Description

Technical Field

[0001] This utility model relates to the field of adapter technology, and in particular to a novel anti-clogging syringe adapter. Background Technology

[0002] In syringe dispensing scenarios, a fixed back-suction pressure needs to be set to prevent glue from flowing out due to gravity. However, as the amount of glue remaining in the syringe decreases, the fixed back-suction pressure is prone to cause the back-suction force to exceed the weight of the glue, resulting in glue being sucked back into the adapter or even the controller, causing blockage and damage. At the same time, traditional adapters lack a self-cleaning mechanism, and accumulated glue is prone to solidification, further aggravating blockage and seriously affecting dispensing accuracy and equipment reliability. Therefore, a new type of anti-clogging syringe adapter that can prevent back-suction and is self-cleaning is needed to solve the above pain points. Utility Model Content

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-5 This utility model discloses a novel anti-clogging syringe adapter, comprising an adapter body 1. A slide groove 20 is fixedly installed on the upper end of the adapter body 1, and a slider 19 is slidably connected within the slide groove 20. An adjusting nut 2 is fixedly connected to the upper end of the slider 19. A circular through hole 12 is provided on the upper part of the adapter body 1. One end of the adjusting nut 2 is movably connected to the outside of the circular through hole 12. An adjusting rod 18 is threadedly connected to the lower end of the adjusting nut 2. A second connecting sleeve 15 is movably connected to the outer wall of the adjusting rod 18. The inner wall of the second connecting sleeve 15 is tightly fitted with the outer wall of the adjusting rod 18. The lower end of the adjusting rod 18 is located on a stepped surface 16, which ensures the structural stability of the adjusting nut 2 during rotation adjustment. Furthermore, the tight fit between the second connecting sleeve 15 and the adjusting rod 18 prevents glue from flowing back into the gap. It also provides precise motion guidance and installation support for the anti-backflow function of the stepped surface 16 and the subsequent glue scraping structure, achieving multi-component collaborative optimization.

[0017] Specifically, the upper end of the second connecting sleeve 15 is fixedly connected to the lower end of the adjusting nut 2, and the second connecting sleeve 15 is movably connected inside the circular through hole 12. The second connecting sleeve 15 can rotate synchronously with the adjusting nut 2.

[0018] Specifically, an air tube connector 3 is fixedly installed on the upper end of the adjusting nut 2, and symmetrical clamping blocks 10 are fixedly installed on the lower end of the adapter body 1. The air tube connector 3 ensures stable air pressure transmission, and the symmetrical clamping blocks 10 securely install the syringe. The collaboration of multiple parties improves adaptability and operational reliability.

[0019] Specifically, the stepped surface 16 is externally connected to symmetrical elastic scrapers 17. The symmetrical elastic scrapers 17 are tightly fitted to the stepped surface 16. The upper end of the symmetrical elastic scrapers 17 is fixedly connected to the lower end of the second connecting sleeve 15. The symmetrical elastic scrapers 17 move synchronously with the second connecting sleeve 15 and are tightly fitted to the stepped surface 16. They can scrape off the accumulated adhesive on the stepped surface 16 and its surroundings in real time during the adjustment process, blocking the cause of blockage from the source and ensuring the stable performance of the anti-backflow function of the stepped surface 16.

[0020] Specifically, the lower end of the adjusting rod 18 is set as an air outlet 8, and a circular groove 13 is opened at the upper end of the adjusting rod 18 above the air outlet 8. The air outlet 8 at the lower end of the adjusting rod 18 provides a channel for the flow of gas and glue during the dispensing process, and the circular groove 13 at its upper end can serve as a second line of defense against backflow, which can intercept a small amount of backflow glue that breaks through the step surface 16.

[0021] Specifically, the second connecting sleeve 15 has symmetrical arc-shaped through holes 14, and symmetrical connecting posts 6 are movably connected inside the symmetrical arc-shaped through holes 14. One end of the symmetrical connecting post 6 is fixedly connected to the adjusting rod 18. The arc-shaped through holes 14 do not affect the rotation of the second connecting sleeve 15, nor do they affect the free lifting and lowering of the adjusting rod 18 along the axial direction.

[0022] Specifically, a symmetrical fixing block 4 is fixedly installed at the lower end of the adapter body 1. A symmetrical guide groove 5 is provided on the symmetrical fixing block 4. A symmetrical connecting post 6 is slidably connected inside the symmetrical guide groove 5. The symmetrical fixing block 4 provides structural support. The symmetrical guide groove 5 and the connecting post 6 slide together, which can restrict the rotational freedom of the connecting post 6 and only allow it to slide along the axial direction, so as to ensure the relative scraping movement of the elastic scraper 17 and the step surface 16.

[0023] Specifically, the second connecting sleeve 15 is externally connected to the first connecting sleeve 7. The second connecting sleeve 15 and the first connecting sleeve 7 are tightly fitted together. The upper end of the first connecting sleeve 7 is fixedly connected to the lower end of the adapter body 1. A sealing groove 11 is provided on the outside of the first connecting sleeve 7. A circular sealing ring 9 is fixedly connected in the sealing groove 11. The second connecting sleeve 15 and the first connecting sleeve 7 are tightly fitted together to prevent glue from flowing back into the gap. The circular sealing ring 9 in the sealing groove 11 achieves a reliable seal.

[0024] Working principle: When the adjusting nut 2 is rotated, it slides within the groove 20 of the adapter body 1 via the upper slider 19, simultaneously causing the lower second connecting sleeve 15 to rotate synchronously. The adjusting rod 18, being threadedly connected to the adjusting nut 2 and sliding within the guide groove 5 via the connecting post 6, has its rotational freedom restricted, moving only axially up and down to achieve height adjustment. When the second connecting sleeve 15 rotates, it causes the lower elastic scraper 17 to rotate synchronously. The elastic scraper 17 tightly adheres to the step surface 16 and outer wall of the adjusting rod 18, scraping away the accumulated adhesive and preventing the blockage caused by cured adhesive residue from the source. The cause is that after the dispensing is completed, under the action of the back suction air pressure, the step surface 16 at the lower end of the adjusting rod 18 forms the first physical barrier, preventing the glue from flowing back along the syringe wall; even if a small amount of glue breaks through the step surface 16, the circular groove 13 at its upper end will further intercept and retain the glue, forming the second line of defense; at the same time, the height of the adjusting rod 18 can be adjusted by rotating the adjusting nut 2 to match the remaining glue in the syringe, ensuring that the step surface 16 is always in an effective anti-back suction position, and the circular sealing ring 9 in the sealing groove 11 outside the first connecting sleeve 7 ensures the airtightness of the adapter, preventing glue from being sucked into the adapter and air tube.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
