Detailed Description
The interlocking device comprises a rear upper door accessory 3 arranged on a rear upper door 6 and a rear lower door accessory 5 arranged on a rear lower door 4;
the rear upper door 6 and the rear lower door 4 are positioned on one side of the door frame 1, and the other side of the door frame 1 is connected with a U-shaped bent plate 2;
the upper part of the U-shaped bent plate 2 is provided with a U-shaped bent plate upper hole 21 for inserting the end part of the rear upper door accessory 3, and the lower part of the U-shaped bent plate 2 is provided with a U-shaped bent plate lower hole 22 for inserting the end part of the rear lower door accessory 5;
the end of the rear upper door accessory 3 can move up and down in the U-shaped bent plate upper hole 21, the end of the rear lower door accessory 5 can move up and down in the U-shaped bent plate lower hole 22, and the following interlocking conditions are met: when the rear upper door 6 is completely closed, the rear lower door 4 can be closed; when the rear upper door 6 is not completely closed, the rear lower door 4 cannot be closed.
Further, the end of the rear upper door accessory 3 inserted into the rear upper door 6 forms the following structure: the upper surface of the end part of the rear upper door accessory 3 forms a slope structure form, and the slope is matched with the U-shaped bent plate 2 and pushes the U-shaped bent plate 2 to move.
Further, the end of the rear lower door accessory 5 inserted into the rear lower door 4 forms the following structure: the upper surface of the end part of the rear lower door accessory 5 forms a slope structure form, and the slope is matched with the U-shaped bent plate 2 and pushes the U-shaped bent plate 2 to move.
Furthermore, the upper hole 21 and the lower hole 22 of the U-shaped bent plate form a long strip waist-shaped hole structure.
Further, an upper guide groove 23 is formed in the upper portion of the U-shaped bent plate 2, a lower guide groove 24 is formed in the lower portion of the U-shaped bent plate 2, and the U-shaped bent plate 2 can move up and down along the door frame 1 through the guide of the upper guide groove 23 and the lower guide groove 24.
The utility model is further explained with the following drawings to better understand the utility model: 1) the utility model discloses before door 6 is not closed completely in the back, when closing back lower door 4 earlier, because the higher authority of 5 front ends of back lower door annex is higher than U type bent plate lower hole 22 upper authorities, back lower door annex 5 can not pass U type bent plate 2 lower holes, consequently back lower door 4 can not close.
2) The rear upper door 6 is closed firstly, then the front end of the rear upper door accessory 3 pushes the U-shaped bent plate 2 to move upwards gradually along a slope, and after the rear upper door accessory 3 is completely closed, the upper edge of the rear upper door accessory 3 is overlapped with the upper edge of the upper hole 21 of the U-shaped bent plate.
3) After the upper back door 6 is completely closed, when the lower back door 4 is closed again, the front end of the lower back door accessory 5 gradually pushes the U-shaped bent plate 2 to move upwards continuously along the slope until the upper edge of the lower U-shaped bent plate hole 22 coincides with the upper edge of the lower back door accessory 5, and after the lower back door 4 is completely closed, the upper back door 6 cannot be opened because the lower edge of the upper U-shaped bent plate hole 21 is higher than the lower edge of the right-angled bend of the upper back door accessory 3.
The utility model discloses two annexs are fixed respectively at back upper door 6 and back lower door 4 backs, at 1 back welding two double-screw bolts of left door frame, 1 division has two upper and lower rectangular holes on the left side door frame, U type bent plate 2 is respectively opened from top to bottom has two guide ways (be respectively guide way 23 and lower guide way 24), two rectangular holes are opened to the centre, fix U type bent plate 2 at 1 back of left door frame through two nuts, and leave the clearance, guarantee U type bent plate 2 can be along two double-screw bolts vertical migration from top to bottom in the guide way. If the rear lower door 4 is closed first without closing the rear upper door 6, the rear lower door 4 cannot be closed because the U-bend plate 2 does not move upward and the front end of the rear lower door attachment 5 is blocked by the upper portion of the U-bend plate lower hole 22 and cannot pass through the lower hole 22 thereof. When the rear upper door 6 is closed first without closing the rear lower door 4, the rear upper door accessory 3 can pass through the left door frame upper hole and the U-shaped bent plate upper hole 21 and push the U-shaped bent plate 2 to gradually move upwards along the accessory slope until the rear upper door 6 is completely closed, and the upper edge of the rear upper door accessory 3 is superposed with the upper edge of the U-shaped bent plate upper hole 21. After the U-shaped bent plate 2 moves upwards, the front end of the rear lower door accessory 5 can penetrate through the lower hole 22 of the U-shaped bent plate and push the U-shaped bent plate 2 to gradually move upwards along the inclined plane of the rear lower door accessory 5 until the upper edge of the rear lower door accessory 5 is overlapped with the upper edge of the lower hole 22 of the U-shaped bent plate after the rear lower door 4 is completely closed. At this time, the rear upper door 6 cannot be opened because the lower edge of the U-bend upper hole 21 is higher than the lower edge of the quarter bend at the front end of the rear upper door attachment 3. With this interlocking device, it is possible to realize that the rear lower door can be closed only when the rear upper door is fully closed, and that the rear lower door cannot be closed when the rear upper door is not fully closed.
