Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] like Figure 1 and Figure 2 As shown, a highway corrugated guardrail splicing structure includes: a corrugated guardrail body 20, which is a conventional corrugated guardrail, as this is existing technology, and therefore will not be described in detail here.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the docking structure is set on the rear wall of the corrugated guard plate body 20 for assembly and installation with other corrugated guard plate bodies 20. The docking structure includes: a control rod 30, a rotating column 32, a locking block 34, a locking rod 35, and a slot 38. The control rod 30 is fixedly connected to one side of the rear wall of the corrugated guard plate body 20. The rotating column 32 is rotatably connected to the rear wall of the control rod 30. The locking block 34 is fixedly connected to the wall of the rotating column 32. The locking rod 35 is fixedly connected to the rear wall of the corrugated guard plate body 20 on the same side as the control rod 30. The slot 38 is opened on the side wall of the locking rod 35.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the control lever 30 and locking lever 35 are rods with isosceles triangular cross-sections of the same size. The rotating post 32 is cylindrical, and the locking block 34 is an L-shaped block with rounded outer corners. Threaded grooves are formed through the walls of the locking block 34 and the rotating post 32. The locking groove 38 is an L-shaped groove that can fit the size of the locking block 34. The locking lever 35 is symmetrical to the control lever 30. The docking structure also includes a receiving groove 31, a lever 33, a through groove 36, and a stud 37. The receiving groove 31 is formed on the rear wall of the control lever 30, and the rotating post 32 is rotatably connected to the receiving groove 31. The lever 33 is fixedly connected to the arc surface of the rotating post 32. The through groove 36 is formed on the rear wall of the locking lever 35, and the stud 37 is threaded into the through groove 36. The receiving groove 31 is a groove with a convex cross-section, and the rotating post 32 is located within the large space of the receiving groove 31. 34 is located in the small space of the receiving groove 31. The receiving groove 31 has circular grooves at the top and bottom that are adapted to the end of the rotating column 32. The rotating column 32 is rotatably connected in the symmetrical circular grooves in the receiving groove 31. The lever 33 is a rectangular rod, and the stud 37 is a worm gear. The wall of the through groove 36 has a threaded hole adapted to the stud 37 in the direction of the slot 38. The stud 37 can pass through the threaded hole in the wall of the through groove 36 and enter the slot 38. The wall of the control rod 30 is provided with a pin structure. The pin structure includes a plug 40, a slot 41, a first indicator block 42 and a second indicator block 43. The plug 40 is fixedly connected to the side wall of the control rod 30. The slot 41 is opened on the side wall of the control rod 30. The first indicator block 42 is symmetrically fixedly connected to the rear wall of the control rod 30, and the second indicator block 43 is symmetrically fixedly connected to the rear wall of the locking rod 35.

[0031] In practical use, when it is necessary to connect and install two sections of the corrugated guard plate body 20, align the control rod 30 on the wall of one corrugated guard plate body 20 with the locking rod 35 on the wall of the other corrugated guard plate body 20. At the same time, the lower control rod 30 and locking rod 35 will be aligned synchronously. Then, insert the insert block 40 on the wall of the control rod 30 into the slot 41 on the wall of the locking rod 35. Simultaneously, the insert block 40 on the wall of the locking rod 35 will be inserted into the slot 41 on the wall of the control rod 30. When the insertion is completed, the inclined surface of the first indicator block 42 will fit against the inclined surface of the second indicator block 43. Then, move the lever 33 into the receiving groove 31. As the lever 33 is moved, it can... The rotating column 32 rotates to the receiving groove 31, and the locking block 34 in the receiving groove 31 will enter the locking groove 38 due to the rotation of the rotating column 32. At this time, the threaded groove on the wall of the locking block 34 will be connected and aligned with the threaded hole in the through groove 36. Then, the stud 37 can be rotated by using a wrench to make the stud 37 pass through the threaded groove and enter the threaded hole on the wall of the locking block 34 and the rotating column 32, thereby fixing the position of the locking block 34 and the rotating column 32. The control rod 30 and the locking rod 35 below are also connected and fixed in the same way. When disassembling, the stud 37 is rotated back into the through groove 36, and then the lever 33 is turned to drive the locking block 34 to separate from the locking groove 38, thereby unlocking the position of the two adjacent wave guard plate bodies 20.

[0032] In summary, by setting up a docking structure, adjacent corrugated guard plate bodies 20 can be docked through a snap-locking method. During installation, only docking of the corrugated guard plate bodies 20, turning the lever 33 and rotating the stud 37 are required to complete the installation. Compared with tightening multiple bolts, this solution is obviously easier and faster to install.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, the insert 40 is a trapezoidal cross-section block, and the slot 41 can be adapted to the size of the insert 40. The positions of the insert 40 and the slot 41 are symmetrical. The side wall of the locking rod 35 also has slots 41 and insert 40. The positions of the slots 41 and insert 40 on the wall of the locking rod 35 are interchanged. The first schematic block 42 is a right-angled trapezoidal block, and the second schematic block 43 is a right-angled triangular block. The inclined surface of the first schematic block 42 faces the inclined surface of the second schematic block 43. The position of the first schematic block 42 is flush with that of the second schematic block 43.

[0034] In actual use, the insert 40 on the wall of the control lever 30 is aligned with the slot 41 on the wall of the locking lever 35 and inserted. At the same time, the insert 40 on the wall of the locking lever 35 will be inserted into the slot 41 on the wall of the control lever 30. When the insertion is completed, the inclined surface of the first indicator block 42 will fit against the inclined surface of the second indicator block 43.

[0035] In summary, by setting a pin structure, the positions of adjacent waveform guard plate bodies 20 can be guided and aligned before fixing them, thereby facilitating the fixing of the waveform guard plate bodies 20 through the docking structure.

[0036] Working principle: When two corrugated guard plate bodies 20 need to be connected and installed, align the control rod 30 on the wall of one corrugated guard plate body 20 with the locking rod 35 on the wall of the other corrugated guard plate body 20. At the same time, the lower control rod 30 and locking rod 35 will be aligned synchronously. Then, insert the plug 40 on the wall of the control rod 30 into the slot 41 on the wall of the locking rod 35. Simultaneously, the plug 40 on the wall of the locking rod 35 will be inserted into the slot 41 on the wall of the control rod 30. When the insertion is completed, the inclined surface of the first indicator block 42 will fit against the inclined surface of the second indicator block 43. Then, the lever 33 is moved into the receiving groove 31. As the lever 33 is moved, it can rotate around the rotating column 32 into the receiving groove 31. At this time, the locking block 34 in the receiving groove 31 will enter the locking groove 38 due to the rotation of the rotating column 32. At this time, the threaded groove on the wall of the locking block 34 will connect and align with the threaded hole in the through groove 36. Then, the stud 37 can be rotated by the wrench to make the stud 37 pass through the threaded groove and enter the threaded hole on the wall of the locking block 34 and the rotating column 32, thereby fixing the position of the locking block 34 and the rotating column 32. The control lever 30 and the locking lever 35 below are also connected and fixed in the same way.
