[0036] Reference Figure 1 , Figure 1 A schematic diagram of the structure of a warehouse door sealing strip provided in an embodiment of the present application.

[0037] On the one hand, an embodiment of the present application provides a warehouse door sealing strip, including:

[0038] The sealing strip body 1 comprises a sealing surface 11 and a supporting surface 12 which are arranged away from each other, and a plurality of arc-shaped sealing grooves 111 are arranged at intervals on the sealing surface 11;

[0039] A connecting strip 2, fixedly connected to the sealing strip body 1, and a projection of the connecting strip 2 toward a side close to the sealing strip body 1 is located between the sealing surface 11 and the supporting surface 12;

[0040] The door leaf sealing strip 3 is fixedly connected to the side of the connecting strip 2 away from the sealing strip body 1, and is used to be fixedly connected to the door leaf 6 of the warehouse door.

[0041] Exemplarily, the sealing strip body 1, the connecting strip 2 and the door leaf sealing strip 3 are all made of rubber material and connected together by one-piece molding. The door leaf sealing strip 3 has a long strip cross-section and is used to be connected to the warehouse door leaf 6 by tightening the end of the bolt. At the same time, the door leaf sealing strip 3 with reduced sealing performance can be easily replaced by tightening the end of the bolt.

[0042] The sealing strip body 1 forms a rectangular frame at the outer wall edge of the warehouse door leaf 6 by 90-degree vulcanization welding. The sealing strip body 1 is driven to protrude from the four edges of the warehouse door leaf 6. The sealing strip body 1 is used to fit with the inner side of the door frame 7 at the outer wall edge of the warehouse door leaf 6, which can prevent water vapor from entering the interior through the gap. The sealing surface 11 of the sealing strip body 1 is provided with a plurality of arc-shaped sealing grooves 111 arranged at intervals, thereby forming a labyrinth sealing structure. The sealing strip body 1 is connected to the door leaf sealing strip 3 by a connecting strip 2, and the connecting strip 2 extends along the setting direction of the sealing strip body 1, thereby forming a sealing surface 11 for isolating external water vapor, thereby ensuring the sealed environment formed by the warehouse door leaf 6.

[0043] The door leaf sealing strip 3 is fixedly connected to the outer wall edge of the warehouse door leaf 6 to form a ring, and the sealing strip main body 1 is deformed toward the outer wall of the warehouse door leaf 6. The sealing strip main body 1 fits with the inner side of the door frame 7 around the warehouse door leaf 6 through multiple arc-shaped sealing grooves 111 opened at the sealing surface 11. The connecting strip 2 is deformed and the connection effect between the sealing strip main body 1 and the door leaf sealing strip 3 is ensured. A sealed environment is formed by the warehouse door leaf 6, the door leaf sealing strip 3, the connecting strip 2 and the sealing strip main body 1 squeezed and fitted with the inner side of the door frame 7 around the warehouse door leaf 6. At the same time, the sealing strip main body 1 drives the connecting strip 2 to deform and fit closely with the door frame 7 on the side of the warehouse door leaf 6, thereby reducing the height of the threshold in the door frame 7 and ensuring the user's convenience of passage, thereby providing a warehouse door sealing environment with excellent sealing performance and a threshold-free structure.

[0044] In a possible implementation, the connecting strip 2 is in a broken line shape or a wavy line shape.

[0045] In order to facilitate the sealing strip main body 1 to extend toward the four sides of the warehouse door leaf 6 without causing damage to the connecting strip 2, the cross-section of the connecting strip 2 is set to a wavy line shape or a broken line shape, so as to effectively increase the length of the connecting strip 2, thereby ensuring that the connecting strip 2 is not damaged while following the movement of the sealing strip main body 1.

[0046] In a possible implementation, the sealing strip body 1 is provided with a cavity 14 .

[0047] In order to save the material cost of preparing the sealing strip body 1 and ensure that the sealing strip body 1 is tightly fitted with the inner side of the door frame 7 on the outer side of the warehouse door leaf 6 through deformation, a cavity 14 is provided in the sealing strip body 1. By providing the cavity 14, the material required for preparing the sealing strip body 1 can be reduced. At the same time, when the sealing surface 11 of the sealing strip body 1 is fitted with the inner wall of the door frame 7 around the outer wall of the warehouse door leaf 6, as the external force applied to the sealing strip body 1 continues to increase, the cavity 14 will gradually deform, and in this process, it is ensured that the sealing surface 11 of the sealing strip body 1 is always fitted with the inner wall of the door frame 7, thereby providing a stable sealing environment.

[0048] In a possible implementation, a fixing groove 13 is formed on an outer wall of the sealing strip body 1 adjacent to the supporting surface 12 , and a length direction of the fixing groove 13 is parallel to a length direction of the sealing strip body 1 .

[0049] During long-term use, the sealing strip body 1 needs to be expanded to the outside of the warehouse door leaf 6 through the transmission structure 5 arranged on the support surface 12. By opening a fixing groove 13 on the sealing strip body 1, the connection reliability between the sealing strip body 1 and the transmission structure 5 can be ensured, and the worn sealing strip body 1 and the transmission structure 5 can also be easily separated and replaced.

[0050] In a possible implementation, a cross-sectional area of ​​a side of the sealing strip body 1 close to the supporting surface 12 gradually decreases.

[0051] By gradually reducing the cross-sectional area of ​​the sealing strip body 1 on the side close to the support surface 12, a chamfer can be set at the outer edge of the support surface 12 of the sealing strip body 1. The chamfer can not only reduce the probability of material waste in preparing the sealing strip body 1, but also can be connected to the movable end of the transmission structure 5 through the inclined surface formed after the chamfer, thereby ensuring the efficiency of installing the sealing strip body 1.

[0052] Reference Figure 2 , Figure 3 and Figure 4 , Figure 2 A schematic diagram of a sealing structure in which a sealing strip for a warehouse door provided in an embodiment of the present application is arranged on the top edge of a door leaf of a warehouse door; Figure 3 for Figure 2 A magnified view of part A; Figure 4 A schematic diagram of the structure of the warehouse door leaf and supporting profile provided in an embodiment of the present application.

[0053] Based on the same inventive concept, the present application also provides a sealing structure, including the warehouse door sealing strip, the supporting profile 4 and the transmission structure 5 as described in the above technical solution;

[0054] The door leaf sealing strip 3 is used to be fixedly connected to the edge of the warehouse door leaf 6;

[0055] The support profile 4 is used to be slidably connected to the edge of the warehouse door leaf 6, and the sealing strip body 1 is fixedly connected to the support profile 4;

[0056] The transmission structure 5 includes a movable end for connecting to the supporting profile 4 , the movable end of the transmission structure 5 is fixedly connected to the supporting surface 12 of the supporting profile 4 , and the movable end of the transmission structure 5 is used to push the supporting profile 4 to protrude out of the outer wall edge of the warehouse door leaf 6 .

[0057] Exemplarily, the door leaf sealing strip 3 is connected to the warehouse door leaf 6 by tightening the ends of the bolts. At the same time, the door leaf sealing strip 3 with reduced sealing performance can be easily replaced by tightening the ends of the bolts.

[0058] The sealing strip body 1 forms a rectangular frame at the outer wall edge of the warehouse door leaf 6 by 90-degree vulcanization welding. The supporting surface 12 of the sealing strip body 1 fits with the supporting profile 4. The sealing strip body 1 is connected to the supporting profile 4 as a whole, and the supporting profile 4 is driven to move by the movable end of the transmission structure 5, thereby driving the sealing strip body 1 to protrude from the edges of the warehouse door leaf 6. The sealing strip body 1 is used to fit with the inner side of the door frame 7 around the warehouse door leaf 6, which can prevent water vapor from entering the interior through the gap. A labyrinth sealing structure for sealing water vapor is formed by opening a plurality of arc-shaped sealing grooves 111 arranged at intervals at the sealing surface 11 of the sealing strip body 1.

[0059] The supporting profile 4 is slidably arranged on the upper, lower, left and right side edges of the warehouse door leaf 6, and moves toward the side away from the warehouse door leaf 6 driven by the movable end of the transmission structure 5, thereby sealing the gap at the edge of the warehouse door leaf 6 and ensuring the airtightness of the formed sealed environment.

[0060] The transmission structure 5 can be implemented as a connecting rod structure or a gear rack structure. In the present embodiment, the transmission structure 5 is implemented as a gear rack structure. A hand wheel for the user to rotate is fixed to the gear by a coaxial connection. The axial direction of the gear is perpendicular to the plane where the warehouse door leaf 6 is located; there are at least four racks, each of which is meshed with the gear and can move toward the outer edge of the warehouse door leaf 6 under the drive of the gear. The rack is slidably connected to the warehouse door leaf 6, and the sliding directions of the two racks are horizontal, and the sliding directions of the other two racks are vertical. The side of the rack away from the gear is set as a movable end, which is used to be fixedly connected to the supporting profile 4, thereby driving the supporting profile 4 to protrude from the warehouse door leaf 6.

[0061] The sealing structure provided in the embodiment of the present application utilizes the warehouse door sealing strip, the supporting profile 4 and the transmission structure 5. The movable end of the transmission structure 5 drives the supporting profile 4 to move, thereby ensuring that the supporting profile 4 drives the warehouse door sealing strip to fit with the inner side of the door frame 7 on the outer side of the warehouse door leaf 6 to form a sealed environment, which can not only reduce the height required to set the threshold in the door frame 7, but also ensure the convenience of user passage.

[0062] In a possible implementation, a mounting groove 41 is provided at the supporting profile 4, the bottom wall of the mounting groove 41 is in contact with the supporting surface 12 of the sealing strip body 1, and the sealing strip body 1 is fixedly connected to the supporting profile 4 by mortise and tenon fixing.

[0063] The sealing strip body 1 extends into the mounting groove 41 of the supporting profile 4 after deformation and is connected by mortise and tenon fixing, thereby ensuring the convenience of connecting the sealing strip body 1 with the supporting profile 4. At the same time, by connecting the sealing strip body 1 and the mounting groove 41 of the supporting profile 4 as a whole by mortise and tenon connection, it can also ensure that the worn sealing strip is easily replaced.

[0064] In a possible implementation, a positioning bar 42 is fixedly connected to a side wall of the installation slot 41 close to its opening, and an outer wall of the positioning bar 42 away from an inner wall of the installation slot 41 is arc-shaped.

[0065] Exemplarily, the positioning bar 42 is fixedly connected to the inner wall of the installation slot 41 by integral molding, and the length direction of the positioning bar 42 is parallel to the opening direction of the installation slot 41 .

[0066] The outer wall of the positioning strip 42 is implemented as an arc, which can reduce the friction force encountered by the sealing strip body 1 when it extends into the installation groove 41. At the same time, the positioning strip 42 squeezes the sealing strip body 1 to deform it, thereby ensuring that the sealing strip body 1 is reliably connected to the installation groove 41 of the supporting profile 4, thereby reducing the probability of separation of the sealing strip body 1 and the supporting profile 4.

[0067] Reference Figure 1 On the other hand, the present application provides a warehouse door, including the sealing structure as described in the above technical solution.

[0068] Exemplarily, four supporting profiles 4 are provided, two horizontally arranged supporting profiles 4 are slidably connected to the upper and lower edges of the warehouse door leaf 6 at intervals, and slide in the vertical direction; the other two vertically arranged supporting profiles 4 are arranged at the left and right edges of the warehouse door leaf 6 at intervals, and can slide in the horizontal direction, thereby pushing the respectively connected sealing strip bodies 1 to move toward the outer wall protruding from the warehouse door leaf.

[0069] The warehouse door provided in the present application adopts a sealing structure formed by a warehouse door sealing strip, a supporting profile 4 and a transmission structure 5. Compared with the warehouse door sealing method disclosed in the prior art, the height of the door sill in the door frame required to ensure the sealing effect is reduced, the user's passage experience is optimized, and at the same time, a reliable sealing environment can be ensured.

[0070] On the other hand, the present application provides a sealing method, which is applicable to the warehouse door as described in the above technical solution, comprising the following steps:

[0071] The door leaf sealing strip 3 is fixedly connected to the door leaf 6 of the warehouse door;

[0072] The movable end of the transmission structure 5 pushes the sealing strip body 1 to protrude from the outer wall edge of the warehouse door leaf 6, and the sealing strip body 1 fits tightly against the inner wall of the warehouse door frame to form a sealing area. The interior space and the exterior space of the warehouse are isolated by the sequentially arranged warehouse door leaf 6, the door leaf sealing strip 3, the connecting strip 2 and the sealing strip body 1 that fits tightly against the inner side of the door frame around the warehouse door leaf 6.

[0073] The door leaf sealing strip 3 is fixedly connected to the outer wall edge of the warehouse door leaf 6 to form a ring, and the sealing strip main body 1 is deformed toward the outer wall of the warehouse door leaf 6. The sealing strip main body 1 fits with the inner side of the door frame 7 around the warehouse door leaf 6 through multiple arc-shaped sealing grooves 111 opened at the sealing surface 11. The connecting strip 2 is deformed and the connection effect between the sealing strip main body 1 and the door leaf sealing strip 3 is ensured. A sealed environment is formed by the warehouse door leaf 6, the door leaf sealing strip 3, the connecting strip 2 and the sealing strip main body 1 squeezed and fitted with the inner side of the door frame 7 around the warehouse door leaf 6. At the same time, the sealing strip main body 1 drives the connecting strip 2 to deform and fit closely with the door frame 7 on the side of the warehouse door leaf 6, thereby reducing the height of the threshold in the door frame 7 and ensuring the user's convenience of passage, thereby providing a warehouse door sealing environment with excellent sealing performance and a threshold-free structure.
