Description

Technical Field

[0001] The present invention relates to the technical field of goods transfer containers, and particularly relates to a turnover box with a goods lashing device. Background Art

[0002] In the existing fresh food and flower industries, most use cardboard boxes for transportation. Disposable consumables such as packing straps, packing buckles, and tapes are often used when packing goods, which easily causes waste of resources and increases the difficulty of packing operations.

[0003] In the prior art, plastic turnover boxes with lids are also used for transportation. The box body of the turnover box is equipped with lashing straps. Usually, there are two lashing straps, which are respectively installed on the left and right inner side walls of the box body. One end of the lashing strap is fixed to the box body, and the other end is equipped with a buckle. When the goods are loaded, it is necessary to tightly hold the lashing strap to tighten the goods and fasten the buckle to fix the goods. When the goods are loaded relatively full, it is difficult to operate only by manually tightening the lashing strap to tie up the goods.

[0004] The common material of the buckle of the existing lashing strap is plastic. When the goods expand outwards, the plastic buckles are relatively easy to disengage from each other, resulting in the failure of the lashing strap. And generally, the lashing strap cannot be adjusted after being fixed to the box body. When using the lashing strap for different goods, lashing straps at different positions are often required. The fixed form of the lashing strap limits the scenarios of loading different goods. In addition, since the front end of the lashing strap cannot be fixed to the box body, it often falls into the box during boxing, and it is necessary to turn the lashing strap outside the box again and again, which reduces the operation convenience and boxing efficiency.

[0005] Based on the existing deficiencies, the present invention provides a turnover box with a goods lashing device to improve the operation convenience and boxing efficiency of packing operations. Summary of the Invention

[0057] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so as to more clearly understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not limitations on the scope of the present invention, but only to illustrate the essential spirit of the technical solution of the present invention.

[0058] In the following description, certain specific details are set forth for purposes of explaining the various disclosed embodiments to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments may be practiced without one or more of these specific details. In other instances, well-known devices, structures and techniques associated with the present application may not be shown or described in detail so as to avoid unnecessarily obscuring the description of the embodiments.

[0059] Unless the context requires otherwise, throughout the specification and claims, the words "comprising" and its variations such as "comprises" and "having" shall be interpreted in an open, inclusive sense, i.e., construed to mean "including, but not limited to".

[0060] References to "an embodiment" or "one embodiment" in the specification throughout mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases "in an embodiment" or "in one embodiment" in various places throughout the specification are not necessarily all referring to the same embodiment. Additionally, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0061] As used in this specification and the appended claims, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise. It should be noted that the term "or" is generally used in its inclusive sense of "and / or" unless the context clearly dictates otherwise.

[0062] In the following description, for the purpose of clearly showing the structure and working mode of the present invention, many directional terms will be used for description. However, terms such as "front", "rear", "left", "right", "outer", "inner", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be construed as limiting terms.

[0063] Furthermore, terms such as "horizontal", "vertical", "hanging", etc. do not mean that the components are required to be absolutely horizontal or hanging, but may be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal compared to "vertical", and does not mean that the structure must be completely horizontal, but may be slightly inclined.

[0064] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0065] Such as Figure 1 and Figure 2As shown in the figure, the present invention provides a turnover box, which includes a box body and a cargo lashing device. The box body includes a base 11 and four side plates arranged in pairs opposite to each other. The four side plates are divided into a pair of long side plates 12 and a pair of short side plates 13. The pair of long side plates 12, the pair of short side plates 13 and the base 11 enclose a rectangular cavity for loading goods. In some cases, the lengths of the long side plates and the short side plates can also be the same, and a square cavity is formed at this time. Each side plate and the base are usually plastic parts, which can be made by existing processes such as thermoforming and injection molding.

[0066] Preferably, the side plates are connected to the base in a manner that can be folded relative to the base. In this embodiment, a plurality of edge guards extending in the thickness direction of the base are provided on the base 11. Each edge guard is arranged corresponding to one of the side plates, and a plurality of hanging grooves are provided on the inner side of each edge guard. Hooks corresponding to the hanging grooves are also provided at the bottom of each side plate. Each side plate can be pivotally connected to the base in a foldable manner relative to the base through the cooperation of the hooks at its own bottom and the corresponding hanging grooves. Another preferably, the box body further includes a box cover 14. One side of the box cover 14 is pivotally connected to the top of one of the long side plates 12, so that the box cover 14 can be flipped to cover the opening of the cavity and flipped to the outside of the long side plate to make the box body in an open state.

[0067] The cargo lashing device is used to fix the goods located in the box body. The base 11 of the box body is also the base of the cargo lashing device. The number of bundling mechanisms of the cargo lashing device is at least one group. Each group of bundling mechanisms includes a strap and a buckle device 23. In this embodiment, the strap is divided into a first strap 21 and a second strap 22. The first strap 21 and the second strap 22 are both strip-shaped structures, which are usually woven from artificial or natural fibers, but are not limited thereto. Other materials that meet the requirements can also be used to manufacture the strap. The number of bundling mechanisms can be adjusted according to the length of the box body.

[0068] One end of the first strap 21 is fixed inside the box body, and the other end is a free end. One end of the second strap 22 is fixed inside the box body on the side opposite to the first strap 21, and the other pair is fixedly connected to the buckle device 23. The buckle device 23 has a channel for the free end of the first strap 21 to pass through, and the buckle device 23 can lock and unlock the body of the first strap located in the channel, so as to achieve the purpose of self-locking and unlocking of the first strap 21, which can realize single-person operation and improve the operation convenience and efficiency. The strap can also be only one. At this time, the buckle device can be directly fixed on the base or the side plate. The strap passes through the buckle device and locks it. Or the middle part of a strap is fixed on the base or the side plate, one end is fixed with the buckle device, and the other end passes through the buckle device and locks it.

[0069] See Figures 2 - 4 where Figure 3The schematic diagram shows the buckle device 23 locking the first strap 21. Figure 4 The schematic diagram shows the buckle device 23 unlocking the first strap 21. The buckle device 23 includes a buckle frame 231, a first limiting portion 232, a second limiting portion 233, and a buckle 234. The buckle frame 231 shown in the figure is composed of two oppositely arranged sheet bodies. Both the first limiting portion 232 and the second limiting portion 233 are columnar structures, and their two ends are respectively connected to the two sheet bodies to form a generally rectangular frame structure. The buckle 234 is rotatably installed in the space formed by the two sheet bodies of the buckle frame 231 through a buckle mounting shaft 235, and the buckle 234 has a button limiting portion 2341 oppositely arranged with the first limiting portion 232. The distance between the button limiting portion 2341 and the first limiting portion 232 forms a channel 230 for the first strap 21 to pass through. The button limiting portion 2341 includes a first limiting surface 2342 and a second limiting surface 2343. As the buckle 234 rotates, the button limiting portion 2341 has a locking state where the first limiting surface 2342 faces the first limiting portion 232 and an unlocking state where the second limiting surface 2343 faces the first limiting portion 232. In the locking state, the distance between the first limiting surface 2342 and the first limiting portion 232 is less than the thickness of the first strap 21. At this time, the button limiting portion 2341 and the first limiting portion 232 cooperate to lock the first strap 21. In the unlocking state, the distance between the second limiting surface 2343 and the first limiting portion 232 is greater than the thickness of the first strap 21. At this time, the first strap 21 can freely pass through the channel 230, and thus the tightness of the bundling can be adjusted and the untying operation can be performed. In addition, the buckle in this embodiment can also achieve locking and unlocking operations through other displacement methods relative to the buckle frame. For example, the distance between the button limiting portion and the first limiting portion can be adjusted by the sliding displacement of the buckle relative to the buckle frame to achieve the locking and unlocking of the strap. The aforementioned first limiting surface and second limiting surface can also be one or more convex point structures instead of continuous surfaces.

[0070] As Figure 5As shown in the figure, the first limiting portion 232 has a limiting plane 2321 disposed opposite to the button limiting portion 2341. The upper and lower ends of the limiting plane 2321 form arc surfaces 2322 that bend away from the button limiting portion 2341. The arc surfaces 2322 can reduce the wear of the first limiting portion 232 on the first strap 21. In the locked state, the limiting plane 2321 is disposed substantially parallel to the first limiting surface 2342. At this time, the distance between the first limiting surface 2342 and the first limiting portion 232 is the distance between the limiting plane 2321 and the first limiting surface 2342. Preferably, the distance between the upper part of the first limiting surface 2342 and the button rotation axis is greater than the distance between the lower part of the first limiting surface 2342 and the button rotation axis. When the first strap 21 is pulled back, the upper part of the first limiting surface 2342 can make the distance between the limiting plane 2321 and the first limiting surface 2342 smaller, making the button limiting portion 2341 lock the first strap 21 more tightly, thereby preventing the first strap 21 from loosening.

[0071] Preferably, a protrusion 2344 can also be provided on the first limiting surface 2342 to increase the friction between it and the first strap 21, further increasing the stability of the first strap 21 in the locked state to avoid loosening.

[0072] The second limiting surface 2343 is an inclined surface disposed obliquely away from the first limiting portion 232, and it is disposed at an angle with the first limiting surface 2342. So that in the unlocked state, the distance between the second limiting surface 2343 and the first limiting portion 232 is greater than the thickness of the first strap 21, enabling the first strap 21 to move within the distance to achieve adjustment of the binding tightness and the unlocking operation.

[0073] Refer to again Figure 3 and Figure 4 As shown in FIGS. and, the buckle device 23 further includes a reset member 236. The reset member 236 generates a force to reset the buckle 234 to the locked state, so that it remains in the locked state without external force. The reset member 236 in this embodiment is a torsion spring, and its main body is sleeved on the outer periphery of the buckle mounting shaft 235. The two fixed feet of the torsion spring are respectively supported on the buckle 234 and the reset member limiting portion 237 protruding from the inner wall of the buckle frame 231. In practical applications, the reset member is not limited to a torsion spring, and other objects that can achieve the same function are also applicable here.

[0074] One end of the second strap 22 is fixedly connected to the second limiting portion 233 of the buckle device 23. In this embodiment, stitching is used to achieve the fixed connection between the two, but it is not limited thereto. Existing fixed connection methods such as rivet connection can also be used for the fixed connection.

[0075] Such as Figures 6 - 9As shown, the first strap 21 and / or the second strap 22 are fixed to the base 11 by a strap fixing member 3. The strap fixing member 3 includes a fixing member body 30, and the fixing member body 30 is detachably mounted on the base 11 in cooperation with the base 11. The fixing member body 30 includes a first limiting portion 31 and a second limiting portion 32 of the fixing member. The base 11 includes a base limiting portion 111 arranged in cooperation with the second limiting portion 32 of the fixing member and a base stop portion 112 arranged in cooperation with the first limiting portion 31 of the fixing member. The second limiting portion 32 of the fixing member and the base limiting portion 111 cooperate to limit the movement of the fixing member body 30 in the horizontal direction, and the first limiting portion 31 of the fixing member and the base stop portion 112 cooperate to limit the movement of the fixing member body 30 in the vertical direction.

[0076] Specifically, the base 11 further has an assembly groove 113 for accommodating the fixing member body 30. The base limiting portion 111 extends upward from the bottom of the assembly groove 113. The base limiting portion 111 is a convex block with a T-shaped cross-section in the horizontal direction, and the second limiting portion 32 of the fixing member is a groove matching the base limiting portion 111. When the fixing member body 30 is assembled into the assembly groove 113 of the base 11, the base limiting portion 111 is located within the base limiting portion 111, thereby restricting the movement of the fixing member body 30 in the horizontal direction. The base stop portion 112 is a clamping groove opened on the side wall of the assembly groove 113, and the first limiting portion 31 of the fixing member is a clamping block protruding in the horizontal direction on the fixing member body 30. When the fixing member body 30 is assembled into the assembly groove 113 of the base 11, the clamping block serving as the first limiting portion 31 of the fixing member is inserted into the corresponding clamping groove, thereby restricting the movement of the fixing member body 30 in the vertical direction. Of course, this is only a preferred installation solution provided in this embodiment, and other existing methods such as bolt fixing can also be used to fix the fixing member body 30 to the base 11. Preferably, the strap fixing member 3 is fixed to the base in a detachable manner. In addition, the thickness of the fixing member body 30 can be set to be equivalent to the width of the assembly groove 113, and the two are in clearance fit. Thus, the movement of the fixing member body 30 in the horizontal direction can be restricted through the clearance fit, that is, the fixing of the fixing member body 30 can be achieved only by the cooperation of the first limiting portion 31 of the fixing member and the base stop portion 112. The setting of the second limiting portion 32 of the fixing member and the base limiting portion 111 can strengthen the strength of the fixing member body 30 fixed in the assembly groove 113.

[0077] The fixing member body 30 further includes a fixing portion 33. One ends of the first strap 21 and the second strap 22 are slidably fixed to the fixing portion 33 of the corresponding fixing member body 30 and can slide along the fixing portion 33. The fixing portion 33 extends along the length direction of the corresponding side plate. For example, in this embodiment, the straps are fixed to the edge protection at one side of the base of the corresponding long side plate. Therefore, the distance between adjacent straps can be adjusted in the length direction of the long side plate to adapt to the goods loaded in the box and adjust the strap distance, with better applicability. Additionally, it can also be that the fixing member body is movably fixed to the base, and the distance between adjacent fixing member bodies is adjusted to achieve the distance between the straps. Or the fixing member body is movably fixed to the base, and a fixing portion is also provided on the fixing member to achieve a larger range of distance adjustment.

[0078] See Figure 10 and Figure 11 , Figure 10 and Figure 11 FIGS. show the first structure of the fixing portion 33. The fixing portion 33 includes a guiding main body 331 extending along the length direction of the corresponding side plate. One end of the guiding main body 331 is a connecting portion 332, and the other end is a guiding fixing portion 333. The connecting portion 332 is connected to the fixing member body 30, and the guiding fixing portion 333 can be fixedly connected to the fixing member body 30 by means such as snap fixing or pin fixing. The connecting portion 332 is hingedly connected to the fixing member body 30, and the hinged connection can be achieved by means such as a pin shaft to realize the hinged connection with the fixing member body 30. The hinged connection can also be that the connecting portion 332 and the fixing member body 30 in this embodiment are an integral part, and the elastic property of the connecting portion 332 is used to realize the rotatable hinged connection between the connecting portion 332 and the fixing member body 30.

[0079] The guiding fixing portion 333 at the other end of the fixing portion 33 is detachably connected to the fixing member body 30 to form an opening for installing the strap at the other end of the fixing portion 33. The guiding fixing portion 333 and the fixing member body can be detachably connected by means such as snap connection.

[0080] See Figure 12 and Figure 13 , Figure 12 and Figure 13 FIGS. show the second structure of the fixing portion 33. The fixing portion 33 is a pin shaft, and a pin hole 301 matching the pin shaft is provided on the fixing member body 30. The pin shaft is inserted into the pin hole 301 to fix the pin shaft.

[0081] See again Figure 9 and Figure 12, one end of the first strap 21 and the second strap 22 forms a sleeve portion that can be sleeved on the outer periphery of the fixing portion 33 through fixing means such as sewing. During installation, the sleeve portion is sleeved on the outer periphery of the fixing portion 33 and can slide along the fixing portion 33 to adjust the distance between adjacent straps.

[0082] See Figure 14 and Figure 15 , a base sliding cavity portion 114 is further provided on the base 11. The base sliding cavity portion 114 is provided with an opening above the corresponding fixing portion 33 to allow the strap to pass through the base sliding cavity portion 114 and slide along the fixing portion 33.

[0083] See Figure 16 and Figure 17 , a strap fixing portion 140 is provided on the inner wall of the box cover 14. The strap fixing portion 140 can be used to fix the first strap 21. When packing, the first strap 21 can be fixed on the strap fixing portion 140 of the box cover 14 to prevent it from falling into the box and affecting the packing operation. Since the second strap 22 is fixedly connected with the buckle device 23, when packing, the second strap together with the buckle device 23 can lean against the outside of the box body, and the weight of the buckle device 23 can well prevent it from falling into the box. Therefore, generally only fixing the first strap 21 can well avoid the problem that the strap falls into the box and affects the packing operation.

[0084] It should be noted that the first strap 21 in this embodiment is fixed on the base on the side connected with the box cover 14. When packing, the box cover 14 is flipped to the outside of the side plate, and at this time, the inner side of the box cover 14 faces outward. Therefore, a strap fixing portion 140 is provided on the inner side of the box cover 14. If the first strap 21 is fixed on the base on the side not connected with the box cover 14, at this time, the strap fixing portion 140 can be provided on the outside of the corresponding side plate to prevent the strap from falling into the box.

[0085] See again Figure 16 and Figure 17 , the strap fixing portion 140 includes a first strap limiting portion 141 and a second strap limiting portion 142. The first strap limiting portion 141 and the second strap limiting portion 142 are arranged in a staggered manner and form a channel for the first strap 21 to pass through. During the packing operation, first passing the first strap 21 through the channel formed by the first strap limiting portion 141 and the second strap limiting portion 142 can prevent the strap from falling into the box.

[0086] See Figure 18 and Figure 19 , Figure 18Another box structure is shown, where the box is formed by enclosing a cavity with a bottom plate and four side plates. The four side plates are divided into a pair of long side plates 12 and a pair of short side plates 13. The pair of long side plates and the pair of short side plates are arranged opposite to each other respectively. The bottom plate and the four side plates are integrally formed. The box further includes a box cover 14. One side of the box cover 14 is pivotally connected to the top of one of the long side plates 12 through a hinge, so that the box cover 14 can be flipped to cover the opening of the cavity and can be flipped to the outside of the long side plate to make the box in an open state.

[0087] See Figure 19 , the buckle device 23 is directly fixed to the side plate of the box. Specifically, a window 121 is provided on the long side plate. The buckle 234 is rotatably mounted on the box through a buckle mounting shaft 235 and is located within the window 121. A reset member 236 is sleeved on the outer periphery of the buckle mounting shaft 235 to generate a force for resetting the buckle 234 to the locked state, so that it remains in the locked state without external force.

[0088] The first limiting portion 232 is also directly provided on the box and is correspondingly arranged with the button limiting portion 2341 of the buckle 234, so that the distance between the button limiting portion 2341 and the first limiting portion 232 forms a channel 230 for the strap to pass through. The structural principle of the buckle 234 and the first limiting portion 232 for locking and unlocking the strap body passing through the channel 230 is the same as that of the above-described buckle device structure principle of the box, so it will not be elaborated here.

[0089] The preferred embodiments of the present invention have been described in detail above. However, it should be understood that after reading the above teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention. These equivalent forms also fall within the scope defined by the appended claims of this application.
