[0048] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.
[0049] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.
[0050] In this document, ordinal numbers such as “first” and “second” cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order.
[0051] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.
[0052] The utility model provides an external hinge. The external hinge is used for a hinge device. The hinge device is used for a platform-type container. The platform-type container comprises a base frame and an end frame. The end frame is rotatably connected to the base frame through the hinge device. In this way, the end frame can be rotated between an upright position extending along a vertical direction D3 and a stacked position extending along a horizontal direction and stacked on the base frame.
[0053] Please refer to Figures 1 to 5 , the external hinge is used to connect to the base frame. The following description is made by taking the hinge device arranged on the base frame as an example. When the hinge device is arranged on the base frame, the first horizontal direction D1 is parallel to the width direction of the base frame. The second horizontal direction D2 is parallel to the length direction of the base frame. The first horizontal direction D1 is perpendicular to the second horizontal direction D2.
[0054] like Figures 1 to 5 As shown, the external hinge includes a wall panel 110. The plane where the wall panel 110 is located is perpendicular to the first horizontal direction D1. The wall panel 110 includes an outer wall panel 111 and an inner wall panel 112. The outer wall panel 111 and the inner wall panel 112 are arranged at intervals along the first horizontal direction D1.
[0055] like Figures 1 to 3 As shown, the external hinge also includes a connecting member 120. The connecting member 120 includes an upper angle plate 121. The plane where the upper angle plate 121 is located is perpendicular to the vertical direction D3. The upper angle plate 121 is connected to the top end of the exterior wall plate 111 and the top end of the interior wall plate 112. The end surface of the upper angle plate 121 close to the center of the base frame along the second horizontal direction D2 is an inner end surface 130. The inner end surface 130 is recessed away from the center of the base frame along the second horizontal direction D2 to form a notch 125. The notch 125 has a bottom surface 126. The bottom surface 126 is perpendicular to the second horizontal direction D2.
[0056] like Figure 5 and Figure 6 As shown, when the end frames of the platform-type container provided with a hinge device are in a stacked state, the lock head 180 of the twist lock of the prior art can be extended through the notch 125 to between the outer wall panel 111 and the inner wall panel 112, and then the lock head 180 can be rotated to lock the twist lock to the connecting member 120.
[0057] Please refer to Figures 1 to 5 , the outer hinge further includes a stopper 140. The stopper 140 is connected to the upper corner plate 121 and the wall plate 110. It can be understood that in an embodiment not shown, the stopper can be connected to the upper corner plate or the wall plate.
[0058] The blocking member 140 is located between the outer wall panel 111 and the inner wall panel 112. The blocking member 140 is located below the upper corner panel 121. Along the second horizontal direction D2, the blocking member 140 is located on the inner side of the bottom surface 126 close to the center of the bottom frame, and the blocking member 140 and the bottom surface 126 are spaced apart. When the locking head 180 is located between the outer wall panel 111 and the inner wall panel 112, the locking head 180 is located between the blocking member 140 and the side panel 129 described later. In this way, the blocking member 140 and the connecting member 120 can block the locking head 180 from moving along the second horizontal direction D2, thereby leaving the outer hinge through the notch 125.
[0059] In this embodiment, the blocking member 140 can block the twist lock that locks the connecting member 120 from leaving the connecting member 120, so as to ensure the safety of transporting a plurality of stacked step-type containers.
[0060] Alternatively, if Figure 2 As shown, along the second horizontal direction D2, the end surface of the upper angle plate 121 away from the inner end surface 130 is the outer end surface 128. Along the second horizontal direction D2, the minimum distance a between the outer end surface 128 and the blocking member 140 is in the range of a≥151.5 mm. Thus, the twist lock can be blocked more effectively.
[0061] Optionally, refer to Figure 1 and Figure 3 , the blocking member 140 includes an outer blocking member 141 and an inner blocking member 142. The outer blocking member 141 and the inner blocking member 142 are spaced apart along the first horizontal direction D1. The outer blocking member 141 is located on the side of the inner blocking member 142 close to the outer wall panel 111. The outer blocking member 141 is connected to the outer wall panel 111. The inner blocking member 142 is connected to the inner wall panel 112. The inner hinge 160 described below is located between the outer blocking member 141 and the inner blocking member 142. Along the first horizontal direction D1, the minimum dimension b between the outer blocking member 141 and the inner blocking member 142 is in the range of b<100mm. Thus, the twist lock can be blocked more effectively.
[0062] like Figure 1As shown, the notch 125 has an inner side surface 127. The blocking member 140 is located on the outer side of the inner side surface 127 away from the center of the notch 125 along the first horizontal direction D1. Specifically, the connecting member 120 includes two side arms 122 and a bottom arm 124. The bottom arm 124 has an outer end surface 128 of the upper angle plate 121 and a bottom surface 126 of the notch 125. Both side arms 122 extend along the second horizontal direction D2. The bottom arm 124 is located on the outer side of the side arm 122 away from the center of the chassis along the second horizontal direction D2. The bottom arm 124 is connected to the side arm 122. In this way, the two side arms 122 and the bottom arm 124 form a U-shaped structure, thereby forming the notch 125. The surface of the bottom arm 124 close to the center of the chassis along the second horizontal direction D2 is the bottom surface 126 of the notch 125. Along the first horizontal direction D1, the surface of the side arm 122 close to the center of the notch 125 is the inner side surface 127 of the notch 125.
[0063] like Figures 1 to 3 As shown, the two side arms 122 include an outer side arm 131 and an inner side arm 132. The outer side arm 131 is connected to the outer stopper 141 and the outer wall panel 111. The inner side arm 132 is connected to the inner stopper 142 and the inner wall panel 112. Along the first horizontal direction D1, the outer stopper 141 is located between the inner side surface 127 of the outer side arm 131 and the outer wall panel 111. Thus, along the first horizontal direction D1, the outer stopper 141 is located outside the inner side surface 127 of the outer side arm 131 away from the center of the notch 125. Along the first horizontal direction D1, the inner stopper 142 is located between the inner side surface 127 of the inner side arm 132 and the inner wall panel 112. Thus, along the first horizontal direction D1, the inner stopper 142 is located outside the inner side surface 127 of the inner side arm 132 away from the center of the notch 125. Therefore, on the basis that the blocking member 140 does not interfere with the inner hinge 160 described later, the structure of the inner hinge 160 described later is simple.
[0064] Optionally, please continue to refer to Figures 1 to 3 , along the second horizontal direction D2, the blocking member 140 is located between the bottom surface 126 and the inner end surface 130. Thus, the blocking member 140 can be prevented from being bumped by other components, thereby protecting the blocking member 140.
[0065] Alternatively, if Figures 1 to 3 As shown, the blocking member 140 includes a first plane 143 and a second plane 144. The first plane 143 and the second plane 144 intersect. The first plane 143 is attached to the wallboard 110. The second plane 144 is attached to the lower surface of the connecting member 120. Thus, the installation of the blocking member 140 is facilitated.
[0066] Furthermore, the blocking member 140 is configured as a rectangular parallelepiped structure, thereby facilitating the selection of the blocking member 140 .
[0067] Furthermore, the length direction of the blocking member 140 is parallel to the vertical direction D3 , thereby being able to more effectively block the locking head 180 of the twist lock.
[0068] like Figures 1 to 3 As shown, the connection member 120 further includes a side plate 129. The side plate 129 is located below the upper angle plate 121 and is connected to the upper angle plate 121. The side plate 129 extends to the lower side of the upper angle plate 121. The side plate 129 is connected to the exterior wall plate 111 and the interior wall plate 112. In this way, the strength of the connection member 120 is large.
[0069] Further preferably, the connecting member 120 is an L-shaped connecting member. Thus, the connecting member 120 has a simple structure.
[0070] Alternatively, if Figure 1 , Figure 4 and Figure 5 As shown, the outer hinge further includes a bottom corner piece 150. The bottom corner piece 150 may be a bottom corner piece of a container in the prior art. The bottom corner piece 150 is connected to the outer wall panel 111 and the inner wall panel 112. Thus, the strength of the outer hinge is large. In addition, the platform-type container can be fixed by the bottom corner piece 150.
[0071] The utility model also provides a hinge device. The hinge device includes the aforementioned outer hinge, an inner hinge 160 and a pin 170. The inner hinge 160 is used to be connected to the aforementioned end frame. The inner hinge 160 is pivotally connected to the outer hinge through the pin 170. The inner hinge 160 is located between the outer blocking member 141 and the inner blocking member 142.
[0072] In this embodiment, the hinge device includes the aforementioned external hinge, and the blocking member 140 can block the twist lock that locks the connecting member 120 from leaving the connecting member 120, so as to ensure the safety of transporting a plurality of stacked step containers.
[0073] The utility model also provides a platform type container. The platform type container comprises the aforementioned hinge device.
[0074] In this embodiment, the platform container includes the aforementioned hinge device, the hinge device includes the aforementioned external hinge, and the blocking member 140 can block the twist lock of the locking connecting member 120 from leaving the connecting member 120, so as to ensure the safety of transporting multiple stacked step containers.
