Detailed Description

The technical scheme of the utility model is described in detail below through the drawings, but the protection scope of the utility model is not limited to the embodiments.

Referring to fig. 1 to 4, the movable folding pipe well opening fence protecting device comprises a movable folding protecting frame, wherein the folding protecting frame is composed of at least 4 vertical rods 1 which are symmetrical in front, back, left and right, and at least 2X-shaped movable cross rods 2. Each vertical rod is provided with a guide rail groove 4, the upper end of one X-shaped movable cross rod 2 in the front and rear adjacent two vertical rods 1 is hinged with the guide rail groove 4 through a guide wheel, and the lower ends of the other two connecting rods are hinged together through a fixed pin shaft. The lower part of each vertical rod 1 is provided with a fixing hole for installing a fixing pin shaft, and the upper part of each vertical rod 1 is also provided with a guide rail groove 4 for a guide wheel to pass through. As shown in fig. 1, the guide rail groove extends along the up-down direction, and the guide wheel can slide up and down along the guide rail groove 4, so that the included angle of the X-shaped movable cross rod 2 is changed, and the front and rear adjacent vertical rods are far away from or close to each other, so that the folding protection frame is unfolded or folded. The length of the guide rail groove 4 determines the maximum opening angle of the X-shaped movable link, i.e., the extent to which the folding guard frame as a whole can be unfolded and folded.

In order to facilitate the movement of each vertical rod 1 and the unfolding and folding of the folding protection frame, a movable pulley 7 is arranged at the bottom of each vertical rod 1. The whole unfolding, folding and moving of the folding protective frame is performed by means of the moving pulleys 7. Preferably, the material of the movable pulley 7 is polyurethane castor or nylon castor. As shown in fig. 1 and fig. 2, in order to facilitate the whole push-pull movement of the folding protection frame, the front end upright rod 9 of the folding protection frame is provided with the plate type protection rail 6 which is fixed with the symmetrical front end upright rod 9 to form a square shape, and one side of the plate type protection rail is pushed to drive the other symmetrical group, so that the folding protection frame is folded, unfolded, folded and moved in the sense.

Further, as shown in fig. 1, 3 and 4, after the complete folding protection frame is formed, 3 circular holes are left on one side of the end upright rod 8 of the folding protection frame, which is provided with the L-shaped connecting plate 5,L, and the end of the folding protection frame is fixed on a wall body by fixedly connecting the expansion bolts with the structural wall body, so that the end of the folding protection frame cannot move along with the expansion of other vertical rods at the front end. The head end of the folding protection frame is provided with a plate type protection railing, the plate type protection railing 6 is arranged on two vertical rods which are bilaterally symmetrical, and when the whole folding protection frame is moved to open, a square space of a hole is formed by enclosing.

As shown in figure 1, a dense mesh net, a safety warning sign and the like can be hung at the hook 3 at the upper end of each upright pole 1 according to the actual requirements of the site, so that the effect of enclosing and warning is realized, and the dense mesh net can be unfolded or folded along with a folding frame after being fixed on the upright pole 1.

While the utility model has been shown and described with reference to certain preferred embodiments thereof, it is not to be construed as limited to the utility model itself, but various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
