Description

Technical Field

[0001] The present invention relates to the technical field of molecular identification of traditional Chinese medicines, and particularly relates to a water bath device for molecular identification of traditional Chinese medicines. Background Art

[0002] The core function of the water bath operation in the molecular identification of traditional Chinese medicines is to achieve precise temperature control, providing a constant temperature environment guarantee for key molecular biology experimental links such as DNA extraction, PCR amplification, and enzymatic digestion. Its core roles include: DNA denaturation / renaturation, such as the thermal denaturation of template DNA before PCR (95°C) or the temperature maintenance in nucleic acid hybridization experiments; enzymatic reactions, reactions that rely on a constant temperature environment such as restriction endonuclease digestion (37°C) or reverse transcription reaction (42 - 50°C); sample treatment temperature maintenance, such as cell lysis during DNA extraction by the CTAB method (65°C) or the sol process in agarose gel recovery (45 - 55°C), etc.; as a low-cost constant temperature device, providing basic temperature control support when professional instruments are lacking, such as when there is no PCR instrument, the water bath can achieve simple temperature control.

[0003] In some reaction systems (such as DNA extraction by the CTAB method), long-term static placement may cause the sample and the lysis solution to separate layers. By shaking, the two can be fully mixed, thereby improving the cell lysis and DNA extraction efficiency. Therefore, during the actual operation process, in order to promote the full mixing of reactants and accelerate the reaction process, it is necessary to take out the EP tube containing the sample from the water bath and shake it at regular intervals. It should be noted that during the non-shaking static period of the sample, the solid components in the sample will still gradually settle to the bottom of the tube due to the action of gravity. This repeated dynamic process of precipitation and resuspension will cause fluctuations in the contact area between the cell wall / membrane and the lysis solution, not only affecting the stability of cell lysis efficiency, but also causing some DNA to be trapped in the precipitate and difficult to completely free up to the supernatant. In addition, manual shaking cannot fully mix the reactants, and there is a risk of scalding caused by steam or hot water splashing during high-temperature water bath operations. Summary of the Invention

[0004] One of the purposes of the present invention is to provide a water bath device for molecular identification of traditional Chinese medicines. Based on the rotation connection between the water bath tank and the main housing assembly, in cooperation with the cylindrical seat fixedly connected to the outside of the main housing assembly and the sliding connection formed by the spherical seat elastically slidably connected to the outer bottom end of the fixed rod and the outer top surface of the cylindrical seat and the guiding chute, multiple mixing and swinging actions of the EP tubes loaded on the placement rack can be formed to ensure full mixing of the reactants.

[0005] The object of the present invention is achieved by such a technical solution. A water bath device for molecular identification of traditional Chinese medicinal materials includes a main housing assembly, a water bath assembly, a combined swing frame assembly, and a placement structure member. The water bath assembly includes a water bath tank. The combined swing frame assembly includes a connecting link, a fixed rod, and a cylindrical seat. The placement structure member includes a placement rack, a tube sleeve, an EP tube, and a pushing hole;

[0006] The water bath tank is rotatably connected to the inner top end of the main housing assembly. On one side of the inside of the water bath tank, main connecting rods are symmetrically and rotatably connected. The connecting link is rotatably connected between the other ends of the main connecting rods. The main connecting rods and the connecting link form a parallelogram structure. At the top of the rotating shaft at one end of one group of main connecting rods, a fixed rod is fixedly connected. The cylindrical seat is fixedly connected to the outside of the main housing assembly. At the other end of the fixed rod, a ball head seat with elastic downward sliding is connected. On the outer top surface of the cylindrical seat, a guiding chute is fixed. The ball head seat is both slidably connected to the outer top surface of the cylindrical seat and slidably connected to the guiding chute;

[0007] On one side of each group of main connecting rods, a conical insertion post is fixed. On one side of the placement rack, a conical insertion sleeve is fixed. After the other side of the placement rack is slidably inserted with the other side of the main connecting rod, the conical insertion sleeve can be engaged and matched with the conical insertion post;

[0008] The tube sleeves are arranged and fixedly connected to the placement rack. An EP tube can be inserted and installed in each tube sleeve. The pushing hole is opened at a position in the main body of the placement rack opposite to the conical insertion sleeve. In the middle of the top end of the placement rack, an outward moving insertion seat is fixed.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] The water bath tank is used to hold distilled water, and the distilled water is heated to a set temperature by a heating mechanism. The EP tube is used to hold the DNA sample of traditional Chinese medicinal materials and is tightly sealed;

[0011] After the set water temperature of the distilled water in the water bath tank is stable, with the placement rack inserted and connected to the main connecting rod, the EP tube containing the DNA sample of traditional Chinese medicinal materials is inserted and installed into the tube sleeve in place, and the EP tube is immersed in the distilled water in the water bath tank;

[0012] Start the rotation driving mechanism connected to the water bath tank to drive the water bath tank to rotate reciprocally within a certain range. It can not only drive the EP tube to rotate along with the rotation of the water bath tank, forming a mixing action in the first direction of the EP tube, but also make the distilled water with the set water temperature in the water bath tank in a flowing state, ensuring that the EP tube is in a state of uniform heating;

[0013] When rotating reciprocally within a certain range in the water bath tank, it can drive the ball head seat elastically slidably connected to the lower end outside the fixed rod to form a sliding tangential fit with the outer top surface of the cylindrical seat, enabling the ball head seat to move along the arc-shaped surface formed by the outer top surface of the cylindrical seat. The purpose of setting the guiding chute is to limit the fitting path of the ball head seat and the arc-shaped surface formed by the outer top surface of the cylindrical seat, thereby driving the fixed rod to form a reciprocating rotation within a certain range;

[0014] The fixed rod drives the parallelogram structure composed of the main connecting rod and the connecting link to form a rotating motion, which can drive the EP tube inserted and installed in the tube sleeve to form a reciprocating rotating and mixing motion in the second direction in the water bath tank;

[0015] After the water bath is completed, the outer surface of the top end of the conical plug is inwardly pressed through the pushing hole, so that the conical plug is disengaged from the clamping fit with the conical socket, and the placement rack carrying the EP tube and the tube sleeve are quickly taken out to enter the subsequent termination reaction step.

[0016] The water bath device for molecular identification of traditional Chinese medicine in the present invention further includes an opposing stabilizing member and an outer rotating arm assembly. The opposing stabilizing member includes an auxiliary fixing frame, an outer sliding seat and a vertical rod. The outer rotating arm assembly includes a rotating arm and a release pushing sleeve;

[0017] The inner lower end of the auxiliary fixing frame is fixedly connected to the top end of the connecting link. The outer side of the water bath tank is symmetrically fixedly connected with outer guide columns. The outer ends of the outer guide columns are connected and fixed with side seats, and the outer sliding seat is slidably connected with the outer guide columns;

[0018] The vertical rods are fixedly connected in pairs to the top ends of the outer sliding seats. Each group of vertical rods is rotatably connected with a rotating column. The rotating column is slidably connected with the chute opened on the outer side of the upper end of the auxiliary fixing frame. Flexible support seats are arranged on both the upper and lower sides of the rotating column, and the flexible support seats are fixedly connected with the vertical rods. The two groups of flexible support seats are respectively clamped on the upper and lower sides of the outer main body of the auxiliary fixing frame;

[0019] When the parallelogram structure composed of the connecting link and the main connecting rod performs a rotating motion, in cooperation with the sliding connection in the first direction formed by the outer sliding seat and the outer guide column, and the sliding connection in the second direction formed by the rotating column and the auxiliary fixing frame, the support stability of one end of the connecting link can be improved;

[0020] The rotating arm is rotatably connected to the outside of the main housing assembly and can rotate automatically. Release electric cylinders are installed and fixed on both sides of the top end of the rotating arm. The bottom end of the telescopic rod of the release electric cylinder is fixedly connected with a pushing seat, and the release pushing sleeve is fixedly connected with the bottom surface of the pushing seat;

[0021] The top end of the rotating arm is also fixedly connected with safety snap sleeves in pairs;

[0022] And after the rotation of the water bath tank stops at the position where the top end is parallel to the top surface of the main housing assembly, the parallelogram structure composed of the main connecting rod and the connecting link can just rotate and form a rectangular structure;

[0023] And when the rotation of the water bath tank stops at a position where the top end is parallel to the top surface of the main housing assembly, after the parallelogram structure formed by the main connecting rod and the connecting link synchronously rotates and displaces to form a rectangular structure, with the upward rotation of the rotating arm, the safety card sleeve can be inserted into the connecting arm of the auxiliary fixing frame. Thus, after the rotating arm is rotated to a position where the pushing seat is parallel to the top surface of the main housing assembly, the clamping fit formed by the safety card sleeve and the auxiliary fixing frame is released, and the position of the release push sleeve is exactly opposite to the position of the pushing hole opened in the main body of the placement rack. After starting the release electric cylinder to drive the pushing seat and the release push sleeve to move downward, the inner hole of the release push sleeve can be sleeved on the outer surface of the tapered plug inserted into the pushing hole. As the release push sleeve continues to move downward, it can drive the tapered plug to form an inward contraction action. After the tapered plug contracts, the clamping fit formed by the tapered plug and the tapered socket fails, and at this moment, there is enough clearance between the bottom end of the pushing seat and the top end of the placement rack. The placement rack can be moved upward relative to the main connecting rod by a certain distance, and after the release push sleeve is retracted and the rotating arm rotates outward to a position where it does not interfere with the removal of the placement rack, the placement rack carrying the EP tube can be taken out from the water bath tank.

[0024] By adopting the above technical solutions, the present invention can achieve the following beneficial effects:

[0025] (1) Based on the rotational connection between the water bath tank with a cylindrical structure cavity and the main housing, the present invention can form a state where the water bath tank reciprocally rotates within a certain range. Since the water bath tank can not only hold distilled water for water bath but also be used to place EP tubes, when the water bath tank reciprocally rotates, it can not only improve the fluidity of the distilled water in the water bath tank to a certain extent, eliminate the temperature gradient of the distilled water in the water bath tank, make the EP tubes evenly heated, but also form a mixing and shaking action on the EP tubes to promote the full mixing of reactants;

[0026] (2) The present invention also has a parallelogram structure composed of a main connecting rod and a connecting link in the water bath tank, and the placement rack for placing EP tubes is detachably inserted and connected with the main connecting rod. Moreover, a ball head seat is elastically slidably connected to the outer lower end of the fixed rod at the top end of one set of main connecting rod spindles. The ball head seat can not only form a sliding tangential fit with the arc-shaped surface formed on the outer top surface of the cylindrical seat but also form a sliding tangential fit with the guiding chute. When the water bath tank reciprocally rotates within a certain range, the parallelogram structure formed by the main connecting rod and the connecting link can form a reciprocating rotational displacement action, thereby driving the EP tubes to move and mix in the distilled water in the water bath tank, achieving the purpose of improving the reaction efficiency in multiple ways.

[0048] As Figures 1 - 16 shown, a water bath device for molecular identification of traditional Chinese medicines, the water bath tank 202 is rotatably connected to the inner top end of the main housing assembly 1 and can rotate reciprocally within a certain range. The top opening of the water bath tank 202 is always located outside the main housing assembly 1. On one side inside the water bath tank 202, main connecting rods 303 are symmetrically and rotatably connected. A connecting link 304 is rotatably connected between the other ends of the main connecting rods 303. The main connecting rods 303 and the connecting link 304 form a parallelogram structure. At the top of the rotating shaft at one end of a group of main connecting rods 303, a fixed rod 306 is fixedly connected. A cylindrical seat 307 is fixedly connected to the outside of the main housing assembly 1. At the other end of the fixed rod 306, a ball head seat 309 with elastic downward is slidably connected. A guiding chute 308 is fixed on the outer top surface of the cylindrical seat 307. The ball head seat 309 is slidably connected to both the outer top surface of the cylindrical seat 307 and the guiding chute 308;

[0049] The inner lower end of the auxiliary fixing frame 401 is fixedly connected to the top end of the connecting link 304. On the outer side surface of the water bath tank 202, outer guide columns 402 are symmetrically and fixedly connected. At the outer end of the outer guide column 402, a side seat 403 is connected and fixed. An outer sliding seat 404 is slidably connected to the outer guide column 402;

[0050] Vertical rods 405 are fixedly connected in pairs to the top ends of the outer sliding seats 404. In each group of vertical rods 405, a rotating column 406 is rotatably connected. The rotating column 406 is slidably connected to the chute opened on the outer side of the upper end of the auxiliary fixing frame 401. Flexible support seats 407 are provided on both the upper and lower sides of the rotating column 406, and the flexible support seats 407 are fixedly connected to the vertical rods 405. The two groups of flexible support seats 407 are respectively clamped on the upper and lower sides of the outer main body of the auxiliary fixing frame 401, which can improve the reliability of the sliding connection between the rotating column 406 and the auxiliary fixing frame 401;

[0051] When the parallelogram structure formed by the connecting link 304 and the main connecting rods 303 performs a rotating action, it can cooperate with the sliding connection in the first direction formed by the outer sliding seat 404 and the outer guide column 402, and the sliding connection in the second direction formed by the rotating column 406 and the auxiliary fixing frame 401, which can improve the support stability of one end of the connecting link 304;

[0052] At one side of the top end of each main connecting rod 303, a conical insertion post 507 is fixed. At one side of the placement rack 501, a conical insertion sleeve 508 is fixed. After the other side of the placement rack 501 is slidably inserted with the other side of the main connecting rod 303, the conical insertion sleeve 508 can be engaged and cooperated with the conical insertion post 507;

[0053] The pipe sleeves 504 are arranged and fixedly connected with the placement rack 501. An EP pipe 506 can be inserted and installed in each pipe sleeve 504. A pushing hole 509 is opened at a position in the main body of the placement rack 501 opposite to the conical insertion sleeve 508. After the conical insertion sleeve 508 is engaged and cooperated with the conical insertion post 507 in place, it can pass through the pushing hole 509 to inwardly press the outer surface of the top end of the conical insertion post 507, so that the conical insertion post 507 is disengaged from the engagement and cooperation with the conical insertion sleeve 508;

[0054] The working principle is as follows:

[0055] The EP pipe 506 is used to hold the DNA sample of traditional Chinese medicine and is tightly sealed to prevent contamination;

[0056] The water bath tank 202 is used to hold distilled water, and the distilled water is heated to a set temperature by a heating mechanism. The purpose of adding distilled water is to prevent scaling;

[0057] After the set water temperature of the distilled water in the water bath tank 202 is stable, in the state where the placement rack 501 is inserted and connected with the main connecting rod 303, the EP pipe 506 containing the DNA sample of traditional Chinese medicine is inserted and installed into the pipe sleeve 504 in place, and the EP pipe 506 is immersed in the distilled water in the water bath tank 202;

[0058] Start the rotary drive mechanism connected to the water bath tank 202 to drive the water bath tank 202 to reciprocally rotate within a certain range. Since the main connecting rod 303 is installed inside the water bath tank 202, the placement rack 501 is inserted and connected with the main connecting rod 303, and the EP pipe 506 is inserted and installed into the pipe sleeve 504. When the water bath tank 202 reciprocally rotates within a certain range, it can not only drive the EP pipe 506 to rotate along with the rotation of the water bath tank 202, forming a mixing action in the first direction of the EP pipe 506, but also make the distilled water with the set water temperature in the water bath tank 202 in a flowing state, ensuring that the EP pipe 506 is in a state of being evenly heated;

[0059] When rotating reciprocally within a certain range in the water bath tank 202, it can drive the ball head seat 309 elastically slidably connected to the lower end outside the fixed rod 306 to form a sliding tangential fit with the outer top surface of the cylindrical seat 307, enabling the ball head seat 309 to move along the arc-shaped profile formed by the outer top surface of the cylindrical seat 307. The purpose of setting the guiding chute 308 is to limit the fitting path of the arc-shaped profile formed by the ball head seat 309 and the outer top surface of the cylindrical seat 307, so that within the range where the ball head seat 309 forms a sliding tangential fit with the ball head seat 309, the ball head seat 309 safely and maintains a certain path to form a sliding tangential fit with the arc-shaped profile formed by the outer top surface of the cylindrical seat 307, thereby driving the fixed rod 306 to form a reciprocating rotation within a certain range;

[0060] The fixed rod 306 drives the parallelogram structure composed of the main connecting rod 303 and the connecting link 304 to form a rotating action, which can drive the EP tube 506 inserted and installed in the tube sleeve 504 to form a reciprocating rotational mixing action in the second direction within the water bath tank 202, improving the cracking efficiency multiple times;

[0061] After the water bath is completed, the outer surface of the top end of the conical plug post 507 is inwardly pressed through the pushing hole 509, so that the conical plug post 507 is disengaged from the clamping fit with the conical socket 508, and the placement rack 501 carrying the EP tube 506 and the tube sleeve 504 are quickly taken out to enter the subsequent termination reaction step.

[0062] The specific structures of the main housing assembly 1 and the water bath assembly 2 are as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown. The main controller 102 is fixedly installed on one side of the front end of the main housing 101 for controlling the device. A rotation position 103 is provided at the top end of the main housing 101 to provide space for the rotation action of the water bath tank 202;

[0063] Rotating main seats 201 are symmetrically and fixedly installed inside the main housing 101. The water bath tank 202 is rotatably connected to the rotating main seats 201 through the rotating main shafts 203 at both ends;

[0064] A heating seat 206 is fixedly installed on the side of one end of the main body of the water bath tank 202. A pair of electric heating rods 208 are fixedly installed in the heating seat 206, and the electric heating rods 208 are hermetically connected to the heating seat 206, so that the distilled water in the water bath tank 202 will not leak;

[0065] An inner partition 204 is fixedly connected inside the water bath tank 202. A safety partition net 205 is installed and fixed inside the inner partition 204. The purpose of setting the safety partition net 205 is to isolate the electric heating rods 208 from the EP tube 506 in the space above the safety partition net 205, playing a protective role for the EP tube 506;

[0066] Symmetrically and fixedly connected to the middle part on the outside of the water bath tank 202 are rotary swing arms 207. A rotary motor 209 is fixedly installed on the inner top surface of the main housing 101. The inner vertical seat 210 is also fixedly connected to the inner top surface of the main housing 101. The rotating shaft of the rotary motor 209 passes through the inner vertical seat 210 and is fixedly connected to the driving gear 211;

[0067] The bottom end of the inner vertical seat 210 is rotatably connected horizontally with a transmission shaft 217. A rotary gear 212 is inserted and fixed in the middle of the transmission shaft 217. The rotary gear 212 meshes with the driving gear 211. Starting the rotary motor 209 can cause the driving gear 211 and the rotary gear 212 to form a cooperative transmission, driving the rotary gear 212 to perform a rotating action;

[0068] Both ends of the transmission shaft 217 are fixedly connected with eccentric wheels 213. The eccentric ends on the outside of each group of eccentric wheels 213 are fixedly connected with eccentric columns 214. The eccentric columns 214 on the same side are slidably connected to the sliding grooves formed in the rotary swing arms 207. When the rotary gear 212 drives the eccentric wheels 213 coaxially through the transmission shaft 217, the eccentric columns 214 connected to the eccentric ends of the eccentric wheels 213 form a sliding fit with the rotary swing arms 207, so that the water bath tank 202 can be driven to rotate reciprocally within a certain range with the rotary main seat 201 as the reference;

[0069] Moreover, the water bath tank 202 is in a slow and uniform reciprocating rotation state, and the distilled water in the water bath tank 202 will not splash out;

[0070] The photoelectric sensor receiving module 215 and the photoelectric sensor transmitting module 216 together form a photoelectric sensor. The photoelectric sensor transmitting module 216 is fixedly installed at the outer end of one of the eccentric columns 214, and the photoelectric sensor receiving module 215 is fixedly installed on the inner top surface of the main housing 101. Through the photoelectric induction formed by the photoelectric sensor transmitting module 216 and the photoelectric sensor receiving module 215, the rotation of the eccentric column 214 can be positioned at a certain set position to stop the water bath tank 202 at a position parallel to the top surface of the main housing 101 at the top;

[0071] And if necessary, a temperature sensor can be installed in the water bath tank 202 to accurately control the water temperature of the distilled water in the water bath tank 202;

[0072] And during a single operation process, the water bath tank 202 is filled with a sufficient amount of distilled water, which is sufficient to complete the current operation.

[0073] The specific structures of the combined swing frame assembly 3 and the placement structure member 5 are as shown in Figure 7 、 Figure 8 、 Figure 10 and Figure 11As shown in the figure, a pair of inner rotation seats 301 are fixedly connected to one side inside the water bath tank 202. An inner rotation shaft 302 is rotatably connected in each group of inner rotation seats 301. One end of the main connecting rod 303 is fixedly connected to the inner rotation shaft 302;

[0074] The top end of one group of inner rotation shafts 302 is coaxially and fixedly connected with an outer connecting shaft 305. One end of the fixed rod 306 is fixedly connected to the top end of the outer connecting shaft 305. A through hole that rotates and interferes with the outer connecting shaft 305 is formed in the main body of the water bath tank 202;

[0075] The other end of the fixed rod 306 is fixedly installed with a spring column sliding seat 310. The top end of the ball head seat 309 is fixedly connected with a bottom limit plate 312. The top end of the bottom limit plate 312 is fixedly connected with a spring column 311. The spring column 311 is slidably connected with the spring column sliding seat 310. A top spring 313 is sleeved and installed in the spring column 311. One end of the top spring 313 is clamped to the bottom limit plate 312, and the other end is clamped to the fixed rod 306, which can form a state where the ball head seat 309 elastically moves downward, so that with the reciprocating rotation action of the water bath tank 202, the ball head seat 309 is always in a state of sliding tangentially and mating with the top surface of the columnar seat 307 and the guiding chute 308;

[0076] The top end of the spring column 311 is fixedly connected with a top limit plate 314, which is used to form a safety limit for the sliding fit formed by the spring column 311 and the spring column sliding seat 310;

[0077] The other side of the placement rack 501 is fixedly connected with an arc socket 502. An arc slot 503 is formed on the other side of the main connecting rod 303. The arc socket 502 can form a sliding plug-in fit with the arc slot 503;

[0078] The inner surface of each group of tube sleeves 504 is arranged and fixedly connected with inner fins 505 made of silica gel structure. The purpose of setting the inner fins 505 is to utilize the inner fins 505 to form a flexible elastic support structure, which is more convenient for safely inserting the EP tube 506. The outer moving plug socket 510 is fixedly installed in the middle of the top end of the placement rack 501;

[0079] Not only are teeth for mutual clamping and matching formed on the outer surface of the conical plug post 507 and the inner surface of the conical socket 508, but also cruciform grooves are formed in the main bodies of the conical plug post 507 and the conical socket 508, which is convenient for the conical socket 508 to form an elastic plug-in fit with the conical plug post 507.

[0080] The specific structures of the outer rotation arm assembly 6 and the outer moving plug-in assembly 7 are as shown in Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16 shown. The rotation arm fixed seat 601 is fixedly connected to the outer side surface of the main housing 101. The bottom end of the rotation arm 602 is rotatably connected to the rotation arm fixed seat 601;

[0081] A moving shaft 603 is fixedly connected horizontally to the middle part of the main body of the rotating arm 602. An electric cylinder fixed rotation seat 604 is fixedly connected to the outer side surface of the main housing 101. The bottom end of the main body of the servo electric cylinder 605 is rotatably connected to the electric cylinder fixed rotation seat 604, and the top end of the telescopic rod of the servo electric cylinder 605 is rotatably connected to the moving shaft 603;

[0082] The telescopic rod of the servo electric cylinder 605 can move within the telescopic range with high precision, so as to control the rotating arm 602 to form different rotating states;

[0083] Release electric cylinders 607 are fixedly installed on both sides of the top end of the rotating arm 602. The bottom end of the telescopic rod of the release electric cylinder 607 is fixedly connected to a pushing seat 608, and a release pushing sleeve 609 is fixedly connected to the bottom surface of the pushing seat 608;

[0084] Safety card sleeves 606 are also fixedly connected in pairs to the top end of the rotating arm 602;

[0085] And after the water bath tank 202 stops rotating to the position where the top end is parallel to the top surface of the main housing 101, the parallelogram structure formed by the main connecting rod 303 and the connecting link 304 can just be rotated to form a rectangular structure;

[0086] And when the water bath tank 202 stops rotating to the position where the top end is parallel to the top surface of the main housing 101, after the parallelogram structure formed by the main connecting rod 303 and the connecting link 304 is synchronously rotated to form a rectangular structure, with the upward rotation movement of the rotating arm 602, the safety card sleeve 606 can be inserted into the connecting arm of the auxiliary fixing frame 401, so that after the rotating arm 602 is rotated to the position where the pushing seat 608 is parallel to the top surface of the main housing 101, through the clamping fit formed by the safety card sleeve 606 and the auxiliary fixing frame 401, the stability of the rectangular structure formed by the main connecting rod 303 and the connecting link 304 is improved;

[0087] After the rotating arm 602 rotates to a position where the pushing seat 608 is parallel to the top surface of the main housing 101, when the position of the releasing sleeve 609 is exactly opposite to the position of the pushing hole 509 opened in the main body of the placement rack 501, and after starting the releasing electric cylinder 607 to drive the pushing seat 608 and the releasing sleeve 609 to move downward, the inner hole of the releasing sleeve 609 can be sleeved on the outer surface of the conical insertion post 507 extending into the pushing hole 509. As the releasing sleeve 609 continues to move downward, it can drive the conical insertion post 507 to form an inward contraction action. After the conical insertion post 507 contracts, the clamping fit formed by the conical insertion post 507 and the conical socket 508 fails, and at this moment, there is enough clearance between the bottom end of the pushing seat 608 and the top end of the placement rack 501, and the placement rack 501 can be moved upward relative to the main connecting rod 303 by a certain distance. After the releasing sleeve 609 retracts and the rotating arm 602 rotates outward to a position where it does not interfere with the removal of the placement rack 501, the placement rack 501 carrying the EP tube 506 can be quickly taken out from the water bath 202;

[0088] The paired U-shaped sliding seats 701 are fixedly connected to the top end of the rotating arm 602. The two sides of the bottom end of the U-shaped sliding seat 701 are both slidably connected with insertion columns 702, and the insertion column side plates 703 are fixedly connected between the outer sides of the insertion columns 702;

[0089] One side of each group of pushing seats 608 is fixedly connected with a pushing inclined block 707. One side of the insertion column side plate 703 is fixedly connected with a pair of passive inclined blocks 706 in a paired manner, and the position of the pushing inclined block 707 on the same side is opposite to the passive inclined block 706;

[0090] The socket 704 is inserted and fixed in the middle of the insertion column 702. A compression spring 705 is sleeved and installed in each group of insertion columns 702. One side of the compression spring 705 is clamped with the socket 704, and the other side is clamped with the bottom end of a group of U-shaped sliding seats 701 at the inner end of the top head of the rotating arm 602;

[0091] Under the supporting elastic force of the compression spring 705, when there is no external force to push the insertion column side plate 703, the socket 704 is clamped with the bottom end of a group of U-shaped sliding seats 701 at the outer end of the top head of the rotating arm 602, and the passive inclined block 706 is at the limit position of outward movement;

[0092] After the rotating arm 602 rotates to a position where the pushing seat 608 is parallel to the top surface of the main housing 101, the insertion column 702 is horizontally located at a position opposite to the outward moving socket 510. As the releasing electric cylinder 607 drives the pushing seat 608 and the releasing sleeve 609 to move downward, after the pushing seat 608 moves downward to a certain position, the pushing inclined block 707 and the passive inclined block 706 will form a sliding tangential fit, and during the continuous downward movement of the pushing seat 608 and the releasing sleeve 609, the insertion column 702 can be pushed into the outward moving socket 510;

[0093] And after the release push sleeve 609 is pushed downward to a position where the conical plug post 507 can be safely pushed to disengage from the conical socket 508, the plug post 702 has been inserted into the outwardly displaced socket 510 in place;

[0094] At this moment, when the release push sleeve 609 passes through the push hole 509 and is in a state of inwardly squeezing the conical plug post 507, the conical plug post 507 disengages from the conical socket 508. During the process of the rotating arm 602 automatically rotating outward to drive the plug post 702 to move, the conical socket 508 will not interfere with the conical plug post 507, and the placement rack 501 carrying the EP tube 506 will be taken out of the water bath 202 by using the plug-in fit formed by the plug post 702 and the outwardly displaced socket 510. Due to the elastic deformation of the conical plug post 507 itself, during this process, the release push sleeve 609 and the conical plug post 507 can be safely disengaged;

[0095] And there is a certain fit clearance between the arc-shaped socket 502 and the arc-shaped slot 503, allowing the rotating arm 602 to automatically rotate outward at this time to disengage the placement rack 501 from the main connecting rod 303 through the plug-in fit formed by the plug post 702 and the outwardly displaced socket 510, and safely take it out of the water bath 202, reducing the risk of scalding during the operation.
