Abstract

The utility model relates to an inner linkage one-way safe metal door. The utility model is characterized in that an integral door leaf, a light transmission door leaf and a fireproof door leaf are respectively and orderly overlapped in a door frame through hinges, and door leaves are connected into a whole by a sleeve bolt with a handle; an inner linkage elastic door bolt and a fixed transverse bolt are arranged on the lateral face of the integral door leaf, and the opening and the closing of the inner linkage elastic door bolt and the fixed transverse bolt are controlled by the same lock core. The utility model has the characteristics of convenient use, little space occupation and good theftproof and fireproof performance. The door leaves connected into a whole can be simultaneously opened and closed towards one direction and divided into a single-leaf door to use, and the multiple lock bolt structure of the utility model solves of the shortage that doors are easily be prized; the utility model is suitable for theft prevention and fire prevention of important buildings of offices and enterprises and institutions and guesthouses, houses, etc. to use.

Description

The unidirectional safe metal door of interior interlock

The unidirectional safe metal door of interior interlock belongs to a kind of door with protection applications.

Mostly general security door design is outside original door, increases the metal lattice door one.Two fan door difference are switch in the opposite direction, has both taken than large space, is not easy to again use.The patent No. 902265849 discloses the unidirectional security door of a kind of bilayer, and its door links together with security door, and equidirectional switch uses but also each door is independent simultaneously.Have simple in structure, the little characteristics that take up room, but door lock still is single stud structure, antitheft, fire prevention poor reliability.

The purpose of this utility model is to provide the good interior interlock of a kind of anti-theft fireproof performance unidirectional safe metal door.

The utility model is to realize above-mentioned purpose like this.In doorframe, respectively with hinge on its step cross section successively closed assembly whole door leaf, printing opacity door leaf and fire prevention door leaf, and door leaf is connected as a single entity with the cover bolt of being with handle.In the cavity of whole door leaf side, interior interlock elasticity keeper and fixing horizontal bolt with same lock core gauge tap are housed.

The utlity model has easy to usely, it is little to take up room, the characteristics that the anti-theft fireproof performance is good.The door leaf that is connected as a single entity both can be separable into single door again and use towards direction switch simultaneously, and its many bolt structures have solved the deficiency that easy quilt is pried open, and was applicable to the anti-theft fireproof of office, enterprises and institutions' important building, and uses such as hotel and private residence.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the A-A sectional drawing of accompanying drawing one;

Accompanying drawing 3 is the B-C-D position profile figure of accompanying drawing one.

In the accompanying drawing one, whole door leaf (2) is installed on the doorframe (1) with hinge, and upper cross bolt (3), lower cross bolt (5) and elasticity keeper (4) are equipped with in its side.In the accompanying drawing two, on whole door leaf (2), printing opacity door leaf (6) and fire prevention door leaf (7) with hinge closed assembly successively.In the accompanying drawing three, be loaded in the framework cavity of whole door leaf (2) with the gear (8) of lock pin coaxial, the tooth bar (9) that is meshed with gear (8) is equipped with at connecting rod (10) middle part, and two ends join with bearing pin and junction plate (11).Horizontal bolt driving lever (12) one ends are fixed on the junction plate (11), and the other end is connected with horizontal bolt (3), (5) with bearing pin.

Embodiment of the present utility model is the private residence safety door, and door leaf is of a size of 200 * 80cm.Door leaf is divided into three layers, and first floor is whole lattice screen window door leaf, and the second layer is a glass printing opacity door leaf, and the 3rd layer is the steel door leaf of inner lining refractory, and three fan door leaf closed assemblies are one.Doorframe (1), door leaf (2), (6), (7), connecting rod (10), junction plate (11) and horizontal bolt driving lever (12) are processed with metal sheet roof covering and section bar, and the brass material manufacturing is used in horizontal bolt (3), (5), and elasticity keeper (4), gear (8) and tooth bar (9) they are outsourcing piece.
