AI Technical Summary
The large space occupied by the dispensing needle in the pathological staining machine leads to an excessively large device size, and the shaking of the liquid tube causes unstable staining.
The liquid tube is stabilized by a fixed-head integrated drip needle and a staggered threaded connection hole and connection mechanism. The liquid tube is kept stable by a limiting structure of annular groove and rotating ring.
This reduces the space occupied by the device and ensures the stability of the liquid pipe during operation, avoiding pipe bending and improving the stability of drip dyeing.

Technical Field
[0001] This utility model relates to the field of drip pipelines, specifically a novel drip pipeline device. Background Technology
[0002] In pathological staining machines, the existing components used for dispensing are generally clamping dispensing needles. Each clamping dispensing needle occupies a considerable amount of space, and when multiple such needles are installed, the overall size of the device is quite large. As an integrated device, the staining machine will cause excessive occupation of the staining space. Furthermore, during the staining process, the liquid tube is prone to shaking, and excessive shaking can cause the liquid tube to bend, resulting in unstable staining. Utility Model Content

[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] 1. This application integrates multiple dripping needles onto a fixed head and uses an alternating design for the threaded connection holes, which can further reduce the space occupied by the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-4 In this embodiment of the utility model, a novel dripping pipeline device includes a mounting plate 1. A fixing head 2 is fixedly mounted on the bottom end of the mounting plate 1. Multiple dripping needles 3 are integrally formed on the bottom end of the fixing head 2. Multiple threaded mounting holes 11 that are alternately distributed at both ends of the mounting plate 1 and are connected to the top of the dripping needles 3 one by one. A liquid tube 4 is threadedly connected to the inner wall of the threaded mounting hole 11. A sealing ring is installed at the threaded connection between the liquid tube 4 and the threaded mounting hole 11. A connecting mechanism for limiting the liquid tube 4 is fixedly mounted on both sides of the mounting plate 1.
[0017] In this embodiment: when applying the stain to the glass slide, a micro liquid pump connected to the liquid tube 4 is started. The input end of one liquid tube 4 is connected to one micro liquid pump. The micro liquid pump introduces the staining agent through the liquid tube 4 into multiple dispensing needles 3. Finally, the staining agent is sprayed from the dispensing needles 3 onto the glass slide to stain the tissue section.
[0018] When installing the liquid pipe 4, first connect the end of the liquid pipe 4 with the hollow threaded head to the threaded mounting hole 11. During the connection process, the sealing ring is compressed and deformed, thereby improving the sealing performance of the connection. After the connection is completed, open the connecting mechanism and connect the liquid pipe 4 to the connecting mechanism. After the connection is completed, remove the force applied to the connecting mechanism. At this time, the connecting mechanism resets and suspends the liquid pipe 4, stabilizing the position of the liquid pipe 4 and preventing the liquid pipe 4 from shaking during operation. It is also more convenient to replace and install the liquid pipe 4 if it is damaged.
[0019] Please refer to this carefully. Figure 3 and Figure 4 The connecting mechanism includes connectors 5 fixedly connected to both sides of the bottom end of the mounting plate 1. The connectors 5 have annular grooves 8 with the same extension trajectory inside. One end of the annular groove 8 is open and the other end is closed. The vertical cross-section of the open structure of the annular groove 8 is convex. The connecting mechanism also includes a rotating ring 6 slidably connected to the inner cavity of the annular groove 8. One end of the rotating ring 6 extends through the inner cavity of the annular groove 8. An anti-detachment block 9 is integrally formed at the end of the rotating ring 6 located in the inner cavity of the annular groove 8. An outwardly protruding force-bearing protrusion 7 is integrally formed on the outer side of the end of the rotating ring 6 located outside the annular groove 8. An annular spring 10 is fixedly installed between the anti-detachment block 9 and the end of the inner wall of the annular groove 8.
[0020] In this embodiment: when installing or removing the liquid tube 4, a downward pushing force is applied to the force-bearing protrusion 7, which pushes the rotating ring 6 to slide along the inner wall of the annular groove 8. At this time, the rotating ring 6 drives the anti-detachment block 9 to squeeze the annular spring 10. The annular spring 10 is compressed, and the paper rotating ring 6 rotates open. Then, the liquid tube 4 is inserted into the lower inner wall of the connector 5. At this time, the force applied to the force-bearing protrusion 7 is removed, and the annular spring 10 begins to reset. The reset annular spring 10 pushes the anti-detachment block 9 to reset along the annular groove 8. The reset annular groove 8 pushes the rotating ring 6 to close until one end of the rotating ring 6 abuts against the closed end of the connector 5, thus completing the limiting and suspension of the liquid tube 4.
[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
