[0036] The following is combined with Figure 1 to Figure 4 The utility model is further described in detail, but it is not intended to limit the utility model.
[0037] like Figure 1 and Figure 2As shown in the figure, a fixing device for animal dissection experiments comprises a base 11, a first fixing structure 28 and a second fixing structure 29 which are arranged on the base 11 and have the same structure, wherein the first fixing structure 28 and the second fixing structure 29 are arranged on the base 11 to form an animal placement area 12;
[0038] The first fixed structure 28 and the second fixed structure 29 both include a first sliding groove 21, a second sliding groove 22, a limiting groove 23, a sliding member 24 and a fixing belt 25. The first sliding groove 21 and the second sliding groove 22 are connected to each other and are arranged on the base 11. The limiting groove 23 is arranged closely and parallel to the side of the first sliding groove 21. The sliding member 24 is slidably inserted in the first sliding groove 21 and slidingly cooperates with the inner wall of the first sliding groove 21. The sliding member 24 has a through groove 241. The fixing belt 25 passes through the through groove 241 and is clearance-matched with the sliding member 24, and both ends of the fixing belt 25 are fixedly connected to the base 11.
[0039] Specifically, when performing dissection operations, the first fixing structure 28 and the second fixing structure 29 are used to fix the limbs and head of the animal respectively to prevent the animal from moving around during fixation and affecting the accuracy of the dissection. In this embodiment, the limbs of the animal are first placed between the fixing belt 25 and the base 11, and then the sliding member 24 is moved toward the direction of the animal's limbs. The fixing belt 25 is tightened by the sliding member 24 to fix the animal's limbs. At the same time, since the sliding member 24 can move in the first sliding groove 21, the device can fix animals of different sizes, greatly improving the versatility of the device.
[0040] Specifically, the first fixing structure 28 is arranged corresponding to the animal's head and is used to fix the animal's head, the second fixing structure 29 is arranged corresponding to the animal's limbs and is used to fix the animal's limbs, the first fixing structure 28 is arranged on the upper side of the base 11, and the second fixing structure 29 is symmetrically arranged on both sides of the first fixing structure 28.
[0041] In this embodiment, the second fixing structure 29 is symmetrically arranged on both sides of the placement area 12, and the first fixing structure 28 is opposite to the placement area 12. Before performing the dissection work, the animal's body is placed in the placement area 12, and then the animal's limbs and head are fixed by the first fixing structure 28 and the second fixing structure 29 respectively. After the operation is completed, the structural operation can begin.
[0042] like Figure 3 and Figure 4As shown, in some embodiments, there is a fixed space between the fixing belt 25 and the base 11, and the fixed space is divided into a first fixed space 26 and a second fixed space 27 by a sliding member 24. When the sliding member 24 moves from the middle of the fixing belt 25 to the right side of the fixing belt 25, the fixing range of the first fixed space 26 is greater than the fixing range of the second fixed space 27. When the sliding member 24 moves from the middle of the fixing belt 25 to the left side of the fixing belt 25, the fixing range of the second fixed space 27 is greater than the fixing range of the first fixed space 26.
[0043] Specifically, in this embodiment, when the sliding member 24 is in the initial position, that is, when the sliding member 24 is close to the leftmost side of the fixing belt 25, the fixing range of the second fixing space 27 is the largest, and the animal's limbs can be easily placed in the second fixing space 27. After the animal's limbs are placed in the second fixing space 27, the sliding member 24 moves to the rightmost side of the fixing belt 25, and the fixing belt 25 moves in the through groove 241, and the fixing range of the second fixing space 27 is contracted through the through groove 241 until the second fixing space 27 completely fixes the animal's limbs.
[0044] like Figure 4 As shown, in some embodiments, a convex portion 231 is provided in the limiting groove 23, and the convex portion 231 is in a step shape, a cone shape or an arc shape.
[0045] Specifically, in the present embodiment, the protrusion 231 in the limiting groove 23 is in the shape of a step. The advantage of the step shape is that it only has a one-way sliding effect. After the first fixing structure 28 and the second fixing structure 29 fix the animal, the step-shaped protrusion 231 prevents the sliding member 24 from moving in the opposite direction, thereby ensuring the stability of the fixation.
[0046] like Figure 4 As shown, in some embodiments, the sliding member 24 is provided with a through slot 241 , and the through slot 241 penetrates from one side of the sliding member 24 to the other side of the sliding member 24 , and the fixing belt 25 passes through the through slot 241 .
[0047] Specifically, the fixing belt 25 is arranged in the through groove 241, and the fixing belt 25 passes through the sliding member 24 through the through groove 241. When the sliding member 24 is moved, the fixing belt 25 slides in the through groove 241. In this embodiment, when the sliding member 24 is moved, the fixing belt 25 is contracted through the through groove 241. Before performing the dissection work, the sliding member 24 moves toward the second fixing space 27, so that the fixing range of the second fixing space 27 is contracted and becomes smaller, thereby fixing the animal.
[0048] like Figure 3 and Figure 4As shown, in some embodiments, the sliding member 24 includes a first part 242 and a second part 243, and the second part 243 passes through the first sliding groove 21 and is placed in the second sliding groove 22, the second part 243 includes a fixed part 2412 and a sliding part 2411, the sliding part 2411 is placed in the first sliding groove 21, the fixed part 2412 is placed in the second sliding groove 22, the width of the fixed part 2412 is greater than the width of the first sliding groove 21, the width of the first part 242 is greater than the width of the sliding part 2411, and an accommodating cavity 244 is arranged in the first part 242.
[0049] Specifically, the first part 242 and the second part 243 are integrally arranged, the width of the sliding part 2411 is smaller than the width of the first sliding groove 21, and the first sliding groove 21 guides the sliding part 2411 to prevent it from deviating. When the sliding part 2411 moves, it drives the fixed part 2412 to move in the second sliding groove 22, and the width of the fixed part 2412 is greater than the width of the first sliding groove 21. The entire sliding member 24 is firmly placed in the first sliding groove 21 through the fixed part 2412 to prevent the sliding member 24 from falling out of the first sliding groove 21, and the width of the second part 243 is greater than the width of the first sliding groove 21, which can prevent the sliding member 24 from falling off in the first sliding groove 21, and the second part 243 can also play a limiting role.
[0050] like Figure 4 As shown, in some embodiments, the first part 242 is provided with a pin 245, the pin 245 passes through the accommodating cavity 244 and one end of the pin 245 extends out of the first part 242, the other end of the pin 245 extends from the bottom of the accommodating cavity 244 and is placed in the through groove 241, and the part of the pin 245 extending from the top of the sliding member 24 is provided with a handle 246.
[0051] Specifically, in the present embodiment, the latch 245 cooperates with the limiting groove 23 to fix the sliding member 24. The latch 245 extends from the bottom of the accommodating cavity 244 and is placed in the limiting groove 23, so that the sliding member 24 can only move toward the second fixing space 27. After the fixation is completed, the sliding member 24 is fixed by the latch 245 cooperating with the limiting groove 23 to prevent the rebound force during fixation from causing the sliding member 24 to move toward the left side of the fixing belt 25, resulting in unstable fixation. The portion of the latch 245 extending from the top of the sliding member 24 is provided with a lifting handle 246, and the entire latch 245 can be lifted upward by the lifting handle 246, and then the sliding member 24 can move toward the left side of the fixing belt 25.
[0052] The sliding member 24 is moved toward the right side of the fixing belt 25 to shrink the second fixing space 27 so as to fix the animal. When the user needs to take out the animal after completing the dissection, he only needs to lift the latch 245 through the lifting handle 246 and then move the sliding member 24 toward the left side of the fixing belt 25. The fixing range of the second fixing space 27 becomes larger, and the animal can be taken out of the second fixing space 27.
[0053] The convex portion 231 has a stop surface 2311 and a sliding surface 2312. The stop surface 2311 is perpendicular to the horizontal plane, and the sliding surface 2312 is inclined to the horizontal plane. When performing a fixing operation, the latch 245 is guided by the sliding surface 2312 so that the sliding member 24 can move toward the animal's limbs. At the same time, when the sliding member 24 stops moving, the stop surface 2311 abuts against the latch 245, limiting the sliding member 24 and preventing the sliding member 24 from moving in the opposite direction.
[0054] like Figure 4 As shown, in some embodiments, a middle rod 247 is provided in the accommodating cavity 244, and the middle rod 247 vertically passes through the pin 245. A reset member 248 is also provided in the accommodating cavity 244, and the reset member 248 is sleeved on the pin 245. The reset member 248 is located above the middle rod 247, and the two ends of the reset member 248 respectively abut the middle rod 247 and the sliding member 24.
[0055] Specifically, in the present embodiment, the role of the middle rod 247 is to prevent the latch 245 from falling off. When the latch 245 is lifted by the lifting handle 246, the entire latch 245 may fall off from the sliding member 24. The middle rod 247 provided in the latch 245 can also prevent the entire latch 245 from being lifted up. At the same time, the reset member 248 abuts against the middle rod 247, and the reset member 248 applies elastic force to the latch 245 through the middle rod 247 to reset it.
[0056] In this embodiment, the bottom of the latch 245 is always in contact with the protrusion 231 through the reset member 248 to prevent the sliding member 24 from moving in the reverse direction, thereby improving the stability of the device for fixing animals.
[0057] In specific work, when the animal needs to be fixed, since the staff holds the animal to be dissected in one hand, only one hand can operate. In this embodiment, when fixing the animal, only one hand is needed to move the sliding member 24, which greatly improves the convenience of operation.
[0058] After the dissection work is completed, one only needs to pinch the handle 246 and lift it up, and then move the sliding member 24 in the opposite direction with the palm of the hand to release the fixation of the animal. It is easy to use. When the handle 246 is released, the pin 245 falls down and contacts the protrusion 231 due to the elastic force of the reset member 248, thereby limiting the sliding member 24.
[0059] like Figure 3 and Figure 4 As shown, in some embodiments, at least two latches 245 are provided, and the two latches 245 correspond to the limiting grooves 23 on both sides of the first sliding groove 21 respectively, and the reset member 248 abuts against the middle rod 247, so that one end of the latch 245 placed in the through groove 241 is always in contact with the limiting groove 23.
[0060] Specifically, in the present embodiment, two latches 245 are provided, and the two latches 245 correspond to the limiting grooves 23 respectively, and the latch 245 abuts against the middle rod 247 through the reset member 248 so that the bottom of the latch 245 contacts the protrusion 231 in the limiting groove 23, and the sliding member 24 is fixed by the latch 245 and the protrusion 231 to prevent the sliding member 24 from retreating and causing loose fixation. In the present embodiment, two latches 245 are provided to ensure the consistency of the fixation of the sliding member 24 and prevent the fixation from being unstable due to deviation.
[0061] In some embodiments, the reset member 248 is a spring or a spring.
[0062] Specifically, in the present embodiment, the reset member 248 is a spring. Compared with the spring sheet, the spring has a space in the middle for the latch 245 to pass through. The spring is sleeved on the latch 245, and the spring can better provide elastic support for the latch 245.
[0063] In some embodiments, the fixing strap 25 is a flexible member.
[0064] Specifically, in this embodiment, the fixing belt 25 is made of flexible material. When fixing an animal, using the fixing belt 25 of flexible material can reduce the discomfort of the animal after being fixed, and reduce the struggle of the animal due to the discomfort.
[0065] The specific working process of this embodiment is as follows: first, the sliding member 24 is moved to the left side of the fixing belt 25. At this time, the fixing range of the first fixing space 26 is the smallest, and the fixing range of the second fixing space 27 is the largest, so that the animal's limbs or head can be easily placed in the second fixing space 27. After the limbs of the animal to be fixed are placed in the second fixing space 27, the sliding member 24 is pushed to move in the direction of the animal's limbs or head. The sliding member 24 moves to the place closest to the animal's limbs or head. Since the latch 245 is in contact with the convex portion 231, the sliding member 24 cannot move in the opposite direction, which prevents the sliding member 24 from rebounding due to tension, thereby ensuring the stability of the fixation. After the dissection work is completed, when the animal needs to be taken out, the lifting handle 246 is grasped and lifted upward to disengage the latch 245 from the contact with the convex portion 231, and then the sliding member 24 is pushed to move in the opposite direction of the animal's limbs (that is, the left side of the fixing belt 25) to expand the fixing range of the second fixing space 27, and finally the animal's limbs can be taken out. Through this device, the staff can operate even with one hand, which reduces the difficulty of operation.
[0066] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
[0067] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
