working principle

When the application is from the initial state (Fig. 2) to the open state (Fig. 3), after the mobile power supply is loaded into the battery compartment 1, the battery compartment 1 simultaneously squeezes the left rotation fastener 9 and the right rotation fastener 4, while the left rotation fastener 9. The right rotary fastener 4 compresses the compression spring 2. Since the end of the left rotary fastener 9 is provided with an interlocking track slot 91, and the end of the right rotary fastener 4 is provided with an interlocking limit post 41, the specific operation It is: when the mobile power supply is under unbalanced force or is installed at an angle, and the left rotating fastener 9 or the right rotating fastener 4 on one side is first squeezed out, the linkage limit post 41 will be driven in the linkage track slot through the linkage structure. 91, and when the opening angle of the left rotating fastener 9 or the right rotating fastener 4 acts on the interlocking structure through the center of the rotating shaft, it is transformed into a downwardly inclined force. When one side moves downwards, the interlocking track slot 91 The fixed linkage limit post 41 will move downward together, so that the left rotation fastener 9 and the right rotation fastener 4 are opened at the same angle through the center of the rotating shaft, thereby driving the rotation fastener on the other side to open;

When the application is from the open state (Fig. 3) to the initial state (Fig. 2), under the continuous action, only when the left rotating fastener 9 and the right rotating fastener 4 are simultaneously contracted by the force of the compression spring 2, the lock can be locked. Success, specifically: when the mobile power supply is inserted obliquely due to the matching gap, and the locking groove on one side reaches the buckled position first, the rotating fastener on the other side is in the open state, and the interlocking structure (the interlocking limit post 41 is interlocking) The movement in the orbital groove 91) will restrict the closing of the rotary fastener on this side at this time. When one side of the interlocking limit post 41 or the interlocking orbital groove 91 does not move, the other side will be restricted and remain motionless. The lock will be unsuccessful, so as to avoid the situation of unilateral buckle. Only by continuing to press down on the mobile power supply, the lock can be successfully locked when the rotating fasteners on both sides can move at the same time, as shown in Figure 3.
