Description

[Detailed description of the invention] The present invention relates to a water supply device for an animal breeding device, and the purpose of this invention is to facilitate the installation of the water supply device and prevent the escape of the housed animals, especially in an animal breeding device equipped with a large number of cages. It is something.

Conventional animal breeding, especially the breeding of laboratory animals used for drug administration tests, is so-called group breeding, and the effects of test drugs are not investigated individually.

However, in recent years, drug safety standards have become stricter, and it has been pointed out that the results of drug administration tests using group rearing are quite rough, and it is being proposed that breeding should be shifted from group rearing to individual rearing.

When breeding each individual in this way, a breeding cage must be installed for each individual, a large number of breeding cages are required, the structure of the entire breeding device becomes complicated, and monitoring of each individual becomes insufficient.

For example, a water supply device must be installed for each cage housing an individual, but if a number of water supply nozzles corresponding to the number of cages are welded to one water pipe, the length of the water pipe will be increased due to the welding heat. The water supply nozzle is no longer able to enter the cage through the hole provided in the back wall of each cage.

That is, in the case of welding a small number of water supply nozzles, welding can be performed in accordance with the designed position, but in the case of a large number of welding nozzles, the welding position shifts due to welding heat.

On the other hand, when the cage is pulled out from the shelf or partially pulled out toward the front for feeding, the water nozzle hole on the back wall of the cage is opened, and experimental animals such as rats and mice can be fed through this part. It often happens that the water escapes, and it is not appropriate to make the through hole larger to absorb the leakage at the water supply nozzle position.

In this way, in a breeding facility with a large number of individual cages, in order to install a water supply mechanism and prevent experimental animals from escaping,
Sufficient consideration should be given, and the present invention was developed in view of these points.

The following explanation will be given according to the drawings. Reference numeral 1 is a frame body bridging a plurality of shelves 2, 3 is a cage for breeding experimental animals, etc., and the cage 3 is a pair of It is suspended by a rail 4 so that it can be pulled out toward the front.

However, the cage 3 may be slidably installed above the shelf, or the front wall 5 and back wall 6 of the cage 3 may be panels, and the rest may be made of wire mesh 7.

8 is a feeding box provided inside the cage 3.

9 is a water storage tank placed on the frame 1;
The main pipe 10 is connected to a main pipe 10 that hangs down behind the cage 3, and a water supply pipe 11 is installed horizontally on the main pipe 10, which is located behind approximately the center of the back wall 6 of the cage 3. A tapered recess 12 concave toward the inside of the cage 3 is formed approximately at the center of the back wall 6, and a through hole 13 is provided at the bottom of the tapered recess 12.

A screw hole 1 is located at the position of the water supply pipe 11 corresponding to this through hole 13.
4 is provided in the screw hole 14, and a screw thread 1 is provided on the bottom periphery of the screw hole 14.
A water supply nozzle 16 marked with No. 5 is fitted.

In this specification, the water supply nozzle refers to the spring 17.
The nozzle 18, which is pressed outward by the pressure, protrudes from one end,
This is a type of cage in which a water channel is formed and water is discharged by pushing the nozzle 18 by the domestic animal in the cage 3.

When the cage is inserted into the shelf 3, the water supply nozzle 16 is inserted into the through hole 13 formed in the back wall 6 of the cage 3.
It is configured such that its tip faces the inside of the cage 3.

Since the present invention is constructed as described above, the distance between the through holes 13 of the cage 3 to be inserted is measured, and the screw holes 14 are drilled in the water supply pipe 11 in advance according to the determined distance. A water supply pipe 11 having a plurality of screw holes 14 is horizontally installed in the main pipe 10 along the back wall 6 of the cage 3.

Next, the water supply nozzle 16 is screwed into the screw hole 14.

In this state, when the cage 3 is moved and inserted behind the frame 1 along the rail 4, the water supply nozzle 16 enters the tapered recess 12 and the through hole 13 of the cage 3, and its tip is inserted into the cage 3. to be located within.

Thus, when the cock (not shown) of the water storage tank 9 is opened, the water reaches the water supply nozzle 16, and the bred animal can reach the water supply nozzle 16.
By pressing 8, the animal can drink water.

As described above, in the water supply device of the present invention, holes for the water supply nozzle are drilled in advance in each part of the water supply pipe corresponding to the back wall of the cage, and after the water supply pipe is connected to the main pipe. Since the water supply nozzle is fitted, there is less blackout of the water supply nozzle position compared to the case where many water supply nozzles are installed in a row by welding work, and it is suitable as a water supply nozzle for animal breeding equipment with many cages. In addition, a tapered recess is formed on the back wall of the cage, and a through hole is provided at the bottom of the cage, so even if there is a slight deviation in the water supply nozzle spacing, The water supply nozzle can be set into the through hole relatively easily.

Furthermore, when the cage is pulled out to put food into the feeding box, the water supply nozzle moves away from the hole and the hole is not blocked, which has traditionally prevented experimental animals from escaping. However, in the present invention, the bottom of the tapered recess protrudes inward from the cage, so even if the experimental animal tries to escape through this hole, it has no foothold, and it also feels psychologically like an obstacle. This is to prevent domestic animals from escaping.

In particular, as mentioned above, since the accuracy of the water supply nozzle position is improved as much as possible, the diameter of the through hole can also be made as small as possible, so even if the water supply nozzle is pulled out from the through hole, The holes are extremely small, making it even more difficult for domestic animals to escape.
