[0031] Please see Figures 1-6A manual guardrail assembly for highways includes a support frame 1, a protective plate 2 on the outer side of the support frame 1, and a quick-lock device installed on the inner side of the support frame 1. The quick-lock device includes an abutment sleeve 3, an unlocking sleeve 4, an abutment frame 5, an abutment rod 6, an abutment groove 7, and an unlocking groove 8. The abutment sleeve 3 is detachably fitted onto the outer side of the abutment rod 6. The unlocking sleeve 4 is rotatably installed on the outer side of the abutment sleeve 3. One end of the abutment frame 5 is inserted into the abutment groove 7, and the other end of the abutment frame 5 is in contact with the inner wall of the unlocking groove 8. The abutment groove 7 is located on the outer side of the abutment rod 6. The unlocking groove 8 has a variable diameter structure and is located in the unlocking sleeve 4. A locking mechanism is installed on the outer side of the abutment sleeve 3. The locking mechanism includes a mating plate 9, a mating groove 10, a mating hole 11, a fixing block 12, a mating spring 13, a mating block 14, and a lock. The assembly includes a fixed sleeve 15, a movable block 16, a limiting plate 17, a limiting rod 18, a cylindrical block 19, and a linkage spring 20. The mating plate 9 is rotatably mounted on the outside of the abutting sleeve 3. A mating groove 10 is formed on the mating plate 9, and a mating hole 11 is formed at one end of the mating groove 10. The fixed block 12 is fixedly mounted on the outside of the abutting sleeve 3. The two ends of the mating spring 13 are connected to the mating block 14 and the fixed block 12. The mating block 14 is fixedly mounted on one side of the mating plate 9. The locking sleeve 15 is fitted on the outside of the abutting sleeve 3. The movable block 16 is set on one side of the unlocking sleeve 4. The limiting plate 17 is fixedly set on the limiting rod 18. The limiting rod 18 is fixedly mounted on one side of the locking sleeve 15. The cylindrical block 19 is fixedly mounted on the outside of the abutting sleeve 3. The two ends of the linkage spring 20 are respectively connected to two adjacent movable blocks 16.

[0032] Mounting brackets 21 are installed at both ends of the guard plate 2.

[0033] In this embodiment, when the protective plate 2 needs to be removed for maintenance and replacement, the protective plate 2 must first be removed. First, rotate the mating plate 9 clockwise. The mating plate 9 drives the mating hole 11 and the mating groove 10 to rotate clockwise, and the mating plate 9 also drives the mating block 14 installed on one side to rotate clockwise. Then, the mating block 14 and the fixing block 12 cooperate to compress the mating spring 13. When the mating spring 13 is compressed to its limit, the mating hole 11 just rotates to a position concentric with the limiting plate 17. Then, push the locking sleeve 15, so that the locking sleeve 15 drives the slider 22 set on the inner side to slide along the slide groove 23, and The locking sleeve 15 drives the limiting rod 18 and the two limiting plates 17 to gradually penetrate into the mating hole 11. At the same time, the locking sleeve 15 and the mating plate 9 cooperate to compress the movable spring 24. When the movable spring 24 is compressed to its limit, one of the limiting plates 17 near the locking sleeve 15 just passes through the mating hole 11 and moves to the other side of the mating plate 9. Then the mating plate 9 is released, and the mating spring 13 pushes the mating block 14 to rotate in the opposite direction. Then the mating block 14 drives the mating plate 9 to rotate in the opposite direction. Then the mating plate 9 drives the mating hole 11 and the mating groove 10 to rotate in the opposite direction, so that the limiting rod 18 enters the mating hole. In groove 10, the limiting rod 18 and a limiting plate 17 near the locking sleeve 15 cooperate to limit the locking sleeve 15 to one side of the mating plate 9, so that the locking sleeve 15 no longer limits the roller 25. Then, the unlocking sleeve 4 is rotated forward, causing the unlocking sleeve 4 to drive multiple linkage blocks 27 set on one side to rotate forward. Then, the linkage blocks 27 drive the moving block 16 to rotate forward through the linkage groove 28. Then, the moving block 16 drives the roller 25 installed on one side to move out from between the two cylindrical blocks 19. Then, the roller 25 drives the moving block 16 outward along the linkage block 27 and the linkage groove 28. The side moves, and at the same time, the moving block 16 drives the linkage spring 20 to stretch outward. At the same time, the unlocking sleeve 4 will drive the unlocking groove 8, which has a variable diameter structure, to rotate forward. Then, the return spring 26 pushes the abutment frame 5 to move outward, so that the outer wall of the abutment frame 5 is always in contact with the inner wall of the unlocking groove 8. At the same time, the other end of the abutment frame 5 is gradually pulled out from the abutment groove 7. Then, the abutment sleeve 3 and the abutment rod 6 are pulled to both sides respectively, thereby disassembling the abutment sleeve 3 and the abutment rod 6. Then, the other abutment sleeves 3 and abutment rods 6 are removed according to the above steps. Finally, the guard plate 2 can be removed.

[0034] Please see Figures 2-6 As a further implementation of the overall device: a slider 22 is fixedly provided on the inner side of the locking sleeve 15, and a groove 23 is provided on the outer side of the abutting sleeve 3, and the slider 22 slides in the groove 23.

[0035] A movable spring 24 is movably sleeved on the outer side of the limiting rod 18.

[0036] One end of the movable spring 24 is connected to the locking sleeve 15, and the other end of the movable spring 24 is in contact with the mating plate 9.

[0037] The movable block 16 has a roller 25 on one side that rotates and engages between two corresponding cylindrical blocks 19.

[0038] A return spring 26 is movably provided on the inner side of the abutment frame 5, and the other end of the return spring 26 is connected to the outer wall of the abutment sleeve 3.

[0039] Multiple linkage blocks 27 are fixedly provided on one side of the unlocking sleeve 4, and linkage grooves 28 are correspondingly provided on the inner side of the moving block 16. The linkage grooves 28 are adapted to the linkage blocks 27.

[0040] More specifically, after the maintenance and replacement of the guard plate 2 is completed, the guard plate 2 needs to be reinstalled. The guard plate 2 is then attached to one side of the support frame 1, ensuring that the pre-drilled mounting holes on the guard plate 2 and the support frame 1 are concentric. The abutment rod 6 is then passed through the pre-drilled mounting holes on both the guard plate 2 and the support frame 1 from the outside. The abutment sleeve 3 is then fitted from the inside of the support frame 1 onto the outside of the abutment rod 6. Finally, the unlocking sleeve 4 is rotated in the reverse direction, causing the unlocking sleeve 4 to drive the moving block 16 and roller 25 to rotate in the reverse direction via the linkage block 27 and linkage groove 28. Simultaneously, the unlocking sleeve 4 drives the unlocking groove 8 to rotate in the reverse direction. Then, the inner wall of the unlocking groove 8 presses against the outer wall of the abutment frame 5, causing the abutment frame 5 to be gradually pressed inward. The abutment frame 5 then presses against the inner return spring 26, while one end of the abutment frame 5 re-inserts into the abutment groove 7. When the abutment frame 5 is fully inserted into the abutment groove 7, the abutment sleeve 3 and the abutment rod 6 form a locking relationship. Then, the rotation of the unlocking sleeve 4 stops. At this point, the moving block 16 just drives the roller 25 to move between the two original cylindrical blocks 19. Then, the linkage spring 20 resets, pulling the moving block 16 to slide inward along the linkage groove 28 and linkage block 27. Then, the moving block 16 drives the roller 25 to... 5 is inserted between the two original cylindrical blocks 19, and then the mating plate 9 is rotated clockwise again, causing the mating plate 9 to drive the mating hole 11 and the mating groove 10 to rotate clockwise. The mating plate 9 also causes the mating block 14 to press against the mating spring 13. When the mating hole 11 rotates to a position concentric with the limiting plate 17, the movable spring 24 pushes the locking sleeve 15 to slide and reset along the slider 22 and the slide groove 23. Then, the locking sleeve 15 drives the two limiting plates 17 to slide and reset via the limiting rod 18. After the movable spring 24 has fully reset, the mating plate 9 is released, and the mating spring 13 pushes the mating block 14 to rotate and reset. The rear mating block 14 drives the mating hole 11 and the mating groove 10 to rotate and reset to a position that does not correspond to the limit rod 18 and the limit plate 17 through the mating plate 9. Then, the limit rod 18 and the limit plate 17 set at the top cooperate to support the locking sleeve 15 to one side of the mating plate 9. With the cooperation of the slider 22 and the slide groove 23, the locking sleeve 15 is limited, so that the locking sleeve 15 cannot slide. Then, the inner wall of the locking sleeve 15 limits the outer wall of the roller 25, so that the roller 25 and the moving block 16 cannot move outward, thereby achieving the locking and positioning of the unlocking sleeve 4, thus ensuring the stable installation of the guard plate 2 and ensuring the stable use of the equipment.

[0041] In summary, during the use or operation of the overall equipment: when it is necessary to remove the guard plate 2 for maintenance and replacement, the guard plate 2 must be removed first. First, rotate the mating plate 9 clockwise. The mating plate 9 drives the mating hole 11 and the mating groove 10 to rotate clockwise, and the mating plate 9 also drives the mating block 14 installed on one side to rotate clockwise. Then, the mating block 14 and the fixing block 12 cooperate to compress the mating spring 13. When the mating spring 13 is compressed to its limit, the mating hole 11 just rotates to a position concentric with the limit plate 17. Then, push the locking sleeve 15, so that the locking sleeve 15 drives the slider 22 set on the inner side to slide along the slide. The groove 23 slides, and the locking sleeve 15 drives the limiting rod 18 and the two limiting plates 17 to gradually enter the mating hole 11. At the same time, the locking sleeve 15 and the mating plate 9 cooperate to compress the movable spring 24. When the movable spring 24 is compressed to its limit, one of the limiting plates 17 near the locking sleeve 15 just passes through the mating hole 11 and moves to the other side of the mating plate 9. Then the mating plate 9 is released, the mating spring 13 pushes the mating block 14 to rotate in the opposite direction, and then the mating block 14 drives the mating plate 9 to rotate in the opposite direction. Then the mating plate 9 drives the mating hole 11 and the mating groove 10 to rotate in the opposite direction, so that the limiting rod 18 moves... The locking sleeve 15 is inserted into the mating groove 10. Then, the limiting rod 18 and the limiting plate 17 near the locking sleeve 15 cooperate to limit the locking sleeve 15 to one side of the mating plate 9, so that the locking sleeve 15 no longer limits the roller 25. Then, the unlocking sleeve 4 is rotated in the forward direction, so that the unlocking sleeve 4 drives the multiple linkage blocks 27 set on one side to rotate in the forward direction. Then, the linkage blocks 27 drive the moving block 16 to rotate in the forward direction through the linkage groove 28. Then, the moving block 16 drives the roller 25 installed on one side to move out from between the two cylindrical blocks 19. Then, the roller 25 drives the moving block 16 along the linkage block 27 and the linkage groove 28. Move outwards, and at the same time, the moving block 16 drives the linkage spring 20 to stretch outwards. Simultaneously, the unlocking sleeve 4 will drive the unlocking groove 8, which has a variable diameter structure, to rotate forward. Then, the return spring 26 pushes the abutment frame 5 to move outwards, so that the outer wall of the abutment frame 5 always fits against the inner wall of the unlocking groove 8. At the same time, the other end of the abutment frame 5 is gradually pulled out from the abutment groove 7. Then, the abutment sleeve 3 and the abutment rod 6 are pulled to both sides respectively, thereby disassembling the abutment sleeve 3 and the abutment rod 6. Then, follow the above steps to remove the other abutment sleeves 3 and abutment rods 6, and then remove the guard plate 2.

[0042] After the maintenance and replacement of the guard plate 2 are completed, it needs to be reinstalled. The guard plate 2 is then attached to one side of the support frame 1, ensuring that the pre-drilled mounting holes on the guard plate 2 and the support frame 1 are concentric. The abutment rod 6 is then passed through the pre-drilled mounting holes on both the guard plate 2 and the support frame 1 from the outside. The abutment sleeve 3 is then fitted from the inside of the support frame 1 onto the outside of the abutment rod 6. The unlocking sleeve 4 is then rotated in the reverse direction, causing the unlocking sleeve 4 to drive the moving block 16 and roller 25 to rotate in the reverse direction via the linkage block 27 and linkage groove 28. Simultaneously, the unlocking sleeve 4 drives the unlocking groove 8 to rotate in the reverse direction, thus unlocking the device. The inner wall of groove 8 presses against the outer wall of abutment frame 5, causing abutment frame 5 to be gradually pressed inward. Then, abutment frame 5 presses against the inner return spring 26, and at the same time, one end of abutment frame 5 is reinserted into abutment groove 7. When abutment frame 5 is fully inserted into abutment groove 7, abutment sleeve 3 and abutment rod 6 form a locking relationship. Then, the rotation of unlocking sleeve 4 stops. At this time, moving block 16 just drives roller 25 to move between the two original cylindrical blocks 19. Then, linkage spring 20 resets and pulls moving block 16 to slide inward along linkage groove 28 and linkage block 27 to reset. Then, moving block 16 drives roller 25 to lock. The plate 9 is inserted between the two cylindrical blocks 19. Then, the mating plate 9 is rotated clockwise again, causing the mating hole 11 and the mating groove 10 to rotate clockwise. The mating plate 9 also causes the mating block 14 to press against the mating spring 13. When the mating hole 11 rotates to a position concentric with the limiting plate 17, the movable spring 24 pushes the locking sleeve 15 to slide and reset along the slider 22 and the groove 23. Then, the locking sleeve 15 drives the two limiting plates 17 to slide and reset via the limiting rod 18. After the movable spring 24 has fully reset, the mating plate 9 is released, and the mating spring 13 pushes the mating block 14 to rotate and reset. The mating block 14 drives the mating hole 11 and the mating groove 10 to rotate and reset to a position that does not correspond to the limit rod 18 and the limit plate 17 through the mating plate 9. Then, the limit rod 18 and the limit plate 17 set at the top cooperate to support the locking sleeve 15 to one side of the mating plate 9. With the cooperation of the slider 22 and the slide groove 23, the locking sleeve 15 is limited, so that the locking sleeve 15 cannot slide. Then, the inner wall of the locking sleeve 15 limits the outer wall of the roller 25, so that the roller 25 and the moving block 16 cannot move outward, thereby achieving the locking and positioning of the unlocking sleeve 4, thus ensuring the stable installation of the guard plate 2 and ensuring the stable use of the equipment.
