Description

Built-in hinge

The utility model relates to the bin door and window and connects the Built-in hinge of using usefulness such as hinge, particularly bin door and window.

The Built-in hinge of existing bin door and window, its kind and form of structure are various, but exist mostly or take up room big, or complex structure, or cut with scissors the complex structure of conjuncted installation portion, or require the conjuncted installation portion of hinge that enough thickness must be arranged, or shortcoming such as complexity is installed.

Given this, the purpose of this utility model be to provide a kind of simple in structure, take up room less, easy for installation, hide the good concealed type hinge of property.

The utility model adopts between joining two hinge bodies and is the slide block of the circular arc that is slidingly matched and the slideway structure of circular arc is realized its purpose.

Built-in hinge of the present utility model (referring to accompanying drawing), comprising can be respectively and two hinge conjuncted joining two gusset pieces (3,7), has to link to each other with two gusset pieces respectively and be the slide block (1) of the circular arc that is slidingly matched and the slideway (4) of circular arc mutually.

Above-mentioned slide block is rod, and above-mentioned slideway is the tubular of cover plate (5) that circular arc is arranged, and the spacer pin (2,6) that matches is respectively arranged on slide block and cover plate.

Above-mentioned slide block can be tubular, above-mentioned slideway can be rod.

Above-mentioned slide block cooperates with slideway, and two gusset pieces (3,7) are on the isoplanar when closure state.

Above-mentioned slide block cooperates with slideway, and two gusset pieces (3,7) are overlapped when closure state.

Said structure of the present utility model makes it have following advantage and effect.

One, hinge of the present utility model, can be installed in the medial surface of hinge such as bin door and window connection portion, when folding, the slide block of circular arc slides along the slideway of circular arc, and its hiding property is good, rotates flexibly, axis of rotation becomes virtualization, connect reliably, it is less to take up room, and the closed when the bin door and window is closed is good.

Two, hinge of the present utility model only needs slide block, slideway and gusset piece thereof to constitute, and it is simple in structure, and manufacturing process is simple, and is easy for installation.And appearance and modeling is attractive in appearance just as the butterfly sample.

Built-in hinge of the present utility model can be used as the hinge of bin door and window, is specially adapted to small-sized chamber, as phone cabinet etc., can guarantee the positive connection of the folding hinge of phone cabinet etc., opens flexibly, closes.

Below, the utility model is further described to use embodiment and accompanying drawing thereof again.

Embodiment 1

A kind of Built-in hinge of the present utility model, as shown in drawings.Constitute by slide block and slideway etc.

Above-mentioned slide block 1 is circular-arc rod, is fixed with the spacer pin vertical withcircular arc 2 at an end of slide block, at the other end of slide block thegusset piece 3 of into a single integrated structure square plate shape is arranged, and is shaped on screw hole on gusset piece.

Above-mentionedslideway 4, be circular-arc tubular, the side of slideway edge is combined with thecover plate 5 of circular arc, is fixed with the spacer pin vertical with circular arc 6 in the cover plate inboard of an end of slide rail, and this spacer pin 6 andspacer pin 2 on the slide block 1 match and synthetic slide block 1 can not deviate from from slideway.At the other end ofslideway 4gusset piece 7 of into a single integrated structure square plate shape is arranged, on gusset piece, be shaped on screw hole.

Above-mentioned slide block also can be made tubularly, and then slideway is made and the corresponding rod of tubular slide block.

The utility model can have two kinds of installment states:

A kind of is to be used for two hinge hinge connection portions of conjuncted 8,9 to be conplane field boundary and to close, as doorframe and door leaf, window frame and sash, during installation with thegusset piece 3,7 of slide block 1 andslideway 4, usescrew 10 respectively, by the screw hole on it be packed in two the hinge conjuncted on, and make two gusset pieces on the isoplanar, and the free end of slide block 1 is enabled flexible slip from thepore 11 that the free end ofslideway 4 inserts slideway, load ontocover plate 5 at last, under the cooperation of the spacer pin 6 of thespacer pin 2 of slide block and slideway, slide block can not deviate from slideway.

Another kind is to be used for two hinges conjuncted 12,13 hinge connection portion is vertical field boundary and closes, as casing and case lid, box body and lid, can be in advance make theinstallation pit 14 that matches with this hinge in therein thehinge connection portion 13, during installation with thegusset piece 3 of slide block 1 andslideway 4,7, usescrew 10 respectively, by the screw hole on it be packed in two the hinge conjuncted on, and make two gusset piece overlaids, and the free end of slide block 1 is enabled flexible slip from thepore 11 that the end thatgusset piece 7 is arranged ofslideway 4 inserts slideway, load ontocover plate 5 at last, under the cooperation of the spacer pin 6 of thespacer pin 2 of slide block and slideway, slide block can not deviate fromslideway.Seal pits 14 withend plate 15 and panel 16 after the installation.

The slide block of the utility model hinge is 92 ° ± 1 ° with respect to the nominal corner of slideway
