Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of passenger vehicle foldable self-locking cat ladder as shown in Fig. 1, Fig. 3, Fig. 8, comprise cat ladder body 1, the top of cat ladder body 1 is provided with the upper arm 2 mounted mutually with top luggage rail, the middle part of cat ladder body 1 and bottom position are respectively equipped with the outer brace 4 of the first outer brace 3, second leant with vehicle body, cat ladder body 1 comprises and to be hinged and can the first cat ladder 11, second cat ladder 12 of doubling laminating, and the outer brace 4 of upper arm the 2, first outer brace 3, second is all hinged and connected with cat ladder body 1 and also can doubling fits on cat ladder body 1.
Further, as shown in Figure 4, first cat ladder 11, second cat ladder 12 is connected by the first locating hinge 5, first locating hinge 5 is overall U-shaped, comprise in vertical arrange locating plate 51 and respectively perpendicular to first side plate 52 at the first locating plate 51 two ends, the end of the first cat ladder 11 and the top of the second cat ladder 12 are hinged to be respectively fixed on the first side plate 52, when cat ladder body 1 is in deployed condition, first cat ladder 11, second cat ladder 12 is in same vertical guide under the restriction of the first locating plate 51, when cat ladder body 1 is in folded state, first cat ladder 11, second cat ladder 12 respectively along clockwise direction and anticlockwise direction rotate doubling fit together.Namely the first cat ladder rotates counterclockwise and can not rotate to during the first locating plate position again, can not rotate when the second cat ladder is clockwise to the first locating plate position again, is now the deployed condition of the first cat ladder, the second cat ladder; Time folding, the first cat ladder, the second cat ladder are respectively by cw and rotate counterclockwise doubling and fit together, and namely the first cat ladder, the second cat ladder are in parastate.
Further, upper arm 2 comprises the upper arm body 21 be connected with the first cat ladder 11 top by the second locating hinge 6 and the hook 22 being arranged on upper arm body 21 end, hook 22 is weldingly connected with upper arm body 21 and mounts mutually with top luggage rail, and the second locating hinge 6 is fixedly connected with the first cat ladder 11 top.Namely one end of upper arm body and the second locating hinge are hinged and connected, and other one end of upper arm body and welding hook, for being fixedly connected with between the second locating hinge with the first cat ladder.
Further, as shown in Figure 5, Figure 6, second locating hinge 6 comprises the second locating plate 61 arranged in horizontal direction, the two ends of the second locating plate 61 are provided with the second side plate 62 respectively downward vertically, upper arm body 21 is hinged to be fixed on the second side plate 62, when upper arm 2 is in deployed condition, the included angle A of upper arm body 21 under the restriction of the second locating plate 61 between its lower surface and the first cat ladder 11 is greater than 90 degree, when upper arm 2 is in folded state, upper arm 2 rotates doubling in the counterclockwise direction and fits on the first cat ladder 11.Namely upper arm is when deployed condition, can not rotate when upper arm body is clockwise to the second locating plate position again, realizes location by the second locating plate, and namely the angle opened of upper arm is certain; Time folding, the doubling of upper arm left-hand revolution fits in the first cat ladder, is in the state paralleled with the first cat ladder.
Further, the lower surface of upper arm body 21 be also provided with the steel rope 7 both being connected between the first cat ladder 11, when upper arm 2 is in deployed condition, steel rope 7 is in tensioner state.Its stressed reliability when steel rope can ensure that upper arm and top luggage rail mount.
Further, the lower face of the second locating plate 61 is provided with the backing plate 63 of angle between adjustable upper arm 2 lower surface and the first cat ladder 11.Namely the angle between upper arm and the first cat ladder is regulated by the thickness of backing plate 63.
Further, the outer brace 4 of first outer brace 3, second is connected with the lower position of the first cat ladder 11, second cat ladder 12 respectively by the 3rd locating hinge 8, the 4th locating hinge 9, when first outer brace 3 is in deployed condition, included angle B between the upper surface of the first outer brace 3 and the first cat ladder 11 is greater than 90 degree, when first outer brace 3 is in folded state, the first outer brace 3 is rotated in a clockwise direction doubling and fits on the first cat ladder 11; When second outer brace 4 is in deployed condition, the angle C between the upper surface of the second outer brace 4 and the second cat ladder 12 is greater than 90 degree, and when the second outer brace 4 is in folded state, the second outer brace 4 is rotated in a clockwise direction doubling and fits on the second cat ladder 12.Namely the first outer brace, the second outer brace rotate counterclockwise can not rotate to during locating plate position on the 3rd locating hinge, the 4th locating hinge again, i.e. the angle that the first outer brace, the second outer brace are opened is certain.As shown in Figure 7, the structure of the 3rd locating hinge 8 is identical with the structure of the second locating hinge, just setting direction have adjusted, the structure of the 4th locating hinge and setting direction identical with the 3rd locating hinge, no longer the structure of the 3rd locating hinge, the 4th locating hinge is repeated at this.
The setting that included angle B and angle C are greater than 90 degree, because when people's first outer brace in climbing process, the second outer brace can be subject to the transverse force from cat ladder, when this angle is greater than 90 degree, it is exactly obliquely that power is transmitted to its stressed direction in the first outer brace, the second outer brace, the resultant direction of this power and the first outer brace simultaneously, the second outer brace self gravitation is oliquely downward all the time, so the first outer brace, the second outer brace would not close, also just define self-locking, bondsman can get on safely, easily.
Further, as shown in Figure 2, the first cat ladder 11 comprise uniform welding between two steel tubular beam, 111, two steel tubular beam 111 of vertically be arrangeding in parallel have many connect both the first steel pipe 112.
Further, second cat ladder 12 comprises U-shaped steel pipe fitting 121, the side lever of U-shaped steel pipe fitting 121 is welded with the second steel pipe 122 paralleled with the first steel pipe 112, the bottom of 11 two steel tubular beam in top and the first cat ladder of U-shaped steel pipe fitting 121 is connected by the first locating hinge 5.
The utility model, when folding, respectively by the first cat ladder, the second cat ladder doubling, then by upper arm, the first outer brace, the second outer brace doubling, reach after making whole cat ladder folding and minimizes, to take minimum boot compartment space, folding convenient, carrying convenience.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
