Description

Technical Field

[0001] The present application relates to the technical field of containers, and in particular to a door-enhanced container. Background Art

[0002] As the main carrier for cargo transportation, the structure and stability of the container door are crucial to the safe transportation of cargo.

[0003] The popular door designs on the market are mainly connected by hinged devices, where the hinged devices include door ears, hinge pins and door hinges. These door ears usually adopt a "U"-shaped structure, and the hinge pins pass through the door ears and door hinges. The other end of the door hinge is fixed to the door, thereby realizing the hinge connection of the door. However, when fixing the door ears, they need to be welded to the box body on the upper and lower sides to form a welding seam. This traditional "U"-shaped door ear is prone to deformation after welding, resulting in a larger size. Furthermore, after assembling the hinge pin, the excessive assembly gap caused by deformation will cause the door to sag as a whole, seriously affecting the sealing effect of the upper end of the door. These problems may eventually lead to a series of adverse consequences such as light leakage and water leakage, posing a threat to the safe transportation of goods.

[0004] Therefore, how to enhance the strength and precision of the door joints to prevent them from deforming has become a technical problem that needs to be solved urgently. Utility Model Content

[0012] By adopting the above technical solution, the integrity and strength of the structure are improved.

[0013] Optionally, a plurality of the first reinforcing ribs are arranged along the welding direction of the base.

[0014] By adopting the above technical solution, the connection strength between the box door and the box body is further enhanced.

[0021] By adopting the above technical solution, a relatively stable connection between the connecting plate and the bottom plate can be achieved.

[0022] Optionally, a connecting rod is provided between the two connecting plates.

[0023] By adopting the above technical solution, the connecting rod positions the distance between the two connecting plates, further improving the accuracy of fixing the hinge pin, and also enhancing the strength of the two connecting plates.

[0024] In summary, the present application includes at least one of the following beneficial effects:

[0025] 1.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a door-enhanced container. Figure 1 The container comprises a box body 1, a box door 2 hinged to the box body 1, and a hinge device for connecting the box door 2 and the box body 1. The hinge device comprises a door ear 3, a hinge pin 4 and a door hinge 5, wherein the door ear 3 is fixed to the side wall of the container by welding, the door hinge 5 is fixed to the side wall of the box door 2 by welding or other means, the door ear 3 is provided with two connection holes 321 for the hinge pin 4 to pass through, the door hinge 5 is rotatably connected to the door ear 3 through the hinge pin 4, so that the box door 2 is rotatably connected to the box body 1.

[0033] Reference Figure 1 and Figure 2In this embodiment, specifically, the door ear 3 includes a base 31, a connecting plate 32 and a fixing member 33. The connecting plate 32 is respectively arranged on the upper and lower side plates of the base 31 through the fixing member 33, and two connecting holes 321 for the hinge pin 4 to pass through are respectively opened on the two connecting plates 32; wherein the cross section of the base 31 is a "[" shape, and the outer side wall of the base 31 is fitted and fixed on the container, and at the same time, the upper and lower side walls of the base 31 are both provided with a first reinforcing rib 311, one side of the first reinforcing rib 311 is integrally formed on the upper and lower side walls of the base 31, and the back of the first reinforcing rib 311 is One side edge away from the box body 1 is flush with the end edge of the base 31 away from the box body 1; the other side of the first reinforcing rib 311 extends toward the side wall of the box body 1, and is located on the same plane as the outer side wall of the base 31 close to the box body 1, forming a positioning surface, so that when the base 31 is placed on the side wall of the box body 1, the positioning surface of the first reinforcing rib 311 can also abut against the side wall of the box body 1, and when the upper and lower sides of the base 31 are welded, the interaction force between the first reinforcing rib 311 and the box body 1 can limit the outward deformation of the base 31, that is, it can reduce the deformation of the base 31 after welding.

[0034] Furthermore, a triangular-shaped clearance groove is provided at the position of the first reinforcing rib 311 toward the welding position of the base 31, so as to facilitate welding of the base 31. The positioning surface of the first reinforcing rib 311 is also welded and fixed to the box body 1. Through the clearance groove, the distance between the welding position of the first reinforcing rib 311 and the welding position of the base 31 can also be increased, thereby avoiding the stress concentration problem that may be generated during the welding process. A plurality of first reinforcing ribs 311 are arranged at intervals along the extension direction of the weld of the base 31, thereby improving the overall structural strength and stability.

[0035] Reference Figure 1 and Figure 2 In this embodiment, further, a second reinforcing rib 312 may be integrally formed on the inner wall of the inner side wall of the base 31. The cross section of the second reinforcing rib 312 may be triangular, and is preferably provided on the upper and lower side walls inside the base 31, respectively, so as to further improve the stability of the upper and lower side panels of the base 31. A plurality of second reinforcing ribs 312 may also be provided at intervals along the extension direction of the weld of the base 31. Preferably, the position of the second reinforcing rib 312 may be provided opposite to the position of the outer first reinforcing rib 311.

[0036] Reference Figure 2 and Figure 3In this embodiment, a slot for the corresponding side plate of the base 31 to be plugged into is provided on the side wall of the connecting plate 32 facing the base 31, and a card slot for the first reinforcing rib 311 to be plugged into is also provided on the side of the connecting plate 32 facing the base 31; in actual use, the base 31 is first welded to the side wall of the box body 1, and then the two connecting plates 32 are respectively plugged into the upper and lower side plates of the base 31, and fixed by the fixing parts 33. At this time, when the base 31 is welded, it is not easy to deform due to the action of the first reinforcing rib 311 and the second reinforcing rib 312. After the base 31 is welded, the distance accuracy between the two connecting holes 321 on the door ear 3 can be further guaranteed by plugging in the connecting plate 32.

[0037] Reference Figure 2 and Figure 3 In this embodiment, the fixing member 33 includes a fixing bolt 331 and a fixing nut 332. The fixing bolt 331 can pass through the connecting plate 32 and the base 31 in sequence and be threadedly connected with the fixing nut 332. The fixing bolt 331 and the fixing nut 332 can also be arranged in multiple groups along the extending direction of the weld of the base 31, so as to ensure that the connecting plate 32 is stably fixed on the base 31. When the door 2 is in use, the connecting hole 321 on the connecting plate 32 is the main stress point. After long-term use, the connecting hole 321 may be deformed or damaged. Therefore, through this splicing fixing method, the connecting plate 32 can be easily replaced, so as to always keep the accurate positioning of the door 2.

[0038] Reference Figure 2 and Figure 3 In an optional embodiment, a connecting rod 322 can be integrally formed between the two connecting plates 32. It should be noted that the connecting rod needs to avoid the rotation position of the door hinge 5 when it is set. By adding the connecting rod 322, the distance between the two connecting holes 321 can be further accurately guaranteed, and at the same time, the force stability of the two connecting plates 32 can be improved during use.

[0039] The implementation principle of a door-enhanced container in an embodiment of the present application is as follows: by arranging a first reinforcing rib 311 and a second reinforcing rib 312 on the base 31, the stability of the upper and lower side panels of the base 31 can be improved, and the deformation of the base 31 that may occur during welding can be reduced; at the same time, by splicing and fixing the connecting plate 32 and the base 31, it is possible to avoid partial heat deformation of the connecting plate 32 when the bottom plate is welded, thereby further improving the accuracy of the distance between the two connecting plates 32.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
