Technical Field
[0001] This utility model relates to the technical field of bucket lid locking tools, specifically to a round bucket lid fastening locking tool for printing paint buckets. Background Technology
[0002] Printing paint buckets are made of ton-sized plastic drums containing water-based color pastes, which facilitates packaging, transportation, and storage, reducing costs. The lids of the printing paint buckets must be securely locked during transportation or storage.
[0003] Existing bucket lid locking tools generally use round or crescent-shaped plastic single-handle tools. After a period of use, the plastic single handle will wear or deform at the mating part, causing the gap at the mating part to widen, making it inconvenient to apply force. When tightening the plastic single handle and the opposite side, the force will be uneven, making it difficult to lock the bucket lid.
[0004] Therefore, we have made improvements and proposed a round bucket lid fastening locking tool for printing paint buckets. Utility Model Content
[0005] The purpose of this utility model is to address the issue that existing bucket lid locking tools generally use round or crescent-shaped plastic single-handle tools. After a period of use, the plastic single handle will wear or deform at the mating part, causing the gap at the mating part to widen, making it inconvenient to apply force. When tightening the plastic single handle and the opposite side, there will be inconsistency between the upper and lower parts, resulting in uneven force and difficulty in locking the bucket lid.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0010] By fitting the locking ring onto the lid of the printing paint bucket, the abutment block on the lower side of the handle contacts the top surface of the lid, causing the L-shaped frame and T-shaped rod on the upright block to move upward. The upward-moving T-shaped rod causes one of the locking blocks to extend out of the moving groove and abut against the side of the lid. At the same time, the remaining locking blocks extend outward through the groove of the connecting post and the ring block, so that the locking blocks fit tightly against the groove of the lid. By setting the handle to a double-handle shape, parallel and even force can be applied to feel the tightness of the lid locking, thus better securing the lid.

[0034] Example 1
[0035] Please refer to Figure 1-6A locking tool for fastening the lid of a round printing paint bucket includes: a locking ring 1; a handle 2 mounted on the upper side of the locking ring 1; multiple moving grooves 3 arranged in a circular array on the inner circumference of the locking ring 1; locking blocks 4 slidably engaged within each of the multiple moving grooves 3; an abutment block 5 provided on the lower side of the handle 2; a connecting component 6 provided between the abutment block 5 and the multiple locking blocks 4; and an L-shaped groove 7 inside the handle 2 communicating with one of the moving grooves 3. An annular groove 8 inside the locking ring 1 communicating with the multiple moving grooves 3; a first through groove 9 penetrating through the two inner walls of the transverse groove of the L-shaped groove 7; a second through groove 10 penetrating through the top wall of the transverse groove of the L-shaped groove 7; and a connecting groove 11 on the side wall of the transverse groove of the L-shaped groove 7. The connecting assembly 6 includes a vertical block 601 mounted on the top of the abutment block 5 and slidably fitted within the first through groove 9. An L-shaped frame 602, slidably fitted within an L-shaped groove 7, is mounted on the side of the vertical block 601. A T-shaped rod 603, cooperating with one of the locking blocks 4, is mounted on the bottom of the longitudinal side of the L-shaped frame 602. One side of the locking block 4 is a downwardly inclined side 605. A through groove 606, cooperating with the longitudinal rod of the T-shaped rod 603, is opened on the upper side of the locking block 4. The inclined side 605 is in contact with the transverse rod of the T-shaped rod 603. A first spring 607 is installed between the inclined side 605 of one of the locking blocks 4 and the inner wall of the moving groove 3. An annular block 604 is rotatably fitted within the annular groove 8. Multiple grooves 609 are opened on the upper side of the annular block 604. A connecting post 608, cooperating with the grooves 609, is mounted on the bottom of the locking block 4.
[0036] Implementation process: By fitting the locking ring 1 onto the lid of the printing paint bucket, the abutment block 5 on the lower side of the handle 2 contacts the top surface of the lid, causing the upright block 601 to slide upward in the first through groove 9. The upward sliding upright block 601 causes the L-shaped frame 602 to slide upward in the L-shaped groove 7. The horizontal bar of the T-shaped rod 603 at the bottom of the L-shaped frame 602 is in contact with the inclined side 605 of the locking block 4, and the inclined side 605 is set downward, so that the upward moving T-shaped rod 603 causes one of the locking blocks 4 to extend out of the moving groove 3 and abut against the side of the lid. Meanwhile, the remaining locking blocks 4 extend outward through the groove 609 of the annular block 604 via the connecting post 608, so that the locking blocks 4 fit tightly against the groove of the lid. The handle 2 is set as a double handle, which allows for parallel and even force to feel the lid's locking firmness and better fix the lid. The handle 2 can be made of double-handled metal material as a wrench, which extends the service life and reduces costs. The shape can be round, which is easy to fix and facilitates parallel and even force application, saving effort and improving the lid's firmness. The height of the handle 2 is suitable for the height of the printing paint bucket lid.
[0037] Benefits of implementation: The multiple locking blocks 4 inside the locking ring 1 can be tightly fitted into the groove of the bucket lid.

A downwardly inclined beveled block 614 is installed on one side of the slider 611. A plurality of slots 615 that cooperate with the beveled block 614 are opened on one side of the upright block 601.
[0040] Implementation process: When the upright block 601 moves upward, the inclined side locking block 614 cooperates with the locking groove 615 of the upright block 601, and the inclined side of the inclined side locking block 614 is set downward. The force of the second spring 612 keeps the inclined side locking block 614 in the locking groove 615, which plays a fixed limiting role in the position of the upright block 601. By moving the moving rod 613, the inclined side locking block 614 is moved away from the locking groove 615, thereby releasing the fixed limiting of the upright block 601.
[0041] Benefits of implementation: It can fix and limit the position of the stand block 601 on the handle 2.
