[0029] Referring to Figures 1 to 7 The utility model discloses a door sealing structure and a vault door, and makes the following embodiment:

[0030] A door sealing structure, comprising a lower door sill 100 and a lifting structure 200, the lifting structure 200, comprising two lifting blocks 210 respectively arranged at both ends of the lower door sill 100 and two lifting assemblies corresponding to the lifting blocks 210. When installing, the lower door sill 100 is slidably arranged on the ground, referring to Figure 6 When the door leaf 400 is in the open state, the lower door sill 100 sinks to be flush with the ground under the action of gravity, and at this time, the ground is flat, and when the door leaf 400 is closed, referring to Figure 5 The lifting assembly lifts the lower door sill 100, seals the gap between the door leaf 400 and the ground, plays a role of theft prevention and sealing, and the sealing effect here is achieved by shielding the bottom door joint of the lifting door sill; after the door leaf 400 is opened, the door sill 100 sinks to be flush with the ground under the action of gravity.

[0031] Specifically, the lower door sill 100 is installed on the ground, the lower door sill 100 can move up and down relative to the ground, the middle of the lower door sill 100 is provided with a counterweight, the counterweight increases the weight of the lower door sill 100, so that the lower door sinks to be flush with the ground under the action of gravity, the sealing effect of the utility model is achieved by shielding the bottom door joint of the lifting door sill, and the contact surface of the lower door sill 100 and the door can be provided with a rubber layer, so that the sealing effect is further improved.

[0032] The lifting structure 200 comprises two lifting blocks 210 and two lifting assemblies corresponding to the lifting blocks 210, and the two lifting blocks 210 are arranged at both ends of the lower door sill 100 and cooperate with the lifting structure 200 to lift the lower door sill 100.

[0033] The lifting assembly comprises a lifting fork 220, a lifting shaft 250, a first mounting seat 230 and a second mounting seat 240.

[0034] The first mounting seat 230 is installed on the ground close to the inner side of the door frame 300, referring to Figure 7The first mounting seat 230 is provided with a mounting groove 231 extending left and right, and the mounting groove 231 is provided with a connecting shaft 232 extending front and back. The lifting fork 220 includes two toggle rods arranged at an angle, and a rotating hole 221 is provided at the connection between the two toggle rods. The connecting shaft 232 passes through the left side wall of the mounting groove 231, the rotating hole 221, and the right side wall of the mounting groove 231 in sequence to fix the lifting fork 220 to the first mounting seat 230. The lifting fork 220 can swing around the connecting shaft 232. In this embodiment, the swing amplitude is about 25 degrees.

[0035] One end of the lifting fork 220 is engaged with the lifting block 210, and the other end of the lifting fork 220 is in contact with the lifting shaft 250. A clamping groove 211 is provided on one side of the lifting block 210 close to the lifting fork 220, and the toggle rod is movably engaged with the clamping groove 211.

[0036] In order to achieve a certain anti-loss effect, refer to Figure 1 As shown, the toggle lever is provided with an anti-slip protrusion 222 at the position where it is engaged with the engaging groove 211. One end of the lifting fork 220 is engaged with the lifting block 210, and the other end of the lifting fork 220 is in contact with the lifting shaft 250. The abutting surface of the toggle lever and the lifting shaft 250 is an arcuate surface 223, and the cross-section of the lifting shaft 250 is also blunt. When the toggle lever swings and abuts against the lifting shaft 250, the design of the arcuate surface 223 makes the contact between the two closer and more uniform. The design of the arcuate surface 223 allows the toggle lever to more flexibly adapt to swings of different angles. No matter at what angle the toggle lever swings, it can maintain stable contact and abutment with the lifting shaft 250.

[0037] Reference Figure 1 The second mounting seat 240 is arranged on the inner side of the door frame 300 column. The second mounting seat 240 is provided with a guide sleeve 241. The sliding sleeve of the lifting shaft 250 is arranged on the guide sleeve 241. The lifting shaft 250 is provided with an abutting portion 251 that abuts against the end of the left end of the guide sleeve 241. The abutting portion 251 is an abutting block or an annular step. The provision of the annular step can make the abutting force of the lifting shaft 250 uniform and improve the structural stability. One end of the lifting shaft 250 abuts against the lifting shaft 250. When the door leaf 400 is closed, the other end of the lifting shaft 250 abuts against the door leaf 400. The door sealing structure of the utility model is made of stainless steel, which has the advantages of being not easy to corrode and having high structural strength.

[0038] Specific working principle: During installation, the lower threshold 100 slides up and down and is set on the ground. When the door leaf 400 is in the open state, the lower threshold 100 sinks to the ground level under the action of gravity. At this time, the ground is flat and the pulley of the trolley can pass smoothly, which is convenient for transportation and can also protect the threshold and sealing mechanism. Figure 1When the door leaf 400 is closed, the lifting shaft 250 is moved to the left by the door leaf 400, and the left end of the lifting shaft 250 drives the lifting fork 220 to swing to the left, and the lifting fork 220 drives the lifting block 210 to lift the lower threshold 100 when swinging, seals the gap between the door leaf 400 and the ground, and plays a role of theft prevention and sealing; when the door leaf 400 is opened, the threshold 100 is sunk to be flush with the ground under the action of gravity, the lifting block 210 is lowered to return to the original position, the lever is swung back to the original position, and the lifting shaft 250 is also slid to the right to reset due to lack of resistance. The utility model can effectively prevent theft and seal while keeping the ground flat, facilitating the movement of the trolley.

[0039] With reference to Figure 2 and Figure 3 The utility model also provides a vault door which comprises the door sealing structure of any one of the above, a door frame 300, the second mounting seat 240 of the sealing structure is arranged on the side surface of the door frame 300, and the first mounting seat 230 is arranged on the ground. The vault door can effectively prevent theft and seal while keeping the ground flat, facilitating the movement of the trolley. In order to improve the sealing effect, the door frame 300 is provided with an upper threshold, and the upper threshold is provided with a sealing strip abutting against the door leaf 400, thereby playing a sealing effect. When the trolley enters or exits the vault, the trolley does not need to be lifted, which not only reduces the complexity of operation, but also protects the threshold and the sealing mechanism, improves the overall performance and safety of the vault door.

[0040] The preferred embodiments of the utility model are specifically described above, but the utility model is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model. The equivalent modifications or replacements are all included in the range defined by the claims of the application.
