Description

Technical Field

[0001] The present invention relates to the technical field of transfer devices, and in particular to a specimen transfer device. Background Art

[0002] A specimen usually refers to a physical object or sample used for research, analysis or display. In scientific fields such as medicine, biology and chemistry, specimens mainly refer to biological tissues, cells, body fluids, such as blood, urine, tissue sections, etc. used for experiments and research.

[0003] A Chinese patent with authorization announcement number CN222572926U discloses a specimen tube transport device, which aims to solve the problem in related technologies that specimens in the specimen tubes are easily disturbed by external temperature fluctuations due to the fully open storage and retrieval process when entering and exiting the warehouse or sorting, thereby affecting the activity of the samples. The transport device includes: a storage cabinet, a pick-and-place mechanism, and a refrigeration element. The storage chamber in the storage cabinet is used for cold storage of specimen tubes, the refrigeration element is used for refrigeration, and the pick-and-place mechanism is used to clamp the specimen tubes into the storage chamber. The transport device realizes the closed storage and placement of specimen tubes through the pick-and-place mechanism set in the closed transport vehicle, reduces the time that the specimen tubes are exposed to the external environment, and reduces the risk of sample inactivation due to external temperature fluctuations. It overcomes the problem that the specimen tube samples in the existing specimen tube transport vehicles are easily disturbed by external temperature fluctuations due to the fully open storage and retrieval process, thereby affecting the activity of the samples.

[0004] In the medical testing process, after the specimens are collected, they need to be sent to the laboratory for analysis with the help of a transfer device. Some specimens also need to be placed in a special storage box to maintain their stability, and then transported by the transfer device. Usually, this specimen transportation work is undertaken by female nurses. When the transfer device needs to transport specimens in batches, due to the weight of the device itself plus the load of the specimens and the storage box, nurses often need to exert a large thrust to push it to start. This situation undoubtedly increases the workload of nurses and is not conducive to their efficient work. Summary of the invention

[0005] The present invention provides a specimen transport device, aiming to solve the technical problem in the related art that when a transport device needs to transport specimens in batches, due to the weight of the device itself plus the load of the specimens, a nurse is often required to apply a large thrust to push it to start, which increases the workload of the nurses and is not conducive to their efficient and smooth work.

[0006] A specimen transfer device of the present invention includes: a base, moving wheels, and a push handle rotatably mounted on the base. A bearing plate is vertically and elastically slidably mounted on the base, and a boosting module is further provided on the base. The boosting module includes a power storage unit, a control unit, and a locking unit. The power storage unit includes an outer cylinder provided on the base. A rotating rod is rotatably mounted in the outer cylinder. A power storage member is provided between the rotating rod and the outer cylinder. A ratchet gear is provided on the rotating rod. A mounting seat is vertically and elastically slidably mounted on the base. A power storage wheel is provided at the bottom of the mounting seat. A driving shaft drivingly connected to the rotating rod is rotatably mounted on the power storage wheel through a one-way structure. The control unit includes a push plate horizontally and elastically slidable left and right on the base. The push plate is in driving cooperation with the push handle. A clamping plate is also horizontally and elastically slidable left and right on the base. A first ratchet tooth meshing with the ratchet gear is provided on the clamping plate. A driving assembly is provided on the push plate so that the power storage wheel can descend when the push plate moves rightward and ascend when it moves leftward. The locking unit includes a locking assembly slidably mounted back and forth on the base for restricting the rightward sliding of the push plate. The locking assembly is connected to the bearing plate through a connecting rod, and the sliding of the locking assembly is controlled by the lifting of the bearing plate.

[0007] Beneficial effects: After placing the specimen on the bearing plate, due to the action of gravity, the bearing plate will descend, thereby driving the two ratchet blocks to move away from each other through the connecting rod, releasing the restriction on the push plate, and enabling the push plate to slide to the right. Then, push the push handle to the right. The push plate pushes the clamping plate to move to the right. The first ratchet tooth disengages from the ratchet gear, and the elastic force of the power storage member is released. The rotating rod drives the driving sprocket to rotate clockwise. The driving sprocket drives the driven sprocket to rotate clockwise. The driven sprocket drives the power storage wheel to rotate clockwise through the driving shaft. The clockwise rotation of the power storage wheel can assist the base to move forward. When pulling the device back after unloading the specimen, the power storage wheel rotates counterclockwise. At this time, the power storage wheel can drive the driving shaft to rotate counterclockwise synchronously. The driven sprocket drives the driving sprocket to rotate, so that the rotating rod rotates counterclockwise to store energy for the power storage member. When pushing the device, through the release of the elastic force of the power storage member, the power storage wheel is driven to rotate. The power storage wheel can give an auxiliary force for the device to move forward, so that it is relatively easy to push the device to start, effectively saving manpower. When pulling the device back, the reverse rotation of the power storage wheel can store energy for the power storage member again. When loading a large number of heavy specimens, the nurse can still easily push the device forward, making the device highly practical and improving work efficiency.

[0008] Preferably, a revolution counter is provided on the rotating rod, and an alarm is further provided on the base. The alarm is electrically connected to the revolution counter.

[0009] The effect is that the revolution counter enables the device to accurately detect the energy storage state of the power storage member when moving. When the power storage member finishes storing energy, it timely reminds the worker to lift the power storage wheel.

[0010] Preferably, the driving assembly includes a driving plate disposed on the pushing plate. A through hole is formed in the mounting seat and extends through the front and rear. The bottom of the through hole has an inclined section and a horizontal section, which are connected. The inclined section gradually rises from left to right. The driving plate penetrates into the through hole and abuts against the inclined section or the horizontal section.

[0011] The effect is that the driving plate can be driven by the pushing plate to move left and right, completing the lifting and lowering of the energy storage wheel.

[0012] Preferably, the locking assembly includes a ratchet block slidably mounted on the base in the front and rear directions. A second ratchet tooth engaged with the ratchet block is provided on the pushing plate. One end of the connecting rod is rotatably connected to the ratchet block, and the other end is rotatably fitted with the bearing plate.

[0013] The effect is that it can limit the rightward sliding of the pushing plate, thereby preventing the pushing plate from pushing the clamping plate to slide rightward and preventing the energy storage member from being released.

[0014] Preferably, a telescopic rod is fixedly mounted on the base, and the telescopic part of the telescopic rod is fixedly connected to the ratchet block.

[0015] Preferably, a gear fixedly connected to the push handle is rotatably mounted on the base, and a rack engaged with the gear is fixedly mounted on the pushing plate.

[0016] The effect is that by pushing the push handle to rotate left and right, the pushing plate is driven to slide left and right, facilitating the control of the release of the energy storage member and the lifting of the energy storage wheel.

[0017] Preferably, a support column is vertically slidably mounted on the base. A plurality of horizontally arranged bearing plates are fixedly mounted on the support column in the vertical direction. A plurality of sliding seats are fixedly mounted on the bottom of the lowermost bearing plate, and the sliding seats are vertically elastically slidably fitted with the base.

[0018] Preferably, a driving sprocket is fixedly mounted on the rotating rod, a driven sprocket is fixedly mounted on the driving shaft, and the driving sprocket and the driven sprocket are connected by a chain drive.

[0019] Preferably, the energy storage wheel is a volute spring fixedly mounted in the outer cylinder, and the other end of the volute spring is fixedly connected to the rotating rod.

[0020] Preferably, a mounting tube is fixedly mounted on the base, and the clamping plate is elastically slidably fitted in the mounting tube in the left-right direction.

[0021] With the above technical solution, the beneficial effects of the present invention are as follows: After the specimen is placed on the bearing plate, due to the action of gravity, the bearing plate will descend, thereby driving the two ratchet blocks away from each other through the connecting rod, releasing the restriction on the pushing plate, and enabling the pushing plate to slide to the right. Then, push the pusher to the right, and the pushing plate pushes the clamping plate to move to the right. The first ratchet tooth disengages from the ratchet gear, and the elastic force of the energy storage member is released. The driving sprocket is driven to rotate clockwise through the rotating rod. The driving sprocket drives the driven sprocket to rotate clockwise. The driven sprocket drives the energy storage wheel to rotate clockwise through the driving shaft. The clockwise rotation of the energy storage wheel can assist the base to move forward. When the specimen is unloaded and the device is pulled back, the energy storage wheel rotates counterclockwise. At this time, the energy storage wheel can drive the driving shaft to rotate counterclockwise synchronously. The driven sprocket drives the driving sprocket to rotate, so that the rotating rod rotates counterclockwise to store energy for the energy storage member. When the device is pushed, the elastic force of the energy storage member is released to drive the energy storage wheel to rotate. The energy storage wheel can give the device an auxiliary force to move forward, so that it is relatively easy to push the device to start, which can effectively save manpower. When the device is pulled back, the energy storage wheel rotates in the reverse direction and can store energy for the energy storage member. When loading a large number of heavy specimens, the nurse can still easily push the device forward, making the device highly practical and improving work efficiency.

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0036] As Figures 1 to 12 shown, a specific embodiment of a specimen transporting device of the present invention includes a transporting module, a bearing module, and an assisting module.

[0037] As Figure 1 shown, the transporting module includes a base 10, moving wheels 11, side plates 12, and a pusher 13.

[0038] The interior of the base 10 is a hollow structure, and the shape of the base 10 is rectangular. In this embodiment, the length direction of the base 10 is defined as the left-right direction, and the width direction of the base 10 is defined as the front-back direction. Four moving wheels 11 are provided at the bottom of the base 10, and the four moving wheels 11 are respectively arranged at the four corners of the base 10. Among them, the two moving wheels 11 on the left side are universal wheels, that is, the left side of the base 10 is the pushing side, and the base 10 can be pushed to move and turn.

[0039] On the left side of the base 10, a side plate 12 is fixedly installed. The interior of the side plate 12 is a hollow structure, and the side plate 12 communicates with the bottom of the base 10. A pusher 13 is rotatably installed on the side plate 12, and the pusher 13 can rotate about an axis extending in the front-rear direction. The pusher 13 has an inverted U-shaped structure. The pusher 13 has a horizontal rod portion and two vertical rod portions. The axis of the horizontal rod portion extends in the front-rear direction. The front and rear ends of the horizontal rod portion are respectively fixedly connected to the two vertical rod portions. Both of the two vertical rod portions are vertically arranged, and the lower ends of the two vertical rod portions are respectively rotatably connected to the front and rear sides of the side plate 12. A worker's hand can hold the horizontal rod portion, so as to push the base 10 to move through the pusher 13.

[0040] As Figure 1 , Figure 5 As shown in FIGS. 7 and, the carrying module includes a support column 20, a carrying plate 21, a sliding seat 22, a first spring 23 and a fixed cylinder 24.

[0041] Four support columns 20 are provided, and the axes of the support columns 20 are all vertically arranged. The four support columns 20 are respectively arranged at positions near the four corners on the upper surface of the base 10, and the support columns 20 are slidably matched with the top wall of the base 10. That is, the lower ends of the support columns 20 penetrate into the interior of the base 10.

[0042] A plurality of carrying plates 21 are fixedly installed on the support columns 20. The carrying plates 21 are horizontally arranged, and the four support columns 20 vertically penetrate through all the carrying plates 21. A specimen piece can be placed on the upper surface of each carrying plate 21. In this embodiment, the number of the carrying plates 21 is 3. In other embodiments, the number of the carrying plates 21 can also be 2, 4 or even more. At positions corresponding to each layer of the carrying plate 21 on the support columns 20, enclosures are provided to enclose the four sides of the carrying plate 21 to prevent the specimen pieces placed on the carrying plate 21 from falling.

[0043] Four sliding seats 22 are fixedly installed at the bottom of the lowermost carrying plate 21. The sliding seats 22 are columnar structures, and their axes extend in the vertical direction. The sliding seats 22 are arranged in two rows at intervals in the front-rear direction, and two are arranged at intervals in the left-right direction in each row. A first spring 23 is fixedly connected to the bottom of each sliding seat 22.

[0044] Four fixing cylinders 24 are fixedly installed inside the base 10. The fixing cylinders 24 correspond to the four sliding seats 22 one by one. The fixing cylinder 24 is of a structure with a hollow interior and an upper opening, and openings penetrating up and down are provided at the corresponding positions on the upper surface of the base 10. The fixing cylinder 24 passes upward through the opening and extends above the base 10. The four sliding seats 22 are respectively slidably assembled up and down in the fixing cylinder 24, and one end of the first spring 23 away from the sliding seat 22 is fixedly connected inside the fixing cylinder 24. When a certain number of specimen pieces are placed on the bearing plate 21, the bearing plate 21 is subjected to a downward gravity, which will cause the sliding seat 22 to slide downward along the fixing cylinder 24, and the first spring 23 will be compressed.

[0045] The boosting module includes a power storage unit, a control unit, and a locking unit. The power storage unit can store or release power to assist the base 10 to move forward when the base 10 moves, reducing the magnitude of the worker's thrust. The control unit can control the release of the power storage unit, and the locking unit is used to lock the control unit so that the control unit can work only when a certain amount of specimen pieces are placed on the bearing module.

[0046] As Figure 6 、 Figure 7 、 Figure 8 And Figure 9 As shown in

[0047] Two outer cylinders 30 are fixedly installed inside the base 10. The two outer cylinders 30 are coaxially arranged, and the axis of the outer cylinder 30 extends in the front-rear direction. The two outer cylinders 30 are symmetrically arranged front and rear. That is, the front outer cylinder 30 is fixedly installed on the front side wall of the base 10, and the rear outer cylinder 30 is fixedly installed on the rear side wall of the base 10. One end of the two outer cylinders 30 facing each other is of an open structure.

[0048] A rotating rod 31 is rotatably installed inside the outer cylinder 30. The rotating rod 31 is coaxially arranged with the outer cylinder 30. The two ends of the rotating rod 31 respectively penetrate into the front and rear outer cylinders 30. That is, the rear end of the rotating rod 31 is rotatably matched with the rear outer cylinder 30, and the front end of the rotating rod 31 is rotatably matched with the front outer cylinder 30.

[0049] A power storage member 32 is fixedly connected inside both outer cylinders 30. In this embodiment, the power storage member 32 is a volute spring, and one end of the volute spring is fixedly connected to the outer cylinder 30, and the other end of the volute spring is fixedly connected to the rotating rod 31.

[0050] In this embodiment, when the elastic force of the volute spring is released, the rotating rod 31 rotates clockwise, and when the rotating rod 31 rotates counterclockwise, the volute spring can be charged.

[0051] Two driving sprockets 35 are fixedly installed on the rotating rod 31 at intervals in the front and rear directions, and both of the two driving sprockets 35 are located inside the two outer cylinders 30. The two driving sprockets 35 are coaxially arranged with the rotating rod 31.

[0052] A revolution counter 33 is fixedly installed on the rotating rod 31. The revolution counter 33 is used to detect the number of revolutions of the rotating rod 31. An alarm (not shown in the figure) is also fixedly installed inside the base 10. When the rotating rod 31 rotates counterclockwise, the revolution counter 33 can detect the number of revolutions of the rotating rod 31 in real time, so as to ensure that when the energy storage of the scroll spring reaches the limit, the alarm will sound an alarm, and the energy storage of the scroll spring can be stopped in time, which will be described in detail later.

[0053] A ratchet gear 34 is also fixedly installed on the rotating rod 31. The ratchet gear 34 is coaxially arranged with the rotating rod 31, and the ratchet gear 34 is located at the middle position of the rotating rod 31.

[0054] Two mounting seats 40 are slidably installed up and down at the bottom of the base 10. The upper ends of the mounting seats 40 extend into the base 10, and the lower ends of the mounting seats 40 extend below the base 10. The two mounting seats 40 are arranged at intervals in the front and rear directions. Second springs 41 are fixedly installed on the upper surfaces of the two mounting seats 40. One end of the second spring 41 away from the mounting seat 40 is fixedly connected to the base 10. The second spring 41 can provide a restoring elastic force for the mounting seat 40. It should be particularly emphasized that the front and rear mounting seats 40 respectively correspond to the outer cylinders 30.

[0055] Energy storage wheels 42 are installed at the bottoms of the mounting seats 40. The energy storage wheels 42 can rotate along the axis extending in the front and rear directions. The front and rear energy storage wheels 42 are connected by a drive shaft 43. That is, the front and rear ends of the drive shaft 43 respectively pass through the two energy storage wheels 42, and the drive shaft 43 is rotationally matched with the energy storage wheels 42 through a one-way structure. It should be particularly emphasized that in this embodiment, the one-way structure is a ratchet structure (as Figure 12 shown). In other embodiments, the one-way structure can also be a bidirectional reversible one-way bearing. The one-way structure includes an outer ring 80, an inner shaft 81 and a pawl 82. The inner shaft 81 is rotatably installed inside the outer ring 80. The pawl 82 is rotatably installed on the inner shaft 81 through a torsion spring. A ratchet groove is provided inside the outer ring 80. One end of the pawl 82 abuts against the ratchet groove. The inner shaft 81 is coaxially and fixedly connected with the drive shaft 43, and the outer ring 80 is coaxially and fixedly connected with the energy storage wheel 42.

[0056] Two driven sprockets 44 are fixedly installed on the drive shaft 43. The two driven sprockets 44 are arranged at intervals in the front and rear directions, and both of the two driven sprockets 44 are coaxially arranged with the drive shaft 43. The two driven sprockets 44 respectively correspond to the two driving sprockets 35 one by one. That is, the front driven sprocket 44 corresponds to the front driving sprocket 35, and the rear driven sprocket 44 corresponds to the rear driving sprocket 35.

[0057] There are two vertically penetrating avoidance long holes provided at the bottom of the base 10. The two avoidance long holes are arranged at intervals in the front and back, and the two avoidance long holes respectively correspond to the front and rear driven sprockets 44.

[0058] The driving sprocket 35 and the driven sprocket 44 are drivingly connected by a chain 36. The chain 36 passes through the avoidance long holes, so that the driving sprocket 35 and the driven sprocket 44 can drive each other.

[0059] It should be specifically noted that the device moves forward by pushing the push handle 13. After unloading is completed, the device is pulled back to its original position by pulling the push handle 13.

[0060] When the elastic force of the energy storage member 32 is released, the driving sprocket 35 is driven by the rotating rod 31 to rotate clockwise. The driving sprocket 35 drives the driven sprocket 44 to rotate clockwise. The driven sprocket 44 drives the energy storage wheel 42 to rotate clockwise through the drive shaft 43. When the energy storage wheel 42 rotates clockwise, the base 10 can move forward. After the elastic force of the energy storage member 32 is completely released, the drive shaft 43 can no longer drive the energy storage wheel 42 to rotate. However, the device still needs to continue moving forward to the destination. Therefore, the energy storage wheel 42 will continue to rotate clockwise until the device reaches the end position. At this time, the energy storage wheel 42 continues to rotate clockwise, and the drive shaft 43 stops rotating. The reason is that: since the energy storage wheel 42 and the drive shaft 43 are connected by a one-way structure, according to the principle of the one-way rotation structure, when the drive shaft 43 is used as the drive source, the drive shaft 43 drives the inner shaft 81 to rotate clockwise. When the inner shaft 81 rotates clockwise, the pawl 82 is engaged in the ratchet groove on the outer ring 80, so as to drive the outer ring 80 to rotate clockwise. The outer ring 80 can drive the energy storage wheel 42 to rotate clockwise; when the elastic force of the energy storage member 32 is released and the device continues to move, the energy storage wheel 42 rotates clockwise as the drive source. When the energy storage wheel 42 rotates clockwise, the outer ring 80 also rotates clockwise. At this time, the pawl 82 cannot be engaged with the ratchet groove on the outer ring 80, and the outer ring 80 cannot drive the inner shaft 81 to rotate, nor will it drive the drive shaft 43 to rotate, which can avoid continuously driving the energy storage member 32 to rotate and causing damage to it, and can also ensure that the device continues to move forward; similarly, when the device is pulled back, the energy storage wheel 42 rotates counterclockwise. At this time, the outer ring 80 can drive the inner shaft 81 to rotate counterclockwise together. The inner shaft 81 can drive the drive shaft 43 to rotate counterclockwise synchronously. The driven sprocket 44 drives the driving sprocket 35 to rotate, so that the rotating rod 31 rotates counterclockwise to store energy for the energy storage member 32. The number-of-turns counter 33 will detect the number of turns of the rotating rod 31. When the rotating rod 31 rotates to a certain value, it means that the energy storage of the energy storage member 32 reaches the maximum value, and the alarm will sound to give a reminder.

[0061] Such as Figure 9As shown, insertion holes 45 that penetrate through from front to back are formed in both of the two mounting bases 40. The bottom of the insertion hole 45 has an inclined section 46 and a horizontal section 47. The inclined section 46 and the horizontal section 47 are in communication with each other, and the inclined section 46 gradually rises from left to right.

[0062] As Figure 2 , Figure 3 , Figure 4 and Figure 7 shown, the control unit includes a gear 50, a push plate 51, a third spring 52, a rack 53, a mounting pipe 54, a fourth spring 55, a clamping plate 56, a first ratchet tooth 57, and a driving plate 60.

[0063] A gear 50 is rotatably mounted inside the side plate 12. The axis of the gear 50 extends in the front-rear direction. The front and rear ends of the gear 50 are respectively fixedly connected to the two vertical rod portions of the pusher 13. Thus, when the pusher 13 is rotated, the gear 50 can be driven to rotate. A push plate 51 is horizontally slidably mounted inside the base 10 in the left-right direction. The push plate 51 is connected to the base 10 through a third spring 52. That is, one end of the third spring 52 is fixedly connected to the push plate 51, and the other end of the third spring 52 is fixedly connected to the base 10. A rack 53 is fixedly mounted on the push plate 51. The rack 53 meshes with the gear 50. Thus, when the gear 50 rotates, the push plate 51 can be driven to slide in the left-right direction.

[0064] A mounting pipe 54 is fixedly mounted on the right side wall of the base 10. The left end of the mounting pipe 54 is of an open structure. A clamping plate 56 is horizontally slidably mounted inside the mounting pipe 54 in the left-right direction. The clamping plate 56 is connected to the mounting pipe 54 through a fourth spring 55. The fourth spring 55 can provide elastic force for the reset of the clamping plate 56. The right end of the push plate 51 abuts against the clamping plate 56. When the push plate 51 slides to the right, the clamping plate 56 can be pushed to move to the right.

[0065] A first ratchet tooth 57 is arranged on the left side of the clamping plate 56. The first ratchet tooth 57 meshes with the ratchet gear 34. The first ratchet tooth 57 can limit the clockwise rotation of the ratchet gear 34, and the counterclockwise rotation of the ratchet gear 34 is not affected. When the push plate 51 pushes the clamping plate 56 to move to the right, the first ratchet tooth 57 is disengaged from the ratchet gear 34, and the ratchet gear 34 is released from the restriction and can rotate clockwise.

[0066] As Figure 7 , Figure 9 and Figure 10As shown, drive plates 60 are fixedly installed on both the front and rear sides of the pushing plate 51. The length direction of the drive plates 60 extends in the front-rear direction, and the drive plates 60 are inserted into the jacks 45 on the corresponding mounting seats 40. When the drive plates 60 move to the horizontal section 47, the mounting seats 40 descend, and the energy storage wheels 42 contact the ground. When the drive plates 60 move to the inclined section 46, the mounting seats 40 rise, and the energy storage wheels 42 leave the ground.

[0067] As Figure 5 , Figure 7 and Figure 11 shown, the locking unit includes a mounting platform 70, a telescopic rod 71, a ratchet block 72, a second ratchet tooth 73, a connecting plate 74, and a connecting rod 75.

[0068] Mounting platforms 70 are provided on both the front and rear sides of the pushing plate 51 inside the base 10. Two telescopic rods 71 are fixedly installed on the opposite surfaces of the mounting platforms 70. The telescopic rods 71 are composed of rod bodies connected by two springs. Ratchet blocks 72 are fixedly installed on the telescopic parts of the telescopic rods 71. The front and rear ratchet blocks 72 are symmetrically arranged, and a row of ratchets is arranged on the ratchet blocks 72 in the left-right direction.

[0069] Second ratchet teeth 73 are provided at the corresponding positions on both the front and rear sides of the pushing plate 51 and are engaged with the ratchet blocks 72. When the second ratchet teeth 73 are engaged with the ratchet blocks 72, the rightward sliding of the pushing plate 51 can be restricted, but the leftward sliding of the pushing plate 51 is not affected.

[0070] Connecting rods 75 are rotatably installed on the upper surfaces of the front and rear ratchet blocks 72 and rotate about the axis extending in the left-right direction. A connecting plate 74 is provided at the bottom of the lowermost bearing plate 21, and the upper ends of the connecting rods 75 are rotatably fitted with the connecting plate 74. When a specimen is placed on the bearing plate 21, the bearing plate 21 will descend, thereby driving the two ratchet blocks 72 to move away from each other through the connecting rods 75, that is, the front ratchet block 72 slides forward, and the rear ratchet block 72 slides backward. Thus, the restriction on the pushing plate 51 is released, enabling the pushing plate 51 to slide to the right.

[0071] In the initial state, the push handle 13 is in a vertical state, the drive plate 60 is located on the horizontal section 47 in the socket 45, and the power storage wheel 42 is in contact with the ground. After the specimen is placed on the carrier plate 21, the carrier plate 21 will drop under the action of gravity, thereby driving the two ratchet blocks 72 away from each other through the connecting rod 75, releasing the restriction on the push plate 51, and allowing the push plate 51 to slide to the right. Then push the push handle 13 to the right, the push handle 13 will rotate to the right by a certain angle, and the gear 50 will rotate to drive the push plate 51 to slide to the right. The push plate 51 pushes the clamping plate 56 to move to the right, and the first ratchet tooth 57 disengages from the ratchet gear 34. The ratchet gear 34 is released from the restriction and can rotate clockwise. Then the elastic force of the force storage member 32 is released, and the driving sprocket 35 is driven to rotate clockwise through the rotating rod 31, and the driving sprocket 35 drives the driven sprocket 44 to rotate clockwise, and the driven sprocket 44 drives the force storage wheel 42 to rotate clockwise through the driving shaft 43. The clockwise rotation of the force storage wheel 42 can assist the base 10 to move forward, that is, the force storage wheel 42 will give the device a forward thrust to assist the device to start, until the elastic force of the force storage member 32 is released, and the driving shaft 43 can no longer drive the force storage wheel 42 to rotate, but the device still needs to continue to move forward to the destination, so the force storage wheel 42 will continue to rotate clockwise until the device reaches the end position, at which time, the force storage wheel 42 continues to rotate clockwise, and the driving shaft 43 no longer rotates.

[0072] When the specimen is removed and the device is pulled back, the force storage wheel 42 rotates counterclockwise. At this time, the force storage wheel 42 can drive the driving shaft 43 to rotate counterclockwise synchronously, and the driven sprocket 44 drives the active sprocket 35 to rotate, so that the rotating rod 31 rotates counterclockwise to store force for the force storage member 32. The circle counter 33 will detect the number of circles of the rotating rod 31. When the rotating rod 31 rotates to a certain value, it means that the force storage member 32 has reached the maximum value, and the alarm will sound an alarm reminder. Then, use your foot to support the base 10 and pull the push handle 13 to the left. The push handle 13 will rotate and tilt to the left at a certain angle. At the same time, the push plate 51 will also slide to the left for a certain distance (at this time, the device is in an unloaded state, the connecting plate 74 is raised, and the ratchet block 72 is engaged with the second ratchet tooth 73, so the push plate 51 will not rebound to the right). The drive plate 60 moves to the left to above the inclined section 46, and the second spring 41 drives the mounting seat 40 to rise, so that the power storage wheel 42 leaves the ground, and then continues to pull the device back to its original position.

[0073] When it is used again, the specimen is placed on the supporting plate 21, the ratchet block 72 disengages from the second ratchet tooth 73, and the elastic force of the third spring 52 drives the push plate 51 to move to the right, so that the push handle 13 returns to the vertical state. At the same time, the driving plate 60 reaches the horizontal section 47 along the inclined section 46, drives the mounting seat 40 to descend, and the power storage wheel 42 contacts the ground again. It is the same as the above principle and can be used. It is particularly emphasized that the elastic force of the fourth spring 55 is greater than the elastic force of the second spring 41.

[0074] The working principle of the present invention is as follows: in the initial state, the push handle 13 is in a vertical state, the drive plate 60 is located on the horizontal section 47 in the socket 45, and the power storage wheel 42 is in contact with the ground. After the specimen is placed on the carrier plate 21, the carrier plate 21 will drop under the action of gravity, thereby driving the two ratchet blocks 72 away from each other through the connecting rod 75, releasing the restriction on the push plate 51, and allowing the push plate 51 to slide to the right. Then push the push handle 13 to the right, the push handle 13 will rotate to the right by a certain angle, and the gear 50 will rotate to drive the push plate 51 to slide to the right. The push plate 51 pushes the clamping plate 56 to the right and moves to the right. The first ratchet tooth 57 disengages from the ratchet gear 34, and the ratchet gear 34 is released from the restriction and can rotate clockwise. Then the elastic force of the force storage member 32 is released, and the driving sprocket 35 is driven to rotate clockwise through the rotating rod 31, and the driving sprocket 35 drives the driven sprocket 44 to rotate clockwise, and the driven sprocket 44 drives the force storage wheel 42 to rotate clockwise through the driving shaft 43. The clockwise rotation of the force storage wheel 42 can assist the base 10 to move forward, that is, the force storage wheel 42 will give the device a forward thrust to assist the device to start, until the elastic force of the force storage member 32 is released, and the driving shaft 43 can no longer drive the force storage wheel 42 to rotate, but the device still needs to continue to move forward to the destination, so the force storage wheel 42 will continue to rotate clockwise until the device reaches the end position, at which time, the force storage wheel 42 continues to rotate clockwise, and the driving shaft 43 no longer rotates. When the specimen is removed and the device is pulled back, the power storage wheel 42 rotates counterclockwise. At this time, the power storage wheel 42 can drive the drive shaft 43 to rotate counterclockwise synchronously, and the driven sprocket 44 drives the active sprocket 35 to rotate, so that the rotating rod 31 rotates counterclockwise to store power for the power storage member 32. The circle counter 33 will detect the number of circles of the rotating rod 31. When the rotating rod 31 rotates to a certain value, it means that the power storage member 32 has reached the maximum value, and the alarm will sound an alarm. Then use your feet to support the base 10 and pull the push handle 13 to the left. The push handle 13 will rotate and tilt to the left at a certain angle. At the same time, the push plate 51 also slides to the left for a certain distance. The driving plate 60 moves to the left to the top of the inclined section 46. The second spring 41 drives the mounting seat 40 to rise, so that the power storage wheel 42 leaves the ground, and then the device continues to be pulled back to the original position. When it is used again, the specimen is placed on the supporting plate 21, the ratchet block 72 disengages from the second ratchet tooth 73, and the elastic force of the third spring 52 drives the push plate 51 to move to the right, so that the push handle 13 returns to the vertical state. At the same time, the driving plate 60 reaches the horizontal section 47 along the inclined section 46, drives the mounting seat 40 to descend, and the power storage wheel 42 contacts the ground again, and it can be used in the same way as the above principle.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
