To this end, the present invention provides a high-rise guardrail for building construction.

[0034] Specifically, a high-rise guardrail for building construction according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0036] Specifically, refer to Figure 1-Figure 5 , this embodiment provides a high-rise guardrail for construction, including: a first U-shaped frame 1, a second U-shaped frame 2 and a fixing block 3;

[0037] The first U-shaped frame 1 and the second U-shaped frame 2 are symmetrically arranged relative to the fixed block 3, and the fixed block 3 includes at least two, and the outer walls at both ends of each fixed block 3 are fixedly connected with a connecting rod 4. The inner walls of the first U-shaped frame 1 and the second U-shaped frame 2 are penetrated with a cavity hole 5 at a position relative to the connecting rod 4.

[0038] The inner hole of each fixed block 3 is rotatably connected to a rotating rod 6, and the outer wall of the rotating rod 6 is fixedly connected to a first windshield block 7 and a second windshield block 9, and the first windshield block 7 and the second windshield block 9 are meshed with each other.

[0039] The high-rise guardrail for construction designed by the present invention can adjust the width of the guardrail according to needs, and can also simultaneously unfold the windshield, so as to avoid the windshield being unable to unfold and affecting the use after the guardrail is unfolded, and the angle of the windshield can be adjusted according to needs.

[0040] It can be understood that there are at least four connecting rods 4 , and one end of each connecting rod 4 extends into the corresponding cavity hole 5 .

[0041] It can be understood from the figure that each connecting rod 4 and the cavity hole 5 are arranged in a circular shape. The circular structure facilitates the movement of the connecting rod 4 in the cavity hole 5.

[0042] It should be noted that a plurality of screw holes 11 are equidistantly provided on the upper and lower outer walls of the first U-shaped frame 1 and the second U-shaped frame 2, and a through hole matching the screw holes 11 is provided on the connecting rod 4; wherein the screw holes 11 are matched with the corresponding through holes on the connecting rod 4, and are both connected and fixed with bolts 12.

[0043] It can be understood that there are at least four screw holes 11 , and each screw hole 11 extends through and into the corresponding connecting rod 4 and is threadedly connected with a bolt 12 .

[0044] The above structure can facilitate the use of bolts 12 to fix the connecting rod 4 to the first U-shaped frame 1 and the second U-shaped frame 2 .

[0045] The upper and lower inner side walls of the first windshield block 7 are penetrated with inner tooth grooves 17, wherein, the outer sides of the upper and lower end surfaces of the second windshield block 9 are provided with limit spring blocks 8 close to the inner side edge of the rotating rod 6, and each pair of the limit spring blocks 8 is engaged with the corresponding inner tooth grooves 17. It can be understood that the second windshield block 9 is fixedly connected to one end of each pair of limit spring blocks 8 and extends to the outside of the corresponding inner tooth grooves 17.

[0046] There are at least two inner tooth grooves 17 , and a pair of limiting spring blocks 8 are disposed inside each inner tooth groove 17 , and each pair of limiting spring blocks 8 abuts against the corresponding inner tooth groove 17 .

[0047] Each pair of the limiting spring blocks 8 has convex teeth, and the convex teeth are engaged with the inner tooth grooves 17 .

[0048] The second windshield block 9 is provided with a plurality of groups of springs 16 on the inner side edge of the rotating rod 6. The springs 16 push the convex teeth to engage in each tooth groove of the inner tooth groove 17; the second windshield block 9 is limited and fixed by the convex teeth.

[0049] It is understandable that the limiting spring block 8 includes but is not limited to the top angle, and the inner tooth groove 17 includes but is not limited to the inner tooth groove 17, and both can be replaced by other components, such as a ratchet and a pawl.

[0050] Specifically, the ratchet wheel has protruding teeth, and the pawl has a plurality of claw grooves. The protruding teeth can be pushed by the spring 16 to move and engage in each claw groove, so that the protruding teeth can be engaged in any claw groove, thereby realizing flexible adjustment and limited fixing of the second wind deflector 9.

[0051] The spring 16 includes at least two groups, and each group of the springs 16 is respectively connected to the second wind shield 9 close to one side of the limiting elastic block 8. The springs 16 facilitate pushing the limiting elastic block 8 to move to both sides.

[0052] One end of the rotating rod 6 extends through a bearing to the outer end of the fixed block 3 to be fixedly connected with a rotating disk 10 . The outer end surface of the rotating disk 10 is circumferentially and equidistantly provided with a plurality of latch holes 13 .

[0053] The latch hole 13 corresponds to the latch hole provided on the end surface of the fixing block 3 , and the latch pin 14 penetrates into the latch hole 13 and the corresponding latch hole in the fixing block 3 to be fixedly connected.

[0054] It is understandable that one end of each latch hole 13 extends through the corresponding fixing block 3 and is slidably connected with a latch 14. The above structure can facilitate the insertion of the latch 14 into the latch hole 13 and the rotation disk 10 can be fixed in position.

[0055] Furthermore, the upper and lower ends of the first U-shaped frame 1 and the second U-shaped frame 2 are fixedly connected with support legs (15). It can be understood that the upper and lower ends of the first U-shaped frame 1 and the second U-shaped frame 2 are symmetrically fixedly connected with at least two support legs 15. The connected support legs 15 make it easier to prop up the guardrail.

[0056] An operation method of a high-rise guardrail for construction provided by an embodiment of the present invention is as follows:

[0057] When in use, the guardrail needs to be unfolded, the bolt 12 is turned out from the screw hole 11, and the first U-shaped frame 1 and the second U-shaped frame 2 are pulled to both sides, and the first U-shaped frame 1 and the second U-shaped frame 2 are moved outside the connecting rod 4 to unfold the guardrail. Align the screw holes 11 opened in the first U-shaped frame 1 and the second U-shaped frame 2 with the screw holes 11 opened in the connecting rod 4, and turn the bolt 12 into the screw hole 11 to fix the first U-shaped frame 1 and the second U-shaped frame 2 to the connecting rod 4. After the first U-shaped frame 1 and the second U-shaped frame 2 are unfolded, pull the second wind shield 9 outward to unfold the second wind shield 9. After the adjustment is completed, the spring 16 pushes the limit block 8 to resist the inner tooth groove 17, and the second wind shield 9 is limited and fixed by the limit block 8. When the angle of the first wind shield block 7 needs to be adjusted, the latch 14 is removed from the latch hole 13, and the turntable 10 is used to drive the rotating rod 6 and the first wind shield block 7 to rotate, and the latch hole 13 opened on the turntable 10 is aligned with the latch hole 13 opened on the fixed block 3, and the latch 14 is inserted into the latch hole 13 to fix the turntable 10 and the fixed block 3.

[0058] The beneficial effects of a high-rise guardrail for construction provided by an embodiment of the present invention are:

[0059] The bolt 12 can be removed from the screw hole 11, and the first U-shaped frame 1 and the second U-shaped frame 2 can be moved to both sides as needed to gradually increase the width of the guardrail. After moving to the desired position, the bolt 12 is inserted into the screw hole 11 to fix the first U-shaped frame 1 and the second U-shaped frame 2. The second windshield block 9 is moved outward. After the second windshield block 9 is moved to the desired position, the spring 16 pushes the limiting spring piece 8 to move into the inner tooth groove 17 to limit and fix the second windshield block 9.

[0060] At the same time, the width of the guardrail can be adjusted according to needs, and the wind shield can be unfolded simultaneously to avoid the situation where the wind shield cannot be unfolded and affects the use after the guardrail is unfolded.

[0061] At the same time, the latch pin 14 can be removed from the latch pin hole 13, and the angle of the first windshield block 7 can be adjusted by the turntable 10. The angle of the windshield block can be adjusted according to needs.
