 and is pushed by the outer box 1 to rotate clockwise around the second direction, and the supporting leg 42 is converted from the supporting state to the storage state, and in this process, the torsional spring 44 rotates with the connecting shaft 43 to accumulate elastic potential energy; when the inner box 2 is pulled out, the supporting leg 42 is reset under the action of the elastic potential energy of the torsional spring 44, so as to realize the automatic conversion from the storage state to the supporting state.

[0061] In a specific embodiment, as shown in Figure 5As shown, the support assembly comprises two oppositely arranged mounting blocks 41, both ends of the connecting shaft 43 rotatably penetrating the mounting holes of the two mounting blocks 41, and the supporting leg 42 and the torsional spring 44 are both located between the two mounting blocks 41.

[0062] A stop block 45 is fixed between the two mounting blocks 41, and the stop block 45 is located on the side of the supporting leg 42 close to the outer box body 1 in the first direction, and the stop block 45 is used to limit the supporting leg 42 when the supporting leg 42 is reset from the storage state to the support state. Specifically, when the supporting leg 42 is in the support state, the supporting leg 42 and the stop block 45 abut, and the bottom of the supporting leg 42 abuts the horizontal plane. In this embodiment, one end of the torsional spring 44 abuts the bottom wall of the inner box body 2, and the other end abuts the stop block 45.

[0063] In one embodiment, the supporting leg 42 comprises a first structure part 421 arranged to extend in the vertical direction in the support state, and a second structure part 422 extending from the first structure part 421 to the side close to the outer box body 1 in the first direction, and the first structure part 421 and the second structure part 422 are inclinedly transitioned. One end of the first structure part 421 away from the second structure part 422 is fixedly combined with the connecting shaft 43, and the bottom of the second structure part 422 abuts the horizontal plane when the supporting leg 42 is in the support state. The arrangement of the second structure part 422 at the bottom of the supporting leg 42 can increase the contact area between the bottom of the supporting leg 42 and the horizontal plane, and improve the supporting performance of the supporting leg 42 on the inner box body 2.

[0064] In this embodiment, one end of the second structure part 422 away from the first structure part 421 is provided with a roller 46, which is in contact with the horizontal plane when the supporting leg 42 is in the support state, and can rotate with the inner box body 2 as the second direction axis. The arrangement of the roller 46 improves the stability and smoothness of the inner box body 2 when moving in and out, and can reduce the friction between the supporting leg 42 and the horizontal plane, thereby reducing the wear of the supporting leg 42, prolonging the service life of the supporting leg 42, reducing the noise generated by friction, providing a quieter atmosphere for the working environment, and avoiding the stress of the cattle.
