[0002] In related technologies, cells can be contained in cryovials and then placed together with the cryovials into a liquid nitrogen tank. However, when removing or placing the cryovials from the liquid nitrogen tank, the cryovials are stored relatively close together, making them difficult to handle with tweezers, and direct handling by hand poses a risk of frostbite. Therefore, there is room for improvement. Utility Model Content

The pipe clamp includes two clamping arms, each clamping arm including a gripping section and a clamping section. The clamping section and the gripping section are bent and connected. The end of the gripping section away from the clamping section is configured as a fixed end. The fixed ends of the two clamping arms are connected and the clamping sections are spaced apart and distributed opposite to each other. The gripping sections of the two clamping arms are both configured to be elastically deformable, and the clamping sections of the two clamping arms can elastically move closer to or further away from each other. Each clamping section forms a pipe wall clamping groove. The two pipe wall clamping grooves are open to each other and are used to clamp the outer peripheral wall of the tubular component together.
[0005] According to the embodiment of the present utility model, the tube clamp can clamp tubular parts by setting a tube wall clamping groove.

[0009] According to some embodiments of the present invention, the outer side of the gripping section of the pipe clamp is formed with a gripping groove, which is used to fit snugly against the hand.
[0010] According to some embodiments of the present invention, the inner wall of the pipe clamping groove is provided with an anti-slip protrusion.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] The following is for reference. Figures 1-6The tube clamp 100 according to an embodiment of the present utility model is described. The tube clamp 100 can directly clamp the cryopreservation tube, and during the clamping process, the tube clamp 100 can stably contact the cryopreservation tube to ensure the reliability of clamping the cryopreservation tube, and can avoid the risk of frostbite to the hands during the handling process, thereby improving the handling safety.
[0032] like Figures 1-6 As shown, a pipe clamp 100 according to an embodiment of the present invention is used to clamp a tubular component, and the pipe clamp 100 includes two clamping arms 1.
[0033] Each clamping arm 1 includes a gripping section 11 and a clamping section 12. The clamping section 12 is bent and connected to the gripping section 11, that is, the gripping section 11 and the clamping section 12 extend in different directions and are bent and connected at a certain angle. The gripping section 11 is used for the operator's hand to grip and operate the pipe clamp 100, while the clamping section 12 is used to clamp the tubular parts.
[0034] In this design, the end of the gripping section 11 facing away from the clamping section 12 is configured as a fixed end 13, and at least a portion of the clamping section 12 is configured as a clamping end 14, such that the entire clamping section 12 is configured as a clamping end 14 for clamping tubular components. That is, each clamping arm 1 has a fixed end 13 and a clamping end 14. The fixed ends 13 of the two clamping arms 1 are connected, and the clamping ends 14 are spaced apart and distributed opposite each other. The gripping sections 11 of both clamping arms 1 are configured to be elastically deformable, allowing the clamping sections 12 of the two clamping arms 1 to elastically move closer to or further away from each other. In other words, the two clamping arms 1 are connected to form a whole, and a clamping space is formed between the clamping sections 12 of the two clamping arms 1. Thus, when clamping a tubular component using the tube clamp 100, the clamping sections 12 of the two clamping arms 1 can extend to both sides of the tubular component, and the two clamping sections 12 can clamp both sides of the tubular component respectively.
[0035] It is understood that the fixed ends 13 of the two clamping arms 1 are fixedly connected at a certain angle so that most of the two clamping arms 1 are spaced apart, and most of the clamping arms 1 can elastically deform relative to their fixed ends 13. Thus, when the operator operates the pipe clamp 100, he can hold the clamping arms 1 and apply force to bring the clamping sections 12 of the two clamping arms 1 closer to each other. After clamping, the two clamping arms 1 can return to the clamping state under the action of elastic restoring force, which is convenient for clamping again.
[0036] like Figures 1-6As shown, the right end of the gripping section 11, i.e. the end away from the clamping section 12, can be constructed as a fixed end 13 so that this end can be fixedly connected to the fixed end 13 of another clamping arm 1. At the same time, the clamping section 12 can be constructed as a clamping end 14 so that the clamping section 12 can clamp tubular parts of different lengths. That is, the clamping section 12 can make abutting contact with the outer peripheral wall of the tubular part at different positions in the length direction, thereby increasing the contact area and ensuring the stability and reliability of clamping.
[0037] Therefore, by constructing the clamping arm 1 as including two parts extending in different directions, the clamping section 12 can extend to the outside of the tubular part from different directions to clamp it when the operator performs a gripping operation on the gripping section 11, reducing the restriction of the clamping space on the operator's hand position and helping to reduce the difficulty of operation.
[0038] It should be noted that the tube clamp 100 can be used in biological experiments, meaning the tubular component can be a cryovial, allowing the tube clamp 100 to hold the cryovial. Alternatively, the tube clamp 100 can also be used in other scenarios, such as when the tubular component is at a high temperature. Furthermore, while this invention uses a tubular component as an example of a cryovial, its application is not limited to cryovial scenarios.
[0039] Each clamping segment 12 has a tube wall clamping groove 15. Two tube wall clamping grooves 15 are arranged open to each other and are used to clamp the outer peripheral wall of the tubular component. In other words, the clamping arm 1 in this invention forms a clamping engagement with the outer peripheral wall of the tubular component through the tube wall clamping groove 15. This eliminates the need for direct hand handling of the cryopreservation tube and avoids the risk of it falling off when clamped with the tip of traditional tweezers. In other words, by clamping the outer peripheral wall of the tubular component through the tube wall clamping groove 15, the clamping segment 12 can adapt to the outer peripheral wall of the tubular component, providing a large contact area between the tube clamp 100 and the tubular component. Furthermore, the inner wall of the tube wall clamping groove 15 can limit the movement of the tubular component, preventing tilting or detachment during clamping and improving the reliability of the tubular component clamping.
[0040] Therefore, when the cryopreservation tube is held by the tube clamp 100, even if the cryopreservation tube is placed in a liquid nitrogen tank (-176°C), the operator can still hold it by the tube clamp 100. It can also be used to hold the cryopreservation tube when performing water bath cell revival, thus avoiding direct contact between the operator's hands and the cryopreservation tube and protecting the operator's safety.
[0041] According to the embodiment of the present utility model, the tube clamp 100 can clamp the tubular part by setting the tube wall clamping groove 15. It can be applied to the working scene of cryopreservation tubes, which can avoid the operator's hands from directly contacting the cryopreservation tubes, prevent frostbite, and ensure the stability of clamping the tubular part, preventing the cryopreservation tubes from falling during the clamping process, making it more convenient to use.
[0042] In some embodiments, the pipe wall clamping groove 15 extends through the clamping section 12 along the extending direction of the gripping section 11, and at least a portion of the pipe wall clamping groove 15 extends into the gripping section 11 along the extending direction of the gripping section 11, such as... Figures 1-6 As shown, the lower end of the pipe wall clamping groove 15 extends to the lower end of the clamping section 12. At the same time, the upper end of the pipe wall clamping groove 15 extends upward into the gripping section 11, and the extension direction of the portion of the pipe wall clamping groove 15 extending into the gripping section 11 is the same as the extension direction of the gripping section 11. This increases the extension length of the pipe wall clamping groove 15, thereby increasing the mating length between the pipe wall clamping groove 15 and the pipe when clamping the tubular part, which in turn helps to increase the clamping stability.
[0043] The pipe wall clamping groove 15 extends to the end of the clamping section 12 opposite to the gripping section 11, so that the pipe wall clamping groove 15 forms a clearance opening. In this way, when clamping the tubular part, the two clamping sections 12 can extend to the outside of the tubular part from their respective clearance openings. That is, the clearance opening can avoid the tubular part, so that the tubular part can quickly enter between the two clamping sections 12, thereby facilitating the rapid clamping of the tubular part and improving the clamping efficiency.
[0044] In some embodiments, the angle between the extending direction of the gripping section 11 and the extending direction of the clamping section 12 is A, and satisfies: 60°≤A≤120°. For example, the angle between the extending direction of the gripping section 11 and the extending direction of the clamping section 12 can be set to 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, or 120°, or it can be set to other angle values between 60° and 120°. All of these can achieve the bending connection between the gripping section 11 and the clamping section 12. The setting method is flexible and selectable, which is conducive to meeting the clamping requirements under different spatial positions and improving the applicability of the pipe clamp 100.
[0045] And / or, in some embodiments, the extension length of the gripping segment 11 is greater than the extension length of the clamping segment 12, such as setting the extension length of the gripping segment 11 to be 2 times, 3 times, or other length relationships of the extension length of the clamping segment 12, thereby increasing the gripping length of the gripping segment 11 for the operator, which is conducive to the operator's stable gripping of the gripping segment 11 and ensuring the reliability of the clamping process.
[0046] In some embodiments, a gripping groove 111 is formed on the outer surface of the gripping section 11. The gripping groove 111 is used to fit snugly against the hand. That is, the gripping groove 111 can be constructed to match the groove shape of the operator's hand. In this way, when the operator grips the gripping section 11, the hand and the gripping groove 111 can form a deeper fit, which helps to increase the friction between the hand and the gripping section 11 and enhance grip stability.
[0047] Specifically, such as Figures 1-6 As shown, the gripping groove 111 can extend along the length of the gripping section 11, and the depth of the gripping groove 111 gradually increases near the fixed section of the gripping section 11, and as... Figure 3 As shown, a recessed line is formed in the gripping groove 111, and the lowest position of the recessed line is the deepest position of the gripping groove 111. This position can be deeply fitted with the inner surface of the operator's hand, thereby increasing the gripping depth.
[0048] In some embodiments, an anti-slip protrusion 151 is formed on the inner wall of the pipe wall clamping groove 15. The anti-slip protrusion 151 protrudes from the inner wall of the pipe wall clamping groove 15 and is used to press against the outer peripheral wall of the tubular component. That is, when the tubular component is clamped by the pipe clamp 100, the inner wall of the pipe wall clamping groove 15 is in contact with the outer peripheral wall of the tubular component through the anti-slip protrusion 151. This allows the force on the clamping section 12 to be concentrated at the anti-slip protrusion 151, which forms a tight contact with the outer peripheral wall of the tubular component, creating a force concentration point. This prevents the tubular component from slipping out of the pipe wall clamping groove 15 during the clamping process.
[0049] In a further embodiment, the anti-slip protrusion 151 is constructed as a long strip and extends circumferentially along the pipe wall clamping groove 15. That is, the anti-slip protrusion 151 can be constructed as an anti-slip rib or anti-slip stripe so that the anti-slip protrusion 151 can make line contact with the outer peripheral wall of the tubular part, thereby increasing the friction.
[0050] The anti-slip protrusion 151 can extend in the circumferential direction of the pipe wall clamping groove 15, or it can be configured to form a small angle with the circumferential direction of the pipe wall clamping groove 15. In this way, the clamping and anti-slip function of the tubular part can be achieved.
[0051] like Figures 4-6 As shown, the anti-slip protrusion 151 extends circumferentially into the pipe wall clamping groove 15, and the extension length of the anti-slip protrusion 151 can be more than half of the circumferential length of the inner wall of the pipe wall clamping groove 15. This facilitates increasing the mating length between the anti-slip protrusion 151 and the outer peripheral wall of the tubular component, thereby increasing grip stability. Figure 6As shown, the end of the anti-slip protrusion 151 extends to the edge of the pipe wall clamping groove 15, and a smooth slope can be formed at the end of the anti-slip protrusion 151 to avoid the end of the anti-slip protrusion 151 being too sharp and causing damage to the outer peripheral wall of the tubular part.
[0052] Alternatively, in some embodiments, multiple anti-slip protrusions 151 are provided, and the multiple anti-slip protrusions 151 are spaced apart along the extension direction of the pipe wall clamping groove 15. Thus, two, three or more anti-slip protrusions 151 can be provided, so that multiple anti-slip protrusions 151 can simultaneously clamp the outer peripheral wall of the tubular component, thereby increasing the clamping force and enhancing the clamping effect.
[0053] The multiple anti-slip protrusions 151 can be spaced in parallel, and the distance between each anti-slip protrusion 151 is relatively uniform, so that the clamping force between the clamping section 12 and the tubular part at various positions in the clamping area is relatively uniform, avoiding excessive clamping force in some positions and gaps in some positions, which helps to improve the clamping safety of the tubular part.
[0054] Specifically, such as Figures 4-6 As shown, the anti-slip protrusion 151 is elongated, and there are four anti-slip protrusions 151. The four anti-slip protrusions 151 are distributed parallel to each other in the length direction of the clamping section 12, which can realize the joint clamping at multiple positions.
[0055] In some embodiments, the anti-slip protrusions 151 in the two pipe wall clamping grooves 15 are symmetrically distributed. As a result, the clamping forces generated by the anti-slip protrusions 151 in the two pipe wall clamping grooves 15 on the tubular part are opposite to each other. Thus, the two pipe wall clamping grooves 15 can achieve opposite clamping of the tubular part, that is, the clamping forces acting on both sides of the tubular part are more balanced. In this way, the pipe clamp 100 clamps the tubular part more stably.
[0056] In actual design, the anti-slip protrusions 151 of the two pipe wall clamping grooves 15 can be set to four, and the four anti-slip protrusions 151 are arranged one-to-one in the opposite direction of the two clamping sections 12, so that the clamping force formed by the two clamping sections 12 at the anti-slip protrusions 151 is more balanced and stable.
[0057] And / or, in other embodiments, the two pipe wall clamping grooves 15 are adapted to be joined together to form a cylindrical groove; in other words, both pipe wall clamping grooves 15 can be constructed as semi-circular grooves. Thus, when clamping the tubular component using the two pipe wall clamping grooves 15, the pipe wall clamping grooves 15 can make contact with the tubular component over a larger area, thereby facilitating stable clamping of the tubular component.
[0058] In some embodiments, the pipe wall clamping grooves 15 of the two clamping arms 1 are symmetrically distributed, thereby the clamping force generated by the two pipe wall clamping grooves 15 on the tubular part is more balanced, that is, the clamping force acting on both sides of the tubular part is more balanced, so that the pipe clamp 100 clamps the tubular part more stably.
[0059] Meanwhile, when processing the two clamping arms 1, the two clamping arms 1 can be formed using the same mold or method, which helps to reduce processing difficulty and production costs.
