[0023] Further as Figure 3 and Figure 4 As shown, it is worth explaining in detail that the tightening mechanism includes a movable rod 17 inserted into the surface of the L-shaped mounting rod 3, and both ends of the movable rod 17 are fixed with limiting plates 18. The outer surface of the movable rod 17 is movably sleeved with a spring 19, and the top end of the spring 19 is fixed to the surface of the L-shaped mounting rod 3, and the bottom end of the spring 19 is fixed to the surface of the limiting plate 18 at the lower end, and a pull rod 20 is fixed to the top surface of the limiting plate 18 at the upper end, and the bottom surface of the limiting plate 18 at the lower end is in contact with the top surface of the sealing box 2.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the suspension assembly includes a snap ring 11 fixed to the surface of the ring 8, an arc-shaped protrusion 12 is fixed to one side of the top end of the rectangular rod 7, the arc-shaped protrusion 12 is clamped with the snap ring 11, the top end of the snap ring 11 is arc-shaped, and grip rods 9 are fixed to the upper ends of both sides of the rectangular rod 7. The grip rods 9 facilitate the overall movement of the base 1 and provide convenience for the operation of the staff; the snap ring 11 with an arc-shaped top is better squeezed with the arc-shaped protrusion 12, and the snap ring 11 is clamped on the arc-shaped protrusion 12.

[0025] Further as Figure 1 , Figure 3 and Figure 5 As shown, it is worth explaining in detail that limiting blocks 15 are fixed on both sides of the carrying box 13, and limiting grooves 5 are opened on both sides of the inner wall of the base 1 corresponding to the limiting blocks 15, and the carrying box 13 is limited by the limiting blocks 15 and the limiting grooves 5; rectangular through holes 21 are opened on both sides of the sealing box 2 corresponding to the limiting blocks 15.

[0026] Further as Figure 3As shown, it is worth explaining in detail that a rectangular groove is opened on one side of the carrying box 13, and a wrist ring 16 is rotatably connected to the inner wall of the rectangular groove. When the wrist ring 16 is not in use, the rectangular groove stores the wrist ring 16, and the wrist ring 16 is used to facilitate the holding of the carrying box 13; the sealing box 2 is away from the pull ring 4 matched with the rectangular rod 7, and the pull ring 4 facilitates the sliding of the sealing box 2; the top surface of the sealing box 2 is fixedly installed with an observation window 6, which is convenient for staff to observe through the observation window 6.

[0027] This solution has the following working process: In actual operation, the carrier box 13 is not tightly fitted to the box body, which may easily lead to radiation leakage. By placing the carrier box 13 in the base 1, wherein the limit block 15 is stuck in the limit slide groove 5, the carrier box 13 is limited to maintain the stability of the carrier box 13 in the base 1, and space is reserved for the installation of the sealed box 2. After the carrier box 13 is placed, the sealed box 2 is placed in the base 1, so that the sealed box 2 is stuck at the upper end of the carrier box 13, and the first sealing ring 14 on the top surface of the carrier box 13 is in contact with the inner top wall of the sealed box 2, and the second sealing ring 22 on the bottom surface of the sealed box 2 is in contact with the inner bottom wall of the base 1, thereby improving the stability of the carrier box 13. To ensure the sealing between 13 and the sealing box 2, after the cover is closed, by rotating the L-shaped mounting rod 3 to the vertical direction, the movable rod 17 is pushed downward under the elastic force of the spring 19, so that the limiting piece 18 at the lower end is against the top surface of the sealing box 2, thereby giving the sealing box 2 a downward force, so that the second sealing ring 22 fits more tightly with the inner wall of the base 1, and at the same time, the first sealing ring 14 fits more tightly with the inner top wall of the sealing box 2, further preventing radiation leakage. After the use of the device is over, the sealing box 2 is pulled up, so that the ring 8 moves up along the rectangular rod 7. When the sealing box 2 moves to the upper end of the base 1, the clamping ring 11 is clamped on the arc-shaped protrusion 12 to maintain the stability of the sealing box 2 after it is opened.

[0028] According to the above working process, it can be known that: by covering the carrying box 13 and the sealing box 2, and then by the mutual cooperation of the first sealing ring 14 and the second sealing ring 22, the sealing between the carrying box 13 and the sealing box 2 is improved, and finally by the setting of the tightening mechanism, a downward pressure is applied to the sealing box 2, so that the first sealing ring 14 and the second sealing ring 22 fit more tightly, thereby further improving the sealing between the carrying box 13 and the sealing box 2, and facilitating the operation of the staff.

[0029] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto.
