  • this structure makes it possible to access the goods from one side of the pallet box, the arrangement of the poles 15 is still inconvenient for the access of the goods; at the same time, the pallet box has only three side walls, which is easy to cause The scattered goods are loaded.
  • the folding mechanism of the tray box is complicated, which is not conducive to the realization of unfolding and folding.
  • One object of the present invention is to provide a folding pallet box that saves storage space for the pallet box itself while facilitating the access of goods when loading goods.
  • Another object of the present invention is to provide a folding method for a folding tray box which can quickly and easily change the tray box from an unfolded state to a folded state to save space when the tray box is transported empty.
  • the present invention provides a folding pallet box including at least a bottom plate; corner posts respectively disposed at four corners of the bottom plate; and side walls including a first side wall and a second side wall respectively disposed at a pair of opposite sides of the bottom plate; a rear wall disposed on one side of the bottom plate and adjacent to the side wall; and a door end disposed on a side of the first side wall , which also includes more a first connecting mechanism for pivoting each of the side wall and the rear wall to the bottom plate respectively; and at least one second connecting mechanism for pivoting the door end to the first side wall on.
  • a bracket is also provided on each of the corner posts for supporting the side wall after the side wall is unfolded.
  • a positioning groove is disposed at a top end of at least one of the corner posts.
  • Each of the side walls includes side pillars respectively located at right and left sides thereof, and a positioning pin is disposed on at least one of the side pillars, corresponding to a position of the positioning groove of the corner pillar, and when the tray box is unfolded, The positioning pin is located in the corresponding positioning slot.
  • a slope is also provided, which guides when the positioning pin enters and exits the positioning groove.
  • Each of the first connecting mechanisms includes a first hinge plate fixed to the bottom plate; a second hinge plate fixed to the side wall or the rear wall; and a pin shaft connected to the first and second hinge plates
  • a side wall or a rear wall connected to the second hinge plate may be pivoted about the pin axis.

  • the hole in the second hinge plate to which the wall is connected is a circular hole.
  • At least one interlocking mechanism is also provided on the rear wall for fixing the rear wall to at least one of the side walls. At least one of the side walls is further provided with a limit block on a side adjacent to the rear wall.
  • the door end is flipped relative to the first side wall by the second connecting mechanism, and the maximum flip angle is at least 270°.
  • the door end also includes at least one interlocking mechanism for securing the door end to the second side wall when closed, thereby forming a closed box structure.
  • the present invention also provides a folding tray box folding method, comprising the following steps: (1) providing a tray box, including a bottom plate; corner posts, respectively disposed at four corners of the bottom plate; a wall, comprising first and second side walls respectively disposed on opposite side edges of the bottom plate; a rear wall disposed on one side of the bottom plate and adjacent to the side wall respectively; and a door The end is disposed on one side of the first side wall; (2) providing a plurality of first connecting mechanisms for pivoting each of the side wall and the rear wall to the bottom plate respectively; (3) Providing at least one second connecting mechanism for pivoting the door end to the first side wall; (4) flipping the door end toward an outer side of the tray box, and the door end is attached to the first side wall And the outer wall; and (5) respectively flipping the rear wall and the two side walls toward the inner side of the tray box, and sequentially placing them on the bottom plate.
  • the method further comprises: arranging a positioning groove at a top end of the at least one corner post; and at least one of the side pillars on the left and right sides of each of the side walls, further providing a positioning pin so that the tray box is at In the unfolded state, the locating pin is located in the locating slot of the corner post.
  • the method also includes disposing at least one interlocking mechanism on the rear wall for attaching the rear wall to the tray box when it is in an unfolded state One less of the side walls is fixed.

下面结合附图和实施例对本发明做进一步详细说明。
图 3示出了本发明的一种折叠式托盘箱 100， 包括底板 110， 分别设置在 底板 110四角的角立柱 120， 分别设置在底板 110相对的两个侧边的两个侧壁 130和 140， 设置在底板 110侧边， 并与两个侧壁 130、 140分别相邻的后壁 150, 以及设置在其中一个侧壁， 例如第一侧壁 130， 的一个侧边上的门端（门 壁） 170， 其中， 侧壁 130、 140以及后壁 150分别通过第一连接机构 160枢接 到底板 110上， 而门端 170通过第二连接机构 171枢接到第一侧壁 130上。
侧壁 130、 140还分别包括设置在其两侧的两个边立柱 131、 141， 在托盘 箱 100处于展开状态 （工作状态） 时， 该边立柱 131、 141分别与角立柱 120 相固定， 从而使侧壁 130、 140与底板 110相固定。在侧壁 130、 140邻近后壁 150的位置上， 分别设有一限位块 192 (如图 8所示） ； 在后壁 150上邻近侧 壁 130、 140的位置上， 分别设有一连锁机构 151。 当托盘箱 100处于展开状 态时， 限位块 192可防止后壁 150过度展开， gp， 限制后壁 150与底板 1 10 的夹角不大于 90度；而连锁机构 151可将后壁 150分别与两侧壁 130相固定， 从而形成稳定的箱体结构。
门端 170可通过第二连接机构 171 (如合页） 相对该第一侧壁 130翻转， 从而可实现托盘箱 100 的打开和关闭， 便于货物的放置和取出。 在门端 170 靠近另一侧壁， 即第二侧壁 140， 的一侧还设有两个连锁机构 172， 用于在门 端 170关闭时将其与第二侧壁 140相固定，从而形成封闭的箱体结构， 防止托 盘箱装载的货物散落。 图 4示出了托盘箱 100装载货物后的情形。
如图 5所示， 角立柱 120包括水平设置的托板 121， 位于该角立柱一侧顶 端的定位槽 122和斜面 123， 以及支撑柱 124， 其中， 托板 121放置在支撑柱 124上， 并且角立柱 120通过支撑柱 124与底板 110相固定。 在侧壁处于展开 状态时，托板 121可通过支撑设置在侧壁上的边立柱来支撑该侧壁。 由于托板 121是放置在支撑柱 124上的， 因而可以保证托板 121在承载侧壁时的强度要 求。
接下来， 结合图 6a〜6c， 以第二侧壁 140及其上的第一连接机构 160为例 说明第一连接机构 160的结构及侧壁的折叠过程。
如图 6a所示，第一连接机构 160包括与底板 110相固定的第一铰链板 161、 与第二侧壁 140相固定的第二铰链板 162、 以及同时贯穿第一铰链板 161和第 二铰链板 162的销轴 163， 其中， 第二铰链板 162可通过销轴 163相对第一铰 链板 161转动。 第二铰链板 162相对的两侧分别设有一孔 165。 根据本发明的 一较佳实施例， 该孔可为长圆孔， 并具有靠近侧壁的第一位置 1651和远离侧 壁的第二位置 1652， 如图 6b所示。 销轴 163的两端分别穿过该长圆孔 165。 另外， 如图 6b所示， 在边立柱 141上对应于角立柱的定位槽 122的位置上， 还设有一定位销 190。
当第二侧壁 140处于工作状态时， 由于重力的作用， 销轴 163位于孔 165 的第一位置 1651， 而定位销 190位于定位槽 122中， 可限制第二侧壁 140的 转动。 当需要折叠侧壁时， 首先将第二侧壁 140向上提起， 如图 6b所示， 这 时， 定位销 190位于定位槽 122上方， 销轴 163位于孔 165的第二位置 1652。 接着， 将侧壁 140以销轴 163为轴， 向托盘箱内侧翻转， 如图 6c所示， 这时， 定位销 190可沿角立柱 120的斜面 123向下滑动，斜面 123对定位销 190起到 了导向作用。最后，将第二侧壁 140翻转至与底板 110平行的位置，完成折叠。 后壁 150的折叠过程较为简单， 首先将连锁机构 151 打开， 使后壁 150 与第一、 第二侧壁 130、 140相分离后， 然后直接朝向托盘箱内侧翻转即可。 需要注意， 根据本发明的一较佳实施例， 与后壁 150相连的第一连接机构 160 的第二铰链板 162上的孔 165为圆形孔，从而可在后壁 150展开后防止其上下 窜动， 保持托盘箱的结构稳固。
对空载的托盘箱 100进行折叠的步骤包括：
步骤 1， 将门端 170朝向托盘箱 100的外侧翻转， 如图 7所示， 使其贴到 第一侧壁 130的外侧， 在这里， 门端 170的翻转角度可至少达到 270° ；
步骤 2， 打开后壁 150上连锁机构 151， 将后壁 150朝向托盘箱 100的内 侧翻转， 如图 8所示， 并放置到底板 110上；
步骤 3，将第一侧壁 130和第二侧壁 140分别略向上提起，使得定位销 190 分别与对应的定位槽 122相分离，并将第一侧壁 130和第二侧壁 140分别朝向 托盘箱 100的内侧翻转， 如图 9所示， 依次叠放到后壁 150上。
折叠状态 （存储状态） 的托盘箱 100如图 10所示。 需要注意， 在这里是 按照后壁 150、侧壁 140和侧壁 130的顺序，依次将它们放置到底板 110上的， 然而根据本发明其它的较佳实施例，也可以按照其它的次序叠放侧壁 130、 140 和后壁 150。
利用本发明的折叠式托盘箱，不仅可以在托盘箱空载运输时方便快捷地将 其从展开状态变为折叠状态（存储状态） ， 以节省托盘箱本身的存放空间， 而 且通过可翻转动门端结构，更使得该托盘箱能在装载货物时打开门端，提供便 于货物存取的空间，同时有效地防止货物散落，从而保证了运输和存储的安全。
应当指出，虽然通过上述实施方式对本发明进行了描述，然而本发明还可 有其它多种实施方式。在不脱离本发明精神和范围的前提下， 熟悉本领域的技 术人员显然可以对本发明做出各种相应的改变和变形，但这些改变和变形都应 当属于本发明所附权利要求及其等效物所保护的范围内。 工业应用性
本发明的托盘箱，不仅便于托盘箱自身的存储和运输，而且便于其中装载 的货物的存取， 从而能够满足托盘箱用户的实际需要。
