Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to specific embodiments and fig. 1 to 4.

Embodiment one:

the utility model provides a building safety protection railing, includes a folding rail guard 2, rail guard 2 includes two support horizontal poles 21 that are parallel to each other, two be equipped with a plurality of connecting rods 23 that are parallel to each other between the support horizontal pole 21, support horizontal pole 21 with square tube material is all used to connecting rod 23, and the square tube size that supports horizontal pole 21 used is obviously greater than the square tube size that connecting rod 23 used because support horizontal pole 21 plays main support fixed action.

Preferably, both ends of the connecting rod 23 are rotatably connected with the two support cross rods 21 through a hinge 22 structure so as to realize the folding function of the guard rail 2, specifically, the hinge 22 comprises a top plate, a left side plate, a front side plate and a rear side plate, the four metal plates with the same size are welded to form a cube structure with an opening at the right side and the bottom, corresponding shaft holes are formed in the centers of the front side plate and the rear side plate, a rotating shaft 24 is arranged in the shaft holes, the rotating shaft 24 can freely rotate relative to the front side plate, the hinge 22 is fixed at the bottom of the support cross rod 21 above, shaft holes are formed in both end sides of the connecting rod 23, the connecting rod 23 is sleeved on the rotating shaft 24 by the shaft holes and is rotatably connected with the rotating shaft 24, and the connecting rod 23 can only move to the vertical state along the horizontal right state due to the fact that the right side of the hinge 22 lacks the sealing of the plate at the bottom.

The rotation direction of the connecting rod 23 relative to the support rail 21 above the connecting rod 23 is opposite to the rotation direction of the connecting rod 23 relative to the support rail 21 below the connecting rod, specifically, the hinges 22 at the bottom end of the connecting rod 23 and the hinges 22 at the top end are arranged symmetrically according to the center, so that the top end of the connecting rod 23 can rotate anticlockwise along the rotation axis 24 and approach to the support rail 21 at the upper part, while the lower end of the connecting rod 23 rotates anticlockwise along the rotation axis 24 and approaches to the support rail 21 at the lower part, thus, as the connecting rod 23 rotates, the connecting rod 23 gradually tends to be parallel to the support rail 21, because the distance between two adjacent hinges 22 on the support rail 21 is greater than the length of the connecting rod 23, the connecting rod 23 can be completely folded to be parallel to the support rail 21, as shown in fig. 3, and after being folded, the transportation of the device can be facilitated without occupying too much transportation space.

The hinge 22 positioned at the left upper part of the guard rail 2 is provided with a fixing hole which is positioned at the right lower part of the front side plate and positioned on the diagonal line of the front side plate, the position of the fixing hole can ensure that the connecting rod 23 can be overlapped with the fixing hole in the folded state and the unfolded state, the fixing hole is internally provided with a fixing pin 221, the upper end of the connecting rod 23 positioned at the leftmost side is provided with two fixing pin holes which are respectively positioned at the overlapping part of the connecting rod 23 and the fixing hole when the guard rail 2 is completely unfolded and the overlapping position of the connecting rod 23 and the fixing hole when the guard rail 2 is completely folded, so that when the guard rail 2 is completely unfolded or completely folded, the hinge 22 and the connecting rod 23 can be fixed by inserting the fixing pin 221, thereby realizing the fixation by penetrating the connecting rod 23 and the hinge 22 through one fixing pin 221 when the guard rail 2 is kept unfolded or folded state, namely, the connecting rod 23 is vertical or parallel to the supporting cross rod 21, and the guard rail is convenient to store.

The two end sides of the supporting cross bars 21 are provided with oblong holes 211 along the horizontal direction, the oblong holes 211 can be conveniently installed, the requirement on installation accuracy is small, a screw rod 21 is arranged in each oblong hole 211, one end of each screw rod 3 is pre-embedded into a high-altitude side shear wall 1 and can serve as a fixed end for installation of the protective fence 2, the protective fence 2 is provided with high-altitude side positions through four screw rods 3, each screw rod 3 is a T-shaped screw rod, the T-shaped head end of each screw rod 3 is pre-embedded into the shear wall 1, the other end of each screw rod 3 extends out of the shear wall 1, the T-shaped head is embedded into concrete, the contact area between each screw rod 3 and the concrete can be increased, the screw rods 3 are prevented from being pulled out when the stress is excessive, the installation stability of the protective fence 2 is affected, potential safety hazards are caused, the screw rods 3 are connected with conical bolts 31 in a threaded mode, the heads of the conical bolts 31 and the screw rods 3 are pre-embedded into the wall 1 together, the joint strength of the screw rods 3 and the shear wall 1 is improved, the gaskets 32 and 33 are arranged on the screw rods 3, the support heads of the screw rods 3 and the shear walls 21 are tightly connected with the long-shaped bolts 33, and the gaskets can be assembled on the long-shaped bolts 33.

Other than the technical features described in the specification, all are known to those skilled in the art.

In the present utility model, the terms "upper", "lower", "left", "right", "front" and "rear" are relative positions used for convenience in describing the positional relationship, and thus are not to be construed as limiting the scope of protection as absolute positions.

The foregoing is merely illustrative and explanatory of the utility model, as it is well within the scope of the utility model as claimed, as it relates to various modifications, additions and substitutions for those skilled in the art, without departing from the inventive concept and without departing from the scope of the utility model as defined in the accompanying claims.
