Detailed description of the invention

Quick connection lock of the present invention is determined and release mechanism, for realizing docking between component A with component B, comprises docking base 1, lock 2, dead bolt 3, stop column 4, bearing 5 and torsion spring 6, as shown in Figure 1.

Described docking base 1 is arranged on component A, has the structure of V-type groove, and V-type trench bottom, as lock room, is used for coordinating with lock 2.Make V-type groove along the fore-and-aft direction design of docking base 1, then, on docking base 1 front side wall, be positioned at V-type groove side and be installed with stop column 4 and bearing 5; Stop column 4 axis is with to dock base 1 leading flank vertical.

Described dead bolt 3 is sector structure, and docks base 1 leading flank and be arranged in parallel.Central angle place and the bearing 5 of dead bolt 3 are coupling by connecting axle, can rotate around bearing 5; Connecting axle axis docking base 1 leading flank is vertical.Dead bolt 3 has deep-slotted chip breaker 7 along fan-shaped arc direction, and makes stop column 4 be positioned at deep-slotted chip breaker 7.

Described torsion spring 6 is arranged on bearing 5, and torsion spring 6 one end is fixed on dead bolt 3, and the other end is fixed on docking base 1.Torsion spring 6 has certain pre-fastening moment, and without under External Force Acting, dead bolt 3 turns clockwise to stop column 4 around bearing 5 and contacts with deep-slotted chip breaker right-hand member under pre-fastening moment effect; Thus, by the effect of stop column 4, dead bolt 3 can only be rotated in limited angle around bearing 5.When dead bolt 3 is rotated counterclockwise, the moment that torsion spring 6 produces, namely the restoring moment of dead bolt 3 increases.

Described lock 2 and component B fix or hinged.When component A and component B is in the lock state, lock 2 is with to dock base 1 leading flank vertical, and be positioned at V-type bottom land end on docking base 1, stop column 4 contacts with deep-slotted chip breaker right-hand member on dead bolt 3, simultaneously, the arcwall face of lock 2 external surface and dead bolt 3 is tangent or there is certain interval, is limited in V-type groove by lock 2 by dead bolt 3, and then lock cannot move and maybe can only move very little distance and the state that cannot go out of lock.

In the locked state, torsion spring 6 still has pretightning force, and prevent dead bolt 3 to be rotated counterclockwise to unblock under gravity or the effect of microvariations power, cause lock 2 to skid off V-type groove, namely this pretightning force can avoid the false dismissal of lock-out state.In the present invention, V-type groove upper design is two sections of slopes, and upper semisection ramp slope is less than lower semisection ramp slope; And V-type trench bottom is designed to arc transition, arc radius is equal with lock 2 section radius, and then prevents from locking the wearing and tearing in releasing process between V-type groove and lock 2.

By said structure, component A and component B enters line-locked process, is completed by following step:

A, lock 2 are moved down by the cell wall of direction on V-type groove along V-type groove under latching force effect, contact, as shown in Figure 2 a with dead bolt 3;

B, latching force continuingly act on lock 2, and drive dead bolt 3 to be rotated counterclockwise, torsion spring 6 can produce clockwise restoring moment simultaneously.The moment that active force between lock 2 and dead bolt 3 produces overcomes torsion spring 6 moment, dead bolt 3 is rotated counterclockwise, until when the distance of lock 2 and dead bolt 3 contact point and V-type groove edge is not less than the diameter of lock 2, lock 2 slips into the lock room of V-type groove under the latching force effect continued, as shown in Figure 2 b;

C, due to now between lock 2 and dead bolt 3 without active force, the restoring moment clockwise under influence that dead bolt 3 provides at torsion spring 6 rotates, as shown in Figure 2 c;

Under d, the restoring moment effect that provides at torsion spring 6, stop column 4 finally contacts with the deep-slotted chip breaker right-hand member on dead bolt 3, is closed the lock room of V-type groove or semiclosed, enters lock-out state, as shown in Figure 2 d between component A and component B.

Component A and component B carries out the process unlocked, and is completed by following step:

A, under the effect of releasing force F1, make dead bolt 3 overcome torsion spring 6 moment, rotate counterclockwise, as shown in Figure 3 a;

B, under the continuous action of releasing force F1, stop column 4 contacts with dead bolt 3 deep-slotted chip breaker left end, is opened the lock room of V-type groove, as shown in Figure 3 b;

C, lock, under the effect of releasing force F2, move upward, leave lock room; In this process, releasing force F1 throws away and continuingly acts on dead bolt 3, as shown in Figure 3 c;

The releasing force F1 that D, releasing act on dead bolt 3, dead bolt 3 rotates at the restoring moment clockwise under influence that torsion spring 6 provides and contacts with dead bolt 3 deep-slotted chip breaker right-hand member to stop column 4, and dead bolt 3 cannot continue to rotate, and component A and component B completes unblock.
