Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle parts packaging, in particular to a standpipe reinforcement plate packaging bottom box. Background Art

[0002] A motorcycle riser reinforcement plate is a crucial component of the motorcycle's body structure, primarily used to enhance the strength and stability of the riser. As a key component of the motorcycle frame, the riser bears the weight of the vehicle and various forces during driving. Therefore, the riser reinforcement plate ensures the riser's tightness and durability, preventing deformation or damage during driving.

[0003] The existing packaging method for riser reinforcement plates involves wrapping them in PE (polyethylene) bags, placing them in a paper box, and then placing them directly inside the box, securing the lid, and packaging for shipment. Because the riser reinforcement plates are sheet-like, the existing packaging method involves wrapping the surface of the riser with bubble wrap to prevent them from being squeezed and damaged. However, during transportation, the riser reinforcement plates within the box are prone to shifting and flipping laterally along their edges, causing damage and resulting in financial losses. Furthermore, due to the frequent handling and placement of the riser reinforcement plates during transportation, the bottom of the riser reinforcement plates is only separated by wrapping paper, and a paper box typically contains several riser reinforcement plates. This weight contributes to the weight of the riser reinforcement plates. When the box is placed on a platform, its weight may cause the bottom of the box to contact the platform with a certain force, which can easily damage the riser reinforcement plates that contact the bottom of the box. This results in poor packaging reliability for the riser reinforcement plates. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a bottom box for packaging a riser reinforcement plate to solve the problem of poor reliability of the riser reinforcement plate packaging.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a vertical tube reinforcement plate packaging bottom box including a supporting cover portion and a side surrounding portion arranged on the supporting cover portion for surrounding the vertical tube reinforcement plate on the supporting cover portion, and a supporting and limiting portion for supporting and limiting the movement of the vertical tube reinforcement plate is provided on the supporting cover portion and located inside the side surrounding portion, thereby dragging the bottom of the vertical tube reinforcement plate to prevent the bottom of the vertical tube reinforcement plate from being damaged due to picking up and placing during transportation, and at the same time playing a certain limiting role in the lateral direction to prevent the vertical tube reinforcement plate from shaking laterally during transportation and handling, thereby improving the reliability of the packaging.

[0006] Furthermore, an installation cavity with an open top is formed between the side surrounding portion and the supporting cover portion, and two support and limiting portions are provided corresponding to the installation cavity and are distributed in parallel and spaced apart in the installation cavity; the support and limiting portions include a bottom pressure structure provided in the installation cavity and a limiting groove provided on the bottom pressure structure for supporting and clamping the riser reinforcement plate, so as to limit the degree of freedom of the riser reinforcement plate to a certain extent and improve the protective safety of the riser reinforcement plate during transportation.

[0007] Furthermore, the support and limiting portion also includes a snap-in groove provided on the bottom pressure structure, and the bottom pressure structure is cross-clamped to the bottom of the side surrounding portion through the snap-in groove. The bottom pressure structure and the side surrounding portion are both supported on the support cover portion, thereby ensuring the supporting strength of the bottom pressure structure for the vertical tube reinforcement plate. At the same time, the cooperation between the bottom pressure structure and the side surrounding portion improves the structural strength and durability of the entire packaging box.

[0008] Furthermore, the side surrounding portion includes a plurality of first vertical plates arranged in parallel and at equal intervals along direction A and a plurality of second vertical plates arranged in parallel and at equal intervals along direction B. The plurality of second vertical plates are cross-intersected with each of the first vertical plates to form a plurality of installation cavities equally divided in a rectangular array between the support cover portion, so that multiple vertical pipe reinforcement plates can be installed at the same time, thereby reducing transportation costs.

[0009] Furthermore, the support limiting parts are grouped in two, and each row of the device cavities is passed through by a group of the support limiting parts that are clamped with the first vertical plate, and the limiting grooves are provided on the parts of each group of the support limiting parts located in each device cavity. The two support limiting parts of each group are symmetrically arranged between two adjacent second vertical plates, so that a group of support limiting parts cooperates with a row of device cavities, which not only reduces the production cost of the support limiting parts, but also improves the overall strength.

[0010] Furthermore, the bottom pressure structure includes a square pressure plate and a first folding structure formed on the pressure plate. The pressure plate is folded into a columnar structure through the first folding structure. The limiting groove and the snap-in groove are both formed on the pressure plate to reduce the manufacturing difficulty of the support limiting part.

[0011] Furthermore, the first folding structure includes three first folding lines, which are parallel and evenly spaced along the width direction of the pressing plate so that the pressing plate is sequentially divided into a first bottom plate, a first side plate, a second side plate, and a second bottom plate. The first side plate and the second side plate are bent along the first folding line between them, the first bottom plate is bent along the first folding line between it and the first side plate, and the second bottom plate is bent along the first folding line between it and the second side plate, and the first bottom plate and the second bottom plate are stacked and connected to form a triangular prism structure for easy manufacturing.

[0012] Furthermore, the snap-fit groove is formed at a position of the pressure plate corresponding to each first vertical plate, and the snap-fit groove includes two first through holes in a square shape that are mirror-imaged and respectively opened on the first side plate and the second side plate. The two first through holes are connected and the width is adapted to the thickness of the first vertical plate. The ends of the two first through holes extend back along the width direction to the corresponding first folding lines, so as to form the upward-opening snap-fit groove after being bent through the first folding lines. The bottom of the first vertical plate is cross-inserted into the snap-fit groove to realize the connection between the first vertical plate and the bottom pressure structure.

[0013] Furthermore, a first slot is provided on the first vertical plate at a position corresponding to the snap-fitting slot, through which the first bottom plate and the second bottom plate are inserted, so that when the first vertical plate and the bottom pressure structure are connected and matched, the bottoms of the first vertical plate and the bottom pressure structure are flush and contact the support cover part, thereby improving the connection stability.

[0014] Furthermore, the limiting groove is arranged between every two adjacent clamping grooves and is provided as at least one. The limiting groove includes two second through holes that are mirror-imaged and respectively opened on the first side plate and the second side plate and are V-shaped. The two second through holes are connected and bent along the first folding line to form the limiting groove open upward. The second through holes are adapted to the riser reinforcement plate so that it can be clamped therein, thereby realizing the limiting fixation of the riser reinforcement plate.

[0015] The standpipe reinforcement plate packaging bottom box of the present invention has at least the following beneficial effects: through the cooperation between the support cover portion and the side surrounding portion, the standpipe reinforcement plate can be surrounded therein, thereby preventing the standpipe reinforcement plate from contacting other parts from the bottom and the side, so as to play a packaging protection role; by arranging a support and limiting portion between the support cover portion and the side surrounding portion, the standpipe reinforcement plate can be dragged from the bottom, the interval between the standpipe reinforcement plate and the support cover portion is increased, the damage to the standpipe reinforcement plate caused by the ground during transportation and placement is reduced or even avoided, and its movement in the lateral direction is restricted, thereby improving the packaging stability and reliability.

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figures 1 to 6 As shown, the standpipe reinforcement plate packaging bottom box of the present invention includes a cover portion 1, a side surrounding portion 2 provided on the cover portion 1 for enclosing the standpipe reinforcement plate on the cover portion 1, and a support and limiting portion 3 provided on the cover portion 1 and the side surrounding portion 2. A device cavity with an open top is formed between the side surrounding portion 2 and the cover portion 1 for the standpipe reinforcement plate to be placed therein, and the support and limiting portion 3 is located in the device cavity. The cover portion 1 is used to support the cover portion 1 and the support and limiting portion 3, and the side surrounding portion 2 is used to enclose the standpipe reinforcement plate from the side to protect the standpipe reinforcement plate, thereby facilitating transportation; the support and limiting portion 3 is used to support and limit the movement of the standpipe reinforcement plate in the lateral direction, so that the bottom of the standpipe reinforcement plate is separated from the cover portion 1 and does not contact the cover portion 1. During the transportation and placement process, the force applied to the packaging box by the ground is transmitted to the standpipe reinforcement plate, thereby achieving effective protection of the standpipe reinforcement plate. It should be noted that the cover portion 1 , the side surrounding portion 2 and the support and limiting portion 3 in the present invention are all made of corrugated paper but are not limited to corrugated paper, which is not only low in cost but also recyclable.

[0028] In the context of this embodiment, the cover portion 1 includes a base plate 11 and a third first folding structure 312 formed on the base plate 11. The base plate 11 is made of, but not limited to, corrugated paper. The base plate 11 is a square sheet-like structure, which can be square or rectangular as needed. The second folding structure 12 includes two second fold lines 121 and two third fold lines 122 formed on the base plate 11. The two second fold lines 121 are parallel to two opposing sides of the base plate 11. The two second fold lines 121 are mirrored from the center of the base plate 11 on both sides of the base plate 11 near the side edges, thereby sequentially dividing the base plate 11 into a first enclosure 111, a fourth base plate 112, and a second enclosure 113. The first enclosure 111 and the second enclosure 113 are located on either side of the fourth base plate 112. The second fold lines 121 are located between the first enclosure 111 and the fourth base plate 112, and between the second enclosure 113 and the fourth base plate 112. The two third folding lines 122 are parallel to the other two opposite sides of the bottom support plate 11, so that the third folding lines 122 are perpendicular to the second folding line 121. The two third folding lines 122 are mirror-imaged from the center of the bottom support plate 11 on both sides of the bottom support plate 11 near the side edges to sequentially divide the bottom support plate 11 into a third enclosure 114, a fourth bottom plate 112, and a fourth enclosure 115. The third enclosure 114 and the fourth enclosure 115 are respectively arranged on the other two sides of the fourth bottom plate 112. The third folding lines 122 are located between the third enclosure 114 and the fourth bottom plate 112 and between the fourth enclosure 115 and the fourth bottom plate 112, and the second folding lines 122 are located between the third enclosure 114 and the fourth bottom plate 112 and between the fourth enclosure 115 and the fourth bottom plate 112. 121 and the third folding line 122 make the two ends of the third enclosure 114 intersect with the ends of the first enclosure 111 and the second enclosure 113 respectively, and make the two ends of the fourth enclosure 115 intersect with the ends of the first enclosure 111 and the second enclosure 113 respectively, and each intersecting part is defined as an end panel 117, and the end panel 117 is connected to the first enclosure 111 or the second enclosure 113, and the end panel 117 is disconnected from the adjacent third enclosure 114 or fourth enclosure 115 by splitting. The first, second, third, and fourth panels 111, 113, 114, and 115 are all bent vertically upward to enclose a cavity with an open top. The end panels 117 at both ends of the first and second panels 111, 113 are connected to the corresponding third and fourth panels 114, 115, respectively, by gluing or nailing. This folded arrangement forms the cover support portion 1. The side panel 2 is supported by the fourth bottom panel 112 and is located within the cavity of the cover support portion 1. To ensure an aesthetically pleasing appearance of the cover support portion 1, the first, second, third, and fourth panels 111, 113, 114, and 115 are all of the same width. Handle holes 116 are symmetrically provided on two of the enclosures, such as the first enclosure 111 and the second enclosure 113, or on the third enclosure 114 and the third enclosure 114, so that the transporters can increase the gripping force between the packaging base and their hands through the handle holes 116, thereby facilitating the transporters to move the packaging boxes.

[0029] In this embodiment, the side surrounding portion 2 includes a plurality of first vertical plates 21 arranged in parallel and at equal intervals along direction A and a plurality of second vertical plates 22 arranged in parallel and at equal intervals along direction B. The length directions of the first vertical plates 21 are distributed along direction B, and the length directions of the second vertical plates 22 are distributed along direction A. The plurality of second vertical plates 22 are cross-intersected with each first vertical plate 21 to form a plurality of equally divided device cavities in a rectangular array between the support cover portion 1, so that the first vertical plates 21 and the second vertical plates 22 are arranged in a grid shape and a plurality of vertical tube reinforcement plates can be installed, thereby improving the accommodation capacity and reducing the packaging and transportation costs. In the content defined in this embodiment, the first vertical plate 21 and the second vertical plate 22 are both rectangular sheet structures, and the length of the first vertical plate 21 is the same as the length of the fourth bottom plate 112 or the length of the third panel 114, and the length of the second vertical plate 22 is the same as the width of the fourth bottom plate 112 or the length of the first panel 111, so that after the cover support portion 1 is folded, the two ends of the first vertical plate 21 respectively abut against the first panel 111 and the second panel 113, and the two ends of the second vertical plate 22 respectively abut against the third panel 114 and the fourth panel 115, thereby mutually supporting the first and second vertical plates 21, 22 and the cover support portion 1, thereby improving the strength and reliability of the overall packaging box. A first socket 211 is provided on the bottom side of the first vertical plate 21 at a position corresponding to each second vertical plate 22. The first socket 211 is a square groove and its width is consistent with the thickness of the second vertical plate 22 to adapt to it. On the top side of the second vertical plate 22, corresponding to each first socket 211, a second socket 221 is provided, connected to the first socket 211. The second socket 221 is a square slot with a width that matches the thickness of the first vertical plate 21. The sum of the lengths of the first socket 211 and the second socket 221 is equal to the width of the first vertical plate 21 or the second vertical plate 22, so that the first socket 211 and the second socket 221 complement each other. After insertion, the first vertical plate 21 and the second vertical plate 22 intersect with each other, with their bottom and top sides flush, thereby forming a plurality of device cavities distributed in a rectangular array. Each device cavity is arranged in multiple rows and columns, with the rows in the A direction and the columns in the B direction, to ensure the stability of the side surrounding portion 2. It should be noted that at least two first vertical plates 21 and second vertical plates 22 are provided to ensure the formation of the device cavities. To prevent the panels from being bumped by side objects during transport, which could affect the use of the riser reinforcement plates within the installation cavity, each first and second vertical plate 21, 22 has tail ends outside the installation cavity after assembly. The tail ends are of uniform width. This ensures that after the side panel 2 is installed on the cover portion 1, each tail end abuts against the corresponding panel, separating the side walls of each installation cavity from the panels. This prevents any lateral impact during transport from affecting the riser reinforcement plates within the installation cavity. Correspondingly, the support and limiter 3 can also have tail ends at both ends.

[0030] In this embodiment, two support and limiting portions 3 are provided in each device cavity, parallel to each other and spaced apart. As an example, two support and limiting portions 3 can be provided in each device cavity. Accordingly, the number of support and limiting portions 3 is equal to the number of device cavities multiplied by two. Preferably, the support and limiting portions 3 are arranged in groups of two, and each device cavity in each row is penetrated by a group of support and limiting portions 3 that engage with the first vertical plate 21. This allows for as many groups of support and limiting portions 3 as there are rows of device cavities. Each device cavity in each row is connected by a group of support and limiting portions 3. While ensuring support and positioning for the riser reinforcement plates in each device cavity in each row, the support and limiting portions 3 enhance the securement and reliability of the connection between the first vertical plates 21, thereby increasing the overall strength of the packaging box. The two support and limiting portions 3 in each group are symmetrically arranged between two adjacent second vertical plates 22, spaced apart from the second vertical plates 22, so that the bottom of the riser reinforcement plate, near the middle, engages with the support and limiting portions 3.

[0031] In the content defined in this embodiment, the support and limiting portion 3 includes a bottom pressure structure 31 provided in the device cavity, a limiting groove 32 provided on the bottom pressure structure 31, and a clamping groove 33 provided on the bottom pressure structure 31. The bottom pressure structure 31 is cross-clamped to the bottom of the side surrounding portion 2 through the clamping groove 33 to achieve a connection between the bottom pressure structure 31 and the first vertical plate 21. The limiting groove 32 is used to support and clamp the vertical pipe reinforcement plate to separate the vertical pipe reinforcement plate and the supporting cover portion 1, while limiting the movement of the vertical pipe reinforcement plate to prevent the vertical pipe reinforcement plate from shaking and bumping during transportation.

[0032] In the context of this embodiment, the bottom pressure structure 31 includes a square pressure plate 311 and a first folding structure 312 formed on the pressure plate 311. The pressure plate 311 is a rectangular sheet structure that is folded into a columnar structure by the first folding structure 312. The limiting groove 32 and the engaging groove 33 are both formed on the pressure plate 311, and each portion of the pressure plate 311 supporting the limiting portion 3 located in each device cavity is provided with a limiting groove 32. In this embodiment, the first folding structure 312 includes three first folding lines 3121. The three first folding lines 3121 are parallel and evenly spaced along the width direction of the pressure plate 311. Each first folding line 3121 sequentially divides the pressure plate 311 into a first bottom plate 3111, a first side plate 3112, a second side plate 3113, and a second bottom plate 3114. When used as a packaging box, the first side panel 3112 and the second side panel 3113 are bent along the first folding line 3121 between them to form a V shape, the first bottom panel 3111 is bent along the first folding line 3121 between the first side panel 3112 toward the second side panel 3113, and the second bottom panel 3114 is bent along the first folding line 3121 between the second side panel 3113 toward the first side panel 3112. Finally, the first bottom panel 3111 and the second bottom panel 3114 are stacked together and connected by gluing or other means to make the support and limiting portion 3 have a triangular prism structure, and the side where the first bottom panel 3111 is located faces the side of the fourth bottom panel 112 of the cover portion 1, and the first side panel 3112 and the second side panel 3113 are arranged toward the first vertical panel 21 to match the first vertical panel 21. It should be noted that since the pressing plate 311 is made of corrugated paper, and the corrugated paper has a certain thickness, the width of the first side panel 3112 and the second side panel 3113 are the same, and the width of the first bottom panel 3111 is smaller than the width of the second bottom panel 3114, and the difference between the widths of the first bottom panel 3111 and the second bottom panel 3114 is the thickness of the pressing plate 311.

[0033] In the content defined in this embodiment, the snap-in slot 33 is formed at the position of the pressing plate 311 corresponding to each first vertical plate 21, and the snap-in slot 33 includes two first through holes 331 that are mirror-imaged and respectively opened on the first side plate 3112 and the second side plate 3113 and are square. The two first through holes 331 extend toward each other on the first folding line 3121 between the first side plate 3112 and the second side plate 3113 to be connected, and the width of the two first through holes 331 is the same as that of the first vertical plate 3112. 21 is adapted to the thickness of the first vertical plate 21, and the opposite ends of the two first through holes 331 extend in opposite directions along the width direction of the pressure plate 311 to the adjacent first folding lines 3121. When the pressure plate 311 is bent at the first folding line 3121, the two first through holes 331 form a V-shaped or triangular snap-in groove 33 that is open upward. During assembly, the bottom of the first vertical plate 21 is cross-inserted into the snap-in groove 33. At this time, the first vertical plate 21 is against the first bottom plate 3111. To ensure that the support-limiting portion 3 and its bottom are flush with the side panel 2, a first slot 212 is provided on the first vertical plate 21 at a position corresponding to the snap-in slot 33, through which the first bottom plate 3111 and the second bottom plate 3114 pass. The first slot 212 is trapezoidal in shape, corresponding to the first and second bottom plates 3111, 3114, and its width is equal to the sum of the thicknesses of the first and second bottom plates 3111, 3114. This ensures that, after the first vertical plate 21 is cross-engaged with the pressure plate 311, the support-limiting portion 3 and the bottom surface of the first vertical plate 21 are flush, thereby increasing the contact area with the cover support portion 1 and improving stability. It should be noted that the first slot 212 is spaced apart from the first socket 211 and is independently provided, so that the two support-limiting portions 3 are spaced apart from the second vertical plate 22.

[0034] In the context of this embodiment, a limiting groove 32 is provided between each pair of adjacent engaging grooves 33. At least one, and typically two, are provided. This means that two riser reinforcement plates can be installed in each installation cavity. The two limiting grooves 32 are spaced apart and arranged in mirror-image fashion on the pressure plate 311. The limiting grooves 32 include two V-shaped second through holes 321, mirror-imaged on the first side plate 3112 and the second side plate 3113. The openings of the two second through holes 321 face each other and extend to a second fold line 3122 between the first side plate 3112 and the second side plate 3113 to communicate with each other. The opposing ends of the two first through holes 331 extend in opposite directions along the width of the pressure plate 311 to adjacent first fold lines 3121. The width of the openings of the two first through-holes 331 is greater than the thickness of the riser reinforcement plate to accommodate the riser reinforcement plate and allow it to pass therethrough. The width of a certain location in the middle of the two first through-holes 331 is equal to the thickness of the riser reinforcement plate. When the pressure plate 311 is bent along the first folding line 3121, the two second through-holes 321 form upwardly open, V-shaped retaining grooves 32. During assembly, the bottom sides of the riser reinforcement plate are inserted into the two retaining grooves 32 corresponding to the two support retaining portions 3. The V-shaped second through-holes 321 allow the riser reinforcement plate to be inserted and locked in a certain location in the middle of the retaining grooves 32. At this point, the riser reinforcement plate is spaced apart from the fourth bottom plate 112 and is restricted in the A direction. The B direction is restricted by the second vertical plate 22.

[0035] The working method of one embodiment of the standpipe reinforcement plate packaging bottom box of the present invention is as follows: the first standpipe 21, the second standpipe 22 and the pressure plate 311 are folded and connected to each other and then placed on the fourth bottom plate 112, and each enclosure (referring to the first enclosure 111, the second enclosure 113, the third enclosure 114 and the fourth enclosure 115) are arranged on the tail ends of the first standpipe 21 and the second standpipe 22, and the two sides of the standpipe reinforcement plate are respectively clamped in the limiting groove 32 to complete the support and limitation of the standpipe reinforcement plate.
