New description: [New technical field] This is a kind of pulley-locked double-axis hinge, especially a kind of hinge with double shaft and reversible 360 degree, suitable for clamshell electronic devices. [Prior Art] 1 Also used for a cymbal electronic product, such as a hinge of a notebook computer, a mobile phone, or an electronic book reader, to enable the screen to be opened or closed relative to the base. The conventional shaft structure is mostly single-axis type, and usually includes a bracket fixed to the screen of the electronic product. The bracket has a circular shaft hole for a mandrel to be inserted, and the spindle is fixed to the base of the electronic device by a fixing seat. By rotating the bracket relative to the mandrel, the honor screen can be opened or closed relative to the base. The single-axis shaft itself can be rotated by 36 degrees, but it is limited by the design of the screen and the base of the base. When the screen casing and the outer casing open to 180 degrees, they interfere with each other and cannot be turned over more than 18 degrees. Even a 360 degree reverse stack. At present, portable computers have many touch-type or handwriting input operations, and the screen and the base can be flipped by more than 18 degrees, and even 36 degrees of reverse overlap to facilitate the holding of touch operations. A two-axis design is produced. For example, as shown in the new patent "Two-axis pivoting device" of the Republic of China Announcement No. M324951, the two pivots are connected by a connecting bracket, and the bracket slots are connected, and the pivoting sleeves are positioned in the positioning slots. The ring, as well as several pieces of the crest, provide resilience to force the positioning ring to lie in the positioning groove. The two rotating shafts have the same structure and the same torque. When applied to a notebook computer with a touch screen, the notebook computer can have the same type of use, or the screen and the keyboard can be rotated by 360 degrees. Reverse stacking for easy touch operation on the screen. However, in actual use, it is impossible to determine which one of the M438797 axes will rotate. When the notebook computer is in normal use, as shown in Fig. 6, when the curtain is opened, the upper wire first rotates, and the connecting bracket remains erect. Then, in the process of adjusting the opening angle, the connecting bracket may be driven and the pivoting of the phase f below, so that the position of the upper frame shaft will move, so that the solid touch on the upper touch (four) is not only a lion, but also turn , ^ makes the user feel unstable. Although, the above-mentioned torsional force can be set smaller than the following torsion force, so that the upper pivot first rotates 'but if the torque reduction rate of the lower pole sleeve is larger than the upper one, the hinge cannot be ensured after using for a period of time. The sequence and manner of operation of its switches. Moreover, 'usually, the electronic device will have a pivot on each of the left and right sides. If the two sides of the hub have different recession rates, it is possible that one side of the screen is rotated when the screen is opened, and the other side is pivoted below, causing the curtain to turn. The situation. Therefore, it is not ideal to use the torque to control the order of pivoting. [New content] The main purpose of the pivoting work is to provide a kind of pulley-locked double shaft, which is engaged with the first engaging cam by a movable pulley, or: first, engaging cam fitting The lock is limited to (4) - the rotation of the shaft or the rotation of the second shaft is used to ensure the sequence of actuation of the shaft while maintaining the stability of the opening and closing of the electronic device.

The first mandrel 1 is fixed to the upper cover of the electronic device by a fixing portion, and the second mandrel 2 is fixed to the base of the electronic device by the fixing portion 2, and the concave portion 51 of the first-compression cam 5 is located The recess 61 of the upper first engaging cam 6 is also located at the upper end, the upper end of the pulley 7 abuts against the closing of the first cam 5, and the lower end is of the recess 61 of the second engaging cam 6. Therefore, the pulley 7 and the second rotating shaft 2 form a latch. When the upper cover is rotated and opened, as indicated by the arrow in Fig. 5, since the second rotating shaft 2 and the pulley 7 are locked and locked, they do not rotate relative to each other, and therefore, the first rotating shaft 1 is rotated to be opened. When the first mandrel 10 rotates, the first engaging cam $ rotates, and its circle is 8 M438797. The pulley 7 is held by the pulley 7 so that the pulley 7 is fitted to the second engaging cam 6. See Fig. 6, when the upper cover is opened 180 degrees clockwise, the first to the lower, the facing pulley 7 and the second engaging cam are as shown in Fig. 9-10, and the first stopping portion 1〇2 follows The first-to-heart rotation refers to the first-stage block 32 of the first web 3, and can no longer be rotated. Therefore, when the upper cover continues to be turned over, the seventh connecting shaft 3 and the second connecting piece 4 are driven by the second rotating shaft 2 with respect to the ?? m'. When the first mandrel 1〇, '第:^结★, and the second connecting piece 4 rotate together clockwise, the pulley 7 disposed at the first: and the second connecting piece 4 rotates with the second engaging convex second brain Moving, the pulley 7 is gradually turned out of the second engaging cam 6: the recess 51 of the first engaging cam 5 is moved by nr.
