Description

The wardrobe hinge

The utility model relates to a kind of wardrobe hinge, belongs to the theory of mechanisms technical field, is used for wardrobe furniture industry mounting cover formula cabinet door.

The prosperity of furniture industry and adnornment industry grows with each passing day to the requirement of wardrobe hinge.The plain edition hinge is venerated can be used for inserted door and window and wardrobe door, can not be used for lid formula cabinet door in the ascendant, so the pipe type hinge can be applicable to that because of it covering formula cabinet door is used widely, and year surplus in the of leading at home and abroad 20.But this hinge also has many shortcomings:

1, structure and manufacturing are complicated, materials are more, and its cost is higher, is about ten times of general expression hinge;

2, its " tobacco pipe " part must be inlaid in the plate of cabinet door, need grooving on the cabinet door, and cause operation that inconvenience is installed;

3, big (35mm * 22mm), greatly weakened cabinet door intensity of this groove dark (12mm);

4, the disadvantage of tobacco pipe hinge is very easily to damage, and what have has just damaged when mounted, and its reason is that structural concept is not proper, is exemplified below:

(1) the clamp-screw stress condition on the cabinet inner support is abominable---and Dan Ding is subjected to short arm lever power, and this power is about 5～10 times of actual external force; For adjusting position, again should not be with this screw-driving, so when open and close cabinet door, bear higher impact force more fragile coupled part unavoidably;

(2) two design of part complexity being connected with the cabinet door of tobacco pipe hinge and cabinet wall, inconvenience is adopted the steel sheet punch forming and is adopted cast aluminium to be shaped more, and cast aluminium intensity is lower, adds that this place's stress condition is abominable, so this part often damages, is the deadly defect of tobacco pipe hinge;

(3) the tobacco pipe hinge has low the paying that two place's hinge parts all contact with thickness of slab section formation face with Xiao's axle, not only easy to wear but also easily jackknifing, the comprehensive strength that its comprehensive strength contacts with Xiao's axis hole far below plain edition hinge Xiao axle, this also is the long-lived robust basic reason of the latter.

The purpose of this utility model: the above-mentioned four big shortcomings that overcome the tobacco pipe hinge, that design is suitable for, simple in structure, easy system, (be about tobacco pipe hinge cost 1/2nd) with low cost, the firm durable wardrobe hinge of being convenient to install are eliminated and are replaced inferior by comparison tobacco pipe hinge.

For reaching above-mentioned purpose, the technical solution of the utility model is: adopt theory of mechanisms quadric chain principle to design structure of the present utility model, as Fig. 1 and shown in Figure 7, a kind of wardrobe hinge, comprise cabinet inner support [1], rocker plate [2], [5], Xiao's axle [3], [4], cabinet door bracket [6] and helical torsion spring [7], it is characterized in that:

Cabinet door bracket [6] and cabinet inner support [1] respectively with wood screw directly be contained in do not need on the cabinet of the grooving door and the cabinet inside wall on, so not only can not weaken cabinet door intensity but also be convenient to and install;

2. cabinet inner support [1], rocker plate [2], [5] and cabinet door bracket [6] are formed quadric chain, in this mechanism cabinet door bracket [6] and two extreme positions that are connected contact surface A of cabinet door be perpendicular to (see figure 1) be parallel to (see figure 7) cabinet inner support [1] and cabinet wall be connected contact surface B (A  B and A ‖ B); Last extreme position closes the cabinet door closure, and back one extreme position makes cabinet door full open;

3. cabinet inner support [1] is connected with Xiao's axle [4] with rocker plate [5], is equipped with to keep hinge and close tight helical torsion spring [7] on Xiao's axle [4]; This closes tight power makes the cabinet door tightly be pressed in door cashier's office in a shop when lid closes, and make the cabinet door keep Hui Guanli in artificial opening process, and it is motionless to make the cabinet door keep the cabinet door in (behind the position that promptly reaches capacity) after the full open;

4, in feature 2 described quadric chains, because of the cabinet door is connected with cabinet door bracket [6], so visual cabinet door is the expansion of a rod member in the quadric chain, when the switchboard door, the movement locus of Xiao's axle [3] that links to each other with cabinet door bracket [6] and the axial line of [4] is all arc surface, the former centre of gyration line is the axial line of Xiao's axle [3 '], and the latter's centre of gyration line is the axial line of Xiao's axle [4 ']; The movement locus of these two arc surfaces is restricting the movement locus of cabinet door, makes the cabinet door that is connected with cabinet door bracket [6] all not have friction with any position of wardrobe in switching process.

In the technique scheme, helical torsion spring is made with 65Mn hairspring steel wire cold coiling; Other part of hinge because of simple in structure all with A3 or steel 30 general steel sheets and a punching press of steel wire and cold coiling moulding, with the repeatedly punch forming process of the baroque tobacco pipe hinge of mass selling on the current market and cast aluminium forming technology relatively, the obvious volume of the utility model is little, materials are few, and be that ordinary steel section bar, moulding are easy, so material and (tobacco pipe hinge 1/2nd) cheap for manufacturing cost be the more important thing is firm durable.

In the such scheme, the wood screw circular hole on cabinet inner support [1] and the cabinet door bracket [6] also can be made into horizontal Sui Yuankong so that laterally positioning.

In the such scheme,, can carry out surperficial coating and handle for product is attractive in appearance and antirust.

In summary, it is little to the utlity model has volume, uses the ordinary steel section bar, and materials are few, moulding is easy, cost is low, excellent working performance, firm durable (suitable with the plain edition hinge), easy for installation and do not damage advantage such as cabinet door.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the assembling drawing under cabinet door closure off status (front view and vertical view, ratio are 2: 1) of embodiment.

Fig. 2 is front view and the vertical view under helical torsion spring [7] free state.

Fig. 3 is the front view and the vertical view of cabinet inner support [1].

Fig. 4 is the front view and the vertical view of cabinet door bracket [6].

Fig. 5 is the front view and the vertical view of short rocker plate [2].

Fig. 6 is the front view and the vertical view of long rocker plate [5].

Fig. 7 is assembling and the scheme of installation under cabinet door full open state of embodiment.

Assembly relation between each part of embodiment when Fig. 1 and Fig. 7 represent two extreme positions of cabinet Men Guan and Kai Shi cabinet door bracket [6] respectively.

Among Fig. 2, the short-leg head place grinding of helical torsion spring [7] is long to be a bit of of 0.5mm for 10mm is thick, settles the space so that insert.

Among Fig. 3, in order to gain in strength and rigidity, with cabinet inner support [1] crimp 2mm; For technologic convenience, intercept 1 section crooked position that is welded in this support of little steel pipe, as Xiao's axis hole that short Xiao's axle [3 '] is installed; Two other Xiao's axis hole is the cold coiling moulding.

Xiao's axis hole among Fig. 4,5,6 is all the cold coiling moulding.
