Abstract
The utility model relates to a box-type hinge for a door, which belongs to the door hinge type and is particularly suitable for anti-pick doors. The utility model is composed of a fixing plate (1), a hinge page plate (2), a rotary shaft (3), steel balls (4), a shaft sleeve (5), and a hinge seat (6). The utility model is characterized in that the hinge seat forms a hollow box shape, the hinge page plate forms a bow shape, and the rolling steel balls are arranged between the rotary shaft and the shaft sleeve. Therefore, the load bearing area is reduced, the abrasion and the friction are decreased, and the noise of friction is overcome; furthermore, the utility model has the advantages of flexible and free rotation, and long service life.
Description
The hinge class that belongs to door.
At present, be used for the particularly anti-rotation folding hinge of forcing open the door of door, make the dismountable and non-removable two kinds of form of structure of door leaf.Dismountable structure generally by be installed in hinge seat on the doorframe respectively, be fixed on the axle sleeve on the hinge seat and be installed in the hinge page or leaf plate on the door leaf, the rotating shaft that is fixed on the hinge page or leaf plate is formed.When doorframe and door leaf assembling, only need the axle sleeve insertion that the rotating shaft on the door leaf is aimed on the doorframe is got final product.This structure majority is to contact the own wt that bears door leaf by the shaft shoulder in the rotating shaft with the end face of axle sleeve, contact surface can produce friction and wearing and tearing in the folding rotation process, also can produce the friction noise, during serious wear, door leaf is sunk, have influence on the driving fit between doorframe and the door leaf and the centering effect of lockset.
The purpose of this utility model is to provide a kind of door leaf dismountable, load-bearing contact surface intensity height between the rotating shaft of hinge and the axle sleeve, and contact area is little, rubs and weares and teares for a short time, can not produce the friction noise, a kind of Box-type hinge of novel structure.
The utility model is achieved in that a kind of is used Box-type hinge, it is by the hinge seat that is installed on the doorframe, be fixed on the axle sleeve on the hinge seat, be installed in the hinge page or leaf plate on the door leaf, the rotating shaft that is fixed on the hinge page or leaf plate is formed, it is on an empty stomach square box-like that feature is that hinge seat is, and the front of box and a side are opened wide.When it was installed on the left frame of doorframe, then the right flank of box was for opening wide.When it was installed on the left frame of doorframe, then the left surface of box was for opening wide.Axle sleeve is being fixed in the bottom surface of box, and the lower end of axle sleeve has at the bottom of the sealing.The sylphon of hinge seat is built-in with hinge page or leaf plate, and hinge page or leaf plate is hunchbacked shape, and its front end is equipped with rotating shaft.The lower end of rotating shaft be local contact of sphere at the bottom of the sealing of axle sleeve and cooperate and through intensive treatment, the hunchbacked other end is equipped with fixed head.For reducing friction, can coat sliding agent in the axle sleeve bottom, also can further be equipped with a rolling steel balls in rotating shaft and at axle sleeve sealing the end.
The utility model has the advantages that,, be modified into the sealing of rotating shaft and axle sleeve and be the sphere load-bearing in the end the end face load-bearing of the rotating shaft shaft shoulder in the prior art and axle sleeve; Particularly adopt in rotating shaft and at axle sleeve sealing the end and be equipped with rolling steel balls, both reduced the load-bearing area, reduced wearing and tearing and friction again, overcome the friction noise, novel structure, folding light and flexible, long service life.
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
Fig. 1 uses the Box-type hinge front view;
Fig. 2 is an A-A sectional view among Fig. 1;
Sequence number is described as follows among the figure: the 1st, and fixed head; 2 hinge page or leaf plates; The 3rd, rotating shaft; The 4th, steel ball; The 5th, axle sleeve; The 6th, hinge seat.
A kind of Box-type hinge structure that is mounted in pick-proof every frame left border that present embodiment provides, the front and the right flank of Box-type hinge seat (6) open wide, be welded with axle sleeve (5) in the bottom surface of hinge seat, rotating shaft (3) is an overall structure with hunchbacked shape hinge page or leaf plate (2) and fixed head (1), by processing after the hot investment casting.The lower end of rotating shaft (3) is processed into the concavity sphere and is contacted with the surface point of steel ball (4).During installation hinge seat (6) is welded on the doorframe left border, fixed head (1) is screwed on door leaf, and the maximum opening angle of door leaf can reach 95 degree.
The utility model is specially adapted to prized up-proof door, also can be used on other doors.
