Abstract

The utility model relates to a novel thief resistant door, which solves the technical problems of prior thief resistant door that the external lock closes to the door edge, thus the unlocking force is relatively high and uneven with few lock points and poor security. In order to solve the technical problems, the utility model comprises a door shell and an external lock on the door shell, which is characterized in that: the external lock is arranged in the middle of door shell of the thief resistant door. Because the utility model adopts the structure, a plurality of lock pins are arranged on the upper side, lower side, left side and right side of the door shell, thus greatly enhancing the connection strength of the door shell and doorframe, and enormously improving the thief resistant performance; in addition, the lock pins and connection rod are symmetrically disposed, thereby greatly reducing the force for switching the lock, and making smoothly operation.

Description

The novel anti-theft door

Technical field

The utility model relates to security door, specifically to having a kind of improvement of security door now.

Background technology

Generally be equipped with the external lock of switch outside and the internal lock of switch inside on antitheft every body in the market, external lock is near a door limit, and is corresponding with the interior lock position of the inside.Lock pin on the upper and lower door of the controlled control of external lock and the internal lock limit comes the switch security door.External lock comprises lock core and rotating disk and drives swing arm that rotating disk has only upper/lower terminal to be connected with two connecting rods, drives the turnover of swing arm driving connecting rod control gate body upper/lower terminal lock pin, with the open and close of control security door.Because external lock is near the door limit, asymmetric with the operating mechanism of inner lock pin, unlocking force is higher and inhomogeneous.In addition, owing to have only upper and lower door limit to be provided with lock pin, the lock point is few, the probability height that destructive external force is opened by force, the weak effect of safe antitheft.

Summary of the invention

The purpose of this utility model is in order to solve the close door of the security door external lock limit that prior art exists, unlocking force is higher and inhomogeneous, and technical problems such as lock is put less, poor stability, and a kind of theftproof performance that provides is good, anti-destructive coefficient height, and handle light novel anti-theft door.

In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solutions:

A kind of novel anti-theft door, it comprises the external lock on a body and the door body, it is characterized in that: described external lock is arranged on the centre of antitheft every body.

In the further detailed structure of the utility model, also has following technical characterictic: be equipped with lock pin on the upper/lower terminal of described door body and the and arranged on left and right sides frame.

In the further detailed structure of the utility model, also have following technical characterictic: described external lock comprises inner rotating disk and drives swing arm, rotating disk upper/lower terminal and and arranged on left and right sides all are connected with connecting rod, drive the lock pin of each connecting rod control gate body upper/lower terminal of swing arm driving and and arranged on left and right sides.

In the further detailed structure of the utility model, also have following technical characterictic: described lock pin and connecting rod all are that the center is symmetrical arranged with the external lock.

The utlity model has following advantage and good effect: because the utility model has adopted said structure, side is equipped with a plurality of lock pins in the upper and lower, left and right of door body, has strengthened the bonding strength of Men Tiyu doorframe greatly, has improved its theftproof performance greatly; In addition, being symmetrical arranged of lock pin and connecting rod, when having alleviated switch lock greatly firmly, make handle freely light.

The specific embodiment

Referring to Fig. 1-Fig. 7, the utility model security door comprises external lock 20, the internal lock 30 on a body 10 and the door body 10, and external lock 20 is arranged on the centre of antitheft every body 10, is equipped with lock pin 27 on the upper/lower terminal of described door body 10 and the and arranged on left and right sides frame 11.External lock 20 comprises inner rotating disk 22 and drives swing arm 23, rotating disk 22 upper/lower terminals and and arranged on left and right sides all are connected with connecting rod 25, drive the lock pin 27 that swing arm 23 drives each connecting rod 25 control gate bodies, 10 upper/lower terminals and and arranged on left and right sides, lock pin 27 and connecting rod 25 are that the center is symmetrical arranged with external lock 20 all.

External lock 20 is to drive each connecting rod 25 that swing arm 23 drives on the rotating disk 22, thereby drive each lock pin 27 and do switch motion, because the weight of left and right sides lock pin 27 and connector thereof is born by lock pin chute 271, when locking, only need overcome the friction of chute 271 and pilot pin 273 with hand switch; And upper and lower lock pin 27 and connector aspect thereof, through particular design, make the connecting rod 25 and the pin joint of rotating disk 22 depart from the vertical center line certain angle, like this when moving back and forth, the weight of the latch members of both sides up and down, the driving force of the other side's motion each other, kinetic moment and moment of resistance complete equipilibrium are offset, driving force during its switch lock is zero, and exerting oneself when having alleviated switch lock greatly handled very freely light.

Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
