[0002] Highway guardrails are protective barriers installed on both sides or in the middle of highways. They serve to protect vehicles when they collide with them. After a collision, the guardrails will be damaged and deformed to varying degrees. In order to facilitate the replacement of damaged guardrails, detachable highway guardrails have emerged. Detachable guardrails usually use screws or pull blocks in conjunction with spring clips to position the guardrails and posts. This structure is convenient for disassembly and assembly, bringing convenience to maintenance personnel.

[0003] Existing detachable highway guardrails typically have screws or pull blocks installed on the outside of the guardrail for easy disassembly and assembly. However, external factors such as strong winds can easily interfere with the stability of the screws or pull blocks, leading to loosening and poor stability. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable highway guardrail to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a detachable highway guardrail, including two symmetrically arranged posts, a guardrail body between the two posts, a positioning box on one side of each post, a connecting block fixedly installed on the rear side of each post, a positioning component at the bottom of the connecting block, the bottom end of the positioning component slidably inserted into the positioning box, a sliding component slidably arranged inside the positioning box, a clamping head fixedly installed on one side of the sliding component, the other end of the clamping head slidably inserted into the positioning component, a support assembly for supporting the sliding component is also provided inside the positioning box, and an iron block is fixedly installed on one side of the sliding component.

[0006] Furthermore, the number of positioning boxes is four, and the four positioning boxes are symmetrically installed on opposite sides of the two columns.

[0007] Furthermore, a positioning groove adapted to the card head is provided on one side of the positioning component, and the side of the card head away from the slider is slidably inserted into the positioning groove. A fixing port is provided on the top of the positioning box, and the fixing port is connected to the inside of the positioning box. The bottom end of the positioning component is slidably inserted into the fixing port.

[0008] Furthermore, the support assembly includes two limiting grooves, which are symmetrically opened in the positioning box. A slider is slidably arranged in the limiting groove. A support spring is fixedly installed on one side of the slider, and the other end of the support spring is fixedly installed on the inner wall of the limiting groove. A rotating component is rotatably arranged between the slider and the sliding component.

[0009] Furthermore, a mounting base is provided on one side of the slider, a fixed base is provided on one side of the slider, and the two ends of the rotating member are respectively rotatably disposed in the mounting base and the fixed base.

[0010] Furthermore, a first pin is provided in the mounting base, a second pin is provided in the fixed base, and the two ends of the rotating component are respectively rotatably sleeved on the first pin and the second pin.

[0011] Furthermore, a telescopic rod is fixedly installed on the slider, the telescopic end of the telescopic rod is fixedly installed on the inner wall of the limiting groove, and the support spring is movably sleeved on the telescopic rod.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a detachable highway guardrail, including two symmetrically arranged posts 1, a guardrail body 2 between the two posts 1, a positioning box 3 on one side of the posts 1, a connecting block 4 fixedly installed on the rear side of the posts 1, a positioning component 5 at the bottom of the connecting block 4, the bottom end of the positioning component 5 being slidably inserted into the positioning box 3, a sliding component 6 being slidably arranged in the positioning box 3, a clamp 7 being fixedly installed on one side of the sliding component 6, the other end of the clamp 7 being slidably inserted into the positioning component 5, a support component for supporting the sliding component 6 being provided in the positioning box 3, and an iron block 8 being fixedly installed on one side of the sliding component 6;

[0021] The support assembly includes two limiting grooves 11, which are symmetrically opened in the positioning box 3. A slider 12 is slidably arranged in the limiting groove 11. A support spring 13 is fixedly installed on one side of the slider 12, and the other end of the support spring 13 is fixedly installed on the inner wall of the limiting groove 11. A rotating component 14 is rotatably arranged between the slider 12 and the sliding component 6. A mounting seat 15 is provided on one side of the slider 12, and a fixed seat 16 is provided on one side of the sliding component 6. The two ends of the rotating component 14 are respectively rotatably arranged in the mounting seat 15 and the fixed seat 16. A first pin is provided in the mounting seat 15, and a second pin is provided in the fixed seat 16. The two ends of the rotating component 14 are respectively rotatably sleeved on the first pin and the second pin.

[0022] In practice, when disassembling the guardrail body 2 from the post 1, the operator first places the electromagnet on one side of the positioning box 3. At this time, the electromagnet attracts the iron block 8, causing the slider 6 to move away from the positioning component 5. During this process, the two rotating components 14 will rotate while pushing the two sliders 12 away from each other and compressing the support spring 13. When the iron block 8 slides inside the positioning box 3 and abuts against the side wall near the placement groove 21, the locking head 7 just slides out of the positioning groove 9, thus facilitating the release of the restriction on the positioning component 5. Finally, pulling the guardrail body 2 upward will cause the guardrail body 2 and the connecting block 4 to move the positioning component. 5. Slide out of the fixing port 10 to facilitate the removal of the guardrail body 2 from the post 1. During installation, place the permanent magnet in the placement slot 21 according to the above principle, so that the iron block 8 abuts against the side wall of the positioning box 3 near the placement slot 21. Then, insert the guardrail body 2 and the positioning part 5 into the fixing port 10. Then, take the permanent magnet out of the placement slot 21 so that the clip 7 is inserted into the positioning slot 9, thus completing the positioning of the positioning part 5. In addition, the positioning structure used to connect the post 1 and the guardrail body 2 is hidden inside the positioning box 3, and the outside world is not easily affected by its normal use, so it has strong stability.

[0023] There are four positioning boxes 3, which are symmetrically installed on opposite sides of the two posts 1. The arrangement of the four positioning boxes 3 ensures that the four corners of the rear side of the guardrail body 2 are evenly stressed, thereby improving the stability and impact resistance of the guardrail body 2 during use.

[0024] See Figure 1-4 The positioning component 5 has a positioning groove 9 on one side that matches the locking head 7. The side of the locking head 7 away from the slider 6 is slidably inserted into the positioning groove 9. The top of the positioning box 3 has a fixing opening 10, which is connected to the inside of the positioning box 3. The bottom end of the positioning component 5 is slidably inserted into the fixing opening 10. This design allows the locking head 7 to be easily inserted into the positioning component 5 for positioning and also allows the positioning component 5 to be easily inserted into the positioning box 3, avoiding motion interference.

[0025] See Figure 1-4 A telescopic rod 17 is fixedly installed on the slider 12. The telescopic end of the telescopic rod 17 is fixedly installed on the inner wall of the limiting groove 11, and the support spring 13 is movably sleeved on the telescopic rod 17. This allows the slider 12 to slide along the direction of the telescopic end of the telescopic rod 17, preventing the slider 12 from deviating during sliding.

[0026] A ball bearing 18 is rotatably mounted on one side of the slider 12. The ball bearing 18 is rotatably connected in the limiting groove 11. A cavity 19 and a placement port 20 are respectively opened inside the slider 12 and on one side. The cavity 19 and the placement port 20 are connected. The ball bearing 18 is rotatably mounted in the cavity 19, and part of the ball bearing 18 protrudes from the slider 12 through the placement port 20.

[0027] In specific implementation, based on the above implementation, the movement of slider 12 can drive ball 18 to roll in limiting groove 11, which can change the sliding friction of slider 12 in limiting groove 11 to rolling friction, reducing the friction force. This not only allows slider 12 to move smoothly, but also avoids the problem of motion interference caused by debris generated by friction between slider 12 and limiting groove 11.

[0028] See Figure 1-4 The placement groove 21 and the iron block 8 are on the same horizontal line, and the bottom wall of the placement groove 21 is provided with an inclined surface 22. When the permanent magnet is placed on the placement groove 21, the permanent magnet is closest to the iron block 8, which facilitates the permanent magnet to attract the iron block 8. By setting the inclined surface 22, the debris falling into the placement groove 21 can slide out along the inclined surface 22, avoiding the accumulation of debris in the placement groove 21 and affecting the personnel's placement of the permanent magnet.

[0029] It should be noted that because permanent magnets are inexpensive and easy to carry, there will be no problem with disassembling and assembling the main body of the guardrail.

[0030] Working principle: When using the guardrail body 2, firstly, when disassembling the guardrail body 2 from the post 1, the operator places the electromagnet in the placement slot 21. At this time, the electromagnet attracts the iron block 8, causing the slider 6 to move closer to the placement slot 21. During this process, the two rotating parts 14 will rotate and push the two sliders 12 away from each other along the direction of the telescopic end of the telescopic rod 17, compressing the support spring 13. When the iron block 8 slides in the positioning box 3 and abuts against the side wall near the placement slot 21, the locking head 7 just slides out of the positioning slot 9, thus facilitating the release of the limiting position on the positioning part 5. Finally, pulling the guardrail body 2 upwards allows the guardrail body 2 and the connecting... The connecting block 4 drives the positioning component 5 to slide out of the fixing port 10, thereby facilitating the removal of the guardrail body 2 from the post 1. During installation, the permanent magnet is placed in the placement slot 21 according to the above principle, so that the iron block 8 abuts against the side wall of the positioning box 3 near the placement slot 21. Then, the guardrail body 2 is inserted into the fixing port 10 along with the positioning component 5, and the permanent magnet is taken out from the placement slot 21, so that the clip 7 is inserted into the positioning slot 9, thus completing the positioning of the positioning component 5. In addition, the positioning structure used to connect the post 1 and the guardrail body 2 is hidden inside the positioning box 3, and the outside world is not easily affected by its normal use, so it has strong stability.

[0031] During the above operation, the movement of slider 12 can drive ball 18 to roll in limiting groove 11, which can change the sliding friction of slider 12 in limiting groove 11 to rolling friction, reducing the friction force. This not only allows slider 12 to move smoothly, but also avoids the problem of motion interference caused by debris generated by friction between slider 12 and limiting groove 11. By setting inclined surface 22, the debris falling into placement groove 21 can slide out along inclined surface 22, avoiding the accumulation of debris in placement groove 21 and affecting the placement of permanent magnets.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
