Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is open mode structural representation of the present utility model.
Fig. 2 is collapsed state structural representation of the present utility model.
The specific embodiment
The a kind of folding of the present embodiment can be received formula climbing ladder apparatus basic structure as shown in Fig. 1-Fig. 2, comprise compartment 1, cat ladder, cat ladder is divided into cat ladder 2 and lower cat ladder 3, cat ladder is provided with cat ladder locking device, lower cat ladder locking device, the corresponding connection in ladder top, both sides with lower cat ladder 3 by connector respectively of the ladder lower end, both sides of upper cat ladder 2, it is fixed point that cat ladder relies on compartment 1.In the present embodiment, connector is junction plate 4, junction plate 4 has the upper and lower end face of horizontal U-shaped, its U-shaped outward opening and form hollow structure wide at the top and narrow at the bottom, interior hollow structure one side of junction plate 4 is connected with the rear portion of upper cat ladder both sides ladder respectively by screw, and opposite side upper, open end is connected with ladder top, lower cat ladder both sides respectively by rotating shaft.
Secondly, after the both sides ladder of upper cat ladder 2, upper support bar 5, the lower support bar 6 of installation are connected with compartment 1 cat ladder respectively, after the ladder of upper cat ladder both sides, Connection Block 7 is installed respectively in upper and lower parts, on Connection Block 7, by rotating shaft, connect upper support bar 5, lower support bar 6 one end, upper fixed support 8, lower fixed support 9 that upper support bar 5, lower support bar 6 other ends are installed respectively with left and right limit, compartment 1 by rotating shaft are connected, need to illustrate, lower fixed support 9 cross sections that coordinate with lower support bar 6 other ends are U-shaped, and lower support bar 6 other ends are plugged in U-shaped.
In addition, this cat ladder also must be installed cat ladder locking device, lower cat ladder locking device, upper cat ladder locking device comprises resilient pin 9-1, lockhole 9-2, and resilient pin 9-1 is positioned at the U-shaped face that removes of lower fixed support 9 with on outside, and lockhole 9-2 is positioned on the lower support bar 6 of resilient pin 9-1 cooperation; Lower cat ladder locking device comprises jam plate 10, and jam plate 10 is horizontal U-shaped, and its U-shaped blind end and ladder rear portion, lower cat ladder both sides are connected, and on U-shaped openend lateral surface, resilient pin 10-1 are installed, and on the upper cat ladder ladder coordinating, lockhole 10-2 are installed with its resilient pin 10-1; Upper cat ladder locking device and lower cat ladder locking device are symmetrically distributed respectively in the both sides of upper and lower cat ladder ladder, thus the stability while having strengthened this cat ladder locking.The locking shape of this cat ladder of specific implementation, first upwards fold lower cat ladder 3, then on, push to cat ladder 2, just because of lower fixed support 9 cross sections that coordinate with lower support bar 6 other ends are U-shaped, now utilize lower support bar 6 other ends (bottom) to be just in time plugged in U-shaped, and then pack up cat ladder 2, at this time, utilize respectively upper cat ladder locking device and lower cat ladder locking device, the resilient pin 9-1 that first operation is arranged on lower fixed support 9 inserts the lockhole 9-2 that lower support bar 6 coordinates above, and in pinning, cat ladder 2; Then operate the resilient pin 10-1 installing on jam plate 10 and insert in the lockhole 10-2 on lower cat ladder 3 ladders, pin with that lower cat ladder 3.This cat ladder just becomes the folding shape of packing up like this.
This cat ladder of specific implementation launches shape, first untie lower cat ladder 3 locking devices, unclamp the resilient pin 10-1 of lower cat ladder 3 locking use, the lockhole 10-2 that makes it to be mated departs from, naturally lower cat ladder 3 just overturns out, then the resilient pin 9-1 on lower support bar is unclamped, the lockhole 9-2 that makes it to be also mated departs from again, and upper cat ladder 2 in like manner also overturns out.This cat ladder just becomes launch shape and can use like this.Pack up with deployment step on the contrary, repeat no more.
The convenience and quickness of climbing body device in order to improve this, upper cat ladder ladder top adds one-level pedal 11, is convenient to the compartment top that safely, easily gets on and off.In addition, stability when packing up and opening and using for further this cat ladder of reinforcement is folding, upper cat ladder 2 both sides ladder middle-ends and end are provided with rubber projection 12, go up like this cat ladder 2 and lower cat ladder 3 when folding or open position, because the rubber projection 12 forming therebetween, finally plays the mutual extruding force that cushions upper and lower cat ladder.
In last this implementation process, in order to reduce car body load-bearing, upper cat ladder 2, lower cat ladder 3, upper support bar 4, lower support bar 5, junction plate 9, pedal 11 adopt the high-intensity aluminium section of lightweight; For anti-skidding, pedal 11 is punching Figured aluminium plate.
In addition to the implementation, the utility model also can have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, drop on the protection domain of the utility model requirement.
