Description

Technical Field

[0001] This utility model belongs to the field of guardrail technology, specifically referring to a municipal guardrail. Background Technology

[0002] Road guardrails are an essential separation facility on roads. They divide roads into lanes in multiple directions, allowing vehicles to drive in an orderly manner and alleviating traffic congestion. In addition, road guardrails can also separate traffic flow from pedestrians, thus ensuring pedestrian safety to a certain extent.

[0003] However, existing municipal guardrails are all made of metal and fixed with bolts, which is troublesome to install, heavy, and causes great damage to vehicles in the event of a collision. Moreover, the replacement cost of metal guardrails is high and the safety factor is low. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model proposes a municipal guardrail that effectively solves the problems of municipal guardrails being made of metal fences fixed with bolts, which are troublesome to install, heavy, cause great vehicle damage in the event of a collision, and have high replacement costs and low safety factor.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a municipal guardrail, including a counterweight and a protective structure. The protective structure is disposed on the counterweight and includes a guardrail unit and a fixing unit. The guardrail unit is disposed on the counterweight and the fixing unit is disposed on the counterweight. The fixing unit controls the installation and disassembly of the guardrail unit.

[0006] The guardrail unit includes a post, a dovetail base, a splicing base, a barrier, and a limiting hole. The post is fixedly installed above the counterweight base. The dovetail base is fixedly installed on both sides of the post. The splicing base is slidably spliced ​​on the dovetail base. The barrier is fixedly installed between the two sets of splicing bases. The limiting hole passes through the middle of the splicing base.

[0007] Preferably, the fixing unit includes a movable groove, a socket, a limiting pin, a spring, a push plate, a limiting groove, and a top cover. The movable groove is located in the upper part of the counterweight base and is arranged symmetrically on the left and right sides. The socket is located on the left and right sides of the middle part of the counterweight base and is arranged symmetrically in two sets. The limiting pin is slidably disposed in the socket. The spring is disposed in the socket and is fixed at one end to the limiting pin and at the other end to the inside of the counterweight base. The push plate passes through the movable groove and is fixedly disposed on the limiting pin, and the push plate slides left and right in the movable groove. The limiting groove is located at the top of the counterweight base, and the top cover is inserted into the upper limiting groove of the counterweight base.

[0008] To better avoid significant collision damage, the guardrail is made of elastic carbon fiber material.

[0009] To achieve faster installation and fixation, a dovetail groove with the same shape as the dovetail seat is provided on one side of the splicing base.

[0010] Furthermore, the inner diameter of the socket is set to be narrow at the front end and wide at the rear end, and the diameter of the front end of the socket is the same as the diameter of the limiting hole.

[0011] To achieve the protective effect, two sets of splicing seats are set at both ends of the isolation fence and are respectively slidably spliced ​​to the dovetail seats on the left and right counterweight seats.

[0012] The beneficial effects of this utility model using the above structure are as follows: The municipal guardrail proposed in this solution is made of elastic carbon fiber material, which is lightweight, has good buffering performance in the event of a collision, and will not cause damage to vehicles. The guardrail is also low in replacement cost and can be quickly replaced by plugging and unplugging splicing brackets, making it easy to install. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes a municipal guardrail, which includes a counterweight 1 and a protective structure 2. The protective structure 2 is disposed on the counterweight 1 and includes a guardrail unit 3 and a fixing unit 4. The guardrail unit 3 is disposed on the counterweight 1 and the fixing unit 4 is disposed on the counterweight 1. The fixing unit 4 controls the installation and disassembly of the guardrail unit 3.

[0021] The guardrail unit 3 includes a post 5, a dovetail base 6, a splicing base 7, a barrier 8, and a limiting hole 9. The post 5 is fixedly installed above the counterweight base 1. The dovetail base 6 is fixedly installed on both sides of the post 5. The splicing base 7 is slidably spliced ​​on the dovetail base 6. A dovetail groove with the same shape as the dovetail base 6 is provided on one side of the splicing base 7. The barrier 8 is fixedly installed between the two sets of splicing bases 7. The barrier 8 is made of elastic carbon fiber material. Two sets of splicing bases 7 are set at both ends of the barrier 8 and are slidably spliced ​​to the dovetail bases 6 on the left and right sides of the counterweight base 1. The limiting hole 9 passes through the middle of the splicing base 7.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the fixing unit 4 includes a moving groove 10, a socket 11, a limiting pin 12, a spring 13, a push plate 14, a limiting groove 15, and a top cover 16. The moving groove 10 is located in the upper part of the counterweight base 1 and is arranged symmetrically on the left and right. The socket 11 is located on the left and right sides of the middle part of the counterweight base 1 and is arranged symmetrically on the left and right. The inner diameter of the socket 11 is set to be thinner at the front end and thicker at the back end, and the diameter of the front end of the socket 11 is the same as the diameter of the limiting hole 9. The limiting pin 12 is slidably disposed in the socket 11. The spring 13 is disposed in the socket 11, with one end fixed to the limiting pin 12 and the other end fixed inside the counterweight base 1. The push plate 14 passes through the moving groove 10 and is fixed to the limiting pin 12. The push plate 14 is slidably disposed in the moving groove 10. The limiting groove 15 is located at the top of the counterweight base 1. The top cover 16 is inserted into the upper limiting groove 15 of the counterweight base 1.

[0023] In practical use, first place the counterweight seat 1 on the column 5 in the middle of the road. Then, two people slide the splicing seat 7 on the guardrail 8 back onto the dovetail seat 6. At this time, the limiting pin 12 is pushed out from the outlet of the insertion hole 11 under the elastic push of the spring 13. Then, the push plate 14 slides in the moving groove 10, thereby the push plate 14 drives the limiting pin 12 to squeeze the spring 13, thereby pushing the limiting pin 12 into the insertion hole 11, thus pushing the splicing seat 7 to the bottom of the dovetail seat 6. At this time, the upper limit hole 9 of the splicing seat 7 is aligned with the insertion hole 11. Release the push plate 1. 4. At this time, the spring 13 pushes the limiting pin 12 out of the outlet of the insertion hole 11 and inserts it into the limiting hole 9. Thus, the limiting pin 12 limits and fixes the splicing seat 7. Then, the plug on the top cover 16 is inserted into the upper limit groove 15 of the counterweight seat 1 and fixed. Then, the counterweight seat 1 is fixed to the road surface with rivets. When a vehicle collides with the guardrail 8, the material properties of the guardrail 8 will buffer the vehicle and avoid damage. At the same time, the guardrail 8 has high elasticity and high hardness, and is not easy to break, reducing replacement costs. The above is the entire process of using the municipal guardrail.
