Description

A quick-release, tape-free agricultural product packaging box Technical Field

[0001] This utility model relates to the field of logistics packaging box technology, and in particular to a quick-release tape-free agricultural product packaging box. Background Technology

[0002] Tape-free logistics packaging boxes can reduce the use of tape and meet current environmental protection requirements. Conventional logistics packaging boxes use multiple buckle structures for interference fit to enhance the stability of the packaging seal. This makes it time-consuming and laborious to unpack the packaging box, and it is easy to damage the buckle structure, affecting the reuse of the packaging box when returning or exchanging goods. When returning or exchanging goods, tape is required to seal the box again.

[0003] Most agricultural products have their own packaging bags. Packaging boxes mainly serve as outer protection and for attaching express delivery labels. They do not need to be completely sealed. When sealing without tape, they should be reusable multiple times and have good sealing stability. In existing technologies, the buckle structure is generally hidden, which makes it difficult to disassemble and easily damaged. This problem needs to be solved. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a quick-release, tape-free agricultural product packaging box, which addresses the above-mentioned technical deficiencies and solves the problem that the buckle structure in the prior art is not easy to disassemble and is easily damaged.

[0005] The technical solution adopted by this utility model is: to provide a quick-release, tape-free agricultural product packaging box, comprising:

[0006] The main body has side top plates on both the left and right sides at the top. The front end of the main body has a first bayonet and a second bayonet, with the second bayonet located above the first bayonet.

[0007] The upper cover is opened and closed at the upper end of the main body and located above the side top plate. The rear side of the upper cover is connected to the upper rear side of the main body. The front end of the upper cover has a locking part. The locking part passes through the first bayonet from the inside of the main body to the outside and then folds upward. The second bayonet is used to insert the end of the locking part. One side of the locking part has a slot, which is used to engage with the side wall of the first bayonet.

[0008] Further optimization of this technical solution also includes:

[0009] A locking strip is disposed at the front end of the main body and opposite to the second locking position. The locking strip and the front end of the main body form a locking channel, which is used to engage the end of the locking part.

[0010] To further optimize this technical solution, the front end of the main housing has two vertically opposite slits, the main housing between the two slits forms the locking strip, and the two slits form the second locking opening.

[0011] To further optimize this technical solution, the end of the locking part has a side edge, which is used to abut against the upper end of the card strip or to pass through the second bayonet and engage with the inside of the main housing.

[0012] To further optimize this technical solution, the second bayonet and the first bayonet are offset to the left and right, and the second bayonet is offset relative to the first bayonet towards the side of the card slot.

[0013] To further optimize this technical solution, the front left and right sides of the main housing are provided with the first bayonet and the second bayonet, and the front left and right sides of the upper cover are provided with locking parts.

[0014] To further optimize this technical solution, both the front and rear sides of the side top plate have downward folded portions, and the end faces of the downward folded portions are used to abut against the inner wall of the main box.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The top cover is placed on the top of the main body for sealing. The locking part passes through the first bayonet from the inside to the outside, then folds upward and passes through the second bayonet from the outside to the inside. The locking part is positioned by friction, bending, and slot engagement with the first and second bayonet, which can achieve good positioning stability. When disassembling, the operable parts of the locking part are in the open, which makes it easier to complete the disassembly and open the top cover under observation, reducing damage to the locking part and the main body, and is conducive to multiple recycling.

[0017] 2. The main body and the top cover can be integrated into a single cardboard box structure, eliminating the need for additional components. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0031] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] As shown in Figures 1-10, a quick-release, tape-free agricultural product packaging box includes: a main body 1 with side top plates 2 on both the left and right sides of the upper end; a first latch 101 and a second latch 102 at the front end of the main body 1, with the second latch 102 located above the first latch 101; an upper cover 3, which is opened and closed at the upper end of the main body 1 and located above the side top plates 2; the rear side of the upper cover 3 is connected to the upper rear side of the main body 1; the front end of the upper cover 3 has a locking part 301, which passes through the first latch 101 from the inside of the main body 1 and then folds upward; the second latch 102 is used to insert the end of the locking part 301; and a slot 3011 is provided on one side of the locking part 301 for engaging with the side wall of the first latch 101.

[0034] In use, the main box 1 and the upper cover 3 can be made of corrugated cardboard as a whole. The main box 1 can be composed of existing technologies, which are not shown in this application. After the agricultural products are placed inside the main box 1, the side top plates 2 on both sides are covered, and then the top cover plate 3 is covered. The top cover plate 3 seals the upper end of the main box 1. The locking part 301 is a part of the outer extension of the top cover plate 3. Before the top cover plate 3 is completely closed, the locking part 301 moves downward into the inner side of the main box 1, and the end protrudes from the first slot 101 to the outer side of the main box 1. Then the top cover plate 3 is completely closed to cover the upper end of the main box 1. The locking part 301 is pulled outward and the card slot 3011 is engaged with the side wall on one side of the first slot 101. The locking part 301 is folded upward and the end of the locking part 301 is inserted from the outside to the inside into the second slot 102. Then the end of the locking part 301 is located between the root of the locking part 301 (the end connected to the main body of the top cover) and the inner wall of the main box 1, thus finally fixing the top cover plate 3. When it is necessary to disassemble and open the top cover 3, hold the locking part 301 located on the outside of the main body 1 between the first latch 101 and the second latch 102, pull the end out from the second latch 102, then straighten the locking part 301 downwards, push the locking part 301 upwards and at the same time lift the top cover 3 upwards, then the top cover 3 can be opened, and the locking part 301 and the structure of the main body 1 are less damaged.

[0035] When the locking part 301 passes through the first bayonet 101, it can be either an interference fit or a clearance fit. Through folding and the limiting of the second bayonet 102, it can provide good positioning capability. At the same time, the lock can be engaged with the side wall of the first bayonet 101 to enhance positioning.

[0036] Furthermore, it also includes: a locking strip 103, which is disposed at the front end of the main housing 1 and opposite to the second locking slot 102. The locking strip 103 and the front end of the main housing 1 form a locking channel 1031, which is used to lock the end of the locking part 301.

[0037] The front end of the main body 1 has two vertically opposite slits 104. The main body 1 between the two slits 104 forms a retaining strip 103, and the two slits 104 form a second retaining opening 102.

[0038] The locking part 301 has a side edge 3012 at its end, which is used to abut against the upper end of the locking strip 103 or to pass through the second bayonet 102 and engage with the inside of the main housing 1.

[0039] When in use, the locking strip 103 and the main body 1 form a locking channel 1031. The locking channel 1031 is connected to the second locking slot 102. After the locking part 301 is folded upward, it can either be inserted into the second locking slot 102 or pass through the locking channel 1031 from bottom to top. Both methods can position the end of the locking part 301.

[0040] The locking part 301 passes through the locking channel 1031 and can be engaged with the locking strip 103 by the side edge 3012 of the side of the locking part 301, thereby enhancing the fixing stability.

[0041] The locking strip 103 can be an additional component, such as a plastic part, fixed on both sides of the second latch 102. As shown in Figure 9, the locking strip 103 can also be integrally formed by cutting the front end of the main body 1. Two parallel and spaced slits 104 are cut at the front end of the main body 1, and the excess material between the two slits is the locking strip 103. Through its own deformation or bending, the locking strip 103 protrudes from the front end of the main body 1. When the end of the locking part 301 is inserted into the second latch 102, the presence of the locking strip 103 can enhance the positioning ability of the end of the locking part 301. The width of the second latch 102 can be slightly wider than the width of the end of the locking part 301, so that the end of the locking part 301 can pass through the second latch 102 or through the locking channel 1031.

[0042] Furthermore, the second bayonet 102 and the first bayonet 101 are offset to the left and right, and the second bayonet 102 is offset relative to the first bayonet 101 towards the side of the card slot 3011.

[0043] In use, the second latch 102 and the first latch 101 are offset to the left and right. After the locking part 301 passes through the first latch 101, it folds upward and enters the second latch 102 or the locking channel 1031. The locking part 301 is in an inclined state or is biased to one side of the slot 3011. For example, if the slot 3011 is located on the left side of the middle of the locking part 301, the second latch 102 is offset to the left by 1-3 mm relative to the first latch 101. After the locking part 301 passes through the first latch 101, it is offset to the left and tilted. This allows the slot 3011 to be more stably engaged with the left side wall of the first latch 101, improving stability. When disassembling, a slight pulling force is applied to the right to disengage the slot 3011 from the side wall of the first latch 101. By offsetting the position of the locking part 301 through the first bayonet 101, the locking part 301 can be in a gap fit with the first bayonet 101. That is, there is a gap between the right side of the locking part 301 and the right side wall of the first bayonet 101. When the slot 3011 is disengaged from the left side wall of the first bayonet 101, the locking part 301 can quickly and safely disengage from the first bayonet 101.

[0044] Furthermore, the front left and right sides of the main body 1 are provided with a first bayonet 101 and a second bayonet 102, and the front left and right sides of the upper cover 3 are provided with locking parts 301.

[0045] In use, the locking part 301, together with the first bayonet 101 and the second bayonet 102, forms a closed structure. Multiple closed structures can be provided depending on the required stability. Closed structures can be installed on both the left and right sides of the front end of the main housing 1 to enhance stability, and the two locking parts 301 are also easy to disassemble.

[0046] Furthermore, both the front and rear sides of the side top plate 2 have downward folding portions 201, the end faces of which are used to abut against the inner wall of the main body 1.

[0047] During use, the lower folds 201 on both the front and rear sides of the side top plate 2 are separated from the side wall of the main box 1, meaning the connection between the front and rear sides of the side top plate 2 and the main box 1 is cut off by a cutter. When the main box 1 is not full, air bags can be added to enhance anti-collision and stability. Alternatively, the lower folds 201 can be bent downwards, so that the lower folds 201 and the main body of the side top plate 2 are bent, thus strengthening the structural strength of the side top plate 2. The end face of the lower folds 201 near the inner wall of the main box 1 abuts against the inner wall of the main box 1, which can support the side top plate 2 and press down on the packaged goods, enhancing the stability of the internal fixation and the stability of the support for the top cover 3, and reducing the risk of incomplete sealing caused by the top cover 3 sinking.

[0048] A bending structure 302 can be set at the middle of the front end of the top cover plate 3 to strengthen the overall strength and improve the sealing of the upper part of the main box 1. A downward bending structure 302 can be set at the locking part 301 of the top cover plate 3 and at other positions on the three sides to fasten to the outer side of the upper part of the main box 1.
