Abstract

The utility model relates to a cipher anti-theft door which is mainly controlled by a cipher lock and a clamping member gearing device. The clamping member gearing device is composed of the connections of a handle, a square shaft, a circular wheel, an upper and a lower inserts and a movable plug; a gap is arranged on the outer margin of the core shaft of the cipher lock. The movable plug can be controlled to be inserted into or separated from the gap of the core shaft by rotating a cipher and the handle, so that the inserts can be driven to be separated from or inserted into a door frame, and accordingly, a door leaf can be opened or locked easily. The door has the advantages of low cost, safe and convenient operation, and can easily further realize the functions of automatic warning, etc.

Description

Cipher anti-theft door

The utility model belongs to the technical field of building.

Normally used anti-theft door is outside existing wooden door, sets up the fence gate that theftproof lock is housed that one metal material manufactured again, improving safety, but the structure of this inside and outside twice door, the big and turnover inconvenience of investment.A kind of combined type anti-theft door is arranged on the market in recent years, only replace common twice door with one door, it is made up of doorframe, door leaf, theftproof lock and fastener, the framework and the lateral surface of doorframe, door leaf are all manufactured with metal material, theftproof lock on the door leaf can be controlled fastener with the doorframe interlock or separate, and reaches the purpose that makes door leaf arbitrarily close or open.The two pass door that this combined type anti-theft door is more common is saved material and expense, and it is few, easy to use to take up space, but because self is heavier, long-term use is sunk easily, tilted, and causes door leaf switch difficulty, and the device of lock is malfunctioning.

The purpose of this utility model is the deficiency that overcomes background technology, provide a kind of safer reliably, anti-theft door simply and easily.

The utility model is achieved in that

The cipher anti theft door is made up of doorframe 1, door leaf 2, coded lock 5 and fastener 3, the framework and the lateral surface of doorframe, door leaf are manufactured with metal material, edge has an axial gap 11 outside the mandrel 10 of coded lock, and fastener is interconnected and formed by handle 6, square shaft 8, circle wheel 9, last lower plunger 13, movable plug 12.When entering, Rotary puzzle lock makes it aim at the password of appointment, and movable plug is just aimed at the gap on the mandrel, the handle of dextrad rotation subsequently, make plug fall into gap by driving square shaft, circle wheel, the end of meanwhile going up lower plunger breaks away from doorframe, just can draw back door leaf and enter door.For preventing that outdoor personnel's mistake from confounding the password of coded lock, can insert pin after entering conveniently in the pin hole 14 of mandrel.Otherwise, if when going out, extract pin earlier, the dextrorotation handle, then movable plug is deviate from from the gap on the mandrel, Rotary puzzle lock thereupon, doorframe is just inserted in the end of last lower plunger, and door leaf is just by locking.This anti-theft door, cost is low, and is safe in utilization, convenient, and further realizes function such as automation warning easily.

Fig. 1, Fig. 2 are embodiment of the present utility model.

Fig. 1 is the overall structure figure of cipher anti theft door.1 is doorframe, and 2 is door leaf, and 3 is fastener, and 4 is opal, and 5 is coded lock, and 6 is handle, and 7 are lock commonly used.

Fig. 2 is the structural representation of coded lock and fastener, and left side figure is a locking states, and right figure is an opening.When entering, Rotary puzzle lock 4 makes definite password aim at certain position, so the movable plug 12 on the fastener is just aimed at the gap 11 of mandrel 10, the dextrorotation handle 6 thereupon, just drive square shaft 8, circle wheel 9, go up lower plunger 13, make movable plug enter gap, last lower plunger breaks away from doorframe 1, just can draw back door leaf 2 and enter door (as shown at right), in order to prevent that room stranger mistake from confounding the password on the coded lock, after entering, can order pin in the pin hole 14 that inserts on the mandrel conveniently.When going out, pull out pin earlier, right rotation handle again, just then movable plug breaks away from gap on the mandrel, the password of Rotary puzzle lock subsequently, last lower plunger just inserts doorframe, has reached the purpose (shown in left figure) with the door leaf locking.For safe more and convenient, can on door leaf, add one again common lock 7.

Claims (2)

1, a kind of cipher anti theft door, form by doorframe (1), door leaf (2), theftproof lock and fastener (3), the framework and the lateral surface of doorframe, door leaf are all manufactured with metal material, drive fastener and doorframe clamping or unlatching by theftproof lock, it is characterized in that: said theftproof lock is coded lock (5), the mandrel of coded lock (10) outer rim has a gap (11), and said fastener is one and mainly interconnects the transmission device of forming by handle (6), square shaft (8), circle wheel (9), last lower plunger (13), movable plug (12).

2,, it is characterized in that the mandrel of said coded lock has a pin (14) device according to the said door of claim 1.
