Gears are fixedly sleeved on the outer walls of both ends of the drive shaft, and the two gears mesh with two racks, respectively. Two ratchet wheels are fixedly sleeved on the middle of the outer wall of the drive shaft, with the arc-shaped surface of the ratchet wheels facing downwards. Below the two ratchet wheels is a fixed plate, which is fixedly connected to the front side wall of the enclosure. The front end of the fixed plate is inclined upwards, and the top of the fixed plate has several pull rods, which are equidistantly distributed on the left and right. The bottom end of the pull rods passes through the bottom of the fixed plate and slides with the fixed plate. A retaining plate is fixedly connected between the top ends of the pull rods, and the top end of the retaining plate engages with the two ratchet wheels. Springs are slidably sleeved on the outer walls of the pull rods, and the two ends of the springs abut against the bottom end of the retaining plate and the top end of the fixed plate, respectively.

[0018] like Figure 1-6 As shown: A green building construction protective fence includes a fence panel 1. Posts 2 are fixedly connected to both the left and right ends of the fence panel 1. Two fixing seats 3 are fixedly connected to the opposite side walls of the two posts 2. A connecting block 4 is located between the two fixing seats 3 on the left side. A T-slot 5 is formed on the left side wall of the connecting block 4, and the top of the T-slot 5 is through. A connecting block 6 is located between the two fixing seats 3 on the right side. A T-block 7 is fixedly connected to the right side wall of the connecting block 6. The T-block 7 and the T-slot 5 are slidably inserted into each other. Connecting posts 8 are fixedly connected to the top and bottom of the connecting blocks 4 and 6, respectively. The upper and lower connecting posts 8 are rotatably connected to the upper and lower fixing seats 3, respectively. A limiting groove 9 is formed on the top of the fence panel 1. The left and right ends of the limiting groove 9 protrude in a U-shape. The inner side of the limiting groove 9 is open. The panel has a strip 10, with limiting grooves 9 on both sides of the strip 10 slidingly connected. Several fixing posts 11 are fixedly connected to the bottom of the strip 10, and the fixing posts 11 are evenly distributed on the left and right. The bottom left and right ends of the strip 10 are fixedly connected to racks 12, with the teeth of the racks 12 facing forward. The opposite sidewalls of the two racks 12 are fixedly connected to limiting strips 13, which are inside the limiting grooves 9 and are slidably engaged with the limiting grooves 9. The top center of the strip 10 is fixedly connected to a handle 14. The upper part of the front sidewall of the panel 1 has a fixing hole 15, which extends to the left and right and communicates with the limiting grooves 9. A limiting mechanism is installed in the fixing hole 15. The fixing posts 11 and the bottom of the racks 12 are fixedly connected to the lower strip 25.
[0019] The limiting mechanism includes a drive shaft 16 and gears 17. The drive shaft 16 is located inside the fixing hole 15, and its left and right ends are rotatably connected to the inner walls of the left and right ends of the fixing hole 15, respectively. Gears 17 are fixedly sleeved on the outer walls of both ends of the drive shaft 16, and the two gears 17 mesh with the two racks 12, respectively. Two ratchet wheels 18 are fixedly sleeved on the middle of the outer wall of the drive shaft 16, with the arc-shaped surface of the ratchet wheels 18 facing downwards. Below the two ratchet wheels 18 is a fixing plate 19, which is fixedly connected to the front side wall of the enclosure 1. The front end of the fixing plate 19 is inclined upwards, and the top of the fixing plate 19 has several pull rods 20. The pull rods 20 are positioned to the left and right of the front end of the enclosure 1. The bottom ends of the pull rods 20 extend through the bottom of the fixing plate 19 and are equidistantly distributed on the right. The pull rods 20 and the fixing plate 19 are slidably engaged. The top ends of the pull rods 20 are fixedly connected to the clamping plate 21, and the top ends of the clamping plate 21 are engaged with two ratchet wheels 18. The outer wall of the pull rods 20 is slidably sleeved with springs 22. The two ends of the springs 22 abut against the bottom end of the clamping plate 21 and the top end of the fixing plate 19, respectively. The bottom ends of the pull rods 20 are fixedly connected to the handles 23. The outer side of the fixing hole 15 has a protective shell 24. The upper part of the protective shell 24 is fixedly connected to the front side wall of the enclosure 1, and the two ends of the protective shell 24 are fixedly connected to the outer walls of the columns 2 on both sides, respectively.
[0020] During installation, the T-slot 5 of the connecting block 1 4 on the left post 2 is inserted into the T-block 7 of the connecting block 2 6 on the right post 2 to connect the two fences. At the same time, the connecting posts 8 at the top and bottom of the connecting blocks 1 4 and 2 6 are rotatably connected to the nearby fixed seats 3 to ensure the flexibility of the connection and complete the assembly of the fence module.
[0021] Disassembly can be performed by reversing the operation and pulling the T-block 7 out of the T-slot 5 to quickly disassemble the fence module.
[0022] When it is necessary to raise the height of the protective fence, the operator holds the handle 14 and pulls it upward. The handle 14 drives the strip 10 to rise, and several fixed posts 11 at the bottom of the strip 10 rise accordingly. At the same time, the racks 12 at the left and right ends of the bottom of the strip 10 also move upward.
[0023] When the rack 12 moves upward, it meshes with the gears 17 that are fixedly sleeved on the outer walls of both ends of the drive shaft 16, causing the drive shaft 16 to rotate. The two ratchet wheels 18 in the middle of the outer wall of the drive shaft 16 rotate accordingly. Because the clamping plate 21 engages with the ratchet wheels 18 under the action of the spring 22, the ratchet wheels 18 can only rotate in one direction, thus ensuring that the rack 12 can only move upward, realizing the rise of the strip 10 and the fixed post 11, thereby increasing the height of the protective fence.
[0024] When the strip 10 rises to the appropriate height, the engagement between the ratchet 18 and the clamping plate 21 prevents the drive shaft 16 from rotating in the opposite direction, thereby preventing the rack 12 from descending and fixing the height of the strip 10, which in turn fixes the height of the protective fence.
[0025] If it is necessary to lower the fence, the operator holds the handle 23 and pulls it downwards. The handle 23 drives the pull rod 20 to move downwards, and the pull rod 20 drives the locking plate 21 to move downwards, so that the locking plate 21 disengages from the ratchet 18. At this time, under the action of gravity, the strip 10, the fixed post 11 and the rack 12 can be lowered, thereby reducing the height of the protective fence. After releasing the handle 23, under the action of the spring 22, the locking plate 21 moves upwards and re-engages with the ratchet 18 to reset.
