A sealing device made of polyurethane resin with good sealing performance

Abstract

This utility model relates to the field of resin sealing technology and discloses a sealing device for polyurethane resin with good sealing performance. The device includes a housing with a storage tank inside. An anti-opening mechanism is provided on the housing. The anti-opening mechanism includes a fixed base, the right side of which is fixed to the left side of the housing. A fixed column is fixedly installed on the fixed base. This sealing device for polyurethane resin with good sealing performance, equipped with an anti-opening mechanism, allows the sealing cover to be closed. When the sealing cover is closed, a blocking block abuts against a rotating rod, causing two sets of rotating rods to rotate outwards, contacting a bottom block that slides outwards. Under the action of the bottom block, the connecting column rotates, and a top block slides inwards to limit the sealing cover. When the sealing cover needs to be opened, the fixed block is twisted, causing the rotating column to drive the fixed rod, connecting rod, and limiting plate to slide outwards, contacting the top block to move outwards, releasing the limitation on the sealing cover. This prevents the sealing cover from loosening due to accidental contact, thus improving the sealing effect and enhancing product quality.

Description

Technical Field

[0001] This utility model relates to the field of resin sealing technology, specifically to a sealing device using polyurethane resin with good sealing performance. Background Technology

[0002] Polyurethane resin is a thermosetting plastic with excellent physical and chemical properties. It features high strength, wear resistance, chemical resistance, and good heat resistance. Polyurethane resin can be used to manufacture foams, coatings, adhesives, and elastic materials.

[0003] Some liquid resins need to be sealed and stored when not in use. However, most sealing devices are one-piece units, and after prolonged use, the internal sealing cavity becomes difficult to clean. This causes the resin poured into the sealing cavity to become cloudy due to the dirty cavity, resulting in resin contamination. Although some use storage tanks placed separately in the sealing cavity, the sealing cap may loosen if not properly closed, affecting the sealing effect and product quality. The gap between the storage tank and the sealing cavity is also narrow, making it difficult to remove and affecting work efficiency. Utility Model Content

[0021] like Figures 1-6 As shown, this utility model provides a technical solution: a sealing device for polyurethane resin with good sealing performance, including a shell 1, a storage tank 11 inside the shell 1, and an anti-opening mechanism 6 on the shell 1. The anti-opening mechanism 6 includes: a fixed base 601, a fixed column 602, a connecting column 603, a bottom block 604, a top block 605, a sliding rod 606, a sliding groove 607, a spring 608, a limiting plate 609, a connecting rod 610, a fixed rod 611, a rotating column 612, and a fixing block 613.

[0022] The right side of the fixed base 601 is fixed to the left side of the outer shell 1. A fixed post 602 is fixedly installed on the fixed base 601. A connecting post 603 is rotatably connected to the fixed post 602. The bottom of the connecting post 603 is hinged to the bottom block 604. The bottom block 604 is slidably connected to the fixed base 601. A sliding rod 606 is fixedly installed on the top of the connecting post 603. The sliding rod 606 is slidably connected to the top block 605. When the blocking block 5 presses the rotating rod 705 to rotate outward, the rotating rod 705 abuts against the bottom block 604 and slides outward, driving the connecting post 603 to rotate. The top block 605 moves outward to limit the sealing cover 2. Sliding grooves 607 are opened on both sides of the top block 605. The sliding rod 606 is slidably connected to the sliding grooves 607. The left end of the top block 605 is fixed to one end of the spring 608. The other end of 08 is fixed to the fixed seat 601. After the limit is released, the spring 608 rebounds and touches the top block 605 to reset. The limiting plate 609 is slidably connected to the top of the sealing cover 2. A connecting rod 610 is fixedly installed on the side of the limiting plate 609 away from the fixed seat 601. The connecting rod 610 is slidably connected to the sealing cover 2. The end of the connecting rod 610 away from the limiting plate 609 is hinged to the fixed rod 611. The fixed rod 611 is fixed to the rotating column 612. The rotating column 612 is rotatably connected to the top of the sealing cover 2. A fixing block 613 is fixedly installed on the top of the rotating column 612. When the fixing block 613 is twisted, the rotating column 612 and the fixing rod 611 rotate. The connecting rod 610 and the limiting plate 609 slide outward and touch the top block 605 to move outward, so that it releases the limit on the sealing cover 2.

[0023] A limiting mechanism 7 is provided on the outer casing 1. The limiting mechanism 7 includes a limiting block 701, which is slidably connected to the outer casing 1. One end of the limiting block 701 penetrates the inner wall of the outer casing 1, and a second spring 702 is fixedly installed on the other end of the limiting block 701. The end of the second spring 702 away from the limiting block 701 is fixed to the outer casing 1. When the sliding plate 8 is pressed downward, the sliding plate 8 abuts against the limiting block 701, and the limiting block 701 slides outward. When the sliding plate 8 is released from the limiting position, the second spring 702 rebounds, causing the limiting block 701 to reset. A sliding post 703 is fixedly installed on the top of the limiting block 701. The sliding post 703 is slidably connected to the outer casing 1, and the side of the sliding post 703 away from the second spring 702 is fixed. A spring 704 is installed, with one end of the spring 704 away from the sliding column 703 fixed to the outer shell 1. When the blocking block 5 presses the rotating rod 705, the sliding column 703 slides inward, pressing the spring 704. The sliding column 703 drives the limiting block 701 to slide inward, stretching the spring 702. When the limiting is released, the spring 704 rebounds and resists the sliding column 703 to slide outward. The spring 702 pulls back and drives the limiting block 701 to slide outward. The top of the sliding column 703 is rotatably connected to a sliding column 706, and the sliding column 706 is rotatably connected to a rotating rod 705. The sliding column 706 is slidably connected to the outer shell 1. A spring is provided at the hinge between the rotating rod 705 and the sliding column 703.

[0024] The top of the outer shell 1 is hinged to the sealing cover 2. A handle 3 is fixedly installed on the sealing cover 2. A sealing ring 4 is fixedly installed on the bottom of the sealing cover 2. A blocking block 5 is fixedly installed on the bottom of the sealing cover 2. The bottom inner wall of the outer shell 1 is fixed to one end of the connecting spring 9. The other end of the connecting spring 9 is fixed to the bottom of the sliding plate 8. The sliding plate 8 is slidably connected to the outer shell 1. A fixing ring 10 is fixedly installed on the top of the sliding plate 8. A storage tank 11 is provided inside the fixing ring 10. A handle 12 is fixedly installed on the storage tank 11. There are two sets of fixing seats 601, which are distributed on both sides of the outer shell 1. The limiting plate 609 is horizontally aligned with the top block 605. There are two sets of rotating rods 705. The bottom block 604 is located on both sides of the rotating rod 705.

[0025] Working principle: When this utility model is in operation, the resin to be stored is placed into the storage tank 11, and then the storage tank 11 is placed into the fixing ring 10. When the handle 12 is held and pressed, the sliding plate 8 descends, and the sliding plate 8 presses against the limiting block 701, causing it to slide outward. When the sliding plate 8 is released from the limit, the second spring 702 rebounds, causing the limiting block 701 to reset and limit the sliding plate 8. Then, the handle 3 is held to close the sealing cover 2, and the blocking block 5 abuts against the rotating rod 705, causing it to rotate outward. When the rotating rod 705 abuts against the outer shell 1, it causes the sliding column 706 and the sliding column 703 to slide inward. The sliding column 703 squeezes the third spring 704, and the sliding column 703 causes the limiting block 701 to move inward, stretching the second spring 702. When the rotating rod 705 rotates, it abuts against the bottom block 604. When the bottom block 604 moves outward, it causes the connecting column 603 to rotate. Under the action of the fixed seat 601, the top block 605 slides inward to limit the sealing cover 2, and the sealing ring 4 is in contact with the inner wall of the outer shell 1. When the resin is to be removed, the fixed block 613 is twisted, the rotating column 612 and the fixed rod 611 rotate, the connecting rod 610 and the limiting plate 609 slide horizontally outward, and the limiting plate 609 abuts against the top block 605. Under the action of the sliding groove 607 and the sliding rod 606, the top block 605 slides outward to release the limitation on the sealing cover 2. After the sealing cover 2 is opened, the limitation is released. The first spring 608 drives the top block 605 to reset. The rotating plate is reset under the action of the spring piece. The third spring 704 rebounds and drives the sliding column 703 and the sliding column 706 to slide horizontally outward. Under the action of the sliding column 703 and the second spring 702, the limiting block 701 slides outward to release the limitation on the sliding plate 8. The connecting spring 9 rebounds and drives the sliding plate 8 to rise, and the storage tank 11 is removed.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
