Problems solved by technology

In addition, in order to meet the urgent requirements of customers when using the product, the damping hinge applied to the product also needs to have different damping forces when it is forward and reverse, and can achieve the effect of fast forward rotation and slow reverse rotation. The damping hinge needs to be adjusted by the spring and the oil tank. The structure is complicated. The service life of the hinge is limited by the spring. Once the spring fails, the hinge will no longer be usable.

Embodiment 1

[0037] Such as figure 1 and figure 2 As shown in , the damping hinge of this embodiment includes a cylindrical housing in which a damping shaft 5 is provided and filled with damping fluid. The housing includes a housing 1 and a front end cover 2 and a rear end cover respectively located on the front and rear sides of the housing 1 3. The shell 1 and the rear end cover 3 are an integral structure. The front end cover 2 is welded to the shell 1, or it can be connected by thread or buckle. The front and rear ends of 5 are sleeved with oil-separating rings 4, the inner rings of the front and rear oil-separating rings 4 are interference fit with the damping shaft 5, and the front and rear ends of the damping shaft 5 are rotatable after passing through the oil-separating rings 4 respectively. Connected to the connecting holes on the front end cover 2 and the rear end cover 3, the outer ring of the oil separator 4 is in interference fit with the casing 1, the damping fluid in the c...

Embodiment 2

[0047] Such as Figure 4 As shown in , the difference between the damping hinge in this embodiment and Embodiment 1 is that the two strip structures with different lengths on the damping valve 6-1 are respectively located on the front and rear sides of the damping valve 6-1, and both are located at The side opposite to the damping shaft 5 of the hinge pin 6-4. One side of the vane 6-5 is opposite to the two strip structures, and is also opposite to the damping shaft 5, and this side of the vane 6-5 is set as an abutment surface.

[0048] The longer strip structure provided on the damping valve 6-1, one end is connected with the inner side wall of the damping valve 6-1, and the other end is set as the first limiting structure 6-2, and the first limiting structure 6-2 is connected with the blade The abutting surface of 6-5 is opposite, and the first limiting structure 6-2 is used to interfere with the abutting surface of the blade 6-5 when the blade 6-5 rotates to the first lim...

Embodiment 3

[0054] Such as Figure 5 As shown in , the difference between the damping hinge in this embodiment and Embodiment 1 and Embodiment 2 is that there are two protrusions on one side (front side or rear side) of the damping valve 6-1, respectively for the first limit Position structure 6-2 and second position-limiting structure 6-3, the two sides of blade 6-5 are opposite to first position-limiting structure 6-2 and second position-limiting structure 6-3 respectively, and these two sides are respectively The abutting surface of the first gear position and the abutting surface of the second gear position, the distance between the first limiting structure 6-2 and the hinge pin 6-4 is smaller than the distance between the second limiting structure 6-3 and the hinge pin 6-4 distance between.

[0055] When the blade 6-5 rotates towards the first limiting structure 6-2, the first limiting structure 6-2 collides with the abutting surface of the first gear of the blade 6-5, so that the b...

Abstract

The invention relates to a damping hinge which comprises a shell, a damping shaft is arranged in the shell and filled with damping liquid, at least two damping blocking pieces are arranged on the damping shaft, the damping shaft can drive the damping blocking pieces to rotate, at least one damping valve is arranged on the damping blocking pieces, and blades are hinged to the damping valves. The damping liquid can push the blade to rotate to open the damping valve, a first limiting structure and a second limiting structure are arranged on the damping valve, the first limiting structure is used for limiting rotation of the blade when the damping shaft rotates forwards to enable the damping valve to be in a first opening gear, and the second limiting structure is used for limiting rotation of the blade when the damping shaft rotates backwards to enable the damping valve to be in a second opening gear. And the liquid flowing channel of the first opening gear is larger than the liquid flowing channel of the second opening gear. The damping hinge can achieve the effects of fast forward rotation and slow reverse rotation, and is simple in structure, reliable in work and low in manufacturing cost.

Description

technical field [0001] The present invention relates to the technical field of hinges, more specifically to a damping hinge. Background technique [0002] With the gradual popularization of smart homes, damping hinges are more and more applied to various household products, such as curtains, roller blinds, projection screens, clothes racks, rice cooker lids, and other products that require telescopic, lifting, and flipping. Above, the damping hinge utilizes the directional flow of damping oil in the airtight container to achieve the buffering effect, which has the effect of shock resistance and noise reduction, can improve the grade of the product, and prolong the service life of the product. In addition, in order to meet the urgent requirements of customers when using the product, the damping hinge applied to the product also needs to have different damping forces when it is forward and reverse, and can achieve the effect of fast forward rotation and slow reverse rotation. ...
