A movable assembly 2 is provided on the side of the two columns 101 away from each other and on the inner side of the base 103.

[0033] The moving assembly 2 includes a moving support unit and a driving unit. When the moving support unit is in a vertical state, it is used to provide moving support for the passage door 1. When the moving support unit is in an inclined state, it is used to provide anti-tilt support for the passage door 1. The driving unit is used to adjust the vertical state and the inclined state of the moving support unit.

[0034] The mobile support unit includes a support frame 201 and a mobile wheel 202;

[0035] A receiving groove 109 is provided on one side of the two columns 101 away from each other and near the bottom. The top of the support frame 201 is rotatably connected to the inner side of the receiving groove 109 via a rotating shaft, and the moving wheel 202 is installed at the bottom of the support frame 201.

[0036] Two groups of storage slots 109, support frames 201, and moving wheels 202 are provided on one side of the column 101. When the four groups of support frames 201 are in an upright state, the bottom of the base 103 is off the ground, and the moving wheels 202 are used to realize the convenient state of the passage door 1;

[0037] When the four sets of support frames 201 are in an inclined state, the bottom of the base 103 is in contact with the ground, and the inclined support frames 201 and the moving wheels 202 are used to provide auxiliary anti-tilt support for the passage door 1;

[0038] The driving unit includes a second worm gear 203, a second worm 204, a transmission bevel gear 205, a horizontal rotation shaft 206, a linkage bevel gear 207, a first worm gear 208 and a first worm 209;

[0039] An upper groove 104 is formed on the top of the base 103, a horizontal transmission groove 107 is formed on the bottom of the base 103, and a vertical transmission groove 108 is formed on the side of the columns 101 away from each other. The vertical transmission groove 108 is located between the two receiving grooves 109 and is connected to the horizontal transmission groove 107;

[0040] The first worm 209 extends from the upper groove 104 into the horizontal transmission groove 107 and is rotatably connected to the base 103. The horizontal shaft 206 is rotatably mounted inside the horizontal transmission groove 107. The first worm wheel 208 is fixed to the middle portion of the outer side of the horizontal shaft 206 and meshes with the first worm 209.

[0041] The second worm gear 203 is fixed to the outside of the rotating shaft connected to the support frame 201 and is located inside the vertical transmission groove 108. The second worm 204 is rotatably mounted inside the vertical transmission groove 108. The transmission bevel gear 205 is fixed to the bottom end of the second worm 204. The linkage bevel gears 207 are symmetrically fixed on both sides of the horizontal rotating shaft 206 and mesh with the two transmission bevel gears 205 respectively.

[0042] When the first worm 209 is rotated, the support frame 201 is rotated through the transmission of the first worm wheel 208, the horizontal shaft 206, the linkage bevel gear 207, the horizontal shaft 206, the transmission bevel gear 205, the second worm 204, and the second worm wheel 203;

[0043] The bearing bases for providing rotation support for the horizontal shaft 206, the first worm 209 and the second worm 204 are respectively installed on the inner sides of the horizontal transmission groove 107 and the vertical transmission groove 108;

[0044] An upper cover plate 106 is rotatably mounted on the inner side of the upper groove 104 , and an anti-slip rubber pad 3 is fixed to the bottom of the base 103 .

[0045] In this embodiment, when the passage door 1 is in normal use, the base 103 is in direct contact with the ground via the anti-skid rubber pad 3 (it should be noted that the anti-skid rubber pad 3 can increase the anti-skid resistance between the base 103 and the ground, making the passage door 1 more stable). In addition, the two sets of support frames 201 on the two columns 101 are in an inclined state, and their moving wheels 202 are in contact with the ground, forming an "eight"-shaped structure as a whole. This provides anti-tilting support for the columns 101, making the passage door 1 more stable.

[0046] When the passage door 1 needs to be moved, the upper cover 106 can be opened, and the first worm 209 can be rotated by an external tool (it should be noted that a hole slot for inserting a tool is provided on the top of the first worm 209, for example, a hexagonal slot is provided on the top of the first worm 209, and a hexagonal wrench is used to rotate the first worm 209). The first worm 209 drives the first worm gear 208 to rotate, and the first worm gear 208 drives the horizontal shaft 206 to rotate, and the horizontal shaft 206 drives the two linked bevel gears 207 to rotate synchronously, and the two linked bevel gears 207 respectively drive the two transmission bevel gears 205 to rotate, and the transmission bevel gear 205 drives the second worm 20 4 rotates, the second worm gear 204 drives the second worm gear 203 to rotate, the second worm gear 203 drives the rotating shaft of the support frame 201 to rotate, and the rotating shaft drives the support frame 201 to rotate, and the rotation directions of the support frames 201 on the two columns 101 are opposite. When the support frame 201 rotates to a vertical state, the support frame 201 is stored in the storage groove 109. At this time, the moving wheel 202 is located below the base 103, and the bottom of its protective rubber pad 3 is separated from the ground. The four moving wheels 202 can be used to realize the movement operation of the passage door 1 (it should be noted that the moving wheels 202 on the two columns 101 are respectively fixed pulleys and universal pulleys, so as to realize the convenient movement of the passage door 1);

[0047] After the passage door 1 is moved to the designated position, the direction of the universal pulley is adjusted to be the same as that of the fixed pulley (i.e., the direction of the wheel is perpendicular to the column 101), and the first worm 209 can be rotated again to rotate the support frame 201 to an inclined state, so that the passage door 1 as a whole is lowered and fits the ground. The overall operation is simple and convenient.

[0048] Please refer to Figures 1 to 4 Detectors are installed inside the columns 101, and a storage bin 105 is provided at the bottom of the upper groove 104. The storage bin 105 and the horizontal transmission groove 107 are staggered. Counterweights, batteries, and controllers are installed inside the multiple storage bins 105. The batteries are electrically connected to the detectors and the display assembly 102 through wires and the controller.

[0049] In this embodiment, the battery can provide the detector and the display assembly 102 with an operating power source, so that the passage door 1 can be used in more occasions, and the counterweight block can provide a counterweight for the passage door 1 to make it more stable.

[0050] The upper cover plate 106 is used to provide foot support for people passing through, and the people standing on the upper cover plate 106 are detected through detectors (one or more detectors are installed inside the column 101, and these detectors can sense different types of nuclear radiation, such as alpha particles, beta particles and gamma rays). The detectors will interact with the nuclear radiation in the environment, causing changes in charge or energy. The instrument will measure these changes and then convert them into readable electrical signals or digital signals, and display them through the display component 102.

[0051] The above is only a preferred specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the scope of protection of the present invention.
