[0031] The utility model provides a clamping claw assembly and a cover opening device, which are designed to be rotatably connected to the first clamping body through a second clamping body. When grasping, the second clamping body can automatically adjust its own angle according to the test tube it touches, so that the second clamping body and the angle of the test tube are adapted to ensure that the test tube can be effectively grasped at different angles, so that the second clamping body can fit tightly with the test tube, so as to achieve the purpose of clamping the test tube.

[0032] See also Figures 1 to 7 In one embodiment of the present invention, the clamping jaw assembly 10 includes:

[0033] At least two oppositely disposed clamping jaws 1, each of the clamping jaws 1 comprising a first clamping body 11 and a second clamping body 12, wherein the second clamping body 12 is movably connected to one end of the first clamping body 11, and the second clamping body 12 is used to clamp the test tube 2; and

[0034] A driving member is used to drive the first clamping bodies 11 to drive the two first clamping bodies 11 to move closer to or away from each other.

[0035] In this embodiment, in order to facilitate the gripping of the test tube 2 by the clamping assembly 10, the clamping assembly 10 includes at least two relatively arranged clamping jaws 1. It should be noted that the number of clamping jaws 1 can be two, three, four or more than four. When the number of clamping jaws 1 is an even number, every two clamping jaws 1 are symmetrically arranged. Increasing the number of clamping jaws 1 can increase the relative stability of the clamping to ensure the uniformity of the clamping force and prevent the test tube 2 from falling off during the subsequent clamping process. In addition, the clamping assembly 10 also includes a driving member, which is driven and connected to the clamping assembly 10 to drive the clamping assembly 10 to move so that the two clamping jaws 10 move closer to or away from each other, and when approaching the test tube 2, the clamping jaw assembly 10 opens and clamps the test tube 2. It should be noted that the driving member is a prior art and can be a common motor, a gear rack motion, or other driving source, which is not limited in this application.

[0036] For details, please refer to Figures 1 to 3 Each clamp assembly 10 includes a first clamp 11 and a second clamp 12, wherein the second clamp 12 is movably connected to one end of the first clamp 11, and the driving member is drivably connected to the first clamp 11 on the side away from the second clamp 12. The second clamp 12 is used to clamp the test tube 2, and then, under the drive of the driving member, the two oppositely arranged first clamps 11 are moved closer to or away from each other to grab or put down the test tube 2. Specifically, the second clamp 12 can be rotatably connected to the first clamp 11, and then when grasping, the second clamp 12 can adjust its own angle according to the test tube 2 touched, so that the second clamp 12 and the angle of the test tube 2 can adapt to each other, ensuring that the test tube 2 can be effectively grasped at different angles, so that the second clamp 12 can fit tightly with the test tube 2, so as to achieve the purpose of clamping the test tube 2.

[0037] It should be further explained that the first clamping body 11 and the second clamping body 12 are both integrally formed structures to ensure structural strength and stability.

[0038] For optional embodiments, see Figures 1 to 3 The clamping jaw assembly 10 also includes a rotating member 13, which is installed at one end of the second clamping body 12. The rotating member 13 can be rotatably installed on the end of the first clamping body 11 away from the driving member at both ends of the second clamping body 12. By setting the rotating member 13, it is ensured that the second clamping body 12 can be rotatably set relative to the first clamping body 11, so that when grasping, the second clamping body 12 can adjust its own angle according to the angle of the test tube 2 touched, and then fit tightly with the test tube 2 to achieve the purpose of clamping the test tube 2.

[0039] In this embodiment, in order to facilitate the rotatable connection between the first clamp 11 and the second clamp 12, the clamp assembly 10 further includes a rotating member 13, which is mounted on one end of the second clamp 12. The rotating member 13 is rotatably mounted on the end of the first clamp 11 away from the driving member after passing through both ends of the second clamp 12. It should be noted that the rotating member 13 and the second clamp 12 are fixedly connected, and the rotating member 13 and the first clamp 11 are rotatably connected. Therefore, when the second clamp 12 touches the test tube 2, the rotating member 13 rotates adaptively, thereby driving the second clamp 12 to rotate relative to the first clamp 11, so as to achieve a close fit between the second clamp 12 and the test tube 2, thereby achieving effective gripping of the test tube 2, so as to achieve the purpose of clamping the test tube 2. Of course, the rotating member 13 can also be fixedly connected to the first clamp, and the rotating member 13 and the second clamp 12 can be rotatably connected, so that when the second clamp 12 touches the test tube 2, the second clamp 12 rotates adaptively, so that the second clamp 12 rotates relative to the first clamp 11 and the rotating member 13 to achieve a close fit with the test tube 2, thereby achieving effective gripping of the test tube 2.

[0040] For optional embodiments, see Figures 1 to 3 A first connecting portion 111 is provided at one end of the first clamp 11, and the second clamp 12 includes a clamping body 121 and a second connecting portion 122. The second connecting portion 122 is provided on one side of the clamping body 121, and the second connecting portion 122 is inserted into the first connecting portion 111. The rotating member 13 is installed on the second connecting portion 122, and the rotating member 13 can be rotatably connected to the first connecting portion 111 at both ends passing through the second connecting portion 122.

[0041] In this embodiment, to facilitate the connection between the first clamp 11 and the second clamp 12, a first connecting portion 111 is provided at one end of the first clamp 11. It should be noted that the first connecting portion 111 is provided at the end of the first clamp 11 away from the driving member. The second clamp 12 includes a clamping body 121 and a second connecting portion 122. The second connecting portion 122 is provided on one side of the clamping body 121 and is inserted into the first connecting portion 111. At the same time, a rotating member 13 is mounted on the second connecting portion 122, and the rotating member 13 can be rotatably mounted on the first connecting portion 111 at both ends that pass through the second connecting portion 122, thereby achieving the connection between the first clamp 11 and the second clamp 12 and ensuring the stability of the connection between the first clamp 11 and the second clamp 12, so that the second clamp 12 can stably clamp the test tube 2. It should be noted that through holes are provided on the first connecting portion 111 and the second connecting portion 122 for the rotating member 13 to pass through. It should be further noted that the rotating member 13 is a rotating shaft.

[0042] Specifically, in order to enable the rotating member to stably connect the second clamp to the first clamp, a locking groove is provided on the outer peripheral wall of the rotating member. At the same time, the clamp assembly also includes a locking member 3, which passes through the second clamp 12 and is inserted into the locking groove 131, thereby effectively preventing the rotating member from detaching from the first clamp and the second clamp, thereby ensuring the connection stability between the first clamp 11 and the second clamp 12, so that the second clamp 12 can stably clamp the test tube 2. It should be noted that a through hole for the locking member 3 to pass through is provided in the second connecting portion. At the same time, it should be further noted that the locking member can be a jackscrew or a screw.

[0043] For optional embodiments, see Figure 3 The first connecting portion 111 is a positioning groove, and the second connecting portion 122 is a positioning protrusion, and the positioning protrusion is inserted into the positioning groove.

[0044] In this embodiment, in order to ensure the connection stability between the first clamp 11 and the second clamp 12, the first connecting portion 111 is a positioning groove, and the second connecting portion 122 is a positioning protrusion. When the first clamp 11 and the second clamp 12 are connected, the positioning protrusion is inserted into the positioning groove, and the two are further connected by the rotating member 13, so that the second clamp 12 can not only clamp the test tube 2, but also effectively grasp the test tube 2 at different angles, so that the second clamp 12 can fit tightly with the test tube 2 to achieve the purpose of clamping the test tube 2. It should be noted that the positioning protrusion is elongated and the positioning groove is U-shaped. Such a configuration allows the positioning protrusion to fit into the positioning groove. Of course, the positioning protrusion and the positioning groove can also be other shapes, which are not limited here.

[0045] For optional embodiments, see Figures 1 to 3 The clamping jaw assembly 10 also includes an elastic member, and a plurality of the elastic members are provided. The plurality of elastic members are spaced between the first connecting portion 111 and the second connecting portion 122. By providing the elastic member, after completing the grasping, the second clamping body 12 can be pulled back to its initial position before grasping, so as to facilitate the next clamping of the second clamping body 12.

[0046] In this embodiment, in order to facilitate the second clamp 12 to restore its initial position for grasping the test tube 2, the clamp assembly 10 also includes an elastic member, which is arranged between the first connecting portion 111 and the second connecting portion 122. When the spring is in a free state, the first clamp 11 and the second clamp 12 are in their initial positions, and the second clamp 12 does not rotate at this time. When the two second clamps 12 approach each other under the action of the driving member and rotate relative to the first clamp 11 under the drive of the rotating member 13, the elastic member is stretched to deform. When the second clamp 12 releases the test tube 2, the elastic member pulls the second clamp 12 back to its initial position before grasping, so that the second clamp 12 can perform the next clamping. It should be noted that the elastic member is a spring, and of course it can also be other elastic components, which are not limited here.

[0047] Specifically, there are multiple elastic members, for example, two, three or more. By providing multiple elastic members, the second clamping body 12 can be smoothly pulled back to the position before grasping.

[0048] For optional embodiments, see Figures 1 to 3 One end of part of the elastic member is connected to the side of the first connecting portion 111 facing the clamping body 121, and the other end of part of the elastic member is connected to the side of the clamping body 121 facing the second connecting portion 122. Specifically, one end of the elastic member is connected to the bottom wall of the positioning groove, and the other end of the elastic member is connected to the side of the positioning protrusion facing the bottom wall of the positioning groove.

[0049] In this embodiment, a plurality of elastic members are provided, and one end of some of the elastic members is connected to the side of the first connecting portion 111 facing the clamping body 121, and the other end of the elastic member is connected to the side of the clamping body 121 facing the second connecting portion 122; one end of another portion of the elastic member can be connected to the bottom wall of the positioning groove, and the other end of the elastic member is connected to the side of the positioning protrusion facing the bottom wall of the positioning groove, so that after the second clamp 12 releases the test tube 2, with the assistance of multiple elastic members, the second clamp 12 can be smoothly and stably pulled back to the position before grasping.

[0050] For optional embodiments, see Figure 2 A clamping groove 1211 is provided on one side of the clamping body 121, and the clamping groove 1211 is used to clamp the test tube 2, making the clamping more stable and effective.

[0051] For optional embodiments, see Figure 2The inner side surface of the clamping groove 1211 is serrated, which can effectively increase the contact area between the clamping body 121 and the test tube 2, thereby facilitating the clamping body 121 to clamp the test tube 2, preventing slipping during the clamping of the test tube 2 or the centrifuge cup, and making the clamping more stable and effective.

[0052] For optional embodiments, see Figure 4 The first clamp 11 is provided with a boss 123 on a side away from the first connecting portion 111. By providing the boss 123, the longitudinal position of the first clamp 11 and the second clamp 12 for grasping the test tube 2 is controlled, thereby facilitating subsequent operations such as placing the tube.

[0053] In this embodiment, the first clamp 11 is provided with a boss 123 on the side away from the first connecting portion 111. It should be noted that the boss 123 protrudes a certain width in the direction away from the first clamp 11 to prevent the first clamp 11 and the second clamp 12 from clamping the test tube 2 too low, which would make subsequent tube placement operations inconvenient.

[0054] The present invention also proposes a cover opening device, which includes a clamping jaw assembly 10. The specific structure of the clamping jaw assembly 10 refers to the above embodiment. Since the present cover opening device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0055] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
