[0022] Embodiment
[0023] Please refer to Figures 1-4 As shown, the present utility model provides a combined tortoise car trailer board, which includes a car board 1. Two adjacent side surfaces of the car board 1 are provided with positioning grooves 4, and there are two positioning grooves 4, which are symmetrically arranged on this plane. Positioning blocks 6 are fixed on the other two surfaces of the car board 1. The positions of the positioning blocks 6 correspond to the positions of the positioning grooves 4 on the opposite side. After the positioning block 6 of another tortoise car is inserted into the positioning groove 4, the heights and left-right alignments of the upper planes of the two tortoise cars are the same;
[0024] As Figures 1-4 shown, a placement groove 10 is opened on the top surface of the car board 1. The placement groove 10 is located directly above the positioning groove 4. A slot 11 is opened inside the placement groove 10, and the slot 11 penetrates through the car board 1 and passes through the positioning groove 4. Limiting grooves 5 are opened on both sides of the positioning block 6. After the positioning block 6 is inserted into the positioning groove 4, the limiting groove 5 coincides with the slot 11;
[0025] As Figures 1-4 shown, a top board 8 is placed inside the placement groove 10. Two positioning strips 7 are fixed at the bottom end of the top board 8. The positioning strips 7 can be inserted into the inside of the slot 11. After the positioning block 6 is inserted into the positioning groove 4, the positioning strip 7 will be engaged with the limiting groove 5, so that the positioning block 6 cannot withdraw from the inside of the positioning groove 4. A first magnet 9 is inlaid at the center position of the top board 8, and a second magnet 12 is inlaid at the center position of the placement groove 10. The first magnet 9 and the second magnet 12 can be attracted together by magnetic force. In order to facilitate the removal of the top board 8, an arc surface 13 is opened at the edge of the placement groove 10, so as to facilitate the removal of the top board 8;
[0026] As Figures 1-4 shown, four holding grooves 2 are opened on the top surface of the car board 1. The holding grooves 2 are located at the four sides of the car board 1. The edges of the holding grooves 2 are provided with rounded corners. Universal wheels 3 are fixed at the bottom of the car board 1. The universal wheels 3 are provided with a braking structure;
[0027] Specific working principle:
[0028] When assembling multiple turtle carts, place the turtle carts on the ground, align the positioning block 6 on the long side with the positioning slot 4 on the long side of another turtle cart, push the positioning block 6 into the inside of the positioning slot 4, and then move the top plate 8 so that the positioning strip 7 below the top plate 8 is inserted into the inside of the slot 11. After the positioning strip 7 passes through the limiting slot 5, the first magnet 9 and the second magnet 12 are magnetically attracted, so that the position of the top plate 8 is fixed. In this way, multiple turtle carts are assembled, making multiple turtle carts a whole, and the connection parts are not easily detached, thus ensuring relatively stable transportation of the items on the turtle carts.
