[0019] The present utility model will be further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 where Figure 1 is a schematic structural view of the municipal bridge guardrail structure provided by the present utility model; Figure 2 is a three-dimensional view of the structure of the present utility model; Figure 3 is a side view of the connection between the mounting block and the guardrail of the present utility model; Figure 4 is a schematic view of the connection between the base and the vertical rod of the present utility model. A municipal bridge guardrail structure includes a base 2 provided on a bridge 1. A vertical rod 3 is provided on the top of the base 2. A guardrail 4 is provided on one side of the vertical rod 3. A reflective sticker 5 is fixed on the outer side of the guardrail 4, and the reflective sticker 5 plays a guiding role at night. The bottom end of the vertical rod 3 is inserted into a slot 201 opened on the top of the base 2. A first jack 301 is opened inside the vertical rod 3. A fixed rod 302 is inserted into the first jack 301. Both ends of the fixed rod 302 extending out of the first jack 301 are inserted into second jacks 202 opened on the base 2. A lifting ring 303 is sleeved outside the vertical rod 3. A chamber 304 is opened inside the vertical rod 3. A slide bar 305 is fixed inside the chamber 304. A slide block 306 is slidably connected to the outer side of the slide bar 305. A connecting rod 307 is fixed on one side of the slide block 306. The connecting rod 307 is slidably connected in a slide hole 308 opened on the vertical rod 3. One end of the connecting rod 307 extending out of the slide hole 308 is fixed on the lifting ring 303. A first spring 309 is sleeved outside the slide bar 305 inside the chamber 304. Both ends of the first spring 309 are respectively fixed to the top of the slide block 306 and the inner top wall of the chamber 304.

[0021] Through the above technical solution, when it is necessary to disassemble and replace the guardrail, pull the lifting ring 303 upward, then remove the fixing rod 302, release the restriction of the fixing rod 302 on the vertical rod 3, pull the vertical rod 3 upward, separate the vertical rod 3 from the base 2, so that the disassembly of the guardrail is more convenient, saving working time. And when it is necessary to install a new guardrail, insert the bottom end of the vertical rod 3 into the slot 201, then insert the fixing rod 302 into the first jack 301 and the second jack 202, fix the vertical rod 3 in the slot 201 through the fixing rod 302, and cover the fixing rod 302 through the lifting ring 303, thus completing the assembly of the vertical rod 3 and the base 2. When the lifting ring 303 moves upward, it drives the connecting rod 307 and the slider 306 to move upward, and the slider 306 squeezes the first spring 309. When the lifting ring 303 moves downward, the extrusion force on the first spring 309 disappears, making the covering of the lifting ring 303 on the fixing rod 302 more stable.

[0022] Referring to Figure 1 , a friction pad 203 is fixed at the bottom of the base 2, an expansion bolt 101 is arranged in the bridge 1, the top end of the expansion bolt 101 passes through the first through hole 204 opened in the base 2 and then extends into the slot 201, and a nut 102 is locked on the outer side of the expansion bolt 101. The expansion bolt 101 is fixed in the bridge 1 in advance, the base 2 is inserted on the outer side of the expansion bolt 101, and then the nut 102 is locked on the expansion bolt 101, and the base 2 is fixed on the bridge 1 through the expansion bolt 101. The friction pad 203 is used to increase the friction force between the base 2 and the bridge 1.

[0023] Referring to Figure 1 , Figure 2 and Figure 3 , an installation block 310 is fixed on the outer side of the vertical rod 3, the guardrail 4 is inserted into the groove 311 opened in the installation block 310, a second through hole 401 is opened inside the guardrail 4, a second spring 402 is arranged inside the second through hole 401, pressing plates 403 are fixed at both ends of the second spring 402, a limiting rod 404 is fixed on the side of the pressing plate 403 away from the second spring 402, one end of the limiting rod 404 is inserted into the limiting hole 312 opened in the installation block 310, and a baffle 405 is sleeved on the outer side of the limiting rod 404 and inside the second through hole 401, and the outer side of the baffle 405 is fixedly connected to the inner wall of the second through hole 401. Insert the guardrail 4 into the groove 311 opened in the installation block 310, and the limiting rod 404 in the second through hole 401 is inserted into the limiting hole 312 opened in the installation block 310 under the elastic action of the second spring 402. The guardrail 4 and the installation block 310 can be fixed together through the limiting rod 404, and then the guardrail 4 is installed between the two vertical rods 3. The baffle 405 limits the movement of the pressing plate 403 to prevent the pressing plate 403 from moving outside the second through hole 401 under the elastic action of the second spring 402.

[0024] Referring to Figure 1 , two L-shaped reinforcing bars 406 are provided at the top of the guardrail 4. The bottom ends of the L-shaped reinforcing bars 406 are inserted into the second slots 313 opened at the top of the vertical rods 3. A first threaded groove 407 is opened inside the L-shaped reinforcing bar 406. A threaded rod 408 is screwed inside the first threaded groove 407. One end of the threaded rod 408 extending out of the first threaded groove 407 is screwed into the second threaded groove 409 opened in another L-shaped reinforcing bar 406. When two adjacent vertical rods 3 are in use, the bottom ends of the two L-shaped reinforcing bars 406 are respectively inserted into the second slots 313 opened in the two vertical rods 3, and the threaded rod 408 inside the first threaded groove 407 is rotated to screw one end of the threaded rod 408 into the second threaded groove 409. The two L-shaped reinforcing bars 406 are fixed together through the threaded rod 408, and then the two vertical rods 3 are connected together through the two L-shaped reinforcing bars 406, making the two vertical rods 3 more firm and reliable when in use.

[0025] Referring to Figure 1 , an arc-shaped limiting block 410 is fixed on the outer side of the L-shaped reinforcing bar 406. An arc-shaped limiting groove 314 is opened on the side wall of the second slot 313 of the vertical rod 3. The arc-shaped limiting block 410 is inserted into the arc-shaped limiting groove 314. When the bottom end of the L-shaped reinforcing bar 406 is inserted into the second slot 313, the arc-shaped limiting block 410 on its outer side is inserted into the arc-shaped limiting groove 314, and the L-shaped reinforcing bar 406 is limited by the arc-shaped limiting block 410 to prevent the L-shaped reinforcing bar 406 from moving up randomly.

[0026] The implementation principle of a municipal bridge guardrail structure in an embodiment of the present utility model is as follows: when it is necessary to disassemble and replace the guardrail, the lifting ring 303 is pulled upward, and then the fixing rod 302 is removed to release the restriction of the fixing rod 302 on the vertical rod 3. The vertical rod 3 is pulled upward to separate the vertical rod 3 from the base 2, making the disassembly of the guardrail more convenient and saving working time. When a new guardrail needs to be installed, the bottom end of the vertical rod 3 is inserted into the slot 201, and then the fixing rod 302 is inserted into the first jack 301 and the second jack 202. The vertical rod 3 is fixed in the slot 201 through the fixing rod 302, and the fixing rod 302 is covered by the lifting ring 303 to complete the assembly of the vertical rod 3 and the base 2.
