Abstract
The invention discloses a hinge capable of automatically closing with a buffer device. The hinge comprises an upper hinge with a vane and a lower hinge jacket with a vane as well as a fixed core which is rigidly connected with the lower hinge jacket, wherein lower hinge jacket is connected with the upper hinge. A moveable core and a spring are sequentially connected between the fixed core and the lower hinge jacket. The spring which is fixed in the lower hinge jacket drops according to the gravity and reduces the impact to a peripheral frame through the buffer function when drops. Meanwhile, as the fixed core is matched with the moveable core, a door can be ensured in any position with 90-180 degrees when the door is opened in a large angle. When the opening angle is smaller than 45 degrees, the acting force of the spring acts on the moveable core and a slow changing bevel of the moveable core transfers the force to the upper hinge so that the door can be closed slowly. Due to differential design of the fixed core and the moveable core, the spring is compressed by the moveable core when the door is opened in a small angle so that the door is ensured not to be lifted in the range of the door frame, and therefore, the application range is expanded.
Description
Technical field
The present invention relates to a kind of hinge with ability auto-closing of buffer.
Background technology
Usually, door is rotatably connected on the doorframe through the door hinge device with damping function, and this door hinge device can suitably be kept the opening and closing speed of door; Thereby can prevent because of the too fast switching of door causedly, one Chinese patent application numbers 200620077518.6 discloses a kind of hinge that can close the door automatically, comprises hinge shaft sleeve down; Following hinge fixing hole, following hinge iron plate fuses, the upper hinge axle sleeve; Upper hinge iron plate, the upper hinge fixing hole fuses, and above said hinge shaft sleeve down, is provided with the Lower shaft sleeve spirality; Below said upper hinge axle sleeve, be provided with the Upper shaft sleeve spirality, in following hinge shaft sleeve and the upper hinge axle sleeve hinge axis be installed.
Because the defective that above-mentioned existing hinge exists, the design people actively study innovation, and the hinge in the hope of the ability auto-closing with buffer of founding a kind of new structure makes it have more practicality.
Summary of the invention
Main purpose of the present invention is; Overcome the defective that existing hinge exists; And provide a kind of new structure have buffer can auto-closing hinge; Technical problem to be solved is to make it lean on gravity to descend to have the function of buffering simultaneously, thereby is suitable for practicality more, and has the value on the industry.
The object of the invention and solve its technical problem and adopt following technical scheme to realize.A kind of hinge according to the present invention's proposition with ability auto-closing of buffer; Comprise blade-carrying upper hinge and the blade-carrying hinge overcoat down that is connected with this upper hinge; It also comprises, a fixed core, and this fixed core and said hinge overcoat down are rigidly connected; Between this fixed core and said following hinge overcoat, be connected with slide core and spring in turn, this spring is fixed in the said hinge overcoat down.
Aforesaid hinge with ability auto-closing of buffer; Wherein, said upper hinge and said hinge overcoat down flexibly connect, and said upper hinge external surface is provided with convexity; In the process that upper hinge descends, can following down, the hinge overcoat contacts; Reduced the compression of upper hinge, prolonged the application life of spring, also increased the aesthetics of hinge simultaneously spring.
Aforesaid hinge with ability auto-closing of buffer; Wherein, said fixed core be a cylinder shape structure, an end face of this fixed core is a platform; Be provided with sudden turn of events formula inclined-plane along this platform, the sidewall of said fixed core is provided with two grooves that flexibly connect said slide core.
Aforesaid hinge with ability auto-closing of buffer, wherein, said fixed core engages said slide core.
Aforesaid hinge with ability auto-closing of buffer, wherein, said slide core is half frame type, comprises the bottom surface, is arranged on two columns on this bottom surface, the top of said column is gradual formula inclined-plane.
By technique scheme, the hinge that the present invention has the ability auto-closing of buffer has advantage at least:
Dependence gravity descends, and through pooling feature, has reduced when descending the impact to the periphery sides frame; Adopt fixed core and slide core to cooperatively interact simultaneously, under the wide-angle opening, can guarantee that door rests on greater than on 90 ° to 180 ° the optional position; Thereby it is easy to use; When opening angle less than 45 ° situation under, the active force of spring acts on the slide core, the gradual formula inclined-plane of slide core with power pass to upper hinge makes the door can slowly close.Because the differential design of fixed core and slide core has guaranteed door slide core compression spring under the situation that low-angle is opened, guarantee that door does not raise, and has enlarged the scope of application in the doorframe scope simultaneously.
In sum, the hinge of the ability auto-closing with buffer of special construction of the present invention, it has above-mentioned many advantages and practical value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of manual, below with preferred embodiment of the present invention and conjunction with figs. specify as after.
Description of drawings
Fig. 1 for the present invention have buffer can auto-closing the exploded view of hinge.
Fig. 2 is the sketch map of fixed core of the present invention.
Fig. 3 is the structural representation of slide core of the present invention
The specific embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, specific embodiments of the invention specify as after.
As shown in the figure, a kind of hinge with ability auto-closing of buffer comprises blade-carrying upper hinge 1 and the following hinge overcoat 5 that has blade 7 that is connected with this upper hinge 1; It also comprises, a fixed core 2, and this fixed core 2 is rigidly connected with following hinge overcoat 5; Between this fixed core 2 and following hinge overcoat 5, be connected with slide core 3 and spring 4 in turn, this spring 4 is fixed on down in the hinge overcoat 5, and upper hinge 1 flexibly connects with following hinge overcoat 5; In order to reduce the compression of 1 pair of spring 4 of upper hinge; Upper hinge 1 external surface is provided with convexity 6, and hinge overcoat 5 contacts under can following in the process that upper hinge 1 descends, and has prolonged the application life of spring 4.
Fixed core 2 be a cylinder shape structure, an end face of this fixed core 2 is a platform, is provided with sudden turn of events formula inclined-plane 9 along this platform 8; The sidewall of fixed core 2 is provided with two grooves 10,11 that flexibly connect said slide core, and slide core 3 is half frame type, comprises bottom surface 13; Be arranged on two columns 12 on this bottom surface 13, the top of column 12 is gradual formula inclined-plane, fixed core 2 slide core 3 that is fixed; In actual use, door can rest on a certain position in opening more than 90 °, thereby easy to use; When opening angle less than 45 ° situation under, the active force of spring 4 acts on the slide core 3, the gradual formula inclined-plane of slide core 3 with power pass to upper hinge 1 makes the door can slowly close; Simultaneously because the differential design of fixed core 2 and slide core 3; Guaranteed door slide core 3 compression springs 4 under the situation that low-angle is opened, guaranteed that door does not raise, and has enlarged the scope of application in the doorframe scope.Opening angle greater than 45 ° situation under, the lifting sliding rail of upper hinge 1 inner chamfer can guarantee that upper hinge 1 raises rapidly, puts aside enough energy and uses when closing.
