Description

Internally opened plate anti-theft door

The utility model relates to drives board-like security door in a kind of.

The security door of Sheng Chan,Xiao Shouing mostly installs additional outside entry door in the market, belongs to outward opening door.The security door of this form only is equipped with a door lock (limit lock), and easily destroyed, safety is relatively poor.This security door and entry door have constituted two sects, and the unlatching formality is cumbersome, use inconvenience, and material consumption are bigger.For every layer three unit resident family, after opening, security door interacts, and consumers' opinions is bigger.In addition, various types of security doors are the framework bar construction, give the sensation of a kind of prison of people.Also because this class security door all adopts common hinge, it is bigger to rub when starting, and cluck,coo noise occurs easily.

The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned background technology, and design a kind of function that collects timber and security door is one, and it is lighter to have weight, easy to use, do not take stairway spaces, install easily and the pick-proof effect is driven board-like security door preferably.

The utility model is achieved through the following technical solutions.Drive board-like security door in this and comprise doorframe and door-plate, the limit lock is positioned at one side of door-plate, and sight glass is installed on the door-plate.The middle lock that one dead bolt can stretch out to both sides is housed in door-plate, and an end of lock fork is connected with dead bolt, and the other end passes the frame of door-plate, and doorframe is provided with lock and cheats.Be connected by hinge between door-plate and the doorframe, on the axis of hinge, be with lining, be respectively equipped with buttonhole and lock pin on two of hinge.The lock fork is vertically laid in door-plate, and the space filling in the door-plate has the heat-insulating flame-retardant expanded material.

Fig. 1: structural representation of the present utility model.

The contour structures schematic diagram of Fig. 2: Fig. 1.

Fig. 3: the structural representation of hinge.

The plan view of Fig. 4: Fig. 2.

Now in conjunction with the accompanying drawings the utility model is explained as follows:

As shown in Figure 1, door-plate 3 inside of this security door are a frame construction, and fixedly mounting a dead bolt at the middle part of door-plate 3 can be to the flexible middle lock 7 in both sides, and two dead bolts 6 of this centre lock 7 are connected with lock fork 5 respectively.Lock fork 5 is vertically vertically laid with door-plate 3, and lock fork 5 can pass the upper and lower frame of door-plate 3 and extend in the lock hole 4 of doorframe 2 and play the locking effect.Lock 1 on one side in the usual position peace that door lock is installed, this limit lock 1 preferably uses ball catch.Referring to Fig. 2, inside and outside of door-plate 3 all clads with steel sheet, and the lockhole of limit lock 1, middle lock 7 is only left in door-plate 3 fronts, and sight glass 10.Doorframe 2 preferably adopts metal frame or clad steel sheet on wooden door frame and forms.Being connected by hinge 8 between door-plate 3 and the doorframe 2 realizes.For frictional resistance and the noise that overcomes common hinge, on the axis 12 of hinge 8, also be provided with a copper lining 13, and on two of hinge 8, be respectively equipped with a buttonhole 11 and lock pin 14() referring to Fig. 3, Fig. 4.After door-plate 3 and doorframe 2 closures, two of hinge 8 also just merge, and buttonhole 11 buckles into lock pin 14, play fastening and prevent the effect that destroys.Space in door-plate 3 also is filled with normally used anti-flaming thermal-insulation expanded material 9.

When owner enters house, open limit lock 1 and centre lock 7 with key, at this moment, lock fork 5 withdrawals that are connected with the dead bolt 6 of centre lock 7 and the lock hole 4 on the disengaging doorframe 2, door-plate 2 can be pushed open to indoor around hinge 8.When the indoor people of having came in and went out repeatedly, limit lock 1 and middle lock 7 did not all need locking, and 1 on limit lock plays the pearl effect of bumping of temporarily closing the door.When the chamber owner need go out or during rest, from the indoor or outdoors locking, the installation of sight glass 10 can be indoor observation messenger and other situation outdoors to available key easily with limit lock 1 and middle lock 7.

Because this structure design, when door-plate and doorframe are sealed, there are limit lock and upper and lower two to lock four points and two hinge totally seven dotted or gate frames combinations of pitching, strengthened the pick-proof ability.

The utility model collection tradition timber and security door are one, and be easy for installation, can save a large amount of timber, adds 7 junctions of doorframe and door-plate, uses general tool used in crime can't be pried open destruction, really plays antitheft effect.This door is an inner-opening type, does not take stairway spaces, has also made things convenient for the pedestrian in neighbours and upper and lower building.The common security door of this weight ratio is light, again because of the particular design of hinge, makes that door switch is flexible, sound is less.The expanded material of filling can play heat insulation, sound insulation, fire-retardant effect in the door-plate.
