Description

[Detailed description of the invention] The present invention is an automatic water supply mount, that is, a multi-stage automatic water supply mount in which a plurality of experimental animal rearing cages are placed on each shelf and water is automatically supplied to each cage.
It relates to a mechanism that allows all the cages to be simultaneously held in a position where they are in contact with the water supply nozzle with one touch.

Conventionally, when placing cages for breeding experimental animals on each shelf of an automatic water supply rack, the cages for raising experimental animals were placed on each shelf with proper markings. If there was too much space between the water supply nozzle placed at the end of the cage and the cage, water could not be supplied, which often resulted in the death of the animal. Furthermore, in the past, there was a great risk that the cages would fall from the pedestal due to an earthquake, causing confusion between the cages and the animals escaping.

In view of this, the present invention has been developed by simultaneously moving all the cages placed on each shelf to a position where the rear surface contacts the water supply nozzle arranged at the rear end of the shelf. The cage was designed to be able to hold the cage, and also to prevent the cage from flying out in the event of an earthquake.
Hereinafter, a more detailed explanation will be given based on the illustrated embodiment.

FIG. 1 is a front view of an automatic water supply frame embodying the present invention, FIG. 2 is a side view of the same, and FIG. 3 is a perspective view of a stay.

In the figure, reference numeral 1 denotes a multi-stage automatic water supply frame, and water supply nozzles 3 are arranged at the rear end of each shelf 2 in a number corresponding to the number of cages. Reference numeral 4 denotes a rotating shaft disposed above the front end of each shelf 2, and a required number of press plates 5 are fixed in correspondence with the water supply nozzles 3 in the axial direction. Further, both ends of the rotating shaft 4 are rotatably supported by bearings 6. Reference numeral 7 denotes an arm rod whose base end is connected and fixed to the end of the rotating shaft 4, and whose tip end is pivoted via a pin 8 to a connecting rod 9 which is arranged to be able to reciprocate in the vertical direction of the pedestal. It is connected. Further, one of the arm rods 7 7' is formed longer than the other arm rods. Reference numeral 10 denotes a tension spring stretched between the connecting rod 9 and the shelf 2, which constantly applies an upward biasing force to the connecting rod 9.
Reference numeral 11 denotes a stay consisting of a bracket portion 11a and a main body 11b, in which a base portion of the main body 11b having an axially elongated hole 11c is rotatably connected to the bracket portion 11a. As for the stay 11, the pin of the arm rod 7 to be described later that fits into the elongated hole 11c is in the elongated hole 1.
It is desirable to have one that is automatically locked when it reaches the tip of 1c. Then, the bracket portion 11a of the stay 11 is fixed to the shelf 2, and the pin 12 installed near the tip of the arm rod 7' is slidably fitted into the elongated hole 11c of the stay body 11b. . 13 has one end connected to the arm rod 7' and the other end connected to the frame 1
This is a tension chain that hangs exposed from the front of the machine.

In addition, 14 in the figure indicates a cage.

Next, the mode of operation of the present invention will be explained.

First, the case where the cage 14 is placed on the shelf 2 will be described. When the tension chain 13 is pulled, the arm rod 7' rotates about the rotation shaft 4 as a rotation fulcrum. As the arm rod 7' rotates, the connecting rod 9 moves downward against the force of the tension spring 10, and all the arm rods 7 connected thereto simultaneously move downward (clockwise in the figure). ). Then, the pin 12 installed in the arm rod 7' slides to the tip of the elongated hole 11c of the stay 11 and rotates until it is locked. As the arm rod 7 rotates, the rotating shaft 4 connected and fixed to its base also rotates, and the pressing plate 5 fixed thereto is lifted upward. Therefore, the cage can be placed without any hindrance.
Moreover, it is only necessary to pull the tension chain 13 on which all the cages have been placed, and thereby the pin 12 of the arm rod 7' is removed from the tip of the elongated hole 11c of the stay 11. Therefore, the connecting rod 9 rises again due to the restoring force of the tension spring 10, causing all the arm rods 7 to simultaneously rotate upward. As a result, the rotating shaft 4 also rotates in the same direction as the arm rod 7, so that the pressing plate 5 presses the end of the cage 14 on the front side of the base and pushes it toward the back of the shelf.

Therefore, even if the cages 14 placed on the shelf 2 are shifted in the front-back direction when placed, they are all simultaneously pushed out to the same position toward the back of the shelf 2.

Since the present invention has the above-mentioned structure and operation, even if the cages placed on the shelf are shifted in the front and back direction when placed, they can all be pushed out to the back of the shelf at the same time with a single touch operation. can be retained. Therefore, it is possible to supply water properly, eliminate the death of animals due to inability to supply water as in the past, and speed up the work of placing cages. Moreover, since each cage is pressed and held from the outside by a pressing plate, it is highly effective in preventing the cage from slipping even if the pedestal is shaken by an earthquake or the like. Furthermore, the present invention has many benefits, such as being able to be implemented on any frame currently in use.
