Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5The utility model provides a technical solution: a metal guardrail with an easily adjustable angle, comprising a fixed rod 1, an adjustment mechanism 2 is arranged at one end of the fixed rod 1, an adaption mechanism 3 is arranged at one side of the adjustment mechanism 2, a second connection block 4 is fixedly connected to one side of the fixed rod 1, a transmission shaft 5 is rotatably connected to the inside of the second connection block 4, a third connection block 6 is rotatably connected to the surface of the transmission shaft 5, and a third railing 7 is fixedly connected to one end of the third connection block 6;

[0021] The adjusting mechanism 2 includes a first connecting rod 201, a first bolt 202, a first nut 203, a first railing 204, a first rotating groove 205, a second connecting rod 206, a second bolt 207, a second nut 208, a second railing 209 and a second rotating groove 210. One end of the surface of the fixed rod 1 is fixedly connected to the first connecting rod 201, the inner wall surface of the first connecting rod 201 is movably sleeved with the first bolt 202, one side of the surface of the first bolt 202 is threadedly connected with the first nut 203, one side of the surface of the first bolt 202 is penetrated and connected with the first railing 204, one side of the surface of the first railing 204 is provided with a first rotating groove 205, the other end of the surface of the fixed rod 1 is fixedly connected to the second connecting rod 206, the inner wall surface of the second connecting rod 206 is movably sleeved with the second bolt 207, and the surface of the second bolt 207 A second nut 208 is threadedly connected to one side, and a second railing 209 is penetrated and connected to one side of the surface of the second bolt 207. A second rotation groove 210 is provided on one side of the surface of the second railing 209. During use, when it is necessary to install a metal guardrail on site, the first railing 204, together with the fixing rod 1, the second railing 209, etc. can be placed on the ground according to the actual needs of the site, and then the first nut 203 is loosened to adjust the angle between the fixing rod 1 and the first railing 204, so that the metal guardrail can be freely installed when the ground height on site is inconsistent. After confirming that the first railing 204 and the second railing 209 are placed stably, the first bolt 202 and the first nut 203 are tightened to fix the angle between the first railing 204, the second railing 209 and the fixing rod 1. At this time, a metal guardrail is installed.

[0022] Furthermore, the fixed rod 1 forms a rotating structure with the first connecting rod 201, the first bolt 202, the first rotating groove 205 and the first railing 204. The first connecting rod 201 can rotate at an angle of 25-35° in the first rotating groove 205. The fixed rod 1 can adjust the angle between the first connecting rod 201, the second connecting rod 206 and the fixed rod 1 through the setting of the first connecting rod 201, the first bolt 202, the first rotating groove 205 and the first railing 204, so that the metal guardrail can be adjusted according to the ground height on site. The first connecting rod 201 can rotate at an angle of 25-35° in the first rotating groove 205. The first rotating groove 205 limits the maximum inclination angle between the fixed rod 1 and the first connecting rod 201 and the second connecting rod 206, thereby enhancing the overall stability of the metal guardrail while maintaining a certain aesthetics, making the metal guardrail look more neat and orderly.

[0023] Further, the adapting mechanism 3 includes a first connecting block 301, a third bolt 302, a third nut 303, a first transmission block 304, a second transmission block 305, a fourth bolt 306, and a fourth nut 307.

A fourth nut 307 is threadedly connected to one side of the surface of the fourth bolt 306. During use, when installing a metal guardrail, after one metal guardrail is installed, the fourth bolt 306 can be passed through the first transmission block 304 and the second transmission block 305 to allow it to rotate, loosen the third nut 303, and then flexibly adjust the metal guardrail according to actual on-site needs. After adjusting to a suitable angle, the third bolt 302, the third nut 303, the fourth bolt 306, and the fourth nut 307 can be tightened respectively to fix the two metal guardrails, and so on to fix multiple metal guardrails, so that the metal protection can adapt to different installation environments and usage requirements.

[0024] Furthermore, the first transmission block 304 forms a rotating structure with the first connecting block 301 through the third bolt 302, and the second transmission block 305 forms a rotating structure with the first transmission block 304 through the third bolt 302. Through the arrangement of the first transmission block 304, the third bolt 302, and the first connecting block 301, the two metal guardrails can adapt to a certain degree of terrain height, thereby increasing the adaptability of the metal guardrails. Through the arrangement of the second transmission block 305, the third bolt 302, and the first transmission block 304, the two metal guardrails can be used in places where the protection range is frequently changed, thereby increasing the applicability of the metal guardrails.

[0025] Furthermore, the first transmission blocks 304 are set to two groups, and the second transmission blocks 305 are set to four groups. By setting the two groups of first transmission blocks 304, the first transmission blocks 304 and the second transmission blocks 305 cooperate with each other to ensure the stable connection between the first railing 204 and the second railing 209, thereby ensuring the stability of the metal guardrail. By setting the four groups of second transmission blocks 305, the stability of the connection between the first railing 204 and the second railing 209 can be guaranteed, thereby ensuring the protective effect of the metal guardrail.

[0026] Furthermore, the first railing 204 is fixedly connected to the second railing 209 through the second transmission block 305, the fourth nut 307, the first transmission block 304, the third bolt 302, and the first connecting block 301. Through the setting of the first railing 204, the second transmission block 305, the fourth nut 307, the first transmission block 304, the third bolt 302, the first connecting block 301, and the second railing 209, the first railing 204 can be freely installed or disassembled from the second railing 209, thereby improving the installation efficiency of the metal guardrail.

[0027] Working principle: During use, when it is necessary to install a metal guardrail on site, the first railing 204, the fixing rod 1, the second railing 209, etc. can be placed on the ground according to the actual needs of the site, and then the first nut 203 is loosened to adjust the angle between the fixing rod 1 and the first railing 204, so that the metal guardrail can be freely installed when the ground height is inconsistent on site. After confirming that the first railing 204 and the second railing 209 are placed stably, the first bolt 202 and the first nut 203 are tightened to fix the first railing 204, the second railing 209 and the fixing rod 1, at this time, a metal guardrail is installed, and then the fourth bolt 306 can be passed through the first transmission block 304 and the second transmission block 305 to make it rotatable, loosen the third nut 303, and then flexibly adjust the metal guardrail according to actual on-site needs. After adjusting to a suitable angle, the third bolt 302, the third nut 303, the fourth bolt 306, and the fourth nut 307 can be tightened respectively to fix the two metal guardrails, and so on to fix multiple metal guardrails, so that the metal protection can adapt to different installation environments and usage requirements.
