[0002] The liquid nitrogen biocontainer placement device is an auxiliary device specifically designed for the safe placement and operation of liquid nitrogen biocontainers. This device is widely used in fields such as biomedical sample preservation and industrial cryogenic treatment, and is a key auxiliary tool for improving the safety and efficiency of liquid nitrogen operations.

[0003] Chinese patent CN211686286U discloses a liquid nitrogen biological container placement device, comprising a square frame, a container support frame, and a locking member for locking the container support frame. The container support frame is rotatably mounted within the square frame. The locking member has a locked state and an unlocked state. In the locked state, the locking member locks the container support frame; in the unlocked state, the locking member unlocks the container support frame. This liquid nitrogen biological container placement device allows the liquid nitrogen biological container to be placed on the container support frame. When liquid nitrogen needs to be poured, the container support frame is rotated at an appropriate angle, and the liquid nitrogen biological container tilts accordingly, allowing for convenient pouring of liquid nitrogen into a Dewar flask or other suitable container. The operation is convenient and does not easily damage the container.

[0004] The above-mentioned device has the function of preventing damage to the container, but in the actual application of the existing device, it is still difficult to pick up and put down the container, and how to solve the stability problem of the container during the transportation process. Therefore, it is necessary to provide a liquid nitrogen biological container placement device. Utility Model Content

[0005] The purpose of this invention is to provide a liquid nitrogen biological container placement device to solve the problems of difficulty in placing and removing containers in existing devices, as well as the stability of containers during transportation.

[0012] Preferably, the center of the slide rod and the center of the first clamp are on the same straight line, and the inner diameter of the top plate is smaller than the inner diameters of the first clamp and the second clamp.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This liquid nitrogen biological container placement device, by controlling the first handle and the second handle, causes the first clamp and the second clamp to open relative to each other under the action of the outer tube and the inner tube, respectively. After the first clamp and the second clamp are located on both sides of the container, the first handle and the second handle are released so that they are reset under the action of the support spring, and the container can be clamped between the first clamp and the second clamp. The control rod controls the base, and thanks to the shape of the base, the base can lift and support the container, so that the container can be transferred.

[0015] 2) The liquid nitrogen biological container placement device allows the push column to be pulled upwards so that the top plate is higher than the first clamp. At this time, the first handle, the second handle, and the control rod can be controlled to clamp the container. After the container is clamped, the push column is released so that the top plate, supported by the sliding rod, applies pressure to the container, thus fixing the container. When placing the container, the control rod is controlled to move the bottom support out, which in turn moves the container out under the pushing force of the top plate, thus placing the container.

[0022] Example 1

[0023] Combination Figures 1-3 A liquid nitrogen biological container placement device includes a first clamp 1 and a second clamp 2, with a transfer mechanism 3 disposed between the first clamp 1 and the second clamp 2; the transfer mechanism 3 includes an outer tube 301 and an inner tube 302, the outer tube 301 is fixedly installed on the first clamp 1, the inner tube 302 is fixedly installed on the second clamp 2, a first handle 303 is fixedly installed at one end of the outer tube 301, a second handle 304 is fixedly installed at one end of the inner tube 302, a support spring 305 is fixedly installed between the second handle 304 and the first handle 303, a control rod 306 is rotatably installed through the inner tube 302, and a base 307 is fixedly installed at one end of the control rod 306.

[0024] The outer tube 301 is fitted onto the inner tube 302, and the outer tube 301, inner tube 302, and control lever 306 are rotatably connected to each other. The first grip 303 and the second grip 304 are located on the same plane. The first clamp 1 and the first grip 303, and the second clamp 2 and the second grip 304 are respectively located on the same side of the outer tube 301 and the inner tube 302, ensuring that when controlling the first grip 303 and the second grip 304, the first clamp... Seat 1 and clamp 2 swing with handle 303 and handle 304. When pressure is applied to handle 303 and handle 304, clamp 1 and clamp 2 will be opened, thereby clamping the vessel. The base 307 is composed of a stepped platform and has several grooves arranged in parallel on it. When the control lever 306 is rotated, the vessel can be lifted and the liquid nitrogen attached to the base 307 can be filtered out.

[0025] Example 2

[0026] See Figure 4 A booster mechanism 4 is provided on the first grip 303. The booster mechanism 4 includes a limit seat 401. The limit seat 401 is fixedly installed on the first grip 303, and a slide rod 402 is slidably installed through the limit seat 401. A push column 403 is fixedly installed at one end of the slide rod 402. A pressure spring 404 is fixedly installed between the push column 403 and the limit seat 401. A top plate 405 is fixedly installed at the other end of the slide rod 402.

[0027] The limiting seat 401 and the first handle 303 are on the same straight line. The slide rod 402 and the control rod 306 are of the same length. The center of the slide rod 402 and the first clamp 1 are on the same straight line. The inner diameter of the top plate 405 is smaller than the inner diameter of the first clamp 1 and the second clamp 2, so that the slide rod 402 pushes the top plate 405 into the first clamp 1 under the action of the pressure spring 404. When in use, pull the push column 403 upward so that the top plate 405 is higher than the first clamp 1. At this time, the first handle 303, the second handle 304 and the control rod 306 can be controlled to clamp the vessel. After the vessel is clamped, release the push column 403 so that the top plate 405 presses on the vessel under the support of the slide rod 402, thus fixing the vessel. When putting the vessel in, control the control rod 306 to move the base 307 out, and then the vessel moves out under the action of the push of the top plate 405.

[0028] In actual operation, by controlling the first handle 303 and the second handle 304, the first clamp 1 and the second clamp 2 are opened relative to each other under the action of the outer tube 301 and the inner tube 302, respectively. At this time, after the first clamp 1 and the second clamp 2 are located on both sides of the vessel, the first handle 303 and the second handle 304 are released so that they are reset under the action of the support spring 305, and the vessel can be clamped between the first clamp 1 and the second clamp 2. The control rod 306 controls the base 307. Benefiting from the shape of the base 307, the base 307 can lift and support the vessel, so that the vessel can be transferred.

[0029] Pull the push column 403 upward so that the top plate 405 is higher than the first clamp 1. At this time, the first handle 303, the second handle 304 and the control rod 306 can be controlled to clamp the vessel. After the vessel is clamped, release the push column 403 so that the top plate 405, supported by the slide rod 402, applies pressure to the vessel, thus fixing the vessel. When placing the vessel, control the control rod 306 to move the base 307 out, and then the vessel is moved out under the pushing force of the top plate 405, thus placing the vessel.
