Detailed Description

In order to make the creation features, technical means and achievement objects of the present invention easily understood and appreciated, the present invention will be further described with reference to the following embodiments.

As shown in fig. 1, the utility model provides a pair of two-way tongue fixing device, including triggering tongue device 1, triggering plectrum 2, two-way tongue device 3, two-way tongue stopping group 4, two-way tongue torsional spring 5, two-way tongue stopping group extension spring 6 and trigger tongue pressure spring 7, trigger tongue device 1 and trigger plectrum 2 detachable contact, trigger plectrum 2 and two-way tongue stopping group 4 detachable contact, two-way tongue device 3 is connected with two-way tongue torsional spring 5, two-way tongue stopping group 4 is connected with two-way tongue stopping group extension spring 6, trigger tongue pressure spring 7 cover is established on triggering tongue device 1.

It should be noted that the embodiment of the present invention, "separable contact" means that the component a and the component B are separable and do not contact when not receiving external pressure, and when receiving external pressure, the component a and the component B may generate an interaction force after contacting.

Specifically, the embodiment of the utility model provides a trigger tongue device 1 includes extension 111, card strip 112 and long arm 113, card strip 112 and trigger plectrum 2 detachable contact, trigger tongue pressure spring 7 cover is established on long arm 113.

Preferably, the embodiment of the present invention provides a trigger plectrum 2 including mounting 21, left end 22 and right end 23, trigger plectrum 2 and pass through mounting 21 to be fixed inside the lock shell, left end 22 and card strip 112 detachable contact, right end 23 and two-way tongue stopping group 4 detachable contact.

The bidirectional tongue-and-groove device 3 of the embodiment of the present invention includes a tongue-and-groove portion 31 and an inner end portion 32. The bidirectional sliding tongue retaining group 4 comprises a central shaft 41 and a blocking piece 42, the bidirectional sliding tongue retaining group 4 is fixed inside the lock shell through the central shaft 41, and the blocking piece 42 is in separable contact with the right end part 23 of the trigger shifting piece 2.

Preferably, as shown in fig. 2, in order to realize the two-way sliding tongue lock door, in the direction parallel to the movement of the strike plate 17, the minimum distance L1 between the trigger tongue device 1 and the edge of the lock case is greater than the minimum distance L2 between the two-way sliding tongue device 3 and the edge of the lock case. Optionally, the embodiment of the present invention provides an inclination angle of the bidirectional tongue device 3 is larger than the inclination angle of the trigger tongue device 1 in the direction parallel to the movement of the latch plate 17, so that the bidirectional tongue device 3 can contact the latch plate 17 before the trigger tongue device 1.

It should be noted that the triggering tongue device 1 and the bidirectional sliding tongue device 3 are not limited to the above-mentioned setting mode, and other setting modes that can make the bidirectional sliding tongue device 3 contact the latch plate 17 before the triggering tongue device 1 are all applicable to the embodiment of the present invention.

In implementation, when the door is in an open state, the extension part 111 of the trigger tongue device 1 and the tongue sliding part 31 of the bidirectional tongue sliding device 3 both naturally extend out of the lock case, the trigger tongue device 1 pushes the left end part 22 of the trigger shifting piece 2 upwards through the pushing of the trigger tongue pressure spring 7, the clamping strip 112 abuts against the left end part 22 of the trigger shifting piece 2, the right end part 23 of the trigger shifting piece 2 pushes the blocking piece 42 of the bidirectional tongue sliding stopping group 4 downwards, the downward movement of the blocking piece 42 drives the bidirectional tongue stopping group 4 to shift leftwards, and the front end part 44 of the bidirectional tongue stopping group 4 is staggered with the inner end part 32 of the bidirectional tongue sliding device 3 and does not abut against any more. At this time, the bidirectional sliding tongue device 3 can be retracted into the lock case after receiving external pressure, and can be ejected out of the lock case due to the restoring action of the bidirectional sliding tongue torsion spring 5 connected thereto after no external pressure.

When the door is closed, the bidirectional sliding tongue device 3 contacts the lock catch plate 17 before the trigger tongue device 1, the sliding tongue part 31 starts to be recovered after the bidirectional sliding tongue device 3 contacts the lock catch plate 17, at the moment, the inner end part 32 of the bidirectional sliding tongue device 3 moves downwards, the front end part 44 of the bidirectional sliding tongue retaining group 4 is pushed open leftwards, the sliding tongue part 31 is gradually recovered into the shell, and when the bidirectional sliding tongue device 3 reaches the groove structure 171 corresponding to the lock catch plate 17 and the bidirectional sliding tongue device 3, the bidirectional sliding tongue device 3 is reset and popped out under the action of the bidirectional sliding tongue torsion spring 5. Meanwhile, after the trigger tongue device 1 contacts the lock catch plate 17 after the bidirectional sliding tongue device 3, the extending part 111 is gradually recovered into the lock case until the extending part is completely pressed, in the process, the trigger tongue pressure spring 7 is pressed, the clamping strip 112 moves downwards and does not abut against the left end part 22 of the trigger shifting piece 2 any more, the left end part 22 of the trigger shifting piece 2 moves downwards freely, the right end part 23 moves upwards freely, the blocking piece 42 of the bidirectional sliding tongue backstop group 4 is not pushed any more, the front end part 44 of the bidirectional sliding tongue backstop group 4 moves rightwards under the reset action of the bidirectional sliding tongue backstop group tension spring 6 and abuts against the inner abutting end 31 of the bidirectional sliding tongue device 3, so that the inner abutting end 31 cannot continue to recover into the lock case, and the sliding tongue part 31 of the bidirectional sliding tongue device 3 extends out of the lock case and is fixed, and the bidirectional sliding lock door is completed.

To sum up, the embodiment of the utility model provides a two-way sliding tongue device 3 is earlier than triggering tongue device 1 contact hasp board 17, is triggering tongue device 1 and is pushed down the back completely, and two-way sliding tongue device 3 pops out and is fixed, can't withdraw the lock shell, realizes two-way sliding tongue lock door, plays theftproof, protection safety's effect simultaneously.
