Description

Adjustable bed turning joint hinge

Technical field

The utility model relates to a kind of joint hinge, relates in particular to a kind of adjustable bed turning joint hinge that connects adjustable bed bed inside casing.

Background technique

Along with the raising of development of technology and people's living standard, pulldown bed, manually bed, liked by people from movable bed, beddo etc. are adjustable bed.An adjustable bed housing and the bed inside casing of comprising, the bed housing is used to support the whole bed body, and the bed inside casing is divided into some joints, flexibly connects between each joint, to realize lifting function.Flexible connection in the prior art between adjustable bed each joint of bed inside casing adopts iron plate to connect more.

Adopting the iron plate ways of connecting is the joint that is locked at an inside casing one joint with the end that screw is provided with two ends the iron plate of screw hole, the other end is locked at the joint of another joint of joint connection therewith, connect by iron plate between two joints, and, by the space between iron plate and screw, the joint can be movable flexibly, realizes adjustable bed lifting function.This kind Placement only needs an iron plate can realize being connected with some screws, and is with low cost.But, because iron plate is hard sharp, is easy to the scratch human body or scratches article, make troubles for people's use, and it is not attractive in appearance that this kind connects the utmost point.

It is that each jointing cover that saves of bed inside casing is connected to the support arm connecting end that is movably hinged the joint that employing is movably hinged the joint ways of connecting, realizes lifting function by being movably hinged the joint.Being movably hinged the joint in the prior art is being fastened and connected together by two articulated elementss, as State Patent Office's application number is 03223743.X, name is called a kind of patent application that is movably hinged the joint, this is movably hinged the joint and is made of two articulated elementss fastening, articulated elements one end is a circular articulated section, one end is the support arm connecting end, have another circular articulated section of tubular circular hole in the one circular articulated section and be provided with circular convex cylindrical body, cylindrical body and tubular shrinkage pool fasten and adapt, be provided with an annular groove at tubular shrinkage pool inwall, the cylindrical body corresponding position has the hole, is provided with spring and locating piece in the hole, and locating piece buckles into annular groove just.This articulated elements is fastened and connected by pore and Cylindrical object, snaps together between the articulated elements, and buckles in the annular groove by locating piece and to locate, between the articulated elements in conjunction with compact, gap, beautiful shape can not appear between the articulated elements, it is flexible that this is movably hinged joint motion simultaneously, durable in use.

But this is movably hinged the joint and the circular articulated section of two articulated elementss need be made into respectively in the circular articulated section and has tubular circular hole, another circular articulated section is provided with circular convex cylindrical body, and this cylindrical body can fasten mutually with this tubular shrinkage pool, this just causes this to be movably hinged the fabricating cost height in joint, and, because two articulated elementss use in pairs, in case a damage in two articulated elementss, then another is also just scrapped, and causes the waste of resource.

In sum, exist in Placement of each joint of the adjustable bed bed of prior art inside casing use inconvenient, aesthetic property is poor, the technical problem of cost height, serious waste of resources.

For achieving the above object, the utility model provides a kind of adjustable bed turning joint hinge, comprising: two hinge, Pivoting bearing, hinge rotating shaft latch and latch buckles that structure is identical.Hinge comprises circular articulated section and support arm, in the circular articulated section one first groove is set, the first groove inwall is provided with circular first projection, and the first protruding endoporus is set to hollow, formation is in order to insert the latch patchhole of hinge rotating shaft latch, and circular articulated section and support arm are one-body molded.Pivoting bearing is socketed in first groove of two hinges, and hinge rotating shaft pin bushing is connected in the patchhole of two hinges, latch buckle and the clamping of hinge rotating shaft latch.

According to the described adjustable bed turning joint hinge of the utility model preferred embodiment, its support arm both sides inwall is provided with the Drop-proof barb.

According to the described adjustable bed turning joint hinge of the utility model preferred embodiment, its support arm both sides are provided with two corresponding circular holes in order to connecting screw.

According to the described adjustable bed turning joint hinge of the utility model preferred embodiment, its Pivoting bearing is a hollow cylinder, and the cylindrical body endoporus is provided with a circle second projection.

According to the described adjustable bed turning joint hinge of the utility model preferred embodiment, its latch buckle comprises a buckle head and an axial region that is connected with the buckle head, and axial region inside is hollow shape, and arranged outside has a circle the 3rd projection.

According to the described adjustable bed turning joint hinge of the utility model preferred embodiment, its hinge rotating shaft latch comprises that a latch head and an end are arranged on the latch head and the discerptible leg of the other end.Form in the middle of the leg in order to insert the buckle patchhole of latch buckle axial region, the leg inboard is provided with and the second corresponding groove of latch buckle axial region the 3rd projection.

According to the described adjustable bed turning joint hinge of the utility model preferred embodiment, its latch head is arranged to hollow shape.

When the adjustable bed turning joint hinge of the utility model uses bed inside casing joints sleeve is inserted in the support arm, with screw hinge is locked on the inside casing again and gets final product, this adjustable bed turning joint hinge beautiful shape, easy to use.Compared with prior art, the utlity model has following advantage:

1, two of this adjustable bed turning joint hinge hinges adopt identical structure, and fabricating cost is cheap, and when one of them hinge damages, the hinge that only needs to damage is changed, original another hinge still can continue to use, and maintenance cost is low, has saved resource.

2, the hinge support arm inboard of this adjustable bed turning joint hinge is provided with and puts the barb that comes off, and makes hinge more solid and reliable with being connected of bed inside casing.

3, the latch head of this adjustable bed turning joint hinge is arranged to hollowly, communicates with the leg patchhole, with in the screw-driver patchhole, firmly the latch buckle is outwards ejected and the latch buckle can be unloaded again during dismounting, is easy to dismounting.
