Detailed ways

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

Please refer to Figures 1 to 5. In the embodiment of the utility model, a power lithium battery restraint tray includes a tray shell 1 and a battery body 2. A first base pad 3 and a second base pad 4 are fixed to the bottom of the inner wall of the tray shell 1. A partition is provided at the bottom of the inner wall of the tray shell 1 between the first base pad 3 and the second base pad 4, wherein the first base pad 3 is provided at the middle position of the second base pad 4, and a first through groove 5 is provided on the first base pad 3. A double threaded rod 6 is provided inside the first through groove 5 for horizontal rotation. A movable block 7 is provided on the first through groove 5 for movement. The threaded adjustment block 7 is at a position corresponding to the threaded position on the surface of the double-threaded rod 6. The number of second base pads 4 is greater than one. The outermost second base pad 4 of the second base pads 4 greater than one and close to the tray shell 1 is provided with a third through groove 22. A guide block 23 and a guide rod 24 are provided inside the third through groove 22. The guide block 23 is movably sleeved on the surface of the guide rod 24 to position the side panel 8 to avoid deflection of the side panel 8 during movement and affect the adjustment of the side panel 8. The side panel 8 is fixed on the top of the movable block 7, and the bottom of the side panel 8 is fixed to the top of the guide block 23.

A docking plate 9 is provided between the side panels 8, and the docking plate 9 is used to connect and fix the side panels 8. When the middle side panel 8 moves through the movable block 7, it will drive the other side panels 8 to move. A movable through groove 10 is provided on the surface of the side panel 8, and a slider 11 is movable inside the movable through groove 10. A spring A111 is provided at the bottom of the slider 11. The spring A111 moves inside the movable through groove 10 and the bottom end of the spring A111 is movably connected to the bottom of the inner wall of the movable through groove 10. A thin rod 25 is movable between the side panels 8 and inside the movable through groove 10. The slider 11 is fixed to the surface of the thin rod 25. A fixing bolt 12 is provided at the bottom of the side panel 8. The bottom end of the fixing bolt 12 passes through the side panel 8 and extends to the inside of the movable through groove 10 and is movably connected to the top of the slider 11. The fixing bolt 12 is mainly used to position the slider 11 at the bottom of the slider 11, and the effect of the spring A111 can be very good. The slider 11 is pushed downward. After the battery body 2 is placed between the side plates 8, the double-threaded rod 6 needs to be rotated to drive the movable blocks 7 to approach each other. The reason why the double-threaded rod 6 can make the two movable blocks 7 approach and move away from each other is that the double-threaded rod 6 has two sets of opposite threads. After the double-threaded rod 6 is rotated, the two sets of movable blocks 7 will move away from and approach each other. Combined with Figure 1, it can be seen that the setting position between the double-threaded rods 6, the two sets of movable blocks 7 are close to each other and fit on the side of the battery body 2 to position the battery body 2, and then the fixing bolt 12 is rotated to squeeze the slider 11 downward. The slider 11 moves downward and drives the sliders 11 at other positions to move downward through the thin rod 25. The thin rod 25 moves downward and drives the buckle rod 13 to move downward and tightly clamped on the top of the battery body 2. In this way, the battery bodies 2 with the same thickness and different sizes can be positioned, thereby improving the practicality of the tray shell 1.

The surface of the thin rod 25 is located between the two groups of side plates 8 and is rotatably sleeved with a snap rod 13. The number of the snap rods 13 matches the number of the battery bodies 2. A rotating rod 14 is fixed to the side of the snap rod 13 close to the tray shell 1. A connecting plate 15 is fixed to the other end of the rotating rod 14. A threaded hole 16 is provided on the connecting plate 15 for stabilizing the connecting plate 15 through a positioning screw 181. A vertical through groove 17 is provided on the side of the tray shell 1. A positioning structure 18 is movably provided inside the vertical through groove 17. The positioning structure 18 includes a positioning screw 181 and a fixing nut 182. The fixing nut 182 is movably sleeved on the surface of the positioning screw 181 and one side of the fixing nut 182 is movably connected to the surface of the tray shell 1. The positioning screw 181 passes through the vertical through groove 17 and is threadedly connected to the inner wall of the threaded hole 16. A spring B19 is fixed to the side of the connecting plate 15 close to the side plate 8. The spring B1 A positioning block 20 is fixed at one end close to the side plate 8, and a vertical positioning groove 21 is provided on the surface of the side plate 8 corresponding to the positioning block 20. The positioning block 20 slides inside the vertical positioning groove 21, and the battery body 2 moves on the opposite surface of the side plate 8, and the buckle rod 13 is buckled at the top of the battery body 2. In order to prevent the buckle rod 13 from rotating, after the operation of the buckle rod 13 is completed, it is necessary to use a positioning screw 181 to pass through the vertical through groove 17 and connect with the threaded hole 16 to position the connecting plate 15. The connecting plate 15 is stably fitted on the tray shell 1 by the spring B19 and then positioned by the positioning screw 181, and then the fixing nut 182 is rotated to make it fit on the surface of the tray shell 1, as shown in FIG. 1. In this way, the connecting plate 15 is positioned by the positioning screw 181 and cannot be rotated. When it is necessary to rotate the buckle rod 13, it is only necessary to remove the positioning screw 181 from the threaded hole 16 to make the buckle rod 13 rotate, so that the battery body 2 can be removed easily.
