DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0021] See also Figure 1-6 The utility model provides a technical solution: a modularly assembled metal guardrail, comprising a fixed rod 1, a splicing mechanism 2 is arranged on one side of the fixed rod 1, a telescopic mechanism 3 is arranged on one end of the splicing mechanism 2, a connecting strip 4 is attached to one end of the splicing mechanism 2, a third bolt 5 is threadedly connected to one end of the connecting strip 4, and a fourth bolt 6 is threadedly connected to one end of the connecting strip 4;

[0022] The splicing mechanism 2 includes a limit strip 201, a first limit block 202, a first fixed block 203, a first sliding hole 204, a first limit groove 205, a first bolt 206, a second fixed block 207, a second sliding hole 208, a second limit groove 209, a second bolt 210, a first connecting rod 211 and a second connecting rod 212.

During use, when it is necessary to assemble the metal guardrail on site, the fixed rod 1 can be placed on site, and the first fixed block 203 and the second fixed block 207 can be sleeved on the fixed rod 1, and then the first bolt 206 and the second bolt 210 are used to fix the first fixed block 203 and the second fixed block 207 to the fixed rod 1 respectively, so as to achieve the effect of quickly assembling the metal guardrail.

[0023] Furthermore, the first fixing block 203 is fixedly connected to the fixing rod 1 by the first bolt 206, and the limiting strip 201 is slidably connected to the first limiting groove 205. By setting the first fixing block 203, the first bolt 206, and the fixing rod 1, the first fixing block 203 can be freely removed or installed on the fixing rod 1, thereby improving the splicing speed of the metal guardrail. By setting the limiting strip 201 and the first limiting groove 205, the first fixing block 203 can be quickly and effectively aligned with the threaded hole during installation, which facilitates the installation of the first bolt 206, thereby speeding up the installation efficiency of the metal guardrail.

[0024] Furthermore, the first fixing blocks 203 are provided in two groups and are symmetrically distributed. By providing two groups of first fixing blocks 203, the first connecting rod 211 can be better fixed to the two groups of fixing rods 1, thereby ensuring the stability of the metal guardrail.

[0025] Furthermore, the telescopic mechanism 3 includes a connecting block 301, a sliding block 302, a third limiting groove 303, a movable groove 304, a spring 305, a limiting column 306, a fixed bar 307, a sliding groove 308, a second limiting block 309 and a through hole 310. One side of the surface of the first connecting rod 211 is fixedly connected to the connecting block 301, and the other end of the connecting block 301 is fixedly connected to the sliding block 302. One side of the surface of the sliding block 302 is provided with a third limiting groove 303, one side of the surface of the sliding block 302 is provided with a movable groove 304, one end of the surface of the movable groove 304 is fixedly connected to the spring 305, and the other end of the spring 305 is fixedly connected to the limiting column 306. The surface of the sliding block 302 is slidably connected to the fixing bar 307, one end of the surface of the fixing bar 307 is provided with a sliding groove 308, one side of the surface of the sliding groove 308 is fixedly connected to the second limiting block 309, and the fixing bar 307 is slidably connected to the surface of the fixing bar 307. A through hole 310 is provided on one side of the surface 307. During use, when it is necessary to assemble the metal guardrail on site, the first connecting rod 211 can be manually pulled out from the sliding groove 308 together with the sliding block 302. When the sliding block 302 moves from the sliding groove 308 to a certain position, the limiting column 306 will move outward a certain distance due to the deformation of the spring 305. When the limiting column 306 slides to the surface of the through hole 310, the interaction between the limiting column 306 and the through hole 310 will limit the displacement of the sliding block 302, thereby achieving the effect of fixing the sliding block 302 and the fixing bar 307, so that the first connecting rod 211 and the second connecting rod 212 are fixed. When disassembly is required, the limiting column 306 only needs to be manually pressed into the movable groove 304 and the sliding block 302 can be slid to complete the recovery. This device has a simple structure and is easy to disassemble and install, and can be flexibly combined according to specific needs.

[0026] Furthermore, the third limit slot 303 is slidably connected to the second limit block 309, and the limit column 306 is slidably connected to the through hole 310. By setting the third limit slot 303 and the second limit block 309, it can be ensured that the third limit slot 303 will not fall off from the sliding slot 308, thereby ensuring the integrity of the telescopic mechanism 3. By setting the limit column 306 and the through hole 310, it can be ensured that the interaction between the limit column 306 and the through hole 310 will limit the displacement of the sliding block 302, thereby making the modular assembled metal guardrail easy to disassemble and replace.

[0027] Furthermore, the fixing bar 307 is fixedly connected to the second connecting rod 212. By setting the fixing bar 307 and the second connecting rod 212, the connection between the first connecting rod 211 and the second connecting rod 212 can be stabilized, thereby improving the stability of the modular assembled metal guardrail.

[0028] Working principle: During use, when it is necessary to assemble the metal guardrail on site, the fixing rod 1 can be placed according to the current site, and then the first fixing block 203 and the second fixing block 207 are sleeved on the fixing rod 1, and then the first bolt 206 and the second bolt 210 are used to fix the first fixing block 203 and the second fixing block 207 to the fixing rod 1 respectively, so as to achieve the effect of quickly assembling the metal guardrail, and the first connecting rod 211 can be manually pulled out from the sliding groove 308 together with the sliding block 302. When the sliding block 302 moves from the sliding groove 308 to a certain position, the limit column 306 will move outward a certain distance due to the deformation effect of the spring 305. When the limit column 306 slides to the surface of the through hole 310, the interaction between the limit column 306 and the through hole 310 will limit the displacement of the sliding block 302, thereby achieving the effect of fixing the sliding block 302 and the fixing bar 307, so that the first connecting rod 211 and the second connecting rod 212 are fixed. When disassembly is required, the limit column 306 only needs to be manually pressed into the movable groove 304 and the sliding block 302 can be recovered. This device has a simple structure and is easy to disassemble and install, and can be flexibly combined according to specific needs.
