The outer surface of the linkage block 9 is slidably connected to the inner wall of the slide groove 8. The side of the linkage block 9 away from the positioning block 3 is fixedly connected to the toggle key 10, and the side of the linkage block 9 close to the box body 1 is fixedly connected to the linkage arm 11.

[0024] The above solution is adopted: by setting the linkage block 9, when the toggle key 10 is toggled upward, it can drive the linkage block 9 to slide upward along the slide groove 8, so that the linkage block 9 drives the linkage arm 11 to move upward synchronously.

[0028] The above solution is adopted: by setting the rotating arms 13, the two linkage rods 12 move upward and squeeze the inner walls of the two linkage grooves 14 at the same time, driving the two rotating arms 13 to rotate relative to each other, so that the two rotating arms 13 can respectively drive the synchronous rotation of the two force arms 15.

[0029] refer to Figure 4 The tops of the two force-applying arms 15 are fixedly connected to the bottoms of the two rotating arms 13 close to one end thereof, and two moving arms 16 are respectively provided at the bottoms of the two force-applying arms 15 .

[0030] The above solution is adopted: by providing the force-applying arms 15 , the two force-applying arms 15 can respectively push the two movable arms 16 during the rotation process, thereby driving the two movable arms 16 to move away.

[0031] refer to Figure 4 The middle of the two movable arms 16 are respectively slidably connected to the outer surface of the horizontal rod 401, and the sides of the two movable arms 16 that are close to each other are respectively fitted with the sides of the bottoms of the two force-applying arms 15 that are away from each other. The sides of the two movable arms 16 that are away from each other are respectively fixedly connected to the limit springs 17, and the two limit springs 17 are both sleeved on the outer surface of the horizontal rod 401. The ends of the two limit springs 17 that are away from each other are respectively fixedly connected to the inner wall of the positioning groove 4, and the sides of the two movable arms 16 away from the box body 1 are respectively fixedly connected with fixed blocks 18.

[0032] The above solution is adopted: by setting up the movable arm 16, the two movable arms 16 are pushed by the force arm 15 respectively, slide away on the horizontal rod 401, and squeeze the two limit springs 17 respectively for compression, and the two movable arms 16 slide and then drive the two fixed blocks 18 to move away respectively.

[0033] refer to Figure 3 and Figure 4 The two fixing blocks 18 are respectively fixedly connected to the front and rear sides of the two moving arms 16 away from one end of the box body 1, and the ends of the two fixing blocks 18 close to each other are respectively inserted into the inner walls of the limiting grooves 701.

[0034] The above solution is adopted: by setting the fixing block 18, when the two fixing blocks 18 move away, they can respectively disengage from the limiting groove 701 to release the fixation of the limiting block 7, thereby releasing the fixed limit of the clamping plate 2, so that the clamping plate 2 can slide toward the middle of the inner wall of the box body 1.

[0035] The working principle of this utility model:

[0036] When in use, the box cover 102 is opened and the tested battery pack is placed in the box body 1, and then the toggle button 10 on one side is toggled upward to drive the linkage block 9 to slide up along the slide groove 8, and synchronously drive the linkage arm 11 to move up in the positioning groove 4, so that it drives the movement of the two linkage rods 12 at the same time. The two linkage rods 12 move upward and squeeze the inner walls of the two linkage grooves 14 at the same time, to drive the two rotating arms 13 to rotate relative to each other, and respectively drive the synchronous rotation of the two force arms 15. The two force arms 15 rotate and the lower ends are separated at the same time. The two movable arms 16 are pushed separately to slide away from each other in the horizontal direction on the horizontal rod 401, and the compression of the two limit springs 17 is squeezed respectively. The two movable arms 16 slide and drive the two fixed blocks 18 away from each other, so that the two fixed blocks 18 are separated from the limit grooves 701 respectively to release the fixed limit of the limit block 7, thereby releasing the fixed limit of the clamping plate 2. Then the tension spring 602 at the bottom pulls the corresponding movable block 601 to slide toward the middle in the movable groove 6, so that the clamping plate 2 can fit the surface of the battery pack. Repeat this operation to toggle the toggle button 10 on the other side to release the fixation of the other clamping plate 2 and slide it to fit the battery pack. In this way, the two clamping plates 2 can clamp the placed battery pack, and then cover the box cover 102 to complete the storage, and can cooperate with the moving wheel 101 at the bottom to operate. When taking out the battery pack, push the clamping plate 2 on one side toward the corresponding positioning block 3, and slide the moving block 601 in the moving groove 6 to drive the limit block 7 to align and insert it into the opening 301, and at the same time, the tension spring 602 is tightened. Stretching, the limit block 7 moves and squeezes the surfaces of the two fixed blocks 18 at the same time, causing them to move and drive the two movable arms 16 to slide away, to squeeze the two limit springs 17 to compress. When the limit block 7 is fully inserted into the opening 301, the two limit springs 17 push the two movable arms 16 to slide, driving the two fixed blocks 18 to move closer and be respectively inserted into the limit slots 701 to fix the limit block 7, thereby fixing the clamping plate 2, and then pushing the other clamping plate 2 and fixing it in the same way. Finally, the battery pack can be taken out.

[0037] To sum up: the radiation shielding box for testing new energy battery packs, through the coordinated work of the box body 1, the clamping plate 2, the positioning block 3, the positioning groove 4 and the limiting structure 5, solves the problem that when the radiation shielding box is used to store new energy battery packs, if the battery packs are not fixed, they may be shifted by vibration, transportation or other external factors, causing the battery packs to collide with other components inside the shielding box, thereby causing damage or safety hazards.
