Description

Technical Field

[0001] The utility model belongs to the technical field of animal experimental equipment, and particularly relates to a mobile non-human primate weighing device. Background Art

[0002] Non-human primates share many biological and behavioral traits with humans, and therefore play a crucial role in research activities related to human biology, disease, drug development, and experimental animal science. As pharmaceutical development and preclinical testing continue to deepen, the demand for non-human primates as laboratory animals is also increasing.

[0003] Non-human primate laboratory animals must be regularly weighed in accordance with relevant management standards while in the vivarium. Accurate weighing data is crucial to understanding the general health of the animals and, in turn, to assessing the effects of test drugs on their health. Current weighing systems primarily utilize cages. Workers transfer non-human primates to cages, secure them, and then place them on a scale for weighing. However, cages are difficult to move, making them prone to escape during transfer. Furthermore, the cages themselves are bulky and difficult to move, and during transfer, animals can struggle due to stress, leading to injury and unstable data. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a mobile non-human primate weighing device with a simple structure, reasonable design, open frame structure, easy to fix animals, and high mobility performance due to the universal wheels.

[0005] Technical Solution: To achieve the above-mentioned purpose, the present invention provides a mobile non-human primate weighing device, comprising a bottom frame, a base, a bracket, and an operating platform. The base is detachably mounted on the bottom frame, the bracket is mounted on the base, and the operating platform is mounted on the upper portion of the bracket. The base can be placed on a scale after being disassembled.

[0006] The bracket includes a connecting square tube, at least one set of grab bars, and a mounting bracket. The bottom of the connecting square tube is connected to the base, the grab bars are located in the middle of the connecting square tube, and the mounting bracket is located at the top of the connecting square tube. The grab bar design is consistent with the gripping reflexes of non-human primates that prefer climbing and in stressful situations, ensuring more stable operation and faster adaptation during weighing.

[0007] Furthermore, the operating platform includes a collar mounting plate and an acrylic plate. The acrylic plate is mounted on the collar mounting plate. A first chute and a second chute are provided on the side of the collar mounting plate. A collar is slidably mounted in one of the first and second chute. The collar can slide in the first and second chute and be secured to the weighing device via a latch. The chute sizes vary depending on the size of the collar being used.

[0008] Furthermore, the collar is provided with a locking hole, and the mounting bracket is provided with a pair of pin holes. Double pins are inserted into the pin holes through the locking hole. Blocks are provided in the first and second chutes. The double pin design prevents the animal from accidentally escaping and makes operation safer for personnel. The block limits the collar's position, preventing the collar from being pushed forward too far and causing injury to the animal.

[0009] Furthermore, the base comprises a frame formed by four intersecting square tubes, with a crossbeam disposed in the middle of the frame. A connecting sleeve is vertically mounted on the crossbeam. The connecting sleeve has multiple pin holes disposed around its perimeter, and the bottom of the connecting square tube has a pin hole. The connecting square tube and the connecting sleeve are connected via a latch. The pin holes at the bottom of the connecting square tube cooperate with pin holes at different heights on the connecting sleeve to adjust the height of the bracket. By rotating the connecting square tube, the bracket and the structure above it can be adjusted in direction to accommodate operational requirements in different spaces.

[0010] Furthermore, the bottom frame is provided with a bottom sleeve, which is provided with a locking bolt. The end of the square tube extends downward, is inserted into the bottom sleeve, and is locked by the locking bolt. After the base is separated from the bottom frame, the downwardly extending end of the square tube can be snapped onto the scale, improving stability during weighing.

[0011] Furthermore, the bottom of the bottom frame is provided with universal wheels, which can be easily moved. The edge of the bottom frame is provided with anti-collision adhesive tape.

[0012] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0013] 1. The present invention provides a mobile non-human primate weighing device with an open frame structure, which makes it easy to secure primate experimental animals to the device. Universal wheels are provided on the lower part of the bottom frame to facilitate the movement of the entire device. The bottom frame and the base are connected by bolts. After the two are disassembled, the base can be locked with the scale to ensure stability during the weighing process.

[0014] 2. In the utility model, the bracket and the base are connected by a connecting square tube and a connecting sleeve. The connecting square tube is inserted into the connecting sleeve to adjust the bracket up and down and adjust the angles of 90° and 180°, which is suitable for operations in various space environments.

[0015] 3. The present invention is also provided with an operating platform, which is arranged on the bracket and can be used to store items during operation for easy access; the neck collar mounting plate is provided with a double-layer slide groove to accommodate neck collars of different specifications; a grab bar is provided on the bracket to meet the non-human primate's preference for climbing and grasping reaction in stressful situations, making the operation process more stable or quickly adapting during weighing.

[0016] 4. The utility model has a simple structure, is easy to clean and disinfect, and prevents microbial infection. BRIEF DESCRIPTION OF THE DRAWINGS
