Further, the locking structure includes a ratchet bar 150, the ratchet bar 150 is provided with two ratchet bars and is separately arranged at two sides of the inner rod body 140, two inner ratchet teeth 131 are provided at two inner side walls of the outer rod body 130, the ratchet bar 150 corresponds to the inner ratchet teeth 131 and can be meshed with the inner ratchet teeth 131, and the expansion rod 120 is prevented from being elongated after the ratchet bar 150 is meshed with the inner ratchet teeth 131.
The ratchet bar 150 is provided with a stop block 151, the inner rod body 140 is provided with a clamping groove, the stop block 151 is slidably arranged in the clamping groove along the width direction of the inner rod body 140, and the clamping groove prevents the stop block 151 from moving along the rod length of the inner rod body 140; a return spring is arranged between the ratchet bar 150 and the inner rod 140, and the return spring promotes the two ratchet bars 150 to be far away from each other; the outer rod body 130 is provided with a limit groove 132 with an open lower end, the initial stop block 151 is positioned in the limit groove 132 to prevent the ratchet bar 150 from being meshed with the inner ratchet 131, when the telescopic rod 120 stretches, the inner rod body 140 moves in a direction away from the outer rod body 130, the inner rod body 140 moves to the stop block 151 to be separated from the limit groove 132, the ratchet bar 150 moves in a direction close to the inner ratchet 131 under the action of a reset spring and is meshed with the inner ratchet 131, the ratchet bar 150 is meshed with the inner ratchet 131 to prevent the telescopic rod 120 from being shortened, and when one of the surrounding baffles 100 falls down, the telescopic rod 120 provides reliable support for the surrounding baffle 100 which does not fall down.
Fig. 1 and fig. 2 are the mounted state of the surrounding baffles 100, at this time, two adjacent surrounding baffles 100 are connected end to end, and the clamping blocks 104 on the previous surrounding baffle 100 are clamped in the connecting slots 1011 on the next surrounding baffle 100, so as to realize the connection of the surrounding baffles 100 in the width direction, and the width direction of the surrounding baffles 100 corresponds to the left-right direction in the figure. The first moving post 260 and the second moving post 270 are inserted into the telescopic rod 120 to thereby achieve relative locking of the position of the baffle 100 in the thickness direction. Initially, under the action of the first compression spring 240, the first moving columns 260 of the two adjacent surrounding baffles 100 respectively extend into the holes at the upper ends of the telescopic rods 120 by half a distance, and under the action of the second compression spring 250, the second moving columns 270 of the two adjacent surrounding baffles 100 respectively extend into the holes at the lower ends of the telescopic rods 120 by half a distance.
When encountering windy weather, the windward side of the enclosure plate 100 blocks the wind, and the influence on the construction area inside the enclosure plate 100 is avoided. When the wind reaches a preset value, the wind blows the movable plate 110 through the plurality of distributed conical ventilation holes 102 on the surrounding baffle 100 to enable the movable plate 110 to move in a direction away from the surrounding baffle 100, the movable plate 110 moves to drive the conical wind shielding block 111 to move so as to enable the conical ventilation holes 102 to be opened by a certain size, the conical ventilation holes 102 and the exhaust holes 115 form a wind passing channel after being opened, and the wind can smoothly pass through the surrounding baffle 100 and the movable plate 110, so that the acting force of the wind on the surrounding baffle is reduced.
If the wind force is large at the position of a certain enclosure plate 100, the enclosure plate 100 is insufficient to resist the wind force impact and has a tendency to topple, and the moving plate 110 corresponding to the enclosure plate 100 moves more than the moving plate 110 corresponding to the adjacent enclosure plate 100. Taking the tendency of the middle baffle 100 among the three baffles 100 to topple as an example, as shown in fig. 1, 2 and 9; in fig. 6, the left side of the telescopic rod 120 corresponds to the baffle plate 100 with a larger tilting tendency, and the right side of the telescopic rod 120 corresponds to the baffle plate 100 with a smaller tilting tendency.
The moving plate 110 moves to drive the first rack 112 and the second rack 114 to synchronously move; the first rack 112 moves to drive the first gear 200 to rotate, the first gear 200 drives the first screw 201 to rotate, the first screw 201 rotates to drive the first push plates 220 to move, two first push plates 220 on the same moving plate 110 are close to each other, that is, the first push plates 220 move in a direction away from the telescopic rod 120, and the first pressure springs 240 are loosened; the second rack 114 moves to drive the second gear 210 to rotate, the second gear 210 drives the second screw 211 to rotate, the second screw 211 rotates to drive the second push plate 230 to move, and two second push plates 230 on the same moving plate 110 are far away from each other, that is, the second push plate 230 moves towards the direction approaching the telescopic rod 120, and the second compression spring 250 compresses. Since the movement amount of the moving plate 110 corresponding to the surrounding plate 100 with a large tilting tendency (the surrounding plate 100 at the middle position) is larger than the movement amount of the moving plate 110 corresponding to the surrounding plate 100 at the two sides, the movement amount of the moving plate 110 at the middle position is larger, the movement distances of the corresponding first push plate 220 and the corresponding second push plate 230 are also larger, the loosening amount of the first compression spring 240 (the left side in fig. 6) corresponding to the surrounding plate 100 at the middle position is larger, the loosening amount of the first compression spring 240 (the right side in fig. 6) corresponding to the surrounding plate 100 at the two sides is smaller, and the first moving column 260 corresponding to the surrounding plate 100 at the two sides moves the first moving column 260 corresponding to the middle surrounding plate in the direction away from the corresponding telescopic rod 120 under the action of the first compression spring 240, so that the first moving column 260 corresponding to the middle surrounding plate is gradually separated from the telescopic rod 120.
Similarly, the movement amount of the second push plate 230 on the middle surrounding baffle 100 is larger than the movement amount of the second push plate 230 on the surrounding baffles 100 at the two sides, the compression amount of the second compression springs 250 (at the left side in fig. 6) corresponding to the surrounding baffles 100 at the middle position is large, the compression amount of the second compression springs 250 (at the right side in fig. 6) corresponding to the surrounding baffles 100 at the two sides is small, and the second moving columns 270 corresponding to the surrounding baffles 100 at the middle position move the second moving columns 270 corresponding to the surrounding baffles at the two sides in a direction away from the corresponding telescopic rods 120 under the action of the second compression springs 250, so that the second moving columns 270 corresponding to the surrounding baffles at the two sides are gradually separated from the telescopic rods 120. Thus, the wind difference between the middle baffle 100 and the two side baffles 100 increases to a preset value, the first moving column 260 on the middle baffle 100 is completely separated from the corresponding telescopic rod 120, the second moving column 270 on the two side baffles 100 is completely separated from the corresponding telescopic rod 120, that is, the upper ends of the telescopic rods 120 are connected with the two side baffles 100, the lower ends of the telescopic rods 120 are connected with the middle baffle 100, and after the middle baffle 100 is blown down by wind, as shown in fig. 9, the telescopic rods 120 on two sides of the middle baffle 100 are equivalent to a bracket to provide support for the two side baffles 100, so that the two side baffles 100 are more stable.
Meanwhile, the inner rod 140 of the telescopic rod 120 drives the ratchet bar 150 to synchronously move when moving outwards relative to the outer rod 130, and initially the ratchet bar 150 is not stretched out to be meshed with the inner ratchet 131 due to the limit of the limit groove 132 on the outer rod 130 by the stop block 151 on the ratchet bar 150, until the ratchet bar 150 is ejected out and meshed with the inner ratchet 131 under the action of the reset spring after the ratchet bar 150 moves to a blocking position along with the inner rod 140 and is separated from the outer rod 130, after the ratchet bar 150 is meshed with the inner ratchet 131, the telescopic rod 120 cannot be shortened, and after the surrounding baffle 100 at the middle position is reversed, the support formed by the telescopic rod 120 supports the two surrounding baffles 100 more firmly and reliably.
After the wind force is reduced, the manual control ratchet bar 150 is disengaged from the inner ratchet 131, and then the poured skirt 100 can be lifted.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
