Description

Technical Field

[0001] This utility model relates to the field of dissection experimental apparatus, and in particular to a rabbit dissection experimental apparatus. Background Technology

[0002] Rabbits are frequently used as laboratory animals in biomedical research. For effective anatomical studies or surgical procedures, rabbits need to be immobilized in a stable position so researchers can easily perform various operations. Traditional dissection tables may lack fixation structures or use ropes to restrain the rabbit's limbs, but these methods are insufficiently effective and inconvenient to use. For example, when using ropes for fixation, it takes a considerable amount of time to adjust the rope position and then tighten it; furthermore, readjusting the structure to change the fixation position is even more difficult.

[0003] A search revealed Chinese patent application CN202320123455.7, which discloses an integrated rabbit dissection table with a structure for fixing experimental tools. The table surface is covered with a silicone pad, and multiple limiting blocks are placed on the surface. Each limiting block has a mounting groove on its bottom end, and a permanent magnet is installed inside the groove. The limiting blocks are attached to the table surface by the permanent magnet. A limiting groove is provided at the upper end of each limiting block, and a telescopic support rod is fixedly installed at the middle of the lower surface of the dissection table. The dissection table in the above-mentioned literature has the following shortcomings: it cannot easily assist in fixing the rabbit's limbs and needs further improvement. Utility Model Content

[0009] The positioning component includes:

[0010] Connecting frame, two connecting frames are staggered, and the connecting frames slide on the inner wall of the bottom of the slide;

[0011] The positioning gears are fixed to the ends of the connecting frame. The positioning gears are adapted to the positioning teeth of the strip frame. The side wall of the positioning gears is connected to the slide by a positioning spring.

[0012] The end frame is fixed to the end of the connecting frame away from the positioning tooth frame. The end frame and the positioning tooth frame at the same end of the connecting frame are located on both sides of the slide.

[0013] The ring is fixed to the outer wall of the end frame on the side away from the connecting frame;

[0014] The straps pass through the same set of strip openings, and the two ends of the straps are fixed in two end frames.

[0015] As a further embodiment of this utility model: the end frame is a U-shaped structure, and a toothed plate is slidably connected to the inner wall of the end frame.

After the position is adjusted, the positioning frame and positioning teeth are engaged by the force of the positioning spring to achieve fixation. The operation is simple and convenient.

[0030] 2. In this utility model, since the two ends of the strap are fixed inside two end frames, the distance between the two end frames is greater than the distance between the two strip openings of the same pair in a stable state. Therefore, when the two connecting frames move towards each other, the strap is in a relaxed state, so as to make better position adjustment. After the adjustment is completed, during the resetting process of the connecting frames, the ends of the two straps move away from each other, so as to tighten the strap and make it easier to fix the limb. The entire operation is achieved by adjusting the position of the connecting frames, which is simple and convenient.

[0031] 3. By setting up a toothed plate and other structures, this utility model can fix the end of the strap using the toothed plate and the teeth; by pressing the two paddles, the toothed plate can be unlocked from the end of the strap, thereby adjusting the effective length of the strap to adapt to rabbits of different sizes and improving its versatility.

[0032] 4. By setting up structures such as limiting rods and limiting blocks, this utility model can lock the limiting rods into the two positioning buckles when the two positioning gears are engaged with the positioning teeth, and place the two limiting blocks on the outside of the two positioning buckles. This can limit the displacement of the positioning gears, prevent the positioning gears from disengaging from the positioning teeth, improve reliability, and make the engagement and disengagement of the limiting rods and positioning buckles convenient and highly practical.

Detailed Implementation

[0040] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] Example 1

[0043] A rabbit dissection experimental apparatus, such as Figure 1-6 As shown, the dissection table 5 includes a support mechanism at its bottom and multiple paired slots 16 on its surface. A limb restraint structure is also provided at the bottom of the dissection table 5, comprising:

[0044] A strip frame 11 is installed on the bottom outer wall of the dissection table 5, and the side of the strip frame 11 is provided with evenly distributed positioning teeth 12.

[0045] The slide 15 and the strip frame 11 have a sliding groove at the bottom. The slide 15 is slidably connected in the sliding groove, and a positioning component is installed on the slide 15.

[0046] The positioning component includes:

[0047] Connecting frame 20, two connecting frames 20 are staggered, and the connecting frame 20 slides on the bottom inner wall of the slide 15;

[0048] Positioning tooth frame 17, two positioning tooth frames 17 are each fixed to the end of the connecting frame 20, the positioning tooth frame 17 is adapted to the positioning tooth 12 of the strip frame 11, and the side wall of the positioning tooth frame 17 is connected to the slide 15 by a positioning spring 18.

[0049] End frame 27 is fixed to the end of the connecting frame 20 away from the positioning tooth frame 17. The end frame 27 and the positioning tooth frame 17 at the same end of the connecting frame 20 are located on both sides of the slide 15, respectively.

[0050] Ring 14, ring 14 is fixed to the outer wall of the end frame 27 on the side away from the connecting frame 20;

[0051] The strap 4 passes through the same set of strip openings 16, and both ends of the strap 4 are fixed inside the two end frames 27;

[0052] Under stable conditions, the distance between the two end frames 27 should be greater than the distance between the two strip openings 16 of the same pair;

[0053] By setting up the dissection table 5 and the limb restraint structure, the rabbit can be placed on the dissection table 5, and the limb restraint structure can be used to restrain and fix the rabbit's limbs, which facilitates experimental operations.

[0054] Because the positioning tooth frame 17 and the positioning tooth 12 are used for positioning, when adjusting the position, the two connecting frames 20 are squeezed to move towards each other, thereby causing the two positioning tooth frames 17 to open and unlock. The position is adjusted based on the slide of the slide 15 sliding in the slide groove. After the position is adjusted, the positioning tooth frame 17 and the positioning tooth 12 are engaged by the force of the positioning spring 18 to achieve fixation; the operation is simple and convenient.

[0055] Since the two ends of the strap 4 are fixed inside the two end frames 27, in a stable state, the distance between the two end frames 27 is greater than the distance between the two strip openings 16 of the same pair. Therefore, when the two connecting frames 20 move towards each other, the strap 4 is in a relaxed state, so as to make better position adjustment. When the adjustment is completed, during the resetting process of the connecting frame 20, the ends of the two straps 4 move away from each other, so as to tighten the strap 4 and make it easier to fix the limb. The whole operation is achieved by adjusting the position of the connecting frame 20, which is simple and convenient.

[0056] Among them, the strap 4 can also be made of a slightly elastic material.

[0057] To better adjust and adapt to different types of rabbits; such as Figure 6 As shown, the end frame 27 has a U-shaped structure. A toothed plate 22 is slidably connected to the inner wall of the end frame 27. The toothed plate 22 and one side inner wall of the end frame 27 are connected by a second spring 21. The other side inner wall of the end frame 27 is provided with teeth that are adapted to the toothed plate 22. The end of the strap 4 is fixed based on the teeth and the toothed plate 22.

[0058] Both the bottom of the end frame 27 and the bottom of the toothed plate 22 are provided with paddles 23;

[0059] By setting up structures such as the toothed plate 22, the end of the strap 4 can be fixed by the toothed plate 22 and the teeth; by pressing the two paddles 23, the toothed plate 22 can be unlocked from the end of the strap 4, thereby adjusting the effective length of the strap 4 to accommodate rabbits of different sizes and improving its versatility.

[0060] To avoid structural loosening, such as Figure 6 As shown, the top of the two connecting frames 20 is fixed with positioning buckles 26, the bottom of the slide 15 is installed with a telescopic slide rod 25, the bottom end of the telescopic slide rod 25 is fixed with a limit rod 19, the limit rod 19 is provided with a limit block 24, the positioning buckle 26 is located above the limit rod 19, and the width of the limit block 24 is greater than the width of the positioning buckle 26.

[0061] When the two positioning gears 17 mesh with the positioning teeth 12, the distance between the two limiting blocks 24 is slightly greater than the distance between the two positioning buckles 26.

[0062] By setting up structures such as limiting rod 19 and limiting block 24, when the two positioning gears 17 are engaged with the positioning teeth 12, the limiting rod 19 can be inserted into the two positioning buckles 26, and the two limiting blocks 24 can be located outside the two positioning buckles 26. This can limit the displacement of the positioning gears 17, prevent the positioning gears 17 from disengaging from the positioning teeth 12, improve reliability, and the engagement and disengagement of the limiting rod 19 and the positioning buckles 26 are convenient and highly practical.

[0063] To improve practicality; such as Figure 3 As shown, the support mechanism includes:

[0064] Annular mounting base 1, on which a rotating base 2 is rotatably mounted;

[0065] A rotation limiting part is mounted on an annular mounting base 1, and the rotation limiting part is used to limit the rotation of the rotating base 2;

[0066] Support cylinder 7 is fixed on rotating seat 2, and support rod 6 is installed on support cylinder 7. The top of support rod 6 is fixed on dissecting table 5.

[0067] To facilitate limiting the rotation of the rotating seat 2; such as Figure 1 As shown, the limiting part includes:

[0068] Guide frame 9 is installed on one side of the outer wall of the annular mounting base 1;

[0069] Card holder 8 is slidably connected to the outer wall of guide frame 9. The top of rotating seat 2 is provided with evenly distributed card slots 10. One end of card holder 8 is detachably locked in card slot 10.

[0070] By setting up structures such as the annular mounting base 1 and the limiting part, the rotating seat 2 can be rotated within the annular mounting base 1 as needed, the position of the dissection table 5 can be adjusted, and the rotating seat 2 can be limited and fixed based on the insertion of the end of the card holder 8 into the card slot 10. The column structure of the guide frame 9 adopts a prismatic shape.

[0071] To improve the smoothness of rotation; such as Figure 3 As shown, the annular mounting base 1 and the rotating base 2 are provided with matching annular grooves on their adjacent sides, and a plurality of movable balls 13 are installed in the annular grooves.

[0072] To facilitate adjustment of the structural height; such as Figure 1 As shown, the support rod 6 is slidably connected to the inner wall of the top of the support cylinder 7, and a fixing knob 3 for fixing the support rod 6 is threadedly connected to the inner wall of one side of the support cylinder 7.

[0073] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
