Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0017] like Figures 1 to 6As shown, a municipal guardrail includes two hollow-structured side connecting posts 1 and a central support post 2. The central support post 2 is the same length as the side connecting posts 1. Each of the two symmetrical sides of the side connecting posts 1 has several connecting slots 3. One side of the central support post 2 has several positioning slots 4. Positioning blocks 5 are engaged with the inner walls of each positioning slot 4. Each positioning block 5 has a connecting through hole 6 on one side. One end of each positioning block 5 is fixedly connected to a hollow-structured protective rod 7. One side of each protective rod 7 is threaded with an adjusting screw. The bolt 8, and several protective rods 7 are slidably connected to extension rods 9 that engage with connecting slots 3. The extension rods 9 are adapted to the size of the protective rods 7 and can be retracted into the protective rods 7. Several adjustment holes 10 are opened on one side of each extension rod 9, and the adjustment holes 10 are evenly distributed on one side of each extension rod 9. Fixed holes 11 are opened on the top side of each extension rod 9. Fixed structures 12 for fixing the extension rods 9 are provided on the side connecting piles 1. Two insertion holes 13 are opened on the top side of the central support pile 2. The inner walls of the two insertion holes 13 are... The guardrail is equipped with first fixed anchor rods 14, and a mounting baffle 15 is fixedly connected to the top of the two first fixed anchor rods 14. Under normal conditions, the municipal guardrail consists of three parts: side connecting piles 1, central support piles 2, and guardrail 7, reducing the overall volume of the municipal guardrail. When the municipal guardrail needs to be used, several positioning blocks 5 are first inserted into several positioning slots 4, thereby connecting the guardrail 7 and the central support pile 2. At this time, the positions of the insertion through holes 13 and the connection through holes 6 correspond. Then, the extension rod 9 is moved out from the inside of the guardrail 7. The extension rod 9 is adjusted according to the actual situation during use. The extension rod 9 extends a suitable length from the inside of the protective rod 7. Then, the adjusting bolt 8 is connected to the adjusting socket 10 in the appropriate position to adjust the extension rod 9 and the protective rod 7 to the appropriate length. Then, the extension rod 9 is inserted into the inside of the connecting slot 3 and fixed by the fixing structure 12. Then, the first fixing anchor rod 14 passes through the inside of the connecting through hole 6 and the insertion through hole 13 and fixes the middle support pile 2 to the ground by the first fixing anchor rod 14. The above steps can be repeated to select an appropriate number of side connecting piles 1, middle support piles 2 and protective rods 7 and perform the connection operation.

[0018] As an optional technical solution of this utility model, the fixing structure 12 includes a plurality of lead screws 1201 connected end to end. The lead screws 1201 are rotatably connected to the side connecting piles 1 through bearings. A crank handle 1202 is fixedly connected to the top of the lead screw 1201 located at the top. Fixing plates 1203 are threadedly connected to the outer surfaces of the plurality of lead screws 1201. Two fixing rods 1204 that are adapted to the size of the fixing insertion hole 12 are fixedly connected to the top side of the plurality of fixing plates 1203. After the extension rod 9 is inserted into the interior of the connecting slot 3, the crank handle 1202 is rotated to make the plurality of lead screws 1201 rotate simultaneously. At this time, the plurality of fixing plates 1203 move upward simultaneously, so that the fixing rods 1204 are inserted into the interior of the fixing insertion hole 11, thereby fixing the extension rod 9.

[0019] As an optional technical solution of this utility model, guide grooves 16 are provided on two symmetrical sides of the side connecting pile 1. The guide grooves 16 are connected to the interior of the side connecting pile 1. The fixing plate 1103 passes through the interior of the guide grooves 16 and is slidably connected to the guide grooves 16. The guide grooves 16 guide the fixing plate 1103 so that the fixing plate 1103 can only move in a straight line along the direction of the guide grooves 16.

[0020] As an optional technical solution of this utility model, the two symmetrical sides of the side connecting pile 1 are fixedly connected to a fixed base plate 17, and a second fixed anchor rod 18 is inserted into one side of the fixed base plate 17. The side connecting pile 1 can be fixed to the ground by the fixed base plate 17 and the second fixed anchor rod 18.

[0021] As an optional technical solution of this utility model, both the positioning slot 4 and the positioning block 5 are T-shaped, and the size of the positioning block 5 is adapted to the positioning slot 4. The positioning block 5 and the positioning slot 4 make the connection between the protective rod 7 and the central support pile 2 more stable.

[0022] As an optional technical solution of this utility model, the position of the adjusting bolt 8 corresponds to that of the adjusting socket 10, and the size of the adjusting bolt 8 is adapted to that of the adjusting socket 10, so that the adjusting bolt 8 can be smoothly connected to the adjusting socket 10.

[0023] As an optional technical solution of this utility model, the positions of the connecting through hole 6 and the insertion through hole 13 correspond, and the diameter of the first fixed anchor rod 14 is adapted to the diameter of the connecting through hole 6. A type of municipal guardrail works as follows: 1) Make several positioning blocks 5 respectively snap into the interior of several positioning slots 4, at which time the positions of the insertion through hole 13 and the connection through hole 6 correspond to each other; 2) Move the extension rod 9 out of the inside of the protective rod 7, and extend the extension rod 9 out of the inside of the protective rod 7 to an appropriate length according to the actual situation during use; 3) Connect the adjusting bolt 8 to the adjusting socket 10 in the appropriate position to fix the extension rod 9. At this time, the fixed socket 11 corresponds to the position of the fixed plug 1204. 4) Rotate the crank handle 1202 to make several lead screws 1201 rotate simultaneously. At this time, several fixing plates 1203 move upward simultaneously, so that the fixing rod 1204 is inserted into the interior of the fixing hole 11 to fix the extension rod 9. 5) The first fixed anchor rod 14 passes through the inside of the connecting through hole 6 and the insertion through hole 13, and the middle support pile 2 is fixed to the ground through the first fixed anchor rod 14. The side connecting pile 1 is fixed to the ground through the second fixed anchor rod 18 and the fixed base plate 17, thereby completing the assembly of the municipal guardrail.

[0024] In summary, this municipal guardrail, through the coordinated arrangement of side connecting piles 1, central support piles 2, connecting slots 3, positioning slots 4, positioning blocks 5, connecting through holes 6, protective rods 7, adjusting bolts 8, extension rods 9, adjusting insertion holes 10, fixing insertion holes 11, fixing structures 12, insertion through holes 13, first fixed anchor rods 14, and installation baffles 15, divides the municipal guardrail into three parts: side connecting piles 1, central support piles 2, and protective rods 7. This reduces the overall volume of the municipal guardrail, facilitates transportation, allows for the selection of an appropriate number of side connecting piles 1, central support piles 2, and protective rods 7 according to actual usage conditions, and enables rapid connection. Furthermore, it allows for adjustment of the protective area of ​​the municipal guardrail, expanding its applicability and improving its practicality and structural flexibility.
