The utility model fixes the card frame in the fixed frame in different hook plates by setting an adjustment component and a fixing component, thereby increasing the length of the entire guardrail, and the spring rebound can make the partition plate stuck on the outer surface of the fixed frame, so as to fix the fixed frame, and the user can also open the baffle and the lock on the fixed frame according to the needs, so as to rotate the mounting tube on the outer surface of the connecting rod, so that the baffle is closed, so as to facilitate the staff to enter and exit, and also to play a protective effect, which is not only convenient for the staff to adjust and use, but also makes the entire device more practical.
[0004] However, in the prior art, workers usually use a cart to carry maintenance tools when passing through the guardrail. The existing guardrail can only adjust the spacing between the railings to facilitate the passage of workers, while the maintenance tools carried by the workers on the cart cannot pass through. It is necessary to manually move the tools from the vehicle through the gap between the railings, which is time-consuming and labor-intensive. The practicability of the device is limited to a certain extent. Utility Model Content

When the pull plate 17 is pulled outward, the pull plate 17 drives the movable block 15 to squeeze the spring 14 through the connecting rod 16, and the insertion rod 18 is driven to move into the installation groove 13 along with the compression of the spring 14, thereby releasing the fixation of the railing, so that the railing as a whole can be flipped in a circle, which is convenient for staff to carry a cart to pass, improves the passage efficiency, and facilitates the passage of maintenance tools carried by the cart by the staff, and the sleeve 19 is hollow.
[0024] like Figure 1-4 As shown, one end of the insertion rod 18 is connected to the cross bar B6 through the insertion hole 12, and the middle part of the support rod 2 is rotatably connected to the rotating rod 3 near the upper position. One end of the rotating rod 3 is fixedly connected to the cross bar A5, and the other end of the rotating rod 3 is fixedly connected to the gear 4. The assembled railing is flipped over as a whole by the rotating rod 3, and the rotating rod 3 will synchronously drive the gear 4 to rotate when it rotates.
[0025] like Figure 1-4 As shown, a slide groove 7 is provided on the lower surface of the cross bar A5 and the upper surface of the cross bar B6, a plurality of equally spaced sliders A8 are slidably connected to the middle portion of the cross bar A5, a plurality of equally spaced sliders B9 are slidably connected to the middle portion of the cross bar B6, and both the sliders A8 and B9 slide in the slide groove 7, bolts 10 are threadedly connected to the surfaces of the sliders A8 and B9, and the sliders A8 and B9 are fixedly connected by vertical rods 11, and the bolts 10 are turned to slide the plurality of sliders A8 and B9 to both sides along the slide groove 7 to adjust the longitudinal spacing of the railings, so as to facilitate the passage of staff and make the use more convenient and efficient.

[0027] Working principle:
[0028] When in use, the guardrail is first moved to the designated area. When the staff does not carry heavy objects, they only need to reversely screw the bolt 10 to slide the multiple sets of sliders A8 and sliders B9 along the slide groove 7 to both sides to adjust the longitudinal spacing of the guardrail to facilitate the passage of the staff. When the staff carries a cart or heavy objects, they cannot pass through by adjusting the longitudinal spacing of the guardrail. At this time, the pull plate 17 is pulled outward, and the pull plate 17 drives the movable block 15 to squeeze the spring 14 through the connecting rod 16, and the compression of the spring 14 drives the insertion rod 1 8 moves toward the installation groove 13, thereby releasing the fixation of the railing, so that the railing as a whole can be turned in a circle, which is convenient for the staff to pass through. The railing is turned through the rotating rod 3, and the rotating rod 3 drives the gear 4 to rotate. When the railing is turned to a suitable angle, the threaded rod 21 is rotated, and the threaded rod 21 drives the arc plate 22 to step toward one side of the gear 4, so that the arc plate 22 and the gear 4 are abutted to limit the position, thereby preventing the staff from being hit by the railing when passing through. When not in use, only the railing needs to be reset and the insertion rod 18 is inserted into the insertion hole 12 for limiting the position.
