[0058] Referring to Figures 1 to 9 The utility model discloses an experimental carrier clamping device, experimental carrier clamping device includes the top 100, the jaw subassembly 200 and transmission assembly 300, and at least one group of oblique opposite angle of top 100 is provided with a jaw subassembly 200, and at least one of two jaw subassembly 200 on the oblique opposite angle can move relative to top 100, transmission assembly 300 is rotationally connected to top 100, and drive sliding slot 311 is provided on transmission assembly 300, and one end of jaw subassembly 200 is slid in drive sliding slot 311, wherein, the transmission assembly 300 can be operated to move, and one end of jaw subassembly 200 arranged in drive sliding slot 311 can move relative to drive sliding slot 311 to push jaw subassembly 200 to move relative to top 100 to hold experimental carrier.

[0059] The embodiment provides a test carrier clamping device, which is applied to the oscillation equipment 800 and used for clamping a test carrier, for example, a microtiter plate. By arranging one clamping jaw assembly 200 on at least one set of diagonally opposite corners of the top cover 100, at least one of the clamping jaw assemblies 200 arranged on the diagonally opposite corners is movable relative to the top cover 100, so that the distance between the clamping jaw assemblies 200 arranged on the diagonally opposite corners can be adjusted, so that the clamping jaw assemblies 200 can be switched between a clamping state and a releasing state, and then the clamping and releasing of the test carrier are realized. By rotating the transmission assembly 300 on the top cover 100, and arranging the driving sliding groove 311 on the transmission assembly 300, and sliding one end of the clamping jaw assembly 200 in the driving sliding groove 311, when the transmission assembly 300 is manually and operably rotated, the end of the clamping jaw assembly 200 is subjected to a force applied by the groove wall of the driving sliding groove 311, so that the clamping jaw assembly 200 is pushed to move relative to the top cover 100, so that the distance between the oppositely arranged clamping jaw assemblies 200 is increased or decreased, so that the test carrier can be placed between the clamping jaw assemblies 200 and clamped by the clamping jaw assemblies 200. By the above structure, the clamping and dismounting of the microtiter plate are more convenient, so that the work efficiency is improved.

[0060] In the embodiment, the top cover 100 has a rectangular structure, the clamping jaw assemblies 200 can be arranged on two sets of diagonally opposite corners of the top cover 100, and at least one clamping jaw assembly 200 arranged on each set of diagonally opposite corners is movable relative to the top cover 100, so that the distance between the two clamping jaw assemblies 200 arranged on the opposite corners can be adjusted; or one clamping jaw assembly 200 can be arranged on each set of diagonally opposite corners of the top cover 100, and only one clamping jaw 230 is movable relative to the top cover 100. In this way, the distance between the two clamping jaw assemblies 200 arranged on the opposite corners is adjusted, so that the clamping and releasing of the test carrier are realized.

[0061] As shown in FIGS. 1, 2 and 3, Figures 2 to 3 and Figure 9 In one embodiment, the transmission assembly 300 includes a rotating piece 310 and a pushing block 320, the rotating piece 310 is rotationally connected to the top cover 100, and the driving sliding groove 311 is arranged on the rotating piece 310; the pushing block 320 is fixedly connected to the rotating piece 310; the top cover 100 is provided with a guide groove 120, one end of the pushing block 320 away from the rotating piece 310 extends out of the top cover 100, the pushing block 320 is operably pushed, and the rotating piece 310 is rotationally movable relative to the top cover 100.

[0062] Specifically, the rotating member 310 is substantially a disc structure, which is arranged in the accommodating cavity on the back of the top cover 100. The rotating member 310 is rotatably connected with the top cover 100 through a bearing, and the driving sliding slot 311 is arranged away from the center of the rotating member 310, and the distance between each position of the driving sliding slot 311 and the rotation center of the rotating member is not equal. The knob 320 is fixedly connected with the rotating member 310, and the end of the knob 320 away from the rotating member 310 is extended out of the top cover 100 from the guide slot 120 of the top cover 100, so that the knob 320 can be operated by the hand of a person to move relative to the guide slot 120, thereby driving the rotating member 310 to rotate relative to the top cover 100.

[0063] In another embodiment, the rotating member 310 can be a long connecting block rotatably connected with the top cover, and the driving blocks are fixedly connected with the two ends of the connecting block, and the driving sliding slot 311 is arranged on the driving blocks. The driving blocks are driven to rotate by the rotation of the connecting block relative to the top cover, so as to change the position of the end of the clamping block assembly relative to the rotation center, so as to move the clamping block assembly relative to the top cover.

[0064] In another embodiment, one clamping jaw assembly 200 is arranged on each of the obliquely opposite corners of the top cover 100, and the two clamping jaw assemblies 200 are both movable relative to the top cover 100. In this case, two driving sliding slots 311 are arranged on the rotating member 310, and the starting ends of the two driving sliding slots 311 are symmetrically arranged with the center of the rotating member 310 as the symmetric point, and the terminal ends of the two driving sliding slots 311 are arranged in directions away from each other.

[0065] As shown in Figure 2 and Figure 3 In one embodiment, the clamping jaw assembly 200 extends from the corner of the top cover 100 to the middle part of the top cover 100, and the line connecting the two ends of the driving sliding slot 311 forms an angle with the extension direction of the clamping jaw assembly 200.

[0066] It should be noted that the clamping jaw assembly 200 extends from the corner of the top cover 100 to the middle of the top cover. It can be understood that the extension direction of the clamping jaw assembly has two cases. One is that the clamping jaw assembly extends from the corner of the top cover to the center of the top cover, and the extension direction of the clamping jaw assembly passes the center of the top cover. In this case, the distance between each point on the driving sliding groove and the rotation center of the rotating member 310 is set in a gradual form. The other is that the clamping jaw assembly extends from the corner of the top cover to the middle of the top cover, but the extension direction of the clamping jaw assembly 200 deviates from the center of the top cover, the distance between any position of the driving sliding groove 311 and the rotation center of the rotating member 310 is gradual, and the line connecting the two ends of the driving sliding groove 311 is set in a form that forms an angle with the extension direction of the clamping jaw assembly 200, so that when the rotating member 310 rotates relative to the top cover 100, the driving sliding groove 311 can act on the end of the clamping jaw assembly 200 due to the different extension directions of the driving sliding groove 311 and the clamping jaw assembly 200. And because the distance between each position on the driving sliding groove 311 and the rotation center of the rotating member 310 is gradual, the distance between the point where the driving sliding groove 311 and the clamping jaw assembly 200 intersect and the center of the rotating member 310 changes when the rotating member 310 rotates, and the movement of the clamping jaw assembly 200 relative to the top cover 100 is pushed by the change of the distance. The driving sliding groove 311 can be a straight groove or an arc-shaped groove. As a preferred embodiment, the driving sliding groove 311 can be set as an arc-shaped groove with a certain arc, which can prevent the end of the clamping jaw assembly 200 from generating a dead point with the driving sliding groove 311, thereby improving the stability of the movement of the clamping jaw assembly 200 relative to the top cover 100.

[0067] As shown in Figure 7 and Figure 8 Specifically, the clamping jaw assembly 200 includes a clamping jaw base 210, a guide member 220 and a clamping jaw 230. The clamping jaw base 210 is slidably arranged on the top cover 100. The guide member 220 is fixedly connected to one end of the clamping jaw base 210 and is slidably arranged in the driving sliding groove 311. The clamping jaw is arranged on the clamping jaw base 210.

[0068] The clamping jaw base 210 is used to support the clamping jaw 230 and establish the connection between the clamping jaw 230 and the top cover 100. By fixedly connecting the guide member 220 to one end of the clamping jaw base 210 and slidably arranging the guide member 220 in the driving sliding groove 311, when the transmission assembly 300 rotates relative to the top cover 100, the groove wall of the driving sliding groove 311 can act on the guide member 220, so that the guide member 220 slides relative to the driving sliding groove 311, and at the same time, the groove wall of the driving sliding groove 311 can push the guide member 220 and the clamping jaw base 210 to move relative to the top cover 100.

[0069] Specifically, the clamping jaw 230 is in a cylindrical structure, and two clamping jaws 230 are arranged on each clamping jaw seat 210 at intervals, and when the clamping jaw 230 clamps the microtiter plate, the clamping jaw 230 can abut on two intersecting sides of the microtiter plate. In another embodiment, the clamping jaw 230 can also be in a block structure. In other embodiments, the clamping jaw 230 can also be one, and if only one clamping jaw 230 is arranged on one clamping jaw seat 210, the shape of the clamping jaw 230 should be arranged as a member with a right-angled notch matching the angle of the microtiter plate, and the right-angled notch on the clamping jaw 230 can just be clamped on the corner of the microtiter plate. As a preferred embodiment, the clamping jaw 230 is arranged in a cylindrical structure, so that the clamping jaw 230 is in line contact with the side of the microtiter plate, and the position accuracy of the clamping jaw 230 is lower, thereby facilitating the arrangement of the clamping jaw 230, and in addition, it is also beneficial to make the clamping jaw 230 suitable for different models of microtiter plates.

[0070] The top cover 100 is provided with an open-ended accommodation cavity, and the transmission assembly 300 is arranged in the accommodation cavity. The top cover 100 is provided with an accommodation notch at the corner where the clamping jaw assembly 200 is arranged, and one end of the clamping jaw seat 210 is just accommodated in the accommodation notch, and the clamping jaw seat 210 and the top cover 100 form a complete rectangular structure. Further, the side wall of the accommodation notch of the top cover 100 is arranged in a circular arc shape, and the end face of the clamping jaw seat 210 corresponding to the side wall of the accommodation notch is also arranged in a circular arc shape. In this way, the clamping jaw seat 210 can be limited, so that the clamping of the microtiter plate is more stable.

[0071] As shown in Figures 1 to 3 and Figure 7 and Figure 8 Further, the top cover 100 is provided with a guide chute 110. The clamping jaw seat 210 includes a seat body 211 and a guide block 212, and the clamping jaw 230 is fixedly connected to the seat body 211. The guide block 212 is connected to the side of the seat body 211 away from the clamping jaw 230, and one end of the guide block 212 extends away from the seat body 211. The guide block 212 is in guiding cooperation with the guide chute 110. The guide chute 110 extends from the corner of the top cover 100 to the middle part of the top cover 100, and the center of the top cover 100 deviates from the extension direction of the guide chute 110.

[0072] Specifically, the guide sliding groove 110 extends from the corner of the top cover to the middle part of the top cover 100 and passes the center of the top cover 100. Of course, the guide sliding groove 110 can also extend from the corner of the top cover to the middle part of the top cover 100, and the extension direction of the guide sliding groove 110 deviates from the center of the top cover 100. Regardless of which form the extension direction of the guide sliding groove 110 is, the distance between any position of the driving sliding groove 311 and the rotation center of the rotating member 310 is gradually changed, and the line connecting the two ends of the driving sliding groove 311 forms an angle with the extension direction of the clamping jaw assembly 200, so that the clamping jaw assembly can be driven to move relative to the top cover by the rotation of the rotating member 310. The seat body 211 is used to connect the clamping jaw 230 and the guide block 212, and is used to limit the side wall of the accommodating gap on the top cover 100, so as to limit the clamping jaw assembly 200, thereby ensuring the distance between the two opposite clamping jaw assemblies 200. The guide block 212 is a long plate structure, and a guide protrusion 2121 is arranged on the guide block 212, and the guide protrusion 2121 slides in the guide sliding groove 110. The guide member 220 is arranged at one end of the guide block 212 away from the seat body 211.

[0073] It can be understood that the guide member 220 includes a fixed rod and a guide sleeve, the fixed rod is fixedly connected to the guide block 212, and the guide sleeve is rotatably connected to the fixed rod and slidably connected to the driving sliding groove 311. By arranging in this way, it is beneficial to reduce the friction between the guide member 220 and the driving sliding groove 311, thereby reducing the wear of the guide sleeve, and in addition, it is also beneficial to make the movement of the clamping jaw seat 210 relative to the top cover 100 more stable and reliable.

[0074] Specifically, the guide block 212 and the guide protrusion 2121 form a cross section similar to a "convex" structure, and of course can also be a dovetail structure; correspondingly, the guide sliding groove 110 is a matching groove similar to a "convex" or dovetail type. In this embodiment, two spaced limiting blocks 130 are arranged on the top cover 100, and a limiting groove 131 is arranged on the limiting block 130, the limiting grooves 131 on the two limiting blocks 130 are oppositely arranged, and the gap between the two limiting grooves 131 and the two limiting blocks 130 defines the above-mentioned guide sliding groove 110.

[0075] As shown in Figure 2 and Figure 3 In one embodiment, the test carrier clamping device further includes a resilient member 400, one end of the resilient member 400 is connected to the top cover 100, and the other end of the resilient member 400 is connected to the transmission assembly 300, and the resilient member 400 provides a resilient force for the rotation of the transmission assembly 300.

[0076] Specifically, the elastic element 400 is a spring. A fixing post 410 is provided in the accommodating cavity of the top cover 100 near the lever 320. A fixing hole is provided on the rotating element 310. One end of the spring is sleeved on the fixing post 410, and the other end is hooked in the fixing hole. For example, when the lever is manually moved along... Figure 2 When the device moves to the right, the rotating member 310 rotates clockwise relative to the top cover 100. At this time, the guide member 220 moves away from the center of the rotating member 310 under the force of the groove wall of the drive slide 311, and the gripper seat 210 moves away from the center of the rotating member 310 along the guide slide 110. At this time, the distance between the two opposing gripper assemblies 200 increases, and the spring is stretched. When the lever 320 moves to its limit position, the distance between the two gripper assemblies 200 is the largest, and the micro-titer plate can be placed between the two grippers 230. When the force on the lever 320 is removed, the rotating member 310 rotates counterclockwise under the elastic restoring force of the spring. At this time, the gripper seat moves towards the center of the rotating member 310 under the drive of the drive slide 311. When the guide member 220 moves to the starting end of the drive slide 311, the distance between the two gripper assemblies 200 is the smallest, and the micro-titer plate is clamped. By providing the elastic element 400 as described above on the top cover 100, the elastic restoring force of the elastic element 400 pulls the rotating member 310 back to its original position, thereby switching the gripper assembly 200 from the released state to the gripping state. Furthermore, by providing the elastic element 400 as described above, without applying external force to the lever 320, the elastic element 400 applies a pulling force to the rotating member 310, keeping the gripper assembly 200 in the gripping state, thus ensuring the reliability of the micro-titer plate clamping.

[0077] In another embodiment, the elastic element 400 can be a torsion spring, which is sleeved on the rotating shaft for rotating the rotating element. One torsion arm of the torsion spring abuts against the rotating element, and the other torsion arm abuts against the cover plate. With this arrangement, the torsion spring can provide a restoring force for the return of the rotating element.

[0078] like Figure 4 and Figure 5 As shown, the test vehicle clamping device further includes at least one pair of magnetic attractors 500. One of the magnetic attractors 500 in each pair is connected to the top cover 100, and the other is connected to the transmission assembly 300. The two magnetic attractors 500 in each pair can be attracted to each other. By providing magnetic attractors 500 on the top cover 100 and the rotating member 310, the rotating member 310 is returned to its original position by being attracted to each other by the magnetic force on the magnetic attractors 500.

[0079] Specifically, the magnetic attraction member 500 is a magnet, two magnets are arranged on the rotating member 310, and the two magnets are symmetrically arranged with the center of the rotating member 310 as a symmetric point. Correspondingly, when the two jaw assemblies 200 are in the clamping state, magnets are arranged on the top cover 100 corresponding to the magnets on the rotating member 310. When the knob 320 is pushed and the magnetic attraction force of the magnetic attraction member 500 is overcome, the rotating member 310 rotates, and the two magnets move away from each other. When the force on the knob 320 is removed, the magnets arranged on the rotating member 310 and the magnets arranged on the top cover 100 attract each other, so that the rotating member 310 rotates, thereby realizing the return of the rotating member.

[0080] It can be understood that in some embodiments, only the elastic member 400 can be arranged to provide a restoring force for the return of the rotating member 310; in other embodiments, only the magnetic attraction member 500 can be arranged to provide a restoring force for the return of the rotating member 310; in the present embodiment, the elastic member 400 and the magnetic attraction member 500 can be arranged to provide a restoring force for the return of the rotating member 310. By arranging in this way, the reliability of the return of the rotating member 310 can be ensured, so that the reliability of the clamping state can be maintained.

[0081] As shown in Figure 3 In one embodiment, the test carrier clamping device further comprises a driving motor 610, a driving block 620 and a blocking member 630. The motor base of the driving motor 610 is fixedly connected to the top cover 100 or the base 810. The driving block 620 is fixedly connected to the output shaft of the driving motor 610, and extends along the radial direction of the output shaft. The blocking member 630 is fixedly connected to the rotating member 310. The driving block 620 is driven by the output shaft to rotate by a predetermined angle relative to the top cover 100, and the driving block 620 abuts against the blocking member 630 to push the rotating member 310 to rotate.

[0082] Specifically, the motor base of the driving motor 610 can be fixed on the top cover 100 or the base 810 of the oscillation device. The driving block 620 is connected to the output shaft of the driving motor 610, and the driving block 620 is driven by the driving motor 610 to rotate around the axis of the output shaft. The blocking member 630 is arranged on the rotating member 310, and when the driving block 620 abuts against the blocking member 630, the driving block 620 continues to rotate, thereby pushing the rotating member 310, so that the jaw seat 210 moves relative to the top cover 100. In this way, the automation degree of the movement of the jaw assembly 200 can be improved, thereby making the operation more convenient.

[0083] As shown in Figure 3As shown, in one of the embodiments, the test carrier clamping device further comprises a position detection member 700 arranged on the rotating member 310 and / or the base 810, and the position detection member 700 is capable of detecting whether the rotating member 310 reaches the preset position. By arranging the position detection member 700, when the rotating member 310 moves by the preset angle, the position detection member 700 can detect it, so that the driving motor 610 stops rotating, thereby preventing the rotating member 310 from rotating excessively and causing damage to the rotating member 310.

[0084] Specifically, the position detection member 700 comprises an inductive sensor 720 and a light shielding member 710, the light shielding member 710 is fixedly connected to the rotating member 310, and the inductive sensor 720 is fixedly connected to the base 810. The inductive sensor 720 is provided with a slot, when the rotating member 310 rotates and reaches the preset position, the light shielding member 710 can be inserted into the slot to shield the light in the slot, so that the inductive sensor 720 recognizes that the rotating member 310 reaches the preset position, and then the control unit controls the driving motor 610 to stop rotating. In this way, the safety and reliability of the test carrier clamping device are improved.

[0085] As shown in the drawings, Figure 1 The utility model discloses an embodiment further provides an oscillation equipment 800, and the oscillation equipment 800 comprises the test carrier clamping device as above. Specifically, the base 810 of the oscillation equipment 800 is provided with a rotating shaft, and the top cover 100 is fixedly connected to the rotating shaft. The top cover 100 rotates relative to the base 810 under the driving of the rotating shaft. The microtiter plate is clamped on the top cover 100 by the test carrier clamping device, so that the rotating shaft drives the top cover 100 to make circular motion relative to the base 810, and the microtiter plate is driven to make circular motion. By applying the test carrier clamping device as above to the oscillation equipment 800, the clamping and dismounting of the microtiter plate are more convenient, thereby facilitating the improvement of the work efficiency.

[0086] As shown in the drawings, Figure 5 In one of the embodiments, the top cover 100 is provided with a mounting hole 140 at the corner where the clamping jaw assembly 200 is not arranged, and the base 810 of the oscillation equipment is provided with a track groove. The oscillation equipment further comprises a guide sliding member 820, one end of the guide sliding member 820 is mounted in the mounting hole 140. The top cover 100 is rotationally connected to the base 810, and the other end of the guide sliding member 820 is slidably arranged in the track groove.

[0087] By arranging the guide sliding member 820 on the top cover and the track groove on the base 810, when the top cover rotates relative to the base, the guide sliding member and the track groove are matched to guide, so that the rotation of the top cover relative to the base is more stable.

[0088] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered as within the scope of the present disclosure.

[0089] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the scope of the present application. It should be noted that, for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
