[0006] The main purpose of the present invention is to provide a double-axis hinge that can rotate alternately. Grooves are used to replace the two sets of stoppers of the two mandrels shown in the prior art, and the setting of the fan-shaped stop rings shown in the aforementioned prior art is omitted to produce the same alternate stop effect, thereby facilitating manufacturing and reducing Processing procedures and components to reduce production costs

Embodiment Construction
[0035] see Figure 1 to Figure 4b , the present invention discloses an alternately rotatable biaxial hinge, which includes a pivot seat 1, a first mandrel 2, a second mandrel 3, a torsion component 4, and two sets of torsion auxiliary adjustment units 5.
[0036] The pivot base 1 has a lower through hole 11 and an upper through hole 12 in the axial direction, and at least one side, such as the right side, protrudes a pair of side walls 13 oppositely, and two shaft pins 16 pass through the pair of side walls at intervals 13, so as to pivotally connect an axial swing member 14 and a radial movable member 15 respectively at intervals. Wherein among these shaft bolts 16, a first shaft bolt 16 is pivotally connected to the bottom and top of the axial swing member 14, and a lower guide tenon 141 and an upper guide tenon 142 are protruded in the radial direction respectively, and a second shaft bolt 16 A lower arc surface 151 and an upper arc surface 152 are formed radially below a...

An alternately rotatable biaxial hinge includes a pivot seat, a first spindle and a second spindle. At least one side of the pivot seat is pivotally connected with an axial swing member and a radial movable member at intervals; the first mandrel extends a first shaft passing through the pivot seat, and is provided with a first guide groove and A first engagement groove, a first start end, a first end end, a right stop end and a left stop end respectively formed in the first guide groove for the axial swing member to abut against and form a stop function, the When the first engaging groove is engaged with the radial movable part, the locking of the first spindle is formed, and the second spindle is unlocked; the second spindle extends a second shaft passing through the pivot seat rod, and is provided with a second guide groove and at least one second engagement groove, a second start end and a second terminal end respectively formed in the second guide groove for the upper guide tenon to abut against and form a stop function, at least A second engagement groove locks the second mandrel when engaged with the radial movable part, and unlocks the first mandrel so that the mandrels can alternately rotate.
Description
technical field [0001] The invention relates to a biaxial hinge, in particular to an alternately rotatable biaxial hinge. Background technique [0002] A general clamshell electronic device, such as a notebook computer or a mobile phone, is provided with a hinge, and the hinge allows the screen to be opened or closed relative to the main body. Most of the existing hinge structures are uniaxial, and usually include a pivot seat fixed on the screen of the electronic device. The pivot seat is provided with a shaft hole for a mandrel to pass through. The mandrel is fixed on the A body of an electronic device; a screen of the electronic device is opened or closed relative to the body through the rotation of the pivot seat relative to the spindle. [0003] In order to provide convenience for the operation of the screen or the body, those skilled in the art have developed a biaxial hinge device, which is respectively sleeved on two mandrels through two intermeshing gears, and the ...
