Description
Technical Field
[0001] The utility model relates to the field of bulk containers, in particular to a discharging door of a bulk container. Background Art
[0002] Figure 1 The following is a conventional structure at the discharging door of a bulk container in the prior art. The lock handle is located on the discharging door. When opening the discharging door, the operator needs to be in front of the discharging port, which has a certain safety risk. For example, when opening, the internal material may rush the discharging door outwards, which is likely to cause injury. And in order to meet the requirement of not exceeding the corner fittings, based on the fact that the door panel of the discharging door is a corrugated plate structure, the current position of the lock rod is external, occupying a certain space and reducing the internal space of the container. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a discharging door of a bulk container to increase the internal space of the container.
[0004] [[ID=X17]]To achieve the above purpose, the utility model provides the following technical solution: A discharging door of a bulk container covers the discharging port of the bulk container and is locked by a lock handle and a lock rod when covering. The discharging door includes a door panel and a cross beam. The middle part of the door panel is a corrugated plate structure. The top is connected to the bulk container through a hinge, and the bottom is welded to the cross beam. The cross beam is provided with a horizontal groove, and the lock rod is rotatably arranged in the groove.
[0005] Preferably, the end of the lock handle is hinged to one end of the lock rod, and the bulk container is provided with a handle lock for releasing or locking the lock handle. The handle lock is located beside the discharging port.
[0006] Preferably, the bulk container is provided with two lock seats, which are respectively located on both sides of the discharging port; both ends of the lock rod are provided with lock heads cooperating with the lock seats. Operating the lock handle can rotate the lock rod so that the lock rod is locked or unlocked with the lock seats.
[0007] Preferably, a plurality of support blocks are arranged inside the groove, and the support blocks are in direct contact with the door panel; a plurality of pressing plates are arranged outside the groove. Both ends of the pressing plate are fixed to the cross beam and are respectively located on the upper and lower sides of the groove; the pressing plates correspond to the support blocks one by one, and the lock rod is clamped between the pressing plate and the support plate and can rotate around an axis.
[0008] Preferably, the plurality of pressing plates are equidistantly distributed along the length direction of the cross beam.
[0009] Preferably, sealing rubber strips are arranged on the four peripheral edges of the discharging door.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] 1. The present utility model adjusts the structure of the discharge door, embeds the lock rod into the discharge door, slightly increases the length inside the box, and thus increases the volume inside the box.
[0012] 2. The present utility model moves the lock handle to the side of the discharge opening, which is more convenient and safe compared with the front door opening in the prior art. Description of the Drawings

[0016] Figure 4 is a transverse sectional view of the discharge door at the lock rod in the embodiment of the present utility model. Detailed Embodiment
[0017] Please refer to Figures 2 to 4 , a bulk cargo box discharge door is disclosed in the embodiment of the present utility model. The discharge door 2 covers the discharge opening of the bulk cargo box 1 and is locked by a lock handle 3 and a lock rod 4 when the discharge door 2 is closed.
[0018] The discharge door 2 in this embodiment includes a door panel 21 and a cross beam 22. The cross beam 22 is welded to the side of the door panel 21 facing the outside of the bulk cargo box 1. The top of the door panel 21 is connected to the outer side wall of the bulk cargo box 1 through a hinge 5. The middle part of the door panel 21 is a longitudinal corrugated structure 23, which is a conventional structure for strengthening the strength of the door panel 21. The cross beam 22 is located at the bottom of the door panel 21, that is, below the corrugated structure 23, and the thickness of the cross beam 22 is similar to the thickness of the corrugated structure 23.
[0019] The cross beam 22 is provided with a transverse groove. The present utility model adjusts the rotatable lock rod 4 originally arranged outside the corrugated structure 23 to be arranged in the groove inside the cross beam 22, slightly increases the length inside the bulk cargo box 1, and then increases the volume inside the box.
[0020] Specifically, a support block 24 is arranged inside the groove. The support block 24 is in direct contact with the door panel 21 and is equidistantly distributed along the length direction of the cross beam 22. A plurality of pressing plates 25 are arranged outside the groove. The plurality of pressing plates 25 are equidistantly distributed along the length direction of the cross beam 22, and each pressing plate 25 corresponds to a support block 24. Both ends of the pressing plate 25 are fixed to the cross beam 22 and are respectively located on the upper and lower sides of the groove. The locking rod 4 is clamped between the pressing plate 25 and the support plate and can rotate around an axis.
[0021] Two locking seats 11 are welded to the outer side of the bulk cargo box 1. The locking seats 11 are respectively located on both sides of the discharge opening. Lock heads that cooperate with the locking seats 11 are arranged at both ends of the locking rod 4. That is, based on the above structure, the locking rod 4 can only rotate around an axis between the pressing plate 25 and the support plate, and both of its ends are restricted in the locking seats 11, and the whole locking rod 4 cannot move axially.
[0022] The locking cooperation between the locking rod 4 and the locking seat 11 is generally achieved by an operator's operation on the lock handle 3. Operating the lock handle 3 can rotate the locking rod 4, so that the locking rod 4 is locked or unlocked from the locking seat 11. And the lock handle 3 itself is restricted by the handle lock 12. The present invention adjusts the positions of the lock handle 3 and the handle lock 12. The positions of the lock handle 3 and the handle lock 12 are adjusted from the door panel 21 of the discharge door 2 to the bulk cargo box 1: the end of the lock handle 3 is hinged to one end of the locking rod 4, and the handle lock 12 is welded to the outer side wall of the bulk cargo box 1 and is located beside the discharge opening at the same time, so as to realize the locking or release of the handle lock 12 on the lock handle 3.
[0023] With the above structure, the present invention enables the operator to operate the lock handle 3 beside the discharge opening to open and close the discharge door 2. Compared with the previous situation where the operator directly stood in front of the discharge opening to operate, it can better ensure the safety of the operator.
[0024] At the same time, in order to further enhance the sealing performance when the discharge door 2 is closed, sealing rubber strips 6 are arranged on the four peripheral edges of the discharge door 2.
[0025] In summary, by embedding the locking rod 4 into the discharge door 2, the present invention increases the length inside the box and expands the volume of the box; at the same time, it adjusts the operation position of the lock handle 3. The overall structure is simple, and the door opening and closing are convenient, fast and safe.
[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
