[0082] The present application provides a kind of box door device.
[0083] First embodiment
[0084] Please refer to Figure 1 And Figure 2 Box door device 100 is used for container. Specifically, box door device 100 includes box door body 110 and discharge door 120.Box door body 110 has discharge port 111 for communicating with the outside and the inside of container. The top of box door body 110 has first edge 112 close to the inside of container along the thickness direction DT of box door body 110 and second edge 113 away from the inside of container. Discharge door 120 is pivotally connected to box door body 110 between opening position for opening discharge port 111 and closing position for closing discharge port 111. Further, box door device 100 further includes first door lock assembly 130. Please refer to Figures 1 to 4The first door lock assembly 130 includes a cooperating member 131 and a locking member 132. The cooperating member 131 is connected to the discharge door 120 or the container door body 110. The cooperating member 131 has a locking hole with an axis extending along the vertical direction DH. The locking member 132 is arranged along the vertical direction DH and detachably connected to the cooperating member 131 between a plugging position and a separation position along the vertical direction DH. It is to be noted that the locking member 132 in the plugging position is connected to the locking hole so that the discharge door 120 is limited in the closed position; the locking member 132 in the separation position is separated from the cooperating member 131. In the state that the locking member 132 is in the separation position and the first edge 112 is above the second edge 113, the discharge door 120 can be pivoted from the closed position to the open position under the action of gravity to complete the discharge.
[0085] According to the container door device 100, the cooperating member 131 and the locking member 132 can jointly limit the discharge door 120 in the closed position, avoiding the discharge door 120 from being opened during transportation. Moreover, when discharging, even if the worker releases the connection between the cooperating member 131 and the locking member 132, the discharge door 120 will not be opened automatically, ensuring the operation safety of the worker. It is to be noted that the container is overturned so that the first edge 112 is above the second edge 113, and then the discharge door 120 can be pivoted from the closed position to the open position under the action of gravity to complete the discharge.
[0086] Please refer to Figure 1 and Figure 2 Preferably, the discharge port 111 is located at the lower part of the container door body 110. The container door body 110 includes a door frame 114 located at the edge of the discharge port 111. The discharge door 120 is pivotably connected to the door frame 114 about an axis extending along the width direction DW of the container door body 110. A plurality of hinges 116 are arranged between the discharge door 120 and the door frame 114 and are spaced along the width direction DW of the container door body 110. The container door body 110 further includes an upper door plate 115 located above the door frame 114.
[0087] Please continue to refer to Figures 1 to 4The box door device 100 further comprises a second door lock assembly 140. The second door lock assembly 140 is connected to the discharge door 120 and the box door body 110. The second door lock assembly 140 is located below the pivot axis of the discharge door 120 relative to the box door body 110; or in other words, the second door lock assembly 140 is located below the hinge 116. Specifically, the second door lock assembly 140 comprises a lock rod 141, a lock head 142 and a lock seat 143. The lock rod 141 is arranged along the width direction DW of the box door body 110. The lock rod 141 is connected to the discharge door 120. The lock rod 141 is located at the side of the discharge door 120 away from the interior of the container. The number of the lock head 142 is at least one, and the at least one lock head 142 is connected to the lock rod 141. The lock seat 143 is connected to the box door body 110, and in the state that the discharge door 120 is located at the closed position, the lock seat 143 is used for connecting to the lock head 142. Please refer to Figure 4 The lock seat 143 has a receiving cavity 146 for accommodating the lock head 142. The lock seat 143 further has an opening 147 communicating with the outside and the receiving cavity 146, and the size of the opening 147 is smaller than the outer circumferential size of the lock head 142. Further, the lock seat 143 is made of elastic material, and in the state that the locking member 132 is located at the separation position and the first edge 112 is located above the second edge 113, the lock head 142 can extrude the lock seat 143 under the action of gravity, so that the lock seat 143 is elastically deformed to separate from the lock seat 143. In this way, the discharge door 120 can be pivoted to the open position to complete the discharging.
[0088] Please continue to refer to Figure 4 The matching member 131 is connected to the lock seat 143. Preferably, the number of the matching member 131 is two, and the locking member 132 is at least partially configured as a rod-shaped member. For example, the locking member 132 is configured as a pin shaft. The two matching members 131 are spaced along the axial direction of the locking member 132. It can be understood that in order to facilitate the lock head 142 to be embedded into the receiving cavity 146, the spacing of the two matching members 131 along the axial direction of the locking member 132 increases from the inside to the outside of the receiving cavity 146.
[0089] Please refer back to Figure 3, preferably, the number of the lock heads 142 is two and each is connected to one end of the lock bar 141. Along the width direction DW of the box door body 110, both ends of the lock bar 141 protrude outward from the discharge port 111. Further, the second door lock assembly 140 further comprises a bracket 144 and a first limiting member 145. The bracket 144 is connected to the discharge door 120 and located at the outer periphery of the lock bar 141, so that the lock bar 141 is connected to (or fixed to) the discharge door 120. The first limiting member 145 is connected to the lock bar 141 and located at the outer periphery of the lock bar 141. The first limiting member 145 is located at at least one side of the bracket 144 closest to the end of the lock bar 141 along the axial direction of the lock bar 141. Preferably, the first limiting member 145 is a ring-shaped member and is integrally formed with the lock bar 141, and the bracket 144 has a mounting hole suitable for the lock bar 141. It can be understood that in order to avoid the lock bar 141 sliding along the axial direction of the lock bar 141 and deviating from the predetermined mounting position, the outer diameter of the first limiting member 145 is larger than the size of the mounting hole. Figure 3 In this embodiment, the number of the brackets 144 is four and spaced along the axial direction of the lock bar 141. Along the axial direction of the lock bar 141, both sides of the bracket 144 closest to the end of the lock bar 141 have the first limiting member 145.
[0090] In order to ensure the sealing performance of the discharge door 120 after being closed, the box door device 100 further comprises a sealing member located at the edge of the discharge door 120; in the state that the discharge door 120 is located at the closed position, the sealing member is sealingly connected to the door frame 114.
[0091] According to the box door device 100 of the embodiment, the first door lock assembly 130 can cooperate with the second door lock assembly 140, so as to ensure that the discharge door 120 is always located at the closed position when the locking member 132 is connected with the cooperating member 131. In the state that the locking member 132 is unlocked with the cooperating member 131, the goods will not force the discharge door 120 to open, which ensures the safety of the operation of the staff. When the container is tilted by the action of other external forces such as hoisting equipment, i.e. the first edge 112 is located at the second edge 113, the goods (gravity) in the container will impact the discharge door 120, and at the same time, the discharge door 120 will also pivot from the original closed position to the opening position under the action of its own gravity, so as to open the discharge door 120 and facilitate the discharge.
