Embodiment

Below in conjunction with accompanying drawing, specify the utility model.

Core of the present utility model is: the barb that comes off is put in the inwall setting in the support arm both sides, make hinge with the bed inside casing firm and reliable connection.

See also Fig. 1, it is the decomposing schematic representation of the adjustable bed turning joint hinge of the utility model, and this adjustable bed turning joint hinge has comprised structure identical hinge 1 and hinge 5, Pivoting bearing 2, hinge rotating shaft latch 3 and latch buckle 4.

Shown in Fig. 2 A-Fig. 2 C, hinge 1 structure that is formed in one, it comprises circular articulated section 11 and support arm 12, in the circular articulated section 11 one first groove 111 is set, first groove, 111 inwalls are provided with circular first projection 112, projection 112 endoporus are set to hollow, form in order to insert the latch patchhole 113 of hinge rotating shaft latch 3.Support arm 12 both sides inwalls are provided with Drop-proof barb 122, and support arm 12 both sides also are provided with two corresponding circular holes 121 in order to connecting screw.

In this example, barb 122 is arranged to one to protruding gradually slope, support arm inside, the slope end is arranged to semicircle, the joint of bed inside casing is provided with and the corresponding shrinkage pool of barb 122 shapes, after being inserted in bed inside casing joint in the support arm, barb 122 and the mutual clamping of shrinkage pool make the firm and reliable connection of hinge and bed inside casing.

In this example, need to prove, barb 122 is arranged to semicircle slope shape, limit shape therewith but have more than, in actual use, the shape of specific design barb 122 as required, therefore, above-mentioned barb 122 is arranged to semicircle slope shape is an example, and is not used in qualification the utility model.
