Description

A kind of folding bed

Technical field

The utility model relates to bedstead, relates in particular a kind of folding bed.

Background technology

But folding bed becomes small size to be convenient to collection because of its folding and transportation is favored by a lot of consumers deeply, and the while is along with the raising of people's living standard, also not only be only limited to soft comfortable in the sleep for the requirement of bed, also need some movable functions, when for example seeing in bed TV, reading or sick rest, all need certain angle is raised at back or knee, partly lie or partly to sit back and wait comfortable posture realizing, perhaps for some special roles the bed, such as the bedstead in the ward or some Bed with special provision for nursing etc.But, general electric driving bed structure is just being set up motor below the bed board of fixed bed frame, make the driven by motor head of a bed or tailstock plate oscilaltion campaign realize the angular adjustment of bedstead, bed frame structure in such bedstead is fixed, structure is also comparatively complicated, and can't folding, carrying gets up to waste time and energy.And most folding bed has just comprised not having backboard by the foldable bedstead that articulates hack lever and form, and can't take to crouch using and lean on.But so how to make bedstead when having the folding function, have again the back bracket that can regulate according to user demand, be problem to be solved in the utility model.

The utility model content

The purpose of this utility model is to provide a kind of folding bed, and this can carry out being provided with movable back bracket in the folding bedstead of folding, and back bracket can support or receive according to user demand and lean against in the bedstead.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of folding bed, include at least two group unit bedstead groups, two adjacent unit bedstead groups are articulated in respectively on the Connection Block at middle part, each unit bedstead group comprises up and down two frame set, include cross bar and vertical pole in each frame set, up and down two cross bars in the frame set are articulated in respectively on the Connection Block up and down, be articulated with at least one group between the upper sheer pole of each unit bedstead group as the connector that supports, wherein be connected with a back bracket in the upper frame group of the unit bedstead group of a side, be connected with one group of connecting rod that supports back bracket between upper frame group and the back bracket.

Described back bracket include respectively with frame set in cross bar cross support arm and the longitudinal girt parallel with vertical pole, the front end of cross support arm is articulated on the medial surface of cross bar, the rear end is resisted against on the support chip that is arranged at the cross bar below.

The two ends of described connecting rod are connected between the cross bar of the cross support arm of back bracket and frame set.

Described connecting rod is to have the telescoping rod that electricity drives elevating mechanism.

After adopting said structure, when bedstead carries out folding, two unit bedstead groups realize receiving by the Connection Block that is articulated in the middle part, upper frame group in each unit bedstead group and underframe group also cooperate simultaneously carries out folding, back bracket is received and is leaned against in the upper frame group, as the part of bedstead, supports in use tiltedly vertical as backrest, do not affect the whole folding of bedstead during folding, thereby Foldable bedstead has the function that can crouch and lean on.

The specific embodiment

In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.

To shown in Figure 5, each unit bedstead group 1, two unit bedstead group 1 was articulated in respectively the Connection Block 2 at middle part about a kind of folding bed that the utility model discloses comprised such as Fig. 1.

Wherein, unit bedstead group 1 comprises respectively upper frame group 11 and underframe group 12, upper frame group 11 includes two and is articulated in the cross bar 111 of Connection Block 2 and the vertical pole 112 between two cross bars and forms frame set, and many vertical poles 112 are in order to the mattress that strengthens 11 pairs of bedsteads tops of upper frame group or the support degree of bed board.Two cross bars 121 of underframe group 12 also are articulated in respectively on the Connection Block 2, so Connection Block 2 is provided with 4 pivot holes to connect cross bar 111 and cross bar 121.

In the same unit bedstead group 1, be articulated with at least one group of connector 3 as supported rod erecting between the cross bar 111 of frame set and the cross bar 121 up and down, in order to support upper frame group 11, in the present embodiment, be articulated with two groups of connectors 3 between upper frame group 11 in unit bedstead group 1 and the underframe group 12, this connector 3 is connected to up and down end and the center of frame set, to realize the support and connection to the bed framework.

In the utility model for making the backed function of folding bedstead tool, be connected with a back bracket 4 in the upper frame group of the unit bedstead group of a side therein, these back bracket 4 activities are articulated in the upper frame group 11 of a unit bedstead group 1 wherein, back bracket 4 includes cross support arm 41 and the longitudinal girt 42 between two cross support arms 41 and forms a frame structure, this cross support arm 41 is parallel with cross bar 111, and longitudinal girt 42 is parallel with vertical pole 112, in upper frame group 11, the front end of cross support arm 41 is to be articulated in one to be arranged on cross bar 111 medial surfaces, and be an end that is positioned near Connection Block 2, it also can be articulated on the cross bar by being articulated on the pin-joint piece, and the rear end of cross support arm 111 is resisted against after being connected on the support chip 13 that is arranged at below the cross bar 111 intersecting with vertical pole 112, thereby back bracket 4 can be supported and fixed in the upper frame group 11, be formed on simultaneously in the upper frame group 11 as supporting rod, as the part of unit bedstead group.Form the support with angle of inclination for making back bracket 4 can tiltedly stand support, between cross bar 111 and cross support arm 41, be articulated with the connecting rod 5 of a support back bracket 4, this connecting rod 5 can be has the telescoping rod that electricity drives elevating mechanism, lower realization is risen or decline controlling, thereby cross support arm 41 is lifted, make back bracket 4 supports erect and form the frame that leans on that carrying out that tiltedly stands crouches and lean on, when not needing back bracket 4, only need connecting rod 5 retractions, back bracket 4 declines are put as in the upper frame group 11, become the bedstead of burnishing surface.

Extremely shown in Figure 5 in conjunction with Fig. 1, when bedstead carries out folding, two unit bedstead groups 1 realize receiving by the Connection Block 2 that is articulated in the middle part, in the folding process, upper frame group 11 in each unit bedstead group and underframe group 12 also cooperate simultaneously carries out folding, and back bracket 4 receipts lean against in the upper frame group 11, as the part of bedstead, support tiltedly in use and stand as backrest, do not affect the whole folding of bedstead during folding.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
