For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] The utility model is further described below in conjunction with the accompanying drawings:

[0031] like Figure 1-Figure 9 As shown, a protective device for construction includes a guardrail 4 for protection, a fixing mechanism 2 and a supporting mechanism 1 for fixing the guardrail 4, and a locking mechanism 3 for adjusting the locking effect of the fixing mechanism 2. Both sides of the guardrail 4 are connected to the supporting mechanism 1 through locking rings, the locking mechanism 3 is installed inside the supporting mechanism 1, and the bottom of the locking mechanism 3 is connected to the fixing mechanism 2;

[0032] The support mechanism 1 includes an upper fixed sleeve 11, a matching sleeve 14 is inserted inside the upper fixed sleeve 11, a lower fixed sleeve 12 is fixed to the bottom of the matching sleeve 14, a base 13 is welded to the bottom of the lower fixed sleeve 12, and the inner side of the upper fixed sleeve 11 is connected to the fixing mechanism 2 through a matching component;

[0033] The fixing mechanism 2 includes a column 22, which is vertically slidably connected to the lower fixed sleeve 12 and the matching sleeve 14. A locking hook 21 is formed at the bottom of the column 22. The column 22 is located on the outer side of the matching sleeve 14 and is wrapped with a center return spring 23. The center return spring 23 is located on the top surface of the matching sleeve 14, and the top surface of the center return spring 23 is fixedly connected to the inner wall of the upper fixed sleeve 11. The top of the column 22 is connected to a top support spring 24 through a snap buckle, and the top support spring 24 is located between the top surface of the column 22 and the top surface inside the upper fixed sleeve 11.

[0034] In this embodiment, if Figure 6 and Fig. 9 As shown, the mating components inside the upper fixed sleeve 11 include a mating gear 15 and a locking tooth block 16. The two mating gears 15 are symmetrically arranged on both sides of the mating sleeve 14, and the mating gear 15 is connected to the rolling gear 17 on the mating sleeve 14 through a ratchet. The locking tooth block 16 is embedded and connected to the position of the mating gear 15 on the column 22. A tooth block is formed on the inner side surface of the upper fixed sleeve 11 corresponding to the position of the rolling gear 17, and a tooth block is also formed on the outer side surface of the locking tooth block 16 corresponding to the position of the mating gear 15.

[0035] In this embodiment, if Figure 6 As shown, the locking mechanism 3 includes a torsion sleeve 32, and the torsion sleeve 32 of the locking mechanism 3 is slidably connected to the column 22 of the fixing mechanism 2. The torsion sleeve 32 passes through the top of the column 22 and is connected to the tension rod 33 inside the column 22. Blocks are symmetrically formed on both sides of the tension rod 33. A groove for matching the block is formed on the inner wall of the torsion sleeve 32. The lower end of the tension rod 33 is connected to a support block 34 by bolts. The support block 34 is arranged between two locking tooth blocks 16. The support block 34 is a conical block. A matching thread 35 is formed at the center of the tension rod 33. A thread is also formed on the inner wall of the column 22 at a position corresponding to the matching thread 35. The matching thread 35 cooperates with the thread on the inner wall of the column 22. A locking cap 31 for locking is connected to the top of the torsion sleeve 32 by bolts.

[0036] In this embodiment, the locking cap 31 of the locking mechanism 3 is slidably connected to the upper fixed sleeve 11 of the support mechanism 1, and the outer circumferential surface of the locking cap 31 is symmetrically integrally formed with protrusions, and the top of the upper fixed sleeve 11 is formed with a through groove that matches the locking cap 31, and a locking groove that matches the protrusion on the locking cap 31 is formed in the through groove.

[0037] In this embodiment, both ends of the guardrail 4 are connected to locking rings by bolt welding, and the locking rings are connected to the upper fixing sleeve 11 and the lower fixing sleeve 12 by bolts.

[0038] In this embodiment, if Figure 6 , Figure 7 and Figure 8As shown, the two protrusions on the locking cap 31 slide down and then rotate. At this time, the protrusions are locked in the L-shaped grooves in the upper fixed sleeve 11. At this time, the locking cap 31 drives the torsion sleeve 32 to rotate to form a locked state, as shown in FIG. Figure 2 and Figure 6 As shown, when the torsion sleeve 32 and the elastic rod 33 are driven by the locking cap 31 to rotate and reach the locking position, the distance between the top surface inside the torsion sleeve 32 and the top surface of the elastic rod 33 is greater than the distance between the bottom surface of the upper fixed sleeve 11 and the top surface of the lower fixed sleeve 12.

[0039] In this embodiment, the end surface of the locking tooth block 16 that cooperates with the support block 34 is an inclined surface, and the inner side surface of the locking tooth block 16 and the outer circumferential surface of the support block 34 are both formed with friction patterns.

[0040] Working principle: when it is necessary to fix at the construction position, the device is pre-clamped on the edge of the mold by using the locking hook 21 and the base 13, and then the locking cap 31 is rotated to make the torsion sleeve 32 drive the elastic rod 33 to rotate through the block on the elastic rod 33, and the elastic rod 33 cooperates with the column 22 through the matching thread 35. When the elastic rod 33 rotates, the column moves downward under the action of the thread matching, so that the column 22 drives the bottom support block 34 to squeeze and support the two locking tooth blocks 16, so that the two locking tooth blocks 16 are tightly pressed against the matching sleeve 14. At this time, the inner side surface of the upper fixed sleeve 11 squeezes the matching sleeve 14 and the locking tooth block 16, so that the locking tooth block 16 and the column 22 are pre-locked;

[0041] At this time, the upper fixed sleeve 11 is pressed downward, and the upper fixed sleeve 11 cooperates with the locking tooth block 16 through the matching gear 15. The locking tooth block 16 is subjected to the meshing force of the matching gear 15, and drives the column 22 to move upward. The bottom of the column 22 is locked because the locking hook 21 and the base 13 cooperate. At this time, the base 13 and the locking hook 21 lock the edge of the mold, and the device is installed and fixed;

[0042] During use, if vibration occurs and causes the guardrail 4 to shake, because the vibration causes the guardrail 4 to shake continuously up and down, when the guardrail 4 shakes upward, because the matching gear 15 is connected to the rolling gear 17 on the matching sleeve 14 through the ratchet, the rolling gear 17 is driven by the guardrail 4 and the fixed sleeve 11 to rotate, and the matching gear 15 does not respond. When the guardrail 4 shakes downward, the rolling gear 17 engages the matching gear 15 through the ratchet, and the matching gear 15 engages the locking tooth block 16, and the device will not loosen, thereby avoiding the loosening caused by the guardrail 4 being fixed by bolts in conventional equipment. At the same time, even if a human body impacts the guardrail 4, the center return spring 23 and the top support spring 24 can be used to generate a buffer, and this type of impact is used to tighten the lock hook 21 again through the matching gear 15 and the locking tooth block 16 to improve safety.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
