The first padding column 2-9 can prevent the main U-shaped anti-prying plate from being seriously deformed due to the pulling force of the main door leaf bolt 2-10 on the main U-shaped anti-prying plate. The main door leaf bolt 2-10 is mainly used for preventing the connection between the main door leaf anti-prying steel piece 2 and the door leaf from loosening.
As shown in fig. 1, 2, 3, 4 and 7, the auxiliary door leaf anti-prying steel member 3 is a section bar and comprises a first auxiliary clamping plate 3-1, an auxiliary transition plate 3-2, an auxiliary U-shaped anti-prying plate and a second auxiliary clamping plate 3-3 which are integrally formed. The auxiliary U-shaped anti-prying plate consists of a first auxiliary anti-prying plate 3-4, an auxiliary middle plate 3-5 and a second auxiliary anti-prying plate 3-6 which are integrally formed. One side edges of the first auxiliary anti-pry plate 3-4 and the second auxiliary anti-pry plate 3-6 are respectively connected with two side edges of the auxiliary middle plate 3-5. One side edge of the auxiliary transition plate 3-2 is connected with the middle part of the first auxiliary clamping plate 3-1, and the other side edge is connected with the joint of the first auxiliary anti-pry plate 3-4 and the auxiliary middle plate 3-5 on the auxiliary U-shaped anti-pry plate. One side edge of the second auxiliary clamping plate 3-3 is connected with the side edge of the second auxiliary anti-pry plate 3-6 far away from the auxiliary middle plate 3-5 on the auxiliary U-shaped anti-pry plate. The first auxiliary clamping plate 3-1 and the second auxiliary clamping plate 3-3 are respectively contacted with the inner side face and the outer side face of the auxiliary door leaf 4 to form a state that the auxiliary door leaf anti-prying steel part 3 wraps the outer edge of the auxiliary door leaf 4, so that the assembling strength of the door leaf anti-prying steel part 2 is greatly enhanced. The distance from the first auxiliary anti-pry plate 3-4 to the axis of the hinge shaft of the main door leaf and the door frame 5 is greater than the distance from the second main anti-pry plate to the axis of the hinge shaft of the main door leaf and the door frame 5 and is less than the distance from the first main anti-pry plate to the axis of the hinge shaft of the main door leaf and the door frame 5. The distance from the second auxiliary anti-pry plate to the axis of the hinge shaft of the main door leaf and the door frame 5 is larger than the distance from the first main anti-pry plate to the axis of the hinge shaft of the main door leaf and the door frame 5. And an auxiliary sealing rubber strip 11 is fixed on one side of the inner side surface of the first auxiliary clamping plate, which is far away from the auxiliary door leaf 4. The main sealing rubber strip 10 and the second auxiliary clamping plate 3-3 are aligned along the circumferential direction of the axis of the hinge shaft of the main door leaf 1 and the door frame. The auxiliary sealing rubber strip 11 is aligned with the second main clamping plate 2-3 along the circumferential direction of the axis of the hinged shaft of the auxiliary door leaf 4 and the door frame. Third bolt in-out holes 3-7 are formed in the positions, corresponding to the main bolt 7 and the safety bolt 8, of the first auxiliary anti-pry plates 3-4.
N auxiliary door leaf bolts 3-9 are arranged on the auxiliary door leaf anti-prying steel piece 3, and n is 6. The n auxiliary door leaf bolts 3-9 are arranged in sequence along the length direction of the auxiliary door leaf anti-prying steel piece 3. All the auxiliary door leaf bolts 3-9 penetrate through the first auxiliary anti-prying plate 3-4, the second auxiliary anti-prying plate 3-6 and the outer edge of the auxiliary door leaf and are in threaded connection with the auxiliary door leaf reinforcing plate 6. All the auxiliary door leaf bolts 3-9 are sleeved with second cushion columns 3-8. All of the second studs 3-8 are located between the first secondary anti-pry plate 3-4 and the second secondary anti-pry plate 3-6. The length of the second bolster 3-8 is equal to the distance between the first secondary anti-pry plate 3-4 and the second secondary anti-pry plate 3-6. The second padding columns 3-8 can prevent the auxiliary U-shaped anti-prying plate from being seriously deformed due to the pulling force of the auxiliary door leaf bolts 3-9 on the auxiliary U-shaped anti-prying plate. The auxiliary door leaf bolts 3-9 are mainly used for preventing the connection between the auxiliary door leaf anti-prying steel part 3 and the door leaf from loosening.
The first main anti-pry plate 2-4 is provided with n main doorframe abdicating grooves 2-11. The outer ends of the n main door frame abdicating grooves 2-11 are communicated with the outer side edge of the first main anti-prying plate 2-4 (namely arranged in an open mode). The n main door frame abdicating grooves 2-11 are respectively aligned with the n auxiliary door leaf bolts on the auxiliary door leaf anti-prying steel piece 3, so that the first main anti-prying plate 2-4 is prevented from blocking the movement of the main door leaf bolt 2-10 groups.
The first auxiliary anti-pry plate 3-4 is provided with n auxiliary door frame abdicating grooves 3-10. The outer ends of the n auxiliary door frame abdicating grooves 3-10 are communicated with the outer side edge of the first auxiliary anti-prying plate 3-4 (namely arranged in an open mode). The n auxiliary door frame 5 abdicating grooves 3-4 are respectively aligned with the n main door leaf bolts 2-10 on the main door leaf anti-prying steel piece 2, so that the first auxiliary anti-prying plate 3-4 is prevented from blocking the movement of the main door leaf bolt 2-10 group.
The utility model discloses a theory of operation as follows:
when the main door leaf 1 and the auxiliary door leaf 4 in the utility model are closed, the first main anti-pry plate 2-4 extends between the first auxiliary anti-pry plate and the second auxiliary anti-pry plate, so that the main U-shaped anti-pry plate on the main door leaf anti-pry steel part 2 and the auxiliary U-shaped anti-pry plate on the auxiliary door leaf anti-pry steel part 3 form a cross-meshed state; meanwhile, the main bolt 7 sequentially passes through the first bolt in-out hole 2-7, the third bolt in-out hole 3-3 and the second bolt in-out hole 2-8, so that the main door leaf 1 and the auxiliary door leaf 42 are fixed together; in addition, the main sealing rubber strip 10 on the first main card 2-2 abuts against the second auxiliary card 3-3. The secondary sealing rubber strip 11 on the first secondary clamping plate is abutted against the second primary clamping plate. The main bead 10 and the sub bead 11 can reduce noise when the door is closed, and improve the sound insulation effect of the door.
After the main door leaf 1 and the auxiliary door leaf 42 are closed, even if a lawless person inserts tools such as a prying bar into a gap between the main door leaf prying-resistant steel part 2 and the auxiliary door leaf prying-resistant steel part 3, the prying bar can not enable the main lock tongue 7 to withdraw from the third lock tongue inlet and outlet hole 3-3 on the auxiliary door leaf prying-resistant steel part 3 under the blocking of the door leaf prying-resistant steel part 2, and a good prying-resistant effect is achieved.
Because the first main clamping plate 2-1 and the second main clamping plate 2-3 wrap the two sides of the main door leaf body 1. When a lawbreaker tries to forcedly destroy the connection between the main door leaf anti-prying steel piece and the first main clamping plate 2-1, the first main clamping plate 2-1 and the second main clamping plate 2-3 bear most of force; so that the connection between the main door leaf bolt 2-10 and the main door leaf is difficult to be damaged before a door prying person completely destroys the first main clamping plate 2-1. The first main clamping plate 2-1 covers the whole outer edge of the outer door plate 1-1, and the complete damage of the outer door plate is extremely difficult. Therefore, the utility model discloses a main door leaf pick-proof steel 2 resist violence broken ability of tearing open and be far greater than the pick-proof steel on the conventional pick-proof door. The principle of the anti-prying steel member of the auxiliary door leaf for resisting violent forcible entry is similar to that of the anti-prying steel member of the main door leaf, and the detailed description is omitted here.
