Abstract

The utility model discloses an improved structure of a luggage gemel. The improved structure comprises an upper hinge fitted with an upper box body and a lower hinge fitted with a lower box body, wherein the upper hinge is hinged with the lower hinge; the lower hinge is equipped with a bending part sunken towards the box body at the hinged end; the section of the bending part is shaped like a rectangle with one side unsealed, and fitted with the box body; when the upper hinge is completely open, the position of a rivet hole formed in the upper hinge moves in a space formed by the bending part, so that the upper hinge and the lower hinge do not collide with each other while being completely opened, and therefore, a problem that a conventional gemel is easy to get loose or deform after being used for a certain time is solved, and strength is high.

Description

A kind of improvement structure of luggage hinge

Technical field

The utility model relates to a kind of hinge, in particular for the hinge on case and bag.

Background technology

Hinge is more common a kind of structure in daily life, be widely used on some rotary assemblies, as some doors, window, case and bag etc., the major function of hinge is exactly to connect two assemblies that mutually rotate, the hinge that more conventional hinge is hinge type on the market, can be divided into, lower two hinges, several locating holes are set on hinge, for the fixing assembly rotating, use, but conventional upper and lower two hinges of hinge-type hinge are planar substantially, fixing with assembly is to fix by rivet or screw in locating hole substantially, when assembly (such as case and bag) is opened so completely, go up between hinge and lower jaw when turning to 0 degree and overlap from 180 degree, rivet on upper hinge or screw can touch rivet or the screw on lower jaw, have plenty of and directly touch on lower jaw, laminating type will go wrong like this, first the stress ratio being subject to that is exactly hinge is more concentrated, and stress concentrates on the rivet or screw of fixing use substantially, after long-term touching is even clashed into, easily produce loosening, affect hinge and tight ness rating casing, secondly hinge surface is touched for a long time or is clashed into the areal deformation that easily causes hinge, directly affect the life-span of hinge.

Utility model content

The utility model technical issues that need to address are, a kind of improvement structure of luggage hinge is provided, and when upper and lower hinge is opened completely, do not bump, and have solved the conventional hinge easy problem of loosening or distortion in use for some time, better in intensity.

The technical solution of the utility model is: a kind of improvement structure of luggage hinge, comprise the upper hinge that fits in upper box and the lower jaw that fits in lower box, described upper hinge and lower jaw are hinged, it is characterized in that: lower jaw is provided with towards the bending part of lower box indent at hinged end, the cross section of described bending part is the not rectangle of edge sealing of a side.

Preferably, described upper hinge and lower jaw are aluminum alloy material, by extrusion modling, make, the advantage that aluminium alloys is compared conventional irony is gently, and is not easy to get rusty, and the hinge of general irony is substantially with punching press or flanging manufacturing process, to pass through several procedures, in precision, be not easy control, and by the words of aluminium material, can use the form of aluminium extrusion, by one technique of aluminum extrusion die, just completed, in precision, easily guaranteed.

Preferably, the end of described upper hinge is provided with crotch portion, and upper crotch portion can catch on the upper retainer ring on upper box, makes to coordinate between hinge and upper box tightr, and bears some stress.

Preferably, described lower jaw end is provided with lower crotch portion, and lower crotch portion can catch on the lower retainer ring on lower box, makes to coordinate between lower jaw and lower box tightr, and bears some stress.

Adopt after the technical program, on lower jaw, be provided with one to the bending part of lower box indent, like this after upper hinge Rotate 180 degree, be fixed in the formed space of bending part that rivet on hinge or screw can drop on indent, case and bag are under open mode like this, can there is not mutual collision in upper and lower hinge, the screw that it is fixed in the above or rivet also can not touch the surface of hinge, increased the application life of hinge.

Accompanying drawing explanation

The schematic three dimensional views that accompanying drawing 1 is this hinge;

Accompanying drawing 2 is arranged on the schematic diagram on case and bag for hinge;

Accompanying drawing 3 is the partial side view under case and bag are opened completely.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:

As shown in Figure 1 to Figure 2, hinge in of the present utility model can be divided into hinge 1 and lower jaw 2, both are hinged by middle hinged seat, wherein lower jaw 2 is provided with a bending part 21, as can be known from Fig. 2, this bending part 21 is towards a side indent of lower box 4, and fit with lower box, the cross section of its bending part 21 is the rectangle of an open-ended, bending part and lower box binding face are provided with rivet locating hole, described upper hinge 1 and lower jaw 2 are aluminum alloy material, by being crushed to, the advantage that aluminium alloys is compared conventional irony is gently, and be not easy to get rusty, and the hinge of general irony is substantially with punching press or flanging manufacturing process, to pass through several procedures, in precision, be not easy to control, and can be by the form of aluminium die casting by the words of aluminium material, by one technique of aluminium compression mod, just completed, in precision, easily guarantee, the end of described upper hinge 1 is provided with crotch portion 11, upper crotch portion can catch on the upper retainer ring 31 on upper box 3, retainer ring 31 is more common on case and bag, conventionally retainer ring is metal material, role is to reinforce case and bag, prevent case and bag distortion, and crotch portion 11 on arranging on upper hinge, upper retainer ring 31 these structures have well been utilized, make to fit between hinge and upper box tightr, simultaneously also for the upper rivet 12 on upper hinge has been shared a part of stress, a lower crotch portion 22 is in like manner also set on lower jaw, catch on the lower retainer ring 41 on lower box 4.

Be illustrated in figure 3 the case and bag under full open position, now go up hinge and rotated 180 degree with the upper hinge in Fig. 2, as can be seen from Figure, on upper hinge, for fixing upper rivet 12, dropped in the space of bending part 21 indents formation, not direct and lower jaw 2 is touched, can not touch the lower rivet on lower jaw simultaneously yet, and the stress that the stress that can bear of the lower jaw after bending can bear than the hinge of single plane formula is high, can find out from the side, lower crotch portion on lower jaw has caught on the lower retainer ring 41 on lower box 4, like this, when even lower jaw 2 is subject to the stress drawing to the right, the lower rivet 23 of being not only on lower jaw is born stress, lower crotch portion also can share a part of stress, so just prevent lower rivet 23 easy loosening problem after long-term use, the upper crotch portion of in like manner going up on hinge 1 is also the same operating principle.

Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure allows to change, the face of hinge and casing laminating can change and change according to the side of casing, those skilled in the art can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
