DETAILED DESCRIPTION

[0019] In order to further illustrate the technical means and effects taken by the utility model to achieve the predetermined purpose, the specific implementation, structural features and effects of the utility model will be described in detail as follows in combination with the drawings and examples.

[0020] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] In the description of the utility model, it is understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "alignment", "overlap", "bottom", "inner", "outer" and the like is the orientation or positional relationship shown based on the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0022] The terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features; in the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0023] Figure 1 As shown is a kind of stem cell exosome storage device, including box 1, the test tube storage piece 2 of being placed in box 1, the cover 3 of the opening of box 1 is screwed, special is that, a spring pin assembly is through the center of cover 3, the bottom end of the spring pin assembly is connected with a touch pressure plate 6 by connecting column 5;Spring telescopic cylinder 7 is arranged between the bottom plate of box 1 and the bottom of test tube storage piece 2. After test tube storage piece 2 (including test tube) is placed in box 1 in advance, cover cover 3, i.e. lid, then touch pressure plate 6 is pushed down by spring pin assembly through connecting column 5, and is in contact with the top surface of test tube storage piece 2, so that test tube storage piece 2 is clamped, stable between touch pressure plate 6 and the inside bottom plate of box 1, effectively prevent it from shaking. It needs to be explained here that the lid of test tube is rubber material, can play the role of buffering, protection. Of course, the bottom surface of touch pressure plate 6 can be provided with soft pad.

[0024] And spring pin assembly includes Figure 1The pressing tube 4 shown is disposed in the center of the cover 3. A double-headed spring pin (a type of spring pin) is disposed inside the pressing tube 4. The limiting pins 40 of the double-headed spring pin protrude from the two opposite vertical side walls of the pressing tube 4. A push rod 41 is inserted from the top of the pressing tube 4 to push the spring 42 of the double-headed spring pin downward, thereby retracting the limiting pin 40 into the pressing tube 4, thereby creating a gap between it and the through hole on the cover 3, so as to facilitate the entry and exit of the pressing tube 4. That is, when the push rod 41 is pressed down and pushes the spring 42, the limiting pin 40 is dragged by the spring 42 and retracts towards the pressing tube 4, releasing the obstruction between the limiting pin 40 and the top surface of the cover 3. The pressing tube 4 continues to move downward, and then drives the pressing plate 6 to move into the box 1 through the connecting column 5 until it touches the top of the test tube storage component 2. It continues to press down until the spring telescopic cylinder 7 is completely compressed. At this point, the upper and lower clamping of the test tube storage component 2 is completed. Together with the four side walls of the box 1, the test tube storage component 2 is securely fixed, effectively preventing it from shaking and ensuring the safety of the test tube.

[0025] See you later Figure 1 In this embodiment, a spiral return spring 8 is installed on the outer sleeve of the connecting column 5. Its top and bottom ends press against the bottom of the pressing tube 4 and the top of the pressing plate 6, respectively. Firstly, it is used to press the limiting pin 40 tightly against the inner side of the cover 3. Secondly, it is used to push the pressing tube 4 upward, i.e., towards the outside of the cover 3, when it is loosened. Thirdly, it is used to provide elastic pressure to the pressing plate 6, which has good shock absorption.

[0026] To further ensure the safety of the test tubes, this embodiment includes a [missing information - likely a device or feature] on the inner side wall of the housing 1. Figure 1 The vertical groove 9 shown is provided with a vertical slide piece 10 on the corresponding side wall of the test tube storage piece 2, which is inserted into the vertical groove 9 and slides up and down, so as to guide and stabilize it and prevent it from tilting.

[0027] The spring telescopic cylinder 7 provided in the above embodiments is a common type, consisting of a cylinder 11, a support plate 12, and multiple evenly arranged helical springs 13; the two ends of the helical springs 13 are fixedly connected to the cylinder 11 and the support plate 12, respectively. In this embodiment, the inner diameter of the cylinder 11 is larger than the outer diameter of the test tube storage component 2, so that the test tube storage component 2 can be pressed into the cylinder 11 to form a sleeve, further stabilizing the test tube storage component 2.

[0028] Meanwhile, in order to avoid rigid contact and to have a certain degree of elasticity, a silicone ring is provided on the inner side wall of the top of the cylinder 11 in this embodiment, so that when the test tube storage component 2 is pressed into the cylinder 11, there is a gap between them.

[0029] Finally, a plurality of positioning protrusions 14 are arranged on the bottom outer edge of the touch plate 6, and the top outer edge of the test tube storage member 2 is provided with positioning grooves 15 matched with the positioning protrusions 14. The positioning of the touch plate 6 and the test tube storage member 2 can be achieved, so that the contact between them is more closely, which helps to achieve the integrity of the two, and improves the anti-shaking performance of the test tube storage member 2.

[0030] A binding belt can also be arranged on the top surface of the pressing tube 4, so that after the push rod 41 is moved downward to the position, the push rod 41 is positioned by binding the transverse push rod 43 of the push rod 41, avoiding the retraction of the limiting pin 40 caused by accidental touch, causing the pressing tube 4 to be pushed outwards, causing the touch plate 6 to be loose.
