Abstract

The utility model provides a vehicle-used folding cabin climbing ladder. The vehicle-used folding cabin climbing ladder is technically characterized in that a suspending hook and a fixing pin are fixed on an outer cabin board, and are used for fixing the folding hook ladder; the hook ladder adopts a folding structure; the upper part and the lower part of the hook ladder are connected through hook ladder hinges; a locking device is used for locking the upper part and the lower part of the hook ladder, so that the folding state of the hook ladder is guaranteed, and the hook ladder can be fixed when hooked, folded or unfolded and can be positioned when used. The vehicle-used folding cabin climbing ladder has the advantages that little space is occupied; as the folding structure is adopted, the vehicle-used folding cabin climbing ladder is shortened compared with the original straight board type ladder; the entire thickness of the folded folding hook ladder is reduced as a pedal inserting structure is adopted, and the occupied space of the cabin climbing ladder is reduced; the ladder is small, light and convenient, and is convenient to take as the ladder is shorter than the original hook ladder; the locking device prevents the folded folding hook ladder from freely unfolding, and the fixing pin enables the folding hook ladder to be tightly connected with the vehicle body when the folding hook ladder is stored, so that the folding hook ladder is prevented from falling off; the operation is simple, quick and convenient.

Description

Vehicle folding is stepped on companion-way

Technical field

The utility model relates to one and steps on companion-way, particularly a kind of folding boarding ladder.

Background technology

The application of van and shelter series products is increasingly extensive, and the chassis of selecting is also of a great variety, due to the difference of chassis height, also different to stepping on the demand of companion-way length.The common companion-way of stepping on is straight-plate-type, and the length of stepping on companion-way using on the vehicle of high chassis is excessive, high to placing space requirement, and fetches effort, operation inconvenience.

Summary of the invention

The purpose of this utility model is for above-mentioned technical deficiency, provides one to take up room little, fetches the collapsible companion-way of stepping on easy to use.

The purpose of this utility model is achieved in that and comprises: hanged hook, hanging ladder, latching device, set pin, hanging ladder folding and hanging ladder hook.It is characterized in that, hanged hook and set pin are fixed on the plate of outer cabin, the effect of fixed fold hanging ladder.Hanging ladder adopts accordion structure, and hanging ladder folding is connected two parts up and down of hanging ladder.Latching device, by the locking of two parts up and down of hanging ladder, ensures the folded state of hanging ladder.The effect of location when fixing when hanging ladder has been linked up with folding and unfolding and using.

The beneficial effects of the utility model are:

1. take up room little: adopt collapsiblely, contrast original straight-plate-type, length is dwindled.When folding, pedal cross-linking structure has reduced the thickness of tight folded hanging ladder entirety.Reduce to step on taking up room of companion-way;

2. fetch conveniently: collapsible hanging ladder is compared with original straight-plate-type hanging ladder, and small volume and less weight, because the hanging ladder that length is more original is short, fetches conveniently;

3. fixed: latching device prevents that tight folded hanging ladder from launching voluntarily in the time of folded state, hanged hook can make tight folded hanging ladder fastening being connected with car body in the time depositing with set pin, has avoided coming off of tight folded hanging ladder;

4. use simple: taking off after hanging ladder, only need open latching device, with regard to deployable use hanging ladder, simple and efficient to handle.

Brief description of the drawings:

Fig. 1 is the front view of structural representation of the present utility model

Fig. 2 is the lateral plan of structural representation of the present utility model

Fig. 3 is use view of the present utility model.

detailed description of the invention:

Below in conjunction with accompanying drawing, the present embodiment is described further:

From Fig. 1-3, hanged hook 1 and set pin 4 are fixed on the plate of outer cabin, play effect fixing and locking tight folded hanging ladder, prevent that hanging ladder from coming off from cabin body.

Hanging ladder 2 adopts accordion structure, two parts up and down of hanging ladder are connected by hanging ladder folding 5, dwindle original hanging ladder length, in the situation that ensureing tread width, reduce the width of support beam and adopted the structure of cross-linking, reduce the integral thickness after folding, reduced taking up room of tight folded hanging ladder.

Latching device 3 is made up of locking bail and locating dowel pin, locking bail is fixed on hanging ladder first half both sides, locating dowel pin is fixed on the both sides of lower part, when use, rotary locking hook makes locking bail catch on locating dowel pin, two parts up and down of hanging ladder are locked mutually, prevent that hanging ladder from launching voluntarily from folded state, play the effect that maintains folded state.

Hanging ladder folding 5 connects two parts up and down of hanging ladder, ensures that hanging ladder can launch and pack up.

Hanging ladder hook 6 is arranged on the front end of hanging ladder, positioning action when fixing and using hanging ladder.

The description of operation of tight folded hanging ladder: open set pin, hanging ladder hook is departed from from hanged hook, take off tight folded hanging ladder, unclamp hanging ladder latching device, hang in the hook of hatch door below after hanging ladder is launched into 180 °, hanging ladder uses; Otherwise operation after finishing using.

Claims

1. a folding boarding ladder, comprise: hanged hook, hanging ladder, latching device, set pin, hanging ladder folding and hanging ladder hook, it is characterized in that, hanged hook and set pin are fixed on the plate of outer cabin, the effect of fixed fold hanging ladder, and hanging ladder adopts accordion structure, hanging ladder folding is connected two parts up and down of hanging ladder, latching device, by the locking of two parts up and down of hanging ladder, ensures the folded state of hanging ladder, the effect of location when fixing when hanging ladder has been linked up with folding and unfolding and using.
