[0006] In view of this, the utility model provides an impact-resistant protective closed door, comprising: a door frame, a closed door is hingedly connected to one side of the door frame, a hollow groove is provided inside the closed door, and a protective door is slidably connected in the hollow groove, characterized in that it also includes:

[0007] A buffer assembly, wherein the buffer assembly is disposed in the hollow groove and between the protective door and the bottom of the hollow groove;

[0008] A sealing component, the sealing component is used to seal the door and the door frame tightly;

[0009] Wherein, the sealing component is arranged on a side away from the door frame and connected to the sealed door hinge.

[0010] In the above technical solution, further, a sealing strip is provided on the inner side surface of the door frame, and a groove matching the sealing strip is provided on the outer side surface of the closed door.

[0011] In the technical solution, a sealing strip is provided on the inner side of the door frame and a groove matching the sealing strip is provided on the outer side of the sealed door, thereby improving the sealing effect of the sealed door.

[0012] In the above technical solution, further, the sealing component includes:

[0013] A mounting seat, one end of which is connected to the door frame, and the other end of which is rotatably connected to a fixing column, the top of which is fixedly connected to a rotating disk, and a threaded groove is provided on the rotating disk;

[0014] A first threaded rod, wherein a pressing plate is fixedly connected to the lower end of the first threaded rod, and a handle is connected to the upper end of the first threaded rod;

[0015] Wherein, the first threaded rod is threadedly connected to the thread groove.

[0016] In the present technical solution, after closing the sealed door, the user rotates the rotating disk through the rotation cooperation of the mounting base and the fixed column, so that the pressing plate rotates to the specified position, and turns the handle, and the first threaded rod moves downward, so that the pressing plate is tightly pressed against the sealed door, thereby making the sealed door close to the door frame. At the same time, a sealing strip is provided on the inner side of the door frame to fit closely with the groove of the sealed door, thereby greatly improving the sealing effect of protecting the sealed door.

[0017] In the above technical solution, further, the pressing plate is made of rubber material.

[0018] When the protective door is impacted, the pressing plate is made of rubber and can provide good elasticity and buffering performance.

[0019] In the above technical solution, further, two sealing components are provided and are symmetrically arranged on the outer surface of the door frame.

[0020] In the above technical solution, further, the buffer component includes:

[0021] A slide bar is vertically arranged, and the upper and lower ends of the slide bar are slidably connected to the hollow groove;

[0022] A plurality of spring plates, wherein the plurality of spring plates are sleeved and connected to the outer wall of the slide rod;

[0023] One side of the spring plate is fitted with the hollow groove, and the other side is fitted with the protective door.

[0024] In this technical solution, when the protective door moves due to impact, the buffer assembly can provide a buffer area to reduce the impact force. One side of the spring plate is in contact with the hollow groove, and the other side is in contact with the protective door. When the protective door moves into the hollow groove after being impacted, the spring plate contracts inward, thereby driving the sliding rod to move into the hollow groove, so that the spring plate absorbs part of the impact force.

[0028] Wherein, one end of the rack is fixedly connected to the protective plate.

[0029] In this technical solution, when the sealed door is impacted, the impact force is concentrated on the protective door, and the protective door moves inward, thereby driving the rack to move inward. Since the rack is meshingly connected with the gear, the gear is driven to rotate, and then the second threaded rod rotates, causing the counterweight to move upward, converting the impact force into an upward force on the counterweight, greatly improving the impact resistance of the protective sealed door.

[0030] In the above technical solution, further, the anti-impact components and the buffer components are each provided with two groups, the two groups of the anti-impact components and the buffer components are symmetrically arranged on both sides of the hollow groove, and the two groups of buffer components are located between the two groups of anti-impact components.

[0031] In this technical solution, with the cooperation of two groups of impact-resistant components and two groups of buffer components, the impact resistance of the protective closed door is greatly improved.

[0032] The beneficial effects of the utility model are:

[0033] 1. After closing the sealed door, the user rotates the rotating disk through the rotation cooperation of the mounting base and the fixed column, so that the pressing plate rotates to the specified position, and turns the handle, and the first threaded rod moves downward, so that the pressing plate is tightly pressed against the sealed door, thereby making the sealed door close to the door frame. At the same time, a sealing strip is provided on the inner side of the door frame to fit closely with the groove of the sealed door, thereby greatly improving the sealing effect of protecting the sealed door.

[0034] 2. When the closed door is impacted, the impact force is concentrated on the protective door, and the protective door moves inward, thereby driving the rack to move inward. Since the rack is meshed with the gear, the gear is driven to rotate, and then the second threaded rod rotates, so that the counterweight block moves upward, converting the impact force into an upward force on the counterweight block. At the same time, the buffer assembly can provide a buffer area to reduce the impact force. One side of the spring plate fits with the hollow groove, and the other side fits with the protective door. When the protective door moves into the hollow groove after being impacted, the spring plate shrinks inward, thereby driving the slide bar to move into the hollow groove, so that the spring plate absorbs part of the impact force. With the cooperation of the buffer assembly and the anti-impact assembly, the impact resistance of the protective closed door is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS
