[0011] Compared with the prior art, the advantages and positive effects of the utility model are:
[0012] 1. The utility model discloses a utility model, when the municipal anti-collision device is used to maintain both sides of the road, multiple devices can be placed for installation and use according to the needs of the length of the road. The device is installed on both sides of the road by using fixing screws to penetrate and embed multiple bolt holes one in advance, and then the inner pillar is inserted downward into the interior of the outer sleeve, and the limiting groove is limited by the limiting strip. After the inner pillar is fixed, the connecting column is picked up, and the trapezoidal limiting blocks fixedly connected on both sides thereof are embedded in its two trapezoidal grooves. After the connecting column is fixed, the connecting plate is picked up, and the two T-shaped limiting rods fixedly connected on its surface are embedded in the interior of the two T-slots one and the two T-slots from one side, and the connecting column is fixed.

[0013] When the two limit rods move, they both drive the two support columns mounted at both ends thereof to move obliquely rearward. When the four support columns move, they both drive the two rotating shafts embedded on the surfaces thereof to move. When the four rotating shafts move, they both drive the connecting blocks on both sides thereof to rotate and move at the same time. The four support columns are evenly located on both sides. Therefore, at this time, the multiple connecting blocks on both sides all move downward in opposite directions, thereby driving the multiple springs 1 connected to the surfaces of the two relative connecting blocks on both sides to stretch, thereby absorbing the impact force transmitted by the baffle. When the support columns on both sides move, the four springs 2 and the damper connected to the support columns are pressed downward at the same time. The four springs 2 are all pressed downward under pressure and absorb the impact force transmitted by the baffle together with the springs 1. In this way, the steel plate is avoided from being directly connected to the base. When the steel plate is hit by a vehicle, the impact force caused by the collision can be effectively buffered by multiple groups of springs, thereby reducing the damage to the steel plate.

[0028] In one embodiment, the quick-release assembly 2 includes two inner pillars 201, and the bottoms of the two side surfaces of the two inner pillars 201 are provided with limiting grooves 202, and the bottoms of the surfaces of the two inner pillars 201 are provided with two bolt holes three 203, and the opposite side surfaces of the two inner pillars 201 are provided with trapezoidal grooves 204, the surface of one of the inner pillars 201 is provided with two T-slots one 205, and the surface of the other inner pillar 201 is provided with two T-slots 206, and the insides of the two trapezoidal grooves 204 are movably embedded with trapezoidal limiting blocks 207, and the opposite side surfaces of the two trapezoidal limiting blocks 207 are fixedly installed with connecting columns 208, and the two sides of the surface of the connecting column 208 are provided with two bolt holes four 209, the two T-slots one 205 and the two T-slots 206 are evenly divided into two groups, and the insides of the two groups of T-slots one 205 and T-slots 206 are movably embedded with T-limiting rods 210, and one end of the two T-limiting rods 210 is fixedly installed at both ends of the surface of one side of the connecting plate 3.
[0029] Specifically: after fixing the inner support 201, pick up the connecting column 208, and the trapezoidal limit blocks 207 fixedly connected on both sides thereof are aligned with and embedded into the two trapezoidal grooves 204 thereof. After the connecting column 208 is fixed, the two T-shaped limit rods 210 are embedded into the two T-slots 1 205 and the two T-slots 206 from one side, and the connecting column 208 is fixed. Subsequently, the fixing bolts are driven into the bolt holes 4 209 and the bolt holes 5 301, so that they can be quickly assembled and fixed. Moreover, since the two T-slots 1 205 are both closed at one end, when the two T-shaped limit rods 210 are embedded into the two T-slots 1 205 along the two T-slots 206, ensure that they will not be over-embedded.
[0030] In one embodiment, the energy absorption component 4 includes four fixed blocks 401, one end of the four fixed blocks 401 is fixedly installed at the center of one side surface of the connecting plate 3, the four fixed blocks 401 are evenly divided into two groups, the two ends of the opposite sides of the two groups of fixed blocks 401 are connected to the support column 402 through a movable shaft, the center of the four support columns 402 is embedded with a rotating shaft 403 through a bearing, the two ends of the four rotating shafts 403 are connected to the connecting blocks 404, the eight connecting blocks 404 are evenly divided into four groups, and the opposite sides of the four groups of connecting blocks 404 are connected to the spring 1 405.
[0031] Specifically: when hit, the four support columns 402 are exposed to the impact force and move obliquely rearward. When the four support columns 402 move, they all drive the two rotating shafts 403 embedded in the surface to move. When the four rotating shafts 403 move, they all drive the connecting blocks 404 on both sides to rotate and move at the same time. The four support columns 402 are evenly located on both sides. Therefore, at this time, the multiple connecting blocks 404 on both sides all move downward in opposite directions, thereby driving the multiple springs 405 connected to the surfaces of the connecting blocks 404 on both sides to stretch, thereby absorbing the transmitted impact force.
[0032] In one embodiment, spring 2 406 is fixedly connected to the surface of one end of the four support columns 402, dampers 407 are fixedly installed on the surface of one end of the four support columns 402, rotating blocks 408 are fixedly installed on one end of the four springs 2 406 and the four dampers 407, both ends of the four rotating blocks 408 are movably connected to clamps 409 through movable shafts, the bottoms of the multiple clamps 409 are fixedly installed on one side surface of the connecting plate 3, two limiting rods 410 are fixedly embedded on the top of one end of the four support columns 402, limiting strip grooves 411 are movably sleeved on both ends of the two limiting rods 410, one side surface of the two limiting strip grooves 411 is fixedly connected to one side surface of the baffle 5, and the four dampers 407 are located on the inner side of the four springs 2 406.
[0033] Specifically: when the support columns 402 on both sides move, four springs 406 and dampers 407 connected to the support columns 402 are pressed down at the same time. The four springs 406 are pressed down by the pressure and absorb the transmitted impact force together with the spring 1 405, and the two limiting rods 410 are limited by the two limiting grooves 411.
[0034] In one embodiment, the two inner pillars 201 are movably embedded in the two outer sleeves 102 , and the four limiting grooves 202 are movably sleeved on the surfaces of the four limiting strips 103 .
[0035] Specifically, the two inner pillars 201 are movably embedded in the two outer sleeves 102 , and the four limiting grooves 202 are movably sleeved on the surfaces of the four limiting bars 103 , so that fixation and quick disassembly and assembly can be achieved.
[0036] In one embodiment, the four bolt holes 2 104 and the four bolt holes 3 203 are connected with fixing bolts inside, and the four bolt holes 4 209 and the four bolt holes 5 301 are connected with fixing bolts inside.
[0037] Specifically: the four bolt holes 2 104 are interconnected with the four bolt holes 3 203, and the four bolt holes 4 209 are interconnected with the four bolt holes 5 301. By connecting the fixing bolts between the four bolt holes 2 104 and the four bolt holes 3 203, and connecting the fixing bolts between the four bolt holes 4 209 and the four bolt holes 5 301, the tightness of the device after installation can be ensured.
[0038] Working principle: When the municipal anti-collision device is used to maintain both sides of the road, multiple devices can be placed for installation and use according to the length of the road. The device is installed on both sides of the road using fixing screws to penetrate multiple bolt holes 101 embedded in advance, and then the inner support 201 is inserted downward into the interior of the outer sleeve 102, and the limiting groove 202 is limited by the limiting strip 103. After the inner support 201 is fixed, the connecting column 208 is picked up, and the trapezoidal limiting blocks 207 fixedly connected on both sides are aligned with the two trapezoidal grooves 204 and embedded into them. After the connecting column 208 is fixed, The connecting plate 3 is lifted, and the two T-shaped limit rods 210 fixedly connected on its surface are embedded into the two T-shaped slots 1 205 and the two T-shaped through slots 206 from one side, and the connecting column 208 is fixed, and then the fixing bolts are driven into the bolt hole 2 104 and the bolt hole 3 203, and the bolt hole 4 209 and the bolt hole 5 301, so that the device is fixed as a whole. When disassembly, maintenance and replacement are required, all fixing bolts are removed, and then the various components can be disassembled in the reverse order of the above. This method solves the problem that most municipal anti-collision devices are integrated and inconvenient to assemble, disassemble, maintain and replace. When a vehicle collision accident occurs, the baffle plate 5 first bears the main impact force brought by the collision. The baffle plate 5 moves backward under the impact force, driving the two limit rods 410 to move obliquely rearward along the two limit strip grooves 411. When the two limit rods 410 move, they drive the two support columns 402 mounted at both ends thereof to move obliquely rearward. When the four support columns 402 move, they drive the two rotating shafts 403 embedded on their surfaces to move. When the four rotating shafts 403 move, they drive the connecting blocks 404 on both sides to rotate and move at the same time. The four support columns 402 are evenly located on both sides. Therefore, at this time, multiple connecting blocks 404 on both sides 04 all move downward in opposite directions, thereby driving the spring one 405 connected to the surfaces of the multiple relative connecting blocks 404 on both sides to stretch, thereby absorbing the impact force transmitted by the baffle 5, and when the support columns 402 on both sides move, four spring twos 406 and dampers 407 connected to the support columns 402 are pressed down at the same time, and the four spring twos 406 are pressed down under pressure to absorb the impact force transmitted by the baffle 5 together with the spring one 405. In this way, the steel plate is avoided from being directly connected to the base, and when it is hit by a vehicle, the impact force caused by the collision can be effectively buffered by multiple groups of springs, thereby reducing the damage to the steel plate.
