[0002] In order to facilitate carrying and transporting, slightly larger packaging cartons are generally equipped with a handle structure. There are two types of commonly used handle knots: one is to directly die-cut a handle hole on the packaging carton, and the handle hole is the handle structure; the other is to connect a set of lifting handles to the packaging carton as the handle structure, and the handles are generally made of plastic belts; the handle holes are generally set on the side, which is not convenient for users to lift with one hand, so the lifting handles are mostly used as the handle structure;

[0003] The lifting handle currently used as a handle structure is not convenient to roll up, and the handle is directly exposed to the outside of the carton, which makes the handle easily hooked by external objects, thereby causing the box to be damaged by the hook, which is inconvenient to use. In addition, the length of the handle cannot be adjusted, which also reduces the applicability of the handle and limits the way of carrying. It is less practical and inconvenient to use.

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0023] like Figures 1 to 5 A packaging carton handle structure shown in the figure includes a fixed frame 1, a buckling plate 2 and a carrying rope 13, the fixed frame 1 is connected with an insertion rod 3, the insertion rod 3 is provided with several groups, the buckling plate 2 is detachably connected to the insertion rod 3, and the connection between the device and the carton is completed by the insertion rod 3, the fixed frame 1 and the buckling plate 2; the fixed frame 1 is slidably connected with a storage roller 7, the fixed frame 1 is connected with a reset spring 6, the free end of the reset spring 6 is rotatably connected with the storage roller 7, the storage roller 7 is provided with two groups, the two ends of the carrying rope 13 are respectively connected with the two groups of storage rollers 7, the fixed frame 1 is provided with a through hole 14, the end of the carrying rope 13 passes through the through hole 14 and is connected to the storage roller 7, the storage roller 7 is connected with a limiting rod 11, and the left side wall of the fixed frame 1 is provided with a limiting hole 10, the limiting rod 11 can be inserted into the limiting hole 10, thereby limiting the rotation of the storage roller 7.

[0024] The fixed frame 1 is connected to the limiting cylinder 5, the right end of the storage roller 7 is slidably connected to the limiting cylinder 5, the reset spring 6 is located on the inner side of the limiting cylinder 5, the load-bearing rope 13 is connected to the anti-sweat thickened pad 15, and there are four groups of limiting holes 10. The four groups of limiting holes 10 are arranged in a ring shape with the axis of the storage roller 7 as the center. The buckling plate 2 is provided with a slot 4, and the insertion rod 3 is slidably connected to the slot 4. The buckling plate 2 and the insertion rod 3 can be quickly buckled through the slot 4. The buckling plate 2 and the insertion rod 3 are connected by bolts. A storage groove 16 is provided on the top of the fixed frame 1, and the storage groove 16 can accommodate the anti-sweat thickened pad 15.

[0025] The left end of the storage roller 7 passes through the fixed frame 1 and is rotatably connected to the pull plate 9. The two groups of storage rollers 7 are rotatably connected to the pull plate 9. The two groups of storage rollers 7 are respectively connected to the transmission wheels 8, and the transmission wheels 8 are connected to the transmission belt 12. The cooperation of the transmission belt 12 and the transmission wheel 8 enables the two groups of storage rollers 7 to rotate simultaneously. The transmission belt 12 and the transmission wheel 8 are the transmission belt 12 assembly. The structure and transmission principle of the transmission belt 12 assembly are the existing technology well known to practitioners in this field and will not be repeated here.

[0026] The specific implementation process is as follows:

[0027] During installation, a hole is first punched in the side wall of the carton, and then the insertion rod 3 is moved through the hole, and then the buckle plate 2 is buckled, and the buckle plate 2 is connected to the insertion plate by bolts. After the connection is completed, the fixed frame 1 and the buckle plate 2 are respectively in contact with the outer wall and the inner wall of the carton. The following is a further description of the rotation of the storage roller 7 to retract the load rope 13. Figure 1As shown, at this time, the limit has just been inserted into the limit hole 10, and the storage roller 7 cannot be easily moved to the left under the elastic force of the return spring 6, so that the storage roller 7 cannot be easily rotated at this time. When it is necessary to rotate, the pull plate 9 is pulled to the left, and the pull plate 9 drives the two groups of storage rollers 7 to move to the left at the same time, so that the limit rod 11 slides out of the limit hole 10 and the spring is stretched at the same time, and the storage roller 7 can be rotated to complete the winding or releasing of the load-bearing rise. Due to the setting of the transmission wheel 8 and the transmission belt 12, only one group of storage rollers 7 needs to be rotated to make the two groups of storage rollers 7 rotate at the same time. After the adjustment is completed, the limit rod 11 is aligned with the corresponding limit hole 10, and the pull plate 9 is released. Under the action of the restoring force of the return spring 6, the storage roller 7 and the pull plate 9 can be pulled to move to the left, and then the limit rod 11 is inserted into the corresponding limit hole 10 again to complete the rotation limit of the storage roller 7; When the carrying rope 13 is not in use, it can be rolled up by rotating the storage roller 7. After the rolling is completed, the sweat-proof thickened pad 15 is stored in the receiving groove and can be released when needed. In actual use, handle structures can be set on both sides of the carton. When the object in the carton is heavy and needs two people to lift it, it is only necessary to release the carrying rope 13 for a short distance. When it is lifted by one person, the carrying rope 13 can be released for a longer distance, so that one person can hold the carrying ropes 13 on both sides at the same time to complete the lifting with one hand; the carrying rope 13 of the corresponding length can also be released according to the actual carrying situation so that the staff can lift it with a shoulder pole or use the carrying rope 13 as a shoulder strap to carry it on their back, etc., which greatly improves the practicality and use effect of the handle structure; the handle structure can be removed later to facilitate its multiple use.

[0028] When the present technical solution is in use, the handle devices can be respectively arranged on both sides of the carton, and the storage rollers 7 are arranged to retract and release the carrying ropes 13. When not in use, the carrying ropes 13 can be closely attached to the fixed frame 1 to avoid being hooked by the outside world and improve the stability in use; at the same time, the release length of the carrying ropes 13 can be adjusted by rotating the storage rollers 7, thereby improving the practicality of the handle structure, so that the length of the carrying ropes 13 can be appropriately adjusted according to different lifting methods, thereby greatly improving the applicability and practicality of the handle structure, and the rotation limit of the storage rollers 7 can be restricted or released by pulling the storage rollers 7, the structure is simple and easy to use; the force transmission stability of the storage rollers 7 is improved by the limiting cylinder 5, and the lifting The load-bearing capacity of the high handle structure is increased; the contact area between the load-bearing rope 13 and the palm of the user is increased by the anti-sweat thickened pad 15, thereby improving the comfort of use; the two sets of storage rollers 7 can rotate simultaneously through the transmission wheel 8 and the transmission belt, so that the load-bearing rope 13 can be released and stored at the same time, which is convenient for the winding operation; multiple sets of limit holes 10 are provided to improve the adjustment accuracy of the release length of the load-bearing rope 13; the connection between the snap-fit ​​plate 2 and the fixed frame 1 is completed by bolts, which is convenient for installing the device on the carton, so that the carton and the handle structure can be produced separately, thereby improving production efficiency; the storage of the anti-sweat thickened pad 15 can be completed through the storage groove 16, further preventing foreign objects from hooking the load-bearing rope 13.
