[0025] This embodiment provides a biological sample freezing device. Figure 2 : is a structural diagram of the cover opening assembly (including the gas spring 300, the guide rail 400, the mounting member 500, the mounting block 600 and the first connecting rod 700, etc.) of the biological sample freezing device in this embodiment. Figure 3 yes Figure 2 The structure shown is a schematic diagram after some components (rotating column 530, second connecting rod 540 and bearing 550) are hidden. Figure 4 yes Figure 3 Another perspective of the picture.

[0026] The biological sample freezing device includes a cavity, a gas spring 300, at least one guide rail 400 and a cover. The cavity defines a accommodating chamber with an opening, the opening being located at one end of the accommodating chamber in a first direction, and the accommodating chamber is used to freeze biological samples. The gas spring 300 is installed in the cavity, and the piston 310 of the gas spring 300 extends along the first direction. The guide rail 400 is fixed to the cavity, the guide rail 400 extends along the first direction, and the guide rail 400 is slidably provided with a mounting member 500, the mounting member 500 is fixedly connected to the piston 310, and the mounting member 500 moves along the first direction on the guide rail 400 under the drive of the piston 310. The cover is connected to the mounting member 500, and the cover also moves in the same direction as the mounting member 500 moves in the first direction.

[0027] In some embodiments, the cavity includes a liquid nitrogen tank, and in other embodiments, the cavity may include a box, etc. In some embodiments, the first direction includes a vertical direction, and in other embodiments, the first direction may include a front-to-back direction, a lateral direction, etc. For example, the cavity is a liquid nitrogen tank, and the opening is at the top of the accommodating cavity. A freezing rack may be provided in the accommodating cavity, and the freezing rack defines a rack cavity, and the rack cavity is used to place a freezing box, and the freezing box is used to store biological samples in the form of freezing tubes or freezing bags, and liquid nitrogen is provided in the accommodating cavity, and the liquid nitrogen is used to store biological samples by cold. In other embodiments, low-temperature storage of biological samples can also be achieved by a compression refrigeration system or other refrigeration systems.

[0028] The gas spring 300 is an industrial accessory that provides support, cushioning, braking, height adjustment, and angle adjustment. It consists of several components: a pressure cylinder, a piston rod, a piston 310, a sealing guide sleeve, a filler (an inert gas or an oil-gas mixture), internal and external control elements (referred to as the controllable gas spring 300), and joints. The principle is to fill a sealed pressure cylinder with an inert gas or oil-gas mixture, raising the pressure within the chamber to several or even dozens of times higher than atmospheric pressure. The piston 310's rod moves by utilizing the pressure differential created by the smaller cross-sectional area of ​​the piston rod 310. Due to this fundamental difference in principle, the gas spring 300 offers significant advantages over conventional springs: relatively slow speed, minimal dynamic force variation (typically within a ratio of 1:1.2), and ease of control. Since the gas spring 300 itself is well known and readily implemented by those skilled in the art, it will not be further described here.

[0029] The biological sample freezing device provided in this embodiment uses a gas spring 300 to achieve translational opening of the cover, thereby eliminating the need to cut an inclined surface on the cover body, thereby ensuring the integrity of the cover body and thus ensuring the heat preservation effect of the cover body. It also has a guide rail 400 to guide the movement of the cover body and ensure smooth movement.

[0030] In some embodiments, the cavity is fixed with a mounting block 600, the mounting block 600 is mounted with the gas spring 300, and the mounting block 600 is fixed with the at least one guide rail 400. Thus, the installation of the gas spring 300 and the guide rail 400 is facilitated.

[0031] In some embodiments, one end of the mounting member 500 is connected to the cover, and the other end of the mounting member 500 is connected to the guide rail 400. A hole 510 is formed in the middle of the mounting member 500 for the gas spring 300 to pass through. This facilitates protection of the gas spring 300 and avoids an excessively long connection distance between the gas spring 300 and the mounting member 500, thereby ensuring the stability of the overall structure.

[0032] In some embodiments, the at least one guide rail 400 includes a first guide rail 410 and a second guide rail 420 that are disposed opposite to each other. This further ensures the accuracy of the guidance, thereby improving the stability of the movement.

[0033] In some embodiments, the mounting member 500 and the piston 310 are fixedly connected via a first connecting rod 700 extending along the first direction. The mounting member 500 and the piston 310 may not be arranged along the first direction, thereby improving space utilization.

[0034] In some embodiments, the mounting member 500 is fixedly connected to the first connecting rod 700 by bolts, thereby improving the stability of the connection.

[0035] In some embodiments, the end of the mounting member 500 away from the guide rail 400 defines a slot 520, and a rotating post 530 is rotatably disposed within the slot 520. The rotating post 530 can rotate along an axis parallel to the first direction. The rotating post 530 is fixedly connected to a second connecting rod 540, which is fixedly connected to the cover. Thus, when opening the cover, the cover can first be translated along the first direction and then rotated to offset the position of the opening, thereby facilitating operation of the opening.

[0036] In some embodiments, a bearing 550 is disposed in the slot 520 to achieve a rotational connection between the mounting member 500 and the rotating column 530. The bearing 550 can reduce friction.

[0037] In some embodiments, a limit ring is provided at the slot 520 to limit the rotation angle of the rotating column 530 , thereby preventing the rotation angle from being too large and interfering with surrounding objects.

[0038] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.

[0039] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. The protection scope of the present application shall be based on the protection scope of the claims.
