[0002] The cage is a vertical transportation tool used in manufacturing companies or construction sites to transport people or goods up and down. The floor door is one of the structures of the cage. The floor door can be opened and closed laterally or longitudinally to open or close the cage, making it easier for people or goods to enter and exit the cage.

[0003] When the cage transports people or goods to high altitudes, the landing door is easily shaken by the air flow at high altitudes. In the prior art, the landing door of the cage generally uses a travel switch or an infrared sensor to determine whether the landing door of the cage is completely closed. The shaking of the landing door caused by the air flow is easy to temporarily disengage the switch or cause the infrared reflection signal to deviate, so that the cage may mistakenly judge that the landing door is not completely closed and trigger an alarm.

[0018] Therefore, the utility model provides the following effects and / or advantages:

[0019] The present application cooperates with a movable box body and a fixed shell body. When the door body moves to a fully closed state, one side of the movable box body can be covered on the mounting seat, thereby shielding the first sensing element, so that the external system cannot read the first sensing element. At the same time, the movable box body exposes the second opening, so that the second sensing element can be read by the external system. Through this working principle, the closing state of the door body can be simply and conveniently obtained. Even in an environment with strong high-altitude airflow, when the door body is offset due to shaking, the first opening of the movable box body can still be well covered on the mounting seat, and the second opening can still be exposed, thereby ensuring that the corresponding signal for the door body closing can still be correctly output in the case of shaking.

[0029] A door body 1 and a door frame 2, wherein the door body 1 is provided with a connecting seat 301;

[0030] In this embodiment, there are two door bodies 1.

[0031] A first sensing element 4, a mounting seat 201 is provided at the bottom of the door frame 2, and the first sensing element 4 is provided on the mounting seat 201;

[0032] The shielding component 5 comprises a fixed shell 501, a movable box body 502, and an elastic member 503. The fixed shell 501 is arranged on the connecting seat 201, and the movable box body 502 is sleeved in the fixed shell 501. The elastic member 503 makes the movable box body 502 have a tendency to move toward the first sensing member 4. The movable box body 502 is provided with a first opening 5021 and a second opening 5022. The first opening 5021 faces the first sensing member 4, and the second opening 5022 faces upward. When the elastic member 503 is not squeezed, the second opening 5022 is blocked by the fixed shell 501. After the shielding component 5 abuts against the mounting seat 201 for movement, the movable box body 502 is covered by the first sensing member 4 and the mounting seat 201 through the first opening 5021. After the movable box body 502 moves away from the first sensing member 4, the elastic member 503 is squeezed to expose the second opening 5022.

[0033] The second sensing element 6 is disposed in the second opening 5022 .

At the same time, a first opening 5021 is set on one side of the movable box body 502, and a second opening 5022 is set on the other side of the movable box body 502. When the elastic member 503 is not compressed, the elastic member 503 pushes the movable box body 502 to one side, so that the fixed shell 501 blocks the second opening 5022. When the door body 1 is about to be completely closed, the elastic member 503 has not been compressed yet, the first opening 5021 covers the mounting seat 201, thereby covering the first sensing member 4 and blocking the second opening 5022; after the door body 1 is completely closed, the movable box body 502 moves to the other side, the elastic member 503 is compressed, the first opening 5021 still covers the mounting seat 201, and the second opening 5022 is exposed.

[0035] Furthermore, a guide rail is provided at the bottom of the door frame 2; a pulley is provided at the bottom of the door body 1, and the door body 1 is arranged on the door frame 2 through the cooperation of the pulley and the guide rail.

[0038] Furthermore, the first sensing element and the second sensing element are RFID tags, and the floor door is provided with an RFID reader.

[0039] Furthermore, the mounting base 201, the fixed shell 501, and the movable box body 502 are all made of metal. When the second opening 5022 is blocked by the fixed shell 501, the fixed shell 501 and the movable box body 502 form an electromagnetic shielding for the second sensing element 6. When the movable box body 502 is covered on the first sensing element 4 and the mounting base 201 through the first opening 5021, the movable box body 502 and the mounting base 201 form an electromagnetic shielding for the first sensing element 4.

[0040] Preferably, the door frame 2 is also made of metal.

[0041] In this embodiment, the first sensing element 4 and the second sensing element 6 are RFID tags, which can send out corresponding signals after receiving electromagnetic waves sent by an external RFID reader. Since the mounting base 201, the fixed shell 501, and the movable box 502 are all made of metal, the electromagnetic shielding can shield the electromagnetic waves, thereby making the first sensing element 4 or the second sensing element 6 unable to work.

[0042] This embodiment adopts manual door opening.
