Description

Technical Field

[0001] The present invention relates to the technical field of measurement, and particularly relates to an experimental rabbit body weight measurement device and a method thereof. Background Art

[0002] Experimental rabbits are bred by artificially raising and breeding domestic rabbits with clear genetic backgrounds and known origins, and controlling the microorganisms and parasites they carry. During the breeding process of experimental rabbits, it is necessary to regularly measure their body weights to facilitate breeders in collecting data on experimental rabbits.

[0003] When measuring the body weight of existing experimental rabbits, most of them directly place the experimental rabbits on a weighing scale, and then use the fixing component on the weighing scale to fix the experimental rabbits so as to measure the body weight of the experimental rabbits. Although this measurement method can measure the body weight of experimental rabbits, after the measurement, the fixing component needs to be untied again to measure the body weight of the next experimental rabbit. In this process, not only is the process cumbersome, but the measurement progress is very slow, increasing the extra workload for breeders. For this reason, we propose an experimental rabbit body weight measurement device and a method thereof. Summary of the Invention

[0004] To solve the technical problem of slow progress in measuring the body weight of experimental rabbits, the present invention provides an experimental rabbit body weight measurement device and a method thereof.

[0005] The present invention is implemented by the following technical solutions: An experimental rabbit body weight measurement device includes a frame body. A loading plate is fixed inside the frame body. Above the loading plate, there is a carrier plate that slides inside the frame body. Above the carrier plate, there is a loading frame. Inside the loading frame, there is a mounting plate rotatably connected. A fixing component is provided on the mounting plate. A pressure sensor is fixed on the top side of the loading plate. A loading groove is formed on the bottom side of the carrier plate. The sensing end of the pressure sensor is fixed with a force-bearing block that slides inside the loading groove. A display instrument electrically connected to the pressure sensor is fixed on the frame body. Through the cooperation of the force-bearing block, the pressure sensor 21, and the display instrument 6, the body weight of the experimental rabbit can be measured.

[0006] As a further improvement of the above solution, the fixing component includes fixing plates slidably arranged at both ends of the top side of the mounting plate. A sponge sheet is fixed inside the fixing plates. Rotating shafts rotatably connected to the inner wall of the loading frame are fixed at both ends of the mounting plate. A sliding groove is formed in the top side of the mounting plate. Sliders are slidably connected to both ends inside the sliding groove. A connecting block fixed to the slider is fixed on the fixing plate. The connecting block slides inside the notch of the sliding groove. Multiple sliding holes are formed in the slider. Multiple guide rods slidably penetrating into adjacent sliding holes are fixed inside the sliding groove. Multiple connecting springs sleeved outside the adjacent guide rods are fixed between the two sliders. A receiving groove is formed at one end of the carrier plate. A transfer column with the other end fixed to one end of the loading frame is rotatably connected inside the receiving groove. A support block abutted against the carrier plate is fixed to the bottom of the other end of the loading frame. A driving gear is fixed to the outer side of the transfer column. A rack plate meshed with the driving gear is arranged on one side of the driving gear. Multiple hydraulic cylinders with piston ends fixed to the rack plate are fixed on the carrier plate. Through the operation of the fixing component, the experimental rabbit to be measured can be fixed, preventing the experimental rabbit from jumping during the weight measurement process. Moreover, the experimental rabbit after weight measurement can be quickly discharged, avoiding repeatedly opening and closing the fixing component.

[0007] As a further improvement of the above solution, a support plate is arranged between the two fixing plates. Sliding grooves are formed at both ends of the support plate. Multiple slots are formed in the fixing plates and the sponge sheets. A sliding plate is slidably connected inside the sliding groove. One end of the sliding plate away from the support plate slides inside the adjacent slot. An assembly groove is formed at the end of the sliding plate located outside the fixing plate. A sliding block is slidably connected inside the assembly groove. Multiple pushing springs fixed to the sliding block are fixed to the inner wall of the assembly groove. A blocking block in contact with the adjacent fixing plate is fixed to the side of the sliding block away from the pushing spring. Through the cooperative operation of the support plate and the sliding plate, the experimental rabbit to be measured can be carried and protected, preventing the experimental rabbit from being injured during the fixing process. Moreover, the carrying component can be adaptively adjusted according to the body shape of the experimental rabbit.

[0008] As a further improvement of the above solution, the blocking block slides inside the notch of the adjacent assembly groove, and the depth of the assembly groove is greater than the length of the blocking block. The blocking block can be effectively received through the assembly groove with a depth greater than the length of the blocking block.

[0009] As a further improvement of the above solution, a handle is fixed to the outside of the fixing plate at one end of the loading frame. Anti-slip patterns are formed on the outer wall of the handle. Through the handle, the user can conveniently pull the fixing plate.

[0010] As a further improvement of the above scheme, positioning blocks are fixed at both ends of the mounting plate, and the frame is provided with positioning grooves that slide with the positioning blocks. The positioning blocks slide inside adjacent positioning grooves. The sliding cooperation between the positioning blocks and the positioning grooves can improve the stability of the mounting plate.

[0011] As a further improvement of the above solution, a snap-in groove is provided at one end of the loading frame, and a snap-in block that cooperates with the snap-in groove is fixed on the frame. Through the cooperation between the snap-in groove and the snap-in block, the stability of the loading frame after deflection can be improved.

[0012] As a further improvement of the above solution, a net bag is fixed to the bottom of the frame, and the length of the net bag is greater than the length of the mounting plate. The experimental rabbit can be supported by the net bag to prevent the experimental rabbit from being injured when sliding out of the fixing plate.

[0013] As a further improvement of the above solution, the slider is a rectangular block, the width of the slider is greater than the width of the slide groove, and a limiting block in contact with the loading frame is fixed on the carrier plate. The limiting block can improve the stability of the mounting plate.

[0014] A method for measuring the weight of an experimental rabbit comprises the following steps:

[0015] S1: Place the experimental rabbit whose weight needs to be measured between two fixed plates, and then measure the weight of the experimental rabbit through the cooperation of the pressure sensor and the display instrument;

[0016] S2: After the weight measurement of the experimental rabbit is completed, the fixing plate and the experimental rabbit can be driven to rotate by rotating the loading frame;

[0017] S3: When the experimental rabbit rotates to the bottom of the net bag, the mounting plate flips, driving the fixed plate and the experimental rabbit to flip. When the experimental rabbit falls onto the net bag, the experimental rabbit on the net bag can be taken out and placed in the breeding ground;

[0018] S4: When the experimental rabbit inside the fixing plate is separated from the fixing plate, the mounting plate is turned over and the loading frame is rotated until the fixing plate is reset;

[0019] S5: After the fixation plate is reset, repeat the above steps and continue to measure the weight of the remaining experimental rabbits.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention can help breeders to quickly measure the weight of experimental rabbits, and can restrain the measured experimental rabbits to prevent the experimental rabbits from jumping during the weight measurement process. The measurement accuracy is high, and the experimental rabbits after weight measurement can be quickly discharged, avoiding the need to open and close the restraining component back and forth, and the operation is simple.

[0022] 2. The present invention can carry and protect the measured experimental rabbits, avoid the experimental rabbits from being injured during the immobilization process, has high protection performance, and can adaptively adjust the carrying component according to the body shape of the experimental rabbits, which is convenient to use.

[0033] Next, in combination with the drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following described embodiments or technical features can form a new embodiment.

[0034] Embodiment 1:

[0035] Combined with Figures 1-3As shown in FIGS. 6 - 8, an experimental rabbit body weight measuring device includes a frame body 1. Inside the frame body 1, a loading plate 2 is fixedly installed. Above the loading plate 2, a carrier plate 3 that slides inside the frame body 1 is provided. Above the carrier plate 3, a loading frame 4 is provided. Inside the loading frame 4, a mounting plate 5 is rotatably connected. On the mounting plate 5, a fixing and restraining assembly is provided. On the top side of the loading plate 2, a pressure sensor 21 is fixedly installed. On the bottom side of the carrier plate 3, a loading groove is formed. The sensing end of the pressure sensor 21 is fixedly connected to a force - receiving block that slides inside the loading groove. On the frame body 1, a display instrument 6 electrically connected to the pressure sensor 21 is fixedly installed. The fixing and restraining assembly includes fixing plates 7 that slide at both ends of the top side of the mounting plate 5. Inside the fixing plates 7, sponge sheets 8 are fixedly installed. At both ends of the mounting plate 5, rotating shafts rotatably connected to the inner wall of the loading frame 4 are fixedly installed. On the top side of the mounting plate 5, a sliding groove 15 is formed. At both ends inside the sliding groove 15, sliding blocks 16 are slidably connected. On the fixing plates 7, connecting blocks fixedly installed on the sliding blocks 16 are provided. The connecting blocks slide inside the notch of the sliding groove 15. The sliding blocks 16 are provided with a plurality of sliding holes. Inside the sliding groove 15, a plurality of guide rods that slide through adjacent sliding holes are fixedly installed. Between the two sliding blocks 16, a plurality of connecting springs sleeved outside the adjacent guide rods are fixedly installed. At one end of the carrier plate 3, a receiving groove is formed. Inside the receiving groove, a transfer column with the other end fixedly connected to one end of the loading frame 4 is rotatably connected. At the bottom of the other end of the loading frame 4, a support block that abuts against the carrier plate 3 is fixedly installed. On the outer side of the transfer column, a driving gear 17 is fixedly installed. On one side of the driving gear 17, a rack plate 18 meshing with the driving gear 17 is provided. On the carrier plate 3, a plurality of hydraulic cylinders 19 with piston ends fixedly connected to the rack plate 18 are fixedly installed.

[0036] The implementation principle of the experimental rabbit weight measurement device in the embodiment of the present application is as follows: when the weight of the experimental rabbit needs to be measured, the two fixing plates 7 can be pulled to drive the two fixing plates 7 to move away from each other. When the distance between the two fixing plates 7 is large enough, the experimental rabbit can be placed between the two fixing plates 7. Then the two fixing plates 7 can be loosened. At this time, the two sliders 16 can be pulled to reset by the reset elasticity of the connecting spring, and the two fixing plates 7 are pulled to reset and move. When the sponge sheet 8 on the fixing plate 7 contacts the experimental rabbit, the experimental rabbit is secured between the two fixing plates 7. At this time, the experimental rabbit will press the mounting plate 5, The loading frame 4 and the carrier plate 3 are loaded. The carrier plate 3 under pressure at this time will press the force-bearing block. At this time, the pressure sensor 21 will detect the pressure on the force-bearing block. The pressure detected by the pressure sensor 21 will be transmitted to the display instrument 6. At this time, the pressure on the display instrument 6 can be displayed. Then, the data before and after the experimental rabbit is placed on the display instrument 6 are compared. The smaller data is subtracted from the larger data. At this time, the weight of the experimental rabbit can be obtained. After the weight of the experimental rabbit is obtained, the operation of the hydraulic cylinder 19 can be used to drive the piston end of the hydraulic cylinder 19 to move, drive the rack plate 18 to move, and drive the drive gear 17 to move. When the experimental rabbit is displaced from the carrier plate 3, the fixed plate 7 can be pushed to drive the fixed plate 7 to flip over. When the enclosure formed by the two fixed plates 7 faces downward, the experimental rabbit located between the two fixed plates 7 will break away from between the two fixed plates 7. At this time, the experimental rabbit breaks away from the restraining assembly, and then the fixed plate 7 can be flipped over to drive the fixed plate 7 to rotate. The fixed plate 7 is flipped, and when the enclosure opening formed by the two fixed plates 7 faces upward, the operation of the hydraulic cylinder 19 drives the piston end of the hydraulic cylinder 19 to move, drives the rack plate 18 to move, and drives the driving gear 17 to rotate. At this time, the rotating driving gear 17 will drive the adapter column to rotate, and then the rotating adapter column will drive the loading frame 4 to rotate, and then the rotating loading frame 4 will drive the mounting plate 5 to rotate, and drive the fixed plate 7 to rotate. When the fixed plate 7 is reset, the weight of the remaining experimental rabbits can be measured. It is easy to use and avoids opening and closing the restraint component back and forth. The operation is simple.

[0037] Example 2:

[0038] Combine Figure 4 and 5, on the basis of Embodiment 1, the further improvement of this embodiment lies in that: there is a support plate 9 between the two fixing plates 7. Both ends of the support plate 9 are provided with sliding grooves 10. The fixing plates 7 and the sponge sheet 8 are provided with a plurality of slots 12. A sliding plate 11 is slidably connected inside the sliding groove 10. One end of the sliding plate 11 away from the support plate 9 slides inside the adjacent slot 12. An assembly groove 13 is formed at the end of the sliding plate 11 located outside the fixing plate 7. A sliding block is slidably connected inside the assembly groove 13. A plurality of pushing springs fixed on the sliding block are fixed on the inner wall of the assembly groove 13. A stop block 14 in contact with the adjacent fixing plate 7 is fixed on the side of the sliding block away from the pushing spring. When the breeder places the experimental rabbit between the two fixing plates 7, the experimental rabbit falling between the two fixing plates 7 at this time will be carried by the support plate 9. At this time, the experimental rabbit can be supported by the support plate 9 to avoid the two fixing plates 7 being too long when the experimental rabbit falls between the two fixing plates 7, resulting in the smaller-sized experimental rabbit being injured, thereby effectively protecting the experimental rabbit. And during the process of the breeder using the measuring device, the support plate 9 can be adaptively adjusted according to the body shape of the experimental rabbit. Press the stop block 14 to drive the stop block 14 to displace. When the stop block 14 enters the inside of the assembly groove 13, pull the two fixing plates 7 to drive the two fixing plates 7 to displace away from each other. When the sliding plate 11 disengages from the inside of the slot 12, the support plate 9 can be pulled. At this time, the position of the support plate 9 can be adjusted. And when the corresponding position of the support plate 9 is adjusted, press the stop block 14 to drive the stop block 14 to displace. When the stop block 14 enters the inside of the assembly groove 13, loosen the two fixing plates 7. At this time, through the reset elasticity of the connecting spring, pull the two sliders 16 to reset and pull the two fixing plates 7 to displace for reset. When the sliding plate 11 is inserted into the corresponding slot 12 inside, at this time, through the elasticity of the pushing spring, push the stop block 14 to displace. When the stop block 14 contacts the adjacent fixing plate 7, the support plate 9 is fixed between the two fixing plates 7.

[0039] The stop block 14 slides inside the notch of the adjacent assembly groove 13. The depth of the assembly groove 13 is greater than the length of the stop block 14. Through the assembly groove 13 with a depth greater than the length of the stop block 14, the stop block 14 can be effectively accommodated.

[0040] A handle is fixed on the outside of the fixing plate 7 at one end of the loading frame 4. Anti-slip patterns are provided on the outer wall of the handle. Through the handle, the user can conveniently pull the fixing plate 7.

[0041] Positioning blocks are fixed at both ends of the mounting plate 5. The frame body 1 is provided with positioning grooves that slidably cooperate with the positioning blocks. The positioning blocks slide inside the adjacent positioning grooves. Through the sliding cooperation of the positioning blocks and the positioning grooves, the stability performance of the mounting plate 5 can be improved.

[0042] One end of the loading frame 4 is provided with a clamping groove, and a clamping block that cooperates with the clamping groove is fixed on the frame body 1. Through the cooperation of the clamping groove and the clamping block, the stability of the deflected loading frame 4 can be improved.

[0043] A mesh bag 22 is fixed at the bottom of the frame body 1. The length of the mesh bag 22 is greater than the length of the mounting plate 5. Through the mesh bag 22, the experimental rabbits can be received to prevent the experimental rabbits from being injured when sliding out of the fixing plate 7.

[0044] The slider 16 is a rectangular block. The width of the slider 16 is greater than the width of the notch of the sliding groove 15. A limiting block 20 that contacts the loading frame 4 is fixed on the carrier plate 3. The limiting block 20 contacts the mounting plate 5. Through the limiting block 20, the stability of the mounting plate 5 can be improved.

[0045] A method for measuring the weight of experimental rabbits includes the following steps:

[0046] S1: Place the experimental rabbit whose weight needs to be measured between the two fixing plates 7, and then measure the weight of the experimental rabbit through the cooperation of the pressure sensor 8 and the display instrument 12;

[0047] S2: After the weight of the experimental rabbit is measured, the loading frame can be rotated to drive the fixing plate and the experimental rabbit to rotate;

[0048] S3: After the experimental rabbit rotates below the mesh bag 22, the mounting plate 5 is turned over to drive the fixing plate and the experimental rabbit to turn over. After the experimental rabbit falls onto the mesh bag 22, the experimental rabbit on the mesh bag 22 can be taken out and placed in the breeding area;

[0049] S4: When the experimental rabbit inside the fixing plate breaks away from the fixing plate, turn over the mounting plate 5 and rotate the loading frame until the fixing plate returns to its original position;

[0050] S5: After the fixing plate returns to its original position, repeat the above steps to continue the weight measurement operation for the remaining experimental rabbits.

[0051] Working principle: When it is necessary to measure the weight of an experimental rabbit, two fixing plates 7 can be pulled at this time, driving the two fixing plates 7 to move away from each other. When the distance between the two fixing plates 7 is large enough, the experimental rabbit can be placed between the two fixing plates 7. At this time, the experimental rabbit falling between the two fixing plates 7 will be carried by the support plate 9. At this time, the experimental rabbit can be supported by the support plate 9 to prevent the experimental rabbit from being injured when falling between the two fixing plates 7. Since the two fixing plates 7 are relatively long, small-sized experimental rabbits may be injured, thus effectively protecting the experimental rabbit. And when the experimental rabbit is placed well, the two fixing plates 7 can be loosened. At this time, through the reset elasticity of the connecting spring, the two sliders 16 can be pulled to reset, and the two fixing plates 7 can be pulled to perform a reset displacement. When the sponge sheet 8 on the fixing plate 7 contacts the experimental rabbit, the experimental rabbit is fixed between the two fixing plates 7 at this time. At this time, the experimental rabbit will press the mounting plate 5, the loading frame 4 and the carrier plate 3. At this time, the stressed carrier plate 3 will press the force receiving block. At this time, the pressure sensor 21 will detect the pressure received by the force receiving block. At this time, the pressure detected by the pressure sensor 21 will be transmitted to the display instrument 6. At this time, the received pressure can be displayed through the display instrument 6. Then, by comparing the data before and after placing the experimental rabbit on the display instrument 6, subtracting the smaller data from the larger data, the weight of the experimental rabbit can be obtained. And when the weight of the experimental rabbit is obtained, through the operation of the hydraulic cylinder 19, the piston end of the hydraulic cylinder 19 can be driven to move, driving the rack plate 18 to move, driving the driving gear 17 to rotate. At this time, the rotating driving gear 17 will drive the adapter column to rotate. Then, the rotating adapter column will drive the loading frame 4 to rotate. Then, the rotating loading frame 4 will drive the mounting plate 5 to rotate, driving the fixing plate 7 to rotate, driving the experimental rabbit between the two fixing plates 7 to rotate. When the experimental rabbit is misaligned with the carrier plate 3, the fixing plate 7 can be pushed to drive the fixing plate 7 to flip. When the opening of the enclosure formed by the two fixing plates 7 faces downward, the experimental rabbit between the two fixing plates 7 will break away from between the two fixing plates 7 at this time. At this time, the experimental rabbit breaks away from the fixing component. Then, the fixing plate 7 can be flipped to drive the fixing plate 7 to flip. When the opening of the enclosure formed by the two fixing plates 7 faces upward, through the operation of the hydraulic cylinder 19, the piston end of the hydraulic cylinder 19 can be driven to move, driving the rack plate 18 to move, driving the driving gear 17 to rotate. At this time, the rotating driving gear 17 will drive the adapter column to rotate. Then, the rotating adapter column will drive the loading frame 4 to rotate. Then, the rotating loading frame 4 will drive the mounting plate 5 to rotate, driving the fixing plate 7 to rotate. When the fixing plate 7 is reset, the weight of the remaining experimental rabbits can be measured at this time. It is convenient to use, avoiding opening and closing the fixing component back and forth. The operation is simple. And when the fixing plate 7 moves, through the sliding cooperation of the sliding groove 10 and the sliding plate 11, the sliding plate 11 will move accordingly. And during the process of the cultivator using the measuring device,The support plate 9 can be adjusted adaptively according to the body shape of the experimental rabbit. Press the stopper 14 to drive the displacement of the stopper 14. When the stopper 14 enters the inside of the assembly groove 13, pull the two fixing plates 7 to drive the two fixing plates 7 to move away from each other. When the sliding plate 11 disengages from the inside of the slot 12, the support plate 9 can be pulled. At this time, the position of the support plate 9 can be adjusted. And when the corresponding position of the support plate 9 is adjusted, press the stopper 14 to drive the displacement of the stopper 14. When the stopper 14 enters the inside of the assembly groove 13, loosen the two fixing plates 7. At this time, through the reset elasticity of the connecting spring, pull the two sliders 16 to reset and pull the two fixing plates 7 to reset and move. When the sliding plate 11 is inserted into the corresponding slot 12 inside, at this time, through the elasticity of the pushing spring, push the stopper 14 to move. When the stopper 14 contacts the adjacent fixing plate 7, the support plate 9 is fixed between the two fixing plates 7.,

[0052] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.,
