Technical Field

[0001] The utility model relates to the technical field of simulated weightlessness experiment devices, in particular to a feeding trough device applied to a tail-suspended rat device for simulating weightlessness. Background Technique

[0002] The tail-suspended rat model is a classic animal model for simulating weightlessness on the ground. In this model, the hind limb load of the rat is removed by tail suspension, while the forelimbs still bear the load, achieving the simulation of hind limb weightlessness-induced bone loss effect or the influence of weightlessness on certain physiological systems of animals without affecting the endocrine system of the rats.

[0003] The tail-suspended rat cage for simulating weightlessness is an important experimental device in the tail-suspended rat model. The existing tail-suspended rat cage for simulating weightlessness 01 is as Figure 1 shown. A rat feed trough 02 is fixedly installed on one side of it. The rat feed trough 02 has an open top structure. Although it is easy to put rat feed into it, when the rat modeling is completed and it is necessary to detect the food intake of the rats or when the rats are fasted for modeling, the staff needs to use tweezers to pick out the rat feed one by one, which is time-consuming and laborious.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] The purpose of the present utility model is to provide a feeder trough device applied to the tail-suspended rat device for simulated weightlessness to solve the problems existing in the prior art. The rat feed in the feeder trough device is convenient to take out, reducing the manual workload during the fasting period and the end period of rat modeling.

[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0027] As Figure 2 shown, this embodiment provides a feeder trough device applied to the tail-suspended rat device for simulated weightlessness, including a feeder trough body 1. The feeder trough body 1 is used to hold rat feed. Specifically, the feeder trough body 1 in this embodiment is a square trough with a length of 10 cm, a width of 6 cm, and a height of 5 cm. The top and the front side of the feeder trough body 1 are both open, and a partition board 2 is movably arranged on the front side of the feeder trough body 1. The partition board 2 is used to open or close the feeder trough body 1. Specifically, the partition board 2 in this embodiment is slidably inserted vertically into the front opening of the feeder trough body 1. A chute 3 is arranged at the bottom of the feeder trough body 1, and a pull rod 4 is slidably embedded in the chute 3. A discharge plate 5 is connected to the pull rod 4. When it is necessary to take out the rat feed in the feeder trough body 1, by pulling up the partition board 2 to open the feeder trough body 1 and pulling the pull rod 4 outwards, the discharge plate 5 is driven to dial out the rat feed in the feeder trough body 1, which is convenient and fast, reducing the manual workload during the fasting period and the end period of rat modeling.

[0028] It should be noted that the front side of the feeding trough body 1 refers to the side of the feeding trough body 1 that is away from the simulated weightlessness tail-suspended rat device when the feeding trough body 1 is installed on the simulated weightlessness tail-suspended rat device, that is, the side of the feeding trough body 1 facing the staff.

[0029] In this embodiment, both the sliding groove 3 and the pull rod 4 extend in the front-to-rear direction; the discharge plate 5 is vertically arranged in the feeding trough body 1 and is fixedly connected to the rear end of the pull rod 4, and the left side, right side, and bottom side of the discharge plate 5 are respectively in contact with the left side wall, right side wall, and bottom wall of the feeding trough body 1 to prevent rat feed from falling into the feeding trough body 1 during the process of pulling the discharge plate 5 outwards.

[0030] Furthermore, as Figure 3 shown, a limiting groove 301 is arranged at the bottom of the sliding groove 3 along its extending direction, and a limiting block is arranged at the bottom of the pull rod 4 along its extending direction. The limiting block is slidably embedded in the limiting groove 301 to limit the displacement of the pull rod 4 in the vertical direction; the cross-section of the limiting groove 301 in this embodiment is trapezoidal. Those skilled in the art can also choose shapes such as circular and rhombic, as long as it can play a role in preventing the pull rod 4 from easily detaching from the sliding groove 3.

[0031] In this embodiment, the front end of the pull rod 4 extends outside the sliding groove 3 and is provided with a handle 6 to facilitate the staff to pull the pull rod 4.

[0032] In this embodiment, the feeding trough device further includes a support 7 and a weighing instrument 8. The support 7 can be fixed to the simulated weightlessness tail-suspended rat device through a fastening screw 9. The weighing instrument 8 is arranged on the support 7, and the feeding trough body 1 is arranged on the weighing instrument 8. The weighing instrument 8 is used to weigh the rat feed in the feeding trough body 1.

[0033] In this embodiment, the weighing instrument 8 is an electronic scale, and the maximum range of the electronic scale is 80 g; when modeling by irregular diet fasting and detecting the food intake, the mass of the remaining rat feed in the feeding trough body 1 can be weighed by the electronic scale.

[0034] In this embodiment, the display screen of the electronic scale is located on the left or right side of the feeding trough body 1, which neither affects the taking out of the rat feed in the feeding trough body 1 nor is convenient for reading.

[0035] In summary, the feeding trough device applied to the simulated weightlessness tail-suspended rat device provided in this embodiment has the following advantages:

[0036] First, by setting the pull-out partition 2, the workload of completely taking out the food during the rat fasting period and the end period of rat modeling is reduced.

[0037] Second, by setting up the weighing instrument 8, the step workload during the irregular diet fasting modeling period and when detecting the food intake is reduced.

[0038] In the present utility model, specific examples are used to expound the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
