Embodiment Construction

[0038] Examples, see figure 2 with image 3 Shown: the double-hinge structure of super anti-friction, including 2 shaft plates 10, 1 gear seat 20, 1 friction plate 30, some elastic washers 40 and other parts. The shaft plate 10 is generally used to respectively fix the motherboard and the display screen of electronic products such as notebook computers.

[0039] in:

[0040] The right part of the shaft plate 10 is provided with a gear shaft 11 extending horizontally to the right. The gear shaft 11 includes a gear 12, a special-shaped shaft 13, a transition shaft 14, and a connecting screw 15 from left to right. The special-shaped shaft 13 refers to a shaft whose section is non-circular. In this embodiment, the section of the special-shaped shaft 13 is waist-shaped, that is, a plane parallel to the axis of the blank shaft is formed on the front and rear sides of a blank shaft with a circular section. Moreover, the outer diameter of the gear 12 should be larger than the di...

Abstract

The invention discloses a double-hinge structure with super wear resistance. The double-hinge structure comprises two shaft plates, a gear seat, a friction plate and a plurality of elastic washers, wherein gear shafts horizontally extending rightwards are arranged on the right portions of the shaft plates, and each gear shaft sequentially comprises a gear, a special-shaped shaft, a transition shaft and a connecting screw from left to right; penetrating holes are formed in the friction plate; an idle wheel is arranged between the two gears; the two special-shaped shafts are sleeved with first friction plates and second friction plates, the penetrating holes are located between the first friction plates and the second friction plates, the first friction plates and the second friction platescannot rotate relative to the corresponding special-shaped shafts, and the special-shaped shafts can rotate relative to the corresponding penetrating holes; limiting nuts are connected to the connecting screw rods in a threaded mode, and the transition shafts are sleeved with the elastic washers; and a plurality of oil grooves are evenly distributed in the friction plate around the penetrating holes, the oil grooves are filled with lubricating oil, and the extending directions of the oil grooves pass through the centers of the corresponding penetrating holes and then are distributed in a radial mode. The double-hinge structure has the advantages of smooth operation and long service life.

Description

technical field [0001] The invention relates to the technical field of electronic product accessories, in particular to an ultra-friction-resistant double hinge structure. Background technique [0002] Double hinges are often used in electronic products such as laptops to open and close the display screen compared to the motherboard. Among them, in order to achieve the effect of making the display screen and the main board have an arbitrary angle, it is mostly realized through the friction force generated between the friction plate and the friction plate. At the same time, most of the friction plates are provided with oil grooves, and lubricating oil is arranged in the oil grooves to make the parts run smoothly. The common oil tank is either a spiral oil point structure or a matrix oil point structure, respectively as Picture 1-1 with Figure 1-2 shown. Its disadvantages are: the wear resistance is not ideal enough, and it is prone to beating. Contents of the invention...
