the support shaft 3, the ratchet shaft 6 and the pawl shaft 12 are mounted on the upper bottom plate 2, the ratchet 1 and the ratchet spring 7 are mounted on the ratchet shaft 6, one end of the ratchet spring 7 is connected with the ratchet 1, the other end of the ratchet spring 7 is connected with the upper bottom plate 2, the pawl 13, the pawl spring 11 and the pawl shaft sleeve 10 are mounted on the pawl shaft 12, one end of the pawl spring 11 is connected with the pawl 13, the other end of the pawl spring 11 is connected with the lower bottom plate 14, the support rocker arm 8 is mounted on the pawl shaft sleeve 10, the support rocker arm spring 5 is mounted on the support rocker arm 8, and the other end of the support rocker arm spring 5 is connected with the lower bottom plate 14;
an upper bottom plate locking notch 2.1 is arranged on the upper bottom plate 2, a lower bottom plate locking notch 14.1 is arranged on the lower bottom plate 14, a first-gear ratchet wheel engaging hook 1.1, a second-gear ratchet wheel engaging hook 1.2, a ratchet wheel locking hook 1.3, a ratchet wheel locking finger 1.4 and a ratchet wheel locking bulge 1.5 are arranged on the ratchet wheel 1, a ratchet wheel locking notch 1.6 is arranged on the ratchet wheel 1 between the ratchet wheel locking hook 1.3 and the ratchet wheel locking finger 1.4, a ratchet locking surface 1.7 is arranged on the ratchet locking bulge 1.5, a ratchet locking finger 1.4 is positioned between a second-gear ratchet engaging hook 1.2 and a ratchet locking hook 1.3, the ratchet locking hook 1.3 is positioned between the ratchet locking finger 1.4 and the ratchet locking bulge 1.5, the second-gear ratchet engaging hook 1.2 is positioned between a first-gear ratchet engaging hook 1.1 and the ratchet locking finger 1.4, the ratchet locking bulge 1.5 is positioned between the first-gear ratchet engaging hook 1.1 and the ratchet locking hook 1.3, a pawl meshing hook 13.1 and a pawl locking bulge 13.2 are arranged on the pawl 13, and a pawl locking cambered surface 13.3 is arranged on the pawl locking bulge 13.2; the ratchet locking notch 1.6, the upper bottom plate locking notch 2.1 and the lower bottom plate locking notch 14.1 are matched to form a locking notch, the ratchet locking hook 1.3 is matched with the ratchet locking finger 1.4, the first-gear ratchet engaging hook 1.1 and the second-gear ratchet engaging hook 1.2 are matched with the pawl engaging hook 13.1, and the ratchet locking surface 1.7 is matched with the pawl locking cambered surface 13.3.
The cylindrical rubber pad 4 is arranged in the supporting rocker spring 5, so that the noise generated when the supporting rocker spring 5 extends and contracts can be reduced.
The ratchet spring 7 is sleeved on the pawl shaft sleeve 10.
A microswitch 9 is also arranged on the upper bottom plate 2; a microswitch triggering bulge 8.1 is also arranged on the supporting rocker arm 8, and the microswitch triggering bulge 8.1 is matched with the microswitch 9; when the supporting rocker arm 8 rotates around the pawl shaft 12, the micro switch trigger bulge 8.1 triggers the micro switch 9.
Fig. 2 shows the lock body in the fully locked state (i.e., the second gear), in which the second gear engaging hook 1.2 of the ratchet 1 is fully engaged with the pawl engaging hook 13.1 of the pawl 13, and the lid is closed.
The unlocking working principle of the double-drawer cover lock body is as follows: when the pawl 13 is pulled by the wire, the pawl 13 rotates anticlockwise around the pawl shaft 12, and the engagement amount of the pawl 13 with the ratchet 1 becomes smaller and smaller as the rotation angle of the pawl 13 increases (the ratchet 1 is subjected to clockwise torque under the action of the ratchet spring 7). Therefore, when the ratchet 1 and the pawl 13 are completely disengaged, the ratchet 1 rotates clockwise around the ratchet shaft 6. In order to realize the function, as shown in fig. 3, a ratchet locking surface 1.7 of the ratchet 1 is in contact with a pawl locking cambered surface 13.3 of a pawl 13 to form a locking structure. When the ratchet wheel 1 moves to the position, the ratchet wheel locking lug 1.5 of the ratchet wheel 1 collides with the pawl locking lug 13.2 of the pawl 13 to block the movement trend, and after the wire drawing tension is removed, the pawl 13 (which is provided with clockwise torque by the pawl spring 11) rotates clockwise. The deadlocking structure is released, the ratchet 1 returns to the meshing position under the action of the spring force of the ratchet spring 7 and the pawl 13 under the action of the spring force of the pawl spring 11, at the moment, the pawl meshing hook 13.1 is meshed with the first-gear ratchet meshing hook 1.1, and as shown in fig. 4, the lock body is in a half-locking (namely, first-gear) state at the moment. The above steps are repeated, and then the pawl 13 is pulled through the wire drawing, the ratchet 1 is opened to the maximum position, as shown in 5, at this time, the lock body is completely opened, and the whole unlocking process is finished.
