Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0040] For the transport container for transporting liquid, solid bulk or powder, in order to facilitate the unloading of goods, usually in the bottom surface of the transport container is provided with discharge port, so that the goods in the transport container under the action of gravity, unloading. But due to the accumulation of goods in the transport container, will form pressure on the upper part of the sliding discharge door, so that the discharge door in the horizontal sliding, need to overcome the great friction, sometimes even difficult to open the discharge door, so as to affect the use of the transport container.

[0041] At the same time, in order to facilitate the opening of the discharge door, usually through a lever horizontal swing and drive the movement of the pull piece, the other end of the pull piece hinge discharge door, thus driving the discharge door to move open. However, through this way to open the discharge door, the moving direction of the pull piece will change with the swing of the lever, and the moving direction of the pull piece and the moving direction of the discharge door form a certain angle, will make the lever on the process of opening the discharge door, the force transmitted to the discharge door gradually decreases. In addition, due to the limited swing angle of the lever, the moving distance of the pull piece and the discharge door is limited, in the case of long discharge door, it is easy to cause the discharge door can not be completely opened. Therefore, the present application provides a discharge door structure of the transport container to solve the above problems.

[0042] The scheme is further illustrated by the following embodiments:

[0043] Please refer to Figures 1-3 The transport container of the embodiment includes a discharge door structure, a support frame 2 and a funnel-shaped container 3. Among them, the funnel-shaped container 3 is used to load goods, such as solid bulk or powder, and the bottom surface of the funnel-shaped container 3 is provided with a discharge port to facilitate the unloading of the goods in the transport container through the discharge port. In this embodiment, the funnel-shaped container 3 is fixed on the support frame 2, and the discharge port is located at the bottom of the support frame 2 and opens downward. The discharge door structure is detachably connected to the support frame 2 and located at the discharge port of the bottom surface of the transport container, so as to open or close the discharge port. That is, when the discharge door structure closes the discharge port, the transport container can load the goods and complete the transportation of the goods; when the discharge door structure opens the discharge door, the goods in the transport container can be automatically unloaded from the transport container under the action of gravity, thereby completing the transfer of the goods.

[0044] Please refer to Figures 3-7 The discharge door structure includes a discharge door 1 and an auxiliary mechanism, wherein the discharge door 1 is arranged on the bottom surface of the transport container and located below the discharge port. At the same time, the discharge door 1 can move in the horizontal direction, so as to open or close the discharge port. The auxiliary mechanism is connected between the discharge door 1 and the transport container to drive the sliding of the discharge door 1 to open or close the discharge door 1.

[0045] Meanwhile, the auxiliary mechanism comprises the handle 10, the connecting piece 20 and the hook pulling piece 30. The handle 10 is detachably connected to the transport container at one end, and the handle 10 can rotate relative to the transport container. The connecting piece 20 is detachably connected to the discharge door 1 at one end, and the connecting piece 20 can rotate relative to the discharge door 1. Meanwhile, the other end of the connecting piece 20 is connected to the handle 10, and the connecting piece 20 can slide relative to the handle 10. A plurality of pulling grooves 21 are arranged on the connecting piece 20 along the length direction of the connecting piece 20. The hook pulling piece 30 is provided with hook heads 31 matched with the pulling grooves 21, and one end of the hook pulling piece 30 is hinged to the handle 10, so that when the hook pulling piece 30 rotates relative to the handle 10, the hook heads 31 on the hook pulling piece 30 can be clamped into the pulling grooves 21 at different positions, and when the handle 10 rotates relative to the transport container, the handle 10 can drive the connecting piece 20 and the discharge door 1 to move through the hook pulling piece 30, so as to open the discharge door 1.

[0046] In the embodiment, since the pulling grooves 21 are arranged along the length direction of the connecting piece 20, and the hook heads 31 of the hook pulling piece 30 are clamped into the pulling grooves 21 at different positions, when the handle 10 drives the hook pulling piece 30 to rotate, the hook heads 31 can be matched with the pulling grooves 21 at different positions by changing the matching relationship between the hook heads 31 and the pulling grooves 21, so as to drive the connecting piece 20 and the discharge door 1 to move. That is, when the handle 10 drives the connecting piece 20 to move through the hook pulling piece 30, after the connecting piece 20 moves a distance, the matching relationship between the hook heads 31 on the hook pulling piece 30 and the pulling grooves 21 on the connecting piece 20 is changed, and then the handle 10 is rotated, so that the handle 10 and the hook pulling piece 30 can drive the connecting piece 20 to move through the pulling grooves 21 at different positions on the connecting piece 20, so as to adjust the torque between the handle 10 and the connecting piece 20 during the opening process of the discharge door 1, and adjust the position where the handle 10 and the hook pulling piece 30 exert the pulling force on the connecting piece 20, so as to expand the distance where the handle 10 drives the connecting piece 20 to move within the limited rotation range of the handle 10, thereby achieving the purpose of saving labor and expanding the moving range of the connecting piece 20 and the discharge door 1.

[0047] Referring to Figures 8-11 The handle 10 comprises a handle 12, a connecting plate 13 and two supporting plates 14. The two supporting plates 14 are arranged at the two sides of the connecting piece 20 to limit the connecting piece 20, so as to prevent the connecting piece 20 from changing the posture when the connecting piece 20 slides relative to the handle 12. Meanwhile, the handle 12 and the connecting plate 13 are connected to the two ends of the length direction of the two supporting plates 14, respectively. The end of the connecting plate 13 away from the supporting plate 14 is detachably connected to the transport container, and can rotate relative to the transport container, so that the handle 10 can rotate relative to the transport container. In addition, one end of the hook pulling piece 30 is arranged between the two supporting plates 14 and is hinged to the supporting plates 14, so that the hook pulling piece 30 can rotate relative to the supporting plates 14.

[0048] In some other embodiments, the support plate 14 can also be provided as one, and the handle 12 and the connecting plate 13 are connected at two ends of the support plate 14 respectively, so that the handle 12, the connecting plate 13 and the support plate 14 are connected as an integral handle 10, or the connecting plate 13 is cancelled and the support plate 14 is lengthened to replace the function of the connecting plate 13. At the same time, the end of the connecting piece 20 away from the discharge door 1 is limited on the support plate 14 and can slide relative to the support plate 14, so that when the handle 10 rotates relative to the transport container, the handle 10 can drive the connecting piece 20 and the discharge door 1 to move through the hooking piece 30, and prevent the connecting piece 20 from changing posture.

[0049] Referring to Figure 5 and Figure 8 , the end of the connecting piece 20 connected to the discharge door 1 is provided with a connecting groove 22, and the discharge door 1 is provided with a pull rod 101 matched with the connecting groove 22, so that the connecting groove 22 can be clamped on the side of the pull rod 101. Among them, the pull rod 101 is fixedly connected on the discharge door 1 and located on the side edge of the discharge door 1, so that the connecting piece 20 can drive the discharge door 1 to move in the horizontal direction through the pull rod 101.

[0050] Referring to Figure 9 and Figure 12 , the connecting groove 22 is provided with a downwardly opening notch 221, and the notch 221 is provided with a horizontally extending protruding portion 222, and the protruding portion 222 extends away from the side of the discharge door 1, so as to be capable of clamping the pull rod 101.

[0051] In this embodiment, the connecting piece 20 is detachably connected with the pull rod 101 through the connecting groove 22, that is, the connecting groove 22 is clamped on the side of the pull rod 101 through the notch 221, and when the connecting piece 20 moves in the horizontal direction away from the discharge door 1, the protruding portion 222 can be supported on the bottom wall of the pull rod 101, thereby supporting the pull rod 101 and preventing the pull rod 101 from falling out of the connecting groove 22 during movement.

[0052] Referring to Figure 8 and Figure 9 , the connecting piece 20 is provided with a counterweight 23. Among them, the counterweight 23 is connected to the connecting piece 20 and located above the connecting groove 22, so that during the movement of the connecting piece 20, the counterweight 23 can press the end of the connecting piece 20 provided with the connecting groove 22 downward on the pull rod 101, that is, the connecting groove 22 is pressed on the side of the pull rod 101, thereby avoiding the connecting groove 22 from being separated from the pull rod 101 during the movement of the connecting piece 20.

[0053] It should be noted that in some other embodiments, the protruding portion 222 can also not be provided, and the counterweight 23 can be used to ensure that the pull rod 101 does not fall out of the connecting groove 22 during movement.

[0054] It should be noted that in other embodiments, the counterweight 23 can not be provided, and other limiting stoppers such as movable limiting pins can be used to limit the pull rod 101 in the connecting groove 22 above the protruding portion 222. Through the limiting of the protruding portion 222 and the movable limiting pin, it is ensured that the pull rod 101 does not fall out of the connecting groove 22 during movement.

[0055] Referring to Figure 7 and Figure 12 , the limiting groove 24 is formed on the connecting piece 20 along the length direction of the connecting piece 20. Meanwhile, the limiting shaft 11 for supporting and limiting the connecting piece 20 is arranged on the handle 10, and the limiting shaft 11 is arranged in the limiting groove 24, so that the connecting piece 20 can slide relative to the handle 10.

[0056] In the embodiment, the limiting shaft 11 is connected between the two supporting plates 14 and arranged in the limiting groove 24, so as to limit and support the connecting piece 20, so that the connecting piece 20 can slide and rotate relative to the handle 10, and the posture of the connecting piece 20 is prevented from changing.

[0057] Referring to Figure 8 and Figure 9 , the hooking piece 30 is located above the connecting piece 20, so that when the hooking piece 30 rotates relative to the handle 10 under the action of gravity, the hook head 31 can be clamped into the pulling groove 21. That is, during the rotation of the handle 10 driving the hooking piece 30, the hook head 31 of the hooking piece 30 can be clamped into the pulling groove 21 due to the gravity of the hooking piece 30, and the hook head 31 is prevented from being separated from the pulling groove 21 during the rotation of the hooking piece 30 with the handle 10.

[0058] It should be noted that in other embodiments, the hooking piece 30 can also be arranged on the side of the connecting piece 20, and of course a pre-tightening mechanism is required to press the hook head 31 of the hooking piece 30 against the pulling groove 21 of the connecting piece 20, so that the hook head 31 can be continuously clamped in the pulling groove 21 during the rotation of the handle 10 driving the hooking piece 30, thereby enabling the hooking piece 30 to continuously drive the connecting piece 20 to move.

[0059] Referring to Figure 8 and Figure 9 , the pulling groove 21 is located at the top of the connecting piece 20, and the hook head 31 is located at the bottom of the end of the hooking piece 30 away from the handle 10, so that when the hook head 31 rotates relative to the handle 10 under the action of gravity, the hook head 31 can be clamped into the pulling groove 21, that is, after the hooking piece 30 rotates relative to the handle 10, the hook head 31 of the hooking piece 30 can be clamped into the pulling groove 21 at different positions.

[0060] It should be noted that the pull slot 21 can also be arranged on both sides of the length direction of the connecting piece 20, and the hook pull piece 30 is located on the side of the connecting piece 20, so that the hook head 31 of the hook pull piece 30 can be clamped into the pull slot 21 at different positions.

[0061] Referring to Figure 12 , the pull slot 21 includes a guide surface 211, a slot bottom surface 212, and an abutting surface 213. Among them, the slot bottom surface 212 extends along the length direction of the connecting piece 20, the guide surface 211 and the abutting surface 213 are respectively located at both ends of the length direction of the slot bottom surface 212, and the guide surface 211 is located at one end of the slot bottom surface 212 towards the discharge door 1. At the same time, the guide surface 211 is inclined from the slot bottom surface 212 to the top of the connecting piece 20 towards one side of the discharge door 1, so as to guide the hook head 31 to exit the pull slot 21. The abutting surface 213 is inclined from the slot bottom surface 212 to the top of the connecting piece 20 towards one side of the discharge door 1, so as to abut the hook head 31, prevent the hook head 31 from being automatically separated from the pull slot 21 when the hook head 31 drives the connecting piece 20 to move through the pull slot 21, and because the inclination of the abutting surface 213 is insufficient.

[0062] Referring to Figure 13 , the hook head 31 includes a hook head inclined surface 311, a hook head bottom surface 312, and an abutting surface 313. Among them, the hook head bottom surface 312 and the abutting surface 313 are respectively matched with the slot bottom surface 212 and the abutting surface 213, so that the hook head 31 can be clamped into the pull slot 21 and drive the connecting piece 20 to move. The hook head inclined surface 311 is matched with the guide surface 211, so that the hook head 31 can exit the pull slot 21.

[0063] It should be noted that in the embodiment, the hook pull piece 30 further includes a hand holding portion 32. Among them, the hand holding portion 32 is located at one end of the hook pull piece 30 away from the handle 10 and above the hook head 31, so that the operator can manually adjust the clamping of the hook head 31 at different positions through the hand holding portion 32, and then complete the movement of the connecting piece 20 and the discharge door 1.

[0064] Of course, since the hook pull piece 30 is provided with the hook head inclined surface 311, and the pull slot 21 is provided with the guide surface 211. Therefore, when the handle 10 is pushed and drives the hook pull piece 30 to move, the hook head inclined surface 311 can slide along the guide surface 211, and the hook pull piece 30 is clamped into another pull slot 21 close to the discharge door 1, so as to adjust the position of the hook pull piece 30 and the pull slot 21, and facilitate the movement of the discharge door 1 through the connecting piece 20 by the hook pull piece 30.

[0065] It should be noted that in other embodiments, only the guide surface 211 or only the hook head inclined surface 311 can be provided, and when the handle 10 is pushed and the hook puller 30 is moved, the guide surface 211 or the hook head inclined surface 311 can also guide the hook puller 30 to exit the pull slot 21 and make the hook puller 30 clamped into another pull slot 21 close to the discharge door 1.

[0066] In addition, referring to Figure 9 , in the embodiment, the hook puller 30 is connected between the two support plates 14 through the shaft, so that the hook puller 30 can rotate relative to the handle 10. At the same time, under the mutual limiting of the two support plates 14, the hook puller 30 can rotate in a specific direction, avoiding the posture transformation of the hook puller 30 during rotation.

[0067] Referring to Figures 7-9 , in the embodiment, the auxiliary mechanism further includes a base 40. Wherein, the base 40 is connected between the transport container and the connecting plate 13, and the base 40 is provided with a clamping part 41 at one end along the length direction of the base 40, and the other end is hinged with the connecting plate 13. The base 40 is detachably connected to the transport container through the clamping part 41, so that the auxiliary mechanism can be conveniently installed on the transport container, or detached from the transport container.

[0068] It should be noted that the clamping part 41 is matched with the connection position on the transport container, so that the clamping part 41 can be quickly connected to the transport container. For example, the clamping part 41 can be connected with the transport container through bolts, or can be connected through a buckle structure, so that the base 40 can be quickly connected to the transport container.

[0069] Referring to Figure 8 and Figure 9 , the base 40 includes an end plate 42, a top plate 43, a side plate 44 and a mounting plate 45 connected in sequence. Wherein, the end plate 42 and the side plate 44 both extend along the vertical direction and are arranged on the opposite sides of the top plate 43 in a spaced manner, so that the end plate 42, the top plate 43 and the side plate 44 together form the clamping part 41, that is, the top plate 43 is connected between the end plate 42 and the side plate 44 and located at the top of the two. The top plate 43 and the mounting plate 45 both extend along the horizontal direction and are connected at the upper and lower ends of the side plate 44 respectively.

[0070] In the embodiment, the end plate 42, the top plate 43 and the side plate 44 together form a rectangular groove-shaped clamping part 41, and the bottom of the support frame 2 is also provided with a rectangular beam matched with the rectangular groove-shaped clamping part 41, and the rectangular groove-shaped clamping part 41 can be clamped on the rectangular beam, so that the auxiliary mechanism can be detachably connected to the transport container.

[0071] It should be noted that in the present embodiment, a rib plate 46 is further arranged between the side plate 44 and the mounting plate 45 to enhance the connecting strength between the side plate 44 and the mounting plate 45.

[0072] As can be seen, the auxiliary mechanism is detachably connected to the discharge door 1 and the support frame 2 through the connecting piece 20 and the base 40, so that the auxiliary mechanism can be installed and detached according to actual needs, thereby facilitating the use of the auxiliary mechanism and the transportation of the transport container. Meanwhile, a plurality of pull grooves 21 are formed on the connecting piece 20 along the length direction thereof, and the hook head 31 of the hook pull piece 30 can be clamped into the pull grooves 21 at different positions, so that the hook pull piece 30 is driven by the handle 10 to move the connecting piece 20 along the horizontal direction through the cooperation between the hook head 31 and the pull grooves 21, thereby driving the discharge door 1 to move along the horizontal direction, and further opening the discharge port of the transport container. Moreover, the hook head 31 can be adjusted to cooperate with the pull grooves 21 at different positions, so that the connecting piece 20 is driven to move with a smaller torque during the rotation or swing of the handle 10, thereby achieving the purpose of saving labor, and the moving distance of the connecting piece 20 and the discharge door 1 can be increased.
