It should be noted that the connecting rod 9 and the first tongue locking piece 1 may also be an integral structure.

As shown in fig. 11, fig. 11 is a schematic view of an internal structure of a lock cylinder with a housing on one side removed, a limiting structure of an installation seat 4 is arranged in the lock cylinder, so that the installation seat 4 cannot move to the left, the return spring 3 is in a compressed state, the right end of the first bolt 1 is exposed out of the lock cylinder body 8, and the first bolt 1 maintains the state under the elastic force of the return spring 3. It should be noted that the first tongue 1 is not completely exposed outside the lock cylinder body 8.

The advantage that sets up like this utilizes reset spring 3 cooperation first lock tongue 1 has realized the reset function of first lock tongue 1, through the reset function cooperation of first lock tongue 1 the locking subassembly has realized unblanking and shutting of lock core.

Optionally, as shown in fig. 11, the latch bolt assembly includes: and the sealing ring 11 is sleeved on the surface of the first tongue locking part 1. Here, the first tongue locking piece 1 is a columnar structure with a diameter that is not completely equal, and the sealing ring 11 is sleeved on the circumferential surface of the first tongue locking piece 1. Of course, the locking tongue may have other shapes. The isolation of the interior of the lock cylinder from the external environment is realized through the arrangement of the sealing ring 11. Preferably, the circumferential surface of the first tongue locking part 1 is provided with an annular groove, and the sealing ring 11 is arranged in the annular groove.

Here, one end of the first tongue 1 is connected to the connecting rod 9, the other end of the first tongue 1 is exposed out of the key cylinder body 8, and one end of the first tongue 1 exposed out of the key cylinder body 8 is an arc-shaped head 32. Here, the arcuate head 32 is hemispherical.

Preferably, as shown in fig. 5, the second tongue 29 is a cylindrical structure, the end surface 30 of the second tongue 29 axially far away from the connecting spring 33 is an arc surface or an inclined surface, the inclined surface or a tangent plane of the arc surface is inclined toward the pressing direction, and the pressing direction is a direction in which the flip cover 15 moves when the flip cover 15 is pressed (i.e., when the flip cover is closed). Here, the axis of the cylindrical structure coincides with the center line of the spring. That is, when the flip cap 15 is pressed, the end surface 30 interacts with the curved head 32 of the first tongue 1. When the flap 15 is lifted, the cylindrical surface 31 of the second locking tongue 29 interacts with the curved head 32 of the first locking tongue 1. By adopting the design of the matching end surface or the inclined surface of the cylindrical surface 31, the transition is smoother when the first lock tongue 1 and the second lock tongue 29 act.

As shown in fig. 3 to 5, when the flip cover 15 is pressed, the first tongue locking piece 1 and the second tongue locking piece 29 act, the second tongue locking piece 29 presses the arc-shaped head 32 of the first tongue locking piece 1, and at this time, the moving directions of the first tongue locking piece 1 and the second tongue locking piece 29 are divided into two cases: the first tongue locking piece 1 is locked, and the first tongue locking piece 1 is unlocked. In the first situation, since the first tongue 1 is locked, the end surface of the second tongue 29 acts on the first tongue 1, the second tongue 29 moves in the direction of the connecting spring 33, and the flip cover 15 is continuously pressed to close the lock. In the second case, the end surface of the second tongue locking piece 29 acts on the first tongue locking piece 1, the first tongue locking piece 1 moves toward the return spring 3, the second tongue locking piece 29 may also move toward the direction of the connecting spring 33, and the flip cover 15 is continuously pressed to close the lock. The connection spring 33 itself has a certain rigidity and can prevent the connection spring 33 from bending greatly against the pressure at the time of pressing.

When the flip cover 15 is lifted, the cylindrical surface 31 of the second lock tongue 29 presses the arc-shaped head of the first lock tongue 1, and the first lock tongue 1 moves towards the direction of the return spring 3, and the flip cover 15 is continuously lifted to realize unlocking.

The advantage of this arrangement is that even if the first tongue is locked, the flip cover can still be buckled and still can be locked. In addition, through the setting of second lock tongue 29, work as the lock or lift up during flip 15, first lock tongue 1 with second lock tongue 29 all takes place the effect, and the smooth and easy degree of spring bolt motion when having increased the shutting has avoided the card that causes when single spring bolt effect to die or the phenomenon of not smooth and easy to take place. Meanwhile, the second bolt assembly has certain flexibility through the arrangement of the connecting spring 33, and the damage to the lock body during unlocking and locking is reduced.

Example four

During shutting, when flip 15 lock back, first tongue 1 with the second tongue is spacing each other, but this moment first tongue 1 is not locked, when lifting up flip 15, first tongue 1 still can to lock core body 8 inside motion. At this moment, after the flip 15 is buckled, the locking component locks the first tongue locking part 1, and limits the first tongue locking part 1, so that the first tongue locking part 1 and the second tongue locking part 29 are kept in a limiting state. When the lock needs to be unlocked, the first lock tongue 1 is released from the limiting position through the locking component, the flip cover 15 is lifted at the moment, and the first lock tongue 1 can move towards the inside of the lock cylinder body 8. The advantage of this setting is that, through the setting of the locking assembly, locking the first tongue 1 can effectively prevent the situation that the flip lid is opened or closed easily, and when the locking assembly locks the first tongue 1, the flip lid cannot be opened or closed. The flip cover can be opened or closed only when the locking member releases the lock of the first locking tongue 1.

EXAMPLE five
