Description

Technical Field

[0001] This invention relates to the field of animal laboratory cage technology, specifically a multi-layer laboratory animal cage that is easy to disassemble and its usage method. Background Technology

[0002] Laboratory animal cages are containers specifically designed for raising laboratory animals in a laboratory environment. Their main purpose is to provide laboratory animals with a safe, comfortable living space that meets experimental requirements, while also facilitating researchers' observation, handling, and management of the animals. These animals include a variety of commonly used laboratory animal species such as mice, rats, guinea pigs, and rabbits. Ordinary cages are mainly used for the daily raising of laboratory animals.

[0003] Chinese patent CN221488662U discloses a laboratory animal rearing cage comprising multiple cage bodies that can be sequentially assembled vertically to reduce floor space. Each cage body consists of a frame, four side frames, a bottom frame, and a top plate. The four side frames are respectively snapped into the inner walls of the frame, the top plate is fixed to the top of the frame, and the bottom frame is snapped between the four side frames to form the cage body. A feeder is located on the front side frame for holding food, and one side of the feeder extends into the cage body for guiding the food. A blocking plate is located on one side of the front side frame and is interchangeable with the feeder for sealing the side frame. A fixing mechanism is located on the front side frame for fixing the feeder and the blocking plate. Positioning holes are provided at the four corners of the top of the frame. By making the frame detachable, it allows for easy disinfection and cleaning of the entire interior, and also makes it convenient to place pets inside. The frame can be joined vertically to effectively reduce its footprint, and the bottom frame filters feces to prevent them from sticking to the pet.

[0004] However, the technical solution of this patent has the following problems:

[0005] 1. This patent makes the frame detachable, which allows for easy disinfection and cleaning of the entire cage and also makes it easy to put the pet inside. The frame can be spliced ​​up and down to effectively reduce the space occupied. At the same time, the bottom frame can filter feces to prevent feces from sticking to the pet. However, when cleaning the bottom frame, the animal needs to be taken out of the cage, which is inconvenient.

[0006] 2. This patent only allows water to be added to each cage individually, and does not allow for quick replacement and cleaning of the feeding trough.

[0007] Based on this, the present invention designs a multi-layer laboratory animal breeding cage that is easy to disassemble and its usage method to solve the above problems. Summary of the Invention

[0008] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a multi-layer laboratory animal breeding cage that is easy to disassemble and a method of using it.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0017] Furthermore, an electric valve is installed on the right side of the irregularly shaped water tank, a water trough is fixedly installed on the right side of the left baffle, and the output end of the electric valve is located above the water trough.

[0018] Furthermore, the feeding trough replacement device includes: a support frame, a feeding trough, and an isolation net. The support frame is fixedly installed on the right side of the bottom shell, the feeding trough is slidably connected to the support frame, and there is damping when the feeding trough slides on the support frame. The isolation net is hinged to the lower side of the right metal mesh via a hinge.

[0019] Furthermore, a connecting shell is fixedly installed on the upper side of the left baffle. The connecting shell is fixedly installed on the upper side of the rear metal mesh and the right metal mesh. The connecting shell is provided with multiple strip slots, which are used to accommodate square foot supports, so that the equipment can be stacked quickly.

[0020] Both the dual-output shaft motor and the electric valve are electrically connected to an external controller.

[0021] To better achieve the objectives of this invention, the present invention also provides a method for using a multi-layer laboratory animal rearing cage that is easy to disassemble, comprising the following steps:

[0022] Step 1: Stack the equipment as needed, place the square support of the upper equipment into the strip slot of the connecting shell of the lower equipment, and at the same time, the quick connector of the lower connecting pipe of the upper equipment can be inserted into the quick connector of the upper connecting pipe of the lower equipment to connect the irregular water tanks of the stacked equipment to form a whole.

[0023] Step 2: Open the buckle on the right side of the front metal mesh. Place the animal on the bottom metal mesh, close the front metal mesh and the buckle at the same time, rotate the isolation net to open it, add food to the feeding trough, close the isolation net, open the water inlet valve of the top device, and add water to the irregular water tank of the top device. This will add water to all the devices below it.

[0024] Step 3: To clean the feeding trough, pull it out towards the support frame away from the feeding trough replacement device and replace it with a new one. To replace the manure trough, open the rotating plate, pull out the manure trough, and replace it with a new one. To replace the bottom frame metal mesh, slide the new bottom frame metal mesh into the irregularly shaped base under the old bottom frame metal mesh, pull out the old bottom frame metal mesh, and the external controller will start the dual-output shaft motor. The output shaft of the dual-output shaft motor rotates, driving the first bevel gear to rotate. The first bevel gear rotates, driving the second bevel gear to rotate. The second bevel gear rotates, driving the upper drive shaft of the lifting assembly to rotate. The upper drive shaft rotates, driving the sprocket on the upper drive shaft to rotate. The rotation of the sprocket on the upper drive shaft drives the sprocket on the lower drive shaft to rotate through the chain. The chain rotation drives the irregularly shaped base to move upward, which in turn moves the new bottom frame metal mesh upward until it reaches the height of the old bottom frame metal mesh. This allows you to replace the bottom frame metal mesh without moving the animals inside the equipment.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention allows a new bottom frame metal mesh to be slidably inserted into the irregularly shaped base on the lower side of the old bottom frame metal mesh, and the old bottom frame metal mesh to be pulled out. The external controller controls the start of the dual-output shaft motor. The output shaft of the dual-output shaft motor rotates, which drives the first bevel gear to rotate. The first bevel gear rotates, which drives the second bevel gear to rotate. The second bevel gear rotates, which drives the upper transmission shaft of the lifting assembly to rotate. The upper transmission shaft rotates, which drives the sprocket on the upper transmission shaft to rotate. The rotation of the sprocket on the upper transmission shaft drives the sprocket on the lower transmission shaft to rotate through the chain. The rotation of the chain drives the irregularly shaped base to move upward. The upward movement of the irregularly shaped base drives the new bottom frame metal mesh to move upward. The new bottom frame metal mesh stops moving at the height of the old bottom frame metal mesh. This is beneficial for replacing the bottom frame metal mesh without transferring the animals inside the equipment.

[0026] 2. By stacking the equipment on top of each other, the quick connector of the lower connecting pipe of the water supply device of the upper equipment can be inserted into the quick connector of the upper connecting pipe of the lower equipment, so that the irregular water tanks of the upper and lower equipment are connected. By adding water to the uppermost equipment, all the equipment below it can be filled with water. The electric valve is opened and closed by an external controller. When the electric valve is opened, the water in the irregular water tank is placed into the water tank, and water can be provided to the animals regularly.

[0027] 3. The feeding trough can be replaced by pulling it out of the support frame away from the feeding trough replacement device. This facilitates quick replacement or cleaning of the feeding trough without the need to transfer the animals inside the equipment. Multiple devices can be stacked by placing the square legs of the upper device into the slots of the connecting shell of the lower device. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] The present invention will be further described below with reference to embodiments.

[0040] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0041] Example 1: In some examples, please refer to Figures 1-7 A multi-layer laboratory animal cage that is easy to disassemble includes a bottom shell 1. Multiple square legs 2 are fixedly installed on the lower side of the bottom shell 1. A lifting and changing device 3 is installed on the upper side of the bottom shell 1. An animal placement device 4 is installed on the upper side of the lifting and changing device 3. A water supply device 5 is installed on the left side of the animal placement device 4. A feed trough changing device 6 is installed on the right side of the animal placement device 4. The lifting and changing device 3 includes a manure trough 31, a lifting mechanism, and a rotating plate 32. The manure trough 31 is slidably connected to the upper side of the bottom shell 1. The lifting mechanism is installed on the left and right sides of the bottom shell 1. The rotating plate 32 is rotatably connected to the front side of the bottom shell 1 via a rotating shaft.

[0042] By raising the replacement device 3, the manure trough 31 can be quickly replaced without removing the animal from the feeding cage. The animal placement device 4 is used to place the animal. The water supply device 5 can connect the water sources of multiple devices. Simply adding water to the water supply device 5 of the top device will add water to all the devices below it. The feed trough 62 can be quickly replaced or cleaned by the feed trough replacement device 6.

[0043] The lifting mechanism includes a lifting component, a bottom frame metal mesh 33, and a driving component. The two lifting components are respectively installed on the left and right sides of the bottom shell 1. The bottom frame metal mesh 33 is installed on the lifting components and facilitates the falling of animal feces. The driving component is installed on the rear side of the two lifting components.

[0044] Animal feces fall into the manure trough 31 through the bottom frame metal mesh 33. Animal feces inevitably get on the bottom frame metal mesh 33. When cleaning the bottom frame metal mesh 33 with conventional equipment, the animals inside the equipment need to be transferred before the bottom frame metal mesh 33 can be cleaned. The present invention replaces the old bottom frame metal mesh 33 by inserting a new bottom frame metal mesh 33 under the bottom frame metal mesh 33 of the lifting component. The lifting component is driven by the drive component to lift the new bottom frame metal mesh 33 to the height of the old bottom frame metal mesh 33, so that the bottom frame metal mesh 33 can be replaced without transferring the animals inside the equipment.

[0045] The lifting assembly includes an upper drive shaft 34, a lower drive shaft 35, sprockets 36, a chain 37, and irregularly shaped bases 38. The upper drive shaft 34 is rotatably connected to the upper left side of the bottom shell 1, and the lower drive shaft 35 is rotatably connected to the lower left side of the bottom shell 1. Sprockets 36 are fixedly installed on both the front and rear sides of the upper drive shaft 34 and the lower drive shaft 35. The front sprockets 36 of the upper drive shaft 34 and the front sprockets 36 of the lower drive shaft 35 are connected by the chain 37. The rear sprockets 36 of the upper drive shaft 34 and the rear sprockets 36 of the lower drive shaft 35 are also connected by the chain 37. Multiple irregularly shaped bases 38 are fixedly installed on the end of the chain 37 away from the sprockets 36, and the distance between each adjacent irregularly shaped base 38 on the chain 37 is the same.

[0046] The bottom frame metal mesh 33 is slidably connected to the irregularly shaped base 38.

[0047] The drive assembly includes a dual-output shaft motor 39, a first bevel gear 310, and a second bevel gear 311. The dual-output shaft motor 39 is fixedly mounted on the rear side wall of the bottom shell 1 via a motor bracket. The two first bevel gears 310 are rotatably connected to the rear side wall of the bottom shell 1 via a rotating shaft. The end of the rotating shaft of each first bevel gear 310 away from the first bevel gear 310 is fixedly connected to the output shaft of the dual-output shaft motor 39 via a coupling. A second bevel gear 311 is fixedly mounted on the rear side of the upper drive shaft 34 of each lifting assembly. Adjacent first bevel gears 310 and second bevel gears 311 mesh with each other.

[0048] A new bottom frame metal mesh 33 is slidably inserted into the irregularly shaped base 38 below the old bottom frame metal mesh 33. The old bottom frame metal mesh 33 is then pulled out. The external controller starts the dual-output shaft motor 39. The output shaft of the dual-output shaft motor 39 rotates, driving the first bevel gear 310 to rotate. The first bevel gear 310 rotates, driving the second bevel gear 311 to rotate. The second bevel gear 311 rotates, driving the upper drive shaft 34 of the lifting assembly to rotate. The upper drive shaft 34 rotates, driving the sprocket 36 on the upper drive shaft 34 to rotate. The rotation of the sprocket 36 on the upper drive shaft 34 drives the sprocket 36 on the lower drive shaft 35 to rotate via the chain 37. The rotation of the chain 37 drives the irregularly shaped base 38 to move upward. The upward movement of the irregularly shaped base 38 drives the new bottom frame metal mesh 33 to move upward. The new bottom frame metal mesh 33 stops when it reaches the height of the old bottom frame metal mesh 33. This facilitates the replacement of the bottom frame metal mesh 33 without transferring the animals inside the equipment.

[0049] Example 2: In some embodiments, such as Figures 1-7 As shown, in a preferred embodiment of the present invention, the animal placement device 4 includes: a left baffle 41, a rear metal mesh 42, a right metal mesh 43, and a front metal mesh 44. The left baffle 41 is fixedly installed on the left side of the bottom shell 1. The left side of the rear metal mesh 42 is fixedly installed on the rear side of the left baffle 41, and the lower side of the rear metal mesh 42 is fixedly installed on the upper side of the bottom shell 1. The rear side of the right metal mesh 43 is fixedly installed on the right side of the rear metal mesh 42. The left side of the front metal mesh 44 is hinged to the front side of the left baffle 41 by a hinge, and the right side of the front metal mesh 44 is snapped to the front side of the right metal mesh 43 by a buckle.

[0050] Open the buckle on the right side of the front metal mesh 44, then open the front metal mesh 44 and place the animal on the bottom frame metal mesh 33. The left baffle 41, the rear metal mesh 42, the right metal mesh 43 and the front metal mesh 44 restrict the animal's range of movement, and the rear metal mesh 42, the right metal mesh 43 and the front metal mesh 44 provide the animal with a high degree of ventilation.

[0051] The water supply device 5 includes: a shaped water tank 51, a lower connecting pipe 52, an upper connecting pipe 53, and an inlet valve 54. The shaped water tank 51 is fixedly installed on the left side wall of the left baffle 41. The lower connecting pipe 52 is fixedly installed on the lower rear side of the shaped water tank 51. The upper connecting pipe 53 is fixedly installed on the upper rear side of the shaped water tank 51. A quick connector 55 is fixedly installed at the end of the lower connecting pipe 52 away from the shaped water tank 51. A quick connector 56 is fixedly installed at the end of the upper connecting pipe 53 away from the shaped water tank 51. The inlet valve 54 is fixedly installed on the front side of the shaped water tank 51.

[0052] An electric valve 57 is installed on the right side of the irregularly shaped water tank 51, and a water trough 58 is fixedly installed on the right side of the left baffle 41. The output end of the electric valve 57 is located above the water trough 58.

[0053] When the equipment is stacked, the quick connector 55 of the lower connecting pipe 52 of the water supply device 5 of the upper equipment can be inserted into the quick connector 56 of the upper connecting pipe 53 of the lower equipment, so that the irregular water tank 51 of the upper and lower equipment are connected. By adding water to the uppermost equipment, water can be added to all the equipment below it. The electric valve 57 is opened and closed by the external controller. When the electric valve 57 is opened, the water in the irregular water tank 51 is placed into the water tank 58, so that water can be provided to the animals regularly.

[0054] The feeding trough replacement device 6 includes: a support frame 61, a feeding trough 62, and an isolation net 63. The support frame 61 is fixedly installed on the right side of the bottom shell 1. The feeding trough 62 is slidably connected to the support frame 61. The feeding trough 62 has damping when sliding on the support frame 61. The isolation net 63 is hinged to the lower side of the right metal mesh 43 by a hinge.

[0055] To add food, rotate the isolation net 63 to open it, add food to the feeding trough 62, and close the isolation net 63. To clean the feeding trough 62, pull the feeding trough 62 away from the support frame 61 of the feeding trough replacement device 6 and replace it with a new feeding trough 62. This facilitates quick replacement or cleaning of the feeding trough 62 without the need to transfer the animals inside the equipment.

[0056] A connecting shell 7 is fixedly installed on the upper side of the left baffle 41. The connecting shell 7 is fixedly installed on the upper side of the rear metal mesh 42 and the right metal mesh 43. The connecting shell 7 is provided with multiple strip slots 8, which are used to accommodate square foot supports 2, so that the equipment can be stacked quickly.

[0057] By placing the square foot support 2 of the upper device into the strip slot 8 of the connecting shell 7 of the lower device, multiple devices can be stacked. At the same time, the quick connector 55 of the lower connecting pipe 52 of the upper device can be inserted into the quick connector 56 of the upper connecting pipe 53 of the lower device, so as to connect the irregularly shaped water tanks 51 of the upper and lower devices.

[0058] Example 3: In some embodiments, such as Figures 1-7 As shown, in a preferred embodiment of the present invention, a method for easily disassembled multi-layer laboratory animal rearing cages includes the following steps:

[0059] Step 1: Stack the equipment as needed, placing the square support 2 of the upper equipment into the slot 8 of the connecting shell 7 of the lower equipment. Simultaneously, the quick connector 55 of the lower connecting pipe 52 of the upper equipment can be inserted into the quick connector 56 of the upper connecting pipe 53 of the lower equipment, connecting the stacked equipment's irregularly shaped water tank 51 to form a single unit.

[0060] Step 2: Open the buckle on the right side of the front metal mesh 44. Place the animal on the bottom frame metal mesh 33, close the front metal mesh 44 and the buckle, rotate the isolation net 63 to open it, add food to the feeding trough 62, close the isolation net 63, open the water inlet valve 54 of the uppermost device, add water to the irregular water tank 51 of the uppermost device, and then add water to all the devices below it.

[0061] Step 3: To clean the feeding trough 62, pull the feeding trough 62 away from the support frame 61 of the feeding trough replacement device 6 and replace it with a new feeding trough 62. To replace and clean the manure trough 31, open the rotating plate 32, pull out the manure trough 31, and replace it with a new manure trough 31. To replace and clean the bottom frame metal mesh 33, slide the new bottom frame metal mesh 33 into the irregularly shaped base 38 on the underside of the old bottom frame metal mesh 33, pull out the old bottom frame metal mesh 33, and the external controller controls the dual-output shaft motor 39 to start. The output shaft of the dual-output shaft motor 39 rotates, driving the first bevel gear 310 to rotate. The rotation of wheel 310 drives the second bevel gear 311 to rotate, which in turn drives the upper drive shaft 34 of the lifting assembly to rotate. The rotation of the upper drive shaft 34 drives the sprocket 36 on the upper drive shaft 34 to rotate. The rotation of the sprocket 36 on the upper drive shaft 34 drives the sprocket 36 on the lower drive shaft 35 to rotate via chain 37. The rotation of chain 37 drives the irregularly shaped base 38 to move upward. The upward movement of the irregularly shaped base 38 drives the new bottom frame metal mesh 33 to move upward. The movement stops when the new bottom frame metal mesh 33 reaches the height of the old bottom frame metal mesh 33, allowing the bottom frame metal mesh 33 to be replaced without transferring the animals inside the equipment.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
