Description

Technical Field

[0001] This utility model relates to the field of staining instrument technology, and in particular to a sealing structure for a fully automated immunohistochemical staining instrument. Background Technology

[0002] A staining instrument is an instrument used to stain biological samples (such as cell smears, tissue sections, etc.) or other materials. A fully automated immunohistochemical staining instrument is a special type of staining instrument. It is specifically used for immunohistochemical staining, which is a technique that uses the specific binding reaction of antigen and antibody and locates antigens in tissue cells through color development.

[0003] In the current market, the operation of fully automated immunohistochemical staining instruments relies on external pipelines to deliver reagents and cleaning solutions, and it is essential to ensure that these pipelines have excellent sealing performance to prevent leakage during transmission. In traditional technology, independent sealing gaskets are usually used to seal the delivery pipelines. However, after long-term use, due to machine vibration or external contact, the sealing gaskets are prone to displacement, which will negatively affect the sealing effect of the pipelines. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the sealing gasket used alone cannot achieve a good sealing effect. To this end, we propose a sealing structure for a fully automated immunohistochemical staining instrument.

[0005] To achieve the above objectives, this application adopts the following technical solution: a sealed structure for a fully automated immunohistochemical staining instrument, comprising a device base, a top outer shell mounted on the top of the device base, a staining device body mounted on the top of the device base, a connecting pipe fixedly connected to one side of the device base, a fixing block fixedly connected to the front end of the device base, an adjusting rod slidably connected inside the fixing block, several limiting grooves provided at both the front and rear ends of the adjusting rod, a handle fixedly connected to one side of the adjusting rod, a shaped plate fixedly connected to the other side of the adjusting rod, a conveying pipe fixedly connected inside the shaped plate, several sealing gaskets mounted on the surface of the conveying pipe, sliding grooves provided at both the top and bottom ends inside the fixing block, a sliding rod slidably connected inside the sliding grooves, a push-pull plate fixedly connected to the end of the sliding rod away from the fixing block, a spring spring slidably connected to the surface of the sliding rod, the end of the spring spring near the push-pull plate fixedly connected to the push-pull plate, and the end of the spring spring away from the push-pull plate fixedly connected to the surface of the fixing block.

[0006] Preferably, the front and rear ends of the fixed block are provided with first sliding grooves, and the front and rear ends of the adjusting rod are fixedly connected with first sliders, and the interior of the first sliding groove is slidably connected to the first slider.

[0007] Preferably, a second sliding groove is provided on both sides of the inside of the fixed block, and a second slider is fixedly connected to both sides of the sliding rod, with the inside of the second sliding groove slidably connected to the second slider.

[0008] Preferably, the surface of the sliding rod is provided with an inclined surface, and the sliding rod is used in conjunction with the limiting groove.

[0009] Preferably, a return spring is fixedly connected to the side of the handle near the fixed block, and there are two return springs, with the end of the return spring near the fixed block being fixedly connected to the fixed block.

[0010] Preferably, the sealing gasket is made of a nano-ceramic polymer material.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, when the worker needs to install the conveying pipe, the push-pull plate is pulled to both sides, causing the sliding rod to be pulled out of the limiting groove, thus releasing the limiting position of the adjusting rod. At this time, the conveying pipe is moved into the interior of the connecting pipe, and the sealing gasket is fully in contact with the interior of the connecting pipe, forming the limiting position of the conveying pipe. Then, the push-pull plate is released, and the elastic force of the spring drives the sliding rod to return to the interior of the limiting groove, so that the adjusting rod and the conveying pipe are synchronously limited, thereby achieving auxiliary fixation when sealing the conveying pipe. By setting up auxiliary fixation when sealing the conveying pipe, the sealing gasket is less likely to be displaced due to external impact or machine vibration, thereby effectively improving the sealing effect between the conveying pipe and the connecting pipe. Moreover, the presence of multiple sealing gaskets further enhances the sealing effect. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a sealing structure for a fully automated immunohistochemical staining instrument, including a device base 1, a top outer shell 2 installed at the top of the device base 1, a staining device body 3 installed at the top of the device base 1, a connecting pipe 4 fixedly connected to one side of the device base 1, a fixing block 5 fixedly connected to the front end of the device base 1, an adjusting rod 6 slidably connected inside the fixing block 5, several limiting grooves 7 opened at both the front and rear ends of the adjusting rod 6, a handle 8 fixedly connected to one side of the adjusting rod 6, a shaped plate 9 fixedly connected to the other side of the adjusting rod 6, a conveying pipe 10 fixedly connected inside the shaped plate 9, several sealing gaskets 11 installed on the surface of the conveying pipe 10, sliding grooves 12 opened at both the top and bottom ends inside the fixing block 5, a sliding rod 13 slidably connected inside the sliding groove 12, a push-pull plate 14 fixedly connected to the end of the sliding rod 13 away from the fixing block 5, a spring spring 15 slidably connected to the surface of the sliding rod 13, and the spring spring 15 close to the push-pull plate. One end of the spring 14 is fixedly connected to the push-pull plate 14, and the end of the spring spring 15 away from the push-pull plate 14 is fixedly connected to the surface of the fixing block 5. When the worker needs to install the conveying pipe 10, the push-pull plate 14 is pulled to both sides, so that the sliding rod 13 is pulled out from the limiting groove 7, and the adjusting rod 6 is released from the limit. At this time, the conveying pipe 10 is moved into the interior of the connecting pipe 4, and the sealing gasket 11 is fully in contact with the interior of the connecting pipe 4, forming the limit of the conveying pipe 10. Then the push-pull plate 14 is released. At this time, the elastic force of the spring spring 15 drives the sliding rod 13 to return to the interior of the limiting groove 7, so that the adjusting rod 6 and the conveying pipe 10 are synchronously limited, thereby achieving the auxiliary fixation when the conveying pipe 10 is sealed. By setting the auxiliary fixation when the conveying pipe 10 is sealed, the sealing gasket 11 is not easily displaced by external impact or machine vibration, thereby effectively improving the sealing effect between the conveying pipe 10 and the connecting pipe 4. Moreover, multiple sealing gaskets 11 are provided, so that the sealing effect can be further improved.

[0021] Reference Figure 4 As shown in this embodiment: the front and rear ends of the fixed block 5 are provided with first sliding grooves 16, and the front and rear ends of the adjusting rod 6 are fixedly connected with first sliders 17. The interior of the first sliding groove 16 is slidably connected to the first slider 17. Through the setting of the first sliding groove 16 and the first slider 17, the adjusting rod 6 can form a stable guiding effect when moving, so that the adjusting rod 6 will not deviate when moving, thereby effectively ensuring the normal fixation of the adjusting rod 6 and the stability of the conveying pipe 10 when sliding into the connecting pipe 4, effectively improving the use effect.

[0022] Reference Figure 5 As shown in this embodiment: a second sliding groove 18 is provided on both sides of the inside of the fixed block 5, and a second slider 19 is fixedly connected to both sides of the sliding rod 13. The inside of the second sliding groove 18 is slidably connected to the second slider 19. Through the setting of the second sliding groove 18 and the second slider 19, the sliding rod 13 can form a stable limiting effect when sliding inside the sliding groove 12, thereby effectively preventing the sliding rod 13 from moving too much and causing adverse consequences, thereby affecting the normal fixing or normal release of the adjusting rod 6.

[0023] Reference Figure 4 As shown in this embodiment: the surface of the sliding rod 13 is provided with an inclined surface 20. The sliding rod 13 is used in conjunction with the limiting groove 7. With the setting of the inclined surface 20, when the operator needs to release the limit of the adjusting rod 6, he only needs to push the handle 8 forward to release the limit of the adjusting rod 6, thereby achieving the rapid release of the limit of the adjusting rod 6 and further improving the operating efficiency.

[0024] Reference Figure 5 As shown in this embodiment: a return spring 21 is fixedly connected to the side of the handle 8 near the fixed block 5. There are two return springs 21. The end of the return spring 21 near the fixed block 5 is fixedly connected to the fixed block 5. When the staff needs to disassemble the conveying pipe 10, the adjusting rod 6 is released from the limit and the conveying pipe 10 is pulled out. At this time, the elastic force of the return spring 21 can make the conveying pipe 10 return to the initial position, which makes it easier for the staff to carry out the next operation and effectively improves the user experience.

[0025] Reference Figure 3 As shown in this embodiment, the sealing gasket 11 is made of nano-ceramic polymer material. By using nano-ceramic polymer material to make the sealing gasket 11, the sealing gasket 11 can have better wear resistance and toughness, thereby effectively improving the service life and sealing effect of the sealing gasket 11.

[0026] Working principle: When the worker needs to install the conveying pipe 10, the push-pull plate 14 is pulled to both sides, causing the sliding rod 13 to be pulled out of the limiting groove 7, thus releasing the limiting position of the adjusting rod 6. At this time, the conveying pipe 10 is moved into the interior of the connecting pipe 4, and the sealing gasket 11 is fully in contact with the interior of the connecting pipe 4, forming the limiting position of the conveying pipe 10. Then the push-pull plate 14 is released, and the elastic force of the spring spring 15 drives the sliding rod 13 to return to the interior of the limiting groove 7, so that the adjusting rod 6 and the conveying pipe 10 are synchronously limited, thereby achieving the sealing of the conveying pipe 10. The auxiliary fixing mechanism helps to secure the conveying pipe 10 during sealing, preventing the sealing gasket 11 from shifting due to external impacts or machine vibrations. This effectively improves the sealing effect between the conveying pipe 10 and the connecting pipe 4. The presence of multiple sealing gaskets 11 further enhances the sealing effect. The first sliding groove 16 and the first slider 17 provide a stable guide for the adjusting rod 6 during movement, preventing it from shifting and ensuring its proper alignment. The stability of the conveying pipe 10 when it slides into the connecting pipe 4 is improved, thus enhancing the performance. The second sliding groove 18 and the second slider 19 allow the sliding rod 13 to slide within the sliding groove 12, forming a stable limiting effect. This effectively prevents the sliding rod 13 from moving too much and causing adverse consequences, thus affecting the normal fixing and unfixing of the adjusting rod 6. With the inclined surface 20, when the operator needs to release the limiting of the adjusting rod 6, they only need to push the handle 8 forward to release the limiting of the adjusting rod 6, thereby achieving quick release of the limiting of the adjusting rod 6 and further improving the operating efficiency. When the operator needs to disassemble the conveying pipe 10, the adjusting rod 6 is released and the conveying pipe 10 is pulled out. At this time, the elastic force of the return spring 21 can return the conveying pipe 10 to the initial position, making it easier for the operator to carry out the next operation and effectively improving the user experience. By using nano-ceramic polymer material to make the sealing gasket 11, the sealing gasket 11 can have better wear resistance and toughness, thereby effectively improving the service life and sealing effect of the sealing gasket 11.
