Abstract
The utility model relates to a steel anti-prizing door. The steel anti-prizing door comprises a hollow steel door body with a reinforcing rib. A lock case, an ordinary spring lock and a door mirror are arranged in a hollow chamber at the middle part of the door body, and the lock case is controlled by a lock core and can drive an upper and a lower guiding long arm lock rods to be simultaneously inserted in an upper and a lower doorframe lock holes and to be simultaneously restored. The utility model is characterized in that the upper and the lower guide long arm lock rods are movably connected with at least a side wall lock rod by an eccentric connecting plate. A positioning rotating shaft movably connected with a shaft seat fixed on the hollow door body is arranged on the eccentric connecting plate. The utility model has the advantages of reasonable structure, convenient opening, labor saving, long service life, prizing prevention, drilling prevention, fire prevention, teasing prevention and good shock resistance performance.
Description
The utility model belongs to a kind of class technical field for building, and particularly a kind of closed steel is anti-forces open the door.
Along with the policy of China reform and opening-up deepens continuously, people's living standard improves constantly, and people's pick-proof consciousness is also in continuous enhancing, thus dwelling house and office install anti-force open the door also in obvious increase.Anti-kind of forcing open the door in the market is a lot, mainly contain totally enclosed and semi-enclosed two kinds, wherein in more totally enclosed anti-forcing open the door, be to adopt empty belly door, and in empty stomach, be provided with the drive lock box of guide peg up and down by lock core control, although anti-the forcing open the door of this kind has certain pick-proof performance, also exist the lock point less, defectives such as the easy grasp of thief.
The purpose of this utility model provides a kind of anti-forcing open the door of steel that has the Multiple locking point of linkage.
The purpose of this utility model is achieved in that it comprises the empty stomach steel door body that has reinforcing rib, being provided with two the long-armed locking bars of guiding that drive up and down by lock core control in the cavity at door body middle part inserts in the lower door frame lockhole and lock box, and the common spring lock, peephole of return simultaneously simultaneously, it is characterized in that on the long-armed locking bar that leads up and down living at least by an eccentric junction plate is connected with a sidewall locking bar, eccentric junction plate be provided with one be fixed on the cavity door body on the positioning rotating shaft that is connected of axle bed cover work.During use, be arranged on long-armed locking bar and the interlock of sidewall locking bar in the body, drive by lock core that lock box realizes linking.
The utility model has been owing to increased the link gear of Multiple locking point on the basis of existing pick-proof door, therefore have rational in infrastructurely, and it is convenient, laborsaving to open, long service life, pick-proof, anti-drilling, fire prevention, anti-dialling and characteristics such as shock resistance is good.
Below in conjunction with accompanying drawing and by embodiment the utility model is further described.
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
By shown in Figure 1,1 is empty stomach steel door body, 2 is reinforcing rib, be equipped with common spring lock 3 in the side of door body, being provided with two the long-armed locking bars 5 of guiding that drive up and down by lock core control in the cavity at door body middle part inserts in the lower door frame lockhole and the lock box 4 of while return simultaneously, the middle and upper part of door body is equipped with a peephole 6, on the long-armed locking bar that leads up and down, respectively live and be connected with a sidewall locking bar 10 by an eccentric junction plate 7, eccentric junction plate be provided with one be fixed on the cavity door body on axle bed cover 8 positioning rotating shafts 9 of living and being connected, this positioning rotating shaft work is connected in the airtight axle bed that is full of lubricated glycerine overlaps.The sidewall with peephole groove relative position that hinge 11 places are installed is provided with two convex lock pins 12.In the cavity of door body, also be filled with the anti-material of noise reduction insulation in addition.During use, for a bit, linked by lock box by lock core two lead long-armed locking bar and two sidewall locking bars are that 4 and two convex lock pins are 2 points by common spring lock, have formed one at last and have had the anti-of 7 lockings and force open the door.Another kind of structure of the present utility model is by shown in Figure 2, and this structure is on the basis of Fig. 1, will be equipped with two tapered ends (having increased a tapered end) on the sidewall locking bar, and therefore, anti-forcing open the door shown in Figure 2 is that the anti-of 9 lockings forced open the door.
