[0018] See also Figure 1-4 ,

[0019] Embodiment 1: A highway construction safety fence includes a base 1, a support rod 2, and a barrier rod 3. The number of the base 1, the support rod 2, and the barrier rod 3 is two. The interior of the two bases 1 is hollow and the upper surface is provided with a through hole matching the support rod 2. A bidirectional screw 4 is rotatably connected between the inner side walls of the two bases 1. Two screw sleeves 5 are threadedly sleeved on the surface of each bidirectional screw 4. A splint 7 is fixedly connected to the surface of each screw sleeve 5. Two mounting blocks 8 are fixedly connected to the opposite sides of the two support rods 2. Both ends of the two barrier rods 3 are fixedly connected with an insert block 9. The surface of each mounting block 8 is provided with a slot 10 matching the insert block 9. A plurality of protective rods 11 are arranged between the two barrier rods 3.

[0020] Example 2: The difference between this example and Example 1 is that, there are sliding rods 12 fixedly connected between the inner side walls of the two bases 1, and two sliding sleeves 22 are slidably sleeved on the surface of each sliding rod 12. Each sliding sleeve 22 is fixedly connected to the corresponding splint 7, which is convenient for limiting the movement of the splint 7 and enabling it to better clamp and fix the support rod 2.

[0021] Embodiment 3: The difference between this embodiment and embodiment 1 is that a card slot 13 is provided on the surface of each insertion block 9, a movable slot 14 is provided on the upper surface of each mounting block 8, a card rod 15 is slidably sleeved inside each movable slot 14, and a spring 16 is sleeved on the top of each card rod 15. The card rod 15 matches the card slot 13, which facilitates the quick installation and disassembly of the blocking rod 3.

[0022] Example 4: The difference between this example and Example 1 is that, the upper and lower ends of each protective rod 11 are fixedly connected with a screw rod 17, and the opposite sides of the two blocking rods 3 are rotatably installed with multiple threaded sleeves 18 matching the screw rod 17. The protective rod 11 is installed between the two blocking rods 3 through the screw rod 17 and the threaded sleeve 18, which facilitates the rapid installation and disassembly of the protective rod 11.

[0023] Example 5: The difference between this example and Example 1 is that, the inner bottom walls of the two bases 1 are provided with positioning grooves 19, which match the support rods 2, and the surfaces of the two splints 7 are fixedly connected with a group of insertion rods 6, and the two side surfaces of the two support rods 2 are provided with two fixing grooves 21 that match the insertion rods 6, which further position and fix the support rods 2 to make them more stable.

[0024] Example 6: The difference between this example and Example 1 is that the two side surfaces of the two bases 1 are fixedly connected with mounting plates 20, and the surfaces of the two mounting plates 20 are provided with mounting holes, which facilitate the fixed installation of the enclosure at the location that needs protection.

[0025] In summary, when the highway construction safety fence is used, the support rod 2 is inserted into the through hole on the base 1 and inserted into the inside of the positioning groove 19, and then the two screw sleeves 5 and the clamping plate 7 are driven to move by rotating the bidirectional screw 4, and the support rod 2 is clamped and fixed by the clamping plate 7. At the same time, the insertion rod 6 is inserted into the inside of the fixing groove 21 for further fixation, and then multiple protective rods 11 are installed between the two blocking rods 3, and the protective rod 11 and the two blocking rods 3 are fixed and installed, and then the two clamping rods 15 on the two mounting blocks 8 are pulled upwards, and then the two ends of the two blocking rods 3 are clamped. The plug block 9 is inserted into the slot 10 on the mounting block 8, and then the card rod 15 is loosened so that it can be inserted into the card slot 13 on the plug block 9 under the elastic force of the spring 16, and the two baffle rods 3 are fixedly installed on the support rod 2, and then the other support rod 2 is installed at the other end of the two baffle rods 3 in the same way to complete the assembly of the enclosure. When disassembling, only the above operation needs to be performed in reverse, which is convenient and quick. The enclosure can be quickly installed and disassembled during use, which is convenient for transportation and carrying, and it is also convenient to replace damaged parts and easy to use.
