Abstract

The utility model belongs to building hardware which is used in wings. The utility model can solves the problem that doors and windows can stop and position at multiple locations by opening or shutting automatically without a door hook or a window hook. The hinge has the advantages of low total cost, simple structure, and good stopping and positioning reliability; the utility model is characterized in that the interior of pin holes of an inner and an outer hinges is provided with a stopping mechanism, and spacing lug bosses are respectively arranged on a casing and a ball seat; a torsion spring is arranged on a gear shaft which is arranged between the two lug bosses. The utility model not only can be used for automatically opening or shutting, stopping and positioning in the windows and the doors, but also can be used for automatically opening or shutting and stopping and positioning in boxes and cabinets. When the utility model is used as a window hinge, the utility model can make ' hallway wind ' blow to indoor, and the utility model is not only convenient but also safe in wiping windows.

Description

Hinge

The utility model belongs to a kind of architectural hardware that is used for wing, is particularly suitable for the automatic unlatching of door, window, case and cabinet or closes and stop location is used.

All with gate stop or window catch stop location, can only locate on a certain position like this by door and window after opening with hand for wings such as door and window at present.Though adopt adjustable window catch to locate on 2 or 3 positions, the requirement of opposite house or window different opening can not be satisfied still very little in orientable position.And there have been gate stop or window catch that total cost is risen and hindered attractive in appearance.Japan Patent " hinge " (clear 60-258387) provides a kind of hinge that can spend stop location on two positions at 90 degree and 180, saved gate stop or window catch, but under the bigger situation of wind-force, the reliability of stop location can not guarantee.

The purpose of this utility model will provide a kind of exactly and can open automatically or close and can stop locate on a plurality of positions without hook, and can guarantee the hinge of stop reliability of positioning under large wind.

The utility model is to adopt following structure to finish above-mentioned purpose:

One stop mechanism is housed in the pin-and-hole of inside and outside hinge, and stop mechanism is made up of housing, gear shaft, locking plate, cover plate, flat spring and button.When flat spring moved under button drives, locking plate was thrown off with the tooth of gear shaft under the effect of flat spring, and hinge is free to rotate.When flat spring moved down under button drives, flat spring was pressed into the flank of gear shaft to locking plate, and gear shaft is by two-way stuck, and hinge can not rotate.

Now in conjunction with the accompanying drawings hinge is described in further detail:

Figure (one): the sectional view during hinge stop.

Figure (two): the sectional view when hinge is thrown off stop.

Figure (three): A-A sectional view.

Figure (four): B-B sectional view.

Figure (five): C-C sectional view.

Shown in figure (), housing (4) is contained in the pin-and-hole of interior hinge (7), by two screws (3) housing (4) and interior hinge (7) is fixed together.Gear shaft (5) passes housing (4), and an end is contained in the hole of outer hinge (1), and is fixing by alignment pin (2), and the end steel ball (8) interior with being contained in ball seat (9) contacts, and ball seat (9) is fixed on the outer hinge (1) by alignment pin.One end of gear shaft (5) also can directly be packed in the hole of ball seat (9).

Shown in figure (three), the number of teeth of gear shaft (5) is 6～24 teeth, the number of teeth very little, the position of stop location is very little.The number of teeth is too much, and the hinge jaw hole dimension is too big, seems out of proportion.With the hinge of general door of what and window, the number of teeth is the most suitable with 8～18 teeth, and at this moment the size of hinge pin-and-hole is less, and the positional number of stop location can be satisfied the demand substantially.

Shown in figure (four), on housing (4) and ball seat (9), a positive stop lug boss is arranged respectively, the corner dimension of positive stop lug boss is 90 degree.The positive stop lug boss corner dimension is advisable in 90 degree～120 degree scopes.Positive stop lug boss on housing (4) and the ball seat (9) plays limit positioning action.Lost efficacy or forgot under the situation of stop locking when stop, and prevented door and window bump frame and damage door and window.

Shown in figure (), (two) and (five), locking plate (11) and cover plate (6) are contained in respectively in the dimple of housing (4), and flat spring (12) is pushed down locking plate (11) and cover plate (6).The square hole of flat spring (12) embeds in the boss of button (13), moves with button (13).When moving on the button, hinge can rotate automatically.When button moved down, hinge was locked by stop, can not rotate.

Shown in figure (one), (two), (four), on the gear shaft (5) between housing (4) and the ball seat (9), a torsion spring (14) is housed, one end of torsion spring inserts in the groove of housing (4) positive stop lug boss, one end inserts in the groove of ball seat (9) positive stop lug boss, because the dress method difference of torsion spring (14), can make hinge open automatically or close automatically, open automatically or close automatically thereby drive door and window.If hinge pairing is used, and the torque magnitude of torsion spring (14) is different, and torsional direction is opposite, and is because the partial offset of torsion can make door and window open slowly or close, safer to guarantee.

A kind of hinge that the utility model provides can automatically be opened or close the doors and windows and can stop locate the good reliability of stop location on a plurality of positions. When the distance of hinge pin-and-hole and window frame reaches certain distance, enough big slit is just arranged after windowing, " passageway wind " just can be blown into indoorly like this, because enough big slit arranged, hand can stretch out from stitch wipes window, safe and convenient. The utility model has saved on the common door and window the fixedly hook of usefulness, totle drilling cost is reduced and makes profile more attractive in appearance. The utility model not only can be used for the unlatching of door and window or close and the stop location, and can be used for the automatic unlatching of case and cabinet or close and stop is located.

Claims

1, a kind of hinge that is applicable to door, window, case and cabinet is characterized in that in the pin-and-hole of inside and outside hinge (7), (1) stop mechanism being housed, and stop mechanism is made up of housing (4), gear shaft (5), locking plate (11), cover plate (6), flat spring (12) and button (13).

2, it is characterized in that by the described hinge of claim 1 number of teeth of gear shaft is 6～24 teeth, the optimum number of teeth is 8～18 teeth.
