Abstract
Description
Technical Field
[0001] This utility model relates to the field of zebrafish rapid tail-cutting assistance technology, and more specifically, it relates to a zebrafish rapid tail-cutting assistance device. Background Technology
[0002] In existing technologies, auxiliary devices for rapid tail clipping of zebrafish face several key technical challenges. One of the most significant challenges is the non-standardized nature of zebrafish shape and size. Zebrafish exhibit significant individual differences in body shape, including variations in width, thickness, and other aspects. This makes achieving precise and stable clamping during tail clipping a complex issue. Because there is no standardized form for zebrafish, existing clamping devices often cannot be flexibly adjusted to suit the specific conditions of different individual zebrafish, thus making it difficult to achieve optimal fixation.
[0003] Furthermore, while some existing devices utilize specialized components to assist in gripping zebrafish, their structures are relatively simple and lack sufficient stability. When zebrafish are disturbed or begin to struggle, the components in these gripping devices often fail to maintain adequate clamping force, causing the gripping structure to loosen or shift. Consequently, the gripping effect significantly decreases as the zebrafish loses its hold, and may even cause the zebrafish to detach from the gripping device, making tail clipping impossible. This not only affects operational efficiency but may also cause additional harm to the zebrafish, thus impacting experimental results or practical application effectiveness. Utility Model Content

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a zebrafish rapid tail-cutting auxiliary device, which has the following beneficial effects:
[0017] 1. The clamping device and reinforcement mechanism each have significant advantages in this zebrafish quick tail-cutting auxiliary device. First, the clamping device, through the cooperation of the limiting frame, movable rod, movable plate, fixed plate, and compression spring, can accurately and reliably fix the zebrafish. The sliding setting of the limiting frame and the through-hole design of the movable rod make the entire clamping process more flexible and adaptable to zebrafish of different sizes. The action of the compression spring between the fixed plate and the limiting frame ensures that the rubber disc connected to one side of each movable rod can contact the outer surface of the zebrafish's body, thereby realizing the clamping of zebrafish of different shapes and sizes, effectively improving the flexibility of the equipment and achieving the best fixation effect.
[0018] 2. The reinforcement mechanism, through the cooperation of components such as the motor, reducer, lead screw, and transmission wheel, ensures the stability of the clamping device and the transmission of force. The cooperation of the motor and reducer enables the precise rotation of the lead screw, thereby driving the first and second fixed frames to move smoothly on the clamping sleeve. The symmetrical thread design on the lead screw allows each set of the first and second fixed frames to achieve bidirectional synchronous movement, ensuring that the clamping sleeve can stably fix the movable rod. The cooperation of the slide rail and slide groove makes the movement of the first and second fixed frames more stable and smooth. Through the cooperation of the above components, the movable rod is effectively fixed, preventing the movable rod from moving after clamping, thereby avoiding deviations or instability during the clamping process.

[0028] Please see Figures 1-5 A zebrafish rapid tail-cutting auxiliary device includes a fixed base 1, in which a clamping device is installed. The clamping device includes a limiting frame 2, movable rods 3, movable plates 4, fixed plates 5, and a compression spring 6. The limiting frame 2 is slidably disposed inside the fixed base 1. Multiple movable rods 3 slide through the movable plates 4 and the limiting frame 2. The movable plates 4 are detachably mounted on some parts of the limiting frame 2. The fixed plates 5 are fixedly mounted on the movable rods 3. The compression spring 6 is movably sleeved on the outside of the movable rods 3. The two ends of the compression spring 6 are respectively attached to the inner walls of the fixed plates 5 and the limiting frame 2. The connection and the fixed base 1 are provided with a reinforcement mechanism, which includes a motor 7, a first fixed frame 8, a second fixed frame 9, a clamping sleeve 10, a lead screw 11 and a partition groove 12. The first fixed frame 8 and the second fixed frame 9 are respectively movably installed on one side of the movable plate 4, and the first fixed frame 8 and the second fixed frame 9 are respectively movably connected to the lead screw 11 by threads. The clamping sleeve 10 is fixedly installed on the first fixed frame 8 and the second fixed frame 9. The lead screw 11 is rotatably installed on one side of the movable plate 4, and the partition groove 12 is opened on the lead screw 11.
[0029] The first fixed frame 8 and the second fixed frame 9 are symmetrically arranged on both sides of the corresponding movable rod 3. Between the two partition grooves 12 is a lead screw 11, and each lead screw 11 is symmetrically provided with opposite threads.
[0030] A reducer 13 is detachably installed on one side of the movable plate 4. The input end of the reducer 13 is connected to the output end of the motor 7, and the output end of the reducer 13 is connected to one end of the lead screw 11.
[0031] A rubber disc 14 is fixedly connected to one end of the movable rod 3.
[0032] The fixed base 1 is detachably equipped with multiple cylinders 15, and the output end of the cylinder 15 is connected to a piston rod 16. The other end of the piston rod 16 is detachably connected to the limit frame 2.
[0033] In this embodiment, when the device is needed, the motor 7 is first turned on, so that the output end of the motor 7 drives the lead screw 11 connected to the output end of the reducer 13 to rotate after being decelerated by the reducer 13. Then the lead screw 11 drives the transmission wheel 17 connected to the other end to rotate. Then the transmission wheel 17 here drives the transmission wheel 17 connected to one end of the other lead screw 11 to rotate through the transmission belt 18 sleeved on the outside, so that the two lead screws 11 rotate synchronously in the same direction. Since the first fixed frame 8 and the second fixed frame 9 are movably connected to the lead screw 11 by threads, and the lead screw 11 between the two partition grooves 12 is symmetrically provided with opposite threads, the two first fixed frames 8 symmetrically arranged on both sides of the movable rod 3 form a group, and the two second fixed frames 9 symmetrically arranged on both sides of the movable rod 3 form a group. Then the two first fixed frames 8 and the two second fixed frames 9 of each group will move along the slide rail 19 and the slide groove 20 to both sides of the movable rod 3, so that the first fixed frames 8 and the second fixed frames 9 drive the clamping sleeve 10 to move to both sides, and then the clamping sleeve 10 no longer... The outer wall of the movable rod 3 is clamped by the anti-slip strip 21. Then, the zebrafish is taken out of the water and placed between the two movable plates 4. Then, the cylinders 15 on both sides are opened simultaneously. The cylinders 15 push the limit frame 2 to move through the piston rod 16 connected to the output end. Then, the limit frame 2 drives the movable plate 4 to move inward. Then, the movable plate 4 drives the multiple movable rods 3 and the rubber plate 14 to gradually approach the sides of the zebrafish. Then, the rubber plate 14 will gradually come into contact with the outside of the zebrafish. Then, the rubber plate 14 and the movable rods 3 in contact with the zebrafish body will not... Then, the limiting frame 2 and the movable plate 4 continue to move. The limiting frame 2 and the fixed plate 5 on the outside of the movable rod 3 will cooperate to compress the compression spring 6, so that the movable rod 3 will slide relative to the limiting frame 2 and the movable plate 4. Then the limiting frame 2 and the movable plate 4 will continue to drive the other movable rods 3 and the rubber disc 14 to continue to move closer to the zebrafish. When the zebrafish is fixed by the rubber disc 14 on one side of the movable rod 3, all the compression springs 6 will be compressed to different degrees. Then all the cylinders 15 will be closed simultaneously.
[0034] Please see Figures 1-5 As a further implementation of the overall equipment: a transmission wheel 17 is detachably connected to one end of the lead screw 11, and a transmission belt 18 is movably sleeved on the outside of the transmission wheel 17.
[0035] A slide rail 19 is fixedly provided on one side of the movable plate 4, and a slide groove 20 is provided on one side of both the first fixed frame 8 and the second fixed frame 9, and the slide rail 19 and the slide groove 20 are compatible.
[0036] Multiple anti-slip strips 21 are fixedly provided in the clamping sleeve 10.
[0037] More specifically, after the zebrafish is fixed in place by the rubber disc 14 on one side of the movable rod 3, the motor 7 on one side of the movable plate 4 is driven in the reverse direction, causing the motor 7 to rotate in the opposite direction. Then, after being slowed down by the reducer 13, the output end of the motor 7 drives the lead screw 11 connected to the output end of the reducer 13 to rotate in the opposite direction. Then, the lead screw 11 drives another lead screw 11 to rotate in the opposite direction through the cooperation of the transmission belt 18 and the transmission wheel 17. This causes the first fixing frame 8 and the second fixing frame 9 to drive the clamping sleeve 10 to slide along the slide rail 19 and the slide groove 20, and causes the clamping sleeve 10 to gradually move closer to the movable rod 3. Then, the clamping sleeves 10 on both sides will gradually contact the outer wall of the movable rod 3 and press the anti-slip strip 21 on the inner side. This allows the clamping sleeve 10 to stably fix the movable rod 3 through the multiple anti-slip sleeves on the inner side. Then, the motor 7 can be turned off, thereby achieving effective fixation of the movable rod 3, thus ensuring the stable fixation of the zebrafish and ensuring that the tail-cutting work can be carried out stably.
[0038] In summary, when the entire device is in use or operation: First, the motor 7 is turned on, causing the output end of the motor 7 to rotate after being reduced by the reducer 13. Then, the lead screw 11 connected to the output end of the reducer 13 rotates. The lead screw 11 then drives the transmission wheel 17 connected to the other end to rotate. This transmission wheel 17, through the transmission belt 18 sleeved on the outside, drives the transmission wheel 17 connected to one end of the other lead screw 11 to rotate, thus causing the two lead screws 11 to rotate synchronously and in the same direction. Since the first fixed frame 8 and the second fixed frame 9 are movably connected to the lead screw 11 via threads, and the lead screw 11 between the two partition grooves 12 has symmetrically arranged opposite threads, the two first fixed frames 8 symmetrically arranged on both sides of the movable rod 3 form one group, and the two second fixed frames 9 symmetrically arranged on both sides of the movable rod 3 form another group. Then, the two first fixed frames 8 and the two second fixed frames 9 in each group will move along the slide rail 19 and slide groove 20 to both sides of the movable rod 3, causing the first fixed frames 8 and the second fixed frames 9 to drive the clamping sleeve 10 to move to both sides, thus clamping... The sleeve 10 no longer clamps the outer wall of the movable rod 3 with the anti-slip strip 21. Then, the zebrafish is taken out of the water and placed between the two movable plates 4. Then, the cylinders 15 set on both sides are opened simultaneously. The cylinders 15 push the limit frame 2 to move through the piston rod 16 connected to the output end. Then, the limit frame 2 drives the movable plate 4 to move inward. Then, the movable plate 4 drives multiple movable rods 3 and rubber discs 14 to gradually approach the sides of the zebrafish. Then, the rubber discs 14 will gradually come into contact with the outer side of the zebrafish. Then, the rubber discs 14 and the movable rods 3 that are in contact with the zebrafish's body will come into contact with the outer side of the zebrafish. Rod 3 stops moving, while limit frame 2 and movable plate 4 continue to move. Then, limit frame 2 and fixed plate 5 on the outside of movable rod 3 will cooperate to compress spring 6, causing movable rod 3 to slide relative to limit frame 2 and movable plate 4. Then, limit frame 2 and movable plate 4 will continue to drive other movable rods 3 and rubber disc 14 to move closer to the zebrafish. When the zebrafish is fixed by rubber disc 14 on one side of movable rod 3, all compression springs 6 will be compressed to different degrees, and then all cylinders 15 will be closed simultaneously.
[0039] After the zebrafish is fixed in place by the rubber disc 14 on one side of the movable rod 3, the motor 7 on one side of the movable plate 4 is driven in the reverse direction, causing the motor 7 to rotate in the opposite direction. Then, after being slowed down by the reducer 13, the output end of the motor 7 drives the lead screw 11 connected to the output end of the reducer 13 to rotate in the opposite direction. Then, the lead screw 11 drives another lead screw 11 to rotate in the opposite direction through the cooperation of the transmission belt 18 and the transmission wheel 17. This causes the first fixing frame 8 and the second fixing frame 9 to drive the clamping sleeve 10 to slide along the slide rail 19 and the slide groove 20, and causes the clamping sleeve 10 to gradually move closer to the movable rod 3. Then, the clamping sleeves 10 on both sides will gradually contact the outer wall of the movable rod 3 and press the anti-slip strip 21 on the inner side. This allows the clamping sleeve 10 to stably fix the movable rod 3 through the multiple anti-slip sleeves on the inner side. Then, the motor 7 can be turned off, thus achieving effective fixation of the movable rod 3, thereby ensuring the stable fixation of the zebrafish and ensuring that the tail-cutting work can be carried out stably.
