DETAILED DESCRIPTION

[0048] In the following description, numerous specific details are given to provide a thorough understanding of the application. However, it will be apparent to one skilled in the art that the present application can be practiced without one or more of these specific details. In other instances, well-known techniques have not been described in detail in order to avoid unnecessarily obscuring the present application.

[0049] To thoroughly understand the present application, detailed structures will be presented in the following description. It is obvious that the implementation of the present application is not limited to the special details familiar to those skilled in the art.

[0050] The present application provides a door structure which is installed on the side wall of a container.

[0051] As​Figures 1 to 13 As shown, the door body structure according to the utility model comprises a door frame 10, a first flow guide groove 20 and at least one door body 30.

[0052] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 in the embodiment of the utility model, the door frame 10 comprises a vertical column 11 and an upper beam 12. The first flow guide groove 20 is connected to the bottom of the upper beam 12, the first flow guide groove 20 is the same as the extension direction of the upper beam 12, and the groove bottom 21 of the first flow guide groove 20 is directed to the bottom of the upper beam 12.

[0053] At least one door body 30, the door body 30 is pivotally connected to the vertical column 11.

[0054] The door body 30 comprises a body 31 and an extension 32, the extension 32 is connected to the top of the body 31, and the extension 32 extends a predetermined length from the top of the body 31 along the first direction F, so that when the door body 30 is in the closed state relative to the door frame 10, the extension 32 is located above the groove bottom 21, and the projection of the extension 32 on the vertical direction DH at least partially covers the groove bottom 21.

[0055] The first direction F is, when the door body 30 is in the closed state relative to the door frame 10, the direction from the side of the door body 30 directed to the other side of the door body 30 along the thickness direction DW of the door body structure. When it rains, rainwater will enter the inside of the door body 30 through the gap between the upper beam 12 of the door frame 10 and the top 301 of the door body. Based on this, the door body structure of the utility model adds the above-mentioned extension 32 to the top of the body 31 of the door body 30, and the door body structure of the utility model also adds the first flow guide groove 20, so that when the door body 30 is in the closed state relative to the door frame 10, the extension 32 is located above the groove bottom 21, and the projection of the extension 32 on the vertical direction DH at least partially covers the groove bottom 21. In this way, after the rainwater enters the gap between the upper beam 12 of the door frame 10 and the top 301 of the door body, it will flow into the first flow guide groove 20 along the extension 32, effectively avoiding the situation that the rainwater flows to the inside of the door body 30, and achieving a better rainproof effect.

[0056] It should be noted that the first flow guide groove 20 can be welded integrally with the bottom of the upper beam 12.

[0057] As shown in Figure 2 and Figure 6As shown in some preferred embodiments of the present utility model, the first flow guide groove 20 has a first groove wall 22 and a second groove wall 23 connected to both sides of the groove bottom 21, and the first groove wall 22 and the second groove wall 23 are spaced apart in the thickness direction DW of the door body structure.

[0058] The first groove wall 22 is farther away from the door body 30 than the second groove wall 23, and the top of the first groove wall 22 is connected to the bottom of the upper beam 12, preferably by welding.

[0059] The top of the second groove wall 23 is lower than the top of the first groove wall 22 in the vertical direction, so as to accommodate the extension 32 when the door body 30 is in the closed state relative to the door frame 10. When the extension 32 extends towards the first flow guide groove 20, the extension 32 does not interfere with the top of the second groove wall 23, i.e., the extension 32 can extend into the first flow guide groove 20 beyond the top of the second groove wall 23. In this way, rainwater can flow smoothly into the first flow guide groove 20 along the extension 32, effectively preventing rainwater from flowing to the inside of the door body 30.

[0060] As shown in some preferred embodiments of the present utility model, Figure 1 and Figure 2 The length of the extension 32 is configured such that, when the door body 30 is in the closed state relative to the door frame 10, the end of the extension 32 away from the body 31 abuts against the first groove wall 22. In this way, the extension length of the extension 32 can be substantially consistent with the width of the groove bottom 21 of the first flow guide groove 20, ensuring that rainwater flowing through the extension 32 can fall directly into the first flow guide groove 20. In addition, when the door body 30 is in the closed state, the sealing between the extension 32 and the first groove wall 22 can be ensured.

[0061] As shown in some preferred embodiments of the present utility model, Figure 2 the door body structure further comprises a flexible member 40.

[0062] When the door body 30 is in the closed state relative to the door frame 10, the flexible member 40 is clamped between the end of the extension 32 away from the body 31 and the first groove wall 22. By adding the flexible member 40, on the one hand, the sealing between the extension 32 and the first groove wall 22 can be improved, and on the other hand, the flexible member 40 can also act as a shock absorber when the door is closed, reducing the rigid contact between the extension 32 and the first groove wall 22, and further reducing the probability of deformation of the extension 32.

[0063] Preferably, the flexible member 40 can be fixed to the side end face of the extension 32 or to the surface of the first groove wall 22 facing the second groove wall 23 by adhesion.

[0064] In one specific embodiment of the present application, the flexible member 40 can be made of silica gel or rubber material, and can be in the form of a block or a strip. It should be noted that the flexible member 40 can only function as a seal, shock absorption and buffering, and the specific structure of the flexible member 40 is not limited.

[0065] As shown in Figure 2 and Figure 6 In some preferred embodiments of the present application, the upper beam 12 and the door body 30 are spaced apart in the vertical direction.

[0066] The door body structure further comprises a shielding portion 50 extending downward from the bottom of the upper beam 12 by a predetermined distance, and the bottom of the shielding portion 50 is not lower than the top 301 of the door body in the vertical direction, so as to effectively avoid the situation that the door body 30 cannot be opened or closed due to position interference when the door body 30 is opened or closed. In addition, in the thickness direction DW of the door body structure, the shielding portion 50 is located on the side of the first flow guide groove 20 close to the door body 30. That is, the shielding portion 50 and the door body 30 are spaced apart in the vertical direction, and the shielding portion 50 is located on the outermost side of the door body 30 in the vertical direction, so that when it rains, the shielding portion 50 is located at the front end of the gap between the bottom of the upper beam 12 and the top 301 of the door body, thereby playing a role in blocking rain to some extent and reducing the rain entering between the extension portion 32 and the first groove wall 22.

[0067] The so-called "front end" refers to the end close to the outer side of the door body 30.

[0068] As shown in Figure 2 , Figure 6 and 12, in the thickness direction DW of the door body structure, the shielding portion 50 is connected to the side surface of the upper beam 12 close to the door body 30.

[0069] In the present embodiment, the upper beam 12 comprises a first beam body 121 and a second beam body 122, the first beam body 121 is located above the second beam body 122 and connected to the second beam body 122, the first beam body 121 comprises an outer side wall 121a, in the thickness direction DW of the door body structure, the outer side wall 121a is located on the side of the first beam body 121 close to the door body 30, and the outer side wall 121a is located on the side of the second beam body 122 close to the door body 30, in the vertical direction, the outer side wall 121a extends downward and exceeds the bottom of the second beam body 122 by a predetermined distance to form the shielding portion 50. The function of the shielding portion 50 has been described in detail in the above embodiment, and will not be described here in detail for the sake of brevity.

[0070] In other alternative embodiments, the shielding portion 50 can also be a relatively independent component connected to the upper beam 12 by welding or other existing connection forms.

[0071] As Figure 9 shown, it is the overall structure diagram of the door frame 10 of the utility model.

[0072] As Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 13 As shown in some preferred embodiments of the utility model, the door body structure includes two columns 11, along the extension direction of the upper beam 12, two columns 11 are connected to both ends of the upper beam 12 respectively.

[0073] The inside of at least one column 11 is provided with a second flow guide groove 60, the extension direction of the second flow guide groove 60 is same with the column 11, the top of the second flow guide groove 60 is communicated with the first flow guide groove 20, and the bottom of the second flow guide groove 60 is communicated with the outside.The second flow guide groove 60 is arranged in the inside of the corresponding column 11, so that the rainwater flowing in the first flow guide groove 20 can be guided into the second flow guide groove 60, then the rainwater in the second flow guide groove 60 will flow out to the outside, in this way, by communicating at least one end of the first flow guide groove 20 with the corresponding second flow guide groove 60 respectively, a smooth flow path can be formed, so that the rainwater in the first flow guide groove 20 can be smoothly discharged to the outside, avoiding the inside of the door body 30 to store rainwater.

[0074] In the embodiment, preferably, the inside of both columns 11 is provided with the second flow guide groove 60.

[0075] As Figure 2 , Figure 6 , Figure 7 and Figure 13 As shown in some preferred embodiments of the utility model, the door frame 10 further includes a lower beam 70, the lower beam 70 is connected between the two columns 11, and the lower beam 70 is opposite to the upper beam 12 in the vertical direction.

[0076] The bottom of the second flow guide groove 60 extends to the top surface of the lower beam 70.

[0077] The door frame 10 further includes a door sill 80, the door sill 80 is located above the lower beam 70 and connected with the lower beam 70, in the thickness direction DW of the door body structure, the door sill 80 is located on the side of the second flow guide groove 60 away from the door body. In this way, the rainwater flowing through the first flow guide groove 20 and the second flow guide groove 60 in turn will fall on the top surface of the lower beam 70, at the same time, in order to avoid the rainwater flowing out of the end of the second flow guide groove 60 entering into the inside of the door body 30 through the gap between the bottom end of the lower beam 70 and the bottom end of the door body 30, by arranging the door sill 80 on the side of the second flow guide groove 60 away from the door body 30 in the thickness direction DW of the door body structure, the rainwater can be better blocked from entering into the inside of the door body 30, effectively avoiding the situation of rain leakage.

[0078] It should be noted that the bottom end surface of the door body 30 is higher than the top end surface of the lower beam 70 and lower than the top end surface of the door sill 80, so that the door body 30 can be smoothly opened and closed, and the door sill 80 can also have a better rain leakage prevention effect.

[0079] As shown in Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8 indicate that in some preferred embodiments of the utility model, the door body structure includes two upright columns 11, which are connected to both ends of the upper beam 12 along the extension direction of the upper beam 12.

[0080] The door body structure includes two door bodies 30, which are respectively pivotally connected with adjacent upright columns 11 to form a double-leaf door structure.

[0081] The two door bodies 30 are respectively a first door body 33 and a second door body 34, wherein during the process that the door body 30 is turned from the open state to the closed state relative to the door frame 10, the first door body 33 is in the closed state earlier than the second door body 34.

[0082] In the first door body 33, the side opposite to the pivotally connected upright column 10 is connected with a third flow guide groove 90, the third flow guide groove 90 has the same extension direction as the upright column 11, and along the thickness direction DW of the door body structure, the groove bottom of the third flow guide groove 90 faces the side of the door body 30 in the external environment.

[0083] In the second door body 34, the side opposite to the pivotally connected upright column 11 has a flange 93, and when the door body 30 is in the closed state relative to the door frame 10, the projection of the flange 93 on the thickness direction DW of the door body structure covers the groove bottom of the third flow guide groove 90. The width of the flange 93 is consistent with the width of the third flow guide groove 90, and when the door is closed, the above-mentioned flange 93 arranged at the end of the second door body 34 away from the door frame 10 can completely cover the third flow guide groove 90, so as to ensure the overall aesthetic appearance of the door body structure.

[0084] As shown in Figure 1 and Figure 5 indicate that in some preferred embodiments of the utility model, the extension part 32 in the first door body 33 is further connected with a fourth flow guide groove 91 away from the side of the upright column 11 pivotally connected with the first door body 33.

[0085] The fourth flow guide groove 91 has the same extension direction as the extension part 32, and the extension length of the fourth flow guide groove 91 does not exceed the extension part 32, and the groove bottom of the fourth flow guide groove 91 faces the bottom of the upper beam 12.

[0086] Along the extending direction of the fourth flow guide groove 91, one end of the fourth flow guide groove 91 is communicated with the third flow guide groove 90, and the other end of the fourth flow guide groove 91 is a closed end 92. The third flow guide groove 90 is communicated with the fourth flow guide groove 91, so that the rainwater entering the gap between the bottom of the upper beam 12 and the top 301 of the door body can also flow through the fourth flow guide groove 91 and the third flow guide groove 90 in turn and be discharged to the outside. At the same time, the end of the fourth flow guide groove 91 close to the inner side of the door body 30 is a closed end 92, so that it can play a certain blocking effect on the rainwater, avoiding the rainwater entering the inner side of the door body 30 through this place, and having a better rain leakage prevention effect.
