[0049] In the following description, numerous specific details are set forth to provide a more thorough understanding of this application. However, it will be apparent to those skilled in the art that embodiments of this application 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 to avoid confusion with embodiments of this application.
[0050] The preferred embodiments of this application 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.
[0051] In this document, ordinal numbers such as “first” and “second” used in this application are merely identifiers and do not have any other meaning, such as a specific order.
[0052] To fully understand the embodiments of this application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, other embodiments may be available in addition to these detailed descriptions.
[0053] This application provides a lock. This lock can be used in containers. Please refer to... Figure 1 , Figures 3 to 5 The container includes a body 110 and a door 140. The body 110 includes a base frame, side walls, end walls, and a top wall. The base frame, side walls, end walls, and top wall form a generally rectangular parallelepiped structure. The side walls of the body 110 have openings. The door 140 is pivotally connected to the side wall of the body 110 between an open position and a closed position. Locks are used to lock the door 140 to the body 110 when it is in the closed position.
[0054] Please refer to Figure 2 , Figures 6 to 12 The lock includes a hook 120. The hook 120 includes an extension 121 and a blocking portion 122. The plane containing the extension 121 intersects the plane containing the blocking portion 122. One end of the extension 121 is connected to one end of the blocking portion 122. The end of the extension 121 away from the blocking portion 122 is used to connect to the housing 110. At this time, the plane containing the extension 121 is perpendicular to the height direction of the housing 110. The plane containing the blocking portion 122 is perpendicular to the width direction of the housing 110. When the hook 120 is connected to the housing 110, along the height direction of the housing 110, the blocking portion 122 is located above the extension 121, and along the width direction of the housing 110, there is a first gap between the blocking portion 122 and the bottom side beam 111 of the housing 110.
[0055] like Figure 2 , Figures 6 to 12 As shown, the lock also includes a lock base 130. The lock base 130 and the lock hook 120 correspond one-to-one. The projection of the lock base 130 onto the plane containing the side wall of the container 110 is the lock base projection, and the projection of the lock hook 120 onto the plane containing the side wall of the container 110 is the lock hook projection. When the lock is connected to the container, the lock base projection of the corresponding lock base 130 is separated from the lock hook projection of the lock hook 120. Thus, when the container door 140 is moved to the closed position, the lock base 130 can avoid the lock hook 120.
[0056] Please continue to refer to this. Figure 2 , Figures 6 to 12The lock also includes a locking element 150 and a pin 160. The locking element 150 is pivotally connected to the lock base 130 via the pin 160. Thus, the locking element 150 is movably positioned between a locked position and an unlocked position. When the lock base 130 is connected to the door 140, the axis of the pin 160 is perpendicular to the plane containing the door 140.
[0057] When the lock is connected to the container, the locking member 150 in the locked position can move into the first gap to lock the container door 140 to the container body 110. When the locking member 150 is in the unlocked position, it leaves the first gap. At this time, the container door 140 can rotate toward the open position.
[0058] In this embodiment, the lock includes a lock hook 120, a lock base 130, and a locking member 150. When the lock is connected to the container, and the container door 140 is in the closed position, the locking member 150 is rotated to the locked position to lock the container door 140 to the container body 110. The lock has few parts and a simple structure.
[0059] Preferably, such as Figure 2 As shown, the lock base 130 includes a first vertical portion 131 and a horizontal portion 132. When the lock is connected to the container, the horizontal portion 132 extends along the length of the container body 110. The extension direction of the first vertical portion 131 is perpendicular to the extension direction of the horizontal portion 132. The first vertical portion 131 is connected to the horizontal portion 132. Along the thickness direction of the container door 140, the locking member 150 is located on the side of the first vertical portion 131 away from the container door 140. The locking member 150 is pivotally connected to the first vertical portion 131 via a pin 160. When the locking member 150 is located within a first gap, the horizontal portion 132 is located below the extension 121. In this way, the lock base 130 has high strength. Furthermore, when the container door 140 is in the closed position, the container door 140 can support the extension 121 via the horizontal portion 132, thereby supporting the container body 110 and preventing the bottom beam connected to the lock hook 120 (described later) from bending downwards.
[0060] Please continue to refer to this. Figure 2 The lock base 130 also includes a second vertical portion 133. The second vertical portion 133 is arranged parallel to the first vertical portion 131. Along the extending direction of the first vertical portion 131, the first vertical portion 131 and the second vertical portion 133 are located on the same side of the horizontal portion 132. Along the extending direction of the horizontal portion 132, there is a second gap between the first vertical portion 131 and the second vertical portion 133. The horizontal portion 132 is located within the second gap. The horizontal portion 132 is connected to the second vertical portion 133.
[0061] Along the extending direction of the horizontal portion 132, the second gap is larger than the maximum size of the locking hook 120. Along the extending direction of the horizontal portion 132, the locking hook 120 and the corresponding first vertical portion 131 of the locking seat 130 are spaced apart. Along the extending direction of the horizontal portion 132, the locking hook 120 and the corresponding second vertical portion 133 of the locking seat 130 are spaced apart. Thus, the locking hook 120 can pass through the second gap of the corresponding locking seat 130, so that the extension 121 is located between the first vertical portion 131 and the second vertical portion 133. Therefore, the locking seat 130 has high strength.
[0062] More preferably, the lock base 130 is constructed in a U-shape. Therefore, the lock base 130 has a simple structure.
[0063] The lock also includes a reinforcing member 170. The reinforcing member 170 is used to connect to the bottom side beam 111 of the container 110. When the lock is connected to the container, the reinforcing member 170 is located within a first gap. The lower end of the reinforcing member 170 is located above the extension 121. The width of the reinforcing member 170 is smaller than the width of the locking hook 120. A third gap exists between the reinforcing member 170 and the blocking portion 122. The locking member 150, in the locked position, can move into the third gap. This strengthens the position of the connecting locking hook 120 of the container 110.
[0064] It should be noted that the width dimension of the reinforcing member 170 refers to its length along the container body 110 when the lock is connected to the container. The width dimension of the locking hook 120 refers to its length along the container body 110 when the lock is connected to the container. Therefore, the lock seat 130 does not need to have a structure to avoid the reinforcing member 170, and the structure of the lock seat 130 is simple.
[0065] like Figure 11 and Figure 12 As shown, the width dimension D2 of the locking member 150 is less than or equal to the width dimension D1 of the first vertical part 131. When in the unlocked position, the locking member 150 can rotate to the downward position under its own weight. Figure 12 (Location). The locking member 150, located in the drooping position, extends approximately parallel to the first vertical portion 131. The width dimension D2 of the locking member 150 is set to be less than or equal to the width dimension D1 of the first vertical portion 131 to prevent the locking member 150 from protruding from the first vertical portion 131 along the extension direction of the horizontal portion 132, thereby preventing the locking member 150 from blocking the locking hook 120 from extending into the second interval.
[0066] like Figure 7 and Figure 8 As shown, the free end of the locking member 150 is provided with an operating part 151. Thus, the operating part 151 can be grasped to operate the locking member 150.
[0067] Along the axial direction of the pin 160, the free end of the locking member 150 is bent away from the lock seat 130 to form the operating part 151. Thus, the structure of the locking member 150 is simple.
[0068] It is understood that, in embodiments not shown, the operating part may also be in other forms, such as an operating ring rotatably connected to the free end of the locking member.
[0069] This application also provides a container. The container includes a container body 110, a container door 140, and the aforementioned lock. The container door 140 is pivotally connected to the container body 110.
[0070] In this embodiment, the container includes the aforementioned lock, which includes a lock hook 120, a lock seat 130, and a locking member 150. When the lock is connected to the container, if the container door 140 is in the closed position, the locking member 150 is rotated to the locked position to lock the container door 140 to the container body 110. The lock has few parts and a simple structure.
[0071] like Figures 1 to 6 As shown, the container body 110 has a bottom beam at its bottom end. The bottom beam includes a bottom side beam 111 and a bottom end beam. An extension 121 of the locking hook 120 is connected to the bottom side beam 111 of the container body 110. The container door 140 has a side beam 141. The side beam 141 is located at the end of the container door 140 away from the pivot position of the container door 140. The lock seat 130 is connected to the side beam 141. Thus, the structure of the container is simple.
[0072] Please refer to Figure 6 The minimum distance between the horizontal portion 132 and the side beam 141 connected to the lock seat 130 is greater than the height dimension of the lock hook 120 along the height direction of the housing 110. Therefore, the lock hook 120 can pass through the second gap.
[0073] like Figure 1 , Figures 3 to 5 As shown, the upper end of the container door 140 is pivotally connected to the container body 110. This facilitates the unloading of bulk cargo when the container is used to transport bulk cargo.
[0074] Preferably, please return. Figure 6 The blocking part 122 is located below the upper surface 112 of the bottom beam. Therefore, the door 140 does not need to have a structure to avoid the blocking part 122, and the structure of the door 140 is simple.
[0075] Please return Figure 6 The reinforcing member 170 is located below the upper surface 112 of the bottom beam. Therefore, the door 140 does not need to have a structure to avoid the reinforcing member 170, and the structure of the door 140 is simple.
[0076] With the door 140 in the closed position, the lock seat 130 is located above the lower surface 113 of the bottom beam. This prevents the lock seat 130 from extending beyond the outer contour of the box body 110, facilitating transportation.
[0077] It is understood that, in the embodiment not shown, the door may also be pivotally connected to the end wall of the enclosure. In this case, the locking hook is connected to the bottom end beam.
