Abstract

The utility model relates to a hinge with one pin for an aluminium box, which is composed of two hinges with identical structure and size and a shaft bolt, wherein, the surfaces of the hinges are provided with punch holes and are respectively riveted with a box cover and a box case of an aluminium box, and the punch holes are provided with rivets; one end of each hinge is at least extended with two bolt pipes at intervals, and the center of each bolt pipe is provided with a bolt hole used for the bolt connection of the same shaft bolt. The utility model is characterized in that one end of the surface of each hinge is provided with a cross rib along the connecting point of the bolt pipes. The utility model ensures that the connecting intensity of the box cover and the box case is enhanced, and the installation is convenient.

Description

The hinge with one pin of aluminium case

The utility model relates to the aluminium case, relates in particular to the chamber of aluminium case and the hookup of case lid.

The back button hookup of existing aluminium case, as Figure 1-3: back button 1 comprises two identical hinge 2 and bolts 3 thereof, hinge 2 surfaces wear 21, for establishing rivet 43, what hinge 2 one ends were interval with into tubulose colludes sheet 22, collude sheet 22 tail ends towards axially protruding out a tab 23, mat axle 3 passes and colludes the case lid 41 and chamber 42 that sheet 22 composition back button 1, two hinges 2 are divided into aluminium case 4.This back button 1 has following shortcoming: one is two hinges 2 axially establishes tab 23 and leans with the sheet 22 that colludes of tubulose, and when aluminium case 4 was opened, its angle easily card ended, and intensity is relatively poor, tab 23 yielding fractures; Even overturning backward; The 2nd, sheet 22 processing of colluding of tubulose bother; Three is flangings 44 that the edge of two hinges 2 is loaded on case lid 41, chamber 42 respectively, and flanging 44 must alignment, but does not have locating structure, installs both inconvenient, accurately difficult again.

The purpose of this utility model provide a kind of intensity better, the hinge with one pin of the aluminium case being convenient to install.

The purpose of this utility model is achieved in that the hinge with one pin of aluminium case, it is made of two structures and the identical bolt of hinge mat of size, hinge surface is provided with perforation and wears rivet, rivet mutually with the case lid and the chamber of aluminium case respectively, hinge one end is stretched at least at interval and is provided with two bolt pipes, the logical keyhole that is provided with for the same axle of bolt bolt of bolt tube hub; It is characterized in that: this hinge surface one end hangs down along bolt pipe junction and establishes a cross rib.

Above-mentioned design when two hinges rotate mutually with its bolt, can lean and blocks the angle that only is predetermined according to cross rib, reaches the effect that intensity is good, be convenient to install.

Below by drawings and Examples the utility model is described further again.

Shown in Fig. 4-7: the utility model is made of two structures and the identical bolt 7 of hinge 6 mats of size, hinge 6 surfaces are provided with perforation 61 and wear rivet 43, rivet mutually with the case lid 41 and the chamber 42 of aluminium case 4 respectively, hinge 6 one ends are stretched at least at interval and are provided with two bolt pipes 62, the logical keyhole 63 that is provided with for the same axle of bolt bolt 7 in bolt pipe 62 centers; It is characterized in that: these hinge 6 surperficial ends hang down along bolt pipe junction and establish a cross rib 64.Wherein, hinge 6 outer rims are folded into flap 65 towards the back side, and flap 65 can collude the flanging 44 of being located at case lid 41 chambers 42.The back button 5 that the utility model is formed, its hinge limit 6 forms for the punching out of whole piece aluminium extruded type one, the setting of flap 65 both had been convenient to install, can be not crooked, guaranteed the accurate of installation, the intensity of back button 5 is increased, and the setting of cross rib 64 had both guaranteed default opening angle, further improved the intensity of back button again, and the efficient of installation is improved, and cost reduces relatively.

Claims (2)

1, the hinge with one pin of aluminium case, it is made of two structures and the identical bolt of hinge mat of size, hinge surface is provided with perforation and wears rivet, rivet mutually with the case lid and the chamber of aluminium case respectively, hinge one end is stretched at least at interval and is provided with two bolt pipes, the logical keyhole that is provided with for the same axle of bolt bolt of bolt tube hub; It is characterized in that: this hinge surface one end hangs down along bolt pipe junction and establishes a cross rib.

2, the hinge with one pin of aluminium case as claimed in claim 1 is characterized in that: wherein, the hinge outer rim is folded into flap towards the back side, and flap can collude the flanging of being located at the case lid chamber.
