[0031] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly defined and limited, the terms "arranged", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] As Figures 1 to 5 shown, the micro-scale cryopreservation tube of the present invention includes: a tube body 1 and a base 2, and an accommodation space 21 for inserting the tube body 1 is formed on the base 2; a locking assembly 3, the locking assembly 3 includes a clamping structure 31, the clamping structure 31 is arranged in the accommodation space 21, and when the tube body 1 is inserted into the accommodation space 21 to a predetermined position, the clamping structure 31 forms a clamping limit on the tube body 1.

[0033] See Figure 1 , the surface of the tube body 1 is marked with scales, and a cover body is threadedly connected to the top of the tube body 1; an accommodation space 21 is formed on the base 2 from the top surface towards the bottom surface, and the tube body 1 can be placed in the accommodation space 21.

[0034] See Figure 1 、 Figure 2, in the initial state, the locking component 3 is in the unlocked state. When the pipe body 1 is inserted into the accommodating space 21 of the base 2 to a predetermined position, the clamping structure 31 can circumferentially clamp the part of the pipe body 1 inserted into the accommodating space 21, thereby fixing the position of the pipe body 1 and realizing the separate placement of the pipe body 1, which is convenient for the staff to distinguish and take; when the pipe body 1 is taken out of the base 2, it is only necessary to pull the pipe body 1 upward out of the accommodating space 21 of the base 2. It has the characteristics of simple structure and convenient operation. When the pipe body 1 is pulled out of the accommodating space 21 of the base 2, the clamping structure 31 is automatically unlocked to facilitate the next insertion of the pipe body 1.

[0035] In one or more embodiments, the clamping structure 31 includes: a guiding surface 311 formed on the inner wall of the accommodating space 21; a support member 312 that can be lifted and lowered along the axial direction of the accommodating space 21. A sphere 313 that can move toward the center inside the support member 312 is clamped on the support member 312. The bottom of the support member 312 is connected to the base 2 through a first elastic member 314; a first rubber bladder 315 disposed inside the support member 312 and in contact with the sphere 313, and a second rubber bladder 316 disposed on the surface of the accommodating space 21 above the support member 312. Among them, the first rubber bladder 315 and the second rubber bladder 316 are communicated through a conduit.

[0036] See Figures 1 to 5 , in the initial state, under the action of the first elastic member 314, the support member 312 is pushed upward to a stationary position so that the sphere 313 is in contact with both the guiding surface 311 of the accommodating space 21 and the first rubber bladder 315.

[0037] When the pipe body 1 is inserted into the accommodating space 21 of the base 2 and presses down the support member 312 to make the first elastic member 314 in a compressed state, the support member 312 drives the sphere 313 to slide on the guiding surface 311 of the accommodating space 21. The sphere 313 gradually enters the inside of the support member 312 and squeezes the first rubber bladder 315. The gas inside the first rubber bladder 315 enters the second rubber bladder 316 through the conduit, so that the second rubber bladder 316 expands. A plurality of second rubber bladders 316 uniformly arranged on the inner wall of the accommodating space 21 can contact and squeeze the outer wall of the pipe body 1, and then form a fixation of the pipe body 1, realizing that only by inserting the pipe body 1 into a predetermined position in the accommodating space 21 of the base 2, the pipe body 1 can be automatically clamped, forming a limitation on the position of the pipe body 1, with simple structure and convenient operation.

[0038] When the pipe body 1 needs to be taken out, keep the position of the base 2 unchanged and pull out the pipe body 1 upward; at this time, under the action of the first elastic member 314, the first elastic member 314 drives the support member 312 and the sphere 313 to move upward synchronously. At this time, the sphere 313 no longer presses the first rubber bladder 315, and since the first rubber bladder 315 and the second rubber bladder 316 are made of rubber material and have a certain elasticity, the first rubber bladder 315 and the second rubber bladder 316 can gradually return to the initial state, that is, the gas inside the second rubber bladder 316 enters the first rubber bladder 315 through the conduit, the second rubber bladder 316 shrinks, and the first rubber bladder 315 expands; through this setting, the clamping structure 31 can be unlocked, facilitating the next placement of the pipe body 1.

[0039] In one or more embodiments, the locking assembly 3 further includes an unlocking structure 32 disposed inside the base 2. The unlocking structure 32 can selectively unlock the clamping structure 31 to relieve the restriction on the pipe body 1; the unlocking structure 32 includes: a rotating groove 321 opened on the top surface of the base 2; a first magnet 322 disposed in the rotating groove 321 and a second magnet disposed in the second rubber bladder 316; wherein, the first magnet 322 and the second magnet are magnetically attracted to each other, and the first magnet 322 forms a dislocation with the second magnet by means of a second elastic member 323 disposed in the rotating groove 321; a rotating handle 4 connected to the first magnet 322 is disposed at the top end of the base 2.

[0040] See Figure 2 , the rotating handle 4 has an annular structure. The number of the rotating grooves 321 corresponds to the number of the second rubber bladders 316. The cross-sectional shape of the rotating groove 321 is kidney-shaped, and each first magnet 322 disposed in the rotating groove 321 is connected to the rotating handle 4.

[0041] In the initial state, under the action of the second elastic member 323, the first magnet 322 and the second magnet are in a dislocation state; when the pipe body 1 inside the base 2 needs to be unlocked, control the rotating handle 4 to rotate. The rotating handle 4 drives a plurality of first magnets 322 to rotate synchronously. When the first magnet 322 rotates to a position corresponding to the second magnet, the first magnet 322 and the second magnet are magnetically attracted to each other. The second magnet drives the second rubber bladder 316 to shrink to squeeze the gas inside the second rubber bladder 316, so that the gas inside the second rubber bladder 316 enters the first rubber bladder 315 through the conduit. At this time, the second rubber bladder 316 shrinks and the first rubber bladder 315 expands. The outer wall of the pipe body 1 is no longer restricted by the second rubber bladder 316. At the same time, under the action of the first elastic member 314, the support member 312 can move upward, that is, the support member 312 can drive the pipe body 1 to move upward a certain distance. At this time, the entire locking assembly 3 is in an unlocked state, and the pipe body 1 can be taken out of the base 2, which has the characteristics of simple structure and convenient operation.

[0042] In one or more embodiments, the first elastic member 314 and the second elastic member 323 are springs or elastic steel.

[0043] In one or more embodiments, a friction force enlargement portion 41 is formed on the outer circumference of the handle 4. Figure 1 , Figure 3 The friction force enlargement portion 41 is a tooth groove provided on the outer peripheral side of the handle 4. This arrangement makes it easier for the operator to rotate the handle 4.

[0044] In one or more embodiments, an elastic wire is disposed in the first rubber bag 315 and / or the second rubber bag 316. The elastic wire has a certain elasticity and can assist the first rubber bag 315 and the second rubber bag 316 to expand, thereby extending the service life of the first rubber bag 315 and the second rubber bag 316.

[0045] In one or more embodiments, a diameter expansion portion is formed at the bottom of the base 2, or a counterweight is installed at the bottom of the base 2. The enlarged diameter portion and the counterweight are not shown in the accompanying drawings; the enlarged diameter portion is in the shape of a disk or an annular ring; when the enlarged diameter portion is formed at the bottom of the base 2, the cross-sectional shape of the base 2 is roughly "丄"-shaped. This arrangement can ensure the stability of the structure of the base 2 and improve the stability of the tube body 1 placed in the base 2. In addition, the counterweight installed at the bottom of the base 2 can lower the overall center of gravity of the base 2, further improving the stability of the base 2 in placing the tube body 1.

[0046] In one or more embodiments, the sphere 313 is made of hard plastic or hard metal. The hard metal can be iron, aluminum, copper, etc., without limitation.
