Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle parts packaging, in particular to a vehicle seat cushion branch pipe packaging structure. Background Art

[0002] The motorcycle seat branch pipe, also known as the seat tube or seat bow, is the supporting component under the motorcycle seat. It connects the seat and the frame, and plays a supporting and fixing role. Therefore, the seat branch pipe not only bears the weight of the seat, but also bears the weight of the rider as well as the vibration and impact during driving.

[0003] The existing packaging method of the seat cushion branch pipe is as follows: the seat cushion branch pipe is wrapped with a PE (PE: polyethylene) bag, then placed in a paper cushion box, and then directly placed in the paper box, covered with a lid, and then packaged for shipment. Since the seat cushion branch tube is a sheet structure, in order to avoid squeezing and damaging the seat cushion branch tube, the existing packaging method is to wrap bubble film on the surface of the vertical tube. However, the seat cushion branch tube in the packaging box is prone to movement during transportation, and may flip sideways along the edge, causing the seat cushion branch tube to be damaged by bumps, thereby causing economic losses; some existing packaging boxes are provided with a limit bar with a top slot at the bottom. By inserting the components into the slot of the limit bar from top to bottom, the components including the seat cushion branch tube are limited from shaking in the lateral direction, thereby improving the stability of the components, but there is still shaking in the vertical direction during transportation. The existing limit bar structure cannot achieve vertical limit, and the seat cushion branch tube is still likely to be damaged by bumps during transportation; or a hole is opened on the side of the limit bar to pass the end of the seat cushion branch tube through it to achieve lateral and vertical limit. However, since the seat cushion branch tube is not a straight rod, the method of passing both ends of the seat cushion branch tube through the holes on the side of the limit bar increases the difficulty of installation. 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 vehicle seat cushion branch pipe packaging structure to solve the problem of poor reliability of the existing seat cushion branch pipe packaging.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a vehicle seat cushion branch tube packaging structure including a support cover part and a limiting unit arranged on the support cover part, the limiting unit including a first limiting part and a second limiting part arranged on the support cover part and spaced apart and parallel to each other, the first limiting part having a first limiting structure for allowing one end of the seat cushion branch tube to pass through horizontally and restricting the movement of the seat cushion branch tube in the horizontal and vertical directions, the second limiting part having a second limiting structure for allowing the other end of the seat cushion branch tube to pass through vertically and restricting the movement of the seat cushion branch tube in the horizontal and vertical directions, so as to facilitate the installation of the seat cushion branch tube and facilitate the horizontal and vertical limiting fixation of the two ends of the seat cushion branch tube.

[0006] Furthermore, the first limiting portion and the second limiting portion both have a first mating surface located at the top and a second mating surface adjacent to the first mating surface, and the first limiting portion and the second mating surfaces of the second limiting portion are arranged facing each other; the first limiting structure is formed on the first mating surface of the first limiting portion, and the second limiting structure is formed on the first mating surface and the second mating surface of the second limiting portion, thereby facilitating the installation and limitation of both ends of the seat cushion branch pipe.

[0007] Furthermore, the first limiting structure includes a first contoured opening formed on a second mating surface of the first limiting portion to adapt to one end of the seat cushion branch tube. The first contoured opening is open toward the side of the opposite second limiting portion and is sealed at the top and bottom, so that after the first contoured opening is passed through one end of the seat cushion branch tube, its movement is restricted in the lateral and vertical directions, thereby ensuring the stability of the seat cushion branch tube and the packaging safety.

[0008] Furthermore, the first limiting portion includes a first pressing plate with a rectangular sheet structure and a first folding structure formed on the first pressing plate to fold the first pressing plate into a square; the first folding structure includes three first folding lines distributed in sequence along the width direction of the first pressing plate, the length direction of each first folding line is arranged along the length direction of the first pressing plate so that the first pressing plate is sequentially divided into a first bottom plate, a first side plate, a first top plate and a second side plate, the first side plate is vertically bent upward along the first folding line between the first bottom plate, the first top plate is horizontally bent toward the same side as the first bottom plate along the first folding line between the first side plate, the second side plate is vertically bent downward along the first folding line between the first top plate and the first bottom plate and connected to the first bottom plate to form a left side portion of the square tube shape, the first top plate is defined as the first mating surface, the first side plate is defined as the second mating surface, the first contour opening is formed on the first side plate, and the first bottom plate and the first top plate enable the top and bottom of the first contour opening to remain closed, thereby limiting the vertical freedom of the seat cushion branch pipe.

[0009] Furthermore, the first folding structure also includes three second folding lines distributed in sequence along the width direction of the first pressing plate, and each of the second folding lines is distributed on the first pressing plate in a mirror-image manner with each of the first folding lines to sequentially divide the first pressing plate into a third side panel, a second top panel and a fourth side panel, the third side panel is connected to the first bottom panel on the side away from the first side panel, the third side panel is vertically bent upward along the second folding line between the third side panel and the first bottom panel, the second top panel is horizontally bent toward the same side as the first bottom panel along the second folding line between the third side panel, the fourth side panel is vertically bent downward along the first fold between the second top panel and the second connection to form a square tube-shaped right side portion, the second top panel is defined as the first mating surface, the third side panel is defined as the second mating surface, and the second limiting portion is set to two corresponding to the left and right portions and is arranged on both sides outside the first limiting portion, so as to share the packaging structure with other products, increase the width direction size, and improve stability.

[0010] Furthermore, the second side panel and the fourth side panel are both provided with a protruding block on one side edge connected to the first bottom panel, and corresponding through holes are provided on the first bottom panel for riveting the protrusions on the first side panel and the fourth side panel respectively, so as to achieve the connection stability between the second side panel and the first bottom panel and the connection stability between the fourth side panel and the first bottom panel.

[0011] Furthermore, the first bottom plate is divided by a U-shaped dividing line to form at least two flip plates spaced apart along the length direction of the first pressure plate, and the first folding structure also includes a third folding line corresponding to the two ends of the U-row dividing line, and each of the flip plates is bent vertically upward through the third folding line and its width is adapted to the width of the second side panel and the fourth side panel; two first sockets are provided on the side of each flip plate away from the third folding line at positions corresponding to the second side panel and the fourth side panel, and second sockets are provided on the second side panel and the fourth side panel to cross the first sockets, so as to increase the stiffness stability between the left side panel and the right side panel after the left side panel and the right side panel are formed.

[0012] Furthermore, the second limiting structure includes a second contoured opening formed on the first mating surface of the second limiting portion to adapt to the other end of the seat cushion branch pipe, and a third contoured opening formed on the second mating surface of the second limiting portion for the seat cushion branch pipe to pass through laterally. The second contoured opening is open upward, and the third contoured opening is open toward the side of the first limiting portion opposite thereto and is connected to the second contoured opening, so that the seat cushion branch pipe can be installed on the second limiting portion in a vertical direction.

[0013] The foldable seat frame is constructed so that when the foldable seat frame is in the upright position, the sliding seat can be easily broken, and the sliding seat can be easily broken.

[0014] Furthermore, the second contoured opening extends from one end close to the sixth side panel to the fourth folding line between the third top panel and the sixth side panel, and a limiting plate is formed on the side of the third contoured opening close to the second contoured opening along a transverse extension to block the top of the third contoured opening. The second folding structure also includes a fifth folding line formed vertically between the limiting plate and the sixth side panel. The fifth folding line enables the limiting plate to swing inward and outward relative to the second limiting portion in a transverse direction to open and close the second contoured opening and the third contoured opening, so that the seat cushion branch pipe can vertically penetrate the second contoured opening and the second contoured opening and block the top of the seat cushion branch pipe after its installation is completed, thereby limiting the seat cushion branch pipe from jumping up and down.

[0015] The vehicle seat cushion branch tube packaging structure of the present invention has at least the following beneficial effects: through the cooperation between the supporting cover part and the limiting unit, the movement of the seat cushion branch tube is supported and restricted during packaging, and through the cooperation between the first limiting structure and the second limiting structure, after one end of the seat cushion branch tube is horizontally passed through the first limiting structure, the other end can be vertically passed through the second limiting structure, so as to simplify the installation difficulty of the seat cushion branch tube. At the same time, the second limiting structure can vertically restrict the seat cushion branch tube after the seat cushion branch tube is installed, so that the first limiting structure and the second limiting structure can both restrict the shaking or jumping of the seat cushion branch tube in the horizontal direction and the vertical direction, thereby improving the packaging safety and reliability of the seat cushion branch tube.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figures 1 to 5As shown, the vehicle seat cushion branch tube packaging structure of the present invention includes a cover supporting portion 1 and a limiting unit arranged on the cover supporting portion 1. The cover supporting portion 1 is used to support the bottom of the packaging box, so that when packaging the seat cushion branch tube, it cooperates with other packaging parts to complete the packaging through the packing rope, thereby packaging the seat cushion branch tube inside it to prevent the bottom of the seat cushion branch tube from contacting the ground.

[0029] like Figure 3As shown, in this embodiment, the cover portion 1 includes a bottom support plate 11 and a third folding structure 12 formed on the bottom support plate 11. The bottom support plate 11 is made of, but not limited to, corrugated paper. The bottom support plate 11 has a square sheet-like structure and can be square or rectangular as needed. The third folding structure 12 includes two third fold lines 121 and two fourth fold lines 122 formed on the bottom support plate 11. The two third fold lines 121 are parallel to two opposing sides of the bottom support plate 11. The two third fold lines 121 are mirrored from the center of the bottom support plate 11 on both sides of the bottom support plate 11 near the side edges, thereby sequentially dividing the bottom support plate 11 into a first enclosure 111, a bottom support plate 112, and a second enclosure 113. The first enclosure 111 and the second enclosure 113 are respectively disposed on either side of the bottom support plate 112. The third fold lines 121 are located between the first enclosure 111 and the bottom support plate 112, and between the second enclosure 113 and the bottom support plate 112. The two fourth folding lines 122 are parallel to the other two opposite sides of the bottom support plate 11, so that the fourth folding lines 122 are perpendicular to the third folding line 121. The two fourth 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 bottom support 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 bottom support plate 112. The fourth folding lines 122 are located between the third enclosure 114 and the bottom support plate 112 and between the fourth enclosure 115 and the bottom support plate 112. The third folding line 122 is located between the third enclosure 114 and the bottom support plate 112 and between the fourth enclosure 115 and the bottom support plate 112. 1 and the fourth 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 define each intersecting portion as an end panel 116, and the end panel 116 is connected to the first enclosure 111 or the second enclosure 113, and the end panel 116 is disconnected from the adjacent third enclosure 114 or the fourth enclosure 115 by segmentation. 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 116 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. The folded arrangement forms the bottom support plate 11. The limiting unit is supported by the bottom support plate 112 and is located within the cavity of the bottom support plate 11. To ensure an aesthetically pleasing appearance of the bottom support plate 11, the first, second, third, and fourth panels 114, 115 are all of the same width. Handle holes 117 are symmetrically provided on two of the enclosures, such as the first enclosure 111 and the second enclosure 113, and also on the third enclosure 114 and the third enclosure 114, so that the transporters can increase the gripping force between the packaging structure and their hands through the handle holes 117, thereby facilitating the transporters to move the packaging base.It should be noted that, in this embodiment, the transverse direction refers to the length and width direction of the first limiting portion 2 , and the vertical direction refers to the height direction of the first limiting portion 2 .

[0030] In this embodiment, the limiting unit includes a first limiting portion 2 and a second limiting portion 3 which are arranged on the cover portion 1 and are spaced apart and parallel to each other. The first limiting portion 2 and the second limiting portion 3 both have a first mating surface 4a located at the top and a second mating surface 4b adjacent to the first mating surface 4a. When the first limiting portion 2 and the second limiting portion 3 are installed on the bottom support plate 112, the two second mating surfaces 4b are arranged facing each other. The first limiting portion 2 and the second limiting portion 3 are respectively used to support and fix the two ends of the seat cushion branch pipe to protect the seat cushion branch pipe.

[0031] like Figure 4 As shown, in the content defined in this embodiment, the first limiting portion 2 includes a first pressing plate 21, a first folding structure 22 formed on the first pressing plate 21 to fold the first pressing plate 21 into a square, and a first limiting structure 23 arranged on the first pressing plate 21. The first pressing plate 21 is folded from a sheet structure to a square structure through the first folding structure 22. The first limiting structure 23 is used for allowing one end of the seat cushion branch tube to pass through the folded first pressing plate 21 laterally to limit the movement of the seat cushion branch tube in the horizontal and vertical directions, ensuring that the seat cushion branch tube will not shake laterally or jump vertically during transportation, avoiding collisions of the seat cushion branch tube, and ensuring the packaging reliability and integrity of the seat cushion branch tube.

[0032] In this embodiment, the first pressing plate 21 is a rectangular sheet structure, and the length of the first pressing plate 21 is the same as the length of the bottom supporting plate 112, so that when the first pressing plate 21 forms a three-dimensional structure through the first folding structure 22, the two ends can respectively rest against the first enclosure 111 and the second enclosure 113, and the first enclosure 111, the second enclosure 113 and the first pressing plate 21 support each other to improve the strength and supporting force of the entire packaging structure as a whole, thereby improving durability.

[0033] In this embodiment, the first folding structure 22 includes three first folding lines 221 and three second folding lines 222 spaced apart along the width of the first pressing plate 21. The lengths of the three first folding lines 221 and the three second folding lines 222 are aligned with the length of the first pressing plate 21. The three first folding lines 221 and the three second folding lines 222 are considered a group, and the two groups of first folding lines 221 and second folding lines 222 are mirror-imaged on the first pressing plate 21. The ends of each first folding line 221 and each second folding line 222 extend away from each other to opposite sides of the first pressing plate 21. In the content defined in this embodiment, the three first folding lines 221 and the three second folding lines 222 separate the first pressure plate 21 into the second side plate 211, the first top plate 212, the first side plate 213, the first bottom plate 214, the third side plate 215, the second top plate 216 and the fourth side plate 217, which are connected in sequence. The three first folding lines 221 and the three second folding lines 222 are symmetrically arranged on both sides of the first bottom plate 214. The width of the first bottom plate 214 is much larger than the width of the first side plate 213, the second side plate 211, the first top plate 212, the third side plate 215, the second top plate 216 and the fourth side plate 217. Among them, the first side panel 213 is bent vertically upward along the first folding line 221 between the first bottom panel 214, the first top panel 212 is bent horizontally along the first folding line 221 between the first side panel 213 toward the same side as the first bottom panel 214 (and along the width direction of the first pressure plate 21 toward the third side panel 215), and the second side panel 211 is bent vertically downward along the first folding line 221 between the first top panel 212 and connected to the first bottom panel 214 to form a square tube-shaped left side portion, and the left side portion is arranged on the left side edge of the first bottom panel 214. The third side panel 215 is bent vertically upward along a second fold line 222 between the third side panel 215 and the first bottom panel 214. The second top panel 216 is bent transversely along the second fold line 222 between the third side panel 215 and the third side panel 215 toward the same side as the first bottom panel 214 (i.e., the second top panel 216 is bent toward the first side panel 213 along the width direction of the first pressing plate 21). The fourth side panel 217 is bent vertically downward along the first fold line 221 between the third side panel 215 and the second top panel 216 and connected to the first bottom panel 214 to form a square tubular right side portion. The right side portion is disposed on the right side of the first bottom panel 214. In this manner, the left and right sides strengthen the load-bearing capacity of the packaging structure while improving stability. Furthermore, one first limiting portion 2 can simultaneously cooperate with two second limiting portions 3. Alternatively, different limiting structures can be provided on the left and right sides to accommodate packaging of two products. This increases the width of the packaging structure and the contact area between the first limiting portion 2 and the cover portion 1, thereby improving stability.The first top plate 212 and the second top plate 216 are both defined as the first mating surface 4a, and the first side plate 213 and the third side plate 215 are both defined as the second mating surface 4b so that after folding to form the left and right sides, the first side plate 213 and the third side plate 215 are distributed back to back on the outermost sides of the first limiting portion 2. Correspondingly, one first limiting portion 2 is correspondingly provided with two second limiting portions 3, and the two second limiting portions 3 are arranged on both sides of the first limiting portion 2 along the width direction of the bottom supporting plate 112. The interval between the first limiting portion 2 and the second limiting portion 3 should be adapted to the length of the seat cushion branch pipe so that the two ends of the seat cushion branch pipe can be close to the first limiting portion 2 and the second limiting portion 3. Among them, the width of the first side panel 213 and the third side panel 215 are the same, the width of the second side panel 211 and the fourth side panel 217 are the same, and the width of the first top panel 212 and the second top panel 216 are the same. Since the first pressing plate 21 is made of corrugated paper and has a certain thickness, the width of the second side panel 211 and the fourth side panel 217 can be smaller than the thickness of the first pressing plate 21 relative to the first side panel 213 to ensure the squareness of the first limiting portion 2. The thickness factor of the first pressing plate 21 can also be ignored without affecting the use effect. The present utility model is not limited to the structure of this embodiment. The first folding structure 22 may also include only four first folding lines 221. The four first folding lines 221 sequentially separate the first pressing plate 21 into an eighth side panel, a fourth top panel, a ninth side panel, a third bottom panel and a tenth side panel. The eighth side panel and the ninth side panel are bent downward in the vertical direction, the third bottom panel is bent laterally toward the eighth side panel, and the tenth side panel is bent upward in the vertical direction and overlaps with the eighth side panel to form a square structure, which can also be used to support the seat cushion branch pipe.

[0034] In this embodiment, in order to facilitate the connection between the second side panel 211 and the fourth side panel 217 and the first bottom panel 214, a protrusion 2181 is provided on one side of the second side panel 211 and the fourth side panel 217 connected to the first bottom panel 214, and a through-hole 2182 is provided on each side of the two long sides of the first bottom panel 214 at a width position of the first top panel 212 spaced apart from the long sides in the width direction. The through-hole 2182 is provided in two groups and corresponds to the protrusions on the second side panel 211 and the fourth side panel 217. Block 2181, each group of perforations 2182 are arranged at intervals along the length direction of the first pressure plate 21, and the number of protrusions 2181 on the second side plate 211 and the fourth side plate 217 is the same as the number of perforations 2182. After folding the first pressure plate 21, the protrusions 2181 on the second side plate 211 and the fourth side plate 217 are riveted and penetrated into each perforation 2182 respectively. The width of the protrusion 2181 is consistent with the thickness of the first pressure plate 21 to increase the connection stability between the second side plate 211 and the fourth side plate 217 and the first bottom plate 214. In order to prevent the protrusions 2181 on the second side panel 211 and the fourth side panel 217 from easily detaching from the perforations 2182, the first bottom panel 214 is divided by a U-shaped dividing line to form at least two flip sheets 2191 spaced apart along the length direction of the first pressure plate 21. The first folding structure 22 also includes a third folding line 2192 corresponding to the two ends of the U-row dividing line, so that one side of the flip sheet 2191 is connected to the first pressure plate 21 and the other three sides are not connected to the first pressure plate 21. Each flip sheet 2191 is bent vertically upward along the third folding line 2192 and its width is adapted to the width of the second side panel 211 and the fourth side panel 217, so that the heights of the left side, right side and flip sheet 2191 are consistent to maintain neatness. The flip sheet 2191 extends along the width direction of the first pressure plate 21 on both sides thereof toward the difference and extension between the first folding line 221 and the perforation 2182 on both sides of the first bottom plate 214, so that after the first pressure plate 21 is folded, the second side plate 211 and the fourth side plate 217 both cross the flip sheet 2191. Two first sockets 2193 are provided on the side of each flip piece 2191 away from the third folding line 2192 at positions corresponding to the second side panel 211 and the fourth side panel 217, and second sockets 2194 are provided on the second side panel 211 and the fourth side panel 217, which are cross-inserted with the first sockets 2193, so that when the first pressure plate 21 is folded through the folding structure, the second sockets 2194 on the second side panel 211 and the fourth side panel 217 are respectively inserted into and cross-connected with the first sockets 2193 on each flip piece 2191, and the sum of the lengths of the first sockets 2193 and the second sockets 2194 is equal to the width of the flip piece 2191, so that the protrusion 2181 can be inserted into the through hole 2182.

[0035] In this embodiment, the first limiting structure 23 is formed on the first matching surface 4 a of the first limiting portion 2 , so that the end of the seat cushion branch pipe can pass through the folded first pressing plate 21 . The first retaining structure 23 includes a first contoured opening 231, formed on the second mating surface 4b of the first retaining portion 2, adapted to fit one end of the seat support tube. The first contoured opening 231 is formed on the first side panel 213 and the third side panel 215, and is open toward the opposite side of the second retaining portion 3. The first top panel 212, the second top panel 216, and the first bottom panel 214 seal the top and bottom of the first contoured opening 231. Once the seat support tube is inserted into the first contoured opening 231, the sides of the first contoured opening 231 restrict the seat support tube's freedom in the vertical and lateral directions (primarily along the length of the first pressure plate 21). The coordination between the first and second retaining portions 2 and 3 limits the seat support tube's freedom of movement along the width of the first pressure plate 21, achieving all-around positioning. The first contoured opening 231 is a square hole structure, its width slightly larger than the end dimension of the seat support tube.

[0036] like Figure 5 As shown, in this embodiment, the second limiting portion 3 includes a second pressing plate 31 with a rectangular sheet structure, a second folding structure 32 formed on the second pressing plate 31 to fold the second pressing plate 31 into a square, and a second limiting structure 33 arranged on the second pressing plate 31. The second pressing plate 31 is folded from a sheet structure to form a square structure through the second folding structure 32. The second limiting structure 33 is used for allowing one end of the seat cushion branch tube to pass through the folded second pressing plate 31 laterally to limit the movement of the seat cushion branch tube in the horizontal and vertical directions, ensuring that the seat cushion branch tube will not shake laterally or jump vertically during transportation, avoiding collisions of the seat cushion branch tube, and ensuring the packaging reliability and integrity of the seat cushion branch tube.

[0037] In this embodiment, the length of the second pressure plate 31 is the same as the length of the bottom support plate 112, so that when the second pressure plate 31 forms a three-dimensional structure through the second folding structure 32, the two ends can respectively abut against the first enclosure 111 and the second enclosure 113, thereby being parallel to the first pressure plate 21. The first enclosure 111, the second enclosure 113 and the second pressure plate 31 support each other to improve the strength and supporting force of the entire packaging structure as a whole, thereby improving durability.

[0038] The second folding structure 32 includes four fourth folding lines 321 and a fifth folding line 322 that are spaced apart in sequence along the width direction of the second pressing plate 31. Both ends of each fourth folding line 321 extend back to the opposite side edges of the second pressing plate 31 so that the length direction of each fourth folding line 321 is set along the length direction of the second pressing plate 31. The four fourth folding lines 321 sequentially divide the second pressing plate 31 into a fifth side panel 311, a third top panel 312, a sixth side panel 313, a second bottom panel 314 and a seventh side panel 315. The fifth side panel 311 and the sixth side panel 313 are vertically bent downward along the two fourth folding lines 321 on both sides of the third top panel 312, the second bottom panel 314 is horizontally bent along the fourth folding line 321 between the sixth side panel 313 toward the same side as the third top panel 312, and the seventh side panel 315 is bent upward along the fourth folding line 321 between the second bottom panel 314 to form a square tube shape. Preferably, the widths of the fifth and sixth side panels 311, 313 are consistent with those of the first side panel 213, ensuring that the heights of the first and second stopper portions 2, 3 are consistent, thereby facilitating stacking and packaging. The third top panel 312 is defined as a first mating surface 4a, and the seventh side panel 315 is defined as a second mating surface 4b. The second stopper structure 33 is formed on the first and second mating surfaces 4a, 4b of the second stopper portion 3, enabling the end of the seat support tube to be vertically mounted on the second stopper structure 33.

[0039] In this embodiment, the second retaining structure 33 includes a second contoured opening 331 formed on the first mating surface 4a of the second retaining portion 3 to fit the other end of the seat support tube, and a third contoured opening 332 formed on the second mating surface 4b of the second retaining portion 3 to allow the seat support tube to pass transversely. The second contoured opening 331 is formed on the third top panel 312 and opens upward, while the second contoured opening 331 is formed on the sixth side panel 313 and opens toward the opposite side of the first retaining portion 2. The second contoured opening 331 is adapted to the shape of the end of the seat support tube and is inclined relative to the third top panel 312. The second contoured opening 331 extends from one end of the sixth side panel 313 to the fourth fold line 321 between the third top panel 312 and the sixth side panel 313, and is vertically aligned with the third contoured opening 332. The third contoured opening 332 extends vertically upward near one side of the third top plate 312 to connect with the second contoured opening 331. At this time, the seat cushion branch pipe can vertically penetrate into the first pressure plate 21 from the second contoured opening 331 and the third contoured opening 332 in sequence. The third contoured opening 332 limits the freedom of the seat cushion branch pipe in the length direction of the second pressure plate 31. When the jack is in the folded state, the upper handle 332 is tightened, and the lower handle 333 is tightened to the push-pull mechanism 314, so that the jack is tightened.

[0040] It should be noted that the cover portion 1 and the limiting unit in the present invention are both made of corrugated paper to ensure low cost and recyclability to protect the environment, wherein the first bottom plate 214 and the second bottom plate 314 are connected facing the bottom support plate 112 during installation.

[0041] The working method of one embodiment of the vehicle seat cushion branch pipe packaging structure of the present invention is as follows: before use, the cover portion 1, the first limiting portion 2 and the second limiting portion 3 are folded and formed respectively by the first folding structure 22, the second folding structure 32 and the third folding structure 12, so that the sixth side plate 313 of the second limiting portion 3 is connected to the third surrounding plate 114 and the fourth surrounding plate 115 of the cover portion 1, and the second bottom plate 314 is connected to the bottom supporting plate 112, and the two ends of the second limiting portion 3 are respectively connected to the first surrounding plate 111 and the second surrounding plate Plate 113, so that the second side plate 211 and the fourth side plate 217 of the first limiting part 2 face the sixth side plate 313 respectively, so that the two ends of the first limiting part 2 are respectively connected to the first enclosing plate 111 and the second enclosing plate 113 and are located between the two second limiting parts 3; after the assembly is completed, one end of the seat cushion branch pipe is inserted into the first contour opening 231 horizontally, and the other end of the seat cushion branch pipe is inserted into the third contour opening 332 vertically from the second contour opening 331 until the limiting plate 333 blocks the seat cushion branch pipe, thereby realizing all-round limiting of both ends of the seat cushion branch pipe.
