One end of the fence loading rack structure 1 is fixedly connected to the adjustment and prompt structure 2, and the fence enclosure structure 3 is arranged inside the fence loading rack structure 1.

[0026] The fence loading rack structure 1 includes a loading rack 4, a guiding groove 5, a bolt 6, and a first fitting block 7. A plurality of guiding grooves 5 are formed inside the loading rack 4. One side of the loading rack 4 is fixedly connected to the first fitting block 7, and the bolt 6 is arranged inside the first fitting block 7.

[0027] A mating lock groove 8 is formed inside the first fitting block 7, and a first fitting hole 9 is also formed inside the first fitting block 7. The other side of the loading rack 4 is fixedly connected to a second fitting block 10, and a second fitting hole 11 is formed inside the second fitting block 10.

[0028] The second fitting block 10 of one loading rack 4 and the mating lock groove 8 of another loading rack 4 are in clearance fit. The diameter of the second fitting hole 11 is the same as that of the first fitting hole 9, and both the inside of the first fitting hole 9 and the inside of the second fitting hole 11 are threadedly connected to the bolt 6.

[0029] During use, according to the length to be enclosed, two fence loading rack structures 1 are assembled. During the assembly process, the second fitting block 10 is inserted into the inside of the mating lock groove 8 so that the first fitting hole 9 corresponds to the second fitting hole 11. At this time, through the threaded connection of the bolt 6 with the first fitting hole 9 and the second fitting hole 11, the bolt 6 penetrates through the first fitting block 7 and the second fitting block 10 to complete the fixed assembly.

[0030] The adjustment prompt structure 2 includes a positioning mounting frame 12, an extended mounting plate 13, a first torque output structure 14, a driving gear shaft 15, a driven gear 16, a transmission shaft 17, a central mounting column 18, a first state prompt plate 19 and a second state prompt plate 20. One end of the mounting frame 4 is fixedly connected to the positioning mounting frame 12, one side of the positioning mounting frame 12 is fixedly connected to the extended mounting plate 13, one side of the extended mounting plate 13 is fixedly connected to the first torque output structure 14 by screws, the output end of the first torque output structure 14 is fixedly connected to the driving gear shaft 15, the inner side of the positioning mounting frame 12 is rotatably connected to the transmission shaft 17, one side of the transmission shaft 17 is fixedly connected to the driven gear 16, one end of the driving gear shaft 15 is meshed with the driven gear 16, the outer side of the transmission shaft 17 is fixedly connected to the central mounting column 18, one end of the central mounting column 18 is fixedly connected to the first state prompt plate 19, and the other end of the central mounting column 18 is fixedly connected to the second state prompt plate 20.

[0031] By pasting words indicating normal passage on the first state prompt plate 19 and pasting words indicating that passage is prohibited during the test on the second state prompt plate 20, the first state prompt plate 19 and the second state prompt plate 20 form prompts of different states.

[0032] During the test, the first torque output structure 14 is controlled to drive the driving gear shaft 15 to complete the rotation, and the meshing connection between the driving gear shaft 15 and the driven gear 16 is utilized to make the driven gear 16 complete the rotation under the driving and driving of the driving gear shaft 15, and the driven gear 16 is utilized to drive the transmission shaft 17 to complete the rotation, and the transmission shaft 17 is utilized to drive the central carrying column 18 to rotate synchronously, thereby driving the first state prompt plate 19 and the second state prompt plate 20 to adjust the angle, so that the second state prompt plate 20 is located at the end away from the carrying frame 4, thereby achieving the prompting effect.

[0033] The fence closing structure 3 includes a guide assembly block 21, a power carrying block 22, a second torque output structure 23, a toggle gear shaft 24, a toggle gear shaft 24, a rack 25, a transmission push plate 26 and a lifting fence 27, and the lifting fence 27 passes through the guide groove 5 and is slidably connected to the guide groove 5.

One side of the transmission push plate 26 is fixedly connected with a lifting fence 27. The lifting fence 27 includes a plurality of lifting rods, and the lifting rods are arranged corresponding to the guiding grooves 5.

[0035] During the test, control the second torque output structure 23 to drive the shifting gear shaft 24 to complete a clockwise rotation. By using the meshing connection between the shifting gear shaft 24 and the rack 25, the rack 25 is driven by the shifting and guiding of the shifting gear shaft 24 and the guiding fitting block 21, so that the rack 25 drives the transmission push plate 26 and the lifting fence 27 to descend, completing the enclosure of the carrying frame 4. After the test, control the second torque output structure 23 to drive the shifting gear shaft 24 to complete a counterclockwise rotation, thereby forming the upward opening of the lifting fence 27.

[0036] Through the design of the fence-fitted carrying frame structure, the device is convenient for forming a convenient fitting and use during the use process, so as to form a longer-distance fence. Through the design of the adjustment prompt structure, the device is convenient for adjusting and carrying two different state prompt boards, so as to form a warning for prohibiting entry during the test.
