Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a dotting device for positioning pre-embedded parts of railings. Background Technology

[0002] Railings serve to separate and guide, clearly defining the boundaries of the divided areas. Well-designed railings are also highly decorative.

[0003] In existing technologies, railings are installed at construction sites to protect the site and improve safety. However, the embedded parts at the bottom of the railings need to be marked on-site in advance to ensure a high degree of neatness after installation. Currently, lime is sprinkled on the ground to mark the points.

[0004] However, the application of lime relies solely on the skill and experience of the construction workers. As a result, the area marked with dots and circles is not standardized, and the lime powder can be blown away by the wind. This requires re-marking the marked areas, which affects the construction progress. Summary of the Invention

The pre-reserved opening is located on the bottom surface of the base plate 1, and a retaining ring is fixed to the inner ring surface of the pre-reserved opening. The connecting plate 4 is movably inserted into the pre-reserved opening. The arc-shaped sidewall of the connecting plate 4 has external threads, and the arc-shaped sidewall of the pre-reserved opening has internal threads. The internal and external threads are connected in a mating manner. The soil-inserting handle 6 is fixed to the bottom surface of the connecting plate 4, and the bottom end of the soil-inserting handle 6 is integrally formed with a... The cone head and the washer 7 are fitted and fixed on the rod body of the soil insertion handle 6. The inner ring diameter of the retaining ring is larger than the outer ring diameter of the washer 7. The finger groove 5 is opened on the top surface of the connecting plate 4. There are multiple finger grooves 5, which are arranged in a circular pattern. The rib plate 8 is fixed on the top surface of the washer 7. One side of the rib plate 8 is fixed on the surface of the soil insertion handle 6. There are multiple rib plates 8, which are arranged around the soil insertion handle 6. The digging groove 9 is a "U" shaped groove. The digging groove 9 is opened on the surface of the washer 7. There are multiple digging grooves 9, which are distributed alternately with the rib plate 8.

[0029] After using the dotting device, to prevent the soil-inserting handle 6 from puncturing surrounding objects during storage, insert your finger into the retrieval groove 9 and twist the connecting plate 4 to detach it from the reserved opening. Then, rotate the connecting plate 4 so that the cone head of the soil-inserting handle 6 can be inserted into the reserved opening. Finally, screw the connecting plate 4 back into the reserved opening, thus concealing the soil-inserting handle 6 between the base plate 1 and the lifting plate 12. Example 3:

[0030] See attached document Figure 4, on the basis of the second embodiment, in order to achieve the lifting control of the marking pressing ring 10, the bottom plate 1 is in an inverted "convex" - shaped plate structure, the marking pressing ring 10 is in an annular structure with a right - angled trapezoidal cross - section, the marking pressing ring 10 is sleeved in the bottom annular groove of the bottom plate 1, multiple side grooves are opened on the top surface of the bottom plate 1, the lifting traction mechanism includes a traction handle 11, a lifting plate 12, rubber columns 13 and springs 14.

One end of the traction handle 11 passes through the side groove and is fixed on the top surface of the marking pressing ring 10, and the other end of the traction handle 11 is fixed on the side wall of the lifting plate 12. Multiple rubber columns 13 and springs 14 are fixed on the bottom surface of the lifting plate 12, and the other ends of the rubber columns 13 and springs 14 are fixed on the top surface of the bottom plate 1, and the springs 14 are sleeved on the outside of the rubber columns 13. The lifting traction mechanism further includes a mounting frame 17 and an electric telescopic rod 18. The mounting frame 17 is in a "C" - shaped plate structure, the mounting frame 17 is fixed on the bottom surface of the mounting plate 16, the electric telescopic rod 18 is fixed in the mounting frame 17, and the piston rod of the electric telescopic rod 18 passes through the bottom plate of the mounting frame 17 and is fixed on the top surface of the lifting plate 12. There are multiple connecting support plates 15, and the multiple connecting support plates 15 are arranged and distributed along the edge of the circular surface of the bottom plate 1..

[0031] Insert the cone head of the soil - entering handle 6 into the soil layer, and the spacer ring 7 is lapped on the ground. At this time, start the electric telescopic rod 18 to push the lifting plate 12 downward. The lifting plate 12 drives the traction handle 11 to squeeze the marking pressing ring 10 downward, and the marking pressing ring 10 presses out a concave annular groove on the ground, constituting the limitation of the installation range of the guardrail embedded part. And in this process, the rubber columns 13 and the springs 14 are squeezed and deformed. After the electric telescopic rod 18 lifts the lifting plate 12, the marking pressing ring 10 retracts into the bottom groove of the bottom plate 1 for storage, and the rubber columns 13 and the springs 14 rebound and reset Embodiment Four:

[0032] Refer to the appendix Figure 5 and Figure 6Based on Embodiment 3, in order to achieve the limiting and fixing of the telescopic handrail after adjustment, the telescopic handrail includes a support tube 19, an extension tube 20, a connecting handle 21, and a handle 22. The support tube 19 is fixed to the top surface of the mounting plate 16, the extension tube 20 is sleeved on the tube body of the support tube 19, the connecting handle 21 is fixed to the top end of the extension tube 20, and two handles 22 are symmetrically fixed to the surface of the connecting handle 21. The positioning clamp includes an ear plate 23, a notch 24, a clamping block 25, a reserved groove 26, a stop bar 27, a rubber clamping block 28, a push ring 29, and a stop plate 30. The ear plate 23 has an arc-shaped plate structure, and there are two ear plates 23. The two ear plates 23 are symmetrically distributed about the opening of the extension tube 20, and the ear plates 23 are fixed to the bottom end of the extension tube 20. A groove 24 is formed at the end of the ear plate 23 away from the extension tube 20. A clamping block 25 is movably inserted into the groove 24. A rubber sheet is fixed at one end of the clamping block 25, and an inclined surface is provided at the other end of the clamping block 25, with the inclined surface facing the extension tube 20. A reserved groove 26 is formed on the surface of the clamping block 25. A stop bar 27 extends into the reserved groove 26. The two ends of the stop bar 27 are respectively fixed on two parallel side walls of the reserved groove 26. A rubber clamping block 28 is fixed between the reserved groove 26 and the stop bar 27. A push ring 29 is sleeved on the tube body of the extension tube 20. The inner ring surface of the push ring 29 is provided with an internal thread, and the outer wall of the extension tube 20 is provided with an external thread. The push ring 29 and the extension tube 20 are screwed together. Multiple paddles are fixed on the outer ring surface of the push ring 29. A stop bar 30 is fixed on the outer ring surface of the ear plate 23.

[0033] When the push ring 29 slides along the extension tube 20, the push ring 29 presses the clamping block 25 along the inclined surface to clamp the support tube 19. When the clamping block 25 moves, it presses the rubber clamping block 28 to deform. This achieves quick fixation of the extension tube 20 and the support tube 19 after extension and retraction. When it is necessary to adjust the extension tube 20 and the support tube 19, simply unscrew the push ring 29 to stop blocking the clamping block 25. The rubber clamping block 28 springs back and pushes the clamping block 25 back to its original position. In this way, the clamping block 25 no longer clamps the support tube 19.
