Description

Technical Field

[0001] This utility model relates to the field of containers, and more specifically to corner post devices and containers. Background Art

[0002] With the continuous development of world trade, the application and transportation of oversized cargo have become more widespread. Containers, due to their versatility, interchangeability, safety, and economy, have become the fastest mode of modern transportation. The maximum height of a standard container is only 2896mm, which cannot meet the needs of transporting oversized cargo. Meanwhile, fixed-height oversized containers are taller than standard containers, resulting in higher transportation costs for ordinary goods. Therefore, some collapsible or flat rack containers have height-adjustable corner posts. However, currently, adjusting the corner post height requires using spreader equipment, which is complex.

[0003] Therefore, this utility model provides a corner post device and a container to at least partially solve the above-mentioned problems. Utility Model Content

[0037] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0038] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0039] In this document, ordinal numbers such as “first” and “second” used in this invention are merely identifiers and do not have any other meaning, such as a specific order.

[0040] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0041] First Implementation Method

[0042] This invention provides a corner post device. The corner post device can be used in a container. The container can be a collapsible container. The container includes a base frame and end frames. The end frames are connected to the ends of the base frame. The corner post device can be used for the end frames. The end frames of the collapsible container are rotatably connected to the base frame between an upright position and a stacked position. When the end frames are in the upright position, the length direction of the corner post device is parallel to the vertical direction. When the end frames are in the stacked position, the end frames are stacked on the base frame.

[0043] The length of the corner post assembly is adjustable. This allows for adjustment of the end frame height (the dimension of the end frame along the length of the corner post assembly). Consequently, the folding box can meet the transportation needs of oversized cargo, and its transportation costs are low.

[0044] Please refer to Figures 1 to 3 The corner post assembly includes a first corner post 110. In the folding case, the bottom end of the first corner post 110 is rotatably connected to the end of the base frame so that the end frame can rotate between an upright position and a stacked position.

[0045] like Figures 1 to 3As shown, the corner post device also includes a steering part 120 and a second corner post 130. A corner piece is provided at the top of the second corner post 130. The steering part 120 can be a columnar structure with its axial direction parallel to the horizontal direction. For example, the axial direction of the steering part 120 is parallel to the width direction of the base frame. The steering part 120 is disposed on the first corner post 110. The second corner post 130 is movably inserted through the first corner post 110 along its length. Thus, the second corner post 130 can move between an extended position and a retracted position. When the second corner post 130 is in the retracted position, the dimension of the corner post device along the length direction of the first corner post 110 is the retracted dimension. When the second corner post 130 is in the extended position, the dimension of the corner post device along the length direction of the first corner post 110 is the extended dimension. The extended dimension is greater than the retracted dimension. Thus, by moving the second corner post 130 along the length direction of the first corner post 110, the corner post device can be extended or retracted, allowing the folding box to meet the transportation needs of oversized cargo, and the transportation cost of the folding box is low.

[0046] like Figure 1 and Figure 2 As shown, the corner post assembly also includes a flexible member 140. The flexible member 140 can be a wire rope or a chain. The flexible member 140 is connected to the second corner post 130. The flexible member 140 extends to the outside of the first corner post 110 and then bypasses the turning portion 120 to extend downwards. The first corner post 110 is provided with an opening 112. The opening 112 can be a hole. The flexible member 140 can pass through the opening 112.

[0047] Thus, releasing or pulling the flexible member 140 drives the second corner post 130 to move between the extended and retracted positions. The flexible member 140 extends downward around the steering portion 120. This facilitates the operation of the flexible member 140.

[0048] It is understood that, in embodiments not shown, the container can be a frame container. The end frames of the frame container are fixedly connected to the underframe. The length direction of the corner post assembly is parallel to the vertical direction. The bottom end of the first corner post 110 is used to connect to the end of the underframe.

[0049] In this embodiment, the second corner post 130 can be moved along the length of the first corner post 110 to extend the corner post device, so that the frame box or folding box can meet the transportation needs of oversized cargo, and the transportation cost of the frame box or folding box is low; the flexible member 140 bypasses the turning part 120 to extend downward, which makes it easy to operate the flexible member 140 to drive the second corner post 130 to move between the extended position and the retracted position, without the need to lift or lower the second corner post 130 with a lifting device, making the operation simple.

[0050] Alternatively, as Figure 2As shown, the corner post assembly also includes a lifting assembly 150 (not shown). The lifting assembly 150 is located outside the first corner post 110. When the corner post assembly is vertically arranged along its length, the lifting assembly 150 is positioned below the turning portion 120. The lifting assembly 150 is connected to the first corner post 110. The lifting assembly 150 includes a rotatable output shaft. The output shaft is wound around the portion of the flexible member 140 located outside the first corner post 110. Thus, rotating the output shaft in one direction winds and tightens the flexible member 140, thereby moving the second corner post 130 toward the extended position. Rotating the output shaft in the other direction releases the flexible member 140, thereby moving the second corner post 130 toward the retracted position. This facilitates the movement of the second corner post 130.

[0051] Optionally, the lifting assembly 150 also includes a torque amplifying component (not shown). The torque amplifying component may include a gear set. The torque amplifying component is connected to the output shaft for driving the output shaft to rotate. Thus, the flexible member 140 can be operated with a smaller force to move the second joist 130.

[0052] Optionally, the lifting assembly 150 further includes a self-locking component (not shown) and an input shaft (not shown). The gear set has an input end and an output end. The input shaft is connected to the input end of the gear set to drive the gear set to rotate. The gear set includes a worm gear and a worm. The worm gear and worm constitute the self-locking component. The worm is connected to the input end of the gear set. The worm gear is connected to the output end of the gear set. The worm meshes with the worm gear. The output end of the gear set is connected to the output shaft. Thus, the input shaft is connected to the output shaft via the self-locking component, allowing the input shaft to drive the output shaft to rotate via the self-locking component. The self-locking component prevents the rotational torque of the output shaft from being transmitted to the input shaft, thereby achieving self-locking. This facilitates the lifting and positioning of the second angle column 130.

[0053] It is understood that, in embodiments not shown, the self-locking component may also take other forms, as long as it is capable of self-locking.

[0054] Optionally, the lifting assembly 150 may include a winch. The winch includes the aforementioned input shaft, output shaft, torque-increasing component, and self-locking component. The winch can be an existing winch, which will not be described in detail here. This facilitates the selection of the lifting assembly 150.

[0055] Alternatively, as Figure 3 As shown, the corner post assembly is connected to the base frame. With the length direction of the corner post assembly parallel to the vertical direction, the lifting assembly 150 is located on the inner side of the first corner post 110 near the center of the base frame along the length direction of the base frame. This protects the lifting assembly 150.

[0056] Optionally, the corner post assembly further includes a guide member (not shown). The guide member is connected to the first corner post 110 and the second corner post 130 to guide the movement of the second corner post 130. Specifically, the guide member may include a guide wheel. The guide wheel is rotatably connected to one of the first corner post 110 and the second corner post 130, with its outer peripheral surface conforming to the other of the first corner post 110 and the second corner post 130. In this way, the guide wheel can roll on the other, thereby guiding the movement of the second corner post 130. Consequently, the movement of the second corner post 130 is smooth.

[0057] It is understood that, in the embodiment not shown, the guide member includes a guide rail and a slider. The length direction of the guide rail is parallel to the length direction of the first corner post. The guide rail is connected to one of the first and second corner posts, and the slider is connected to the other of the first and second corner posts. The guide rail and the slider cooperate to guide the movement of the second corner post.

[0058] Alternatively, as Figure 1 and Figure 2 As shown, the second corner post 130 includes a second body 131. An extension rod 132 is provided at the lower end of the second body 131. The extension rod 132 extends along the length direction of the first corner post 110. The radial dimension of the extension rod 132 is smaller than the radial dimension of the second body 131. A flexible member 140 is connected to the lower end of the extension rod 132. When the length direction of the corner post assembly is parallel to the vertical direction, the lower end of the extension rod 132 is positioned below the position of the turning portion 120. The flexible member 140 extends obliquely upward through the opening 112, then extends obliquely downward from above the turning portion (described later) to the output shaft of the winch, and then wraps around the output shaft.

[0059] The radial dimension of the extension rod 132 is its dimension in the radial direction. The radial direction of the extension rod 132 is perpendicular to its length direction. The radial dimension of the second body 131 is its dimension in the radial direction. The radial direction of the second body 131 is perpendicular to its length direction. Therefore, the length of the second corner post 130 can be reduced, thereby reducing its weight.

[0060] Optionally, the corner post assembly also includes a steering element. The steering element can be a steering wheel. The steering element is rotatably fitted onto the steering portion 120. The flexible element 140 passes around the outer peripheral surface of the steering element. Thus, the movement of the flexible element 140 is smooth.

[0061] Alternatively, as Figure 1 and Figure 2As shown, the first corner post 110 has a first locking hole 114. The second corner post 130 has a second locking hole 133. The corner post assembly also includes a pin 160. The pin 160 is used to pass through the first locking hole 114 and the second locking hole 133 to lock the second corner post 130 to the first corner post 110. At this time, the pin 160 penetrates both the first corner post 110 and the second corner post 130.

[0062] When the second corner post 130 is in the extended position, the latch 160 can pass through the first locking hole 114 and the second locking hole 133 corresponding to the extended position to lock the second corner post 130 in the extended position. When the second corner post 130 is in the retracted position, the latch 160 can pass through the first locking hole 114 and the second locking hole 133 corresponding to the retracted position to lock the second corner post 130 in the retracted position. When the second corner post 130 is in a position between the retracted position and the extended position, the latch 160 can pass through the first locking hole 114 and the second locking hole 133 corresponding to that position to lock the second corner post 130 in that position.

[0063] Furthermore, such as Figure 3 As shown, when the corner post device is connected to the base frame, the axial direction of the first locking hole 114 can be parallel to the width direction of the base frame. Therefore, the pin 160 can be operated from the side of the base frame, making operation of the pin 160 convenient.

[0064] like Figure 1 and Figure 2 As shown, the first corner post 110 has a first body 113. A steering portion 120 is connected to the first body 113. The minimum distance between the bottom ends of the steering portion 120 and the first body 113 along the length direction of the first corner post 110 is the guide distance. The distance that the second corner post 130 moves between the extended position and the retracted position is the moving distance. The guide distance is greater than or equal to the moving distance. Therefore, it is easier to move the second corner post 130.

[0065] like Figure 1 As shown, the corner post device also includes a fixing member 170. The fixing member 170 can be a sheet metal part. The fixing member 170 is located on the outside of the first body 113. The fixing member 170 is fixedly connected to the first body 113. The fixing member 170 is disposed at the first locking hole 114. A pin 160 is movably inserted through the fixing member 170 in a horizontal direction. Thus, the fixing member 170 and the first body 113 together support the pin 160. The connection between the pin 160 and the first body 113 is secure.

[0066] Second Implementation Method

[0067] like Figure 4As shown, the lifting assembly includes a chain hoist. The chain hoist can be any existing chain hoist, and will not be described in detail here. The chain hoist has a steering section 220. In this case, the corner post assembly does not include a steering element. A flexible member extending from the first corner post passes through the chain hoist. In this case, the flexible member bypasses the steering section. Therefore, the corner post assembly has a simple structure.

[0068] Optionally, the chain hoist may include the self-locking component of the first embodiment. This facilitates the lifting and positioning of the second corner post.

[0069] Optionally, after the flexible member extends obliquely upward through the opening, it passes over the turning part 220 from above and then extends obliquely downward.

[0070] The other settings of the second embodiment are largely the same as those of the first embodiment, and will not be described in detail here.

[0071] This utility model also provides a container. The container includes the aforementioned corner post device. The container can be constructed as a collapsible container or a frame container.

[0072] In this embodiment, the container includes the aforementioned corner post device, which allows the second corner post 130 to move along the length of the first corner post 110, thereby extending the corner post device. This enables the frame container or folding container to meet the transportation needs of oversized cargo, and the transportation cost of the frame container or folding container is low. The flexible member 140 bypasses the turning part 120 and extends downward, which facilitates the operation of the flexible member 140 to drive the second corner post 130 to move between the extended position and the retracted position. There is no need to lift or lower the second corner post 130 using a spreader, making the operation simple.

However, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit the utility model to the described embodiments.
