[0050] Reference can be made to Figure 1 , the present utility model provides a door body 10, the door body 10 includes a first door panel 11 and a second door panel 12, the first door panel 11 is adapted to be rotatably connected to the first beam 21 of the door frame 20 and the second door panel 12 is rotatably connected to one end of the first door panel 11 away from the first beam 21; in the first state, the first door panel 11 and the second door panel 12 have a first included angle, and both the first door panel 11 and the second door panel 12 are adapted to be connected to the door frame 20 and close the door frame 20; in the second state, the first door panel 11 and the second door panel 12 have a second included angle, there is a gap between the second door panel 12 and the door frame 20, and the first included angle is greater than the second included angle; during the process of switching from the first state to the second state, one end of the second door panel 12 close to the first door panel 11 moves away from the door frame 20, and the end of the second door panel 12 away from the first door panel 11 moves towards the first beam 21.

[0051] The first door panel 11 and the second door panel 12 can be solid wood boards, metal plates, density boards, etc. Specifically, the metal plate can be a stainless steel plate or an aluminum alloy plate, without limitation. Specifically, the first door panel 11 and the second door panel 12 can be formed by a rectangular tube to form a frame and then filled with sheet metal parts, so that while ensuring the structural strength of the door body 10, the weight of the door panel is reduced to the greatest extent, saving space and weight.

[0052] Optionally, the way of rotatably connecting the second door panel 12 to one end of the first door panel 11 away from the first beam 21 can be pin connection, socket connection, roller connection, cycloid connection, gear connection, universal joint connection, etc., without limitation.

[0055] The second included angle is the included angle between the first door panel 11 and the second door panel 12 when there is a gap between the second door panel 12 and the door frame 20.

[0056] Optionally, the door body 10 further includes a door tie rod lock 13. The door tie rod lock 13 is arranged at the end of the first door panel 11 close to the column 22. The door tie rod lock 13 includes a connecting rod, a lock cover and a lock head. When the connecting rod is pulled or pushed, the lock head performs corresponding actions to lock and unlock the door body 10. The lock cover cooperates with the connecting rod to protect the internal structure of the door tie rod lock 13.

[0057] The door body 10 of the present utility model realizes the closing and opening of the door body 10 to the door frame 20 by arranging the first door panel 11 and the second door panel 12 that can be switched between the first state and the second state. During the process of switching from the first state to the second state, the second door panel 12 moves towards the first beam 21 to reduce the included angle between the first door panel 11 and the second door panel 12, so that the door body 10 is in a form of folding up and down. Compared with the form of folding left and right, the door body 10 of the present utility model does not need to be provided with an additional vertical beam structure. After the door body 10 is applied in the container, the space utilization rate inside the container can be increased. And in the second state of the door body 10 of the present utility model, there is a gap between the second door panel 12 and the door frame 20, enabling the door frame 20 to be fully opened, which is beneficial to the entry and exit of products.

[0058] For reference Figure 2 In one embodiment, in the second state, the second door panel 12 is arranged on the side of the first door panel 11 facing the ground. That is, during the process of the door body 10 realizing the opening of the door frame 20, the first door panel 11 and the second door panel 12 move in a direction away from the ground, and the second door panel 12 is located on the side of the first door panel 11 facing the ground. The door body 10 is in an overall state of folding up and down. That is, in the second state, a structure in which the first door panel 11 covers the second door panel 12 is presented, achieving preliminary waterproofing in terms of structure.

[0059] For reference Figure 1 and Figure 2 In one embodiment, the first door panel 11 includes opposite first end 111 and second end 112. The first end 111 is adapted to be rotatably connected to the first beam 21. The second door panel 12 includes opposite third end 121 and fourth end 122. The second end 112 is rotatably connected to the third end 121. The door body 10 further includes a first hinge 14. The first door panel 11 and the second door panel 12 are connected by the first hinge 14.

[0060] There may be multiple first hinges 14, and the multiple first hinges 14 are arranged at intervals. The connection mode of the first hinge 14 to the second end 112 and the third end 121 may be screwed connection.

[0061] For reference Figure 1, Optionally, the door body 10 further includes a second hinge 15. The first end 111 and the first beam 21 are rotatably connected through the second hinge 15. There may be multiple second hinges 15, and the multiple second hinges 15 are spaced apart on the first beam 21, enabling the first door panel 11 to be rotatably connected to the first beam 21.

[0062] By providing the first hinge 14 and the second hinge 15 to achieve the rotational connection between the first door panel 11 and the first beam 21, and the rotational connection between the second door panel 12 and the first door panel 11, the door body 10 can smoothly switch between the first state and the second state.

[0063] For reference Figure 2 , Figure 3 and Figure 5 , In one embodiment, the door body 10 further includes a first rubber strip 16. The first rubber strip 16 is disposed at the connection between the first door panel 11 and the second door panel 12, and the first rubber strip 16 extends along the extension direction of the first beam 21.

[0064] The material of the first rubber strip 16 can be polyurethane, epoxy resin, polyethylene, silica gel, rubber, etc., without limitation.

[0065] There may be two first rubber strips 16, which are respectively disposed at the connection near the door frame 20 of the second end 112 and the third end 121 and at the connection far from the door frame 20 of the second end 112 and the third end 121.

[0066] Optionally, a connecting portion is further provided at the connection between the first door panel 11 and the second door panel 12. A receiving hole is formed on the connecting portion. The connecting portion is disposed at the end of the second end 112 and the third end 121 in the first direction and connects the second end 112 and the third end 121. The two ends of the first rubber strip 16 are correspondingly received in the receiving hole, and the receiving hole is filled with glue to ensure the waterproof effect and the installation reliability of the first rubber strip 16.

[0067] Optionally, rainproof strips are also provided at the two ends of the door body 10 extending in the second direction. The connection method between the rainproof strips and the door body 10 can be bonding, snap - fitting, etc., without limitation. By providing the rainproof strips, when the container is outdoors in heavy rain, it can initially prevent rainwater from directly irrigating, and the sealing effect of the remaining rubber strips of the door body 10 is not easily invalidated.

[0068] By providing the first rubber strip 16 at the connection between the second end 112 and the third end 121, the waterproofing at the connection between the first door panel 11 and the second door panel 12 is achieved.

[0069] , In one embodiment, the first rubber strip 16 has a hollow structure. The first rubber strip 16 with a hollow structure has a large compression allowance, so that when the first door panel 11 and the second door panel 12 switch between the first state and the second state, it can always maintain good waterproof sealing performance, extending the service life of the door body 10.

[0070] In one embodiment, the distance from the first end 111 to the second end 112 is h1, and the distance from the third end 121 to the fourth end 122 is h2, satisfying: 1.45 ≤ h1 / h2 ≤ 1.55.

[0071] Optionally, h1 / h2 can be 1.45, 1.48, 1.5, 1.52, 1.55, etc., without limitation. Specifically, h1 is 1700 mm and h2 is 1130 mm. When h1 / h2 > 1.55, the ratio of the sizes of the first door panel 11 and the second door panel 12 is too large. In the second state, after the second door panel 12 is opened, the space reserved in the second direction of the container is small, which is not conducive to operations such as handling the devices inside the container; when h1 / h2 < 1.45, the ratio of the sizes of the first door panel 11 and the second door panel 12 is too small. In the second state, the fourth end 122 of the second door panel 12 may extend into the container, affecting the components of the container; when 1.45 ≤ h1 / h2 ≤ 1.55, the second door panel 12 can avoid the other components of the container while leaving enough operating space when the container is open.

[0072] h1 can be considered as the length of the first door panel 11, and h2 can be considered as the length of the second door panel 12. By limiting the ratio of the first door panel 11 and the second door panel 12, during the process of switching between the first state and the second state, the second door panel 12 can avoid the other components of the container, such as the hydraulic rod 24, the pull rod 23, etc., preventing the second door panel 12 from interfering with the other components.

[0073] In one embodiment, in the second state, the included angle between the first door panel 11 and the column 22 of the door frame 20 is a1, satisfying: 100° ≤ a1 ≤ 110°.

[0074] a1 can be 100°, 103°, 105°, 108°, 110°, etc., without limitation.

[0075] Setting a1 limits the included angle between the first door panel 11 and the column 22 when the container is fully opened, so that the first door panel 11 can be fully opened in the second state, driving the second door panel 12 at the same time, enabling the container to be fully opened, and at the same time, the first door panel 11 and the second door panel 12 can also avoid the components inside the container, which is beneficial to improving the space utilization rate inside the container.

[0076] In one embodiment, the second included angle is a2, satisfying: 10° ≤ a2 ≤ 20°.

[0077] a2 can be 10°, 12°, 15°, 18°, 20°, etc., without limitation.

[0078] In the second state, the included angle a2 between the first door panel 11 and the second door panel 12 is defined, and the size ratio between the first door panel 11 and the second door panel 12 is also defined, so that when the door body 10 opens the door frame 20, the fourth end 122 of the second door panel 12 is closer to the door frame 20 than the second end 112 of the first door panel 11, and the fourth end 122 can be as far away from the ground as possible, facilitating the movement of devices inside the container.

[0079] Reference can be made to Figure 1 , The present utility model provides a folding door 100, including a door frame 20 and the door body 10 described in any one of the foregoing various embodiments. The door frame 20 includes a first beam 21 and a column 22. The first beam 21 is connected to the column 22, and the first door panel 11 is rotatably connected to the first beam 21.

[0080] Optionally, the door frame 20 is composed of multiple rectangular tubes, and the connection method of the rectangular tubes can be welding, screwing, etc.

[0081] Optionally, the column 22 is a first column and a second column. One end of the first beam 21 is connected to the end of the first column away from the ground, and the other end of the first beam 21 is connected to the end of the second column away from the ground. The column 22 and the first beam 21 can be an integral structure or a split structure, without limitation.

[0082] In the first state, the folding door 100 seals the box body 200 of the container. In the second state, the folding door 100 is in an up-and-down folding state to open the box body 200 of the container. During the process of switching from the first state to the second state, the second door panel 12 moves towards the first beam 21 to reduce the included angle between the first door panel 11 and the second door panel 12, so that the door body 10 is in an up-and-down folding form. Compared with the left-and-right folding form, the door body 10 of the present utility model does not need to be provided with an additional vertical beam structure, and the space utilization rate inside the container can be increased after the door body 10 is applied to the container.

[0083] Reference can be made to Figure 2 、 Figure 3 and Figure 5 , In one embodiment, the folding door 100 further includes a pull rod 23. One end of the pull rod 23 is rotatably connected to the first beam 21, and the other end of the pull rod 23 is rotatably connected to the second door panel 12.

[0084] The pull rod 23 is a member with a certain structural strength. The pull rod 23 can be made of stainless steel, aluminum alloy, high-strength plastic, etc., without limitation.

[0085] Optionally, there are two pull rods 23, which are arranged at two ends of the first beam 21 in the first direction, so that the acting force of the pull rods 23 on the second door panel 12 can be symmetrical in the first direction, which is beneficial to the opening of the folding door 100.

[0086] During the process of switching from the first state to the second state, the pulling force generated by the movement of the pull rod 23 on the second door panel 12 causes the second door panel 12 to fold as the first door panel 11 moves. When the first door panel 11 moves to the uppermost end, the second door panel 12 is also pulled to the uppermost end by the pull rod 23, thus realizing the folding action of the door body 10.

[0087] Reference can be made to Figure 3 and Figure 5 In one embodiment, the folding door 100 further includes a first fixing seat 231 and a second fixing seat 232. The first fixing seat 231 is disposed on the first beam 21, and the second fixing seat 232 is disposed on the second door panel 12. One end of the pull rod 23 is rotatably connected to the first fixing seat 231, and the other end of the pull rod 23 is rotatably connected to the second fixing seat 232.

[0088] The connection manner between the pull rod 23 and the first fixing seat 231 can be screw connection, snap connection, etc. Specifically, the first fixing seat 231 may include a bottom plate and a fixing portion. The two fixing portions are oppositely disposed on the bottom plate to form a receiving space. A first connection hole is formed on the fixing portion, and a second connection hole is also formed on the base. A third connection hole is formed on the pull rod 23. When the pull rod 23 is connected to the first fixing seat 231, the third connection hole and the first connection hole are correspondingly disposed, and a bolt is provided to pass through the first connection hole and the third connection hole. At the same time, a bolt is provided to pass through the second mounting hole to realize the fixation of the first fixing seat 231 and the first beam 21. The first fixing seat 231 can be a metal member, a high-strength plastic member, etc., without limitation. Optionally, there are two first fixing seats 231, which are correspondingly disposed at two ends of the first beam 21 in the first direction.

[0089] Optionally, the first door panel 11 is connected to one end of the first fixing seat 231 away from the ground in the first direction, and the pull rod 23 is connected to one end of the first fixing seat 231 close to the ground in the first direction. Connecting the pull rod 23 and the first door panel 11 to the same first fixing seat 231 can reduce the use of connecting components while ensuring the connection strength.

[0090] A plurality of threaded holes are formed on the second fixing seat 232. Specifically, a plurality of countersunk head bolts are used to fix the pull rod 23 and the second fixing seat 232. Optionally, there are two second fixing seats 232, which are correspondingly disposed at the ends of the second door panel 12 in the first direction.

[0091] Using the first fixing seat 231 and the second fixing seat 232 to fix both ends of the pull rod 23 is beneficial to ensuring the force reliability and safety of the pull rod 23.

[0092] Reference can be made to Figure 3 and Figure 5In one embodiment, the folding door 100 further includes a hydraulic rod 24. One end of the hydraulic rod 24 is rotatably connected to the column 22, and the other end of the hydraulic rod 24 is rotatably connected to the first door panel 11.

[0093] Optionally, the hydraulic rod 24 can be manually driven or electrically driven. Specifically, the folding door 100 further includes a motor, which is electrically connected to the hydraulic rod 24 to achieve the electric drive of the hydraulic rod 24, enabling the folding door 100 to fold automatically. Using the electric hydraulic rod 24 to automatically open or close the folding door 100 is safer and more labor-saving. The hydraulic rod 24 is used in conjunction with the door tie rod lock 13. After the door tie rod lock 13 is activated, the hydraulic rod 24 opens the folding door 100.

[0094] The hydraulic rod 24, the tie rod 23, the first door panel 11, and the second door panel 12 form a four-bar mechanism to achieve the folding movement of the second door panel 12. Compared with the folding door 100 that uses a slide rail to limit the trajectory of the second door panel 12, the present utility model uses a four-bar mechanism to limit the trajectory of the second door panel 12, enabling the folding door 100 to be fully opened, which is more conducive to the product entering and exiting the container.

[0095] Optionally, there are two hydraulic rods 24, which are correspondingly connected to the first column 22 and the second column 22 respectively.

[0096] Specifically, when converting from the first state to the second state, the hydraulic rod 24 extends partially. At this time, the hydraulic rod 24 has a certain angle with the second direction, and the force of the hydraulic rod 24 is mainly used to overcome the gravity of the door body 10. The door body 10 is slowly pushed out. During the pushing process, due to the pulling force of the tie rod 23 on the second door panel 12 caused by the movement, the second door panel 12 folds as the first door panel 11 moves. When the first door panel 11 moves to the uppermost end, the second door panel 12 is also pulled to the uppermost end by the tie rod 23, thereby realizing the folding movement of the door body 10 to complete the full opening of the folding door 100.

[0097] For reference Figure 3 and Figure 5 In one embodiment, the folding door 100 further includes a first support member 241 and a second support member 242. The first support member 241 is disposed on the column 22, and the second support member 242 is disposed on the first door panel 11. One end of the hydraulic rod 24 is connected to the first support member 241, and the other end of the hydraulic rod 24 is connected to the second support member 242.

[0098] The connection manner between the first support member 241 and the column 22 and the connection manner between the second support member 242 and the first door panel 11 can be welding, bonding, screwing, etc., without limitation. The first support member 241 and the second support member 242 can be metal components, high-strength plastic components, etc.

[0099] Connecting the two ends of the hydraulic rod 24 using the first support member 241 and the second support member 242 is conducive to ensuring the working reliability and safety of the hydraulic rod 24.

[0100] For reference, Figure 3 and Figure 5 In one embodiment, in the projection of the folding door 100 in the extending direction of the first beam 21, the length of the pull rod 23 is d1, the distance from the connection between the first door panel 11 and the first beam 21 to the connection between the pull rod 23 and the first beam 21 is d2, the distance from the connection between the first door panel 11 and the second door panel 12 to the connection between the pull rod 23 and the second door panel 12 is d3, and the dimension from the first end 111 to the second end 112 of the first door panel 11 is h1, satisfying: d1 + d2 > h1 + d3.

[0101] Specifically, when the first door panel 11 and the pull rod 23 are arranged on the same first fixing seat 231, d2 can be the distance from the rotating shaft of the connection between the first door panel 11 and the first fixing seat 231 to the rotating shaft of the connection between the pull rod 23 and the first fixing seat 231.

[0102] When d1 + d2 > h1 + d3, the pulling force generated by the movement of the pull rod 23 on the second door panel 12 can make the second door panel 12 fold along with the movement of the first door panel 11, realizing the folding action of the door body 10.

[0103] For reference, Figure 4 In one embodiment, the door body 10 further includes a second rubber strip 25, and the second rubber strip 25 is used to be arranged at the connection between the first door panel 11 and the first beam 21, and the second rubber strip 25 extends along the extending direction of the first beam 21.

[0104] The material of the second rubber strip 25 can be polyurethane, epoxy resin, polyethylene, silicone rubber, rubber, etc., without limitation.

[0105] Optionally, the folding door 100 further includes a connecting member 251, and the connecting member 251 is arranged on the side of the first end 111 of the first door panel 11 facing the door frame 20. The connecting member 251 is in an "L" shape. One end of the connecting member 251 is connected to the first door panel 11, and the other end of the connecting member 251 is connected to the second rubber strip 25. The connection method between the connecting member 251 and the second rubber strip 25 can be snap connection.

[0106] Using the connecting member 251 to cooperate with the first door panel 11 makes the installation of the second rubber strip 25 more firm, which is conducive to extending the service life of the second rubber strip 25.

[0107] For reference, Figure 4, In one embodiment, the door body 10 further includes a drainage member 27. The drainage member 27 is used to be arranged at the joint of the first door panel 11 and the first beam 21. The drainage member 27 is provided with a drainage groove 271. The opening of the drainage groove 271 faces the second rubber strip 25. Both the drainage member 27 and the drainage groove 271 extend along the extension direction of the first beam 21.

[0108] The drainage member 27 includes a first section 272, a second section 273 and a third section 274 which are connected in sequence. The first section 272 and the third section 274 extend along the second direction, and the second section 273 extends along the first direction. And both ends of the drainage groove 271 have no side walls in the first direction, which is a through design in the first direction, so that water can be discharged to the outside of the folding door 100 on both sides in the first direction. The drainage member 27 can be an aluminum-plastic pipe, a polyvinyl chloride pipe, a polyethylene pipe, etc., without limitation. The bottom wall of the drainage groove 271 can be arc-shaped, rectangular, etc., without limitation.

[0109] The drainage member 27 encloses to form the drainage groove 271, so that water is discharged from the inside of the folding door 100. At the same time, it can also prevent water from continuing to seep into the ground inside the folding door 100, damaging the sealing performance and service life of the folding door 100.

[0110] For reference Figure 4 , In one embodiment, the door body 10 further includes a water guide piece 26. The water guide piece 26 is arranged between the second rubber strip 25 and the drainage member 27. The water guide piece 26 is adapted to guide the water seeping from the second rubber strip 25 into the drainage groove 271.

[0111] The water guide piece 26 is connected to the first door panel 11. The water guide piece 26 is closer to the ground than the second rubber strip 25. There is an included angle between the water guide piece 26 and the first door panel 11. The water guide piece 26 extends along the direction close to the ground. The water guide piece 26 can be a plastic member, a stainless steel member, an aluminum alloy member, etc. The connection manner between the water guide piece 26 and the first door panel 11 can be welding, bonding, screwing, etc., without limitation. The water guide piece 26 can be multiple. The multiple water guide pieces 26 are arranged at intervals in the first direction. When the water guide piece 26 is one, the water guide piece 26 extends along the first direction. After the second rubber strip 25 fails or leaks, the water guide piece 26 mainly plays a guiding role for the leaked water, so that the water can enter the drainage groove 271 and does not affect the other components of the folding door 100.

[0112] When the second rubber strip 25 fails or leaks, the flowing water flows through the water guide piece 26 into the drainage groove 271 formed by the drainage member 27. The top of the drainage groove 271 is an open structure, which can be used to drain water to the outside of the container in the first direction, which is beneficial to improving the waterproof effect of the folding door 100 and the container.
