Abstract

The utility model relates to an anti-following-up partition door, which comprises an inner door, an outer door, and a doorframe which are connected via hinges. The doorframe is fixed with an internal release gear, a mutual interlocking gear, and an external release gear. The inner and the outer doors are respectively fixed with a clamp tongue for pushing a pull rod to reach the goal of interlock. The novel anti-following-up partition door is added with an anti-following-up special device based on a prime prevention of burglary function, thus forming the special functions of double-door partition, opening interlock, and double open of emergency. Besides, the utility model overcomes the defect of single function of the existing security door, and the utility model can be widely used as containment facilities for various banks, coupon rooms, and other important occasions.

Description

Anti-following-up partition door

The utility model relates to a kind of door with antitheft anti-tracking, bulletproof function.

Present widely used security door only has anti-theft feature, and function singleness can not satisfy people's multiple needs, and addressing this problem becomes urgent need.

Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of simple in structurely, having of reliable operation be antitheft, anti-ly follow the tracks of, the Anti-following-up partition door of bulletproof function.

Task of the present utility model realizes as follows: it comprises door and the doorframe that connects by hinge Anti-following-up partition door, on doorframe, be fixed with interior release mechanism, outer release mechanism and mutual interlocking gear, it has a base plate mutual interlocking gear, be fixed with 5 supports on it, three pull bars are housed on support, return spring is housed on the pull bar, one of them pull bar right-hand member links to each other with a pivoted arm, left end links to each other with pull bar in the interior release mechanism, it has base plate outer release mechanism, and two supports are arranged on base plate, wherein is fixed with a push rod on the support and return spring is housed, push rod and button are turned round and are linked, another support is fixed with interior release mechanism, and it has base plate interior release mechanism, fixes two supports on the base plate, wherein be fixed with a pull bar on the support, return spring is housed on it, and the pull bar right-hand member is connected with mutual interlocking gear one pull bar, and left end and handle link, interior, block tongue all is housed on the external door, carries out interlocking in the grab of release mechanism inside and outside block tongue falls into.

The utility model is owing to be to have increased the ad hoc device of anti-tracking on the basis of security door original function, thereby the unique functions of form two-door partition, open interlocking, emergent pair being opened Anti-following-up partition door, under normal circumstances two-door working programme is an opening, door lock is dead in addition, one close, other opens by door, thereby realized the anti-tracking purpose of " two-door partition, open interlocking, emergent two opening ".

Fig. 1 is the utility model view;

Fig. 2 is the ad hoc apparatus structure view of anti-tracking;

Fig. 3 is the A-A sectional view of Fig. 2;

Fig. 4 is the left view of Fig. 2.

A most preferred embodiment of the present utility model, as figure, it comprises door and the doorframe that connects by hinge Anti-following-up partition door, on doorframe, be fixed with interior release mechanism, outer release mechanism and mutual interlocking gear 3, it has a base plate 17 mutual interlocking gear, fix 5 supports 18 on it, three pull bars 9 are housed on support, 15,16, return spring 10 is housed on the pull bar, one of them pull bar right-hand member links to each other with a pivoted arm 12, left end links to each other with pull bar in the interior release mechanism, it has base plate outer release mechanism, two supports are arranged on base plate, wherein be fixed with a push rod on the support, and return spring is housed, return spring is housed on the push rod, push rod and button are turned round and are linked, another support is fixed with interior release mechanism, and it has base plate interior release mechanism, fixes two supports on the base plate, wherein be fixed with a pull bar on the support, return spring is housed on it, and the pull bar right-hand member is connected with mutual interlocking gear one pull bar, and left end and handle link, interior, block tongue 14 all is housed on the external door, and block tongue falls into the grab 7 of inside and outside release mechanism, carry out interlocking in 13.

The course of work of this device is: all be in when opening when two-door, under the effect of return spring, pull bar is thrown off with grab makes the two-door locking state that all is in, and at this moment shuts wherein arbitrary, and this badge hook falls in the groove of block tongue, makes this door lock dead.Closing the door simultaneously, this block tongue overcomes the pressure of return spring, makes pull bar push another door to, and another grab is lifted, and removes locking state, and door just can be opened in addition.Thereby realize the external door unlatching, inside door is locked, the external door closure, and inside door is opened, and inside door is opened, and external door is locked, inside door closure, the unlatching interlock function that external door is opened.

When the two-door opening that all is in, simultaneously interior release mechanism cuts out, if at this moment external door is closed, external door is in locking state, locks the external door of also not opening with spoon, at this moment presses outer release mechanism, the external door grab is lifted, just can open external door.As need two-door while switch freely, we can spur interior release mechanism, rotation is blocked, (outward) badge hook in making all is in the state of lifting, and realizes the emergent pair of functions of opening.
