Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Example 1:

referring to fig. 1 to 5, the present embodiment provides a latch safety mechanism, including: the lock comprises a lock catch, a lock tongue suitable for being inserted into the lock hole 1 and a lock tongue driving assembly suitable for driving the lock tongue into the lock hole 1.

In detail, firstly, the bolt comprises a body 2 which is rotatably matched and connected with the fixed seat, and a lock hook 53 which is connected with the body 2; the lock hole 1 may be a through hole structure or a concave groove structure, which is not absolutely limited in this embodiment, and the use requirement of this embodiment is met as long as the lock hook 53 can partially enter the lock hole 1 to realize the matching between the lock hole 1 and the lock hook 53.

Secondly, the lock tongue driving assembly of the embodiment comprises a fixed seat which is rotationally connected with the lock tongue, and a rotary driving unit which is suitable for driving the lock tongue to rotate around the fixed seat; namely, the locking tongue can be buckled and separated relative to the lock hole 1 through the rotation of the locking tongue relative to the fixed seat. When the bolt is inserted into the lock hole 1, the bolt and the lock catch form a buckling relation, and the lock catch safety mechanism is in a locking state; when the lock tongue leaves the lock hole 1, the lock tongue and the lock catch form a separation relation, and the lock catch safety mechanism is in an unlocking state.

Furthermore, the body 2 is rotatably connected with the fixed seat; and the latch hook 53 is adapted to be inserted into the latch hole 1. The latch hook 53 is a hook structure, so that the latch hook 53 is easily inserted into the latch hole 1.

More specifically, the fixing seat comprises a pair of bases 6 arranged oppositely, and a rotating shaft 7 fixed between the pair of bases 6; wherein the body 2 is coupled to the rotation shaft such that the body 2 is suitable for driving the locking hook 53 to rotate around the circumference of the rotation shaft 7. Here a pair of bases 6 may be attached by a base plate 8.

It should also be noted that in an alternative embodiment, the bolt further comprises a ball 9 coupled to the end of the body 2 remote from the shackle 53, where the ball 9 is rotatable relative to the body 2. Under the structure, for the whole lock tongue structure, from the total length formed by the lock hook 53, the body 2 and the ball 9, the rotating shaft 7 is connected with the middle position of the lock tongue in the length direction, so that the ball 9 moves in the direction far away from the lock hole 1 while the pushing block 13 applies the pushing action on the ball 9, and the lock hook 53 moves in the direction close to the lock hole 1 so as to be inserted into the lock hole 1 to realize the buckling locking of the lock hook 53 and the lock hole 1.

In addition, the rotary driving unit of the present embodiment includes a pushing block 13 located between the lock hole 1 and the lock tongue and adapted to push the ball 9, and a sliding seat 10 slidably connected to the pushing block 13, where the sliding seat 10 is connected to the bottom plate 8 to form an L-shaped structure, as shown in the attached drawings. A slide rail 11 is arranged on the slide seat 10, and a slide block 12 which is suitable for sliding along the slide rail 11 is matched and connected with the push block 13.

Wherein the end surface of the push block 13 facing the ball 9 is an inclined surface 131. Note that an end surface of the inclined surface 131 away from the balls 9 is convex with respect to an end surface of the inclined surface 131 close to the balls 9. With such a structure, during the linear movement of the pushing block 13, the inclined surface 131 exerts a pushing force on the ball 9 in the process of gradually approaching the ball 9, and during the pushing of the ball 9 by the pushing block 13, the ball 9 can rotate relative to the body 2, so that the friction resistance between the ball 9 and the pushing block 13 is reduced by the rotation of the ball 9. In other words, the ball 9 of the present embodiment is not an essential structure, but an optional implementation structure, and the ball 9 capable of rotating relative to the body 2 may not be disposed on the body 2, that is, the pushing block 13 can directly push the body 2, but the pushing resistance of the pushing block 13 is increased compared to the case where the ball 9 is disposed.

In summary, in the process of pushing the ball 9 of the latch bolt of the present embodiment, the pushing action on the ball 9 is gradually performed through the inclined surface 131 of the pushing block 13 and the ball 9, where the direction of the pushing action applied by the pushing block 13 on the ball 9 is to make the ball 9 move toward a side away from the lock hole 1, so that the latch bolt can rotate around the rotating shaft 7 under the pushing action of the ball 9, so that the locking hook 53 moves toward the lock hole 1 and gradually enters the lock hole 1, and finally the lock hole 1 and the latch bolt are fastened.

The rotary driving unit further comprises a linear motion power pair connected with the push block 13 and suitable for driving the push block 13 to slide along the sliding seat 10. For example, in an alternative implementation, the linear motion power pair includes a linkage block 15 connected to the push block 13, a nut 16 fixedly connected to the linkage block 15, and a screw 18 coupled to the nut 16; wherein the screw rod 18 is connected with a driving motor 19. That is, the push block 13 can slide linearly along the sliding seat 10 by the cooperation of the screw rod 18 and the screw nut 16.

When the push block 13 of the rotary driving unit of the present embodiment does not have a pushing action on the latch tongue, the latch tongue can be naturally separated from the lock hole 1, and the latch tongue driving assembly of the present embodiment further includes a spring body wound around the rotating shaft 7. The spring body of the specific embodiment comprises a main body part 41 which is abutted against the side end of the body 2 away from the lock hole 1, and a pair of winding parts 43 which are arranged on two sides of the main body part 41 and are wound on the reel 7; the ends of the pair of winding parts 43 far away from the main body part 41 are fixedly connected with the pair of bases 6 in a one-to-one correspondence mode. Thus, under the action of the spring body, when the pushing block 13 of the rotary driving unit has a pushing action on the bolt, the body part 41 is in a stretched state relative to the pair of winding parts 43; when the pushing action of the pushing block 13 of the rotation driving unit on the lock tongue is cancelled, the body 41 can drive the body 2 to leave from the lock hole 1 under the elastic recovery action of the body 41 relative to the pair of winding parts 43.

The specific implementation principle of the latch safety mechanism of the present embodiment is as follows:

when the tongue of the present embodiment is separated from the lock hole 1, the inclined surface 131 of the push block 13 is in contact with the ball 9 of the tongue, i.e., the push block 13 has no pushing action on the tongue.

When the locking hook 53 of the bolt and the locking hole 1 need to be locked, the driving motor 19 operates, the nut 16 drives the linkage block 15 to move axially along the screw rod 18, in the process, the linkage block 15 drives the push block 13 to move synchronously, so that the inclined surface 131 on the push block 13 is gradually contacted with the ball 9, and the inclined surface 131 of the whole body is inclined relative to the ball 9 instead of a flat end surface, so that the pushing acting force which can be generated by the push block 13 for the ball 9 is gradually increased, the ball 9 on the push block 13 moves towards the direction far away from the locking hole 1, and the locking hook 53 moves towards the direction close to the locking hole 1, so that the locking hook 53 and the locking hole 1 are locked finally.

When the lock hook 53 of the lock tongue needs to be separated from the lock hole 1 again, the motor 19 is driven by the movement, and the rotation direction of the motor at the moment is rotated with the rotation direction of the lock hook 53 when being buckled relative to the lock hole 1, so that the nut 16 can drive the push block 13 to gradually reset in the process of linear movement, the pushing force of the inclined surface 131 of the push block 13 on the ball 9 gradually disappears, the lock hook 53 can leave the lock hole 1, and the lock hook 53 can be unlocked relative to the lock hole 1.

To sum up, to the lock and the separation between the spring bolt of this embodiment and lockhole 1, only need realize through driving motor 19's operation, do not need extra auxiliary operation procedure, whole use is convenient high-efficient.
