Abstract

The utility model relates to a novel foldable platform hinge, which is improved based on the traditional foldable platform hinge. The foldable platform hinge comprises an internal casing, an external casing and a rotary axle; wherein, the end of the internal casing is provided with a chucking position for supplying vacant position, and the external casing is fixed with a spring sheet. The internal and the external casings rotate for an angle from 0 degree to 180 degrees through the rotary axle. When the platform hinge is opened, three rotary axles are not in the same line. In addition, with the support of the coach spring, the platform hinge is fixedly propped and cannot be automatically closed up, and then a fixed angle of 90 degrees is formed by the platform rack and the platform foot, to ensure the stability of the supporting top of the platform foot. Meanwhile, a small space is occupied when the hinge platform is folded up, which facilitates the transportation of the foldable platform. The utility model is easy to open and close, and has clear and fine sound, firm structure, and high reliability and practicability.

Description

Folding table-hinge

Technical field

The utility model relates to a kind of white hinge that is used to connect stone face pallet pin, and particularly a kind of can opening gently and folding Folding table-hinge belongs to the furniture for public premises articles for use.

Background technology

Because the raising of people's living standard and need local a large amount of various and folding platforms that use such as hotel, student building and function assembly hall, classroom.Folding platform can be furnished flexibly, receives and folds, and can give full play to the function in hall, and therefore, folding platform is extensive use of.Though but the Folding table-hinge that present popular on the market folding platform is used has folder function, its weak point is when folding, cylindrical screw shape golden hair in the table-hinges goes out strange sound, very ear-piercing, and lift down easily even, dangerous, because the platform pin supports injustice, run into whole platform of platform pin because of carelessness and will topple over.Moreover the folding back of this old-fashioned back flap hinge degree is thicker, is unfavorable for folding transportation.

Summary of the invention

The utility model is designed the Folding table-hinge that a kind of new type foldable is used, and sound construction is clear during the table-hinges folding, melodious, the folded segment save space, thus reach easy to use, reliable, the purpose that secure voice is little.

The utility model is made up of inner casing, shell and axis of rotation, in the enclosure with the rivet spring leaf of riveting over, be provided with screens at the inner casing head end, all have the circular hole that runs through that connects use for axis of rotation at head, the tail two ends of inner casing, shell, axis of rotation is coupled together inside and outside shell by the circular hole that passes inside and outside shell head, constitutes the main body of Folding table-hinge.The circular hole of inside and outside shell tail end connects by axis of rotation goes up the table-hinges sign indicating number, and the table-hinges sign indicating number is connected with the platform pin with the table top frame respectively again, so just constitutes operational folding platform.When Folding table-hinge was opened, three axis of rotation axial lines were on same plane.

The utility model is like this work: at the inwall of the shell spring leaf of riveting over, inner casing is enclosed within the shell, the head end of inside and outside shell connects with axis of rotation, and tail end is connected with the table-hinges sign indicating number with axis of rotation.During use, the table-hinges sign indicating number of tail end is separately fixed on table top frame and the platform pin, when table-hinges was opened, inside and outside shell rotated in line (180 °) around axis of rotation, thus fixed mesa and platform pin; When superimposed, inside and outside, shell rotates in line (0 ° of angle) around axis of rotation.

This table-hinges modern design, rational in infrastructure, firmly, and safety, the platform pin can not tilt, and clear during folding, volume is little, and saves 40% space than traditional folding platform when folding, is convenient to transportation.

Among the figure, 1-1. table-hinges sign indicating number, 1-2. table-hinges sign indicating number, 2-1. axis of rotation, 2-2. axis of rotation, 2-3. axis of rotation, 3. inner casing, 4. shell, 5. spring leaf, 6. rivet, 7. screens.

The specific embodiment

In Fig. 1, axis of rotation 2-1 passes the circular hole of inner casing 3 and shell 4 cephalic pars, inside and outside shell is coupled together, thus the main body of formation Folding table-hinge, and make inside and outside shell do 0 °～180 ° rotations along axis of rotation; The circular hole that axis of rotation 2-2 passes inner casing 3 afterbodys is connected shell with table-hinges sign indicating number 1-1, the circular hole that axis of rotation 2-3 passes shell 4 afterbodys is connected shell with table-hinges sign indicating number 1-2, and the table-hinges sign indicating number that couples together with inside and outside shell is separately fixed on table top frame and the platform pin again.In shell 4 with rivet 6 spring leaf 5 of riveting over, have the rectangle breach of ammunition feed elasticity of spring leaf deformation activity at the cephalic par of shell 4, spring leaf 5 one ends are fixed on the afterbody of shell 4, and the other end extends the head position that has breach in the shell 4, are provided with screens 7 at the cephalic par of inner casing 3, spring leaf is by the effect of screens, the inside and outside shell of support fixation position, when table-hinges was opened, the top of spring leaf 5 was blocked in screens 7, under the effect of elastic force, does not move the inside and outside shell location.When back flap hinge is opened, three axis of rotation axial lines are not at grade, the vertical join line that is axis of rotation 2-1,2-2 and three axis of rotation axial lines of 2-3 mid point is not on same straight line, and table-hinges is being supported securely can not be closed automatically, thus 90 ° of angles that make stand and platform pin become to fix.
