[0034] Example 1

[0035] Refer to the instruction manual Figure 1-7A foldable fence for highway maintenance engineering, comprising two oppositely arranged posts 1, the two posts 1 are connected by a telescopic structure, the distance between the two posts 1 can be controlled by the telescopic structure, so as to control the overall length of the fence, and supporting components 3 for supporting the posts 1 are installed on both sides of the posts 1, and the supporting components 3 are movably connected to the bottom of the posts 1;

[0036] A control structure for controlling the movement of the support component 3 is provided inside the column 1;

[0037] The control structure includes a sliding member 4 slidably connected to the inside of the column 1, and a plurality of longitudinally arranged supporting links 5 are rotatably connected on both sides of the column 1. One end of the supporting link 5 is slidably connected to the sliding member 4, and a limited sliding groove is provided on the sliding member 4. One end of the supporting link 5 is rotatably connected to a sliding block, and the sliding block is slidably connected inside the limited sliding groove. The other end of the supporting link 5 is rotatably connected to one side of the supporting component 3. A threaded shaft 6 threadedly connected to the sliding member 4 is rotatably connected inside the column 1, and the sliding member 4 is slidably connected up and down inside the column 1;

[0038] The threaded shaft 6 is rotated, and the threaded shaft 6 drives the sliding member 4 to slide up and down inside the column 1. When in use, the threaded shaft 6 is rotated to drive the sliding member 4 to slide upward, thereby driving the supporting link 5 close to one end of the sliding member 4 to swing upward through the sliding member 4, and the other end of the supporting link 5 swings downward. While the other end of the supporting link 5 swings downward, the supporting component 3 is pushed away from the column 1, thereby increasing the distance between the supporting component 3 and the column 1 and improving the supporting stability; when the supporting component 3 swings downward, the supporting component 3 first supports the ground, and then lifts the column 1 upward, thereby supporting the column 1 to the current position through the supporting component 3; in this way, the supporting component 3 on the column 1 is spread out so that it can stably support the column 1, thereby supporting the fence;

[0039] After use, the threaded shaft 6 is rotated in the opposite direction, and the threaded shaft 6 drives the sliding member 4 to slide downward, and drives the supporting component 3 to swing away from the ground through the supporting connecting rod 5 until the supporting component 3 and the column 1 are in contact, thereby reducing the footprint of the supporting component 3 and making the device easy to transport.

[0040] At least one support plate 7 is fixedly connected to the bottom of the support component 3; the support plate 7 is arranged to be an isosceles trapezoid; with this arrangement, when the support component 3 swings close to the ground, the support plate 7 first contacts the ground, and the stability of the support component 3 is improved by setting the support plate 7.

[0041] The telescopic structure includes two fixing frames 2, one end of which is rotatably connected to the upper ends of two posts 1, and the two fixing frames 2 are hinged by a pin shaft, and the pin shaft is installed in the middle of the two fixing frames 2, so that the two fixing frames 2 swing around the pin shaft, and the other end of the fixing frame 2 is slidably connected to the bottom of another oppositely arranged post 1. When in use, the two posts 1 are pulled away from each other, and at this time, the two fixing frames 2 swing around the pin shaft, so that the lower ends of the two fixing frames 2 slide upward, thereby increasing the length of the fence;

[0042] After use, the two posts 1 are pushed toward each other, so that the two fixing frames 2 slide downward, thereby reducing the distance between the two posts 1 and reducing the length of the fence.

[0043] A limiting structure for fixing the telescopic position is provided on the column 1; the limiting structure includes a limiting slide rail 8 fixedly connected to the column 1, the limiting slide rail 8 is installed on the side where the two columns 1 are close to each other, the sliding end of the fixed frame 2 is fixedly connected to the limiting shaft 9, the limiting shaft 9 is slidably connected to the limiting slide rail 8, a guide groove is provided inside the limiting slide rail 8, the limiting shaft 9 is slidably connected inside the guide groove, and both sides of the limiting slide rail 8 are slidably connected to the limiting plate 10, and a plurality of limiting card slots 11 cooperating with the limiting shaft 9 are provided on the limiting plate 10, and an elastic member for pushing the limiting plate 10 in the direction of the limiting shaft 9 is provided between the limiting slide rail 8 and the limiting plate 10, and the elastic member can be a compression spring. In the initial state, under the action of the compression spring, the limiting plate 10 is pushed in the direction close to the limiting shaft 9, so that the limiting card slot 11 clamps the main limiting shaft 9 to limit the position of the limiting shaft 9;

[0044] The limiting slot 11 is arranged in an arc shape, and guide fillets are arranged at both ends of the limiting slot 11. With this arrangement, when the limiting shaft 9 slides inside the limiting slide rail 8, the limiting shaft 9 first contacts the guide fillets at both ends of the limiting slot 11, thereby compressing the elastic member of the limiting plate 10 in the direction away from the limiting shaft 9, until the two columns 1 are adjusted to a suitable position, and then the limiting plate 10 is pushed to slide in the direction close to the limiting shaft 9 under the action of the elastic member, so that the limiting slot 11 clamps the limiting shaft 9.

[0045] When in use, the two posts 1 are pulled toward or away from each other, at which time the lower end of the fixing frame 2 slides upward along the limiting slide rail 8, and the limiting shaft 9 slides upward inside the limiting slide rail 8. After sliding to a suitable position, the limiting shaft 9 is inserted into the limiting slot 11, thereby limiting the two posts 1 to the current position; in actual use, the length of the fence can be adjusted according to actual needs; when transportation is required, the two posts 1 are pushed toward each other to the extreme position, thereby reducing the floor space and improving transportation efficiency.

[0046] One of the columns 1 is provided with a plurality of auxiliary support rods 12 arranged longitudinally, and the other column 1 is fixedly connected with a plurality of sliding support rods 13, and the sliding support rods 13 are sleeved on the auxiliary support rods 12; when in use, the two columns 1 are pulled toward or away from each other, and at this time, the sliding support rods 13 slide on the auxiliary support rods 12, so as to improve its stability.

[0047] A plurality of longitudinally distributed connecting shafts 14 are fixedly connected to one of the columns 1 , and a connecting sleeve 15 matching with the connecting shaft 14 is arranged on the other column 1 .

[0048] The connecting sleeve 15 is fixedly connected to the sliding plate 16, and the sliding plate 16 is slidably connected to the column 1 on the side away from the connecting shaft 14. An elastic member is installed between the sliding plate 16 and the column 1. The elastic member adopts a tension spring. In the initial state, the sliding plate 16 is pulled toward the bottom of the column 1 under the action of the tension spring.

[0049] The upper end of the sliding plate 16 is fixedly connected with a pulling plate 17 .

[0050] When two fences need to be spliced ​​together for use, pull the pulling plate 17 on one of the fences upward, thereby synchronously pulling the sliding plate 16 upward to slide. At this time, place the connecting sleeve 15 above the connecting shaft 14 on the other fence, and under the action of the tension spring, pull the sliding plate 16 toward the bottom of the column 1. At this time, the connecting sleeve 15 is sleeved on the connecting shaft 14, thereby connecting the two fences together. This arrangement makes it easy to disassemble and assemble multiple fences.

[0051] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
