Description

Technical Field

[0001] The utility model relates to the technical field of cartons, in particular to a carton which is easy to seal. Background Art

[0002] Cartons are commonly used packaging in production and life, and can be used to store things. There are many types of cartons on the market, including corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. They are environmentally friendly, lightweight, have good moisture-proof and impact-resistant capabilities, and are easy to make. They are widely used in food, medicine, transportation, instrumentation and other industries. The carton needs to be sealed after storing the items, especially during transportation, to prevent leakage of items.

[0003] For example, a Chinese patent (publication number: CN213293228U) discloses a carton that is easy to seal. The technical highlights are: it includes a bottom plate, a side plate, a first sub-cover plate and a second sub-cover plate arranged at the opening of the carton, and a first main cover plate and a second main cover plate arranged on the first sub-cover plate and the second sub-cover plate. The first main cover plate is provided with a sealing strip extending in the direction of the second main cover plate, which has the advantage of easy sealing.

[0004] The above technical solution also has the following defects. Although the easy-to-seal carton has the advantage of being easy to seal, in the actual process of storing and transporting items, the boxes are usually stacked up to save space. When the sealed cartons are stacked up, they are easily dislocated and moved under the action of external force, which makes it easier for the boxes to slide and fall, and even cause damage to the boxes. Based on this, a carton that is easy to seal is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 In this embodiment, a carton that is easy to seal includes a sealed carton 1, a connecting plate 2 is fixed to the lower surface of the sealed carton 1, and a fixing mechanism 3 is provided on the sealed carton 1 and the connecting plate 2.

[0024] It should be noted that by adjusting the operating connecting plate 2, the two sealed cartons 1 can be stably stacked, so that the stacked sealed cartons can be further prevented from moving or overturning due to external forces during transportation or storage, and the cartons and the items inside are further protected from damage.

[0025] See also Figure 1-3In order to facilitate the stable stacking of sealed cartons during transportation or storage, the fixing mechanism 3 in this embodiment includes a driving component, on which an adjustment component is provided. The fixing mechanism 3 also includes a limiting component. The driving component includes a worm 301, one end of which is rotatably connected to the right side of the connecting plate 2 through a bearing and the other end of which passes through the outside of the connecting plate 2. A through hole is opened on the left side of the connecting plate 2, and a sealing ring is fixed on the inner wall of the through hole. The inner wall of the sealing ring is fitted with the outer side of the worm 301. A handle 302 is fixed to the left end of the worm 301. A worm wheel 303 is meshed in the middle of the outer surface of the worm 301. A rotating rod 304 is fixed on the inner wall of the axis of the worm wheel 303, which is rotatably connected to the front and rear sides of the inner cavity of the connecting plate 2 through a bearing. By rotating the worm 301, the worm wheel 303 and the rotating rod 304 can be driven to rotate, thereby facilitating the operation of the subsequent adjustment component.

[0026] The adjusting assembly includes a gear 305 fixed to the front and rear sides of the outer surface of the rotating rod 304, and the upper and lower sides of the outer surface of the gear 305 are meshed with tooth plates 307. The adjusting assembly also includes two sets of guide rods 306 fixed between the left and right sides of the inner cavity of the connecting plate 2. The guide rods 306 are slidably connected to the tooth plates 307, and the moving block 308 is slidably connected between the outer surfaces of the four guide rods 306, so that the tooth plates 307 can more stably drive the moving block 308 to move when they are forced to move. A moving block 308 is fixed on the opposite side of the two sets of tooth plates 307. A T-shaped slider 310 is fixed on the top of the moving block 308 to provide support for the movement of the moving block 308, so that the movement of the moving block 308 is more stable. Two T-shaped slide grooves 311 are provided on the inner top wall of the connecting plate 2. The T-shaped slider 310 and the T-shaped slide groove 311 are slidably connected. The tooth plate 307 drives the moving block 308 to move, which can drive the limit block 309 to move, so as to facilitate the subsequent fixed stacking between the sealed cartons 1.

[0027] At the same time, the limiting component includes fixed blocks 312 fixed on the left and right sides of the upper surface of the sealed carton 1, and fixed grooves 313 are provided on the opposite sides of the two fixed blocks 312. The limiting component also includes a limiting block 309 fixed to the bottom of the moving block 308 and extending to the outside of the connecting plate 2. Two moving holes are provided on the lower surface of the connecting plate 2. The moving holes and the limiting blocks 309 are slidably connected. The cross-section of the limiting block 309 is L-shaped. The limiting block 309 and the fixed groove 313 are slidably connected. The limiting block 309 is moved out of or into the fixed groove 313 by adjusting the positions of the limiting block 309 and the fixed groove 313, thereby achieving stable stacking between the sealed cartons.

[0028] It should be noted that by adjusting the operating connecting plate 2, the two sealed cartons 1 can be stably stacked, so that during transportation or storage, the stacked sealed cartons can further avoid movement or overturning due to external forces, resulting in damage to the cartons and internal items, and indirectly improves subsequent handling efficiency.

[0029] The working principle of the above embodiment is:

[0030] When it is necessary to stack the sealed cartons 1 that have been loaded with items and sealed, first stack the sealed cartons 1 so that the lower surface of the connecting plate 2 contacts the upper surface of the fixed block 312, and then turn the handle 302 to drive the worm 301 and the worm wheel 303 to rotate, so that the rotating rod 304 and the two gears 305 start to rotate, and then the two sets of toothed plates 307 respectively drive the two moving blocks 308 and the limit block 309 to move in opposite directions. At this time, the movement of the moving block 308 will drive the T-shaped slider 310 to move along the T-shaped slide groove 311, further providing support for the movement of the moving block 308 and the limit block 309, so that the limit block 309 can move more Stable until the limit block 309 moves into the interior of the fixing groove 313 and fits with its inner wall. At this time, the position of the fixing block 312 and the connecting plate 2 can be fixed, and then the sealed cartons 1 can be stably fixed, so that the stable stacking of the two sealed cartons 1 can be achieved. At the same time, operation according to the above principle is also convenient for separating the two sealed cartons 1. By operating according to the above principle, the risk of the stacked sealed cartons being moved or overturned by external forces during transportation or storage can be effectively reduced, thereby protecting the internal items from damage. At the same time, the storage space can be used more effectively, the space utilization rate can be improved, and it is also more convenient for the subsequent handling of the cartons, so that the handling process can be more efficient.
