Abstract

The utility model discloses an oblique automatic closing device, which integrates the functions of a hinge, a door shaft, automatic closing and limited closing. Oblique brackets (13) and (14) are added on the hinge or the door shaft so that the shaft centers of an upper and a lower two shafts (1) and (2) are on an oblique line (5). When a door is opened, a door leaf (11) can be obliquely rotated along shaft lines and is slightly lifted, the door leaf generate dynamic force and inertia facing to a starting point due to the self gravity, and then the door automatically closes. The oblique automatic closing device has the advantage of simple and effective structure, and can be used on doors and windows of living rooms, hotels, offices, shops, etc.

Description

The tilting self closing device

The utility model relates to a kind of self closing device that is used for door and window, particularly a kind of tilting self closing device.

Because a variety of causes, people always wish to be closed automatically by open doors.Usual way adopts the Hui Li by mechanical energy such as spring, pressure, magnetic force, or achieves the goal with electric energy.But door also needs controlling organization when needing long-time opening wide, or pushes up shelves with object, otherwise will close again.

The purpose of this utility model is to overcome above-mentioned shortcoming of the prior art, and functions such as providing a kind of and gather page or leaf, door-hinge, return power apparatus, control is closed is combined into one simple and effective device, and realizes automatically closing door and window.

To achieve these goals, the utility model provides a kind of self closing device, it comprises that by two hinge set be a cover, the axle that it is characterized in that each hinge inserts in the pipe spreader respectively, pipe spreader is connected with oblique support up and down, oblique support is longer than oblique support down, makes the angled straight lines (5) at two center of rotation places and oblique support bottom line (6) be 0.1 ° of-15 ° of angle.

Device of the present utility model is achieved in that it comprises that by two hinge set be a cover, at interval certain distances, and the axle center of diaxon is on the straight line of an inclination, and this oblique line and doorframe sideline and ground line three become at the bottom of one triangle down.When opening the door, door leaf will be made tilting along the axis that tilts and rotate, and slightly promotes, because the self gravitation effect has just produced towards the power of starting point direction, door has also just had the power and the inertia of closing automatically.Angle when general door leaf opens wide fully when its unlimited angle surpasses 90 °, will produce the power of starting point dorsad about 100 °, stop to rotate to the direction of closing, and reaches the purpose of phase down.When people came in and went out traditionally, door was not unlimited fully, and this just provides shortcut simply and easily for the purpose that realizes this device.So general turnover, door will be closed automatically, when needing long-time opening wide, opens wide door just passable fully.

The utility model has the advantages that: simple in structure, the inclined support of length under the weak point on increasing on ready-made hinge or the door-hinge, making up and down, two axles are tilted on the line by certain angle.Make easily, save material, simple in the use, be not easy malfunctioning damage, cheap, wide application, easy as hinge by dress, practical reliable.

Concrete structure of the present utility model is described further in conjunction with the accompanying drawings.Accompanying drawing is the structural representation of the utility model tilting self closing device.Two hinges that match up and down are to insert pipe spreader (12) by rotating axle (1) respectively with (2) to be connected with (14) with oblique support (13) with (22) in the drawings.The support (13) of pipe spreader (12) is longer than the support (14) of top with the fixing angle of axial line (5), makes axle (1) and spool (2) on the straight line (5) of an inclination.When door leaf (11) opens wide, will make tilting along the axial line (5) that tilts rotates, door leaf can slightly promote, because the gravity of self, just produced the power and the inertia that rotate towards the starting point direction, and closed automatically, when door leaf opens wide above 90 °, then produce the power of starting point dorsad, door will phase down.Be advisable between 0.1 °-15 ° in the angle that parallax (5) and oblique support bottom line (6) form, because of the different size of door and window difference to some extent, Hui Li also can increase when angle was excessive, and door damages easily, also has very big noise.

Claims

1. tilting self closing device, it comprises that by two hinge set be cover, it is characterized in that, the turning cylinder of each hinge inserts in the axle sleeve respectively, pipe spreader is connected with oblique support up and down, oblique support is longer than oblique support down, makes the straight line (5) of the inclination at two center of rotation places and oblique support bottom line (6) be 0.1 ° of-15 ° of angle.
