[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , a geogrid with a stretching device, comprising an embedded rod 5, a grid plate 1 and a plurality of grid openings arranged on the front of the grid plate, the embedded rod 5 is fixed to the back of the grid plate 1, a fixed ring 8 is fixedly sleeved on the embedded rod 5, used to improve the firmness between the embedded rod 5 and the grid plate 1, one side of the fixed ring 8 is fixedly connected to the back of the grid plate 1, a mounting block 2 is provided in the grid opening for mounting a clamping block 3, a connecting plate 4 corresponding to the grid opening is fixedly connected to the back of the grid plate 1 for supporting the mounting block 2, one end of the mounting block 2 passes through the grid opening and is fixedly connected to the connecting plate 4, and the surfaces of the connecting plate 4 and the push block 6 are coated with anti-rust paint to play a certain directional role;

[0023] In this embodiment, a push block 6 is slidably inserted on the back of the connecting plate 4 to drive the slider 9 to move. The end of the push block 6 away from the slider 9 is fixedly connected to a rubber pad 7 to prevent the push block 6 from being worn by friction with the ground. A slide groove is provided in the mounting block 2. One end of the push block 6 slides through the connecting plate 4 and the mounting block 2 in sequence and is fixedly connected to the slider 9 to drive the support block 11 to move. The slider 9 is slidably connected in the slide groove. A guide rod 10 is slidably inserted on the side of the slider 9 away from the push block 6 to keep the slider 9 moving in a straight line and prevent it from skewing. One end of the guide rod 10 penetrates the slider 9 and is fixedly connected to the inner side wall of the slide groove. There are four guide rods 10 distributed in a rectangular shape to further prevent the slider 9 from skewing.

[0024] In this embodiment, one end of the slider 9 away from the push block 6 is fixedly connected with a conical support block 11 for pushing the block 3 to move. Blocks 3 are provided on the four sides of the support block 11 for cooperating with the slots to tighten and stretch the grille plate 1. The four sides are upper and lower and left and right sides. The inner side wall of the grille opening is provided with slots corresponding to the blocks 3. The opposite ends of the four blocks 3 all slide through the mounting block 2. The end of the block 3 close to the support block 11 is provided with a chamfer for installing a roller 12. An arc groove is provided at the chamfer of the support block 11. The inner side wall of the arc groove is rollingly connected with the roller 12 for reducing the friction between the block 3 and the support block 11 and reducing the resistance when the block 11 is pushed. The two ends of the roller 12 are respectively rotatably connected to the inner side wall of the arc groove, and part of the roller 12 passes through the arc groove and abuts against the support block 11.

[0025] In this embodiment, a plurality of grooves are provided on one side of the slide groove away from the push block 6, and a ball 13 is rollingly connected to the inner side wall of the groove for reducing the resistance of the block 3 when it moves. Part of the ball 13 passes through the groove and abuts against the block 3. A storage groove is provided on one side of the slide groove away from the push block 6, and two connecting blocks 14 are provided in the storage groove for cooperating with a spring 15 to elastically stretch the block 3. A spring 15 is fixedly connected between the two connecting blocks 14 for elastically stretching the connecting block 15. One end of the two connecting blocks 14 passes through the storage groove and is fixedly connected to the two blocks 3 respectively.

[0026] In this embodiment, during the laying process, the grille plate 1 is laid on the ground, and the embedded rod 5 is pushed downward to insert into the soil, which plays a positioning role for the grille plate 1. When the grille plate 1 is pressed downward, the push block 7 will be driven to resist the ground, and the grille plate 1 will move in the direction of the slide groove under the influence of the downward pressure of the grille plate 1, and the slider 9 will be pushed to move by the push block 7, and the support block 11 will be driven to move by the slider 9, and the card block 3 will be pushed to move by the support block 11, so that the card block 3 moves into the card groove, thereby tightening and stretching the grille plate 1, so that the grille plate 1 is laid on the ground in a flat state. Since the support block 11 is conical, and the end of the card block 3 close to the support block 11 is chamfered, and a roller 12 is provided at the chamfer, therefore, the friction and resistance when the support block 11 pushes the card block 3 are small, which reduces the difficulty of the support block 11 pushing the card block 3 to move, and at the same time, the ball 13 is used to reduce the resistance of the card block 3 when moving, further reducing the difficulty of the support block 11 pushing the card block 3 to move.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
