Abstract

A bed extending device is characterized in that the device comprises a bedside lower part [1] and a bedside upper part [2]. The lower end of the bedside upper part [2] is pivotally connected to the upper end of the bedside lower part [1] with a rotation shaft [5] which is arranged on the bedside upper part, and the bedside lower part [1] is pivotally connected to one end of a support bar [4] with a support rotation shaft [7], then the support bar [4] crosses a guiding space [6] which is arranged on the bedside upper part [2] and is provided with at least one locking device [8]. When the bedside is in the extending condition, the end of the support bar [4] is propped up by the locking device [8].

Description

The Lengthening mechanism of bed

Technical field

The utility model relates to a kind of bed, the particularly Lengthening mechanism of Children.

Background technology

In the prior art, particularly Children is because child growth is very fast, original body length is just not enough, this just needs the lengthened bed body, often adopt at present and set level the method that extends after the first half head of a bed of a side taken off, this structure since when lengthening the head of a bed be separated with a bed body, therefore operation is very inconvenient.

Summary of the invention

The purpose of this utility model is to provide a kind of Lengthening mechanism of easy to operate bed.

The technical solution of the utility model is: a kind of Lengthening mechanism, it comprises head of a bed bottom, head of a bed top, the bottom on described head of a bed top is connected by head of a bed top rotating shaft phase pivot with the upper end of head of a bed bottom, on the described head of a bed bottom by the pivotally connected end that support bar is arranged of support member rotating shaft, this support bar passes the guide space that is provided with on the described head of a bed top, at least be provided with a limiting section in this guide space, be at the head of a bed and add under the long status, the end of described support bar withstands on the described limiting section.

The utility model compared with prior art has following advantage:

Head of a bed top and bed subordinate portion are always and pivot together, and therefore only need lift or put down head of a bed top can realize holding up or setting level of the head of a bed, simple to operate.

Description of drawings

Accompanying drawing 1 is the structural front view of the utility model before not having lengthening;

Accompanying drawing 2 is the structure left view of the utility model before not having lengthening;

Accompanying drawing 3 is the structure left view of the utility model behind lengthening; Wherein:

Wherein: [1], head of a bed bottom; [2], head of a bed top; [3], locating part; [4], support bar; [5], head of a bed top rotating shaft; [6], guide space; [7], support member rotating shaft; [8], limiting section;

The specific embodiment

Referring to accompanying drawing 1 to accompanying drawing 3, a kind of Lengthening mechanism, it comprises head of a bed bottom [1], head of a bed top [2], the bottom on described head of a bed top [2] is connected by head of a bed top rotating shaft [5] phase pivot with the upper end of head of a bed bottom [1], go up by the pivotally connected end that support bar [4] is arranged of support member rotating shaft [7] described head of a bed bottom [1], this support bar [4] passes described head of a bed top [2] and goes up the guide space [6] that is provided with, at least be provided with a limiting section [8] in this guide space [6], be at the head of a bed and add under the long status, the end of described support bar [4] withstands on the described limiting section [8], described support bar [4] is the U-shaped structure, the bottom of its opening is connected with head of a bed bottom [1] phase pivot, the rod member of its upper lateral partly withstands on the limiting section [8], this moment, head of a bed top [2] horizontal positioned was common as the bed behind the lengthening with bed board.

Be fixed with locating part [3] on the described head of a bed top [2], constitute described guide space [6] between the outside of the medial surface of described locating part [3] and head of a bed top [2], described limiting section [8] is positioned at the upper end of locating part [3] and the fixed connection place of head of a bed top [2].

Claims

1, a kind of Lengthening mechanism, it is characterized in that: it comprises head of a bed bottom [1], head of a bed top [2], the bottom on described head of a bed top [2] is connected by head of a bed top rotating shaft [5] phase pivot with the upper end of head of a bed bottom [1], go up by the pivotally connected end that support bar [4] is arranged of support member rotating shaft [7] described head of a bed bottom [1], this support bar [4] passes described head of a bed top [2] and goes up the guide space [6] that is provided with, at least be provided with a limiting section [8] in this guide space [6], be at the head of a bed and add under the long status, the end of described support bar [4] withstands on the described limiting section [8].

2, the Lengthening mechanism of bed according to claim 1, it is characterized in that: be fixed with locating part [3] on the described head of a bed top [2], constitute described guide space [6] between the outside of the medial surface of described locating part [3] and head of a bed top [2], described limiting section [8] is positioned at the upper end of locating part [3] and the fixed connection place of head of a bed top [2].
