Description

Floating hinge for opening door at left and right direction

The utility model relates to a kind of hinge, opens the unsteady hinge of door about specifically a kind of.

At present, the Men Jun as article such as refrigerators that uses in the life is fixed as on one side and opens, because the restriction in the riding position place of article or people's use habit make that the door of opening is inconvenient in use on one side.Chinese patent application 91203084.4 discloses the device of opening refrigerator doors about a kind of, it is characterized in that: be positioned at four jiaos axle housing of door and matched with bolt buckle on the refrigerator by the ball of the extended or retraction axle housing of spring restriction, when door is closed, the ball that is located in the axle housing heads in the bolt buckle, during unlatching, the ball of a side is that fulcrum rotates with the opposite side because of length of spring compressed skids off bolt buckle.Its deficiency is: in the opening process of door, because the weight of size of exerting oneself or door, makes the ball that rotates a side as fulcrum can deviate from bolt buckle, and door come off, and dangerous.

The purpose of this utility model will overcome above-mentioned the deficiencies in the prior art exactly, and provides a kind of in opening process, as a side of turning joint can lock effectively about open the unsteady hinge of door.

The purpose of this utility model is achieved in that the hinge that floats comprises support, main shaft, spring, its medium-height trestle has two plates that are parallel to each other, main shaft passes two plates by vertical, and rotatable or upper and lower moving, spring is positioned on the axle body of main shaft, the head that main shaft is ordered about in its elastic force effect stretches in the locating hole that matches with it, this locating hole be opened in refrigeratory body or the former arm of support plate that connects firmly with refrigeratory body on.

The utility model has the advantages that: since can about open door, so easy to use; In the door opening process, produce mutually as on side main shaft neck part of fulcrum and the support or the hole on the hat pad and to rotate, the main shaft neck part end face is limited by the support upper plate, make the main shaft axle body not move down, spindle nose can retraction door wall or support in, when therefore door rotates, an obscission can not take place, safe and reliable; Simultaneously, in the door opening process,, spring there is a radial pressure,, guarantees to be in good positioning states so produced the moment that door is closed automatically owing to rotate as the main shaft of fulcrum one side and a support or a door wall.

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

Embodiment

By Fig. 1 and Fig. 6 as seen, support (6) is the U-shaped frame, has hole (6a), (6b) on its upper and lower two symmetrical plate, and this hole and main shaft (1) are mutually movingly each other, when the rectangular opening limit of the oblate spheroid profile shaft head of main shaft (1) and hole (6a) matches, can upper and lowerly move freely; When partly match with the arc-shaped hole limit of above-mentioned hole (6a) in the axle journal position of main shaft (1), free to rotate, at this moment, the oblate spheroid profile shaft head part and the axle body of main shaft (1) can not move down, and just door body this moment (8) can only rotate with respect to main shaft (1).

Referring to Fig. 1 and Fig. 3, main shaft (1) neck has bearing pin (3), on main shaft (1) axle body of bearing pin (3) below spring (5) is arranged, and this spring (5) is positioned between the lower plate and bearing pin (3) of U type support (6).For making spring (5) produce torsional moment and reseting elasticity because of main shaft (1) relatively rotates, the bottom axle body of main shaft (1) cuts two planes along axis, simultaneously, spring (5) guarantees promptly that according to the axle body shape winding of main shaft (1) spring (5) rotates with main shaft (1); The two ends of spring (5) extend locating shim (4) respectively, and both relative fixed, locating shim (4) and spring (5) are set in main shaft (1) from top to bottom successively upward and by above-mentioned bearing pin (3) is positioned within the U type support (6) main shaft (1).U type support (6) connects firmly with door body (8), and double dot dash line is depicted as weather strip (9) among Fig. 1.

For making the better and raising abrasion resistance of supporting effect, can between the upper plate of U type support (6) and Men Bi (8), install hat pad (2) additional, referring to Fig. 1, Fig. 3 and Fig. 5, it is round table-like that the profile of hat pad (2) shows, the middle part has through hole from top to bottom, top is rectangle or the hole shape that matches with the oblate spheroid profile shaft head of main shaft (1), and the bottom is a circular port.

During use, the utility model is installed on four jiaos of door, on four former arms of cabinet (7), opens a rectangle hole slot that the oblate spheroid head of main shaft (1) is stretched into respectively.When a side is opened the door, be moved between door body (8) and former arm (7), at this moment, the head of main shaft (1) is subjected to the restriction of former arm (7) to produce downward moving, and when it broke away from former arm (7), spring (5) made it to reset; Door has been opened and this moment door rotates around opposite side, and as the unsteady hinge of opposite side of the door of supporting revolving shaft, since the door revolve open make main shaft (1) with the door body (8) rotate, thereby the oblate spheroid type head of main shaft (1) and hat pad (2) or U-shaped support (6) are relatively rotated, so just guaranteed that door can not come off in opening process.In the door opening,, produced a righting moment that is beneficial to a switching because the termination of spring (5) is subjected to radial pressure.Simultaneously, because spring (5) to the positioning action of main shaft (1), at closing time, guarantees that the head of main shaft (1) correctly falls into the rectangle hole slot of being opened on the former arm of cabinet (7).

Claims
