[0001] The utility model relates to the technical field of refrigerated storage devices, in particular to a sealed warehouse door for a cold chain warehouse. Background Art

[0002] In the cold chain transportation of logistics, in order to insure the items to be transported, it is necessary to refrigerate and store the items to be transported in a warehouse.

[0003] In order to reduce the loss of cold air in the warehouse, it is usually necessary to set a sealing strip between the warehouse door and the door frame, and the sealing strip is squeezed by closing the warehouse door and the door frame, so as to ensure the sealing performance of the warehouse door.

[0004] However, only one sealing strip is set, and the external force for squeezing the sealing strip only comes from the door frame and the warehouse door. The sealing performance of the warehouse door is low, and it is easy to cause the loss of cold air in the warehouse, which will increase the energy consumption of the refrigeration operation in the cold chain warehouse. Content of the Utility Model

[0005] In view of the above problems, the utility model provides one, and its purpose is to improve the sealing performance of the cold storage warehouse door.

[0006] In order to achieve the above invention purpose, the technical scheme adopted by the utility model is as follows:

When the door frame and the warehouse door are closed, the first step and the second step are in clearance fit; wherein, the first step includes: a first sealing surface perpendicular to the warehouse door and a second sealing surface parallel to the warehouse door; the second step includes: a third sealing surface perpendicular to the warehouse door and a fourth sealing surface parallel to the warehouse door; a first sealing strip, which is arranged on the second sealing surface; a plurality of support components, which are slidably arranged in the second step; a driving component, which can drive the support components to slide linearly away from the geometric center of the second step and protrude from the third sealing surface, so as to squeeze the first sealing strip; a second sealing strip, which surrounds the support components and is arranged on the fourth sealing surface.

[0008] Further, the warehouse door further includes: a slider, which is arranged on the support component; a chute, which is fixed at an angle inclined to the length direction of the second step and is opened on the second step, and the slider is slidably placed in the chute; the driving component selects a hydraulic cylinder, which is arranged in the chute and is on one side of the slider close to the geometric center of the second step for pushing the slider; a return spring, which is arranged in the chute and is on one side of the slider away from the hydraulic cylinder.

[0009] Further, the warehouse door further includes: a clamping plate, which is detachably installed on the second step by screws and is on one side of the support component away from the second step.

[0010] Further, the bin door further includes: a control component and a storage battery. The control component, the storage battery, and the hydraulic cylinder are electrically connected to each other in pairs and are all embedded in the bin door.

[0011] Further, with the geometric center of the second step as the center, four support components are provided. The length direction and width direction of each support component are parallel to the length direction and width direction of the second step.

[0012] The beneficial effects of the present utility model are as follows: In the present utility model, when the bin door is in the closed state, the fourth sealing surface and the second sealing surface can squeeze the second sealing strip. By providing the second sealing strip, the bin door and the door frame can be sealed to prevent the loss of cold air. In addition, by driving the support component to slide linearly away from the geometric center of the second step through the driving component, the outer edge of the support component can protrude a certain distance from the third sealing surface, so as to squeeze the first sealing strip, thereby applying an additional extrusion external force to the first sealing strip, which can effectively reduce the leakage amount of cold air flowing into the second sealing strip, play an insurance role, improve the sealing performance between the bin door and the door frame, and reduce the energy consumption in the refrigeration work in the warehouse.

Detailed Embodiments

[0017] In order to better understand the above technical solutions, the following will describe the above technical solutions in detail in conjunction with the accompanying drawings of the specification and specific embodiments.

[0018] Refer to Figure 1 、 Figure 2 and Figure 3As shown in the figure, an embodiment of the present application discloses a sealed door for a cold storage warehouse, including: a first step 31 and a second step 32, which are respectively arranged on the door frame 2 and the door 1. When the door frame 2 and the door 1 are closed, the first step 31 and the second step 32 are in clearance fit; wherein, the first step 31 includes: a first sealing surface 311 perpendicular to the door 1 and a second sealing surface 312 parallel to the door 1; the second step 32 includes: a third sealing surface 321 perpendicular to the door 1 and a fourth sealing surface 322 parallel to the door 1; a first sealing strip 41 is arranged on the second sealing surface 312; a plurality of support components 5 are slidably arranged in the second step 32; a driving assembly can drive the support components 5 to slide linearly away from the geometric center of the second step 32 and protrude from the third sealing surface 321, so as to squeeze the first sealing strip 41; a second sealing strip 42 is arranged around the support components 5 on the fourth sealing surface 322.

[0019] In the present utility model, when the door 1 is in the closed state, the fourth sealing surface 322 and the second sealing surface 312 can squeeze the second sealing strip 42. By arranging the second sealing strip 42, the sealing between the door 1 and the door frame 2 can be prevented, and the loss of cold air can be prevented; in addition, by driving the support components 5 to slide linearly away from the geometric center of the second step 32 through the driving assembly, the outer edge of the support components 5 can protrude from the third sealing surface 321 by a certain distance, so as to squeeze the first sealing strip 41, thereby applying an additional extrusion external force to the first sealing strip 41, which can effectively reduce the leakage amount of cold air flowing into the second sealing strip 42, play an insurance role, improve the sealing performance between the door 1 and the door frame 2, and reduce the energy consumption in the refrigeration work in the warehouse.

[0020] Continue to refer to Figure 2 As shown in the figure, the door 1 further includes: a slider 51 arranged on the support component 5; a chute 52 is inclined at a fixed angle in the length direction of the second step 32 and is opened on the second step 32. The slider 51 is slidably placed in the chute 52; the driving assembly selects a hydraulic cylinder 6, which is arranged in the chute 52 and is on the side of the slider 51 close to the geometric center of the second step 32 for pushing the slider 51; a return spring 61 is arranged in the chute 52 and is on the side of the slider 51 away from the hydraulic cylinder 6.

[0021] Of course, the distance between the clamping plate 7 and the second step 32 is less than the thickness of the first sealing strip 41, and the gap between the clamping plate 7 and the second step 32 can also clamp the first sealing strip 41 to improve the sealing performance.

[0022] In this embodiment, the main body of the hydraulic cylinder 6 is fixedly arranged in the chute 52. By making the piston rod of the hydraulic cylinder 6 extend, the slider 51 can be pushed to slide along the chute 52 to squeeze the return spring 61, thereby driving the support component 5 to protrude from the third sealing surface 321.

[0023] It can be understood that when the bin door 1 needs to be opened, the piston rod of the hydraulic cylinder 6 makes a telescopic movement. Under the action of the reset spring 61 restoring its deformation, the reset spring 61 pushes the slider 51 to slide towards the direction close to the hydraulic cylinder 6, so that the support member 5 can be retracted into the third sealing surface 321, ensuring that the bin door 1 can be opened normally.

[0024] Continue to refer to Figure 1 As shown, the bin door 1 further includes: a clamping plate 7, which is detachably mounted on the second step 32 by screws and is located on the side of the support member 5 away from the second step 32. By providing the clamping plate 7, the support member 5 is clamped to improve the stability of the movement of the support member 5 during the sliding process.

[0025] Furthermore, the bin door 1 further includes: a control component 8 and a storage battery. The control component 8, the storage battery and the hydraulic cylinder 6 are electrically connected to each other in pairs and are all embedded in the bin door 1; the storage battery provides electrical energy to the control component 8, and the control component 8 transmits electrical signals to control the start and stop of the hydraulic cylinder 6. The staff can remotely control the start of the hydraulic cylinder 6 outside the bin door 1 to complete the extrusion work on the first sealing strip 41.

[0026] It can be understood that the staff can transmit electrical signals to the control component 8 through a wireless signal transmission method such as Bluetooth / 2.4G.

[0027] Continue to refer to Figure 3 As shown, with the geometric center of the second step 32 as the center, four support members 5 are provided. The length direction and width direction of each support member 5 are both parallel to the length direction and width direction of the second step 32; by pushing the support member 5 to move along the sliding groove 52, the support member 5 can protrude a certain distance along both the length direction and width direction of the second step 32, so as to extrude the first sealing strip 41.
