Abstract
The utility model relates to an improved theftproof door leaf with a built-in hinge. On the basis of the common theftproof door leaf, the utility model is additionally provided with a set of built-in hinge mechanism which is interlocked with a door lock, wherein the built-in hinge mechanism is composed of hinge shafts, a telescopic arm, a conduction rule, a detent board, an eccentric wheel, etc. When a door is locked, the top, the door leaf and the top, the bottom, the left and the right of a doorframe are connected together through the hinge shafts, so the theftproof performance of the door can be enhanced.
Description
The utility model relates to a kind of improved antitheft door leaf, belongs to the component of the doors and windows field.
At present, general door leaf in the construction work, be to make at the framework two sides of rough ground viscose fibre plate or veneer, this door intensity is low, non-anti-theft, can not satisfy the needs of house safety, many users have to be installed sheet metal door additional or at the coated metal sheet of the external surface of door leaf, though the door of this reinforcing has improved the difficulty of stealing door.But can not fundamentally address this problem, this is because burglars still can destroy door lock, thereby crime in the inlet chamber.
The purpose of this utility model is a kind of new antitheft door leaf of design, even this door still can not be opened door after door lock is destroyed, has very strong theftproof performance.
The purpose of this utility model realizes in the following way: be provided with a cover and door lock interlocking dowel mechanism together between the interior outer panels of door leaf framework; when locking a door, the lock shaft in this mechanism promptly inserts among the doorframe, like this; even door lock is destroyed, also can not be opened by shutter.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a left view.
Fig. 3 is the utility model scheme of installation.
Fig. 4 is the alarm electrical schematic diagram.
Present common door door leaf, by framework and be encapsulated in that interior outer panels on the framework forms, security door after improving, be between interior outer panels, be provided with one with door lock interlocking dowel mechanism together, dowel mechanism is by bearing pin 14, telescopic arm 11, conduction chi 2, pallet plate 4 and eccentric wheel 8 constitute, wherein, telescopic arm 11 is the L type, be respectively equipped with axis hole at its 3 end points, and by mandrel and bearing pin 14,2 one-tenth active connections of conduction chi, the effect of pallet plate 4 is for conduction chi 2 guiding, so be provided with guide groove 21 on it, on conduction chi 2, be provided with guide groove 20 and 22.They cooperate with guide shaft 3,28 on being fixed on door leaf, can make the conduction chi only move up and down.The conduction chi also is provided with allocating slot 23,24, they match with shift fork 9 on being loaded on eccentric wheel, can move up and down the conduction chi, during use, the moving circle of key revolution, promptly drive eccentric wheel and shift fork rotates a circle, and stir allocating slot 23 and move a tooth (guide groove 21 interoperations), correspondingly, allocating slot 24 also moves a tooth, and (spring hitch 10 is offset to the right, after having dialled tooth, set back again).Be provided with hole 18 in eccentric central authorities, door lock 3 is stirred chi and is promptly inserted in it.Like this, just the rotation that will lock and dowel motion of mechanism have been linked together.
The effect of base 1 is the basis that an installation is provided for each parts, and is fixed together with door leaf through it again, and cover plate 5 usefulness screws are fixed on the base, and a dished cover 6 is arranged on it, and eccentric wheel is positioned at promptly that it is recessed.
Press the security door of such scheme design, except that Door-lock bolt, the bearing pin of its built-in lock mechanism also connects together door leaf and doorframe, and, in order further to improve the burglary insurance coefficient, can add a telescopic arm 12 again, " Y " type that is shaped as of this telescopic arm, be respectively equipped with axis hole at its 3 end points, and by mandrel and bearing pin 26,27,2 one-tenth active connections of conduction chi.There is axis hole the centre of telescopic arm 12, and it is placed on the mandrel 19, can rotate freely around it, and mandrel then is fixed on the base plate 1, makes security door by this scheme, then all the linking together with doorframe up and down of door leaf further can have been improved theftproof performance.
The utility model also is provided with a cover alarm, and alarm is made up of buzzer FM and K switch 1, K2, and K1 is for often opening, and K2 is normally closed, and they and FM are serially connected with on the power supply jointly.K switch 1 is by spring leaf 25 controls, and the latter's one end is fixed on the base plate, and the other end is free state.Spring leaf is provided with a plush copper, and it matches with the plush copper that is located at conduction chi corresponding position, can stir the fine motion of the spring leaf left and right sides, thereby K switch 1 is opened and closed.K2 is fixed on the door leaf, and the spring leaf 7 of control K2 also is fixed on the door leaf, and simultaneously and a feeler lever fix, the latter then passes support 15 and stretches out door leaf.When door was closed, spring leaf was pressed towards K2, and normally closed interlock is opened, and then FM can not report to the police, and under improper situation, if do not turn the key in the lock, then K1 is in closure state, and K2 also is in closure state after opening the door, and then FM will report to the police.FM can adopt any audible alarm device.
Make antitheft door leaf by the utility model, can make all linking together up and down of door leaf and doorframe, strengthened the firmness of door.Under improper situation, also can in time report to the police, threaten the burglar, thereby improve the theftproof performance of door greatly.
