[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Please see Figure 1-7 A guardrail for construction of hydraulic structures includes a guardrail body 1 and a support 2. Both sides of the guardrail body 1 are welded with first connecting blocks 4. The outer wall of the support 2 is rotatably connected to two second connecting blocks 5 through a connecting shaft 3. The first connecting blocks 4 and the second connecting blocks 5 are fixedly connected by a snap-fit ​​mechanism.

[0029] The snap-fit ​​mechanism includes multiple sliding grooves 6 opened inside the first connecting block 4, each sliding groove 6 has a slider 7 slidably connected inside, each sliding groove 6 has a groove 8 on its outer wall, and each sliding groove 6 has a first spring 9 inside.

[0030] The snap-fit ​​mechanism also includes multiple protrusions 10 fixedly connected to the outer wall of the second connecting block 5, and each of the multiple protrusions 10 has a snap-fit ​​hole 11 on its outer wall;

[0031] The locking mechanism also includes a movable plate 12. The rear end face of the movable plate 12 is fixedly connected with a plurality of locking rods 13 that match the locking holes 11 and are slidably connected to the first connecting block 4. The rear end face of the movable plate 12 is fixedly connected with two limiting rods 14 that are slidably connected to the first connecting block 4. The rear ends of the two limiting rods 14 are fixedly connected with limiting plates 15. The outer walls of the two limiting rods 14 are each sleeved with a second spring 16 located between the limiting plate 15 and the rear end face of the first connecting block 4.

[0032] In this embodiment: During assembly, the first connecting block 4 and the second connecting block 5 are aligned, and multiple protrusions 10 are inserted into multiple sliding grooves 6 respectively. The protrusions 10 slide into the sliding grooves 6, thereby driving the slider 7 to slide into the sliding grooves 6 and compressing the first spring 9. When the slider 7 slides inward, it further drives the locking rod 13 to slide outward through the groove 8, causing the locking rod 13 to disengage from the groove 8. At the same time, the locking rod 13 drives the movable plate 12 to slide forward, thereby driving the two limiting rods 14 to slide forward and compressing the second spring 16. After the protrusions 10 are fully inserted into the sliding grooves 6, the locking hole 1... Align the first connecting block 4 with the second connecting block 5. At this time, the limiting rod 14 slides to the right under the elastic force of the second spring 16, and then drives the multiple connecting rods 13 to slide backward through the movable plate 12, so that the connecting rods 13 are locked into the locking hole 11, and the first connecting block 4 and the second connecting block 5 are fixed. When disassembling, pull the movable plate 12 forward to release the multiple connecting rods 13 from the locking hole 11. In the assembly of this utility model, the first connecting block 4 and the second connecting block 5 can be directly aligned and brought close to each other to complete the fixation. When disassembling, only the movable plate 12 needs to be pulled to disassemble, making installation and disassembly simpler.

[0033] As a technical optimization of this utility model, the upper end face of the support 2 is threaded with two symmetrically distributed fixing bolts 19, and the upper end face of the second connecting block 5 is provided with multiple slots 20.

[0034] In this embodiment: by unscrewing the fixing bolt 19, the second connecting block 5 can be rotated along the connecting shaft 3. After rotating the second connecting block 5 to a suitable direction, the fixing bolt 19 is screwed back into the support 2, and the threaded end of the fixing bolt 19 is inserted into the slot 20 to fix the second connecting block 5. This utility model can adjust the assembly angle of the two guardrail bodies 1 as needed, and is highly practical.

[0035] As a technical optimization of this utility model, the rear end face of the slider 7 is fixedly connected to the limiting block 18, and the inner wall of the slide groove 6 is provided with a limiting groove 17 that matches the limiting block 18.

[0036] In this embodiment, the limiting groove 17 and the limiting block 18 cooperate to prevent the slider 7 from coming off the sliding groove 6.

[0037] As a technical optimization of this utility model, the groove 8 is a right trapezoid.

[0038] In this embodiment, by setting the groove 8 as a right-angled trapezoid, it is easier to drive the locking rod 13 to slide outward.

[0039] As a technical optimization of this utility model, the rear end of the lever 13 is hemispherical.

[0040] In this embodiment, by setting the rear end of the locking rod 13 to a hemispherical shape, it is easy for the locking rod 13 to be inserted into the locking hole 11.

[0041] As a technical optimization of this utility model, the outer wall of the movable plate 12 is provided with a handle.

[0042] In this embodiment, by providing a handle on the outer wall of the movable plate 12, it is easy to pull the movable plate 12, saving time and effort.

[0043] As a technical optimization of this utility model, the longitudinal section of the slide 6 is rectangular.

[0044] In this embodiment, by setting the longitudinal section of the slide groove 6 to a rectangle, the slider 7 is prevented from rotating inside the slide groove 6.

[0045] The working principle and usage process of this utility model are as follows: During assembly, the first connecting block 4 and the second connecting block 5 are aligned, and multiple protrusions 10 are inserted into multiple sliding grooves 6 respectively. The protrusions 10 slide into the sliding grooves 6, thereby driving the slider 7 to slide into the sliding grooves 6 and compressing the first spring 9. When the slider 7 slides inward, it further drives the locking rod 13 to slide outward through the groove 8, causing the locking rod 13 to disengage from the groove 8. At the same time, the locking rod 13 drives the movable plate 12 to slide forward, thereby driving the two limiting rods 14 to slide forward and compressing the second spring 16. After the protrusions 10 are fully inserted into the sliding grooves 6, the locking hole 11 is aligned with the locking rod 13. At this time, the limiting rod 14 slides to the right under the elastic force of the second spring 16, thereby driving the multiple locking rods 13 to slide backward through the movable plate 12, causing the locking rod 13 to disengage from the groove 8. Rod 13 is inserted into the locking hole 11 to fix the first connecting block 4 and the second connecting block 5. When disassembling, pull the movable plate 12 forward to disengage the multiple locking rods 13 from the locking hole 11. When adjusting the angle of the second connecting block 5, unscrew the fixing bolt 19 and rotate the second connecting block 5 along the connecting shaft 3. After rotating the second connecting block 5 to the appropriate direction, screw the fixing bolt 19 back into the support 2 and insert the threaded end of the fixing bolt 19 into the locking groove 20 to fix the second connecting block 5. When assembling this utility model, the first connecting block 4 and the second connecting block 5 can be aligned and brought close to each other to complete the fixation. When disassembling, only the movable plate 12 needs to be pulled to disassemble. The installation and disassembly are simpler, and the assembly angle of the two guardrail bodies 1 can be adjusted as needed, making it highly practical.
