DETAILED DESCRIPTION

[0022] See also Figure 1-6The utility model provides a spliced ​​roadbed slope protection structure, including a slope protection brick 1, a plurality of slope protection bricks 1, the four corners of the slope protection brick 1 are inclined, the middle position of the slope protection brick 1 is penetrated with a central opening 2, the top of the slope protection brick 1 is fixed with a cross-shaped connecting plate 3, two adjacent connecting plates 3 are fitted, an L-shaped inner bin 10 is provided inside the connecting plate 3, one end and one side of the inner cavity of the inner bin 10 are slidably inserted with a movable bar 11, one end and one side of the inner bin 10 are connected to the outside of the connecting plate 3, a contact plate 12 is fitted at the middle position of the two movable bars 11, the surface of the top of the connecting plate 3 is threadedly connected with a second threaded rod 13, the bottom of the second threaded rod 13 is rotatably connected to the surface of the top of the contact plate 12, and the connecting plate A slot 20 is provided at one end and one side of the surface of 3, and two shaft grooves 16 are connected at the bottom of the inner bin 10. A limit shaft 17 is fixed inside the shaft groove 16, and a shaft sleeve 18 is provided on the outer peripheral surface of the limit shaft 17. The top of the shaft sleeve 18 is fixed to the surface of the bottom of the movable bar 11 at the adjacent position. By placing a plurality of slope protection bricks 1 in a close relationship so that the connecting plates 3 between each other can be in close relationship, the movable bar 11 inside one of the connecting plates 3 can be aligned with the slot 20 on the surface of another connecting plate 3, so that the second threaded rod 13 is rotated so that the movable bar 11 can be embedded in the slot 20 at the adjacent position, so that the adjacent slope protection bricks 1 can be prevented from separating under the interference between the movable bar 11 and the slot 20, thereby realizing the splicing connection setting between the plurality of slope protection bricks 1.

[0023] Further as Figure 5 and Figure 6 As shown, it is worth explaining in detail that a spring 19 is sleeved on the outer circumferential surface of the limit shaft 17 near the adjacent position sleeve 18, the spring 19 is fixed to the surface of the sleeve 18 near the adjacent position sleeve 18, and the spring 19 is fixed to the inner cavity surface of the shaft groove 16 away from the adjacent position sleeve 18. Due to the connection setting of the spring 19, when the contact plate 12 moves vertically downward and contacts one side or one end of the movable bar 11 detaches from the interior of the connecting plate 3, the sleeve 18 can contact the adjacent position spring 19 to cause it to deform, so that under the action of the rebound force of the spring 19, the movable bar 11 can automatically embed back into the interior of the connecting plate 3 when the contact plate 12 moves vertically upward.

[0024] Further as Figure 1 and Figure 3As shown, it is worth explaining in detail that an insert block 6 is inserted in the middle position of four adjacent slope protection bricks 1, and two positioning grooves 4 are provided at the four corners of the slope protection brick 1. A positioning plate 5 is inserted in the positioning groove 4, and one end of the positioning plate 5 passes through the adjacent positioning groove 4 and is fixed to the surface of the adjacent insert block 6. A first threaded rod 7 is threadedly connected through the middle position of the insert block 6. By inserting the insert block 6 into the cavity formed at the four corners of the four adjacent slope protection bricks 1, the positioning plate 5 can be inserted into the positioning groove 4 during this process, so that the adjacent slope protection bricks 1 can be limited under the interference between the positioning groove 4 and the positioning plate 5, and by rotating the first threaded rod 7, the first threaded rod 7 can extend to the bottom of the insert block 6 under the action of the threaded structure, thereby the bottom of the first threaded rod 7 can be embedded in the soil of the roadbed slope to limit and reinforce the slope protection brick 1.

[0025] Further as Figure 3 As shown, it is worth explaining in detail that a ground-inserting shaft 8 is fixed to the bottom of the first threaded rod 7, the surface of the bottom of the ground-inserting shaft 8 is conical, and the outer circumferential surface of the ground-inserting shaft 8 is evenly fixed with multiple groups of protrusions 9 that are equidistantly distributed. The shape of the bottom of the ground-inserting shaft 8 is convenient for embedding the ground-inserting shaft 8 into the soil, and when the ground-inserting shaft 8 is embedded in the soil, the protrusions 9 improve the firmness of the ground-inserting shaft 8 embedded in the soil.

[0026] The present solution has the following working process: in actual use, when the user needs to assemble multiple slope protection bricks 1 by splicing them together, the slope protection bricks 1 are placed in close contact with each other and the adjacent connecting plates 3 are in close contact with each other. The movable bar 11 inside the connecting plate 3 can be aligned with the slot 20 on the surface of another connecting plate 3. Then, the second threaded rod 13 is rotated to extend vertically downward under the cooperation of the threaded structure between the second threaded rod 13 and the connecting plate 3, so that the contact plate 12 can only move vertically downward under the contact limit of the inner bin 10, so that the inclined surface at the bottom of the contact plate 12 The inclined surface position of the two movable bars 11 can be resisted. Since the shaft sleeve 18 can only slide along the outer peripheral surface of the limiting shaft 17 in the inner cavity of the shaft groove 16 to limit the movement trajectory of the movable bar 11 at the adjacent position, the movable bar 11 can be separated from the inside of the connecting plate 3 at the position close to the adjacent position slot 20 and extend to the inside of the adjacent position slot 20, so that the multiple connecting plates 3 cannot be separated from each other, so that the assembly and splicing of the slope protection brick 1 can be realized. When disassembly is required, due to the connection setting of the spring 19, the vertical downward movement of the resisting plate 12 When the movement contacts one side of the movable bar 11 and one end is separated from the interior of the connecting plate 3, the sleeve 18 can contact the adjacent spring 19 to deform it, so that under the action of the spring 19, when the second threaded rod 13 is rotated in the opposite direction, the movable bar 11 can automatically be inserted back into the interior of the connecting plate 3 when the contact plate 12 moves vertically upward. Therefore, it is not necessary to adopt the traditional integrated design to replace the local damaged position separately. By inserting the insert block 6 into the cavity formed at the four corners of the four adjacent slope protection bricks 1, the positioning plate 5 can be inserted in the process. The interior of the positioning groove 4 can limit the adjacent slope protection bricks 1 under the interference of the positioning groove 4 and the positioning plate 5, and by rotating the first threaded rod 7, the first threaded rod 7 can extend to the bottom of the plug block 6 under the action of the threaded structure, thereby the bottom of the first threaded rod 7 can be embedded in the soil of the roadbed slope to limit and reinforce the slope protection bricks 1. The shape setting of the bottom of the ground insertion shaft 8 makes it easy to embed the ground insertion shaft 8 into the soil. When the ground insertion shaft 8 is embedded in the soil, the firmness of the ground insertion shaft 8 embedded in the soil is improved under the action of the protrusion 9.

[0027] According to the above working process, it can be known that: by placing multiple slope protection bricks 1 in a close relationship so that the connecting plates 3 between them can fit together, the movable bar 11 inside one of the connecting plates 3 can be aligned with the slot 20 on the surface of another connecting plate 3, so that when the second threaded rod 13 is rotated, the movable bar 11 can be embedded in the slot 20 at the adjacent position, so that the adjacent slope protection bricks 1 can be prevented from separating due to the interference between the movable bar 11 and the slot 20, thereby realizing a splicing connection setting between multiple slope protection bricks 1, without the need to adopt a traditional integrated design, and thus the installation method can replace one of the slope protection bricks 1 separately, thereby reducing waste and improving the practicality of the device, and inserting the plug 6 into the cavity formed at the four corners of four adjacent slope protection bricks 1, and then through the interference between the positioning groove 4 and the positioning plate 5 and the bottom of the first threaded rod 7 being embedded in the soil at the installation position, the stability of the multiple slope protection bricks 1 installed on the roadbed slope when spliced ​​with each other can be improved, thereby improving the protection effect.

[0028] Further as Figure 6 As shown, it is worth explaining in detail that one side of the inner bin 10 is connected with a guide groove 14, and a guide block 15 is slidably inserted inside the guide groove 14. One side of the guide block 15 passes through the guide groove 14 at an adjacent position and is fixed to the surface of the contact plate 12 at an adjacent position. Since the guide block 15 can only slide in the inner cavity of the shaft groove 16 along the vertical direction, it can limit the movement trajectory of the contact plate 12 and make its movement more stable.

[0029] In summary, when placing a plurality of slope protection bricks 1 closely together, the connecting plates 3 between them can be closely together, so that the movable bar 11 inside one of the connecting plates 3 can be aligned with the slot 20 on the surface of another connecting plate 3, so that when the second threaded rod 13 is rotated, the movable bar 11 can be embedded in the slot 20 at the adjacent position, so that the adjacent slope protection bricks 1 can be prevented from being separated under the interference of the movable bar 11 and the slot 20, thereby realizing the splicing connection setting between the plurality of slope protection bricks 1, without adopting the traditional integrated design, and thus the installation method can be separately installed on one of the slope protection bricks 1 Replacement can be carried out to reduce waste, thereby improving the practicality of the device. By inserting the plug block 6 into the cavity formed at the four corners of four adjacent slope protection bricks 1, and then through the interference between the positioning groove 4 and the positioning plate 5 and the bottom of the first threaded rod 7 being embedded in the soil at the installation position, the stability of multiple slope protection bricks 1 installed on the roadbed slope when spliced ​​with each other can be improved, thereby improving the protection effect. Since the guide block 15 can only slide in the inner cavity of the shaft groove 16 along the vertical direction, it can limit the movement trajectory of the interference plate 12 and make its movement more stable.
