[0002] A cryostat for small animal culture is a specialized laboratory device that provides a constant low-temperature environment for the cultivation, preservation, and experimental manipulation of small animals, such as insects, mice, and fish. These cryostat chambers typically feature precise temperature control, maintaining a temperature range below room temperature to simulate the natural habitat of small animals or specific experimental conditions. They typically include insulation, temperature control systems, internal lighting, and ventilation systems to ensure animal survival and experimental accuracy.

[0003] The existing low-temperature boxes for small animal culture have the following problems when used:

[0004] 1. Existing low-temperature box designs often place the box lid on top of the box, but are not equipped with the necessary buckles or other fixing structures. This makes it easy for small animals inside the box to push the lid open when they jump, increasing the risk of small animals escaping or foreign matter entering, posing certain safety hazards;

[0005] 2. To supplement the feed of animals in the low-temperature box, it is currently necessary to open the box lid to put the feed into the feed trough. This operation process is not only cumbersome, but also may affect the stability of the temperature in the box due to frequent opening of the lid, which has an adverse effect on the culture environment of the small animals. Utility Model Content

[0006] One purpose of the present invention is to provide a low-temperature box for cultivating small animals. The present invention aims to solve the problems mentioned in the above background, such as the box cover of the existing low-temperature box is not provided with a buckle or other fixing structure, which increases the risk of small animals escaping or external impurities entering, and the need to open the box cover to add feed. Frequent opening or closing of the box cover affects the stability of the temperature in the box.

[0007] According to an embodiment of the present invention, a low-temperature box for cultivating small animals includes a low-temperature box structure to provide a constant-temperature environment for the cultivated small animals. The low-temperature box structure includes an external constant-temperature unit and an incubator. The external constant-temperature unit is interconnected with the internal space of the incubator through an air inlet pipe, an air exhaust pipe, and ventilation holes are opened on both sides of the incubator. A box cover is hinged on the upper surface of the incubator.

[0008] A locking structure installed on the upper surface of the incubator and at both ends of the box cover is used to lock the box cover when it is closed. The locking structure includes a locking hole and a locking clamping rod. The locking holes are installed at both ends of the upper surface of the incubator. Both ends of the upper surface of the box cover are provided with a locking slide groove. The locking clamping rod is slidably connected to the interior of the locking slide groove. A telescopic rod structure is provided between one end of the locking clamping rod and the inner wall of the locking slide groove. The surface of the telescopic rod structure is provided with a first spring structure.

[0009] A feed delivery structure installed at the upper inner end of the incubator achieves the purpose of not opening the box cover when delivering feed. The feed delivery structure includes a feed tank and a baffle. A delivery port is provided on the upper end of the incubator and the surface of the baffle. The baffle is slidably connected to the upper inner end of the incubator. A first fixed block is fixedly connected to the surface of one side of the baffle, and a second fixed block is fixedly connected to the inner upper surface of the incubator. A second spring structure is provided between the first fixed block and the second fixed block. A gear is rotatably connected to the inner upper surface of the incubator, and a gear block is fixedly connected to the other side surface of the baffle.

[0010] Preferably, a locking handle is fixedly connected to the upper surface of the locking rod.

[0011] Preferably, the gear and the gear block are meshed with each other.

[0012] Preferably, a delivery handle is fixedly connected to the upper end of the gear, and the delivery handle is rotatably connected to the upper surface of the incubator.

[0013] Preferably, a sealing cover is threadedly connected to the upper surface of the feed tank.

[0014] Preferably, the rear surface of the incubator is provided with a plurality of inserting plate slots, and the feed delivery structure is provided with a plurality of groups for delivering feed to the small animals in the separated spaces inside the incubator.

[0015] Preferably, a filter is installed at the lower end of the interior of the incubator, and a feed trough is fixedly connected to the surface of the filter.

[0016] Preferably, a collection box is slidably connected to the lower end of the interior of the incubator.

[0017] The beneficial effects of the utility model are:

[0018] The utility model provides a lock structure, and when the box cover needs to be opened during the process of incubating small animals, the lock handle is pulled inward, driving the lock clamping rod to be pulled out from the inside of the lock hole. After the locking force of the lock clamping rod is lost, the box cover can be directly opened from the surface of the incubator. When the box cover is in the closed state, the telescopic rod structure and the first spring structure are in a normal state, ensuring that the lock clamping rod is always in the clamping hole, effectively preventing the box cover from being pushed open by the small animals in the incubator, causing the small animals to escape, etc., ensuring that the box cover can be easily opened when needed, and preventing the small animals from pushing the box cover open and escaping during the incubation process, thereby improving the safety and convenience of the experiment.

[0019] The invention provides a feed delivery structure for feeding small animals, wherein the feed is loaded into the feed tank during the cultivation of small animals, and the baffle blocks the delivery opening at this time. When the small animals inside the incubator need to deliver feed, the delivery handle is rotated, so that the gear drives the baffle to slide through the tooth block. During the sliding of the baffle, the second spring structure is in a stretched state until the delivery opening of the baffle coincides with the delivery opening on the upper surface of the incubator, and the feed inside the feed tank falls downwardly into the feed trough at the bottom end of the incubator for the small animals to eat. After the feed is delivered, the delivery handle is released, and due to the reset elastic force of the second spring structure, the first fixed block is pulled toward the second fixed block, so that the delivery opening on the baffle surface is away from the delivery opening on the upper surface of the incubator. Until the second spring structure is completely reset, the baffle blocks the delivery opening on the upper surface of the incubator again to prevent the feed from continuing to fall, thereby realizing a convenient feed replenishment method and avoiding the influence of frequent opening of the cover on the internal environment of the incubator, thereby improving the efficiency of feeding management and the sealing of the incubator.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0028] refer to Figure 1-5 A low-temperature box for cultivating small animals includes a low-temperature box structure 1, which provides a constant-temperature environment for the cultivated small animals. The low-temperature box structure 1 includes an external constant-temperature unit 13 and an incubator 11. The external constant-temperature unit 13 is connected to the internal space of the incubator 11 through an air inlet pipe 14, an air exhaust pipe 15, and ventilation holes 16 are opened on both sides of the incubator 11. A box cover 12 is hinged on the upper surface of the incubator 11.

[0029] The lock structure 3 installed on the upper surface of the incubator 11 and at both ends of the box cover 12 is used to lock the box cover 12 when it is closed. The lock structure 3 includes a lock hole 31 and a lock clamping rod 36. The lock hole 31 is installed at both ends of the upper surface of the incubator 11. Both ends of the upper surface of the box cover 12 are provided with a lock slide 32. The lock clamping rod 36 is slidably connected to the inside of the lock slide 32. A telescopic rod structure 33 is provided between one end of the lock clamping rod 36 and the inner wall of the lock slide 32. The surface of the telescopic rod structure 33 is provided with a first spring structure 34. Through the provided lock structure 3, when the box cover 12 needs to be opened during the process of incubating small animals, the lock can be opened by When the lock handle 35 is pulled inward, the lock lever 36 is pulled out from the lock hole 31. After the locking force of the lock lever 36 is lost, the box cover 12 can be directly opened from the surface of the incubator 11. When the box cover 12 is in the closed state, the telescopic rod structure 33 and the first spring structure 34 are in a normal state, ensuring that the lock lever 36 is always inside the locking hole, effectively preventing the box cover 12 from being pushed open by small animals inside the incubator 11, causing problems such as the small animals escaping. The box cover 12 can be easily opened when needed, and at the same time, it can prevent small animals from pushing the box cover 12 open and escaping during the incubation process, thereby improving the safety and convenience of the experiment.

[0030] The feed delivery structure 4 installed at the upper end of the incubator 11 can realize the purpose of not opening the box cover 12 when delivering feed. The feed delivery structure 4 includes a feed tank 41 and a baffle 44. A delivery port 45 is provided on the surface of the upper end of the incubator 11 and the baffle 44. The baffle 44 is slidably connected to the upper end of the interior of the incubator 11. A first fixed block 46 is fixedly connected to the surface of one side of the baffle 44. A second fixed block 47 is fixedly connected to the upper surface of the interior of the incubator 11. A second spring structure 48 is provided between the first fixed block 46 and the second fixed block 47. A gear 410 is rotatably connected to the upper surface of the interior of the incubator 11, and a gear block 49 is fixedly connected to the other side surface of the baffle 44. Through the feed delivery structure 4, feed is loaded into the feed tank 41 when culturing small animals. At this time, the baffle 44 blocks the delivery port 45. When the small animals inside the incubator 11 need to be fed, the delivery handle 43 is rotated to make the gear 410 drives the baffle 44 to slide through the tooth block 49. During the sliding process of the baffle 44, the second spring structure 48 is in a stretched state until the feeding port 45 of the baffle 44 coincides with the feeding port 45 on the upper surface of the incubator 11, and the feed inside the feed tank 41 falls downward into the feeding trough at the bottom end of the incubator 11 for the small animals to eat. After the feed is fed, the feeding handle 43 is released. Due to the reset elastic force of the second spring structure 48, the first fixed block 46 is pulled toward the second fixed block 47, so that the feeding port 45 on the surface of the baffle 44 is away from the feeding port 45 on the upper surface of the incubator 11. Until the second spring structure 48 is completely reset, the baffle 44 blocks the feeding port 45 on the upper surface of the incubator 11 again to prevent the feed from continuing to fall, thereby realizing a convenient feed replenishment method and avoiding the impact of frequent opening of the cover on the internal environment of the incubator 11, thereby improving the efficiency of feeding management and the sealing of the incubator 11.

[0031] Example 1: The upper surface of the locking rod 36 is fixedly connected to the locking handle 35, the gear 410 and the gear block 49 are engaged with each other, the upper end of the gear 410 is fixedly connected to the delivery handle 43, the delivery handle 43 is rotatably connected to the upper surface of the incubator 11, the upper surface of the feed tank 41 is threadedly connected to the sealing cover 42, and the rear surface of the incubator 11 is provided with several groups of plug slots 17. The feed delivery structure 4 is provided with several groups for delivering feed to small animals in the separated spaces inside the incubator 11. The transparent plug plate can be inserted into the plug slot 17 to separate the culture space inside the incubator 11.

[0032] Example 2: A filter is installed at the lower end of the interior of the incubator 11, and a feed trough is fixedly connected to the surface of the filter. The feed trough is used to receive feed delivered through the feed delivery structure 4. A collection box 2 is slidably connected to the lower end of the interior of the incubator 11. The filter filters the feces of the small animals inside the incubator 11 and drops them into the collection box 2 at the lower end for collection, making it convenient to clean the incubator 11.

[0033] When the feed is fed into the feed tank 41 and sealed, the feed tank 41 is first loaded with feed material and sealed. Then, by rotating the feeding handle 43, the gear 410 drives the gear block 49 to slide the baffle 44, exposing the feeding port 45, and the feed falls into the feeding trough at the bottom for the small animal to eat. After the feeding is completed, the handle is released and the baffle 44 returns to its original position under the reset elastic force of the second spring structure 48, sealing the feeding port 45 to prevent the feed from continuing to fall. When it is necessary to open the box cover 12 for operation, it is only necessary to pull the lock handle 35 to pull the lock card rod 36 out of the lock hole 31 to easily open the box cover 12. After closing the box cover 12, the lock structure 3 is always in the lock hole 31 through the force of the first spring structure 34 and the telescopic rod structure 33, ensuring that the small animal cannot push it open and escape. In addition, the design of the filter screen and collection box 2 inside the incubator 11 makes cleaning convenient. This process not only improves the convenience of operation and experimental safety, but also maintains the stability of the internal environment of the incubator 11, thereby improving the efficiency of feeding management.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
