[0024] In order to deepen the understanding of the utility model, the utility model will be further described below in conjunction with examples, which are only used to explain the utility model and do not constitute the limitation of the protection scope of the utility model.

[0025] As Figures 1-2 shown, the embodiment provides a kind of multiple input and output door lock mechanism, including card plate 1, connecting rod 2, pawl 3 and gear 4, pawl 3 is arranged in card plate 1 side, gear 4 is arranged above pawl 3, it is characterized in that: mechanism is also provided with first rotation axis 5, first rotation axis 5 is provided with first release lever 6, connecting rod 2 is arranged in the upper end of first release lever 6, first release lever 6 is opened with first opening 7 and second opening 8, first opening 7 and second opening 8 are arranged at two positions on first release lever 6 respectively.Pawl 3 is provided with second release lever 9, one end of second release lever 9 is provided with second rotation axis 10, the other end of second release lever 9 is provided with third opening 11.Second rotation axis 10 is also provided with third release lever 12, third release lever 12 is connected with gear 4 and is in contact, gear 4 is rotated and is in contact with third release lever 12 by third rotation axis 13.Card plate 1 is provided with fourth rotation axis 14, fourth rotation axis 14 is provided with fourth release lever 15.Card plate 1 is provided with fifth rotation axis 16, and card plate 1 rotates with fifth rotation axis 16 as the axis.

[0026] AsFigure 6 As shown, the connecting rod 2 is provided with a hook-shaped feature 17, and the first release rod 6 is further provided with a first auxiliary release rod 18.

[0027] As shown, the connecting rod 2 is provided with a hook-shaped feature 17, and the first release rod 6 is further provided with a first auxiliary release rod 18. Figure 7 As shown, the connecting rod 2 is provided with a hook-shaped feature 17, and the first release rod 6 is further provided with a first auxiliary release rod 18.

[0028] As shown, the connecting rod 2 is provided with a hook-shaped feature 17, and the first release rod 6 is further provided with a first auxiliary release rod 18. Figures 8-9 As shown, the second release rod 9 is provided with a second auxiliary release rod 21. The gear 4 is provided with a cam structure 22, and the third release rod 12 is provided with a third release rod first auxiliary rod 23 at one end close to the gear 4, a third release rod second auxiliary rod 24 at one end away from the gear 4, and a third release rod third auxiliary rod 25 on one side of the second auxiliary release rod 21 of the coaxial second release rod 9.

[0029] Each rotating shaft is provided with a reset spring, so that it can be kept or returned to the initial position after action.

[0030] As shown, the first release state works as follows: Figure 3

[0031] The first release rod 6 is provided with a second opening 8, and a pull line can be applied. Force is applied in the direction of the arrow, and the first release rod 6 rotates around the first rotating shaft 5 in the direction of the arrow. The first opening 7 on the first release rod 6 also moves, and the first opening 7 can be fitted with a pull line to produce displacement.

[0032] The first release rod 6 has a special-shaped hole 20, which cooperates with the special-shaped shaft hole 19 on the connecting rod 2. When the first release rod 6 rotates in the direction of the arrow, it also drives the connecting rod 2 to move. The hook-shaped feature 17 on the connecting rod 2 hooks the fourth release rod 15 to rotate around the fourth rotating shaft 14. The fourth release rod 15 is coaxial with the pawl 3 and is hard connected, driving the pawl 3 to rotate in the release direction and making it disengage from the clamping plate 1. After the clamping plate 1 disengages from the pawl 3, it can be opened.

[0033] As shown, the second release state works as follows: Figure 4

[0034] ​​The second release rod 9 has a third opening 11 for applying a pull wire. When force is applied in the direction of the arrow, the second release rod 9 rotates around the second pivot 10 in the direction of the arrow. The second auxiliary release rod 21 on the second release rod 9 abuts against the third release rod 12 and the third auxiliary rod 25. The second release rod 9 and the third release rod 12 are coaxial. The second release rod 9 pushes the third release rod 12 to rotate in the direction shown by the arrow. The second auxiliary rod 24 of the third release rod abuts against the first auxiliary release rod 18, which in turn pushes the first release rod 6 to rotate around the first pivot 5. The first opening 7 on the first release rod 6 also moves accordingly. A pull wire can be installed on the first opening 7 to cause displacement.

[0035] The first release rod 6 has a special-shaped hole 20, which mates with the special-shaped shaft 19 hole on the connecting rod 2. When the first release rod 6 rotates in accordance with the arrow, it simultaneously drives the connecting rod 2 to move. The hook-shaped feature 17 on the connecting rod 2 hooks the fourth release rod 15, causing it to rotate around the fourth rotating shaft 14. The fourth release rod 15 is coaxial with the pawl 3 and rigidly connected, causing the pawl 3 to rotate in the release direction, thus disengaging it from the locking plate 1. After the locking plate 1 disengages from the pawl 3, it can be opened.

[0036] like Figure 5 As shown, the working principle of the third release state is as follows:

[0037] Gear 4 can be externally powered to rotate in the direction of the arrow. The cam feature 22 on gear 4 abuts against the first auxiliary rod 23 of the third release rod. The first auxiliary rod 23 of the third release rod causes the third release rod 12 to rotate around the second rotating shaft 10 in the direction of the arrow. The second auxiliary rod 24 of the third release rod abuts against the first auxiliary release rod 18, thereby pushing the first release rod 6 to rotate around the first rotating shaft 5.

[0038] The first opening 7 on the first release rod 6 also moves accordingly. A pull wire can be installed on the first opening 7 to make it displaced. The first release rod 6 has a special-shaped hole 20, which cooperates with the special-shaped shaft 19 shaft hole on the connecting rod 2. When the first release rod 6 rotates according to the arrow, it drives the connecting rod 2 to move at the same time. The hook-shaped feature 17 on the connecting rod 2 hooks the fourth release rod 15 to make it rotate around the fourth rotating shaft 14. The fourth release rod 15 is coaxial with the pawl 3 and rigidly connected, which drives the pawl 3 to rotate in the release direction to disengage from the locking plate 1. After the locking plate 1 disengages from the pawl 3, it can be opened.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
