Description

Safety buckle structure of ladder stand

Technical Field

The utility model relates to a building cat ladder technical field, in particular to cat ladder safety buckle structure.

Background

At the building top, there is some roofing not to have the stair can reach, for the convenience overhauls on these roofs, need set up the outer wall cat ladder, nevertheless because problem such as negligence of management, non-maintainer probably reaches the building top, climbs to above through the cat ladder, and is very dangerous, causes the accident of falling from the building easily.

The bottom end of the ladder stand in the prior art is spaced from the ground by a relatively large distance so as to prevent non-maintainers such as children from climbing the ladder stand.

The disadvantage of the prior art is that if some non-maintainers climb up the ladder by means of a short ladder, it is still possible to climb up the top of the building, and therefore the ladder of the prior art still has a great potential safety hazard.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cat ladder safety buckle structure has realized making the function that non-maintainer is difficult for climbing to the roofing top.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides a cat ladder safety knot structure, safety knot sets up on the cat ladder, safety lock and connecting piece are detained including sheltering from the panel to the safety, the cat ladder includes first perpendicular frame, second perpendicular frame and horizontal pole, a plurality of horizontal pole parallel arrangement are and all connect between first perpendicular frame and second perpendicular frame, shelter from the panel and be located the one side of keeping away from the wall body at first perpendicular frame and second perpendicular frame, one side of sheltering from the panel is through the articulated setting of vertical articulated shaft and first perpendicular frame, shelter from the panel and shelter from a plurality of horizontal poles along vertical direction, the connecting piece includes the connecting plate, fixed knot and safety lock, the connecting plate is through the articulated setting of one side that first perpendicular frame was kept away from to first vertical articulated shaft and shelter from the panel, the spliced eye has been seted up on the connecting plate, fixed knot is fixed to be set up on second perpendicular frame, fixed knot passes spliced eye and connecting plate grafting cooperation.

By adopting the technical scheme, when the roof does not need to be overhauled, the shielding panel is rotated to enable the connecting plate to be in inserting fit connection with the fixing buckle, the shielding panel shields the plurality of transverse rods along the vertical direction, and the safety lock enables the connecting plate to be incapable of being far away from the fixing buckle, so that the shielding panel is limited, non-overhaulers cannot climb along the transverse rods continuously, and the non-overhaulers cannot open the safety lock due to the fact that the non-overhaulers do not have safety lock keys, so that the shielding panel can block the non-overhaulers; when the maintainer need overhaul, the staff opens the safety lock through the key, then will shelter from the panel and rotate to the one side of keeping away from the second and erect the frame, and the staff can continue to climb to the top along the cat ladder this moment, has consequently realized the function that improves the cat ladder security.

The utility model discloses further set up to: the safety storage piece is fixedly arranged on the ladder stand, the safety storage piece is fixedly arranged on the second vertical frame, the fixing buckle is fixedly arranged in the safety storage piece, the safety lock is located in the safety storage piece, and the safety storage piece plays a role in shielding the safety lock.

Through adopting above-mentioned technical scheme, when being connected connecting plate and fixed knot through the safety lock, the safety lock is located safe storage, and safe storage plays the effect of sheltering from to the safety lock, consequently makes non-maintainer be difficult for destroying the safety lock for non-maintainer is difficult for climbing to the roof.

The utility model discloses further set up to: safe storage part is including accomodating the pole, accomodates the pole along horizontal direction fixed connection second on erecting the frame, accomodate the pole and keep away from and seted up on the vertical lateral wall that the second erected the frame and accomodate the groove, accomodate the groove and run through two vertical lateral walls that accomodate the perpendicular to second of pole and erect the frame, fixed knot fixed connection is accomodate the groove and is close to on the inside wall that the second erected the frame.

Through adopting above-mentioned technical scheme, when fixing sheltering from the panel, rotate the connecting plate, make fixed knot and spliced eye grafting cooperation, then pass fixed knot with the catch of safety lock and die the safety lock, consequently make the connecting plate can't separate with fixed knot, realized will sheltering from the fixed function of panel, and simultaneously, because the safety lock is located and accomodates the inslot, consequently, non-maintainer is difficult for destroying the safety lock with article such as knocking hammer insert to accomodate the inslot, has strengthened the connection reliability who shelters from the panel promptly, the security that has promoted the cat ladder.
