Technical Field

[0001] This utility model relates to the field of plastic handle technology, and more specifically, to a plastic handle for cardboard boxes that is easy to assemble and disassemble. Background Technology

[0002] Plastic handles for cardboard boxes are accessories made of plastic, primarily used for handling and carrying cardboard boxes. They are typically made from synthetic resins through addition or condensation polymerization, and are lightweight, durable, and rust-resistant. Their ergonomic design makes them easy to grip, allowing people to lift cardboard boxes more easily. Widely used in various cardboard packaging for beverages, milk, and other products, they not only facilitate the transportation and sale of goods but also bring convenience to consumers.

[0003] Publication No. (CN212126054U) discloses an external plastic handle for packaging cartons, including a plastic handle, a connecting part, and a limiting block. The connecting part is fixedly installed on both sides of the plastic handle. The beneficial effects achieved by this utility model are: the utility model has a compact structure, is easy to use, and has practical functions. The bottom of the handle body is equipped with an arc-shaped groove, which allows the gripping fingers to be fixed in the arc-shaped groove, enhancing the gripping ability. The anti-slip texture on the arc-shaped groove can further increase the friction between the fingers and the handle body, effectively preventing slippage. The multiple arc-shaped grooves can adapt to gripping from various directions, enhancing the comfort of gripping the handle body. The bendable structure of the snap-fit ​​block allows the assembler to simply bend the snap-fit ​​block and install it on the packaging box, which is convenient and quick, saving the process of installing and fixing the base plate, effectively improving the work efficiency of the assembler and saving labor.

[0004] However, this type of external plastic handle for packaging cartons has the following drawbacks: it cannot achieve quick disassembly of the plastic handle while satisfying the comfort of the hand; it is still connected by the traditional bending method, which has limited connection strength. In daily use, especially when the cartons are loaded with heavy items, the bends of the handles are prone to damage due to insufficient tension, causing the handles to break and items to fall during handling, causing inconvenience to consumers and even potentially damaging the items. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a plastic handle for cardboard boxes that is easy to assemble and disassemble, so as to solve the problem that the prior art cannot achieve quick disassembly of the plastic handle while satisfying the comfort of the palm.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a plastic handle for cardboard boxes that is easy to assemble and disassemble, comprising...

[0007] The connecting strap has a storage groove on its outer side and a connecting hole on its inner wall. A limiting plate is movably connected to the outer side of the connecting strap. A connecting post is fixedly connected to the inner side of the limiting plate. A locking tooth is fixedly connected to the outer side of the limiting plate. A movable groove is formed on the inner wall of the limiting plate. A fixing plate is movably connected to the outer side of the limiting plate. A locking tooth is fixedly connected to the outer side of the fixing plate. A limiting groove is formed on the inner wall of the fixing plate. A fixing component for fixing subsequent parts is movably connected to the outer side of the connecting strap.

[0008] The fixing component includes an anti-slip sleeve, the inner wall of which is movably connected to the outside of the connecting belt, a vent hole is provided inside the anti-slip sleeve, a rubber pad is fixedly connected to the inner wall of the anti-slip sleeve, a locking post is fixedly connected inside the anti-slip sleeve, and a cavity is provided inside the anti-slip sleeve.

[0009] The end of the rubber pad away from the anti-slip sleeve is in contact with the outside of the connecting band, and the outside of the connecting band is movably connected to the inner wall of the cavity.

[0010] The end of the connecting post away from the limiting plate is movably connected to the inner wall of the connecting hole, and the end of the first locking tooth away from the limiting plate is in contact with the outside of the second locking tooth.

[0011] The end of the second locking tooth away from the fixed plate is in contact with the outside of the limiting plate, and the outside of the connecting strip is movably connected to the inner wall of the movable groove.

[0012] The connecting strip is externally movably connected to the inner wall of the limiting groove, and the outer side of the limiting plate is in contact with the outer side of the fixing plate.

[0013] The outer side of the first locking tooth contacts the inner wall of the storage groove, and the outer side of the limiting plate contacts the inner wall of the storage groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, by pulling the connecting belt, the first locking tooth in the limiting plate is engaged with the second locking tooth in the fixing plate. The engagement of the first and second locking teeth is a staggered engagement. When the connecting belt is pulled, the first and second locking teeth interlock and engage the post. When the connecting belt is released, the first and second locking teeth no longer engage. At the same time, during disassembly, by rotating the limiting plate, the limiting plate uses the connecting post as a fulcrum, causing the connecting post to rotate inside the connecting hole. Half of the limiting plate is then stored inside the storage groove in the connecting belt. In this way, the limiting plate and the connecting belt merge and easily pass through the limiting groove in the fixing plate, achieving quick disassembly.

[0016] In the above solution, by setting a fixing component, when the connecting belt is to be pulled, the anti-slip sleeve is held and the connecting belt is lifted. The rubber pad in the anti-slip sleeve will squeeze the connecting belt. Due to the characteristics of the rubber pad, the friction will be increased. When the connecting belt is lifted, the carton will not shift or shake. In addition, the anti-slip sleeve has ventilation holes, which allows ventilation to the palm of the hand when the carton is lifted by holding the anti-slip sleeve, preventing the palm from sweating. At the same time, by prying open the anti-slip sleeve, the locking post will disengage from the inside of the anti-slip sleeve and will no longer be locked. This realizes the modular design of the anti-slip sleeve, which can be disassembled and reused repeatedly. Attached Figure Description

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] As attached Figure 1 To be continued Figure 6 An embodiment of this utility model provides a plastic handle for cardboard boxes that is easy to assemble and disassemble, including...

[0027] The connecting strap 1 is the main load-bearing component of the entire plastic handle, used for lifting cartons, and is the basic structure for realizing the handle's function. The connecting strap 1 has a storage groove 2 on its exterior. The storage groove 2 provides space for the storage of the limiting plate 5 when the handle is disassembled, making disassembly and removal easier and faster. The connecting strap 1 has a connecting hole 3 on its inner wall. The connecting hole 3 is used to cooperate with the connecting post 4, allowing the limiting plate 5 to be movably connected to the connecting strap 1, thus enabling the limiting plate 5 to rotate. The limiting plate 5 is movably connected to the exterior of the connecting strap 1. The limiting plate 5 plays an important role in limiting and connecting in the handle's structure. It cooperates with the fixing plate 8 to fix and disassemble the handle. The connecting post 4 is fixedly connected inside the limiting plate 5. One end of the connecting post 4 is fixed inside the limiting plate 5, and the other end is inserted into the connecting hole 3 of the connecting strap 1, providing a fulcrum for the rotation of the limiting plate 5. The limiting plate 5 is externally fixedly connected to a locking tooth 6. Locking tooth 6 engages with locking tooth 9 during handle operation, securing the connecting strap 1 and preventing it from sliding freely. The inner wall of the limiting plate 5 has a movable groove 7, allowing the connecting strap 1 to move within it, ensuring its flexibility within the handle structure. The limiting plate 5 is externally movably connected to a fixing plate 8, a crucial component in the handle structure, which works with the limiting plate 5 to enable the installation and removal of the handle. The fixing plate 8 is externally fixedly connected to a locking tooth 9, which engages with locking tooth 6. When the connecting strap 1 is pulled, it is secured by a staggered engagement; when the connecting strap 1 is released, locking tooth 6 separates from locking tooth 9, facilitating handle operation. A limiting groove 10 is formed on the inner wall of the fixing plate 8. The limiting groove 10 is used to limit the connecting strap 1. At the same time, during disassembly, the connecting strap 1 and the combined limiting plate 5 can pass through the limiting groove 10 to realize the disassembly of the handle. The connecting strap 1 is externally connected to the fixing assembly.

[0028] The fixing component includes an anti-slip sleeve 11, which is fitted over the connecting strap 1. When lifting the carton, the user grips the anti-slip sleeve 11, increasing grip comfort and stability and preventing marks on the user's hands. The inner wall of the anti-slip sleeve 11 is movably connected to the outside of the connecting strap 1, allowing the anti-slip sleeve 11 to move relative to the connecting strap 1 for easy adjustment in different situations. Ventilation holes 12 are provided inside the anti-slip sleeve 11, allowing ventilation for the palms when lifting the carton, preventing sweating from prolonged gripping and affecting grip stability. A rubber pad 13 is fixedly connected to the inner wall of the anti-slip sleeve 11. When the user grips the anti-slip sleeve 11 and lifts the connecting strap 1, the rubber pad 13 compresses the connecting strap 1, increasing friction and preventing the carton from shifting or shaking when lifting the connecting strap 1. The anti-slip sleeve 11 is internally fixedly connected with a locking post 14, which is used to fix the anti-slip sleeve 11 to the connecting strap 1, ensuring that the anti-slip sleeve 11 will not easily fall off the connecting strap 1 during normal use. The anti-slip sleeve 11 has a cavity 15 inside, which provides space for the connecting strap 1 to move inside the anti-slip sleeve 11, allowing the connecting strap 1 to move normally within the cavity 15.

[0029] The end of the rubber pad 13 furthest from the anti-slip sleeve 11 is in contact with the outside of the connecting strap 1, so that the rubber pad 13 can directly apply pressure to the connecting strap 1, increasing friction and ensuring stability when lifting the carton. The outside of the connecting strap 1 is movably connected to the inner wall of the cavity 15, allowing the connecting strap 1 to move flexibly inside the anti-slip sleeve 11 without affecting the normal use of the handle.

[0030] The end of the connecting post 4 furthest from the limiting plate 5 is movably connected to the inner wall of the connecting hole 3. This allows the limiting plate 5 to rotate on the connecting belt 1 with the connecting post 4 as a fulcrum, achieving a movable connection between the limiting plate 5 and the connecting belt 1. The end of the first locking tooth 6 furthest from the limiting plate 5 is in contact with the outside of the second locking tooth 9. When the connecting belt 1 is pulled up, the first locking tooth 6 and the second locking tooth 9 interlock with each other through a staggered engagement, fixing the connecting belt 1 and ensuring the stability of the handle during the lifting process.

[0031] The end of the second locking tooth 9 furthest from the fixed plate 8 contacts the outside of the limiting plate 5. When the connecting belt 1 is pulled up, the second locking tooth 9 engages with the first locking tooth 6 while simultaneously contacting the outside of the limiting plate 5, further enhancing the stability of the connecting belt 1. The external movable connection of the connecting belt 1 is attached to the inner wall of the movable groove 7, allowing the connecting belt 1 to move flexibly within the limiting plate 5 without affecting the normal operation of the handle.

[0032] The connecting strap 1 is externally and movably connected to the inner wall of the limiting groove 10. The limiting groove 10 limits the connecting strap 1, and when disassembling the handle, the connecting strap 1 and the combined limiting plate 5 can pass through the limiting groove 10 for quick disassembly. The outer side of the limiting plate 5 is in contact with the outer side of the fixing plate 8. After the handle is installed, the limiting plate 5 and the fixing plate 8 are in contact with each other, ensuring the compactness and stability of the handle structure.

[0033] The outer side of the locking tooth 6 contacts the inner wall of the storage groove 2. When the limiting plate 5 is inserted into the storage groove 2 of the connecting strap 1, the locking tooth 6 can also be inserted into the storage groove 2, allowing the limiting plate 5 and the connecting strap 1 to merge better. The outer side of the limiting plate 5 contacts the inner wall of the storage groove 2. When disassembling the handle, half of the limiting plate 5 is inserted into the storage groove 2 and contacts the inner wall of the storage groove 2, making it easy to pass through the limiting groove 10 of the fixing plate 8 for quick disassembly.

[0034] The working process of this utility model is as follows:

[0035] First, by pulling the connecting strap 1, the first tooth 6 in the limiting plate 5 is engaged with the second tooth 9 in the fixing plate 8. The engagement of the first tooth 6 and the second tooth 9 is a misaligned engagement. When the connecting strap 1 is pulled, the first tooth 6 and the second tooth 9 are interlocked and locked together. When the connecting strap 1 is released, the first tooth 6 and the second tooth 9 are no longer engaged. At the same time, during disassembly, by rotating the limiting plate 5, the limiting plate 5 is rotated around the connecting post 4 as a fulcrum, causing the connecting post 4 to rotate inside the connecting hole 3. Half of the limiting plate 5 is then stored inside the storage groove 2 in the connecting strap 1. In this way, the limiting plate 5 and the connecting strap 1 are merged, and the limiting plate 5 easily passes through the limiting groove 10 in the fixing plate 8, achieving quick disassembly.

[0036] When the connecting strap 1 is pulled, the anti-slip sleeve 11 is held and the connecting strap 1 is pulled. The rubber pad 13 in the anti-slip sleeve 11 will squeeze the connecting strap 1. Due to the characteristics of the rubber pad 13, the friction will be increased. When the connecting strap 1 is pulled, the carton will not shift or shake. The anti-slip sleeve 11 has ventilation holes 12, which allows ventilation to the palm of the hand when the carton is pulled by holding the anti-slip sleeve 11, preventing the palm from sweating. At the same time, by prying open the anti-slip sleeve 11, the locking post 14 will disengage from the inside of the anti-slip sleeve 11 and will no longer be locked. This realizes the modular design of the anti-slip sleeve 11, which can be disassembled and reused repeatedly.
