Abstract
The utility model discloses a kind of adjustable folding support, belong to furniture technical field of auxiliary equipment.This device comprises grooved fixed bar, grooved dwang, flute profile oblique fulcrum bar and spring, one end of described grooved fixed bar and described grooved dwang hinge, the middle and lower part of described grooved fixed bar and one end hinge of described flute profile oblique fulcrum bar, other one end of described flute profile oblique fulcrum bar is connected with described flute profile dwang, connected by described spring between described flute profile fixed bar and described flute profile oblique fulcrum bar, described spring forms certain pulling force between described flute profile fixed bar and described flute profile oblique fulcrum bar.This device can be completely folding when folding, substantially reduces this device occupying the useful space; And upon deployment, suitable angle can be selected again to widen plane, regioselective is many, and this device can bear larger load.
Description
Technical field
The utility model belongs to furniture technical field of auxiliary equipment, is specifically related to a kind of adjustable folding support.
Background technology
In existing furniture, when widening the plane of furniture, how folding rack can be adopted.But existing folding rack location is single, and structure stress is less.Simultaneously when not using, common folding rack can not be completely folding, greatly occupies the useful space of furniture.
Utility model content
The purpose of this utility model is for above-mentioned deficiency, proposes the adjustable folding support that a kind of structure stress is larger.
The technical solution adopted in the utility model is:
A kind of adjustable folding support, comprise grooved fixed bar, grooved dwang, flute profile oblique fulcrum bar and spring, one end of described grooved fixed bar and described grooved dwang hinge, the middle and lower part of described grooved fixed bar and one end hinge of described flute profile oblique fulcrum bar, other one end of described flute profile oblique fulcrum bar is connected with described flute profile dwang, connected by described spring between described flute profile fixed bar and described flute profile oblique fulcrum bar, described spring forms certain pulling force between described flute profile fixed bar and described flute profile oblique fulcrum bar.
Further, one end of described grooved fixed bar is by the first bearing pin and described grooved dwang hinge.
Further, one end hinge of the second bearing pin and described flute profile oblique fulcrum bar is passed through in the middle and lower part of described grooved fixed bar.
Further, other one end of described flute profile oblique fulcrum bar is connected with described flute profile dwang by positioning tooth.
Further, described positioning tooth is opened on described flute profile dwang.
Further, described flute profile fixed bar and described flute profile oblique fulcrum bar are provided with punching press hook, and described spring is fixed on described punching press hook.
Further, described flute profile dwang has screw hole.
Preferably, the quantity of described screw hole is at least one.
The beneficial effects of the utility model are:
This apparatus structure is simple, and production cost is low; This device can be completely folding when folding, substantially reduces this device occupying the useful space; And upon deployment, suitable angle can be selected again to widen plane, regioselective is many, and this device can bear larger load.
Accompanying drawing explanation
Structural representation during a kind of adjustable folding support expansion that Fig. 1 provides for the utility model embodiment;
Structural representation during a kind of adjustable folding support-folding that Fig. 2 provides for the utility model embodiment.
In figure: 1, flute profile fixed bar, 2, flute profile oblique fulcrum bar, 3, flute profile dwang, 4, spring, 1-1, the first bearing pin, 1-2, the second bearing pin, 3-1, screw hole, 3-2, positioning tooth.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
See figures.1.and.2, present embodiments provide a kind of adjustable folding support, comprise grooved fixed bar 1, grooved dwang 3, flute profile oblique fulcrum bar 2 and spring 4.One end of grooved fixed bar 1 is by the first bearing pin 1-1 and grooved dwang 3 hinge.One end hinge of the second bearing pin 1-2 and flute profile oblique fulcrum bar 2 is passed through in the middle and lower part of grooved fixed bar 1.Other one end of flute profile oblique fulcrum bar 2 is connected with flute profile dwang 3 by positioning tooth 3-2.Connected by spring 4 between flute profile fixed bar 1 and flute profile oblique fulcrum bar 2, flute profile fixed bar 1 and flute profile oblique fulcrum bar 2 are provided with punching press hook, and spring 4 is fixed on punching press hook.Spring 4 forms certain pulling force between flute profile fixed bar 1 and flute profile oblique fulcrum bar 2.Because grooved fixed bar 1, grooved dwang 3 and flute profile oblique fulcrum bar 2 all adopt bathtub construction, the cooperation clamped mutually again each other, so whole device is better stressed, can bears larger power and keep stable.Flute profile dwang 3 has three screw hole 3-1.
When using this device, with reference to Fig. 1, only need mention flute profile dwang 3 to corresponding angle position, also allow flute profile oblique fulcrum bar 2 rotate simultaneously, the free end brank of flute profile oblique fulcrum bar 2 is made to enter on the corresponding positioning tooth position 3-2 of flute profile dwang 3, then flute profile fixed bar 1 is fixed by screws in and will widens corresponding position, finally the panel that will widen is fixed on flute profile dwang 1 by the screw hole 3-1 of screw above flute profile dwang 1, such panel just serves the effect of widening, and can bear very large load simultaneously.When need of work does not fold this device, with reference to Fig. 2, mention flute profile dwang 3 a little, firmly flute profile oblique fulcrum bar 2 is down rotated, put down flute profile dwang 3 simultaneously, thus make all channel-shaped bar be folded into one.
This apparatus structure is simple, and production cost is low; This device can be completely folding when folding, substantially reduces this device occupying the useful space; And upon deployment, suitable angle can be selected again to widen plane, regioselective is many, and this device can bear larger load.
It should be noted last that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
