Description

Technical Field

[0001] This utility model relates to the field of test rack technology, and in particular to a live test rack device. Background Technology

[0002] With the rapid development of biomedical research, drug development, and toxicity testing, in vivo experiments (such as dynamic testing of animal models, organ cultures, or live cell samples) have become a core component of scientific research and technological verification. In vivo testing racks, as key equipment supporting experimental operations, directly affect the accuracy of experimental data, sample viability, and testing efficiency.

[0003] In traditional live-body testing fixtures, test probes are held by metal clamping components. However, the clamping force between the metal clamp and the test probe is difficult to control. Either the clamping is too loose, causing the test probe to tilt after movement, or the clamping is too tight, damaging the test probe and making it inconvenient to use. Therefore, we propose a live-body testing fixture device to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a live test fixture device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a base, on which a motion frame is fixedly mounted; on the motion frame, a connecting seat is fixedly mounted; on the connecting seat, a limiting tube is fixedly mounted; a threaded rod is provided on the inner side of the limiting tube; a loading sleeve is provided on the outer side of the limiting tube and the threaded rod; a top-holding seat is fixedly mounted on the inner side of the loading sleeve; a top-holding mechanism is provided on the top-holding seat; a plug-in seat is threadedly installed at the bottom of the loading sleeve; a test needle is provided on the inner side of the plug-in seat; and a gasket is sleeved on the test needle.

[0006] As a preferred embodiment, a first loading seat is fixedly provided at the bottom of the limiting tube, and a second loading seat is fixedly provided at the bottom of the threaded rod. A connecting mechanism is provided on the first loading seat and the second loading seat.

[0007] As a preferred embodiment, the connecting mechanism includes a first movable plate rotatably disposed on a first loading seat, a second movable plate rotatably disposed on a second loading seat, the first movable plate and the second movable plate being rotatably connected, a top holding plate being rotatably disposed at the end of the first movable plate away from the first loading seat, and the end of the second movable plate away from the second loading seat being rotatably connected to the top holding plate, the top holding plate cooperating with the loading sleeve.

[0008] As a preferred embodiment, the threaded rod is provided with threads, the threads are threadedly connected to the limiting tube, and the threaded rod passes through the limiting tube.

[0009] As a preferred embodiment, the supporting mechanism includes a reserved groove and a snap-fit ​​groove opened on the side of the supporting seat near the plug-in seat. An elastic pad is provided on the inner side of the reserved groove, and a snap-fit ​​ring is snapped into the inner side of the snap-fit ​​groove. The elastic pad is fixed on the snap-fit ​​ring.

[0010] As a preferred embodiment, a mounting bracket is fixedly mounted on the top of the base, and a vessel is fixedly mounted on the top of the mounting bracket.

[0011] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0012] The motion frame fixed on the base of this device is a three-axis motion platform, which can achieve displacement in three directions during use, making the testing of live subjects more convenient and flexible.

[0013] The top support fixedly installed on the inner side of the loading sleeve is used to load the top support mechanism. The top support mechanism installed on the top support, together with the plug-in seat, can stably load the test needle based on the basic principle of two points determining a straight line. This prevents the test needle from tilting during the live test and avoids direct contact between the test needle and the metal clamping parts, thus making the device easier to use.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0022] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0023] Please see Figures 1 to 5 This utility model provides a live body testing rack device, including a base 1, a motion frame 2 fixedly mounted on the base 1, a connecting seat 3 fixedly mounted on the motion frame 2, a limiting tube 4 fixedly mounted on the connecting seat 3, a threaded rod 5 provided on the inner side of the limiting tube 4, a loading sleeve 12 provided on the outer side of the limiting tube 4 and the threaded rod 5, a top holding seat 13 fixedly mounted on the inner side of the loading sleeve 12, a top holding mechanism provided on the top holding seat 13, a plug-in seat 18 threadedly mounted on the bottom of the loading sleeve 12, a test needle 19 provided on the inner side of the plug-in seat 18, and a sleeve pad 22 fitted on the test needle 19. In use, the base 1 serves as the supporting component for live body testing, providing a foundation for stable operation. The motion frame 2 fixedly mounted on the base 1 is a three-axis motion platform, capable of displacement in three directions during use, thus making live body testing more convenient and flexible.

[0024] The connecting seat 3 fixedly mounted on the motion frame 2 is used to support the limiting tube 4 and the motion frame 2, allowing the motion frame 2 to drive the limiting tube 4 to move flexibly. This improves the convenience of live animal testing. The limiting tube 4 fixedly mounted on the connecting seat 3 is used to load and connect the threaded rod 5. The threaded rod 5 on the inner side of the limiting tube 4 can move up and down inside the limiting tube 4, and the two are connected by threads. When neither part is rotated, the relative position of the limiting tube 4 and the threaded rod 5 remains stationary. The loading sleeve 12 on the outer side of the limiting tube 4 and the threaded rod 5 is the bearing component of the test needle 19. During use, it can prevent the test needle from directly contacting the metal parts that clamp it. Generally, in traditional live animal testing frames, the test needle is clamped by metal clamping components. However, the clamping force between the metal clamp and the test needle is not easy to control. Either the clamping is too loose, causing the test needle to tilt after movement, or the clamping is too tight, damaging the test needle and making it inconvenient to use. The top support seat 13 fixedly set on the inner side of the loading sleeve 12 is used to load the top support mechanism. The top support mechanism set on the top support seat 13, together with the plug seat 18, can stably load the test needle 19 based on the principle that two points determine a straight line. This prevents the test needle 19 from tilting during the live test and avoids direct contact between the test needle 19 and the metal clamping parts, making the device easier to use. The test needle 19 set on the inner side of the plug seat 18 is a test needle for live testing of microorganisms, etc. The sleeve 22 fitted on the test needle 19 is located between the top support seat 13 and the plug seat 18 in this device and abuts against the plug seat 18 to ensure the stability of the test needle 19 after loading.

[0025] Please see Figures 1 to 5 A first loading seat 7 is fixedly installed at the bottom of the limiting tube 4, and a second loading seat 8 is fixedly installed at the bottom of the threaded rod 5. A connecting mechanism is provided on the first loading seat 7 and the second loading seat 8. When this device is in use, the first loading seat 7 fixedly installed at the bottom of the limiting tube 4 is used to load the first movable plate 9, and the second loading seat 8 fixedly installed at the bottom of the threaded rod 5 is used to load the second movable plate 10. The connecting mechanism provided on the first loading seat 7 and the second loading seat 8 expands or contracts the distance between the first loading seat 7 and the second loading seat 8 when the threaded rod 5 is rotated. When the distance between the first loading seat 7 and the second loading seat 8 increases due to the rotation of the threaded rod 5, the connecting mechanism contracts, causing the contraction mechanism to separate from the loading sleeve 12. Conversely, when the distance between the first loading seat 7 and the second loading seat 8 decreases due to the rotation of the threaded rod 5, the connecting mechanism expands, causing the contraction mechanism to engage with the loading sleeve 12.

[0026] Please see Figures 1 to 5The connecting mechanism includes a first movable plate 9 rotatably disposed on the first loading seat 7, a second movable plate 10 rotatably disposed on the second loading seat 8, the first movable plate 9 and the second movable plate 10 being rotatably connected, a top holding plate 11 being rotatably disposed at the end of the first movable plate 9 away from the first loading seat 7, and the end of the second movable plate 10 away from the second loading seat 8 being rotatably connected to the top holding plate 11, and the top holding plate 11 cooperating with the loading sleeve 12. When this device is in use, the connecting mechanism includes a first movable plate 9 rotatably mounted on the first loading seat 7, which, together with a second movable plate 10 rotatably mounted on the second loading seat 8, allows the top holding plate 11 to be connected to both, thereby reducing or increasing the distance between the top holding plate 11 and the loading sleeve 12. This controls the easy separation and connection between the top holding plate 11 and the loading sleeve 12, facilitating the replacement of the test needle 19. The top holding plate 11, rotatably mounted on the end of the first movable plate 9 away from the first loading seat 7, is made of rubber and spreads outward from the center of the loading sleeve 12 to uniformly support the loading sleeve 12. The end of the second movable plate 10 away from the second loading seat 8 is rotatably connected to the top holding plate 11.

[0027] Please see Figures 1 to 5 The threaded rod 5 is provided with a thread 6, which is threadedly connected to the limiting tube 4, and the threaded rod 5 passes through the limiting tube 4. When this device is in use, the thread 6 provided on the threaded rod 5 is used for the threaded connection between the threaded rod 5 and the limiting tube 4.

[0028] Please see Figures 1 to 5 The supporting mechanism includes a reserved groove 14 and a snap-fit ​​groove 15 on the side of the supporting base 13 near the plug-in base 18. An elastic pad 17 is provided on the inner side of the reserved groove 14, and a snap-fit ​​ring 16 is snapped onto the inner side of the snap-fit ​​groove 15. The elastic pad 17 is fixed to the snap-fit ​​ring 16. When this device is in use, the reserved groove 14 on the side of the supporting base 13 near the plug-in base 18 is used to load the elastic pad 17, and the snap-fit ​​groove 15 is used to load the snap-fit ​​ring 16. The elastic pad 17 provided on the inner side of the reserved groove 14 is used to support the test needle 19, so that the test needle 19 remains stable during use and prevents tilting. The snap-fit ​​ring 16 snapped onto the inner side of the snap-fit ​​groove 15 is used to fix the elastic pad 17.

[0029] Please see Figures 1 to 5 A mounting frame 20 is fixedly installed on the top of the base 1, and a container 21 is fixedly installed on the top of the mounting frame 20. When this device is in use, the mounting frame 20 fixedly installed on the top of the base 1 is used to load and fix the container 21, and the container 21 fixedly installed on the top of the mounting frame 20 is used to hold live microorganisms.
