Abstract
Description
Technical Field
[0001] This utility model relates to the field of oscillation device technology, and in particular to an oscillation device for cell preservation solution with a fixed structure. Background Technology
[0002] A shaking device for cell preservation solutions is a crucial piece of equipment in the laboratory used to mix cell preservation solutions with cell samples, ensuring the viability and stability of cells during preservation or transportation. During the shaking process, the cell preservation solution can easily generate foam and create pressure within the test tube, potentially causing the stopper to pop open and spilling the cell preservation solution.
[0003] Application No. 202323271191.9 discloses a shaker for cell preservation solution, including a housing and a top plate. A storage assembly is installed inside the housing, comprising a cannula and a ball sleeve. A drive assembly is installed on the housing, comprising a motor and a crankshaft. A connecting assembly is installed on the cannula, comprising a clamping sleeve and a connecting rod. A pushing assembly is installed inside both the clamping sleeve and the ball sleeve, comprising an electromagnet and a spring. This shaker for cell preservation solution can adapt to the shaking operation of test tubes of different diameters, avoiding damage to the test tubes, ensuring test tube safety, and improving the adaptability of the equipment. The pressure rod is clamped to the top of the test tube stopper by a spring to prevent the stopper from falling off. When the air pressure of the cell preservation solution rises due to shaking, the test tube stopper pushes the pressure rod upward, stopping the shaking operation and preventing the cell preservation solution from spilling.
[0004] While the aforementioned shaker can prevent the test tube stopper from falling off, it requires stopping the shaking operation and lacks the function of actively reducing the pressure inside the test tube. Summary of the Invention
[0005] In view of this, the purpose of this utility model is to propose a shaking device for cell preservation solution with a fixed structure, so as to solve the problem that although the current shaking cap can prevent the test tube stopper from falling off, it is necessary to stop the shaking operation and lacks the function of actively depressurizing the test tube.
[0006] To achieve the above objectives, this utility model provides a cell preservation solution shaking device with a fixed structure, including a base frame, and further comprising: two first supports disposed on the top of the base frame, a swing box rotatably disposed between the two first supports, multiple fixing mechanisms disposed in the swing box for fixing test tubes, a first driving mechanism for driving the swing box to swing under its own gravity, clamping and collision mechanisms disposed on both sides of the swing box, and a plugging mechanism disposed above the swing box, wherein: The plug-removing mechanism includes a top frame, an electric cylinder vertically mounted on the top frame, a mounting plate mounted at the end of the telescopic rod of the electric cylinder, and multiple electromagnets mounted at the bottom of the mounting plate. Each electromagnet corresponds to a test tube plug on a test tube in the fixing mechanism. A magnetic component is fixedly mounted on the top of the test tube plug. The attraction force between the magnetic component and the electromagnet is greater than the friction force between the test tube plug and the sieve tube. When the swing box swings, the clamping and collision mechanism gradually approaches the swing box. The swing box collides with the clamping and collision mechanism to generate vibration until the swing box is clamped tightly. The bottom of the swing box is in a straight position parallel to the horizontal plane. At this time, the plug-pulling mechanism starts to work.
[0007] Optionally, the first drive mechanism includes a first motor mounted on the base frame, a half gear fixedly mounted on the rotating shaft of the first motor, and a spur gear capable of meshing with the half gear, the spur gear being fixedly mounted at one end of the swing box.
[0008] Optionally, the clamping and collision mechanism includes a second bracket disposed on both sides of the swing box, a bidirectional lead screw rotatably disposed between the two second brackets, a clamping and collision plate threadedly connected to both sides of the bidirectional lead screw, a slide rod disposed between the two second brackets and sliding through the clamping and collision plate, and a drive unit that drives the lead screw to rotate.
[0009] The second motor on the base frame drives the bidirectional lead screw to rotate via a coupling. Utilizing the opposing spiral threads on both sides of the lead screw, the two clamping collision plates threaded onto the lead screw move synchronously in opposite directions or in a straight line under the guidance and constraint of the slide rod. When the motor rotates forward, the clamping collision plates on both sides rapidly approach each other along the lead screw axis. During this approach, the clamping plates collide with the swinging box, thereby further oscillating the test tube and ultimately clamping and fixing the swinging box, facilitating subsequent plug removal. When the motor rotates in reverse, the clamping collision plates separate in the opposite direction to release the swinging box. Throughout the process, the parallel layout of the slide rod and the bidirectional lead screw ensures smooth movement, while the precise control of the motor speed, direction, and torque enables dynamic adjustment of the clamping position, force, and collision parameters, ultimately achieving integrated and high-precision coordinated control of the clamping and collision functions.
[0010] Optionally, the drive unit is a second motor mounted on the base frame, and the second motor is connected to one end of the lead screw via a coupling.
[0011] Optionally, a first elastic pad is provided on each of the two opposing surfaces of the two clamping collision plates.
[0012] Optionally, the fixing mechanism includes a storage slot disposed on the swing box, elastic telescopic members symmetrically disposed in the storage slot, and an arc-shaped clamping plate disposed on one side of the elastic telescopic members.
[0013] Optionally, the tops of the two arc-shaped clamping plates extend outward to form a flared opening.
[0014] Optionally, a second elastic pad is provided at the bottom of the storage slot.
[0015] The test tube containing cell preservation solution is fixed in the swing box by a fixing mechanism. Then, the first drive mechanism drives the swing box to swing at a certain angle. After that, the connection with the swing box is released. At this time, the swing box swings back and forth under the action of gravity, which initially agitates the cell preservation solution. At the same time, as the swing box swings, the clamping collision mechanism gradually approaches the swing box. The swing box collides with the clamping collision mechanism to generate further oscillation and enhance the oscillation effect until the swing box is clamped tightly and the bottom of the swing box is in a horizontal position. At this time, the stopper removal mechanism starts to work. The electric cylinder extends and drives the electromagnet to descend so that the electromagnet contacts the magnetic component. Then the electromagnet is energized and attracts the magnetic component. Then the electric cylinder shortens and pulls the test tube stopper upward a certain distance, so that the air pressure in the test tube is discharged outward. Then the test tube stopper is put back on, the electromagnet is de-energized, the cylinder returns to the initial position, and then the cycle is repeated until the operation is completed.
[0016] As can be seen from the above, this device can automatically reduce the pressure inside the test tube, thus preventing the pressure inside the test tube from being too high for a long time. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1 As shown, a cell preservation solution shaking device with a fixed structure includes a base frame 1, and further includes: two first supports 2 disposed on the top of the base frame 1, a swing box 3 rotatably disposed between the two first supports 2, multiple fixing mechanisms disposed in the swing box 3 for fixing test tubes 8, a first driving mechanism for driving the swing box 3 to swing under its own gravity, clamping and collision mechanisms disposed on both sides of the swing box 3, and a plugging mechanism disposed above the swing box 3, wherein: The plug-removing mechanism includes a top frame 4, an electric cylinder 5 vertically downward mounted on the top frame 4, a mounting plate 6 mounted at the end of the telescopic rod of the electric cylinder 5, and multiple electromagnets 7 mounted at the bottom of the mounting plate 6. Each electromagnet 7 corresponds to a test tube plug 9 on a test tube 8 in the fixing mechanism. A magnetic component is fixedly mounted on the top of the test tube plug 9. The attraction force between the magnetic component and the electromagnet 7 is greater than the friction force between the test tube plug 9 and the sieve tube. When the swing box 3 swings, the clamping collision mechanism gradually approaches the swing box 3. The swing box 3 collides with the clamping collision mechanism to generate vibration until the swing box 3 is clamped. The bottom of the swing box 3 is in a straight position parallel to the horizontal plane. At this time, the plug-pulling mechanism starts to work.
[0023] During operation, the test tube 8 containing cell preservation solution is fixed in the swing box 3 by a fixing mechanism. Then, the first drive mechanism drives the swing box 3 to swing at a certain angle. After that, the connection with the swing box 3 is released. At this time, the swing box 3 swings back and forth under the action of gravity, which initially agitates the cell preservation solution. At the same time, as the swing box 3 swings, the clamping collision mechanism gradually approaches the swing box 3. The swing box 3 collides with the clamping collision mechanism to generate further oscillation and enhance the oscillation effect until the swing box 3 is clamped tightly and the bottom of the swing box 3 is in a horizontal position. At this time, the stopper removal mechanism starts to work. The electric cylinder 5 extends and drives the electromagnet 7 to descend so that the electromagnet 7 contacts the magnetic component. Then, the electromagnet 7 is energized and attracts the magnetic component. Then, the electric cylinder 5 shortens and pulls the test tube stopper 9 upward a certain distance, so that the air pressure in the test tube 8 is discharged outward. Then, the test tube stopper 9 is put back on, the electromagnet 7 is de-energized, the cylinder returns to the initial position, and then the cycle is repeated until the operation is completed.
[0024] As can be seen from the above, this device can automatically reduce the pressure inside the test tube 8 to avoid excessive pressure inside the test tube 8 for a long time.
[0025] like Figure 1 As shown, in some embodiments, the first drive mechanism includes a first motor 10 mounted on the base frame 1, a half gear 11 fixedly mounted on the rotating shaft of the first motor 10, and a spur gear 12 capable of meshing with the half gear 11, the spur gear 12 being fixedly mounted at one end of the swing box 3.
[0026] During operation, the first motor 10 drives the half gear 11 to rotate. When the half gear 11 meshes with the spur gear 12, it can drive the spur gear 12 to rotate, thereby causing the swing box 3 to swing at a certain angle. When the half gear 11 continues to rotate and does not mesh with the spur gear 12, the swing box 3 begins to swing back and forth spontaneously under the action of gravity, thereby causing the test tube 8 to swing back and forth, and initially agitating the cell preservation solution.
[0027] like Figure 2As shown, in some embodiments, the clamping and collision mechanism includes second brackets 13 disposed on both sides of the swing box 3, a bidirectional lead screw 14 rotatably disposed between the two second brackets 13, clamping and collision plates 15 threadedly connected to both sides of the bidirectional lead screw 14, a slide rod 16 disposed between the two second brackets 13 and slidingly passing through the clamping and collision plates 15, and a drive unit for driving the lead screw to rotate. Optionally, the drive unit is a second motor 17 disposed on the base frame 1, and the second motor 17 is connected to one end of the lead screw via a coupling 18.
[0028] During operation, the second motor 17 on the base frame 1 drives the bidirectional lead screw 14 to rotate via the coupling 18. Utilizing the opposing spiral threads on both sides of the lead screw, the two clamping collision plates 15, threaded onto the lead screw, move synchronously in opposite directions or in a straight line under the guidance and constraint of the slide rod 16. When the motor rotates forward, the clamping collision plates 15 on both sides rapidly approach each other along the lead screw axis. During this approach, the clamping plates collide with the swinging box 3, thereby further oscillating the test tube 8 and ultimately clamping and fixing the swinging box 3, facilitating subsequent plug removal. When the motor rotates in reverse, the clamping collision plates 15 separate in the opposite direction to release the swinging box 3. Throughout the process, the parallel arrangement of the slide rod 16 and the bidirectional lead screw 14 ensures smooth movement, while the precise control of the motor speed, direction, and torque enables dynamic adjustment of the clamping position, force, and collision parameters, ultimately achieving integrated and high-precision coordinated control of the clamping and collision functions.
[0029] like Figure 2 As shown, in some embodiments, a first elastic pad 19 is provided on both opposite surfaces of the two clamping collision plates 15. This can prevent the swing box 3 from colliding with the clamping collision plates 15 due to excessive rigidity.
[0030] like Figure 3 As shown, in some embodiments, the fixing mechanism includes a storage slot 20 disposed on the swing box 3, elastic telescopic members symmetrically disposed in the storage slot 20, and an arc-shaped clamping plate 21 disposed on one side of the elastic telescopic member. When it is necessary to clamp the test tube 8, the test tube 9 is inserted between the two arc-shaped clamping plates 21, and then the test tube 8 is pressed down so that the bottom of the test tube 8 contacts the bottom of the storage slot 20.
[0031] In some embodiments, the tops of the two arc-shaped clamping plates 21 extend outward to form a flared opening. The flared opening makes it easier for the test tube 8 to initially slide between the two arc-shaped clamping plates 21.
[0032] In some embodiments, a second elastic pad is provided at the bottom of the storage tank 20. The second elastic pad acts as a buffer for the bottom of the test tube 8.
[0033] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
[0034] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
