Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical delivery pipe technology, specifically a connection device for pharmaceutical delivery pipelines. Background Technology

[0002] Wastewater treatment requires the addition of chemical agents to improve water quality through aeration and mixing. Since these chemical agents may be highly corrosive, toxic, or easily cause environmental pollution, specialized chemical agent delivery pipeline structures are required.

[0003] The prior art patent document CN207687521U provides a connecting device for a chemical agent delivery pipeline, including two sleeves and two cover plates. The opening of the sleeve can be fitted onto the outer tube of the delivery pipeline to form a connection. The limiting tube is inserted into the sleeve through the window and the two semi-circular tubes fit around the inner tube of the delivery pipeline. At the same time, the connecting piece abuts against the inner wall of the sleeve and engages with the positioning groove, thereby stabilizing the relative position of the sleeve and the limiting tube. Through the combination of the above structures, the inner tube of the delivery pipeline can completely avoid contact with the outer tube of the delivery pipeline and is isolated and protected by the outer tube of the delivery pipeline. This prevents the inner tube of the delivery pipeline from rubbing against the outer tube of the delivery pipeline during the vibration and expansion and contraction of the fluid during delivery, thereby effectively improving its durability.

[0004] Although the device has many beneficial effects, it still has the following problems: During the use of the device, the two sleeves are spliced ​​together by an adhesive layer, which is not stable enough and affects the delivery of the medicine; secondly, the diameter of the delivery pipe is fixed during the use of the device, which is not convenient to adapt to the interface of medicine tanks of different sizes and needs to be improved. In view of this, we propose a connection device for medicine delivery pipeline. Utility Model Content

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a connection device for a pharmaceutical delivery pipeline, including:

[0035] Please see Figures 1-5This embodiment provides a connecting device for a pharmaceutical delivery pipeline, comprising a delivery pipe 1. A fixing ring 2 is welded to one end of the outer circumference of the delivery pipe 1. Two fixing sleeves 3 are engaged with the outer circumference of the fixing ring 2. Connecting blocks 4 are welded to both ends of the outer circumference of the two fixing sleeves 3. A snap-fit ​​assembly 5 is fixedly provided on the top of the connecting block 4. The snap-fit ​​assembly 5 includes a snap block 501. Another snap block 501 has a snap groove 502 at its bottom. A rotating shaft 503 is rotatably connected to the bottom of the snap block 501. A gear 504 is fixedly provided on the top of the rotating shaft 503. Gear plates 505 mesh with both ends of the outer circumference of the gear 504. Limiting plates 506 are fixedly provided on the side walls of both gear plates 505. Springs 507 are fixed to one end of each plate 506. Limiting grooves 508 are opened on both sides of the slot 502. The other end of the conveying pipe 1 is welded with an installation component 6. The two conveying pipes 1 are spliced ​​together. By rotating the shaft 503, the gear 504 is driven to rotate, thereby causing the two toothed plates 505 to drive the two limiting plates 506 to move inward at the same time. The two fixing sleeves 3 are fitted on the outer circumference of the fixing ring 2, so that the locking block 501 enters the slot 502 of another connecting block 4. The rebound force of the spring 507 drives the two limiting plates 506 to move outward at the same time and enter the limiting groove 508, which improves the splicing stability of the two conveying pipes 1 and facilitates the delivery of medicine.

[0036] It is worth noting that, in order to facilitate centralized collection of sugarcane, the installation component 6 specifically includes a threaded pipe 601, with a plug 602 welded to one end. A threaded sleeve 603 is threadedly connected to the outer circumference of the threaded pipe 601, and an installation disc 604 is welded to the outer circumference of the threaded sleeve 603. The side wall of the installation disc 604 has multiple installation holes 605. By inserting the plug 602 into the interface of the chemical tank, rotating the threaded sleeve 603 drives the installation disc 604 to move along the threaded pipe 601. After the installation disc 604 abuts against the chemical tank, it is fixed in place through the installation holes 605, thereby allowing the conveying pipe 1 to be installed in the required position, which is convenient for adapting to interfaces of different sizes.

[0037] Next, in order to make the splicing of the two fixed sleeves 3 more stable, specifically, the size and position of the card block 501 are matched with the size and position of the card slot 502, and the size and position of the limiting plate 506 are matched with the size and position of the limiting groove 508. By using the limiting plate 506 which matches the size and position of the limiting groove 508, the stability of the splicing of the two connecting blocks 4 is improved.

[0038] Meanwhile, to facilitate the rotation of the shaft 503 by the staff, a handle 509 is fixedly provided at one end of the shaft 503 that passes through the connecting block 4. Multiple striped protrusions are fixedly provided on the outer circumference of the handle 509. The striped protrusions help to increase the friction of the handle 509 and make it easier for the staff to use.

[0039] Furthermore, to facilitate the delivery of the medicine, specifically, the plug 602 is tapered, and the inner diameter of the threaded tube 601 matches the inner diameter of the delivery tube 1. The delivery of the medicine is facilitated by the threaded tube 601 that matches the inner diameter of the delivery tube 1.

[0040] It is worth noting that, in order to prevent the drug from seeping out, specifically, the side wall of the fixing ring 2 is provided with an annular groove 7, and the inner circumference of the annular groove 7 is fixed with a first sealing ring 8. The sealing performance is improved by the two first sealing rings 8 abutting each other, thus preventing the drug from leaking.

[0041] Finally, in order to improve the performance of the sealing ring, specifically, a second sealing ring 9 is fixed on the inner wall of the circumference of the fixed sleeve 3. The material of the first sealing ring 8 and the second sealing ring 9 is HNBR. HNBR is hydrogenated nitrile rubber, which has excellent corrosion resistance, tear resistance and compression deformation resistance. It also has good ozone resistance, sunlight resistance and weather resistance. The general operating temperature range is -40 to 150℃.

[0042] Combination Figures 1-5 The specific usage process of the connection device for a drug delivery pipeline according to this embodiment is as follows:

[0043] 1: When this device is needed to connect the drug delivery pipeline, the two delivery pipes 1 are spliced ​​together. Turning the handle 509 drives the rotating shaft 503 to rotate, thereby causing the gear 504 to rotate and drive the two toothed plates 505 to move inward at the same time. The two fixing sleeves 3 are placed on the outer wall of the circumference of the fixing ring 2, so that the locking block 501 enters the locking groove 502 of the other connecting block 4. When the handle 509 is released, the rebound force of the spring 507 drives the two limiting plates 506 to move outward at the same time and enter the limiting groove 508.

[0044] 2: Insert the plug 602 into the medicine tank interface, rotate the threaded sleeve 603 to move the threaded sleeve 603 along the direction of the threaded tube 601, so that the mounting plate 604 abuts against the medicine tank, screw the thread into the mounting hole 605 to fix the mounting plate 604, so that the delivery tube 1 is installed in the required position.

[0045] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
