DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1-6 As shown, a double-person double-control door opening locking mechanism of the present invention includes two door bodies 1, and the outer side walls of the door bodies 1 are fixedly connected with a locking mechanism, and the locking mechanism includes a locking block 4 fixedly connected to the two door bodies 1, and the outer side wall of one of the door bodies 1 is rotatably connected to an interlocking block 5 through a pin shaft, and the top of the interlocking block 5 is rotatably connected to a second connecting rod 7 through a rotating shaft, and one end of the second connecting rod 7 is inserted in the locking block 4; a first connecting rod 6 is provided below the second connecting rod 7, and the first connecting rod 6 is rotatably connected to the interlocking block 5 through a rotating shaft, and one end of the first connecting rod 6 is inserted in the other locking block 4, and a second speed sensor 9 is fixedly connected to the bottom of the rotating shaft of the second connecting rod 7; a first speed sensor 8 is fixedly connected to the bottom of the rotating shaft of the first connecting rod 6; the outer side wall of the interlocking block 5 is fixedly connected to a motor 26, and the motor 26 is electrically connected to the second speed sensor 9 and the first speed sensor 8.

[0029] During work, when the door needs to be opened, two people operate a locking block 4 respectively, unlock it through the locking block 4, and take out the second connecting rod 7. At the same time, another person operates another locking block 4, unlocks it through the locking block 4, and takes out the first connecting rod 6. The bottom of the second connecting rod 7 and the first connecting rod 6 are respectively provided with a second speed sensor 9 and a first speed sensor 8. If the second connecting rod 7 and the first connecting rod 6 are taken out at the same time, the speed of the second speed sensor 9 and the first speed sensor 8 will change at the same time. By transmitting the signal to the computer program, the computer program controls the motor 26. The motor 26 rotates to release the fixation of the horizontal plate 25, and the interlocking block 5 can be rotated. The interlocking block 5 rotates 90° to expose the pin 16 and the lock 18. Then the key is used to unlock the lock 18. Closing the door can be completed by the reverse operation of opening the door.

[0030] Further, such as Figure 3 As shown, a cavity 14 is provided in the locking block 4, and an insertion rod 10 is slidably connected in the cavity 14. One end of the insertion rod 10 is fixedly connected to a first spring 13, and one end of the first spring 13 is fixedly connected to the inner wall of the cavity 14. The second connecting rod 7 and the first connecting rod 6 are respectively matched with the insertion rod 10; the top of the insertion rod 10 is fixedly connected to a push rod 12, and the push rod 12 moves on the locking block 4.

[0031] During operation, when the locking block 4 is fixed, when the second connecting rod 7 rotates downward and contacts the insertion rod 10, the insertion rod 10 is squeezed inward under the pressure of the second connecting rod 7, and the first spring 13 is compressed until the second connecting rod 7 rotates to the bottom of the insertion rod 10. Under the action of the first spring 13, the insertion rod 10 is quickly reset to jam the second connecting rod 7; when the second connecting rod 7 needs to be removed, the push rod 12 is moved to drive the insertion rod 10 to move. When the insertion rod 10 moves, the first spring 13 is compressed, the insertion rod 10 contracts, and the second connecting rod 7 is rotated upward to take out the second connecting rod 7; the removal operation of the first connecting rod 6 is the same as the removal operation of the second connecting rod 7.

[0032] Further, such as Figure 1 and Figure 4 As shown, three fixing blocks 15 are fixedly connected to the two door bodies 1 in sequence, and a pin 16 is inserted into the three fixing blocks 15. The bottom of the pin 16 is fixedly connected to the first connecting block 2317. A second connecting block 2319 is fixedly connected to the door body 1, and the first connecting block 2317 cooperates with the second connecting block 2319; a lock 18 is provided on the second connecting block 2319.

[0033] During operation, when locking, the first connecting rod 27 is inserted into the second connecting block 2319 and the lock 18 is locked to complete the locking; when opening the door, the lock 18 is opened by the key, the first connecting block 2317 is rotated upward to leave the second connecting rod 27, and the first connecting block 2317 is driven to move the pin 16 toward the fixed block 15 on one side, and the other end of the pin 16 leaves the fixed block 15 at the edge, and the door can be opened.

[0034] Further, such as Figure 6 As shown, both ends of the interlocking block 5 are slidably connected to a moving plate 20 , and a connecting rod 27 is fixed to the top of the two moving plates 20 .

[0035] During operation, after the second connecting rod 7 and the second connecting rod 27 are opened at the same time, the motor 26 can be turned on, and the fixation of the movable plate 20 can be released by the motor 26. Then, by pulling the connecting rod 27 outward, the connecting rod 27 drives the movable plate 20 to move outward. The movable plate 20 no longer blocks the interlocking block 5, and the interlocking block 5 can be rotated to unlock.

[0036] Further, such as Figure 5 As shown, the output shaft of the motor 26 is rotatably connected to the interlocking block 5 through a bearing, and the output shaft of the motor 26 is fixedly connected to an elliptical block 24. Both sides of the elliptical block 24 are provided with a horizontal plate 25, and the side walls of the horizontal plate 25 are fixedly connected with three clamping columns 21, and the clamping columns 21 slide on the interlocking block 5, and one side of the clamping columns 21 is in contact with the movable plate 20; two connecting blocks 23 are fixedly connected to the inner wall of the interlocking block 5, and both sides of the connecting block 23 are fixedly connected to a second spring 22, and one end of the second spring 22 is fixedly connected to the horizontal plate 25.

[0037] During operation, in order to quickly release the fixation of the movable plate 20, the motor 26 is turned on, and the output shaft of the motor 26 drives the elliptical block 24 to rotate. The rotation of the elliptical block 24 releases the squeezing of the horizontal plate 25. Under the action of the second spring 22, the horizontal plate 25 moves toward the direction of the elliptical block 24. The horizontal plate 25 drives the clamping column 21 to move in the direction of the elliptical block 24, thereby moving away from the movable plate 20, thereby achieving the function of quickly releasing the fixation of the movable plate 20.

[0038] Further, such as Figure 1 As shown, a door frame 2 is provided on the outer side of the two door bodies 1 , and two hinges 3 are installed on the side walls of the door frame 2 adjacent to the two door bodies 1 .

[0039] During operation, the door body 1 is easily opened and closed by arranging the hinge 3 .

[0040] Further, such as Figure 1As shown, both ends of the door frame 2 are fixed with plugs 28, and fixing pins 29 are inserted in the plugs 28. Both ends of the door body 1 are fixed with two sleeves, and the sleeves are arranged on the outside of the fixing pins 29; both ends of the door body 1 are fixed with three limit blocks 30, and the fixing pins 29 cooperate with the limit blocks 30.

[0041] During operation, when the width of the door body 1 is wider, under the action of external force, the two door bodies 1 may rotate to form an angle, which will cause damage to the second connecting rod 7 and the first connecting rod 6; by moving the fixing pin 29 upward, one end of the fixing pin 29 enters the insert 28 on the door frame 2, and the other end of the fixing pin 29 is rotated to the upper limit block 30, and the fixing pin 29 is fixed by the limit block 30; when it needs to be opened, the fixing pin 29 is operated in reverse so that the fixing pin 29 is fixed by the next limit block 30.

[0042] Further, such as Figure 3 As shown, two limiting rods 11 are fixed to the inner wall of the cavity 14 , and both sides of the insertion rod 10 slide on the limiting rods 11 .

[0043] During operation, the insertion rod 10 slides on the limiting rod 11 during movement, and the limiting rod 11 limits the insertion rod 10 in a horizontal direction.

[0044] Working principle: When the door needs to be opened, two people operate a locking block 4 respectively, unlock the door through the locking block 4, and take out the second connecting rod 7. At the same time, another person operates another locking block 4, unlocks the door through the locking block 4, and takes out the first connecting rod 6. The second connecting rod 7 and the bottom of the first connecting rod 6 are respectively provided with a second speed sensor 9 and a first speed sensor 8. If the second connecting rod 7 and the first connecting rod 6 are taken out at the same time, the speed of the second speed sensor 9 and the first speed sensor 8 will change at the same time. By transmitting the signal to the computer program, the computer program controls the motor 26. By rotating the motor 26, the fixation of the horizontal plate 25 is released, and the interlocking block 5 can be rotated. The interlocking block 5 rotates 90°, exposing the latch 16 and the lock 18, and then the key is used. The lock 18 is unlocked, and the door closing operation is completed by the reverse operation of opening the door; when the locking block 4 is fixed, when the second connecting rod 7 is rotated downward and contacts the insertion rod 10, the insertion rod 10 is squeezed inward under the pressure of the second connecting rod 7, and the first spring 13 is compressed until the second connecting rod 7 is rotated to the bottom of the insertion rod 10. Under the action of the first spring 13, the insertion rod 10 is quickly reset to jam the second connecting rod 7; when the second connecting rod 7 needs to be removed, the push rod 12 is moved to drive the insertion rod 10 to move. When the insertion rod 10 moves, the first spring 13 is compressed, the insertion rod 10 contracts, and the second connecting rod 7 is rotated upward to remove the second connecting rod 7; the removal operation of the first connecting rod 6 is the same as the removal operation of the second connecting rod 7;

[0045] When the second connecting rod 7 and the second connecting rod 27 are opened at the same time, the motor 26 can be opened. When the motor 26 is turned on, the elliptical block 24 is driven to rotate by the output shaft of the motor 26. The squeezing of the cross plate 25 is released by the rotation of the elliptical block 24, and the cross plate 25 is moved in the direction of the elliptical block 24 under the action of the second spring 22. The card column 21 is driven by the cross plate 25 to move in the direction of the elliptical block 24, thereby moving away from the movable plate 20, and the fixing of the movable plate 20 is released by the motor 26. Then, by pulling the connecting rod 27 outward, the connecting rod 27 drives the movable plate 20 to move outward. The movable plate 20 no longer blocks the interlocking block 5, and the interlocking block 5 can be rotated. The lock 18 is opened by the key, and the first connecting block 2317 is rotated upward to leave the second connecting rod 27. By driving the first connecting block 2317, the latch 16 is moved to the fixed block 15 on one side. The other end of the latch 16 leaves the fixed block 15 at the edge, and the door can be opened.

[0046] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
