CONCRETE IMPLEMENTATION

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a leveling instrument for highway construction, including an instrument body 1, a connecting block 2 fixedly connected to the bottom of the instrument body 1, a U-shaped block 3 installed at the bottom of the connecting block 2, a support frame 4 installed at the bottom of the U-shaped block 3, insertion slots 5 on both sides of the connecting block 2, two slots 6 on the top of the U-shaped block 3, a through slot 7 on one side of the inner cavity of the slot 6, a baffle 8 fixedly connected inside the slot 6, an adjusting rod 9 slidably connected inside the baffle 8, an arc-shaped pushing block 10 fixedly connected to the bottom of the adjusting rod 9, and an arc-shaped force-bearing block 11 abutting one side of the arc-shaped pushing block 10. A plug rod 12 is fixedly connected to one side of the force-bearing block 11, and a return spring 13 is fixedly connected to one side of the arc-shaped force-bearing block 11. One side of the return spring 13 is fixedly connected to the inside of the slot 6. When the operator pulls the adjusting rod 9 upward, the adjusting rod 9 drives the arc-shaped pushing block 10 to move upward, releasing the pushing force on the arc-shaped force-bearing block 11. At this time, the return spring 13 will drive the arc-shaped force-bearing block 11 and the plug rod 12 to be quickly pulled out from the inside of the plug slot 5. Then, the connecting block 2 can be pulled out from the inside of the U-shaped block 3, thereby realizing the quick disassembly of the level instrument body 1, thus saving a lot of assembly time and improving the overall work efficiency.

[0021] Reference Figure 2 and Figure 4 As shown in this embodiment: the surface of the plug rod 12 is slidably connected to the inside of the plug groove 5, the outer diameter of the plug rod 12 is adapted to the inner diameter of the plug groove 5, and the outer diameter of the plug rod 12 is precisely adapted to the inner diameter of the plug groove 5, which effectively prevents the occurrence of loosening or falling off and improves the stability and reliability of the level in highway engineering construction.

[0022] Reference Figure 3 and Figure 5 As shown in this embodiment: both ends of the inner cavity of the slot 6 are provided with limiting grooves 14, and both ends of the arc-shaped force-bearing block 11 are fixedly connected with limiting blocks 15. By providing limiting grooves 14 at both ends of the inner cavity of the slot 6 and fixing limiting blocks 15 at both ends of the arc-shaped force-bearing block 11, the limiting blocks 15 can slide inside the limiting grooves 14, thereby limiting the arc-shaped force-bearing block 11 and effectively preventing the arc-shaped force-bearing block 11 from shifting or shaking during movement.

[0023] Reference Figure 4As shown in this embodiment: a movable hole 16 is provided at the bottom of the inner cavity of the U-shaped block 3. A telescopic rod 17 is fixedly connected to the bottom of the inner cavity of the movable hole 16. A push plate 18 is fixedly connected to the top of the telescopic rod 17. A push spring 19 is fixedly connected to the bottom of the push plate 18. The bottom of the push spring 19 is fixedly connected to the bottom of the inner cavity of the movable hole 16. When the plug rod 12 is pulled out from the inside of the plug slot 5 and the fixing relationship with the connecting block 2 is released, the push spring 19, the push plate 18 and the telescopic rod 17 work together to push the connecting block 2 upward, making the disassembly process of the connecting block 2 more convenient.

[0024] Reference Figure 3 As shown in this embodiment, multiple friction-enhancing pads 20 are fixedly connected to the bottom of the inner cavity of the U-shaped block 3. By fixing multiple friction-enhancing pads 20 to the bottom of the inner cavity of the U-shaped block 3, the friction between the U-shaped block 3 and the connecting block 2 is increased, further improving the stability of the connecting block 2 during use.

[0025] Reference Figure 2 Figure 1 As shown in this embodiment: multiple positioning grooves 21 are provided on both sides of the inner cavity of the U-shaped block 3, and multiple positioning blocks 22 are fixedly connected to both sides of the connecting block 2. The cooperative design of the positioning grooves 21 and the positioning blocks 22 can ensure that the connection between the connecting block 2 and the U-shaped block 3 is more stable and accurate. During the assembly process, the positioning blocks 22 can be accurately embedded into the positioning grooves 21, avoiding the deviation and loosening problems that may occur in the traditional connection method, thereby improving the stability and reliability of the entire structure.

[0026] Working principle: By pulling the adjusting rod 9 upwards, the operator moves the arc-shaped pushing block 10 upwards, releasing the pushing force on the arc-shaped force-bearing block 11. At this time, the return spring 13 will cause the arc-shaped force-bearing block 11 and the connecting rod 12 to be quickly pulled out from the inside of the connecting groove 5. Subsequently, the connecting block 2 can be pulled out from the inside of the U-shaped block 3, thereby realizing the rapid disassembly of the level instrument body 1, saving a lot of assembly time and improving the overall work efficiency. The outer diameter of the connecting rod 12 is precisely matched with the inner diameter of the connecting groove 5, effectively preventing loosening or falling off, and improving the stability and reliability of the level instrument in highway engineering construction. By opening limiting grooves 14 at both ends of the inner cavity of the groove 6, and fixing limiting blocks 15 at both ends of the arc-shaped force-bearing block 11, the limiting blocks 15 can slide inside the limiting grooves 14, which plays a role in limiting the arc-shaped force-bearing block 11. The positioning function effectively prevents the arc-shaped force-bearing block 11 from shifting or shaking during movement. When the plug rod 12 is pulled out from the inside of the plug groove 5 and the fixing relationship with the connecting block 2 is released, the thrust spring 19, in cooperation with the thrust plate 18 and the telescopic rod 17, can push the connecting block 2 upward, making the disassembly process of the connecting block 2 more convenient. By fixing multiple friction pads 20 to the bottom of the inner cavity of the U-shaped block 3, the friction between the U-shaped block 3 and the connecting block 2 is increased, further improving the stability of the connecting block 2 during use. The matching design of the positioning groove 21 and the positioning block 22 can ensure that the connection between the connecting block 2 and the U-shaped block 3 is more stable and accurate. During the assembly process, the positioning block 22 can be accurately embedded into the positioning groove 21, avoiding the deviation and loosening problems that may occur in the traditional connection method, thereby improving the stability and reliability of the entire structure.
