Abstract

The invention discloses a back-to-back folded hollow shaft hinge. The back-to-back folded hollow shaft hinge comprises a primary chain body with a cylindrical sleeve body at one and a secondary chain body with an upper circular flat sleeve opening and a lower circular flat sleeve opening at one end, which are connected in series to form a whole body through a hollow shaft. The back-to-back folded hollow shaft hinge can be used for assembling two components which are made of a sheet material and are required to be folded on an identical plane, and particularly, can be matched with solid shaft hinges of the same type to produce a plurality of novel assemblies, thus increasing the product types and optimizing the life of humans.

Description

The back-to-back hollow shaft hinge of amounting to

Technical field:

The present invention relates to a kind of discrete, especially a kind of back-to-back hollow shaft hinge of amounting to.

Background technique:

The hinge of continuing to use at present can only be applied to the larger member of assembled position area, and the assembling of and two members need at grade amounting to little to thickness is just helpless.

Summary of the invention:

For satisfying people in the pro forma more demands of object assembling, the invention provides a kind of back-to-back hollow shaft hinge of amounting to, the public serobila that it is characterized in that forming hinge is the channel-section steel formula member that a headband has the drum type body, the fundamental chain body is one and is provided with the up and down channel steel shape member of two circular flat sleeve-board mouths, two circular flat sleeve-board mouths of fundamental chain body the upper and lower opening of the drum type body that is arranged at public serobila left rear side and with the hollow shaft string altogether in the right lateral side clamping of fundamental chain body, and two of hollow shaft is concordant with the two ends of the engaging body that is closed by string.

The present invention implements with the following method: 1, select the long-pending iron sheet of suitable thickness and plane by the specification requirement of made hinge, be cut into " protruding " font, it is that 90 ° of angles become channel steel shape that the iron plate of " protruding " font body both wings is rolled over toward same direction, dorsal part with the past cell body of " protruding " font body head is curled into the drum type body again, and this is public serobila; 2, cut " only " font iron sheet by above-mentioned materials scheme, the two point form of " only " font body partly is two circular flat boards that are connected on " mouth " font body, make a call to a front states the circular hole that the intracavity diameter of drum type body equates and becomes circular flat sleeve-board mouth at circular dull and stereotyped position, the center of circle, simultaneously two circular flat sleeve-board mouths are rolled over backward 90 ° and the left and right sides both wings of " mouth " font body iron sheet are rolled over forward 90 ° become channel steel shape, this is the fundamental chain body; 3, two circular flat sleeve-board mouths of fundamental chain body are clamped two mouthfuls up and down of drum type body of public serobila, close with a hollow shaft string, two of hollow shaft is concordant with the two ends of the engaging body that is closed by string.Purposes of the present invention is, the combination that two members of making of thin plate class material can be carried out both are amounted at grade mutually from the section of thin plate, especially can cooperate with other hollow shaft hinge of same class, can greatly enrich the combining form of member, diversify, optimize human life.

Description of drawings:

Fig. 1 is it " protruding " font iron sheet of public chain body and function; Fig. 2 is public serobila design sketch; Fig. 3 is it " only " font iron sheet of fundamental chain body and function; Fig. 4 is fundamental chain body design sketch; Fig. 5 is design sketch of the present invention; Fig. 6 is the hollow shaft design sketch.Among the figure, the 1st, public serobila cell body wallboard, the 2nd, " protruding " font body head, the 3rd, public serobila cell body folding lines, the 4th, drum type body, the 5th, fundamental chain body cell body wallboard, the 6th, circular flat sleeve-board mouth, the 7th, fundamental chain body cell body folding lines, the 8th, hollow shaft.

Embodiment:

As shown in Figure 5, circular flat sleeve-board mouth (6) on the fundamental chain body shown in Figure 4 is held on the upper and lower opening place of the drum type body (4) on the public serobila shown in Figure 2, therefrom go here and there with hollow shaft (8) and to close, make two of axle core concordant with circular flat sleeve-board mouth; The notch of male and female serobila is towards the same side.During application, the respective cross-section of thin-plate element inserted in the corresponding serobila groove clamp.

Claims

1. back-to-back hollow shaft hinge of amounting to, the public serobila that it is characterized in that forming hinge is the channel-section steel formula member that a headband has the drum type body, the fundamental chain body is one and is provided with the up and down channel steel shape member of two circular flat sleeve-board mouths, two circular flat sleeve-board mouths of fundamental chain body the upper and lower opening of the drum type body that is arranged at public serobila left rear side and with the hollow shaft string altogether in the right lateral side clamping of fundamental chain body, and two of hollow shaft is concordant with the two ends of the engaging body that is closed by string.
