[0027] Example

[0028] See also Figure 1-5 The utility model provides a technical solution: a world lock for an armored vehicle door, comprising a door body 1 installed on one side of the armored vehicle, one side of the door body 1 being rotatably connected to a rotating shaft 11 through a bearing, the rotating shaft 11 being located on one side inside the vehicle and being fixed with an inner handle 12, and the rotating shaft 11 being located on one side outside the vehicle and being fixed with an outer handle 14. Two lock tongue fixing blocks 10 are installed on the inner side of the door body 1. When it is necessary to open the door body 1 of the armored vehicle, when outside the vehicle, the outer handle 14 is rotated, and when inside the vehicle, only the inner handle 12 needs to be rotated, which drives the rotating shaft 11 to rotate. At the same time, the rotating shaft 11 drives the turntable 6 to rotate. When the turntable 6 rotates, the hinged upper locking rod 4 and the lower locking rod 7 are driven to rotate around the hinge point. A lock tongue 13 is movably passed through one side of the two lock tongue fixing blocks 10, the rotating shaft 11 is located inside the vehicle and is fixed with a turntable 6, and the upper locking rod 4 and the lower locking rod 7 are respectively hinged to the outer side of the turntable 6, and a locking assembly 5 is provided on one side of the turntable 6.

[0029] When the lock tongue 13 on the upper and lower sides of the door body 1 is close to each other, the lock tongue 13 leaves the inner side of the lock groove of the armored vehicle, and the door body 1 can be opened at this time. The user can open or close the door body 1 by simply turning the corresponding handle, which greatly simplifies the operation process and improves the convenience of use.

[0030] In order to facilitate locking the vehicle door body 1, a locking assembly 5 is provided. The locking assembly 5 includes a fixing frame 18, a sliding groove 21 is provided inside the fixing frame 18, and a slide plate 22 is slidably connected to the inner side of the sliding groove 21. When the vehicle door body 1 is opened from the outside by criminals, it only needs to rotate the lock column 19. At this time, the lock column 19 drives the limiting column 20 to rotate. At this time, the limiting column 20 slides and moves to the inner side of the second limiting groove 24. A lock column 19 that is movable through one side of the fixing frame 18 is fixedly inserted on one side of the slide plate 22. A lock hole 15 is provided on one side of the turntable 6. Under the elastic force of the second spring 17, the lock column 19 is pushed to the inner side of the lock hole 15. At this time, the turntable 6 cannot be rotated, and the vehicle door body 1 cannot be opened from the outside. The turntable 6 is kept stationary by the independent locking assembly 5, avoiding the failure of the linkage mechanism of the two lock tongues 13. The structure is simple and easy to manufacture. The invention has the advantages of easy operation, low maintenance cost, convenient operation and reliable use. The outer side of the lock column 19 is inserted into the inner side of the lock hole 15, and the second spring 17 is sleeved on the outer side of the lock column 19. The two ends of the second spring 17 are respectively connected to one side of the slide plate 22 and the slide groove 21. The outer side of the fixing frame 18 is respectively provided with a first limiting groove 23 and a second limiting groove 24 perpendicular to each other. The limiting column 20 is fixed on the outer side of the lock column 19, and one end of the fixing frame 18 is fixed to the inner side wall of the vehicle door body 1. The length of the second limiting groove 24 is greater than the length of the first limiting groove 23. By rotating the lock column 19, the limiting column 20 slides to the inner side of the second limiting groove 24, thereby preventing the turntable 6 from rotating, ensuring that the vehicle door body 1 can remain closed when it is illegally invaded from the outside, effectively preventing illegal entry of lawless elements, and improving the overall safety of the armored vehicle.

[0031] Working principle: When it is necessary to open the door body 1 of the armored vehicle, when outside the vehicle, turn the outer handle 14, and when inside the vehicle, only the inner handle 12 needs to be turned, which drives the rotating shaft 11 to rotate, and at the same time, the rotating shaft 11 drives the turntable 6 to rotate. When the turntable 6 rotates, the hinged upper locking rod 4 and the lower locking rod 7 are driven to rotate around the hinge point, and at the same time, the upper locking rod 4 and the lower locking rod 7 are brought closer to each other. The upper locking rod 4 and the lower locking rod 7 drive the adjusting sleeve 2, the lock tongue pull tab 8, the lock pin 9 and the lock tongue 13 to approach each other. When they are close to each other, the lock pin 9 can rotate to avoid interference. When the lock tongues 13 located on the upper and lower sides of the door body 1 approach each other, the lock tongue 13 leaves the inner side of the lock slot of the armored vehicle, and the door body 1 can be opened at this time. The user can open or close the door body 1 by simply turning the corresponding handle, which greatly simplifies the operation process and improves the convenience of use.

[0032] When the door body 1 needs to be closed, it is only necessary to turn the inner handle 12 or the outer handle 14, and then close the door body 1. At this time, under the elastic force of the first spring 3, the adjustment sleeve 2 and the lock tongue 13 are pushed toward the inner side of the lock groove of the vehicle body, and the door body 1 can be closed.

[0033] When the door body 1 is opened from the outside by criminals, it is only necessary to rotate the lock column 19. At this time, the lock column 19 drives the limiting column 20 to rotate. At this time, the limiting column 20 slides to the inside of the second limiting groove 24. At this time, under the elastic force of the second spring 17, the lock column 19 is pushed to the inside of the lock hole 15. At this time, the turntable 6 cannot be rotated, and the door body 1 cannot be opened from the outside. The turntable 6 is kept stationary by the independent locking component 5, thereby avoiding the failure of the linkage mechanism of the two lock tongues 13. The structure is simple, easy to manufacture, low maintenance cost, convenient operation, and reliable use. It is suitable for the sky and earth lock structure with single or double doors in armored vehicles. By introducing the independent locking component 5, when criminals try to open the door body 1 from the outside, the lock column 19 can be rotated to make the limiting column 20 slide to the inside of the second limiting groove 24, thereby preventing the turntable 6 from rotating, ensuring that the door body 1 can remain closed when illegally intruded from the outside, effectively preventing illegal entry of criminals, and improving the overall safety of the armored vehicle.

[0034] The locking assembly 5 has a simple structure. Once a failure occurs or maintenance is required, the maintenance cost is relatively low, which is of great significance for the long-term use and maintenance of armored vehicles. It can reduce vehicle maintenance costs and improve economic benefits. When the door body 1 needs to be opened, it is only necessary to pull the lock column 19 to one side and rotate the lock column 19 so that the limit column 20 moves to the inside of the first limit groove 23. At this time, the lock column 19 leaves the inside of the lock hole 15, and the inner handle 12 or the outer handle 14 can be rotated to open the door body 1.
