Description
Technical field
The utility model relates to a kind of electric power tool, is specifically related to a kind of Novel ladder.
Background technology
ladder often occurs in our daily life, especially in power industry, more essential, the picture maintenance circuit is safeguarded, set up new equipment etc., all need to come work by ladder, existing ladder is two montants to be arranged and the cross bar that is fixed between montant consists of, mainly to utilize the two ends of montant as fulcrum, and ladder upper end and metope or other often can slide when supporting object contact, easily cause ladder to topple over, affect user's safety, sometimes the staff need to be with a plurality of instruments, two hands are all held instrument on ladder, can not catch ladder, the staff easily falls down, very dangerous.
Summary of the invention
The utility model for above-mentioned prior art ladder easily slide, easily topple over, unsafe problem, a kind of Novel ladder is provided, it is placed steadily, and is safe and convenient to use.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of Novel ladder, it comprises two montants parallel to each other and is fixed on cross bar between montant, described two middle parts, montant the same side all are hinged with a support bar, all be hinged with a jig corresponding with support bar below the hinge contact of two montants, described jig one side is provided with draw-in groove, and support bar top is provided with the bayonet lock corresponding with draw-in groove.
Described two support bars are expansion link, and described two montants and two support bar low sides are provided with Anti-slip cover.
Be provided with well on the cross bar of the top between described two montants.
The utility model two middle parts, montant the same side all are hinged with a support bar, support bar can stretch, according to the ladder gradient, can regulate the height of support bar, all being hinged below the hinge contact of two montants is connected to a jig corresponding with support bar, be used for blocking support bar, make ladder install firm, be difficult for tilting, the used time is not taken off jig, support bar can be amounted in montant one side, save the space; The utility model is provided with well on the cross bar of the top between two montants, be used for place tool, can make the staff vacate a hand and catch ladder, and is safer.The utility model is simple in structure, uses safety, and is easy to operate.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of Novel ladder, it comprises two montants parallel to each other 1 and is fixed on cross bar 2 between montant, two montant 1 the same side middle parts all are hinged with a support bar 3, hinge contact 6 belows of two montants 1 all are hinged and are connected to a jig 4, jig 4 one sides are provided with draw-in groove 5, support bar 3 tops are provided with the bayonet lock corresponding with jig 47, two support bars 3 are expansion link, can adjust the length of support bar 3, two montants 1 and two support bar 3 low sides are provided with between Anti-slip cover 8, two montants 2 on cross bar topmost and are provided with well 9.
When the utility model uses, first ladder is put correct position, then break support bar 3 into two with one's hands, according to the ladder gradient, adjust the length of support bar 3, make support bar 3 lower ends hold out against ground, draw-in groove with jig 4 is stuck on bayonet lock 7 again, and ladder becomes firmly, and difficult slip is toppled over; When not using, jig 4 is removed, packed up support bar 3, then the montant of support bar 3 with ladder is combined, save the space; When the staff is with a plurality of instrument, can vacate a hand and catch ladder in the instrument inserter groove 9 that wouldn't use, safer.
