Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

Example 1

As shown in fig. 1 to 3, the present embodiment provides a locking mechanism, which includes a locking device 1, a locking member 2 and a control member 3, wherein the locking device 1 is used for locking a box 4/box cover 5 of an external case, the control member 3 is used for driving the locking member 2 to approach or leave the box cover 5, the locking member 2 is rotatably disposed on the box 4/box cover 5 of the external case, and the locking member 2 is engaged with the control member 3 to lock the control member 3.

When needs pinning, drive retaining member 2 through control piece 3 and remove and make retaining member 2 can pin box 4 and case lid 5 through the mode of detaining, realize pinning to control piece 3 by the mode of retaining member 2 and the meshing of control piece 3 again afterwards, can let hasp 1 no longer rotate or round trip movement. When needs unblock, only need to part retaining member 2 and control 3, can let control 3 retreat and drive hasp 1 and retreat, reached and let box 4 and the separable effect of case lid 5.

In this embodiment, the control member 3 includes a rotating shaft 31 and a gear 32, the rotating shaft 31 is rotatably disposed on the box 4/box cover 5 of the external case, the gear 32 and the latch 1 are both mounted on the rotating shaft 31, and the locking member 2 has a tooth 21 for engaging with the gear 32.

That is, the rotating shaft 31 can move back and forth relative to the box body 4/box cover 5, so as to drive the lock catch 1 and the gear 32 to move back and forth together, after the lock catch 1 is locked on the box body 4/box cover 5, the gear 32 is just located on the stroke of the locking member 2, then the locking member 2 can be meshed with the gear 32, and the locking action on the rotating shaft 31 is realized through a meshing mode.

Specifically, one end of the locking member 2 is provided with an arc-shaped portion 22 which is adapted to the shape of the gear 32, and the tooth 21 is arranged on the arc-shaped portion 22; the other end of retaining member 2 is equipped with jack 23, and jack 23 activity is provided with screw 24, and screw 24 spiro union is in the box 4 of external quick-witted case lid 5, and retaining member 2 uses screw 24 to rotate as the axle.

When the locking member 2 rotates, the arc portion 22 rotates along with the gear until the arc portion 22 covers the gear 32, so that a plurality of meshes are meshed with the gear 32, and the locking effect is better.
