Description

A fixed experimental operating table for rabbits

technical field

The utility model belongs to the technical field of animal experiment devices, in particular to a fixed experimental operation table for rabbits.

Background technique

At present, the experimental operation platform for rabbits, referred to as the rabbit platform, mainly includes the operation platform, and four binding ropes are fixed at the four corners of the operation platform. Use four binding ropes to fasten the four legs of the rabbit, and then start the experimental operation. The disadvantage of this kind of experimental operation table is that the binding rope is too tight to stimulate the rabbit, which will cause the rabbit’s emotions to lose control and affect the operation of the rabbit. Experimental results and experimental process; if the binding rope is too loose, the rabbit is easy to break free, which may cause trauma to the experimenter; in addition, the binding rope is a soft structure, and there is still a large stretching space for the limbs of the rabbit after binding. Struggle of the rabbit provides the possibility, the more the rabbit struggles, the more it loses control of its emotions, resulting in a vicious circle and making it difficult to carry out the experiment.

Contents of the invention

The purpose of the utility model is to propose a fixed experiment console for rabbits aiming at the deficiencies of the prior art.

The utility model solves its technical problem and realizes by taking the following technical solutions:

A rabbit fixed experimental operation platform, including a rectangular experimental platform, at the four corners and the middle of the right end of the experimental platform, a strip-shaped installation hole extending from the center of the platform to the outside is formed, and a lower fixing hole is placed above the installation hole. The snap ring is equipped with fixing bolts on the bottom surface of the lower fixing snap ring. The fixing bolts move in the strip mounting holes to adjust the position of the lower fixing snap ring from the center of the test bench, and the fixing bolts pass through the other side of the test bench. The nut is fixed, and the upper fixed snap ring with the same radius as the lower fixed snap ring is twisted on one end of the lower fixed snap ring through a twisted shaft, and the other end of the lower fixed snap ring is made with a locking bar hole, and the opening and closing of the upper fixed snap ring The end-one system has an elastic locking strip, and triangular blocks are made at regular intervals on the outer surface of the locking strip. When the locking strip is inserted into the locking strip hole, the elasticity of the locking strip will stretch the locking strip to the outside of the locking strip hole. At this time, the triangle The block prevents the lock bar from withdrawing from the lock bar hole.

Moreover, an upper rubber layer is bonded to the inner side of the upper fixing snap ring, and a lower rubber layer is bonded to the inner side of the lower fixing snap ring, and the thickness of the lower rubber layer is greater than or equal to the bolt cap thickness of the fixing bolt.

Moreover, the lower fixed snap ring and the upper fixed snap ring installed on the mounting hole in the middle part of the right end of the experimental table are used to block the neck of the rabbit, and its radius is one-half of the radius of the other four fixed snap rings that block the rabbit's limbs. times.

Advantage and positive effect of the present utility model are:

1. The utility model has a simple structure and a scientific and reasonable design. It adopts a displaceable fixing ring to fix the limbs and neck of the rabbit, and the fixing position is accurate. It is suitable for experiments on rabbits of different sizes.

2. The fixed ring adopted by the utility model has a large fixed contact surface and is firmly fixed. The rabbit is difficult to struggle, and the mood is relatively stable, which brings good prerequisites for the experiment.

3. A rubber layer is added in the fixing ring of the utility model to further reduce the stimulation to the rabbits and reduce the damage to the rabbits.

4. The utility model has reasonable structural concept, simple operation, relatively low cost, and is easy to popularize.

Detailed ways

The implementation of the utility model will be described in further detail below in conjunction with the accompanying drawings. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.

A fixed experiment console for rabbits, as shown in Figure 1 or 2, includes a rectangular experimental platform 1. The innovation of the utility model is that, at the four corners and the middle part of the right end of the experimental platform, there is a The strip-shaped mounting hole 6 extending outside is provided with a lower fixing snap ring 5 above the mounting hole, and a fixing bolt 7 is installed on the bottom surface of the lower fixing snap ring. The fixing bolt moves in the strip-shaped mounting hole, and the lower fixing snap ring is adjusted The distance between the ring and the center of the test bench is fixed by the nut 12 on the other side of the test bench. At one end of the lower fixed snap ring, the upper fixed snap ring 3 with the same radius as the lower fixed snap ring is twisted through the twisted shaft 4. The other end of the lower fixed snap ring is formed with a locking bar hole 8, and an elastic locking bar 2 is integrally formed at the opening and closing end of the upper fixed snap ring. 9. When the lock bar is inserted into the lock bar hole, the elasticity of the lock bar will stretch the lock bar to the outside of the lock bar hole. At this time, the triangular block prevents the lock bar from withdrawing from the lock bar hole, ensuring that the lower fixing snap ring is fixed to the upper part. The snap ring constitutes a complete closed snap ring. When the complete closed snap ring needs to be untied, the locking bar is first pressed against the inner side of the locking bar hole by fingers, and then the triangular block parts are withdrawn one by one, and finally the closed snap ring is untied.

In the specific implementation of the present utility model, an upper rubber layer 10 is bonded to the inner side of the upper fixing snap ring, and a lower rubber layer 11 is bonded to the inner side of the lower fixing snap ring, and the thickness of the lower rubber layer is greater than or equal to the above-mentioned The thickness of the bolt cap of the fixing bolt, the upper rubber layer and the lower rubber layer avoid the hard contact between the fixing snap ring and the rabbit's limbs and neck, and reduce the damage of the fixing snap ring to the rabbit.

In the specific implementation of the present utility model, the lower fixed snap ring and the upper fixed snap ring installed on the mounting hole in the middle part of the right end of the experimental table are used to block the neck of the rabbit, and its radius R is equal to that of the other four blocks. One time of the radius r of the fixed clasp of the rabbit's limbs.
