Abstract

The utility model discloses an automatic door-closing plug-in type hinge which can automatically close a door, and the utility model gets over an automatic door-closing helix angle and can be stopped. The circumferential matching plane surfaces of the upper and lower rotary shaft sleeves (1 and 6) of the utility model are provided with matched helix arc surfaces (2 and 4); the angle of the utility model conforms to the helix angle, and the helix angle favors convenience in entering and going out from a room through the door. According to the principle that the utility model can be lifted and lowered along a helix surface, the door can be lowered and rotated along the helix surface due to the self weight of the door after the door is opened, and the automatic closing of the door is realized.

Description

Automatic door closing hange

The utility model relates to a kind of plug-in hinge of closing the door automatically.

Hinge is a door and being connected and making the connection tumbler that rotates around doorframe of doorframe.Door after the installation is often because of the doorframe out of plumb, though the door that has has been shut, it can be opened automatically, and the door of having opened can be shut again automatically.These situations all are that people do not wish to occur.The door that we always wish to shut can not at will be opened, and the door after opening has the individual time of staying, or can shut at any time after opening, swinging door (replacing hinge with spring) can be finished above-mentioned requirements at present, but it all is office building external door, corridor door, because of the cost height, difficulty is installed, most families and office door all still are the hinge door.

The purpose of this utility model is to avoid weak point in the above-mentioned prior art, and the hinge that can stop and can close the door automatically after a kind of the opening is provided.

The purpose of this utility model can reach by the following technical programs: adopt the plug-in mounting hinge, the circumferential cooperating face upper edge axle sleeve section wall that hinge rotates up and down axle sleeve is shaped on the helicoid of cooperation.

The anglec of rotation of above-mentioned helicoid can be 70～80 degree.

The utility model is compared above-mentioned present technology can have following advantage: owing to only make the spiral section face at plug-in hinge cooperating face upper edge axle sleeve, can reach the purpose of closing the door automatically, cross arcwall face door is stopped, this hinge cost is low, and easily large tracts of land is promoted.

Fig. 1 is that the utility model can reflect up and down rotary axle box, and spiral lifting section (2,4) diagrammatic sketch when hinge axis (no) is arranged on the circumferential cooperating face of (1,6).

Fig. 2 puts arc pad (3,10) front view during the same plane of two leaf of hinge (5) rotations and in rotating shaft 9 on Fig. 1.

Fig. 3 is the rear elevation of Fig. 2.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

Shown in accompanying drawing 1, the plug-in hinge is two pages of sheet splits, one page sheet has rotating shaft 9, axle sleeve 1 with rotating shaft 9 assemblings is arranged on another page sheet, assembling back two covers (1,6) are circumferential plane work plane (3,7), according to helicoid lifting principle the utility model is the two spiral section faces (2,4) that are shaped on cooperation at the axle sleeve in work plane (3,7) upper edge (1,6) section wall own, and its anglec of rotation can be 70～80 degree.

Maximum rotation 90～120 degree because of general office and family's door, for Men Kaihou can be stopped, and consider that turnover is convenient, turnover deadweight owing to door after this angle inward that spiral section face rotation 70～80 degree can satisfy people can and make door shut along the counter-rotating of spiral section face automatically, after crossing the anglec of rotation 70～80 degree, rotation recovers the work plane that original axle sleeve plane cooperates again, door can stop, when opening the door on the door hinge upwards slide along helicoid the rising displacement arranged, doorframe will be done corresponding change like this, to adapt to the lifting of door.Can in rotating shaft 9, put corresponding pad (8,10), also can on axle sleeve, make oil filler point, make things convenient for oil injecting lubricating.

Claims

1, a kind of hinge of closing the door automatically constitutes on the plug-in hinge, it is characterized in that: circumferential cooperating face (3,7) the upper edge axle sleeve section wall that rotates up and down axle sleeve (1,6) at the plug-in hinge is shaped on the spiral section face (2,4) of cooperation.

2, hinge as claimed in claim 1 is characterized in that, the anglec of rotation of spiral section can be 70～80 degree.
