Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Referring to fig. 1 to 4, the compact damping hinge includes a first plate 6, a second plate 5, a hinge shaft 7 and a damper 4, the hinge shaft 7 is a screw, the damper 4 is a plurality of elastic mesons 3, the first plate 6 and the second plate 5 are parallel and opposite, the hinge shaft 7 penetrates through the first plate 6 and the second plate 5 from the middle to hinge the first plate 6 and the second plate 5 into a whole, the plurality of elastic mesons 3 forming the damper 4 are serially connected to the hinge shaft 7 to provide axial pressure, and the axial pressure makes the second plate 5 approach the first plate 6, thereby preventing the first plate 6 and the second plate 5 from rotating relatively. When an external force for relative rotation is applied to the first plate 6 and the second plate 5 to overcome the pressure of the damper 4, the first plate 6 and the second plate 5 rotate relative to each other, and when the external force is stopped, the first plate 6 and the second plate 5 are kept at the rotated positions due to the pressure of the damper 4. In this way, the first plate 6 and the second plate 5 can be conveniently adjusted and maintained at any angle. In addition, the first plate body 6 and the second plate body 5 which are parallel to each other and are right opposite to each other enable the whole size of the damping hinge piece to be small, the structure is compact, and the damping hinge piece can be suitable for application occasions with small installation space.

The first plate body 6 is provided with a plurality of first connecting portions 11, the edge of the second plate body 5 is provided with a flange 8 extending in a direction away from the first plate body 6, and the flange 8 forms a connecting groove 9 in the second plate body 5. During the use, install first plate body 6 at treating articulated first body (like the body of rod of fan) through first connecting portion 11, then will treat articulated second body (like the head of fan) joint at second plate body 5 through spread groove 9, accomplished the articulated of first body (like the body of rod of fan) and second body (like the head of fan) promptly, it is very convenient to install. The first connection portion 11 is preferably a connection hole or a connection post.

An auxiliary connecting part 10 is further arranged on the second plate body 5, and the auxiliary connecting part 10 is preferably a connecting hole or a connecting column. After the second plate 5 and the second body are further connected by the auxiliary connecting portion 10, the combination of the second plate 5 and the second body is more reliable.

The hinge shaft 7 is further provided with a flat spacer 2 between the second plate body 5 and the first plate body 6, and the flat spacer 2 separates the first plate body 6 from the second plate body 5, so that the frictional resistance between the two plate bodies can be reduced, and the adjusting resistance can be reduced. Similarly, the hinge shaft 7 is further provided with the flat mesons 2 on two sides of the damper 4, and the flat mesons 2 can also play a role in reducing the adjusting resistance.

Further the elastic meson 3 constituting the damper 4 is arranged in said attachment slot 9, which further reduces the overall volume of the damping hinge.

In the above embodiment, the hinge shaft 7 is a screw, and the elastic meson 3 constituting the damper 4 is mounted on the hinge shaft 7 through the nut 1. In this way, the output pressure of the damper 4 can be easily adjusted by adjusting the nut 1. It should be understood that the damper 4 may be a coil spring, and the damper 4, the first plate 6, and the second plate 5 may be held on the hinge shaft 7 by riveting or the like.

In the above embodiment, the first plate 6 is fixed to the hinge shaft 7 by the nut 1, and the second plate 5 is rotatably mounted on the hinge shaft 7. It will be appreciated that the same effect can be achieved by mounting both the first plate 6 and the second plate 5 rotatably on the hinge shaft 7, or by mounting the first plate 6 rotatably on the hinge shaft 7 and the second plate 5 fixed to the hinge shaft 7. Further, the above-described embodiment has the damper 4 disposed on the outer side of the second plate 5, it being understood that the damper 4 may be disposed between the second plate 5 and the first plate 6, and the damper 4 may be disposed on the outer side of the first plate 6 when the first plate 6 is rotatably mounted on the hinge shaft 7.

The compact damping hinge is particularly suitable for small household appliances such as table fans, floor fans, table electric heaters, floor electric heaters and the like.

When being applied to the fan, pass a plurality of first connecting portion 11 on the compact damping articulated elements respectively with the screw and install the body of rod at the fan first plate body 6, then pass the head joint of fan at second plate body 5 through spread groove 9, pass the head locking of supplementary connecting portion 10 with second plate body 5 and fan with the screw can. When the fan is used, the head elevation angle of the fan can be adjusted only by applying external force to the head of the fan to overcome the pressure of the damper 4, and the head of the fan can be kept at the elevation angle due to the pressure action of the damper 4 after the external force is stopped being applied, so that the fan is very convenient to use.

Similarly, when being applied to the electric heater, pass a plurality of first connecting portion 11 on the compact damping articulated elements respectively with the screw and install the body of rod at the electric heater first plate body 6, then pass the head joint of electric heater at second plate body 5 through spread groove 9, pass the head locking that supplementary connecting portion 10 will second plate body 5 and electric heater with the screw can. During the use, only need to apply external force to the head of electric heater and overcome the pressure of attenuator 4, can adjust the head angle of elevation of electric heater to after stopping applying external force, because the pressure effect of attenuator 4, the head of electric heater can keep at this angle of elevation, and it is very convenient to use.

The present invention has been described in detail with reference to the specific embodiments, and the detailed description is only for assisting the skilled person in understanding the content of the present invention, and can not be understood as the limitation of the protection scope of the present invention.
