Description

Technical Field

[0001] The present invention relates to the technical field of test tube shaking equipment, and specifically to a test tube shaking equipment for hospital laboratories. Background Art

[0002] Test tubes are commonly used instruments in chemical laboratories and are used as reaction containers for a small amount of solution. In the hospital laboratory, blood samples are often placed in test tubes, and then shaken for a long time to make the solution in the test tube evenly distributed and accelerate the reaction. Since the shaking time and frequency directly affect the test results of blood samples, a test tube shaker is often used to shake the test tubes in the prior art.

[0003] The invention patent with the patent number CN114307770A discloses a test tube shaking equipment for hospital laboratories, belonging to the technical field of test tube shaking equipment, including a shaking box, a test tube for inspection, a control component, a fixing component, and a shaking driving component. The fixing component and the shaking driving component are arranged inside the shaking box, and the fixing component is arranged above the shaking driving component. The upper part of the test tube for inspection is installed at the fixing component, and the lower part of the test tube for inspection is located at the shaking driving component. The control component is arranged outside the shaking box and is electrically connected to the shaking driving component. This invention drives the test tube for inspection to swing and shake through the shaking driving component, greatly reducing the pulling force generated during the oscillation of the test tube, and at the same time being able to reduce the noise during the operation of the equipment and improving the mixing effect of the solution.

[0004] The above device drives the test tube for inspection to swing and shake through the shaking driving component, greatly reducing the pulling force generated during the oscillation of the test tube. However, due to the different amounts of liquid in the test tubes, different tilting angles are required. The less the liquid, the insufficient fluidity of the liquid leads to difficult mixing, so the tilting angle needs to be increased to ensure the mixing effect. When there is more liquid, a smaller tilting angle is required to avoid splashing of the solution. However, due to the large number of test tubes, it is very troublesome to set different tilting angles for the solutions in different test tubes, and it is impossible to identify the amount of solution inside different test tubes. Using the same mixing method for test tubes with different amounts of solution not only results in poor mixing effect but also easily causes splashing of the solution. Summary of the Invention

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-8, an embodiment provided by the present invention: a test tube shaking device for a hospital laboratory, including a box body 1. Four mounting rods 4 are fixedly arranged inside the box body 1. A number of universal clamping mechanisms 2 are arranged between the four mounting rods 4. A number of shaking motors 7 are arranged inside the box body 1. A reset mechanism 6 is arranged on the top of the number of shaking motors 7. A conical cylinder 3 is respectively and limitedly inserted on the top of the number of reset mechanisms 6. A limiting groove 10 is arranged inside the number of conical cylinders 3. A measuring mechanism 5 is arranged inside the number of limiting grooves 10. A reciprocating mechanism 8 for increasing the shaking angle is arranged on the side wall of the number of measuring mechanisms 5. An installation block 11 is arranged on the top of the number of measuring mechanisms 5. A circular groove 111 for inserting a test tube is arranged on the top of the installation block 11. Place the test tube to be shaken and mixed in the universal clamping mechanism 2, and make the bottom insert into the circular groove 111. The weight of the solution inside the test tube drives the measuring mechanism 5 to move down along the inclined groove. Then, the output shaft of the shaking motor 7 rotates to drive the reset mechanism 6 and the conical cylinder 3 to rotate. The rotation of the conical cylinder 3 drives the installation block 11 to rotate synchronously. And because the installation block 11 is arranged at the eccentric position of the conical cylinder 3, the centrifugal force when the conical cylinder 3 rotates drives the installation block 11 to slide on the measuring mechanism 5 to the edge close to the measuring mechanism 5. If there is very little liquid inside the test tube, at this time, the weight of the solution cannot drive the measuring mechanism 5 to move. At this time, the reciprocating mechanism 8 is in a mutually driving state. When the shaking motor 7 drives the conical cylinder 3 to rotate, the synchronous reciprocating mechanism 8 drives the installation block 11 to reciprocate synchronously, thereby increasing the mixing efficiency when the solution is less, and avoiding problems such as uneven mixing or even sedimentation of less solution.

[0028] Specifically, each of the number of universal clamping mechanisms 2 includes two torsion springs 21, two clamping jaws 22 and two clamping shafts 23. The two clamping shafts 23 are respectively rotatably arranged on the side walls of the corresponding mounting rods 4. The two clamping jaws 22 are ball-headed at one end of the clamping shaft 23 away from the mounting rod 4. The two ends of the two torsion springs 21 are respectively fixedly arranged on the clamping shaft 23 and the mounting rod 4. The side wall of the test tube is clamped by the clamping jaws 22. And because the clamping jaws 22 are ball-connected with the clamping shafts 23, the test tube can still maintain a stable clamping effect when rotating.

[0029] Specifically, several of the measurement mechanisms 5 each include two measurement components, two long slots 55, two sliding rods 56, two annular rods 57, and two U-shaped limiting rods 510. The two measurement components are symmetrically arranged, and one end of each of the two measurement components is slidably located in the corresponding limiting slot 10, and the two measurement components are fixedly connected to each other. The two annular rods 57 are respectively fixedly arranged on the two side walls of one of the measurement components. One end of each of the two sliding rods 56 is fixedly arranged on the two side walls of the measurement component. The two long slots 55 are respectively arranged on the two sliding rods 56. The two U-shaped limiting rods 510 are respectively fixedly arranged at the bottom of the mounting block 11, and the two U-shaped limiting rods 510 are slidably located inside the corresponding long slots 55.

[0030] Specifically, each measurement component includes a first U-shaped plate 51, a second U-shaped plate 52, a third U-shaped plate 53, two limiting strips 54, an inclined plate 58, and a return spring 59. The inclined plate 58 is slidably arranged inside the inclined slot. The third U-shaped plate 53 is fixedly arranged on the inclined plate 58. The second U-shaped plate 52 is slidably sleeved on the third U-shaped plate 53. The two limiting strips 54 are respectively fixedly arranged on the tops of the second U-shaped plate 52 and the third U-shaped plate 53. The first U-shaped plate 51 is slidably sleeved on the second U-shaped plate 52. The two ends of the return spring 59 are respectively fixedly arranged on the third U-shaped plate 53 and the first U-shaped plate 51. A round hole for the return spring 59 to pass through is arranged in the middle of the second U-shaped plate 52. The two sliding rods 56 are fixedly connected to the side wall of the third U-shaped plate 53. The two annular rods 57 are respectively fixedly arranged on the two side walls of the first U-shaped rod. Under the action of the gravity of the solution inside the test tube, the mounting block 11 is driven to press down. When the mounting block 11 presses down, it drives the first U-shaped plate 51, the second U-shaped plate 52, and the third U-shaped plate 53 to move downward synchronously, and drives the inclined plate 58 to slide along the inclined slot, and synchronously drives the third U-shaped plate 53 and the second U-shaped plate 52 to insert into each other. When the third U-shaped plate 53 inserts into the second U-shaped plate 52, it drives the sliding rods 56 to move synchronously. The movement of the sliding rods 56 causes the position of the long slot 55 to move, so that the position of the U-shaped limiting rod 510 changes. Thus, when the conical tube 3 rotates, the distance that the mounting block 11 moves towards the edge of the conical tube 3 changes, so that the inclination angle of the test tube is reduced; it realizes the adaptive adjustment of the inclination angle of the test tube in the case of different solution volumes, avoids splashing of the solution when the oscillation angle is too large when the solution is more, and increases the inclination angle of the test tube when the solution is less, ensuring its mixing rate.

[0031] Specifically, several of the reciprocating mechanisms 8 each include a reciprocating plate 81, a reciprocating lead screw 82, a first gear 83, a second gear 84, a transmission shaft 85, a smooth rod 86, an L-shaped plate 87, and a reciprocating motor 88. The L-shaped plate 87 is fixedly arranged at the bottom of the third U-shaped plate 53. The reciprocating motor 88 is fixedly arranged on the L-shaped plate 87. The transmission shaft 85 is fixedly arranged at the end of the output shaft of the reciprocating motor 88. The first gear 83 is fixedly arranged at the end of the transmission shaft 85. The reciprocating plate 81 is fixedly arranged on the side wall of the slide bar 56. The smooth rod 86 is arranged on the L-shaped plate 87 in a limited plug-in manner. One end of the reciprocating lead screw 82 is rotatably arranged at the end of the smooth rod 86. The second gear 84 is fixedly arranged on the reciprocating lead screw 82. The reciprocating plate 81 is in meshing transmission cooperation with the reciprocating lead screw 82. When the solution is less, at this time, the first gear 83 and the second gear 84 are meshed and driven with each other. The output shaft of the reciprocating motor 88 rotates to drive the first gear 83 to rotate. The first gear 83 rotates to drive the second gear 84 to rotate. The second gear 84 rotates to drive the reciprocating lead screw 82 to rotate. It should be noted that: there is a certain frictional force between the smooth rod 86 and the L-shaped plate 87. When the reciprocating lead screw 82 rotates, due to the frictional force between the smooth rod 86 and the L-shaped plate 87, the reciprocating lead screw 82 cannot drive the smooth rod 86 and itself to move, thereby driving the reciprocating plate 81 to move. The reciprocating plate 81 moves to drive the slide bar 56 to move synchronously. The movement of the slide bar 56 causes the long groove 55 to move. The movement of the long groove 55 causes the U-shaped limiting rod 510 and the mounting block 11 to move synchronously. And due to the action of centrifugal force, the mounting block 11 is always at the outermost end of the long groove 55, so that the movement of the slide bar 56 drives the mounting block 11 to move synchronously. When the solution in the test tube is less and the test tube is tilted at the maximum angle corresponding to the oscillation, the oscillation angle of the test tube is reciprocally adjusted, and the test tube is mixed and oscillated at multiple angles, increasing the solution disturbance, reducing the stratification residue, and increasing the mixing effect.

[0032] Specifically, the reset mechanism 6 includes a U-shaped reset plate 61 and a plurality of reset components. The U-shaped reset plate 61 is slidably arranged on the side wall of the box body 1. The plurality of reset components are arranged on the U-shaped reset plate 61. Each of the reset components includes a cone ring 62, an inner rod 63, a circular groove 64, two semicircular sleeve rods 65, two semi-conical rings 66, a limiting sleeve 67, a plurality of first wedge blocks 68, a resisting spring 69, two connecting springs 610, two second springs 611 and two second wedge blocks 612. The limiting sleeve 67 is fixedly arranged on the output shaft of the oscillation motor 7. The two semicircular sleeve rods 65 are plugged and arranged on the limiting sleeve 67. The two semi-conical rings 66 are respectively fixedly arranged The first wedge blocks 68 are fixedly arranged on the inner wall of the two semicircular sleeve rods 65, and the two second springs 611 are fixedly arranged inside the inner rod 63. The two second wedge blocks 612 are fixedly arranged at the ends of the two second springs 611, and the two second wedge blocks 612 are respectively inserted into the side walls of the inner rod 63. The circular groove 64 is arranged inside the U-shaped reset rod, and the cone ring 62 is rotatably arranged inside the circular groove 64. The two connecting springs 610 are respectively fixedly arranged between the two semicircular sleeve rods 65. The weight of the solution drives the inner rod 63 to move downward to compress the resistance spring 69, and the inner rod 63 moves downward to drive the second wedge block 612 to move downward until the corresponding second wedge blocks 612 are engaged, and the output shaft of the oscillation motor 7 rotates to drive the limit sleeve 67 to rotate synchronously, and the limit sleeve 67 drives the two semicircular sleeve rods 65 to rotate, and the rotation of the semicircular sleeve rod 65 drives the inner rod 63 and the conical tube 3 to rotate synchronously. When use is completed, the U-shaped reset plate 61 is lifted to drive the cone ring 62 to move synchronously, and the cone ring 62 moves to make the semi-conical ring disengage from the limit, and under the action of the connecting spring 610 The first wedge block 68 and the second wedge block 612 are separated, so that the first wedge block 68 and the second wedge block 612 are disengaged, and the inner rod 63 is reset under the action of the resistance spring 69; after use, the test tube is taken out and the U-shaped reset plate 61 is pulled up to reset all the inner rods 63. The next time it is used, the U-shaped reset plate 61 is pressed down again. The operation is simple, convenient and fast. In addition, by setting the first wedge block 68 and the second wedge block 612, the stability of the measuring mechanism 5 is guaranteed when the conical tube 3 rotates, and the upward movement of the measuring mechanism 5 due to the centrifugal force is avoided, thereby ensuring its mixing efficiency.

[0033] Specifically, a plug-in plate 12 is disposed on the side wall of each of the semicircular sleeve rods 65 , and a receiving groove for movably plugging the plug-in plate 12 is disposed inside each of the conical cylinders 3 .

[0034] Working principle: Place the test tube that needs to be oscillated and mixed in the jaw 22. Clamp the side wall of the test tube through the jaw 22. Since the jaw 22 is connected to the clamping shaft 23 by a ball head, the test tube can still maintain a stable clamping effect when rotating, and the bottom of the test tube is inserted into the circular groove 111. Driven by the gravity of the solution inside the test tube, the mounting block 11 is pressed down. The downward pressure of the mounting block 11 drives the first U-shaped plate 51, the second U-shaped plate 52 and the third U-shaped plate 53 to move downward synchronously, and drives the inclined plate 58 to slide along the inclined groove, and synchronously drives the third U-shaped plate 53 and the second U-shaped plate 52 to insert into each other. The insertion of the third U-shaped plate 53 into the second U-shaped plate 52 drives the slide bar 56 to move synchronously. The movement of the slide bar 56 changes the position of the long groove 55, thereby changing the position of the U-shaped limiting rod 510. When the conical cylinder 3 rotates, the distance that the mounting block 11 moves toward the edge of the conical cylinder 3 changes, so that the inclination angle of the test tube decreases. Then, driven by the weight of the solution, the inner rod 63 moves downward to compress the abutting spring 69. The downward movement of the inner rod 63 drives the second wedge block 612 to move downward until the corresponding second wedge blocks 612 are clamped. And the output shaft of the oscillation motor 7 rotates to drive the limit sleeve 67 to rotate synchronously. The limit sleeve 67 drives the two semi-circular sleeve rods 65 to rotate. The rotation of the semi-circular sleeve rods 65 drives the inner rod 63 and the conical cylinder 3 to rotate synchronously. The rotation of the conical cylinder 3 drives the mounting block 11 to rotate synchronously, and the solution is oscillated and mixed at a certain inclination angle. When it is used up, lift the U-shaped reset plate 61 to drive the conical ring 62 to move synchronously. The movement of the conical ring 62 causes the semi-conical ring to be released from the limit, and under the action of the connecting spring 610, they are separated, so that the first wedge block 68 and the second wedge block 612 are disengaged from the clamping, and the inner rod 63 is reset under the action of the abutting spring 69. The rotation of the conical cylinder 3 drives the mounting block 11 to rotate synchronously. And since the mounting block 11 is arranged at the eccentric position of the conical cylinder 3, when the conical cylinder 3 rotates, due to the action of centrifugal force, the mounting block 11 is always located at the outermost end of the long groove 55. When the solution is less, at this time, the first gear 83 and the second gear 84 are meshed and driven. The output shaft of the reciprocating motor 88 rotates to drive the first gear 83 to rotate. The rotation of the first gear 83 drives the second gear 84 to rotate. The rotation of the second gear 84 drives the reciprocating lead screw 82 to rotate. It should be noted that: there is a certain frictional force between the optical rod 86 and the L-shaped plate 87. When the reciprocating lead screw 82 rotates, due to the frictional force between the optical rod 86 and the L-shaped plate 87, the reciprocating lead screw 82 cannot drive the optical rod 86 and itself to move, thereby driving the reciprocating plate 81 to move. The movement of the reciprocating plate 81 drives the slide bar 56 to move synchronously. The movement of the slide bar 56 makes the long groove 55 move. The movement of the long groove 55 makes the U-shaped limiting rod 510 and the mounting block 11 move synchronously. And due to the action of centrifugal force, the mounting block 11 is always at the outermost end of the long groove 55, so that the movement of the slide bar 56 drives the mounting block 11 to move synchronously.
