Description

Description A trigger mechanism for automatically popping up a main body of a lock body

The invention belongs to the technical field of door lock manufacturing, and relates to a lock body structure, in particular to a trigger mechanism capable of automatically popping a main body of a lock body.

Background technique

At present, the door lock on the market, the action mechanism of the trigger mechanism automatically popping up the main body of the lock body is as follows: When the trigger tongue hits the door edge strip, the main tongue starts to pop up, and then the door continues to rotate until the main tongue is inserted into the door edge strip Opening. The disadvantage of this structure is that the main tongue has been ejected in advance at the opening that does not reach the edge strip, which will cause collision and friction between the main tongue and the door edge strip, and generate a large sound when closing the door, and the door edge strip The beauty of the film produces film, which will seriously damage the edge of the door.

Therefore, it is necessary to design a new trigger mechanism to overcome the drawback of the timely and accurate ejection of the main tongue at the opening of the door edge strip. Summary of the invention

The invention discloses a trigger mechanism for realizing the automatic pop-up of the main body of the lock body, which solves the above technical problem, and triggers the tongue to be ejected at the exact position of the opening of the door edge strip, thereby triggering the main tongue to pop up, and can realize Channel lock function.

In order to achieve the above object, the technical solution adopted by the present invention is as follows: A trigger mechanism for automatically popping the main body of the lock body, including a main lock tongue, a first pick, a first column, a torsion spring, and a second pick , two-way tongue connecting plate, second column, second torsion spring, two-way tongue, three-column column, four-column column, side bar, five-column column, six-column column, spring, spring seat and anti-locking plate, riveting on the first column In the housing, the first pick-up piece is mounted on the first column, and a torsion spring is also mounted on the first column. One end of the torsion spring is placed in the first piece of the hole, and the other end of the torsion spring is pressed. The side strip is provided with a No. 1 gasket and a No. 1 open retaining ring on the No. 1 column; the No. 5 column and the No. 6 column are riveted on the casing, and riveted on the two-way tongue connecting plate There are four pillars and three pillars. The second pillar is riveted on the second pick. The second pick and the second torsion spring are installed on the fourth and third pillars, and then the mat is installed on the fourth pillar. Sheet and open retaining ring limit; Two-way tongue is installed in the two-way tongue connecting plate, and is installed with the spring in the fifth column and the sixth column, the two-way tongue extends out of the side hole hole, and then the fifth No. 5 gasket, the fifth opening Retaining ring and No. 6 gasket, No. 6 opening retaining ring.

The invention realizes the trigger mechanism for automatically popping out the main tongue of the lock body, and only triggers the main tongue to pop up when the trigger tongue is popped at the correct position at the opening of the door edge strip, and the channel lock function can be realized, and the realization of the automatic pop-up function mechanism is not realized. Affected by the size of the gate gap. It changes the triggering mechanism form that the main body of the lock body automatically pops up, and solves the problem that the main tongue is ejected in advance after the trigger tongue hits the door edge strip, making the trigger structure accurate, simple, safe, reliable, and changing the past. The main tongue automatically pops up and easily hits the edge of the door frame to cause damage, so that the electronic lock field has a more perfect matching lock body. DRAWINGS

The present invention will be further described below by way of embodiments with reference to the accompanying drawings.

As shown in FIG. 1 , the trigger mechanism of the main body of the lock body automatically pops up in this embodiment, including the main lock tongue plate 1 , the first picking piece 2 , the first column 5 , the first torsion spring 6 , and the second dial Sheet 7, two-way tongue connecting plate 8, two-column column 9, two-ring torsion spring 11, two-way tongue 12, three-column column 13, four-column column 15, side strip 16, five-column column 18, six-column column 21, spring 23 The spring seat 24, the anti-locking plate 26, the first column 5 are riveted in the casing 25, and the first pick 2 is mounted on the first column 5 and can be rotated around the first column 5; A torsion spring 6 is installed, and one end of the torsion spring 6 is placed in the hole of the first picking piece 2, and the other end of the torsion spring 6 is pressed against the side strip 16; a spacer is also mounted on the first column 5 4 and the first opening ring 3. A fifth column 18 and a sixth column 21 are riveted on the casing 25, and a four-column column 15 and a third column 13 are riveted on the two-way tongue connecting plate 8, and a second column 9 is riveted on the second paddle 7 The second pick 7 and the second torsion spring 11 are mounted on the fourth column 15 and the third column 13, and the second pick 7 can be rotated; and the spacer 10 and the open retaining ring 14 are mounted on the fourth column 15 The two-way tongue 12 is mounted on the front end of the two-way tongue connecting plate 8, and is mounted in the fifth column 18 and the sixth column 21 together with the spring 23, and the other end of the spring 23 is mounted on the spring seat 24. The two-way tongue 12 protrudes from the side strip 16 hole, and then the fifth No. 19, the fifth opening ring 17 and the sixth No. 22, and the sixth opening ring 20 are installed.

The door opening state is as shown in Fig. 1. The steps of automatically opening the main body of the lock body are as follows: Step 1. When the door is closed, the two-way tongue 12 hits the door edge strip 16, forcing the two-way tongue 12 to retract inside the lock body, prompting the two-way tongue connection. The plate 8 compresses the spring 23. Step 2, as shown in FIG. 2, in the process of retracting the two-way tongue 12, after the second pick 7 is in contact with the first pick 2, the second pick 7 is forced to swing under the blocking action of the first pick 2 . As shown in Fig. 3, when the second pick 7 is swung to the maximum limit position of the first pick 2, it is separated from the blocking of the first pick 2, and the second pick 7 is forced to swing back to the second through the second torsion spring 11. The reset state shown in Figure 4. Step 3, when the two-way tongue 12 and the main tongue plate 1 move to the corresponding through hole of the door edge strip 16, by the force of the compressed spring 23, as shown in FIG. 5, the two-way tongue 12 is ejected, When the second pick 7 pushes the first pick 2, the first pick 2 is rotated and unlocked from the main latch 1 and then passed through the compressed torsion spring. The force of 27 causes the main locking tongue 1 to be ejected, so that the locking tongue of the main locking tongue 1 accurately protrudes into the corresponding through hole of the side strip 16, and is in a locked state, as shown in FIG. Steps of implementing the channel lock function: As shown in FIG. 7, the anti-locking plate 26 is fastened into the main locking tongue plate 1 so that the main locking tongue plate 1 cannot be ejected, forcing the door to open and close the door state, and the lock body only realizes the above-mentioned lock body. The tongue lock 1 automatically pops up in steps 1 and 2 of the state.
