Specific embodiment

The technical solution of the utility model is described in further detail with reference to the accompanying drawing.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of couchette contraction ladder, including mounting plate 1, mounting hole 2, fixed pole 3, lever 4, rotating bar 5 and cross bar 6.

Wherein, the two sides of mounting plate 1 are provided with mounting hole 2, whole device can be horizontally fixed on bed board by mounting hole 2 The lower section of side, it is preferred that be also equipped in fixed pole 3 for fixed through-hole, whole device can in this way installed Stronger, safety is higher when use.

Wherein, as shown in Figure 1, Figure 2, Figure 3, Figure 4, it is fixedly installed fixed pole 3 on the front side both sides of mounting plate 1, two fixed Bar 3 is parallel to each other and both perpendicular to mounting plate 1, likewise it is preferred that, fixed pole 3 and mounting plate 1 are an integral structure setting, this The fastness of sampling device is more preferable, and two fixed poles 3 are symmetrical set about the centre of mounting plate 1, and the balance of this sampling device is more It is good.

Wherein, sliding slot 7 is provided on the medial surface of two fixed poles 3, the lateral surface of lever 4 is fixedly installed slide plate 8, passes through The sliding slot 7 being arranged in fixed pole 3 and the slide plate 8 being arranged in lever 4, together with fixed pole 3 is slidably connected with lever 4, meanwhile, it is fixed Sliding connection structure between bar 3 and lever 4 is self-locking type sliding connection structure, and such security performance is more preferable, uses more Add conveniently；When specifically used, by the sliding between fixed pole 3 and lever 4, extending outwardly and inwardly receiving for ladder may be implemented Contracting, meanwhile, the maximum length after fixed pole 3 and the sliding extension of lever 4 should be at least more than the width for being equal to bed board, to guarantee ladder Normal use.

Wherein, sliding slot 7 is again provided on the medial surface of lever 4, rotating bar 5 is slidably connected at by sliding block 9 and lever 4 Together, together with rotating bar 5 is rotatably connected with sliding block 9, herein, the sliding connection structure between sliding block 9 and lever 4 is self-locking Type sliding connection structure, meanwhile, the Rotatable connecting structure between rotating bar 5 and sliding block 9 is also self-locking type, and setting so is It is safer when in order to use, the changes of 5 position and direction of rotating bar may be implemented by sliding and rotating, ladder is put It sets in the side of sleeper bed, facilitates passenger or more.

Wherein, cross bar 6 is fixedly installed between two rotating bars 5, the setting of cross bar 6 should use between sleeping berth two-berth Distance, facilitate passenger or more, be not specifically limited herein, as shown in Figure 2 and Figure 3, when rotating bar 5 slides in and out and to backspin When turning, cross bar 6 follows rotating bar 5 to move downward outward, facilitates passenger or more.

Wherein, it is preferred that be additionally provided with Antiskid fixing device in the bottom end of rotating bar 5, such safety is higher, in cross bar Non-slip mat is additionally provided on 6, the setting of non-slip mat can prevent passenger's foot slips when upper and lower, prevent contingency Occur, security performance is higher.

The utility model when it is implemented, as shown in Figure 2 and Figure 3, whole device is mounted on to the lower section of bed board side, will After lever 4 and rotating bar 5 pull out, rotating bar 5 is rotated down, will be rotated by the fixation anti-skid device of 5 bottom end of rotating bar Bar 5 can be used after fixing, and after use, ladder can be contracted in the lower section of bed board by the inverted repeat above process, It does not take up space and convenient to use, safety is also higher.

The foregoing is merely the better embodiments of the utility model, are not intended to limit the utility model, all in this reality Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the utility model Within protection scope.
