Abstract
The invention discloses a safety ladder, belonging to a climbing tool and mainly solving the problems that the traditional ladder is poor in safety and a person falls to be injured easily in use. The safety ladder comprises vertical rods and cross beams, wherein the vertical rods are provided with longitudinal wedge-shaped sliding grooves which are internally provided with sliding blocks; the sliding blocks are connected with pull ropes; the other ends of the pull ropes are fixed on locking hooks; and the locking hooks are adjustable hooks with overturning type locking pressing plates. The safety ladder disclosed by the invention has the advantages that the overturning or sideslip of the ladder is avoided, so that the personal safety of a user is protected and various accidents such as falling injury and the like are avoided.
Description
Technical field
The present invention relates to a kind of instrument of ascending a height, specifically is a kind of safety ladder.
Background technology
Ladder is generally made with bamboo and wood as a kind of apparatus of ascending a height, and supplies the people by about the rank, be used for work high above the ground, but traditional ladder generally all is to do the limit by two long thick bar, and scansorial cross bar is crossed in the centre, when being used for climbing as foothold, so the people is when upper and lower ladder, especially arrived the ladder top, because the many reasons such as discontinuity equalization, the easily outside overturning of ladder or sideslip, when serious even personnel's tumble injury occurs, there is great potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of safety ladder, this ladder have use safely, prevent the function of overturning or sideslip.
The present invention solves the technical scheme that its technical problem takes: a kind of safety ladder, comprise vertical rod and crossbeam, described vertical rod is provided with longitudinally wedge shape chute, be provided with slide block in the chute, be connected with stay cord on the slide block, the stay cord other end is fixed on the locking hook, and the locking hook is the adjustable hook with convertible locking pressure plate.
The invention has the beneficial effects as follows: the locking hook can hook fixed object; stay cord just can firmly be held ladder like this; the people can ladder overturning or sideslip not occur because of a variety of causes such as discontinuity equalizations when climbing ladder; thereby protection user personal safety; avoid occurring all kinds of accidents such as tumble injury, safe and convenient to use.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1 vertical rod, 2 crossbeams, 3 slide blocks, 4 stay cords, 5 locking hooks.
The specific embodiment
As shown in Figure 1.A kind of safety ladder comprises vertical rod 1 and crossbeam 2, and described vertical rod 1 is provided with longitudinally wedge shape chute, be provided with slide block 3 in the chute, be connected with stay cord 4 on the slide block 3, stay cord 4 other ends are fixed on the locking hook 5, and locking hook 5 is the adjustable hook with convertible locking pressure plate.
During use; ladder slightly is certain angle of inclination correctly to be placed on to ascend a height and to carry out the place of operation; but according to the upper and lower adjustment slide block of the height of permanent position 3 positions; so that locking hook 5 hooks fixed object; stay cord 4 just can firmly be held ladder like this; the people can be because ladder overturning or sideslip appear in a variety of causes such as discontinuity equalization when climbing ladder, thereby protection user personal safety avoids occurring all kinds of accidents such as tumble injury.
